+
+## GENERAL REQUIREMENTS FOR THE INTERWORKING OF THE TERRESTRIAL TELEPHONE NETWORK AND INMARSAT STANDARD A SYSTEM
+
+## 1 Introduction
+
+1.1 The purpose of this Recommendation is to define the general interworking requirements between the telephone network and the INMARSAT Standard A system.
+
+1.2 In order to support automatic working between subscribers in the public telephone service and telephone subscribers to the maritime mobile-satellite service, it is necessary that the interface between the terrestrial telephone network and the maritime satellite system be defined.
+
+1.3 It should be possible to interface the maritime-mobile satellite system with any signalling system standardized by the CCITT for automatic working. In order to facilitate the preparation of the interworking equipment, and also aiming at the international standardization of the service, this Recommendation lists several basic interworking requirements common to all signalling systems.
+
+1.4 More specific interworking requirements applicable to System No. 5 are given in Recommendation Q.1103 and System R2 are given in Recommendation Q.1102.
+
+1.5 A brief description of the INMARSAT Standard A system is given in Annex A. SDL descriptions of incoming and outgoing signalling procedures for the INMARSAT system are given in Annexes B and C respectively.
+
+1.6 Interworking between the telephone network/ISDN and other INMARSAT systems is given in separate Q-Series Recommendations.
+
+## 2 Maritime satellite switching centre
+
+For the purpose of this Recommendation the term Maritime Satellite Switching Centre (MSSC) is used to indicate the interworking point between the terrestrial telephone network and the maritime satellite system. The maritime satellite switching centre (MSSC) may be located at the antenna site of the coast earth station [1] and operate as an independent international switching centre connected to one or more international switching centres (ISCs) or national switching centres, or it may be remote as a supplement to or as a part of an international switching centre.

+
+## 4 Sending sequence of numerical (or address) signals
+
+### 4.1 *Calls toward ship earth station [2] (shore-to-ship)*
+
+In most cases the MSSC will not need the information contained in the S-digit of the country code 87S. In this situation the sequence of forward-address information sent to the MSSC should be as for a terminal international call.
+
+Cases may arise where an MSSC requires the S-digit to distinguish between ocean areas, satellite systems or VHF/UHF vs. satellite. In this situation the sequence of forward-address information should be as for an international transit call, i.e. the sequence includes the country code 87S.
+
+### 4.2 *S-digit*
+
+It is a matter for the terrestrial subscriber to choose the proper S-digit and the MSSC to be used will be decided by the outgoing country. (For technical reasons accounting between Administrations should be performed on the basis of only 87S.)
+
+### 4.3 *Calls from ship earth station (ship-to-shore)*
+
+The desired MSSC is selected at the ship earth station by procedures within the maritime satellite system. After the dialling tone has been provided to the subscriber, he will dial a prefix followed by the full international telephone number required, whether or not the MSSC is located in the required subscriber's country (see also Recommendation Q.11*quater*).
+
+The prefix must be suppressed by the MSSC since it is only required for internal routing in the MSSC.
+
+For calls to subscribers in the MSSC country, the country code should also be suppressed by the MSSC.
+
+A discriminating digit must be inserted by the MSSC according to Recommendation Q.104.
+
+### 4.4 *Operator services*
+
+The desired MSSC is selected at the ship earth station by procedures within the maritime satellite system. After the dialling tone has been provided to the subscriber, he will dial a two digit prefix, possibly followed by a 1, 2 or 3 digit country code, to identify the type of operator required (see Recommendation Q.11*quater*).
+
+The MSSC could then convert the received dialling information as required for setting up the terrestrial connection to the operator.
+
+### 4.5 *Special service terminations*
+
+The desired MSSC is selected at the ship earth station by procedures within the maritime satellite system. After the dialling tone has been provided to the subscriber, he will dial a two digit prefix possibly followed by other digits to identify the type of special service termination required. (See Recommendation Q.11*quater*.) The MSSC should convert the received dialling information as required for setting up the terrestrial connection.
+
+## 5 Special requirements related to setting-up and clearing of automatic calls
+
+### 5.1 *Setting-up time for shore originated calls*
+
+The setting-up time for shore originated calls should be as short as possible. If the MSSC has not been able to establish the connection within a period of 20 seconds after receipt of all address digits, a congestion indication should be returned.
+
+*Note* - In maritime satellite systems the setting-up time is not controlled by each individual MSSC but may depend on the overall traffic load in the system and on the assignment procedure used. For several reasons the setting-up time of the radio path is likely to be longer than the setting-up time of the subscriber connection in terrestrial systems.
+
+### 5.2 *Transmission of answer signal*
+
+5.2.1 When the maritime satellite switching centre (MSSC) detects the answer signal from the maritime satellite system, the MSSC must remove the ringing tone, through-connect the circuit and return the answer signal as soon as possible to the terrestrial switching centre.
+
+Precautions should be taken at the MSSC to avoid interpreting an interruption of the satellite link as an answer signal.
+
+5.2.2 For ship originated calls the maritime satellite system should preferably include provisions for transferring the answer signal to the ship earth station.
+
+### 5.3 *Seizure of a terrestrial circuit from the MSSC*
+
+The maritime satellite switching centre should not seize a terrestrial circuit before each of the following conditions has been met:
+
+- the satellite channel has been assigned;
+- the continuity of the satellite channel has been verified;
+- all digits necessary for routing decision by the maritime satellite switching centre have been received.
+
+### 5.4 *Clear-back conditions*
+
+5.4.1 The clear-back/re-answer sequence may not apply for shore originated calls, in which case the satellite link will be released when a clear-back signal is detected at the maritime satellite switching centre from the satellite link, without waiting for a clear-forward signal from the terrestrial network.
+
+Precautions should be taken either at the MSSC or at the ship earth station in order to avoid unintentional clearing.
+
+5.4.2 For ship originated calls the normal clear-back procedures should apply (see Recommendation Q.118).
+
+### 5.5 *Clear-forward*
+
+When detecting a clear-forward from the satellite link, the MSSC should immediately pass the clear-forward signal into the terrestrial network.
+
+When detecting a clear-forward from the terrestrial network, the release guard (and clearing) sequence should follow the procedures defined for the signalling system used.
+
+### 5.6 *Splitting arrangement*
+
+When in-band signalling is used over the satellite link for setting-up and clearing of the link, a splitting arrangement shall be provided in order to avoid that signalling tones are passed into the terrestrial network. The splitting time shall be less than 20 ms.
+
+In order to protect the maritime satellite system from line signals used on terrestrial signalling systems, it should be observed that such signalling tones passing through splitting arrangements in the terrestrial network may have a maximum duration of 50 ms.
+
+## 6 Audible tones sent by the MSSC
+
+Tones sent by the maritime switching centre (MSSC) should have the following characteristics:
+
+|                           |                                                                                    |
+|---------------------------|------------------------------------------------------------------------------------|
+| Dial tone:                | 425 Hz (1.5 seconds maximum, minimum is determined by receipt of first dial digit) |
+| Ringing tone:             | 425 Hz (1 second on, 4 seconds off, immediate ringing)                             |
+| Busy tone:                | 425 Hz (1/2 second on, 1/2 second off)                                             |
+| Congestion tone:          | 425 Hz (1/4 second on, 1/4 second off)                                             |
+| Special information tone: | as defined in Recommendation Q.35.                                                 |
+
+*Note* - The dial tone is given as 1.5 seconds pulse in order to avoid subscribers' confusion due to the two-way transmission delay of 0.5 seconds. If the normal continuous tone with interruption after the receipt of the first digit was used, the delay would cause the tone to stay on after entry of the first digit.
+
+## 7 Control of echo suppressors
+
+Since all calls to and from a ship earth station will include a satellite link, appropriate actions must be taken to insert an incoming or outgoing half-echo suppressor at the MSSC or at an international exchange closer to the terrestrial subscriber. The ship earth station will connect to the satellite link on a 4-wire basis or will be provided with the equivalent of a half-echo suppressor. In order to reduce the analysis and control requirements at the MSSC it may prove convenient to carry out all echo suppressor control at one of the international exchanges rather than at the MSSC. This is most easily achieved by fitting permanent half-echo suppressors at the ISC end of each MSSC-ISC circuit. In any case the overall echo control requirements are the same as specified in Recommendation Q.115.
+
+### 7.1 *Terrestrial signalling systems with signals for control of echo suppressors*
+
+#### 7.1.1 *Ship original calls*
+
+The MSSC should send an echo suppressor indicator informing transit centres or incoming centres whether or not an incoming half-echo suppressor should be included.
+
+Insertion of an incoming half-echo suppressor will always be requested if the MSSC does not carry out echo suppressor control.
+
+#### 7.1.2 *Shore originated calls*
+
+The MSSC will decide whether or not to insert an outgoing half-echo suppressor depending on the received echo suppressor indicator. If echo control is not performed at the MSSC, the echo suppressor indicator will always inform the MSSC that an outgoing half-echo suppressor has already been included.
+
+### 7.2 *Terrestrial signalling systems without signals from control of echo suppressors*
+
+When signals for the control of echo suppressors are not available on the particular terrestrial route, significant advantage is to be gained by carrying out the echo suppressor control at the international exchange. In any case the following rules should be observed:
+
+#### 7.2.1 *Ship originated calls*
+
+- When the terrestrial connection between the outgoing ISC, (or MSSC) and the incoming ISC (or national incoming switching centre) does not normally require the use of echo suppressors, the outgoing ISC (or MSSC) should enable (or insert) an incoming half-echo suppressor associated with the satellite link.
+- When the terrestrial connection between the outgoing ISC (or MSSC) and the incoming ISC (or national incoming switching centre) normally requires the use of echo suppressors, the outgoing ISC (or MSSC) should disable (or should not insert) any half-echo suppressors associated with either the satellite link or the terrestrial link.
+
+#### 7.2.2 Shore originated calls
+
+- When the international connection between the outgoing ISC and the incoming ISC (or MSSC) does not normally require the use of echo suppressors, the incoming ISC (or MSSC) should enable (or insert) an outgoing half-echo suppressor associated with the satellite link.
+- When the international connection between the outgoing ISC and the incoming ISC (or MSSC) normally requires the use of echo suppressors, the incoming ISC (or MSSC) should disable (or should not insert) any half-echo suppressors associated with either the satellite or terrestrial link.
+
+## 8 Handling of group calls
+
+### 8.1 General
+
+A group call is a simultaneous call to a given group of ships. Such calls are identified by the following international number:
+
+$$87S0X_2X_3 \dots X_k$$
+
+where the first digit of the ship station number has the fixed value 0. The remaining digits determine which group of ships is being addressed.
+
+Facilities for originating group calls from operators either in the MSSC country or another country may be readily made available by permitting such calls only when the Z digit is a language digit. Group calls originating from ordinary telephone subscribers should not be permitted so long as calling line identification is not available.
+
+### 8.2 Barring at the ISC of origin
+
+In order to avoid setting up of the international chain for unauthorized group calls from ordinary subscribers, barring of such calls should, as a general rule, be done at the ISC of origin.
+
+### 8.3 Barring at the MSSC
+
+Barring should also be provided at the MSSC in order to reject group call attempts from ships or from subscribers in countries where barring at the outgoing ISC is not possible.
+
+## 9 Avoiding two or more satellite links in tandem
+
+### 9.1 Shore originated calls
+
+The country code 87S should be analysed at all transit centres where the call may either be routed on a circuit containing a satellite link or on a circuit not containing a satellite link. The latter circuit should always be chosen (see Recommendation Q.14).
+
+### 9.2 Ship originated calls
+
+If the signalling system provided between the MSSC and the terrestrial network contains signals which may be used to indicate that one satellite link is included, such signals should be used.
+
+If the signalling system does not contain such signals, the outgoing ISC should avoid forwarding the call on an outgoing circuit which includes a satellite link. If, however, the signalling system employed between the outgoing ISC and the next ISC in the connection contains such signals, the outgoing ISC should insert the required information. The outgoing ISC could base its procedure upon incoming route identification.
+
+## 10 Operator assistance for semi-automatic shore originated calls
+
+If code 11/12 assistance facilities are not provided at the MSSC, then arrangements should be made to intercept such calls at the preceding ISC and route them to an appropriate operator.
+
+It may be advantageous for Administrations to provide a publicized number (e.g. C12XXXX) for specialized assistance on calls to the maritime network.
+
+## ANNEX A
+
+(to Recommendation Q.1101)
+
+### **Brief description of the INMARSAT Standard A system**
+
+### A.1 *Introduction*
+
+This annex describes the signalling in the INMARSAT Standard A system in a multiple Maritime Satellite Switching Centre (MSSC) configuration, i.e., there is more than one MSSC serving an ocean region. Automatic call set-up and clearing are illustrated below. For calls which cannot be completed, the subscriber will receive from the MSSC or the terrestrial network the proper audible tone which describes the call status (i.e., busy tone, congestion tone).
+
+### A.2 *System configuration*
+
+The INMARSAT system is composed as shown in Figure A-1/Q.1101. Only the components required for interfacing the telephone network are shown. There are additional interfaces similar to the MSSC for interfacing the telex network and the international public data network.
+
+The purpose of the MSSC is defined in § 2 of the Recommendation.
+
+There is one operating Network Coordination Station (NCS) in each ocean area (there may in addition be one or more standby NCSs per ocean area). The main functions of the NCS are as follows.
+
+The ship earth stations can only monitor one calling channel in the shore-to-ship direction. This calling channel, denoted as the common assignment channel, is transmitted by the NCS. Each coast earth station transmits its own calling channel which is monitored by the NCS for relaying signalling messages from a coast earth station to a ship.
+
+The NCS also performs all assignment of telephone channels on a call-by-call basis and monitors the actual use of the channels for maintenance purposes. The NCS keeps an up-dated list of all busy ships in the ocean area. If a coast earth station calls a busy ship, the NCS may thus return a ship busy indication to the calling coast earth station on the common assignment channel.
+
+The procedures are further described below.
+
+### A.3 *Ship earth station originated calls*
+
+The normal call set-up procedure for automatic call processing from a ship earth station is shown in Figure A-2/Q.1101. The ship earth station transmits an out-of-band request message which includes the type of call desired, the identify of the MSSC through which the terminal wishes to communicate and the identification number of the ship earth station.

+
+FIGURE A-1/Q.1101
+
+#### **Composition of the maritime satellite system for interconnection with the telephone network**
+
+The MSSC upon reacting to the received *request* message, sends a *Request for Assignment* message to the Network Coordination Station (NCS). The NCS receiving the *request for assignment* message assigns a channel (frequency) and transmits this information in an *assignment* message to both the MSSC and the ship earth station. Both the MSSC and ship earth station receive the *assignment* message, automatically select the correct frequency, and initiate a continuity by transmitting a 2600 Hz tone.
+
+When continuity has been established, the MSSC sends a dial tone pulse to the ship earth station. The ship earth station subscriber then dials in the desired prefix, country code and national significant number followed by an end-of-selection signal. The signals are transferred as in band push button signals on the satellite link.
+
+The MSSC proceeds to select a terrestrial trunk and follows the standard signalling sequences of the signalling system used towards the ISC (Figure A-2/Q.1101). The ringing tone from the terrestrial network is allowed to pass directly to the ship earth station subscriber. When the terrestrial party answers the call, the ISC passes the answer signal to the MSSC and the international connection is established. The answer signal, if implemented, may then be passed to the ship earth station<sup>1)</sup>.
+
+### **A.4 Terrestrial originated calls**
+
+The normal call set-up procedure for automatic call processing from the terrestrial network to a ship earth station is shown in Figure A-3/Q.1101. The ISC selects a circuit and sends the seizing signal and the mobile terminal identification digits to the MSSC in accordance with the procedures used in the terrestrial signalling system. The MSSC then sends a *request-for-assignment* message to the NCS containing the ship earth station identity. The NCS responds by sending an *assignment* message to both the MSSC and the ship earth station. The MSSC and the ship earth station activate their carriers and send a 2600 Hz tone. Upon receipt of the 2600 Hz tone from the ship earth station the MSSC interprets this as an address complete condition, sends the ringing tone to the terrestrial network and stops sending 2600 Hz to the ship earth station. When the operator or subscriber at the ship earth station answers, the ship earth station discontinues sending its 2600 Hz tone.
+
+The MSSC recognizes the cutting of the 2600 Hz tone as an answer signal from the ship earth station and begins the answer sequence toward the ISC as shown in Figure A-3/Q.1101.
+
+<sup>1)</sup> This is currently under study by INMARSAT.

+![Sequence diagram for ship earth station originated calls (Figure A-2/Q.1101).](a5ee5c23b6dc52ec1d724b76d5a5f58f_img.jpg)
+
+This sequence diagram illustrates the call setup process for a ship earth station originated call. The participants are the Ship earth station, Network coordination station (NCS), Addressed maritime satellite switching centre, and ISC. The process begins with a 'Request' from the ship to the NCS, followed by a 'Request for assignment' from the NCS to the switching centre. An 'Assignment' message is returned from the switching centre via the NCS to the ship. A 'continuity check' is performed between the ship and the switching centre, involving 'SF tone on', 'Carrier on', and 'SF tone off' signals. A '1,5 s Proceed-to-select tone' is sent from the switching centre to the ship. 'Subscriber keying' is indicated at the ship. 'Digits (human cadence)' are sent from the ship to the switching centre. The switching centre sends a 'Seizing' signal to the ISC, followed by 'Inter register signalling'. A 'Ringing tone' and 'Answer' are exchanged between the switching centre and the ISC. Finally, a 'Cut through' is established between the ship and the ISC, and the call is in progress. The diagram is labeled CCITT-39262.

+
+### A.5 Automatic clearing of calls
+
+Whether a telephone call originated from a ship earth station or from the terrestrial network, the MSSC, upon receiving a clear-forward signal, will begin to clear the call independently in each direction.
+
+The MSSC, receiving a 2600 Hz clearing tone from a ship earth station will initiate clearing toward the terrestrial network in accordance with procedures defined for the signalling system used between the MSSC and the ISC. This applies to both clear-forward and clear-back from the ship earth station. Clearing will also be continued in the maritime satellite system independent of the terrestrial network.
+
+Clearing initiated in the terrestrial network would be recognized by the MSSC receiving the appropriate clear-back or clear-forward signal. For clear-forward, the MSSC would continue clearing with normal terrestrial procedures and begin clearing the maritime satellite circuit. For clear-back from the terrestrial network, normal time-out supervision will take place and clear-forward will commence either after expiry of time-out or after receipt of a clear-forward from the ship, whichever happens first.
+
+As examples of clearing sequences, Figure A-4/Q.1101 illustrates the clearing of a ship earth station originated call and Figure A-5/Q.1101 illustrates the clearing of a call originated in the terrestrial network. For a terrestrial originated call which has clearing initiated by the ship earth station, the satellite circuit is cleared after the MSSC recognizes the stopping of the ship earth station carrier. The terrestrial circuit is held until the end of release guard sequence as shown in Figure A-5/Q.1101.

+![Flowchart of Incoming INMARSAT Standard A signalling system. The process starts at IDLE (00), receives a REQUEST FROM SHIP, STORES the MESSAGE, and SETS UP the SATELLITE CHANNEL (with INMARSAT system supervision). It then enters WAIT FOR CONTINUITY (01). If CONTINUITY ESTABLISHED, it sends SPITE 6 CONNECT DIAL TONE, then SPITE 1, and STARTS t1 (15-20 seconds). If UNSUCCESSFUL CALL, it DISCONNECTS the SATELLITE CHANNEL (with INMARSAT system disconnection procedure) and returns to IDLE (00). After START t1, it enters WAIT FOR DIGITS (02). From here, ADDRESS SIGNAL, CLEAR FORWARD, or t1-bar can occur. ADDRESS SIGNAL leads to END OF PULSING. If YES, it goes to SPITE 35, STOP t1, STORE END-OF-PULSING DIGIT, then SPITE 12 (Note 1), and connector 2. If NO, it checks SPITE 11. If YES, it goes to START t1 and connector 1.

+
+The flowchart illustrates the signalling logic for an incoming INMARSAT Standard A call. It begins at connector 2, leading to state 03 (WAIT FOR RESULT OF DIGIT ANALYSIS). From here, multiple signal inputs are monitored: ADDRESS SIGNAL, SPITE 15, 16, 17, 18, 19, SPITE 13, SPITE 14 (Note 2), CLEAR-FORWARD, and  $t_1$ .
+
+- The **ADDRESS SIGNAL** path leads to a decision 'END OF PULSING'. If 'NO', it triggers 'START  $t_1$ '. If 'YES', it proceeds to 'STOP  $t_1$ ', 'STORE END-OF-PULSING DIGIT', and 'SPITE 35', returning to connector 2.
+- The **SPITE 15, 16, 17, 18, 19** path leads to 'YES' or 'NO' for 'EoP RECEIVED'. If 'YES', it triggers 'STOP  $t_1$ ', 'SPITE 6', and 'SPITE 3', then 'START  $t_2$ ' (where  $t_2 = 20-30$  seconds), leading to state 06 (WAIT FOR CLEAR-FORWARD). From state 06, 'CLEAR-FORWARD' leads to 'STOP  $t_2$ ' and connector 4. If 'EoP RECEIVED' is 'NO', it returns to connector 1.
+- The **SPITE 13** path returns to connector 1.
+- The **SPITE 14 (Note 2)** path leads to 'ACTIVATE INTER-WORKING PROCEDURE' and 'WHICH CATEGORY'. Categories include 'Ordinary call' (FITE 17), 'Priority call' (FITE 18), and 'Data call' (FITE 19), all leading to 'FITE 1'. 'FITE 1' leads to 'ANY MORE DIGITS'. If 'YES', it triggers 'START  $t_1$ '. If 'NO', it leads to state 04 (WAIT FOR CALL SET-UP).
+- The **CLEAR-FORWARD** path leads to 'STOP  $t_1$ ' and connector 4.
+- The  **$t_1$**  path leads to 'SPITE 6' and connector 7.
+
+From state 04 (WAIT FOR CALL SET-UP), signals like ADDRESS SIGNAL, BITE 28, CLEAR-FORWARD, BITE 27, and  $t_1$  are monitored:
+
+- ADDRESS SIGNAL** leads to 'FITE 1' and then a decision 'END OF PULSING'. If 'YES', it returns to state 04. If 'NO', it triggers 'START  $t_1$ '.
+- BITE 28** leads to connector 7.
+- CLEAR-FORWARD** leads to 'FITE 22' and connector 4.
+- BITE 27** leads to 'STOP  $t_1$ ' and connector 5.
+- $t_1$**  leads to 'FITE 22', 'SPITE 6', and connector 7.
+
+A separate branch from connector 5 includes 'SPITE 4', 'SPITE 3', and state 05 (CONNECTED). From state 05:
+
+- BITE 22** leads to 'ANSWER (Note 3)'.
+- CLEAR-FORWARD** leads to 'FITE 22' and connector 6.
+- BITE 29** leads to connector 6.

+(Previously "CCITT Recommendation")
+

+
+# FOREWORD
+
+The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+ITU-T Recommendation Q.1151 was revised by the ITU-T Study Group XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993).
+
+---
+
+# NOTES
+
+1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T) was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the IFRB have been replaced by the Radiocommunication Sector.
+
+In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms "CCITT, CCIR or IFRB" or their associated entities such as Plenary Assembly, Secretariat, etc. Future editions of this Recommendation will contain the proper terminology related to the new ITU structure.
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+*(Melbourne 1988, modified at Helsinki, 1993)*
+
+## **1 General**
+
+**1.1** This Recommendation provides information on the services offered in the INMARSAT aeronautical mobile-satellite system and describes the requirements for connection to and interworking with the public networks. Special terminology for this Recommendation is defined in Recommendation Q.1100. Detailed interworking procedures are set out in Recommendation Q.1152.
+
+**1.2** As well as connection to public networks, the aeronautical system is required to be able to interwork with existing specialized private networks. In implementing all interworking cases, regard should be paid to the open systems interconnection referenced model (X.200-Series Recommendations) and to ISDN services and signalling methods (I-Series Recommendations), with a view to achieving uniformity in user procedures and formats and to achieving generally applicable facilities.
+
+**1.3** Within the constraint of the need to operate as economically as possible, the preferred interworking cases are with the ISDN and with those parts of the international telephone network employing common channel signalling. If one of these is not available or accessible at the ISC to which an aeronautical ground earth station (GES) is connected then another signalling system from the Q-Series Recommendations should be used.
+
+**1.4** The use of the ISDN will offer both improvement in quality and more flexibility in service. It will be possible to supply either voice or data over the same network with the ability to change from one to the other under control of the aircraft earth station (AES) terminal.
+
+## **2 Service capabilities**
+
+A general description of the INMARSAT aeronautical system is contained in Appendix I.
+
+### **2.1 Channel capabilities**
+
+**2.1.1** The system provides circuit-mode single channel per carrier (SCPC) channels at a range of information bit rates, including at least the following:
+
+9600 bit/s; 4800 bit/s; 2400 bit/s
+
+Channels for other information bit rates, such as 64 000 bit/s, may be defined in the future.
+
+**2.1.2** The system provides demand assigned forward (ground to air) TDM channels and return (air to ground) random access and (reservation) TDMA channels, at a range of bit rates. Although the following bit rates include housekeeping overheads, they are indicative of the information bit rates provided:
+
+300 bit/s; 600 bit/s; 1200 bit/s; 2400 bit/s; 5250 bit/s.
+
+Channels for other bit rates may be defined in the future.
+
+### 2.2 Bearer capabilities
+
+2.2.1 The following bearer services on SCPC channels, with the following information transfer attributes as defined in Recommendation I.211, may be supported:
+
+- speech (initially at 9.6 kbit/s); transcoding to 64 kbit/s PCM should take place at the GES;
+- circuit mode audio service (initially at 9.6 kbit/s), suitable for voice and other signals occupying the same bandwidth; transcoding to 64 kbit/s PCM should take place at the GES;
+- virtual call bearer service at any of the bit rates defined in 2.1.1, with rate adaptation in the GES to 64 kbit/s using, for example, flow control and flag stuffing;
+- digital data, circuit mode interworking with the ISDN should take place as defined in Recommendation X.30 for data terminals designed to Recommendation X.21, and Recommendation X.32 for data terminals designed to Recommendation X.25.
+
+2.2.2 The following bearer services on TDM, TDMA and RA channels may be supported:
+
+- virtual call bearer service – interworking with the ISDN should take place as defined for interworking between PSPDNs and the ISDN.
+
+### 2.3 Teleservices
+
+Teleservices, when supported, should be in accordance with Recommendation I.212. It is to be observed that not all teleservices of ISDN may be supported with bearer services that can be provided on SCPC or TDM/TDMA channels operating at the available information bit rates.
+
+## 3 Interworking scenarios
+
+Three interworking scenarios can be envisaged for the interface between the MSSC and the fixed networks.
+
+3.1 The first scenario is shown in Figure 1. The MSSC public network interface is to the PSTN only, with all data services, and some voice services, handled via private networks.

+
+# 4 Connection interface requirements
+
+### 4.1 General
+
+This subclause identifies the information that must be available at the interfaces between the AES and the MSSC and between the MSSC and the fixed network, principally for the connection of services identified in 3.
+
+### 4.2 MSSC-network interface
+
+For ISDN connections ISUP should be used for message transfer. For non-ISDN or where ISUP is not available, TUP would be preferred.
+
+If information transport between MSSCs over the fixed network is required, it is suggested that the procedures of the SCCP is used. Detailed interworking procedures are defined in Recommendation Q.1152.
+
+### 4.3 AES-MSSC interface
+
+Prior to and during call initiation the signalling channel functions may be provided by one or more common control channels.
+
+A signalling capability should always be available during conversation in case it is needed for call clearing, call control, or for call management purposes. During a call the signalling channel may be multiplexed with the traffic channel at a lower bit rate so as to conserve radio channel capacity.
+
+The multiplexed signalling channel or TDM/TDMA/RA channels may be used for bearer services such as connectionless data services, or connection oriented data services not requiring the establishment of a traffic channel.
+
+The traffic channel should be used for bearer services such as:
+
+- speech;
+- circuit mode data services;
+- packet mode data services;
+- voice band data services.
+
+### 4.4 Calling procedures air-to-ground
+
+#### 4.4.1 Passenger telephony operation
+
+- a) The equipment for passenger telephony may consist of the following:
+  - the AES;
+  - cabin telephone equipment consisting of a fixed piece of equipment and a handset, which may be “cordless”.
+
+The fixed cabin telephone equipment should be provided with a credit card reader.
+
+- b) When a passenger wants to make a call, the typical sequence of events would be as follows:
+  - i) key-in seat number;
+  - ii) when this is accepted, insert credit card; and
+  - iii) when this is accepted, remove handset and return to seat.
+- c) At the cabin telephone location, if a credit card which corresponds to the recognized card format is inserted into the equipment, the handset shall be released after validation of the check bits and expiry date. In the event that either of these checks fail, the card shall be returned and the handset not released. Upon obtaining the handset the customer returns to his seat and can commence making one or more telephone calls.
+- d) Where telephones and associated credit card readers are located at the passengers' seats, a somewhat different procedure may apply. However, the procedure will still involve reading the credit card, validating the check bits and checking expiry date, before making calls.
+
+#### **4.4.2 Crew telephony operation**
+
+For this case, credit card validation procedures are not required. Crew will have access to special telephone services and networks, according to requirements and procedures developed by the industry. The capabilities will include at least the following:
+
+- a) access to the full public telephone network as for passengers, but without the need for a credit card (billing would be direct to the aircraft operator);
+- b) access to specialized voice services via private networks, with or without address digits;
+- c) ability to preempt an existing (passenger) call if necessary to make AES voice circuit equipment, a satellite channel or GES voice circuit equipment available;
+- d) ability to seize the next available AES voice circuit equipment, but without clearing any calls in progress.
+
+### **4.5 Calling procedures, ground-to-air**
+
+**4.5.1** Selected fixed network users should be able to access aircraft automatically by using the aircraft ID in the address digits. Operator connected access may also be available.
+
+**4.5.2** The numbering plan to enable a PSTN subscriber to call the AES is defined in Recommendation E.215.
+
+## **5 Routing requirements**
+
+### **5.1 Ground originated calls**
+
+The country code 87S should be analysed at all transit centres where the call may either be routed on a circuit containing a satellite link or on a circuit not containing a satellite link. The latter circuit should always be chosen (see Recommendation Q.14).
+
+### **5.2 Aircraft originated calls**
+
+If the signalling system provided between the MSSC and the terrestrial network contains signals which may be used to indicate that one satellite link is included, such signals should be used.
+
+If the signalling system does not contain such signals, the outgoing ISC should avoid forwarding the call on an outgoing circuit which includes a satellite link. If, however, the signalling system employed between the outgoing ISC and the next ISC in the connection contains such signals, the outgoing ISC should insert the required information. The outgoing ISC could base its procedure upon incoming route identification.
+
+# **Appendix I**
+
+## **INMARSAT aeronautical mobile-satellite system description**
+
+(This appendix does not form an integral part of this Recommendation)
+
+## **I.1 Introduction**
+
+The aeronautical satellite system is a mobile communications system intended for use by aircraft in flight. It can provide voice communication services and a range of data communications services.
+
+**I.1.1** The major elements of the aeronautical satellite system as described in this appendix are as follows (see also Figure I.1):
+
+- a) space segment, in particular the satellite communication transponders and associated frequency bands assigned for use by the aeronautical satellite system;
+- b) aircraft earth stations (AES) which are in accordance with the relevant technical requirements, and which interface with the space segment at L-band for communications with ground earth stations, and which interface in the aircraft with data equipment and with crew and passenger voice equipment;
+- c) aeronautical (ground) earth stations (GES) which interface with the space segment (at C-band and L-band) and with the fixed networks, and which are operated in accordance with the relevant technical and operational requirements for communications with AESs; for the “Initial System” GESs will operate to their own essentially independent networks; and
+- d) network coordination stations (NCS) located at designated earth stations, for the purpose of allocating satellite channels, and also for system control and monitoring; NCSs are planned to be introduced at a later stage as part of the “Enhanced System”.
+
+**I.1.2** The aeronautical system is made up of independent communication networks for each satellite ocean area, each network comprising the operational satellite and associated ground control facilities, the AESs and GESs operating within that area, and an NCS. The system design permits GESs to establish communications on a stand-alone basis with AESs without the intervention of the NCS, except in cases of satellite channel shortage.
+
+**I.1.3** Each AES is equipped with a capability to receive a medium rate forward channel transmitted from a GES with a transmission rate of 600 bit/s carrying signalling and data messages in packet form.
+
+**I.1.4** Each AES is equipped to transmit a return carrier in burst mode at a transmission rate of either 600 bit/s or 1200 bit/s controlled by signalling messages received via the forward 600 bit/s channel. This dual capability is required to enable some advantage of the variations in aircraft antenna pattern and in spacecraft receiver sensitivity, which will be encountered during a flight, to be taken.
+
+**I.1.5** AESs may also be equipped with pairs of transmit/receive voice channel equipment and data channel equipment for higher bit rates.
+
+**I.1.6** Each GES is equipped with at least the following data-only transmission capabilities:
+
+- a) one 600 bit/s transmitter for the forward channel;
+- b) four 600 bit/s receivers for the slotted random access channels (this is the minimum to be provided for diversity protection against interference, and burst re-collisions); and
+- c) a receiver for its 600 bit/s forward channel and for the forward channels of each other GES working to the same satellite.
+
+**I.1.7** At the GES owner's option, GESs may also be equipped with:
+
+- a) pairs of transmit/receive voice channel equipment;
+- b) 600 bit/s receiver(s) for a Reservation TDMA channel(s), or 600 bit/s and 1200 bit/s receiver(s) for Reservation TDMA channel(s); and
+- c) additional data channel equipment for the same or higher bit rates.
+
+**I.1.8** The system provides for voice communications by means of the voice channels. Signalling and user data communications is carried on the medium rate (600/1200 bit/s) data channels. This signalling and user data is formatted into fixed length signal units of either 96 bits (12 octets) or 152 bits (19 octets), which are combined as necessary to support various message sizes according to user requirements.
+
+## **I.2 System evolution**
+
+### **I.2.1 General**
+
+**I.2.1.1** The capabilities of the system will evolve with time, due to the progressive development of each of the four major elements identified in I.1.1 above, i.e. space segment, AES, GES and NCS. Although some of the evolutionary steps of one element are inevitably linked with those of other elements, in general the system concept is to allow the individual elements to evolve independently. The pressures which are expected to lead to this evolution include traffic growth, market awareness, new applications and new technology.
+
+**I.2.1.2** The use of narrow-band channels (generally single channel per carrier) and software programmable channel units (modems, etc.) are the principal requirements to achieve the required flexibility, to efficiently utilize a variety of satellite parameters, take advantage of future advances in voice coding technology, allow the aircraft installation to match the services required, and provide a smooth growth path from an initial start-up system through increasing levels of traffic.
+
+### **I.2.2 Space segment evolution**
+
+**I.2.2.1** Within the aeronautical system operational timeframe, it is anticipated that the satellite types of INMARSAT's first generation space segment still in service will comprise MARECS (leased from the European Space Agency) and INTELSAT-V MCS satellites (Maritime Communications Sub-System, leased from the International Telecommunications Satellite Organization). Satellite tracking, telecommand, telemetry and ranging services are included in the leasing arrangements with ESA and INTELSAT, with TT&C stations linked to satellite control centres (SCCs) at Darmstadt (Germany) and Washington DC, respectively. The SCCs are in turn linked to the INMARSAT Operations Control Centre (OCC) in London.
+
+**I.2.2.2** The aeronautical system will also operate with and take advantage of the improved performance of the (second generation) INMARSAT-2 satellites, now on order.
+
+### **I.2.3 AES evolution**
+
+**I.2.3.1** Two types of aircraft antenna are defined, one with a minimum gain of 0 dBi over its coverage area, the other with a minimum gain of 12 dBi over its coverage area. In the initial system, AESs with the 0 dBi antenna are limited to medium rate data services (see I.2.4.2), while AESs with the 12 dBi antenna can obtain multi-channel voice service as well as data services at higher bit rates.
+
+**I.2.3.2** Irrespective of the antenna gain, each AES is required to be equipped with a bit rate switchable data channel unit. The minimum capability is to provide for both 600 bit/s and 1200 bit/s transmission rates (300 bit/s and 600 bit/s information rate, less overheads) and this will suffice for the initial two or three years. Additional, higher bit rates will be needed in the future and these could be provided for in the initial AES design, or be achieved by a software upgrade in a programmable channel unit, or by replacement of a plug-in card.
+
+**I.2.3.3** In operation, the bit rate in use by the AES for data services is determined by signalling from the ground. When commencing service with a given GES, an AES goes through a "log-on" procedure, using the 600 bit/s transmission rate channels assigned for system management (and possibly other) functions. In this log-on procedure, the AES gives its class of equipment provision, and the GES measures the signal level received from the AES if needed, to determine whether a higher bit rate could be supported. From this information the GES assigns working channels for further signalling and data transactions with the AES.
+
+**I.2.3.4** Since the other elements of the system will evolve with time, the AES capabilities have been defined in a way which provides adequate service levels in the start-up phases, but which can take advantage of improved performance in the other elements as they become available, without requiring any significant replacement or upgrade of components. Specifically, the AES is specified with a linear high power amplifier (HPA) with a power output of 40 Watts, and a family of digital channels is defined which are all mutually consistent and compatible.
+
+This makes it feasible to use a single programmable channel unit [using digital signal processor (DSP) microprocessor chips] to implement a suitable selection of channel types from the family, and allow for additional or alternative channel types in the future if required, by software upgrade. The linear characteristic of the HPA permits matching the evolution
+
+of space segment characteristics, providing progressively greater numbers of voice channels with higher performance spacecraft, and also allowing the separation of services in different GESs if required in the future [such as dedicated GESs for air traffic services (ATS)].
+
+**I.2.3.5** It may be anticipated that the service requirements and technology applied to them on aircraft will develop independently of satellite communications. Examples of this type of development are data applications such as for monitoring of equipment health, and the progressive reduction of digital bit rate needed to provide voice service of a given quality. This system makes specific provision for evolution in voice coding, and by adopting a layered approach, along the lines defined in the Open System Interconnection (OSI) model, facilitates its use for as yet unforeseen data applications. In addition, there is ample provision of spare codes in the critical signalling fields, so that if enhancements become necessary they can be implemented by software upgrades.
+
+**I.2.3.6** Although the AES is specified to use a linear HPA, the offset QPSK modulation method is used in the higher bit rate channels in order to make operation with a hard limiting linear (e.g. Class C) HPA feasible. This will permit the development of single-channel AES equipment suitable for general aviation aircraft, when a demand develops.
+
+### **I.2.4 GES evolution**
+
+**I.2.4.1** The aeronautical GES has been defined so it can be produced as a compatible add-on to an existing standard coast earth station in the INMARSAT system. While this type of sharing is not essential, it may enable some economies to be achieved particularly in the start-up phase of the system, and where both services are carried by the same satellite.
+
+**I.2.4.2** As new satellites become available and traffic grows, the data transmission bit rates which can be supported, and need to be supported, will increase. To achieve this, additional data channel units, and/or higher bit rate channel units, will need to be provided at the GESs. The system can operate exclusively with data channel bit rates of 600 bit/s, and this may be sufficient in the initial stage. However, higher bit rates in the return direction (air-to-ground) can be supported even from a 0 dBi antenna, except at edge of coverage with existing (first generation) spacecraft, and will be able to be supported globally with INMARSAT-2 satellites. Thus the provision of higher bit rate channel units by the late 1980s will be appropriate, to provide for growing traffic and to minimize data service message delays. Depending on demand, it may also be appropriate to provide data channel units for interworking with aircraft fitted with 12 dBi antennas. Since all the channels form a compatible family, the possibility exists of using a common hardware unit for all these channels, differing only in software.
+
+**I.2.4.3** To take advantage of evolution in voice coding technology, it may be anticipated that a point will be reached when the voice coding rate and algorithm used in the initial system will be considered inappropriate, at least for new aircraft installations. A decision to adopt new voice coding rate will be practicable, the main requirement being that GESs wishing to interwork with all aircraft will need to operate two sets of channel units and associated voice codecs. As for data, the channel unit hardware could be common, although the voice codecs may be of different designs.
+
+### **I.2.5 NCS evolution**
+
+**I.2.5.1** The function of the NCS is to manage a common pool of satellite voice channels, and to assign them on demand to individual GESs for the duration of one call. In a system with small capacity and multiple GESs the random distribution of traffic across GESs necessitates the provision of a common pool managed by an NCS, for efficiency reasons. When traffic is low in the initial start-up phase, operation with only individual pools of channels at each GES will be satisfactory, but as additional GESs come into service the NCS will become essential.
+
+**I.2.5.2** In the initial system operating without an NCS, communication between GESs is still required to allow aircraft to call or be called via more than one GES. This communication is achieved by using a forward channel from each GES; the channel could be the one also designated for system management functions, or a separate, lower powered channel. In any case the implementation should be arranged so as to facilitate a changeover to a separate interstation link and the provision of an NCS, in the long term.
+
+## I.3 Channel configuration
+
+### I.3.1 General
+
+**I.3.1.1** The basic transmission characteristics of the family of aeronautical system channels are given in Table I.1. The channel bit rates have been selected to facilitate their implementation using a single programmable channel unit and to provide future flexibility. While this may not be practicable now for the highest bit rates in the table, future implementations may be able to take advantage of this structure.

+
+### I.3.2 Channel naming
+
+In order to simplify references to the various channel formats included in the system, each individual format has been assigned a designation as follows (see also Figure I.1):
+
+#### a) *P-Channel*
+
+Packet mode time division multiplex (TDM) channel, used in the forward direction (ground-to-air) to carry signalling and user data; the transmission is continuous from one GES; a P-channel being used for system management functions is designated Psmc, while a P-channel being used for other functions is designated Pd;
+
+#### b) *R-Channel*
+
+Random access (slotted ALOHA) channel, used in the return direction (aircraft-to-ground) to carry some signalling and user data, specifically the initial signals of a transaction, typically request signals; an R-channel being used for system management functions is designated Rsmc, while an R-channel being used for other functions is designated Rd;
+
+#### c) *T-Channel*
+
+Reservation Time Division Multiple Access channel, used in the return direction only; the receiving GES reserves time slots for transmissions requested by AESs, according to message lengths and priority;
+
+#### d) *C-Channel*
+
+Circuit-mode single channel per carrier (SCPC) voice/data channel, used in both forward and return directions; the use of the channel is controlled by assignment and release signalling at the start and end of each call.

+### I.3.3 Forward error correction coding
+
+The majority of channel types use Forward Error Correction (FEC) coding consisting of a convolutional encoder of constraint length  $k = 7$  and an 8-level soft decision Viterbi decoder; the FEC coding rate is either  $3/4$  or  $1/2$ ; the rate  $3/4$  code is derived by puncturing the rate  $1/2$ ,  $k = 7$  convolutional code.
+
+## I.4 Link layer formats and protocols
+
+#### I.4.1 General
+
+All signalling and user data messages are formatted into signal units of length either 96 bits (12 octets) or 152 bits (19 octets). The extended length signal units (19 octets) are only used on the R-channel, whereas the standard length signal units (12 octets) are used on all channels.
+
+More complex messages (including user data) can be carried by a sequence of several signal units. Longer messages generated in a user application will be broken into message fragments in the network layer, compatible with the maximum size, before being presented for transmission via the link layer; the use of these signal units applies to signalling and user data transactions on the sub-band channel of the voice/data channel as well as the P-, R- and T-channels.
+
+### I.4.2 Basic signal unit concepts
+
+**I.4.2.1** A message that can be accommodated in a single signal unit is formatted into a “Lone Signal Unit” (LSU). Longer messages are formatted into more than one signal unit, of which the first is an “Initial Signal Unit” (ISU) followed by one or more “Subsequent Signal Units” (SSU).
+
+**I.4.2.2** Each signal unit includes 16 check bits (the last two octets) for error detection, these being calculated from the preceding octets of the signal unit using the polynomial:  $x^{16} + x^{12} + x^5 + 1$  for generation (see 2.2.7/X.25). The undetected error rate on the sub-band C-channel, under nominal worst case conditions is typically less than one in  $10^{10}$  signal units. The undetected error rate on P- and R-channels is expected to be much less than this.
+
+**I.4.2.3** At the receiver for any channel, the check bits for each received signal unit are calculated, and if there is a mismatch with the received check bits the signal unit is discarded. Recovery from lost and corrupted signal units is handled either by a Reliable Link Service function, or by the relevant signalling logic procedures.
+
+## **I.5 Aircraft earth station management**
+
+**I.5.1** Every GES maintains an up-to-date status table of AESs which have logged into the GES, and has an inter-GES and GES-NCS signalling facility, so that every GES shall be able to set up calls to and from any AES operating to the same satellite, and to manage AESs in the handover process.
+
+**I.5.2** Every AES logs-on to a GES of its choice for entering into the Aeronautical system and logs-out as part of terminating its operation in the system. When an AES requires a change in its log-in GES, accessing satellite or accessing spot beam of a satellite, the AES follows a handover procedure resulting in a smooth transition.
+
+## **I.6 Telephone services**
+
+### **I.6.1 General**
+
+**I.6.1.1** Telephone services are provided using a pair of C-channels (one in each direction) assigned from a pool held by the GES, or by the NCS from a common pool. The function of the NCS is to make C-channel assignments in response to requests from GESs (when the latter runs out of frequencies) on a call-by-call basis.
+
+**I.6.1.2** In the ground-to-air direction, all telephone calls may go to a single answering point on the aircraft, or may be addressed to specific answering points. In the initial system at least, for commercial aircraft, access will be restricted to a very limited number of callers for operational and practical reasons. This restriction will be imposed in the GES, or elsewhere, at the discretion of the GES owner.
+
+**I.6.1.3** In the air-to-ground direction, calls may be made by crew or passengers, with several types of service provided. The primary service capabilities include:
+
+- a) passenger telephony;
+- b) crew general telephony; and
+- c) crew ATC voice.
+
+### **I.6.2 Call set-up/termination for air-to-ground calls**
+
+**I.6.2.1** The basic sequences for air-to-ground telephone call set-up are shown in Figures I.2 to I.5, covering various cases including use of an NCS.
+
+**I.6.2.2** From the point of view of the AES, all the cases are the same, with the AES receiving the called number (and in the case of passenger calls the credit card data) prior to starting the request process. An initial request is sent using the R-channel to the GES where the AES is logged in, and a channel assignment is received on the corresponding P-channel. The communications channel is then set up, tested using signals on the sub-band data channel, and the called party address (plus the credit card number if applicable) is transmitted via the sub-band data channel.
+
+**I.6.2.3** If the air-to-ground call is to the log-on GES (Figure I.2), then all the access request and channel assignment transactions are carried via the R- and P-channels only. However, if the call is to a GES other than the one where the AES logged-on (Figure I.3), then the log-on GES forwards the access request (from the AES) to the called GES (designated "other" GES in Figure I.3) over the interstation link. The called GES allots a channel, if available, from its pool and transmits the channel assignment information over the interstation link. The log-on GES then forwards the information to the AES over the P-channel. The corresponding signalling sequences for air-to-ground call set-up using the NCS are shown in Figures I.4 and I.5, the former representing the case of a call addressed to a log-on GES and the latter showing a call addressed to a GES other than the one where the AES has logged- on.
+
+In the former case (Figure I.4), the log-on GES, on receipt of an access request from the AES, sends a Request for Assignment message over the interstation link to the NCS, whereupon the NCS responds by sending a channel assignment to the requesting GES over the same interstation link. The GES sends this channel assignment to the AES over the P-channel.
+
+In the case of a call addressed to "other" GES, the procedure is similar to the above, with the addition of the log-on GES as an intermediary between the AES and "other" GES. After the call is cleared, the GES to which the channel is assigned by the NCS (i.e the "other" GES), sends the channel release information to the NCS over the interstation link. The transaction is completed by the NCS sending an acknowledgement to the GES.
+
+In the normal case, when the call is ended both parties will replace their handsets (abnormal cases are covered in Figure I-6 and Recommendation Q.1152). The on-hook condition of the telephone in the AES initiates a series of channel release signals on the sub-band C-channel. When one of these is received in the GES, it monitors the carrier to confirm that it stops. If the AES is logged-on to another GES, the channel release signal is sent to the log-on GES via the appropriate interstation link.

The GES then sends a 'C-channel assignment' and 'Test signal units (continuous)' on the 'C, sub-band'. The AES replies with 'Service address and credit card data (if applicable)'. The GES continues with 'C, sub-band' signals. Once the call information is complete, the test signals stop, and the GES sends a 'Call attempt result (address complete)'. The AES responds with '(Continuous)', 'Connect through', 'Service address and credit card data stopped', and an 'Acknowledge'. The GES completes the 'Connect through' phase.

+
+The diagram illustrates the signalling sequence between a Ground Station (GES) and an Air Station (AES) for an air-to-ground call. The sequence starts with the B-party off-hook (Answer) at the GES, followed by a Connect signal. The GES then sends a series of 'C, sub-band' signals to the AES, which responds with an 'Acknowledge'. The GES then sends a 'B-party on-hook (Clearback)' signal, followed by 'Time supervision of 1 to 2 minutes'. The GES then sends a 'Channel release<sup>a)</sup> then carrier off' signal, which the AES acknowledges with 'Channel release<sup>a)</sup> then carrier off'. The GES monitors for carrier off and sends a 'Clearback sequence'. The AES then sends an '(A-Party) On-hook' signal, followed by 'Channel release<sup>a)</sup> then carrier off' and 'Carrier off'. The GES monitors for carrier off again.

+### I.6.3 Channel set-up/termination for ground-to-air calls
+
+**I.6.3.1** The sequences for ground-to-air telephone call set-up are shown in Figures I.7 to I.10 covering various cases, including use of an NCS.
+
+**I.6.3.2** From the viewpoint of the AES, all the cases are similar with the GES sending the call announcement and channel assignment information to the AES over the P-channel. After the channel assignment information is transferred to the AES, the continuity check for proper channel set-up and the eventual channel release functions of the satellite link, are carried out using signals on the sub-band C-channel.
+
+**I.6.3.3** In the case of a call from a log-on GES to an AES (Figure I.7) the only channel used prior to setting up the call is the P-channel. However, if the call is from a GES other than where the AES has logged-on (Figure I.8) the originating GES (“other” GES) sends the call announcement and channel assignment information to the log-on GES over the interstation link. The log-on GES then forwards this information to the AES over the P-channel. The signalling sequences for the cases where the call- originating GES does not have a channel in its allocated pool are shown in Figures I.9 and I.10, the former showing the case of a call originating from a log-on GES and the latter representing a call origination from a GES other than the one to which the AES has logged-on. In both cases the interstation link between the NCS and the call originating GES is used to obtain a channel from the NCS pool. After the call is cleared, the GES from which the call has originated, sends the channel release information to the NCS, which the NCS acknowledges. The procedure for call clearing (illustrated in Figure I.11) is initiated by the terrestrial network sending a clear forward signal, whereupon the GES sends a sequence of channel release signals on the sub-band C-channel. On receipt of one of these, the AES responds with a series of channel release signals, and ceases its carrier. When the GES detects the end of the AES carrier, it returns the channel to the pool.

+
+This sequence diagram illustrates the call set-up between a Ground Station (GES) and an Air Station (AES). The sequence begins with an external 'Call' arriving at the GES. The GES sends a 'Call announcement' (Pd) and a 'C-channel announcement' (Pd) to the AES. The AES responds with 'Test signal units (continuous)'. The GES replies with two 'C, sub-band' messages and also sends its own 'Test signal units (continuous)'. The AES then initiates the 'Call to user terminal' and sends a 'Test signals stopped' message. Finally, the GES sends a 'Connect through' message, leading to 'Ring tone or alerting' at the user terminal.

The GES sends a 'Request for channel assignment' via an Interstation link (ISL) to the NCS. The NCS responds with a 'C-channel assignment'. The GES then sends a 'Call announcement' and 'C-channel assignment' (both marked Pd) to the AES. Continuous 'Test signal units' are then exchanged between the AES and GES on the C, sub-band. Finally, the GES sends a 'C-channel release' (ISL) to the NCS, which acknowledges it with a 'C-channel release ack.' (ISL).

+
+#### I.6.4 Supervisory signalling
+
+**I.6.4.1** After call set-up, all subsequent supervisory functions are normally performed by means of subband signalling on the C-channel.
+
+**I.6.4.2** Continuity checking of the satellite voice channel is done by means of test packets transmitted on the sub-band of the C-channel.
+
+**I.6.4.3** Sub-band signalling on the C-channel is also used for answer/clearing signals, and to provide additional signalling capacity for potential future use in interworking with the terrestrial ISDNs.
+
+**I.6.4.4** Terrestrial network audible tones (ringing, busy, congestion, etc.) are passed to the AES in-band over the voice channel for air-to-ground calls. In the case of ground-to-air calls, the MSSC should return call progress and call failure causes to the terrestrial network by means of appropriate signals, from the signalling system in use. When required (due to the inadequacy of the signalling system in use), the MSSC should also generate audible tones back into the terrestrial network to the calling party.

+# FOREWORD
+
+The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.1210 was prepared by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 17th of October 1995.
+
+---
+
+## NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+# **SUMMARY**
+
+A block of one hundred numbers has been set aside in the Q-Series (Q.1200-Q.1299) for the development of Intelligent Network (IN) Recommendations. Q.1210 is a new Recommendation in the IN-Series that was developed in conjunction with the IN CS-1 refinements to better align the IN CS-1 Recommendations with the overall IN CS-n Recommendation structure.
+
+This Recommendation, the first in the IN Capability Set-1 Series, has been developed to show the organization of the IN CS-1 Recommendations in a meaningful way and to assist users in locating topics of interest. It provides a structural overview of the Q.1200-Series, IN Recommendations, as well as the content of each of the Q.1210-Series, IN CS-1 Recommendations.
+
+Associated standards work is contained in the Q.1200-Series as well as the Q.1210-Series of IN Recommendations.

+# FOREWORD
+
+The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.1218 was revised by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 17th of October 1995.
+
+---
+
+# NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+## **SUMMARY**
+
+This Recommendation defines the intelligent network application protocol for the support of the capabilities required by the CS-1 target services over the CS-1 interfaces (SSF-SCF, SCF-SDF and SCF-SRF) as defined in Recommendation Q.1211. It defines some of the possible protocol stack scenarios, the operations which flow between the entities and the procedures to be followed at each functional entity.
+
+Revisions to this Recommendation provide: details on operations procedures, details on services assumed from underlying protocol layers, extensions to ensure applicability in multiple administration networks, a new SCF-SDF interface for data administration and acquisition based upon the X.500-Series of Recommendations, and detailed error handling procedures. The intent of these revisions is to facilitate consistent multi-vendor implementations in multiple networks.
+
+Associated standardization work is contained in all the Q.1200-Series Recommendations (Intelligent network).

+## **INTERFACE RECOMMENDATION FOR INTELLIGENT NETWORK CS-1**
+
+*(Helsinki, 1993; modified 1995)*
+
+### **0 Introduction**
+
+This Recommendation defines the Intelligent Network Application Protocol, (INAP) required for support of Intelligent Network Capability Set 1. It supports interactions between the following four functional entities (FE's), as defined in the IN functional model:
+
+- Service Switching Function (SSF);
+- Service Control Function (SCF);
+- Specialized Resource Function (SRF);
+- Service Data Function (SDF).
+
+The scope of this Recommendation is the further development of the INAP for both the Integrated Services Digital Network (ISDN) and Public Switched Telecommunications Network (PSTN).
+
+It is intended as a guide to implementors and network operators to ensure interworking between different manufacturers equipment for all the IN CS-1 defined interfaces (SCF-SSF, SCF-SRF and SCF-SDF) and between network operators for the internetwork interface (SCF-SDF).
+
+As this Recommendation is intended for the early introduction of IN in the existing ISDN/PSTN, only simple solutions are assumed for solving the service interaction problems between IN and ISDN/PSTN.
+
+NOTE – More sophisticated solutions for the service interactions between IN and the ISDN/PSTN environment should be studied in the scope of future versions of INAP and the ISDN/PSTN signalling standards.

+## 0.2 Definition methodology
+
+The definition of the protocol can be split into three clauses:
+
+- the definition of the SACF/MACF rules for the protocol (clause 1);
+- the definition of the operations transferred between entities (clause 2);
+- the definition of the actions taken at each entity (clause 3).
+
+The SACF/MACF rules are defined in prose. The operation definitions are in Abstract Syntax Notation 1 (ASN.1, see Recommendations X.208 and X.680), and the actions are defined in terms of state transition diagrams. Further guidance on the actions to be performed on receipt of an operation can be gained from clause 2 and from the relevant information flow in clause 6/Q.1214 (see 0.6 for the relationship between the information flows and the operations).
+
+The INAP is a ROSE user protocol (see Recommendations X.219 and 229). The ROSE protocol is contained within the component sublayer of TCAP (see Recommendations Q.771 to 775) and DSS 1 (see Recommendation Q.932). At
+
+present the ROSE APDU's (Application protocol data units) are conveyed in transaction sublayer messages in SS No. 7 and in the Q.931 REGISTER, FACILITY and call control messages in DSS 1. Other supporting protocols may be added at a later date.
+
+The INAP (as a ROSE user) and the ROSE protocol have been specified using ASN.1. At present, the only standardized way to encode the resulting PDU's is the Basic Encoding Rules (see Recommendation X.209).
+
+### 0.3 Example physical scenarios
+
+The protocol will support any mapping of functional to Physical Entities (PE's). It is the responsibility of network operators and equipment manufacturers to decide how to co-locate FE's to the best possible advantage as this may vary between manufacturers and between network operators. Therefore the protocol is defined assuming maximum distribution (i.e. one PE per FE).
+
+The figures depicted in this subclause show how INAP would be supported in an SS No. 7 network environment. This does not imply that only SS No. 7 may be used as the network protocol to support INAP.
+
+For each physical scenario, the typical SRF control procedures to be applied are shown in 3.1.3.5.
+
+The interface between remotely located SCF and SDF will be INAP using TCAP which in turn, uses the services of the connectionless SCCP and MTP (see Figure 1). The SDF is responsible for any interworking to other protocols to access other types of networks.
+

+
+The diagram illustrates the protocol stack and physical connections for an SCP (Service Control Point) and an SDP (Service Data Point).  
+**SCP Stack:** At the top is the SCF (Service Control Function). Below it is the MACF (Management and Control Function). The MACF connects to two parallel paths. Each path contains a vertical stack of four boxes labeled S, A, C, and F. To the right of the 'A' and 'C' boxes in each path is a box labeled 'ASE(s) (SCF-SSF)'. Below the 'F' box in each path is a box labeled 'TCAP'. Below each 'TCAP' box is a box labeled 'SCCP'. Below each 'SCCP' box is a box labeled 'MTP'. Both 'MTP' boxes connect to a common horizontal line representing the 'SS No. 7 link'. From this link, one path goes left to a box labeled 'To SSP', and the other path goes right to a box labeled 'SS No. 7 network'.  
+**SDP Stack:** At the top is the SDF (Service Data Function). Below it is a vertical stack of four boxes labeled S, A, C, and F. To the right of the 'A' and 'C' boxes is a box labeled 'ASE(s) (SCF-SDF)'. Below the 'F' box is a box labeled 'TCAP'. Below 'TCAP' is a box labeled 'SCCP'. Below 'SCCP' is a box labeled 'MTP'. The 'MTP' box connects to the same 'SS No. 7 link' as the SCP's 'MTP' boxes.

+When TCAP appears in one of the following figures, it shall be understood as representing the TCAP functionalities associated with a single dialogue and transaction (as opposed to a TCAP entity).
+
+If segmentation and re-assembly of INAP messages is required on the SCF-to-SDF interface (and on other interfaces, if needed) due to the length of messages, the segmentation and re-assembly procedure for SCCP connectionless messages, as specified in Q.714, should be used.
+
+A number of example scenarios have been identified for support of the SCF, SSF and SRF functional entities as physical entities. These are illustrated as Figures 2 to 6. Each example is characterized by:
+
+- i) the method to support SCF-SRF relationship; and

+
+## 0.4 INAP protocol architecture
+
+Many of the terms used in this clause are based on the OSI application layer structure as defined in ISO IS-9545.
+
+The INAP protocol architecture can be illustrated as shown in Figure 7.
+
+A physical entity has either single interactions (Case a) or multiple coordinated interactions (Case b) with other physical entities.
+
+In case a, SACF provides a coordination function in using ASE's, which includes the ordering of operations supported by ASE(s), (based on the order of received primitives). The SAO represents the SACF plus a set of ASE's to be used over a single interaction between a pair of PE's.
+
+In Case b, MACF provides a coordinating function among several SAO's, each of which interacts with an SAO in a remote PE.
+
+Each ASE supports one or more operations. Description of each operation is tied with the action of corresponding FE modelling (see Recommendation Q.1214 and clause 3 of this Recommendation). Each operation is specified using the OPERATION macro described in Figure 8 except for the SCF-to-SDF interface, which is described using the CLASS notation.
+
+The use of the application context negotiation mechanism [as defined in the Q.770-Series (Transaction capabilities application part)] allows the two communicating entities to identify exactly what their capabilities are and also what the capabilities required on the interface should be. This should be used to allow evolution through Intelligent Network capability sets.
+
+If the indication of a specific application context is not supported by a pair of communicating FE's, some mechanism to pre-arrange the context must be supported.
+
+![Diagram showing INAP protocol architecture for multiple co-ordinated interactions and single interaction. Both paths show layers: Application process, MACF/SAO (containing SACS and TCAP), SCCP, and MTP. The multiple interactions path has two parallel SACS units.](e69b9188aa2c14ec6b21c83f711fef65_img.jpg)

+#### 0.4.1 INAP signalling congestion control for Signalling System No. 7
+
+The same type of procedure shall apply as defined for ISDN User Part signalling congestion control. The INAP procedures for signalling congestion control shall as far as possible be aligned with the ISDN User Part signalling congestion control procedures as specified (see D.2.11/Q.767), i.e. on receipt of N-PCSTATE indication primitive with the information "signalling point congested" from SCCP, the INAP shall reduce the traffic load (e.g. InitialDP, AnalyzedInformation, or InitiateCallAttempts) into the affected direction in several steps.
+
+The above procedure may only apply to traffic which uses MTP Point Code addressing in the affected direction.
+
+#### 0.5 INAP addressing
+
+SCCP global title and MTP point code addressing [see Q.710-Series (Signalling connection control part) and Q.700-Series (Message transfer part)] ensure that PDU's reach their physical destination (i.e. the correct point code) regardless of which network it is in.
+
+Within a node, it is the choice of the network operator/implementor as to which SSN or SSNs are assigned to INAP.
+
+Regardless of the above, any addressing scheme supported by the SCCP may be used.

+## 0.7 Compatibility mechanisms used for INAP
+
+### 0.7.1 Introduction
+
+This subclause specifies the compatibility mechanisms that shall be used to ensure consistent future versions of INAP.
+
+There are three categories of compatibility:
+
+- *Minor changes to INAP in future standardized versions:*
+
+A minor change can be defined as a change of a functionality which is not essential for the requested IN service. In case it is a modification of an existing function, it is acceptable that the addressed function is executed in either the older or the modified variant. If the change is purely additional, it is acceptable that it is not executed at all and that the peer Application Entity (AE) need not know about the effects of the change. For minor changes, a new AC is not required.
+
+- *Major changes to INAP in future standardized versions:*
+
+A major change can be defined as a change of a functionality which is essential for the requested IN service. In case it is a modification of an existing function, both application entities shall have a shared knowledge about the addressed functional variant. If the change is purely additional, the requested IN service will not be provided if one of the application entities does not support the additional functionality. For major changes, a new AC is required.
+
+- *Network-specific changes to INAP:*
+
+These additions may be of either the major or minor type for a service. No new AC is expected to be defined for this type of change. At the time of definition, the additions would not be expected to be included in identical form in future versions of Recommendations.
+
+## **0.7.2 Definition of INAP compatibility mechanisms**
+
+### **0.7.2.1 Procedures for major additions to INAP**
+
+In order to support the introduction of major functional changes, the protocol allows a synchronization between the two applications with regard to which functionality is to be performed. This synchronization takes place before the new function is invoked in either application entity, in order to avoid complicated fall-back procedures. The solution chosen to achieve such a synchronization is to use the AC negotiation procedures provided in Recommendation Q.773.
+
+### **0.7.2.2 Procedures for minor additions to INAP**
+
+The extension mechanism marker shall be used for future standardized minor additions to INAP. This mechanism implements extensions differently by including an "extensions marker" in the type definition. The extensions are expressed by optional fields that are placed after the marker. When an entity receives unrecognized parameters that occur after the marker, they are ignored (see Recommendation X.680-Series).
+
+### **0.7.2.3 Procedures for inclusion of network specific additions to INAP**
+
+This mechanism is based on the ability to explicitly declare fields of any type via the Macro facility in ASN.1 at the outermost level of a type definition. It works by defining an "ExtensionField" that is placed at the end of the type definition. This extension field is defined as a set of extensions, where an extension can contain any type. Each extension is associated with a value that defines whether the terminating node should ignore the field if unrecognized, or reject the message, similar to the comprehension required mechanism described in the previous subclause. Refer to Recommendation Q.1400 for a definition of this mechanism.
+
+For the SCF-to-SDF interface, the extension mechanisms are defined in 2.2.
+
+## **1 SACF/MACF rules**
+
+### **1.1 Reflection of TCAP-AC**
+
+TCAP Application Context negotiation rules require that the proposed AC, if acceptable, is reflected in the first backwards message.
+
+If the AC is not acceptable, and the TC-User does not wish to continue the dialogue, it may provide an alternate AC to the initiator which can be used to start a new dialogue.
+
+TCAP-AC negotiation applies only to the SCF interfaces.
+
+Refer to the Q.770-Series (Transaction capabilities application part) for a more detailed description of the TCAP AC negotiation mechanism.
+
+### **1.2 Sequential/Parallel execution of operations**
+
+In some cases it may be necessary to distinguish whether operations should be performed sequentially or in parallel (synchronized). Operations which may be synchronized are:
+
+- charging operations may be synchronized with any other operation.
+
+The method of indicating that operations are to be synchronized is to include them in the same message. Where one of the operations identified above must not be executed until some other operation has progressed to some extent or finished, the sending PE (usually SCP) can control this by sending the operations in two separate messages.
+
+This method does not imply that all operations sent in the same message should be executed simultaneously, but simply that where it could make sense to do so (in the situations identified above) the operations should be synchronized.
+
+In case of inconsistency between the above-mentioned generic rules and the FE-specific rules, as specified in clause 3, the FE-specific rules take precedence over the generic rules.
+
+## 2 Abstract syntax of the IN CS-1 Application Protocol
+
+This clause specifies the abstract syntax for the IN CS-1 Application Protocol using Abstract Syntax Notation One (ASN.1), defined in Recommendations X.208 and X.680.
+
+The encoding rules which are applicable to the defined abstract syntax are the basic encoding rules for ASN.1, defined in Recommendation X.209 with the restrictions as described in 4.1.1/Q.773. Additional encodings are cited for parameters used in existing ISUP (Q.763) and DSS 1 (Q.931) Recommendations.
+
+For the ISUP and DSS 1 parameters used in the INAP, only the coding of the parameter value will be coded as defined in ISUP or DSS 1. The DSS 1/ISUP defined parameter identifiers are removed and replaced by the INAP defined parameter identifiers.
+
+The mapping of OPERATION and ERROR to TCAP components is defined in Recommendation Q.773. The class of an operation is not stated explicitly but is specified in the ASN.1 OPERATION MACRO, as follows:
+
+Class 1 – Both RESULT and ERRORS appear in the ASN.1 OPERATION MACRO definition.
+
+Class 2 – Only ERRORS appears in the ASN.1 OPERATION MACRO definition.
+
+Class 3 – Only RESULT appears in the ASN.1 OPERATION MACRO definition.
+
+Class 4 – Neither RESULT nor ERRORS appears in the ASN.1 OPERATION MACRO definition.
+
+These map to the classes 2 through 5, respectively, specified in Recommendations X.219 and Q.932.
+
+The abstract syntax for INAP is composed of several ASN.1 modules describing operations, errors, and associated data types. The values (operation codes and error codes) are defined in a separate module.
+
+The module containing all the type definitions for INAP operations is **IN-CS-1-Operations** and is described in 2.1.1 and 2.2.2.4.1.
+
+The module containing all the type definitions for INAP errors is **IN-CS-1-Errors** and is described in 2.1.2 and 2.2.2.4.1.
+
+The module containing all the type definitions for INAP data types is **IN-CS-1-Data Types** and is described in 2.1.3 and 2.2.2.4.1.
+
+The module containing the operation codes and error codes for INAP is **IN-CS-1-Codes** and is described in 2.1.4 and 2.2.2.4.1.

+- *This operation is used to request the SSF to monitor for a call-related event (e.g. BCSM events such as busy or no answer), then send a notification back to the SCF when the event is detected.*
+- *It is proposed that Event Detection Point (EDP) processing be always initiated by RequestReportBCSMEvent and the EDP may be acknowledged with either an EventReportBCSM or by a DP-specific operations:*
+- *NOTE – The application context should identify whether Request Report BCSM Event ASE and DP Generic BCSM EventReport ASE are being used, or whether Request Report BCSM EventASE, Basic BCP DP ASE, and Advanced BCP DP ASE are being used.*
+- *– For a particular IN, only one of the two alternatives identified by the respective ASEs should be selected (i.e. only one approach should be selected for a given application context).*
+- *– Further study is required to identify the small set of parameters required to be conveyed for EDPs when the Basic BCP DP ASE and Advanced BCP DP ASE are used.*
+- *– For CS2 further study should be given for the feasibility of progressing of one of both alternatives for both TDPs and EDPs.*
+- *– Every EDP must be explicitly armed by the SCF via a RequestReportBCSMEvent operation. No implicit arming of EDPs at the SSF after reception of any operation (different from RequestReportBCSMEvent) from the SCF is allowed.*

+## 2.2 SCF-SDF interface
+
+### 2.2.1 Introduction to the IN X.500 DAP Subset
+
+#### 2.2.1.1 Alignment between the X.500 concepts and the IN
+
+The X.500 Recommendations are used to specify the SCF-SDF interface and the contents of the SDF. Most of the concepts of the X.500-Series are directly used in the IN environment, however some alignments need to be done at the terminology level to ensure that the concepts introduced in the Directory are correctly understood. The purpose of this subclause to provide this alignment. It therefore only concentrates on the terms that are ambiguous in the IN environment.
+
+When looking at the structure of the SCF, the Service Data Management is the part of the SCF responsible for the interactions with the SDF. It can be mapped onto the concept of Directory User Agent (DUA). When a SCF on a behalf of a user wants to setup an association with an SDF, an instance of a DUA is created in the SLPI. It is killed when the association is ended.
+
+The SDF is the entity responsible to answer the database requests. This functional entity can be mapped onto the Directory System Agent (DSA). When an association is setup between an SCF and a SDF, an instance of a DSA is created for the length of the association.
+
+The Directory is a collection of DSAs/SDFs. This set can be used for a specific service or for a variety of services. The notion of Directory is equivalent to the concept of database systems in IN.
+
+The Directory can also be seen as a repository of data. IN services provides various kinds of data access to users. The information is organized into entries. An entry is a collection of information that can be identified (or named). When it represents an object (i.e. contains primary information about an object), it is called an object entry.
+
+Objects are anything which are identifiable (can be named) and which are of interest to hold information on, in the database. A typical example of an object is a user. Objects can be described by several entries. Each individual information that is used to describe an object is an attribute. They are associated to entries.
+
+In the IN environment, the service provider is responsible for the management and the administration of the data contained in an DSA. Therefore the service provider plays the administrator role. He is the administrative authority in X.500 terminology. The service provider enforces the security procedure (authentication and access control).
+
+### 2.2.1.2 Use of a limited subset of X.500
+
+The primary purpose of the X.500-Series Recommendations is to provide a directory service and not the description of the SCF-SDF interface as SG 11 wants to use them. The X.500 functionalities cover more than the functionalities needed for IN CS-1. This subclause tries to indicate which aspects of the Directory Abstract Service should be considered and supported by implementations within the scope of CS-1. It also mentions the attitude to adopt when a not-supported parameter is received. Profiling is used as a means to present the status of the different parameters.
+
+It is important to mention that the number of parameters carried in a message should be minimized, because each of them is associated to a load in the signalling traffic and to some processing time. This is the reason why the parameters are removed unless they are absolutely necessary when they are sent. On reception removed parameters should not be treated but should be understood by the receiving entity. This allows the extensions of the profile in the future according to its actual description in the 1993 edition of the Directory.
+
+For convenience and clarity, this profile is defined using ASN.1 subtyping facilities however these definitions do not form a protocol specification. This simply indicates which parameters an implementation should not send. It does not change the behaviour of the receiving entity which shall still be capable of decoding values conform to the original definition of the Directory Abstract Service. Nevertheless elements that are excluded by subtyping should be ignored.
+
+### 2.2.1.3 Working assumptions
+
+Several assumptions were used to design the Directory Abstract Service profile for IN CS-1. References to the assumptions used are made in 2.2.2.1, they are as follows:
+
+- **Assumption 1:** The version of the Directory Abstract Service used for CS-1 is the 1993 version. The parameters only used for the 1988 version shall be ignored. Functionalities that might be needed in future Capabilities Sets should be at least considered if not supported.
+- **Assumption 2:** Data distribution mechanisms are not considered within CS-1. The reason behind that assumption is that the distribution mechanisms use the SDF-SDF interface that is not part of CS-1. Those mechanisms include the chaining and the broadcasting of requests as well as the referral. Even though they need not to be supported, those indications of the use of such mechanisms should be considered (see assumption 1).
+- **Assumption 3:** Copy mechanisms are not considered within CS-1. Like the data distribution mechanisms, they use the SDF-SDF interface. They imply complex maintenance mechanisms that are not within the scope of CS-1.
+- **Assumption 4:** The operations used for CS-1 do not need to be signed. Since no security requirement was expressed toward the use of signed operations like the definition of an algorithm for the signature, this functionality is not covered within the scope of CS-1.
+
+- **Assumption 5:** The strong authentication mechanisms are not covered by the present profile. Those mechanisms are used for a security system with public keys. Given the present status of the security work, such a functionality is not foreseen for CS-1.
+- **Assumption 6:** The alias entries in IN are just a means to provide an alternative name for an object and therefore should be dereferenced when needed.
+- **Assumption 7:** An SCF-SDF operation cannot be abandoned. If an operation takes too much time, its timer expires and there is no need to abandon it.
+

+
+### 2.2.2.1 Review of X.511 for use in the IN
+
+The profiling of Recommendation X.511 provided thereafter is based upon Recommendation X.511 and the amendments made to it (DAM 2 on contexts, DAM 3 on minor extensions)

+- The **serviceControls** component (see 2.2.2.1.1.3).
+- The **securityParameters** component – The securityParameters component governs the security features associated with a Directory operation (i.e. the signature of an operation). Since the operations are not signed in CS-1 (assumption 4), the securityParameters component should not be present.
+- The **requestor** component provides the name of the originator of a particular operation. This is mainly used for signed requests and as such should not be sent (assumption 4).
+- The **operationProgress**, **referenceType**, **entryOnly**, **exclusions** and **nameResolveOnMaster** components are used when the DUA is acting on a continuation reference from a DSA. Since the distribution mechanisms are not supported (assumption 2), those parameters should not be sent.
+- The **aliasedRDNs** component is present in the 1993 version only for compatibility reasons. It should always be omitted in the 1993 implementations of the Directory (assumption 1).
+- The **criticalExtensions** component is used to indicated to 1988 edition implementations the criticality of a number of extensions which are available in the 1993 versions. Since the 1993 version is used within CS-1 (assumption 1), the component should not be sent. However in the IN context the following extensions should be supported: subentries, modifyRightsRequest, matchedValuesOnly, useAliasOnUpdate, useContexts, selectionOnModify, extendedEntryMods.
+- The **operationContexts** component supplies a set of context assertions which are applied to attribute value assertions and entry information made within the operation. Since the use of contexts is part of the IN requirements, the component is present whenever necessary.
+
+#### 2.2.2.1.1.2 Common results
+
+IN-CommonResults ::= CommonResults (  
+WITH COMPONENTS {  
+securityParameters ABSENT,  
+performer ABSENT,  
+aliasDereferenced})
+
+The status of each component of **CommonResults** parameter is as follows:
+
+- The **securityParameters** component – The operations are not signed therefore this component should not be present.
+- The **performer** component provides the name of the performer of a particular operation. This is mainly used for signed results and as such should not be sent (assumption 4).
+- The **aliasDereferenced** component is set to TRUE when an alias was encountered and dereferenced during the processing of an operation.
+
+#### 2.2.2.1.1.3 Service controls
+
+IN-ServiceControls ::= ServiceControls  
+(WITH COMPONENTS {  
+options ({chainingProhibited, localScope}|  
+({changingProhibited, localScope}|  
+{changingProhibited, localScope, dontDereferenceAliases, subentries}|  
+{chainingProhibited, localScope, subentries}),  
+priority ,  
+timeLimit ABSENT,  
+sizeLimit ABSENT,  
+scopeOfReferral ABSENT,  
+attributeSizeLimit ABSENT})
+
+The status of each component of **ServiceControls** parameter is as follows:
+
+- The **options** component contains an number of indications:
+  - **preferChaining** should be absent because it implies the use of distribution (assumption 2);
+  - **chainingProhibited** and **localScope** should always be set, because chaining is not allowed in CS1 (assumption 2);
+  - **dontUseCopy** and **copyShallDo** refer to copy mechanisms and should not be present (assumption 3);
+  - **dontDereferenceAliases** should only be included when the object of interest is an alias (e.g. to remove an alias);
+  - **subentries** should be set depending on whether the entries or the subentries need to be addressed.
+- The **priority** component is used to specified at which priority the service is to be provided. This parameter could be used to manage congestion in the DSA and may be needed.
+- The **timeLimit** component indicates the maximum elapsed time to fulfil a request. It is redundant with the operation timers of TCAP and therefore is not needed.
+- The **sizeLimit** and the **attributeSizeLimit** sets some size limits on the results either in terms of objects or in terms of attributes. This is useful when requests are expected to be general (the requestor does not know the structure of the DSA), but in the case of IN, this type of limitation does not seem applicable.
+- The **scopeOfReferral** component indicates the scope relevant for a referral. Since referral is not one of the features considered in IN CS1 (assumption 2), the parameter should not be present.
+
+#### 2.2.2.1.1.4 Entry information selection
+
+IN-EntryInformationSelection ::= EntryInformationSelection  
+(WITH COMPONENTS {  
+attributes ,  
+infoTypes (attributeTypesAndValues....),  
+extraAttributes OPTIONAL})
+
+```
+
+contextSelection      OPTIONAL,
+returnContexts        },
+...)
+
+```
+
+The status of each component of **EntryInformationSelection** parameter is as follows:
+
+- The **attributes** component specifies the attributes that should be returned in a retrieval service. The **allUserAttributes** option is kept even though it is advised to service specifiers to avoid its use which generates more traffic than needed. They should use instead the **select** option that precisely name the requested attributes.
+- The **infoTypes** component specifies whether the attribute types and values should be returned or only the types. In IN services are mainly interested in the attribute values that are relevant to the processing of the service. This component should be absent given its default value.
+- The **extraAttributes** component has a similar use as the **attributes** component. The only difference is that the option **allUserAttributes** is replaced by **allOperationalAttributes**.
+- The **contextSelection** component is used to specify which attribute values should be returned of the attributes selected by **attributes** when contexts are used. Therefore this component is of interest for IN specifications.
+- The **returnContexts** component is to request the SDF to return attribute values with their associated context lists. The component can be used for some IN services.
+
+#### 2.2.2.1.1.5 EntryInformation
+
+**IN-EntryInformation ::= EntryInformation**
+
+```
+
+(WITH COMPONENTS {
+    name                PRESENT,
+    fromEntry           (TRUE....),
+    information         (WITH COMPONENTS {
+                        attributeType     ABSENT,
+                        attribute         PRESENT}....) OPTIONAL,
+    incompleteEntry     ,
+    partialNameResolution (FALSE....)},
+...)
+
+```
+
+The status of each component of **EntryInformation** parameter is as follows:
+
+- The **name** component gives the name of the entry returned. It is a mandatory component.
+- The **fromEntry** component indicates if a copy or the entry itself is returned. Since IN CS-1 does not use copy mechanisms (assumption 3), only the default value of this component should be used.
+- The **information** parameter contains the relevant information which is returned. Given the choice made for the **infoTypes** component (see 2.2.2.1.1.4), only the **attribute** option should be used.
+- The **incompleteEntry** parameter indicates when the returned result is not complete due to some access rights limitations for example. It is necessary to support such a parameter.
+- The **partialNameResolution** component indicates whether the name resolution was partially or totally completed. This component does not correspond to any IN requirements and is not included.
+
+#### 2.2.2.1.1.6 Optionally-signed parameters
+
+**UNSIGNED {Type} ::= OPTIONALLY-SIGNED {Type}**
+
+```
+
+(WITH COMPONENTS {
+    unsigned            PRESENT,
+    signed              ABSENT})
+
+```
+
+The operations are not signed for CS-1 (assumption 4). This means that only the unsigned option should be used.
+
+### 2.2.2.1.2 Bind operation
+
+```
+in-DirectoryBind OPERATION ::= {  
+    ARGUMENT      IN-DirectoryBindArgument  
+    RESULT        IN-DirectoryBindResult  
+    ERRORS        {in-DirectoryBindError}
+```
+
+The **DirectoryBind** and **DirectoryUnbind** operations are used at the beginning and end of a particular period of accessing the Directory.
+
+#### 2.2.2.1.2.1 Bind arguments and results
+
+```
+IN-DirectoryBindArgument ::= DirectoryBindArgument  
+(WITH COMPONENTS {  
+    credentials     (IN-Credentials) OPTIONAL,  
+    versions        })
+```
+
+```
+IN-Credentials ::= Credentials  
+(WITH COMPONENTS {  
+    simple          ,  
+    strong          ABSENT,  
+    externalProcedure })
+```
+
+```
+IN-DirectoryBindResult ::= IN-DirectoryBindArgument
+```
+
+The status of each parameter of **DirectoryBindArgument** is as follows:
+
+- The **credentials** parameter is used to establish the identity of the user. It is necessary for services that requires authentication. However, the **strong** credentials should not be used because they correspond to the use of a public key system (assumption 5).
+- The **versions** parameter identifies the version of the **DirectoryService** which is to be used.
+
+The same considerations apply to the **DirectoryBindResult**.
+
+#### 2.2.2.1.2.2 Bind errors
+
+```
+in-DirectoryBindError ERROR ::= {  
+    PARAMETER IN-DirectoryBindErrorParameter}
+```
+
+```
+IN-DirectoryBindErrorParameter ::= DirectoryBindErrorParameter  
+(WITH COMPONENTS {  
+    versions          ,  
+    error             (WITH COMPONENTS {  
+        securityError     (SecurityProblem (1/2/7...)),  
+        serviceError      (ServiceProblem (2))})})
+```
+
+The **DirectoryBindError** remains as defined in the **Directory** Abstract Service. In reception, all the possible errors should be supported to understand a Bind error.
+
+### 2.2.2.1.3 Search operation
+
+```
+in-Search OPERATION ::= {  
+    ARGUMENT      IN-SearchArgument  
+    RESULT        IN-SearchResult  
+    ERRORS        {in-NameError | in-ServiceError | in-SecurityError | attributeError}  
+    CODE          id-opcode-in-search}
+```
+
+The search operation is used to search a portion of the DIT for entries of interest.
+
+#### 2.2.2.1.3.1 Search arguments and errors
+
+```
+IN-SearchArgument ::= UNSIGNED {SearchArgument  
+(WITH COMPONENTS {  
+    baseObject        PRESENT,  
+    subset            ,  
+    filter            ,  
+    searchAliases     (TRUE...),  
+    selection         (IN-EntryInformationSelection...),  
+    pagedResults      ABSENT,
+```
+
+```
+
+    matchedValuesOnly      ,
+    extendedFilter         ABSENT,
+    checkOverspecified   },
+  ...)}
+
+```
+
+The status of each parameter of **SearchArgument** is as follows:
+
+- The **baseObject** parameter identifies the object entry where the search operation should take place. It is a mandatory parameter.
+- The **subset** parameter indicates which part of the DIT should be involved in the search operation. This parameter is needed even though the use of the wholeSubtree should be avoided to prevent the operation timer to expire.
+- The **filter** parameter is used to eliminate entries from the search space. However the **extendedFilter** parameter was added in the 1993 version of the Directory for compatibility reasons and should therefore not be sent. Only the **filter** parameter should be sent.
+- The **searchAliases** parameter indicates whether the aliases encountered in the search space (except the base object) should be considered. Since in IN aliases are always dereferenced when searching, this parameter should be used only with its default value.
+- The **selection** parameter indicates what information from the entries, e.g. types and values, is requested (see 2.2.2.1.1.4).
+- The **pagedResults** parameter is used to request a page by page result. The **pagedResults** parameter is used to present the results of a search operation in a page format. This type of information is not needed in CS-1 since the SCF treats the results.
+- The **matchedValuesOnly** is a facility used to return only the values that fulfil the filter if any. This might be needed for IN CS-1.
+- The **checkOverspecified** parameter is used to request the SDF to return an **overspecFilter** item in the Search result when appropriate. The IN services might need an **overspecFilter** item and therefore this parameter should be included.
+
+Concerning errors, the **abandoned** and the **referral** errors are not supported.
+
+### 2.2.2.1.3.2 Search results
+
+```
+
+IN-SearchResult ::= UNSIGNED {SearchResult
+  (WITH COMPONENTS {
+    searchInfo      (WITH COMPONENTS {
+      name          ,
+      entries       (WITH COMPONENT (IN-EntryInformation...)...),
+      partialOutcomeQualifier (PartialOutcomeQualifier

+          ...) ...)},
+      ...),
+    uncorrelatedSearchInfo ABSENT},
+  ...)}
+
+```
+
+The status of each parameter of **SearchResult** is as follows:
+
+- The **name** parameter indicates the name of the returned entries if different from the name of the **baseObject** name. It is needed when the search operation has entries other than the base object as a result.
+- The **entries** parameter contains the entries that satisfy the filter (see 2.2.2.1.1.5).
+
+- The **partialOutcomeQualifier** parameter is present when the search operation was not fully completed. It contains information on the reasons why the search operation was not finished and on where the operation was stopped:
+  - The **limitProblem** parameter indicates which type of limit was reached (administrative). It is necessary to carry such indications.
+  - The **unexplored** parameter indicates where the search operation was stopped and gives indications about the state of the operation (object considered and progress indication). If the operation is to be resent, such a parameter is needed. This is equivalent to a referral and as such should be absent (assumption 2).
+  - The **unavailableCriticalExtensions** parameter indicates that some critical extensions were not available.
+  - The **unknownErrors** parameter corresponds to the reception of unknown errors from other SDF. It implies the use of a chaining mechanism that is not available in CS-1 (assumption 2) and is not used.
+  - The **queryReference** parameter is used when paged results were requested and therefore is not needed.
+  - The **overspecFilter** parameter is used when the returned Search result is empty as a consequence of over-specified filtering. The filter returned corresponds to a part of the initial filter for which some entries are still available. This functionalities could be used for IN services.
+- The **uncorrelatedSearchInfo** contains signed results that could not be unsigned. Since the operations are not signed in IN CS-1, this parameter should not be used.
+
+#### 2.2.2.1.4 AddEntry operation
+
+```
+in-AddEntry OPERATION ::= {
+  ARGUMENT  IN-AddEntryArgument
+  RESULT    AddEntryResult
+  ERRORS    {nameError | in-ServiceError | in-SecurityError | attributeError |
+             in-UpdateError}
+  CODE      id-opcode-in-addEntry}
+```
+
+The addEntry operation is used to add a leaf entry to the DIT.
+
+##### 2.2.2.1.4.1 AddEntry arguments, results and errors
+
+```
+IN-AddEntryArgument ::= UNSIGNED {AddEntryArgument
+  (WITH COMPONENTS {
+    object      PRESENT,
+    entry       PRESENT,
+    targetSystem ABSENT})}
+```
+
+The status of each parameter of **AddEntryArgument** is as follows:
+
+- The **object** parameter identifies the entry to be added. It is a mandatory parameter.
+- The **entry** parameter describes the entry to be added. It is also a mandatory parameter.
+- The **targetSystem** parameter contains the name of the SDF where the entry was added. When no distribution is considered (assumption 2), the SDF is the same as the one where the operation was sent. The parameter is therefore unnecessary.
+
+Concerning errors, the **referral** error is not supported.
+
+#### 2.2.2.1.5 RemoveEntry operation
+
+```
+in-RemoveEntry OPERATION ::= {
+  ARGUMENT  IN-RemoveEntryArgument
+  RESULT    RemoveEntryResult
+  ERRORS    {nameError | in-ServiceError | in-SecurityError | in-UpdateError}
+  CODE      id-opcode-in-removeEntry}
+```
+
+The `removeEntry` operation is used to remove a leaf entry from the DIT.
+
+#### 2.2.2.1.5.1 RemoveEntry arguments, results and errors
+
+**IN-RemoveEntryArgument ::= UNSIGNED {RemoveEntryArgument}**
+
+The parameters are only the name of the object to be deleted. It is mandatory. The argument of the operation should be kept as it is described in the Directory.
+
+Concerning errors, the **referral** error is not supported.
+
+#### 2.2.2.1.6 ModifyEntry operation
+
+**in-ModifyEntry OPERATION ::= {**  
+    **ARGUMENT           IN-ModifyEntryArgument**  
+    **RESULT           IN-ModifyEntryResult**  
+    **ERRORS           {nameError | in-ServiceError | in-SecurityError | attributeError |**  
+    **in-UpdateError}**  
+    **CODE             id-opcode-in-modifyEntry}**
+
+The `modifyEntry` operation is used to perform a series of modifications to a single entry.
+
+##### 2.2.2.1.6.1 ModifyEntry arguments and errors
+
+**IN-ModifyEntryArgument ::= UNSIGNED {ModifyEntryArgument**  
+    **(WITH COMPONENTS {**  
+        **object           PRESENT,**  
+        **changes          PRESENT,**  
+        **selection        (IN-EntryInformationSelection)})}**
+
+The parameters are the name of the object to be modified, the list of changes and the **selection** parameter that specifies some attributes and values to be returned. The first two are mandatory and the third one corresponds to 2.2.2.1.1.4. Since all the changes available in the **changes** parameter are useful for IN CS-1, the argument of the operation should be kept as it is described in the Directory except the selection parameter.
+
+Concerning errors, the **referral** error is not supported.
+
+##### 2.2.2.1.6.2 ModifyEntry results
+
+**IN-ModifyEntryResult ::= ModifyEntryResult**  
+    **(WITH COMPONENTS {**  
+        **null                   ,**  
+        **information          UNSIGNED {Information**  
+            **(WITH COMPONENTS {**  
+                **entry        (IN-EntryInformation)})}**
+
+If no information was to be retrieved with the `modifyEntry` operation, the **null** result is returned. Otherwise the information is to be returned in the **entry** component of the **information** result. For IN CS-1 this component is specified in 2.2.2.1.15.
+
+#### 2.2.2.1.7 Errors
+
+The precedence rule defined in the Directory should apply.
+
+The **abandoned**, **abandonFailed** and **referral** errors are not considered because not supported by CS-1 (assumption 1 and assumption 7).
+
+##### 2.2.2.1.7.1 Attribute error
+
+All the attribute problems cited in the **attributeError** can be used in CS-1 and therefore this error should not be modified and directly taken from the Directory.
+
+##### 2.2.2.1.7.2 Name error
+
+All the naming problems cited in the **nameError** can be used in CS-1 and therefore this error should be modified and directly taken from the Directory.
+
+### 2.2.2.1.7.3 Security Error
+
+```
+in-SecurityError ERROR ::= {  
+    PARAMETER IN-SecurityErrorParameter

+  
+IN-SecurityErrorParameter ::= SecurityErrorParameter  
+(WITH COMPONENTS {  
+    problem (SecurityProblem (1 | 2 | 3 | 6))})
+```
+
+The **securityError** reports a security problem that was encountered during the execution of an operation.
+
+It contains only the **problem** parameter that indicates which type of problem was met. Among the possible problems, the **invalidSignature** and **protectionRequired** ones should not be sent, because they are used in conjunction with signed operations (assumption 4).
+
+### 2.2.2.1.7.4 Service error

+IN-ServiceErrorParameter ::= ServiceErrorParameter  
+(WITH COMPONENTS {  
+    problem (ServiceProblem (1 | 2 | 3 | 5 | 10 | 8 | 9 | 12))})
+```
+
+The **serviceError** reports a problem related to the provision of the service.
+
+It contains only the **problem** parameter that indicates which type of problem was encountered. Among the possible problems, several should not be sent because they are linked to distributed operation (assumption 2), to the incompatibility of versions (assumption 1) and to the use of paged results. That are the **chainingRequired**, **invalidReference**, **timeLimitExceeded**, **outOfScope** and **invalidQueryReference** problems.
+
+### 2.2.2.1.7.5 Update error
+
+```
+in-UpdateError ERROR ::= {

+  
+IN-UpdateErrorParameter ::= UpdateErrorParameter  
+(WITH COMPONENTS {  
+    problem (UpdateProblem (1 | 2 | 3 | 4 | 5 | 7))})
+```
+
+The **UpdateError** reports problems related to attempts to add, delete, or modify information in the DIB. It contains only the **problem** parameter that indicates which type of problem was encountered. Among the possible problems, the **affectsMultipleDSAs** problem should not be sent because it is linked to distributed operation (assumption 2).
+
+## 2.2.2.2 Directory Access Protocol Subset
+
+### 2.2.2.2.1 Protocol overview
+
+#### 2.2.2.2.1.1 Remote Operations – Specification and SS No. 7 realization
+
+ITU-T Rec. X.880 | ISO/IEC 13712-1 defines several information object classes that are useful in the specification of ROS-based application protocols such as the various Directory protocols defined in this Directory Specification. A number of these classes are used in this and subsequent subclauses. The specification techniques provided in ITU-T Rec. X.880 | ISO/IEC 13712-1 are used to define a generic protocol between objects. When realized as an SS No. 7 application layer protocol, the concepts of ITU-T Rec. X.880 | ISO/IEC 13712-1 are mapped to SS No. 7 concepts in Recommendation Q.775. The SS No. 7 application layer protocol defined in this Recommendation, is a protocol to provide communication between a pair of application processes. In the SS No. 7 environment this is represented as communication between a pair of application-entities (AEs) using the Transaction Capabilities. The function of an AE is
+
+provided by a set of application-service-elements (ASEs). The interaction between AEs is described in terms of their use of the services provided by the ASEs. All the services provided by the Directory ASEs are contained in a single AE. The Component Handler (CHA) of the Transaction Capabilities (TC) supports the request/reply paradigm of the operation. The Directory ASEs provide the mapping function of the abstract-syntax notation of the directory operation packages onto the services provided by TC. The Dialogue handler (DHA) of the TC supports the establishment and release of an application – association called "dialogue" between a pair of AEs. Dialogues between a DUA and a DSA may be established only by the DUA.
+
+#### 2.2.2.2.1.2 Directory ROS-Objects and Contracts
+
+ITU-T Rec. X.511 | ISO/IEC 9594-3 defines the abstract service between a DUA and the Directory which provides an access point to support a user accessing Directory services. Subclause 2.2.2 defines the sub-set of this abstract service used in the context of Intelligent Networks.
+
+The **dua** class of ROS-object describes a DUA, being an instance of this class, as the initiator of the contract **dapContract**. This contract is referred to in these Directory Specifications as the Directory Abstract Service. It is specified as a ROS-based information object in 2.2.2.2.1.3.
+
+```
+dua      ROS-OBJECT-CLASS ::= {
+    INITIATES    {dapContract}
+    ID           id-rosObject-dua}
+```
+
+The **directory** class of ROS-object describes the provider of the Directory Abstract Service. This provider is the responder of the **dapContract**.
+
+```
+directory  ROS-OBJECT-CLASS ::= {
+    RESPONDS     {dapContract}
+    ID           id-rosObject-directory}
+```
+
+The Directory is further modeled as being represented to a DUA by a DSA which support the particular access point concerned. In the context of Intelligent Networks, each DSA is potentially an access point to the Directory.
+
+The **directory** object is manifested as a set of DSAs (each of which resides in an SDF). Each DSA comprising the **directory** is an instance of the **dap-dsa** class. A **dap-dsa** object assumes the role of responder in the **dapContract**.
+
+```
+dap-dsa    ROS-OBJECT-CLASS ::= {
+    RESPONDS     {dapContract}
+    ID           id-rosObject-dapDSA}
+```
+
+Future versions of this Recommendation will enable DSAs to interact with one another to achieve various objectives.
+
+#### 2.2.2.2.1.3 DAP Contract and Packages
+
+The **dapContract** is defined as an information object of class CONTRACT.
+
+```
+dapContract  CONTRACT ::= {
+    CONNECTION           dapConnectionPackage
+    INITIATOR CONSUMER OF {searchPackage | modifyPackage}
+    ID                   id-contract-dap}
+```
+
+When a DUA and DSA from different IN physical entities, this association contract shall be realized as an SS No. 7 application layer protocol, referred to as the IN Directory Access Protocol (DAP). The definition of this protocol in terms of an SS No. 7 application context is provided in 7.2.
+
+The **dapContract** is composed of a **connection package**, **dapConnectionPackage**, and two operation packages, **searchPackage** and **modifyPackage**. The **connection package**, **dapConnectionPackage**, is defined as an information object of class CONNECTION-PACKAGE. The bind and unbind operations of this connection package, **directoryBind** and **directoryUnbind**, are defined in ITU-T Rec. X.511 | ISO/IEC 9594-3.
+
+```
+dapConnectionPackage  CONNECTION-PACKAGE ::= {
+    BIND               directoryBind
+    UNBIND             directoryUnbind
+    ID                 id-package-dapConnection}
+```
+
+The operation packages, **searchPackage** and **modifyPackage**, are defined as information objects of class OPERATION-PACKAGE. The operations of these operation packages are defined in ITU-T Rec. X.511 | ISO/IEC 9594-3. ITU-T Rec. X.511 | ISO/IEC 9594-3 defines additional operations for supporting access to the Directory. Such operations are not used in the context of Intelligent Networks.
+
+```
+searchPackage      OPERATION-PACKAGE ::= {  
+    CONSUMER INVOKES          {search}  
+    ID                          id-package-search}  
+modifyPackage      OPERATION-PACKAGE ::= {  
+    CONSUMER INVOKES          {addEntry | removeEntry | modifyEntry}  
+    ID                          id-package-modify}
+```
+
+NOTE – These packages, when realized as ASEs, are used for the construction of application contexts defined in this Specification. They are not intended to allow for claims of conformance to individual, or other combinations of, ASEs.
+
+Since the DUA is the initiator of the **dapContract**, it assumes the role of consumer of the operation packages of the contract. This means that only the DUA can invoke operations in this contract and its SS No. 7 realization.
+
+#### 2.2.2.2.1.4 Use of underlying services
+
+The DAP protocol makes use of underlying services as described below.
+
+##### 2.2.2.2.1.4.1 Use of component handling services
+
+The Directory ASEs are users of the TC component handling services except for the TC-L-REJECT and TC-L-CANCEL services which are used by the application-process. Receipt of a TC-L-REJECT-Ind or TC-L-CANCEL-Ind, leads the application-process to abandon the dialogue (i.e. it issues a TC-U-ABORT-Request primitive).
+
+The TC-U-CANCEL service is never used.
+
+##### 2.2.2.2.1.4.2 Use of dialogue handling services
+
+Dialogue handling services are used to support the DirectoryBind and DirectoryUnbind operations and to trigger the sending of the APDUs associated with the operations involved in the Directory packages.
+
+Component grouping is performed under the control of the application-process through an appropriate usage of the TC-BEGIN and TC-CONTINUE service.
+
+The TC-END service is solely used to support the unbind procedure (i.e. it is never used to trigger the sending of components).
+
+On receipt of an empty TC-CONTINUE.req primitive, the SDF should ignore the primitive.
+
+On receipt of a TC-END.req with a database request, the SDF should not perform the database request and consider the requested TC-END service as an unbind procedure. The dialogue is then terminated (see 2.2.2.2.3.1.2).
+
+On receipt of a TC-U-REJECT.ind in the SDF, this primitive should be ignored.
+
+On receipt of a TC-R-REJECT.ind in the SDF, the dialogue should be released with a TC-U-ABORT.req.
+
+If reject situations are detected in the SDF, a TC-U-REJECT.req should be sent followed by a TC-CONTINUE.req.
+
+The pre-arranged termination procedure is never used.
+
+The application-process is the sole user of the TC-P-ABORT service and TC-NOTICE service.
+
+The receipt of a TC-U-ABORT-Ind or TC-P-ABORT-Ind on a dialogue terminates all request processing. It is the application-process responsibility to confirm if requested modifications occurred.
+
+It is an application-process responsibility to provide in the TC-BEGIN.req primitive a destination address which can be used by the underlying SCCP to route the message to the proper SDF.
+
+### 2.2.2.2.2 Directory protocol abstract syntax
+
+#### 2.2.2.2.2.1 Abstract syntaxes
+
+This version of the Directory Access Protocol requires the support of three abstract syntaxes:
+
+- a) the abstract-syntax of TC dialogue control protocol data units, **dialogue-abstract-syntax**, which is needed to establish the dialogues between the SCFs and the SDFs and is specified in Recommendation Q.773;
+- b) the abstract-syntax for conveying the protocol data units for invoking **directoryBind** and **directoryUnbind** operations and reporting their outcome;
+- c) the abstract-syntax for conveying the protocol data units for invoking the operations involved in the operation packages specified in 2.2.2.2.1.3 and reporting their outcome.
+
+The ASN.1 type from which the values of the second abstract syntax are derived is specified using the parameterized types, **Bind {}** and **Unbind {}** which are defined in Recommendation X.880.
+
+The ASN.1 type from which the values of the last abstract syntax are derived is specified using the parameterized types **TCAPMessage {}** defined in Recommendation Q.773.
+
+All these abstract syntaxes shall (as a minimum) be encoded according to the Basic ASN.1 encoding rules with the restrictions listed in Recommendation Q.773.
+
+##### 2.2.2.2.2.1.1 DAP Abstract Syntax
+
+The Directory ASEs that realize the operation packages specified in 2.2.2.2.1.3 share a single abstract syntax, **directoryOperationsAbstractSyntax**. This is specified as an information object of the class ABSTRACT-SYNTAX.
+
+```
+inDirectoryOperationsAbstractSyntax      ABSTRACT-SYNTAX ::= {  
+    BasicDAP-PDUs  
+    IDENTIFIED BY                          id-as-directoryOperationsAS}  
+  
+BasicDAP-PDUs ::= TCAPMessage {{DAP-Invokable},{DAP-Returnable}}  
+  
+DAP-Invokable      OPERATION      ::= {search | addEntry | removeEntry | modifyEntry}  
+  
+DAP-Returnable     OPERATION      ::= {search | addEntry | removeEntry | modifyEntry}
+```
+
+The realization of the connection package specified in 2.2.2.2.1.3 uses a separate abstract syntax, **directoryBindingAbstractSyntax**. This is specified as an information object of the class ABSTRACT-SYNTAX.
+
+```
+InDirectoryBindingAbstractSyntax      ABSTRACT-SYNTAX ::= {  
+    DAPBinding-PDUs  
+    IDENTIFIED BY                          id-as-directoryBindingAS}  
+  
+DAPBinding-PDUs ::= CHOICE {  
+    bind      Bind {directoryBind},  
+    unbind    Unbind {directoryUnbind}}
+```
+
+#### 2.2.2.2.2.2 Directory application contexts
+
+##### 2.2.2.2.2.2.1 Directory Access Application Context
+
+The **dapContract** is realized as the **iNdirectoryAccessAC**. This application context is specified as an information object of the class APPLICATION-CONTEXT.
+
+```
+iNdirectoryAccessAC      APPLICATION-CONTEXT ::= {  
+    CONTRACT      dapContract  
+    DIALOGUE MODE structured  
+    TERMINATION basic  
+    ABSTRACT SYNTAXES {dialogue-abstract-syntax |  
+        inDirectoryOperationsAbstractSyntax |  
+        inDirectoryBindingAbstractSyntax }  
+    APPLICATION CONTEXT NAME id-ac-directoryAccessAC}
+```
+
+### **2.2.2.2.2.3 Operation Codes**
+
+The operations involved in the packages defined in this Recommendation are specified in Recommendation X.519 where the assigned operation codes are imported from Recommendation X.519.
+
+### **2.2.2.2.2.4 Error Codes**
+
+The errors involved in the packages defined in this Recommendation are specified in Recommendation X.519 where the assigned error codes are imported from Recommendation X.519.
+
+### **2.2.2.2.2.5 Versions and the rules for extensibility**
+
+The Directory may be distributed and more than two Directory Application Entities may interoperate to service a request. The Directory AEs may be implemented conforming to different editions of the Directory specification of the Directory service which may or may not be represented by different protocol version numbers. The version number is negotiated to the highest common version number between two directly binding Directory AEs.
+
+#### **2.2.2.2.2.5.1 Version negotiation**
+
+When accepting an association, i.e. binding, utilizing the DAP, the version negotiated shall only affect the point-to-point aspects of the protocol exchanged between the DUA and the DSA to which it is connected. Subsequent requests or responses on the association shall not be constrained by the version negotiated.
+
+NOTE – There are no point-to-point aspects of the DAP that are currently indicated by different protocol versions.
+
+#### **2.2.2.2.2.5.2 DUA side**
+
+##### **2.2.2.2.2.5.2.1 Request and response processing at the DUA side**
+
+The DUA may initiate requests using the highest edition of the specification of that request it supports. If one or more elements of the request are critical, it shall indicate the extension number(s) in the critical Extensions parameter.
+
+NOTE 1 – If the information, the extension replaced in a CHOICE, ENUMERATED or INTEGER (used as ENUMERATED) type would be essential for proper operation in a DSA implemented according to an earlier edition of this Specification, it is recommended that the extension be marked critical.
+
+When processing a response, a DUA shall:
+
+- a) ignore all unknown bit name assignments within a bit string; and
+- b) ignore all unknown named numbers in an ENUMERATED type or INTEGER type that is being used in the enumerated style, provided the number occurs as an optional element of a SET or SEQUENCE; and
+- c) ignore all unknown elements in SETs, at the end of SEQUENCES, or in CHOICES where the CHOICE is itself an optional element of a SET or SEQUENCE.
+
+NOTE 2 – Implementations may as a local option ignore certain additional elements in a Directory PDU. In particular, some unknown named numbers and unknown CHOICES in mandatory elements of SETs and SEQUENCES can be ignored without invalidating the operation. The identification of such elements is for further study.
+
+- d) not consider the receipt of unknown attribute types and attribute values as a protocol violation; and
+- e) optionally report the unknown attribute types and attribute values to the user.
+
+##### **2.2.2.2.2.5.2.2 Extensibility rules for error handling at the DUA side**
+
+When processing a known error type with unknown indicated problems and parameters, a DUA shall:
+
+- a) not consider the receipt of unknown indicated problems and parameters as a protocol violation (i.e. it shall not issue a TC-U-REJECT or abort the dialogue); and
+- b) optionally report the additional error information to the user.
+
+When processing an unknown error type, a DUA shall:
+
+- a) not consider the receipt of unknown error type as a protocol violation (i.e. it shall not issue a TC-U-REJECT or abort the application association); and
+- b) optionally report the error to the user.
+
+### 2.2.2.2.2.5.3 Request processing at the DSA side
+
+If any DSA performing an operation detects an element **criticalExtensions** whose semantic is unknown, it shall return an **unavailableCriticalExtension** indication as a **serviceError**.
+
+NOTE 1 – If a **criticalExtensions** string with one or more zero values is received, this indicates either that the extensions corresponding to the values are not present or are not critical. The presence of a zero value in a **criticalExtensions** string shall not be inferred as either the presence or absence of the corresponding extension in the APDU.
+
+Otherwise, when processing a request from a DUA, a DSA shall:
+
+- a) ignore all unknown bit name assignments within a bit string; and
+- b) ignore all unknown named numbers in an **ENUMERATED** type or **INTEGER** type that is being used in the enumerated style, provided the number occurs as an optional element of a **SET** or **SEQUENCE**; and
+- c) ignore all unknown elements in **SETs**, at the end of **SEQUENCEs**, or in **CHOICEs** where the **CHOICE** is itself an optional element of a **SET** or **SEQUENCE**.
+
+NOTE 2 – Implementations may as a local option ignore certain additional elements in a Directory PDU. In particular, some unknown named numbers and unknown **CHOICEs** in mandatory elements of **SETs** and **SEQUENCEs** can be ignored without invalidating the operation. The identification of such elements is for further study.

+
+#### **2.2.2.3 X.501 profile**
+
+The Recommendation X.501 provides a generic information model that is needed to support the service provided by the Directory. In the context of IN, the generic information model should conform to the part of the Recommendation going from clauses 1 to 7 of the Recommendation X.501. However certain aspects of this Recommendation need not to be supported. This includes the DIT content rules whose use is a local matter.
+
+Some other points are outside the scope of this Recommendation. This concerns the distributed procedures, the replications procedures and other items associated with capabilities not covered by IN CS-1. Therefore the following parts of Rec. X.501 are not applicable:
+
+- Subclause 3.3 Distributed operation definitions;
+- Subclause 3.4 Replication definitions;
+- last paragraph of 6.3.2;
+- paragraphs f), h) and i) in 16.2.3;
+- paragraph a) in 16.2.4. The compare operation is not used, the search operation is used instead. Therefore the FilterMatch permission replaces the Compare permission.
+
+In this subclause when it is referred to Recommendation X.501, it refers to the modified version of the Recommendation X.501 including the amendments made to it (DAM2 on contexts and DAM3 on minor extensions).
+
+#### **2.2.2.4 ASN.1 Profile of the Directory Abstract Service for the IN CS-1**

+
+#### 3.1 Definition of procedures and entities
+
+##### 3.1.1 SSF application entity procedures
+
+###### 3.1.1.1 General
+
+This clause provides the definition of the SSF Application Entity (AE) procedures related to the SSP-SCP interface. The procedures are based on the use of Common Channel Signalling System No. 7 (CCSS No. 7); other signalling systems can be used (e.g. DSS 1-layer 3).
+
+Capabilities not explicitly covered by these procedures may be supported in an implementation dependent manner in the SSP, while remaining in line with clause 2.
+
+The AE, following the architecture defined in the Recommendations Q.700, Q.771 and Q.1400, includes Transaction Capabilities Application Part (TCAP) and one or more ASEs called TC-users. The following subclauses define the TC-user ASE which interfaces with TCAP using the primitives specified in Recommendation Q.771; other signalling systems, such as DSS 1 (layer 3), may be used.
+
+The procedure may equally be used with other signalling message transport systems supporting the application layer structures defined.
+
+In case interpretations for the application entity procedures defined in the following differ from detailed procedures and the rules for using of TCAP service, the statements and rules contained in the detailed subclauses 3.3 and 3.4 shall be followed.
+
+###### 3.1.1.2 Model and interfaces
+
+The functional model of the AE-SSF is shown in Figure 9; the ASEs interface to TCAP to communicate with the SCF, and interface to the call control function (CCF) and the maintenance functions already defined for switching systems. The scope of this Recommendation is limited to the shaded area in Figure 9.
+
+The interfaces shown in Figure 9 use the TC-user ASE primitives specified in Recommendation Q.771 and N-Primitives specified in Recommendation Q.711. The operations and parameters of Intelligent Network Application Protocol (INAP) are defined in clause 2.

+
+### 3.1.1.3 Relations between SSF-FSM and the CCF and maintenance functions
+
+The primitive interface between the SSF-FSM and the CCF/maintenance functions is an internal interface and is not subject to standardization in CS-1. Nevertheless this interface should be in line with the BCSM defined in 4.2.1.2/Q.1214.
+
+The relationship between the BCSM and the SSF-FSM may be described as follows for the case of a call/attempt initiated by an end user, and the case of a call/attempt initiated by IN service logic:
+
+- When a call/attempt is initiated by an end user and processed at an exchange, an instance of a BCSM is created. As the BCSM proceeds, it encounters detection points (DPs, see 4.2/Q.1214). If a DP is armed as a Trigger DP (TDP) an instance of an SSF-FSM is created.
+- If an InitiateCallAttempt is received from the SCF, an instance of a BCSM is created, as well as an instance of an SSF-FSM.
+
+The SSF logic should:
+
+- perform the DP processing actions specified in 4.2.2.7/Q.1214, including if DP criteria are met;
+- check if traffic mechanisms are active;
+- check for SCF accessibility;
+- handle service feature interactions.
+
+The SSF hands control back to the CCF at least in the following cases:
+
+- If call gapping is in effect – The SSF logic will instruct the CCF to terminate the call with the appropriate treatment.
+- If service filtering is in effect – The call is counted (if required) and the SSF logic instructs the CCF to handle the call with the appropriate treatment.
+- If a trigger (TDP) criteria match is not found (e.g. insufficient information to proceed) – The SSF logic returns call control to the CCF.
+- If the call is abandoned – The SSF logic returns call control to the CCF and continues processing as described in 3.1.1.5.
+- If the destination SCF is not accessible – The SSF logic will instruct the CCF to route the call if possible (e.g. default routing to a terminating announcement).
+- If there is an existing control relationship for the call and the DP is armed as an EDP-R – The SSF returns call control to the CCF.
+
+The management functions related to the execution of operations received from the SCF are executed by the SSF Management Entity (SSME). The SSME comprises a SSME-Control and several instances of SSME FSMs. The SSME-control interfaces the different SSF FSMs and SSME FSMs respectively and the Functional Entity Access Manager (FEAM). Figure 10 shows the SSF Interfaces.
+
+![Diagram of SSF interfaces showing FEAM, SSME-Control, SSF FSMs, and SSME FSMs within an SSF boundary, interfacing with SRF and SCF.](9bafc60bf378685e5e246c3ffad7b792_img.jpg)
+
+The diagram illustrates the internal architecture of the SSF (Service Switching Function) and its interfaces. A central oval labeled 'SSME-Control' is connected to a circle labeled 'FEAM' above it and to several circles below it. The circles below 'SSME-Control' are labeled 'SSF FSM', 'SSF FSM', 'SSME FSM', and 'SSME FSM', with ellipses between the second and third circles. All these circles are contained within a dashed rectangular boundary labeled 'SSF' at the bottom. The 'FEAM' circle is connected to two external entities: 'SRF' (Service Requesting Function) on the left and 'SCF' (Service Controlling Function) on the right, both via double-headed arrows. The 'SSF' boundary is labeled 'T1169150-94/d10' at the bottom right.

+SSF interfaces
+
+The Functional Entity Access Manager (FEAM) provides the low level interface maintenance functions including the following:
+
+- 1) establishing and maintaining the interfaces to the SCF and SRF;
+- 2) passing and queuing (when necessary) the messages received from the SCF and SRF to the SSME-Control;
+- 3) formatting, queuing (when necessary), and sending the messages received from the SSME-Control to the SCF and SRF.
+
+The SSME-control maintains the dialogues with the SCF and SRF on behalf of all instances of the SSF Finite State Machine (FSM). These instances of the SSF FSM occur concurrently and asynchronously as calls occur, which explains the need for a single entity that performs the task of creation, invocation and maintenance of the SSF-FSMs. In particular the SSME-control performs the following tasks:
+
+- 1) Interprets the input messages from other FEs and translates them into corresponding SSF FSM events.
+- 2) Translates the SSF-FSM outputs into corresponding messages to other FEs.
+- 3) Captures asynchronous (with call processing) activities related to management or supervisory functions in the SSF and creates an instance of a SSME-FSM. For example, the SSME provides non-call associated treatment due to changes in Service Filtering or Call Gapping. Therefore, the SSME-control separates the SSF-FSM from the Call Gapping and Service Filtering functions by creating instances of SSME-FSMs for each context of management related operations.
+
+The different contexts of the SSME-FSMs may be distinguished based on the address information provided in the initiating operations. In the case of service filtering this address information is given by filteringCriteria, i.e. all ActivateServiceFiltering operations using the same address, address the same SSME-FSM handling this specific service filtering instance. For example ActivateServiceFiltering operations providing different filtering Criteria cause the invocation of new SSME-FSMs.
+
+The SSF-FSM passes call handling instructions to the related instances of the BCSM as needed. DPs may be dynamically armed as Event DPs, requiring the SSF-FSM to remain active. At some point, further interaction with the SCF is not needed, and the SSF-FSM may be terminated while the BCSM continues to handle the call as needed. A later TDP in the BCSM may result in a new instance of the SSF-FSM for the same call.
+
+Consistent with the single-ended control characteristic of IN service features for CS-1, the SSF-FSM only applies to a functionally separate call portion (e.g. the originating BCSM or the terminating BCSM in a two-party call, but not both).
+
+#### **3.1.1.4 SSF Management Finite State Machine (SSME-FSM)**
+
+The SSME-FSM state diagram is described in Figure 11.
+
+The SSME-FSM is independent of the individual SSF-FSMs.
+
+The non-call associated treatment state is entered from the IdleManagement state when one of the following non-call associated operations is received (transition em1):
+
+- RequestCurrentStatusReport;
+- RequestEveryStatusChangeReport;
+- RequestFirstStatusMatchReport;
+- ActivateServiceFiltering;
+- CallGap;
+- ActivityTest.
+
+The CallGap operation may be received inside as well as outside a call context transaction. The ActivityTest operation applies to call context transactions only. The ActivateServiceFiltering operation may be received outside a call context only.

+
+During this state the following events can occur:
+
+- given that service filtering is active, the SSF needs to send a service filtering response to the SCF: the SSME-FSM remains in this state (transition em3);
+- given that service filtering is active, the SSF needs to increment a counter: the SSME FSM remains in this state (transition em3);
+- given that service filtering is active and the service filtering duration expires: the SSME should move to the Idle Management state (transition em2) and send a ServiceFilteringResponse operation to the SCF;
+- given that status report is active previously requested by a RequestEveryStatusChangeReport operation, the SSF needs to send a StatusReport operation: the SSF remains in this state (transition em3);
+- given that status report is active previously requested by a RequestFirstStatusMatchReport operation, the SSF needs to send a StatusReport operation: the SSF transits to Idle Management state (transition em2);
+- given that status report is active previously requested by a RequestFirstStatusMatchReport or a RequestEveryStatusMatchReport operation, and the CancelStatusReportRequest operation is received by the SSF or the status report duration expires, the SSME-FSM should move to the Idle Management state (transition em2);
+- given that status report is active previously requested by a RequestCurrentStatusReport operation, the SSF sends the StatusReport operation, the SSME-FSM should move to the Idle Management state (transition em2);
+- if call gap related duration timer expires, the SSME-FSM should move to the Idle Management state (transition em2);
+- given that call gap/service filtering is active, another CallGap/ActivateServiceFiltering operation could be received by the SSF, which has the same gapping/filtering criteria: the second “filter” or “gap” replace the first one (transition em3) unless the duration timer value is equal to zero, in which case the SSME-FSM should move to the Idle Management state (transition em2).
+
+All other operations have no effect on the SSME-FSMs; the operations are passed by the SSME-Control to the relevant SSF-FSM.

+
+FIGURE 12/Q.1218  
+**SSF finite state machine**
+
+Each state is discussed in the following subclauses. General rules applicable to more than one state are addressed here.
+
+One or a sequence of components received in one or more TCAP messages may include a single operation or multiple operations, and is processed as follows:
+
+- Process the operations in the order in which they are received.
+- Each operation causes a state transition independent of whether or not a single operation or multiple operations are received in a message.
+
+- The SSF examines subsequent operations in the sequence. As long as sequential execution of these operations would leave the FSM in the same state, it will execute them (e.g. RequestReportBCSMEVENT). If a subsequent operation causes a transition out of the state, then the following operations should be buffered until the current operation has been executed. In all other cases, await an event that would cause a transition out of the current state (such an event would be the completion of operation being executed, or reception of an external event). An example of this is as follows:
+  - The SSF receives the operations FurnishChargingInformation, ConnectToResource, and PlayAnnouncement in a component sequence inside a single TCAP message. Upon receipt of this message, these operations are executed up to and including ConnectToResource while the SSF is in the Waiting For Instructions state. As the ConnectToResource operation is executed (and when, or after the FurnishChargingInformation operation has been completed), the SSF-FSM will transit to the Waiting For End Of User Interaction state. The PlayAnnouncement operation is relayed to the SRF while the SSF is in Waiting For End Of User Interaction state.
+- If there is an error in processing one of the operations in the sequence, the SSF-FSM processes the error (see below) and discards all remaining operations in the sequence.
+- If an operation is not understood or is out of context (i.e. violates the SACF rules defined by the SSF-FSM) as described above, ABORT the interaction. For example, when the SSF-FSM applies to an originating BCSM, then receiving SelectFacility operation would be out of context since this applies only to the terminating half of the BCSM.
+
+In any state, if there is an error in a received operation, the maintenance functions are informed and the SSF-FSM remains in the same state as when it received the erroneous operation; depending on the class of the operation, the error could be reported by the SSF to the SCF using the appropriate component (see Recommendation Q.774).
+
+In any state (except idle), if the calling party abandons the call before it is answered (i.e. before the Active PIC in the BCSM), then the SSF-FSM should instruct the CCF to clear the call and ensure that any CCF resources allocated to the call have been de-allocated, then continue processing as follows:
+
+- If the Abandon DP is not armed and there is no call information request pending, then transition to the idle state.
+- If the Abandon DP is not armed and there is a CallInformationRequest pending, send a CallInformationReport, then transit to the Idle state.
+- If the Abandon DP is armed as an EDP-R, send an EventReportBCSM or a DP specific operation, then transit to the Waiting For Instructions state. If a CallInformationRequest is pending, a CallInformationRequest shall be sent before the corresponding EventReportBCSM or a DP specific operation is sent.
+- If the Abandon DP is armed as an EDP-N and there is no CallInformationRequest pending, send an EventReportBCSM or a DP specific operation, then transit to the Idle state.
+- If the Abandon DP is armed as an EDP-N and there is a CallInformationRequest pending, send an EventReportBCSM or a DP specific operation, followed by a CallInformationReport, then transit to the Idle state.
+- Other pending requests that should be treated in the same way as the CallInformationRequest in the above list is the ApplyCharging.
+
+In any state (except Idle), if a call party disconnects from a stable call (i.e. from the Active PIC in the BCSM), then the SSF-FSM should process this event as follows:
+
+- If the Disconnect DP is not armed for that specific leg and there is no CallInformationRequest pending, transit to the Idle state.
+- If the Disconnect DP is not armed and there is a CallInformationRequest pending, send a CallInformationReport and transit to the Idle state.
+
+- If the Disconnect DP is armed as an EDP-R for that specific leg, send an EventReportBCSM or a DP specific operation, then transit to the Waiting For Instructions state. If a Call Information Request is pending, a CallInformationReport shall be sent before the corresponding EventReportBCSM or a DP specific operation is sent.
+- If the Disconnect DP is armed as an EDP-N and there is no CallInformationRequest pending, send an EventReportBCSM or a DP specific operation, then transit to the Idle state.
+- If the Disconnect DP is armed as an EDP-N and there is a CallInformationRequest pending, send an EventReportBCSM or a DP specific operation and a CallInformationReport, then transit to the Idle state.
+- Other pending requests that should be treated in the same way as the CallInformationRequest in the above list is the ApplyCharging.
+
+In any state (except Idle), an EventNotificationCharging can be sent to the SCF, if previously requested by a RequestNotificationCharging and if the charging event has been detected by the CCF. In this case no state transition takes place.
+
+The SSF has an application timer,  $T_{\text{SSF}}$ , whose purpose is to prevent excessive call suspension time and to guard the association between the SSF and the SCF.
+
+Timer  $T_{\text{SSF}}$  is set in the following cases:
+
+- When the SSF sends an InitialDP, DP specific (refer to 3.1.1.5.2 State c: Waiting For Instructions), or AssistRequestInstructions operation (refer to 3.1.1.6.2 State b: Waiting For Instructions in assisting/handoff case). While waiting for the first response from the SCF, the timer  $T_{\text{SSF}}$  can be reset only once by a ResetTimer operation. Subsequent to the first response, the timer can be reset any number of times.
+- When the SSF enters the Waiting For Instructions state (refer to 3.1.1.5.2) under any other condition than the ones listed in the previous case. In this case the SCF may reset the  $T_{\text{SSF}}$  timer using the ResetTimer operation any number of times.
+- When the SSF receives a HoldCallInNetwork operation (refer to 3.1.1.5.2 State c: Waiting For Instructions). In this case the SCF may reset  $T_{\text{SSF}}$  using the ResetTimer operation any number of times.
+- When the SSF enters the Waiting For End of User Interaction state or the Waiting For End of Temporary Connection state (refer to 3.1.1.5.3 and 3.1.1.5.4). In these cases the SCF may reset  $T_{\text{SSF}}$  using the ResetTimer operation any number of times.(OPTIONAL).
+
+NOTE – This "OPTIONAL" means that the application timer  $T_{\text{SSF}}$  is optionally set. Whether it is used or not depends on implementation. But it must be synchronized with  $T_{\text{SCF-SSF}}$  in the SCSM.
+
+In the four above cases  $T_{\text{SSF}}$  may respectively have four different values as defined by the application.
+
+When receiving or sending any operation which is different from the above, the SSF should reset  $T_{\text{SSF}}$  to the last used set value. This value is either one associated to the four different cases as listed above, or received in a ResetTimer operation, whatever occurred last. In the monitoring state (refer to 3.1.1.5.5)  $T_{\text{SSF}}$  is not used.
+
+On expiration of  $T_{\text{SSF}}$  the SSF-FSM transitions to the idle state, aborts the interaction with the SCF and the CCF progresses the BCSM if possible.
+
+The SSF state diagram contains the following transitions (events):
+
+- e1 TDP-N encountered
+- e3 InitiateCallAttempt received
+- e4 TDP-R encountered
+- e5 User interaction requested
+- e6 User interaction ended
+- e7 Temporary connection created
+- e8 Temporary connection ended
+- e9 Idle return from wait for instruction
+
+- e10 EDP-R encountered
+- e11 Routing instruction received
+- e12 EDP-N last encountered or ReleaseCall received or Cancel(allRequests) received
+- e13 Waiting for End of User Interaction state no change
+- e14 Waiting for Instructions state no change
+- e15 Waiting for End of Temporary Connection state no change
+- e16 Monitoring state no change
+- e17 Abandon (from any state) (not shown in the SSF state diagram)
+- e18 Disconnect (from any state) (not shown in the SSF state diagram)
+- e19 Non-Call Associated Treatment from any state (not shown in the SSF state diagram)
+
+The SSF state diagram contains the following states:
+
+- State a Idle
+- State c Waiting for Instructions
+- State d Waiting for End of User Interaction
+- State e Waiting for End of Temporary Connection
+- State f Monitoring
+
+### 3.1.1.5.1 State a – Idle
+
+The SSF-FSM enters the Idle state under a variety of conditions, as described below.
+
+The SSF-FSM enters the Idle state when sending or receiving an ABORT TCAP primitive due to abnormal conditions in any state.
+
+The SSF-FSM enters the Idle state when one of the following occurs:
+
+- when the call is abandoned or one or more call parties disconnect in any other state under the conditions identified in 3.1.1.5;
+- when a Connect or proceed call processing operation is processed in the Waiting for Instructions state, and no EDPs are armed and there are no outstanding report requests (transition e9);
+- when the application timer  $T_{\text{SSF}}$  expires in one of the states: Waiting for Instructions, Waiting for End of User Interaction or Waiting for End of Temporary Connection;
+- when a ReleaseCall operation is processed in Waiting for Instructions (transition e9) or Monitoring (transition e12);
+- when the last EDP-N is encountered in the Monitoring state, and there are no EDP-Rs armed and no monitoring is active for charging events (transition e12);
+- when the last charging event is encountered in the Monitoring state, and there are no EDPs armed (transition e12).
+
+When transiting to the Idle state, if there is a CallInformationRequest pending (see 3.1.1.5), the SSF sends a CallInformationReport operation to the SCF before returning to Idle. Once in the Idle state, if status reporting is still active the SSF deactivates it, any outstanding responses to send to the SCF are discarded.
+
+During this state the following call-associated events can occur:
+
+- indication from the CCF that an armed TDP is encountered related to a possible IN call/service attempt, the SSF-FSM acts as described below:
+  - if the DP is a TDP-N, send a generic InitialDetectionPoint or DP-specific operation (see Note) to the SCF, as determined from DP processing; there is no resulting transition to a different state (transition e1);
+
+- if the DP is a TDP-R, send a generic InitialDetectionPoint or DP-specific operation (see Note) to the SCF, as determined from DP processing, and transit to the Waiting for Instructions state (transition e4);
+- the rules for DP processing are described in Recommendation Q.1214, section "DP Processing";
+- a message related to a new transaction containing an InitiateCallAttempt operation is received from the SCF: in this case the SSF-FSM moves to the state Waiting for Instructions (transition e3).
+
+Any other operation received from the SCF while the SSF is in Idle state should be treated as an error. The event should be reported to the maintenance functions and the transaction should be aborted according to the procedure specified in TCAP (see Recommendation Q.774).
+
+NOTE – DP specific operations are the following (refer to clause 2): TAnswer, TDisconnect, TermAttemptAuthorized, TMidCall, TNoAnswer, AnalysedInformation, TBusy, CollectedInformation, OAnswer, OCalledPartyBusy, ODisconnect, OMidCall, ONoAnswer, OriginationAttemptAuthorized, RouteSelectFailure.
+
+### 3.1.1.5.2 State c – Waiting for Instructions
+
+This state is entered from the Idle state, as indicated above (transition e4), directly from the Idle state on receipt at the SSF of a TC-BEGIN indication primitive containing an InitiateCallAttempt operation from the SCF (transition e3), from the state Monitoring on detection of an EDP-R (transition e10), from the state Waiting for End of User Interaction on occurrence of call disconnect from/to the SRF (transition e6), or from the state Waiting for End of Temporary Connection on occurrence of disconnection of temporary connection (transition e8).
+
+In this state the SSF-FSM is waiting for an instruction from the SCF; call handling is suspended and an application timer ( $T_{\text{SSF}}$ ) should be set on entering this state.
+
+During this state the following events can occur:
+
+- The user dials additional digits (applies for open-ended numbering plans) – The CCF should store the additional digits dialled by the user.
+- The user abandons or disconnects. This should be processed in accordance with the general rules in 3.1.1.5.
+- The application Timer  $T_{\text{SSF}}$  expires – The SSF-FSM moves to the Idle state, the CCF routes the call if possible (e.g. default routing to a terminating announcement), the  $T_{\text{SSF}}$  expiration is reported to the maintenance functions and the transaction is aborted.
+- An operation is received from the SCF – The SSF-FSM acts according to the operation received as described below.
+
+The following operations may be received from the SCF and processed by the SSF with no resulting transition to a different state (transition e14):
+
+- HoldCallInNetwork;
+- RequestReportBCSMEEvent;
+- RequestNotificationChargingEvent;
+- ResetTimer;
+- FurnishChargingInformation;
+- ApplyCharging;
+- CallInformationRequest;
+- SendChargingInformation;
+- Cancel.
+
+The following operations may be received from the SCF and processed by the SSF, causing a state transition to Waiting for End of User Interaction state (transition e5):
+
+- ConnectToResource.
+
+The following operations may be received from the SCF and processed by the SSF, causing a state transition to Waiting for End of Temporary Connection state (transition e7):
+
+- EstablishTemporaryConnection
+
+The following operations may be received from the SCF and processed by the SSF, causing a state transition to either Monitoring state (if any EDPs were armed or any reports were requested) (transition e11) or Idle state (transition e9):
+
+- Connect;
+- CollectInformation;
+- AnalyseInformation;
+- SelectRoute;
+- SelectFacility;
+- Continue;
+- ReleaseCall.
+
+ReleaseCall operation may be received from the SCF. In this case, the SSF-FSM should instruct the CCF to clear the call and ensure that any CCF resources allocated to the call have been de-allocated, then continue processing as follows:
+
+- if neither CallInformationRequest nor ApplyChargingReport operation has been requested, the SSF-FSM transits to the Idle state (transition e9);
+- if CallInformationRequest or ApplyChargingReport operation has been requested, the SSF sends each operation which has been requested from SCF, and then the SSF-FSM transits to the Idle state (transition e9).
+
+When processing the above operations, any necessary call handling information is provided to the Call Control Function (CCF).
+
+Any other operation received in this state should be processed in accordance with the general rules in 3.1.1.5.
+
+### 3.1.1.5.3 State d – Waiting for End of User Interaction
+
+The SSF enters this state from the Waiting for Instructions state (transition e5) on the reception of one of the following operations:
+
+- ConnectToResource.
+
+During this state the following events can occur:
+
+- A valid SCF-SRF operation [i.e. PlayAnnouncement, PromptAndCollectUserInfoInformation, and Cancel(invokeID)] for relaying is received and is correct, the operation is transferred to the SRF for execution. The SSF-FSM remains in the Waiting for End of User Interaction state (transition e13).
+- A valid SRF-SCF operation (i.e. SpecializedResourceReport and ReturnResult from PromptAndCollectUserInfoInformation) for relaying is received and is correct, the operation is transferred to the SCF. The SSF-FSM remains in the Waiting for End of User Interaction state (transition e13).
+- The application timer  $T_{\text{SSF}}$  expires (if it was set) – The SSF-FSM moves to the Idle state, the CCF routes the call if possible (e.g. default routing to a terminating announcement), the  $T_{\text{SSF}}$  expiration is reported to the maintenance functions and the transaction is aborted.
+- An operation is received from the SCF – The SSF-FSM acts according to the operation received as described below.
+- The user abandons – This should be processed in accordance with the general rules in 3.1.1.5.
+
+The following operations may be received from the SCF and processed by the SSF with no resulting transition to a different state (transition e13):
+
+- RequestNotificationChargingEvent;
+- ResetTimer;
+- FurnishChargingInformation;
+- ApplyCharging;
+- Send Charging Information.
+
+The DisconnectForwardConnection operation may be received from the SCF and processed by the SSF in this state. Call disconnect can also be received from the SRF. In both cases this causes the release of the connection to the SRF and the transition to the Waiting for Instructions state. The disconnection is not transferred to the other party (transition e6).
+
+Any other operation received in this state should be processed in accordance with the general rules in 3.1.1.5.
+
+#### 3.1.1.5.4 State e – Waiting for End of Temporary Connection
+
+The SSF enters this state from the Waiting for Instructions state (transition e7) upon receiving an EstablishTemporaryConnection operation.
+
+The call is routed to the assisting SSF-SRF and call handling is suspended while waiting for the end of the assisting procedure. The timer  $T_{\text{SSF}}$  is active in this state (whether it is used or not is optional).
+
+During this state the following events can occur:
+
+- The application timer  $T_{\text{SSF}}$  expires (if it was set) – The SSF-FSM moves to the Idle state, the CCF routes the call if possible (e.g. default routing to a terminating announcement), the  $T_{\text{SSF}}$  expiration is reported to the maintenance functions and the transaction is aborted.
+- The receipt of an indication of disconnection of forward connection from the CCF – In this case, the SSF moves to the Waiting for Instructions state (transition e8). The disconnection is not transferred to the calling party.
+- The user abandons – This should be processed in accordance with the general rules in 3.1.1.5
+- An operation is received from the SCF – The SSF acts according to the operation received as described below.
+
+The following operations can be received from the SCF and processed by the SSF with no resulting transition to a different state (transition e15):
+
+- RequestNotificationChargingEvent;
+- ResetTimer;
+- FurnishChargingInformation;
+- ApplyCharging;
+- SendChargingInformation.
+
+The DisconnectForwardConnection operation may be received from the SCF and processed by the SSF in this state. Call disconnect can also be received from the SRF. In both cases this causes the release of the connection to the SRF and the transition to the Waiting for Instructions state. The disconnection is not transferred to the other party (transition e8).
+
+Any other operation received in this state should be processed in accordance with the general rules in 3.1.1.5.
+
+#### 3.1.1.5.5 State f – "Monitoring"
+
+The SSF enters this state from the Waiting For Instructions state (transition e11) upon receiving a Connect, CollectInformation, AnalyseInformation, SelectRoute, SelectFacility, Continue, operation or processing an Initiate CallAttempt operation when one or more EDPs are armed or/and there are other reports pending (see 3.1.1.5).
+
+In this state the timer  $T_{\text{SSF}}$  is not used, i.e. the expiration of  $T_{\text{SSF}}$  does not have any impact on the SSF-FSM.
+
+During this state the following events can occur:
+
+- An EDP-N should be reported to the SCF by sending an EventReportBCSM operation or a DP specific operation; the SSF-FSM should remain in the Monitoring state (transition e16) if one or more EDPs are armed or there are report requests pending. The SSF-FSM should move to the Idle state (transition e12) if there are no remaining EDPs armed or there are no report requests pending.
+
+If the event causing a CallInformationReport is also detected by an armed EDP-N, then the CallInformationReport shall be sent immediately before the corresponding EventReportBCSM or a DP specific operation is sent.
+
+- An EDP-R should be reported to the SCF by sending an EventReportBCSM operation or a DP specific operation; the SSF-FSM should move to the Waiting For Instructions state (transition e10).
+- If the event causing a CallInformationReport is also detected by an armed EDP-R, then the CallInformationReport shall be sent immediately after the corresponding EventReportBCSM or a DP specific operation is sent.
+- The receipt of an END or ABORT primitive from TCAP has no effect on the call; the call may continue or be completed with the information available. In this case, the SSF-FSM transits to the Idle state (transition e12), disassociating the SSF-FSM from the call.
+- An operation is received from the SCF: The SSF-FSM acts according to the operation received as described below.
+- The user abandons or disconnects. This should be processed in accordance with the general rules in 3.1.1.5.
+
+The following operations can be received from the SCF and processed by the SSF with no resulting transition to a different state (transition e16):
+
+- RequestNotificationChargingEvent;
+- SendChargingInformation;
+- FurnishChargingInformation;
+- ApplyCharging.
+
+The RequestReportBCSMEVENT operation may be received from the SCF. In this case, the SSF-FSM transits as follows:
+
+- if one or more EDPs are armed or a part of armed EDPs are disarmed, the SSF-FSM transits back to the same state (transition e16);
+- if all of armed EDPs are disarmed and there is outstanding CallInformationRequest, EventNotificationCharging or ApplyChargingReport, the SSF-FSM transits back to the same state (transition e16);
+- if all of armed EDPs are disarmed and there is no outstanding CallInformationRequest, EventNotificationCharging or ApplyChargingReport, the SSF-FSM transits to the Idle (transition e12).
+
+The Cancel(allRequests) operation may be received from the SCF and processed by the SSF, causing a state transition to the Idle state (transition e12).
+
+The ReleaseCall operation may be received from the SCF. In this case, the SSF-FSM should instruct the CCF to clear the call and ensure that any CCF resources allocated to the call have been de-allocated, then continue processing as follows:
+
+- if neither CallInformationRequest nor ApplyChargingReport operation has been requested, the SSF-FSM transits to the Idle state (transition e12);
+- if CallInformationRequest or ApplyChargingReport operation has been requested, the SSF sends each operation which has been requested from SCF, and then the SSF-FSM transits to the Idle state (transition e12).
+
+Any other operation received in this state should be processed in accordance with the general rules in 3.1.1.5.
+
+### 3.1.1.6 Assisting/Handoff SSF-FSM
+
+This subclause describes the SSF-FSM related to the Assisting/Handoff SSF. The assisting SSF is structured as defined in 3.1.1.1 through 3.1.1.5. The Handoff FSM for CS-1 applies only to the case where final treatment is to be applied.
+
+Within this subclause, the term "Assisting SSF" refers to both Assisting and Handoff SSFs unless an explicit indication to one or the other is provided.
+
+The Assisting/Handoff SSF state diagram contains the following transitions (events) (see Figure 13):
+
+- ea1 Assist/Handoff detected
+- ea2 Assist/Handoff fail/success
+- ea3 User interaction requested
+- ea4 User interaction ended
+- ea5 Waiting For Instruction state no change
+- ea6 Waiting For End Of User Interaction state no change

+
+### 3.1.1.6.1 State a – Idle
+
+The SSF-FSM enters the Idle state when one of the following occurs:
+
+- when sending or receiving an ABORT TCAP primitive due to abnormal conditions in any state;
+- given a temporary connection between an initiating SSF and the Assisting SSF, when a bearer channel disconnect is received from the initiating SSF (transition ea2).
+
+Once in the Idle state, if there are any outstanding responses to send to the SCF, they are discarded by the Assisting SSF.
+
+The Assisting SSF-FSM transits from the Idle state to the Waiting for Instructions state on receipt of an assist indication at the assisting SSF from another SSF (transition ea1).
+
+Any operation received from the SCF while the Assisting SSF is in Idle state should be treated as an error. The event should be reported to the maintenance functions and the transaction should be aborted according to the procedure specified in TCAP (see Recommendation Q.774).
+
+### 3.1.1.6.2 State b – Waiting for Instructions
+
+This state is entered from the Idle state on receipt of a connect at an SSF from another SSF indicating that an assist is required, based on an implementation dependent detection mechanism (transition ea1).
+
+Before entering this state, the SSF sends an AssistRequestInstructions operation to the SCF. In this state the Assisting SSF-FSM is waiting for an instruction from the SCF; call handling is suspended and an application timer ( $T_{\text{SSF}}$ ) should be set on entering this state.
+
+During this state the following events can occur:
+
+- The application timer  $T_{\text{SSF}}$  expires – The Assisting SSF-FSM moves to the Idle state (transition ea2) and the expiration is reported to the maintenance functions and the transaction is aborted.
+- An operation is received from the SCF – The SSF-FSM acts according to the operation received as described below.
+- A bearer channel disconnect is received from the initiating SSF and the FSM moves to the Idle state (transition ea2).
+
+The following operations may be received from the SCF and processed by the Assisting SSF with no resulting transition to a different state (transition ea5):
+
+- ResetTimer;
+- FurnishChargingInformation;
+- ApplyCharging;
+- SendChargingInformation.
+
+The following operations can be received from the SCF and processed by the Assisting SSF, causing a state transition to Waiting for End of User Interaction state (transition ea3):
+
+- ConnectToResource.
+
+In the case of Handoff SSF the ReleaseCall operation can be received from the SCF. The Handoff SSF-FSM should instruct the CCF to clear the call and ensure that any CCF resources allocated to the call have been de-allocated, then continue processing as follows:
+
+- if ApplyChargingReport operation is not requested, the Handoff SSF-FSM transits to the Idle state (transition ea2);
+- if ApplyChargingReport operation has been requested, the Handoff SSF sends ApplyChargingReport to SCF and then the Handoff SSF-FSM transits to the Idle state (transition ea2).
+
+Note that the above operation is allowed only in the Handoff SSF. In the case where an implementation is not capable of differentiating between a Handoff or an assisting SSF case, it may execute the ReleaseCall operation in the assisting SSF.
+
+Any other operation received in this state should be processed in accordance with the general rules in 3.1.1.5.
+
+Note that multiple Handoff procedures are not covered by this Recommendation.
+
+### 3.1.1.6.3 State c – Waiting for End of User Interaction
+
+The Assisting SSF enters this state from the Waiting for Instructions state (transition ea3) on the reception of one of the following operations:
+
+- ConnectToResource.
+
+During this state the following events can occur:
+
+- A valid SCF-SRF operation [i.e. Play announcement, prompt and collect user information, and cancel (announcement)] for relaying is received and is correct, the operation is transferred to the SRF for execution. The SSF-FSM remains in the Waiting for End of User Interaction state (transition ea6).
+- When the SRF indicates to the assisting SSF the end of user interaction by initiating disconnection the assisting SSF-FSM returns to the Waiting for Instructions state (only in handoff case) (transition ea4).
+- The application timer  $T_{SSF}$  expires – The SSF-FSM moves to the Idle state, the CCF routes the call if possible (e.g. default routing to a terminating announcement), the  $T_{SSF}$  expiration is reported to the maintenance functions and the transaction is aborted.
+- An operation is received from the SCF – The SSF-FSM acts according to the operation received as described below.
+- A bearer channel disconnect is received from the initiating SSF – The assisting SSF-FSM moves to the Idle state, the connection to the SRF is released and the transaction is terminated (transition ea7).
+
+The following operation can be received from the SCF and processed by the SSF with no resulting transition to a different state (transition ea6):
+
+- ResetTimer.
+
+The DisconnectForwardConnection operation may be received from the SCF and processed by the assisting/handoff SSF in this state, causing a transition to the Waiting for Instructions state (transition ea4). This procedure is only valid if a ConnectToResource was previously processed to cause a transition into the Waiting for End of User Interaction state.
+
+Any other operation received in this state should be processed in accordance with the general rules in 3.1.1.5.
+
+### **3.1.2 SCF application entity procedures**
+
+#### **3.1.2.1 General**
+
+This subclause provides the definition of the SCF Application Entity (AE) procedures related to the SCF-SSF/SRF/SDF interfaces. The procedures are based on the use of Signalling System No. 7 (SS No.7); other signalling systems can also be used.
+
+In addition, other capabilities may be supported in an implementation-dependent manner in the SCP, AD or SN.
+
+The AE, following the architecture defined in Recommendations Q.700, Q.771 and Q.1400, includes Transaction Capabilities Application Part (TCAP) and one or more ASEs called TC-users. The following subclauses define the TC-user ASE and SACF/MACF rules, which interface with TCAP using the primitives specified in Recommendation Q.774.
+
+The procedure may equally be used with other message-based signalling systems supporting the Application Layer structures defined. By no means is this text intended to dictate any limitations to Service Logic Programs (SLPs).
+
+In case interpretations for the AE procedures defined in the following differ from detailed procedures and the rules for using the TCAP service, the statements and rules contained in 3.3 and 3.4 shall be followed.
+
+#### **3.1.2.2 Model and interfaces**
+
+The functional model of the AE-SCF is shown in Figure 14; the ASEs interface with supporting protocol layers to communicate with the SSF, SRF and SDF, and interface to the service logic programs and maintenance functions. The scope of this Recommendation is limited to the shaded area in Figure 14.
+
+NOTE – The SCF-FSM includes several Finite State Machines.
+
+The interfaces shown in Figure 14 use the TC-user ASE primitives specified in Recommendation Q.771 [interface (1)] and N-primitives specified in Recommendation Q.711 [interface (2)]. The operations and parameters of INAP are defined in clause 2.

+### 3.1.2.3 Relationship between the SCF-FSM and the SLPs/maintenance functions
+
+The primitive interface between the SCF-FSM and the SLPs/maintenance functions is an internal interface and is not a subject of standardization in CS1.
+
+The relationship between the SLP and the SCF-FSM may be described as follows (for both cases where a call is initiated by an end user and by IN service logic):
+
+- If a request for IN call processing is received from the SSF, an instance of an SCF Call State Model (SCSM) is created, and the relevant SLP is invoked.
+- When initiation of a call is requested from service logic, an instance of the SCSM is created.
+
+In either case, the SCF-FSM handles the interaction with the SSF-FSM (and the SRF-FSM and SDF-FSM) as required, and notifies the SLP of events as needed.
+
+The management functions related to the execution of operations received from the SCF are executed by the SCF Management Entity (SCME). The SCME is comprised of the SCME-Control and multiple instances of SCME FSMs. The SCME-Control interfaces different SCF Call State Models (SCSMs) and the Functional Entity Access Manager (FEAM). Figure 15 shows the SCF-FSM structure.
+
+![Diagram of SCF-FSM structure showing FEAM, SCME-Control, SCSMs, and SCME FSMs within an SCF boundary, interfacing with SSF and SRF.](c05763eff20551449de1eac378fed769_img.jpg)
+
+The diagram illustrates the SCF-FSM structure. A dashed rectangular box labeled 'SCF' at the bottom contains several components. At the top, a circle labeled 'FEAM' has bidirectional arrows pointing to it from 'SSF' on the left and 'SRF' on the right. Below 'FEAM' is an oval labeled 'SCME-Control', connected to 'FEAM' by a bidirectional vertical arrow. Below 'SCME-Control' are four circles: two labeled 'SCSM' (with a dashed line between them) and two labeled 'SCME FSM'. Each of these four circles has a bidirectional arrow pointing to the 'SCME-Control' oval. At the bottom right of the dashed box is the text 'T1169150-94/d15'.

+
+FIGURE 15/Q.1218  
+**SCF-FSM structure**
+
+The following text systematically describes the procedural aspects of the interface between the SCF and other functional entities, with the main goal of specifying the proper order of operations rather than the functional capabilities of the entities. Consequently, this text describes only a subset of the SCF functional capabilities.
+
+The procedural model associates an SCSM with each query from the SSF. The SCSM maintains dialogues with the SSF, SRF and SDF on behalf of service logic.
+
+Multiple requests may be executed concurrently and asynchronously by the SCF, which explains the need for a single entity that performs the tasks of creation, invocation and maintenance of the SCF-FSM objects. This entity is called the SCF Management Entity-Control (SCME-Control). In addition to the above tasks, the SCME maintains the dialogues with the SSF, SDF and SRF on behalf of all instances of the SCF-FSMs. In particular, the SCME-Control:
+
+- 1) interprets the input messages from other FEs and translates them into corresponding SCSM events;
+- 2) translates the SCSM outputs into corresponding messages to other FEs;
+
+- 3) performs some asynchronous (with call processing) activities (one such activity is flow control). It is the responsibility of the SCME-control to detect nodal overload and send the Overload Indication (e.g. Automatic Call Gap) to the SSF to place flow control on queries. Other such activities include non-call associated treatment due to changes in Service Filtering, Call Gapping, or Resource Monitoring status and also provision of resource status messages to the SSF;
+- 4) supports persistent interactions between the SCF and other FEs; and
+- 5) performs asynchronous (with call processing) activities related to management and supervisory functions in the SCF and creates an instance of a SCME-FSM. For example, the SCME provides the non-call associated treatment due to changes in Service Filtering. Therefore, the SCME-Control separates the SCSM from the Service Filtering by creating instances of SCME-FSMs for each context of related operations.
+
+The different contexts of the SCME-FSMs may be distinguished based on the address information provided in the initiating operations. In the case of service filtering, this address information is given by Filtering Criteria, i.e. all ActivateServiceFiltering operations using the same address, address the same SCME-FSM handling this specific service filtering instance. For example, ActivateServiceFiltering operations providing different Filtering Criteria cause the invocation of new SCME-FSMs.
+
+Finally, the FEAM relieves the SCME of low-level interface functions. The functions of the FEAM include:
+
+- 1) establishing and maintaining the interfaces to the SSF, SRF and SDF;
+- 2) passing (and queueing when necessary) the messages received from the SSF, SRF and SDF to the SCME; and
+- 3) formatting, queueing (when necessary), and sending messages received from the SCME to the SSF, SRF and SDF.
+
+Note that although the SCSM includes a state and procedures concerning queue management, this type of resource management only represents one way of managing network call queues. Another alternative is to let the SSF-CCF manage call queues; however, the technical details of how the SSF-CCF performs queue management is beyond the scope of IN. As such, the RCO (see 3.1.2.4.5) and the queueing state of the SCSM (State 2.2), along with its relevant sub-states, events and procedures, are only required and applicable in the case where queue management is performed in the SCF.

+- **RequestCurrentStatusReport;**
+- **RequestEveryStatusChangeReport;**
+- **RequestFirstStatusMatchReport;**
+- **CancelStatusReport (including the Invoke ID previously used for request FirstStatusMatchReport or RequestEveryStateChangeReport operations);**

+- **CallGap; and**
+- **ActivityTest.**
+
+Issuing the **CallGap** and **ActivityTest** operations does not cause state transitions in the SCME. The procedures for the rest of the above operations are described below.
+
+The operations that are not listed above do not affect the state of the SCME; these operations are passed to the relevant SCSM.
+
+#### 3.1.2.4.1 State M1 – "Status report idle"
+
+The following event<sup>1)</sup> is considered in this state:
+
+- (em1) Request\_Status\_Report\_to\_SSF – This is an internal event, caused by a decision to transmit one of the following operations:
+  - request current status report;
+  - request first status match report;
+  - request every status change report.
+
+This event causes a transition to state M2, Waiting for SSF response status report.
+
+#### 3.1.2.4.2 State M2 – "Waiting for SSF response status report"
+
+The following events are considered in this state:
+
+- (Em2) Status\_Report\_from\_SSF – This is an external event, caused by the reception of the response to the request current status report or request first status match report operation previously issued to the SSF. This event causes a transition out of this state to state M1, Status report idle;
+
+<sup>1)</sup> All events are enumerated, and the number of an event is prefixed with either the letter "E" (for external events) or "e" (for internal ones) and included in parentheses in the beginning of the event name. The scope of event names and numbers is defined by the state machine in which these events appear; the same applies to state names.
+
+- (em3) `Cancel_to_SSF` – This is an internal event, caused by the service logic's need to end status monitoring of the resources in the SSF, and by transmission of cancel status report operation to the SSF. This event takes place only for previously issued request first status match report or request every status change report operations. This event causes a transition to state M1, Status report idle; and
+- (Em4) `Status_Report_for_Every_Change_from_SSF` – This is an external event, caused by reception of the response to the request every status change report operation previously issued to the SSF. This event does not cause a transition out of this state, so the SCSM still remains in state M2, Waiting for the SSF resource status report.
+
+#### 3.1.2.4.3 State M3 – "Service filtering idle"
+
+The following event is considered in this state:
+
+- (em5) `Filtering_Request_to_SSF` – This is an internal event, caused by service logic's need to filter service requests to the SSF, and by transmission of the activate service filtering operation. This event causes a transition to state M4, Waiting for SSF service filtering response.
+
+#### 3.1.2.4.4 State M4 – "Waiting for SSF service filtering response"
+
+In this state, the SCF is waiting for the service filtering response from the SSF. The following events are considered in this state:
+
+- (Em6) `End_of_Service_Filtering_Response_from_SSF` – This is an external event, caused by reception of the response to the request service filtering previously issued to the SSF at the end of the service filtering duration. This event causes a transition out of this state to state M3, Service filtering idle.
+- (em7) `End_of_Service_Filtering` – This is an internal event, caused by the expiration of service filtering duration timer in the SCF. This event causes a transition to state M3, Service filtering idle.
+- (Em8) `Filtering_Response_from_SSF` – This is an external event, caused by reception of the response to the request service filtering operation previously issued to the SSF. This event does not cause a transition out of this state, and the SCSM remains in state M4, Waiting for SSF service filtering response.
+
+When service filtering is active, another service filtering operation could be sent to the SSF that has the same filtering criteria; this second "filter" replaces the first one.
+
+#### 3.1.2.4.5 The Resource Control Object
+
+The Resource Control Object (RCO) is part of the SCF management entity that controls data relevant to resource information.
+
+The RCO consists of:
+
+- 1) a data structure that (by definition) resides in the SDF and can be accessed only via the RCO's methods; and
+- 2) the RCO methods.
+
+For purposes of this Recommendation, no implementation constraints are placed on the structure. The only requirement to the structure is that, for each supported resource, it:
+
+- 1) stores the resource's status (e.g. busy or idle); and
+- 2) maintains the queue of SCSMs that are waiting for this resource. For continuous monitoring, the RCO maintains its knowledge of the status of the resources through use of the request every status change report operation.
+
+The following three methods are defined for the RCO:
+
+- 1) Get\_Resource – This method is used to obtain the address of an idle line on behalf of an SCSM. If the resource is busy, the SCSM is queued for it;
+- 2) Free\_Resource – This method is used when a disconnect notification from the SSF is received. The method either advances the queue (if it is not empty) or makes the resource free (otherwise); and
+- 3) Cancel – This method is used when either the queueing timer has expired or the call has been abandoned.

+The SCSM finite state machine
+
+General rules applicable to more than one state are as follows:
+
+In every state, if there is an error in a received operation, the SLP and the maintenance functions are informed. Generally, the SCSM remains in the same state; however, different error treatment is possible in specific cases as described in 3.3. Depending on the class of the operation, the error can be reported to the SSF, SRF, or SDF (see Recommendation Q.774).
+
+It also holds that, in every state, if the SCSM is informed that the dialogue with the SSF is terminated, then it informs the SLP and returns to the Idle state. In this case, all resources allocated to that call, including those required for relevant dialogues with the other functions, shall be de-allocated. To simplify the diagram, such transitions are not demonstrated in the figures.
+
+When the SLP requests call information, the SCSM transmits the **Call InformationRequest** operation to the SSF, and then **CallInformationReport** is outstanding.
+
+In any state (except Idle), the SCSM may receive the **CallInformationReport** operation from the SSF when the **CallInformationReport** is outstanding. Other pending requests that should be treated in the same way as the **CallInformationRequest** is the **ApplyCharging** operation.
+
+From any state (except Idle), if **CallInformationReport** is outstanding and the SLP indicates that the processing has been completed, the SCSM remains in the same state until it receives the **CallInformationReport** operation.
+
+The general rules for one or a sequence of components sent in one or more TCAP messages, which may include a single operation or multiple operations, are specified in 3.1.1.5 and are not described here.
+
+The SCSM has an application timer,  $T_{SCF-SSF}$ , whose purpose is to reset the timer  $T_{SSF}$ , which is used to prevent excessive call suspension time and to guard the association between the SSF and the SCF.
+
+Timer  $T_{SCF-SSF}$  is set in the following cases:
+
+- when the SCF receives an **InitialDP**, **TAnswer**, **TDisconnect**, **TermAttemptAuthorized**, **TMidCall**, **TNoAnswer**, **AnalysedInformation**, **TBusy**, **CollectedInformation**, **OAnswer**, **OCalledPartyBusy**, **ODisconnect**, **OMidCall**, **ONoAnswer**, **OriginationAttemptAuthorized**, **RouteSelectFailure**, or **AssistRequestInstructions** operation (see 3.1.2.5.2.1 state 2.1: "**Preparing SSF Instructions**", and 3.1.2.5.2.2.1 state 2.2.1: "**Preparing SSF Instructions**"). In this case, this timer is reset when the first request, other than **ResetTimer** operation, is sent to the SSF. Subsequent to the sending of the first response, the SCF may reset  $T_{SSF}$  any number of times, using the **ResetTimer** operation, and also reset  $T_{SCF-SSF}$ . Prior to the sending of the first response, on the expiration of  $T_{SCF-SSF}$ , the SCF may reset  $T_{SSF}$  once, using the **ResetTimer** operation, and also reset  $T_{SCF-SSF}$ . On second expiration of  $T_{SCF-SSF}$ , the SCSM informs SLP and the maintenance functions, and the SCSM transits to the **Idle** state;
+- when the SCF enters the Preparing SSF Instructions state after sending **InitiateCallAttempt** operation or **DisconnectForwardConnection** operation or after receiving a report on EDP-R from the SSF. In this case, the SCF may reset  $T_{SSF}$  using the **ResetTimer** operation any number of times;
+- when the SCF enters the Queueing sub-state (see 3.1.2.5.2.2, State 2.2.2: "**Queueing**"). In this case, on the expiration of timer  $T_{SCF-SSF}$ , the SCF may reset  $T_{SSF}$  using the **ResetTimer** operation any number of times; and
+- when the SCF enters the "**Waiting for Assist Request Instructions**" state or the "**User Interaction**" state (see 3.1.2.5.3.2 and 3.1.2.5.4). In these cases, on the expiration of  $T_{SCF-SSF}$ , the SCF may reset  $T_{SSF}$  using the **ResetTimer** operation any number of times (OPTIONAL).
+
+NOTE – The word "OPTIONAL" refers to the use of the application timer  $T_{SCF-SSF}$ . Whether it is used or not depends on an implementation, but, if used, it must be synchronized with  $T_{SSF}$  in the SSF-FSM.
+
+In all four cases,  $T_{SCF-SSF}$  may respectively have four different values as defined by the application. The value of  $T_{SCF-SSF}$  are smaller than the respective values of  $T_{SSF}$ .
+
+In all other cases, when receiving or sending any operation, the SCF should reset  $T_{SCF-SSF}$ . In the "**Waiting for Notification or Request**" state (see 3.1.2.5.2.3),  $T_{SCF-SSF}$  is not used.
+
+The SCSM also has an application timer,  $T_{ASSIST/HANDOFF}$ , whose purpose is to prevent excessive assist/handoff suspension time. The SCSM sets the timer  $T_{ASSIST/HANDOFF}$  when the SCSM sends the **EstablishTemporaryConnection** or **Select Route/Connect** operation with a correlation ID. This timer is stopped when the SCSM receives the **AssistRequestInstructions** operation from the assisting/handed-off SSF. On expiration of  $T_{ASSIST/HANDOFF}$ , the SCSM informs service logic and the maintenance functions. Then, in the Assist case, the SCSM transits to the **Preparing SSF Instructions** state, and in the Handoff case, the SLPI will be released.
+
+The call-control-related operations relevant to the SCF-SSF interface (except the SCME related operations) are categorized into:
+
+- 1) call-processing-related operations; and
+- 2) non-call-processing-related operations.
+
+Call-processing-related operations are grouped into the following two sets:
+
+- **CollectInformation;**
+  - **AnalyseInformation;**
+  - **SelectFacility;**
+  - **SelectRoute;**
+  - **Connect;**
+  - **Continue.**
+- and
+- **InitiateCallAttempt;**
+  - **ConnectToResource;**
+  - **DisconnectForwardConnection;**
+  - **ReleaseCall;**
+  - **EstablishTemporaryConnection.**
+
+For the first set of call-processing-related operations, the SCF may not send two operations of the same set in a series of TCAP messages or in a component sequence to the SSF, but send them only one at a time. Two operations of the first set shall be separated by at least one EDP-R message received by the SCSM. The same applies for any operation of the first set followed by ConnectToResource or Establish Temporary Connection.
+
+The non-call-processing operations include the rest of the operations at the SCF-SSF interface (but not the SCME related operations). When the service logic needs to send operations in parallel, they are sent in the component sequence.
+
+In what follows, each state is described in a separate subclause together with the events that cause a transition out of this state. The outputs are presented within smaller rectangles than the states are; unlike the states and events, the outputs are not enumerated.
+
+#### 3.1.2.5.1 State 1 – "Idle"
+
+The following events are considered in this state:
+
+- (e1) SL\_Invocation – This is an internal event caused by the need of the service logic to start a call. The SCSM issues the **InitiateCallAttempt** operation to the SSF.
+- (E2) Query\_from\_SSF – This is an external event, caused by a reception of one of the following operations:
+  - **InitialDP;**
+  - **AssistRequestInstructions** (for the Service Handoff case);
+  - **TAnswer;**
+  - **TDisconnect;**
+  - **TermAttemptAuthorized;**
+  - **TMidCall;**
+  - **TNoAnswer;**
+  - **AnalysedInformation;**
+  - **TBusy;**
+  - **CollectedInformation;**
+  - **OAnswer;**
+  - **OCalledPartyBusy;**
+  - **ODisconnect;**
+  - **OMidCall;**
+  - **ONoAnswer;**
+  - **OriginationAttemptAuthorized;** and
+  - **RouteSelectFailure.**
+
+In the case of handoff, the timer  $T_{\text{ASSIST/HANDOFF}}$  is stopped.
+
+Both events cause a transition to State 2, **PreparingSSFInstructions**.
+
+- (E3) **Notification\_from\_SSF** – This is an external event caused by the reception of **InitialIDP** or **TAnswer**, **TDisconnect**, **TermAttemptAuthorized**, **TMidCall**, **TNoAnswer**, **AnalysedInformation**, **TBusy**, **CollectedInformation**, **OAnswer**, **OCalledPartyBusy**, **ODisconnect**, **OMidCall**, **ONoAnswer**, **OriginationAttemptAuthorized**, **RouteSelectFailure** operation that notifies the detection of TDP\_N in the SSF. This event causes a transition back to the same state.
+
+### 3.1.2.5.2 State 2 – "Preparing SSF Instructions"
+
+In this state, the SCF determines how to further process.
+
+The following events are considered in this state:
+
+- (e4) **Processing\_Completed** – This is an internal event. In this case, the SCF has completed the processing of the instructions to the SSF. This event causes a response to be sent to the SSF and a transition to State 1, **Idle**.
+- (e5) **SR\_Facilities\_Needed** – This is an (internal) event caused by the need of the service logic for additional information from the call party; hence is the necessity to set up a connection between the call party and the SRF. This event causes a transition to State 3, **Routing to Resource**.
+- (e6) **Processing\_Failure** – This (internal) event causes an appropriate exception processing and a transition back to State 1, **Idle**.
+
+NOTE – Here and further in this Recommendation, the exception processing is not defined. It is assumed, however, that it has to include releasing all the involved resources and sending an appropriate response message to the SSF.
+
+To further describe the procedures relevant to this state, the state is divided into three sub-states, which are described in the following three subclauses (this subdivision is illustrated in Figure 19).
+
+#### 3.1.2.5.2.1 State 2.1 – "Preparing SSF Instructions"
+
+State 2.1, **Preparing SSF Instructions**, is where the initial decision is made on whether the SDF information or a Specialized Resource is needed, whether queueing is supported, etc. In addition, the EDP-R-related processing is also performed in this state.
+
+On entering this state, the SCSM starts or resets the timer  $T_{SCF-SSF}$ .
+
+The following events are considered in this state:
+
+- (e2.1) **Non-Call\_Processing\_Instructions** – This is an internal event caused by the service logic when there is a need to send such an operation to the SSF. It causes one or more of the following operations to be issued to the SSF:
+  - **ApplyCharging**;
+  - **CallInformationRequest**;
+  - **Cancel (allRequests)**;
+  - **FurnishChargingInformation**;
+  - **RequestReportBCSMEvent**;
+  - **RequestNotificationChargingEvent**;
+  - **ResetTimer**; and
+  - **SendChargingInformation**.
+
+This event causes a transition back to State 2.1, **Preparing SSF Instructions**.
+
+- (e2.2) **SR\_Facilities\_Needed** – This is an internal event, caused by the service logic when there is a need to use the SRF. This event maps into the SCSM event (e5).
+- (e2.3) **Call\_Processing\_Instruction\_Ready** (Monitoring not required) – This is an internal event caused by the service logic when the final call-processing-related operation is ready and there is no armed EDP and no outstanding **CallInformationReport**, **EventNotificationCharging** or **ApplyChargingReport** operation. It causes one of the following operations to be issued to the SSF:
+  - **AnalyseInformation**;
+  - **Connect**;
+  - **Continue**;
+  - **ReleaseCall**;
+  - **SelectFacility**; and
+  - **SelectRoute**.

+
+### 3.1.2.5.2.2 State 2.2 – "Queueing FSM"
+
+When the SCF is processing the query from the SSF-CCF, it may find that the resource to which the call shall be routed is unavailable. One possible reason causing the resource to be unavailable is the "busy" condition.
+
+NOTE – The manner in which the status of the resources is maintained is described in 3.1.2.4.5.
+
+Such a resource may be an individual line or trunk or a customer-defined group of lines or trunks. In the latter case, the word "busy" means that all lines or trunks in the group are occupied; and the word "idle" means that at least one line or trunk in the group is idle.
+
+If the resource is busy, the SCF may put the call on queue and resume it later when the resource is idle. The following operations can be sent in this state:
+
+- **HoldCallInNetwork;**
+- **ApplyCharging;**
+- **CallInformationRequest;**
+- **FurnishChargingInformation;**
+- **RequestReportBCSMEEvent;**
+- **RequestNotificationChargingEvent;**
+- **ResetTimer;** and
+- **SendChargingInformation.**
+
+The following events are considered in this state:
+
+- (e2.10) Queueing\_Processing\_Finished – This is an internal event caused by the SLP when it is ready to prepare the call-related operation to the SSF. This event causes a transition to State 2.1, **Preparing SSF Instructions**.
+- (E2.11) Abort\_from\_SSF – This is an external event caused by the reception of the **Abort** message from the SSF (on call abandonment), and it causes a transition that maps into the SCSM event (e4).
+
+This state further expands into an FSM, which is depicted in Figure 20.

+
+**Partial expansion of the State 2 FSM as related to queueing**
+
+This FSM does not explicitly describe all possible combinations of resource monitoring functions used for queueing. The following possibilities may be used in implementations:
+
+- **RequestFirstStatusMatchReport** by means of SCME;
+- **RequestCurrentStatusChangeReport** by means of the SCME;
+
+- **RequestEveryStatusChangeReport** by means of the SCME; and
+- monitoring based on issuing by the SCSM of the **RequestEventReportBCSM** operation and subsequent reception of the **EventReportBCSM** operation to report the availability of the resource. Both the Request and Report occur in a single different call context. In this case, operations to the SDF or equivalent SCF functionality may be used for scanning the status of resources.
+
+In the rest of this subclause, the state-by-state description of the FSM is followed by the description of the supporting mechanisms of the SCME.
+
+#### 3.1.2.5.2.2.1 State 2.2.1 – "Preparing SSF Instructions"
+
+In this state, the SCSM prepares the instructions for the SSF to complete the call. The following events are considered in this state:
+
+- (e2.2.1) **Instruction\_Ready** – This is an internal event that takes place only when the required resource is available. In this case, the SCSM has obtained the address of the free resource via the **Get\_Resource** method of the RCO (see 3.1.2.4.5). This event causes a transition to the State 2.1, **PreparingSSFInstructions** [transition (e2.10)].
+- (e2.2.2) **Non-Call\_Processing\_Instructions** – This is an internal event caused by the service logic when there is a need to send such an operation to the SSF. It causes one or more of the following operations to be issued to the SSF:
+  - **ApplyCharging;**
+  - **CallInformationRequest;**
+  - **FurnishChargingInformation;**
+  - **RequestReportBCSMEEvent;**
+  - **RequestNotificationChargingEvent;**
+  - **ResetTimer;** and
+  - **SendChargingInformation.**
+This event causes a transition back to State 2.2.1, **Preparing SSF Instructions**.
+- (e2.2.3) **Busy\_Line/Trunk** – This is an internal event caused by the RCO when no terminating line/trunk is available. This event causes the operation, with a suitable queueing timervalue, to be sent to the SSF, and a transition to State 2.2.2, **Queueing**.
+
+#### 3.1.2.5.2.2.2 State 2.2.2 – "Queueing"
+
+In this state, the SCSM is awaiting an indication from the RCO to proceed with routing a call to an idle trunk/line. The support of playing various announcements is also provided when the SCSM is in this state. In this Recommendation, the relevant further expansion of the state is not provided; it is, however, not different from that of the SCSM States 3 and 4. Nevertheless, if announcements are completed before the call is dequeued and the SSF-FSM has transitioned to state **Waiting for Instructions**, the operation should be sent to set the  $T_{SSF}$  with an appropriate value. Once the SCSM enters this state, the Queueing Timer is started, and the  $T_{SCF-SSF}$  is reset. The respective roles of these timers are as follows:
+
+- 1) The Queueing Timer limits the time that a call can spend in the queue, and its value may be customer-specific.
+- 2) The  $T_{SCF-SSF}$  signals when the **ResetTimer** operation shall be sent to the SSF-CCF lest the latter abandons the call. Hence, the value of this timer is set in agreement with that of the relevant timer  $T_{SSF}$  within the SSF-CCF.
+
+The **FurnishChargingInformation** operation may also be sent to the SSF at this time to indicate the initiation of queueing for call logging purposes.
+
+The following events are considered in this state:
+
+- (e2.2.4) **Refresh\_Timer\_Expired** – This is an internal event, which results in sending the **ResetTimer** operation to the SSF-CCF and a transition back to the same state.
+- (e2.2.5) **Idle\_Line/Trunk** – This is an internal event, which maps into the State 2 event (e2.10).
+
+- (e2.2.6) Queueing\_Timer\_Expired – This is an internal event, which results in processing the Cancel method of the RCO and causes a transition out of this state to the State 2.1, **Preparing SSF Instructions** [Transition (e2.10)] [following procedures depends on decision of the service logic that may play (or not play) the terminating announcement].
+- (E2.2.7) Abort\_from\_SSF – This is an external event caused by the reception of the Abort message from the SSF (on call abandonment), and it causes a transition that maps into the State 2 event (E2.11). The Service Control Managing Entity (SCME) takes care of updating the queueing data via the Cancel method of the RCO.
+
+### 3.1.2.5.2.3 State 2.3 – "Waiting for Notification or Request"
+
+In this state, the SCSM waits for a notification or a request from the SSF.
+
+On entering this state the SCSM stops the timer T<sub>SCF-SSF</sub>.
+
+The following events are considered in this state:
+
+- (E2.7) EDP-R – This is an external event, caused by a reception of the following operations:
+  - EventReportBCSM (for EDP\_R);
+  - TAnswer;
+  - TDisconnect;
+  - TermAttemptAuthorized;
+  - TMidCall;
+  - TNoAnswer;
+  - AnalysedInformation;
+  - TBusy;
+  - CollectedInformation;
+  - OAnswer;
+  - OCalledPartyBusy;
+  - ODisconnect;
+  - OMidCall;
+  - ONoAnswer;
+  - OriginationAttemptAuthorized; and
+  - RouteSelectFailure.
+
+This event causes a transition to State 2.1, **Preparing SSF Instructions**.
+
+- (E2.8) Not\_Last\_EDP-N – This is an external event, caused by a reception of one of the following operations:
+  - ApplyChargingReport;
+  - CallInformationReport;
+  - EventReportBCSM (for EDP\_N);
+  - EventNotificationCharging;
+  - TAnswer;
+  - TDisconnect;
+  - TermAttemptAuthorized;
+  - TMidCall;
+  - TNoAnswer;
+  - AnalysedInformation;
+  - TBusy;
+  - CollectedInformation;
+  - OAnswer;
+  - OCalledPartyBusy;
+  - ODisconnect;
+  - OMidCall;
+  - ONoAnswer;
+  - OriginationAttemptAuthorized; and
+  - RouteSelectFailure.
+
+In this case, there is still an outstanding armed EDP or pending **CallInformationReport** or **ApplyChargingReport** operation. This event causes a transition back to State 2.3, **Waiting for Notification or Request**.
+
+- (E2.9) Last\_EDP-N – This is an external event, caused by a reception of one of the following operations:
+  - **ApplyChargingReport**;
+  - **CallInformationReport**;
+  - **EventReportBCSM** (for EDP\_N);
+  - **TAnswer**;
+  - **TDisconnect**;
+  - **TermAttemptAuthorized**;
+  - **TMidCall**;
+  - **TNoAnswer**;
+  - **AnalysedInformation**;
+  - **TBusy**;
+  - **CollectedInformation**;
+  - **OAnswer**;
+  - **OCalledPartyBusy**;
+  - **ODisconnect**;
+  - **OMidCall**;
+  - **ONoAnswer**;
+  - **OriginationAttemptAuthorized**; and
+  - **RouteSelectFailure**.
+
+In this case, there is no outstanding armed EDP and no pending **CallInformationReport** or **ApplyChargingReport**. This event maps into the SCSM event (e4).
+
+- (e2.12) Notification\_or\_Request\_Continuing\_Instruction – This is an internal event caused by the service logic when there is a need to send such an operation to the SSF. It causes one of the following operations to be issued to the SSF:
+  - **RequestReportBCSMEEvent** (for the purpose of which:
+    - i) one or more EDPs will be armed;
+    - ii) some armed EDPs will be disarmed; or
+    - iii) all armed EDPs will be disarmed when there are other pending requests).
+  - **FurnishChargingInformation**;
+  - **ApplyCharging**;
+  - **RequestNotificationChargingEvent**; and
+  - **SendChargingInformation**.
+
+This event causes a transition to State 2.3, **Waiting for Notification or Request**.
+
+- (e2.13) Monitoring\_Cancel\_Instruction – This is an internal event caused by the service logic when there is a need to send this operation to the SSF. It causes the following operation to be issued to the SSF:
+  - **Cancel** (all Requests); and
+  - **RequestReportBCSMEEvent** (for the purpose of which all armed EDPs will be disarmed when there are no more other pending requests).
+
+This event maps into the SCSM event (e4).
+
+- (e2.14) Release\_Call\_Instruction (**CallInformationReport** or **ApplyChargingReport** has been requested) – This is an internal event caused by the service logic when there is a need to send such an operation to the SSF. It causes the following operation to be issued to the SSF:
+  - **ReleaseCall** (when there is an outstanding **CallInformationReport** or **ApplyChargingReport**).
+
+This event causes a transition to State 2.3, **Waiting for Notification or Request**.
+
+- (e2.15) Release\_Call\_Instruction (neither **CallInformationReport** nor **ApplyChargingReport** has been requested) – This is an internal event caused by the service logic when there is a need to send such an operation to the SSF. It causes the following operation to be issued to the SSF:
+  - **ReleaseCall** (when there is no outstanding **CallInformationReport** or **ApplyChargingReport**).
+
+This event maps into the SCSM event (e4).
+
+This concludes the description of State 2, **Preparing SSF Instructions**.
+
+### 3.1.2.5.3 State 3 – "Routing to Resource"
+
+The resource is any SRF facility (e.g. Intelligent Peripheral).
+
+In this state, interactions with the SSF are necessary. Accordingly, the following events cause transitions out of this state:
+
+- (e7) Resource\_Attached – The SRF is available. This event causes a transition to State 4, **User Interaction**;
+- (e8) Handoff\_Needed – When the Handoff procedure is initiated, the SCSM terminates the interaction with the initiating SSF. This event causes a transition to the State 1, **Idle**. When the **AssistRequestInstructions** operation from the Handed-off SSF is received by the SCME-Control, the SCME-Control creates the new SCSM. The SCF shall maintain sufficient information in order to correlate the subsequent **AssistRequestInstructions** operation (from the Handoff SSF) to the existing Service Logic Program Instance (SLPI);
+- (e9) Failure\_from\_SSF – The inability of the SSF to connect to requested resources causes a transition to State 2, **Preparing SSF Instructions**; and
+- (e10) Timer\_Expired – This event takes place when  $T_{\text{ASSIST/HANDOFF}}$  expires. This event causes a transition to State 2, **Preparing SSF Instructions**.
+
+To further describe the procedures relevant to this state, the state is divided into three sub-states, which are described in the following two subclauses (this subdivision is illustrated in Figure 21).
+
+#### 3.1.2.5.3.1 State 3.1 – "Determine Mode"
+
+In this state, the SCSM determines the User Interaction mode to connect the call to SRF. The following events are considered in this state:
+
+- (e3.1) Instruction\_Ready – This is an internal event that takes place only in the Initiating SSF relay case. In this case, the SCSM sends the **ConnectToResource** operation accompanied by **PlayAnnouncement** or **PromptAndCollectUserInfoInformation** operation to the Initiating SSF, and transits out to the State 4, **User Interaction**. This transition maps into the event (e7);
+- (e3.2) Assist\_Needed – This event is an internal event that takes place when the Assisting SSF is needed or Direct SCF-SRF relation is needed. In this case, the SCSM sends the **EstablishTemporaryConnection** operation to the Initiating SSF with the Assisting SSF address or SRF address, and transits to the State 3.2, **WaitingForAssistRequestInstructions**; and
+- (e3.3) Handoff\_Needed – This is an internal event that takes place only in the Handoff case. In this case, the SCSM sends the **Connect** or **SelectRoute** operation with the Handed-off SSF address to the Initiating SSF, sets the  $T_{\text{ASSIST/HANDOFF}}$  timer, and transits to the State 1, **Idle**. This transition maps into the event (e8). The SCF shall maintain sufficient information in order to correlate the subsequent **AssistRequestInstructions** operation (from the handoff SSF) to the existing SLPI.
+
+#### 3.1.2.5.3.2 State 3.2 – "Waiting for Assist Request Instructions"
+
+In this state, the SCSM waits for the **AssistRequestInstructions** operation from the Assisting SSF (SSF relay case) or from the SRF (Direct SCF-SRF case). On entering this state the SCSM starts the Timer  $T_{\text{ASSIST/HANDOFF}}$ , and resets the timer  $T_{\text{SCF-SSF}}$  (if it is used). The following events are considered in this state:
+
+- (E3.4) Assist\_Request\_Instructions\_from\_SSF (Assisting SSF relay case) – This is an external event caused by the receipt of **AssistRequestInstructions** from the Assisting SSF. In this case, the SCSM transmits the **ConnectToResource** operation accompanied by **PlayAnnouncement** or **PromptAndCollectUserInfoInformation** operation to the Assisting SSF, and transits out to the State 4, **User Interaction**. This transition maps into the event (e7);
+- (E3.5) Assist\_Request\_Instructions\_from\_SRF (Direct SCF-SRF case) – This is an external event caused by the receipt of **AssistRequestInstructions** from the SRF. In this case, the SCSM transmits the **PlayAnnouncement** or **PromptAndCollectUserInfoInformation** operation to the SRF, and transits out to the State 4, **User Interaction**. This transition maps into the event (e7);
+
+- (e3.6) Refresh\_Timer\_Expired (OPTIONAL: see the Note in 3.1.2.5) – This is an internal event that takes place on the expiration of  $T_{SCF-SSF}$ . In this case, the SCSM transmits the **ResetTimer** operation to the Initiating SSE, and transits back to the same state;
+- (e3.7) Assist\_Timer\_Expired – This is an internal event that takes place on the expiration of  $T_{ASSIST/HANDOFF}$ . In this case, the SCSM informs the SCME and SLP, and transits to State 2, **Preparing SSF Instructions**, after sending the **DisconnectForwardConnection** operation to the SSF. This event maps into the event (e10); and
+- (E3.8) Initial\_SSF\_Failure – This is an external event caused by the reception of SSF failure. This event causes a transition that maps into the SCSM event (E9).

+
+```
+
+The diagram illustrates the State 3 FSM (Finite State Machine). It begins with entry event (e5) into state '3.1 Determine mode'. From here, three paths exist: (e3.3) 'Hand-off\_Needed' leads to 'Connect/Select\_Route\_to\_SSF' and exits via (e8); (e3.1) 'Instruction\_Ready (SSF relay case)' leads through 'Connect\_to\_Resource\_ind\_to\_SSF' and 'Request\_to\_SRF' to exit (E9); and (e3.2) 'Assist\_Needed' leads through 'Establish\_Temporary\_Connection' to state '3.2 Waiting for assist request instructions'. From state 3.2, several transitions are possible: (e3.6) 'Refresh\_Timer\_Expired' triggers 'Send Reset\_Timer to initiating SSP' and returns to state 3.2; (e3.7) 'Assist\_Timer\_Expired' leads to 'Disconnect\_Forward\_Conn.\_ind\_to\_SSF' and exits via (e10); (E3.8) 'Initial\_SSF\_Failure' exits via (E9); (E3.5) 'Assist\_Request\_Instructions\_from\_SRF (Direct SCF-SRF case)' leads to 'Request\_to\_SRF' and then to state '3. Routing to resource'; and (E3.4) 'Assist\_Request\_Instructions\_from\_SSF (Assisting SSF relay case)' leads through 'Connect\_to\_Resource\_ind\_to\_SSF' and 'Request\_to\_SRF' to state '3. Routing to resource'. State '3. Routing to resource' exits via (e7).

+
+### 3.1.2.5.4 State 4 – "User Interaction"
+
+In this state, the SCF requests the SRF to provide user interaction (e.g. collect additional information and/or play announcements). When an interaction is finished the SCF can instruct the SSF to disconnect the bearer between SSF and SRF. Alternatively, it can send a user interaction operation to the SRF containing an indication that allows the SRF initiated disconnect.
+
+On entering this state the SCSM resets the timer  $T_{SCF-SSF}$  (if it is used).
+
+One event causes a transition out of this state:
+
+- (e11) Continue\_SCF\_Processing – In this case, the SCF has obtained all the information from the SRF, that is needed to instruct the SSF to complete the call. This event causes a transition to State 2, **Preparing SSF Instructions**.
+
+To consider the processing of this state in more detail, it is expanded into a separate FSM depicted in Figure 22A.

+
+#### 3.1.2.5.4.1 State 4.1 – "Waiting for Response from the SRF"
+
+In this state, the SCF waits for the response to the previously sent operation and evaluates this response. The following events are considered in this state:
+
+- (e4.1) More\_Information\_Needed results in issuing yet another operation to the SRF; it causes a transition back to State 4.1;
+- (E4.2) Response\_from\_SRF – This is an external event caused by the reception of **SpecializedResourceReport** or Return Result from **PromptAndCollectUserInformation** operation. On the receipt of this operation, the SCSM transits back to the same state;
+- (E4.2') Final\_Response\_from\_SRF – This is an external event caused by the reception of **SpecializedResourceReport** operation, as requested by the SCF, in response to the previous **PlayAnnouncement** or Return Result from **PromptAndCollectUserInformation** operation with permission of SRF-initiated disconnect. In the Initiating SSF relay case and the Direct SCF-SRF case, on the receipt of this event, the SCSM transits to the State 2, Preparing SSF Instructions. This event maps into the event (*e11*);
+- (e4.3) Continue\_SCF\_Processing – This is an internal event that takes place when the SCSM finishes the User Interaction and requests the disconnection of bearer connection between the Initiating SSF and SRF by means of SCF initiated disconnect. In this case, the SCSM sends the **DisconnectForwardConnection** operation to the Initiating SSF and transits to the State 2, Preparing SSF Instructions. This event maps into the event (*e11*);
+- (e4.3') Continue\_SCF\_Processing – This is an internal event that takes place when the SCSM finishes the User Interaction and requests the disconnection of bearer connection between the Initiating SSF and SRF by means of SRF-initiated disconnect, while an **SpecializedResourceReport** operation is requested to be returned to the SCF in case an announcement is completed. In this case, the SCSM sends the **PlayAnnouncement** (containing a request for returning a **SpecializedResourceReport** operation as an indication of completion of the operation) or **PromptAndCollectUserInformation** operation with permission of SRF-initiated disconnect to the SRF. In the case of Assisting SSF, the SRF-initiated disconnect cannot be used. In this case, the SCSM transits back to the same state;
+- (e4.3'') Continue\_SCF\_Processing – This is an internal event that takes place when the SCSM finishes the User Interaction and requests the disconnection of bearer connection between the Initiating SSF and SRF by means of SRF-initiated disconnect, while no **SpecializedResourceReport** operation is requested to be returned to the SCF in case the announcement is completed. In this case, the SCSM sends the **PlayAnnouncement** operation (not containing a request for returning a **SpecializedResourceReport** operation as an indication of completion of the operation) with permission of SRF-initiated disconnect to the SRF. In the case of Assisting SSF, the SRF-initiated disconnect cannot be used. In this case, the SCSM transits to the State 2, Preparing SSF Instructions. This event maps into the event (*e11*);
+- (E4.5) Failure\_from\_SRF – This is an external event caused by the reception of return error for **PlayAnnouncement** or **PromptAndCollectUserInformation** operation. In this case, the SCSM does not change its state.
+- (e4.6) Refresh\_Timer\_Expired (OPTIONAL: see 3.1.2.5) – This is an internal event that takes place on the expiration of  $T_{SCF-SSF}$ . In this case, the SCSM transmits the **ResetTimer** operation to the Initiating/Assisting SSF, and transits back to the same state; and
+- (e4.7) Cancellation\_Required – This is an internal event that takes place when the SCSM cancels the previous **PlayAnnouncement** or **PromptAndCollectUserInformation** operation. In this case, the SCSM sends the **Cancel** operation to the Assisting SSF (SSF relay case) or the SRF (Direct SCF-SRF case), and transits back to the same state.
+
+It should be noted that the bearer connection between the SSF and the SRF is disconnected when the SCSM exits from this state.
+
+- (e4.8) **Non\_Call\_Processing\_Instructions** – This is an internal event caused by the service logic when there is a need to send this operation to the SSF. It causes one or more of the following operations to be issued to the SSF:
+  - **ApplyCharging;**
+  - **FurnishChargingInformation;**
+  - **RequestNotificationChargingEvent;** and
+  - **SendChargingInformation.**
+
+In this case, the SCSM remains in the same state.
+
+### 3.1.2.5.5 SDF-related states
+
+The interaction with the SDF is possible from any state of the SCF. In the following subclauses, the SDF-related states are specified. The model describes the relationship of one SCF with one SDF. If an SCF needs to access another SDF a new FSM should be instantiated.
+
+In what follows, the states and events are enumerated independent of the rest of the SCSM; the discussion is accompanied by Figure 22B.

+
+FIGURE 22B/Q.1218  
+The SDF-related states
+
+#### 3.1.2.5.5.1 State 1 – "Idle"
+
+This state is a sub-state of any state before a request to the SDF is issued. The following event is considered in this state:
+
+- (e1) **Bind\_Request** – This is an internal event, caused by the need of the service logic to create an association with an SDF in order to begin accessing data. This event causes a transition to the State 2, **Wait for Subsequent Requests**.
+
+#### 3.1.2.5.5.2 State 2 – "Wait for Subsequent Requests"
+
+In this state, subsequent operations to be sent with the **Bind** operation (in the same message) to the SDF are expected. The following two events are considered in this state:
+
+- (e2) **Request\_to\_SDF** – This is an internal event, caused by the reception of an operation. The operation is buffered until the reception of a delimiter (or a timer expiration). The SCSM remains in the same state; and
+- (e3) **Request\_to\_SDF\_with\_Bind** – This is an internal event caused by the reception of a delimiter, that indicates the reception of the last operation to be sent. Once the delimiter is received, a message containing the argument of the **Bind** operation and other operations' arguments, if any, is sent to the SDF. This event causes a transition out of this state to the State 3, **Wait for Bind Result**.
+
+#### 3.1.2.5.5.3 State 3 – "Wait for Bind Result"
+
+In this state, the SCF is waiting for the response from the SDF. Two events are considered in this state:
+
+- (E4) **Bind Error** – This is an external event, caused by the reception of an error to the **Bind** operation previously issued to the SDF. This event causes a transition out of this state to State 1, **Idle**.
+- (E5) **Response\_from\_SDF\_with\_Bind** – This is an external event, caused by the reception of a **Bind** result combined with the responses to other operations previously issued to the SDF (if any). This event causes a transition to State 4, **SDF Bound**.
+
+#### 3.1.2.5.5.4 State 4 – "SDF Bound"
+
+In this state, the SCF has established an authenticated access to the SDF, and is waiting for requests to the SDF from the service logic or is waiting for responses to the operations previously issued to the SDF. Three events are considered in this state:
+
+- (e6) **Request\_to\_SDF** – This is an internal event, caused by the need of the service logic to access data in the SDF. The SCSM remains in the same state;
+- (E7) **Response\_from\_SDF** – This is an external event, caused by the reception of responses to the operations previously issued to the SDF. The SCSM remains in the same state; and
+- (e8) **Unbind\_request** – This is an internal event, caused by the need of the service logic to terminate the authenticated access to the SDF. This event causes a transition state to State 1, **Idle**.
+
+In addition to the above model, an SDL description of SCSM is shown in Annex B.
+
+### 3.1.3 SRF application entity procedures
+
+#### 3.1.3.1 General
+
+This subclause provides the definition of the SRF Application Entity (AE) procedures related to the SRF-SCF interface. The procedures are based on the use of Signalling System No. 7 (SS No. 7); other signalling systems can be used.
+
+Other capabilities may be supported in an implementation-dependent manner in the IP, SSP or SN.
+
+The AE, following the architecture defined in Recommendations Q.700, Q.771 and Q.1400, includes Transaction Capabilities Application Part (TCAP) and one or more ASEs called TC-users. The following subclauses define the TC-user ASE and SACF and MACF rules, which interface with TCAP using the primitives specified in Recommendation Q.771.
+
+The procedure may equally be used with other message-based signalling systems supporting the application layer structures defined.
+
+In case interpretations for the application entity procedures defined in the following differ from detailed procedures and the rules for using TCAP services, the statements and rules contained in the detailed subclauses 3.3 and 3.4 shall be followed.
+
+### 3.1.3.2 Model and interfaces
+
+The functional model of the AE-SRF is shown in Figure 23; the ASEs interface to TCAP (to communicate with the SCF) as well as interface to the maintenance functions. The scope of this Recommendation is limited to the shaded area in Figure 23.
+
+The interfaces shown in Figure 23 use the TC-user ASE primitives specified in Recommendation Q.771 [interface (1)] and N-Primitives specified in Recommendation Q.711 [interface (2)]. The operations and parameters of intelligent network application protocol (INAP) are defined in clause 2.

+
+### 3.1.3.3 Relationship between the SRF-FSM and maintenance functions/bearer connection handling
+
+The primitive interface between the SRF-FSM and the maintenance functions is an internal interface and is not subject for standardization in IN CS-1.
+
+The relationship between the bearer connection handling and the SRF-FSM may be described as follows for the case of a call initiated by the SSF: when a call attempt is initiated by the SSF, an instance of an SRF-FSM is created.
+
+The SRF-FSM handles the interaction with the SCF-FSM and the SSF-FSM.
+
+The management functions related to the execution of operations received from the SCF are executed by the SRF Management Entity (SRME). The SRME interfaces the different SRF Call State Models (SRSM) and the Functional Entity Access Manager (FEAM). Figure 24 shows the SRF-FSM structure.
+
+![Diagram of SRF-FSM structure showing FEAM, SRME, and multiple SRSM components within a dashed boundary labeled SRF-FSM.](1684f5f8c34bd0ef6e933664d88b9d86_img.jpg)
+
+The diagram illustrates the SRF-FSM structure. A dashed rectangular box labeled 'SRF-FSM' contains three main components: FEAM (Functional Entity Access Manager) at the top, SRME (SRF Management Entity) in the center, and multiple SRSM (SRF Call State Model) components at the bottom. FEAM is connected to SSF (Service Switching Function) on the left and SCF (Service Control Function) on the right. FEAM is also connected to SRME. SRME is connected to each of the SRSM components. The SRSM components are arranged horizontally, with three shown and an ellipsis between the second and third. The diagram is labeled 'T1146870-92/d25' at the bottom right.

+**SRF-FSM structure**
+
+The model associates a Finite State Machine (FSM) with each initial interaction request from the SCF. Thus, multiple initial requests may be executed concurrently and asynchronously by the SRF, which explains the need for a single entity that performs the tasks of creation, invocation, and maintenance of the SRSM objects. This entity is called the SRF management entity (SRME). In addition to the above tasks, the SRME maintains the dialogues with the SCF and SSF on behalf of all instances of the SCSM. In particular, the SRME:
+
+- 1) interprets the input messages from other FEs and translates them into corresponding SRSM events; and
+- 2) translates the SRSM outputs into corresponding messages to other FEs.
+
+NOTE – Such a request from the SCF is executed by the SCSM when it is in its State 4.
+
+Finally, the Functional Entity Access Manager (FEAM) relieves the SRME of low-level interface functions. The FEAM functions include:
+
+- 1) establishing and maintaining the interfaces to the SSF and SCF;
+- 2) passing (and queueing when necessary) the messages received from the SSF and SCF to the SRME; and
+- 3) formatting, queueing (when necessary), and sending messages received from the SRME to the SSF and SCF.
+
+### 3.1.3.4 The SRSM
+
+The SRSM is presented in Figure 25. In what follows, each state is described in a separate subclause together with the events that cause a transition out of this state. Finally, the outputs are presented within smaller rectangles than the states are; unlike the states and events, the outputs are not enumerated.

+
+FIGURE 25/Q.1218
+
+### The SRSM
+
+Each state is discussed in the following subclauses. General rules applicable to more than one state are addressed here.
+
+One component or a sequence of components received in one or more TCAP messages may include a single operation or multiple operations, and it is processed as follows:
+
+- The SRSM processes the operations in the order in which they are received.
+
+- The SRSM examines subsequent operations in the sequence. When a Cancel (for PlayAnnouncement or PromptAndCollectUserInfo) operation is encountered in the sequence in state user interaction, it executes it immediately. In all other cases, the SRSM queues the operations and awaits an event (such an event would be the completion of the operation being executed, or reception of an external event).
+- If there is an error in processing one of the operations in the sequence, the SRF-FSM processes the error (see below) and discards all remaining operations in the sequence.
+- If an operation is not understood or is out of context (i.e. it violates the SACF rules defined by the SRSM) as described above, the SRF-FSM processes the error according to the rules given in 3.4.2 (using TC U-REJECT or the operation error UnexpectedComponentSequence).
+
+In any state, if there is an error in a received operation, the maintenance functions are informed. Generally, the SRSM remains in the same state in which it received the erroneous operations, however different error treatment is possible in specific cases as described in 3.2; depending on the class of the operation, the error could be reported by the SRF to the SCF using the appropriate component (see Recommendation Q.774).
+
+In any state, if the dialogue with the SCF (direct SCF-SRF case) is terminated, then the SRSM returns to idle state after ensuring that all resources allocated to the dialogues have been de-allocated. The SRF shall remain connected to the SSF as long as it has PlayAnnouncement operations active or buffered. The resources allocated to the call will be de-allocated when all announcements are completed or when the SSF disconnects the bearer connection (i.e. call party release).
+
+In any state (except idle), if the SSF disconnects the bearer connection to the SRF before the SRF completes the user interaction, then the SRSM clears the call and ensures that all SRF resources allocated to the call have been de-allocated. Then it transits to the idle state.
+
+The SRSM has an application timer,  $T_{\text{SRF}}$ , whose purpose is to prevent excessive call suspension time. This timer is set when the SRF sends Setup Response bearer message to the SSF (SSF relay case) or the AssistRequestInstructions operation (Direct SCF-SRF case). This timer is stopped when a request is received from the SCF. The SRF may reset  $T_{\text{SRF}}$  on transmission of the SpecializedResourceReport operation or the return result for the PromptAndCollectUserInfo operation when there is no queued user interaction operation. On the expiration of  $T_{\text{SRF}}$ , the SRSM transits to the idle state ensuring that all SRF resources allocated to the call have been de-allocated.
+
+#### 3.1.3.4.1 State 1 – “Idle”
+
+The idle state represents the condition prior to, or at the completion of, an instance of user interaction. This state is entered as a result of events E3, e4, E10, e11 and e12. It is exited as a result of event E1.
+
+- (E1) Connect\_Request\_from\_SSF – This event corresponds to a bearer signalling connection request message from the SSF. The details of the bearer signalling state machine related to establishing the connection are not of interest to the FSM. The SRSM goes to state “Connected”;
+- (E3) Connection\_Released\_from\_SSF – This event takes place when the SRSM receives a release message from the SSF in connected state. The SRSM goes to state “Idle”;
+- (e4) SRF\_Sanity\_Timeout – This event occurs when the SRSM has been in connected state for a network-operator-defined period of time (timer  $T_{\text{SRF}}$ ) without having a PlayAnnouncement/PromptAndCollectUserInfo operation to execute. The SRF initiates a bearer channel disconnect sequence to the SSF using the applicable bearer channel signalling system. The SRSM goes to state “Idle”;
+- (E10) Connection\_Released\_from\_SSF – This event takes place when the SRSM receives a release message from the SSF in user interaction state. The SRSM goes to state “Idle”;
+
+- (e11) `Disconnect_to_SSF` – This event occurs when the SCF has enabled SRF initiated disconnect by the last `PlayAnnouncement/PromptAndCollectUserInfoInformation` from SCF (E2) or (E5) with the parameter `disconnectFromIPForbidden`. The SRSM initiates a bearer channel disconnect sequence to the SSF using the applicable bearer channel signalling system after sending the last `SpecializedResourceReport` operation to the SCF (e7). The SRSM goes to state “Idle”; and
+- (e12) `SRF_Sanity_Timeout` – This event occurs when the SRSM has been in User interaction state for a network-operator-defined period of time (timer  $T_{\text{SRF}}$ ) without having a `PlayAnnouncement/PromptAndCollectUserInfoInformation` operation to execute. The SRF initiates a bearer channel disconnect sequence to the SSF using the applicable bearer channel signalling system. The SRSM goes to state “Idle”.
+
+#### 3.1.3.4.2 State 2 – “Connected”
+
+This state represents the condition of the SRSM when a bearer channel has been established between a user and the SRF but the initial `PlayAnnouncement/PromptAndCollectUserInfoInformation` has not yet been received (e.g. when `EstablishTemporaryConnection` procedures are used). The method used to provide this bearer channel is not of interest in the FSM.
+
+- (E1) `Connect_Request_from_SSF` – This event corresponds to a bearer signalling connection request message from the SSF in the Idle state. The details of the bearer signalling state machine related to establishing the connection are not of interest in the SRF-FSM. The SRSM goes to state “Connected”.
+- (E2) `PlayAnnouncement/PromptAndCollectUserInfoInformation_from_SCF` – This event takes place when the first `PlayAnnouncement` or `PromptAndCollectUserInfoInformation` operation(s) from the SCF is received. The SRSM goes to state “User interaction”.
+- (E3) `Connection_Released_from_SSF` – This event takes place when the SRF receives a release message from the SSF. The SRSM goes to state “Idle”.
+- (e4) `SRF_Sanity_Timeout` – This event occurs when the SRSM has been connected for a network-operator-defined period of time (timer  $T_{\text{SRF}}$ ) without having a `PlayAnnouncement/PromptAndCollectUserInfoInformation` operation to execute. The SRSM initiates a bearer channel disconnect sequence to the SSF using the applicable bearer channel signalling system. The SRSM goes to state “Idle”.
+- (e5) `Assist_Request_Instructions_Needed` – This event occurs when the `AssistRequestInstructions` operation is sent from the SRSM to the SCF in the absence of a `PlayAnnouncement/PromptAndCollectUserInfoInformation` event (E2) initiated by the presence of a `PlayAnnouncement/PromptAndCollectUserInfoInformation` operation concatenated with the setup request from SSF (E1) (Direct SCF-SRF case). No state change occurs as a result of this event.
+
+#### 3.1.3.4.3 State 3 – “User interaction”
+
+The User interaction state indicates that communication is occurring between the user and the SRF via the bearer channel established at the Connected state. This state is entered as a result of event E2. It is exited as a result of events E10, e11 and e12. Events E5, E6, e7, e8 and e9 do not cause a state change. Event E5 also represents additional `PlayAnnouncement/PromptAndCollectUserInfoInformation` operations which are buffered as discussed in the procedures.
+
+- (E2) and (E5) `PlayAnnouncement/PromptAndCollectUserInfoInformation_from_SCF` – This event takes place when an initial or subsequent `PlayAnnouncement` or `PromptAndCollectUserInfoInformation` operation(s) from the SCF is received. The SRSM goes to state “User interaction” on the first (E2). The SRSM remains in state “User interaction” for subsequent (E5)s.
+- (E6) `Cancel_from_SCF` (for `PlayAnnouncement/PromptAndCollectUserInfoInformation`) – This event takes place when the corresponding `PlayAnnouncement` or `PromptAndCollectUserInfoInformation` operation is received from the SCF. The indicated interaction is terminated if it is presently running, otherwise it is deleted from the buffer. The SRSM remains in state “User interaction”.
+
+- (e7) SRF\_Report\_to\_SCF – This event takes place when a SpecializedResourceReport or a return result for PromptAndCollectUserInformation operation is sent to the SCF. The SRSM remains in state “User interaction”.
+- (e8) PlayAnnouncement/PromptAndCollectUserInformation\_Cancelled\_to\_SCF – This event takes place when the PlayAnnouncement/PromptAndCollectUserInformation error caused by the Cancel (for PlayAnnouncement or PromptAndCollectUserInformation) operation is sent to the SCF. This event represents the successful cancellation of an active or buffered PlayAnnouncement/PromptAndCollectUserInformation operation. The SRSM remains in state “User interaction”.
+- (e9) Cancel\_Error\_to\_SCF – This event takes place when the cancel error (for PlayAnnouncement or PromptAndCollectUserInformation) is sent to the SCF. This event represents the unsuccessful cancellation of a PlayAnnouncement/PromptAndCollectUserInformation operation. The SRSM remains in state “User interaction”.
+- (E10) Connection\_Released\_from\_SSF – This event takes place when the SRSM receives a release message from the SSF. The SRSM goes to state “Idle”.
+- (e11) Disconnect\_to\_SSF – This event occurs when the SCF has enabled SRF initiated disconnect with the last PlayAnnouncement/PromptAndCollectUserInformation from SCF (E2) or (E5). The SRSM initiates a bearer channel disconnect sequence to the SSF using the applicable bearer channel signalling system after sending the last SpecializedResourceReport or a return result for PromptAndCollectUserInformation operation to the SCF. The SRSM goes to state “Idle”.
+- (e12) SRF\_Sanity\_Timeout – This event occurs when the SRSM has been in user interaction state for a network-operator-defined-period of time (timer T<sub>SRF</sub>) without having a PlayAnnouncement/PromptAndCollectUserInformation operation to execute. The SRSM initiates a bearer channel disconnect sequence to the SSF using the applicable bearer channel signalling system. The SRSM goes to state “Idle”.
+
+In addition to these explicitly marked transitions, failure of a user-SRF bearer connection will cause the SRSM to transit to Idle from any state. These transitions are not shown on Figure 25 for the purpose of visual clarity.
+
+### 3.1.3.5 Example SRF control procedures
+
+This subclause provides a detailed description of the SRF procedures. Arrow diagrams are used for the description of the connect, interaction with the end user, and disconnect stages.
+
+The SRF control procedures are based on various physical allocation patterns of SRF. The various control procedures are described in this subclause in accordance with the example physical scenarios of protocol architecture in 0.2.
+
+The service assist and handoff procedures based on the physical scenarios are also described in this subclause as examples.
+
+Note that, through this subclause, bearer connection control signalling messages are used for explanatory purpose, and are not subject for standardization in this Recommendation. The terms used for bearer connection control signalling messages only represent the functional meaning.
+
+#### 3.1.3.5.1 SRF connect procedures
+
+##### 3.1.3.5.1.1 SRF connect physical procedures
+
+Several procedures are required for different physical scenarios. The cases to be covered are described below and illustrated in Figure 26:
+
+- the IP is integrated into the SSP, or directly attached to the SSP, that is interacting with the SCP but the SCP’s operations to the IP are relayed via the SSP which performs any needed protocol conversion;
+- the IP is directly attached to the SSP that is interacting with the SCP but the SCP’s operations to the IP are sent directly to the IP without SSP relaying involved;
+
+- iii) the IP is integrated into another SSP, or directly attached to another SSP, than the one that is interacting with the SCP but the SCP's operations to the IP are relayed via the second SSP (called the "Assist" method), and on completion of the user interaction, control is returned to the first SSP;
+- iv) the IP is directly attached to a node other than the SSP that is interacting with the SCP but the SCP's operations to the IP are sent directly to the IP without SSP relaying involved (called the "Assist" method, but with a variation on the physical connectivity of the entities involved), and on completion of the user interaction, control is returned to the first SSP; and
+- v) the IP is attached to another SSP and on completion of the user interaction, control of the call is retained at that SSP (called the "Handoff" approach).
+
+In each of the above cases, the operations between the SCP and the SSP may be SS No. 7 TCAP-based; the messaging between the SSP and the IP when the SSP does relaying may be DSS 1 using the facility IE (in this case, the SSP would have to do protocol conversion from SS No. 7 TCAP to DSS-1 facility IE for the operations and responses it relayed between the SCP and the IP); the direct messaging between the SCP and the IP may be SS No. 7 TCAP based; and bearer control signalling may be any system.
+
+Each of the scenarios will now be examined using arrow diagrams.
+
+Case i) is illustrated in Figure 27. Note that for the integrated IP/SSP, the internal activities of the node can still be modelled in this way, but the details of how this is achieved are left to the implementor. This approach makes it unnecessary for the SCP to distinguish between integrated and external but directly connected IPs. See also a note on the possibility of concatenating the first user interaction operation with the `ConnectToResource` operation discussed in the subclause on user interaction below. The establishment of the SCF-SRF relationship in this case is implicit.
+
+Case ii) requires that the IP indicate to the SCP that it is ready to receive operations (see Figure 28). The establishment of the SCF-SRF relationship is explicit. Note that it is necessary to convey a correlation ID to ensure that the transaction established between the SCP and the IP can be correlated to the bearer connection set-up as a result of the SCP's preceding operation to the SSP.
+
+Case iii) requires that a transaction be opened with the assisting SSP so that it may relay operations from the SCP to the IP (integrated or external). Once the bearer control signalling has reached the assisting SSP, it triggers on the identity of the called facility, and initiates an interaction with the SCP that has requested the assistance. It would also be possible to trigger on other IEs such as the incoming address. The bearer control signalling must contain information to identify the SCP requesting the assistance, and a correlation ID. This information may be hidden in the address information in such a way that non-message based signalling systems may also be used to establish the bearer connection to the assisting SSP. After the `AssistRequestInstructions` are received by the SCP, the procedures are the same as in case i). Figure 29 illustrates the preamble involved.
+
+Case iv) does not require the establishment of a second transaction from the assisting exchange, hence it need not be an SSP. This then becomes a preamble to the procedure shown in Figure 28 as shown in Figure 30.
+
+Case v) merely requires the sending of an operation to the first SSP to route the call to the handed-off SSP, and then Figure 27 applies at handed-off SSP. This is shown in Figure 31. Note that the activity at handed-off SSP represents a new interaction with the SCP and "`AssistRequestInstructions`" is used. Once the bearer control signalling has reached the assisting SSP, it triggers on the identity of the called facility, and initiates an interaction with the SCP that has requested the assistance. It would also be possible to trigger on other IEs such as the incoming address. The bearer control signalling must contain information to identify the SCP requesting the assistance, and a correlation ID. This information may be hidden in the address information in such a way that non-message based signalling systems may also be used to establish the bearer connection to the assisting SSP.

+- a combination of the above; and

+**3.1.3.5.3 SRF disconnection procedures**
+
+The disconnection procedures are controlled by the SCF and the procedure used is selected based on the needs of the service being executed. The bearer disconnection procedure selected by the SCF is to either allow the SRF to disconnect on completion of user interaction, or to have the SCF explicitly order the SSF to disconnect.
+
+SRF disconnect does not cause disconnection by the SSF-CCF back to the end user terminal unless the transaction with the SCF has been terminated, indicating the user interaction completed the call. The SSF-CCF recognizes that a connection to an SRF is involved because the operations from the SCF for this purpose are distinct from the operations that would be used to route the call towards a destination. There is no impact on bearer signalling state machines as a result of this since incoming and outgoing bearer signalling events are not simply transferred to each other, but rather are absorbed in call processing, and regenerated as needed by call processing. Therefore, to achieve the desired functionality, call processing need simply choose not to regenerate the disconnect in the backward direction. Figure 34 illustrates this concept.
+
+As for the SRF connection procedures, the SRF disconnection is affected by the physical network configuration.

+
+In order to simplify the interface between the SCF and the SRF, a number of assumptions are made. The assumptions, and the resulting rules, result in unambiguous procedures from both the SCF and the SRF points of view. The rules, presented below, refer to the SRF originated disconnect, or “SRF Initiated Disconnect”, and to the SCF originated disconnect, or “SCF Initiated Disconnect”. While other scenarios are possible, they are not included because they either duplicate the functionality presented below or they otherwise do not add value from a service perspective.
+
+- 1) If a series of PlayAnnouncement/PromptAndCollectUserInformation operations are to be executed by the same SRF, then SRF disconnect is inhibited for all but the last and may be inhibited on the last PlayAnnouncement/PromptAndCollectUserInformation. When a subsequent PlayAnnouncement/PromptAndCollectUserInformation is received, it is buffered until the completion of any preceding PlayAnnouncement/PromptAndCollectUserInformation.
+- 2) A generic cancel operation terminates the indicated PlayAnnouncement/PromptAndCollectUserInformation if it is being executed by the SRF, but does not disconnect the SRF. If the cancel operation is for a buffered PlayAnnouncement/PromptAndCollectUserInformation, that PlayAnnouncement/PromptAndCollectUserInformation is discarded, but the current and any buffered PlayAnnouncement/PromptAndCollectUserInformations are executed. An SRF interacts with one user only and therefore cancelling a PlayAnnouncement/PromptAndCollectUserInformation only affects the user to which the SRF is connected.
+- 3) The SCF must either explicitly order “Disconnect” or enable SRF initiated disconnect at the end of the PlayAnnouncement/PromptAndCollectUserInformation. An SRF left connected without a PlayAnnouncement/PromptAndCollectUserInformation to execute may autonomously disconnect if it has not received any PlayAnnouncement/PromptAndCollectUserInformation operations within a defined time limit. This could occur, for example, after an EstablishTemporaryConnection which is not followed within a reasonable time period with a PlayAnnouncement/PromptAndCollectUserInformation operation. This sanity timing value will depend on the nature of the interaction the SRF supports and should be selected by the network operator accordingly.
+- 4) When SRF initiated disconnect is enabled in a PlayAnnouncement/PromptAndCollectUserInformation, then the SRF must disconnect on completion of the user interaction.
+- 5) When SRF initiated disconnect is not enabled, the SCF must ask the SRF to inform it of the completion of the user interaction using the SpecializedResourceReport operation for “announcement complete” or using the return result for the PromptAndCollectUserInformation operation.
+
+- 6) If the user disconnects, the SRF is disconnected and the SSF releases resources and handles the transaction between the SSF and the SCF as specified in Recommendation Q.1214 and in this Recommendation. The SRF discards any buffered operations and returns its resources to idle. The relationship with the SCF is terminated.
+- 7) When the SCF explicitly orders the SSF to disconnect by “DisconnectForwardConnection” operation, the SSF releases the bearer connection to the SRF, and returns to the “waiting for instructions” state. No operation reporting SRF disconnect from the SSF to the SCF is required.
+
+### 3.1.3.5.3.1 SRF initiated disconnect
+
+The SRF disconnect procedure is illustrated in Figure 35. The SRF disconnect is enabled by the SCF within a PlayAnnouncement/PromptAndCollectUserInformation operation. When the SRF receives a PlayAnnouncement/PromptAndCollectUserInformation enabling disconnection, it completes the dialogue as instructed by the PlayAnnouncement/PromptAndCollectUserInformation, and then initiates the SRF initiated disconnection using the applicable bearer control signalling. The SSF-CCF knows that it is an SRF disconnecting and does not continue clearing the call toward the end user. The SSF returns to the “waiting for instructions” state and executes any buffered operations. In the handoff case, the SSP shown in Figure 35 is the “handed-off” SSP.

+
+For the assisting SSF case, the SRF initiated disconnect procedures are not used because the assisting SSF remains in the “waiting for instructions” state and does not propagate the disconnection of the bearer connection to the Initiating SSF. The SCF initiated disconnect procedures described in the following subclause are used for the assisting SSF case.
+
+For the direct SCF-SRF case, the procedures also work in the same manner. The SRF disconnect is enabled by the SCF within a PlayAnnouncement/PromptAndCollectUserInformation operation. When the SRF receives a PlayAnnouncement/PromptAndCollectUserInformation enabling disconnection, it completes the dialogue as instructed by the PlayAnnouncement/PromptAndCollectUserInformation, and then initiates the SRF initiated disconnection using the applicable bearer control signalling. The Initiating SSF-CCF knows that it is an SRF disconnecting and does not continue clearing the call toward the end user.

+**SCF initiated disconnect for assist scenario**
+
+The SCF initiated disconnect uses an operation called `DisconnectForwardConnection`. Once the `DisconnectForwardConnection` is received by the SSF, it will initiate a “release of bearer channel connection” between the physical entities containing the SSF and SRF, using applicable bearer control signalling. Since the SCF (which initiates the disconnect), the SSF (which instructs bearer signalling to disconnect) and the SRF (which receives disconnect notification via bearer signalling) are aware that disconnect is occurring, they are synchronized. Therefore, a “pre-arranged” end may be used to close the transaction. This does not preclude the use of explicit end messages for this purpose.
+
+For assisting SSF case, the initiating SSP, on receipt of the `DisconnectForwardConnection` from the SCP, disconnects forward to the assisting SSP, and this disconnection is propagated to the IP. The initiating SSP, knowing that the forward connection was initiated as the result of an `EstablishTemporaryConnection`, does not disconnect back to the user but returns to the “waiting for instructions” state.
+
+### 3.1.3.5.4 Examples illustrating complete user interaction sequences

+The following figures and their accompanying tables provide examples of complete sequences of user interaction operations covering the three stages:

+
+In some cases, the IP may have an SS No. 7 or other interface to the controlling SCP. This case is shown in Figure 39. Note that the SCP must correlate two transactions to coordinate the activities.

+
+The assisting SSF scenario involves straightforward procedural extensions to the basic cases shown above. One mapping of the assisting SSF case is shown in Figure 40. In this case, SRF initiated disconnect cannot be used. Other physical mappings can be derived as described in the text following the figure and its accompanying table.

+**SSP assist (relay SSP)**
+
+Note that the integrated SRF and SSF relay case requires a transaction between the SCP and the assisting SSP (see Figure 40) but the SCP direct case does not since the transaction is directly between the SCP and the IP connected to the remote exchange. In the latter case, any transit exchanges, including the one the IP (SRF) is connected to, are transparent to the procedures.
+
+Note also that the SCP must again correlate two transactions.
+

+
+Note that the assisting SSP case shown in Figure 40 can be generalized to cover both the case where the SRF is embedded in assisting SSP (as shown), and the case where the SRF is locally connected to assisting SSP. In this latter case, the SRF communication (protocol flows B, C, G and H) would conform to the physical scenario shown in Figure 38.
+
+The service handoff scenario can similarly be viewed as a sequence consisting of an IN service to route a call from one SSP to another, followed by any one of the previously described physical user interaction scenarios. For describing this scenario Figure 40 can be used also.
+
+#### 3.1.3.5.4.1 Message sequences for service assist
+
+The following subclause provides additional details on the message sequences for the service assist procedure in Figure 40:
+
+- 1) The SCP, during the processing of a request for instruction, determines that resources remote from the initiating SSP are required and that call processing will continue from the initiating SSP after the remote resources have been used (e.g. the call will be completed to a destination address after information is collected from the calling party). An EstablishTemporaryConnection operation containing the address of the assisting SSP (for routing the call), the ScfID and the CorrelationID (both used for the assisting SSP to establish communication back to the SCP) is sent to the initiating SSP. The EstablishTemporaryConnection is used instead of a regular Connect operation because of the nature of the connection to the assisting SSP. The initiating SSP must be aware that the SCP will ask it to continue in the processing of the call at some point in the future.
+
+NOTE 1 – The ScfID and CorrelationID may be included in the routing address of the assisting SSP.
+
+*Protocol Flow A*
+
+- 2) The initiating SSP routes the call to the assisting SSP. The ScfID and CorrelationID are sent to the assisting SSP. Existing in-band signalling and SS No. 7 information elements (e.g. routing number) could be used to transport this information. The transport mechanism used to send this information between SSPs is independent of the service assist control procedures between the SCF and SSF.
+
+*Protocol Flow E*
+
+- 3) The assisting SSP uses an AssistRequestInstructions operation to establish communication with the SCP. The CorrelationID is sent in the AssistRequestInstructions to allow the SCP to correlate two transactions.
+
+*Protocol Flow C*
+
+- 4) The SCP sends instructions to the assisting SSP based on service logic control.
+
+*Protocol Flow B*
+
+- 5) The SCP may need to generate reset timer events to the initiating SSP so that it does not time out the call.
+
+*Protocol Flow A*
+
+NOTE 2 – The usage of ResetTimer operation is optional.
+
+- 6) When resource functions have been completed, a DisconnectForwardConnection operation is sent to the initiating SSP. This indicates, that the temporary connection to the assisting SSP has to be disconnected.
+
+*Protocol Flow A*
+
+- 7) The initiating SSP sends a message via bearer control signalling to the assisting SSP to close the "assist" transaction.
+
+*Protocol Flow E*
+
+- 8) The call control returns to the initiating SSP.
+
+#### **3.1.3.5.4.2 Message sequences for handoff**
+
+The following subclause outlines message sequences for the handoff procedure using the protocol flows shown in Figure 40:
+
+- 1) The SCP, during the processing of a request for instruction, determines that resources remote from the initiating SSP are required and that call processing need not continue from the initiating SSP after the remote resources have been used (e.g. a terminating announcement will be played). A Connect operation containing the address of the assisting SSP (for routing the call), the ScfID and the CorrelationID (both used for the assisting SSP to establish communication back to the SCP) is sent to the initiating SSP.
+
+NOTE – The ScfID and CorrelationID may be included in the routing address of the assisting SSP.
+
+*Protocol Flow A*
+
+- 2) The initiating SSP routes the call to the assisting SSP. The ScfID and CorrelationID are sent to the assisting SSP. Existing in-band signalling and SS No. 7 information elements (e.g. routing number) could be used to transport this information. The transport mechanism used to send this information between SSPs is independent of the service assist control procedures between the SCF and SSF.
+
+*Protocol Flow E*
+
+- 3) The assisting SSP uses an AssistRequestInstructions operation to establish communication with the SCP. The CorrelationID is sent in the AssistRequestInstructions to allow the SCP to correlate two transactions. The AssistRequestInstructions is used instead of a regular request instruction (InitialDP or DP-specific operation) because the SCP must associate the AssistRequestInstructions from the assisting SSP-IP with an already active dialogue the SCP has with another SSP.
+
+#### *Protocol Flow C*
+
+- 4) The SCP sends instructions to the assisting SSP based on service logic control.
+
+#### *Protocol Flow B*
+
+- 5) The call control remains at the assisting SSP.
+
+The same service assist and handoff procedures can be reused for a direct link to an IP in this and future capability sets.
+
+### **3.1.4 SDF application entity procedures**
+
+#### **3.1.4.1 General**
+
+This subclause provides the definition of the SDF Application Entity (AE) procedures related to the SDF-SCF interface. The procedures are based on the use of Signalling System No. 7 (SS No. 7).
+
+Other capabilities may be supported in an implementation-dependent manner in the SCP, SDP, SSP, AD or SN.
+
+The AE, following the architecture defined in Recommendations Q.700, Q.771 and Q.1400, includes Transaction Capabilities Application Part (TCAP) and one or more ASEs called TC-users, which are based on the Directory (X.500-Series Recommendations). The following subclauses define the TC-user ASE and SACF & MACF rules, which interface with TCAP using the primitives specified in Recommendation Q.771.
+
+The procedure may equally be used with other signalling message transport systems supporting the application layer structures defined.
+
+In case interpretations for the application entity procedures defined in the following differ from detailed procedures and the rules for using of TCAP service, the statements and rules contained in the detailed subclauses 3.3 and 2.2.2.2 shall be followed.
+
+#### **3.1.4.2 Model and interfaces**
+
+The functional model of the AE-SDF is shown in Figure 41; the ASEs interface to TCAP to communicate with the SCF, and interface to the maintenance functions. The scope of this Recommendation is limited to the shaded area in Figure 41.
+
+The interfaces shown in Figure 41 use the TC-user ASE primitives specified in Recommendation Q.771 [interface 1)] and N-Primitives specified in Recommendation Q.711 [interface 2)]. The operations and parameters of Intelligent Network Application Protocol (INAP) are defined in clause 2.
+
+An instance of SDF-FSM may be created if IN call handling is received from the SCF.
+
+The SDF-FSM handles the interaction with the SCF-FSM.
+
+#### **3.1.4.3 Relationship between the SDF-FSM and the maintenance function**
+
+The primitive interface between the SDF-FSM and the maintenance functions is an internal interface and is not subject for standardization in IN CS-1.
+
+#### **3.1.4.4 SDF state transition model**
+
+As far as IN CS-1 is concerned, the SDF's job is to (synchronously) respond to every request from the SCF after the Bind procedure. The respective Finite State Machine (FSM) is depicted in Figure 42.
+
+Each state is discussed in one of the following subclauses.
+
+General rules applicable to more than one state are as follows:
+
+In any state, if the dialogue with the SCF is terminated, then the SDF-FSM returns to **Idle** state after ensuring that any resources allocated to the call have been de-allocated.

+The SDF-FSM
+
+#### 3.1.4.4.1 State 1 – "Idle"
+
+The only event accepted in this state is:
+
+- (E1) Bind\_from\_SCF – This is an external event caused by the reception of Bind operation from the SCF. This event causes a transition out of this state to State 2, **Bind Pending**.
+
+#### 3.1.4.4.2 State 2 – "Bind Pending"
+
+In this state, a Bind request has been received from the SCF. The SDF is performing the SCF access control procedures behind the Bind operation (e.g. access authentication). There may also be a case such that the Bind operation is a dummy one. Then, the access authentication is not required. Three events are considered in this state:
+
+- (e2) Bind\_Error – This is an internal event, caused by the failure of the Bind operation previously issued to the SDF. This event causes a transition out of this state to State 1, **Idle** and a Bind error is returned to the invoking SCF;
+- (E3) Request\_from\_SCF – This is an external event, caused by the reception of operations before the result from the Bind operation is determined. The SDSM remains in the same state; and
+- (e4) Bind\_Successful – This is an internal event, caused by the successful completion of the Bind operation previously issued to the SDF. This event causes a transition out of this state to State 3, **SCF Bound**.
+
+#### 3.1.4.4.3 State 3 – "SCF Bound"
+
+In this state, the access of the SCF to the SDF was authorized and operations coming from the SCF are accepted. Besides waiting for requests from the SCF, the SDF can send in that state responses to previously issued operations. Three events are considered in this state:
+
+- (E5) Unbind\_from\_SCF – This is an external event, caused by the reception of the Unbind operation from the SCF. The SCF-SDF association is ended and all associated resources are released. This event causes a transition out of this state to State 1, **Idle**;
+
+- (e6) Response\_to\_SCF – This is an internal event, caused by the completion of the operations previously issued by the SCF. Responses are sent to the SCF. The SDSM remains in the same state; and
+- (E7) Request\_from\_SCF – This is an external event, caused by the reception of a request from the SCF to the SDF. The SDSM remains in the same state.
+
+In addition to this finite state machine, an SDL description of SDSM is shown in the Annex B.

+## 3.2 Error procedures
+
+This subclause defines the generic error procedures for the IN CS-1 INAP. The error procedure descriptions have been divided in two subclauses, 3.2.1 listing the errors related to INAP operations and 3.2.2 listing the errors related to error conditions in the different FEs which are not directly related to the INAP operations.
+
+### 3.2.1 Operation related error procedures
+
+The following subclauses define the generic error handling for the operation related errors. The errors are defined as operation errors in 2.1.2. The TCAP services which are used for reporting operation errors are described in 3.4.
+
+Errors which have a specific procedure for an operation are described in 3.3 with the detailed procedure of the related operation.
+
+All errors, which can be detected by the ASN.1 decoder, already may be detected during the decoding of the TCAP message and indicated by the TC error indication "MistypedParameter" in the TC-U-Reject.

+|----------------|--------------|-----------|
+| Precondition:  | SCSM state 4 | SDF Bound |
+| Postcondition: | SCSM state 4 | SDF Bound |
+
+Error Procedure is dependent on the Service Logic. If the SCF is able to change the request, it can do another SDF query, otherwise the service processing should be terminated.

+|----------------|-----------------|-----------|
+| Precondition:  | SDF-FSM state 3 | SCF Bound |
+| Postcondition: | SDF-FSM state 3 | SCF Bound |
+
+The SDF could not perform the operation due to an attribute problem and therefore sends an Attribute error to the SCF. After returning the error, no further error treatment is performed.

+### 3.2.1.2 Cancelled
+
+#### 3.2.1.2.1 General description
+
+##### 3.2.1.2.1.1 Error description
+
+The Error "Cancelled" gives an indication to the SCF that the cancellation, as it was requested by the SCF, of a specific Operation, has been successful. The SCF is only able to cancel certain predefined SCF-->SRF Operations.
+
+##### 3.2.1.2.2 Operations SCF->SRF

+| Precondition:  | SCSM state 4.1 | Waiting for Response from the SRF. |
+| Postcondition: | SCSM state 4.1 | Waiting for Response from the SRF. |
+
+The SCF sends a Cancel after a Play Announcement or PromptAndCollectUserInfoInformation has been sent. The SCF remains in the same state.
+
+#### B) Receiving Cancelled Error
+
+|                |                |                          |
+|----------------|----------------|--------------------------|
+| Precondition:  | SCSM state any | Service Logic dependent. |
+| Postcondition: | SCSM state any | Service Logic dependent. |
+
+After sending a Cancel operation the Service Logic may continue (e.g. sending more PlayAnnouncement or PromptAndCollectUserInfoInformation or a DisconnectForwardConnection). The Cancelled Error can therefore be received in any state. The treatment is Service Logic dependent.
+
+### Procedures at Responding Entity (SRF)

+|----------------|--------------|-------------------|
+| Precondition:  | SRSM state 3 | User Interaction. |
+| Postcondition: | SRSM state 3 | User Interaction. |
+
+The indicated PlayAnnouncement or PromptAndCollectUserInfoInformation is terminated if it is presently executing or deleted from the buffer. If the indicated PlayAnnouncement or PromptAndCollectUserInfoInformation is already executed this causes a failure ("CancelFailed").
+
+#### B) Sending Cancel Error
+
+|                |              |                   |
+|----------------|--------------|-------------------|
+| Precondition:  | SRSM state 3 | User Interaction. |
+| Postcondition: | SRSM state 3 | User Interaction. |
+
+After returning the "Cancelled" Error the SRF stays in the same state. The execution of the indicated PlayAnnouncement or PromptAndCollectUserInfoInformation is aborted, i.e. the SRF remains connected and the next PlayAnnouncement or PromptAndCollectUserInfoInformation is executed if available.
+
+### 3.2.1.3 CancelFailed
+
+#### 3.2.1.3.1 General description
+
+##### 3.2.1.3.1.1 Error description
+
+This Error is returned by Cancel if the cancelling of an Operation, as requested by the SCF, was not successful. Possible failure reasons are:
+
+- 1) unknownOperation – When the InvokeID of the operation to cancel is not known to SRF (this may also happen in case the operation has already been completed).
+- 2) tooLate – When the InvokeID is known but the execution of the operation is in a state that it cannot be cancelled anymore. For instance, the announcement is finished but the SpecializedResourceReport has not been sent to the SCF yet. The conditions for the occurrence of failure reason "tooLate" may be implementation dependent.
+- 3) operationNotCancellable, when the InvokeID points to an Operation that the SCF is not allowed to cancel.

+
+##### 3.2.1.6.1 General description
+
+###### 3.2.1.6.1.1 Error description
+
+The Service Logic Program could not be found in the SCF, because the required customer record does not exist, or the requested Service Logic Program Instance, indicated by the CorrelationID in "AssistRequestInstructions" does not exist anymore. These two cases should be distinguished as two different error situations, because the error procedure shows that the occurrence of the MissingCustomerRecord error is reported to the maintenance function, but the report to the maintenance function for the occurrence of the former case should be optional because it occurs not only in extraordinary situation but in ordinary situation. For example, the former may occur when the end user dials a missing free-phone number.

+
+After receiving this Error, the SSF-FSM returns to the state Idle. The CCF routes the call if necessary (default routing to a terminating announcement). If the call is already established (i.e. mid-call trigger or ApplyChargingReport), the CCF may maintain the call or disconnect it. The choice between these two options is network operator specific. In case of an assisting SSF, the temporary connection is released by the assisting SSF.

+
+### A) Receiving Operation
+
+|                |                 |                                                |
+|----------------|-----------------|------------------------------------------------|
+| Precondition:  | SDF-FSM state 1 | Idle (in case of Bind).                        |
+| or             | SDF-FSM state 3 | SCF Bound (in case of operations except Bind). |
+| Postcondition: | SDF-FSM state 2 | Bind Pending (in case of Bind).                |
+| or             | SDF-FSM state 3 | SCF Bound (in case of operations except Bind). |
+
+### B) Returning Error
+
+|                |                 |                                                |
+|----------------|-----------------|------------------------------------------------|
+| Precondition:  | SDF-FSM state 2 | Bind Pending (in case of Bind).                |
+| or             | SDF-FSM state 3 | SCF Bound (in case of operations except Bind). |
+| Postcondition: | SDF-FSM state 1 | Idle (in case of Bind).                        |
+| or             | SDF-FSM state 3 | SCF Bound (in case of operations except Bind). |
+
+The SDF could not perform the operation for security reasons and therefore sends a Security error to the SCF. After returning the error, no further error treatment is performed.

+
+B) SCF receives UnavailableResource Error from SRF
+
+Precondition: SCSM state 4.1 Waiting for Response from the SRF.
+
+Postcondition: SCSM state 4.1 Waiting for Response from the SRF.
+
+If the chosen resource cannot perform its function, the further treatment is service dependent.
+
+Examples: – request SSF to connect to alternative SRF;  
+– service processing without PlayAnnouncement or PromptAndCollectUserInfo (if possible);  
+– terminate service processing.
+
+### **Procedures at Responding Entity (SRF)**
+
+A) SRF receiving PlayAnnouncement or PromptAndCollectUserInfo
+
+Precondition: SRSM state 2 Connected; if initial PlayAnnouncement or PromptAndCollectUserInfo.
+
+or SRSM state 3 User Interaction; if not initial PlayAnnouncement or PromptAndCollectUserInfo.
+
+B) SRF is not able to perform its function (and cannot be replaced). SRF sends UnavailableResource.
+
+Precondition: SRSM state 3 User Interaction.
+
+Postcondition: SRSM state 3 User Interaction.
+
+### **3.2.1.16 UnexpectedComponentSequence**
+
+#### **3.2.1.16.1 General description**
+
+##### **3.2.1.16.1.1 Error description**
+
+The responding entity cannot start the processing of the requested operation because a SACF or MACF rule is violated, or the operation could not be processed in the current state of the FSM.

+
+In case of assisting SSF an error occurs in case an AssistRequestInstructions is sent while a relationship between SCF and assisting SSF has already been established, the SCF returns the error parameter. Service Logic and maintenance are informed. On receiving the error, the assisting SSF moves to Idle and the temporary connection is released.
+
+In case the operation is sent by an "initiating" SSF in the context of an existing relationship, the SCF returns the error parameter. Service Logic and maintenance are informed. On receiving the error, the SSF moves to Idle.

+
+In this case the SRF detects the erroneous situation, sends the UnexpectedComponentSequence error and remains in the same state. In the SCF, the Service Logic and maintenance functions are informed and the Service Logic decides about error treatment. Possible error treatment is to send the DisconnectForwardConnection operation to the SSF.
+
+### 3.2.1.16.5 Operations SRF → SCF
+
+- AssistRequestInstructions.
+
+In this case, an error occurs if the SRF has already an established relationship with the SCF and sends an AssistRequestInstructions. The SCF detects the erroneous situation, informs Service Logic and maintenance functions and returns the error parameter. On receiving the parameter, the SRF moves to Idle and releases the temporary connection.

+## 3.3 Detailed Operation procedures
+
+The intended use of operations and parameters from clause 2 not described in the following detailed procedure descriptions is for further study. For more information please refer to 6.4/Q.1214.
+
+### 3.3.1 ActivateServiceFiltering procedure
+
+#### 3.3.1.1 General description
+
+When receiving this operation, the SSF handles calls to destinations in a specified manner without request for instructions to the SCF. In the case of service filtering, the SSF executes a specific service filtering algorithm. For the transfer of service filtering results refer to the operation 'ServiceFilteringResponse'.
+
+##### 3.3.1.1.1 Parameters
+
+- filteredCallTreatment:
+
+This parameter specifies how filtered calls are treated. It includes information about the announcement to be played, the charging approach, the number of counters used and the release cause to be applied to filtered calls.
+
+i) sFBillingChargingCharacteristics:
+
+This parameter determines the charging to be applied for service filtering. Its content is network specific.
+
+NOTE – Actual format and encoding is for further study.
+
+ii) informationToSend:
+
+This parameter indicates an announcement, a tone or display information to be sent to the calling party. At the end of information sending, the call shall be released.
+
+• inbandInfo:
+
+This parameter specifies the inband information to be sent.
+
+– messageID:
+
+This parameter indicates the message(s) to be sent, it can be one of the following:
+
+1) elementaryMessageID:
+
+This parameter indicates a single announcement.
+
+2) text:
+
+This parameter indicates a text to be sent. The text shall be transformed to inband information (speech). This parameter consist of two subparameters, messageContent and attributes. The attributes of text may consist of items such as language.
+
+3) elementaryMessageIDs:
+
+This parameter specifies a sequence of announcements.
+
+4) variableMessage:
+
+This parameter specifies an announcement with one or more variable parts.
+
+– numberOfRepetitions:
+
+This parameter indicates the maximum number of times the message shall be sent to the end-user.
+
+– duration:
+
+This parameter indicates the maximum time duration in seconds that the message shall be played/repeated. ZERO indicates endless repetition.
+
+– interval:
+
+This parameter indicates the time interval in seconds between repetitions, i.e. the time between the end of the announcement and the start of the next repetition. This parameter can only be used when the number of repetitions is > 1.
+
+• tone:
+
+This parameter specifies a tone to be sent to the end-user.
+
+– toneID:
+
+This parameter indicates the tone to be sent.
+
+– duration:
+
+This parameter indicates the time duration in seconds of the tone to be sent. ZERO indicates infinite duration.
+
+• displayInformation:
+
+This parameter indicates a text string to be sent to the end-user. This information can not be received by a PSTN end-user.
+
+iii) maximumNumberOfCounters:
+
+This parameter provides the number of counters to be allocated as well as the number of destinations included in the service filtering, i.e. 'maximumNumberOfCounters' subsequent destination addresses beginning with the destination address provided in 'filteringCriteria' are used for service filtering. One counter is assigned to each of these destination addresses.
+
+The number of counters may only be >1 if the 'filteringCriteria' are of the type 'addressAndService'.
+
+iv) releaseCause:
+
+This parameter provides the cause value used for call release after the 'informationToSend' (for example announcement) has been sent to the calling party. If 'releaseCause' is not present, the default value is the same as the ISUP value decimal 31 (normal unspecified).
+
+b) filteringCharacteristics:
+
+This parameter indicates the severity of the filtering and the point in time when the 'ServiceFilteringResponse' shall be sent. It determines whether the 'interval' or the 'numberOfCalls' are used.
+
+i) interval:
+
+After expiration of the interval timer the next call to arrive causes following actions:
+
+- sending of an 'InitialDP' or a DP-specific operation;
+- sending of a 'ServiceFilteringResponse';
+- starting again the interval timer.
+
+When filtering is started the first interval is started.
+
+An interval of 0 indicates that all calls matching the filtering criteria will result in sending of an 'InitialDP' or a DP-specific operation and no filtering will be applied (i.e. no 'ServiceFilteringResponse' will be sent).
+
+An interval of -1 indicates that none of the calls matching the filtering criteria will either result in sending of an 'InitialDP' or a DP-specific operation or a 'ServiceFilteringResponse' operation.
+
+Other values indicate duration in seconds.
+
+ii) numberOfCalls:
+
+The *n* th call causes an 'InitialDP' or a DP-specific operation and a 'ServiceFilteringResponse' operation sent to the SCF. This threshold value is met if the sum of all counters assigned to one service filtering entity is equal to 'numberOfCalls'.
+
+A number of calls of 0 indicates that none of the calls matching the filtering criteria will result in sending of an 'InitialDP' or a DP-specific operation and a 'ServiceFilteringResponse' operation.
+
+c) filteringTimeout:
+
+This parameter indicates the duration of the filtering. When the time expires, a 'ServiceFilteringResponse' is sent to the SCF and service filtering is stopped. Two approaches are supported (duration or stopTime):
+
+i) duration:
+
+If the duration time expires, then service filtering is stopped and the final report is sent to the SCF.
+
+A duration of 0 indicates that service filtering is to be removed.
+
+A duration of -1 indicates an infinite duration.
+
+A duration of -2 indicates a network specific duration.
+
+Other values indicate duration in seconds.
+
+ii) stopTime:
+
+When the 'stopTime' is met then service filtering is stopped and the final report is sent to the SCF. If 'stopTime' was already met, i.e. the value of the stopTime is less than the value of the actual time but the difference does not exceed the value equivalent to 50 years, then service filtering is immediately stopped and the actual counter values are reported to the SCF. This occurs in cases where the SCF wishes to explicitly stop a running service filtering.
+
+d) filteringCriteria:
+
+This parameter specifies which calls are filtered based on 'serviceKey', 'callingAddressValue', 'calledAddressValue' or 'locationNumber'. It is a choice of 'servicekey' or 'addressAndService'.
+
+i) serviceKey:
+
+This parameter identifies unambiguously the requested IN service for which filtering should be applied.
+
+ii) addressAndService:
+
+This parameter identifies the IN service and dialled number for which filtering should be applied. The geographical area may also be identified ('callingAddressValue' and/or 'locationNumber').
+
+iii) calledAddressValue:
+
+This parameter contains the dialled number towards which filtering shall be applied. The complete called party number shall be specified.
+
+iv) serviceKey:
+
+This parameter identifies unambiguously the requested IN service for which filtering should be applied.
+
+v) callingAddressValue:
+
+This parameter contains the calling party number which identifies the calling party or geographical origin of the call for which filtering shall be applied.
+
+vi) locationNumber:
+
+This parameter identifies the geographical area from which the call to be filtered originates. It is used when 'callingAddressValue' does not contain any information about the geographical location of the calling party.
+
+e) startTime:
+
+This parameter defines when filtering is started. If 'startTime' is not provided or was already met, the SSF starts filtering immediately.
+
+### 3.3.1.2 Invoking Entity (SCF)
+
+#### 3.3.1.2.1 Normal procedure
+
+SCF Precondition:
+
+- SLPI detects that service filtering has to be initiated at the SSF.
+
+SCF Postconditions:
+
+- 1) SLPI starts an application timer to monitor the expected end of service filtering.
+- 2) The SCME is in the state "Waiting For ServiceFilteringResponse".
+
+Sending the 'ActivateServiceFiltering' operation causes a transition of the SCME from the state "Service Filtering Idle" to the state "Waiting For SSF Service Filtering Response". The SCME remains in this state until the application timer in the SLPI expires. The SCME is informed by the SLPI about timer expiration. Then it moves to the state "Service Filtering Idle".
+
+If no errors occurred after receiving an 'ActivateServiceFiltering' at the SSF an empty Return Result is sent to the SCF. That causes no state transition in the SCME.
+
+To change the parameters of an existing service filtering entity, the SCF has to send an 'ActivateServiceFiltering' operation with the same 'filtering Criteria'. The second parameter set replaces the first one.
+
+#### 3.3.1.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.1.3 Responding Entity (SSF)
+
+#### 3.3.1.3.1 Normal procedure
+
+SSF Precondition:
+
+- None.
+
+SSF Postcondition:
+
+- The SSME-FSM is in the state "Non Call Associated Treatment".
+
+If there is no already existing SSME-FSM for the "filteringCriteria" provided, then a new SSME-FSM is created. This SSME-FSM enters the state "Non-Call Associated Treatment" and initializes the service filtering for the specified IN calls. The parameters "filteredCallTreatment", "filteringCharacteristics", "filteringCriteria", "filteringTimeOut" and "startTime" are set as provided in the operation. A number of counters will be allocated and reset. In the case of the "startTime" that has not been met yet, the service filtering will be started at the specified point in time.
+
+If the operation "ActivateServiceFiltering" addresses an already existing service filtering entity, the parameters "filteredCallTreatment", "filteringCharacteristics", "filteringTimeOut" and "startTime" are modified as provided in the operation. In the case that the addressed service filtering entity is active, the SSF reports the counter values to the SCF via the operation "ServiceFilteringResponse". The service filtering process is stopped if an already expired "stopTime" or "duration" equal to ZERO or a new not yet met "startTime" is provided. The SSF then proceeds as described for "ServiceFilteringResponse". In the case of the "startTime" that has not been met yet, the service filtering will be continued at the specified point in time.
+
+If the service filtering proceeds, then the SSME-FSM remains in the state "Non-Call Associated Treatment". Otherwise the SSME-FSM moves to state "Idle Management".
+
+When a call matches several active "filteringCriteria" it should be subject to filtering on the most specific criteria, i.e. the criteria with the longest "callingAddressValue" or "locationNumber", or alternatively the criteria with the largest number of parameters specified.
+
+When performing service filtering with the "filteringCriteria"-"addressAndService", the first parameters checked will always be the "serviceKey" and "calledAddressValue".
+
+If an "ActivateServiceFiltering" operation is passed to the SSF with the "filteringCriteria" "addressAndService" with both "callingAddressValue" and "locationNumber" present, the following is applicable:
+
+- When the SSF receives a call that matches "serviceKey" and "calledAddressValue" (in the active "filteringCriteria"), it investigates whether or not the "locationNumber" is present in the initial address message. If it is present and matches the active "filteringCriteria", the call is filtered. If the SSF finds that the "locationNumber" is absent, then it will check the "callingAddressValue" and perform filtering depending on that parameter.
+
+If no errors occurred after receiving an "ActivateServiceFiltering" on the SSF, an empty Return Result is sent to the SCF. That causes no state transition in the SSME-FSM.
+
+Following application timers are used:
+
+- detect moment to start service filtering (start time);
+- duration time for service filtering;
+- interval time for service filtering (for timer controlled approach).
+
+#### 3.3.1.3.2 Error handling
+
+If the SSF detects an error with any of the defined error values, then this error is reported to the SCF.
+
+The event is recorded in the SSF and an error condition indicated.
+
+In case a new SSME-FSM should be created, the relationship is ended and all concerned resources (e.g. counters) are released. The SSME-FSM remains in the state "Idle Management".
+
+In case there is already an existing SSME-FSM, the service filtering data remains unchanged. The SSME-FSM remains in the state "Non-Call Associated Treatment".
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.2 ActivityTest procedure**
+
+#### **3.3.2.1 General description**
+
+This operation is used to check for the continued existence of a relationship between the SCF and SSF. If the relationship is still in existence, then the SSF will respond. If no reply is received within a given time period, then the SCF will assume that the SSF has failed in some way and will take the appropriate action.
+
+##### **3.3.2.1.1 Parameters**
+
+None.
+
+#### **3.3.2.2 Invoking Entity (SCF)**
+
+##### **3.3.2.2.1 Normal procedure**
+
+SCF Preconditions:
+
+- 1) A relationship exists between the SCF and the SSF.
+- 2) The activity test timer (Tati) expires, after which the 'ActivityTest' operation is sent to the SSF.
+
+SCF Postcondition:
+
+- If a Return Result 'ActivityTest' is received, the SCME resets the activity test timer and takes no further action.
+
+##### **3.3.2.2.2 Error handling**
+
+If a time-out on the 'ActivityTest' operation or a P-Abort is received from TCAP, this is an indication that the relationship with the SSF was somehow lost. If a time-out is received, SCF aborts the dialogue.
+
+The SLPI that was the user of this dialogue will be informed, the corresponding SCSM-FSM will move to the state "Idle".
+
+#### **3.3.2.3 Responding Entity (SSF)**
+
+##### **3.3.2.3.1 Normal procedure**
+
+SSF Precondition:
+
+- A relationship exists between the SCF and the SSF.
+
+SSF Postconditions:
+
+- 1) The SSME-FSM stays in, or moves to the state "Non Call Associated Treatment".
+- 2) If the Dialogue ID is active and if there is a SSF-FSM using the dialogue, the SSME sends a Return Result 'ActivityTest' to the SCF. If there are no other management activities, the SSME-FSM returns to the state "Idle Management"; or
+
+If the Dialogue ID is not active, the TCAP in the SSF will issue a P-Abort, the SSME will in that case never receive the 'ActivityTest' req.ind and thus will not be able to reply.
+
+##### **3.3.2.3.2 Error handling**
+
+Operation related error handling is not applicable, due to class 3 operation.
+
+### **3.3.3 AddEntry procedure**
+
+#### **3.3.3.1 General description**
+
+The X.500 'AddEntry' operation is used to request the SDF to add a leaf entry (either an object entry or an alias entry) in the DIT. For a full description of the AddEntry operation, see 11.1/X.511.
+
+##### **3.3.3.1.1 Parameters**
+
+See 11.1.1/X.511 and 11.1.2/X.511.
+
+### 3.3.3.2 Invoking Entity (SCF)
+
+#### 3.3.3.2.1 Normal procedure
+
+SCF Precondition:
+
+- SCSM: "SDF Bound" or "Wait for Subsequent Requests".
+
+SCF Postcondition:
+
+- SCSM: "SDF Bound".
+
+When the SCSM is in the state "Wait for Subsequent Requests" and a need of the service logic to add an entry in the SDF exists, an internal event [(e2) Request\_to\_SDF] occurs. Until the application process has not indicated with a delimiter (or a timer expiry) that the operation should be sent, the SCSM remains in the state "Wait for Subsequent Requests" and the operation is not sent. The operation is sent to the SDF in a message containing a Bind argument. The SCSM waits for the response from the SDF. The reception of the response [(E5) Response\_from\_SDF\_with\_Bind or (E4) Bind\_Error] to the Bind operation previously issued to the SDF causes a transition of the SCF to the state "SDF Bound" or to the state "Idle". When the SCSM has moved to state "Idle", the AddEntry operation was discarded. In the State "SDF Bound", the response of the AddEntry operation [(E7) Response\_from\_SDF] causes a transition of the SCF to the same state ("SDF Bound"). It may be either the result of the AddEntry operation or an error.
+
+When the SCSM is in the state "SDF Bound" and a need of the service logic to add an entry in the SDF exists, an internal event occurs. This event, called (e6) Request\_to\_SDF causes a transition to the same state "SDF Bound" and the SCSM waits for the response from the SDF. The reception of the response [(E7) Response\_from\_SDF] to the AddEntry operation previously issued to the SDF causes a transition of the SCF to the same state "SDF Bound". The response from the SDF may be either the result of the AddEntry operation or an error.
+
+#### 3.3.3.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 11.1.4/X.511 and 11.1.5/X.511 and the TCAP services that are used for reporting operating errors are described in 2.2.2.
+
+### 3.3.3.3 Responding Entity (SDF)
+
+#### 3.3.3.3.1 Normal procedure
+
+SDF Precondition:
+
+- SDSM: "SCF Bound" or "Bind Pending".
+
+SDF Postcondition:
+
+- SDSM "SCF Bound".
+
+When the SDF is in the state "Bind Pending", the external event (E3) Request\_from\_SCF caused by the reception of an 'AddEntry' operation from the SCF occurs. The SDF does not proceed to the operation until a Bind operation has been successfully executed. It remains in the same state.
+
+When the SDF is in the state "SCF Bound", the external event (E7) Request\_from\_SCF caused by the reception of an 'AddEntry' operation from the SCF occurs. The SDF waits for the response to the operation.
+
+On the receipt of the event (E7) and before adding the new entry item, the SDF takes the following actions:
+
+- verify that the superior object to which the entry should be added exists in the SDF;
+- verify that the entry does not already exist in the SDF;
+- verify that the access rights to add the entry and each of its components (attributes and values) are sufficient;
+- verify that the entry conforms to the Directory schema.
+
+After the specified actions indicated above are successfully executed, the entry is added into the SDF database. A null result is returned to the SCF. The sending of the result corresponds to the event (e6) Response\_to\_SCF.

+
+Generic error handling for the operation related errors is described in 11.1.4/X.511 and 11.1.5/X.511 and the TCAP services that are used for reporting operating errors are described in 2.2.2.
+
+## **3.3.4 AnalysedInformation Procedure**
+
+### **3.3.4.1 General description**
+
+This operation is sent by the SSF to the SCF after detecting a valid trigger condition at the Analysed Info DP, or to report an event requested by RequestReportBCSMEvent.

+
+- 2) The OriginalCalledNumber parameter in the IAM if the SSF-CCF does not already have a value for the OriginalCalledNumber AND if the SSF-CCF routes the call to an SS No. 7 trunk (for ISDN-UP signalling).
+
+Other AnalyseInformation Requirements.
+
+- If the SSF-CCF has associated a Business Group ID with the call and the call is routed over an SS No. 7 trunk, the SSF-CCF shall include this information in the Business Group parameter of the network specific ISDN-UP IAM (network operator specific).

+
+#### 3.3.7.1 General description
+
+This operation is used by the SSF to report charging related information to the SCF as requested by the SCF using the 'ApplyCharging' operation.
+
+During a connection configuration the 'ApplyChargingReport' operation may be invoked on multiple occasions. For each call party and each connection configuration, the 'ApplyChargingReport' operation may be used several times. Note that at least one 'ApplyChargingReport' operation is to be sent at the end of the connection configuration charging process.

+
+##### 3.3.7.1.1 Parameters
+
+- CallResult:
+
+This parameter provides the SCF with the charging related information previously requested using the 'ApplyCharging' operation. The 'CallResult' will include the 'partyToCharge' parameter as received in the related 'ApplyCharging' operation to correlate the result to the request.

+
+##### **3.3.8.1.1 Parameters**
+
+- correlationID:
+
+This parameter is used by the SCF to associate the 'AssistRequestInstructions' from the assisting SSF or by a SRF with the request from the initiating SSF. The value of the 'correlationID' may be extracted from the digits received from the initiating SSF or be all of the digits.
+
+- iPAvailable:

+On receipt of this operation in the SCSM state "Waiting for Assist Request Instructions", the SCP has to perform the following actions.
+
+If the 'AssistRequestInstructions' operation was received from an assisting SSF, and the resource is available, the SCSM prepares the 'ConnectToResource' and 'PlayAnnouncement' or 'PromptAndCollectUserInfo' to be sent to the assisting SSF.
+
+The SCF determines SSF-SRF by means of 'correlationID', 'destinationNumber' or network knowledge.
+
+If the 'AssistRequestInstructions' operation was received from a SRF, and the resource is available, the SCSM prepares the 'PlayAnnouncement' or 'PromptAndCollectUserInfo' to be sent to the SRF.
+
+On receipt of this operation from the Handoff SSF, the SCSM associated with the Handoff SSF transits from the "Idle" state to the "Preparing SSF Instructions" state.

+
+### **3.3.9 Bind procedure**
+
+#### **3.3.9.1 General description**
+
+The X.500 'Bind' operation is used by the SDF to create an authenticated association between an SCF and an SDF on behalf of the end user. It carries the authentication information of the end user if any. For a full description of the Bind operation, see 8.1/X.511.
+
+##### **3.3.9.1.1 Parameters**
+
+See 8.1.2/X.511 and 8.1.3/X.511.
+
+### **3.3.9.2 Invoking Entity (SCF)**
+
+#### **3.3.9.2.1 Normal procedure**
+
+SCF Preconditions:
+
+- SCSM: "Idle".
+
+SCF Postconditions:
+
+- 1) SCSM: "SDF Bound" in case of success.
+- 2) SCSM: "Idle" in case of failure.
+
+When the SCSM is in the state "Idle" and a need of the service logic to interrogate an SDF exists, an internal event occurs. This event, called (e1) Bind\_Request, causes a transition to the state "Wait for Subsequent Request" and other operations are awaited. Until the application process has not indicated by a delimiter that the Bind should be sent, the SCSM remains in the state "Wait for Subsequent Requests" and the operation is not sent. The reception of the delimiter causes a transition to the state "Wait for Bind result" through the internal transition (e3) Request\_to\_SDF\_with\_Bind. The operation is sent to the SDF. The SCSM waits for the response from the SDF. The reception of the response [(E5) Response\_from\_SDF\_with\_Bind] to the Bind operation previously issued to the SDF causes a transition of the SCF to the state "SDF Bound" if the result of the Bind operation is positive. Otherwise the reception of an error [(E4) Bind\_Error] moves back the SCSM to the state "Idle".
+
+#### **3.3.9.2.2 Error handling**
+
+Generic error handling for the operation related errors is described in 8.1.4/ X.511 and the TCAP services that are used for reporting operating errors are described in 2.2.2.
+
+### **3.3.9.3 Responding Entity (SDF)**
+
+#### **3.3.9.3.1 Normal procedure**
+
+SDF Preconditions:
+
+- SDSM: "Idle".
+
+SDF Postconditions:
+
+- 1) SDSM: "SCF Bound" (success).
+- 2) SDSM: "Idle" (failure).
+
+The SDF is initially in the state "Idle". After accepting the external event (E1) Bind\_from\_SCF caused by the reception of a 'Bind' operation from the SCF, a transition to state "Bind Pending" occurs. The SDF performs the Bind operation according to the contents of the Bind argument. Once the SDF has completed the 'Bind' operation, the result or error indication is returned to the SCF. The SDF returns to the state "Idle" if the Bind fails or to the state "SCF Bound" if the Bind is successful. Should the Bind request succeed, the result returned may consist of credentials of the DirectoryBindResult. These credentials allow the user to establish the identity of the Directory. They allow information identifying the DSA (that is directly providing the Directory service) to be conveyed to the DUA. The credentials are of the same form (i.e. name, password) as those supplied by the user.

+### **3.3.10 CallGap procedure**
+
+#### **3.3.10.1 General description**
+
+This operation is used to request the SSF to reduce the rate at which specific service requests are sent to the SCF.
+
+### 3.3.10.1.1 Parameters
+
+a) gapCriteria:
+
+This parameter identifies the criteria for a call to be subject to call gapping.
+
+i) calledAddressValue:
+
+This parameter indicates that call gapping will be applied when the leading digits of the dialled number of a call attempt match those specified in "gapCriteria".

+
+Other values indicate duration in seconds.
+
+ii) gapInterval:
+
+This parameter specifies the minimum time between calls being allowed through.
+
+An interval of 0 indicates that calls meeting the gap criteria are not to be rejected.

+### 3.3.10.2 Invoking Entity (SCF)
+
+#### 3.3.10.2.1 Normal procedure
+
+SCF Preconditions:
+
+- The SCF detects an overload, condition persists and call gapping has to be initiated at the SSF; or
+- the SCF receives a manually initiated call gapping request.
+
+SCF Postcondition:
+
+- The SCME-FSM remains in the same state upon issuing the "CallGap" operation.
+
+A congestion detection and control algorithm monitors the load of SCP resources. After detection of a congestion situation the parameters for the "CallGap" operation are provided.
+
+If the congestion level changes, new 'CallGap' operations may be sent for active gap criteria but with new gap interval. If no congestion is detected, gapping may be removed.
+
+A manual initiated call gap will take prevail over an automatic initiated call gap.
+
+#### 3.3.10.2.2 Error handling
+
+Operation related error handling is not applicable, due to class 4 operation.
+
+### 3.3.10.3 Responding Entity (SSF)
+
+#### 3.3.10.3.1 Normal procedure
+
+SSF Preconditions:
+
+- call gapping for gapCriteria is not active; or  
+call gapping for gapCriteria is active.
+
+SSF Postconditions:
+
+- 1) the SSME-FSM is in the state "Non call associated treatment";
+- 2) call gapping for gapCriteria is activated; or  
+call gapping for gapCriteria is renewed; or  
+call gapping for gapCriteria is removed.
+
+If there is no already existing SSME-FSM for the gap criteria provided, a new SSME-FSM is created. This SSME-FSM enters the state 'Non-call associated treatment' and initializes call gapping for the specified IN calls. The parameters 'gapIndicators', 'controlType' and 'gapTreatment' for the indicated gap criteria will be set as provided by the 'CallGap' operation.
+
+In general, the manuallyInitiated call gapping will prevail over automatically initiated ('sCPOverloaded'). More specifically, the following rules will be applied in the SSF to manage the priority of different control Types associated with the same 'gapCriteria':
+
+- If an SSME-FSM already exists for the 'gapCriteria' provided, then:
+  - 1) If the (new) 'controlType' equals an existing 'controlType', then the new parameters (i.e. 'gapIndicators' and 'gapTreatment') will overwrite the existing parameter values.
+  - 2) If the (new) 'controlType' is different than the existing 'controlType', then the new parameters (i.e. 'controlType', 'gapIndicators', and 'gapTreatment') will be appended to the appropriate SSME-FSM (in addition to the existing parameters). The SSME-FSM remains in the state "Non-Call Associated Treatment".
+
+If the SSF meets a TDP, it will check if call gapping was initiated either for the 'serviceKey' or for the 'calledAddressValue' assigned to this TDP. If not, an 'InitialDP' or a DP-specific operation can be sent. In case call gapping was initiated for 'calledAddressAndService' or 'callingAddressAndService' and the 'serviceKey' matches, a
+
+check on the 'calledAddressValue' and 'callingAddressValue' – and optionally 'locationNumber' – for active call gapping is performed. If not, an 'InitialDP' or a DP-specific operation can be sent.
+
+In case of gapping on 'callingAddressAndService' and the parameter 'locationNumber' is present, gapping will be performed on 'locationNumber' instead of 'callingAddressValue'.
+
+If a call to a controlled number matches only one 'gapCriteria', then the corresponding control is applied. If both 'manuallyInitiated' and 'sCPOverload' controls are active, then only the manually initiated control will be applied.
+
+If a call to a controlled called number matches several active 'gapCriteria', then only the 'gapCriteria' associated with the longest called party number should be used, and the corresponding control should be applied. For example, the codes 1234 and 12345 are under control. Then the call with 123456 is subject to the control on 12345. Furthermore, if both 'manuallyInitiated' and 'sCPOverloaded' 'controlTypes' are active for this 'gapCriteria', then the 'manuallyInitiated' control will be applied.
+
+If call gapping shall be applied and there is no gap interval active, an "InitialDP" or a DP-specific operation can be sent including the "cGEncountered" parameter according to the specified controlType. A new gap interval will be initiated as indicated by "gapInterval".
+
+If a gap interval is active, no "InitialDP" or a DP-specific operation is sent and the call is treated as indicated by "gapTreatment".
+
+The call gap process is stopped if the indicated duration equals ZERO.
+
+If call gapping proceeds then the SSME-FSM remains in the state "Non-call associated treatment". Otherwise, the SSME-FSM moves to state "idle management".

+- 1) At least one party disconnects from a call or call set-up is not completed.
+- 2) Requested call information has been collected.
+- 3) 'CallInformationReport' is pending due to a previously received 'CallInformationRequest' operation.
+- 4) A control relationship exists between the SCF and the SSF.
+
+SSF Postcondition:
+
+- The SSF-FSM shall move to the "Idle" state in the case where no other report requests are pending and no EDPs are armed, otherwise the SSF-FSM shall remain in the same state.

+- B party release;
+- B party busy;
+- SSF no answer timer expiration;
+- route select failure indicated by the network;
+- release call initiated by the SCF;

+
+If a 'CallInformationReport' has been sent to the SCF then no 'CallInformationReport' is pending, i.e. a further 'CallInformationReport', for example in the case of follow-on, has to be explicitly requested by the SCF.
+
+If an event causing the 'CallInformationReport' is also detected by an armed EDP-R, then immediately after 'CallInformationReport', the corresponding 'EventReportBCSM' has to be sent.

+### **3.3.11.2.2 Error handling**
+
+Operation related error handling is not applicable, due to class 4 operation.
+
+### **3.3.11.3 Responding Entity (SCF)**
+
+#### **3.3.11.3.1 Normal procedure**
+
+SCF Preconditions:
+
+- 1) An SLPI is expecting 'CallInformationReport'.
+- 2) A control relationship exists between the SCF and the SSF.

+
+If 'CallInformationReport' is outstanding and the service logic program indicates that the processing has been completed, the SCSM remains in the same state until it receives the 'CallInformationReport' operation.
+
+When the SCF receives the 'CallInformationReport' operation and the service logic processing has been completed, then the SCSM moves to the "Idle" state.
+
+When the SCF receives the 'CallInformationReport' operation and the service logic processing has not been completed yet, then the SCSM remains in the same state (EventReportBCSM or ApplyChargingReport pending).
+
+#### **3.3.11.3.2 Error handling**
+
+If requested information is not available, a 'CallInformationReport' will be sent, indicating the requested information type, but with 'RequestedInformationValue' filled in with an appropriate default value as specified by the network operator.

+
+### 3.3.12 CallInformationRequest procedure
+
+#### 3.3.12.1 General description
+
+This operation is used to request the SSF to record specific information about a single call and report it to the SCF using the 'CallInformationReport' operation.
+
+##### 3.3.12.1.1 Parameters
+
+- requestedInformationTypeList:
+
+This parameter specifies a list of specific items of information which is requested.
+
+The list may contain:
+
+- callAttemptElapsedTime:  
+This parameter indicates the duration between the end of INAP processing of operations initiating call set-up ('Connect', 'AnalyseInformation', 'CollectInformation', 'Continue' and 'SelectRoute') and the received answer indication from the called party side.  
+In case of unsuccessful call set-up the network event indicating the unsuccessful call set-up stops the measurement of 'callAttemptElapsedTime'.
+- callStopTime:  
+This parameter indicates the time stamp when the connection is released.
+- callConnectedElapsedTime:  
+This parameter indicates the duration between the received answer indication from the called party side and the release of the connection.
+- calledAddress  
+This parameter indicates the incoming called party address that was received by the SSF (i.e. before translation by the SCF) and is as available on the UNI or NNI and interpreted as per the numbering plan.
+- releaseCause:  
+See Recommendation Q.762.
+
+Any set of these values can be requested.
+
+#### 3.3.12.2 Invoking Entity (SCF)
+
+##### 3.3.12.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) The SLPI has determined that a 'CallInformationRequest' operation has to be sent by the SCF.
+
+SCF Postcondition:
+
+- The SLPI is expecting a 'CallInformationReport' from SSF.
+
+When the service logic program requests call information, the SCF sends the 'CallInformationRequest' operation to the SSF to request the SSF to provide call related information.
+
+The 'CallInformationRequest' operation specifies the information items to be provided by the SSF.
+
+##### 3.3.12.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.12.3 Responding Entity (SSF)
+
+#### 3.3.12.3.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) Call origination attempt has been initiated.
+- 2) A control relationship exists between SSF and SCF.
+
+SSF Postconditions:
+
+- 1) Requested call information is retained by the SSF.
+- 2) The SSF is waiting for further instructions.
+
+The SSF may receive the "CallInformationRequest" operation within an existing Call Associated (CA) dialogue only.
+
+The "CallInformationRequest" operation is accepted by the SSF Finite State Machine (SSF-FSM) only in the state "Waiting for Instructions". The operation does not lead to any transition to another state.
+
+The SSF allocates a record and stores the requested information if already available and prepares the recording of information items, that will become available later like for example "callStopTimeValue".
+
+#### 3.3.12.3.2 Error handling
+
+In any other than the "Waiting for Instruction" state the "CallInformationRequest" operation will be handled as an error with the error code "UnexpectedComponentSequence".
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.13 Cancel procedure
+
+#### 3.3.13.1 General description
+
+The SCF uses this class 2 operation to request the SRF-SSF to cancel a correlated previous operation.
+
+The SRF operation to be deleted can be either a 'PlayAnnouncement' operation or a 'PromptAndCollectUserInfoInformation' operation.
+
+The cancellation of an operation is indicated via a respective error indication, "Cancelled", to the invoking entity of the cancelled "PlayAnnouncement" or "PromptAndCollectUserInfoInformation" operation. The 'Cancel' operation can also be used to cancel all outstanding requests and enable the state machine (SSF) to go to idle. In this case the 'Cancel' operation does not specify any specific operation to be cancelled.
+
+##### 3.3.13.1.1 Parameters
+
+- invokeID:  
+This parameter specifies which operation is to be cancelled, i.e. PromptAndCollectUserInfoInformation or PlayAnnouncement.
+- allRequests:  
+This parameter indicates that all active requests for EDP reports (generic or DP specific), "ApplyChargingReport" and "CallInformationReport" should be cancelled.
+
+NOTE – This cancellation is different from the invokeID based cancel mechanism described above.
+
+#### 3.3.13.2 Invoking Entity (SCF)
+
+##### 3.3.13.2.1 Normal procedure
+
+The SCF may either invoke this operation to the SSF or to the SRF, different conditions will prevail in each case.
+
+SCF Preconditions:
+
+- 1) a control relationship exists between the SCF and the SSF-SRF;
+- 2) an SLPI in the "Waiting for response from SRF" state has determined that a previously requested operation is to be cancelled; or  
+an SLPI has determined that it is no longer interested in any reports or notifications from the SSF and that the control relationship should be ended.
+
+SCF Postcondition:
+
+- the SLPI remains in the "Waiting for Response from SRF" state; or  
+in case all requests are cancelled, the control relationship with the concerned FE (SSF) is ended and the SCSM-FSM returns to "Idle" state.
+
+### **3.3.13.2.2 Error handling**
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.13.3 Responding Entity (SRF)**
+
+#### **3.3.13.3.1 Normal procedure**
+
+SRF Precondition:
+
+- A PlayAnnouncement or PromptAndCollectUserInfo operation has been received and the SRF is in the "User Interaction" state.
+
+SRF Postcondition:
+
+- The execution of the PlayAnnouncement or PromptAndCollectUserInfo operation has been aborted and the SRF remains in the "User Interaction" state.
+
+#### **3.3.13.3.2 Error handling**
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.13.4 Responding Entity (SSF)**
+
+#### **3.3.13.4.1 Normal procedure**
+
+SSF Precondition:
+
+- The SSF-FSM is in the state "Waiting for Instructions" or "Monitoring".
+
+SSF Postcondition:
+
+- 1) all active requests for reports and notifications have been cancelled;
+- 2) in case the SSF-FSM was in state "Monitoring" it shall return to idle; or  
+in case the SSF-FSM was in state "Waiting for Instructions" it will remain in that state.
+
+A subsequent call-processing operation will move the SSF-FSM state to "Idle". The call, if in active state, is further treated by SSF autonomously as a normal (non-IN-) call.
+
+#### **3.3.13.4.2 Error handling**
+
+Sending of return error on cancel is not applicable in the cancel "allRequests" case. Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.14 CollectedInformation procedure**
+
+#### **3.3.14.1 General description**
+
+This operation is sent by the SSF after detection of a TDP-R<sub>x</sub>, TDP-N, EDP-R, or EDP-N in the originating BCSM, to indicate availability of complete initial package/dialling string from the originating party.
+
+### 3.3.14.1.1 Parameters

+
+### 3.3.14.2 Invoking Entity (SSF)
+
+#### 3.3.14.2.1 Normal procedure
+
+SSF Preconditions for TDP-R and TDP-N:
+
+- 1) An event resulting in trigger criteria being met has occurred at the Collected\_Information DP (e.g. Off\_Hook\_Delay, Channel\_Setup\_PRI, Shared\_Interoffice\_Trunk).
+- 2) Call gapping and SS No. 7 overload are not in effect for the call, and the call is not to be filtered.
+
+SSF Preconditions for EDP-R and EDP-N:
+
+- 1) A control relationship has been established and the SCF requests Collected\_Information as EDP-R or EDP-N.
+- 2) Call processing reaches the Collected\_Information DP.
+
+SSF Postcondition for TDP-R:
+
+- A control relationship has been established and the SSF waits for instructions from the SCF.
+
+SSF post-condition for EDP-R:
+
+- The control relationship continues and the SSF waits for instructions from the SCF.
+
+SSF post-condition for TDP-N and EDP-N:
+
+- Call processing continues at the Analysed\_Information PIC.
+
+The SSF/CCF collects enough information (e.g. a feature code, prefix, address information, etc.) from the originating access to process the call. This information is collected according to the dialling plan assigned to the originating access:
+
+- 1) For a call from a non-ISDN line, the SSF-CCF sends an in-band prompt (e.g. dial tone) to prompt the user, attaches a digit receiver, collects digits and applies inter-digit timing. From a non-ISDN line, the "dialling plan in force" is the dialling plan assigned to the line. For example, if a Private Dialling Plan (PDP) (sometimes referred to as a Customized Dialling Plan) is assigned, then that PDP is considered to be the "dialling plan in force". If, on a given call, the caller dials an access code to escape to a Public Office Dialling Plan (PODP) (i.e. Recommendation E.164), then that PODP is considered to be the "dialling plan in force". In this case, call processing can not return to the PDP at this SSF-CCF. If a PDP is not assigned, then a PODP is assumed to be the "dialling plan in force".
+- 2) For a call from an ISDN user following *en bloc* sending procedures (i.e. all the information necessary to process the call, which can include a feature code, feature activator, called party number, etc., is included in the SETUP message), no further action is taken on the originating access interface. For a call from an ISDN user not following *en bloc* sending procedures, the SSF-CCF prompts the user with a SETUP ACKnowledge message to send more information. Overlap sending procedures are then followed.
+
+For a call from an ISDN BRI or PRI, the "dialling plan in force" is determined by the type of number and numbering plan field of the called party number information element. If this field indicates "unknown" or if the keypad information element is used, then the dialling plan is determined as defined for non-ISDN lines above.
+
+- 3) For conventional trunks, if required by the trunk type, an appropriate start signal is returned. A digit receiver is attached, digits are collected and inter-digit timing is applied.
+
+For a call from a conventional trunk, the number received in signalling is expected to be a non-private number that conforms to Recommendation E.164.
+
+- 4) For SS No. 7 trunks, all the information may be available in the IAM or may come in subsequent messages (i.e. overlap sending). A check is made to ensure that the IAM contains all the information necessary to process the call.
+
+For a call from an SS No. 7 trunk, the number received in signalling is expected to be a non-private number that conforms to Recommendation E.164.
+
+- 5) For private-facility trunks, if required by the private-facility trunk group, an appropriate start signal is returned. Depending on the private-facility trunk group, digits may be collected.
+
+Following the trigger detection (due to the DP criteria assigned being met) related to an armed TDP-R or TDP-N in the BCSM at the Collected\_Information DP, caused by a call origination attempt, the SSF checks if call gapping, SS No. 7 overload, or service filtering are not in effect for the related call segment. If these conditions are met, then the CollectedInformation operation is invoked by the SSF. The address of the SCF to which the CollectedInformation has to be sent is determined on the basis of trigger instance related data. The SSF provides parameters as per rules defined in 6.4.4/Q.1214. For TDP-R, a control relationship is established to the SCF and the SSF application timer  $T_{\text{SSF}}$  is set when the SSF sends the CollectedInformation operation for requesting instructions from the SCF.  $T_{\text{SSF}}$  is used to prevent excessive call suspension time. For EDP-R,  $T_{\text{SSF}}$  is also used. For TDP-N and EDP-N, no new control relationship is established. Hence,  $T_{\text{SSF}}$  is not set.
+
+### 3.3.14.2.2 Error handling
+
+If the destination SCF is not accessible, then the call is given final treatment (other treatments are for further study). On expiration of  $T_{\text{SSF}}$  before receiving any operation, the SSF aborts the interaction with the SCF and the call is given final treatment (e.g. routing to a final announcement). If the calling party abandons after the sending of the CollectedInformation operation, then the SSF aborts the control relationship after the first answer message from the SCF has been received. If the caller abandons the call and  $T_{\text{SSF}}$  is running, then the Transaction ID is held open until  $T_{\text{SSF}}$  is satisfied or expires. If the caller abandons the call and Timer  $T_{\text{SSF}}$  is not running, then procedures to support the encountered situation (e.g. procedures to report the condition of Caller Abandon, procedures associated with the condition of  $T_{\text{SSF}}$  Timer Expired), shall be followed.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.14.3 Responding Entity (SCF)
+
+#### 3.3.14.3.1 Normal procedure
+
+SCF Preconditions (TDP):
+
+- None.
+
+SCF Preconditions (EDP):
+
+- 1) For an EDP-R at the SSF, an existing control relationship is in place and an SLPI is running.
+- 2) For an EDP-N, an existing monitoring relationship is in place and an SLPI is running.
+
+SCF Postconditions (TDP):
+
+- 1) An SLPI has been invoked.
+- 2) For a TDP-R, a control relationship is established, and an SLPI has been invoked.
+- 3) For a TDP-R, an SSF instruction is being prepared.
+- 4) For a TDP-N, no relationship is established. An SLPI has been invoked, executes and terminates.
+
+SCF Postconditions (EDP):
+
+- For an EDP, the SCSM-FSM stays in the substate "Waiting for Notification or Request" if the message type was notification and there are still EDPs armed or a "CallInformationReport" or "ApplyChargingReport" requested; or
+
+the SCSM-FSM moves to the state "Idle" if the message type was notification and there are no more EDPs armed, no "CallInformationReport" or "ApplyChargingReport" are requested; or
+
+the SCSM-FSM moves to the state "Preparing SSF Instructions" if the message type was request.
+
+For TDP-R, on receipt of the CollectedInformation operation, the SCSM moves from "Idle" state to the state "Preparing SSF Instructions". A control relationship to the related SSF is created. A Service Logic Program Instance (SLPI) is invoked for process the CollectedInformation operation based on the triggerType parameter. By means of this control relationship, the SCF may influence the Basic Call Processing in accordance with the service logic invoked. The actions to be performed in the SLPI depend on the parameters conveyed via this operation and the SLPI (i.e. the requested IN service itself).
+
+For EDP-R, on receipt of the CollectedInformation operation, the SCSM moves from "Waiting for Notification" state to the state "Preparing SSF Instructions". A control relationship to the related SSF continues. A Service Logic Program Instance (SLPI) is invoked for process the CollectedInformation operation based on the triggerType parameter. By means of this control relationship, the SCF may influence the Basic Call Processing in accordance with the service logic invoked. The actions to be performed in the SLPI depend on the parameters conveyed via this operation and the SLPI (i.e. the requested IN service itself).
+
+For TDP-N, the SCSM remains in state "Idle" and takes appropriate action on the notification.
+
+For EDP-N, if this is the last event notification and there are no CallInformationReport and ApplyChargingReport pending, the SCSM returns to state "Idle". Otherwise, it remains in state "Waiting for Notification or Report". Appropriate actions on the notification are taken.
+
+### **3.3.14.3.2 Error handling**
+
+If the CollectedInformation operation is rejected, then the SCSM remains in the same state. The maintenance function is informed and no SLPI is invoked. Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.15 CollectInformation procedure**
+
+#### **3.3.15.1 General description**
+
+The CollectInformation is a class 2 operation which is used by the SCF to request the call to return to the Collect\_Information PIC, and then perform the basic originating call processing actions associated with this PIC (e.g. the checking of information in the CalledPartyNumber parameter with the supported dialling plan). This operation uses only the resources of the SSF-CCF to collect the information. The use of this operation is only appropriate for a call which had not yet left the set-up phase.
+
+When the user provides calledPartyNumber, Collect\_Information PIC processing includes collecting of destination information from a calling party. When the calledPartyNumber is included (as dialledDigits) in the Collect\_Information operation, further collection is not performed (e.g. SSF-CCF checks the provided calledPartyNumber against the supported dialling plan).
+
+#### **3.3.15.1.1 Parameters**
+
+- alertingPattern:  
+See Recommendation Q.1290. It only applies if the network signalling support this parameter or if SSF is the terminating local exchange for the subscriber.
+- numberingPlan:  
+See Recommendation Q.763 Numbering Plan for encoding.
+- originalCalledPartyID:  
+See Recommendation Q.762 Original Called Number signalling information.
+- travellingClassMark:  
+See Recommendation Q.1290. This parameter contains the travelling class mark information of the calling party. It uses the LocationNumber format which is based on the Q.763 Location Number format.
+- callingPartyNumber:  
+See Recommendation Q.762.
+- dialledDigits:  
+This parameter is applied against the supported dialling plan in the SSF-CCF and, if valid, is used in routing of the call. If provided, it replaces the calledPartyNumber for the call.
+
+#### **3.3.15.2 Invoking Entity (SCF)**
+
+##### **3.3.15.2.1 Normal procedure**
+
+SCF Precondition:
+
+- An SLPI has determined that more information from the calling party is required to enable processing to proceed.
+
+SCF Postcondition:
+
+- SLPI execution is suspended pending receipt of dialled digits.
+
+This operation is invoked in the SCSM-FSM state "Preparing SSF Instructions" if the SLP requires additional information to progress the call. It causes a transition of the FSM to the state "Waiting for Notification or Report".
+
+### **3.3.15.2.2 Error handling**
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.15.3 Responding Entity (SSF)**
+
+#### **3.3.15.3.1 Normal procedure**
+
+SSF Precondition:
+
+- A TDP Request has been invoked.
+
+SSF Postconditions:
+
+- 1) The SSF has executed a transition to the state "Monitoring".
+- 2) The SSF performs the call processing actions to collect destination information from the calling party. This may include prompting the party with in-band or out-band signals.
+- 3) Basic call processing is resumed at PIC 2.
+
+The operation is only valid in the state "Waiting for Instruction" and after having received an operation 'RequestReportBCSMEEvent' for DP2. The SSP has to perform the following actions:
+
+- The SSF cancels  $T_{\text{SSF}}$ .
+- When DP2 will be encountered, an 'EventReportBCSM' operation will be invoked, and the SSF-FSM will return to the state "Waiting for Instructions".
+
+#### **3.3.15.3.2 Error handling**
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4 .
+
+### **3.3.16 Connect procedure**
+
+#### **3.3.16.1 General description**
+
+This operation is used to request the SSF to perform the call processing actions to route a call to a specific destination. To do so, the SSF may use destination information from the calling party (e.g. dialled digits) and existing call set-up information (e.g. route index to a list of trunk groups) depending on the information provided by the SCF.
+
+In general, all parameters which are provided in a Connect operation to the SSF shall replace the corresponding signalling parameter in the CCF, if the relevant parameter has already been received in the CCF, and shall be used for subsequent call processing. Parameters which are not provided by the Connect operation shall retain their value (if already assigned) in the CCF for subsequent call processing.
+
+##### **3.3.16.1.1 Parameters**
+
+- destinationRoutingAddress:
+
+This parameter contains the list of called party numbers (see Recommendation Q.762) towards which the call is to be routed. The encoding of the parameter is defined in Recommendation Q.763. The 'destinationRoutingAddress' may include the 'correlationID' and 'scfID' if used in the context of a hand-off procedure, but only if 'correlationID' and 'scfID' are not specified separately.
+
+- alertingPattern:
+
+See Recommendation Q.1290. It only applies if the network signalling support this parameter or if SSF is the terminating local exchange for the subscriber.
+
+- correlationID:
+
+This parameter is used by the SCF to associate the 'AssistRequestInstructions' operation from the assisting SSF with the Request from the initiating SSF. The 'correlationID' is used in the context of a hand-off procedure and only if the correlation id is not embedded in the 'destinationRoutingAddress'. The network operators has to decide about the actual mapping of this parameter on the used signalling system.
+
+- cutAndPaste:  
+This parameter is used by the SCF to instruct the SSF to delete (cut) a specified number of leading digits that it has received from the calling party and to paste the remaining dialled digits on to the end of the digits supplied by the SCF in the 'destinationRoutingAddress'.
+- forwardingCondition:  
+Indicates the condition that must be met to complete the Connect operation.
+- iSDNAccessRelatedInformation:  
+Carries the same information as the protocol element ISUP Access Transport parameter in Recommendation Q.762.
+- originalCalledPartyID:  
+See Q.762 Original Called Number signalling information. The use of this parameter in the context of the 'Connect' operation is to be specified by the network operator.
+- routeList:  
+This parameter is used to select the outgoing trunk group used for routing the call. A sequence of routes is provided to allow flexible routing for applications such as VPN without increasing the number of queries required for such applications.
+- scfID:  
+See Recommendation Q.1290. The scfID is used in the context of a hand-off procedure and only if the SCF id is not embedded in the 'destinationRoutingAddress'. The network operator has to decide about the actual mapping of this parameter on the used signalling system.
+- travellingClassMark:  
+The SCF uses the travellingClassMark parameter to provide essential route selection information to the SSF. The SSF uses this information to populate the outgoing ISUP-IAM message, the population and mapping of this parameter is network operator specific.
+- carrier:  
+See Recommendation Q.1290. In this message, the carrier selection field is null (00000000) and Carrier ID indicates the carrier to use for the call.
+- serviceInteractionIndicators:  
+This parameter contains indicators sent from the SCF to the SSF for control of the network based services at the originating exchange and the destination exchange.
+- callingPartyNumber:  
+This parameter, if present, is used to identify the calling party for the call (see Q.762 Calling Party Number). It may be used for applications such as UPT, where only the SCF can verify the identity of the calling party.
+- callingPartysCategory:  
+See Recommendation Q.762 Calling Party Category signalling information.

+### 3.3.16.2 Invoking Entity (SCF)
+
+#### 3.3.16.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) An SLPI has determined that a 'Connect' has to be sent by the SCF.
+
+SCF Postcondition:
+
+- SLPI execution may continue.
+
+In the SCSM-FSM state "Preparing SSF Instructions", this operation is invoked by the SCF if the service logic results in the request to the SSF to route a call to a specific destination. If no event monitoring has been requested and no reports (CallInformationReport and ApplyChargingReport) have been requested in a previously sent operation, a SCSM-FSM transition to state "Idle" occurs. Otherwise, if event monitoring has been requested or any report (CallInformationReport and ApplyChargingReport) has been requested, the SCSM-FSM transitions to state "Waiting for Notification or Report". When the 'Connect' operation is used in the context of a hand-off procedure, the SCSM-FSM transitions to state "Idle". However, in this case, the SCF must maintain sufficient information in order to correlate the subsequent 'AssistRequestInstructions' operation (from the assisting SSF or SRF) to the existing SLPI.
+
+### 3.3.16.2.2 Error handling
+
+If reject or error messages are received, then the SCSM informs the SLPI and remains in the state "Preparing SSF Instructions".
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.16.3 Responding Entity (SSF)
+
+#### 3.3.16.3.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) Call origination attempt has been initiated.
+- 2) Basic call processing has been suspended at a DP.
+- 3) The SSF waits for instructions.
+
+SSF Postconditions:
+
+- 1) The SSF performs the call processing actions to route the call to the specified destination.
+- 2) In the O-BCSM, when only address information is included in the Connect operation, call processing resumes at PIC 3.
+- 3) In the O-BCSM, when address information and routing information is included in the Connect operation, call processing resumes at PIC 4.
+
+On receipt of this operation in the SSF-FSM state "Waiting for Instructions", the SSP performs the following actions:
+
+- The SSF cancels  $T_{\text{SSF}}$ .
+- If "cutAndPaste" is present, then the SSF deletes ("cut") from the dialled IN number the indicated number of digits and pastes the remaining dialled digits at the end of the "destinationRoutingAddress" parameter delivered by the SCF. The resulting directory number is used for routing to complete the related call.
+- If "cutAndPaste" is not present, then the "destinationRoutingAddress" parameter delivered by the SCF is used for routing to complete the related call. Note that in the case of hand-off, this results in routing to an assisting SSP or IP.
+- If the "callingPartyNumber" is supplied, this value may be used for all subsequent SSF processing.
+- If no EDPs have been armed and neither a CallInformationReport nor an ApplyChargingReport has been requested, the FSM goes to state "Idle" (e9). Otherwise, the FSM goes to state "Monitoring" (e11).
+
+No implicit activation or deactivation of DPs occurs.
+
+Statistic counter(s) are not affected.
+
+Connect completes when the INAP processing of the operation is complete and before the SSP starts the processing necessary to select a circuit.
+
+Therefore, in order to detect route select failure after a "Connect" it is necessary to explicitly arm the "Route Select Failure" EDP before sending the "Connect" (although they may be in the same message).

+
+#### 3.3.18.1 General description
+
+This operation is used to request the SSF to proceed with call processing at the DP at which it previously suspended call processing to await SCF instructions. The SSF continues call processing without substituting new data from the SCF.
+
+##### 3.3.18.1.1 Parameters
+
+None.
+
+#### 3.3.18.2 Invoking Entity (SCF)
+
+##### 3.3.18.2.1 Normal procedure
+
+SCF Precondition:
+
+- SCSM is in the state "Preparing SSF instructions".
+
+SCF Postcondition:
+
+- SCSM is in the state "Waiting for Notification or Request", in case monitoring was required, or in the state "Idle", in case no monitoring was required.
+
+The SCSM is in state "Preparing SSF instructions". The 'Continue' operation is invoked by a SLPI. This causes a SCSM transition to state "Idle" if no subsequent monitoring is required. However, if monitoring is required, like in the case of armed EDPs or outstanding report requests, the SCSM transitions to state "Waiting for Notification of Report".
+
+##### 3.3.18.2.2 Error handling

+- 2) SSF-FSM is in the state "Waiting for Instructions".
+
+SSF Postconditions:
+
+- 1) BCSM: Basic call processing continues.
+- 2) SSF-FSM is in the state "Monitoring", because at least one EDP was armed, or a 'CallInformationReport' or 'ApplyChargingReport' was requested; or
+
+SSF-FSM is in the state "Idle", because no EDPs were armed and neither the 'CallInformationReport' nor the 'ApplyChargingReport' was requested.
+
+The SSF-FSM is in state "Waiting for instructions". The SSME-Control receives the 'Continue' operation and relays it to the appropriate SSF-FSM. The SSF-FSM transitions to state "Idle" in case no EDPs are armed and no outstanding report requests are present. The SSF-FSM transits to state "Monitoring" if at least one EDP is armed, or if there is at least one outstanding report request. Basic call processing is resumed.

+
+## 3.3.19 DisconnectForwardConnection procedure
+
+### 3.3.19.1 General description
+
+This operation is used in the following two cases:
+
+- 1) To clear a connection to a SRF
+
+This operation is used to explicitly disconnect a connection to a resource (SRF) established previously with a 'ConnectToResource' or an 'EstablishTemporaryConnection' operation. It is used for a forward disconnection from the SSF. An alternative solution is the backward disconnect from the SRF, controlled by the 'DisconnectFromIPForbidden' parameter in the 'PlayAnnouncement' and 'PromptAndCollectUserInfo' operations.
+
+- 2) To clear a connection to an assisting SSF
+
+This operation is sent to the non-assisting SSF of a pair of SSFs involved in an assist procedure. It is used to disconnect the temporary connection between the initiating SSF and the assisting SSF, and the assisting SSF and its associated SRF.
+
+#### 3.3.19.1.1 Parameters
+
+None.
+
+### 3.3.19.2 Invoking Entity (SCF)
+
+#### 3.3.19.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) An assist- or a relay procedure is in progress.
+- 3) An SLPI has determined that a 'DisconnectForwardConnection' operation has to be sent by the SCF.
+
+SCF Postcondition:
+
+- SLPI execution may continue.
+
+The 'DisconnectForwardConnection' operation is used to instruct the SSF to disconnect the concerned forward connection to the assisting SSF or the physical entity containing the SRF.
+
+In the SCSM-FSM state "User Interaction", substate "Waiting for Response from the SRF", this operation is invoked by the SCF when the service logic determines that user interaction is finished and requests the SSF to disconnect the temporary connection to the assisting SSF or the SRF. The SCSM-FSM then transitions to state "Preparing SSF Instructions".
+
+### 3.3.19.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.

+### 3.3.19.3 Responding Entity (SSF)
+
+#### 3.3.19.3.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) Call origination attempt has been initiated.
+- 2) Basic call processing has been suspended at a DP.
+- 3) The initiating SSF is in the state "Waiting for End of User Interaction" or "Waiting for End of Temporary Connection".
+
+SSF Postconditions:
+
+- 1) The connection to the SRF or assisting SSF is released.
+- 2) The SSF is waiting for instructions.
+
+The receipt of "DisconnectForwardConnection" results in disconnecting the assisting SSF or the physical entity containing the SRF from the concerned call. It does not release the connection from the SSF back to the end user.
+
+This operation is accepted in the SSF-FSM states "Waiting for End of Temporary Connection" or "Waiting for End of User Interaction". On receipt of this operation in these states, the SSF must perform the following actions:
+
+- The initiating SSF releases the connection to the assisting SSF or the relay SRF.
+- The SSF resets  $T_{\text{SSF}}$ .
+- The SSF-FSM goes to state "Waiting for Instructions" (e8).
+
+NOTE – The successful disconnection to the SRF causes a state transition in the SRF-FSM to "Idle". A current order ("PlayAnnouncement" or "PromptAndCollectUserInformation") is cancelled and any queued order ("PlayAnnouncement" or "PromptAndCollectUserInformation") is discarded.

+
+### 3.3.20 EstablishTemporaryConnection procedure
+
+#### 3.3.20.1 General description
+
+This operation is used to create a connection between an initiating SSF and an assisting SSF as part of a service assist procedure. It can also be used to create a connection between a SSF and a SRF, for the case where the SRF exists in a separately addressable physical entity.
+
+##### 3.3.20.1.1 Parameters
+
+- assistingSSPIPRoutingAddress:
+
+This parameter indicates the destination address of the SRF for assist procedure. The 'assistingSSPIPRoutingAddress' may contain embedded within it, a 'correlationID' and 'scfID', but only if 'correlationID' and 'scfID' are not specified separately.
+
+- correlationID:
+
+This parameter is used by the SCF to associate the 'AssistRequestInstructions' from the assisting SSF (or the SRF) with the Request from the initiating SSF. The 'correlationID' is used only if the correlation id is not embedded in the 'assistingSSPIPRoutingAddress'. The network operator has to decide about the actual mapping of this parameter on the used signalling system.
+
+- scfID:  
+See Recommendation Q.1290. The 'scfID' is used only if the SCF id is not embedded in the 'assistingSSPIPRoutingAddress'. The network operator has to decide about the actual mapping of this parameter on the used signalling system.
+- carrier:  
+See Recommendation Q.1290. In this message, the carrier selection field is null (00000000) and Carrier ID indicates the carrier to use for the call.
+- serviceInteractionIndicators:  
+This parameter contain indicators sent from the SCP to the SSP for control of the network based services at the originating exchange and the destination exchange.
+
+### 3.3.20.2 Invoking Entity (SCF)
+
+#### 3.3.20.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) The service logic has determined that a connection is needed between the SSF and SRF or between the SSF and an assisting SSF.
+- 3) The call party is not connected to any other party.
+
+SCF Postcondition:
+
+- The SCF is "Waiting for Assist Request Instructions".
+
+In the SCSM-FSM state "Routing to Resource", this operation is invoked by the SCF when the service logic determines that an assisting SSF or a Direct SCF-SRF relation is needed. The SCSM-FSM then transitions to state "Waiting for Assist Request Instructions".

+#### 3.3.20.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.20.3 Responding Entity (SSF)
+
+#### 3.3.20.3.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) Call origination attempt has been initiated.
+- 2) Basic call processing has been suspended at DP 1,2,3,4,5,6,7,12,13,14, or 15.
+- 3) The SSF waits for instructions.
+- 4) The SSF is not an assisting SSF.
+
+SSF Postconditions:
+
+- 1) The SSF performs the call processing actions to route the call to the assisting SSF or SRF according to the 'assistingSSPIPRoutingAddress' requested by the SCF.
+- 2) The SSF waits for end of temporary connection.
+
+On receipt of this operation in the SSF-FSM state "Waiting for Instructions", the SSP has to perform the following actions:
+
+- Reset the  $T_{\text{SSF}}$  (optional).  
+NOTE – This "optional" means that the application timer  $T_{\text{SSF}}$  is optionally set. Whether it is used or not is network operator dependent. But it must be synchronized with  $T_{\text{SCF-SSF}}$  in the SCSM.
+- Route the call to assisting SSF or SRF using 'assistingSSPIPRoutingAddress'.
+- The SSF-FSM goes to state "Waiting for End of Temporary Connection" (e7).
+
+### **3.3.20.3.2 Error handling**
+
+Until the connection set-up has been accepted (refer to Recommendation Q.71) by the assisting SSF-SRF, all received failure indications from the network on the ETC establishment shall be reported to the SCF as ETC error ETCFailed (e.g. busy, congestion). Note that the operation timer for ETC shall be longer than the maximum allowed time for the signalling procedures to accept the connection.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.21 EventNotificationCharging procedure**
+
+#### **3.3.21.1 General description**
+
+This operation is used by the SSF to report to the SCF the occurrence of a specific charging event type as requested by the SCF using the "RequestNotificationChargingEvent" operation. The operation supports the options to cope with the interactions concerning the charging (refer to Appendix II.4/Q.1214 "Charging scenarios").
+
+As several charging events may occur during a connection configuration a possibility exists for the EventNotificationCharging operation to be invoked on multiple occasions. For each connection configuration EventNotificationCharging may be used several times.
+
+#### **3.3.21.1.1 Parameters**
+
+- **eventTypeCharging:**  
+This parameter indicates the charging event type which has occurred. Its content is network operator specific, which may be "charge pulses" or "charge messages".
+- **eventSpecificInformationCharging:**  
+This parameter contains charging related information specific to the event. Its content is network operator specific.
+- **legID:**  
+This parameter indicates the leg id on which the charging event type applies.
+- **monitorMode:**  
+This parameter indicates how the charging event is reported. When the "monitorMode" is "interrupted", the event is reported as a request; if the "monitorMode" is "notifyAndContinue" the event is reported as a notification. The "monitorMode" "transparent" is not applicable for the "EventNotificationCharging" operation.
+
+#### **3.3.21.2 Invoking Entity (SSF)**
+
+##### **3.3.21.2.1 Normal procedure**
+
+SSF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) A charging event has been detected that is requested by the SCF.
+
+SSF Postcondition:
+
+- No FSM state transition.
+
+The SSF-FSM is in any state except "Idle". This operation is invoked if a charging event has been detected that is requested by the SCF. The detected charging event can be caused by:
+
+- a) another SLPI; or
+- b) another exchange.
+
+Irrespective of the charging event cause, the SSF performs one of the following actions on occurrence of the charging event (according the corresponding monitorMode):
+
+**Interrupted:**
+
+- Notify the SCF of the charging event using "EventNotificationCharging" operation: do not process the event, but discard it. However, call and existing charging processing will not be suspended in the SSF.
+
+**NotifyAndContinue:**
+
+- Notify the SCF of the charging event using "EventNotificationCharging", and continue processing the event or signal.
+
+**3.3.21.2.2 Error handling**
+
+Operation related error handling is not applicable, due to class 4 operation.
+
+**3.3.21.3 Responding Entity (SCF)****3.3.21.3.1 Normal procedure**
+
+SCF Precondition:
+
+- A "RequestNotificationChargingEvent" has been sent at the request of a SLPI and the SLPI is expecting an "EventNotificationCharging" from the SSF.
+
+SCF Postcondition:
+
+- No FSM state transition.
+
+On receipt of this operation the SLPI which is expecting this notification can continue. If the corresponding monitor mode was set by the SLPI to Interrupted, the SLPI prepares instructions for the SSF if necessary.
+
+**3.3.21.3.2 Error handling**
+
+Operation related error handling is not applicable, due to class 4 operation.
+
+**3.3.22 EventReportBCSM procedure****3.3.22.1 General description**
+
+This operation is used to notify the SCF of a call related event previously requested by the SCF in an 'RequestReportBCSMEVENT' operation. The monitoring of more than one event could be requested with a 'RequestReportBCSMEVENT' operation, but each of these requested events is reported in a separate 'EventReportBCSM' operation.
+
+**3.3.22.1.1 Parameters**
+
+- eventTypeBCSM:
+
+This parameter specifies the type of event that is reported.
+
+- bcsmeventCorrelationID:
+
+Used by the SCF for correlation with a previous operation.
+
+- eventSpecificInformationBCSM:
+
+This parameter indicates the call related information specific to the event.
+
+For 'CollectedInfo' it will contain the 'calledPartyNumber'.
+
+For 'AnalysedInfo' it will contain the 'calledPartyNumber'.
+
+For 'RouteSelectFailure' it will contain the 'FailureCause', if available.
+
+For O- or T-Busy it will contain the 'BusyCause', if available.
+
+For O- or T-NoAnswer it will be empty.
+
+For O- or T-Answer it will be empty.
+
+For O- or T-MidCall it will contain 'connectTime', if available.
+
+For O- or T-Disconnect it will contain the 'releaseCause' and/or 'connectTime', if available.
+
+The connect time, if available, indicates the duration between the received answer indication from the called party side and the release of the connection in units of 100 ms.
+
+- legID:
+
+This parameter indicates the party in the call for which the event is reported. SSF will use the option 'ReceivingSideID' only.
+
+- receivingSideID:
+
+The following values for 'legID' are assumed:
+
+- 'legID' = 1 indicates the party that was present at the moment of the 'InitialDP' or a DP-specific operation (in case of a midcall trigger, the party causing the trigger), or the party that was created with an 'InitiateCallAttempt' operation.
+- 'legID' = 2 indicates the party that was created with a 'Connect' operation, or in case of a mid call trigger, the party not causing the trigger.
+
+If not included, the following defaults are assumed:
+
+- legID = 1 for the events CollectedInfo, AnalysedInformation, O-Abandon and T-Abandon.
+- legID = 2 for the events RouteSelectFailure, O-CalledPartyBusy, O-NoAnswer, O-Answer, T-Busy, T-NoAnswer and T-Answer.
+
+The 'legID' parameter shall always be included for the events O-MidCall, O-Disconnect, T-MidCall and T-Disconnect.
+
+- miscCallInfo:
+
+This parameter indicates detection point related information.
+
+- messageType:
+
+This parameter indicates whether the message is a request, i.e. resulting from a 'RequestReportBCSMEVENT' with 'monitorMode' = 'interrupted', or a notification, i.e. resulting from a 'RequestReportBCSMEVENT' with 'monitorMode' = 'notifyAndContinue'.
+
+- dPAssignment:
+
+This parameter shall be omitted for this operation.
+
+### 3.3.22.2 Invoking Entity (SSF)
+
+#### 3.3.22.2.1 Normal procedure
+
+SSF Preconditions:
+
+- The SSF-FSM is in the state "Monitoring"; or  
+the SSF-FSM may be in state "Waiting for Instructions" if the O/TDisconnect DP is armed and encountered; or  
+the SSF-FSM may be in any state if the O/TAbandon DP is armed and encountered.
+- The BCSM proceeds to an EDP that is armed.
+
+SSF Postconditions:
+
+- The SSF-FSM stays in the state "Monitoring" if the message type was notification and there are still EDPs armed or a "CallInformationReport" or "ApplyChargingReport" requested.
+- The SSF-FSM moves to the state "Idle" if the message type was notification and there are no more EDPs armed, no "CallInformationReport" or "ApplyChargingReport" are requested.
+- The SSF-FSM moves to the state "Waiting for Instructions" if the message type was request. Call processing is interrupted.
+
+For certain service features it is necessary that the same O-BCSM instance is reused. Examples are follow-on calls.
+
+The decision to reuse the same O-BCSM instance can only be taken by the SCF after certain armed EDP-R's are reported.
+
+The considered EDP-R's are:
+
+- RouteSelectFailure;
+- O\_CalledPartyBusy;
+- O\_NoAnswer;
+- O\_Disconnect.
+
+If a EDP-R is met that causes the release of the related leg, all EDPs related to that leg are disarmed and the event is reported via "EventReportBCSM". To allow the reuse of the same O-BCSM instance, the BCSM has to store all call related signalling parameters (e.g. "callingPartyNumber", "callingPartyCategory") until the BCSM instance is released.
+
+In the case the respective EDP-R is met (see list above with "O-Disconnect" only for legID = 2), the A-leg will be held, the B-leg will be released and the SCF is informed via "EventReportBCSM".
+
+If the A-party disconnects, the call is released whether or not a DP was armed.
+
+### **3.3.22.2.2 Error handling**
+
+In case the message type is request, on expiration of  $T_{SSF}$  before receiving any operation, the SSF aborts the interaction with the SCF and the call is given final treatment, e.g. a final announcement.
+
+Operation related error handling is not applicable, due to class 4 operation.

+
+### **3.3.23 FurnishChargingInformation procedure**
+
+#### **3.3.23.1 General description**
+
+This operation is used to request the SSF to generate, register a call record or to include some information in the default call record. The registered call record is intended for off-line charging of the call. A possibility exists for the FurnishChargingInformation (FCI) operation to be invoked on multiple occasions. FCI could be applied at the beginning of the call in order to request to start call record generation. In addition FCI can also be applied at the end of the call or connection configuration (e.g. for follow-on calls). In this case FCI is used to include charge related information into the
+
+call record which was started at the beginning of the call. When additional FCIs are used it is recommended to arm an EDP-R (indicating the end of call or connection configuration) to be able to apply FCI before the termination of the call record generation. The charging scenarios supported by this operation are: 2.2, 2.3 and 2.4 (refer to Appendix II/Q.1214, "Charging scenarios").
+
+#### 3.3.23.1.1 Parameters
+
+- FCIBillingChargingCharacteristics:
+
+This parameter indicates billing and/or charging characteristics. Its content is network operator specific. Depending on the applied charging scenario, the following information elements can be included (refer to Appendix II/Q.1214, "Charging scenarios"):
+
+- complete charging record (scenario 2.2);
+- charge party (scenario 2.3);
+- charge level (scenario 2.3);
+- charge items (scenario 2.3);
+- correlationID (scenario 2.4).
+
+#### 3.3.23.2 Invoking Entity (SCF)
+
+##### 3.3.23.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) An SLPI has determined that a "FurnishChargingInformation" has to be sent by the SCF.
+
+SCF Postconditions:
+
+- 1) No FSM state transition.
+- 2) SLPI execution may continue.
+
+The SCSM-FSM is in state "Preparing SSF instruction" or is in state "Queueing FSM". This operation is invoked by the SCF if a SLPI results in the request of creating a call record to the SSF or to include some billing or charging information into the default call record. In the case of call queueing, this operation may contain information pertaining to the initiation of queueing or the call queueing time duration for call logging purpose. This causes no SCSM-FSM state transition.
+
+##### 3.3.23.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+#### 3.3.23.3 Responding Entity (SSF)
+
+##### 3.3.23.3.1 Normal procedure
+
+SSF Preconditions:
+
+- SSF-FSM: State c, "Waiting for Instructions"; or  
+SSF-FSM: State d, "Waiting for End of User Interaction"; or  
+SSF-FSM: State e, "Waiting for End of Temporary Connection"; or  
+SSF-FSM: State f, "Monitoring"; or  
+Assisting/hand-off SSF-FSM State b, "Waiting for Instructions".
+
+SSF Postcondition:
+
+- No FSM state transition.
+
+On receipt of this operation, the SSF performs actions to create the call record according the off line charging scenario which is applicable using the information elements included in the operation:
+
+- registers the complete call record included in the operation;
+- generates and registers a call record according the information (charge party, charge level, charge items);
+- include the information received "correlationID" in the default call record which is generated and, registered by default at the SSF.
+
+By means of a parameter at the "FurnishChargingInformation" operation the SCF can initiate the pulse metering function of the SSF.
+
+In that case the SSF shall generate meter pulses according to the applicable charging level, account and record them.
+
+The SSF records charge related data like for example the call duration, begin time stamp or end time stamp. Additionally the SSF records further data if required.
+
+The charging level can be determined by:
+
+- a) the SCF; or
+- b) the SSF; or
+- c) a succeeding exchange; or
+- d) the post processing function.
+
+If a) applies, the charging level is included in the "FurnishChargingInformation" operation.
+
+If b) applies, the SSF shall determine the charging level based on the corresponding parameters contained in the operation.
+
+If c) applies, either the "FurnishChargingInformation" operation contains the corresponding parameters indicating that the charging level shall be determined in a succeeding exchange, or the SSF detects during the determination of the charging level based on the provided parameters that the charging level shall be determined in a succeeding exchange.
+
+The SSF can either account received pulses or convert any charging messages received from the B-side to pulses. In both cases, the accumulated pulses are included when the IN call record is generated or ignored.

+
+This operation is sent by the SSF after detection of a TDP-R in the BCSM, to request the SCF for instructions to complete the call.
+
+##### **3.3.25.1.1 Parameters**
+
+- serviceKey:
+
+This parameter identifies for the SCF unambiguously the requested IN service. It is used to address the correct application/SLP within the SCF (not for SCP addressing).

+See Recommendation Q.1290.
+
+- iPAvailable:
+
+See Recommendation Q.1290.
+
+- locationNumber:
+
+This parameter is used to convey the geographical area address for mobility services, see Recommendation Q.762.

+- additionalCallingPartyNumber:
+
+The calling party number provided by the access signalling system of the calling user, e.g. provided by a PBX.
+
+- forwardCallIndicators:
+
+This parameter indicates if the call shall be treated as a national or international call. It also indicates the signalling capabilities of the network access, preceding network connection and the preferred signalling capabilities of the succeeding network connection. The network access capabilities does not indicate the terminal type. For example, an ISPBX will have an ISDN type of access, but the end user terminal behind the ISPBX may be ISDN or non-ISDN.
+
+- bearerCapability:
+
+This parameter indicates the type of the bearer capability connection or the transmission medium requirements to the user. It is a network option to select one of the two parameters to be used:
+
+- bearerCap:
+
+This parameter contains the value of the DSS-1 Bearer Capability parameter (see Recommendation Q.931) in case the SSF is at local exchange level or the value of the ISUP User Service Information parameter (see Recommendation Q.763) in case the SSF is at transit exchange level.
+
+The parameter 'bearerCapability' shall only be included in the 'InitialDP' operation in case the DSS-1 Bearer Capability parameter or the ISUP User Service Information parameter is available at the SSP.
+
+If two values for bearer capability are available at the SSF or if User Service Information and User Service Information Prime are available at the SSF, the 'bearerCap' shall contain the value of the preferred bearer capability respectively the value of the User Service Information Prime parameter.

+
+See Q.763 Redirection Information signalling information.
+
+### 3.3.25.2 Invoking Entity (SSF)
+
+#### 3.3.25.2.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) An event fulfilling the criteria for the DP being executed has been detected.
+- 2) Call gapping and SS No. 7 overload are not in effect for the call, and the call is not to be filtered.
+
+SSF Postconditions:
+
+- 1) A control relationship has been established if the DP was armed as a TDP-R. The SSF-FSM moves to the state "Waiting for Instructions".
+- 2) The SSF-FSM remains in the state "Idle" if the DP was armed as a TDP-N.
+
+Following a trigger detection (due to the DP criteria assigned being met) related to an armed TDP in the BCSM caused by a call origination attempt, the SSF checks if call gapping, SS No. 7 overload or service filtering are not in effect for the related call segment.
+
+If these conditions are met, then the 'InitialDP' operation is invoked by the SSF. The address of the SCF the 'InitialDP' operation has to be sent to, is determined on the base of trigger related data. The SSF provide as many parameters as available. In some cases, some parameters must be available (such as 'callingPartyNumber' or 'callingPartyCategory'). This is to be handled appropriately by the SSF in its trigger table (to know that such parameters are necessary for some triggering conditions) and in conducting the necessary action to get these parameters if they are not available (for instance if non-SS No. 7 signalling is used, it may be possible to request the 'callingPartyCategory' from a preceding exchange).
+
+Otherwise, the call control is given back to the underlying network.
+
+If the DP was armed as a TDP-R, a control relationship is established to the SCF. The SSF application timer  $T_{\text{SSF}}$  is set when the SSF sends 'InitialDP' for requesting instructions from the SCF. It is used to prevent excessive call suspension time.
+
+#### 3.3.25.2.2 Error handling
+
+If the destination SCF is not accessible, then the call is given final treatment.
+
+On expiration of  $T_{\text{SSF}}$  before receiving any operation, the SSF aborts the interaction with the SCF and the call is given final treatment, e.g. routing to a final announcement.
+
+If the calling party abandons after the sending of 'InitialDP', then the SSF aborts the control relationship by means of an abort to TCAP. Note that TCAP will wait until the first response message from the SCF has been received before it sends an abort to the SCF (see also 3.2).
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.25.3 Responding Entity (SCF)
+
+#### 3.3.25.3.1 Normal procedure
+
+SCF Precondition:
+
+- None.
+
+SCF Postcondition:
+
+- An SLPI has been invoked.
+
+On receipt of 'InitialDP' operation the SCSM moves from "Idle" to the state "Preparing SSF Instructions", a control relationship to the related SSF is created. A Service Logic Program Instance (SLPI) is invoked for processing the 'InitialDP' operation based on the 'serviceKey' parameter. By means of this control relationship, the SCF may influence the Basic Call Processing in accordance with the service logic invoked.
+
+The actions to be performed in the SLPI depend on the parameters conveyed via this operation and the SLPI, i.e. the requested IN service itself.
+
+### **3.3.25.3.2 Error handling**
+
+If the 'InitialDP' operation is rejected, then the SCSM remains in "Idle". The maintenance function is informed and no SLPI is invoked.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+## **3.3.26 InitiateCallAttempt procedure**
+
+### **3.3.26.1 General description**
+
+This operation is used to request the SSF to create a new call to one call party using the address information provided by the SCF (e.g. wake-up call). An EDP-R must be armed on answer and all the call failure events, in order to have the SCF, treat this call appropriately when either of these events is encountered.
+
+#### **3.3.26.1.1 Parameters**
+
+- destinationRoutingAddress:
+
+This parameter contains the called party number towards which the call is to be routed. The destinationRoutingAddress may contain one called party number only for this operation. The encoding of the parameter is defined in Recommendation Q.763.
+
+- alertingPattern:
+
+See Recommendation Q.1290. It only applies if the network signalling supports this parameter or if SSF is the terminating local exchange for the subscriber.
+
+- iSDNAcessRelatedInformation:
+
+Carries the same information as the protocol element ISUP Access Transport parameter in Recommendation Q.762.
+
+- travellingClassMark:
+
+The SCF uses the travellingClassMark parameter to provide essential route selection information to the SSF. The SSF uses this information to populate the outgoing ISUP-IAM message, the population and mapping of this parameter is network operator specific.
+
+- serviceInteractionIndicators:
+
+This parameter contains indicators sent from the SCF to the SSF for control of the network based services at the originating exchange and the destination exchange.
+
+- callingPartyNumber:
+
+This parameter identifies which number shall be regarded as the calling party for the created call. If this parameter is not sent by the SCF, the SSF may supply a network dependent default value.
+
+### **3.3.26.2 Invoking Entity (SCF)**
+
+#### **3.3.26.2.1 Normal procedure**
+
+SCF Preconditions:
+
+- 1) An SLPI has been invoked, no control relationship exists between SCF and SSF.
+- 2) An SLPI has determined that an 'InitiateCallAttempt' operation should be sent to the SCF.
+- 3) The SCSM-FSM is in state "Idle".
+
+SCF Postconditions:
+
+- 1) A control relationship is established between the SCF and SSF.
+- 2) The SCSM-FSM is in state "Preparing SSF Instructions".
+- 3) SLPI execution continues.
+
+The SCSM-FSM moves to state "Preparing SSF Instructions" when the service logic invokes this operation. In order to enable the establishment of a control relationship between the SCF and SSF and to allow the SCF to control the created call appropriately, the SLPI shall monitor for the BCSM event(s) which report the result of the created call set-up. This includes DP 3 or DP 4, 5, 6, and 7. Any other Non-Call\_Processing\_Instructions may be sent as well. The 'InitiateCallAttempt' operation creates a BCSM instance in the SSF but the SSF suspends the call processing of this BCSM. The SLPI shall send a 'Continue' operation to request the SSF to route the call to the specified destination. The SCSM-FSM shall proceed as specified at the procedure for the 'Continue' operation.
+
+The above described procedure shall be part of the establishment of the control relationship, i.e. operations up to and including the 'Continue' operation shall be sent together in the same message to the SSF. The SCF shall start a response Timer  $T_{SCF}$  when the 'InitiateCallAttempt' operation is sent. The response Timer shall supervise the confirmation of the dialogue from SSF, the value of  $T_{SCF}$  shall be equal or less than the network no answer timer.
+
+### 3.3.26.2.2 Error handling
+
+On expiration of  $T_{SCF}$  the SCF shall abort the dialogue, report the abort to the maintenance functions and inform the SLPI on the failure of dialogue establishment. The SCSM-FSM moves to the "Idle" state.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.

+- 1) A new originating BCSM has been created, call processing is suspended at DP 1.
+- 2) The SSF-FSM has moved from "Idle" state to state "Waiting for Instructions".
+
+Upon reception of 'InitiateCallAttempt', the SSF creates a new originating BCSM and suspends the call processing of this BCSM at DP 1. All subsequent operations are treated according to their normal procedures.
+
+The properties and capabilities, normally received from or associated to the calling party, required for the call set-up shall have a network dependent default value. If a calling party number is supplied by the SCF, these properties may be dependent on the received calling party number

+
+### 3.3.27 ModifyEntry procedure
+
+#### 3.3.27.1 General description
+
+The X.500 'ModifyEntry' operation is used to request the SDF to make one or several modifications to a data object. The modifications concern the attributes and their values of which the object is composed. The type of modifications to perform is given in the operation argument provided by the SCF. The modifications do not concern the values of the attributes used to identify the object (i.e. the object name). For a full description of the ModifyEntry operation, see 11.3/X.511.
+
+### 3.3.27.1.1 Parameters
+
+See 11.3.2/X.511 and 11.3.3/X.511.
+
+### 3.3.27.2 Invoking Entity (SCF)
+
+#### 3.3.27.2.1 Normal procedure
+
+SCF Precondition:
+
+- SCSM: "SDF Bound" or "Wait for Subsequent Requests".
+
+SCF Postcondition:
+
+- SCSM: "SDF Bound".
+
+When the SCSM is in the state "Wait for Subsequent Requests" and a need of the service logic to modify information of the SDF exists, an internal event [(e2) Request\_to\_SDF] occurs. Until the application process indicates, with a delimiter (or a timer expiry), that the operation should be sent, the SCSM remains in the state "Wait for Subsequent Requests" and the operation is not sent. The operation is sent to the SDF in a message containing a Bind argument. The SCSM waits for the response from the SDF. The reception of the response [(E5) Response\_from\_SDF\_with\_Bind or (E4) Bind\_Error] to the Bind operation previously issued to the SDF causes a transition of the SCF to the state "SDF Bound" or to the state "Idle". When the SCSM has moved to state "Idle", the ModifyEntry operation was discarded. In the state "SDF Bound", the response of the ModifyEntry operation [(E7) Response\_from\_SDF] causes a transition of the SCF to the same state ("SDF Bound"). It may be either the result of the ModifyEntry operation or an error.
+
+When the SCSM is in the state "SDF Bound" and a need of the service logic to modify information of the SDF exists, an internal event occurs. This event, called (e6) Request\_to\_SDF causes a transition to the same state "SDF Bound" and the SCSM waits for the response from the SDF. The reception of the response [(E7) Response\_from\_SDF] to the ModifyEntry operation previously issued to the SDF causes a transition of the SCF to the same state "SDF Bound". The response from the SDF may be either the result of the ModifyEntry operation or an error.
+
+#### 3.3.27.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 11.3.4/X.511 and 11.3.5/X.511 and the TCAP services that are used for reporting operating errors are described in 2.2.2.

+#### 3.3.27.3.1 Normal procedure
+
+SDF Precondition:
+
+- SDSM: "SCF Bound" or "Bind Pending".
+
+SDF Postcondition:
+
+- SDSM "SCF Bound".
+
+When the SDF is in the state "Bind Pending", the external event (E3) Request\_from\_SCF caused by the reception of a 'ModifyEntry' operation from the SCF occurs. The SDF does not proceed to the operation until a Bind operation has been successfully executed. It remains in the same state.
+
+When the SDF is in the state "SCF Bound", the external event (E7) Request\_from\_SCF caused by the reception of a 'ModifyEntry' operation from the SCF occurs. The SDF waits for the response to the operation.
+
+On the receipt of the event (E7) and before updating the different attributes specified in the operation parameters, the SDF shall take the following actions:
+
+- verify that the object accessed by the request exists;
+- verify that the user on behalf of whom the request is performed has sufficient access rights to modify the object for each elementary modifications contained in the operation;
+- verify that each attribute or value on which an operation should be performed exists in the object;
+- verify that the proposed modifications are compatible with the object class of the object or with the syntax of the attribute.
+
+After the specified actions, indicated above, are successfully executed for all the modifications requested in the operation, all the modifications for a same attribute take place in the order given in the "changes" parameter. A result is returned to the SCF. The sending of the result corresponds to the event (e6) Response\_to\_SCF.

+
+### 3.3.31.2 Invoking Entity (SSF)
+
+#### 3.3.31.2.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) Call processing has progressed through the O\_Null and Authorize Origination Attempt PIC of the O-BCSM and the call origination attempt has been authorized.
+- 2) Call gapping and SS No. 7 overload are not in effect for the call, and the call is not to be filtered.
+- 3) A trigger is armed as a TDP at the Origination\_Attempt\_Authorized detection point.
+
+SSF Postconditions:
+
+- 1) For TDP-R, a control relationship has been established and the SSF waits for instructions from the SCF.
+- 2) For TDP-N, call processing continues at the Collect\_Info PIC.
+
+#### 3.3.31.2.2 Error handling
+
+If the destination SCF is not accessible, then the call is given final treatment (other treatments are for further study). On expiration of  $T_{\text{SSF}}$  before receiving any operation, the SSF aborts the interaction with the SCF and the call is given final treatment (e.g. routing to a final announcement). If the calling party abandons after the sending of the OriginationAttemptAuthorized operation, then the SSF aborts the control relationship after the first answer message from the SCF has been received: the Transaction ID is held open until  $T_{\text{SSF}}$  expires.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.31.3 Responding Entity (SCF)
+
+#### 3.3.31.3.1 Normal procedure
+
+SCF Precondition:
+
+- No control relationship exists.
+
+SCF Postconditions:
+
+- 1) An SLPI has been invoked; a control relationship is established for TDP-R.
+- 2) For TDP-N: None.
+
+On receipt of the OriginationAttemptAuthorized operation, the SCSM moves from "Idle" state to the state "Preparing SSF Instructions". A control relationship to the related SSF is created. A Service Logic Program Instance (SLPI) is invoked for processing the OriginationAttemptAuthorized operation. By means of this control relationship, the SCF may influence the Basic Call Processing in accordance with the service logic invoked. The actions to be performed in the SLPI depend on the parameters conveyed via this operation and the SLPI (i.e. the requested IN service itself).
+
+#### 3.3.31.3.2 Error handling
+
+If the OriginationAttemptAuthorized operation is rejected, then the SCSM remains in the same state. The maintenance function is informed and no SLPI is invoked. Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.32 PlayAnnouncement procedure
+
+#### 3.3.32.1 General description
+
+This operation is used for inband interaction with an analogue user or for interaction with an ISDN user.
+
+##### 3.3.32.1.1 Parameters
+
+- informationToSend:
+
+This parameter indicates an announcement, a tone or display information to be sent to the end user by the SRF.
+
+- a) inbandInfo:
+
+This parameter specifies the inband information to be sent.
+
+- messageID:
+
+This parameter indicates the message(s) to be sent, this can be one of the following:
+
+- i) elementaryMessageID:
+
+This parameter indicates a single announcement.
+
+- ii) text:
+
+This parameter indicates a text to be sent. The text shall be transformed to inband information (speech) by the SRF. This parameter consists of two subparameters, messageContent and attributes. The attributes of text may consist of items such as language.
+
+- iii) elementaryMessageIDs:
+
+This parameter specifies a sequence of announcements.
+
+- iv) variableMessage:
+
+This parameter specifies an announcement with one or more variable parts.
+
+- numberOfRepetitions:
+
+This parameter indicates the maximum number of times the message shall be sent to the end-user.
+
+- duration:
+
+This parameter indicates the maximum time duration in seconds that the message shall be played/repeated. ZERO indicates endless repetition.
+
+- interval:
+
+This parameter indicates the time interval in seconds between repetitions, i.e. the time between the end of the announcement and the start of the next repetition. This parameter can only be used when the number of repetitions is > 1.
+
+- b) tone:
+
+This parameter specifies a tone to be sent to the end-user.
+
+- toneID:
+
+This parameter indicates the tone to be sent.
+
+- duration:
+
+This parameter indicates the time duration in seconds of the tone to be sent. ZERO indicates infinite duration.
+
+- c) displayInformation:
+
+This parameter indicates a text string to be sent to the end-user. This information can not be received by a PSTN end-user.
+
+NOTE – As the current signalling systems (DSS-1/ISUP) do not provide an indication whether or not information can be displayed by the user's terminal, in case of user interaction with an ISDN user two consecutive 'PlayAnnouncement' operations are sent. The first contains the display information, the second contains the inband information to be sent to the user. Since the execution of the display information by the SRF should take a limited amount of time, the inband information will be immediately sent by the SRF to the user, in sequence with the display information.
+
+- disconnectFromIPForbidden:
+
+This parameter indicates whether or not the SRF should be disconnected from the user when all information has been sent.
+
+- requestAnnouncementComplete:
+
+This parameter indicates whether or not a 'SpecializedResourceReport' shall be sent to the SCF when all information has been sent.
+
+### 3.3.32.2 Invoking Entity (SCF)

+- 2) The SRSM-FSM moves to the state "User Interaction" or remains in the same state.
+- 3) If all information has been sent and "RequestAnnouncementComplete" was set TRUE, the SRSM sends a "SpecializedResourceReport" operation to the SCF.
+- 4) If all information has been sent and "disconnectFromIPForbidden" was set FALSE, the SRSM disconnects the SRF from the user.
+
+The announcement send to the end-user is ended in the following conditions:
+
+- if neither "duration" or "numberOfRepetitions" is specified, then the network specific announcement ending conditions shall apply; or
+- if "numberOfRepetitions" is specified, when all repetitions have been sent; or
+- if duration is specified, when the duration has expired. The announcement is repeated until this condition is met; or
+- if "duration" and "numberOfRepetitions" is specified, when one of both conditions is satisfied (whatever comes first).
+
+### 3.3.32.3.2 Error handling
+
+If a Cancel operation is received before or during the processing of the operation, then the operation is immediately cancelled and the error "Cancelled" is reported to the invoking entity.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.33 PromptAndCollectUserInformation procedure
+
+#### 3.3.33.1 General description
+
+This operation is used to interact with a call party in order to collect information.
+
+##### 3.3.33.1.1 Parameters
+
+a) collectedInfo
+
+i) collectedDigits
+
+• minimumNbOfDigits:
+
+If this parameter is missing, the default value is defined to be 1. The "minimumNbOfDigits" specifies the minimum number of valid digits to be collected.
+
+• maximumNbOfDigits:
+
+This parameter should always be present and specifies the maximum number of valid digits to be collected. The following applies: "maximumNbOfDigits" >= "minimumNbOfDigits".
+
+• endOfReplyDigit:
+
+This parameter indicates the digit used to signal the end of input.
+
+In case the "maximumNbOfDigits" = "minimumNbOfDigits", the "endOfReplyDigit" (could be present but) has no further meaning. This parameter can be one or two digits.
+
+In case the "maximumNbOfDigits" > "minimumNbOfDigits", the following applies:
+
+- If "endOfReplyDigit" is not present, the end of input is indicated:
+  - 1) when the inter-digit timer expires; or
+  - 2) when the number of valid digits received equals the "maximumNbOfDigits".
+- If "endOfReplyDigit" is present, the end of input is indicated:
+  - 1) when the inter-digit timer expires; or
+  - 2) when the end of reply digit is received; or
+  - 3) when the number of valid digits received equals the "maximumNbOfDigits".
+
+When the end of input is attained, the collected digits are sent from SRF to the SCF, including the "endOfReplyDigit" if received by the SRF.
+
+In the case the number of valid digits received is less than the "minimumNbOfDigits" when the inter-digit timer expires or when the end of reply digit is received, the input is specified as being erroneous.
+
+• cancelDigit:
+
+If this parameter is present, the cancel digit can be entered by the user to request a possible retry. All digits already received by the SRF are discarded and the same "PromptAndCollectInformation" procedure is performed again, thus, e.g. the same announcement to request user information is given to the user and information is collected. This parameter can be one or two digits .
+
+If this parameter is not present, the user is not able to request a possible retry.
+
+- startDigit:
+
+If this parameter is present, the start digit indicates the start of the valid digits to be collected. The digits that are received by the SRF before this start digit is received, are discarded and are not considered to be valid. This parameter can be one or two digits.
+
+If this parameter is not present, all received digits are considered to be valid.
+
+- firstDigitTimeout:
+
+If this parameter is present, the first digit should be received by the SRF before the first-digit timer expiration. In case the first digit is not received before first-digit timer expiration, the input is regarded to be erroneous. After receipt of the first valid or non-valid input digit, the corresponding first-digit timer is stopped.
+
+If this parameter is not present, then the SRF uses a default value (network operator specific) for the first-digit timer in which the first valid or non-valid input digit is received.
+
+If "startDigit" is present, the first-digit timer is stopped after the start digit is received.
+
+- interDigitTimeOut:
+
+If this parameter is present any subsequent valid or non-valid digit should be received by the SRF before the inter-digit timer expires. As result the inter-digit timer is reset and restarted.
+
+In case a subsequent valid or non-valid digit is not received before the inter-digit timer expires and the number of received valid digits is less than the "minimumNbOfDigits", the input is regarded to be unsuccessful.
+
+In case a subsequent valid or non-valid digit is not received before the inter-digit timer expires and the number of received valid digits is greater than the "minimumNbOfDigits", and less than or equal to the "maximumNbOfDigits", the input is regarded to be successful.
+
+If the "interDigitTimeOut" is not present, then the SRF uses a default value for the inter-digit time.
+
+- errorTreatment:
+
+This optional parameter defines what specific action should be taken by the SRF in the event of error conditions occurring. The default value is reportErrorToSCF.
+
+- interruptableAnnInd:
+
+This parameter is optional, where the default value is specified being TRUE.
+
+If this parameter is TRUE, the announcement is interrupted after the first valid or non-valid digit is received by the SRF. If the announcement is interrupted, a possible start-digit timer will not apply anymore. However, if the announcement has not been interrupted, a possible start-digit timer is started after the announcement has been finished.
+
+If this parameter is present and explicitly set to FALSE, the announcement will not be interrupted after the first digit is received by the SRF. The received digits during the announcement are discarded and considered to be non-valid. All other specified parameters ("minimumNbOfDigits", "maximumNbOfDigits", "endOfReplyDigit", etc.) do not apply before the announcement has been finished. The possible start-digit timer is started after the announcement has been finished.
+
+- voiceInformation:
+
+This parameter is optional, where the default value is specified being FALSE. If the "voiceInformation" parameter is FALSE, all valid or non-valid digits are entered by DTMF.
+
+If this parameter is present and explicitly set to TRUE, calling user is required to provide all valid or non-valid information by speech. The SRF will perform voice recognition and translation of the provided information into digits. A possible end of reply digit will also have to be provided by speech.
+
+- voiceBack:
+
+This parameter is optional, where the default value is specified being FALSE. If the "voiceBack" parameter is FALSE, no voice back information is given by the SRF.
+
+If this parameter is present and explicitly set to TRUE, the valid input digits received by the SRF will be announced back to the calling user immediately after the end of input is received. The non-valid input digits will not be announced back to the calling user.
+
+A possible end of reply digit is not voiced back.
+
+- b) disconnectFromIPForbidden:
+
+This parameter indicates whether the SRF should initiate disconnection to the SSF-CCF after the interaction has been completed. If the parameter is not present or set to TRUE, the SRF shall not initiate disconnection.
+
+- c) informationToSend:
+
+This parameter indicates an announcement, a tone or display information to be sent to the end user by the SRF.
+
+- i) inbandInfo:
+
+This parameter specifies the inband information to be sent.
+
+- messageID:
+
+This parameter indicates the message(s) to be sent, this can be one of the following:
+
+- elementaryMessageID:
+
+This parameter indicates a single announcement.
+
+- text:
+
+This parameter indicates a text to be sent. The text shall be transformed to inband information (speech) by the SRF. This parameter consist of two subparameters, messageContent and attributes. The attributes of text may consist of items such as language.
+
+- elementaryMessageIDs:
+
+This parameter specifies a sequence of announcements.
+
+- variableMessage:
+
+This parameter specifies an announcement with one or more variable parts.
+
+- numberOfRepetitions:
+
+This parameter indicates the maximum number of times the message shall be sent to the end-user.
+
+- duration:
+
+This parameter indicates the maximum time duration in seconds that the message shall be played/repeated. ZERO indicates endless repetition.
+
+- interval:
+
+This parameter indicates the time interval in seconds between repetitions, i.e. the time between the end of the announcement and the start of the next repetition. This parameter can only be used when the number of repetitions is > 1.
+
+- ii) tone:
+
+This parameter specifies a tone to be sent to the end-user.
+
+- toneID:
+
+This parameter indicates the tone to be sent.
+
+- duration:
+
+This parameter indicates the time duration in seconds of the tone to be sent. ZERO indicates infinite duration.
+
+iii) displayInformation:
+
+This parameter indicates a text string to be sent to the end-user. This information can not be received by a PSTN end-user.
+
+NOTE – As the current signalling systems (DSS 1/ISUP) do not provide an indication whether or not information can be displayed by the user's terminal, in case of user interaction with an ISDN user, the 'displayInformation' parameter is not used in the 'PromptAndCollectUserInfoInformation' operation. Instead, a 'PlayAnnouncement' operation containing the 'displayInformation' parameter followed by a 'PromptAndCollectUserInfoInformation' operation containing inband information are sent to the user. Since the execution of the displayed information by the SRF should take a limited amount of time, the inband information will be immediately sent after by the SRF to the user, in sequence with the displayed information.
+
+– digitsResponse:
+
+This parameter contains the information collected from the end-user.
+
+### 3.3.33.2 Invoking Entity (SCF)
+
+#### 3.3.33.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) The SLPI detects that information should be collected from the end-user.
+- 2) A connection between the end-user and a SRF has been established.
+- 3) The SCSM-FSM is in state "User Interaction", substate "Waiting for Response from the SRF".
+
+SCF Postconditions:
+
+- 1) The collected information is received from the SRF as response to the 'PromptAndCollectUserInfoInformation' operation.
+- 2) If the 'disconnectFromIPForbidden' was set to FALSE, the SCSM-FSM will move to the state "Preparing SSF Instructions".
+- 3) Otherwise the SCSM-FSM remains in the same state.
+
+The SLPI may continue execution before the response is received from the 'PromptAndCollectUserInfoInformation' operation, more than one operation may be sent to the SRF before the response is received. The 'disconnectFromIPForbidden' parameter may only be set to FALSE if the 'PromptAndCollectUserInfoInformation' operation is the last operation sent to the SRF.
+
+#### 3.3.33.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### 3.3.33.3 Responding Entity (SRF)
+
+#### 3.3.33.3.1 Normal procedure
+
+SRF Precondition:
+
+- The SRSM-FSM is in the state "Connected", or in state "User Interaction" if the SRF received previously an operation from the SCF.
+
+SRF Postconditions:
+
+- 1) The SRF has sent the information to the end-user as indicated by "informationToSend".
+- 2) The collected information from the end-user is sent to the SCF as RETURN RESULT of the "PromptAndCollectUserInfoInformation".
+- 3) If the "disconnectFromIPForbidden" was set to FALSE, the SRF initiates a bearer channel disconnect to the SSF and the SRSM-FSM moves to the state "Idle".
+- 4) Otherwise the SRSM-FSM moves to the state "User Interaction", or remains in the same state.
+
+The announcement send to the end-user is ended in the following conditions:
+
+- if neither "duration" or "numberOfRepetitions" is specified, then the network specific announcement ending conditions shall apply; or
+- if "numberOfRepetitions" is specified, when all repetitions have been sent; or
+- if duration is specified, when the duration has expired. The announcement is repeated until this condition is met; or
+- if "duration" and "numberOfRepetitions" is specified, when one of both conditions is satisfied (whatever comes first).
+
+The above conditions are overruled if the parameter "interruptableAnnInd" is not set to FALSE and the end-user has responded with a digit during the sending of the announcement. In this case the announcement is ended immediately. The above procedures apply only to inband information and tones send to the end-user, for "displayInformation" the end conditions are met upon sending, i.e. no interruption can occur.
+
+The parameter "errorTreatment" specifies how the SRF shall treat the error. The default value "reportErrorToSCF" means that the error shall be reported to SCF by means of Return Error with "ImproperCallerResponse". The value "help" indicates that no error shall be reported to SCF but assistance shall be given to the end-user in form of a network dependent default announcement (which may be dependent on the context, i.e. the send message). The value "repeatPrompt" indicates that no error shall be reported to the SCF but the prompt shall be repeated to the end-user. The last two procedures shall only be done once per "PromptAndCollectUserInfo" operation.
+
+NOTE – Processing "endOfInput": The receipt of any "endOfInput" condition (e.g. endOfReplyDigit, cancelDigit, firstDigitTimeout, interDigitTimeout) terminates immediately the ongoing input. In other words, when e.g. an endOfReplyDigit is received, the receipt of a subsequent cancelDigit will not be processed anymore.
+
+### **3.3.33.3.2 Error handling**
+
+If a Cancel operation is received before or during the processing of the operation, then the operation is immediately cancelled and the error "Cancelled" is reported to the invoking entity.
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+If any of the parameter restrictions are violated (e.g. minimumNbOfDigits > maximumNbOfDigits), then an operation error has occurred.
+
+### **3.3.34 ReleaseCall procedure**
+
+#### **3.3.34.1 General description**
+
+This operation is used to tear down by the SCF an existing call at any phase of the call for all parties involved in the call. This operation may not be sent to an assisting SSF, except in the case of hand-off procedure.
+
+##### **3.3.34.1.1 Parameters**
+
+- Cause:  
+A number giving an indication to the SSF about the reason of releasing this specific call. This may be used by SSF for generating specific tones to the different parties in the call or to fill in the 'cause' in the release message.
+
+#### **3.3.34.2 Invoking Entity (SCF)**
+
+##### **3.3.34.2.1 Normal procedure**

+
+#### **3.3.35 RemoveEntry procedure**
+
+##### **3.3.35.1 General description**
+
+The X.500 'RemoveEntry' operation is used to request the SDF to remove a leaf entry (either an object entry or an alias entry) from the DIT. For a full description of the RemoveEntry operation, see 11.2/X.511.
+
+##### **3.3.35.1.1 Parameters**
+
+See 11.2.2/X.511 and 11.2.3/X.511.
+
+##### **3.3.35.2 Invoking Entity (SCF)**
+
+##### **3.3.35.2.1 Normal procedure**
+
+SCF Precondition:
+
+- SCSM: "SDF Bound" or "Wait for Subsequent Requests".
+
+SCF Postcondition:
+
+- SCSM: "SDF Bound".
+
+When the SCSM is in the state "Wait for Subsequent Requests" and a need of the service logic to remove an entry from the SDF exists, an internal event [(e2) Request\_to\_SDF] occurs. Until the application process has not indicated with a delimiter (or a timer expiry) that the operation should be sent, the SCSM remains in the state "Wait for Subsequent Requests" and the operation is not sent. The operation is sent to the SDF in a message containing a Bind argument. The SCSM waits for the response from the SDF. The reception of the response [(E5) Response\_from\_SDF\_with\_Bind or (E4) Bind\_Error] to the Bind operation previously issued to the SDF causes a transition of the SCF to the state "SDF Bound" or to the state "Idle". When the SCSM has moved to state "Idle", the RemoveEntry operation was discarded. In the State "SDF Bound", the response of the RemoveEntry operation [(E7) Response\_from\_SDF] causes a transition of the SCF to the same state ("SDF Bound"). It may be either the result of the RemoveEntry operation or an error.
+
+When the SCSM is in the state "SDF Bound" and a need of the service logic to remove an entry from the SDF exists, an internal event occurs. This event, called (e6) Request\_to\_SDF causes a transition to the same state "SDF Bound" and the SCSM waits for the response from the SDF. The reception of the response [(E7) Response\_from\_SDF] to the RemoveEntry operation previously issued to the SDF causes a transition of the SCF to the same state "SDF Bound". The response from the SDF may be either the result of the RemoveEntry operation or an error.

+- SDSM: "SCF Bound" or "Bind Pending".
+
+SDF Postcondition:
+
+- SDSM "SCF Bound".
+
+When the SDF is in the state "Bind Pending", the external event (E3) Request\_from\_SCF caused by the reception of a 'RemoveEntry' operation from the SCF occurs. The SDF does not proceed to the operation until a Bind operation has been successfully executed. It remains in the same state.
+
+When the SDF is in the state "SCF Bound", the external event (E7) Request\_from\_SCF caused by the reception of a 'RemoveEntry' operation from the SCF occurs. The SDF waits for the response to the operation.
+
+On the receipt of the event (E7) and before removing the entry item, the SDF takes the following actions:
+
+- verify that the object to be removed exists and is a leaf entry;
+- verify that the access rights to remove the entry are sufficient.
+
+After the specified actions indicated above are successfully executed, the entry is removed from the SDF database. A null result is returned to the SCF. The sending of the result corresponds to the event (e6) Response\_to\_SCF.

+- 2) The SCME is in the state "Status Report Idle".
+
+SCF Postcondition:
+
+- The SCME is in the state "Waiting for SSF Response Status Report".
+
+When the SPLI requests to watch the status of physical termination resource, the SCF sends "Request Current Status Report" operation to the SSF to request the SSF watch the status of a specific termination resource. Then the SCME is moved to the state "Waiting for SSF Response Status Report" from the state "Status Report Idle".

+
+- The SCME is in the state "Waiting for SSF Response Status Report".
+
+When the SPLI requests to monitor the status of physical termination resource, the SCF sends "Request First Status Match Report" operation to the SSF to request the SSF start to monitor a specific termination resource. Then the SCME is moved to the state "Waiting for SSF Response Status Report" from the state "Status Report Idle". After this, in the case that the SCF receives ReturnResult of this operation, the SCME is remained in same status.

If an error is occurred (e.g. the SSF cannot find specific termination resource), then the SSF sends ReturnError of this operation with proper error type to the SCF.
+
+The SSF continuously monitors the status of particular termination resource till the status is changed in specific state or timer which is specified by monitorDuration parameter is expired. If the SSF finds the change of status in specific state, the SSF sends "Status Report" operation to the SCF with monitorCondition parameter set to "statusReport". If the timer expiration is occurred, the SSF sends "StatusReport" operation to the SCF with monitorCondition parameter is set to "timerExpired". Another case, the SSF receives "Cancel Status Report" operation from the SCF, the SSF sends "Status Report" operation to the SCF with monitorCondition parameter set to "Canceled". After the SSF sends this operation, the SSME should move to the state "IdleManagement" unless there are another processes of Non-Call Associated operation, in which case the SSF should remain in the "Non\_Call\_Associated\_Treatment".

+## 3.3.38 RequestNotificationChargingEvent procedure
+
+### 3.3.38.1 General description
+
+This operation is used to instruct the SSF how to manage the charging events which are received from other FE's not under the control of the service logic instance. The operation supports the options to cope with the interactions concerning the charging (refer to Appendix II.4/Q.1214 "Charging scenarios"). As several connection configurations may be established during a call, a possibility exists for the RequestNotificationChargingEvent (RNC) operation to be invoked on multiple occasions. For each connection configuration an RNC may be used several times.
+
+#### 3.3.38.1.1 Parameters
+
+- Sequence of ChargingEvent:
+
+This parameter contains a list of the charging events and the corresponding monitor types and corresponding legs. For each element in the list the following information elements are included:
+
+- eventTypeCharging:
+
+This subparameter indicates the charging event type. Its content is network operator specific, which may be "charge pulses" or "charge messages".
+
+- monitorMode:
+
+This subparameter indicates the monitorMode applicable for the corresponding "eventTypeCharging" subparameter. Monitor may be "interrupted", "notifyAndContinue" or "transparent".
+
+- legID:
+
+This subparameter indicates the leg id of the corresponding event type charging subparameter.
+
+#### 3.3.38.2 Invoking Entity (SCF)
+
+##### 3.3.38.2.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) A control relationship exists between the SCF and the SSF.
+- 2) An SLPI has determined that a "RequestNotificationChargingEvent" has to be sent by the SCF.
+
+SCF Postconditions:
+
+- 1) No FSM state transition;
+- 2) SLPI execution may continue.
+
+The SCSM-FSM is in state "Preparing SSF Instruction" or is in state "Queueing FSM". This operation is invoked by the SCF if a SLPI results in the instruction of SSF how to cope with the interactions concerning the charging. This causes no SCSM-FSM state transition.

+SSF-FSM State f: "Monitoring"; or  
+Assisting/Hand-off SSF-FSM State b: "Waiting for Instructions".
+
+SSF Postcondition:
+
+- No FSM state transition.
+
+On receipt of this operation the SSF performs actions to cope with the interactions concerning the charging according to the information elements included in the operation. The requested charging event can be caused by:
+
+- a) another SLPI; or
+- b) another exchange.
+
+Irrespective of by what the charging event is caused, the SSF performs one of the following actions on occurrence of the charging event (according the corresponding monitorMode):
+
+- **Interrupted:**  
+Notify the SCF of the charging event using "EventNotificationCharging" operation, do not process the event or propagate the signal. However, call and existing charging processing will not be suspended in the SSF.
+- **NotifyAndContinue:**  
+Notify the SCF of the charging event using "EventNotificationCharging", and continue processing the event or signal without waiting for SCF instructions (handled like EDP-N for BCSM events).
+- **Transparent:**  
+Do not notify the SCF of the event. This ends the monitoring of a previously requested charging event.
+
+Requested charging events are monitored until ended by a transparent monitor mode (or in the case of charging events) until the end of the connection configuration.
+
+In the case that multiple "RequestNotificationChargingEvent" operations are received for the same connection configuration with the same "eventTypeCharging" and "legID", only the last received "monitorMode" will apply.

+
+This operation is used to request the SSF to monitor for a call-related event (e.g. BCSM events such as busy or no answer), then send a notification back to the SCF when the event is detected.
+
+NOTE – If the RequestReportBCSMEVENT requests arming of the current DP from which the call processing was suspended, the next occurrence of the DP encountered during BCSM processing will be detected (i.e. not the current one from which the call was suspended).
+
+##### 3.3.39.1.1 Parameters
+
+- bcsmEvents:
+
+This parameter specifies the event or events of which a report is requested.
+
+- a) eventTypeBCSM:
+
+This parameter specifies the type of event of which a report is requested. Values origAttemptAuthorized and termAttemptAuthorized are not valid for the eventTypeBCSM parameter.
+
+b) monitorMode:
+
+This parameter indicates how the event should be reported. When the 'monitorMode' is 'interrupted', the event shall be reported as a request, if the 'monitorMode' is 'notifyAndContinue', the event shall be reported as a notification, if the 'monitorMode' is 'transparent', the event shall not be reported.
+
+c) legID:
+
+This parameter indicates the party in the call for which the event shall be reported. SCF will use the option 'sendingSideID' only.
+
+– sendingSideID:
+
+The following values for 'legID' are assumed:
+
+legID = 1 indicates the party that was present at the moment of the 'InitialDP' or a DP-specific operation (in case of a mid call trigger, the party causing the trigger), or the party that was created with an 'InitiateCallAttempt' operation.
+
+legID = 2 indicates the party that was created with a 'Connect' operation, or in case of a mid call trigger, the party not causing the trigger.
+
+If not included, the following defaults are assumed:
+
+legID = 1 for the events CollectedInfo, AnalysedInformation, O-Abandon and T-Abandon.
+
+legID = 2 for the events RouteSelectFailure, O-CalledPartyBusy, O-NoAnswer, O-Answer, T-Busy, T-NoAnswer and T-Answer.
+
+The 'legID' parameter shall always be included for the events O-MidCall, O-Disconnect, T-MidCall and T-Disconnect.
+
+d) dPSpecificCriteria:
+
+This parameter indicates information specific to the EDP to be armed.
+
+– numberOfDigits:

+
+### **3.3.42 Search procedure**
+
+#### **3.3.42.1 General description**
+
+The X.500 'Search' operation is used to search a portion of the SDF resident DIT for entries of interest and to return selected information from those entries. For a full description of the Search operation, see 10.2/X.511.
+
+##### **3.3.42.1.1 Parameters**
+
+See 10.2.2/X.511 and 10.2.3/X.511.
+
+#### **3.3.42.2 Invoking Entity (SCF)**
+
+##### **3.3.42.2.1 Normal procedure**
+
+SCF Precondition:
+
+- 1) SCSM: "SDF Bound" or "Wait for Subsequent Requests".
+
+SCF Postcondition:
+
+- SCSM: "SDF Bound".
+
+When the SCSM is in the state "Wait for Subsequent Requests" and a need of the service logic to search and/or read information of the SDF exists, an internal event [(e2) Request\_to\_SDF] occurs. Until the application process has not indicated with a delimiter that the operation should be sent, the SCSM remains in the state "Wait for Subsequent Requests" and the operation is not sent. The operation is sent to the SDF in a message containing a Bind argument. The SCSM waits for the response from the SDF. The reception of the response [(E5) Response\_from\_SDF\_with\_Bind or (E4) Bind\_Error] to the Bind operation previously issued to the SDF causes a transition of the SCF to the state "SDF Bound" or to the state "Idle". When the SCSM has moved to state "Idle", the Search operation was discarded. In the State "SDF Bound", the response of the Search operation [(E7) Response\_from\_SDF] causes a transition of the SCF to the same state ("SDF Bound"). It may be either the result of the Search operation or an error.
+
+When the SCSM is in the state "SDF Bound" and a need of the service logic to search and/or read information of the SDF exists, an internal event occurs. This event, called (e6) Request\_to\_SDF causes a transition to the same state "SDF Bound" and the SCSM waits for the response from the SDF. The reception of the response [(E7) Response\_from\_SDF] to the Search operation previously issued to the SDF causes a transition of the SCF to the same state "SDF Bound". The response from the SDF may be either the result of the Search operation or an error.
+
+##### **3.3.42.2.2 Error handling**
+
+Generic error handling for the operation related errors is described in 10.2.4/X.511 and 10.2.5/X.511 and the TCAP services that are used for reporting operating errors are described in 2.2.2.

+#### **3.3.42.3 Responding Entity (SDF)**
+
+##### **3.3.42.3.1 Normal procedure**
+
+SDF Precondition:
+
+- 1) SDSM: "SCF Bound" or "Bind Pending".
+
+SDF Postcondition:
+
+- SDSM "SCF Bound".
+
+When the SDF is in the state "Bind Pending", the external event (E3) Request\_from\_SCF caused by the reception of a 'Search' operation from the SCF occurs. The SDF does not proceed to the operation until a Bind operation has been successfully executed. It remains in the same state.
+
+When the SDF is in the state "SCF Bound", the external event (E7) Request\_from\_SCF caused by the reception of a 'Search' operation from the SCF occurs. The SDF waits for the response to the operation.
+
+On the receipt of the event (E7) and before retrieving the data as specified in the operation parameters, the SDF takes the following actions:
+
+- verify that the objects accessed by the request exists;
+- verify that the user on behalf of whom the request is performed has sufficient access rights to access the objects and attributes reached during the execution of the operation;
+- verify that attributes on which an operation should be performed exist in the object.
+
+After the specified actions indicated above are successfully executed, the SDF returns all the possible attributes that satisfy the retrieval criteria to the SCF. The sending of the result corresponds to the event (e6) Response\_to\_SCF.

+## 3.3.43 SelectFacility procedure
+
+### 3.3.43.1 General description
+
+This operation is sent by the SCF to the SSF and requests the SSF to perform the terminating basic call processing actions to select the terminating line if it is idle, or selects an idle line from a multi-line hunt group, or selects an idle trunk from a trunk group, as appropriate. If no idle line or trunk is available, the SSF determines that the terminating facility is busy. Refer to 4.2.2.2/Q.1214 for additional call modelling related semantics.
+
+#### 3.3.43.1.1 Parameters
+
+- alertingPattern:  
+See Recommendation Q.1290. It only applies if the network signalling supports this parameter or if SSF is the terminating local exchange for the subscriber.

+- SLPI execution may continue.
+
+In the SCSM-FSM state “Preparing SSF Instructions”, this operation is invoked by an SCF if the service logic results in the request to an SSF to route a call to a specific destination and to continue call processing at the Select\_Facility\_and\_Present\_Call PIC. If no event monitoring has been requested and no reports (CallInformationReport and ApplyChargingReport) have been requested in a previously sent operation, an SCSM-FSM transition to the state “Idle” occurs. Otherwise, if event monitoring has been requested or any report (CallInformationReport and ApplyChargingReport) has been requested, the SCSM-FSM transitions to the state “Waiting for Notification or Request”.
+
+#### **3.3.43.2.2 Error handling**
+
+If reject or error messages are received, then the SCSM informs the SLPI of the message and remains in the state “Preparing SSF Instructions”.

+
+##### **3.3.44.1 General description**
+
+This operation requests the SSF to perform the originating basic call processing actions to determine routing information and select routing for a call, based either on call information available at the SSF or on call information provided by the SCF. Based on the routing information provided, the SSF attempts to select a primary route for the call. If the route is busy, the SSF attempts to select an alternative route. The SSF may fail to select a route for the call if all routes are busy.
+
+##### **3.3.44.1.1 Parameters**
+
+- destinationRoutingAddress:  
+Represents a list of called party numbers (primary and alternates).
+- alertingPattern:  
+See Recommendation Q.1290. It only applies if the network signalling supports this parameter or if SSF is the terminating local exchange for the subscriber.
+- correlationID:  
+Used by the SCF to associate the 'AssistRequestInstructions' operation from the assisting SSF with the Request from the initiating SSF. The 'correlationID' is used in the context of a hand-off procedure and only if the correlation id is not embedded in the 'destinationRoutingAddress'.

+
+### 3.3.45 SendChargingInformation procedure
+
+#### 3.3.45.1 General description
+
+This operation is used to instruct the SSF on the charging information to be sent by the SSF. The sending of charging information can either be by charge pulses or signalling or internal if SSF is located in the Local Exchange (LE). In the LE, either charge meter can be updated or a standard call record created. A possibility exists for the SendChargingInformation (SCI) operation to be invoked on multiple occasions. The charging scenario supported by this operation is: 3.2 (refer to Appendix II/Q.1214, "Charging scenarios").
+
+NOTE – The interworking between SSF and PSTN is network operator specific. This operation has much PSTN/IN interactions.
+
+#### 3.3.45.1.1 Parameters
+
+- sCIBillingChargingCharacteristics:
+
+This parameter indicates billing and/or charging characteristics. Its content is network operator specific. Depending on the applied charging scenario, the following information elements can be included (refer to Appendix II/Q.1214, "Charging scenarios"):
+
+- charge level (scenario 3.2);
+- chargePulses;
+- chargeMessages.
+- partyToCharge:
+
+This parameter indicates where the charging information must be sent.
+
+#### 3.3.45.2 Invoking Entity (SCF)
+
+##### 3.3.45.2.1 Normal procedure
+
+SCF Preconditions:

+- 2) An SLPI has determined that a "SendChargingInformation" has to be sent by the SCF.
+
+SCF Postconditions:
+
+- 1) No FSM state transition;
+- 2) SLPI execution may continue.
+
+The SCSM-FSM is in state "Preparing SSF Instruction" or is in state "Queueing FSM". The SendChargingInformation procedure shall be invoked by the SCF in accordance with the demands of the SLPI for relevant charging information. If appropriate this information shall be sent back down the call path.
+
+This causes no SCSM-FSM state transition.

+
+SSF-FSM: State f: "Monitoring"; or  
+Assisting/hand-off SSF-FSM State b: "Waiting for Instructions".
+
+SSF Postcondition:
+
+- No FSM state transition.
+
+On receipt of this operation the SSF performs actions to send the charging information. The sending of charging information can either be by charge pulses or signalling or internal if SSF is located in LE. In the LE, either charge metre can be updated or a standard call record created. The interworking between SSF and PSTN is network operator specific. This operation has much PSTN/IN interactions.
+
+For instance, by sending an operation "SendChargingInformation" the SCF instructs the SSF to initiate the PSTN/ISDN charging functions according to the given information about the charging level to use.
+
+The charging level can be determined either by one of the following functions:
+
+- a) the SCF; or
+- b) the SSF; or
+- c) the charging function in a succeeding exchange.
+
+In case the SCF has determined the charging level, the "SendChargingInformation" operation contains the charging level to be applied.
+
+In case the SSF determines the charging level, the "SendChargingInformation" operation contains the parameters to determine the charging level.
+
+If the charging level was determined by the IN (SCF or SSF), the SSF provides the charging level to be applied to the PSTN/ISDN charging functions [cases a) and b)].
+
+In case c), the charging level is determined in a succeeding exchange. The "SendChargingInformation" operation either contains the corresponding parameters indicating this fact or the SSF detects during trying to determine the charging level based on SCF provided parameters that the charging level shall be determined in a succeeding exchange. Based on already existing PSTN/ISDN capabilities, the SSF provides the PSTN/ISDN charging functions with the necessary information and backward charge messages shall be transferred down the call path when allowed by the SCF (generated by a succeeding exchange, for example an international gateway).
+
+In the scenario described above, charging/billing is performed by means of existing mechanisms of the PSTN/ISDN initiated and controlled by the IN.
+
+That means the determination of the charging method – on-line or off-line – and the items to be charged for shall be done in the basic network, just like the charge generation and the charge registration.

+
+### **3.3.46 ServiceFilteringResponse procedure**
+
+#### **3.3.46.1 General description**
+
+This operation is used to report the values of counters specified in a previous sent 'ActivateServiceFiltering' operation to the SCF.
+
+##### **3.3.46.1.1 Parameters**
+
+- countersValue:
+
+The parameter contains the count of calls filtered during the filtering period. It is a list of counter identifications and the related values.
+
+- filteringCriteria:
+
+This parameter is used to address the concerned service logic at the SCF.
+
+- responseCondition:
+
+This parameter is used to identify the reason why the ServiceFilteringResponse is sent.
+
+intermediateResponse indicates that service filtering is active, a call is received and the interval timer is expired; or
+
+that service filtering is active and the threshold value, 'numberOfCalls', is reached.
+
+lastResponse indicates that the duration time is expired and service filtering is stopped, or that the stop time is met and service filtering is stopped.
+
+### 3.3.46.2 Invoking Entity (SSF)
+
+#### 3.3.46.2.1 Normal procedure
+
+SSF Preconditions:
+
+- 1) Service filtering is running and the interval time is expired and a call is received; or
+- 2) Service filtering is running and the threshold value is reached; or
+- 3) Service filtering has been finished (duration time expired or stop time met); or
+- 4) The operation 'ActivateServiceFiltering' is received and encounters an active service filtering entity.
+
+SSF Postcondition:
+
+- Service filtering proceeds or is ended depending on the duration time.
+
+The SSF sends the 'ServiceFilteringResponse' operation to the SCF. The 'filteringCriteria' parameter is provided to enable the addressing of the concerned service logic at the SCF.
+
+Before 'ServiceFilteringResponse' is sent, it is checked whether call gapping criteria are met. If so, the 'ServiceFilteringResponse' is not sent and the counting continues without resetting the counters. The last 'ServiceFilteringResponse' (stop time is met or duration time expired) is sent without checking any call gap criteria.
+
+After sending 'ServiceFilteringResponse' the service filtering counters are reset.
+
+If service filtering proceeds after sending 'ServiceFilteringResponse' (e.g. interval time expired), the SSME-FSM remains in the state "Non\_Call\_Associated\_Treatment".
+
+If service filtering is stopped after sending 'ServiceFilteringResponse' (duration time expired or stop time is met), then the SSME-FSM moves to the "Idle Management" state. All allocated resources are released, i.e. the SSME-FSM is removed as well.

+
+The "filteringCriteria" parameter as provided in "ServiceFilteringResponse" is used to address the SCME and the concerned service logic instance.
+
+The Service Filtering FSM of the SCME remains in the state "Waiting For SSF Service Filtering Response" until the internal service filtering duration time in the SLPI expires. Then the SLPI informs the SCME about timer expiration. Now the SCME moves to the state "Service Filtering Idle".

+#### 3.3.52.3.1 Normal procedure
+
+SCF Preconditions:
+
+- 1) For TDP, none.
+- 2) EDP case does not apply.
+
+SCF Postconditions:
+
+- 1) An SLPI has been invoked.
+- 2) For a TDP-R, an SSF instruction is being prepared.
+
+On receipt of the TermAttemptAuthorized operation, the SCSM moves from "Idle" state to the state "Preparing SSF Instructions". A control relationship to the related SSF is created. A Service Logic Program Instance (SLPI) is invoked for processing the TermAttemptAuthorized operation. By means of this control relationship, the SCF may influence the Basic Call Processing in accordance with the service logic invoked. The actions to be performed in the SLPI depend on the parameters conveyed via this operation and the SLPI (i.e. the requested IN service itself).
+
+### **3.3.52.3.2 Error handling**
+
+If the TermAttemptAuthorized operation is rejected, then the SCSM remains in the same state. The maintenance function is informed and no SLPI is invoked. Generic error handling for the operation related errors is described in 3.2 and the TCAP services which are used for reporting operation errors are described in 3.4.
+
+### **3.3.53 TNoAnswer procedure**
+
+#### **3.3.53.1 General description**
+
+This operation is sent from the SSF to the SCF after detecting a valid trigger condition at the T\_No\_Answer DP, or to report an event requested by RequestReportBCSMEvent.
+
+This operation requests the SSF-CCF to send a T\_No\_Answer TDP-Request message when it encounters a T\_No\_Answer trigger.

+
+#### 3.3.54 Unbind procedure
+
+##### 3.3.54.1 General description
+
+The X.500 'Unbind' operation is used by the SDF to end an authenticated association between an SCF and an SDF on behalf of the end user. For a full description of the Unbind operation, see 8.2/X.511.
+
+##### 3.3.54.1.1 Parameters
+
+None.
+
+### **3.3.54.2 Invoking Entity (SCF)**
+
+#### **3.3.54.2.1 Normal procedure**
+
+SCF Preconditions:
+
+- SCSM: "SDF Bound".
+
+SCF Postconditions:
+
+- SCSM: "Idle".
+
+The SCSM has previously initiated a successful Bind operation to the SDF directory. It is in state "SDF Bound". The service logic determines that the authenticated access to the SDF is to be terminated. It issues an Unbind operation [(e8) Unbind\_request] that causes the SCSM to transit back to the state "Idle".
+
+#### **3.3.54.2.2 Error handling**
+
+The 'Unbind' operation does not have operation related errors.
+
+### **3.3.54.3 Responding Entity (SDF)**
+
+#### **3.3.54.3.1 Normal procedure**
+
+SDF Preconditions:
+
+- SDSM: "SCF Bound".
+
+SDF Postconditions:
+
+- SDSM: "Idle".
+
+A Bind operation was previously issued and the SDSM is in State "SCF Bound" waiting for a request from the SCF and/or performing an operation. The reception of the Unbind operation causes a transition to State "Idle" with the transition (E5) Unbind\_from\_SCF.
+
+#### **3.3.54.3.2 Error handling**
+
+The 'Unbind' operation does not have operation related errors.
+
+### **3.3.55 RequestEveryStatusChangeReport procedure**
+
+#### **3.3.55.1 General description**
+
+This operation is used to request the SSF start to monitor every change of the busy/idle status of a particular termination.
+
+##### **3.3.55.1.1 Parameters**
+
+- resourceID:
+
+This parameter indicates that physical termination resource which is requested by the SCF to be monitored by the SSF. This parameter is one of the lineID, facilityGroupID, facilityGroupMemberID, or trunkGroupID.
+
+- correlationID:
+
+This parameter is used by the SCF to associate the "StatusReport" from the SSF with the request in the SCF.
+
+- monitorDuration:
+
+This parameter indicates the maximum time duration for monitoring in the SSF.
+
+### **3.3.55.2 Invoking Entity (SCF)**
+
+#### **3.3.55.2.1 Normal procedure**
+
+SCF Preconditions:
+
+- 1) The SLPI has been determined that a "Request Every Status Change Report" operation has to be sent.
+- 2) The SCME is in the state "Status Report Idle".
+
+SCF Postcondition:
+
+- The SCME is in the state "Waiting for SSF Response Status Report".
+
+When the SPLI requests to monitor every change of the busy/idle status of a physical termination resource, the SCF sends "Request Every Status Change Report" operation to the SSF to monitor every change of the status of a particular termination resource. Then the SCME is moved to the state "Waiting for SSF Resource Status Report" from the state "Status Report Idle". After this, in the case that the SCF receives ReturnResult of this operation, the SCME remains in same state. When the SCF receives ReturnError of this operation, the SCME is returned to the state "Status Report Idle".
+
+When the SCF receives a Status Report operation from the SSF, the SCME remains in the state "Waiting for SSF Resource Status Report". Alternatively when the SCF receives a "Status Report" operation with the monitorCondition parameter set to "timerExpired" or "cancelled" from SSF, the SCME is returned to the state "Status Report Idle".
+
+Clarification on the use of this operation within or outside the context of a call is for further study.
+
+### 3.3.55.2.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services used for reporting operation errors are described in 3.4.
+
+### 3.3.55.3 Responding Entity (SSF)
+
+#### 3.3.55.3.1 Normal procedure
+
+SSF Precondition:
+
+- The SSME is in one of the following states:  
+state ma: "IdleManagement";  
+state mb: "Non-Call Associated Treatment".
+
+SSF Postcondition:
+
+- The SSME is in one of the following states:  
+state ma: "IdleManagement";  
+state mb: "Non-Call Associated Treatment".
+
+On receipt of this operation, the SSF starts to monitor every change of the busy/idle status of a particular termination resource. If an error is occurred (e.g. the SSF can not find the specific termination resource), then the SSF sends ReturnError of this operation with proper error type to the SCF.
+
+The SSF continuously monitors every change of the busy/idle status of a particular termination resource until a timer which is specified by monitorDuration parameter expires. Whenever the SSF finds a change of status, the SSF sends the "Status Report" Operation to the SCF with monitorCondition parameter set to "statusReport". After sending this operation, the SSF should remain in the "Non-Call Associated Treatment" state. If timer expiration occurs, the SSF sends the "StatusReport" Operation to the SCF with monitorCondition parameter set to "timerExpired". Alternatively, when the SSF receives a "Cancel Status Report" operation from the SCF, the SSF sends the "Status Report" Operation to the SCF with monitorCondition parameter set to "Cancelled". After the SSF sends this operation, the SSME should move to the state "IdleManagement" unless there are other processes of Non-Call Associated operation, in which case the SSF should remain in the state "Non-Call AssociatedTreatment".
+
+#### 3.3.55.3.2 Error handling
+
+Generic error handling for the operation related errors is described in 3.2 and the TCAP services used for reporting operation errors are described in 3.4.
+
+## 3.4 Services assumed from TCAP
+
+This subclause describes the procedures and TCAP primitives that shall be used for transmitting messages between SSF, SCF and SRF. For the SCF-SDF interface, refer to 2.2.2.2.
+
+### 3.4.1 Normal procedures
+
+This subclause describes the procedures and TCAP primitives that shall be used for transmitting messages between SSF, SCF and SRF under normal operation.
+
+The INAP, as TC-user, uses only the structured dialogue facility provided by TCAP. The following situations can occur when a message is sent between two physical entities:
+
+- a) A dialogue shall be established – The TC-user issues a TC-BEGIN request primitive.
+- b) A dialogue shall be maintained – The TC-user issues a TC-CONTINUE request primitive.
+- c) A dialogue shall no longer be maintained – The TC-user issues a TC-END request primitive with either basic end or with pre-arranged end depending on the following conditions:
+  - i) Basic End
+    - In the case the dialogue is established, operations, leading to a termination of the relationship, can be transmitted by the FE with a TC-END request primitive (basic) in case the FE is not interested in the reception of any ERROR or REJECT components for these sent operations. Once the FE dialogue resources have been released, any ERROR or REJECT components received for these operations will be discarded by TC as described in Recommendation Q.774.
+    - In the case the dialogue is established and the FE has received an operation, leading to the termination of the relationship does not interest to continue dialogue and there is no operation to be sent, a TC-END request primitive (basic) with zero components can be sent from the FE.
+  - ii) Pre-arranged End:
+    - In the case, an entity is interested in possible ERROR or REJECT messages on response to sent operations leading to a termination of the relationship, the dialogue is ended with a TC-END request primitive (pre-arranged end) after the last associated operation timer expires. The receiving entity can end the dialogue with a TC-END request primitive (pre-arranged end) after successful processing of these operations (i.e. the relationship is terminated).
+- d) In general, the use of pre-arranged end shall be limited to the case for both communicating entities clearly recognizable that peer entity applies pre-arranged end. In all other cases, basic end shall be used.
+- e) A dialogue shall not be established – For class 2 or 4 operations only the sending TC-user issues a TC-BEGIN request primitive and ends the dialogue locally after operation time out by means of a pre-arranged end. Upon reception of the TC-BEGIN indication primitive the receiving TC-user shall end the dialogue locally.
+
+#### 3.4.1.1 SSF-to-SCF messages
+
+##### 3.4.1.1.1 SSF-FSM related messages
+
+A dialogue shall be established when the SSF-FSM moves from the state **Idle** to the state **Waiting for Instructions**. The relevant INAP operation, which can be the InitialDP operation or one of DP specific operations for TDP-R, shall be transmitted in the same message.
+
+No dialogue shall be established when the SSF-FSM moves from the state **Idle** and back to the state **Idle** on the detection of TDP-N. The relevant INAP operation, which can be the InitialDP operation or one of DP specific operations for TDP-N, shall be sent with a TC-BEGIN request primitive and the dialogue is locally ended by means of TC-END request primitive with pre-arranged end.
+
+For all other operations sent from the SSF-FSM, the dialogue shall be maintained except for the following cases.
+
+When the SSF-FSM makes a non-error case state transition to the state **Idle** and there is one or more pending operation and TCAP dialogue is established, TCAP dialogue can be terminated by TC-END primitive with component(s). When the SSF sends the last EventReportBCSM, ApplyChargingReport or CallInformationReport, the dialogue may be ended from the SSF by a TC-END request primitive with basic end.
+
+In the case that there is no pending operation and TCAP dialogue is established, TCAP dialogue can be terminated by TC-END primitive with zero component or pre-arranged end. When the SSF-FSM makes a non-error case state transition to the state **Idle** and there is no operation to be sent, the dialogue is ended by means of a TC-END request primitive (basic) with zero components, or the dialogue is locally ended by means of a TC-END request primitive with pre-arranged end.
+
+The SSF can end a dialogue with a TC-END request primitive with zero component or pre-arranged end depending on that TCAP dialogue is established or not, in the case call release is initiated by any other entity, then the SCF and the SSF has no pending call information requests (or pending requests which should be treated in the same way, see Note 1 of 3.1.1.5) nor any armed EDP to notify the SCF of the call release (for alternative way, see 3.4.2.2).
+
+When the SSF has sent the last EventReportBCSM, ApplyChargingReport or CallInformationReport, the dialogue may be ended from the SCF by a TC-END request primitive with basic end.
+
+#### 3.4.1.1.2 Assisting/Handoff SSF-FSM related messages
+
+A dialogue shall be established when the Assisting/Handoff SSF-FSM moves from the state **Idle** to the state **Waiting for Instructions**. The AssistRequestInstructions operation shall be transmitted with a TC-BEGIN request primitive.
+
+For all other operations sent from the Assisting/Handoff SSF-FSM, the dialogue shall be maintained except for the following cases.
+
+When the SSF-FSM makes a non-error case state transition to the state **Idle** and there is one or more pending operation and TCAP dialogue is established, TCAP dialogue can be terminated by TC-END primitive with component(s). When the SSF sends the last ApplyChargingReport, the dialogue may be ended from the SSF by a TC-END request primitive with basic end.
+
+In the case that there is no pending operation and TCAP dialogue is established, TCAP dialogue can be terminated by TC-END primitive with zero component or pre-arranged end. When the SSF-FSM makes a non-error case state transition to the state **Idle** and there is no operation to be sent, the dialogue is ended by means of a TC-END request primitive (basic) with zero components, or the dialogue is locally ended by means of a TC-END request primitive with pre-arranged end.
+
+When the SSF has sent the last ApplyChargingReport, the dialogue may be ended from the SCF by a TC-END request primitive with basic end.
+
+#### 3.4.1.1.3 SSME-FSM related messages
+
+The following procedures shall be followed:
+
+- The dialogue shall be maintained when the ActivityTest Return Result is sent.
+- No dialogue shall be established when the ServiceFilteringResponse operation is sent. The operation is sent with a TC-BEGIN request primitive and the dialogue is ended by means of a TC-END request primitive with pre-arranged end.
+- A dialogue shall no longer be maintained when the Return Result of the ActivateServiceFiltering operation is sent. The dialogue is ended by means of a TC-END request primitive with basic end, the Return Result is transmitted with the same request.
+- The dialogue is locally terminated by means of a TC-END request primitive with pre-arranged end, upon reception of a TC-BEGIN indication primitive with a CallGap operation.
+- The dialogue shall be maintained when the RequestCurrentStatusReport, RequestEveryStatusChangeReport or RequestFirstStatusMatchReport operation is received inside the call context.
+
+- The dialogue shall be maintained on sending following operations inside the call context if the operations are not final one:
+  - Return Result of the RequestCurrentStatusReport operation;
+  - Return Result of the RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation; and
+  - StatusReport operation in reply to RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation.
+- The dialogue shall no longer be maintained on sending following operations inside the call context if the operations are final one:
+  - Return Result of the RequestCurrentStatusReport operation;
+  - Return Result of the RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation; and
+  - StatusReport operation in reply to RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation.
+
+The dialogue is ended from the SSF by means of TC-END request primitive with basic end, one of the above operations is transmitted with the same request.
+
+If monitor duration expires for RequestFirstStatusMatchReport or RequestEveryStatusChangeReport which has been received inside the call context and there is no need to maintain dialogue, the dialogue is ended from the SSF by means of a TC-END request primitive (basic) with zero component.
+
+- The dialogue shall be established when the RequestCurrentStatusReport, RequestEveryStatusChangeReport or RequestFirstStatusMatchReport operation is received outside the call context.
+- The dialogue shall no longer be maintained when the Return Result of the RequestCurrentStatusReport operation is sent outside the call context. The dialogue is ended from the SSF by means of a TC-END request primitive with basic end, the Return Result is transmitted with the same request.
+- The dialogue shall be maintained when the Return Result of the RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation is sent outside the call context.
+- The dialogue shall no longer be maintained when the StatusReport operation is sent in reply to the RequestFirstStatusMatchReport operation outside the call context. The dialogue is ended from the SSF by means of a TC-END request primitive with basic end, the StatusReport operation is transmitted with the same request.
+- The dialogue shall be maintained when the StatusReport operation is sent in reply to the RequestEveryStatusChangeReport operation outside the call context.
+- The dialogue shall no longer be maintained when the monitor duration expires for RequestFirstStatusMatchReport or RequestEveryStatusChangeReport which has been received outside the call context. The dialogue is ended from the SSF by means of a TC-END request primitive (basic) with zero component.
+
+### 3.4.1.2 SCF-to-SSF messages
+
+#### 3.4.1.2.1 SCSM-FSM related messages
+
+No dialogue shall be established when the SCSM-FSM moves from state **Idle** to state **Idle** upon receipt of InitialDP operation or one of DP specific operations for TDP-N. The operation is received with a TC-BEGIN indication primitive and the dialogue is locally terminated by means of a TC-END request primitive with pre-arranged end.
+
+A dialogue shall be established when the SCSM-FSM moves from state **Idle** to state **Preparing SSF Instructions** upon the receipt of InitialDP operation for TDP-R, one of DP specific operations for TDP-R or AssistRequestInstructions operation.
+
+A dialogue shall be established when the SCSM-FSM moves from state **Idle** to state **Preparing SSF Instructions** on sending an InitiateCallAttempt operation to the SSF.
+
+For subsequent operations sent from the SCSM-FSM, the dialogue shall be maintained except for the following cases, i.e. all other operations are sent after a dialogue was established from the SSF (the SCF has previously received a TC-BEGIN indication primitive with an InitialDP operation, one of DP specific operations or an AssistRequestInstructions operation).
+
+The dialogue shall no longer be maintained when the pre-arranged end condition is met in the SCF. When the SCF does not expect any messages other than possibly REJECT or ERROR messages for the operations sent and when the last associated operation timer expires, the dialogue is locally ended by means of a TC-END request primitive with pre-arranged end. Alternatively, the sending of operations, leading to the termination of the relationship, by means of a TC-END request primitive (basic end) is possible.
+
+#### 3.4.1.2.2 SCME-FSM related messages
+
+The operations sent from the SCME-FSM shall be issued according to the following procedures:
+
+- The dialogue shall be maintained when the ActivityTest operation is sent.
+- A dialogue shall not be established when a CallGap operation is sent without using a SCSM associated dialogue. The operation is sent using a TC-BEGIN request primitive and the dialogue is terminated with a pre-arranged end.
+- For sending one or more CallGap operations, the SCME-FSM may use an existing SCSM-FSM associated dialogue which was initiated by a SSF-FSM (i.e. established for the transmission of the InitialDP operation or one of DP specific operations). The dialogue shall be maintained and the CallGap operation(s) shall be sent with the first response of the SCSM-FSM to the InitialDP operation or one of DP specific operations.
+- A dialogue shall be established when an ActivateServiceFiltering operation is sent. The operation shall be transmitted with a TC-BEGIN request primitive.
+- The dialogue is locally terminated upon reception of a ServiceFilteringResponse operation using a TC-END request primitive with pre-arranged end.
+- The dialogue shall be maintained when the RequestCurrentStatusReport, RequestEveryStatusChangeReport or RequestFirstStatusMatchReport operation is sent inside the call context.
+- The dialogue shall be maintained on receiving following operations inside the call context if the operations are not the final ones:
+  - Return Result of the RequestCurrentStatusReport operation;
+  - Return Result of the RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation; and
+  - StatusReport operation in reply to RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation.
+- The dialogue shall no longer be maintained on receiving following operations inside the call context if the operations are the final ones:
+  - Return Result of the RequestCurrentStatusReport operation;
+  - Return Result of the RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation; and
+  - StatusReport operation in reply to RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation.
+
+The dialogue is ended from the SSF by means of TC-END indication primitive with basic end, one of above operations is transmitted with the same request.
+
+If monitor duration expires for RequestFirstStatusMatchReport or RequestEveryStatusChangeReport which has been received inside the call context and there is no needs to maintain dialogue, the dialogue is ended from the SSF by means of a TC-END indication primitive (basic) with zero component.
+
+- The dialogue shall be established when the RequestCurrentStatusReport, RequestEveryStatusChangeReport or RequestFirstStatusMatchReport operation is sent outside the call context.
+- The dialogue shall no longer be maintained when the Return Result of the RequestCurrentStatusReport operation is received outside the call context. The dialogue is ended from the SSF by means of a TC-END indication primitive with basic end, the Return Result is transmitted with the same indication.
+- The dialogue shall be maintained when the Return Result of the RequestFirstStatusMatchReport or RequestEveryStatusChangeReport operation is received outside the call context.
+- The dialogue shall no longer be maintained when the StatusReport operation is received in reply to the RequestFirstStatusMatchReport operation outside the call context. The dialogue is ended from the SSF by means of a TC-END indication primitive with basic end, the StatusReport operation is received with the same indication.
+- The dialogue shall be maintained when the StatusReport operation is received in reply to the RequestEveryStatusChangeReport operation outside the call context.
+- The dialogue shall no longer be maintained when the monitor duration expires for RequestFirstStatusMatchReport or RequestEveryStatusChangeReport outside the call context. The dialogue is ended from the SSF by means of a TC-END indication primitive (basic) with zero component.
+
+### 3.4.1.3 SCF-to/from-SRF messages
+
+A dialogue is established when the SRF sends an AssistRequestInstructions operation to the SCF. For all other operations sent to/from the SRF, the dialogue shall be maintained.
+
+In the case that there is no pending operation and TCAP dialogue is established, TCAP dialogue can be terminated by TC-END primitive with zero component. When the SCSM makes a non-error case state transition to end user interaction and there is no operation to be sent, the dialogue is ended by means of a TC-END request primitive (basic) with zero components.
+
+The dialogue shall no longer be maintained when sending the SRReport operation for PlayAnnouncement with disconnection from the SRF set to TRUE or Return Result of the PromptAndCollectUserInfo with disconnection from the SRF set to TRUE. The dialogue is ended by means of a TC-END request primitive with basic end, and one of the above operations is transmitted with the same request.
+
+Regardless of whether pending operation exists or not, when the SRSM-FSM is informed of the disconnection of bearer connection (in the case of SCF initiated disconnection or call abandon from call party) and dialogue is established, the dialogue is ended by means of a TC-END request primitive (basic) with zero components or TC-END request primitive (pre-arranged end).
+
+The dialogue shall no longer be maintained when the pre-arranged end condition is met in the SRF. When the SRSM-FSM is informed the disconnection of bearer connection and TCAP dialogue is not established, TCAP dialogue is locally terminated by TC-END primitive with pre-arranged end.
+
+When the SCF does not expect any messages other than possibly REJECT or ERROR messages for the operations sent and when the last associated operation timer expires, the dialogue is locally ended by means of a TC-END request primitive with pre-arranged end. Alternatively, the sending of operations, leading to the termination of the relationship, by means of a TC-END request primitive (basic end) is possible.
+
+In the relay case, the SRF-SCF relationship uses the SSF-SCF TCAP dialogue. This is possible, because begin and end of the SRF-SCF relationship are embedded in the SSF-SCF relationship. SRF-SCF information shall be exchanged with TC-CONTINUE request primitives.
+
+In the case of the SSF relay, it is for further study how to map messages to ROSE capability of bearer signalling system between the SSF and the SRF, and what services are assumed from ROSE.
+
+### 3.4.2 Abnormal procedures
+
+This subclause describes the procedures and TCAP primitives that shall be used for reporting abnormal situations between SSF, SCF and SRF. The error cases are defined in 3.2.
+
+The following primitives shall be used to report abnormal situations:
+
+- operation errors, as defined in the INAP, are reported with TC-U-ERROR request primitive;
+- rejection of a TCAP component by the TC-user shall be reported with TC-U-REJECT request primitive;
+- when the FE detecting error or rejecting operation decides the termination of TC dialogue, TC-END request primitive (basic) with error or reject can be used for the termination of TC dialogue;
+- when the SSF or the SRF detecting error or rejecting operation recognizes the possibility to continue dialogue, TC-CONTINUE request primitive with error or reject can be used for the continuation of TC dialogue;
+- a dialogue shall be aborted by the TC-user with a TC-U-ABORT request primitive;
+- on expiration of application timer  $T_{\text{SSF}}$  or  $T_{\text{SRF}}$ , dialogue shall be terminated by means of a TC-U-ABORT primitive with an Abort reason, regardless of TCAP dialogue is established or not.
+
+For abnormal situations detected by TCAP the same rules shall apply for reception of TC-R-REJECT indication as for transmission of TC-U-REJECT request and for transmission of TC-P-ABORT indication as for transmission of TC-U-ABORT request primitive.
+
+The following rules shall be applied to terminate the TCAP dialogue under abnormal situations:
+
+- in the case that abort condition is detected and TCAP dialogue is established, TCAP dialogue is terminated by TC-U-ABORT primitive with an Abort reason;
+- in the case that abort condition is detected and TCAP dialogue is not established, TCAP dialogue is locally terminated by TC-U-ABORT primitive (in the case such as application time out).
+
+In error situations pre-arranged end shall not be used to terminate the TCAP dialogue. In case any application entity encounters an error situation, the peer entity shall be explicitly notified of the error, if possible. If from any entity's point of view the error encountered requires the relationship to be ended, it shall close the dialogue via a TC-END request primitive with basic end or via a TC-U-ABORT request primitive, depending on whether any pending ERROR or REJECT component is to be sent or not.
+
+In case an entity receives a TC-END indication primitive and after all components have been considered, the FSM is not in a state to terminate the relationship, an appropriate internal error should be provided.
+
+In cases when a dialogue needs to be closed by the initiating entity before its establishment has been completed (before the first TC indication primitive to the TC-BEGIN request primitive has been received from the responding entity), the TC-user shall issue a TC-END request primitive with pre-arranged end or a TC-U-ABORT request primitive. The result of these primitives will be only local, any subsequent TC indication received for this dialogue will be handled according to the abnormal procedures as specified in Recommendation Q.774.
+
+### 3.4.2.1 SCF-to-SSF/SRF messages
+
+Considering that both SSF and SRF do not have the logic to recover from error cases detected on the SCF-SSF/SRF interface, the following shall apply:
+
+- Operation errors and rejection of TCAP components shall be transmitted to the SSF and, respectively, the SRF with a TC-END request primitive, basic end.
+
+If, in violation of the above procedure, an ERROR or REJECT component is received with a TC-CONTINUE indication primitive, the SSF and, respectively, the SRF shall abort the dialogue with a TC-U-ABORT request primitive.
+
+In the case of the SSF relay, it is for further study how to map messages to ROSE capability of bearer signalling system between the SSF and the SRF, and what services are assumed from ROSE.
+
+### 3.4.2.2 SSF/SRF-to-SCF messages
+
+Operation errors and rejection of TCAP components shall be transmitted to the SCF according to the following rules:
+
+- The dialogue shall be maintained when the preceding message, which contained the erroneous component, indicated that the dialogue shall be maintained, i.e. the error or reject shall be transmitted with a TC-CONTINUE request primitive if the erroneous component was received with a TC-CONTINUE indication primitive.
+- On receipt of an ERROR or REJECT component the SCF decides on further processing. It may either continue, explicitly end or abort the dialogue.
+- In all other situations the dialogue shall no longer be maintained, i.e. the error or reject shall be transmitted with a TC-END request primitive, basic end, if the erroneous component was received with a TC-BEGIN indication primitive.
+- On expiration of application timer  $T_{\text{SSF}}$  or  $T_{\text{SRF}}$ , dialogue shall be terminated by means of a TC-U-ABORT primitive with an Abort reason, regardless of whether TCAP dialogue is established or not.
+
+If the error processing in the SSF-SRF leads to the case where the SSF-SRF is not able to process further SCF operations while the dialogue is to be maintained, the SSF-SRF aborts the dialogue with a TC-END request primitive with basic end or a TC-U-ABORT request primitive, depending on whether any pending ERROR or REJECT component is to be sent or not.
+
+The SSF can end a dialogue with a TC-U-ABORT request primitive in case call release is initiated by any other entity, then the SCF and the SSF has no pending call information requests (or pending requests which should be treated in the same way, i.e. ApplyCharging nor any armed EDP to notify the SCF of the call release (for alternative way, see 3.4.1.1.1)).
+
+In the case of the SSF relay, it is for further study how to map messages to ROSE capability of bearer signalling system between the SSF and the SRF, and what services are assumed from ROSE.
+
+### 3.4.3 Dialogue establishment
+
+The establishment of an INAP dialogue involves two application processes as described in 0.4, one that is the dialogue-initiator and one that is the dialogue-responder.
+
+Application context negotiation may not be supported in all physical entities and/or all networks.
+
+This procedure is driven by the following signals:
+
+- A TC-BEGIN request primitive from the dialogue-initiator.
+- A TC-BEGIN indication primitive occurring at the responding side.
+- The first TC-CONTINUE indication primitive occurring at the initiating side or under specific conditions:
+  - A TC-END indication primitive occurring at the initiating side.
+  - A TC-U-ABORT indication primitive occurring at the initiating side.
+  - A TC-P-ABORT indication primitive occurring at the initiating side.
+
+#### 3.4.3.1 Sending of a TC-BEGIN request primitive
+
+Before issuing a TC-BEGIN request primitive, SACF shall store the AC-name and if present the user-information parameter.
+
+SACF shall request the invocation of the associated operations using the TC-INVOKE service. See 3.4.8 for a description of the invocation procedure.
+
+After processing of the last invocation request, SACF shall issue a TC-BEGIN request primitive.
+
+The initiator SACF then waits for a TC indication primitive and will not issue any other requests, except a TC-U-ABORT request or a TC-END request with the release method parameter set to "pre-arranged release".
+
+If no TC indication primitive is expected because no dialogue is to be established according to the rules as stated in 3.4.1 and 3.4.2, SACF will wait for the last associated TCAP operation timer to expire and issue a TC-END request with the release method parameter set to "pre-arranged release".
+
+### **3.4.3.2 Receipt of a TC-BEGIN indication**
+
+On receipt of a TC-BEGIN indication primitive, responder SACF shall:
+
+- Analyse the application-context-name if included in the primitive. If it is supported, process any other indication primitives received from TC as described in 3.4.8.
+- If no dialogue is to be established according to the rules as stated in 3.4.1 and 3.4.2, SACF will wait for the last indication primitive from TC and issue a TC-END request with the release method parameter set to "pre-arranged release".
+- If the application-context-name included in the primitive is not supported, issue a TC-U-ABORT request primitive. If an alternative application-context can be offered its name is included in the TC-U-ABORT request primitive.
+
+It is for further study whether or not the application-context-negotiation is limited only for using the TC-U ABORT primitive.
+
+### **3.4.3.3 Receipt of the first TC-CONTINUE ind**
+
+On receipt of the first TC-CONTINUE indication primitive for a dialogue, SACF shall check the value of the application-context-name parameter. If this value matches the one used in the TC-BEGIN request primitive, SACF shall process the following TC component handling indication primitives as described in 3.4.8, otherwise it shall issue a TC-U-ABORT request primitive.
+
+It is for further study whether or not the application-context-negotiation is limited only for using the TC-U ABORT primitive.
+
+### **3.4.3.4 Receipt of a TC-END ind**
+
+On receipt of a TC-END indication primitive in the dialogue initiated state, SACF shall check the value of the application-context-name parameter. If this value matches the one used in the TC-BEGIN request primitive, then the SACF shall process the following TC component handling indication primitives as described in 3.4.8.
+
+### **3.4.3.5 Receipt of a TC-U-ABORT ind**
+
+Receipt of a TC-U-ABORT indication primitive is described as part of user abort procedure (see 3.4.6.2). If the abort reason is application context name not supported, the responding side may propose an alternative application-context-name in the TC-U-ABORT indication. If an alternative application-context is proposed, the receiving entity shall check this name and if it can be supported a new dialogue may be established.
+
+### **3.4.3.6 Receipt of a TC-P-ABORT ind**
+
+Receipt of a TC-P-ABORT indication primitive is described as part of provider abort procedure (see 3.4.7.1).
+
+## **3.4.4 Dialogue continuation**
+
+Once established the dialogue is said to be in a continuation phase.
+
+Both application processes can request the transfer of INAP APDUs until one of them requests the termination of the dialogue.
+
+### **3.4.4.1 Sending entity**
+
+SACF shall process any component handling request primitives as described in 3.4.8.
+
+After processing the last component handling request primitive, SACF shall issue a TC-CONTINUE request primitive.
+
+#### **3.4.4.2 Receiving entity**
+
+On receipt of a TC-CONTINUE indication primitive SACF shall accept zero, one or several TC component handling indication primitives and process them as described in 3.4.8.
+
+#### **3.4.5 Dialogue termination**
+
+Both the dialogue-initiator and the dialogue-responder have the ability to request the termination of a dialogue after it has been established when no dialogue is to be established or when a dialogue is no longer to be maintained according to the rules as stated in 3.4.1 and 3.4.2.
+
+The dialogue termination procedure is driven by the following events:
+
+- A TC-END request primitive.
+- A TC-END indication primitive.
+
+##### **3.4.5.1 Sending of TC-END request**
+
+When the dialogue shall no longer be maintained, SACF shall process any component handling request primitives as described in 3.4.8
+
+After processing the last component handling request primitive (if any), SACF shall issue a TC-END request primitive with the release method parameter set to "basic end" or "pre-arranged release", according to the rules as stated in 3.4.1 and 3.4.2.
+
+When no dialogue is to be established, refer to 3.4.3.1 and 3.4.3.2.
+
+##### **3.4.5.2 Receipt of a TC-END indication**
+
+On receipt of a TC-END indication primitive, the SACF shall accept any component handling indication primitives and process them as described in 3.4.8.
+
+After processing the last component handling primitive all dialogue related resources are released.
+
+#### **3.4.6 User Abort**
+
+Both the dialogue-initiator and the dialogue-responder have the ability to abort a dialogue at any time.
+
+The user abort procedure is driven by one of the following events:
+
+- A TC-U-ABORT request primitive.
+- A TC-U-ABORT indication primitive.
+
+##### **3.4.6.1 Sending of TC-U-ABORT request**
+
+After issuing a TC-U-ABORT request primitive, all dialogue related resources are released.
+
+##### **3.4.6.2 Receipt of a TC-U-ABORT indication**
+
+On receipt of a TC-U-ABORT indication all dialogue related resources are released.
+
+#### **3.4.7 Provider Abort**
+
+TC has the ability to abort a dialogue at both the dialogue-initiator side and the dialogue-responder side.
+
+The provider abort procedure is driven by the following event:
+
+- A TC-P-ABORT indication primitive.
+
+##### **3.4.7.1 Receipt of a TC-P-ABORT indication**
+
+On receipt of a TC-P-ABORT indication, all dialogue related resources are released.
+
+### **3.4.8 Procedures for INAP operations**
+
+This subclause describes the procedures for INAP operations.
+
+#### **3.4.8.1 Operation invocation**
+
+SACF shall build an operation argument from the parameters received and request the invocation of the associated operation using the TC-INVVOKE procedure. If a linked ID parameter is inserted in the primitive, this indicates a child operation and implies that the operation is linked to a parent operation.
+
+#### **3.4.8.2 Operation invocation receipt**
+
+On receipt of a TC-INVVOKE indication primitive, SACF shall:
+
+- If the operation code does not correspond to an operation supported by the application-context, request the transfer of a reject component using the TC-U-REJECT request primitive, with the appropriate problem code (unrecognized operation).
+- If a linked ID is included, perform the following checks: if the operation referred to by the linked ID does not allow linked operations or if the operation code does not correspond to a permitted linked operation, or if the parent operation invocation is not active, issue a TC-U-REJECT request primitive with the appropriate problem code (linked response unexpected or unexpected linked operation).
+- If the type of the argument is not the one defined for the operation, request the transfer of a reject component using the TC-U-REJECT request primitive, with the appropriate problem code (mistyped parameter).
+- If the operation cannot be invoked because the INAP related dialogue is about to be released, requests the transfer of the reject component using the TC-U-REJECT request primitive with the problem code (Initiating Release).
+- If sufficient INAP related resources are not available to perform the requested operation, request the transfer of a reject component using the TC-U-REJECT request primitive with the problem code (Resource Limitation).
+- Otherwise, accept the TC-INVVOKE indication primitive. If the operation is to be user confirmed, SACF waits for the corresponding response.
+
+#### **3.4.8.3 Operation Response**
+
+For user confirmed operations, SACF shall:
+
+- If no error indication is included in the response to a class 1 or 3 operation, construct a result information element from the parameters received and request its transfer using the TC-RESULT-L service.
+- If an error indication is included in the response to a class 1 or 2 operation, construct an error parameter from the parameters received and request its transfer using the TC-U-ERROR request primitive.
+
+#### **3.4.8.4 Receipt of a response**
+
+##### **3.4.8.4.1 Receipt of TC-RESULT-NL indication**
+
+On receipt of a TC-RESULT-NL indication, SACF shall:
+
+- Request the transfer of a reject component using the TC-U-REJECT request primitive with the appropriate problem code (mistyped parameter).
+
+##### **3.4.8.4.2 Receipt of TC-RESULT-L indication**
+
+On receipt of a TC-RESULT-L indication, SACF shall:
+
+- If the type of the result parameter is not the one defined for the result of this operation, request the transfer of a reject component using the TC-U-REJECT request primitive with the appropriate problem code (mistyped parameter).
+- Otherwise, accept the TC-RESULT-L indication primitive.
+
+#### **3.4.8.4.3 Receipt of TC-U-ERROR indication**
+
+On receipt of a TC-U-ERROR indication, SACF shall:
+
+- If the error code is not defined for the SACF or is not one associated with the operation referred to by the invoke identifier, request the transfer of a reject component using the TC-U-REJECT request primitive, with the appropriate problem code (unrecognized error or unexpected error).
+- If the type of the error parameter is not the one defined for this error, request the transfer of a reject component using the TC-U-REJECT request primitive, with the appropriate problem code (mistyped parameter).
+- Otherwise, accept the TC-U-ERROR indication primitive.
+
+#### **3.4.8.4.4 Receipt of TC-U-REJECT indication**
+
+On receipt of a TC-U-REJECT indication primitive which affects a pending operation, SACF shall accept the TC-U-REJECT indication primitive.
+
+#### **3.4.8.4.5 Receipt of a TC-L-REJECT indication**
+
+This event occurs when the local TC detects a protocol error in an incoming component which affects an operation.
+
+On receipt of a TC-L-REJECT indicating "return result problem, return error unexpected", SACF shall inform the application process.
+
+On receipt of a TC-L-REJECT indicating "return error problem, return error unexpected", SACF shall inform the application process.
+
+Note that when the problem code indicates a general problem, it is considered that the event cannot be related to an active operation even if the invoke Id is provided by TC. This is because it is unclear whether the invoke Id refers to a local or remote invocation. The behaviour of SACF in such a case is described in 3.4.8.5.3.
+
+#### **3.4.8.4.6 Receipt of a TC-L-CANCEL indication**
+
+On receipt of a TC-L-CANCEL indication, the SACF shall:
+
+- If the associated operation is a class 1 operation, inform the application process.
+- If the associated operation is a class 2 operation and no linked operations are defined for this operation, ignore the primitive.
+- If the associated operation is a class 2 operation and has linked operations but none of them has been invoked, inform the application process.
+- If the associated operation is a class 2 operation and a linked operation invocation has already been received in response to this operation, ignore the primitive.
+- If the associated operation is a class 3 operation, inform the application process.
+- If the associated operation is a class 4 operation, ignore the primitive.
+
+### **3.4.8.5 Other events**
+
+This subclause describes the behaviour of SACF on receipt of a component handling indication primitive which cannot be related to any operation or which does not affect a pending one.
+
+#### **3.4.8.5.1 Receipt of a TC-U-REJECT indication**
+
+On receipt of a TC-U-REJECT indication primitive which does not affect an active operation (i.e. indicating a return result or return error problem), it is up to the application process to abort, continue or terminate the dialogue, if not already terminated by the sending application process according to the rules as stated in 3.4.2. This is also applicable for invoke problems related to a class 4 linked operation.
+
+#### **3.4.8.5.2 Receipt of a TC-R-REJECT indication**
+
+On receipt of a TC-R-REJECT indication (i.e. when a protocol error has been detected by the peer TC entity) which does not affect an active operation, it is up to the application process to abort, continue or terminate the dialogue, if not already terminated by the sending application process according to the rules as stated in 3.4.2.
+
+#### **3.4.8.5.3 Receipt of a TC-L-REJECT indication**
+
+On receipt of a TC-L-REJECT indication primitive (i.e. when a protocol error has been detected by the local TC entity) which cannot be related to an active operation, it is up to the application process to continue, or to terminate the dialogue and implicitly trigger the transmission of the reject component or to abort the dialogue.
+
+#### **3.4.8.5.4 Receipt of a TC-NOTICE indication**
+
+This informs the SACF that a message cannot be delivered by the Network Layer, this can only occur if the Return Option has been set (see 3.4.9.1.8). It is for the application process to decide whether to terminate the dialogue or retry.
+
+### **3.4.9 Mapping on to TC services**
+
+#### **3.4.9.1 Dialogue control**
+
+The TC-UNI service is not used by INAP.
+
+##### **3.4.9.1.1 Destination address**

+## Annex A
+
+### INAP SDL Diagrams
+
+(This annex forms an integral part of this Recommendation)
+
+#### A.1 Introduction
+
+This annex contains SDL diagrams for the FSMs for the SSF, assisting/handoff SSF, SCF and SRF, as described in the text and Figures of 3.1.1.5, 3.1.1.6, 3.1.2 and 3.1.3, together with information from relevant detailed operation procedures. SDL diagrams for the SDF-related states of the SCF and for the SDF itself are contained in Annex B.
+
+Notes on the diagrams give further details where necessary. The SDL diagrams are at the same level of detail as the relevant text and figures, and do not contain anything not in the main body of this Recommendation unless specifically noted.
+
+The SDL used is compliant with the latest Recommendations for SDL [Recommendation Z.100 (1993)], but no symbols are used which are not contained in Recommendation Z.100 (1988).
+
+In the case of inconsistency between SDL diagrams and text, text shall be taken as correct.
+
+#### A.2 SDL diagrams
+
+The SDL in these diagrams is very high-level. It is incomplete in that data declarations are given only for timers and signals, but data carried by the signals is not declared.
+
+Names used for operations are exactly those of this Recommendation, and other locally-defined names in general relate to event names used in this Recommendation. In some cases, however, new names have been introduced for signals where this Recommendation does not provide a name. Where operation names have been split to contain them within a symbol, the SDL technique of breaking lines with an underline followed by a space is used; this combination is ignored in SDL so A\_B is the same name as AB.
+
+In general receipt of a signal (input) from an FE outside the FE being modelled will require some service logic processing, but the detail of such processing is not of interest to the FSM (only its results). The existence of this service logic processing has been shown by inclusion of a general procedure called Process\_Input. In other places SDL tasks are used to indicate the scope of processing required.
+
+It should be noted that in SDL the word "reset" applied to timers means to stop the timer, not restart it. "Set" in SDL means both start and restart a timer.

+State transition diagram for INAP\_SSF process. It starts at an initial state leading to 'Idle'. From 'Idle', two transitions are possible: 'TDP\_R' and 'TDP\_N'. The 'TDP\_R' path leads to 'Process\_Input', then 'TDPEvent to SCF' (with a note about TDP-R detection), then 'SET (NOW + value 1, Tssf)', and finally 'Waiting For Instructions'. The 'TDP\_N' path leads to 'Process\_Input', then 'TDPEvent to SCF' (with a note about TDP-N detection), then 'Restart\_Processing TO CCF', and finally 'Idle'.

+
+The diagram is a State Transition Diagram (STD) for the process INAP\_SSF. It begins with an initial state 'Waiting For Instructions' (oval). A dashed line from this state points to a note: 'Also appears on Pages 5, 7, 8'. From the initial state, two transitions lead to different paths. The left path goes through a transition (chevron) labeled 'Call-processing signals from SCF' (indicated by a dashed line) to a state 'Process\_Input' (double rectangle). From 'Process\_Input', a transition leads to a decision diamond 'EDP armed'. If 'Yes', it goes to state 'Monitoring' (oval). If 'No', it goes to another decision diamond 'Report pending'. If 'Yes', it goes to 'Monitoring'. If 'No', it goes to state 'Idle' (oval). The right path from the initial state goes through a transition (chevron) labeled 'ReleaseCall /\* from SCF \*/' to another state 'Process\_Input' (double rectangle). From this 'Process\_Input', a transition leads to a state 'TerminateCall TO CCF' (pentagon). From 'TerminateCall TO CCF', a transition leads to a decision diamond 'Report pending'. If 'Yes', it goes to a state 'Call\_Information\_Report TO SCF' (pentagon). If 'No', it goes directly to state 'Idle' (oval). Both 'Call\_Information\_Report TO SCF' and the 'No' path from 'Report pending' lead to the final 'Idle' state (oval).

+
+The diagram illustrates the state transitions for the INAP\_SSF process. It begins in the **Monitoring** state, which is also referenced on pages 12 and 13. From **Monitoring**, three transitions are available: **ReleaseCall** (from SCF), **TC\_END, TC\_ABORT** (from SCF), and **Cancel\_(allRequests)** (from SCF). Each transition leads to a **Process\_Input** block. The **ReleaseCall** path leads to **TerminateCall TO CCF**, which then leads to a decision diamond labeled **"Report pending"**. The **TC\_END, TC\_ABORT** path leads directly to the same **"Report pending"** decision. The **Cancel\_(allRequests)** path leads to **Process\_Input** and then to the **Idle** state. From the **"Report pending"** decision, a **"Yes"** response leads to **Call\_Information\_Report TO SCF**, which then leads to the **Idle** state. A **"No"** response from the decision also leads directly to the **Idle** state. A note indicates that **ApplyChargingReport** is treated the same way as **CallInformation Report**.

The first transition is Charging\_Event, which is associated with a note "Previously requested". This leads to Process\_Input, associated with a note "Service logic handles event as required". The next transition is Apply\_Charging, labeled "Report to SCF". This leads to a decision diamond "Connection Configuration changed". If the answer is "No", the flow goes to a state labeled "-". If the answer is "Yes", it proceeds to another decision diamond "EDPs armed". If "Yes", it goes to "-". If "No", it proceeds to a third decision diamond "Reports pending". If "Yes", it goes to a state transition box "SET (NOW + VALUE, Tssf)", which is associated with a note "If required VALUE is current value". From this box, it goes to "-". If "No", it returns to the Idle state. The state labeled "-" is associated with a note "Return to previous state".

+The diagram is a state transition diagram for the SRF-FSM. It consists of the following elements:
+
+- States:**
+  - An initial state represented by an oval at the top.
+  - An **Idle** state represented by a double-oval shape, with a dashed line pointing to a box labeled **State 1**.
+  - A **Connected** state represented by a double-oval shape at the bottom.
+- Transitions:**
+  - A transition from the **Idle** state to the **Connected** state, triggered by **Connect\_Request\_from\_SSF** (represented by a chevron shape). This transition is associated with the action **E1; bearer connection request** (shown in a box to the right).
+  - A transition from the **Connected** state back to the **Idle** state, triggered by **Process\_Input** (represented by a double rectangle shape).
+  - A self-loop transition on the **Connected** state, triggered by **SET (NOW + value, Tsrf)** (represented by a rectangle shape).

+## Annex B
+
+### Description of the SCSM (SDF-related states) and of the SDSM
+
+(This annex forms an integral part of this Recommendation)
+
+This description includes a text and an SDL description.
+
+#### B.1 Description of the Process SCSM
+
+When the Application process at the SCF side decides to create a binding between an SCF and the SDF on behalf of the end user, then a SCSM process instance shall be created by the application process. Two processes occur in the course of establishing a binding namely authentication and version negotiation. Authentication shall be concerned with the user and the directory. The standard shall provide the following methods of authentication techniques namely:
+
+- the use of passwords; or
+- the use of protected passwords.
+
+When a SCSM process instance is created it shall be put in the "Idle" state.
+
+##### B.1.1 State 1 – "Idle"
+
+###### B.1.1.1 Normal procedures
+
+When the SCSM process instance is in the state "Idle" and a need of the application process to interrogate an SDF exists, a Bind.inv primitive shall be sent by the SCF Application process. The bind argument shall be stored and a timer  $T_1$  shall be started. This event shall cause a transition to the state "Wait\_for\_Subsequent\_Requests" and other events are awaited. The timer  $T_1$  is started in order to supervise the state "Wait\_for\_Subsequent\_Requests" and will ensure that the SCSM process is deleted when the communication with the application process is interrupted. The Dialogue handling services of TC shall be used to support the DirectoryBind operation and to trigger the sending of the associated APDU to the peer SDF process instance.
+
+###### B.1.1.2 Exceptional procedures
+
+None identified.
+
+##### B.1.2 State 2 – "Wait for subsequent requests"
+
+###### B.1.2.1 Normal procedures
+
+In this state, subsequent operations to be sent with the Bind operation (in the same message) to the SDF are expected. The following normal events are considered in this state:
+
+- When a Op.inv primitive is received from the application process a component handling primitive TC-INVOKED req shall be sent to the TC and the process instance shall return to the "Wait\_for\_Subsequent\_Requests" state. This operation shall be sent to the SDF in a message containing a Bind argument. The SCSM process instance shall wait for a Delimiter primitive response from the application process. The operations to be carried by the TC-INVOKED req primitive can be a search, modifyEntry, addEntry or removeEntry.
+- When a Delimiter primitive is received from the application process the SCSM process instance shall stop the timer  $T_1$ , shall start timer  $T_2$  and shall send a dialogue handling primitive TC-BEGIN req to TC. Once the TC-BEGIN req. primitive is received by the TC, a message containing the Bind argument and other operation arguments if any shall be sent to the SDF. This event shall cause the SCSM process instance to transit to the State 3 "Wait\_for\_Bind\_result". The SCSM process instance shall wait for the response from the SDF. The timer  $T_2$  is started in order to supervise the state "Wait\_for\_Bind\_result" and will ensure that the SCSM process is deleted when the communication with the peer SDF application process is interrupted.

+The diagram illustrates the SCF-SDF Model. It features five main components: SCF Application, SDF Application, SCSM, SDSM, and TCAP. The SCF Application and SDF Application are at the top, each connected to its respective middle component (SCSM and SDSM). The SCF Application sends 'Bind.res, Bind.err, U\_Abort, Process\_error, Op.res, Op.err, Op.rej' to SCSM, which in turn sends 'Bind.inv, Unbind.inv, Delimitor, Op.inv, AP\_U\_Abort' back. The SDF Application sends 'Bind.inv, Unbind.inv, Op.inv, U\_Abort' to SDSM, which responds with 'Bind.res, Bind.err, AP\_U\_Abort, Delimitor, Op.res, Op.err, Op.rej'. Both SCSM and SDSM are connected to the bottom TCAP component. SCSM sends 'TC\_INVOKE, TC\_U\_ABORT, TC\_END, Dialogue\_terminated, TC\_CONTINUE, TC\_BEGIN' to TCAP, which responds with 'TC\_CONTINUE, TC\_U\_ABORT, TC\_RESULT, TC\_ERROR, TC\_CANCEL, TC\_REJECT'. SDSM sends 'TC\_INVOKE, TC\_U\_ABORT, TC\_END, TC\_CONTINUE, TC\_BEGIN' to TCAP, which responds with 'TC\_CONTINUE, TC\_U\_ABORT, TC\_RESULT, TC\_ERROR, TC\_REJECT'.

+### B.1.2.2 Exceptional procedures
+
+- When the timer T<sub>1</sub> expires and the SCSM process instance is in the "Wait\_for\_Subsequent\_Request" the "Dialogue terminated" primitive shall be sent to the Component Coordination of the TC in order to discard the eventual directory invoke operation stored and awaiting transmission, a "Process\_error" primitive shall be sent to the SCF application process and the SCSM process shall be terminated.
+- When the SCF application process wants to abort the communication with the peer SDF it shall send a "AP\_U\_Abort" primitive to SCSM process instance, this process instance shall send a "Dialogue terminated" primitive to the Component Coordination of the TC in order to discard the eventual directory invoke operation stored and awaiting transmission and the SCSM process shall be terminated.
+
+### **B.1.3 State 3 – "Wait\_for\_Bind\_result"**
+
+#### **B.1.3.1 Normal procedures**
+
+In this state, the SCF is waiting for the response from the SDF. The reception of the response in the TC-CONTINUE ind primitive from TC to the Bind operation previously issued to the SDF, shall stop the timer T<sub>2</sub>, shall send a Bind.res primitive to the application process and shall cause a transition of the SCF to the state "SDF Bound".
+
+#### **B.1.3.2 Exceptional procedures**
+
+- When the timer T<sub>2</sub> expires and the SCSM process instance is in the "Wait\_for\_Bind\_result", the "TC-U-ABORT" req primitive shall be sent to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SDF process, a "Process\_error" primitive shall be sent to the SCF application process and the SCSM process shall be terminated.
+- When the SCF application process wants to abort the communication with the peer SDF it shall send a "AP\_U\_Abort" primitive to SCSM process instance, this process instance shall send a "TC-U-ABORT" req primitive to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SDF process and the SCSM process shall be terminated.
+- When a TC-U-ABORT ind. primitive is received from the TC having a directoryBind error operation component from the peer SDF process, this operation shall be passed in the "Bind.err" primitive to the application process and the SCSM process shall be terminated.
+- When a TC-U-ABORT ind. primitive is received from the TC without having a directoryBind error operation component from the peer SDF process, a "U\_Abort" primitive shall be passed to the application process and the SCSM process shall be terminated.
+
+### **B.1.4 State 4 – "SDF Bound"**
+
+#### **B.1.4.1 Normal procedures**
+
+In this state, the SCF has established an authenticated access to the SDF, and is waiting for requests to the SDF from the service logic or is waiting for responses to the operations previously issued to the SDF:
+
+- When a Op.inv primitive is received from the application process, a component handling primitive TC-INVOKED req shall be sent to the TC and the process instance shall return to the "SDF\_Bound" state. The SCSM process instance shall wait for a Delimiter primitive response from the application process. The operations to be carried by the TC-INVOKED req primitive can be a search, modifyEntry, addEntry or removeEntry.
+- When a "Delimiter" primitive is received from the application process, then a TC-CONTINUE req primitive will be sent to the TC in order to forward the received operation(s) to the remote SDF application process instance.
+- When a TC-RESULT ind primitive is received from the TC caused by the successful reception of a response to the operation previously issued to the SDF, the SCSM process instance shall send the operation return result to the application process and shall return to the same state.
+- When a TC-U-ERROR ind primitive is received from the TC indicating that the invoked operation from the SCF application process has failed at the peer SDF side, the SCSM process shall send the operation return error to the application process and shall return to the same state.
+- When the TC-L-REJECT ind primitive is received indicating that the TC Component sub-layer received an invalid operation, then the SCSM process instance shall send an operation reject to the application process and shall return to the same state.
+
+- When the TC-R-REJECT ind primitive is received from the TC indicating that the operation was rejected by the remote Component sub-layer, then the SCSM process instance shall send an operation reject to the application process and shall return to the same state.
+- When the TC-U-REJECT ind primitive is received from the TC indicating that the operation was rejected by the remote application process instance, then the SCSM process instance shall send an operation reject to the application process and shall return to the same state.
+- When the TC-L-CANCEL ind primitive is received from the TC indicating that the operation invocation was locally terminated due to a time-out condition, then the SCSM process instance shall inform the application process and shall return to the same state.
+- When an Unbind.inv primitive is received from the SCF application process caused by the need to terminate the authenticated access to the SDF, a TC-END req primitive shall be sent to the TC in order to end the dialogue with the remote SDF application process and the SCSM process instance shall be terminated.
+
+#### **B.1.4.2 Exceptional procedures**
+
+- When the SCF application process wants to abort the communication with the peer SDF, it shall send a "AP\_U\_Abort" primitive to SCSM process instance, this process instance shall send a "TC-U-ABORT" req primitive to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SDF process and the SCSM process shall be terminated.
+- When a TC-U-ABORT ind. primitive is received from the TC, a "U\_Abort" primitive shall be passed to the application process and the SCSM process shall be terminated.
+
+### **B.2 Description of the Process SDSM**
+
+The SDF directory abstract service is defined in terms of a number of operations which the SDF can perform at the request of the SCF on behalf of the end user. Before invoking these operations, the SCF shall perform a bind operation at some access point. The SCF can then invoke operations, each invocation shall identify the particular operation to be performed and shall carry the arguments which define the actual request.
+
+#### **B.2.1 State 1 – "Idle"**
+
+##### **B.2.1.1 Normal procedures**
+
+When the Dialogue handling services of TC sends a TC-BEGIN ind. containing the DirectoryBind operation, a SDSM process instance shall be created, a "Bind.inv" primitive shall be sent to the application process and timer T<sub>3</sub> shall be started. This event shall cause a transition to the state "Bind pending". The timer T<sub>3</sub> is started in order to supervise the state "Bind pending" and shall ensure that the SDSM process is deleted when the communication with the application process is interrupted.
+
+##### **B.2.1.2 Exceptional procedures**
+
+None identified.
+
+#### **B.2.2 State 2 – "Bind Pending"**
+
+##### **B.2.2.1 Normal procedures**
+
+In this state, a Bind request has been received from the SCF. The SDF is performing the SCF access control procedures behind the Bind operation (e.g. access authentication). There may also be a case such that the Bind operation is a dummy one. Then, the access authentication is not required. Two events are considered in this state:
+
+- When the TC-INVOKE ind. component handling primitive is received caused by the reception of operations before the result from the Bind operation is sent from the application process, a "Op.inv" primitive shall be sent to the application process and the SDSM process instance shall return to the "Bind pending" state.
+- When the bind request succeeds, the SDF application process shall send a "Bind.res" primitive to the SDSM process instance containing the directoryBind return result. On receipt of the "Bind res" primitive the SDSM process instance shall stop timer T<sub>3</sub>, store the information locally until a "Delimitor" primitive is received from the application process and shall transit to the "SCF bound" state.

The SDSM process instance shall send a "TC-U-ABORT" req primitive to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SCF process and the SDSM process shall be terminated.
+- When the timer T<sub>3</sub> expires and the SDSM process instance is in the "Bind\_pending" state, the "TC-U-ABORT" req primitive shall be sent to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SCF process, a "Process\_error" primitive shall be sent to the SDF application process and the SDSM process shall be terminated.
+- When the SDF application process wants to abort the communication with the peer SCF it shall send a "AP\_U\_Abort" primitive to SDSM process instance, this process instance shall send a "TC-U-ABORT" req primitive to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SCF process and the SDSM process shall be terminated.
+
+### **B.2.3 State 3 – "SCF Bound"**
+
+#### **B.2.3.1 Normal procedures**
+
+In this state, the access of the SCF to the SDF is authorized and operations coming from the SCF are accepted. Besides waiting for requests from the SCF, the SDF can also send in that state responses to previously issued operations. The following normal events are considered in this state:
+
+- When a Op.res primitive is received from the application process indicating that an operation is successfully executed, a component handling primitive TC-RESULT req shall be sent to the TC and the process instance shall return to the "SCF bound" state. The SDSM process instance shall wait for a Delimiter primitive response from the application process to send a TC-CONTINUE req primitive to the TC Dialogue Handling entity so that the TC can forward this return result to the peer SCSM process instance. The return results to be carried by the TC-RESULT req primitive can be originated from previously received search, modifyEntry, addEntry or removeEntry operations.
+- When a Op.err primitive is received from the application process indicating that an previously received operation cannot be successfully executed, a component handling primitive TC-U-ERROR req shall be sent to the TC and the process instance shall return to the "SDF bound" state. The SDSM process instance shall wait for a Delimiter primitive response from the application process to send a TC-CONTINUE req primitive to the TC Dialogue Handling entity so that the TC can forward this return error to the peer SCSM process instance. The return errors to be carried by the TC-U-ERROR req primitive can be originated from previously received search, modifyEntry, addEntry or removeEntry operations.
+- When a Delimiter primitive is received from the application process, the SDSM process instance shall send a dialogue handling primitive TC-CONTINUE req to TC. Once the TC-CONTINUE req. primitive is received by the TC, a message containing the Bind return result, return error or reject argument previously stored, if not already sent, and other operation return result, return error or reject arguments if any shall be sent to the SCF. This event shall cause the SDSM process instance to return to the State "SCF bound".
+- When a TC-END ind primitive is received from the Dialogue Handling of the TC caused by the reception of the Unbind operation from the SCF, the SDSM process instance shall send a "Unbind.inv" primitive to the application process and shall terminate the SDSM process instance. The SCF-SDF association shall be ended and all associated resources are released.
+- When a TC-INVOKED ind component handling primitive is received from the TC a "Op.inv" primitive shall be sent to the application process and the SDSM process instance shall return to the "SCF bound" state.
+
+#### **B.2.3.2 Exceptional procedures**
+
+- When a Op.rej primitive is received from the application process indicating that an previously received operation is rejected, a component handling primitive TC-U-REJECT req shall be sent to the TC and the process instance shall return to the "SCF bound" state. The SDSM process instance shall wait for a Delimiter primitive response from the application process to send a TC-U-CONTINUE req primitive to the TC Dialogue Handling entity so that the TC can forward this reject to the peer SCSM process instance. The reject to be carried by the TC-U-REJECT req primitive can be originated from previously received search, modifyEntry, addEntry or removeEntry operations.
+- When a TC-U-ABORT ind. primitive is received from the TC a "U\_Abort" primitive shall be passed to the application process and the SDSM process shall be terminated.
+- When the SDF application process wants to abort the communication with the peer SCF it shall send a "AP\_U\_Abort" primitive to SDSM process instance, this process instance shall send a "TC-U-ABORT" req primitive to the Dialogue Handling of the TC in order to abort the started dialogue with the peer SCF process and the SDSM process shall be terminated.

+
+The flowchart illustrates the state transitions for Process SDSM. It begins with an initial state (oval) leading to an end state (oval), which then leads to the TC\_BEGIN transition (chevron). This is followed by the Bind.inv transition (chevron), the Start Timer T3 action (rectangle), and the Bind pending state (oval). From Bind pending, four transitions are possible: TC\_INVOKE (chevron), Bind.err (chevron), AP\_U\_Abort (chevron), and T3 Expiry (chevron). TC\_INVOKE leads to the Op.inv transition (chevron), which ends in a state represented by a dash (oval). Bind.err, AP\_U\_Abort, and T3 Expiry all lead to a TC\_U\_ABORT transition (chevron), each of which ends in an error state represented by a circled X. The T3 Expiry path also includes a Process\_error transition (chevron) before the final error state.

+## Appendix I
+
+### Service data modelling
+
+(This appendix does not form an integral part of this Recommendation)
+
+This appendix outlines the required steps and provides a set of guidelines and examples for the definition of a service data model and the mapping of it onto the information model defined in 2.2.2.3. These guidelines and examples provide a simple mechanism which addresses the items in I.1.1 and I.2.1.
+
+Additional tools (e.g. attribute context specifications) may also provide solutions to data modelling, however this appendix does not address these tools.
+
+#### I.1 Review of need for Service data modelling
+
+The adoption of the X.501 information model as the data model for representing service data within the SDF, together with the use of X.511 operations for the interface between the SCF and SDF, has opened up the question of how IN Service data should be mapped onto this information model.
+
+Inappropriate mapping of service data onto the X.500 information model used within the SDF can dramatically increase the amount of information which must be transferred across the SCF-SDF interface (in certain cases even exceeding the capacity of the TCAP link). In addition to higher interface traffic, the choice of mapping can also affect the amount of data processing which must be performed by the Functional Element Actions (FEA) within the SCF, to the point of making the SCF-FEA implementations dependent on the service data.
+
+This subclause outlines a simple set of mapping rules which can be applied to service data to both minimize SCF-SDF interface traffic and to maintain service-independent handling of data.
+
+### **I.1.1 General modelling issues**
+
+There are three general requirements to keep in mind when organizing the IN Service data into the X.500 information model. Each of these requirements should be given equal weight.
+
+- **Req-1** – Minimize the traffic between the SCF and the SDF.
+
+The SCF-SDF interface will probably be one of the most heavily used interfaces within the IN environment. Each SLPI within the SCF may have to initiate multiple accesses to data stored in the SDF. It is crucial from a performance point of view that the data transfers be kept to a minimum.
+
+- **Req-2** – Minimize the data processing to be done within the SCF.
+
+Data processing within the SCF is performed by the FEAs defined in Recommendation Q.1214 to handle the Information flows. These FEAs are assumed to be independent of the service for which they are invoked. If the data information being transferred is of the wrong granularity, then service dependent processing may be performed by the FEAs within the SCF. Care must be taken in the design of the X.500 information model for the IN service Data to maintain the service independency of the FEA.
+
+- **Req-3** – Consider the effect of data distribution on the X.500 data management.
+
+For CS-1 systems, the SDF implementation may not be distributed. It should be noted that X.500 systems are inherently distributed data management systems. If the design of the structure of the DIT does not take the distribution of data into account, then the resulting Directory may be unmanageable in terms of the "knowledge" management required to access the Directory information across multiple Directory Service Agents (DSA).
+
+While it can be argued that a centralized Directory implementation need not take distribution into account, performance requirements may require the splitting of the Directory over a number of local DSAs, requiring distribution knowledge to be maintained within each DSA.
+
+### **I.1.2 Service modelling – Defining the information required**
+
+Service modelling is defined in Recommendation Q.1203. It consists of the following steps:
+
+- 1) identifying the service features which comprise the service;
+- 2) identifying the data required to support the needed service feature;
+- 3) identifying the shared data between the service features used by the service;
+- 4) identify the operations and processing required on the service data;
+- 5) identify the Access Control requirements for the service data.
+
+These steps are not covered in this Recommendation. Only the additional steps required to map the Service Data onto the SDF Information Model defined in 2.2 are covered here.
+
+## I.2 Guidelines for building Service Data Models
+
+Once the IN Service Data Model has been defined in terms of the service feature data, it must be mapped onto the X.500 information model. This can be done using the following steps:
+
+- 1) selection of ATTRIBUTES;
+- 2) selection of OBJECT-CLASSs;
+- 3) designing the Service DIT;
+- 4) assignment of Access Control to ATTRIBUTES and OBJECT-CLASSs.
+
+### I.2.1 Selection of ATTRIBUTES
+
+The selection of the ATTRIBUTES is affected by the operations and processing required by the SCF. The following rules are provided to assist the selection process:
+
+- **Guideline 1** – ATTRIBUTES are the smallest addressable unit of IN Service Data which may be transferred across the SCF-SDF interface for processing by the SCF. Structured data types should be avoided in ATTRIBUTE definitions.
+- **Guideline 2** – All the ATTRIBUTES in the Directory which are to be retrieved by the IN service are by preference to be SINGLE-VALUED.
+- **Guideline 3** – If Service Data contains multi-column tables of information (see Figure I.1), then each column<sup>3), 4)</sup> of the table should have an ATTRIBUTE definition.
+
+For example, in Figure I.1a) (Time of Day Routing table) three ATTRIBUTES are defined (StartTime, StopTime and Destination). For Figure I.1b) (Abbreviated Number table) two ATTRIBUTES are defined (AbbrevNo and Destination).
+
+After all ATTRIBUTES have been identified it may be possible to reduce the total number of ATTRIBUTES defined due to identical definitions (e.g. Destination in Figure I.1).
+
+| Start Time | Stop Time | Destination |
+|------------|-----------|-------------|
+| 01:00      | 09:00     | 204 23456   |
+| 09:01      | 15:00     | 204 12345   |
+| 15:01      | 23:00     | 204 23456   |
+|            |           |             |
+
+a) Time of Day Routing table
+
+| Abbreviated No. | Destination |
+|-----------------|-------------|
+| 01              | 204 23456   |
+| 02              | 204 12345   |
+| 03              | 204 23456   |
+|                 |             |
+
+b) Abbreviated Number table
+
+FIGURE I.1/Q.1218  
+Multi-Column Tables in Service Data
+
+3) This assumes that the tables are organized as in Figure I.1 with each row in the table representing a separate group of information. If this organization is reversed, with the columns containing the item groups then each row in the table should have an ATTRIBUTE definition.
+
+4) This guideline is normally used in conjunction with Guideline 6 to determine entry items in the DIT.
+
+### I.2.1.1 ATTRIBUTE Type definitions
+
+An ATTRIBUTE's type is defined by an ASN.1 data definition.
+
+```
+thisAttribute ATTRIBUTE ::= {  
+    ..  
+    WITH SYNTAX thisAttributeASN1DataType,  
+    ..  
+}
+```
+
+An ATTRIBUTE can be defined as a SUB-TYPE of another ATTRIBUTE which means that it must conform to the definition of the parent ATTRIBUTE.
+
+```
+thisAttribute ATTRIBUTE ::= {  
+    ..  
+    SUBTYPE OF anotherAttribute,  
+    ..  
+}
+```
+
+While this provides a convenient way to re-use attribute definitions it can have a side-effect which will impact on Req-1. This is because an X.500 Search operation for a specific AttributeType will return not only the required Attribute's values but also the Attribute Values of those Attributes which are a sub-type of the required Attribute.
+
+It should be noted that Searching for a particular Attribute will not return any of the parent Attribute values.
+
+An ATTRIBUTE can be defined as a Collective Attribute which implies that its values can be shared amongst a number of Directory Entries.
+
+```
+collectiveAttribute ATTRIBUTE ::= {  
+    ..  
+    COLLECTIVE          TRUE,  
+    ..  
+}
+```
+
+Examples of pre-defined attribute can be found in clause 2/X.520.
+
+### I.2.1.2 Defining Permitted Values
+
+There are two methods which can be used to define permitted values for an attribute.
+
+These are:
+
+- 1) restrict the values to a specific set of values,
+- 2) restrict the values to a range on numeric values.
+
+The first case requires two additional attributes:
+
+- a) an attribute to hold the permitted values for the current attribute,
+- b) an Access Control attribute linking the two attributes together. This attribute must have a syntax of ACItem and contain a ProtectedItem field containing the following:
+
+```
+ProtectedItem ::= SEQUENCE {  
+    ..  
+    restrictedBy [10] SET OF RestrictedValue OPTIONAL  
+    ..  
+}
+```
+
+The RestrictedValue contents contain the Attribute Id's of the current Attribute and the Attribute containing the permitted values. Since the RestrictedValue value is part of the Access Control attribute, the ability to change the RestrictedValue value implies the ability to modify all the Access control parameters for the current Entry contained within the Access Control Attribute.
+
+The second case requires only one additional attribute:
+
+- c) an Access Control attribute holding the value range for the current attribute. This attribute must have a syntax of ACItem type and contain a ProtectedItem field containing the following:
+
+```
+ProtectedItem ::= SEQUENCE {  
+    ..  
+    rangeOfValues [7] Filter OPTIONAL  
+    ..  
+}
+```
+
+The Filter contents contain the value range specification the Attribute values. Note that to change one part of the value range requires replacing the entire Filter. Also since the Filter value is part of the Access Control attribute, the ability to change the Filter value implies the ability to modify all the Access control parameters for the current Entry contained within the Access Control attribute.
+
+#### I.2.1.3 Defining Default Values
+
+The default for an attribute type is set at execution time by specifying an Attribute value with a context whose Fallback field is set to TRUE.
+
+Attribute values whose context fallback values are set to TRUE will only be returned if no other attribute values that match the criteria are present.
+
+#### I.2.1.4 Defining MAX Attribute Values
+
+Limiting the number of values which an Attribute may have, is done by specifying an Access Control Attribute containing a ProtectedItem field with the following syntax:
+
+```
+ProtectedItem ::= SEQUENCE {  
+    ..  
+    maxValueCount [8] SET OF MaxValueCount OPTIONAL  
+    ..  
+}
+```
+
+The MaxValueCount contents contain the Attribute Id and the maximum number of values which can be stored in the Attribute. Since the MaxValueCount value is part of the Access Control attribute, the ability to change the MaxValueCount value implies the ability to modify all the Access control parameters for the current Entry contained within the Access Control Attribute.
+
+#### I.2.1.5 Defining Attribute Lifetimes
+
+Attribute lifetimes are set by supplying a TemporalContext for the Attribute Value (at execution time).
+
+#### I.2.1.6 Definition of MATCHING-RULES
+
+MATCHING-RULES define how Attribute values are tested against external values for use in search Filters and Name Matching. An ATTRIBUTE definition has three different types of Matching Rules:
+
+EQUALITY for testing (value == attribute Value).
+
+ORDERING for testing (value < attribute Value).
+
+SUBSTRINGS for testing sub-strings matches.
+
+```
+thisAttribute ATTRIBUTE ::= {  
+    ..  
+    EQUALITY MATCHING RULE equalityMatchingRuleName,  
+    ORDERING MATCHING RULE orderingMatchingRuleName,  
+    SUBSTRINGS MATCHING RULE substringsMatchingRuleName,  
+    ..  
+}
+```
+
+Examples of predefined matching-rules can be found on clause 3/X.520.
+
+#### I.2.1.7 Assigning the ATTRIBUTE Object Identifiers
+
+Each ATTRIBUTE defined is assigned a unique Object Identifier. The form of this Object Identifier should be as follows:
+
+-- IN object identifier prefix
+
+```
+in-oi OBJECT IDENTIFIER ::= { ccitt recommendation q 1218 ... }
+```
+
+-- service attribute definitions
+
+```
+attributeX OBJECT IDENTIFIER ::= { in-oi ServiceID attributeType(4) AttributeID }
+```
+
+-- ServiceID defines the service/service feature to which the attribute belongs.
+
+-- AttributeID defines the Attribute ID within the service: this is assigned by the Service
+
+-- designer.
+
+## I.2.2 Selection of OBJECT-CLASSs
+
+Once the ATTRIBUTES used within the Service Data Model have been identified, then they can be grouped together into specific OBJECT-CLASS elements.
+
+### I.2.2.1 Defining the OBJECT-CLASS
+
+An OBJECT-CLASS defines the specification of a Directory Entry. It consists of a grouping of ATTRIBUTES into a single object class. Each instance of a Directory Entry within the DIT has a unique identity (see 6.2.2.2 for specification). The following rules can be used to assist the OBJECT-CLASS definition:
+
+- **Guideline 4** – Service data values which can share a common unique identity should be grouped as ATTRIBUTES within a Directory Entry (e.g. Service Data, User Data for a service).
+- **Guideline 5** – Service data values which are part of a multi-column Table (see Guideline 3) should be grouped into a single OBJECT-CLASS definition.
+
+An OBJECT-CLASS can be specified as being a SUB-CLASS of another OBJECT-CLASS. In this case the OBJECT-CLASS contains all of the attributes and properties of the parent OBJECT-CLASS.
+
+This is similar to inheritance in C++.
+
+### I.2.2.2 Selecting the RDN (NAME-FORM)
+
+Each OBJECT-CLASS can have a number of attributes designated as possible RDN attributes. This is done using the NAME-FORM specification. When the Directory Entry is created one of these must be designated the active RDN (through the Distinguished Name defined in the AddEntry operation). After the object has been created, only the active RDN can be used in the name matching procedures for locating an object using the access operations (Search, ModifyEntry, RemoveEntry, ...).
+
+Therefore if two objects of the same OBJECT-CLASS are created with the same ATTRIBUTE values but using different active RDNs, then they are considered as two distinct objects within the DIT. If the same RDN had been used for the second object then an object creation error would have occurred.
+
+### I.2.2.3 Assigning the OBJECT-CLASS Object Identifiers
+
+Each OBJECT-CLASS defined is assigned a unique Object Identifier. The form of this Object Identifier should be as follows:
+
+-- *IN object identifier prefix*
+
+**in-oi OBJECT IDENTIFIER ::= { ccitt recommendation q 1218 ... }**
+
+-- *service object-class definitions*
+
+**objectClassX OBJECT IDENTIFIER ::= { in-oi ServiceID objectClass(6) ObjectClassID }**
+
+-- *ServiceID defines the service/service feature to which the attribute belongs.*
+
+-- *ObjectClassID defines the Object Class ID within the service: this is assigned by the Service designer.*
+
+## I.2.3 Defining the DIT
+
+This subclause describes how to build the DIT for an IN Service Data model.
+
+### I.2.3.1 Defining the Object Hierarchy (STRUCTURE-RULES)
+
+The DIT defines a hierarchy of data objects. Each Distinguished name of an object consists of the concatenation of the RDN of the object with the RDN's of the objects in the DIT above the object. The hierarchy of objects within the DIT is defined using STRUCTURE-RULES. Figure I.2 shows how a set of OBJECT-CLASS and STRUCTURE-RULES form the DIT.

+- **Guideline 6** – Where Service Data values share a common structure, but may have multiple value sets (e.g. rows in a time-of-day translation table, user-specific data within a service) these are to be placed in Directory Entries which are subordinate to another Directory Entry (i.e. there is a STRUCTURE-RULE defining the relationship between the Directory Entries).
+- **Guideline 7** – Where multiple sets of Data Entries exist under a specific Data Entry, it is recommended that each of the sets be placed as subordinates to a single data entry which is subordinate to the specific data entry (see Figure I.3). This will allow more efficient searching of the set data entries using the X.500 operations.

+
+### I.2.3.2 Defining alternative naming paths (Aliases)
+
+Once an object class has been instantiated its Distinguished Name is fixed. If an alternative naming path to the object is required, then an Alias object must be defined within the DIT. This Alias object will have its own RDN attributes and will contain a pointer to the object being referenced.
+
+An Alias object is an OBJECT-CLASS which is a subtype of the predefined alias OBJECT-CLASS.
+
+### I.2.3.3 Defining MAX number of subordinate Entries
+
+Limiting the number of subordinate entries an Entry may have, is done by specifying an Access Control Attribute within the Entry containing a ProtectedItem field with the following syntax;
+
+```
+ProtectedItem ::= SEQUENCE {  
+    ..  
+    maxImmSub      [8]  INTEGER OPTIONAL,  
+    ..  
+}
+```
+
+The maxImmSub value contains the maximum number of subordinate entries which may be stored below the current Entry. Note that this limit only applies to the current DSA. Since the maxImmSub value is part of the Access Control attribute, the ability to change the maxImmSub value implies the ability to modify all the Access Control parameters for the Entry contained in the Access Control Attribute.
+
+## I.3 Example Service (UPT Like Service)
+
+This subclause implements an X.500 DIT for a simplified subset of a UPT service using the mapping rules.
+
+### I.3.1 Example Service description
+
+The example service contains the following service features:
+
+- 1) incall;
+- 2) incall Registration;
+- 3) incall Screening;
+- 4) outcall;
+- 5) outcall Screening by location.
+
+These features are described briefly below together with the data information which would be available after the service design stage (ref. I.1.2). The information for each service feature is presented in table form with the following columns:
+
+- |                      |                                                                                                         |
+|----------------------|---------------------------------------------------------------------------------------------------------|
+| – Data:              | The name of the data item.                                                                              |
+| – Definition:        | The definition of the data item type (using ASN.1 style notation).                                      |
+| – Cardinality:       | This defines how different versions of the data item can occur (e.g. one for each user of the service). |
+| – Feature Operation: | This defines what operations (SCF-SDF interface) are used to manipulate the data item.                  |
+| – Access Control:    | This defines what level of access is required by the different levels of service operators.             |
+
+NOTE – This is not intended to be a complete service. Only sufficient detail is provided to show how mapping's onto the SDF Information Model should be performed.
+
+#### I.3.1.1 Service Feature – Incall
+
+Normal Incall operation performs the following routing algorithm:
+
+- 1) if the user has a registered location active, then send call to registered location;
+- 2) if active time-of-day location is active, then route to time-of-day location;
+- 3) if the user has default location, then route to default location;
+- 4) reject call with announcement "user is not available on system".
+
+All defined locations must be one of a pre-defined set of locations for the user.

+
+### I.3.1.2 Service Feature – Incall Registration
+
+This service feature allows the user to register his current location. The current location can either be set to the current terminal (identified by CLI or a defined location). The user can optionally set an expiry time for the current location. If no expiry time is set, a default expiry time is used. The current location must be one of a predefined set of locations.

+
+### I.3.1.3 Service Feature – Incall Screening
+
+This service feature allows the user to reject an incoming call if it is from a specific location. There is a limit to the number of locations which can be used for screening.
+

+
+### I.3.1.4 Service Feature – Outcall
+
+This service feature allows a user to make an outgoing call from a terminal location. The location must be one of the permitted locations for the user. The charge for the call is billed to the service user, not the owner of the terminal.

+
+### I.3.1.5 Service Feature – Outcall screening by location
+
+This service feature provides for preventing outgoing calls to specific locations from proceeding. The list of prescribed locations is different for each location the user can use.
+

+
+### I.3.1.6 General Service Information
+
+The service features have the following relationships for interaction:
+
+- Incall screening is done before Incall;
+- Outcall is done before Outcall Screening by location.
+
+### Additional Service Information
+
+The following additional service parameters are provided:
+
+| Data        | Definition | Cardinality          | Feature Operations | Security Access Control                                                |

+
+## I.3.2 Example Service data modelling
+
+Now that the service data information has been defined, the mapping of the data onto the information model using the steps defined in subclause I.2 can begin.
+
+### I.3.2.1 Selection of Attributes
+
+The first step is to determine the ATTRIBUTE definitions required for the Service Data. For the purposes of defining attribute identifiers, the following object identifier is used:
+
+**exampleAttribute OBJECT IDENTIFIER ::= { in-oi exampleService(1) attributeType(4) }**
+
+### Data – Registered Locations
+
+The Registered Location stores the Locations at which a user may register to receive incoming calls.
+
+|                      |                 |                      |      |                                               |
+|----------------------|-----------------|----------------------|------|-----------------------------------------------|
+| Registered Locations | SET OF Location | One per service user | None | Service: R<br>User management: R/W<br>User: R |
+|----------------------|-----------------|----------------------|------|-----------------------------------------------|
+
+For the purposes of this example the definition of a Location can be considered to be equivalent to a telephone number. This allows the use of SUBTYPE definitions for the service attributes which use Location type definitions from a pre-defined attribute in Recommendation X.520 (telephoneNumber). The definition of the Registered Location attribute therefore becomes:
+
+**regLocations ATTRIBUTE ::= {  
+    SUBTYPE OF telephoneNumber,  
+    COLLECTIVE TRUE,  
+    ID in-at-regLocations }**
+
+The attribute is defined as a Collective Attribute since its values will be shared among a number of Entries in the DIT (refer to I.3.3.2)
+
+## Data – Time Of Day Location
+
+The Time Of Day Location is actually a translation table consisting of 5 columns (startTime.day, startTime.time, stopTime.day, stopTime.time, location).
+
+|                      |                                                                                                                                                                |                          |        |                                               |
+|----------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------|--------|-----------------------------------------------|
+| Time Of Day Location | SEQUENCE {<br>startTime SEQUENCE {<br>day DayOfWeek,<br>time TimeOfDay },<br>stopTime SEQUENCE {<br>day DayOfWeek,<br>time TimeOfDay },<br>location Location } | Many per service<br>user | Search | Service: R<br>User management: R/W<br>User: R |
+|----------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------|--------|-----------------------------------------------|
+
+Using Guideline 3, 5 different ATTRIBUTES are defined, one for each column:
+
+```
+
+startDay ATTRIBUTE ::= {
+  WITH SYNTAX DaysOfWeek -- from proposed X.520 Temporal Context
+  SINGLE VALUE TRUE
+  ID in-at-startDay }
+
+startTime ATTRIBUTE ::= {
+  WITH SYNTAX DayTime -- from proposed X.520 Temporal Context
+  EQUALITY MATCHING RULE numericStringMatch -- from X.520
+  ORDERING MATCHING RULE numericStringOrderingMatch -- from X.520
+  SUBSTRINGS MATCHING RULE numericStringSubstringsMatch -- from X.520
+  SINGLE VALUE TRUE
+  ID in-at-startTime }
+
+stopDay ATTRIBUTE ::= {
+  WITH SYNTAX DaysOfWeek -- from proposed X.520 Temporal Context
+  SINGLE VALUE TRUE
+  ID in-at-stopDay }
+
+stopTime ATTRIBUTE ::= {
+  WITH SYNTAX DayTime -- from proposed X.520 Temporal Context
+  EQUALITY MATCHING RULE numericStringMatch -- from X.520
+  ORDERING MATCHING RULE numericStringOrderingMatch -- from X.520
+  SUBSTRINGS MATCHING RULE numericStringSubstringsMatch -- from X.520
+  SINGLE VALUE TRUE
+  ID in-at-stopTime }
+
+location ATTRIBUTE ::= {
+  SUBTYPE OF telephoneNumber
+  SINGLE VALUE TRUE
+  ID in-at-location }
+```
+
+This Attribute requires additional set-up to restricts it's values to those contained in the Attribute regLocations. This will be done later with an Access Control Attribute in the entry containing both regLocations and location.
+
+## Data – Current Location
+
+The Current Location defines the registered location for a user. It has a specific lifetime.
+
+|                  |          |              |        |                         |
+|------------------|----------|--------------|--------|-------------------------|
+| Current Location | Location | One per user | Search | Service: R<br>User: R/W |
+|------------------|----------|--------------|--------|-------------------------|
+
+The definition of the Current Location attribute therefore becomes:
+
+```
+
+currentLocation ATTRIBUTE ::= {
+  SUBTYPE OF telephoneNumber
+  SINGLE VALUE TRUE
+  ID in-at-cur-location }
+```
+
+This Attribute requires additional set-up to restrict its values to those contained in the Attribute regLocations. This will be done later with an Access Control Attribute in the entry containing both regLocations and currentLocation.
+
+The lifetime for this attribute is specified by providing the value with a temporal context with the endTime field set to the value of either Current Location Expiry or Default Expiry. The selection of which endTime to use is the responsibility of the function setting the attribute value<sup>5)</sup>.
+
+#### Data – Current Location Expiry
+
+The Current Location Expiry data contains the expiration time for the current location data.
+
+|                         |           |              |      |                         |
+|-------------------------|-----------|--------------|------|-------------------------|
+| Current Location Expiry | TimeOfDay | One per user | None | Service: R<br>User: R/W |
+|-------------------------|-----------|--------------|------|-------------------------|
+
+Since the Current Expiry data is only used for setting the lifetime of the currentLocation Attribute, this data is not stored as a separate Attribute within the Directory. Instead, it is present as a TemporalContext value attached to the value of currentLocation. Note that this is an optionally supplied value from the User. If it is not supplied, then the value of Default Expiry is used instead. This selection is managed by the SCF-FEA responsible for managing the Attribute.
+
+#### Data – Default Expiry
+
+The Default Expiry data contains the default expiry time for the current location expiry data.
+
+|                |           |              |      |                                               |
+|----------------|-----------|--------------|------|-----------------------------------------------|
+| Default Expiry | TimeOfDay | One per user | None | Service: R<br>User management: R/W<br>User: R |
+|----------------|-----------|--------------|------|-----------------------------------------------|
+
+Since the Default Expiry data is only used as a default value for setting the lifetime of the currentLocation Attribute, this data is not stored as a separate Attribute within the Directory. Instead, it is present as a TemporalContext value attached to the value of currentLocation. Note that this value is only used if the User does not supply a value for Current Location Expiry. This selection is managed by the SCF-FEA responsible for managing the Attribute.
+
+#### Data – Default Location
+
+The Default Location defines the location to use if all other routing options fail.
+
+|                  |          |              |        |                                               |
+|------------------|----------|--------------|--------|-----------------------------------------------|
+| Default Location | Location | One per user | Search | Service: R<br>User management: R/W<br>User: R |
+|------------------|----------|--------------|--------|-----------------------------------------------|
+
+The definition of the Default Location attribute therefore becomes:
+
+```
+defaultLocation ATTRIBUTE ::= {
+    SUBTYPE OF      telephoneNumber
+    SINGLE VALUE    TRUE
+    ID              in-at-def-location }
+```
+
+<sup>5)</sup> While this may appear to require Service dependent information in the SCF-FEA responsible for managing the Attribute, the lifetime concept is sufficiently general (i.e. can be applied to a large number of attributes independently) that a standard mechanism can be developed to handle it in a service independent manner.
+
+This Attribute requires additional set-up to restricts it's values to those contained in the Attribute **regLocations**. This will be done later with an Access Control Attribute in the entry containing both **regLocations** and **defaultLocation**.
+
+#### Data – Incall Screen List
+
+The Incall Screen List defines a list of Locations, of specified maximum length, from which calls to the user are to be rejected.
+
+|                    |                                        |                      |        |                                       |               |
+|--------------------|----------------------------------------|----------------------|--------|---------------------------------------|---------------|
+| Incall Screen List | SET OF Location<br>SIZE 1..MaxListSize | One per service user | Search | Service:<br>User management:<br>User: | R<br>R/W<br>R |
+|--------------------|----------------------------------------|----------------------|--------|---------------------------------------|---------------|
+
+The Incall Screen List can be considered in two ways, as a table with a single column or as an attribute with multiple values. In this case, since the operation only tests to see if specific values are present and does not retrieve the value, the multi-valued attribute version can be safely used.
+
+The definition of the Incall Screen List attribute therefore becomes:
+
+```
+incallScreenList ATTRIBUTE ::= {
+    SUBTYPE OF      telephoneNumber,
+    ID              in-at-incall-screen }
+```
+
+This attribute requires additional set-up to restrict the number of values which can be stored in the Attribute. This will be done later with an Access Control Attribute in the entry containing IncallScreenList.
+
+#### Data – MaxListSize
+
+The MaxListSize data holds the maximum length of the Incall Screen List.
+
+|             |         |                      |      |                                 |          |
+|-------------|---------|----------------------|------|---------------------------------|----------|
+| MaxListSize | INTEGER | One per service user | None | Service:<br>Service management: | R<br>R/W |
+|-------------|---------|----------------------|------|---------------------------------|----------|
+
+Since the MaxListSize data is only used as a value for the maximum number of values of the **IncallScreenList** Attribute, this data is not stored as a separate Attribute within the Directory. Instead, it is present as a Protected Item of type maxValueCount in an Access Control Attribute in the entry containing **IncallScreenList**.
+
+#### Data – User Id
+
+The User Id data defines the number used to identify the user of a service. When coupled to a service prefix (e.g. 014) it forms a Location.
+
+|         |               |                      |            |                                                              |                    |
+|---------|---------------|----------------------|------------|--------------------------------------------------------------|--------------------|
+| User Id | ServiceNumber | One per service user | match/bind | Service management:<br>Service:<br>User management:<br>User: | R/W<br>R<br>R<br>R |
+|---------|---------------|----------------------|------------|--------------------------------------------------------------|--------------------|
+
+The definition of the User Id attribute therefore becomes:
+
+```
+userId ATTRIBUTE ::= {
+    WITH SYNTAX           NumericString
+    EQUALITY MATCHING RULE numericStringMatch      -- from X.520
+    ORDERING MATCHING RULE numericStringOrderingMatch -- from X.520
+    SUBSTRINGS MATCHING RULE numericStringSubstringsMatch -- from X.520
+    SINGLE VALUE          TRUE
+    ID                    in-at-user-id }
+```
+
+## Data – User Password
+
+The User Password holds the PIN number of a user. It is used to validate registration and Outcall information.
+
+|               |          |                      |            |                                               |
+|---------------|----------|----------------------|------------|-----------------------------------------------|
+| User Password | Password | One per service user | match/bind | Service: R<br>User management: R/W<br>User: R |
+|---------------|----------|----------------------|------------|-----------------------------------------------|
+
+Since this attribute is used in the Bind operation, the User Password must use the userPassword attribute definition defined in 6.3/X.509.
+
+## Data – Outcall Screen List
+
+The Outcall Screen List provides a list of barred locations for each registered location the user has. It is a table with two columns (regLocation, stopList).
+
+|                     |                                                                              |                      |        |                                 |
+|---------------------|------------------------------------------------------------------------------|----------------------|--------|---------------------------------|
+| Outcall Screen List | SET OF {<br>SEQUENCE {<br>stopList SET OF Location,<br>location Location }}} | One per service user | Search | User management: R/W<br>User: R |
+|---------------------|------------------------------------------------------------------------------|----------------------|--------|---------------------------------|
+
+Two attributes are defined for the Outcall Screen List:
+
+```
+outcallScreenLocation ATTRIBUTE ::= {
+    SUBTYPE OF      telephoneNumber
+    SINGLE VALUE    TRUE
+    ID              in-at-outcall-location }
+```
+
+This Attribute requires additional set-up to restrict its values to those contained in the Attribute **regLocations**. This will be done later with an Access Control Attribute in the entry containing both **regLocations** and **outcallScreenLocation**.
+
+```
+outcallScreenStopList ATTRIBUTE ::= {
+    SUBTYPE OF      telephoneNumber
+    ID              in-at-outcall-stoplist }
+```
+
+## Data – Service Key
+
+The Service Key data identifies the Service being used.
+
+|             |           |                 |            |                                                                        |
+|-------------|-----------|-----------------|------------|------------------------------------------------------------------------|
+| Service Key | ServiceId | One per service | match/bind | Service management: R/W<br>Service: R<br>User management: R<br>User: R |
+|-------------|-----------|-----------------|------------|------------------------------------------------------------------------|
+
+The definition of the Service Key attribute therefore becomes:
+
+```
+serviceKey ATTRIBUTE ::= {
+    WITH SYNTAX     Object Identifier
+    SINGLE VALUE    TRUE
+    ID              in-at-service-key }
+```
+
+## Data – User Name
+
+The User Name data hold the name of the User of the Service.
+
+|           |        |                      |       |                           |          |
+|-----------|--------|----------------------|-------|---------------------------|----------|
+| User Name | String | One per service user | match | User management:<br>User: | R/W<br>R |
+|-----------|--------|----------------------|-------|---------------------------|----------|
+
+The definition of the User Name attribute therefore becomes:
+
+```
+
+userName ATTRIBUTE ::= {
+    SUBTYPE OF name,
+    ID in-at-user-name }
+    -- from X.520
+
+```
+
+### I.3.2.2 Selection of Object Classes
+
+Once the ATTRIBUTES have been selected, they can be organized into OBJECT-CLASSs. Using Guideline 5, the following attributes can be grouped together (attributes in [] denotes referenced attributes):
+
+- startDay, startTime, stopDay, stopTime, location, [regLocations];
+- outcallScreenLocation, outcallScreenStopList, [regLocations].
+
+The remaining attributes must be grouped using Guideline-4. Since attributes which share the same cardinality can be said to share the same identity, the following groupings are used:
+
+- serviceKey;
+- currentLocation, defaultLocation, incallScreenList, userId, userPassword, userName, [regLocations].
+
+Attributes can be mandatory or optional within an object-class. From the description of the service logic it can be determined that the currentLocation, defaultLocation attributes are optional. Also, any attribute which is grouped as part of a table must be a mandatory attribute. Other attributes should be made mandatory as well.
+
+The OBJECT-CLASS definitions required are:
+
+```
+
+serviceClass OBJECT-CLASS ::= {
+    MUST CONTAIN serviceKey
+    ID in-oc-service }
+
+serviceUserClass OBJECT-CLASS ::= {
+    MUST CONTAIN userId, userPassword, userName, incallScreenList, reqLocations,
+    MAY CONTAIN currentLocation, defaultLocation
+    ID in-o-service-user }
+
+timeOfDayLocation OBJECT-CLASS ::= {
+    MUST CONTAIN startDay, startTime, stopDay, stopTime, location, reqLocations
+    ID in-oc-time-location }
+
+outcallScreenList OBJECT-CLASS ::= {
+    MUST CONTAIN outcallScreenLocation, outcallScreenStopList, reqLocations
+    ID in-oc-outcall-screen }
+
+```
+
+The definition of the Access Control Attributes used to handle Attribute Access Control has been deferred until the DIT design is complete (see I.3.2.4).
+
+Once the object classes have been defined, the naming attributes for the objects must be assigned. This requires the identification of one of the mandatory attributes which has a unique value for each occurrence of the object.
+
+Examining the objects defined, the following naming attributes can be used:
+
+|                          |                              |
+|--------------------------|------------------------------|
+| <b>serviceClass</b>      | <b>serviceKey</b>            |
+| <b>serviceUserClass</b>  | <b>userId</b>                |
+| <b>timeOfDayLocation</b> | <b>? (Nothing useable)</b>   |
+| <b>outcallScreenList</b> | <b>outcallScreenLocation</b> |
+
+The only object class which has a naming problem is the timeOfDayLocation object. There are two ways around this problem. The first is to define a unique attribute (for example tableRowIndex) to allow naming. This does not affect performance of operations and can be useful in the management operation which are not being considered here.
+
+The second solution is to combine the StartDay, StartTime attributes into a composite attribute, the values of which would then be unique. This method would involve redefining MATCHING-RULEs and some extra processing.
+
+For simplicity the first solution is chosen. The required name forms, with new attribute and revised object-class, are:
+
+```
+tableRowIndex ATTRIBUTE ::= {  
+    WITH SYNTAX Integer  
+    SINGLE VALUE TRUE  
+    ID in-at-maxListValues }  
+  
+timeOfDayLocation OBJECT-CLASS ::= {  
+    MUST CONTAIN tableRowIndex, startDay, startTime, stopDay, stopTime, location,  
+        regLocations  
+    ID in-oc-time-location }  
+  
+serviceName NAME-FORM ::= {  
+    NAMES serviceClass  
+    WITH ATTRIBUTES serviceKey  
+    ID in-nf-service-name }  
+  
+serviceUserName NAME-FORM ::= {  
+    NAMES serviceUserClass  
+    WITH ATTRIBUTES userId  
+    ID in-nf-service-user-name }  
+  
+timeOfDayLocationName NAME-FORM ::= {  
+    NAMES timeOfDayLocation  
+    WITH ATTRIBUTES tableRowIndex  
+    ID in-nf-tod-location-name }  
+  
+outcallScreenName NAME-FORM ::= {  
+    NAMES outcallScreenList  
+    WITH ATTRIBUTES outcallScreenLocation  
+    ID in-nf-outcall-screen-name }
+```
+
+### I.3.2.3 Designing the Service DIT
+
+At this point the design of the DIT can begin. Looking at the cardinality information, the following OBJECT-CLASS relationships can be derived (see Figure I.4):
+
+![A diagram showing object-class relationships. A central oval labeled 'serviceUserClass' is connected to three other ovals: 'serviceClass' to its left, 'timeOfDayLocation' above it, and 'outcallScreenLocation' below it.

+

+FIGURE I.4/Q.1218  
+Object-Class Relationships
+
+Since serviceUserClass has two entry sets below it, Guideline 7 should be invoked which results in adding an extra object level, as shown in Figure I.5:
+
+![A hierarchical diagram showing object class relationships. At the top level is 'serviceClass'. Below it is 'serviceUserClass', connected by a line.

+Object-Class Relationships after Guideline 7
+
+This requires additional object class and attribute definitions. These are:
+
+```
+
+tableHeadIdentifier ATTRIBUTE ::= {
+    WITH SYNTAX      Integer
+    SINGLE VALUE TRUE
+    ID               oi-gen-table-head }
+  
+```
+
+```
+
+tableHead OBJECT-CLASS ::= {
+    MUST CONTAIN     tableHeadIdentifier
+    ID               in-oc-tableHead }
+  
+```
+
+```
+
+tableHeadA OBJECT-CLASS ::= {
+    MUST CONTAIN     tableHeadIdentifier
+    ID               in-oc-tableHeadA }

+```
+
+```
+
+tableHeadA NAME-FORM ::= {
+    NAMES            tableHeadA
+    WITH ATTRIBUTES  tableHeadIdentifier

+  
+```
+
+```
+
+tableHeadB OBJECT-CLASS ::= {

+    WITH ATTRIBUTES  tableHeadIdentifier
+    ID               in-nf-tableHeadNameB }
+  
+```
+
+Therefore the structure rules required to define the DIT structure are:
+
+```
+
+sr-root STRUCTURE-RULE ::= {
+    NAME FORM        serviceClassName
+    ID               sr0 }
+  
+```
+
+```
+
+sr-user STRUCTURE-RULE ::= {
+    NAME FORM      serviceClassName
+    SUPERIOR RULES sr0
+    ID             sr1 }
+
+sr-tableA STRUCTURE-RULE ::= {
+    NAME FORM      tableHeadNameA
+    SUPERIOR RULES sr1
+    ID             sr2 }
+
+sr-tod-location STRUCTURE-RULE ::= {
+    NAME FORM      timeOfDayLocationName
+    SUPERIOR RULES sr2
+    ID             sr3 }
+
+sr-tableB STRUCTURE-RULE ::= {

+    NAME FORM      outcallScreenListName
+    SUPERIOR RULES sr4
+    ID             sr5 }
+
+```
+
+The creation of an Entry of OBJECT-CLASS subEntry holds the specification of the sub-tree to which the collective attributes apply. For the case of the regLocations collective attribute the subEntry is subordinate to an Entry of the OBJECT-CLASS serviceUserClass.
+
+To modify the regLocation Attribute requires the Distinguished Name of the subEntry to be supplied (see Figure I.6).

+### I.3.2.4 Assigning Access control
+
+Note that the DIT is complete, the next required step is to define the Access Control Attribute values for each of the Entries in the DIT. An Entry's Access Control Attribute (entryACI, see 16.5.2/X.501) contains values of type ACIItem which control how the user may access the Attribute values. The following table defines the Access Control required for each of the attributes defined within the DIT.
+
+| Object                | Attribute               | UserClasses defined by X.500 Management |          |             |         |             | Special Protected Items |

+
+Each table column under UserClasses denotes a potential ACIItem value for the entryACI attribute. In practice the values can be combined in a single ACIItem which combines a set of protected items which have the same access permissions for a set of UserClasses. Each ACIItem has a unique identifier field, which can be used to apply Access Control to individual values of the Access Control Attribute itself. This allows different "Users" to modify different Access Control values (which may contain permitted value or size limits) without being able to change other values of the Access Control attribute.
+
+Where permissions are marked with a (\*) this indicates that a special Protected Item of the type specified in the last column (Special Protected Items) must be included in the ACIItem to handle permitted value or value count limit controls.
+
+#### I.4 Defining Contexts
+
+This subclause defines a set of Context types which may be found useful across of range on IN services.
+
+#### **I.4.1 Numerical Index Attribute Value Context**
+
+The Numerical Index Attribute Value Context associates a numerical index with an attribute value.
+
+```
+numericalIndexAVC      ATTRIBUTE-VALUE-CONTEXT ::= {  
+    SYNTAX            INTEGER  
+    id               id-avc-numericalIndex }
+```
+
+An example of use of the numerical index attribute value context is an "abbreviated to expanded number" conversion table, where the index (the context value) is the abbreviated number and the attribute value the expanded number.
+
+Note that a similar String Index Attribute Value Context type could also be defined.

+## **Appendix II**
+
+### **Aspects of the intelligent network interface identified as "For Further Study" (FFS) relative to CS-1**
+
+(This appendix does not form an integral part of this Recommendation)
+
+#### **II.1 General**
+
+##### **II.1.1 General consideration**
+
+This appendix includes call party handling and other issues which were considered to be incomplete when developing the Q.1218 intelligent network interface Recommendation CS-1. Although the material in this appendix is built upon CS-1, the procedures for these capabilities may be undefined and FFS relative to CS-1. The material is included in this appendix to provide some technical basis for future work.
+
+##### **II.1.2 Relationship to other appendices of the Q.1200-Series Recommendations**
+
+This appendix only applies to Q.1218 intelligent network interface Recommendation CS-1. Each of the Q.1200-Series Recommendations includes a specific appendix, if needed.
+
+##### **II.1.3 Format of Document**
+
+This introduction provides an explanation of the purpose and scope of the appendix:
+
+- Subclause II.2 itemizes the operations.
+- Subclause II.3 itemizes the parameters.
+- Subclause II.4 is an ASN.1 module of the operations and parameters.
+- Subclause II.5 includes procedures for the operations.
+
+#### **II.2 Operations**
+
+The operations listed in this subclause are in addition to the operations itemized in clause 2.
+
+##### **II.2.1 Consideration applicable to all operations in this appendix**
+
+The following operations or aspects of the operations are FFS relative to CS-1. These operations rely on CS-1 capabilities for which the corresponding procedures are undefined. Therefore, they are included in this appendix for completeness.
+
+The defined defaults may be incomplete (e.g. Leg ID) and may be dependent on the point in call (PIC).
+
+## **II.2.2 Add party operation**
+
+### **II.2.2.1 Consideration**
+
+The difference between this operation and the attach operation needs to be clarified.
+
+### **II.2.2.2 Description**
+
+SCF → SSF
+
+This operation is used to perform the call processing actions to add all call party connections from one call to another call, then clear the first call (e.g. to create a conference call). From the perspective of the controlling party, this operation effectively bridges two calls.
+
+## **II.2.3 Attach operation**
+
+### **II.2.3.1 Consideration**
+
+The difference between this operation and the add party operation needs to be clarified.
+
+### **II.2.3.2 Description**
+
+SCF → SSF
+
+This operation enables the SCF to request the SSF to include a leg in the current relationship instance. The leg is transferred from another relationship instance, from which it was removed using the detach operation. Notice that detach may also be executed after attach using the same absolute identifier.
+
+## **II.2.4 Change parties operation**
+
+### **II.2.4.1 Description**
+
+SCF → SSF
+
+This operation is used to perform the call processing actions to change a particular party connection from one call to another call. From the perspective of the particular call party, this operation effectively places the first call on hold and retrieves the associated call from hold.
+
+## **II.2.5 Detach operation**
+
+### **II.2.5.1 Consideration**
+
+The difference between this operation and the release call party operation needs to be clarified.
+
+### **II.2.5.2 Description**
+
+SCF → SSF
+
+This operation enables the SCF to request the SSF to remove a leg from one relationship instance and to assign it an absolute (i.e. single network-wide) identifier (Correlation identifier), so that it can be transferred to another relationship instance, to which the leg was/will be attached by means of the attach operation using the same absolute identifier.
+
+## **II.2.6 Hold call party connection operation**
+
+### **II.2.6.1 Description**
+
+SCF → SSF
+
+This operation is used during the active phase of a call between two or more parties to put one party connection on hold.
+
+## **II.2.7 Initiate call attempt operation (for case of more than 1 party)**
+
+### **II.2.7.1 Consideration**
+
+This information flow is included in the main body of Recommendation Q.1214, for the case of creating a call to one call party. The IF is listed in this appendix for the case of creating a call to more than one party, in the same call, which for CS-1 is FFS.
+
+### **II.2.7.2 Description**
+
+SCF → SSF
+
+This operation is used to request the SSF to create a new call to one or more parties using address information provided by the SCF (e.g. predefined conference call, previous prompt and collect information). Any errors associated with performing this operation are returned.
+
+## **II.2.8 Reconnect operation**
+
+### **II.2.8.1 Description**
+
+SCF → SSF
+
+This operation is used to resume a held party to a call (inverse of hold call party connection).
+
+## **II.2.9 Release call party connection operation**
+
+### **II.2.9.1 Consideration**
+
+The difference between this operation and the detach operation needs to be clarified.
+
+### **II.2.9.2 Description**
+
+SCF → SSF
+
+This operation is used to release a call party connection during a call between two or more parties.
+
+## **II.3 Parameters**
+
+The parameters listed in this subclause are additional parameters for the operations itemized in clause 2.
+
+### **II.3.1 Considerations applicable to all parameters in this appendix**
+
+The following parameters are FFS relative to CS-1. These parameters rely on CS-1 capabilities for which the corresponding procedures are undefined. Therefore, they are included in this appendix for completeness.

+## II.5 Procedures
+
+PRINCIPLE is as follows:
+
+The SSF procedures are illustrated by means of Finite State Machines (FSMs).
+
+The (call level) finite state machine, presently described in this Recommendation, consists of several states, which represent different states of the call.
+
+In some of the call states, another level of finite state machine(s) exists, which will have to be described, and which represents the state of a connection to one of the parties. This FSM is named "leg level FSM".
+
+Such a "leg level FSM" is "born out" or "dies out" of some of the call level FSM transitions. Any "event" (e.g. an operation received) causes a state transition of all relevant FSMs.
+
+The Leg states used are the possible values of the parameter "LegStatus", are the following:
+
+- "IDLE": connection to the party does not exist;
+- "PENDING": party not connected, and under creation process;
+- "UNCONNECTED": party not connected, but in a stable state;
+- "CONNECTED": party connected to another party;
+- "INTERACTING": party connected to an SRF.

+## **Q.1220-SERIES INTELLIGENT NETWORK CAPABILITY SET 2 RECOMMENDATION STRUCTURE**
+
+## **Summary**
+
+This Recommendation explains the structure of the Q.122x (CS-2)-series IN Recommendations and provides their outlines.
+
+### **Source**
+
+ITU-T Recommendation Q.1220 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 12th of September 1997.
+
+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation the term *recognized operating agency (ROA)* includes any individual, company, corporation or governmental organization that operates a public correspondence service. The terms *Administration*, *ROA* and *public correspondence* are defined in the *Constitution of the ITU (Geneva, 1992)*.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+
+## **Summary**
+
+Intelligent Network Capability Set 2 (IN CS-2) is the second standardized stage of the Intelligent Network (IN) as an architectural concept for the creation and provision of services, including telecommunication services, service management services and service creation services. This Recommendation gives an introduction to IN CS-2. It describes the main characteristics and overall capabilities of IN CS-2 and defines the service aspects, network aspects and functional relationships that form the basis of the IN CS-2 capabilities.
+
+This Recommendation is the first in the Q.122x-Series of Recommendations devoted to IN CS-2, which builds on the architectural principles of IN as described in the Q.121x- and the Q.120x-Series of Recommendations.
+
+The IN CS-2 Recommendations form a detailed and stable basis for implementing IN CS-2 telecommunication services. They also provide high-level guidelines for supporting service management services, service creation services and some partially supported telecommunication services. The IN CS-2 Recommendations are intended to give the same degree of technical information as the IN CS-1 Recommendations (1995).
+
+## **Source**
+
+ITU-T Recommendation Q.1221 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 12th of September 1997.
+
+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+## 2 Phased standardization
+
+The phased approach of IN capability sets has been described in Recommendation Q.1201.
+
+In order to prepare for the next phases of IN (CS-3 and beyond), the IN CS-2 Recommendations contain both complete technical specifications (with complete support for physical architecture and detailed protocol description) and incomplete specifications that are intended to be the base for subsequent capability sets (with SIB description and the impact on the functional architecture). Capabilities which are only incompletely covered by IN CS-2 Recommendations are highlighted through special notes or caveats.
+
+## 3 General description and scope of IN CS-2
+
+### 3.1 Criteria for IN CS-2
+
+IN CS-2 defines an initial subset of IN capabilities that meet the following general criteria:
+
+- IN CS-2 is a subset of the target Intelligent Network architecture;
+- IN CS-2 is a superset of IN CS-1, as defined in the IN CS-1 Recommendations (1995);
+- IN CS-2 is a set of definitions of capabilities that is of direct use to both manufacturers and network operators;
+- IN CS-2 provides network capabilities defined to support the set of IN CS-2 benchmark services or service features. These capabilities can also be used for the support of other services that may, or may not, be standardized by ITU-T.
+
+The IN CS-2 architecture could be applied for PSTN, ISDN, and mobile networks.
+
+### 3.2 Evolution of IN CS-2
+
+The IN CS-2 Recommendations (Q.122x-Series) form a detailed and stable basis for implementing IN CS-2 telecommunication services. They also give high-level guidelines for supporting service management services and service creation services and some partially supported telecommunication services. Complete technical specifications of these services will be in the subsequent IN capability sets.
+
+As IN CS-1, IN CS-2 takes into account the evolution requirement. It is defined to support the IN CS-2 benchmark services and service features without assumptions that are known to limit its evolution into future capability sets.
+
+The IN CS-2 Recommendations are intended to give the same degree of technical information as the IN CS-1 Recommendations (Q.121x-Series).
+
+## 4 Overview of IN CS-2 Recommendations

+
+## 5 Service aspects
+
+The services and service features that are to be supported by IN CS-2 are fundamental to the IN CS-2 Service-Independent Building Blocks (SIBs), call processing model and service control principles. Three types of services have been identified in IN CS-2: telecommunication service, service management service and service creation services. The last two types of services are first introduced in IN CS-2.
+
+Tables 2 and 3 list IN CS-2 benchmark services and service features, which, in addition to IN CS-1 related telecommunication services/service features, can be used to identify and verify the service-independent capabilities of IN CS-2.
+
+Appendix I provides short prose descriptions of the benchmark services and service features. It was used to develop the current Q.122x-Series of Recommendations and was intended for this purpose only. It is not to be used by service designers for service creation.

+
+### 6.1 Network functions
+
+#### Call control and call unrelated control related functions
+
+SSF – Service switching function: This function interfaces with CCF and SCF. It allows the CCF to be directed by the SCF.
+
+SRF – Specialized resources function: This function provides a category of resources for access by other network entities. Examples of resources include DTMF sending and receiving, protocol conversion, speech recognition, and synthesized speech provision.
+
+CCF – Call control function: This function refers to call and connection handling in the classical sense (e.g. that of an exchange).
+
+CCAF – Call control agent function: This function provides the user access to the network.
+
+CUSF – Call unrelated service function: This function handles call unrelated activities.
+
+SCUAF – Service control user agent function: This function provides the user access to the network call unrelated service function.
+
+#### Service control related functions
+
+SCF – Service control function: This function contains the IN service logic and handles service related processing activity.
+
+SDF – Service data function: This function handles access to service-related data and network data and provides consistency checks on data. It hides from the SCF the real data implementation and provides a logical data view to SCF.
+
+#### Management related functions
+
+SCEF – Service creation environment function: This function allows an intelligent network service to be defined, developed, tested and input to the SMF. The output of this function involves service logic and service data templates.
+
+SMAF – Service management access function: This function provides an interface (e.g. screen presentation) for service subscribers and service administrators who have access to the SMF.
+
+SMF – Service management function: This function involves service operation control, service provision control, service deployment control, service monitoring and billing.
+
+### **6.2 Control architecture principles**
+
+As stated in clause 5 (Service aspects), the service scope of IN CS-2 shall be restricted to single-ended single-point-of-control services. This subclause identifies principles for the control architecture of IN CS-2, in the context of this service scope.
+
+This subclause is organized around three control aspects:
+
+- service invocation and control;
+- end-user interaction with and without the SRF; and
+- service management.
+
+#### **6.2.1 Service invocation and control**
+
+This control aspect involves the CCF, SSF and SCF.
+
+As in IN CS-1, the following points capture key principles for IN CS-2:
+
+- 1) The CCF retains ultimate responsibility for integrity and control of the local connection at all times.
+- 2) The SSF-to-SCF relationship is, by definition, service-independent. Therefore, the CCF and SSF should never contain service logic specific to IN CS-2 supported services.
+- 3) In the event of SCF malfunction, or time-out in the SCF to SSF response, the SSF/CCF combination should be capable of reverting to a default call completion sequence, with appropriate announcement(s) to the calling and/or called party.
+- 4) The SSF should never have to interact with more than one SCF at any given time in order to complete a sequence of query/response interactions on behalf of a calling or called party.
+- 5) Call hand-offs (transfer of responsibility) between SCFs, and between SSFs are permitted in IN CS-2. Nevertheless, the hand-off must be explicit, and must not violate principle 4).
+
+#### **6.2.2 End-user interactions**
+
+As part of the process of formulating a response to the SSF, the SCF may need to enter into a dialogue with the calling or called party. This would take the form of a prompt and collection sequence with the aid of an SRF, or the form of call unrelated/out-channel call related interactions, which are new in IN CS-2 (see 7.2.6 and 7.2.7 for more details).
+
+As in IN CS-1, when the SRF is being used, the SCF in IN CS-2 does not have to enter into this dialogue directly. Instead, it instructs the SRF to carry out a prompt and collection sequence with the calling or called party on its behalf. In general, the actual implementation of IN services will govern the kind of transport systems and protocols (e.g. DTMF, D-channel user-to-user signalling, and data services) used to collect information from the user.
+
+Again, the following key principles apply, when the SRF is being used in IN CS-2:
+
+- 1) The SCF has full IN-supported service control of instruction formulation and sequencing with respect to the SRF and SSF.
+- 2) As a corollary to principle 1), there shall be no direct service control interaction between the SSF and SRF for IN CS-2-based services. The SSF and SRF have a peer-peer relationship for the control of IN CS-2-based services, and both are subsidiary to the SCF.
+
+- 3) The SCF will require the capability of suspending processing of an IN CS-2-based service on behalf of a calling or called party, and then resuming on behalf of the same party at a later time.
+
+#### **6.2.3 Service management**
+
+The control aspects covered in 6.2.1 and 6.2.2 address the real-time interactions between IN CS-2 functions on behalf of a particular calling or called party. In contrast, the service management aspect primarily addresses the network operator's interaction with the SSF, SCF, SDF, and SRF. This interaction normally takes place outside the context of a particular call or service invocation. Nonetheless, IN CS-2 must neither preclude nor constrain the capability of service customers to interact directly with customer-specific service management information (e.g. a personal service profile).
+
+The following points capture key principles for IN CS-2:
+
+- 1) The SMF may be used to add, change or delete IN CS-2-based service-related information or resources in the SSF/CCF, CUSF, SCF, SDF, and SRF. Such changes should not interfere with IN CS-2-based service invocations or calls that are already in progress.
+- 2) The SMAF may be used to add, change, or delete appropriate customer-specific information. The mechanism and safeguards that are put into place by the network operator for this interaction may take advantage of IN CS-2 functions and capabilities.
+- 3) The SCEF may be used by service providers to introduce new services. The task of deploying the service is the role of the SMF and is initiated from within the SMF.
+
+### **6.3 Feature interactions**
+
+As in IN CS-1, the constraints placed on the IN CS-2 architecture have been put in place primarily to minimize and control feature interactions within single domains of responsibility. See 7.2.8 for more details.
+
+The single-endedness of IN CS-2-based services means that all aspects of a call are under the control of one CCF/SSF and one SCF at any point in time [principle 4) in 6.2.1]. The SCF and SSF are therefore responsible for the handling of interactions between IN CS-2-based SSF/CCF capabilities, and non-IN features already provided in the basic network.
+
+### **6.4 Consistency among IN CS-2 supported service features**
+
+The ultimate responsibility for consistency of operations within a set of IN CS-2-based service features lies with the network operator. Nonetheless, the software and data structures of the SCF and SDF, operation and control of these software and database structures via the SMF, and the tools provided by the SCEF, may be designed to aid the network operator in fulfilling this responsibility.
+
+## **7 Functional relationships and interfaces**
+
+### **7.1 Functional relationships and control classes**
+
+Five groups of control capabilities, called control classes, have been identified to support the functional relationships:
+
+- 1) Bearer connection control: the class of capabilities to establish, and clear the bearer connections (e.g. voice paths through the network), and provide surveillance.
+
+- 2) Non-IN call control: the class of capabilities to invoke the user and provide the end-to-end control required for the non-IN delivery of supplementary services. The non-IN delivery does not involve the structured separation of the CCF, SSF, and SCF.
+- 3) IN service-control: the class of capabilities that involve the structured separation of the SSF from SCF.
+- 4) Service management control: the class of capabilities that involve service deployment, service provisioning, service operation control, and service monitoring.
+- 5) Non-IN call unrelated control: the class of capabilities to establish, provide monitoring, and clear a non-bearer connection (e.g. out-channel interaction via the DSS 1 D-channel without a bearer connection).
+
+Figure 2 depicts the classes of control capabilities required for the functional relationships. The following subsections further describe the control relationships for each control class, respectively. A control relationship is the relationship between a functional relationship and a control class.
+
+![Diagram showing functional relationships and control classes for IN CS-2. It includes nodes for SMF, SRF, SCUAF, CCAF, CUSF, CCF, SSF, SCF, SDF, SMAF, and SCEF. A legend defines five types of control relationships: Bearer connection control relationship (dotted line), Non-IN call control (dash-dot line), Non-IN call unrelated control (double line), IN service control relationship to be standardized for CS-2 (dashed line), and Service management control relationship (long dash-dot-dot line).](2cde062fd82833415971a8bd1a2cafab_img.jpg)
+
+The diagram illustrates the functional relationships and control classes for IN CS-2. It features several network function nodes represented by ovals: SMF (Service Management Function), SRF (Service Resource Function), SCUAF (Service Control User Agent Function), CCAF (Call Control User Agent Function), CUSF (Call User Service Function), CCF (Call Control Function), SSF (Service Switching Function), SCF (Service Control Function), SDF (Service Data Function), SMAF (Service Management Agent Function), and SCEF (Service Control Element Function). The nodes are arranged in a hierarchical manner, with SMF at the top, connected to various other nodes. A legend at the bottom left defines the line styles used for different control relationships:
+ 
+
+- Bearer connection control relationship:** Represented by a dotted line.
+- Non-IN call control:** Represented by a dash-dot line.
+- Non-IN call unrelated control:** Represented by a double line.
+- IN service control relationship to be standardized for CS-2:** Represented by a dashed line.
+- Service management control relationship:** Represented by a long dash-dot-dot line.
+
+ Functional relationships are shown as solid lines between nodes. For example, SMF is connected to SRF, SCUAF, CCAF, CUSF, CCF, SSF, and SCF. SCF is connected to SDF, SSF, and CCF. CCF is connected to CCAF and another CCF node. The diagram also includes a note "All other network functions except CCAF" pointing to the SMF node and a reference code "T1184900-97" in the bottom right corner.

+
+**Figure 2/Q.1221 – Functional relationships and control classes for IN CS-2**
+
+#### 7.1.1 Bearer connection control
+
+Control relationships exist between the bearer connection control class and the CCAF-CCF, CCF-CCF, and CCF-SRF functional relationships, respectively. Standard interfaces are employed to realize these control relationships and are listed below by the involved functional relationships:
+
+- CCAF-CCF: DSS 1/Q.931
+- CCF-CCF: SS7/ISUP
+- CCF-SRF: DSS 1/Q.931; SS7/ISUP
+
+#### 7.1.2 Non-IN call control
+
+Control relationships exist between the non-IN call control class and the CCAF-CCF, CCF-CCF, and CCF-SRF functional relationships, respectively. Standard interfaces are employed to realize these control relationships and are listed below by the involved functional relationships:
+
+- CCAF-CCF: DSS 1/Q.931
+- CCF-CCF: SS7/ISUP
+- CCF-SRF: DSS 1/Q.931; SS7/ISUP
+
+#### 7.1.3 IN service control
+
+Control relationships exist between the IN service control class and the SCF-CUSF, SCF-SCF, SCF-SDF, SCF-SRF, SCF-SSF, and SDF-SDF functional relationships, respectively. They can be realized through SS7/TCAP/INAP.
+
+IN CS-2 can support mid-call and topology manipulation capabilities, as noted in other Q.122x-Series of Recommendations. In addition, IN CS-2 may support services or service features which require ISUP or/and DSS 1 modifications.
+
+#### 7.1.4 Service management control
+
+Control relationships exist between the service management control class and the SMF-CUSF, SMF-SCF, SMF-SCEF, SMF-SDF, SMF-SMAF, SMF-SRF, and SMF-SSF functional relationships, respectively. They can be realized through CMIP/Q.812. No modification to INAP (i.e. Q.1228) is foreseen for management aspects. In addition, no modification to the IN physical plane (i.e. Q.1225) is foreseen; namely, no additional Physical Entities (PEs) are required assuming basic PEs exist for management aspects.
+
+#### 7.1.5 Non-IN call unrelated control
+
+There is a control relationships between the non-IN call unrelated control class and the SCUAf-CUSF functional relationship. Standard interfaces listed below are employed to realize this control relationship:
+
+- SCUAf-CUSF: DSS 1/Q.932; SS7/ISUP
+
+### 7.2 Key functions and interfaces
+
+#### 7.2.1 Single point multiple points of control
+
+Single point of control describes a control relationship where the same aspects of a call are influenced by one and only one service control function at any point in time. Multiple points of control is the ability for multiple service logic instances to interact with a single call segment. The SSF/CCF may have to be able to manage interactions between IN service logic instances realized in different service logic instances that are simultaneously active on a single call. New capabilities beyond the single point of control capability are required to enable the SCF to control two call segments in different SSF/CCFs simultaneously.
+
+*Interfaces:* SCF-SSF/CCF, SCF-SCF
+
+#### 7.2.2 Single-ended/multi-ended calls
+
+A single-ended service feature applies to one and only one party in a call and is orthogonal (independent) at both the service and topology levels to any other parties participating in the call. Orthogonality allows another instance of the same or a different single-ended service feature to apply to another party in the same call as long as the service feature instances do not have feature interaction problems with each other.
+
+Multi-ended is the ability for a service logic instance to interact with multiple call segments. The service logic instance may have to be able to manage IN call/connection processing among multiple call segments on a single call.
+
+*Interfaces:* SCF-SSF/CCF, SSF-SSF, SCF-SCF
+
+#### **7.2.3 Mid-call interruption**
+
+Mid-call interruption supports SCF-SSF interaction during the alerting or active phase of a call (i.e. during ringing for the originating party or after the call reaching a stable state).
+
+*Interfaces:* SCF-SSF/CCF.
+
+#### **7.2.4 Call party handling**
+
+Call party handling is the ability to manage various parties' participation in a call. Parties' bearer channels may be added, deleted, joined and/or separated from the other parties involved in the call.
+
+*Interfaces:* SCF-SSF/CCF.
+
+#### **7.2.5 Enhanced SRF**
+
+Enhanced SRF capabilities are identified in 4.3.4/Q.1214 and 3.3.6/Q.1224. Examples include audio conference bridge, information distribution bridge, text-to-speech synthesis, protocol converters, automatic voice recognition and voice message sender/receiver. Capabilities such as voice message sender/receiver, text to speech synthesis, and automatic voice recognition can be supported using elementary operations (as in IN CS-1) or user interaction scripts (as in IN CS-2). The latter is based on the concept of task sharing between SCF and SRF; the SCF is responsible for the global service logic while the SRF is responsible for the user interaction logic. Other capabilities such as audioconference bridge and information distribution bridge are supported by using the hybrid approach for call party handling that an SRF as well as an SSF is involved in providing the services.
+
+*Interfaces:* SRF-SCF, SSF-SCF.
+
+#### **7.2.6 Call unrelated user interaction**
+
+Call unrelated user interaction between the user and service processing is the ability to communicate information outside the context of a call, required for services/service features such as message waiting indication. As this capability is not supported by the BCSM, which is call related, the basic call unrelated state model (BCUSM) is introduced in IN CS-2.
+
+*Interfaces:* SCF-CUSF, CUSF-SCUAF.
+
+#### **7.2.7 Out-channel call related user interaction**
+
+Out-channel call related user interaction provides the ability to communicate information within the context of a call on the out-channel signalling access (within the same call reference of a call) to support features such as user authentication.
+
+*Interfaces:* SCF-SSF/CCF, SCF-SRF.
+
+#### **7.2.8 Service/feature interaction (service processing)**
+
+Service interaction during service processing focuses on the service interaction in the phase of service executions. It relates to the call control. To help characterize service interactions between non-IN supported services/features and IN supported services/features, it may be useful to map non-IN supported services/features to the IN-Switching State Model (IN-SSM). Non-IN supported services/features may be fully mapped, partially mapped, or unmapped. Placement of a non-IN supported service or service feature into one of these groups serves to characterize the information available to the Feature Interaction Manager/Call Manager (FIM/CM) during the operation of the feature. In characterizing service interactions for fully mapped non-IN-based services and service features, higher priority should be given to fully mapped non-IN-based services than to partially or unmapped non-IN-based services.
+
+*Interfaces:* SCF-SCF, SCF-SDF, SCF-SRF, SCF-SSF/CCF
+
+#### 7.2.9 Internetworking
+
+Internetworking is the process in which several networks (potentially of different types, such as IN-structured, non-IN-structured, public and private) cooperate to provide a service. The need for internetworking capabilities results from the fact that customers may want to access services which span multiple networks. A typical situation is when the data needed by a service (e.g. UPT, VPN and global network services) reside in a network that is different from the one in which the call has originated.
+
+To meet the IN CS-2 internetworking need, extension of the IN models and architecture to a multi-network context as well as extension of existing functionalities defined in IN CS-1 to support interfaces between functional elements physically located in different network contexts has been provided by IN CS-2.
+
+IN CS-2 identifies the SCF-SCF, SCF-SDF, SCF-IAF, SDF-SDF and SMF-SMF relationships for internetworking purposes. Distributed service logic, but not distributed service control, is supported. Additionally, internetwork management interactions and distributed data handling processes are supported.
+
+##### 7.2.9.1 Internetworking between IN-structured networks
+
+General requirements for internetworking capabilities are presented in 2.2.6/Q.1201.
+
+Although the involved networks may have different access types (e.g. PSTN and ISDN), as well as different levels of IN structure, IN CS-2 internetworking services are to be provided to customers in a consistent way, regardless of such differences.
+
+Similar to Figure 1, which depicts the functional relationships between the IN functions within one network, Figure 3 depicts possible functional relationships between the IN functions that are located in two different networks.
+
+The following observations can be made concerning the applicability of Figure 3 to IN CS-2:
+
+![Diagram showing possible IN network interworking functional relationships between Network A and Network B. A vertical dashed line separates the two networks. In Network A, four functional elements are shown in a vertical stack: SMF, SDF, SCF, and SSF. In Network B, the same four functional elements are shown in a vertical stack.

+
+**Figure 3/Q.1221 – Possible IN network interworking functional relationships**
+
+- 1) The SSF-SCF functional relationship across two networks is out of the scope of IN CS-2. As for IN CS-1, and as described in 2.2.6/Q.1201, which underlines the necessity to maintain the network security and network integrity, internetworking between the SSF in one network and the SCF in another one is not an IN CS-2 requirement.
+
+- 2) IN CS-2 will support the SCF-SCF functional relationship across two networks when only one SCF directly interacts with the call. This restriction is necessary because IN CS-2 has no requirement for multiple point of control capability, where two SCFs are able to interact with the call at the same time. This internetworking relationship is new for IN CS-2 as it was not supported by IN CS-1.
+- 3) As in IN CS-1, the SCF-SDF functional relationship across two networks is within the scope of IN CS-2.
+- 4) The SDF-SDF functional relationship across two networks is within the scope of IN CS-2. This internetworking relationship is new for IN CS-2 as it was not supported by IN CS-1.
+- 5) The SMF-SMF functional relationship across two networks is within the scope of IN CS-2. The assumed protocol should align with TMN generic protocols and the TMN X interface. This internetworking relationship is new for IN CS-2 as it was not supported by IN CS-1.
+- 6) In IN CS-2, specific internetworking capabilities are assumed to be localized within the FEs which support an internetworking relationship, i.e. within the SCF, SDF and the SMF.
+- 7) The internal architecture of one network is not visible from another network. However, functions needed for processing internetworking are to be visible from the other network (IN or non-IN).
+
+##### 7.2.9.2 Internetworking with non-IN-structured networks
+
+The previous subclause defines the internetworking relationships for two networks, both of which have a structure compatible with the IN functional architecture. For IN CS-2, the Intelligent Access Function (IAF) provides access between the SCF of an IN-structured network and an entity of a non IN-structured network. This latter entity may be other networks or customers (e.g. private networks, simple databases used in the customer call routing service, terminals, and PABXs). It:
+
+- a) provides access to and from the SCF of the IN-structured network; and
+- b) maps the information between the internal and external representation.
+
+As such, for the subscriber's each incoming call, information (such as dialled number, calling number, and caller entered digits) may be conveyed, for example, from a public network to a private one for the latter to determine how that call will be handled. A private network is defined as a network which provides services only to a specific set of users.
+
+Similar to Figure 3, which depicts possible functional relationships between the IN functions that are located in two different IN-structured networks, Figure 4 depicts a possible functional relationship between the SCF located in an IN-structured network and the IAF located in a non-IN-structured network.
+
+![Diagram showing the functional relationship between an SCF in Network A (IN-structured network) and an IAF in Network B (non-IN-structured network).](4cc7cdce3d498d8b0ba033a9be24ade5_img.jpg)
+
+The diagram illustrates a functional relationship between two networks, Network A and Network B, separated by a vertical dashed line. Network A is labeled 'IN-structured network' and contains an oval labeled 'SCF'. Network B is labeled 'non-IN-structured network' and contains an oval labeled 'IAF'. A solid horizontal line connects the 'SCF' oval in Network A to the 'IAF' oval in Network B, crossing the dashed boundary line. Below the 'IAF' oval, the text 'T1184920-97' is present.

+
+#### 7.2.10 Security
+
+Security is a general property which relates to safe and reliable operation. The high-level requirements of a secure system are:
+
+- Confidentiality, which is defined in Recommendation X.800 as *the avoidance of the disclosure of information without the permission of its owner*. Thus, confidentiality may be considered as a property which ensures that conversations or interactions remain private;
+- Integrity, which is defined in Recommendation X.800 as *the property that data has not been altered or destroyed in an unauthorized manner*. Integrity may then be considered as a property which ensures that operations occur as they are expected to;
+- Availability, which may be considered as a property relating to the readiness of resources for authorized use;
+- Accountability, which may be considered as a property which ensures that any operational request can be correctly attributed in case of doubt or dispute.
+
+The components of an IN system must be assembled and operated in such a way as to provide a defined level of security.
+
+To assist in this, any interface within the IN functional architecture may have the need to apply security assisting functions to the information flows passing across the interface such as:
+
+- Network access security functions: This includes user/terminal authentication (i.e. the result of a process by which a service user proves his or her identity to an IN system), user profile verification (i.e. the verification that a user is authorized to use a functionality);
+- Internetworking security functions: This includes peer entity authentication (i.e. a process which allows a communicating entity to prove its identity to another entity in the network), signalling data or TMN data integrity, non-repudiation, confidentiality, entity profile verification (i.e. the verification that an entity is authorized to use a functionality).
+
+Recommendation Q.1228 defines a generic set of security mechanisms and procedures to offer some of the generic properties described above. In any particular circumstance, a set of network elements will be required to be configured according to some security scheme.
+
+The definition of IN CS-2 offers the provision of certain security assisting functions at the SCF-SDF, SDF-SDF, and SCF-SCF interfaces. Additional security functions may be required depending on the security schemes in place.
+
+*Interfaces:* SCF-SCF, SCF-SDF, SDF-SDF
+
+#### 7.2.11 IN-TMN
+
+Applying TMN concepts, TMN functional architecture modeling aspects to the IN are identified in Recommendation Q.1224 and its associated annexes. Harmonization of IN/TMN using TMN concepts to define service management and network management is specified in 7.2.12.
+
+*Interfaces:* See 7.2.12.
+
+#### 7.2.12 Service management
+
+IN specific service management refers to the network capabilities that are necessary from a network operator's point of view, to support the proper operation of services. This includes management during deployment, provisioning and utilization phases. TMN functionality can be used to provide these capabilities. Service interaction during service management focuses on service interaction in the phase of service subscription, service registration and service activation.
+
+The Service Management Function (SMF) is defined in 2.4/Q.1204. The actors who have access to the SMAF and thereby the SMF are service subscribers and service administrators. Service subscribers are users of the IN-supported services. (When subscribing for a particular IN-supported service, the service subscribers may choose some service features offered by the service provider
+
+according to their needs.) Service administrators consist of both the service provider and network provider; they are responsible for the following areas of service support:
+
+- 1) Service provisioning: introduction and allocation of the service logic with the ability to modify that service logic. Provisioning may also include changing certain service-related parameters prior to and during testing and distributing the related logic and data to other IN functional entities;
+- 2) Service monitoring: monitoring service performance, receive trouble reports from service subscribers, and using the SMF to identify and correct the problem;
+- 3) Security management: secure access to the functions of the SMAF.
+
+The above activities so far have been performed only by service administrators; however, service subscribers need and demand more control over the specifics of the services. The capabilities of the service subscribers to control the subscribed services are named "customer control service capability". Specific controlling capabilities can be granted depending on specific services (e.g. the freephone-related capabilities may differ from the VPN-related capabilities).
+
+In general, this set of capabilities would allow service subscribers to:
+
+- 1) view and adjust the service parameters they subscribe to; and
+- 2) request and receive reports.
+
+Two technical approaches are supported in IN for the provision of the customer control service capability:
+
+- 1) Access through the SMAF to the SDF: This would be done via dedicated terminals.
+- 2) Access through the network via the CCAF: This approach is supported at service processing level, and the SDF is involved.
+
+The second solution is constrained technically by the network-to-user interface and by the data available in the SDF. Full customer control service capability is only possible with the first solution.
+
+The solution choice is specific to each service. For instance, simple customer control service capability, such as location registration in UPT from any terminal, would be based on the second solution. A more complex customer control service capability, such as VPN management would be based on the first solution.
+
+The management-related functional relationships (i.e. SMF-SCF, SMF-SDF, SMF-SSF/CCF, SMF-SRF, and SMF-CUSF) are defined in IN CS-2 down to the distributed functional plane, with a high-level description of functions, functional model, functional relationships and interfaces (and guidance on the information model). The technical assumption is the alignment of IN and TMN. The assumed protocols to be used are the TMN generic protocols (e.g. common management information protocol, CMIP, as defined in Recommendation Q.812). No modification to INAP (Recommendation Q.1228) are foreseen for management aspects.
+
+Within IN CS-2, the management relationships to be studied are: SMF-SCEF, SMF-SMAF, SMF-SSF/CCF, SMF-SCF, SMF-SDF, and SMF-SRF. The last four relationships describe the management of IN network elements.
+
+The IN-specific management requirements concerning the service life cycle phases of creation, deployment, provisioning and utilization of IN-supported services are considered from a service plane point of view. Listed below are the requirements at the service and network level.
+
+The service level requirements are:
+
+- Install and configure the service script/software.
+

+- Handle complaints on service malfunctioning.
+- Handle customer control requests (e.g. update customized announcements and change parameter settings).
+- Remove customer data from the network.
+- Obtain information on the usage of the service per service subscriber for billing (e.g. via usage records).
+
+The network level requirements are:
+
+- Test the installed software.
+- Install and configure trigger data.
+- Install and configure signalling routing data.
+- Install and configure network elements.
+- Configure the workstation program.
+- Monitor and control the performance/QOS of the network element.

+
+#### 7.2.13 Service creation
+
+IN service creation presents the operator's point of view for the creation of new services. These include service specification, service development, and service verification. Output is expected to be service logic for the execution aspects of a service, service logic for the management aspects of a service, and user data related logic and service data related logic. This includes partitioning of functionality between the SMF and SCEF.
+
+The SCEF allows services provided in Intelligent Network to be defined, developed, tested and input to SMF. Output of this function would include service logic, service management logic, service data template and service trigger information. Based on this definition, it is possible to distinguish the following three phases of service creation activity (defined in 2.2.2/1201):
+
+- service specification;
+- service development;
+- service verification.
+
+The service specification phase involves the following:
+
+- requirements specification based on customer/market input;
+- analysis;
+- feature interaction rules;
+- OAM requirements;
+- high-level design including evolution aspects.
+
+The service development phase involves the following:
+
+- detailed design:
+  - feature design;
+  - data schema;
+  - test case generation;
+  - engineering considerations;
+- service logic and service management logic definition;
+- development of service logic modules.
+
+Note that the feature design may impact platform development but it should not be considered as part of the service creation services because the impact on the platform depends on the intrinsic
+
+capabilities of the platform and it is vendor dependent. The output of the service development phase feeds into service verification phase.
+
+The service verification phase involves the following:
+
+- service logic syntactic checking;
+- service logic and service management logic simulation;
+- service logic module verification;
+- network simulation;
+- testing for service order requirement;
+- engineering verification.
+
+Service interaction focuses on service interaction in all phases of service creation. The output of this phase verifies that customer/market requirements are met.
+
+Similarly, the SMF functionality can be subdivided into following phases:
+
+- service deployment;
+- service provisioning;
+- monitoring and maintenance;
+- service negotiation.
+
+The service deployment phase involves the following:
+
+- service configuration on each Functionality Entity (FE), i.e. SCF, SSF, SDF, and SRF;
+- configuration verification;
+- subscription template and customization;
+- database initialization;
+- resource allocation on each FE;
+- distribution of service support data and logic on each FE;
+- service activation and deactivation via trigger detection point data distribution.
+
+Service interaction (from a service creation perspective) focuses on service interaction in the service deployment phase.
+
+The service distribution activity involves transferring appropriate information about the service to other FEs, e.g. SCF, SDF, SSF, SRF.
+
+The service provisioning phase involves the following activities:
+
+- customer subscription data-fill based on service order template and service customization;
+- validation, taking into account customer account information via SMAF;
+- subscription provisioning, i.e. informing the subscriber that his order has been executed.
+
+The service monitoring and maintenance phase involves the following activities:
+
+- audit;
+- operations measurement/log collection:
+  - logic tracing;
+  - fraud detection;
+  - traffic management;
+  - usage report;
+  - performance analysis.
+
+The service negotiation phase of the SMF is needed to ensure that there are sufficient network resources available to support the customer's request for IN supported services. This would include at least the following verifications:
+
+- Ensure that the customer has access to the Service Switching Function (SSF).
+- Ensure that the SSF/CCF supports the requested IN supported service.
+- Ensure that all IN resources are available to support the requested IN supported service.
+- Ensure that the requested IN supported service does not conflict with other existing IN supported services that the customer currently subscribes to. This requires an evaluation of potential feature interactions.
+- Ensure that the customer has access to other switch-based services, such as ISDN, that may be required by the requested IN supported service.
+- Ensure that the requested IN supported service does not conflict with existing switch-based services that the customer currently subscribes to.
+
+Service interaction during service creation focuses on the service interaction in the phase of service creation and service deployment.
+
+This provides a preliminary analysis of the SCEF and SMF functionalities.
+
+Once the functional partitioning between SMF and SCEF are established, then specific functions pertaining to what an SCEF is expected to provide can be addressed in greater detail. An SCEF is unlike other network elements in that it is a tool, not a service execution platform. The implementation of a service design tool, including the extent of the functions is offered its end-user, should be independent of network configurations, i.e. platforms. It is proposed that the services be identified to reflect what information is required between the SCEF and the service management element. With respect to standardization of service creation, it is the interface to other network elements that should be seen as the focal concern. In particular, the SCEF to SMF interface should be specified.

+#### 7.2.14 Personal mobility
+
+Personal mobility allows a user to associate with and/or configure any terminal, according to individual needs to access telecommunication services. It also enables the user to customize various aspects of the offered features, thereby receiving personal telecommunication service features. Universal Personal Telecommunications (UPT) is an example of a telecommunications service supporting personal mobility.
+
+IN CS-2 provides the network capabilities that are necessary to support personal mobility among heterogeneous access networks. In particular, IN CS-2 has extended the IN model and architecture to guarantee a correct handling of the user profile and service processing, independent of the user
+
+access. The IN CS-2 relationships that may be involved in providing personal mobility services include the SCF-SDF, SDF-SDF, SCF-SCF and SCF-SSF.
+
+# APPENDIX I
+
+## IN CS-2 benchmark services and features
+
+## I.1 General
+
+This Appendix provides short prose descriptions of the benchmark services and service features used to develop the current Q.122x-Series of Recommendations. These descriptions are not meant to be used by service designers for service creation. Note that some of the listed services and service features may be partially supported by IN CS-2 and not be supported at the protocol level.
+
+## I.2 Definitions
+
+The following definitions have to be taken into consideration:
+
+### I.2.1 Telecommunication services
+
+A telecommunication service is an information telecommunication service offered to subscribers by a service provider in areas where the (IN supported) service logic is executed to provide the service. A subscriber is a person or organization that is billed for use of a telecommunication service. A subscription is an instance of telecommunication service that is provided and billed to a particular subscriber.
+
+### I.2.2 Service management services
+
+A service management service offers customization, control and monitoring functions to the telecommunication services for which it is provided. This may be a commercial offering to subscribers.
+
+### I.2.3 Service creation services
+
+A service creation service offers specification, development, verification functions to the network operator.
+
+## I.3 Telecommunication services
+
+### I.3.1 General
+
+It should be recognized that the services proposed are not an extensive list but are taken from categories of services that are important for the next phase of IN standardization. Work to enable this proposed set of services and service features will also enable other services that would also use these capabilities.
+
+### I.3.2 Definitions
+
+More detailed definitions are to be found in Recommendation Q.1222.
+
+**I.3.2.1** A **telecommunication service** is characterized by one or more core service features, that can be optionally enhanced by other service features.
+
+**I.3.2.2** A **service feature** is a specific aspect of a telecommunication service that can also be used in conjunction with other telecommunication services/service features. A **core service feature** is a particular service feature fundamental to the telecommunication service, i.e. in the absence of this
+
+service feature, the name of the telecommunication service does not make sense as a commercial offering to the service subscriber.
+
+### **I.3.3 Mobility service features (UPT, FPLMTS)**
+
+These service features are aimed at, but not limited to, supporting UPT and FPLMTS. Other telecommunication services may utilize these service features.
+
+#### **I.3.3.1 Personal mobility features (UPT)**
+
+Personal mobility allows a user to appear at any network access point and initiate telecommunication services. Once recognized, the end user can access provisioned services and features according to a personal user profile, which can be customized by the subscriber or user. Please note that service features used in UPT but of more general nature (such as service indication, internetwork service profile interrogation, modification or transfer, reset of UPT registration for incoming calls) are described in 3.5.
+
+**I.3.3.1.1 User authentication (UAUT):** This feature confirms the identity of a user with the network and the identity of the network with a user. UAUT takes place during interactions between the network and a user.
+
+UAUT assumes that appropriate information is exchanged between the network and a user. A user has to provide his authentication data through the terminal or via an access device, which transmits the data to the network as well as establish a connection between the network and a user.
+
+UAUT implies the use of security algorithms to check the validity of the information provided by a user.
+
+Once the authentication has been performed, the visited network might keep the track of the authenticated user to avoid multiple use of UAUT.
+
+**I.3.3.1.2 User registration (UREG):** This feature enables a user to register on a terminal access for the purpose of receiving or placing calls. This may be accomplished either from the terminal where the user wishes to register or from another terminal (remote registration) There are two aspects to this feature, which are both included in the list of UPT Set 1 features described in the Recommendation F.851 "UPT – Service description".
+
+**I.3.3.1.2.1 in-call registration** is a means by which a user registers from the current terminal address for incoming calls to be presented to that terminal address. When registered, all the incoming calls to that user will be presented to the registered terminal for the duration specified by the user, or until a specific de-registration time. A new in-call registration made by the same user will cancel the previous in-call registration of that user. Several users may register for incoming calls to the same terminal address simultaneously. A user may also explicitly de-register for incoming calls.
+
+**I.3.3.1.2.2 Outgoing call registration (OGREG):** The out-call registration allows a user from the current terminal address to register for outgoing calls to be made from that terminal address. When registered, all outgoing calls (except some calls like emergency calls) from the terminal address will be charged to the user account for the duration specified by the user in terms of time or number of calls, or until a de-registration takes place. Normally the user will not have to carry out any further authentication procedures in order to make outgoing calls. However, optionally a simplified authentication procedure may be used. A user may be registered for outgoing calls at several terminal addresses simultaneously, but at any time only one user may be registered for outgoing calls at the same terminal address. The user may prevent another user from de-registering him for outgoing calls. The user may also explicitly de-register for outgoing calls. A third party *may* prevent a user from registering at his terminal address for outgoing calls.
+
+**I.3.3.1.3 Secure answering (SANSW):** Secure answering is a feature by which the service subscriber/user requires that incoming calls cannot be answered unless the answering party first successfully authenticates himself as the wanted subscriber. The use of this feature is strictly related to the privacy requirements from a service subscriber/user; although it has been considered only in the UPT description, it could be useful also for other services, e.g. freephone, VPN, and UMTS. (This feature is currently included in the list of UPT Set 1 optional features in Recommendation F.851 "UPT – Service description", with the name "called party specific secure answering of incoming UPT calls").
+
+**I.3.3.1.4 Follow-on (FO):** This feature enables a user to make a series of service requests without going through the identification and authentication process before each service feature request. The identification and authentication are performed only for the first service request of the series. The user should be offered the choice after each service feature request to continue with a new service request.
+
+**I.3.3.1.5 Flexible (call) origination authorization (FOA):** The FOA feature can take effect immediately prior to the time that an IN capable switch would authorize call origination, during the call set-up process. A customized algorithm, provided by the network provider or the subscriber, can then determine whether or not the call should be originated.
+
+If the call is not authorized by the IN customized algorithm, then the call attempt is ended. If the call is authorized by the IN customized algorithm, then, depending on the feature subscriber profile, call processing can bypass switch-based authorization, or call processing can continue with switch-based authorization.
+
+The FOA feature can be used by personal and terminal mobility services to provide authorization capability where a switch has restrictions on call origination authorization. Such restrictions could be a consequence of a switched-based call screening feature, on behalf of the "home" subscriber of a given access line. There exists the possibility that a mobile user may roam to such an access line, at which time restrictions may have to be removed.
+
+**I.3.3.1.6 Flexible (call) termination authorization (FTA):** The FTA feature can take effect immediately prior to the time that an IN capable switch would authorize call termination, during the call set-up process. A customized algorithm, provided by the network provider or the subscriber, can then determine whether or not the call should be authorized.
+
+If the call is not authorized by the IN customized algorithm, then the call attempt is ended. If the call is authorized by the IN customized algorithm, then, depending on the feature subscriber profile, call processing can bypass switched-based authorization, or call processing can continue with switch-based authorization.
+
+The FTA feature can be used by personal and terminal mobility services to provide authorization capability where a switch has restrictions on call termination authorization. Such restrictions could be a consequence of a switched-based call screening feature, on behalf of the "home" subscriber of a given access line. There exists the possibility that a mobile user may roam to such an access line, at which time restrictions may have to be removed.
+
+**I.3.3.1.7 Provision of stored messages (PSM):** When the service subscriber registers the location, the network automatically informs the subscriber of the service and sends the voice messages which were stored before.
+
+**I.3.3.1.8 Multiple terminal address registration (MTAR):** This service feature enables a user to be registered for incoming calls on more than one terminal, with calls being offered to the terminals according to a certain algorithm (e.g. in sequence if there is no answer after a user-determined time (i.e. a user-configurable hunt group), and simultaneously).
+
+**I.3.3.1.9 Intended recipient identity presentation (IRIP):** This service feature allows identification at the receiving terminal of the intended recipient of an incoming call. It is required to enable Secure Answering (SANSW) to be offered when there is more than one UPT user registered for incoming calls on the one terminal.
+
+**I.3.3.1.10 Blocking/unblocking of incoming calls (BUIC):** This service feature enables any person, even if not a UPT user, to block and unblock calls incoming to UPT users currently registered on the third party's terminal.
+
+#### **I.3.3.2 Terminal mobility features (FPLMTS)**
+
+Terminal mobility provides a tetherless link between the user's terminal equipment and fixed network access points, thereby providing freedom of movement for the user during the use of telecommunication services and service features. The network is able to locate and identify a particular terminal as it appears within a network domain and while it is in motion, whether or not a call is currently taking place. Please note that service features used in FPLMTS but of more general nature (such as internetwork service profile interrogation, modification or transfer, mobile call origination or mobile user call termination) are described in 3.5.
+
+**I.3.3.2.1 Terminal authentication (TAUT):** The TAUT feature is initiated within the mobility processes of location management (i.e. terminal location registration), call origination, call delivery and at other times as initiated by the network or terminal. In support of security, the feature ensures the validity of the terminal and the network. Also, the feature enables the establishment of a private control and communications channel between the network and a terminal. Authentication process should occur when a terminal authenticates either in its home network or visited network.
+
+**I.3.3.2.2 Handover (HOV):** The handover (HOV) service feature enables a mobile terminal to change network access areas/points within a network or to an other network, while maintaining the call(s) and/or signalling relationship(s). Active services should be maintained, within the limits imposed by available radio and network resources. In the case of a lack of resources, active services could be modified (e.g. fall back to a lower grade of service quality) or interrupted.
+
+Handover is a complex operation involving four types of entities. They are: the monitoring entity type, the initiating entity type, the performing entity type and the controlling entity type. There could be more than one entity of the same type involved in the handover operation, even during the same handover. Handover can be initiated by the terminal, or network entities.
+
+The handover service feature consists of four processes: the handover monitoring process, the handover decision process, the handover execution process and the handover completion process.
+
+**Monitoring process:** This process collects radio measurements, aggregates these data (e.g. averaging) and forwards them to the initiating entity. These data are to be used as indicators of the quality of the radio link and of the radio environment (e.g. signal profile and path loss) and also for determining the target cell during the decision process.
+
+**Decision process:** The decision process comprises two sub-processes which can take place simultaneously. The first one determines when a handover must be triggered by comparing the data from the monitoring process with preset thresholds. The second one selects the target cell according to criteria defined for the handover. Otherwise stated, the decision process uses two sets of criteria: one for the triggering decision and the other for the selection of the target cell.
+
+**Execution process:** The execution process reserves and allocates the resources and creates the new link and routes the traffic and the signalling of the handed-over communication on this new link. This process could include a macro diversity phase during which two links (the old and the new one) are both in use.
+
+NOTE – The interrelationship between the resource reservation and the execution is not clear enough at this stage. Defining any precedence between the resource reservation and the execution operations in the network could impact on the handover processes at the radio interface. The way by which resource reservation at the radio interface and in the network are linked together for handover execution should be investigated. There is a need to consider the resource reservation process as an underlying process of the execution process.
+
+**Completion process:** This process frees up any unused resources.
+
+**I.3.3.2.3 Terminal location registration (TLR):** Terminal location registration is used when terminals notify the system of their location. This is a feature by which the location area information of a terminal is registered with the network. A location registration procedure is generally carried out (A) when the terminal changes the location area, or (B) when no previous location details are known (including updating of the location area information after network or terminal failure).
+
+The location area information is used by the network to handle incoming calls to the terminal. Terminal location registration uses the terminal authentication service feature to validate the terminal. Case (B) also covers the situation when a terminal first appears in a network. The terminal location registration may be accompanied by the internetwork service profile transfer feature.
+
+**I.3.3.2.4 Terminal attach/detach (ATDT):** The detach feature is used by the terminal to notify the network whether the terminal is temporarily not reachable. The network will modify the status information of the terminal.
+
+The attach feature is used by the terminal to notify the network whether the terminal is reachable again. The network will modify the status information of the terminal.
+
+**I.3.3.2.5 Terminal paging (TPAG):** This service feature enables the determination of the current location of a user or of a mobile terminal. It pages the terminal in the terminal location registration area based on the stored terminal location information, and determines the visited cell by the response from the terminal.
+
+When several cells exist in a terminal location registration area, the following paging procedures may be used:
+
+- 1) paging to all the cells in the terminal location registration area simultaneously;
+- 2) paging to some of the cells in turn based on, e.g. priority and traffic statistics.
+
+Different location registration area for macro, micro and pico cells can be overlaid at some locations within the service area. TPAG can be invoked by the network other than the network in which the terminal resides. Paging is executed in the network which covers the location area registered by mobile terminals. It can be executed before incoming calls are routed to the network (i.e. other network can invoke the paging execution to get the routing information).
+
+**I.3.3.2.6 Radio paging (RPAG):** This service feature enables one-way personal selective calling with alert. The RPAG feature enables a user to send a message, either voice, tone, or alphanumeric, to a selected pager terminal or a group of terminals. This service feature also enables a user to request a receipt for such a message.
+
+The length of both the sending message and reply message will be limited. The sending messages will not be sent on a real-time basis. The waiting duration for a reply message will also be limited. A sending user will send a message to a service centre. The service centre will then send the message through radio channels. For a message without reply receipt requested, the service centre may send the message again at a pre-determined time spacing to ensure reception. For a message requesting reply receipt, the service centre /paging control node will wait for a pre-determined time interval for a reply message, and send it again if no reply message is received. It will repeat this process till a maximum number of tries is reached. The reply message may be generated automatically by the pager terminal. It may also be generated by the paged user within a limited short time interval
+
+(e.g. 30 seconds) after the message is received or the pager terminal will generate the reply message automatically. The service centre will store the reply message with a time-stamp for sender's retrieval. It should be clear that this service feature allows two-way message exchange, but not on a real-time basis, between a sender and a receiver.
+
+**I.3.3.2.7 Emergency calls in wireless (ECW):** The ECW service feature allows emergency calls to have priority over all other calls to ensure service. Emergency calls can be readily connected without dropping other active calls and without the requirement of successful terminal authentication, privacy or user authentication. Some services restrictions which may apply to the terminal may be suspended (e.g. time-of-day restrictions). Once active, the emergency call has priority over other active calls (e.g. during handover). The ECW service feature consists of three processes.
+
+**The emergency call origination process:** This process initiates a call with conventional terminal authentication, privacy, user authentication and user validation being performed. However, it does not depend on the success of these processes. The purpose of these processes is to obtain more available information about the user/terminal to facilitate assistance. This information and the location of the cell from which the call is originated should be available for forwarding to the emergency dispatcher, if required. The emergency call can not be denied if an RF channel can be found. The emergency call can be initiated by a user dialling the appropriate digits (e.g. 911) or by a terminal feature button. Either means of initiation can begin the process by placing a "normal" call or by invoking special signalling to the network.
+
+**The emergency call re-establishment – loss of RF contact process:** This process occurs when the Radio System Function (RSF) is no longer able to receive RF signals from the terminal during an emergency call. The RSF will attempt to re-establish contact with the terminal. If successful, the reconnection processes undertaken are equivalent to those which follow the handover process, namely, the handover execution process and handover completion process.
+
+**The emergency call termination – dispatcher hang up process:** This process occurs when the emergency operator goes on hook, which is the only means to normally end an emergency call. If the user returns the terminal to on hook condition, then the emergency call does not terminate; if necessary, the above process will be invoked. This emergency call should occur regardless whether a terminal is in its home network, or is in another network (i.e. local network).
+
+**I.3.3.2.8 Terminal equipment validation (TEVA):** The TEVA feature should be considered as a part of the mobility processes of location management (i.e. terminal location registration), call origination, call delivery and at other times as initiated by the network or terminal. The feature enables FPLMTS network operator to identify stolen, lost, suspicious or non-type-approved terminal equipment and then track or prevent the use of this terminal equipment. A blacklist of the identities of individual stolen, lost or suspicious terminal equipment and a white list of the identities of type-approved terminal equipment will be needed.
+
+Manufacturer should provide a terminal equipment identity, for example IMEI (International Mobile Equipment Identity), to be associated with a terminal equipment itself.
+
+**I.3.3.2.9 Cryptographic information management (CIM):** Cryptographic information management is a service feature which manages the secret information associated with cryptographic security mechanism including: the enhanced authentication mechanism, the integrity mechanism, and the encipherment mechanism. This feature is concerned with the generation, distribution, storage, updating, and deletion of cryptographic information whose secrecy or integrity must be assured.
+
+This feature is strongly related to User Authentication (UAUT) and Terminal Authentication (TAUT). Associated with each user and terminal is some information which only that user or
+
+terminal and possibly the network knows. Authentication is based upon the user or terminal convincing the network that it knows the correct secret information through some cryptographic protocol and vice versa. Unlike simple password authentication schemes the secret information is never disclosed. Furthermore, during the authentication process, the user and service provider can generate some shared secret information which can be the basis of other security mechanisms.
+
+The identity specific secret information is normally a key for a cryptographic algorithm. These keys are classified either as asymmetric or symmetric keys depending on the type of algorithm used. With symmetric keys (associated with conventional secret key encryption algorithms) the network needs to know and assure the confidentiality of the value of the key. Alternatively, if the key is asymmetric (associated with public key encryption algorithms) then the network only needs a copy of the public key of the secret/public key pair. Although the public key does not have to be protected from disclosure, the key must be protected from modification so that the public key really corresponds to the secret key of the entity in question.
+
+When public key schemes are used there is only limited security risk in distributing the authentication information to local service providers and the authentication algorithms could be standardized. Local authentication is possible.
+
+With secret key schemes, the keys could be distributed to local service providers; however, this greatly increases the risk of disclosure. Again, a standard authentication algorithm could be used and local authentication is possible.
+
+As an option with secret key schemes, the home service provider may not wish to disclose the secret key information but only distribute sufficient information for a limited number of authentication. Authentication in this case is essentially centralized. The type of information distributed depends on the authentication mechanism which may vary depending on the network involved. For example, the authentication process may need to proceed with only one message from the user to the service provider. The service provider would either have a list of expected authentication message from the home service provider and use these to check the identity locally, or the authentication message may need to be sent to the home service provider for remote authentication. The scheme chosen has implications for security and worldwide roaming.
+
+As another option with secret key schemes, the home service provider may not wish to disclose the secret key information but only distribute sufficient information for a local key being generated. Those local keys would be valid for a limited number of authentication. Authentication in this case is not centralized.
+
+This service feature also provides for the management of cryptographic data associated with encryption. The type of data which should be encrypted depends on the network and may include: user information, especially for radio networks; user identity, and signalling data; and terminal identities.
+
+### **I.3.4 Other services**
+
+**I.3.4.1 Internetwork Freephone (IFPH):** This service allows the served user having one or more installations to be reached from a specific network other than his/her network with a freephone number, and to be charged for this kind of call. The subscriber's network configuration is defined per subscriber direction using customer-specific information resident in multiple networks.
+
+**I.3.4.2 Internetwork Premium rate (IPRM):** This service provides two-way interactive communication between callers in one network and service/information providers in another network. The calling party is charged with a premium rate for this kind of call. It can be available in the public telephone network, whereby a service provider having connections to the public network can be allocated a special telephone number by a network operator, known as premium rate number.
+
+The service provider is able to earn revenue for each call successfully made to this premium rate number. In return, the service provider provides caller with some form of information service via the call connection. Calls to the premium rate number are charged to the caller at special rates.
+
+**I.3.4.3 Internetwork Mass calling (IMAS):** This service is designed to accommodate large volumes of simultaneous calls to a single directory number in another network. It can provide one-way, non-interactive communication between each caller in a given network and a service/information provider in another network. Using this service, the network operator can temporarily allocate a single directory number to the served user. Alternatively, each time a call is made to this number by an end user from another network, for example, an announcement can be played to the end user asking him to input an additional digit to indicate a preference. The choice made can be recorded and a counter incremented. When the service has ceased, the network operator can supply details of the total "votes" cast for each preference to the served user and the special number can be re-allocated.
+
+**I.3.4.4 Internetwork televoting (IVOT):** This service allows a service/information provider in one network to conduct voting or polling over the phone. The caller in another network votes by placing a call to a specific number corresponding to a voting/polling choice. The service provides communication between each caller in a given network and a service/information provider in another network. The service/information provider receives a tally of the number of calls to each number. Televoting enables subscribers to survey public opinions using the telephone network. Persons wishing to respond to an opinion poll can call televoting numbers to register their votes. The charging is to the discretion of the service subscriber. As an option, using this service, the network operator can temporarily allocate directory numbers to the served user. Each time a call is made to one of these numbers by an end user from another network, an announcement can be played to the end user, acknowledging the call, and a count of calls made to this number can be incremented. When televoting has ceased, the network operator can supply details of the total numbers of calls made to each number to the served user in a different network, and the special numbers can be re-allocated. Calls made to these special numbers may be charged at varying rates.
+
+**I.3.4.5 Global Virtual Network Service (GVNS):** The global virtual network service is a global switched VPN service supported by multiple networks (e.g. offered to customers over PSTN and/or ISDN).

Upon successful call set-up, the subscriber is released and the held party is connected to the new destination in a two-party active call.
+
+**I.3.4.10 Call Waiting (CW):** This service allows a user to notify a subscriber of the occurrence of a call termination attempt, while that subscriber is participating in an active call. Upon the subscriber's request, the network is able to place on hold the call party participating in a previous active call, and allow the subscriber to accept the incoming call. The subscriber is then associated
+
+with both calls and able to toggle between the two calls, causing the other call parties to toggle between hold and active conditions.
+
+**I.3.4.11 Hot line (HOT):** The hot line service allows a user to place calls without providing, in the call request, the called party information required by the network to route the call. This routing information is stored in the network by prior subscription. The service also allows terminating restrictions to be provided to ensure that certain hot line subscribers only receive calls from other specified users. For the hot line receiving service, the user may receive calls only from a specified list of parties, a screening list before authorizing termination of the call.
+
+**I.3.4.12 Multimedia (MMD):** This service allows a subscriber to receive or send an integrated communication consisting of mixtures of voice, data, image, and video information. A key capability will be the ability to synchronize and control delivery of information from disparate sources (e.g. voice and data). This will include controlling delivery from multiple sources to a single recipient and from a single source to multiple recipients.
+
+The subscriber will also desire the ability to tailor a particular service to the type of terminating device or subscriber preference (i.e. turning off the video feed). Another key aspect of this service is that additional capabilities may be requested during the call (i.e. adding data capabilities to an existing voice connection).
+
+**I.3.4.13 Terminating Key Code Screening (TKCS):** This service enables a subscriber to screen incoming calls by means of a user-defined key, i.e. pin code. The callers are required to enter this key. In case of success, either the subscriber is alerted or the busy tone is sent to the caller. In case of failure, appropriate information is sent to the caller. The subscriber may activate and deactivate the service.
+
+**I.3.4.14 Message Store and Forward (MSF):** This service enables a user to send a message to be distributed to one or several destination users. Different types of messages (such as voice, data, and fax) may be supported and different methods of delivery and/or times of delivery (such as only to pre-subscribed mail-box holders or direct to any access) may be specified.
+
+**I.3.4.15 International telecommunication charge call (ITCC):** This service allows the holders of a telecommunication charge card to make use of a variety of telecommunication services provided by the card acceptor (visited network) and have the charges billed to the customer's account number by the card issuer (home network). It is described in Recommendations E.113 and Q.86.7.
+
+### **I.3.5 Other service features**
+
+**I.3.5.1 Automatic Call Back (ACB):** This service feature allows the called party to automatically call back the calling party of the last call directed to the called party.
+
+**I.3.5.2 Call Hold (HOLD):** This service feature allows a user to interrupt his/her connection to an existing call, without releasing that call. Some of the resources which were dedicated to that call (e.g. bearer capability) become available for other uses.
+
+**I.3.5.3 Call Retrieve (CRET):** This service feature allows a user to re-establish his/her connection to a call previously placed on hold.
+
+**I.3.5.4 Call Transfer (CT):** This service feature allows a user who is a party in two separate calls, to cause the other two parties to those calls to be connected to each other, releasing him/her from both.
+
+**I.3.5.5 Call Toggle (CTOG):** This service feature is applicable to a user who has one active call and one on hold. It allows him/her repeatedly to select the currently held party as the new connection, the previously connected party being automatically put on hold.
+
+**I.3.5.6 Call Waiting (CW):** This service feature informs a user already engaged in a call that another party is trying to establish a connection to him/her. Signalling means are provided to enable the user to instruct the network as to what further action it should take.
+
+**I.3.5.7 Meet-Me Conference (MMC):** This service feature allows the user to reserve a conference resource for making a multi-party call, indicating the date, time, and conference duration. At the specified date and time, each participant in the conference has to dial a designated number which has been assigned to the reserved conference resource, in order to have access to that resource, and therefore, the conference.
+
+**I.3.5.8 Multi-Way Calling (MWC):** This feature allows the user to establish multiple, simultaneous telephone calls with other parties.
+
+**I.3.5.9 Call Pick-Up (CPU):** This service feature enables a user to associate a call request to an already alerting call. The alerting call awaits answer while the user originating call pick-up signals to the network a desire to connect to the alerting call. The network then connects the call parties.
+
+**I.3.5.10 Calling Name Delivery (CND):** This service feature gives to the network operator the capability to display/announce the name of the calling party to the calling name delivery user (the called party) prior to answer, thus allowing this user to screen or distinctively answer the call.
+
+**I.3.5.11 Services On-Demand (SOD):** This service feature enables a user to request new services while initiating or involved in a call, e.g. multi-way calling at a pay phone. This includes the capability to invoke new services for the duration of the call.
+
+**I.3.5.12 Message Waiting Indication (MWI):** This feature enables a user to be informed that messages for his attention are waiting.

+**I.3.5.20 Resource Allocation (RAL):** This service feature enables the allocation, in advance and for a certain period of time, of pooled resources (e.g. conference bridges) required for a service.
+
+**I.3.5.21 Delivery of Complementary Information (DCI):** This service feature enables a calling user to supply to the network complementary information (e.g. an account number and a password) associated with the call set-up information.
+
+**I.3.5.22 Service Indication (SIND):** This service feature enables the called party to receive an indication concerning the presented call (for instance, an application to the freephone service would be the indication that the charge is to be supported by the called party; an application to the call forwarding service would be the forwarding number).
+
+**I.3.5.23 Service Negotiation (SNEG):** This service feature enables the parties involved in a call to negotiate the bearer services, teleservices and supplementary services to be provided for the call, depending on the services subscribed by the parties, the terminal and network capabilities, etc. This negotiation may take place both during call set-up and during the active call phase.
+
+**I.3.5.24 Call Forwarding (CF):** As defined in Recommendation Q.1211. Nevertheless, this feature is listed here for inclusion in IN CS-2 because some useful capability had not been fully included in IN CS-1. Refer to Annex B of Recommendation Q.1211 for more detail and for a template description of this feature.
+
+**I.3.5.25 B-ISDN Multiple Connections Point-to-Point (BI-MCPP):** This service feature enables a user to make a call between two points involving multiple connections, e.g. voice, audio, video, and/or data. This service feature may make use of B-ISDN point-to-point connection service feature (BI-PPC) and need other service features such as multi-connection.
+
+**I.3.5.26 B-ISDN Multi-Casting (BI-MCAST):** This service feature enables the network to set up multiple connections among multiple parties where the connections are point-to-multipoint unidirectional. This service feature may make use of B-ISDN point-to-multipoint connection service feature (BI-PMC) and/or B-ISDN multipoint-to-point connection service feature(BI-MPC) and need other service features such as leaf control.
+
+**I.3.5.27 B-ISDN Conferencing (BI-CONF):** This service feature enables the network to set up multiple connections among multiple parties where the connections are multipoint to multipoint.

+**I.3.5.28 Call Connection Elapsed time limitation (CCEL):** This service feature allows a calling party to make calls and communicate with one or more parties within a duration time predefined on a subscription basis. A tone or an announcement may be provided to the parties (i.e. calling and called parties) to indicate that the call will be cleared in a short time.
+
+**I.3.5.29 Special Facility Selection (SFS):** This service feature enables a call to be routed via a special facility (e.g. a virtual leased line) under the determination of service control.
+
+**I.3.5.30 Concurrent Features Activation with Bi-control (CFA-BC):** This service feature enables a call to be influenced by some features at two different point concurrently, such as originating side and terminating side. With this feature, a set of features is pre-defined in one service logic and controlled by its context with bi-control relationship.
+
+**I.3.5.31.a Customized Call Routing with Public networks (CCR-PU):** This service feature permits the public network to access other public networks for call processing and routing information. According to the subscriber's needs, the accessed public network determines each incoming call's appropriate destination, which could be local, national, or international telephone number. This action will remain under the sole control of the accessed public network, allowing for convenient updating, as well as confidentiality. CCR service feature can be provided either as a originating or as a terminating trigger feature.
+
+**I.3.5.31.b Customized Call Routing with Customers (CCR-CU):** This service feature permits the public network to access customers systems for call processing and routing information. The accessed system (which may be in private network, simple database, a PABX, or a terminal) determines each incoming call's appropriate destination, which could be local, national, or international telephone number. This action will remain under the sole control of the accessed system, allowing for convenient updating, as well as confidentiality. CCR service feature can be provided either as a originating or as a terminating trigger feature.
+
+**I.3.5.32 Internetwork Service Profile Interrogation (ISPI):** This service feature enables a user to interrogate (read only) the current contents of the user's service profile. The profile information could include information such as telecommunication services subscribed to, default parameters, activated supplementary services, current registrations for incoming and outgoing calls, etc.
+
+The identification and authentication procedures should be required at beginning. The network will respond with the requested information to the user if the information can be disclosed. Any rejection could depend on the authentication procedure, service profile restriction.
+
+**I.3.5.33 Internetwork Service Profile Modification (ISPM):** This service feature enables a user to modify (read and write) the appropriate user's service profile parameters that are allowed to be modified. Such parameters could be activation or deactivation of supplementary services, various default parameters, or PIN code.
+
+The identification and authentication procedures should be required at beginning. The network will respond with the requested information to the user if the information can be modified. Any rejection could depend on the authentication procedure or service profile restriction.
+
+**I.3.5.34 Internetwork Service Profile Transfer (ISPT):** This service feature enables service profile information to be transferred to other service profile storage locations in other networks. It is required to enable user profile information portability. The value of data which are simultaneously stored in some networks should be consistent. Information which is transferred to each visited network may depend on the contract with home network. The information updated in a visited network is transferred to the home network and conversely.
+
+**I.3.5.35 Reset of UPT registration for incoming calls (IRUR):** This service feature enables any person (the third party), even if not a UPT user, to reset any UPT registrations for incoming calls on the third party's terminal.
+
+**I.3.5.36 Mobility Call Origination (MCO):** The MCO feature covers both mobile call origination and UPT call termination. It is initiated within the mobility process of call origination. This feature does not require any location registration of terminal/users and allows a provision of customized authentication of terminal/user for call origination. This feature is independent of the registration states of the user and other users at the terminal.
+
+For terminals, due to the radio access nature of third generation mobile system such as FPLMTS, the timing of the creation of the access bearers for FPLMTS should be flexible, i.e. the off-air call set-up scheme may be possible.
+
+**I.3.5.37 Mobility Incall Delivery (MID):** The MID feature covers both mobile user call termination and UPT incall delivery.
+
+**I.3.5.38 Data communication between different protocol terminals (DCPT):** This service feature enables a mobile terminal to handle data communication between different protocol terminals in the intra-network or internetwork environment. This service feature enables a mobile terminal to handle data communication between different protocol terminals in the intra-network or internetwork environment. This type of data communication service feature is performed by protocol conversion unit within SRF upon requesting the data communication from the subscriber.
+
+**I.3.5.39 Charge Determination (CDET):** This service feature enables the calculation of charges related to a call. The charged party(s) may include FPLMTS subscribers, UPT subscribers and/or other calling parties. Charges may be based on usage and chargeable events/procedures (e.g. location update and service profile management). Two methods of charge determination are possible.
+
+The first method is off-line charging. Relevant call information (i.e. a call record) is stored by the network at the end of a call. Call records are periodically processed off-line to calculate call charges. Call charge records are then transferred in batch-mode to the local billing centre, which may then forward them to the home service providers or home network designated locations for subsequent billing of their subscribers.
+
+The second method is on-line charging. Charging information is calculated in real time during the call. This method supports calls from pay phones, charge metering and advice of charge. Some calls may involve both on-line and off-line charging (e.g. for split charging).
+
+**I.3.5.40 Charge Card Validation (CCV):** This service feature provides the ITCC service an authentication feature to compare user-side information, provided to the visited network, with information stored in the home network. Authentication attempts and fails are to be recorded for security purposes.
+
+**I.3.5.41 Call Disposition (CD):** This service feature provides the ITCC service the means to verify that the card has enough spare credit (e.g. the card usage value has not been exceeded) to give the permission to make the call. It implies that the usage of the card against the credit limit is tracked. The visited network sends to the home network an indication of the call card usage at the end of the call. The home network can accordingly decrement the current credit usage and, if exceeded, subsequent calls at authentication time are inhibited.
+
+**I.3.5.42 User Service Interaction (USI):** This service feature enables a user to interact with, and thus to send or receive information to or from, a service in association with a call involving this service.
+
+**I.3.5.43 Enhanced Call Disposition (ECD):** This service feature provides a means to cut down the call as soon as the card usage is exceeded. As soon as the card usage is exceeded, the call should be cut down and subsequent authentication requests should be inhibited according to pre-defined time basis (e.g. monthly and daily). As the card profile might imply different customers (such as the case for a multi-PIN card), concurrent usage, if any, should be tracked from different visited network locations. The previous requirements can be accomplished in different ways; anyway the home network is required to record the database access, in order to allows subsequent actions/requests during the same session. To accomplish the ECD requirements, the visited network gets a credit usage limit indication back in the authentication response. In this case the visited SCF is charged with real time control of the card usage and it has to cut down the call, if needed.
+
+## **I.4 Service management services**
+
+### **I.4.1 General**
+
+This subclause intends to provide short prose descriptions of targeted service management services and service features.
+
+### **I.4.2 Definition**

The service customization parameter value are set through negotiation with a network operator and/or service provider.
+
+**I.4.2.6 service management processes** are the following types of activity performed by network operators/service providers:
+
+- **service deployment** is the introduction of a service into the IN-structured network in a subscriber independent way;
+- **service provisioning** is the initial installation and deployment of necessary resources and data in appropriate network elements to provide a service subscription to a specific subscriber;
+- **management during the service utilization** contains service monitoring, service maintenance, service traffic management, audit administration, and billing activities.
+
+The capability of the service management service can be recognized as follows:
+
+- a) Generic: Capabilities are generic for all services;
+- b) Service specific: Capabilities are service specific but common for service subscribers;
+- c) Service subscriber specific: Capabilities are service subscriber specific as well as service specific.
+
+### **I.4.3 Service management service/service feature**
+
+#### **I.4.3.1 Service customization service**
+
+**I.4.3.1.1 Telecommunications Service Customization (TSC):** Allows customization of telecommunication service to be provided to a specific subscriber according to requirements. There are two types of TSC:
+
+- Generic TSC: Customization parameters for telecommunication service are service-specific but common for subscribers. A network operator sets subscriber-specific initial values for each necessary customization parameter to specify the telecommunication service features.
+- Subscriber-specific TSC: TSC is fully subscriber-specific, so it requires the creation of subscriber-specific telecommunication service.
+
+**I.4.3.1.2 Service Control Customization (SCC):** Allows customization of service control service to be provided to a specific subscriber according to requirements. There are two types of SCC:
+
+- Generic SCC: Service control parameters for service control service are service-specific but common for subscribers. A network operator sets initial values for each necessary customization parameter to specify service control parameters available to the subscription.
+- Subscriber-specific SCC: fully subscriber-specific, so it requires the creation of subscriber-specific service control parameters.
+
+**I.4.3.1.3 Service Monitoring Customization (SMC):** Allows customization of service monitoring service to be provided to a specific subscriber according to requirements. There are two types of SMC:
+
+- Generic SMC: Service monitoring data for service monitoring service are service-specific but common for subscribers. A network operator sets a subscriber-specific initial list of service monitoring data to be collected for a subscription.
+- Subscriber-specific SMC: SMC is fully subscriber-specific, so it requires the creation of subscriber-specific service monitoring data collection lists.
+
+#### **I.4.3.2 Service control service**
+
+**I.4.3.2.1 Subscriber Service Activation/Deactivation (SSAD):** Allows the subscriber to activate/deactivate a subscription to a telecommunication service. While the service is deactivated, network provides the default announcement which indicates that the telecommunication service stops.

+
+**I.4.3.2.4 Subscriber Service Limiter (SSL):** Allows the subscriber to restrict the number of simultaneous usage of the telecommunication service.
+
+**I.4.3.2.5 Subscriber Service Invocation (SSI):** Allows the subscriber to invoke the telecommunication service. The target telecommunication service should be designed to be invoked using SSI.
+
+#### **I.4.3.3 Service monitoring service**
+
+**I.4.3.3.1 Subscriber Service Report (SSR):** Allows the subscriber to get a report on the usage of service subscriptions. The report may involve some statistics, such as the number of calls and mean call duration under specific conditions like time of day, origination area and termination telephone.
+
+**I.4.3.3.2 Billing Report (BR):** Allows the subscriber to get billing report of a chosen type. Several types of billing report may exist, e.g. total, terminating telephone basis, and group basis.
+
+**I.4.3.3.3 Subscriber Service Status Report (SSSR):** Allows the subscriber to receive the following status on each subscription to a telecommunication service:
+
+- performance (e.g. number of calls per measurement period);
+- congestion (e.g. number of blocked calls per measurement period);
+- fault (e.g. number of failed calls per measurement period).
+
+**I.4.3.3.4 Subscriber Traffic Monitoring (STM):** Allows the subscriber to monitor real-time usage of service subscriptions (e.g. the number currently processing calls in mass calling service, and the length of queue in call-queueing service).
+
+**I.4.3.3.5 Subscriber service Management service Usage Report (SMPUR):** Allows the subscriber to get a report on the usage of service control/monitoring service.
+
+#### **I.4.3.4 Other service management services**
+
+**I.4.3.4.1 Subscriber Service Testing (SST):** Allows the subscribers to perform their own test service subscriptions.
+
+**I.4.3.4.2 SMP Usage Report (SUR):** Allows the subscriber to get a report on usage of SMP (e.g. number of login sessions, length of each, CPU usage, and mass storage usage).
+
+**I.4.3.4.3 Subscriber Security Control (SSC):** Allows the subscriber to change security parameters (e.g. password).

+# FOREWORD
+
+The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.1301 was prepared by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 17th of October 1995.
+

+
+# NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+# **SUMMARY**
+
+This Recommendation identifies the Architecture that supports TASC (Telecommunication Applications for Switches and Computers) and is one in the Q.1300-Series Recommendations on TASC. The main purpose of TASC is to allow applications running within the network user's environment to integrate telecommunication services with computing facilities. This would typically allow business applications to use TASC to integrate the computer workstation and telephone at the user's desktop. This Recommendation does not define how the elements of the architecture are implemented. Part of the definition of the TASC architecture includes the TASC objects which are the basis for the TASC Functional Services.
+
+# **INTRODUCTION**
+
+The concept of TASC, which this architecture supports, is described in Recommendation Q.1300, TASC Overview. Although the TASC architecture identifies, describes and models interactions between the TASC objects, it does not specify how they should be implemented. In addition to call and telecommunication device objects, the role of Agents (as in ACD system) is modelled.
+
+# **BACKGROUND**
+
+This Recommendation is based on the experience of ECMA (Standardising Information and Communication Systems) and ANSI (American National Standards Institute) member companies in developing switch-to-computer interfaces and takes directions from CSTA (Computer Supported Telecommunications Application) and SCAI (Switch-to-Computer Application Interface) standards.
+

+
+# **1 Introduction**
+
+This Recommendation defines the architecture for TASC and identifies the various objects which represent information which the TASC interface operates on. The concept behind TASC is described in Recommendation Q.1300, which is considered essential reading prior to this Recommendation, and the services that the architecture supports are defined in Recommendation Q.1302. Recommendation Q.1303 defines the requirements for managing the objects herein described.
+
+# **2 Scope**
+
+This Recommendation defines an architecture for the support of Telecommunication Applications of Switches and Computers. The architecture supports the communication between the switch and computer and the services conveyed by that communication. This Recommendation considers how the information communicated is represented. TASC does not define how the aspects making up TASC in either the switch or computer environment are implemented.
+
+The emphasis of TASC has been to define third-party call control functions which also encompasses first-party call control. TASC is independent of any underlying mechanism and is applicable to public, private and hybrid networks. TASC is designed to be flexible in order to support other communication environments in addition to those based upon ISDN and Intelligent Network (IN) principles.
+
+It is focused on providing an application service interface between a switch and computer.
+
+TASC supports both a single-ended call (originating and terminating) view as well as a global call view.
+
+The TASC architecture accommodates different ways of viewing calls available in implementations but models these views on stable and accepted models of how calls work.

+# 5 Architecture
+
+The TASC Architecture provides a framework for communication between a computer and a switch. Recommendation Q.1300 describes the environments in which TASC may be used.
+
+## 5.1 Domains
+
+Domains identify the area that TASC may manipulate and influence.
+
+### 5.1.1 Domain
+
+Call domains ultimately deal with controllable and visible telecommunication devices in TASC's problem space. Such devices are referred to as Communication Entities (CE) so as to avoid confusion with connotations of specific types of devices.
+
+#### 5.1.1.1 Control and visibility
+
+TASC deals with the control and visibility of calls as they originate and terminate at CEs. All TASC functions revolve around this fundamental principle. Therefore, the problem space involves calls which can originate, terminate, or become visible at CEs. The CEs defined by TASC include Line CEs and Distribution CEs.
+
+When dealing with a call the switch is transparent to the application. TASC does not attempt to directly control or provide visibility of switches and computers. So switch and computer objects are not in the TASC problem space. Only the CEs related to or attached to switches and computers involved in the calls are visible.
+
+#### 5.1.1.2 Objects of interest
+
+TASC consists of a set of functional services that provide peer-to-peer applications with a standard means of communication for the control and visibility of calls. Ultimately it is the peer-to-peer applications which know the objects of interest. Peer-to-peer applications not only have a communication application context, but they also have a common, and agreed, set of CEs in the object space. In other words, the two applications know the CEs over which they have control and visibility. This object space is either statically or dynamically defined. The locations of the objects are transparent to TASC. This is depicted in Figure 1 below.
+
+![Diagram illustrating the transparent location of CEs. A Computer and a Switch are shown, each containing an Application and a TASC component. The Applications are connected to the TASC components, which are in turn connected to a central TASC component. The central TASC component is connected to a circle labeled 'Operation Domain' containing three CEs (CE 1, CE 2, CE 3). Arrows indicate 'Physical communication' between the TASC components and the CEs. A note states 'Object location is transparent to TASC'. A reference code 'T1168020-94/d01' is present.](fc46871d72c65d3381d9201646d23439_img.jpg)

To the right is a 'Switch' box containing an 'Application' and a 'TASC' (oval). The 'Application' is connected to the 'TASC'. Below the 'Switch' box is another 'TASC' (oval). A central 'TASC' (oval) is connected to the 'TASC' in the 'Computer', the 'TASC' in the 'Switch', and the 'TASC' below the 'Computer'. Below the central 'TASC' is a circle labeled 'Operation Domain' containing three boxes labeled 'CE 1', 'CE 2', and 'CE 3'. Arrows point from the central 'TASC' to each of the 'CE' boxes. A double-headed arrow labeled 'Physical communication' connects the 'TASC' below the 'Computer' and the 'TASC' below the 'Switch'. A note with an arrow pointing to the 'Operation Domain' circle states 'Object location is transparent to TASC'. In the bottom right corner, the text 'T1168020-94/d01' is present.

+
+#### 5.1.1.3 Operation and working domains
+
+The identification of CEs of interest to an application may occur through static (subscription arrangements) and dynamic means (messaging). The identified CEs are the operation domain for a particular application. Once that application has begun processing, the transitional objects such as CVs (calls views), CPs (connections between CEs and calls), and Users may be created and destroyed as a result of TASC related activity. The working domain may expand or contract during the lifetime of the application but may not expand to include CEs outside of the defined operation domain. It is the set of CEs (objects) which can be monitored by an application which form a Working Domain. The relationship between Operation and Working Domain is illustrated in Figure 2.
+
+TASC does not provide the ability for applications to acquire and lock the use of a CE for the exclusive use of a particular application process. Therefore coordination of applications and their use of CEs is outside the scope of TASC.
+
+For example, in a customer service department for a company which has agents and an ACD system, the object space for the application is the set of objects representing the agent CEs and ACD pilot numbers where calls are originated, terminated, or become visible. This Operation Domain does not include end users (i.e. the customers' phones), external phones where service calls are originated, or the switches or computers. The objects which can be monitored are the agent CEs and pilot numbers, and these represent the domain of objects of interest in the calls. This object space is defined for, and known by, the peer-to-peer applications. The locations of the objects are transparent to TASC. The objects actually monitored form the Working Domain.
+
+### 5.1.2 Call views
+
+TASC defines a call view object to represent a call in the problem space. A call view has a call view identifier, a call view state, and participants or parties. The call view identifier is unique within the Operation domain. That is, in the communication between the peer applications, the Call View ID identifies a unique call. No two calls visible to the peer applications may have the same Call view ID.

The Working Domain is a smaller circle within the Operation Domain. The Call Monitor Domain (global view) is a dashed rectangle enclosing some CEs.

A smaller circle labeled 'Working Domain' is also inside the Operation Domain. Within the Working Domain, there are three 'CE' boxes, each enclosed in a dotted circle labeled 'Individual Device Monitor Domains (single-ended view)'. Lines connect various 'CE' boxes, with a label 'CE's involved in the life of a single call' pointing to one of the connections.

+
+#### 5.1.2.1 Single-ended view
+
+The single-ended view of a call is the view of call progress and call states from a CE's perspective. The TASC object model for a two-party call splits into originating and terminating views. For example, for a basic call, when that CE is originating a call, the switch provides the single-ended view incorporating the originating call model events. The actions of the terminating side are implied in those events. When that CE is terminating a call, the switch provides the single-ended view incorporating the terminating call model events. The actions of the originating side are implied in those events but cannot be guaranteed. Information available about that CE and other CEs in the call is made available in the single-ended view by the switch.
+
+Single-ended views are independent of each other. A switch may allocate separate call view identifiers for each single-ended view.
+
+#### 5.1.2.2 Monitoring within a single-ended view
+
+TASC defines a single-ended view for the associated CE. This means that TASC defines call events which are reported for calls based on whether the call is originating, terminating or distributing at the CE. Thus if a CE is being monitored and a call terminates at the CE, the terminating call events may be reported. If a CE is being monitored and a call originates at the CE, the originating call events may be reported. Events may also be reported for monitored CEs at which calls appear such as Distribution CEs.
+
+#### 5.1.2.3 Global view
+
+An alternative to the single-ended view is the global view where the view of call progress and call states are from the domain's perspective of a call. Thus all parties associated with a specific call can be visible with a global call view. Each party associated with the call still needs to adhere to the relevant basic call model (originating/terminating or distribution) but are united by a common identifier for the call.
+
+The extent of a global call is limited by the operation domain, thus a call that goes outside of the Operation Domain may only be able to support a single-ended view in some circumstances.
+
+#### 5.1.2.4 Monitoring within a global view
+
+The method used to invoke device and call monitoring differs but the event reports generated remain the same. With device monitoring, events are generated as a result of a change in the Call View state currently at the monitored device. With call monitoring, events are generated as a result of Call View state changes anywhere within the call. Two forms of Call Monitoring are defined within TASC:
+
+- 1) A Call Monitor set on a call will generate events as a result of Call View state changes anywhere within the call. A call where some CEs are outside the TASC operation domain may report less call progress information; at least one CE must reside within the Operation Domain for call monitoring to function. This type of monitor will follow a single call. It may only be invoked once the call has been created and a Call View ID returned to the application, e.g. after a TASC Make Call Functional Service request or Call-Arrived event (see Recommendation Q.1302).
+- 2) A Call Monitor set on a CE will generate events as a result of a Call View state change for every call that has involved the specified CE since the call monitor was invoked. A call where some CEs are outside the TASC operation domain may report less call progress information; at least one CE must reside within the Operation Domain for call monitoring to function. This type of monitor will follow all calls which have contact with the specified CE, e.g. a call monitor on a distribution CE will monitor all calls which are distributed by that CE. Events will be generated during the complete life of each call distributed.
+
+Call monitoring is considered further in clause 6.
+
+#### 5.1.2.5 Calls between CEs
+
+As calls originate, arrive, terminate and disappear from CEs within the working domain, events are reported based on the single-ended view, features in effect, and characteristics of a CE. Since all calls are uniquely identified by a Call View ID, any and all events which specify the same Call View ID in the communication protocol between the peer applications refer to the same call. The switches assign and manage Call IDs although a management function may manipulate these ID's as described in Recommendation Q.1303
+
+#### 5.1.2.6 Call view ID
+
+Call IDs are assigned and managed by the switch and must uniquely identify calls at CEs. These Call IDs must be unique within the Working Domain between peer applications. How the switch assigns Call IDs to calls between CEs in the operation domain (i.e. whether or not it uses the same Call view ID for both originating and terminating objects and events) must be understood and known by the applications prior to association. Thus Call view ID assignment is part of the application rules and in part a function of the type of network – public, private or hybrid. It should be noted that a request for a global call view may be rejected based upon the capabilities of the signalling environment in which the applications exists.
+
+#### 5.1.2.7 Global call view ID
+
+In a call between two CEs in a working domain, a Global Call is characterized by the same Call View ID being assigned for both originating, terminating and distributing endpoints. The Call view ID is unique in the Working Domain.
+
+Management of identifiers is achieved via parameters included in Functional Service responses and Event Reports. Identifiers cease to be valid when their context vanishes. If a call ends, its Call View Identifier is no longer valid to refer to that call.
+
+If a call changes its Call View Identifier when a Conference or Transfer occurs, identifiers are provided to link the old Call View Identifier to the new Call View Identifier. Similarly, if a CE Identifier is changed identifiers are provided to link new and old identifiers. Event Reports are used to report state changes.
+
+Identifiers can be re-used. Once an identifier has lost its context, it may be re-used to identify another object.
+
+Note that it is recommended that implementations do not re-use identifiers prematurely.
+
+Individual Call View and CE Identifiers are not guaranteed to be globally unique. TASC requires that the combination of Call View and CE Identifier be globally unique within an operation domain. To accomplish this, either the Call View Identifier, or the CE Identifier (or both) shall be globally unique.
+
+# **6 Call monitoring**
+
+## **6.1 Introduction**
+
+Call Monitoring is a Functional Service which will provide call progress information for all Communication Entities (CEs) involved in a call. During the life of a call, regardless of the operations performed on that call, this service will continue to provide call progress information for as long as the call remains within the TASC Operation Domain. Call Monitoring will continue to provide call progress information after transfers, forwarding and conference operations.
+
+## **6.2 CE monitoring versus call monitoring**
+
+CE monitoring will report call progress information while a call resides at CEs which have active CE monitors; this is known as the TASC Working Domain. The collection of CEs on which these monitors have been placed remains fairly static; they are not changed by any particular call. An application using CE monitoring must therefore define precisely the CEs from which it wishes to receive call progress information. The complete collection of CEs on which an application may set monitors is known as the TASC Operation Domain.
+
+During the life of a single call many CEs may participate; some with active CE monitors and some without. An application may therefore wish to invoke a monitor which will report call progress information throughout the life of a call, regardless of the CEs which are involved in that call. Call Monitoring will provide an application with this information without having to explicitly place monitors on all the CEs which have participated in that call. With Call Monitoring, the domain of the monitor changes very dynamically to include the collection of CEs involved during the life of a particular call. Figure 2 illustrates the relationship between the various TASC domains.
+
+The TASC Operation Domain is the collection of CEs on which an application may place a monitor. The TASC Working Domain represents the collection of CEs within the Operation Domain on which an application has placed CE monitors independently of any particular call. The Call Monitor Domain is the collection of CEs within the Operation Domain which participate in a single call when call monitoring has been enabled. There will be a Call Monitor Domain, dynamically changing as the call progresses, for each call monitor invoked. When a call dies, then its associated call monitor domain also dies. The Call Monitoring domain is only constrained by the Operation Domain and operates independently from the Working Domain but may include CEs within the Working Domain. When a CE monitor is invoked then the domain of that monitor is restricted to the individual CE, i.e. the individual CE monitor domain.
+
+## **6.3 Call monitoring operation**
+
+TASC Functional Services such as Transfer, Conference and Forwarding (see Recommendation Q.1302) will not prevent a Call monitor from following the call even if the Call View ID changes. A Call Monitor identifier will be included in each event reported.
+
+For a Call Monitor set on a CE a Call Monitor identifier will be returned. This Call Monitor identifier will be reported for all calls which involve that CE while the Call monitor is active. This Call Monitor identifier is distinct from any CE Monitor identifier. As an example, a Call Monitor placed upon a Distribution CE will generate call progress events for all calls which are distributed by that distribution CE and will use the same Call Monitor identifier.

+# 7 TASC interfaces
+
+## 7.1 Single TASC interface
+
+A single viewing point covers scenarios where there is a single TASC interface. There is a single switch, a single computer, and a single application context instance. The computer thus has control and visibility of calls from a single point. However, the operation domain of CEs which can be monitored may all be local, all remote, or mixed between local and remote.
+
+## 7.2 Multiple TASC interfaces
+
+Multiple viewing points exist when there are multiple TASC interfaces for the same operation domain. This may involve multiple interfaces between a single switch and a single computer or multiple interfaces with multiple switches and computers. The scenario calls for a common domain of CEs known by all applications on which monitors can be placed. There are many peer-to-peer applications operating in a cooperative manner. However, in order to cooperate they all share a common definition of the operation domain which can be monitored. The operation domain of CEs which can be monitored may all be local to a single switch or distributed between switches.
+
+There may be proprietary communication links between computers, between switches, and/or between computers and switches, to facilitate coordination and information flow. These links and information exchange are outside the scope of TASC. See Figure 3.
+
+![Diagram illustrating multiple TASC interfaces and their interaction with an operation domain.](5e92d9e8e9ce204e405bff2367f88176_img.jpg)
+
+The diagram shows a network architecture with multiple components. At the top, 'Computer M' and 'Switch N' are shown. Each contains an 'Application' box connected to a 'TASC' circle. A thick horizontal line connects the 'Application' in Computer M to the 'Application' in Switch N. Below this, 'Computer 1' and 'Switch 1' are shown in a similar configuration. A thick horizontal line connects the 'Application' in Computer 1 to the 'Application' in Switch 1. Both 'Computer 1' and 'Switch 1' have multiple overlapping boxes behind them, representing multiple instances. At the bottom, a double-headed arrow labeled 'Physical Communication' connects the 'TASC' in Computer 1 and the 'TASC' in Switch 1. On the right, a large circle labeled 'Operation Domain' contains three boxes labeled 'CE 1', 'CE 2', and 'CE 3'. Dotted lines connect the 'TASC' in Computer 1, the 'TASC' in Switch 1, the 'TASC' in Computer M, and the 'TASC' in Switch N to this 'Operation Domain'. A text label 'Object location is transparent to TASC' is near the 'Operation Domain'. A text label 'Call IDs must be unique in the information flow between peer applications' is near the top left. A small code 'T1168040-94/d03' is in the bottom right corner of the diagram area.

+Cooperating Applications
+
+In both ways of viewing calls identified in this Recommendation, the following is true:
+
+A call between two CEs in the operation domain is a Global Call view ID if the same Call view ID is assigned for both the originating and terminating events.
+
+The locations of the CEs are transparent to TASC. If a CE does not reside on the local switch, capabilities outside of TASC must exist to place a monitor on this 'remote' CE, signalling must exist to facilitate information flow between switches or computers, and global Call view ID management (i.e. management of Call view IDs between multiple switches) must be defined and provided. This is a function of the scope of the application, the type of network (public, private), and network capabilities.
+
+In a single interface, all CEs are viewed and controlled over a single interface regardless of location. With multiple interfaces, CEs may be viewed and controlled from multiple points but the views at all points are considered with Global Call IDs.
+
+### **In summary**
+
+- 1) TASC supports the following concepts: Operation Domain, Working Domains, Single-ended Calls View and Global Call Views.
+- 2) Operation Domains are defined prior to application initiation. Working Domains are identified by dynamic means and may include a subset of those CEs which were identified as members of the Operation domain.
+- 3) The physical locations of monitored CEs are transparent to TASC.
+- 4) A Global Call View is a function of Call view ID management and assignment and thus a function of the switch, application, and/or network. Call view ID management is implementation specific. TASC provides the flexibility to support different Call view ID management schemes.
+- 5) TASC does not define standardized signalling or information flow between applications in a distributed environment to facilitate coordination and control of calls across multiple TASC interfaces. However, TASC provides the basic information necessary to facilitate that coordination and control.

+# **8 TASC switching model**
+
+The TASC switching model provides an abstract view of switching objects and their behaviour. This switching model consists of TASC objects, their models, and their relationships.
+
+## **8.1 TASC objects**
+
+The following objects for TASC have been identified (see Figure 4):
+
+**Communication Entity (CE)** – An entity that originates, terminates, or becomes visible in a call.
+
+**User** – An entity that makes use of a CE (e.g. initiates a call or answers a call).
+
+**Call View (CV)** – An abstraction of a call which represents the progression of a Call at a CE from the standpoint of a CE involved in a call.
+
+**Communication Party (CP)** – An associative object that maintains the relationship between a call and CE.
+
+### **8.1.1 Communication Entity**
+
+#### **8.1.1.1 Description and behaviour**
+
+An entity that originates, terminates, or becomes visible in a call. Many users, calls, and CPs may be associated with each CE.

+## 8.2 Communication Party
+
+### 8.2.1 Description and behaviour
+
+When a CP is specified by the computer it should at least identify the CE. However, the omission of a Call View should not make the CP ambiguous to the switch (i.e. preventing the switch from identifying a single relationship).

+## 8.4 Call View
+
+There is a relationship among the CEs and Call Views. For a particular CE a particular Call View is presented. This Call View may present a unique set of events which is derived from the call related attributes of the CE. Each Call view presents a single-ended view of a call which is the view of call progress and call states from a switch's perspective for that particular CE.
+
+The call view for a Line CE is separated into originating and terminating Call Views.

+
+# 9 Call view states
+
+The call view states are an abstraction of the call processing activity in the switch that particularly relates to a CE. Not all call processing activities are reflected in the TASC call view. For example, during the PENDING state, the destination CE address information is collected, yet the collection of the digit is not reported to the computer.
+
+Call view state transitions are reflected by call progress events which are reported at the connection. These call progress events uniquely indicate the new call view state.
+
+The following template is used to describe the call states:
+
+**Description** – Describes the state.
+
+**Entry Event Reported** – Identifies the event reported for the state transition.
+
+## 9.1 Call View State descriptions

+- 5) ESTABLISHED
+- 6) FAILED
+
+#### 9.1.1.1 NULL state
+
+##### Description
+
+The state where no call exists from the perspective of the TASC single-ended view. For example, the switch may verify the authorization of this CE to place an outgoing call with given properties (e.g. bearer capability or CE restrictions) before exiting the NULL state. The type of authorization may vary for different types of originating resources.
+
+**Entry Event Reported:** Call\_Cleared.

+
+The agent Model consists of the concepts of agent States and State Transitions.
+
+#### 9.1.4.1 Agent states
+
+The following states are defined for an agent:
+
+|                          |                                                                                                                                                                                                                                                                                     |
+|--------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| AGENT NULL               | The state where an Agent is not logged on to a CE. Logging-on to a CE causes a transition from this state and Logging-off from a CE causes a transition to this state.                                                                                                              |
+| AGENT NOT READY          | The state where an Agent is logged on to a CE but is not prepared to handle calls distributed by the distribution CE. An Agent may receive calls which are not handled by the distributor while in this state.                                                                      |
+| AGENT READY              | The state where an Agent is logged-on to a CE and is prepared and waiting to handle calls from the distribution function.                                                                                                                                                           |
+| AGENT BUSY               | The state where a CE, on behalf of an Agent, participates in a call.                                                                                                                                                                                                                |
+| AGENT WORKING AFTER CALL | The state where a CE, on behalf of an agent, inactively participates in a call. While in this state the agent cannot receive further calls from the distributor function but may well be performing administrative duties for a previous call, e.g. updating a business order form. |

+| AGENT WORKING AFTER CALL | Agent_logged_off | Agent_not_ready | Agent_ready |            |                          |
+
+The agent events are:
+
+- Agent\_Logged\_On
+- Agent\_Logged\_Off
+- Agent\_Not\_Ready
+- Agent\_Ready
+- Agent\_Busy
+- Agent\_Working\_After\_Call
+
+An agent will have access to both a data terminal for communicating to the application and a telephony terminal for communicating to the switch. An agent may perform operations at both of those terminals. If an agent logs on by using the telephony terminal, then the computer application will be informed of state changes by the events identified above. If an agent logs on by using the data terminal, then state changes will be notified to the switch by use of the Manipulate Agent Functional Service as defined within the TASC Functional Service definitions.

+## **Recommendation ITU-T Q.1704**
+
+# **Functional network architecture for IMT-Advanced**
+
+## **Summary**
+
+Recommendation ITU-T Q.1704 specifies a long-term high-level network architecture for IMT-Advanced specified in Recommendations ITU-T Q.1702, Q.1703 and ITU-R M.1645.
+
+## **Source**
+
+Recommendation ITU-T Q.1704 was approved on 14 October 2008 by ITU-T Study Group 19 (2005-2008) under Recommendation ITU-T A.8 procedure.
+
+## **Keywords**
+
+IMT-Advanced.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 3 Definitions
+
+## 3.1 Terms defined elsewhere
+
+This Recommendation uses the following terms defined elsewhere:
+
+**3.1.1 functional entity:** [ITU-T Y.2012] An entity that comprises an indivisible set of specific functions. Functional entities are logical concepts, while groupings of functional entities are used to describe practical, physical implementations.
+
+**3.1.2 functional architecture:** [ITU-T Y.2012] A set of functional entities and the reference points between them used to describe the structure of an NGN. These functional entities are separated by reference points, and thus, they define the distribution of functions.
+
+NOTE – The functional entities can be used to describe a set of reference configurations. These reference configurations identify which reference points are visible at the boundaries of equipment implementations and between administrative domains.
+
+**3.1.3 reference point:** [ITU-T Y.2012] A conceptual point at the conjunction of two non-overlapping functional entities that can be used to identify the type of information passing between these functional entities.
+
+NOTE – A reference point may correspond to one or more physical interfaces between pieces of equipment.

+# 5 Conventions
+
+Functional entities in this Recommendation with the same name as in [ITU-T Y.2012] follow the general concept stated in [ITU-T Y.2012]; however the former is not always identical to the latter mainly because of possible additional functionalities derived as a consequence of addressing mobility. Convergence, in a precise sense, in terms of functional entities that appear in this Recommendation and in [ITU-T Y.2012] is for further study.
+
+# 6 Introduction
+
+In defining a vision for the future of mobile telecommunications, a number of layers of detail is required. The highest layer is an overall end-user service oriented perspective. This is provided in [ITU-T Q.1701] and [ITU-T Q.1702].
+
+[ITU-T Q.1703] provides the service and network capabilities and/or requirements framework, from the network aspect, for IMT-Advanced.
+
+The next level of detail is the definition of the high-level network architecture for IMT-Advanced, which includes the definition of functional entities and its relationships. This level is the objective of this Recommendation.
+
+It is expected that a future Recommendation will define how the information should flow among the functional entities in IMT-Advanced, according to the functional network architecture model adopted.
+
+# 7 General principles of the functional architecture
+
+The functional architecture incorporates the following general principles:
+
+- Network architecture based on IP technology
+
+Access networks, which provide a rich set of access mechanisms using various wired and wireless access technologies, terminate layer two link characteristics and provide IP-based connection to core networks. Core networks and application servers connected to them are IP based.
+
+- Modular construction using expandable components
+
+The subsystems themselves, such as access networks, core networks, and application servers; as well as the systems built based on them are hierarchical. In particular, core networks provide universal interfaces to different access networks and to all kinds of application servers.
+
+Accessibility to each subsystem is separately controlled based on each operator's policy; on the other hand in particular, paths that users can control to access application servers are prepared.
+
+- Open interfaces between various systems  
+Interoperation with homogeneous networks and with heterogeneous networks is facilitated with open interfaces in various levels of subsystems.
+
+# **8 Functional network architecture overview**
+
+The IMT-Advanced architecture should support multiple access networks, converged services in a converged network, enhanced security and protection, and total service accessibility, based on the services and network capabilities framework of network aspects defined in [ITU-T Q.1703] and aligned with the NGN architecture.
+
+## **8.1 NGN architecture overview**
+
+The NGN architecture is based on the general principles defined in [ITU-T Y.2011]. It is further detailed in [ITU-T Y.2012] for transport and service stratum functions and in [ITU-T M.3060] for management functions that apply to both transport and service strata.
+
+## **8.2 IMT-Advanced architecture overview and NGN**
+
+The IMT-Advanced architecture is based on the general principles defined in [ITU-T Y.2011]. It is not necessarily identical to the NGN architecture because of additional functions derived as a consequence of addressing mobility, recognizing that these two architectures are moving towards convergence.
+
+# **9 Generalized functional architecture and functional entities**
+
+This clause identifies network functions specific to IMT-Advanced and defines the corresponding network functional entities through functional models, which will form the basis for further designating reference points and developing information flows and functional entity actions.
+
+It is intended to link service and network capabilities defined in [ITU-T Q.1703] and specific to IMT-Advanced into functional entities defined in the NGN architecture, when possible.
+
+The IMT-Advanced architecture that encompasses these identified functional entities is to be understood as generalized, to allow for possible plural instantiations in more specific service or technology contexts.
+
+## **9.1 Network functions**
+
+### **9.1.1 Mobility management**
+
+The mobility management function manages mobility of terminals. In other words, it manages handover, location updating and paging for terminals. At handover and paging, the mobility management component sets routing information in entities of transport network. At location updating, the mobility management component tracks the paging area information of the terminal.
+
+Different mechanisms are applied based on the mobility management state of the terminal; i.e., location management and handover.
+
+#### **9.1.1.1 Location management**
+
+When the terminal is in idle state (i.e., it is not involved in an active session and/or radio resources for the terminal have been released), the network needs to track the location of the terminal by means of location update from the terminal. The network is able to reach the idle state terminal through the paging procedure.
+
+#### **9.1.1.2 Handover management**
+
+When the terminal is in active state (i.e., it is involved in an active session), the mobile terminal is required to be able to communicate whilst changing its point of attachment to the network due to its movement.
+
+### **9.1.2 QoS management**
+
+QoS management is meant to provide an end-to-end QoS which includes wireless and wired networks. In NGN environments, QoS management will be performed by the resource and admission control function (RACF). QoS will be based on users' preferences and/or applications. QoS management will be highly inter-related to the service control function (SCF), mobility managements and authentication, authorization and accounting (AAA).
+
+In order to efficiently meet diverse QoS requirements from the users/applications and achieve flexibility in developing QoS-enabled applications with no knowledge of the underlying transport technology and QoS mechanisms, RACF provides its QoS management service relative to a SCF in the service stratum, through which the users/applications can communicate with RACF entities to send QoS requirements, receive results and so forth.
+
+In order to provide an end-to-end QoS in the overall network interconnecting multiple access technologies and different operators' networks, RACF applies a distribution mechanism that distributes end-to-end QoS bearer specifications to each network and access system along the end-to-end path. Based on the information elements of the QoS specification, the RACF of each network and access system makes a local decision that is optimized for the local network domain.
+
+When RACF receives a QoS set up request from the SCF in the service stratum, it starts to set up QoS for the session. RACF asks mobility management to give the information for the route that a user's packet passes.
+
+Allowing differentiated QoS for different users will require the authentication and authorization of users for the requested levels of QoS, as well as accounting procedures, if the QoS is to be modified.
+
+### **9.1.3 Call session control function (CSCF)**
+
+The call session control function basically handles transactions for call/session setup, termination and forwarding to other call session control functional entities. It interacts with other network functions (mobility management, QoS management, security management, etc.) in order to support the call/session.
+
+The call session control function is realized by two functional entities, i.e., the proxy call session control functional entity (P-CSC-FE) and the serving call session control functional entity (S-CSC-FE). The P-CSC-FE acts like a proxy function to mobile terminals. The S-CSC-FE controls the call/session for the mobile terminals. It maintains a call/session state for management purposes.
+
+## **9.2 Network functional entities**
+
+### **9.2.1 Mobility management function**
+
+#### **9.2.1.1 Access router (AR)**
+
+The access router (AR) is an entity that connects a terminal to the network. This entity connects the terminal directly at the network layer.
+
+It manages the entries that contain the mapping of the terminal's network layer address to a port that connects to the corresponding AP that is associated with the terminal. Packets addressed to the terminal are forwarded by referring to the entries.
+
+It creates, updates, or deletes the entries when a RAM-FE notifies it of the AP selected by the RAM-FE.
+
+#### **9.2.1.2 Access point (AP)**
+
+The access point (AP) is an entity that connects terminals directly at the link layer to the network. It is connected to the AR.
+
+It does not terminate any network or upper layer protocol. It terminates the link layer protocol.
+
+#### **9.2.1.3 Terminal**
+
+The terminal is a device used by service subscribers to access the network.
+
+It is an entity that can connect directly to AP(s) at the link layer and to AR(s) at the network layer.
+
+It sends/receives the network control requests/responses to/from network control entities.
+
+It has two states, active and dormant, in conjunction with the routing information management in the mobility management entities.
+
+The active and dormant states are defined as follows:
+
+**Active:** The state in which the terminal is ready to send and receive packets. The transport network has the routing information of the terminal the L-MM-FE is currently serving.
+
+**Dormant:** The state where the terminal is not ready to send or receive packets. The transport network is not ready to route packets to its destination.
+
+#### **9.2.1.4 Anchor point router (APR)**
+
+The anchor point router (APR) is a router located in the L-MM-FE domain. There may be several APRs in an L-MM-FE domain.
+
+It will receive all packets on behalf of the terminals it is serving and forward them to the current address of the terminals through the ARs.
+
+This function has redundancy to avoid a single point of failure and achieve load balancing, regardless of whether or not it is distributed or centralized.
+
+Several APRs are located in the L-MM-FE domain. An APR is selected for each terminal.
+
+The APR is selected by the L-MM-FE. The selected APR is used while the terminal moves within the L-MM-FE domain.
+
+The area in which the APR does not change even if the terminal moves is defined as the APR domain.
+
+#### **9.2.1.5 Global mobility management functional entity (G-MM-FE)**
+
+The global mobility management functional entity (G-MM-FE) manages the global mobility for terminals. Global mobility is mobility between L-MM-FE domains. The G-MM-FE manages the addresses of terminals and L-MM-FE, where the terminal is located in the L-MM-FE domain. The G-MM-FE is not involved in local mobility management.
+
+It receives updated information from L-MM-FE when the L-MM-FE of a terminal changes. It stores the address of the L-MM-FE, which is used for routing information retrieval for the terminals.
+
+The G-MM-FE receives retrieval requests of routing information of a terminal from a router. The G-MM-FE forwards the request to the L-MM-FE that manages the routing information of the target terminal.
+
+It manages handover between L-MM-FE domains. It receives notifications of change of the L-MM-FE domain which is currently accessed to/from a terminal, and updates routing information for the terminal in routers, if needed. The notification comes from L-MM-FE.
+
+#### **9.2.1.6 Local mobility management functional entity (L-MM-FE)**
+
+The local mobility management functional entity (L-MM-FE) manages the local mobility for terminals. Local mobility is mobility within an L-MM-FE domain. The L-MM-FE domain is an area where the mobility related signals are controlled by the same L-MM-FE, even if the terminal moves. The FE is also involved in global mobility, which is mobility between L-MM-FE domains.
+
+The area of L-MM-FE domain is identical to that of APR domain. (Because one same APR is used while a terminal moves in the L-MM-FE domain.)
+
+It receives updated information from terminals when terminal changes paging area. It stores the paging area information, which is used for paging the terminals.
+
+The L-MM-FE receives a retrieval request from the AR and resolves the address of the G-MM-FE that manages the L-MM-FE domain of the target terminal currently located. The L-MM-FE may have the database for resolving the G-MM-FE from the address of target terminal.
+
+The L-MM-FE receives retrieval requests of routing information of a terminal from another L-MM-FE by way of the G-MM-FE. The request may trigger the paging for the terminal. From the paging, the L-MM-FE finds the routing information of the terminal, and sends the information directly to the L-MM-FE that requested the routing information of the terminal.
+
+When locating a particular terminal, the L-MM-FE can look for the appropriate RAM-FE or for multiple RAM-FEs whose addresses are in correspondence to the terminal, and request the RAM-FE or multiple RAM-FEs to page the terminal.
+
+The L-MM-FE manages the APRs and decides upon the appropriate APR when a terminal activates at paging or when initiating a communication.
+
+The L-MM-FE manages the inter-AR terminal handover within the L-MM-FE domain. It receives notifications of change of the AR that is currently connected to a terminal, and updates the routing information for the terminal in the APR and/or other routers, if needed. The notification may come from a RAM-FE or an AR.
+
+In case of intra-AR handovers, the RAM-FE only notifies the selected AP to the AR to which the terminal is connected and it does not notify any information to the L-MM-FE. Therefore, the L-MM-FE does not engage in intra-AR handover for terminals.
+
+The L-MM-FE manages addresses of terminals and RAM-FE.
+
+When the terminal moves from one L-MM-FE domain to another, the communication quality during handover and handover mechanisms should be equivalent to the case of inter-AR handover.
+
+The L-MM-FE has redundancy to avoid a single point of failure and achieve load balancing. There are several L-MM-FEs in a L-MM-FE domain.
+
+An L-MM-FE is selected when the terminal comes to a new L-MM-FE domain (i.e., active terminals perform handover from one domain to another and dormant terminals perform location registration to the new L-MM-FE domain).
+
+#### **9.2.1.7 Radio access management functional entity (RAM-FE)**
+
+The radio access management functional entity (RAM-FE) provides common interfaces to the L-MM-FE and the PD-FE.
+
+The RAM-FE receives the location update request from each radio system via control signalling in the radio systems. It sends the location update request with the addresses of terminals, the addresses of RAM-FE and location information of terminals to the L-MM-FEs via the common interface.
+
+The RAM-FE receives the paging request from the L-MM-FE and starts the paging procedure for each relevant radio system. The RAM-FE manages L3/L2 addresses of terminals and/or the addresses of radio systems. Even if the RAM-FE receives the control signal updating the location
+
+information from the RAN, the RAM-FE does not send the signalling to the L-MM-FE if that RAM-FE has already sent the same information to L-MM-FE. RAM-FEs can select the most appropriate radio system or the radio system's AP based on user's preference, QoS profile negotiated, and radio resource usage of the candidate APs when starting the paging procedure or handover, by performing (resource and QoS) coordination among the radio systems with the PD-FE.
+
+The RAM-FE can be accommodated in an AR or in multiple ARs.
+
+RAM-FE notifies the AP to the relevant entities as follows:
+
+When the RAM-FE selects the AP, the RAM-FE checks the AR that accommodates the selected AP. If the selected AP and the AP currently used are accommodated by the same AR, the RAM-FE notifies it to the AR.
+
+If the selected AP and the AP currently used are not accommodated in the same AR, the RAM-FE notifies the AR that accommodates the selected AP and notifies the new AR to PD-FE.

+
+### 9.2.2 QoS management function
+
+In the NGN environment, QoS management will be performed by resource and admission control functions (RACF). The RACF executes policy-based transport resource control upon request of the SCF, determines transport resource availability, makes admission decisions, and applies controls to transport functions for enforcing the policy decisions. The RACF consists of two types of resource and admission control functional entities: the PD-FE (policy decision functional entity) and the TRC-FE (transport resource control functional entity). This decomposition of PD-FE and TRC-FE enables the RACF to support a variety of accesses and core networks (e.g., fixed and mobile access networks).
+
+#### 9.2.2.1 Transport function
+
+The transport function executes QoS policies to the IP flows based on the end-to-end QoS specifications instructed by PD-FE. That is, it marks the QoS class for packets and allocates the bandwidth to the flow. These instructions are directly sent to each transport function by the PD-FE.
+
+If the transport function does not have enough bandwidth to receive the instruction from PD-FE, it notifies the PD-FE that it cannot guarantee the required QoS for the communication, and then the PD-FE denies the communication.
+
+#### 9.2.2.2 Policy decision functional entity (PD-FE)
+
+This function acts as an end-to-end QoS allocation function and coordination function. It is in charge of performing the negotiations with mobile terminals trying to access the network (by means of a call initiation or a handoff) or P-CSC-FE, and routers and access systems via RAM-FE to provide the resources according to the network service level policies. To identify the routers that the users' packet passes, the PD-FE inquires the user's address to mobility management functions. It is
+
+also in charge of instructing the transport function to execute QoS policies based on the result of the negotiation.
+
+If the IP flow for the user data transfer expands to another network domain, PD-FEs in different networks negotiate with each other for inter-QoS allocation.
+
+In inter-AR handover cases, the PD-FE is notified of the new AR by the RAM-FE. The PD-FE inquires the new user's address to mobility management and instructs QoS execution to transport functions.
+
+#### 9.2.2.3 Transport resource control functional entity (TRC-FE)
+
+This function deals with the diversity of underlying transport technologies and provides the resource-based admission control decision results to the PD-FE. The TRC-FE is service-independent and consists of transport technology-dependent resource control functions. The PD-FE requests the TRC-FE in the involved transport networks to detect and determine the requested QoS resources along the media flow path. The TRC-FE may collect and maintain the transport network topology and the transport resource status information, and authorize resource admission control of a transport network, based on network information.
+
+#### 9.2.2.4 Radio access management functional entity for QoS
+
+Radio access management functional entity (RAM-FE) for QoS supports an interworking function between IMT-Advanced and various access systems. It converts each access system QoS signalling to/from common QoS signalling. In this negotiation, it asks the access system (e.g., radio resource management in 3GPP RAN) to setup radio bearer based on the request from the PD-FE.
+
+![Figure 2 – Functional model for QoS management. The diagram shows a sequence of functional blocks from left to right: Mobile terminal, Access system, IMT-Advanced (containing RAM-FE, RACF, PD-FE, TRC-FE, and Transport function), IMT-Advanced (containing PD-FE, TRC-FE, and Transport function), Access system, and Correspondent terminal. Two types of connections are shown: thin lines for 'QoS signalling' and thick lines for 'User IP flows'. The Mobile terminal connects to the first Access system. The first Access system connects to the first IMT-Advanced block via both signalling and flow lines. Inside the first IMT-Advanced block, the RAM-FE connects to the RACF, which connects to the PD-FE. The PD-FE connects to the TRC-FE, which in turn connects to the Transport function. The PD-FE also connects to the second IMT-Advanced block. Inside the second IMT-Advanced block, the PD-FE connects to the TRC-FE, which connects to the Transport function. The second IMT-Advanced block connects to the second Access system. Finally, the second Access system connects to the Correspondent terminal via both signalling and flow lines.](bffdddb47fced140f8d17fdc2a29f592_img.jpg)

+
+### 9.2.3 Call session control function (CSCF)
+
+The call session control function basically handles transactions for call/session setup, termination and forwarding to other call session control functional entities. It interacts with other network functions (mobility management, QoS management, security management, etc.) in order to support the call/session.
+
+The call session control function is realized by two functional entities, i.e., the proxy call session control functional entity (P-CSC-FE) and the serving call session control functional entity (S-CSC-FE). The P-CSC-FE acts like a proxy function to mobile terminals. The S-CSC-FE controls the call/session for the mobile terminals. It maintains a call/session state for management purposes.
+
+#### 9.2.3.1 Proxy call session control functional entity (P-CSC-FE)
+
+The proxy call session control functional entity forwards call/sessions to the serving call session control functional entity from mobile terminals and vice versa. When the call/session control signalling cannot be sent to the correspondent node, the P-CSC-FE requests for mobility
+
+management to activate the terminal. When QoS is requested from the terminal, the P-CSC-FE directs QoS management to reserve the required resource.
+
+The P-CSC-FE controls the call/session for a given user. The call/session is initiated by a mobile terminal or the P-CSC-FE itself.
+
+The P-CSC-FE and the mobile terminal send and receive the call/session via the radio access management functional entity, which converts from access specific signalling to common network session signalling.
+
+The P-CSC-FE determines a change related to an active mobile terminal, and/or to the content that is being provided to that terminal and controls the changes.
+
+The P-CSC-FE holds the S-CSC-FE address, mobility management address and QoS management address for a given user.
+
+#### **9.2.3.2 Serving call session control functional entity (S-CSC-FE)**
+
+The serving call session control functional entity performs call/session control and service initiation for a given terminal.
+
+The session initiation may be authenticated and authorized by security management (e.g., HSS in 3GPP networks).
+
+When the S-CSC-FE receives call/session signals from the P-CSC-FE, it resolves the correspondent's S-CSC-FE address by inquiring mobility management, and then forwards the session signal to the correspondent's S-CSC-FE.
+
+The parties of the call/session may be identified by a string of alphabet letters, E.164 numbers or others. The S-CSC-FE may retrieve the address of the parties' mobile terminal with the identifier from directory manager.
+
+The S-CSC-FE collects the relevant data; static data (user profile, mobile terminal profile) from the global database (e.g., HSS in 3GPP systems) and dynamic data of mobile terminals (service processing status, etc.) from the mobile terminals.
+
+The S-CSC-FE may send a trigger to a media converter, when the mobile terminals in use change.
+
+The S-CSC-FE holds the P-CSC-FE address where the terminal is accommodated.
+
+#### **9.2.3.3 Global database for CSCF**
+
+Global database is a master database that manages the S-CSC-FE address of each mobile terminal. When an S-CSC-FE inquires a correspondent's S-CSC-FE address, it answers the correspondent S-CSC-FE address. When global database has no information of a mobile terminal, it returns null information, which means that the mobile terminal has not yet registered itself.
+
+#### **9.2.3.4 Radio access management functional entity for CSCF**
+
+Radio access management functional entity for the CSCF supports an interworking function between IMT-Advanced and various access systems. It converts each access system session signalling to/from common session signalling.
+
+##### **9.2.3.5 Application server (AS)**
+
+An application server (AS) offers value-added services. To this end, it interacts with the S-CSC-FE and global database. The application server may host and execute services with service logics.
+
+![Functional model for call session control function diagram showing two mobile terminals connected via access systems to a central IMT-Advanced network.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+The text is based on references [45a]-[45c].
+
+This Recommendation defines the following terms:
+
+- 3.1 authentication:** A property by which the correct identity of an entity or party is established with a required assurance. The party being authenticated could be a user, subscriber, home environment or serving network.

+- 3.6 call Detail Record (CDR):** A formatted collection of information about a chargeable event (e.g. time of call set-up, duration of the call, amount of data transferred, etc.) for use in billing and accounting. For each party to be charged for parts of, or all charges of, a chargeable event, a separate CDR shall be generated, i.e. more than one CDR may be generated for a single chargeable event, e.g. because of its long duration, or because more than one charged party is to be charged.
+- 3.7 charging:** A function whereby information related to a chargeable event is formatted and transferred in order to make it possible to determine usage for which the charged party may be billed.
+- 3.8 cipher key:** A code used in conjunction with a security algorithm to encode and decode user and/or signalling data.
+
+- 3.9 closed user group:** A group with a predefined set of members. Only defined members may participate in a closed user group.
+- 3.10 handover:** The transfer of a user's connection from one radio channel to another (can be the same or different cell).

+- 3.20 MExE service:** A service enhanced (or made possible) by MExE technology.
+- 3.21 MExE service environment:** Depending on the configuration of the PLMN, the operator may be able to offer support to MExE services in various ways. Examples of possible sources are from traditional GSM nodes, IN nodes, operator specific nodes, operator franchised nodes and services provider nodes, together with access to nodes external (i.e. vendor-specific) to the PLMN depending on the nature of the MExE service. These nodes are considered to constitute the MExE service environment. The MExE service environment shall support direct MExE UE to MExE UE interaction of MExE services.
+- 3.22 mobile number portability:** The ability for a mobile subscriber to change subscription network within the same country whilst retaining their original MSISDN(s).
+- 3.23 Mobile Station (MS):** See user equipment.
+- 3.24 multimedia service:** Services that handle several types of media such as audio and video in a synchronized way from the user's point of view. A multimedia service may involve multiple parties, multiple connections, and the addition or deletion of resources and users within a single communication session.
+- 3.25 open service architecture:** Concept for introducing a vendor independent means for introduction of new services.
+- 3.26 OSA interface:** Standardized Interface used by application/clients to access service capability features.
+- 3.27 performance:** The ability to track service and resource usage levels and to provide feedback on the responsiveness and reliability of the network.
+
+**3.28 PLMN area:** The PLMN area is the geographical area in which a PLMN provides communication services according to the specifications to mobile users. In the PLMN area, the mobile user can set up calls to a user of a terminating network. The terminating network may be a fixed network, the same PLMN, another PLMN or other types of PLMN. Terminating network users can also set up calls to the PLMN. The PLMN area is allocated to a PLMN. It is determined by the service and network provider in accordance with any provisions laid down under national law. In general the PLMN area is restricted to one country. It can also be determined differently, depending on the different telecommunication services, or type of MS. If there are several PLMNs in one country, their PLMN areas may overlap. In border areas, the PLMN areas of different countries may overlap. Administrations will have to take precautions to ensure that border coverage is minimised in adjacent countries unless otherwise agreed.
+
+**3.29 public land mobile network:** A telecommunications network providing mobile cellular services.
+
+**3.30 quality of service:** The collective effect of service performance which determine the degree of satisfaction of a user of a service. It is characterised by the combined aspects of performance factors applicable to all services, such as;
+
+- Service operability performance;
+- Service accessibility performance;
+- Service retain ability performance;
+- Service integrity performance; and
+- Other factors specific to each service.
+
+**3.31 roaming:** The ability for a user to function in a serving network different from the home network.

+
+**3.37 supplementary service:** A service which modifies or supplements a basic telecommunication service. Consequently, it cannot be offered to a user as a standalone service. It must be offered together with or in association with a basic telecommunication service. The same supplementary service may be common to a number of basic telecommunication services.
+
+**3.38 telecommunication service:** That which is offered by a PLMN operator or service provider to its customers in order to satisfy a specific telecommunication requirement. Telecommunication services are divided into two broad families: bearer services and teleservices.
+
+**3.39 teleservice:** Is a type of telecommunication service that provides the complete capability, including terminal equipment functions, for communication between users according to standardized protocols and transmission capabilities established by agreement between operators.
+
+**3.40 Universal Mobile Telecommunications System (UMTS):** The telecommunications system, incorporating mobile cellular and other functionality, that is the subject of standards
+
+produced by Standardization Development Organization, that constitutes the 3G Partnership Project.

+
+**3.43 user equipment:** A device allowing a user access to network services. For the purpose of 3GPP specifications the interface between the UE and the network is the radio interface. A User Equipment can be subdivided into a number of domains, the domains being separated by reference points. Currently defined domains are the USIM and ME Domains. The ME Domain can further be subdivided into several components showing the connectivity between multiple functional groups. These groups can be implemented in one or more hardware devices. An example of such a connectivity is the TE-MT interface. Further, an occurrence of a User Equipment is an MS for GSM as defined TS 24.002.
+
+**3.44 virtual home environment:** A concept for personal service environment portability across network boundaries and between terminals.

+# 5 Introduction
+
+The core network for this IMT-2000 family member referred to as "UMTS", is based on an evolved core network from the 2nd generation mobile system, GSM. The technical specifications have been developed in a partnership project and transposed to the involved Standards Development Organizations (SDOs). The system will support different applications ranging from narrow-band to wide-band communications capability with integrated personal and terminal mobility to meet the user and service requirements.
+
+Release 1999 is the first release of this 3rd generation of mobile communications technology. The core network interfaces identified in this Recommendation constitute a complete mobile core network system for terrestrial usage based on GSM evolved UMTS core network with UTRAN access network
+
+Refer to 10.2.37 "UMTS Service principles" for more information.
+
+The description of the Technical Specifications listed in Clause 10 are for informative purposes only. Normative information is in the tables.
+
+# 6 Basic architecture for the UMTS IMT-2000 family member
+
+This text is based on references [2a]-[2e] section 5.1.
+
+The basic configuration of a Public Land Mobile Network (PLMN) supporting GPRS and the interconnection to the PSTN/ISDN and PDN is presented in Figure 6-1. This configuration presents signalling interfaces, which can be found in a PLMN. Implementations may be different: some particular functions may be gathered in the same equipment and then some interfaces may become internal interfaces.
+
+In the basic configuration presented in Figure 6-1, all the functions are considered implemented in different equipments. Therefore, all the interfaces within PLMN are external. This Recommendation will only describe the internal interfaces in the Core Network (CN) and the external interfaces to and from CN. Interfaces Iu, Iur and Iubis are defined in the UMTS 25.4xx-series of Technical Specifications, which are outside the scope of this Recommendation. Interfaces C, D, E, F and G need the support of the Mobile Application Part of the Signalling System No. 7 to exchange the data necessary to provide the mobile service. No protocols for the H-interface and for the I-interface are standardized. All the GPRS-specific interfaces (G series) are defined in the UMTS 23- and 24-series of Technical Specifications.
+
+From this configuration, all the possible PLMN organizations can be deduced. In the case when some functions are contained in the same equipment, the relevant interfaces become internal to that equipment.
+
+![Diagram of a PLMN supporting CS and PS services and interfaces. The diagram shows the internal components of a Core Network (CN) and its interfaces to external and internal networks. CN components include GMSC, GGSN, HLR, EIR, MSC/VLR, and SGSN. External interfaces include PSTN (via GMSC), Gi (to GGSN), and Gp (to GGSN). Internal interfaces include C (GMSC-HLR), H (AuC-HLR), Gc (GGSN-HLR), Gn (GGSN-SGSN), Gr (HLR-SGSN), D (MSC/VLR-HLR), F (MSC/VLR-EIR), Gf (EIR-SGSN), Gs (MSC/VLR-SGSN), G (MSC/VLR-external MSC/VLR), and E (MSC/VLR-external MSC/VLR). The Radio Network Subsystem (RNS) contains an RNC connected to the CN via IuCS (to MSC/VLR) and IuPS (to SGSN). The RNC is also connected to another RNC via Iur and to two Node B cells via Iubis. Each Node B contains three cells. The User Equipment (UE) consists of a Mobile Equipment (ME) and a USIM connected via Cu. The ME connects to the Node B cells via the Uu interface. Bold lines represent user traffic interfaces, and dashed lines represent signalling interfaces.](e69b9188aa2c14ec6b21c83f711fef65_img.jpg)

+
+Gateway Location Register (GLR) is an optional functional entity to optimize signalling traffic between PLMNs. This entity handles location management of roaming subscriber in visited network without involving HLR. The location register function in the GLR stores subscription information and routing information for both CS services and PS services. This entity can be only located in a visited PLMN.
+
+In the basic configuration with GLR introduction, presented in Figure 6-5, all the functions related to GLR introduction is considered implemented in different equipments. Therefore, all the interfaces within PLMN are external. Interfaces GLa, GLb, GLc, GLd, GLf, GLg, GLh, and GLi need the support of the Mobile Application Part of the signalling system No. 7 to exchange the data necessary to provide the mobile service. No protocols for the GLe interface are standardized. GLj and GLk need the support of GPRS Tunnelling Protocol – Control to provide the packet domain services.

+The diagram illustrates the network architecture and interfaces within a PLMN. At the top, SGSN and VLR/MSC are shown. SGSN connects to IM-GSN via GLk (user traffic) and GLc (signalling). VLR/MSC connects to IM-SC via GLh (user traffic) and GLb (signalling). IM-GSN connects to GLR via GLe (signalling) and GLj (user traffic). IM-SC connects to GLR via GLd (signalling) and GLg (user traffic). GLR connects to GGSN via GLa (signalling), to HLR via GLf (signalling), and to SMS-GMSC via GLi (signalling). All these entities (GGSN, HLR, SMS-GMSC, GMLC) are part of the 'Other PLMN'. A legend at the bottom left defines the line types: dotted for signalling and solid for user traffic, noting that user traffic includes Short Messages. The diagram is identified by Q.1741.1 F06-5 in the bottom right.

+## 7.1 Gateway Mobile Switching Centre (GMSC)
+
+The text in this clause is based on references [2a]-[2e] section 4.1.2.2.
+
+The Mobile Switching Center (MSC), which performs the routing function to the actual location of the Mobile Station (MS), is called the Gateway MSC (GMSC).
+
+If a network delivering a call to the PLMN cannot interrogate the Home Location Register (HLR), the call is routed to an MSC. This MSC will interrogate the appropriate HLR and then route the call to the MSC where the mobile station is located.
+
+The acceptance of an interrogation to an HLR is the decision of the operator.
+

+## 7.2 Mobile Switching Centre and Visitor Location Register MSC/VLR (MSC/VLR)
+
+### 7.2.1 Mobile Switching Centre (MSC)
+
+The text in this clause is based on references [2a]-[2e] section 4.1.2.1.
+
+The Mobile-services Switching Centre (MSC) constitutes the interface between the radio system and the fixed networks. The MSC performs all necessary functions in order to handle the circuit-switched services to and from the mobile stations.
+
+In order to obtain radio coverage of a given geographical area, a number of base stations are normally required; i.e. each MSC would thus have to interface several base stations. In addition, several MSCs may be required to cover a country.
+
+The Mobile-services Switching Centre is an exchange that performs all the switching and signalling functions for mobile stations located in a geographical area designated as the MSC area. The main difference between a MSC and an exchange in a fixed network is that the MSC has to take into account the impact of the allocation of radio resources and the mobile nature of the subscribers and has to perform in addition, at least the following procedures:
+
+- Procedures required for the location registration;
+- Procedures required for handover.
+
+### 7.2.2 Visitor Location Register (VLR)
+
+The text in this clause is based on references [2a]-[2e] section 4.1.1.2.
+
+A mobile station roaming in an MSC area is controlled by the Visitor Location Register in charge of this area. When a Mobile Station (MS) enters a new location area it starts a registration procedure. The MSC in charge of that area notices this registration and transfers to the Visitor Location Register the identity of the location area where the MS is situated. If this MS is not yet registered, the VLR and the HLR exchange information to allow the proper handling of calls involving the MS.
+
+A VLR may be in charge of one or several MSC areas.
+
+The VLR also contains the information needed to handle the calls set up or received by the MSs registered in its data base (for some supplementary services, the VLR may have to obtain additional information from the HLR). The following elements are included:
+
+- The International Mobile Station Identity (IMSI);
+- The Mobile Station International ISDN number (MSISDN);
+- The Mobile Station Roaming Number (MSRN),
+- The Temporary Mobile Station Identity (TMSI), if applicable;
+- The Local Mobile Station Identity (LMSI), if used;
+- The location area where the mobile station has been registered;
+- The identity of the SGSN where the MS has been registered. Only applicable to PLMNs supporting GPRS and which have a Gs interface between MSC/VLR and SGSN;

The following kinds of information are stored there:
+
+- The subscription information;
+- Some location information enabling the charging and routing of calls towards the MSC where the MS is registered (e.g. the MS Roaming Number, the VLR Number, the MSC Number, the Local MS Identity);
+
+and, if GPRS is supported, also:
+
+- Location information enabling the charging and routing of messages in the SGSN where the MS is currently registered (e.g. the SGSN Number);
+
+and, if LCS is supported, also:
+
+- A LCS privacy exception list, which indicates the privacy class of the MS subscriber;
+- A GMLC list;
+- A MO-LR list.
+
+Different types of identity are attached to each mobile subscription and are stored in the HLR. The following identities are stored:
+
+- The International Mobile Station Identity (IMSI);
+- One or more Mobile Station International ISDN number(s) (MSISDN);
+
+If GPRS is supported, the following identity is also stored:
+
+- Zero or more Packet Data Protocol (PDP) address(es);
+
+and, if LCS is supported, the following identity is also stored:
+
+- The LMU indicator.
+
+There is always at least one identity, apart from the IMSI, attached to each mobile subscription and stored in the HLR.
+
+The IMSI or the MSISDN may be used as a key to access the information in the database for a mobile subscription.
+
+The database contains other information such as:
+
+- Teleservices and bearer services subscription information;
+- Service restrictions (e.g. roaming limitation);
+- A list of all the group IDs a service subscriber is entitled to use to establish voice group or broadcast calls;
+- Supplementary services; the HLR contains the parameters attached to these services;
+
+and, if GPRS is supported, also:
+
+- Information about if a GGSN is allowed to dynamically allocate PDP addresses for a subscriber.
+
+## 7.4 Authentication Centre (AuC)
+

+
+The Authentication Centre (AuC) is an entity that stores data for each mobile subscriber to allow the International Mobile Subscriber Identity (IMSI) to be authenticated and to allow communication over the radio path between the mobile station and the network to be ciphered. The AuC transmits the data needed for authentication and ciphering via the HLR to the VLR, MSC and SGSN which need to authenticate a mobile station.
+
+The Authentication Centre (AuC) is associated with an HLR, and stores an identity key for each mobile subscriber registered with the associated HLR. This key is used to generate:
+
+- Data that are used to authenticate the International Mobile Subscriber Identity (IMSI);
+- A key used to cipher communication over the radio path between the mobile station and the network.
+
+The AuC communicates only with its associated HLR over an interface denoted the H-interface (see 8.28).

+
+The text in this clause is based on the text in references [2a]-[2e] section 6.4.1.3.
+
+This interface is used to exchange the data related to the location of the mobile station and to the management of the subscriber. The main service provided to the mobile subscriber is the capability to set up or to receive calls within the whole service area. To support this, the location registers have to exchange data. The VLR informs the HLR of the location of a mobile station managed by the latter and provides it (either at location updating or at call set-up) with the roaming number of that station. The HLR sends to the VLR all the data needed to support the service to the mobile subscriber. The HLR then instructs the previous VLR to cancel the location registration of this subscriber. Exchanges of data may occur when the mobile subscriber requires a particular service, when he wants to change some data attached to his subscription or when some parameters of the subscription are modified by administrative means.
+
+Signalling on this interface uses the Mobile Application Part (MAP), which in turn uses the services of Transaction Capabilities.
+
+For Customized Applications for Mobile network Enhanced Logic (CAMEL) purposes, this interface is used to send the CAMEL related subscriber data to the visited PLMN and for provision of MSRN.

+
+# **9 Technical specifications structure**
+
+This clause provides an overview of the specifications for this IMT-2000 Family member based on GSM evolved UMTS core Network with UTRAN access network. Details for these specifications may be found in clause 10.
+
+The following text describes the numbering scheme for the specifications and reports for the 3GPP 3rd Generation Mobile System.
+
+Specifications for Release 1999 of the 3rd Generation mobile system are identified by the "ab.cde" numbering scheme.
+
+Where existing GSM Specifications are enhanced or modified by the TSGs for the 3rd Generation Mobile System, the specification title and version should change (title reflecting 3rd Generation Mobile System). The GSM number (ab) has increased by 20 and a "c" digit equal to zero added (e.g., GSM 07.07 becomes 3GTS 27.007) indicating the GSM heritage of the Specification. Table 1 is a conversion table between specifications on the second generation GSM system and specifications in the third generation UMTS system.
+
+For newly created 3GPP Specifications the "c" digit is not zero.
+
+The following Series titles and descriptions are used for guidance only and may be further developed with experience.
+
+The specification series are:

+### 10.1.3 TS 21.133 Security threats and requirements
+
+This specification takes notice of the Security Principles and Objectives as set out in TS 33.120. It contains an evaluation of perceived threats to 3GPP and subsequently produces a list of security requirements to address these threats.
+
+As teleservices and applications will not, in general, be standardized, it is difficult to predict their exact nature. Therefore, this specification considers all security threats and aims at listing generic security requirements that shall be applicable, irrespective of the actual services offered. The list of threats and requirements may, however, need to be updated as the 3GPP system evolves.
+
+The threat analysis performed relies to a large extent on previous experiences with 2G systems, in particular GSM, and takes into account known problems from that area.
+
+The security requirements listed in this specification shall be used as input for the choice of security features and the design of the 3GPP security architecture as specified in TS 33.102.

+### 10.2.8 TS 22.024 Description of Charge Advice Information (CAI)
+
+The charging supplementary service is described in TS 22.086. These services are designed to supply to a mobile user sufficient information to allow a real-time estimate to be made of the bill, which will eventually be levied in the home PLMN on the Mobile Station (MS) subscriber.
+
+In the case of certain MS uses, for example a mobile payphone, this estimate could be subject to further processing (e.g. to present the charges in currency, rather than units, this may include an additional mark up). This additional processing is not described in this document in order to avoid constraining the evolution of the MS product in this area.
+
+This document gives an overall view of how this supplementary service shall operate both in the PLMN and within the MS. Text given in this document is required to define functionality and is not intended to constrain implementation.

+
+This Technical Specification defines the stage one description of the Support of Mobile Number Portability between networks in the same country as well as North America cross-sector portability (i.e., number portability between fixed and GSM mobile networks). Stage one is an overall service description, primarily from the service subscriber's and user's points of view, but does not deal with the details of the human interface itself.
+
+Mobile Number Portability (MNP) is applicable only to those telecommunication services identified by an MSISDN.
+
+This specification includes information applicable to network operators, service providers and terminal, switch and database manufacturers.
+
+This specification contains the core requirements for the Support of Mobile Number Portability between network operators in the same country as well as North America cross-sector portability, which are sufficient to provide a complete service.
+
+Other cross-sector portability options (e.g. number portability between fixed and mobile networks outside the North American Region) are outside the scope of this technical specification. It is highly desirable however, that technical solutions for MNP should be sufficiently flexible to allow for possible enhancements, e.g. cross-sector number portability, and MNP between analogue and digital mobile networks. Additional functionalities not documented in this specification may implement requirements, which are considered outside the scope of this specification. This additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional functionality shall not compromise conformance to the core requirements of the service.
+
+Porting between Service Providers (i.e. service provider portability), which does not involve a change of Network Operator is outside the scope of this specification.
+
+The relationship between Service Providers and Network Operators is outside the scope of this specification.
+
+The relationship between a Service Provider and subscriber is outside the scope of this specification. The interface between the Mobile Station (MS) and any external applications are outside the scope of this specification.

+### 10.2.17 TS 22.067 Enhanced Multi-Level Precedence and Preemption service (eMLPP); Stage 1
+
+The document specifies the stage 1 description of the enhanced Multi-Level Precedence and Preemption Service (eMLPP). This service has two parts: precedence and preemption. Precedence involves assigning a priority level to a call in combination with fast call set-up. Preemption involves the seizing of resources, which are in use by a call of a lower precedence, by a higher-level precedence call in the absence of idle resources. Preemption can also involve the disconnection of an on-going call of lower precedence to accept an incoming call of higher precedence.
+
+The eMLPP service is provided as a network operator's option to a domain of a network. The domain can be the whole network or a subset of the network. The eMLPP service applies to all network resources in the domain that is in common use. The eMLPP service is applicable to all mobile stations in the domain with all or some mobile stations having a respective subscription assigning precedence according to the eMLPP service.
+
+eMLPP is a supplementary service and shall be provided to a subscriber for all basic services subscribed to and for which eMLPP applies.
+
+NOTE – It is under study whether normal GSM Phase 2 Mobile Stations will be able to be used for this service.
+
+The service is described from the service subscriber's and user's point of view, in particular:
+
+- The procedure for normal operation with successful outcome;
+- The action to be taken in exceptional circumstances;
+- The interaction with other services and features.
+
+The document does not deal with the Man-Machine Interface (MMI) requirements, but makes reference to the appropriate specifications.
+
+The document is applicable to teleservices 1x and 6x and to all bearer services used in a mobile network if eMLPP is provided. Any interaction with other services and/or networks not dealt with in clauses 8 or 9 is outside the scope of the present document.

+### 10.2.18 TS 22.071 Location Services (LCS); Stage 1 (T1P1)
+
+The document provides the Stage One description of Location Services (LCS) networks. A stage one description provides an overall service description, primarily from the service subscriber's and user's points of view, but not dealing with the details of the Man Machine Interface (MMI). This Technical Specification includes information applicable to network operators, service providers and terminal, base station system, switch and data base manufacturers.
+
+NOTE – Location Services may be considered as a network provided enabling technology consisting of standardized service capabilities, which enables the provision of location applications. This application may be service provider specific. The description of the numerous and varied possible location applications which are enabled by this technology are outside the scope of this specification. However, clarifying examples of how the functionality being specified may be used to provide specific location services is included in various sections of the specification.
+
+The document contains the core requirements for the LCS to an extent sufficient to derive a complete definition of the LCS at the service level. However, the present document also documents some additional requirements, which may suggest, in a non-normative manner, certain ways the system may be implemented to support the LCS feature.
+
+LCS can be offered without subscription to basic telecommunication services. LCS is available to the following categories of LCS clients:
+
+Value Added Services LCS Clients – use LCS to support various value added services. These clients can include MS subscribers as well as non-subscribers to other services.
+
+PLMN Operator LCS Clients – use LCS to enhance or support certain O&M related tasks, supplementary services, IN related services and bearer services and teleservices.
+
+Emergency Services LCS Clients – use LCS to enhance support for emergency calls from subscribers.
+
+Lawful Intercept LCS Clients – use LCS to support various legally required or sanctioned services.
+
+LCS is applicable to any target MS whether or not the MS supports LCS, but with restrictions on choice of positioning method or notification of a location request to the MS user when LCS or individual positioning methods, respectively, are not supported by the MS.
+
+LCS will be developed in phases. Phase 1 includes provision of the following:
+
+LCS Phase 1. This is the initial default phase of LCS. It provides a generic flexible architecture capable of supporting all positioning methods. Specific support is provided for Time Of Arrival (TOA), Enhanced Observed Time Difference (E-OTD) and Global Positioning System (GPS) based positioning methods. Support is provided for emergency services, value added services and PLMN operator services.

+### 10.2.20 TS 22.078 CAMEL; Stage 1
+
+This standard specifies the stage 1 description for the Customized Applications for Mobile network Enhanced Logic (CAMEL) feature, which provides the mechanisms to support services consistently independently of the serving network. The CAMEL features shall facilitate service control of operator specific services external from the serving PLMN. The CAMEL feature is a network feature and not a supplementary service. It is a tool to help the network operator to provide the subscribers with the operator specific services even when roaming outside the HPLMN.
+
+CAMEL is developed in phases.
+
+- CAMEL phase 1. This is the default phase in this specification.
+- CAMEL phase 2.
+- CAMEL phase 3.
+
+A VPLMN or IPLMN supporting CAMEL phase 2 shall also support CAMEL phase 1.
+
+The CAMEL feature is applicable
+
+- To mobile originated and mobile terminated call related activities;
+- As a CAMEL phase 2 function, to supplementary service invocations;
+
+- As a CAMEL Phase 3 function, to SMS MO, to GPRS sessions and PDP contexts, to the control of HLR subscriber data, to the control of network signalling load.
+
+The mechanism described addresses especially the need for information exchange among the VPLMN, HPLMN and the CAMEL Service Environment (CSE) for support of such operator specific services. Any user procedures for operator specific services are outside the scope of this standard.
+
+This specification describes the interactions between the functions of the VPLMN, HPLMN, IPLMN and the CSE.
+
+The second phase of CAMEL enhances the capabilities of phase 1. The following capabilities are added:
+
+- Additional event detection points;
+- Interaction between a user and service using announcements, voice prompting and information collection via in band interaction or USSD interaction;
+- Control of call duration and transfer of Advice of Charge Information to the mobile station;
+- The CSE can be informed about the invocation of the supplementary services ECT, CD and MPTY;
+- For easier post-processing, charging information from a serving node can be integrated in normal call records.
+
+The third phase of CAMEL enhances the capabilities of phase 2. The following capabilities are added:
+
+- Support of facilities to avoid overload;
+- Capabilities to support Dialled Services;
+- Capabilities to handle mobility events, such as (Not-) reach ability and roaming;

+### 10.2.21 TS 22.079 Support of Optimal Routing (SOR); Stage 1
+
+This stage 1 description of the first phase of Support of Optimal Routing (SOR):
+
+- Compiles the basic service requirements for SOR;
+- Describes the interactions for Supplementary Services (SS) in order to cater for SOR;
+- Refers to modifications to network features required by SOR.
+
+This specification does not address the following:
+
+- There is no need for optimization of the routing of calls originally directed to a fixed network subscriber, because the physical address of a fixed network terminating line cannot differ from its logical address.
+- SOR in non-PLMNs is not a subject of this Technical Specification, but might be possible by bilateral arrangement between PLMN operators and those non-PLMN operators.
+
+The purpose of SOR is to reduce the number of unnecessary inter-PLMN call legs.
+
+The first phase of SOR applies to:
+
+- Optimal Routing for the benefit of the B party i.e. Mobile terminated calls with late call forwarding to the home or visited country (scenarios 1 and 2), and optionally;
+- Optimal Routing for the benefit of the A party, e.g. Mobile to mobile calls where both mobile subscribers are in the same country (scenarios 3 to 10).
+
+The complete set of scenarios included in the phase 1 of Optimal Routing is presented in the paragraph for normal procedures. All other scenarios are excluded from Phase 1 of Optimal Routing.
+
+Note that Optimal Routing is applicable to national roaming situations that are to calls directed to a mobile subscriber roaming in her home country, but registered in a PLMN different from her HPLMN.
+
+All further call scenarios, including multiple call forwarding, are left to subsequent phases of SOR. Subsequent phases of SOR shall be backwards compatible with this first phase.

+### 10.2.22 TS 22.081 Line identification supplementary services; Stage 1
+
+The document describes the Supplementary Services belonging to the group Line Identification Supplementary Services.
+
+The general aspects, including definitions and recommended provision, of the description of the Supplementary Services are given in TS 22.004.
+
+The group of Line Identification Supplementary Services is divided into the following four Supplementary Services:
+
+- CLIP – Calling line identification presentation;
+- CLIR – Calling line identification restriction;
+- COLP – Connected line identification presentation;
+- COLR – Connected line identification restriction.
+
+**Definition of line identity:** The line identity is made up of a number of information units:
+
+- The subscriber's national ISDN/MSISDN number (MSISDN number is the number stored in the VLR);
+- The country code;
+- Optionally, subaddress information. The PLMN cannot be responsible for the content of this subaddress. (For definition of the subaddress see 11.2/E.164 [10].
+
+In a full ISDN environment, the line identity shall include all the address information necessary to unambiguously identify a subscriber.
+
+The calling line identity is the line identity of the calling party.
+
+The connected line identity is the line identity of the connected party.
+
+If, for the line identity of the calling party or the connected party, additional line identification is received (additional calling party/connected party number) in a PLMN, this additional line identification shall be used for the presentation purpose of the line identification presentation services.
+
+**Definition of Presentation and Screening Indicators:** In addition to, or instead of, the line identity, the network may give a Presentation Indicator (PI) and/or a Screening Indicator (SI) to the served subscriber. The following information may be given:
+
+- Presentation Indicator showing:
+  - a) Presentation allowed; or
+  - b) Presentation restricted; or
+  - c) Number not available due to interworking.
+
+If Presentation Indicator is set to "Presentation Restricted", then the MS can get additional information on the Cause of no CLI, if provided by the network.
+
+The Cause of no CLI value may be one of the following:
+
+- Unavailable;
+- Reject by user;
+- Interaction with other services;
+- Coin line / pay phone;
+- Screening Indicator showing:
+  - a) User provided, verified and passed; or
+  - b) User provided, not screened; or
+  - c) Network provided.
+
+If the line identity is that of a PLMN subscriber, then:
+
+- The national number and the country code shall always be provided by the network;
+- The subaddress shall only be included if it is provided by the user (or user equipment);
+- The screening indicator shall indicate "network provided".

+
+### 10.2.23 TS 22.082 Call Forwarding (CF) supplementary services; Stage 1
+
+This specification describes the supplementary services belonging to the group call offering supplementary services.
+
+The general aspects, including definitions and recommended provision, of the description of the supplementary services are given in specification TS 22.004.
+
+The group of supplementary services call offering supplementary services is divided into four different supplementary services:
+
+- Call forwarding unconditional;
+- Call forwarding on mobile subscriber busy;
+- Call forwarding on no reply;
+- Call forwarding on mobile subscriber not reachable.
+
+#### Indication of active Call forwarding supplementary service
+
+An indication that a Call forwarding service is currently active and operative on a number will be given to the forwarding party each time an outgoing call is made. There will be one indication for Unconditional call forwarding and another common indication for the Conditional call forwarding services.
+
+##### Note on the use of the forwarded-to number at registration
+
+If the forwarded-to number is a number in the HPLMN country, it may be entered by the served mobile subscriber in three different formats, independent of her actual location, according to the schemes:
+
+- 1) National (significant) number;
+- 2) National (trunk) prefix plus national (significant) number;
+- 3) International prefix (see Note), country code, national (significant) number.
+
+Scheme 3) Storage of numbers in this format is mandatory for all PLMN operators.
+
+If the forwarded-to number is a number in a country other than the HPLMN country, it shall be entered by the served mobile subscriber, independent of her actual location, according to the following scheme:
+
+- International prefix (see Note), country code, national (significant) number.
+
+NOTE – The MMI for entering of international prefix is defined in TS 22.030.
+
+The maximum forwarded-to number length is 28 digits.
+
+#### **Principles for interaction with the Barring of Outgoing Calls supplementary services**
+
+Numbers allowed to call according to the Barring of Outgoing call service condition are allowed as forwarded-to numbers for the served mobile subscriber.
+
+Numbers not allowed to call according to the Barring of Outgoing call service condition are not allowed as forwarded-to numbers for the served mobile subscriber.
+
+For Unconditional Call Forwarding the forwarded leg is treated as an outgoing call from the HPLMN country.
+
+For the Conditional Call Forwarding services the forwarded leg is treated as an outgoing call from the LPLMN (HPLMN or VPLMN) country.
+
+#### **Principles for interaction with the Barring of Incoming Calls supplementary services**
+
+When Barring of all incoming calls is active for the served mobile subscriber, no Call forwarding services are allowed for her.
+
+When Barring of all incoming calls when roaming outside the HPLMN country is active and operative, i.e. the served mobile subscriber is roaming outside the HPLMN country, the Conditional Call Forwarding services are not allowed.

+### 10.2.27 TS 22.086 Advice of Charge (AoC) supplementary services; Stage 1
+
+The document describes the supplementary services belonging to the group Charging Supplementary Services.
+
+The general aspects, including definitions and recommended provision, of the description of the supplementary services are given in TS 22.004.
+
+Charging services are the supplementary services associated with charging aspects. The group of supplementary services Charging Supplementary Services comprises two services:
+
+- Advice of Charge (Information);
+- Advice of Charge (Charging).
+
+Advice of Charge (AoC) supplementary services will use the Charge Advice Information described in TS 22.024.
+
+In principle, the same type of Mobile Station (MS) can be used for both services of Advice of Charge (AoC), except where the application demands special features – e.g. the payment mechanism in a payphone.
+
+Only one of these services may be subscribed to at any one time.

+### 10.2.29 TS 22.088 Call Barring (CB) supplementary services; Stage 1
+
+The document describes the supplementary services belonging to the group Call Restriction Supplementary Services.
+
+The general aspects, including definitions and recommended provision, of the description of the supplementary services are given in TS 22.004.
+
+The Call Restriction supplementary services allow the possibility for a mobile subscriber to have barring of certain categories of outgoing or incoming calls at the mobile subscribers access.
+
+The group of Call Restriction Services includes two supplementary services:
+
+- Barring of outgoing calls;
+- Barring of incoming calls.
+
+By use of subscription options, the mobile subscriber can, at provision time, select a set of one or more barring programs to determine the categories of calls to be barred. The following categories are defined:
+
+- All outgoing calls;
+- Outgoing international calls;
+- Outgoing international calls except those directed to the home PLMN country;
+- All incoming calls;
+- Incoming calls when roaming outside the home PLMN country.
+
+NOTE 1 – Each category (barring program) is handled as a single supplementary service.
+
+NOTE 2 – The call barring program "incoming calls when roaming outside the home PLMN country" is only relevant if as a general rule the called mobile subscriber pays the charges for the forwarded part of the call from his home PLMN country to any other country.
+
+The barring services can be offered to a mobile subscriber with a password option allowing the activation and deactivation by the subscriber. One password per mobile subscriber is supported by the network for all barring services. For the definition of the password, the description of its use and its management, see TS 22.004.

+### 10.2.37 TS 22.101 UMTS Service principles
+
+This Technical Specification (TS) describes the Service principles for PLMNs specified by 3GPP.
+
+3GPP specifications provide integrated personal communications services. The system will support different applications ranging from narrow-band to wide-band communications capability with integrated personal and terminal mobility to meet the user and service requirements of the 21st century.
+
+3GPP specifications allow the realization of a new generation of mobile communications technology for a world in which personal communications services should allow person-to-person calling, independent of location, the terminal used, the means of transmission (wired or wireless) and the choice of technology. Personal communication services should be based on a combination of fixed and wireless/mobile services to form a seamless end-to-end service for the user.
+
+3GPP specifications should be in compliance with the following objectives:
+
+- To provide a single integrated system in which the user can access services in an easy to use and uniform way in all environments;
+- To allow differentiation between service offerings of various serving networks and home environments;
+- To provide a wide range of telecommunications services including those provided by fixed networks and requiring user bit rates of up to 2 Mbits/s as well as services special to mobile communications. These services should be supported in residential, public and office environments and in areas of diverse population densities. These services are provided with a quality comparable with that provided by fixed networks such as ISDN;
+- To provide services via hand-held, portable, vehicular mounted, movable and fixed terminals (including those which normally operate connected to fixed networks), in all environments (in different service environments i.e. residential, private domestic and different radio environments) provided that the terminal has the necessary capabilities;
+- To provide support of roaming users by enabling users to access services provided by their home environment in the same way even when roaming.
+- To provide audio, data, video and particularly multimedia services;
+- To provide for the flexible introduction of telecommunication services;
+
+- h) To provide within the residential environment the capability to enable a pedestrian user to access all services normally provided by fixed networks;
+- i) To provide within the office environment the capability to enable a pedestrian user to access all services normally provided by PBXs and LANs;
+- j) To provide a substitute for fixed networks in areas of diverse population densities, under conditions approved by the appropriate national or regional regulatory authority.
+- k) To provide support for interfaces, which allow the use of terminals normally, connected to fixed networks.

+
+The document specifies the content of the stage one requirement for realization of VHE.
+
+Virtual Home Environment (VHE) is defined as a concept for personal service environment (PSE) portability across network boundaries and between terminals. The concept of the VHE is such that users are consistently presented with the same personalized features, User Interface customization and services in whatever network and whatever terminal (within the capabilities of the terminal and the network), wherever the user may be located.
+
+A key feature to support VHE is the ability to build services using a standardized application interface.
+
+Requirements not applicable for R99 will be explicitly indicated.

+### 10.2.41 TS 22.129 Handover requirements between UMTS and GSM or other radio systems
+
+The scope of this document includes service requirements for handover maintaining continuity of service to a wireless terminal as it moves between the radio coverage area, or "cells", associated with different base station sites. This functionality is called "handover". Handover can also occur due to change of radio resource providing a service without necessarily any change of the base stations involved. In particular, when the radio resources providing a service change from one of the UTRA radio access modes to the other (UTRA-FDD and UTRA-TDD), this is regarded as handover. Particular emphasis has been placed on the description of requirements for service continuity within UTRAN and between UTRAN and GERAN but requirements specific to other systems are incorporated as required.
+
+It is a key requirement to allow for dual or multi-mode terminals to hand over traffic from UTRAN to other radio systems such as GERAN and vice versa. This document describes the service requirements for intra- and inter- system handover.
+
+The following subject areas are within the scope of these service requirements:
+
+- User perceived performance that may be influenced by handover;
+- Operational requirements relating to handover;
+- Security requirements.
+
+The requirements set forth in this document are service requirements, in that they fulfil the following:
+
+- The requirements are independent of the implementation of the UTRAN;
+- The extent to which the requirements are met are in principle verifiable using observables that are not internal to the UTRAN.

+### 10.2.43 TS 22.140 Multimedia messaging service; Stage 1
+
+This Technical Specification (TS) defines the stage one description of the non real-time Multimedia Messaging Service, MMS. Stage one is the set of requirements which shall be supported for the provision of non real-time multimedia messaging service, seen primarily from the subscriber's and service providers' points of view.
+
+This Technical Specification includes information applicable to network operators, service providers, terminal and network manufacturers.
+
+This Technical Specification contains the core requirements for the Multimedia Messaging Service, which is sufficient to provide a complete service.
+
+Additional functionalities not documented in this Technical Specification may implement requirements, which are considered outside the scope of this TS. Such additional functionality may be on a network-wide basis, nation-wide basis or particular to a group of users. Such additional functionality shall not compromise conformance to the core requirements of the service.
+
+This TS defines the requirements for MMS to be understood as a framework to enable non real-time transmissions for different types of media including such functionality as:
+
+- Multiple media elements per single message;
+- Negotiate different terminal and network MM capabilities;
+- Notification and acknowledgement of MM related events (e.g. delivery, deletion, ...);
+- Handling of undeliverable MM;
+- Flexible charging.
+
+The above list is not exhaustive.
+
+Thus the MMS enables a unified application, which integrates the composition, storage, access, and delivery of different kinds of media, e.g. text, voice, image or video in combination with additional mobile requirements.

+
+### **10.3.3 TS 23.007 Restoration procedures**
+
+The data stored in location registers are automatically updated in normal operation; the main information stored in a location register defines the location of each mobile station and the subscriber data required to handle traffic for each mobile subscriber. The loss or corruption of this data will seriously degrade the service offered to mobile subscribers; it is therefore necessary to define procedures to limit the effects of failure of a location register, and to restore the location register data automatically. The document defines the necessary procedures.
+
+The basic principle is that restoration should be based on radio contact to avoid faulty data being spread in the system.
+
+Subscriber data for supplementary services must also be correctly restored, although the impact on service of corruption of supplementary service data is less severe.
+
+Procedures for supporting these functions are defined in TS 29.002 and TS 29.060.
+
+The MAP operation "IMSI Attach" is used only in MAP version 1; in MAP version 2 the same function is performed by the MAP operation "Update Location Area". References in this specification to IMSI attach apply only to MAP version 1 network entities.
+
+If the restoration of subscriber data in the VLR is triggered by Location Updating or IMSI Attach, the VLR retrieves subscriber data from the HLR by sending an "Update Location" request, which triggers one or more "Insert Subscriber Data" operations from the HLR. The "Update Location" request may also be used to send the LMSI to the HLR.
+
+If the restoration of subscriber data in the VLR is triggered by a "Provide Roaming Number" request, the behaviour of the VLR depends on whether it is implemented according to MAP version 1 or MAP version 2. For MAP version 2, the VLR retrieves subscriber data from the HLR by sending a "Restore Data" request, which triggers one or more "Insert Subscriber Data" operations from the HLR. The "Restore Data" request is also used to send the LMSI to the HLR. For MAP version 1, the VLR retrieves subscriber data from the HLR by sending a "Send Parameters" request with parameter type "Subscriber Data", which cannot be used to send the LMSI to the HLR.
+
+The VLR number and MSC number in the subscriber data in the HLR are updated by the "Update Location" procedure.
+
+The Gateway GPRS Support Node (GGSN) is the point of PDN interconnection with the GSM PLMN supporting GPRS. The GGSN contains routing information for GPRS users with a PDP context active. The necessary procedures needed to restore GGSN data information after a restart is described in this document.
+
+The Serving GPRS Support Node (SGSN) is the node that is serving the MS. The SGSN stores information regarding e.g. mobility management, routing and security. The necessary procedures needed to restore this SGSN information after a restart is described in this document.
+
+A Type A Location Measurement Unit (LMU) is a network node, accessed over the GSM air interface that is functionally similar to an MS. All requirements associated with a non-GPRS MS in this specification apply also to a Type A LMU except where specified otherwise.

+### 10.3.5 TS 23.009 Handover procedures
+
+The document contains a detailed description of the handover procedures to be used in PLMNs. The purpose of the handover procedures, as described in the document, are to ensure that the connection to the Mobile Station (MS) or User Equipment (UE) is maintained as it moves from one cell or radio network to another. The document defines the circuit switched handover functionality based on the service requirements in TS 22.129.
+
+The present document considers the following four cases:
+
+- i) Handover between Base Stations connected to the same MSC, this is termed an Intra-MSC handover;
+- ii) Handover between Radio Network Subsystems connected to the same 3G\_MSC, this is termed an Intra-3G\_MSC handover/relocation. This case also includes inter-system handover between RNS and BSS if the 3G\_MSC supports the A-interface;
+- iii) Handover between Base Stations connected to different MSCs, this is termed an Inter-MSC handover. This category can be sub-divided into three further procedures:
+  - The Basic Inter-MSC Handover procedure, where the MS is handed over from a controlling MSC (MSC-A) to another MSC (MSC-B);
+  - The subsequent Inter-MSC Handover procedure, where the MS is handed over from MSC-B to a third MSC (MSC-B');
+  - The subsequent Inter-MSC hand back, where the MS is handed back from MSC-B to MSC-A.
+
+- iv) Handover between Radio Network Subsystems connected to different 3G\_MSCs, this is termed an Inter-3G\_MSC handover/relocation. This category can be divided into three further subprocedures:
+- The Inter-3G\_MSC Handover procedure from UMTS to GSM, where the UE/MS is handed over from a controlling 3G\_MSC (3G\_MSC-A) to an MSC (MSC-B);
+  - The Inter-3G\_MSC Handover procedure from GSM to UMTS, where the UE/MS is handed over from a controlling MSC (MSC-A) to a 3G\_MSC (3G\_MSC-B);
+  - The Inter-3G\_MSC Relocation procedure, where the UE is relocated from 3G\_MSC-A to 3G\_MSC-B. This procedure can also be combined with a hard change of radio resources (Hard Handover with switch in the core network).
+
+The MSC in this category can optionally be a 3G\_MSC supporting the A-interface. The three subprocedures do also cover subsequent handover/relocation to a third MSC-B' or 3G\_MSC-B' and subsequent handover/relocation back to MSC-A or 3G\_MSC-A.
+
+In both cases i) and iii) the same procedures as defined in the TS 08.08 and the TS 24.008 shall be used on the A-interface and on the Radio Interface, respectively.
+
+In case ii) the same procedures as defined in the TS 25.413 and the TS 24.008 shall be used on the Iu-interface. If the 3G\_MSC in case ii) also supports the A-interface, the TS 08.08 and the TS 24.008 shall be used on the A-interface.
+
+In case iii) the handover procedures shall transport the A-interface messages between MSC-A and MSC-B described in the Mobile Application Part (MAP), TS 29.002.
+
+In case iv) the handover procedures shall transport the A-interface messages between 3G\_MSC and MSC described in the Mobile Application Part (MAP), TS 29.002.
+
+In case iv) the relocation procedure shall transport the Iu-interface messages between 3G\_MSC-A and 3G\_MSC-B described in the Mobile Application Part (MAP), TS 29.002.
+
+The interworking between the TS 29.002 protocol and the TS 08.08 protocol is described in TS 29.010.
+
+Handovers, which take place on the same MSC are termed Intra-MSC handovers; this includes both Inter-BSS and Intra-BSS handovers.
+
+Handovers, which take place on the same 3G\_MSC are termed Intra-3G\_MSC handovers; this includes Inter-RNS handovers and optionally RNS to BSS and BSS to RNS handovers.
+
+The document also covers the requirements for handover in ongoing GSM voice group calls, directed retry and handover without a circuit connection between (U)MSCs. The document does not consider the case of handovers between radio channels on the same BSS (Intra-BSS handover) or the handover of packet radio services. The Inter-RNS handover case that results in a relocation is covered by the present document but not other Inter-RNS or Intra-RNS handover cases.
+
+For voice broadcast calls in GSM, the speaker uses normal point-to-point handover procedures, whilst the listeners use idle mode cell reselection procedures, as for the voice group call listeners.
+
+Voice group calls are only applicable to GSM and handover of voice group calls is therefore only possible in GSM.
+
+Inter-MSC hand-over imposes a few limitations on the system. After inter-MSC handover:
+
+- Call re-establishment is not supported.
+
+The list of TS 08.08 features supported during and after Inter-MSC handover is given in TS 09.08.
+
+In the Inter-MSC handover case, the interworking between a Phase 1 BSSMAP protocol possibly used by one MSC and the Phase 2 BSSMAP protocol used in the Phase 2 MAP protocol on the E-interface is performed by this MSC.
+
+NOTE – The message primitive names used in the SDL diagrams and message flows in the present document do not represent the actual messages specified in the GSM or 3GPP stage 3 technical specifications. The primitive names are only intended to be indicative of their use in the document.

+### 10.3.6 TS 23.011 Technical realization of supplementary services – General aspects
+
+The document describes the general aspects on how supplementary services in the GSM system are realized from a technical point of view.
+
+Description of technical realization for specific supplementary services can be found in TS 23.08x and 23.09x-series technical specifications.
+
+All supplementary services may require signalling on the radio path. Signalling procedures and messages used are defined in the TS 24.08x and 24.09x-series of technical specifications.
+
+For some supplementary services, information needs to be transferred between the Home Location Register (HLR), the Visitor Location Register (VLR) and the Mobile services Switching Centre (MSC). Signalling procedures for such information transfer are defined in TS 29.002.
+
+Definitions and descriptions of supplementary services are given in the TS 22.08x and TS 22.09x-series of technical specifications.
+
+Definitions are given in TS 22.004.
+
+NOTE – The technical specifications on the technical realization of supplementary services do not distinguish between subscriber, user and customer, since all three do not fully cover the textual needs. Generally the term "subscriber" is used, even if this person is not having the subscription.

+### 10.3.7 TS 23.012 Location management procedures
+
+The document describes the location management procedures for the circuit switched domain, with respect to the application level functional behaviour. This is to be distinguished from the corresponding protocol handling behaviour, which is specified in TS 29.002. The following location management procedures are included:
+
+- Location updating;
+- Location cancellation;
+- MS purging;
+- IMSI attach/detach.
+
+The procedures in the Mobile Station (MS) are described in GSM 03.22. The procedures between MSC, VLR and HLR utilize the Mobile Application Part (MAP) and details concerning the protocol handling are contained in TS 29.002.
+
+The document excludes location management procedures for the packet switched domain, which are covered in TS 23.060.
+
+The descriptions herein depict a logical separation between the MSC and VLR. This logical separation, as well as the messages transferred between the two logical entities are the basis of a model used to define the externally visible behaviour of the MSC/VLR, which may be a single physical entity. They do not impose any requirement except the definition of the externally visible behaviour.

+### 10.3.9 TS 23.015 Technical realization of Operator Determined Barring (ODB)
+
+The network feature Operator Determined Barring (ODB) allows a network operator or service provider to regulate access by subscribers to GSM services, by the barring of certain categories of incoming or outgoing traffic or of roaming. Operator Determined Barring applies to all bearer services and teleservices except the Emergency Call teleservice; the teleservice Short Message Point-to-Point is therefore subject to Operator Determined Barring in the same way as circuit-switched calls.
+
+The application of specific categories of Operator Determined Barring to a subscription is controlled by the network operator or service provider, using administrative interaction at the HLR; this interface is not standardized.

+### 10.3.11 TS 23.018 Basic call handling – Technical realization
+
+This Technical Specification (TS) specifies the technical realization of the handling of calls originated by a UMTS or GSM mobile subscriber and calls directed to a UMTS or GSM mobile subscriber, up to the point where the call is established. Normal release of the call after establishment is also specified.
+
+In this specification, the term MS is used to denote a UMTS or GSM MS, as appropriate.
+
+The handling of DTMF signalling and Off-Air Call Set-Up (OACSU) are not described in this specification.
+
+The details of the effects of UMTS or GSM supplementary services on the handling of a call are described in the relevant 23.07x, 23.08x and 23.09x series of specifications.
+
+The specification of the handling of a request from the HLR for subscriber information is not part of basic call handling, but is required for both CAMEL (TS 23.078) and optimal routing (TS 23.079). The use of the Provide Subscriber Information message flow is shown in TS 23.078 and TS 23.079.
+
+The specification of the handling of data calls rerouted to a SIWFS is described in TS 23.054.
+
+The logical separation of the MSC and VLR, and the messages transferred between them is the basis of a model used to define the externally visible behaviour of the MSC/VLR, which is a single physical entity. They do not impose any requirement except the definition of the externally visible behaviour.
+
+If there is any conflict between this specification and the corresponding stage 3 specifications (TS 24.008, TS 25.413, GSM 08.08 and TS 29.002), the stage 3 specifications shall prevail.

+### 10.3.12 TS 23.032 Universal Geographical Area Description (GAD)
+
+The document defines an intermediate universal Geographical Area Description, which subscriber applications or GSM services can use and the network can convert into an equivalent radio coverage map.
+
+For GSM services which involve the use of an "area", it can be assumed that in the majority of cases the Service Requester will be forbidden access to data on the radio coverage map of a particular PLMN and that the Service Requester will not have direct access to network entities (e.g. BSC/BTS).
+
+The interpretation by the PLMN operator of the geographical area in terms of cells actually used, cells that are partly within the given area and all other technical and quality of service aspects are out of the scope of the document.
+
+This specification also provides a description of velocity that may be associated with a universal Geographical Area Description when both are applied to a common entity at a common time.

+### 10.3.13 TS 23.034 High Speed Circuit Switched Data (HSCSD); Stage 2
+
+The document contains the stage 2 service description for a High Speed Circuit Switched Data (HSCSD) on GSM/GERAN. HSCSD utilizes the multislot mechanism, i.e. using multiple traffic channels (/bearers) for the communication. In Iu mode one bearer can provide all needed data rates, and the multislot mechanism is therefore not needed. The Iu mode aspects concerning HSCSD are described exclusively.
+
+In analogy with ITU-T Recs. I.130 [12] (refer to annex A) and ITU-T Rec. Q.65 [18] (Stage 2 of the method for characterization of services supported by an ISDN), the second stage of the HSCSD is defined as follows.
+
+Stage 2 identifies the functional capabilities and information flows needed to support the service as described in High Speed Circuit Switched Data (HSCSD); Stage 1, TS 22.034. Furthermore, it identifies various possible physical locations for the functional capabilities. The output of stage 2, which is signalling system independent, is used as an input to stage 3, the design of signalling system and switching specifications.

+### 10.3.15 TS 23.040 Technical realization of Short Message Service (SMS)
+
+The document describes the Short Message Service (SMS) for GSM/UMTS networks. It defines:
+
+- The services and service elements;
+- The network architecture;
+- The Service Centre functionality;
+- The MSC functionality (with regard to the SMS);
+- The SGSN functionality (with regard to the SMS);
+- The routing requirements;
+- The protocols and protocol layering;
+
+For the Teleservice Short Message Service as specified in the GSM TS 02.03 and TS 22.105.
+
+The use of radio resources for the transfer of short messages between the MS and the MSC or the SGSN is described in TS 24.011 "Short Message Service Support on Mobile Radio Interface", and is dealt with in that specification.
+
+The network aspects of Short Message Service provision are outside the scope of the present document (i.e. the provision of network connectivity between the PLMN subsystems). There is no technical restriction within the document for the transfer of short messages between different PLMN's. Any such restriction is likely to be subject to commercial arrangements and PLMN operators must make their own provision for interworking or for preventing interworking with other PLMN's as they see fit.
+
+The required and assumed network service offered to the higher layers is defined in the present document.

+### 10.3.18 TS 23.054 Shared interworking functions; Stage 2
+
+The document defines the stage two description of the Shared Interworking Function (SIWF) on Global System for Mobile communications (GSM).
+
+A stage one description does not exist because this service is not visible to the service subscribers and users. This stage two identifies the functional Capabilities and information flows needed to support the service. The signalling system protocols and switching functions needed to implement this service are defined in the relevant specifications.
+
+Interworking with other networks (e.g. PSTN) needs the presence of specific functions associated with the MSC, known as interworking functions (IWF). The IWFs depend on the type of network with which it is desired to interconnect and the type of service desired.
+
+A Shared Interworking Function is a network function that may be used by any MSC in the same PLMN to provide interworking for a data/fax call. Whereas an IWF can only be used by its MSC, the SIWF can be used by several other network nodes e.g. any MSC within the same PLMN (the concept is not limited to a certain number of MSCs). SIWF is applied to data services in GSM Phase 2 and GSM Phase 2+ (as defined in GSM 02.02, GSM 02.03 and GSM 02.34).
+
+The usage of a SIWF requires no additional manipulation at the MS.
+
+There is an interest to have a Shared Interworking Function (SIWF) for the following reasons:
+
+- Possibility to fabricate/obtain the specific functionality needed for data services in areas where data traffic is expected to be low;
+- Handling of data calls in case of local overload of the data traffic;
+- Quick introduction and roll-out of new data services.

+### 10.3.24 TS 23.078 CAMEL; Stage 2
+
+The document specifies the stage 2 description for the third phase (see TS 22.078) of the Customized Applications for Mobile network Enhanced Logic (CAMEL) feature which provides the mechanisms to support services of operators which are not covered by standardized GSM services even when roaming outside the HPLMN.
+
+The CAMEL feature is a network feature and not a supplementary service. It is a tool to help the network operator to provide the subscribers with the operator specific services even when roaming outside the HPLMN.
+
+In this specification, the GSM Service Control Function (gsmSCF) is treated as being part of the HPLMN. The regulatory environment in some countries may require the possibility that the gsmSCF and the HPLMN are controlled by different operators, and the gsmSCF and the HPLMN are therefore distinct entities.
+
+In the third phase the CAMEL feature supports:
+
+- Mobile originated and forwarded calls;
+- Mobile terminating calls;
+- Any time interrogation;
+- Active location information retrieval;
+- Suppression of announcements;
+- Announcements, in band user interaction;
+- Charging features;
+
+- Supplementary service invocation notifications;
+- USSD interaction with the gsmSCF;
+- North American carrier selection;
+- Mobility Management event notifications;
+- Change of Calling Line Identification Presentation Indicator for an MO call to restricted;
+- Subscribed dialled services;
+- Serving network dialled services;
+- MO SMS;
+- GPRS data transmission;
+- Mobility management;
+- Notification to CSE of change of subscriber data;
+- Any Time Modification;
+- Any Time Interrogation of subscription Information;
+- T-BCSM in the VMSC and terminating AoC;
+- Interworking with Location Services;
+- Multiple Subscriber Profile;
+- Active Location Retrieval;
+- Call Gapping.
+
+Note that CAMEL is not applicable to Emergency Setup (Tele Service 12), i.e., in case an Emergency call has been requested the gsmSSF shall not be invoked.
+
+The mechanism described in this standard especially addresses the need for information exchange between the VPLMN or IPLMN and the HPLMN for support of operator specific services. Any user procedures for the control of operator-specific services are outside the scope of this standard. Subscribers who have subscribed to operator-specific services, and therefore need the functional support of the CAMEL feature, shall be marked in the HPLMN and VPLMN. In case a subscriber is marked to need CAMEL support, the appropriate procedures that provide the necessary information to the VPLMN or the HPLMN are invoked. It is possible for the HPLMN to instruct the VPLMN or IPLMN to interact with a gsmSCF, which is controlled by the HPLMN.
+
+The specification of operator specific services is outside the scope of this standard.

+### 10.3.25 TS 23.079 Support of Optimal Routing (SOR) – Phase 1; Stage 2
+
+The document specifies the technical realization of the first phase of the network feature Support of Optimal Routing (SOR). The first phase of SOR provides:
+
+- As a network operator option, a method to route a call from one mobile subscriber directly to another mobile subscriber who is in the same country as the calling mobile subscriber or in the called mobile subscriber's home country, without needing to connect the call via the HPLMN of the called subscriber, even though the called mobile subscriber has roamed outside his HPLMN;
+- A method to forward calls when a called mobile subscriber who has roamed outside his home country is busy, or is not reachable, or does not reply, to a forwarded-to destination in the HPLMN country of the called subscriber or the VPLMN country of the called subscriber, without needing to connect the forwarded call via the VPLMN of the called subscriber;
+- A method to combine the optimal routing described in the first bullet point above with the optimal routing described in the second bullet point above.
+
+Optimal Routing of a call is permitted only if all entities involved in handling the call support Optimal Routing.
+
+Other cases of optimal routing (e.g. calls where the calling and called subscribers are in different countries, forwarding to a mobile subscriber or multiple forwarding) will be considered for inclusion in later phases.

+
+The document gives the stage 2 description of the call barring services.
+
+The possibility for a mobile subscriber to have certain categories of calls barred originated from or terminated at his access:
+
+Barring of outgoing calls:
+
+- Barring of all outgoing calls (BAOC) (Barring program 1);
+- Barring of outgoing international calls (BOIC) (Barring program 2);
+- Barring of outgoing international calls EXCEPT those directed to the home PLMN country (BOIC-exHC) (Barring program 3).
+
+Barring of incoming calls:
+
+- Barring of all incoming calls (BAIC) (Barring program 1);
+- Barring of incoming calls when roaming outside the home PLMN country (BIC-Roam) (Barring program 2).
+
+NOTE – The call barring program "incoming calls when roaming outside the home PLMN country" (clause 2) is only relevant if as a general rule the called mobile subscriber pays the charges for the forwarded part of the call from his home PLMN country to any other country.

+### 10.3.34 TS 23.090 Unstructured Supplementary Service Data (USSD); Stage 2
+
+The document gives the stage 2 description of Unstructured Supplementary Service Data (USSD).
+
+The unstructured supplementary service data (USSD) mechanism allows the Mobile Station (MS) user and a PLMN operator defined application to communicate in a way which is transparent to the MS and to intermediate network entities. The mechanism allows development of PLMN specific supplementary services. The following diagram shows how handling of USSD is carried out, independently of the applications.
+
+![Diagram illustrating the handling of USSD across network entities: USER, MS, MSC, VLR, and HLR. Each entity contains an 'Applications' block and a 'USSD Handler' block. The USER connects to the MS. The MS connects to the MSC. The MSC connects to the VLR. The VLR connects to the HLR. Within each entity, the Applications block connects to the USSD Handler block. The USSD Handler blocks are interconnected across the entities.](2fbb410da68e626ba5e994d872031f14_img.jpg)

+
+**Figure 10-3/Q.1741.1 – Handling of USSD**
+
+The document defines the requirements for handling USSD at the MS and network entities. It does not include specification of particular applications, nor does it specify how a particular application is selected. Where more than one application exists at a network entity, routing of messages to the correct application is carried out by the USSD handler. The MMI for USSD is specified in TS 22.030 and TS 22.090. The alphabet indicator and the data-coding scheme are defined in TS 23.038.
+
+USSD may be initiated by the MS user, or by the network in the following ways:
+
+- Network initiated USSD;
+- Mobile initiated USSD.

+### 10.3.48 TS 23.127 Virtual Home Environment; Stage 2
+
+The document specifies the stage 2 of the Virtual Home Environment and Open Service Architecture.
+
+Virtual Home Environment (VHE) is defined as a concept for personal service environment (PSE) portability across network boundaries and between terminals. The concept of the VHE is such that users are consistently presented with the same personalized features, User Interface customization and services in whatever network and whatever terminal (within the capabilities of the terminal and
+
+the network), wherever the user may be located. For Release 1999, e.g. CAMEL, MExE and SAT are considered the mechanisms supporting the VHE concept.
+
+The Open Service Architecture (OSA) defines an architecture that enables operator and third party applications to make use of network functionality through an open standardized API (the OSA API). OSA provides the glue between applications and service capabilities provided by the network. In this way applications become independent from the underlying network technology. The applications constitute the top level of the Open Service Architecture (OSA). This level is connected to the Service Capability Servers (SCSs) via the OSA API. The SCSs map the OSA API onto the underlying telecom specific protocols (e.g. MAP, CAP etc.) and are therefore hiding the network complexity from the applications.
+
+Applications can be network/server centric applications or terminal centric applications. Terminal centric applications reside in the Mobile Station (MS). Examples are MExE and SAT applications. Network/server centric applications are outside the core network and make use of service capability features offered through the OSA API. (Note that applications may belong to the network operator domain although running outside the core network. Outside the core network means that the applications are executed in Application Servers that are physically separated from the core network entities).

+### 10.3.50 TS 23.140 Multimedia Messaging Service (MMS)
+
+The document defines the stage 2 and stage 3 description of the non-real-time Multimedia Messaging Service, MMS. Stage 2 identifies the functional capabilities and information flows needed to support the service described in stage 1.
+
+The document includes information applicable to network operators, service providers and terminal, switch and database manufacturers.
+
+The document contains the core functions for a non-real-time Multimedia Messaging Service, MMS, which are sufficient to provide a basic service.
+
+MMS uses a number of technologies to realise the requirements of the stage 1 description (TS 22.140). The document describes how the service requirements are realized with the selected technologies. As far as possible existing protocols (e.g. WAP, SMTP, ESMTP as transfer protocols; lower layers to provide push, pull, notification) and existing message formats (e.g. SMIL, MIME) shall be used for the realization of the Multimedia Messaging Service.
+
+This specification serves as a foundation for the development of MMS for release '99.

+### 10.4.2 TS 24.007 Mobile Radio Interface Signalling Layer 3 – General aspects
+
+The document defines the principal architecture of layer 3 and its sublayers on the GSM Um interface, i.e. the interface between Mobile Station (MS) and network; for the CM sublayer, the description is restricted to paradigmatic examples, call control, supplementary services, and short message services for non-GPRS services. It also defines the basic message format and error handling applied by the layer 3 protocols.
+
+For non-GPRS services the communication between sublayers and adjacent layers and the services provided by the sublayers are distributed by use of abstract service primitives. But only externally observable behaviour resulting from the description is normatively prescribed by the document.
+
+For GPRS services in addition the local information transfer and stimuli sent between sublayers is informatively included within Annex C of the document.

+### 10.4.7 TS 24.022 Radio Link Protocol (RLP) for Data and Telematic Services on the (MS-BSS) Interface and the Base Station System – Mobile-services Switching Centre (BSS-MSC) Interface
+
+The document specifies the Radio Link Protocol (RLP) for circuit switched data transmission within the GSM and UMTS PLMN. RLP covers the Layer 2 functionality of the ISO OSI Reference Model (ISO 7498) [43]. It is based on ideas contained in ISO/IEC 3309 [6], ISO/IEC 4335 [7] and ISO/IEC 7809 [8] (HDLC of ISO) as well as ITU-T Recs. X.25 [38] and Q.92x [19-22] (LAP-B and LAP-D of ITU, respectively.) RLP has been tailored to the special needs of digital radio transmission. RLP provides to its users the OSI Data Link Service ITU-T Rec. X.212 | ISO/IEC 8886 [9].
+
+RLP is intended for use with non-transparent data-transfer. Protocol conversion may be provided for a variety of protocol configurations. Those foreseen immediately are:
+
+- Character-mode protocols using start-stop transmission (IA5);
+- X.25 [38] LAP-B.
+
+For reasons of better presentation, material about protocol conversion has been placed within those Specifications concerned with the relevant Terminal Adapters, i.e. TS 27.002 for the asynchronous case and TS 27.003 for the synchronous case. Care must be taken that that material also applies to Interworking Functions; see TS 29.006 and TS 29.007.

+### 10.5.4 TS 26.090 AMR speech Codec; Transcoding functions
+
+This Technical Specification (TS) describes the detailed mapping from input blocks of 160 speech samples in 13-bit uniform PCM format to encoded blocks of 95, 103, 118, 134, 148, 159, 204, and 244 bits and from encoded blocks of 95, 103, 118, 134, 148, 159, 204, and 244 bits to output blocks of 160 reconstructed speech samples. The sampling rate is 8000 samples/s leading to a bit rate for the encoded bit stream of 4.75, 5.15, 5.90, 6.70, 7.40, 7.95, 10.2 or 12.2 kbit/s. The coding scheme for the multi-rate coding modes is the so-called Algebraic Code Excited Linear Prediction Coder, hereafter referred to as ACELP. The multi-rate ACELP coder is referred to as MR-ACELP.
+
+In the case of discrepancy between the requirements described in this TS and the fixed points computational description (ANSI-C code) of these requirements contained in TS 26.073, the description in TS 26.073 will prevail. The ANSI-C code is not described in this TS, see TS 26.073 for a description of the ANSI-C code.
+
+The transcoding procedure specified in this TS is mandatory for systems using the AMR speech codec.

+
+This document describes the Source Controlled Rate (SCR) operation of the Adaptive Multi-Rate speech Codec in Codec Types UMTS\_AMR and GSM\_AMR for the UMTS system. The implementation of this SCR operation is mandatory in all UMTS equipment.
+
+The structure of distributing the various functions between system entities is not mandatory for implementation, as long as the operation on the speech decoder output remains the same.
+
+Annex A describes the Discontinuous Transmission (DTX) operation of the Adaptive Multi-Rate speech Codec in Codec Type GSM\_AMR for the GSM system. This annex is the former GSM 06.93 (release 98).
+
+Annexes B to E describe the SCR operation of the Adaptive Multi-Rate speech Codec in Codec Types GSM\_EFR, TDMA\_EFR, TDMA\_US1 and PDC\_EFR for the UMTS system.

+
+This document specifies two alternatives for the Voice Activity Detector (VAD) to be used in the Discontinuous Transmission (DTX) as described in TS 26.093. Implementors of mobile station and infrastructure equipment conforming to the AMR specifications can choose which of the two VAD options to implement. There are no interoperability factors associated with this choice.
+
+The requirements are mandatory on any VAD to be used either in User Equipment (UE) or Base Station Systems (BSS)s that utilize the AMR speech codec.

+### 10.5.12 TS 26.104 AMR speech codec; Floating point C-code
+
+This Technical Specification (TS) contains an electronic copy of the ANSI-C code for a floating-point implementation of the Adaptive Multi-Rate codec. This floating-point codec specification is mainly targeted to be used in multimedia applications such as the 3G-324M terminal specified in TS 26.110, or in packet-based (e.g., H.323 [44]) applications. The bit-exact fixed-point ANSI-C code in TS 26.073 remains the preferred implementation for all applications, but the floating-point codec may be used instead of the fixed-point codec when the implementation platform is better suited for a floating-point implementation. It has been verified that the fixed-point and floating-point codecs interoperate with each other without any artifacts.
+
+The floating-point ANSI-C code in this specification is the only standard conforming non-bit-exact implementation of the Adaptive Multi Rate speech transcoder (TS 26.090), Voice Activity Detection (TS 26.094), comfort noise generation (TS 26.092), and source controlled rate operation (TS 26.093). The floating-point code also contains example solutions for substituting and muting of lost frames (TS 26.091).
+
+The fixed-point specification in TS 26.073 shall remain the only allowed implementation for the 3G mandatory speech services and the use of the floating-point codec is strictly limited to other services.
+
+The floating-point encoder in this specification is a non-bit-exact implementation of the fixed-point encoder producing quality indistinguishable from that of the fixed-point encoder. The decoder in this specification is functionally a bit-exact implementation of the fixed-point decoder, but the code has been optimized for speed and the standard fixed-point libraries are not used as such.

+### 10.6.1 TS 27.001 General on Terminal Adaptation Function(s) (TAF) for Mobile Station(s) (MS)
+
+The document is based on the principles of terminal adaptor functions presented in the ITU-T I-series of Recommendations (I.460 to V.110/I.463) [14]-[17].
+
+The PLMN supports a wide range of voice and non-voice services in the same network. In order to enable non-voice traffic in the PLMN, there is a need to connect various kinds of terminal equipment to the Mobile Termination (MT). The target of the present document is to outline the functions needed for the terminal adaptation.
+
+In the TS 22.002 the bearer services are described. The general network configuration is described in TS 23.002 and the GSM PLMN access reference configuration is defined in GSM 04.02. The various connection types used in the GSM PLMN are presented in GSM 03.10. Terminology used in the present document is presented in GSM 01.04 (ETR 350), 3GPP TR 21.905 and TS 29.990. For support of data services between a PLMN and other networks see TS 29.007.
+
+The document is valid for a 2nd generation PLMN (GSM) as well as for a 3rd generation PLMN (UMTS). If text applies only for one of these systems it is explicitly mentioned by using the terms "GSM" and "UMTS". If text applies to both of the systems, but a distinction between the ISDN/PSTN and the PLMN is necessary, the term "PLMN" is used.
+
+Descriptions related to facsimile are not applied to UMTS.

+### 10.6.4 TS 27.005 Use of Data Terminal Equipment – Data Circuit terminating Equipment (DTE – DCE) interface for Short Message Service (SMS) and Cell Broadcast Service (CBS)
+
+This Technical Specification (TS) defines three interface protocols for control of SMS functions within a GSM/UMTS mobile telephone from a remote terminal via an asynchronous interface.
+
+This document defines a binary protocol ("Block Mode"). The protocol includes error protection and is suitable for use where the link may not be completely reliable. It will be of particular use where control of remote devices is required. Efficient transfer of binary encoded user data is possible.
+
+This document defines a character-based interface based on "AT" commands ("Text Mode"). This mode is suitable for unintelligent terminals or terminal emulators, and for application software built on command structures like those defined in ITU-T Rec. V.25 *ter* [32]. Some of the commands defined in clause 3 will also be useful for implementations of clause 2 and/or clause 4, for example enabling an indication of incoming SMS messages.
+
+This document defines a character-based interface with hex-encoded binary transfer of message blocks ("PDU Mode"). This mode is suitable for software drivers based on AT command structures which do not understand the content of the message blocks and can only pass them between the MT and "upper level" software resident in the TE.
+
+In all three modes, the terminal is considered to be in control for SMS/CBS transactions.
+
+This specification considers the mobile termination to be a single entity. Other 3GPP/GSM Technical Specifications describe the split of functionality between the mobile equipment and (U)SIM.
+
+The three "modes" referred to above, are represented in Figure 10-4.
+
+The "Block mode" is a self contained mode in its own right, and when entered, control will remain within that mode until the procedures to exit the mode are executed, after which control is returned to the V.25 *ter* [32] "command" state or "on-line command" state.
+
+The "Text" and "PDU" modes are not in themselves V.25 *ter* [32] states, but are simply sets of commands, which will operate in either the V.25 *ter* [32] "command" state or "on-line command" state. The "Text" and "PDU" modes are transitory states and after each operation, control is automatically returned to the V.25 *ter* [32] "command" state or "on-line command" state. Whilst in the V.25 *ter* [32] command state, the MS is available to handle incoming and outgoing calls such as Data or Facsimile.

Inside this large circle are two smaller circles side-by-side: the left one is labeled "SMS text mode" and the right one is labeled "SMS PDU mode". Below the large circle, a vertical line connects it to a rectangular box labeled "SMS block mode". To the right of this box, the text "Q.1741.1 F10.6.4-1" is displayed.

+**Figure 10-4/Q.1741.1 – Block, text and PDU modes**
+
+In the "Block mode" and "PDU" mode a mobile is not permitted to modify any component of an SMS/CBS message received from the air interface or an SMS message received from a TE, before passing it on, except where TS 23.040 or TS 23.041 defines a "component modification facility" and where this "component modification facility" is supported by the mobile. In the Text Mode the mobile may be unable to display characters coded in particular coding schemes. In this case, the mobile shall behave as described in TS 23.038 and assume the coding scheme to be the GSM 7 bit default alphabet.

+### 10.6.5 TS 27.007 AT command set for 3G User Equipment (UE)
+
+The document specifies a profile of AT commands and recommends that this profile be used for controlling Mobile Equipment (ME) functions and GSM/UMTS network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). The command prefix +C is reserved for Digital Cellular in ITU-T Rec. V.25 *ter* [32]. The present document has also the syntax details used to construct these extended GSM/UMTS commands. Commands from ITU-T Rec. V.25 *ter* [32] and existing digital cellular standards (TIA IS-99 [40] and TIA IS-135 [41]) are used whenever applicable. Some of the new commands are defined such way that they can be easily applied to ME of networks other than GSM/UMTS. ITU-T Recs. T.31 [24] and T.32 [25] fax AT commands may be used for GSM/UMTS fax transmission from TE. GSM/UMTS Short Message Service AT commands are defined in TS 27.005. GPRS AT commands are defined in clause 10 of this specification. The present document assumes an abstract architecture comprising a TE (e.g. a computer) and a ME interfaced by a TA (see Figure 10-5). The span of control of the defined commands should allow handling of any physical implementation that this abstract architecture may lead to:
+
+- TA, ME and TE as three separate entities;
+- TA integrated under the ME cover, and the TE implemented as a separate entity;
+- TA integrated under the TE cover, and the ME implemented as a separate entity;
+- TA and ME integrated under the TE cover as a single entity.
+
+The commands described in the present document may be observed on the link between the TE and the TA. However, most of the commands retrieve information about the ME, not about the TA.
+
+![Diagram illustrating the setup for Figure 10-5/Q.1741.1. It shows three main components: TE (Terminal Equipment), TA (Terminal Adaptor), and ME (Mobile Equipment). The TE is connected to 'User and applications' via a vertical double-headed arrow. The TE sends 'AT cmds' to the TA and receives 'Responses' from it. The TA sends 'ME status' to the ME and receives 'ME control' from it. The ME is connected to the 'Network' via a vertical double-headed arrow labeled 'Network messages'. A small text 'Q.1741.1 F10.6.5-1' is in the bottom right corner.](4f3c8d71b3b182deb469aed61870e3fe_img.jpg)

+
+Interface between TE and TA is intended to operate over existing serial (ITU-T Rec. V.24 [30]) cables, infrared link, and all link types with similar behaviour. For correct operation, many of the defined commands require eight-bit data and, therefore, it is recommended that TE-TA link be set to eight-bits/ byte mode. (For infrared operation implementation refer informative references IrDA.
+
+For embedding AT commands and data during online data state refer to TTA IS-617 [42] and ITU-T Rec. V.80 [35].) Interface between TA and ME is dependent on the interface in the ME.

+### 10.7.2 TS 29.007 General requirements on interworking between the PLMN and the ISDN or PSTN
+
+The document identifies the Mobile-services Switching Centre/Interworking Functions (MSC/IWFs) and requirements to support interworking between:
+
+- PLMN and PSTN;
+- PLMN and ISDN.
+
+For circuit switched services in the PLMN, it is not possible to treat ISDN and PSTN as one type of network, even when both ISDN and PSTN subscribers are served by the same exchange because of the limitations of the PSTN subscriber's access i.e. analogue connection without D-channel signalling.
+
+Within the document, the requirements for voice and non-voice (data) calls are considered separately.
+
+Descriptions related to facsimile are not applied to UMTS.

+#### 10.7.4 TS 29.011 Signalling interworking for supplementary services
+
+This Technical Specification is to provide a detailed specification for interworking between the A interface protocol and the Mobile Application Part for handling of supplementary services. The MAP interfaces of interest are the B-, C-, D- and E-interfaces.
+
+The A-, C-, D- and E-interfaces are physical interfaces while the B-interface is an internal interface defined for modelling purposes. Information relating to the modelling interface is not normative in this specification.
+
+Supplementary service signalling may be passed by the MSC/VLR between the A- and E-interfaces after inter-MSC handover. This procedure is transparent as far as supplementary services are concerned therefore interworking concerning this process is not described in this specification.

+### 10.7.14 TS 29.198 Open Services Architecture API – Part 1
+
+This document specifies the stage 3 of the Open Service Architecture (OSA) Application Programming Interface (API). The concepts and the functional architecture of the Open Service Architecture (API) are described by TS 23.127. This document describes the stage 3 specification of the Open Service Architecture API.
+
+The Open Service Architecture defines an architecture that enables service providers to make use of network functionality through an open standardized interface, i.e. the OSA API. The network functionality is described as Service Capability Servers. Within the OSA concepts the following Service Capability Servers are identified:
+
+- CAMEL Service Environment (see in TS 23.078)
+- WAP execution platform (i.e. WAP Gateway & WAP Push Proxy)
+- Home Location Register (HLR)
+
+The stage 3 documentation of the OSA R'99 API consists of two parts:
+
+– **The API specification (Part 1)**
+
+This is a normative stage 3 specification of the capabilities of the OSA R'99 API and describes the OSA API interface classes, containing class diagrams (see section 6), state transition diagrams (see section 7), data type definitions (section 8), and the IDLs (see section 9).
+
+– **The Mapping specification of the OSA R'99 API and the network protocols (Part 2)**
+
+This is an informative specification to provide an example how the OSA API can be mapped on the network protocols (i.e. MAP, CAP and WAP). It is an informative document, since this mapping is considered as implementation/vendor dependent. On the other hand this mapping will provide potential service designers with a better understanding of the relationship of the OSA API interface classes and the behaviour of the network associated to these interface classes.
+
+The OSA API Stage 3 activity is performed jointly with ETSI SPAN3's Service Provider Access Requirements activity. The contents of this document is related to the jointly owned 3GPP & ETSI document referred as the API Master document, which contains the API interface descriptions that are common and differentiated between ETSI & 3GPP.

+#### 10.9.5 TS 32.104 3G Performance Management
+
+The document describes the requirements for the management of performance measurements and the collection of performance measurement data across a 3G network. It defines the administration of measurement schedules by the Network Element Manager (EM), the generation of measurement results in the Network Elements (NEs) and the transfer of these results to one or more Operations Systems, i.e. EM(s) and/or Network Manager(s) (NM(s)).
+
+The basic Performance Management concept that the document is built upon is described. The requirements how an EM administers the performance measurements and how the results can be collected are defined in detail. The file format for the bulk transfer of performance measurement results to the NM is specified, the file transfer procedure utilized on that interface is described. A set of measurements available for collection by NEs is described; effort has been made to ensure consistency in the definition of measurements between different NEs.
+
+The following is beyond the scope of the document, and therefore the document does not describe:
+
+- The formal definition of the interface that the EM uses to administer performance measurements in the NEs;
+- The formal definition of the interface that the EM uses to collect measurement results from the NEs;
+
+- How the data, once accumulated and collected, could or should be processed, stored, or presented to an end user;
+- The information which may be obtained through the collection and processing of call or event related records which have been produced by the NEs primarily for the purpose of raising bills and other charges.
+
+The management requirements have been derived from existing telecommunications operations experience. The management definitions were then derived from other standardization work so as to minimize the re-invention factor. References are given as appropriate.
+
+The objectives of this standardization are:
+
+- To provide the descriptions for a standard set of measurements;
+- To produce a common description of the management technique for measurement administration and result accumulation; and
+- To define a method for the bulk transmission of measurement results across a management interface.
+
+The definition of the standard measurements is intended to result in comparability of measurement data produced in multi-vendor 3G networks, for those measurement types that can be standardized across all vendors' implementations.
+
+As far as possible, existing standardization in the area of Performance Management has been reused and enhanced where particular requirements, peculiar to the mobile telephony environment, have been recognized.
+
+The document considers all the above aspects of Performance Management for a 3G network and its NEs defined in the 3G core Technical Specifications. However, only those aspects which are specific to a 3G system and particular to 3G-network operation are included in the document.

+### 10.9.6 TS 32.106-1 Telecommunication Management; Configuration Management; Part 1: 3G configuration management; Concept and requirements
+
+The document describes the Configuration Management (CM) aspects of managing a 3G network. This is described from the management perspective in TS 32.101 and TS 32.102.
+
+The document defines a set of controls to be employed to effect set-up and changes to a 3G network in such a way that operational capability and Quality Of Service (QOS), network integrity and system inter working are ensured. In this way, the present document describes the interface definition and behaviour for the management of relevant 3G NEs in the context of the described management environment. The context is described for both the management system (OS) and Network Element (NE) functionality.
+
+This document contains the specific definitions for the standardized N interface, which are necessary to follow for compliance to this specification.
+
+The Itf-N for CM is built up by a number of Integration Reference Points (IRPs) and a related Name Convention, which realize the functional capabilities over this interface. The basic structure of the IRPs is defined in TS 32.101 and TS 32.102. For CM, a number of IRPs (and the Name Convention) are defined herein, used by this as well as by other specifications for Telecom Management produced by 3GPP. All these are included in Parts 2 through 8 of the document as follows:
+
+- Notification IRP Information Service version 1: 32.106 Part 2

+### 10.9.7 TS 32.106-2 Telecommunication Management; Configuration Management; Part 2: Notification Integration Reference Point; Information Service version 1
+
+Network Elements (NEs) under management generate events to inform event receivers about occurrences within the network that may be of interest to event receivers. There are a number of categories of events. Alarm, as specified in Alarm IRP: Information Service TS 32.111-2, is one member of this category.
+
+The purpose of Notification IRP is to define an interface through which an IRPManager (typically a network management system) can subscribe to IRPAgent (typically an Element Manager (EM) or a NE) for receiving network events. It also specifies attributes carried in the network events. These attributes are common among all event categories. Attributes that are specific to a particular event category are not part of the present document. For example, *perceivedSeverity* is an attribute specific for alarm event category. This attribute is not defined in the document but in Alarm IRP TS 32.111-2.

+### **10.9.10 TS 32.106-5 Telecommunication Management; Configuration Management; Part 5: Basic Configuration Management IRP information model (including NRM) version 1**
+
+The document (Basic Configuration Management (CM) IRP: Information Model) defines an Integration Reference Point (IRP) through which an 'IRPAgent' (typically an Element Manager or Network Element) can communicate basic Configuration Management related information to one or several 'IRPManagers' (typically Network Managers). This version of the IRP is mainly intended for "passive management" of high-level network configuration and status information as required by a Network Manager.
+
+The document is divided into three main parts:
+
+- Specifies a generic IRP Information Service with operations and notifications to be used by an 'IRPManager' to retrieve information on managed objects maintained by an 'IRPAgent'.
+- Specifies a generic Network Resource Model, NRM (also referred to as a Management Information Model – MIM) with definitions of Managed Object Classes.
+
+- Defines the UMTS management NRM by reusing this generic model either by direct reuse or subclassing.
+
+The Configuration Management (CM) area is very large. The intention is to split the specification of the related interfaces in several IRPs. In addition to the subject IRP, it is expected that IRPs will be defined for functional areas like Security management, Software management, Network & Service provisioning, etc. An important aspect of such a split is that the Network Resource Models (NRMs) defined in different IRPs are consistent. The Basic CM IRP here provides a base for all CM-related resource modelling.
+
+To summarize, the Basic CM IRP has three main purposes:
+
+- 1) To define an interface for retrieval of Configuration Management information;
+- 2) To define a generic Network Resource Model that constitutes a base from which other (more specialized) resource models can inherit; and
+- 3) To define the applied UMTS management Network Resource Model.

+#### 10.9.13 TS 32.106-8 Telecommunication Management; Configuration Management; Part 8: Name convention for Managed Objects
+
+A more detailed background and introduction of the IRP concept is given in TS 32.101 and TS 32.102.
+
+To perform network management tasks, co-operating applications require identical interpretation of names assigned to network resources under management. Such names are required to be unambiguous as well. The present document recommends one name convention for network resources under management in the IRP context.
+
+To facilitate integration of network management information obtained via multiple IRPs of different technologies such as CMIP and CORBA, identical network resource name semantics must be conveyed in all IRPs. The document specifies one such name convention.

+#### 10.9.14 TS 32.111-1 Telecommunication Management; Fault Management; Part 1: 3G fault management requirements
+
+The document specifies the overall requirements for 3G Fault Management (FM) as it applies to the Network Elements (NE), Element Manager (EM) and Network Manager (NM).
+
+This document defines the FM concept and functional requirements for the detection of faults and the generation, collection and presentation of alarms, operational state data and test results across 3G systems. These functions are described on a non-formal level since the formal standardization of these functions across the different vendors' equipment is not required. The functional areas specified in the present document cover:
+
+- Fault surveillance and detection in the NEs;
+- Notification of alarms (including alarm cease) and operational state changes;
+
+- Retrieval of current alarms from the NEs;
+- Fault isolation and defence mechanisms in the NEs;
+- Alarm filtering
+- Management of alarm severity levels;
+- Alarm and operational state data presentation and analysis at the Operations System (OS);
+- Retention of alarm and operational state data in the NEs and the OS; and
+- The management of tests.
+
+Any (re)configuration activity exerted from the EM as a consequence of faults will not be subject of the present document; these are described in TS 32.106.
+
+This document also defines the functional requirements for the standard Itf-N, for the purpose of Fault Management of 3G networks, as seen from the Network Manager (NM). The Itf-N is fully standardized so as to connect systems of any vendor to the NM via this interface.

+#### 10.9.15 TS 32.111-2 Telecommunication Management; Fault Management; Part 2: Alarm Integration Reference Point: Information Service
+
+The document (TS 32.111 Part-2) defines the Alarm Integration Reference Point (IRP) Information Service (IS), which addresses the alarm surveillance aspects of Fault Management (FM), applied to the N Interface between EM-NM and NE-NM.
+
+The purpose of the Alarm IRP is to define an interface through which a "system" (typically a Network Element Manager or a Network Element) can communicate alarm information for its managed objects to one or several Manager Systems (typically Network Management Systems).
+
+The Alarm IRP IS defines the semantics of alarms and the interactions visible across the reference point in a protocol neutral way. It defines the semantics of the operations and notifications visible in the IRP. It does not define the syntax or encoding of the operations, notifications and their parameters.

+
+### 10.10.1 TS 33.102 Security architecture
+
+This specification defines the security architecture, i.e., the security features and the security mechanisms, for the third generation mobile telecommunication system.
+
+A security feature is a service capability that meets one or several security requirements. The complete set of security features address the security requirements as they are defined in "3G Security: Threats and Requirements" (TS 21.133) and implement the security objectives and principles described in TS 33.120. A security mechanism is an element that is used to realize a security feature. All security features and security mechanisms taken together form the security architecture.
+
+An example of a security feature is user data confidentiality. A security mechanism that may be used to implement that feature is a stream cipher using a derived cipher key.
+
+This specification defines 3G security procedures performed within 3G capable networks (R99+), i.e. intra-UMTS and UMTS-GSM. As an example, UMTS authentication is applicable to UMTS radio access as well as GSM radio access provided that the serving network node and the MS are UMTS capable.

+### 10.10.2 TS 33.103 Security Integration Guidelines
+
+This technical specification defines how elements of the 3G-security architecture is to be integrated into the following entities of the system architecture.
+
+- Home Environment Authentication Centre (HE/AuC);
+- Serving Network Visited Location Register (VLR/SGSN);
+- Radio Network Controller (RNC);
+- Mobile station User Identity Module (UIM);
+- Mobile Equipment (ME).
+
+This specification is derived from 3G "Security architecture" TS 33.102.
+
+The structure of this technical specification is a series of tables, which describe the security information and cryptographic functions to be stored in the above entities of the 3G systems.
+
+For security information, this is in terms of multiplicity, lifetime, parameter length and whether mandatory or optional.
+
+For the cryptographic functions, the tables also include an indication of whether the implementation needs to be standardized or whether it can be proprietary.
+
+The equivalent information for the alternative Temporary Key proposal is included in an appendix to this document.

+
+## **Summary**
+
+This Recommendation describes the messages, parameters and the signalling information contained within parameters used by the Bearer Independent Call Control (BICC) protocol and the ISDN user part, and their functions.
+
+###### **Source**
+
+ITU-T Recommendation Q.1902.2 was prepared by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 2 July 2001.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+## ITU-T Recommendation Q.1902.2
+
+## Bearer Independent Call Control protocol (Capability Set 2) and Signalling System No. 7 ISDN user part: General functions of messages and parameters
+
+## 1 Scope
+
+This Recommendation describes the elements of signalling information used by the Bearer Independent Call Control protocol and the ISDN user part and their functions. The encoding of these elements, the format of the messages in which they are conveyed, their applicability to the two protocols, and an indication of whether or not they are for national use, are described in ITU-T Rec. Q.1902.3. Throughout this Recommendation where a message, a parameter or parameter information relates to either physical circuits controlled by the ISDN user part or the BICC protocol call instances the notation "circuit/CIC" is used. Also, a generic term "node" is used to refer to signalling entities in either the ISUP (i.e. an exchange) or the BICC network (i.e. either an SN or an CMN) whenever a message, a parameter or parameter information is applicable to either.

+## 5 Signalling messages
+
+**5.1 Address Complete Message (ACM):** A message sent in the backward direction indicating that all the address signals required for routing the call to the called party have been received.
+
+**5.2 Answer Message (ANM):** A message sent in the backward direction indicating that the call has been answered. In semi-automatic working, this message has a supervisory function. In automatic working, this message is used in conjunction with charging information in order to:
+
+- start metering the charge to the calling subscriber (see ITU-T Rec. Q.28); and
+- start measurement of call duration for international accounting purposes (see ITU-T Rec. E.260).
+
+**5.3 Application Transport Message (APM):** A message sent in either direction to convey application information using the Application Transport mechanism.
+
+**5.4 Blocking message (BLO):** A message sent only for maintenance purposes to the exchange at the other end of a circuit, to cause an engaged condition of that circuit for subsequent calls outgoing from that exchange. When a circuit is used in the bothway mode of operation, an exchange receiving the blocking message must be capable of accepting incoming calls on the concerned circuit unless it has also sent a blocking message. Under certain conditions, a blocking message is also a proper response to a reset circuit message.
+
+**5.5 Blocking Acknowledgement message (BLA):** A message sent in response to a blocking message indicating that the circuit has been blocked.
+
+**5.6 Call Progress message (CPG):** A message, sent in either direction during the setup or active phase of the call, indicating that an event, which is of significance, and should be relayed to the originating or terminating access, has occurred.
+
+**5.7 Charge information message (CRG):** Information sent in either direction for accounting and/or call charging purposes.
+
+**5.8 Circuit/CIC Group Blocking message (CGB):** A message sent to the node to permit the switching equipment or maintenance system to remove from (and return to) traffic a group of circuits/CICs. A node receiving a Circuit/CIC group blocking message must be able to accept incoming calls on the group of blocked circuits/CICs unless it has also sent a Circuit/CIC group blocking message.
+
+**5.9 Circuit/CIC Group Blocking Acknowledgement message (CGBA):** A message sent in response to a Circuit/CIC group blocking message to indicate that the requested group of circuits/CICs has been blocked.
+
+**5.10 Circuit/CIC Group Reset message (GRS):** A message sent to release an identified group of circuits/CICs when, due to memory mutilation or other causes, it is unknown whether for example, a release or release complete message is appropriate for each of the circuits/CICs in the group. If at the receiving end a circuit/CIC is remotely blocked, reception of this message should cause that condition to be removed.
+
+**5.11 Circuit/CIC Group Reset Acknowledgement message (GRA):** A message sent in response to a Circuit/CIC group reset message indicating that the requested group of circuits/CICs has been reset. The message also indicates the maintenance blocking state of each circuit/CIC.
+
+**5.12 Circuit/CIC Group Unblocking message (CGU):** A message sent to the node to cause cancellation in a group of circuits/CICs of a blocked condition invoked earlier by a Circuit/CIC group blocking message.

+- 5.18a Continuity message (COT) (BICC):** A message sent in the forward direction indicating that the establishment of the bearer is complete up to and including the SN sending the COT message.
+- 5.19 Continuity Check Request message (CCR):** A message sent by an exchange for a circuit on which a continuity check is to be performed, to the exchange at the other end of the circuit, requesting continuity checking equipment to be attached.
+- 5.20 Facility Accepted message (FAA):** A message sent in response to a facility request message indicating that the requested facility has been invoked.
+- 5.21 Facility message (FAC):** A message sent in either direction at any phase of the call to request an action at another node. The message is also used to carry the results, error or rejection of a previously requested action.

+- 5.34 Pass-Along Message (PAM):** A message that may be sent in either direction to transfer information between two signalling points along the same signalling path as that used to establish a physical connection between those two points.
+- 5.35 Pre-release Information message (PRI):** A message to be used with the Release message for the transport of information which cannot be sent in the Release message due to the compatibility rules (see ITU-T Rec. Q.1902.4 for BICC and ITU-T Rec. Q.764 for ISUP).
+- 5.36 Release message (REL):** A message sent in either direction to indicate that the circuit/CIC is being released due to the reason (cause) supplied and is ready to be put into the idle state on receipt of the Release Complete message. Where the call is to be redirected the message will also carry the redirection number.
+- 5.37 Release Complete message (RLC):** A message sent in either direction in response to the receipt of a Release message, or if appropriate to a Reset circuit message, when the circuit/CIC concerned has been brought into the idle condition.
+- 5.38 Reset Circuit/CIC message (RSC):** A message sent to release a circuit/CIC when, due to memory mutilation or other causes, it is unknown whether for example, a Release or a Release complete message is appropriate. If, at the receiving end, the circuit/CIC is remotely blocked, reception of this message should cause that condition to be removed.
+- 5.39 Resume message (RES):** A message sent in either direction indicating that the calling or called party, after having been suspended, is reconnected.
+- 5.40 Segmentation Message (SGM):** A message sent in either direction to convey an additional segment of an overlength message.
+- 5.41 Subsequent Address Message (SAM):** A message that may be sent in the forward direction following an initial address message, to convey additional called party number information.
+- 5.42 Subsequent Directory Number message (SDM):** A message that may be sent in the forward direction following an Initial address message, to convey additional called party number information, when the called party number in the Initial address message was contained in the Called Directory Number parameter.

+- 6.15 called IN number:** Information indicating the number which was received in the SSP as called party number in IAM and SAM messages.
+
+**6.16 called party number:** Information to identify the called party.
+
+**6.17 calling geodetic location:** Information that indicates the geodetic location of the calling party. The reference system for the coding is the World Geodetic System 1984, (WGS-84). The origin of the WGS-84 coordinate system is the geometric centre of the WGS-84 ellipsoid. The ellipsoid is constructed by the rotation of an ellipse around the minor axis that is oriented in the north-south direction. The rotation axis is the polar axis of the ellipsoid, and the plane orthogonal to it and including the centre of symmetry is the equatorial plane.
+
+The relevant dimensions are as follows:
+
+Major Axis (a) = 6 378 137 m
+
+Minor Axis (b) = 6 356 752.314 m
+
+Coordinates are then expressed in terms of longitude and latitude relevant to this ellipsoid. The range of longitude is  $-180^\circ$  to  $+180^\circ$ , and the range of latitude is  $-90^\circ$  to  $+90^\circ$ .  $0^\circ$  longitude corresponds to the Greenwich Meridian, and positive angles are to the East, while negative angles are to the West.  $0^\circ$  latitude corresponds to the equator, and positive angles are to the North, while negative angles are to the South. Altitudes are defined as the distance between the ellipsoid and the point, along a line orthogonal to the ellipsoid.
+
+**6.18 Calling Party Geodetic Velocity Information:** Information that indicates velocity information associated with the Calling Party Geodetic Information.
+
+**6.19 calling party number:** Information sent in the forward direction to identify the calling party.
+
+**6.20 calling party's category:** Information sent in the forward direction indicating the category of the calling party and, in case of semi-automatic calls, the service language to be spoken by the incoming, delay and assistance operators.
+
+**6.21 carrier selection information:** Information sent in the forward direction to indicate the method (namely call per call or preselection) being used to invoke carrier selection.
+
+**6.22 cause indicators:** Information sent in either direction indicating the reason for sending the message (e.g. release message).

+
+## **Summary**
+
+This Recommendation defines the signalling interworking between the Bearer Independent Call Control (BICC) protocol and H.323. It defines in particular the signalling interworking between the BICC protocol and the H.225.0 Multimedia Call Control protocol based on the interworking between H.225.0 and the ISDN User Part (ISUP) protocol of Signalling System No. 7.
+
+## **Source**
+
+ITU-T Recommendation Q.1912.3 was prepared by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 2 July 2001.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups, which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# **Interworking between H.323 and the Bearer Independent Call Control protocol**
+
+## **1 Scope**
+
+This Recommendation defines the signalling interworking between the Bearer Independent Call Control (BICC) protocol and H.323.
+
+It defines in particular the signalling interworking between the BICC protocol and the H.225.0 Multimedia Call Control protocol in an H.323 network based on the interworking between H.225.0 and the ISDN User Part (ISUP) protocol of Signalling System No. 7.
+
+The interworking between H.245 and BICC is for further study (some aspects are addressed in 6.3 and Appendix I).
+
+BICC is the protocol defined in ITU-T Recommendations Q.1902.1 to Q.1902.4 [5]. The Multimedia Call Control protocol is defined in ITU-T H.225.0 [1] for a network in accordance with ITU-T H.323 [3]. ISUP is the protocol defined in ITU-T Recommendations Q.761 to Q.764 [4].
+
+The description of the signalling interworking between the H.225.0 Multimedia Call Control protocol and the BICC protocol in this Recommendation builds upon:
+
+- The signalling interworking between the H.225.0 Multimedia Call Control protocol and the ISDN User Part (ISUP) protocol of Signalling System No. 7 as defined in Annex C/H.246 [2].
+- The signalling interworking between the Bearer Independent Call Control (BICC) protocol and the ISDN User Part (ISUP) protocol of Signalling System No. 7 as defined in ITU-T Q.1912.1 [6].
+
+The scope of this Recommendation with regard to the signalling interworking between the H.225.0 Multimedia Call Control protocol and the BICC protocol is as shown in Figure 1.

+# 5 General considerations
+
+This clause describes the interworking principle between H.225.0 and BICC based on the interworking between H.225.0 and ISUP concatenated with the interworking between ISUP and BICC. This refers to the necessary mapping of signalling information to achieve connectivity and functionality between an H.323 network and a BICC network. Figure 2 provides the functional grouping of the interworking functions involved following the half call model description technique for BICC.

+## **6 Interworking considerations**
+
+## **6.1 General**
+
+The interworking between H.225.0 and BICC shall act according to the interworking between H.225.0 and ISUP in Annex C/H.246 [3], and the additional interworking statements in the Implementors Guide for H.323, H.225.0, H.245, H.246, H.283, H.235, H.450-series and H.341 Recommendations in ITU-T Implementors Guide [8], concatenated with the interworking between ISUP and BICC in ITU-T Q.1912.1 [6].
+
+## **6.2 Prevention of speech clipping**
+
+For an incoming H.323 call for which the incoming bearer is not established yet in the H.323 network, the Continuity Indicator in the Nature of Connection Indicators parameter in the IAM in BICC shall be set to indicate "COT to be expected" if the ISN is aware that the call establishment procedures in ITU-T H.245 [9] can take place in the H.323 network without waiting until an ACM message is received in BICC (Note).
+
+The Continuity message, with the Continuity Indicators parameter set to "Continuity" shall be sent in BICC upon successful completion of the incoming H.323 bearer set-up procedures.
+
+NOTE – In some H.323 implementations, the H.245 call establishment procedures cannot be initiated before an ACM is received from the BICC network (because the H.245 procedures are not handled until a CONNECT is received or because a CALL PROCEEDING message is not generated before an ACM is received). In such cases, speech clipping cannot be prevented. H.323 networks using such implementations should not be interconnected to BICC networks. The H.245 call establishment procedures shall be initiated as soon as possible on the H.323 side.
+
+If the Fast Connect procedure is used on the H.323 side, the ISN shall first check that the bearer establishment can be successfully completed according to the proposals received in the fastStart element of the SETUP message received from the H.323 side, before sending the IAM in BICC.
+
+## **6.3 Codec negotiation and out-of-band transport of DTMF and tone information**
+
+Interworking procedures related to codec negotiation (including mid-call codec modification and mid-call codec negotiation procedures) and out-of-band transport of DTMF and tone information have also to be considered in case of interworking between an H.323 network and a BICC network. These procedures require the definition of interactions between the BICC protocol and some parts of the H.245 protocol. The accurate definition of these procedures is for further study. Appendix I provides guidelines for the implementation of the end-to-end codec negotiation procedures through a BICC and H.323 network.
+
+## **6.4 Interworking of ISDN supplementary services**
+
+Please note that the interworking of ISDN supplementary services (ITU-T H.450.x-series [7]) is for further study.
+
+# Guidelines BICC/H.323 interworking for end-to-end codec negotiation
+
+## I.1 Introduction
+
+The H.245 capability exchange procedures are more complex than the BICC codec negotiation procedures since H.323 nodes have the possibility to separately indicate receive and transmit capabilities, as well as various combination of modes in which the node can operate simultaneously. A different codec can be selected for each unidirectional media channel in H.323.
+
+As the same codec is used for transmission and reception in a BICC network, only the codecs which are proposed by the H.323 network for reception and transmission will be included in the initial BICC Supported Codecs list used to perform the BICC codec negotiation. This principle is generally applied in the procedures defined below although it is not explicitly mentioned.
+
+## I.2 H.323 to BICC interworking
+
+![Diagram showing the network architecture for H.323 to BICC interworking. It consists of three nodes: Node A, ISN B, and Node C. Node A is connected to the H.323 network, which is connected to the BICC network, which is connected to Node C. ISN B is the interface between the H.323 and BICC networks.](5e92d9e8e9ce204e405bff2367f88176_img.jpg)

+
+### I.2.1 If the H.245 procedures are used (with a separate H.245 control channel or using the H.245 encapsulation method)
+
+- 1) If the capabilities supported by the preceding H.323 node (node A) are received by the ISN (in an H.245 TerminalCapabilitySet message) before the IAM is sent on the outgoing side, the Supported Codec List sent in the IAM is derived from the capability structures contained in the received TerminalCapabilitySet message by deleting the codecs that cannot be used for the call (not offered by the ISN) and adding (with a lower priority) the codecs that can be used for the call (proposed by the ISN) but were not indicated in the received capabilities from the preceding H.323 node (node A).
+
+The ISN shall wait until an APM with the selected codec is received before indicating its capabilities to the preceding H.323 node (node A).
+
+- If the Selected Codec received in the APM was contained in the received TerminalCapabilitySet message from the preceding H.323 node (node A), the H.245 TerminalCapabilitySet message sent by the ISN shall only contain the selected codec received in the BICC APM. The end-to-end codec negotiation procedures are successfully completed. The codec selected by the ISN on the H.323 side (sent in the OpenLogicalChannel message) is the codec resulting from the BICC negotiation procedure.
+- If the Selected Codec received in the APM does not belong to the capabilities indicating by the preceding H.323 node (node A), a transcoder shall be used.
+
+- 2) If the capabilities supported by the preceding H.323 node (node A) are not received by the ISN (in an H.245 TerminalCapabilitySet message) before the IAM is sent on the outgoing side, the Supported Codec List is constructed in the ISN as described in ITU-T Q.1902.4 (SN initiating codec negotiation). The ISN waits until the codec negotiation procedure is completed on the BICC side before indicating its capabilities to the preceding node (node A).
+
+When the APM with the selected codec is received by the ISN:
+
+- The ISN sends a TerminalCapabilitySet message containing the codecs that can be used for the call (codecs supported by the ISN), allocating the highest priority to the BICC selected codec and the other codecs of the Available codec List.
+- If the codec selected by the preceding H.323 node (node A) (received in the H.245 OpenLogicalChannel message) is the BICC Selected codec, end-to-end negotiation procedures are successfully completed. The codec selected by the ISN on the H.323 side (sent in the OpenLogicalChannel message) is the same as the codec selected by the preceding H.323 node.
+- If the codec selected by the preceding H.323 node (node A) (received in the H.245 OpenLogicalChannel message) is not the BICC Selected codec but belongs to the BICC Available codec List, the BICC Modification procedure shall be applied on the BICC side: the newly selected codec is the codec selected by node A and the new Available codec List is the old one from which the codecs not supported by node A are deleted. The codec selected by the ISN on the H.323 side (sent in the OpenLogicalChannel message) is the same as the codec selected by the preceding H.323 node.
+- If the codec selected by the preceding H.323 node (node A) does not belong to the BICC Available codec List, a transcoder shall be used.
+
+### I.2.2 If Fast Connect procedure is used
+
+The Supported Codec List sent in the IAM is derived from the OpenLogicalChannel proposals received in the fastStart element of the Setup message by deleting the codecs which are not supported for the call (the codecs are listed in the same priority order as received in the fastStart element) and adding (with a lower priority) the codecs that can be used for the call but were not proposed in the received fastStart element.
+
+The backward APM with the Selected codec is awaited before the fastStart element is sent back by the ISN.
+
+- If the Selected Codec received in the APM was proposed in the received fastStart element, the ISN sends a fastStart element selecting amongst the OpenLogicalChannel proposals containing the Selected codec received in the APM. The end-to-end codec negotiation is successfully completed.
+- If the Selected Codec received in the APM was not proposed in the received fastStart element, a transcoder shall be used.

+
+![Diagram illustrating BICC to H.323 interworking. It shows three nodes: Node A, ISN B, and Node C. Node A is connected to the BICC network, which is connected to the H.323 network, which is connected to Node C. ISN B is located at the boundary between the BICC and H.323 networks.](853f59c89931a666c07903b31d098277_img.jpg)

+
+### **I.3.1 If H.245 procedures are used (with a separate H.245 control channel or using the H.245 encapsulation method)**
+
+It may not be possible to wait until the capabilities of node C are received before selecting the codec on the BICC side: H.245 procedures may only begin in the H.323 network when a H.225.0 CONNECT message is sent (when an answer is received from the called party) whereas the BICC codec negotiation procedures must be completed before the ACM is sent. It is therefore preferable to complete the BICC codec negotiation procedures independently of the H.323 procedures on the outgoing side.
+
+- The ISN waits until a TerminalCapabilitySet message is received from the succeeding H.323 node.
+- If the BICC Selected codec is supported by the succeeding H.323 node (node C), end-to-end negotiation procedures are successfully completed. The ISN sends a TerminalCapabilitySet containing the BICC selected codec only. The OpenLogicalChannel message which will be sent by the ISN shall contain this same BICC selected codec. The end-to-end codec negotiation procedures are successfully completed.
+- If the BICC selected codec does not belong to the list of codecs supported by the succeeding H.323 node, the ISN selects the codec with the highest priority in the BICC Available Codecs List which is also supported by the succeeding H.323 node. The ISN sends a TerminalCapabilitySet containing the BICC selected codec only. The OpenLogicalChannel message which will be sent by the ISN shall contain this same BICC selected codec. The BICC modification procedure is applied on the BICC side: the newly selected codec is the codec selected by the ISN and the new Available codec List is the old one from which the codecs not supported by the succeeding H.323 (node C) are deleted.
+- If no codec of the BICC Available Codecs List is supported by the succeeding H.323 node, a transcoder shall be used.
+
+#### **I.3.2 If Fast Connect procedure is used**
+
+The OpenLogicalChannel proposals sent in the fastStart element of the SETUP message contains the codecs that can be used for the call (supported by the ISN). The BICC Selected codec and the codecs of the BICC Available codecs List resulting from the BICC negotiation procedure are proposed with the highest priority.
+
+- If the codec selected by the succeeding H.323 node (node C) (received in the selected OpenLogicalChannel indicated in the fastStart element) is the BICC Selected codec, end-to-end negotiation procedures are successfully completed.
+- If the codec selected by the succeeding H.323 node (node C) (received in the OpenLogicalChannel contained in the fastStart element) is not the BICC Selected codec but belongs to the BICC Available codec List, the BICC Modification procedure shall be applied on the BICC side: the newly selected codec is the codec selected by the succeeding H.323 node (node C) and the new Available codec List is the old one from which the codecs which were proposed with a higher priority than the H.323 Selected codec (codecs not supported by the succeeding H.323 node (node C)) are deleted.
+- If the codec selected by the succeeding H.323 node (node C) does not belong to the BICC Available Codecs List, a transcoder shall be used.

+
+## **Summary**
+
+This Recommendation defines the signalling interworking for 64 kbit/s ISDN Circuit Mode Services between Digital Subscriber Signalling System No. 2 (DSS2) and Bearer Independent Call Control (BICC).
+
+### **Source**
+
+ITU-T Recommendation Q.1912.4 was prepared by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 2 July 2001.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+## **Interworking between Digital Subscriber Signalling System No. 2 and the Bearer Independent Call Control protocol**
+
+## **1 Scope**
+
+This Recommendation defines the signalling interworking between the Bearer Independent Call Control (BICC) protocol and Digital Subscriber Signalling System No. 2 (DSS2). In this Recommendation, interworking is defined through the relationships in existing Recommendations for interworking between DSS2 and B-ISUP, in addition to interworking between B-ISUP and ISUP.
+
+BICC is the protocol defined in ITU-T Q.1902.1 to Q.1902.4 [6]. DSS2 is defined by ITU-T Q.2931 [15], Q.2932.1 [17], Q.2951 [18], Q.2951.9 [19], Q.2957 [20], Q.2941.2 [21]. B-ISUP is the protocol defined in ITU-T Q.2761 to Q.2764 [14]. ISUP is the protocol defined in ITU-T Q.761 to Q.764 [4].
+
+This Recommendation builds on:
+
+- The signalling interworking between existing DSS2 and the B-ISDN User Part (B-ISUP) protocol as defined in various ITU-T Recommendations.
+- The signalling interworking between existing B-ISUP signalling systems and the ISDN User Part (ISUP) protocol of Signalling System No. 7 as defined in various ITU-T Recommendations.
+- The signalling interworking between the Bearer Independent Call Control (BICC) protocol and the ISDN User Part (ISUP) protocol of Signalling System No. 7 as defined in ITU-T Q.1912.1 [7].
+
+The scope of this Recommendation as shown in Figure 1.

+## 5 General considerations
+
+This Recommendation specifies the interworking principle between BICC and Digital Subscriber Signalling System No. 2. The interworking is defined by the concatenation of information provided by several ITU-T Recommendations that are part of a set of interlocking B-ISDN service and signalling Recommendations that comprise broadband signalling capabilities. Figure 2 provides the functional grouping of the entities involved.
+
+The B-ISDN access signalling DSS2 is specified in ITU-T Q.2931 [16]. The interworking between DSS2 for 64 kbit/s circuit mode services and BICC shall act according to the interworking between DSS2 and B-ISUP defined in ITU-T Q.2650 [10] and the interworking between B-ISUP and ISUP defined in ITU-T Q.2660 [11].
+
+The ISDN circuit mode services are interworked following, in sequence, the procedures in ITU-T Q.2650 and Q.2660. The reader may find it helpful to read ITU-T Q.699 [3] for the detailed description of how indicator values are used when interworking 64 kbit/s ISDN Circuit Mode Services.

+
+The diagram illustrates the functional description of the interworking configuration. It features a large rectangular box labeled "CSF-N" at the top left. Inside this box, five smaller rectangular boxes are arranged horizontally from left to right: "DSS2 Access", "Q.2650", "Q.2660", "Q.1912.1", and "BICC". These internal components are interconnected by double-headed arrows. The "DSS2 Access" box has a double-headed arrow pointing to the left, outside the CSF-N box. The "BICC" box has a double-headed arrow pointing to the right, outside the CSF-N box. Above the CSF-N box, there are two horizontal double-headed arrows. The first is labeled "Half call" and spans from the left edge of the CSF-N box to a vertical grey line positioned between the "Q.1912.1" and "BICC" boxes. The second is also labeled "Half call" and spans from the vertical grey line to the right edge of the CSF-N box. In the bottom right corner, outside the CSF-N box, the text "T11111980-01" is present.

+## **ITU-T Recommendation Q.1980.1**
+
+# **The Narrowband Signalling Syntax (NSS) – Syntax definition**
+
+## **Summary**
+
+This Recommendation describes a Narrowband Signalling Syntax (NSS) to provide a normalized set of telephony parameters. NSS enables mapping from multiple telephony protocols in use today into a common parameter set.
+
+## **Source**
+
+ITU-T Recommendation Q.1980.1 was approved on 10 December 2004 by ITU-T Study Group 11 (2005-2008) under the ITU-T Recommendation A.8 procedure.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right.

+# 3 Definitions
+
+This Recommendation defines the following terms:
+
+**3.1 compatibility parameter:** A compatibility parameter is a NSS parameter used to carry unrecognized syntax objects and requiring the PRN parameter for interpretation. The set of compatibility parameters includes FDC, UFC, PCI, and MCI.
+
+NOTE – The ATP parameter also requires the PRN parameter for interpretation.
+
+**3.2 mappable parameter:** An ISUP/BICC parameter which satisfies the following conditions with respect to the protocol transporting the NSS body:
+
+- every field in the ISUP/BICC parameter is accounted for by a field or combination of fields in the encapsulating protocol;
+- every potential value of the ISUP/BICC field is accounted for by a value of the corresponding field(s) in the encapsulating protocol; and
+- the original value of every ISUP/BICC field can be recovered when the encapsulating protocol alone (disregarding any encapsulated NSS or ISUP/BICC) is mapped back to the same variant of ISUP/BICC as was mapped into the encapsulating protocol at the NSS-originating node.
+
+**3.3 NSS message:** A NSS message is a body composed of a contiguous set of text lines as defined in clause 5.

+# 5 Message and parameter syntax overview
+
+The general rules for NSS message, parameter, and field formats are specified in this clause.
+
+## 5.1 Character set
+
+NSS messages are composed of printable IA5 (i.e., 7-bit US ASCII) characters plus carriage return (CR = x0D) and line feed (LF = x0A). Alphabetic characters are case sensitive. The case rules are described in this clause and in 5.2.
+
+Values potentially requiring the representation of information lying outside this character set shall be presented as a sequence of one or more binary octets, expressed as a series of one or more pairs of characters ("0"-"9", "A"-"F") without a preceding "x" representing the binary octets as hexadecimal values. The characters "A" through "F" must be upper case. The ordering of the binary octets in a given value is defined by the source protocol. The resulting sequence of character pairs will be placed into an NSS value field with no leading "x" character in that same order. The first character of each pair represents the most significant four bits of the binary octet being expressed. If an octet of the source protocol contains bits which do not belong to the field or sub-field value being encoded, these bits shall be set to zero before applying the hexadecimal encoding.
+
+NOTE – The ordering of bits within individual octets as represented by the hexadecimal encoding is the reverse of their order of transmission in the source protocol. See 1.9/Q.763.
+
+Clauses 7.3 and 7.4 indicate for each field or subfield value whether the direct or ASCII-hexadecimal representation is used.
+
+The CR and LF characters are reserved for use together as line termination. See 5.2.1.
+
+The "," and "=" characters are reserved for use as separators. Parentheses "(" and ")" and braces "{" and "}" are reserved for use as group delimiters. The application of these reserved characters is described in 5.2.
+
+The "\" character is reserved for use as an escape mechanism and must be placed immediately before any "," or "=" or "(" or ")" or "{" or "}" or CR or LF or "\" character found in a field value during parameter construction. During parsing, each first encounter of an "\" character is not used as part of the field value and the character following the "\" is treated as part of the field value.
+
+## 5.2 Structure
+
+### 5.2.1 NSS message
+
+A NSS message is composed of a sequence of lines, each beginning with a sequence of three upper-case letters followed by a comma and ending with a carriage return – line feed sequence (x0Dx0A).
+
+Except for the Message Identifier line, the initial sequence of letters on a line identifies a parameter. On the Message Identifier line, the initial sequence of letters identifies a message.
+
+The set of message identifiers defined in this Recommendation is listed in 6.2, "NSS message identifier codes".
+
+The set of parameter identifiers defined in this Recommendation is listed in 7.2, "NSS parameter codes".
+
+A NSS message begins with three mandatory NSS-specific parameters: Version (VER), Protocol Name/Version (PRN), and Message Identifier in that order. These are followed by zero or more other parameters.
+
+This Recommendation does not specify which additional parameters must be present in a NSS message, nor does it specify the order in which those parameter lines must appear. It is recommended that this order be the same as that of the corresponding parameters in the source protocol message.
+
+NOTE – It is expected that NSS messages will not include parameter lines derived from source protocol parameters that have been successfully mapped to the encapsulating protocol. Rules for interworking BICC and ISUP to the combination of SIP (RFC 3261) or ITU-T Rec. H.323 and NSS are not in the scope of this Recommendation.
+
+Multiple parameters of the same type indicate concurrent instances of a parameter within a single NSS message.
+
+### 5.2.2 NSS parameter line
+
+Each parameter identifier is followed by a sequence of fields. The set of fields that is required to be present for each parameter defined in this Recommendation and the order in which these fields must appear is specified in the applicable sub-clauses of Recommendation 7.3, "Detailed parameter descriptions", and 7.4, "BAT ASE parameters".
+
+Two successive fields are separated by a comma ",".
+
+### 5.2.3 NSS fields
+
+The type and the actual set of values permitted for each field is specified in the applicable sub-clause of Recommendation 7.3, "Detailed parameter descriptions" and of 7.4, "BAT ASE parameters".
+
+The value may be omitted if the field value is unknown, leaving only the separating comma if there is a following field. This is permitted only if the range of permissible values for the field includes "unknown". The decoding end must correspondingly interpret an empty field value as having the "unknown" value.
+
+Field values defined as literals in 7.3 must be transmitted exactly as defined, e.g., a field value of "0001" must not be transmitted as "1".
+
+For multiple groups of fields and values within some parameters, multiple iterations of the same element type or value may be enclosed by parentheses "(" and ")". Braces "{" and "}" denote a tuple of dissimilar elements. Commas must separate elements within each type of group. From the perspective of higher-level constructs, those groups are viewed as a single field value. Detailed descriptions are provided in those parameters where this applies, e.g., in 7.3.18, "Calling Geodetic Location (CGL)" and in 7.3.23, "Cause indicators (CAI)".
+
+## 5.3 NSS compact transmission mode
+
+The normal encoding of NSS requires that field values be presented without identifying tags. This is possible because all field values in a parameter have a fixed order.
+
+NOTE – For human display purposes, a "field-name=" construct may be inserted before each field value. Alphabetic characters within field names are always lower case. The field names for fields specified in this Recommendation are shown in 7.3, "Detailed parameter descriptions", to aid in readability, but are not transmitted. The corresponding ABNF for converting from the transmission mode to a display is shown in Appendix II.
+
+For an example of a NSS message in compact transmission mode, see Appendix I.
+
+# 6 Message definitions
+
+This clause describes the Message Identifiers supported by the NSS. Clause 7 describes all messages, parameters, and fields specifically introduced by the NSS protocol with both structure and intended use. Although this Recommendation provides detailed breakdowns of NSS parameter structure and field values, these must not be considered to be descriptions of the structure and use of existing ISUP messages, parameters, and fields.
+
+NOTE – It is intended that the procedures associated with parameters in NSS will be those applicable to the source protocol parameter from which they were mapped. This topic is not in the scope of this Recommendation.
+
+## 6.1 Unsupported messages
+
+There are no NSS equivalents for ISUP/BICC messages that do not have end-to-end significance, especially the TDM circuit management messages. Unrecognized NSS Message Handling (see 12.3) procedures can be used in the event that the such messages are required to be transmitted.
+
+## 6.2 NSS message identifier codes
+
+The following is the list of message names and their associated NSS Message Identifier codes. Parameter codes and Message Identifier codes share the same code space.

+
+# 7 Parameter definitions
+
+This clause describes the syntax, parameters, fields, and field values.
+
+## 7.1 Unsupported parameter disposition
+
+The parameter "End Of Optional Parameters" is derived from ISUP specifications. It is not supported in NSS because that role is superseded by the encoding rules defined in 5.2.1.
+
+## 7.2 NSS parameter codes
+
+The following list of parameter names is derived as a superset of ISUP and BICC parameters from the specifications identified in clause 2. The NSS-specific parameters are needed to address transparency issues.
+
+Parameter codes and Message Identifier codes share the same code space.

+Telecommunications vendors and operators may wish to use new or private network-specific parameters. In such cases, the parameter must use a three-letter code different from the above list and should encapsulate it within the Parameter Compatibility Information (PCI) parameter so that intermediate nodes are not burdened. Nodes that agree to use that parameter should also agree on PRN values to indicate what parameter set to expect.
+
+The order of the parameters detailed in the remainder of clause 7 follows the order in the above list. The following list is ordered by NSS code to aid in finding the full parameter name.

+## 7.3 Detailed parameter descriptions
+
+The designation "a" means all possible characters allowed in 5.1, unless otherwise constrained by the field description. The designation "d" means only characters 0-9 are used. The designation "h" means that the field or subfield is to be hexadecimal-encoded.
+
+The first field value for most fields will be the "unknown" value. "Unknown" means that the information was absent or unavailable at the source of the NSS encoding.
+
+The left-hand columns in the following clauses are **literal** values to be used as codepoints. The Format lines show "<tag>=" preceding the field values; however, these field names (tags) are not transmitted in the compact encoding used on the wire.
+

+1\*d - This field value is the decimal equivalent of the 23-bit binary value N, that when multiplied by 90 and divided by  $2^{23}$  produces degrees and fraction of degrees to multiple decimal places of precision. This note applies to all latitude fields in this parameter.  
+Example: 111 0000 0000 0000 0000 0000 = 7,340,032  
+ $x \ 90 = 660,602,880 / 2^{23} = 78.75$  degrees.  
+In other words,  $N/(2^{23})$  produces a fraction  $0 \leq X < 1$  of the total 90 degrees.

+
+The value of the subfield may also be a tuple of values. In that case, that one subfield takes the form of:

+
+Note that any collective set of related values, be it di={ } or the set composing the subfield value {part1, part2, part3} are enclosed with braces. In contrast, parentheses () are used to enclose multiple instances of the same type of value. Combined example:  
+ , di={val1, ({x1, x2, x3}, {y1, y2, y3}), , , , , , , , , } with 2 instances of value 2 named x and y, each composed of 3 sub-subfields.
+
+The twelve subfields according to Q.850 may occur independently. Their values are defined in detail in the grammar in Annex A.
+
+When no diagnostics are included, the compact form uses only one comma: ",di=" becomes "," -- NOT ",di={ , , , , , , , , , , }" and ",{ , , , , , , , , , , }".

Once created, TID must not be modified by subsequent nodes. This is used for message event correlation across switching nodes but does not require call state history to be maintained to generate this parameter. The distinction between TID and GCI is that TID typically involves tracing the message only, whereas the GCI may span multiple messages and multiple call legs.

+
+# 8 MIME encoding of NSS body
+
+The following clauses describe the header elements specific to MIME (specified in RFC 2045) that may be used to encapsulate NSS within a SIP message. The MIME headers must be used with SIP messages. MIME headers should not be used with H.323 messages, since ITU-T Rec. H.323 has its own encapsulation mechanisms.
+
+## 8.1 MIME-Version header field
+
+The MIME-Version header field uses a version number to declare a message to be conformant with MIME and allows mail processing agents to distinguish between such messages and those generated by older or non-conformant software, which are presumed to lack such a field.
+
+## 8.2 Content-Type header field
+
+The Content-Type header field for the NSS MIME body is "application/nss".
+
+In NSS, the optional 'base' parameter is not used. Instead, the source protocol identity is carried in the NSS PRN parameter.
+
+In NSS, the optional 'version' parameter is not used. Instead, the version of NSS used is carried in the NSS VER parameter. This enables direct transfer from SIP networks to H.323 networks, which do not use the MIME headers in encoding.
+
+The 'charset' parameter indicates that the contents of the MIME body part will only use 7-bit US-ASCII encoding. In some NSS parameters, one-byte ASCII characters are used to represent the hexadecimal equivalent of one nibble binary values. The 7-bit encoding enables transport through text-based e-mail at the cost of doubling bandwidth. That binary-to-ASCII encoding transformation is usually for compatibility parameters, which are of limited size.
+
+## 8.3 Content-Transfer-Encoding header field
+
+A Content-Transfer-Encoding header field is used to indicate both the encoding transformation that was applied to the body and the domain of the result. Encoding transformations other than the identity transformation are usually applied to data in order to allow it to pass through mail transport mechanisms which may have data or character set limitations.
+
+The mechanism employed for content transfer encoding could be a choice from "7bit", "8bit", "binary", "quoted-printable", "base64", ietf-token, or x-token. ISUP messages are natively binary, but NSS will use US-ASCII to represent all parameter tags and values. Binary values are represented by ASCII representation of the hexadecimal equivalent. This header is optional for NSS.
+
+## 8.4 Content-Disposition header field
+
+The Content-Disposition header (specified in RFC 2183) describes how the encapsulated NSS is to be processed and how to handle the received Content-Type if it is not recognized. The default disposition-type for a NSS message body is "signal". This type indicates that the body part contains signalling information associated with the session, but does not describe the session. This header is optional for NSS.
+
+## 8.5 NSS MIME media type specification
+
+This media type is defined by the following information:
+
+- Media type name: application;
+- Media subtype name: nss;
+- Required parameters: none;
+- Optional parameters: charset;
+- Encoding scheme: us-ascii;
+- Security considerations: See clause 11.
+
+# 9 Encapsulation in SIP
+
+NSS is encapsulated in SIP by placing it in the message body. The Content-Type must have value "application/nss" and Content-Disposition must have value "signal". For an example of a SIP message using a MIME header to carry a NSS body, see Appendix I.
+
+# 10 Encapsulation in H.323
+
+NSS may be tunnelled within H.323 version 4 (11/2000) messages.
+
+However, in order to be backward compatible, the NSS messages can be tunnelled in the **non-StandardControl** field of the H323-UU-PDU parameter of H.323v2 and H.323v3 messages.
+
+# 11 Security considerations
+
+Security of NSS, if needed, should use the mechanisms defined for securing components of the encapsulating protocol (i.e., SIP or H.323).
+
+# 12 NSS-specific syntactical elements and procedures
+
+## 12.1 NSS-specific messages
+
+All NSS messages, which are also declared in ISUP, will be used as described in the signalling procedures of ITU-T Rec. Q.761/Q.1902.1. Q.1980.1 will cover handling for new messages or changes to those Recommendations.
+
+### 12.1.1 Generic Parameter List (GPL)
+
+The GPL message is used when an application needs to transmit any combination of parameters outside the context of the other defined message types. No semantics are associated with GPL and no state-machine changes are implied.
+
+### 12.1.2 Unrecognized Message (UNR)
+
+UNR extends the concept of handling unrecognized parameters to messages. The UNR message transparently transports any message that is not recognized by the native protocol at ingress. The MCI parameter provides the message handling instruction and carries the content of the unrecognized message that is transported to the final destination that may then dispose of the message accordingly.
+
+## 12.2 NSS-specific parameters
+
+This clause briefly describes the NSS-specific parameters.
+
+### **12.2.1 Unrecognized field handling (UFC: Field compatibility mechanism)**
+
+UFC extends the concept of handling unrecognized parameters using the parameter compatibility information (PCI) to using field compatibility to handle unrecognized fields within a parameter. Further details of parameter construction are defined in clause 12.3 below.
+
+### **12.2.2 Unrecognized value handling (FDC: Value compatibility mechanism)**
+
+FDC extends the PCI and UFC concept to cases where the field is recognized, but the value is not recognized. Further details of parameter construction are defined in 12.3 below.
+
+### **12.2.3 Protocol Name/Version (PRN)**
+
+PRN provides information about the source protocol for the messages and parameters necessary to interpret them. In particular, compatibility parameters require PRN for interpretation.
+
+### **12.2.4 Version (VER)**
+
+VER provides information about the version of NSS used to construct the NSS message and parameters. Use of the same version ensures that parsing of NSS parameters is done correctly.
+
+### **12.2.5 Segmentation Indicator (SEG)**
+
+SEG indicates that an additional SGM message is to follow with additional parameters related to the message carrying the SEG parameter.
+
+### **12.2.6 Global Call Identification (GCI)**
+
+GCI enables all messages associated with a single "call" to be associated.
+
+### **12.2.7 Transaction Identifier (TID)**
+
+At the first ingress point to an IP network, a unique transaction identifier (TID) may be populated on the message. This may be passed unchanged throughout the network so that external call tracing tools (sniffers) can associate any arriving event with its associated generated events.
+
+### **12.2.8 Mapped Parameter List (MPL)**
+
+MPL is used to indicate which parameters from the source protocol have been mapped into the parameters of the encapsulating protocol. However, when a parameter is carried by both the protocol encapsulating NSS and NSS, the parameter name shall not be carried in MPL. The parameter list from MPL and the NSS indicates the parameters that were present in the original source message. This aids the receiving node in reconstructing the original PSTN message, albeit some values may have changed.
+
+NOTE – Movement of a parameter, e.g., through mapping, between NSS and the protocol that carries it, requires a corresponding adjustment to the MPL. The specification of such an interworking, e.g., SIP/NSS to H.323/NSS, is not in the scope of this Recommendation.
+
+### **12.2.9 Source Parameter Information (SPI)**
+
+SPI is used to indicate what source parameter type provided the initial information, when the source protocol defines more than one parameter type that could carry the same information, and when a subsequent PSTN call leg is required to use the identical parameter type. If two instances of a parameter are carried by the source protocol, then the order of SPI parameters indicates the original order of the source parameters.
+
+## **12.3 NSS compatibility procedures**
+
+The PRN parameter in the message is used to interpret any message/parameter/field compatibility information included in the message. Failure to include this information in the message may
+
+preclude any such information from being utilized or understood. This could result in the call being dropped if the compatibility instructions point to this action.
+
+No field shall be placed in a NSS parameter line unless it has been declared in this Recommendation. All fields which exist in network-specific variants of the source protocol, but not in the corresponding parameter for a given NSS parameter specified in this Recommendation, will be treated as unrecognized fields. The parameter name, unrecognized field name, and value can be indicated in a following UFC parameter using field compatibility procedures. Any parameter exceptions to field values can be referenced by parameter name and field number in the FDC parameter.
+
+NOTE – With respect to the UFC parameter, the ordering of optional fields in national variants of ISUP that may be mapped to UFC is not in the scope of this Recommendation.
+
+The compatibility parameters for unknown fields (UFC) and unknown values (FDC) must directly follow the parameter that they modify. If compatibility for more than one field is required, the order from top to bottom of the compatibility parameters follows the order defined in NSS or indicates the field order from the source protocol parameter, if not found in NSS. Modification of compatibility parameters is consistent with modification of other parameters such that only the current instance of a compatibility parameter is present in the message for each parameter, field, or value. Examples of the ordering of compatibility parameters are shown in Appendix I.
+
+A stand-alone FDC or UFC is a syntax error. Handling in that case is not in the scope of this Recommendation.
+
+When encoding an unrecognized syntax element, the lowest (most granular) compatibility mechanism should be used. For example, with unrecognized:
+
+- field values, use Known Field Compatibility Information (FDC)
+- fields, use Unknown Field Compatibility Information (UFC)
+- parameter tags, use Parameter Compatibility Information (PCI)
+- message tags, use Unrecognized Message (UNR).
+
+In essence, UNR should be the last resort, not the first.

+
+To illustrate the use of the 'application/nss' media type, below is an INVITE message which has the originating SDP (specified in RFC 2327) information and the encapsulated ISUP IAM. Note that the two payloads are demarcated by the boundary parameter (specified in RFC 2046) which in the example has the value "unique-boundary". This is part of the specification of MIME multipart and is not related to the 'application/nss' media type.

+### I.2 Compatibility ordering example
+
+The following is an example of the order in which compatibility parameters are found in an NSS message. A FDC (or UFC) must immediately follow the parameter whose field value needs the FDC (or UFC). If there are more than one FDC for the same instance of a parameter, the order of those FDCs (or UFCs) shall follow the order of the fields that occur in the parameter.
+
+For example, suppose both the noa and pi fields of the first GEA need FDC and the si field of the second GEA also need FDC, then proper order of parameters shall be:
+
+```
+
+GEA,<type>,<noa>,<npi>,<cni>,<pi>,<si>,<#>
+FDC for noa,,,
+FDC for pi,,,
+GEA,<type>,<noa>,<npi>,<cni>,<pi>,<si>,<#>
+FDC for si,,,
+
+```
+
+The following is an incorrect message structure, because it would indicate that the values in the three FDC parameters were associated with the number found in the second GEA parameter:
+
+```
+
+GEA,<type>,<noa>,<npi>,<cni>,<pi>,<si>,<#>
+GEA,<type>,<noa>,<npi>,<cni>,<pi>,<si>,<#>
+FDC for noa,,,
+FDC for pi,,,
+FDC for si,,,
+
+```
+
+### I.3 GCI and TID structure example
+
+The following are some suggested guidelines for constructing GCI and TID values.
+
+Use values of the form: locally-unique-identifier@address, where locally-unique-identifier is a value determined by the protocol, and address is a globally unique. Use of an IPv4 address of the form: 123.123.123.123, IPv6 address, or a fully qualified domain name (FQDN) is recommended. An ASCII representation of the 48-bit IEEE 802 address can also be used. It is recommended that the locally-unique-identifier be a 16-character value composed of monotonically increasing IA5 0-9 or A-F characters.
+
+For mapping to the ITU-T H.225 standard for GloballyUniqueID, this could also be a 16-character ASCII representation of a UTC timestamp followed by a 4-character ASCII representation of the clock sequence. That could be expanded directly from the 10-byte 8-bit value from GloballyUniqueID or the UTC timestamp could be ordered with the year in the leftmost position.
+
+The BICC Global Call Reference binary octets could be represented as hex digits in the locally\_unique\_identifier, followed by the "@" and the FQDN of the gateway. The "dot" character would separate the three parts of the global call reference (e.g., a 3-octet reference value:
+
+msb->1000 0010<-lsb, 0000 0011, and 0001 1010 would appear as: 82.03.1A@gw1-abc.com).
+
+Since the Call-ID is generated by and for SIP, there is no reason to deal with the complexity of URL-encoding and case-ignoring string comparison. The following is extracted from SIP:
+
+The callid MUST be a globally unique identifier and MUST NOT be reused for later calls. Use of cryptographically random identifiers is RECOMMENDED. Implementations MAY use the form "localid@host". Call-IDs are case-sensitive and are simply compared byte-by-byte. Using cryptographically random identifiers provides some protection against session hijacking. Call-ID, To and From are needed to identify a call leg. The distinction between call and call leg matters in calls with third-party control.
+
+# Appendix II
+
+## NSS verbose encoding
+
+It is possible to easily generate the verbose description from compact transmission mode by inserting the field name string literals of the form "tag=" into their fixed positions. Likewise, the compact mode can be generated from the verbose description by removing the "tag=" from all fields.
+
+### General format of NSS verbose description ABNF
+
+The compact transmission encoding and verbose description use identical message, parameter, and value formats. Only the field encoding differs. The field formats include the tag literals as defined below.
+
+```
+verbose_message = VER_param CRLF ; using the field definitions below
+    PRN_param CRLF ; using the field definitions below
+    nss_msg_name "," CRLF

+# FOREWORD
+
+The ITU Telecommunication Standardization Sector is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.2100 was prepared by the ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 29th of July 1994.
+
+# --- NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+# 4 General
+
+The ATM adaptation layer (AAL) is defined as enhancing the services provided by the ATM layer to support the functions required by the next higher layer. Different AALs support various protocols to suit the different needs of a range of AAL service users. Recommendation I.362 gives an overview of the basic structure of an AAL and the manner in which it aligns with the service class.
+
+One particular type of AAL service user is the signalling entity wishing to communicate with a peer entity. Any such entity would require that functions are provided above the common part of the AAL specifically designed to facilitate this task.
+
+The information transfer between the SAAL user and the SAAL is performed in Message Mode. Two peer-to-peer operational procedures may be offered: Unassured or Assured operation.
+
+# 5 Description of SAAL
+
+The complete specification of the SAAL is indicated in Figure 1. The SAAL makes use of the service provided by the Common Part Convergence Sublayer (CPCS) and Segmentation and Re-assembly (SAR) which form the common part of AAL type 5. The Service Specific Convergence Sublayer (SSCS) part of AAL type 5 is performed by a combination of the Service Specific Connection Oriented Protocol (SSCOP) and one of several types of Service Specific Coordination Function (SSCF), two of which are currently defined and shown in the figure. The function of the SSCOP is such as to make it equally well suited for use by the user plane. A description of each SAAL component follows.
+
+## 5.1 SAAL-SAP
+
+This is the Service Access Point (SAP) through which all SAAL functions are accessed by the next higher layer. It provides bi-directional flow of information.
+
+Further information regarding this component is found in Recommendations Q.2130 and Q.2140.
+
+## 5.2 SSCF-UNI
+
+This is the Service Specific Coordination Function which maps the particular requirements of the UNI layer 3 protocol to the SSCOP services.
+
+Further information regarding this component is found in Recommendation Q.2130.
+
+## 5.3 SSCF-NNI
+
+This is the Service Specific Coordination Function which maps the particular requirements of the NNI layer 3 protocol to the SSCOP services.
+
+Further information regarding this component is found in Recommendation Q.2140.
+
+## 5.4 SSCOP
+
+This is the Service Specific Connection Oriented Protocol function which provides mechanisms for the establishment and release of connections and the reliable exchange of information between peer entities.
+
+Further information regarding this component is found in Recommendation Q.2110.

+
+## 5.5 CPCS
+
+This is the Common Part Convergence Sublayer which provides transparent transport of Service Data Units produced by the next higher layer.
+
+Further information regarding this component is found in clause 6/I.363.
+
+## 5.6 SAR
+
+This is the Segmentation and Re-assembly function. It provides the services whereby SAR service data units (SDUs) are segmented to fit into outgoing ATM cells, while incoming cells are reassembled into SAR SDUs and data are passed up to the CPCS.
+
+Further information regarding this component is found in clause 6/I.363.
+
+## 5.7 ATM-SAP
+
+This is the point through which all ATM functions are accessed by the ATM adaptation layer. It provides bidirectional flow of information.
+
+Further information regarding this component is found in Recommendation I.361.

+# NOTES
+
+1 ITU-T Recommendation Q.22 was published in Fascicle VI.1 of the *Blue Book*. This file is an extract from the *Blue Book*. While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+# **FREQUENCIES TO BE USED FOR IN-BAND SIGNALLING**
+
+To reduce the risk of signal imitation by speech currents, the frequencies for an in-band signalling system should be chosen from the frequencies in the band in which speech signal power is lowest, i.e. frequencies above 1500 Hz.
+
+The desirability of this was confirmed by tests carried out in London, Paris and Zurich in 1946 and 1948 to choose the signalling frequencies of systems standardized by the CCITT. These tests led to the conclusion that, if relative freedom from false signals was to be obtained other than by undue increase in signal duration, frequencies of at least 2000 Hz would have to be used.

While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).

+
+## Recommendation Q.23
+
+# TECHNICAL FEATURES OF PUSH-BUTTON TELEPHONE SETS
+
+1 The introduction of push-buttons on telephone sets may have an effect on the operation of international circuits:
+
+- a) owing to the greater dialling speed, the post-dialling may be longer, since national and international networks will only be gradually adapted to allow for this greater speed;
+- b) when pressing the buttons after an international call has been set up, the signalling frequencies for push-button sets may cause interference to foreign signalling systems on the connection. However, the subscriber can be warned of the possible disadvantages of touching the buttons in conditions different from those prescribed.
+
+2 There can be no doubt that, owing to the high dialling speed which can be obtained with push-button sets, their use is bound to spread widely and rapidly and it is desirable for the signalling methods for such sets to be internationally standardized.
+
+One factor in favour of such standardization is the advantage it offers for countries which have to import their equipments from various other countries. This argument, admittedly, applies to any type of telephone equipment.
+
+Other advantages of standardization are:
+
+- the possibility of using the push-button of such sets for signalling directly from one subscriber to another subscriber via a national and/or international connection;
+- the standardized allocation of signalling frequencies for push-button sets facilitates the choice of signalling frequencies in the frequency band of a telephone circuit for any other use (data transmission, telephone signalling system, etc.) for which provision might have to be made. The risk of mutual interference among the signalling systems (see Recommendation Q.25) makes it necessary to have an orderly arrangement of the spectrum of frequencies used for signalling.
+
+3 The general use of push-button sets for purposes other than telephone dialling is envisaged by some Administrations. However, some Administrations observe that it would seem advisable to reserve such uses for a network of relatively limited extent; in their view the reliability of standards for data transmission should not make any demands on the push-button set system other than those required for the transmission of telephone numerical information to the local exchange, if the design of push-button sets is to remain within economical limits compatible with their widespread use.
+
+However, the CCITT considered, at Mar del Plata in 1968 that, even if the transmission of data from a push-button telephone set is at present to be envisaged in international traffic on a limited scale only, it would nonetheless be wise not to rule out the possibility of such transmission of data on a general scale.
+
+4 In choosing a signalling system for push-button sets, Administrations may be guided by conditions which vary considerably from one country to another. Economic considerations may, for instance, lead them to prefer a direct current system which might be less expensive than a voice-frequency system. The numerical dialling information would then be transmitted only as far as the telephone exchange to which the subscriber is connected. There are no tones that could affect the connection after its establishment. Data would not be transmitted from the push-button sets unless a suitable converter were used in the exchange.
+
+Standardization of a direct current system for signalling from push-button sets does not seem justified at the international level; it may depend on the conditions peculiar to the local networks of the country concerned.
+
+5 The signalling system for push-button sets recommended by the CCITT applies solely to voice-frequency signals.
+
+A multifrequency code for such signalling is recommended in which the dialling signal is composed of two frequencies emitted simultaneously when a button is pressed. It is planned to have 10 decimal digits and 6 reserve signals, making 16 signals in all. The two frequencies composing each signal are taken from two mutually exclusive frequency groups of four frequencies each, a code known as the "2 (1/4) code".
+
+6 The low group frequencies of this 2 (1/4) code are:
+
+697, 770, 852, 941 Hz.
+
+The high group frequencies are:
+
+1209, 1336, 1477 and 1633 Hz.
+
+The allocation of frequencies to the various digits and symbols of a push-button set appears in Figure 1/Q.23.
+
+7 The frequency variation tolerances and the permissible intermodulation products are defined as follows:
+
+7.1 each transmitted frequency must be within  $\pm 1.8\%$  of the nominal frequency;
+
+7.2 the total distortion products (resulting from harmonics or intermodulation) must be at least 20 dB below the fundamental frequencies.
+
+8 The CCITT determined, at Mar del Plata in 1968, that it was not practicable to specify a standardization of the levels for the frequencies transmitted when a push-button is pressed, as these level conditions depend essentially on national transmission plans which are not the same in all countries.
+
+However, the sending level conditions must be such that on an international connection they do not exceed the values specified in Recommendation Q.16 (maximum permissible value for the absolute power level of a signalling pulse).

+## NOTES
+
+1 ITU-T Recommendation Q.24 was published in Fascicle VI.1 of the *Blue Book*. This file is an extract from the *Blue Book*. While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+# **MULTIFREQUENCY PUSH-BUTTON SIGNAL RECEPTION**
+
+## **1 Introduction**
+
+Characteristics of multifrequency push-button (MFPB) telephone sets using voice frequency signals are included in Recommendation Q.23. This Recommendation Q.24 is intended primarily for application in local exchanges for the reception of MFPB signals. Other MFPB signal receiving applications, such as transit exchanges, would need to take into account the effects of transmission impairments, such as signal clipping, that could be introduced in long distance telephone networks. Since technical factors, such as transmission loss, vary among national networks, varying national standards exist. Varying standards may also exist, for example, to incorporate differences between local and transit exchange applications. This Recommendation is not intended to supersede existing national standards nor is it intended to imply that Administrations should modify those standards.
+
+## **2 Technical parameters**
+
+### **2.1 General**
+
+The technical parameters identified herein are fundamental to the MFPB receiving function and reasons are given for the importance of each parameter. The parameters require operational values to be specified for compatibility with the MFPB sending equipment (Recommendation Q.23) and the network environment in which the receiving equipment must function. Annex A contains a Table showing values for some of these parameters that have been adopted by various Administrations and RPOAs. In addition to the fundamental parameters covered by this Recommendation, Administrations should consider whether other parameters need specification to account for operating conditions found in their networks.
+
+### **2.2 Signal frequencies**
+
+Each signal consists of two frequencies taken from two mutually exclusive frequency groups (a high group and a low group) of four frequencies each, as specified in Recommendation Q.23. These frequencies and their allocation to form the various digits and symbols of the push-button signalling code are defined in Recommendation Q.23. The exchange shall provide a check for the simultaneous presence of one and only one frequency from the high group and one and only one from the low group.
+
+### **2.3 Frequency tolerances**
+
+The exchange should respond to signals whose frequencies are within the tolerances for MFPB sending. Somewhat wider tolerances may be appropriate, for example to cater for transmission impairments encountered in subscriber cables or FDM transmission facilities. However, wider limits may increase susceptibility to noise and digit simulation by speech.
+
+### **2.4 Power levels**
+
+The exchange should provide proper reception of signals whose power levels are determined by the amplitude of the sending equipment and loss that may be introduced by the subscriber cables or other network elements. The sending amplitude and transmission attenuation may be different for different frequencies. The reception characteristics may take advantage of a limitation, if specified, on the maximum difference in power level between the two received frequencies forming a valid signal to facilitate improved overall performance.
+
+### **2.5 Signal reception timing**
+
+The exchange should recognize signals whose duration exceeds the minimum expected value from subscribers. To guard against false signal indications the exchange should not respond to signals whose duration is less than a specified maximum value. Similarly, pause intervals greater than a specified minimum value should be recognized by the exchange. To minimize erroneous double-registration of a signal if reception is interrupted by a short break in transmission or by a noise pulse, interruptions shorter than a specified maximum value must not be recognized. The
+
+maximum rate at which signals can be received (signalling velocity) may be related to the above minimum values. All of these values may also be determined by subscriber feature requirements.
+
+### 2.6 *Signal simulation by speech*
+
+Because telephone set speech transmitters are normally connected in the circuit during the push-button dialling interval, it is necessary for the exchange to properly receive valid MFPB signals in the presence of voice or other disturbances. The nature of such disturbances may vary from one geographical area to another. The number of calls affected by signal simulation should not significantly degrade the overall telephone network performance experienced by subscribers.
+
+Since actual immunity to digit simulation may be difficult to measure, a test environment using recorded speech, music, and other voice frequency sounds may be utilized to verify design performance.
+
+### 2.7 *Interference by dial tone*
+
+MFPB reception should not be adversely affected while dial tone is being applied. Characteristics of dial tone such as frequencies, power levels and spurious components are covered in Recommendation Q.35. These characteristics are specified to minimize the interference between the dial tone sending and the MFPB receiving functions. These functions are normally provided by closely related exchange equipment which must be designed to function properly over the entire range of signal characteristics and transmission impairments to be encountered.
+
+### 2.8 *Interference by echos*
+
+MFPB signal reception from extended subscriber lines having long 4-wire transmission sections must discriminate between a true signal condition and an echo condition which may persist for a number of milliseconds. Failure to provide such discrimination could result in signal reception errors, for example due to a reduction of the detected pause duration. Administrations having such extended subscriber lines with MFPB signalling should therefore specify the echo conditions under which the MFPB signalling function must operate.
+
+### 2.9 *Noise immunity*
+
+Noise sources such as power lines, electric railways and telecommunication circuits may induce electrical disturbances with various characteristics into MFPB signalling paths. These disturbances may cause MFPB signals to be missed, split (double signal registration) or cause signal simulation. The distortion products produced by the MFPB signalling source should also be included in the noise environment. A realistic noise environment specification and facilities for testing MFPB reception under the specified conditions, e.g., using recorded test tapes, are important to ensure that performance standards will be met under actual service conditions.

+## **ITU-T Recommendation Q.2630.3**
+
+# **AAL type 2 signalling protocol – Capability Set 3**
+
+# **Summary**
+
+This Recommendation specifies the inter-node protocol and nodal functions that control AAL type 2 point-to-point connections.
+
+The AAL type 2 signalling protocol specified in this Recommendation is usable in switched and non-switched environments and can operate in public or private networks over a range of signalling transport protocol stacks.
+
+It also provides maintenance capabilities, carriage of user-plane protocol stack information and carriage of an identifier to link the connection control protocol with other higher layer control protocols.
+
+## **Source**
+
+ITU-T Recommendation Q.2630.3 was approved on 14 October 2003 by ITU-T Study Group 11 (2001-2004) under the ITU-T Recommendation A.8 procedure.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# **AAL type 2 signalling protocol – Capability Set 3**
+
+# **1 Scope**
+
+This Recommendation describes the AAL type 2 signalling protocol that supports the dynamic establishment and release of individual AAL type 2 point-to-point connections. It also describes the maintenance procedures, the framework of the protocol, and the interactions between an AAL type 2 signalling protocol entity and:
+
+- the signalling protocol user;
+- a signalling transport converter; and
+- layer management.
+
+This Recommendation also describes the connection states, messages, parameters, timers, local, and peer-to-peer procedures used for the control of those connections. The scope of this Recommendation is illustrated in Figure 1-1. The AAL type 2 signalling protocol can be deployed over a range of signalling transport protocol stacks.
+
+This Recommendation is based on the requirements defined in ITU-T Q-series Recommendations – Supplement 42 [21] "Signalling Requirements for AAL type 2 Link Control Capability Set 3".
+
+![Functional architecture of the AAL type 2 signalling diagram showing two symmetric stacks. Each stack consists of an AAL type 2 served user (top), an AAL type 2 signalling entity, a Signalling transport converter, and a Signalling transport entity (bottom). The AAL type 2 signalling entity is connected to the user via SAPs and primitives, to the converter via generic primitives, and to layer management via SAPs and primitives.

+
+Detailed Diagram Description: The diagram illustrates the functional architecture of AAL type 2 signalling. It features two identical vertical stacks representing peer entities. Each stack, from top to bottom, includes: 'AAL type 2 served user' (Note 2), 'AAL type 2 signalling', 'Signalling transport converter', and 'Signalling transport'. These layers interact through Service Access Points (SAPs) and Primitives. Specifically, 'AAL type 2 signalling' interacts with the 'AAL type 2 served user' via SAPs and Primitives, and with the 'Signalling transport converter' via 'Generic primitives'. The 'Signalling transport converter' interacts with 'Signalling transport' via 'Specific primitives' and SAPs. On the far left and right, 'Layer management' blocks interact with the 'AAL type 2 signalling' layer via SAPs and Primitives. A large gray dashed box labeled 'This Recommendation (Note 1)' encloses the 'AAL type 2 signalling' blocks and their immediate SAP interfaces. A horizontal dashed line labeled 'AAL type 2 signalling messages' connects the two 'AAL type 2 signalling' blocks. At the bottom, a dashed line connects the two 'Signalling transport' blocks, indicating the physical or lower-layer connection.

+
+In addition, for the purposes of this Recommendation, the following definitions apply:
+
+**3.1 AAL type 2 channel:** A concept used in ITU-T Rec. I.363.2 [1] to describe transport of CPS-packets [1] associated in a common unique identifier value called CID on an ATM VCC.
+

+
+# 5 General framework of the AAL type 2 signalling protocol
+
+The AAL type 2 signalling protocol provides the signalling capability to establish, release and maintain AAL type 2 point-to-point connections across a series of ATM VCCs that carry AAL type 2 links. These services are accessible via the AAL type 2 served user service access point (A2SU-SAP).
+
+The AAL type 2 signalling protocol also provides maintenance functions associated with the AAL type 2 signalling.
+
+An AAL type 2 signalling endpoint shall be able to control AAL type 2 links on more than one AAL type 2 path. These AAL type 2 paths may be contained on different ATM VPCs, which in turn may be carried on different ATM physical interfaces.
+
+Two peer AAL type 2 signalling entities rely on the generic signalling transport service to provide assured data transfer between them and service availability indications. These services are accessible via the Generic Signalling Transport Service Access Point (GST-SAP).
+
+NOTE – Primitives over the A2SU-SAP, GST-SAP, and LM-SAP are used for descriptive purpose only. They do not imply a specific implementation.
+
+Both peer AAL type 2 signalling entities provide the same set of services.
+
+The AAL type 2 signalling entity is subdivided into protocol entities and nodal functions as shown in Figure 5-1. At each AAL type 2 service endpoint, the AAL type 2 signalling entity communicates with the AAL type 2 served user. At an AAL type 2 switch, the AAL type 2 signalling entity does not communicate with an AAL type 2 served user.
+
+![Figure 5-1/Q.2630.3 – AAL type 2 signalling protocol reference architecture. This diagram shows the protocol stack for AAL type 2 signalling across three nodes: an AAL type 2 service endpoint, an AAL type 2 switch, and another AAL type 2 service endpoint. Each node contains an 'AAL type 2 served user' connected to an 'AAL type 2 signalling entity' via an A2SU-SAP. The signalling entity consists of a 'Nodal function' and a 'Protocol entity'. The Nodal function is connected to a 'Layer management' block via an LM-SAP. The Protocol entity exchanges 'AAL type 2 Signalling message' with the adjacent node's Protocol entity. Below the signalling entity is a 'Signalling transport converter' connected via a GST-SAP. This converter is connected to a 'Signalling transport' layer (e.g., MTP3b + NNI-SAAL, UNI-SAAL, SSCOP, ...). Notes indicate that in every AAL type 2 node, a signalling transport converter instance is associated with each AAL type 2 signalling transport. The diagram is labeled Q.2630.3_F5-1 at the bottom right.](fa859e4e468bfb2710a94527f2c504af_img.jpg)

+NOTE – In every AAL type 2 node, a signalling transport converter instance is associated with each AAL type 2 signalling transport.
+
+**Figure 5-1/Q.2630.3 – AAL type 2 signalling protocol reference architecture**
+
+Protocol Entities define the interactions between two adjacent AAL type 2 nodes. AAL type 2 messages are exchanged between peer protocol entities using the generic signalling transport service.
+
+The AAL type 2 signalling is independent of the signalling transport, although an assured data transport is required and a message size limit applies. The Generic Signalling Transport Service used is defined in ITU-T Rec. Q.2150.0 [12]. To adapt the Generic Signalling Transport Services to a specific signalling transport service, a signalling transport converter may be needed. The specification of signalling transport converters is beyond the scope of this Recommendation (see ITU-T Recs Q.2150.1 [22], Q.2150.2 [23] and Q.2150.3 [28]).
+
+The protocol entity is divided into several procedures as shown in Figure 5-2.
+
+![Figure 5-2/Q.2630.3 – Internal structure of the AAL type 2 signalling protocol entity. This diagram shows the internal structure of a 'Protocol entity' box. It contains three sub-boxes: 'Outgoing protocol procedures', 'Incoming protocol procedures', and 'Maintenance protocol procedures'.

+
+The outgoing protocol procedures provide the mechanism to initiate an AAL type 2 connection request. The incoming protocol procedures are applied when a request for an AAL type 2 connection is received from a peer entity. Both of these procedures provide for the orderly release of an AAL type 2 connection. The maintenance protocol procedures provide the mechanisms to align the status of the AAL type 2 resources at the two adjacent AAL type 2 nodes and the procedures to block and unblock an AAL type 2 path.
+
+The unrecognised information procedures in the nodal function as well as in the protocol entities provide the forward compatibility mechanism which enables extension of the protocol in the future.
+
+The nodal function provides the bridge between incoming and outgoing protocol entities, performs the routing functionality, and keeps track of the AAL type 2 path resources.
+
+## **5.1 Interface between the AAL type 2 signalling entity and the AAL type 2 served user**
+
+### **5.1.1 Service provided by the AAL type 2 signalling entity**
+
+The AAL type 2 signalling entity provides the following services to the AAL type 2 served user across the A2SU-SAP:
+
+- establishment of AAL type 2 connections;
+- release of AAL type 2 connections; and
+- modification of AAL type 2 connection resources.
+
+The AAL type 2 signalling protocol entity is independent of the AAL type 2 served user.
+
+### **5.1.2 Primitives between AAL type 2 signalling entities and the AAL type 2 served user**
+
+The A2SU-SAP primitives are used:
+
+- 1) by the originating served user to initiate AAL type 2 connection establishment and by the originating and destination served users to initiate the release of a connection;
+- 2) by the AAL type 2 signalling entities to indicate an incoming connection to the destination served user and notifying either the originating or destination served user of the release of a connection;
+- 3) by the modification sending served user to originate, and the modification receiving served user to respond to, an AAL type 2 connection resource modification request; and
+- 4) by the AAL type 2 signalling entities to indicate a modification of the AAL type 2 connection resource to the modification receiving served user and notify the modification originating served user of the successful or unsuccessful modification.
+
+NOTE – When sending a primitive between the signalling protocol and its user, the primitive needs to be associated with a particular AAL type 2 connection instance. The mechanism used for this binding is considered to be an implementation detail and therefore is outside the scope of this Recommendation.
+
+The services are provided through the transfer of primitives which are summarized in Table 5-1, and are defined after the table.
+
+The AAL type 2 served user passes information in parameters in the primitives. Some of those parameters are mandatory and some are optional; the appropriate usage of the parameters is described in clause 8.

+- i) **Preferred Link Characteristics (PLC)**  
+This parameter gives an indication that the Link Characteristics shall be set as indicated in this parameter if the modification of the Link Characteristics is permitted.
+
+#### j) **Modify Support for Link Characteristics (MSLC)**
+
+This parameter gives an indication that the AAL type 2 Link Characteristics of the AAL type 2 connection may need to be modified during the lifetime of the AAL type 2 connection (ESTABLISH.request) or is permitted to be modified (ESTABLISH.indication and ESTABLISH.confirm).
+
+#### k) **SSCS Information (SSCS)**
+
+This parameter identifies the type and the capabilities of an AAL type 2 SSCS protocol. This parameter can have the form of either:
+
+- Service Specific Information (Multirate) (see ITU-T Rec. I.366.2 [14]),
+- Service Specific Information (Audio) (see ITU-T Rec. I.366.2 [14]),

+
+NOTE – Multirate Extended and Audio Extended are used in this Recommendation to support the services of the U-Plane definitions of the 2000 version of ITU-T Rec. I.366.2 [14]. The (non-extended) Multirate and Audio are retained for backward compatibility with ITU-T Rec. Q.2630.1 [15]. For example, the Audio Extended form of the SSCS Information parameter in this Recommendation (see 7.4.19) adds support for LB, RC, and SYN that were added as U-Plane functions in the 2000 version of ITU-T Rec. I.366.2 [14].

+
+Modification of Frame Mode Data as specified in ITU-T Rec. I.366.2 [14], or modification of SAR as specified in ITU-T Rec. I.366.1 [9] is outside the scope of this Recommendation.

+#### p) **Test Connection Indication (TCI)**
+
+By its presence, this parameter indicates that the AAL type 2 connection to be established is a test connection.
+
+#### q) **Cause**
+
+This parameter describes the reason for the release of the AAL type 2 connection. It also may indicate the reason why an AAL type 2 connection could not be established or a modification was rejected.

+
+This parameter carries the SSCS correlation ID (as specified in ITU-T Rec. I.366.2 [14]) during the modification of SSCS information and is transported unmodified to the destination or origination served user.
+
+## 5.2 Interface between the AAL type 2 signalling entity and the generic signalling transport
+
+### 5.2.1 Service provided by the generic signalling transport service
+
+The Generic Signalling Transport Service is specified in ITU-T Rec. Q.2150.0 [12]. For convenience, a summary of the primitives for accessing the service is reproduced in Table 5-2. In the event of any difference between this table and the definitions in ITU-T Rec. Q.2150.0, the definitions in ITU-T Rec. Q. 2150.0 take precedence.
+

+
+NOTE 1 – This primitive has no parameters.  
+NOTE 2 – This parameter is a national option (and the use of this parameter is not supported by all signalling transports).
+
+On the establishment of a signalling transport converter entity and the respective signalling transport converter user entity, for example at power up, the initial conditions are the same as if an OUT-OF-SERVICE.indication primitive had been conveyed across this SAP. Also at this time the START-INFO.indication is sent to the signalling entity.
+
+NOTE – The CIC\_Control parameter of the START-INFO.indication is ignored by the AAL type 2 signalling entity.

+### 5.2.2 State transition diagram for sequences of primitives of the generic signalling transport service
+
+This clause defines the constraints on the sequences in which the primitives may occur at the layer boundaries of the generic signalling transport service. The sequences are related to the states at one generic signalling transport endpoint between the generic signalling transport service provider and its user. The possible overall sequences of primitives are shown in the state transition diagram, Figure 5-3.

+NOTE – When sending a primitive between the AAL type 2 signalling entity and layer management, the primitive needs to be associated with a particular management action instance. The mechanism used for this binding is considered to be an implementation detail and, therefore, is outside the scope of this Recommendation.

+
+# 6 Forward and backward compatibility
+
+The compatibility mechanism remains unchanged for all capability sets and/or subsets of the AAL type 2 protocol defined in this Recommendation. It is based on forward compatibility information associated with all signalling information.
+
+The compatibility method eases the network operation, for example:
+
+- For the typical case of an AAL type 2 signalling protocol mismatch during a network upgrading.
+- To interconnect two networks on a different functional level.
+- For networks using a different subset of the same AAL type 2 protocol, etc.
+
+NOTE – A node may be at a different functional level due to having implemented a different capability set or another subset of the protocol specified in this Recommendation.
+
+The coding of message and parameter compatibility information is shown in Annex B; these codings shall be used to maintain backward compatibility with AAL type 2 nodes conforming only to ITU-T Rec. Q.2630.1 [15] and with AAL type 2 nodes conforming only to ITU-T Rec. Q.2630.2 [16].
+
+The forward compatibility mechanism specified in 6.2 and 8.1 applies to this and future capability sets of this Recommendation.
+
+## 6.1 Backward compatibility rules
+
+Compatible interworking between AAL type 2 protocol capability sets should be optimized by adhering to the following rules when specifying a new capability set (release):
+
+- 1) Existing protocol elements, i.e., procedures, messages, parameters and subfield values, should not be changed unless a protocol error needs to be corrected or it becomes necessary to change the operation of the service that is being supported by the protocol.
+- 2) The semantics of a message, a parameter, or of a field and subfield within a parameter should not be changed.
+- 3) Established rules for formatting and encoding messages and parameters should not be modified.
+
+## 6.2 Forward compatibility mechanism
+
+Compatibility between this and future capability sets will be guaranteed, in the sense that any two capability sets can be interconnected directly with each other, if the following requirements are fulfilled:
+
+- i) *Protocol compatibility*  
+Connections between any two AAL type 2 protocols do not fail for the reason of not satisfying protocol requirements.
+
+### ii) *Service and functional compatibility*
+
+This feature may be considered as compatibility typically between originating and destination nodes. Services and functions available at these nodes, but possibly not yet taken into account in the intermediate nodes, are supported, provided that information related to these services and functions can be passed transparently through intermediate nodes.
+
+### iii) *Resource control and management compatibility*
+
+For these functions, occurring only link-by-link, at least a backward notification is needed, if correct handling is not possible.
+
+# 7 Format and coding of AAL type 2 signalling protocol
+
+## 7.1 Coding conventions for the AAL type 2 signalling protocol
+
+### 7.1.1 Principles
+
+The following principles shall apply for the coding of the AAL type 2 signalling protocol:
+
+- a) The order of coding of messages shall consist of "destination signalling association identifier", "message identifier", "message compatibility", and any parameters.
+- b) Messages shall carry zero or more parameters.
+- c) The sequence of parameters is unconstrained.
+- d) The order of coding of parameters shall consist of "parameter identifier", "parameter compatibility", "parameter length", and any fields.
+- e) Parameters shall carry zero or more fields.
+- f) A parameter shall always consist of the same sequence of fields.
+- g) If new fields need to be added to a parameter or the length of a fixed size field needs to be changed, the modifications shall be carried in a new parameter (different parameter identifier); the existing parameter shall remain unchanged.
+- h) Any sequence of fixed size fields and variable size fields is permissible.
+- i) Fixed length fields shall consist of the "field" only; no length is indicated.
+- j) Variable length fields shall consist of "field length" and "field".
+- k) Fields shall be multiples of one octet.
+- l) Fields are composed of one or more subfields.
+- m) Reserved subfields shall be coded all zeroes and need not be interpreted by the receiver.
+- n) If there is no information to be carried in a variable size field, its length shall be set to zero, i.e., only the field length octet will be present.
+- o) If there is no information to be carried in a fixed size field, its content shall be set to zero in all octets.
+- p) The presence or the interpretation of a field shall not depend on the value of a field in another parameter.
+
+Consistent with the above coding principles, it is further specified that:
+
+- The message length shall allow for lengths of up to 4 000 octets.
+- The parameter length shall allow for lengths of up to 255 octets.
+
+### 7.1.2 General format of messages
+
+The general format of a message is shown in Table 7-1.
+
+NOTE – No "message length" needs to be carried in the message itself; the length of information passed via a primitive implicitly defines its length and the assured data transfer assures that no octets are lost or gained in transport.
+
+**Table 7-1/Q.2630.3 – AAL type 2 message format**
+
+|         | 8                                             | 7 | 6 | 5 | 4 | 3 | 2 | 1 |          |
+|---------|-----------------------------------------------|---|---|---|---|---|---|---|----------|
+| Header  | Destination signalling association identifier |   |   |   |   |   |   |   | 4 octets |
+|         | Message identifier                            |   |   |   |   |   |   |   | 1 octet  |
+|         | Message compatibility                         |   |   |   |   |   |   |   | 1 octet  |
+| Payload | Parameters                                    |   |   |   |   |   |   |   |          |
+
+The message header consists of the destination signalling association identifier field, the message identifier field, and the message compatibility field. The destination signalling association identifier field is coded the same as the signalling association identifier field (see 7.4.2), the coding of the message identifier field is specified in 7.2.1, and the message compatibility field is coded the same as the compatibility field (see 7.4.1).
+
+The message payload consists of zero, one, or more parameters.
+
+#### 7.1.2.1 Bit coding rules
+
+When a field is contained within a single octet, the lowest bit number of the field represents the lowest order value.
+
+When a field spans more than one octet, the order of bit values within each octet progressively decreases as the octet number increases; the lowest bit number associated with the field represents the lowest order value.
+
+(This coding conforms to the coding conventions specified in 2.1/I.361 [2].)
+
+### 7.1.3 General format of parameters
+
+The general format of a parameter is shown in Table 7-2.
+
+**Table 7-2/Q.2630.3 – AAL type 2 parameter format**
+
+|         | 8                       | 7 | 6 | 5 | 4 | 3 | 2 | 1 |         |
+|---------|-------------------------|---|---|---|---|---|---|---|---------|
+| Header  | Parameter identifier    |   |   |   |   |   |   |   | 1 octet |
+|         | Parameter compatibility |   |   |   |   |   |   |   | 1 octet |
+|         | Parameter length        |   |   |   |   |   |   |   | 1 octet |
+| Payload | Fields                  |   |   |   |   |   |   |   |         |
+
+The coding of the parameter identifier field is specified in 7.2.2, Table 7-7 and the parameter compatibility field is coded as a compatibility field (see 7.4.1). The coding of the parameter length is a binary value indicating the number of octets in the parameter payload, i.e., the count does not include the octets in the parameter header.
+
+Each parameter has a defined number of fields of defined type and in a particular order.
+
+### 7.1.4 General format of fixed length fields
+
+The general format of a fixed length field is shown in Table 7-3.
+
+**Table 7-3/Q.2630.3 – AAL type 2 field – Fixed length format**
+
+![](2ae3eae1bd80a90f192f568ae246a9a6_img.jpg)

+|---------|-------|---|---|---|---|---|---|---|----------|
+|         | 8     | 7 | 6 | 5 | 4 | 3 | 2 | 1 |          |
+| Payload | Field |   |   |   |   |   |   |   | n octets |
+
+The field type is determined by the location of the field in the particular parameter.
+
+### 7.1.5 General format of variable length fields
+
+The general format of a variable length field is shown in Table 7-4.
+
+**Table 7-4/Q.2630.3 – AAL type 2 field – Variable length format**
+
+![](356eb99ab9489bbd647223390a913903_img.jpg)

+|         | 8            | 7 | 6 | 5 | 4 | 3 | 2 | 1 |          |
+|         | Field length |   |   |   |   |   |   |   | 1 octet  |
+| Payload | Field        |   |   |   |   |   |   |   | n octets |
+
+The coding of the field length is a binary value indicating the number of octets in the field payload, i.e., the count does not include the field length octet.
+
+The field type is determined by the location of the field in the particular parameter.

+|                            |   |   |   |   |   |   |   | Octet 4 |
+
+The coding is implementation dependent. It identifies unambiguously an AAL type 2 path between a pair of adjacent AAL type 2 nodes. A value of "0" in all octets indicates "Null"; therefore, the all zero code cannot be used to identify an AAL type 2 path.
+
+NOTE – When the AAL type 2 path is a switched VCC between two adjacent AAL type 2 nodes, the procedure defined in 9.2/Q.2941.2 [27] may be used to assign the AAL type 2 path identifier field value at the time of the VCC establishment.

+# 8 Procedure of the AAL type 2 signalling protocol
+
+Before an ATM VCC (AAL type 2 path) is put into service between a pair of adjacent AAL type 2 nodes, certain actions need to be performed. An identifier called the AAL type 2 path identifier is assigned to the ATM VCC. This identifier is used to refer to the ATM VCC in the AAL type 2 signalling protocol messages. The AAL type 2 path identifier shall uniquely identify the ATM VCC between the two adjacent AAL type 2 nodes.
+
+On any ATM VCC used for AAL type 2 connections, all CID values from "8" to "255" are available for assignment.
+
+Any time a new ATM VCC is put into service, the ownership of the ATM VCC shall be determined before AAL type 2 connections are established in it. In case of switched ATM VCC, the owner of the VCC shall be the AAL type 2 node that initiated the establishment of the VCC. In case of PVC and soft PVC, it is the responsibility of the management system to determine the owner of the VCC.
+
+The nodal function is informed by layer management of a newly established AAL type 2 path by the use of the ADD-PATH.indication primitive containing the adjacent AAL type 2 node identifier, the AAL type 2 path identifier, and the ownership. The nodal function is informed by layer management of the removal of an AAL type 2 path by use of the REMOVE-PATH.indication primitive containing the adjacent AAL type 2 node identifier and the AAL type 2 path identifier.
+
+In order to minimize the likelihood of CID collision, the following CID allocation mechanism shall be used:
+
+- if the AAL type 2 node owns the AAL type 2 path that carries the new connection, it allocates CID values from CID value 8 upwards; and
+- if the AAL type 2 node does not own the AAL type 2 path that carries the new connection, it allocates CID values from CID value 255 downwards.
+
+Each AAL type 2 connection request (regardless of coming directly from an AAL type 2 served user or from an adjacent AAL type 2 node) shall contain an AAL type 2 service endpoint address which indicates the destination of the intended AAL type 2 connection instance. This information is used to route the AAL type 2 connection via the AAL type 2 network to its destination service endpoint. In capability set 3, the supported address formats are: NSAP and E.164.
+
+It is up to the application area or the operator of a particular network to decide what addressing plan is used in the AAL type 2 network. The addressing plan in the AAL type 2 network can be a reuse of the addressing plan in the underlying ATM network but it can also be an independent addressing plan defined exclusively for the AAL type 2 network.
+
+NOTE – Causes in the procedures defined in clause 8 specify which ITU-T standardized code should be used in cause parameters of AAL type 2 signalling protocol messages. Implementation dependent non-standardized causes may be used for AAL type 2 signalling entity internal processing and for A2SU-SAP and LM-SAP cause primitive parameters.
+
+The following procedures may be supported as a network option:
+
+- a) Connection priority;
+- b) Automatic congestion control (see ITU-T Rec. Q.542 [18]);
+- c) Hop Counter Procedure;
+- d) Temporary Alternative Routing Procedure (see ITU-T Rec. E.412 [17]).
+
+## 8.1 Compatibility
+
+### 8.1.1 General requirements on receipt of unrecognized signalling information
+
+It may happen that a node receives unrecognized signalling information, i.e., messages, parameter types or subfield values. This can typically be caused by the upgrading of the signalling system used by other nodes in the network. In these cases, the following compatibility procedures are invoked to ensure the predictable network behaviour.
+
+All messages and parameters shall include a compatibility field generated by the nodal function.
+
+The procedures to be used on receipt of unrecognized information make use of:
+
+- compatibility field received in the same message as the unrecognized information;
+- the cause parameter containing a cause value and diagnostics;
+- the confusion message and the release request message (maintaining the link associated signalling relationship); and
+- the release confirm message, the reset confirm message, the block confirm message, and the unblock confirm message (terminating the link associated signalling relationship).
+
+The following causes are used:
+
+- "message type non-existent or not implemented";
+- "information element/parameter non-existent or not implemented"; or
+- "message with unrecognized parameter discarded".
+
+For all the above causes a diagnostic field is included containing, dependant on the cause, the message identifier and zero, one, or more pairs of parameter identifier and field number.
+
+The procedures are based on the following assumptions:
+
+- i) Since nodes can be both national and international nodes, the compatibility mechanism is applicable to the national and international network.
+- ii) If a node receives a confusion message, a release request message, a release confirm message, a reset confirm message, a block confirm message, or an unblock confirm message indicating an unrecognized message or parameter received, it assumes interaction with a node supporting a different functional level.
+
+NOTE 1 – A node may be at a different functional level due to having implemented a different capability set or another subset of the protocol specified in this Recommendation.
+
+When an unrecognized parameter or message is received, the node will find some corresponding instructions contained in the parameter compatibility information or message compatibility field respectively. The message compatibility field contains the instructions specific for the handling of the complete message.
+
+The instruction indicators consist of two subfields, one to indicate how to handle unrecognized parameters or messages and the other to indicate what to do when an unrecognized parameter or message cannot be passed on. The following general rules apply to the interpretation of these instruction indicators:
+
+- a) "Reserved" subfields of the compatibility field are not examined. They may be used by future capability sets of this Recommendation; in this case, the future capability sets will set the currently defined instruction indicators to a reasonable value for nodes implementing the current capability set. This rule ensures that more types of instructions can be defined in the future without creating a backward compatibility problem.
+- b) At an AAL type 2 node, the connection is released, using normal release procedures, if the instruction indicator is set to "release connection".
+- c) At an AAL type 2 node if the instruction indicator is set to: "Discard message", or "Discard parameter", the message or parameter is discarded, as instructed. If the send notification indicator is set to "send notification", the appropriate message is issued towards the node that sent the unrecognized information:
+  - A confusion message is sent in response to an establish request message, an establish confirm message or in response to an unrecognized message.
+  - The appropriate confirm message is sent in response to a release request message, block request message, unblock request message, or reset request message.
+  - No response is returned in response to a confusion message, release confirm message, block confirm message, unblock confirm message, or reset confirm message.
+- d) At an AAL type 2 node, if the instruction indicator is set to "pass-on", the unrecognized message or parameter is passed to the link associated signalling relationship on the other side of the AAL type 2 switch used for this connection. If the ability to "pass-on" is not possible at an AAL type 2 switch, then the instruction indicators "pass-on not possible" are examined.
+
+NOTE 2 – Examples of where "pass-on" might not be possible are: At AAL type 2 service endpoints, or in AAL type 2 switches in inter-operator situations, where "pass-on" might depend on bilateral agreements.
+- e) For the case of an unrecognized parameter, it is possible for the instruction to require that either the unrecognized parameter or the whole message be discarded. This provides for the case where the sending node determines that it is not acceptable for the message to continue being processed without this parameter.
+
+### 8.1.2 Procedures for the handling of the unrecognized messages or parameters
+
+If the unrecognized signalling information is received, an ERROR.indication primitive with an appropriate cause (described in the following subclauses) is sent to layer management, except when the action taken is to pass on the message or parameter transparently.
+
+A confusion message must not be issued in response to the following messages:
+
+- |                   |                   |                   |
+|-------------------|-------------------|-------------------|
+| • Confusion       | • Block request   | • Block confirm   |
+| • Release request | • Unblock request | • Unblock confirm |
+| • Release confirm | • Reset request   | • Reset confirm   |
+
+Any unrecognized parameters received in the following messages are discarded:
+
+- |                   |                 |                   |
+|-------------------|-----------------|-------------------|
+| • Confusion       | • Block confirm | • Unblock confirm |
+| • Release confirm | • Reset confirm |                   |
+
+#### 8.1.2.1 Unrecognized messages
+
+Depending on the instructions received in the message compatibility field, a node receiving an unrecognized message will either:
+
+- a) transfer the message transparently;
+- b) discard the message;
+- c) discard the message and send notification; or
+- d) release the connection.
+
+The release request in case d) and the confusion message in case c) shall include the cause "Message type non-existent or not implemented", followed by a diagnostic field containing only the message identifier.
+
+#### 8.1.2.2 Unrecognized parameters
+
+Unexpected parameters (a parameter in the "wrong" message) are handled like unrecognized parameters.
+
+Depending on the instructions received in the parameter compatibility information field, a node receiving an unrecognized parameter will either:
+
+- a) transfer the parameter transparently;
+- b) discard the parameter;
+- c) discard the parameter and send notification;
+- d) discard the message;
+- e) discard the message and send notification; or
+- f) release the connection.
+
+In case c), the confusion message shall include the cause "Information element/parameter non-existent or not implemented" followed by a diagnostic field containing the message identifier and containing pairs of parameter identifier and field number for each unrecognized parameter; the field number in each pair is set to "zero".
+
+In case e), the confusion message shall include the cause "Message with unrecognized parameter discarded", followed by a diagnostic field containing the message identifier and a parameter identifier (of the first detected unrecognized parameter which caused the message to be discarded) and a field number set to "zero". A confusion message may refer to multiple unrecognized parameters.
+
+A node receiving a message including multiple unrecognized parameters shall process the different instruction indicators, associated with those parameters, according to the following order:
+
+- 1) release the connection;
+- 2) discard the message and send notification;
+- 3) discard the message.
+
+A release request message shall include the cause "Information element/parameter non-existent or not implemented" followed by a diagnostic field containing the message identifier, the parameter identifier (of the first detected unrecognized parameter which caused the connection to be released), and a field number set to "zero".
+
+If a release request message is received containing an unrecognized parameter, depending on the instructions received in the parameter compatibility field, the node will either:
+
+- transfer the parameter transparently;
+- discard the parameter; or
+
+- discard the parameter and send a cause "Information element/parameter non-existent or not implemented", in the release confirm message; the diagnostic field contains the message identifier and one or more pairs of parameter identifier and field number indicating all parameters that match the cause value; the field number of all pairs contains the null value.
+
+If a block request message is received containing an unrecognized parameter, depending on the instructions received in the parameter compatibility field, the node will either:
+
+- discard the parameter; or
+- discard the parameter and send a cause "Information element/parameter non-existent or not implemented", in the block confirm message; the diagnostic field contains the message identifier and one or more pairs of parameter identifier and field number indicating all parameters that match the cause value; the field number of all pairs contains the null value.
+
+If an unblock request message is received containing an unrecognized parameter, depending on the instructions received in the parameter compatibility field, the node will either:
+
+- discard the parameter; or
+- discard the parameter and send a cause "Information element/parameter non-existent or not implemented", in the unblock confirm message; the diagnostic field contains the message identifier and one or more pairs of parameter identifier and field number indicating all parameters that match the cause value; the field number of all pairs contains the null value.
+
+If a reset request message is received containing an unrecognized parameter, depending on the instructions received in the parameter compatibility field, the node will either:
+
+- discard the parameter; or
+- discard the parameter and send a cause "Information element/parameter non-existent or not implemented", in the reset confirm message; the diagnostic field contains the message identifier and one or more pairs of parameter identifier and field number indicating all parameters that match the cause value; the field number of all pairs contains the null value.
+
+#### 8.1.2.3 Unrecognized fields
+
+There exists no specific compatibility information for each field. For all fields contained in a parameter, the compatibility information of the parameter applies.
+
+Any value in a subfield that is marked as "spare", "reserved" or "national use" is regarded as unrecognized and the procedures as stated for unrecognized parameters apply except that the field number is coded in the diagnostics field.
+
+### 8.1.3 Procedures for the handling of responses indicating unrecognized information has been sent
+
+Action taken on receipt of responses indicating unrecognized information has been sent at an originating or terminating AAL type 2 node will depend on the connection state and the affected service.
+
+The definition of any procedure that is outside the basic connection setup protocol, as defined in this Recommendation, should include procedures for handling responses that indicate that another node has received, but not recognized, information belonging to that procedure. The procedure receiving this response should take the appropriate actions.
+
+The default action taken on receipt of a confusion message is to discard the message without disrupting normal connection processing.
+
+## 8.2 Nodal functions
+
+Interworking with AAL type 2 nodes that conform only to ITU-T Recs Q.2630.1 [15] or Q.2630.2 [16] is specified in Annex C; the procedures in the main body of this Recommendation exclusively describe the AAL type 2 signalling control protocol capability set 3.
+
+### 8.2.1 Nodal functions for AAL type 2 nodes with served user interaction
+
+#### 8.2.1.1 Connection control
+
+##### 8.2.1.1.1 Successful connection set up
+
+###### 8.2.1.1.1.1 Actions at the originating AAL type 2 service endpoint
+
+When the nodal function receives an ESTABLISH.request primitive from the AAL type 2 served user, the following parameters are mandatory:
+
+- Destination Endpoint Address; and
+- Transfer Capability.
+
+When the nodal function receives an ESTABLISH.request primitive from the AAL type 2 served user, the restrictions on the optionality of the parameters used only for interworking with CS-1 or CS-2 nodes is described in Annex C. These optional parameters are the following:
+
+- The Preferred Transfer Capability;
+- Transfer Capability Support;
+- Link Characteristics;
+- Preferred Link Characteristics;
+- Modify Support for Link Characteristics;
+- Preferred Service Specific Information;
+- Modify Support for Service Specific Information;
+- Service Specific Information (Audio); and
+- Service Specific Information (Multirate).
+
+No optionality restrictions apply to the other parameters.
+
+The nodal function analyses the routing information and selects a route with sufficient AAL type 2 path resources on a path with the requested path type (or network default if the path type is not specified) to the succeeding AAL type 2 node. It then selects an AAL type 2 path from within that route which is able to accommodate the new connection.
+
+NOTE 1 – Routing typically is based on:
+
+- Addressing information;
+- The Test Connection Indicator;
+- Transfer Capability;
+- Requested Path Type;
+- Automatic congestion control and the congestion level in the routing tables; and
+- Temporary Alternative Routing control (see ITU-T Rec. E.412 [17]).
+
+When the nodal function selects a route, the connection priority information, if received from the AAL Type 2 served user, is used to select a route that has sufficient AAL type 2 path resources to the succeeding AAL type 2 node.
+
+Under the normal condition, when the network is not congested and the AAL Type 2 service endpoint has the necessary resources to complete it, the connection establishment is processed without special treatments.
+
+NOTE 2 – In times of network congestion, when the AAL Type 2 service endpoint does not have sufficient resources to complete all of the incoming connection establishment requests, as one option, the AAL Type 2 service endpoint may give preferential treatments based on the priority level.
+
+NOTE 3 – The preferential treatment should include access to reserved network resources, e.g.:
+
+- the highest priority connections are given access to available network resources including the resources reserved for highest priority connections;
+- the second highest priority connections are given access to available network resources including the resources reserved for the second highest priority connections, except for the resources reserved for the highest priority connections, and so on.
+
+NOTE 4 – Allocation of reserved network resources to specific priority levels is implementation specific, and is not a subject for standardization.
+
+AAL type 2 service endpoint internal resources are allocated for the new connection from the originating AAL type 2 served user to the outgoing AAL type 2 path. The connection priority information, if received, is taken into consideration when allocating these resources.
+
+On the selected outgoing AAL type 2 path, the CID and other resources (e.g., indicated by the Transfer Capability parameter) are allocated for the outgoing AAL type 2 link. The handling of interworking with CS-1 and CS-2 nodes is specified in Annex C.
+
+The following parameters – if they were conveyed by the originating AAL type 2 served user – shall not be modified by the nodal function:
+
+- the Destination Service Endpoint Address;
+- the Origination Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the Transfer Capability;
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics;
+- the Modify Support for Link Characteristics;
+- the SSCS Information;
+- the Preferred SSCS Information;
+- the Modify Support for SSCS Information;
+- the Path Type;
+- the Connection Priority; and
+- the Test Connection Indicator.
+
+The following parameters – if they were conveyed by the originating AAL type 2 served user – have significance to the served user only; therefore, they shall not be examined by the nodal function:
+
+- the Origination Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+
+- the SSCS Information;
+- the Preferred SSCS Information; and
+- the Modify Support for SSCS Information.
+
+An outgoing protocol entity instance is invoked and the following parameters are passed to it:
+
+- the Destination AAL type 2 Service Endpoint Address;
+- the Transfer Capability;
+- the AAL type 2 Path Identifier; and
+- a CID value.
+
+The nodal function shall pass the following parameters to the outgoing protocol entity instance only if they were conveyed by the originating AAL type 2 served user:
+
+- the Origination AAL type 2 Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics;
+- the Modify Support for Link Characteristics;
+- the SSCS Information;
+- the Preferred SSCS Information;
+- the Modify Support for SSCS Information;
+- the Path Type;
+- the Connection Priority; and
+- the Test Connection Indicator.
+
+If the Temporary Alternative Routing control is applied a "TAR controlled connection" indication shall be passed to the outgoing protocol entity instance.
+
+If the hop counter procedure has been activated, a Hop Counter containing an initial count value shall be passed to the outgoing protocol entity instance. The initial count value of the Hop Counter shall be provisioned by the network operator on a per AAL type 2 node basis (31 maximum).
+
+NOTE 5 – Through-connection at AAL type 2 service endpoints is not specified by this Recommendation. It may be controlled by the AAL type 2 served user.
+
+After receiving an indication of the successful AAL type 2 connection setup from the outgoing protocol entity instance, an ESTABLISH.confirm primitive is sent to the AAL type 2 served user. If a Transfer Capability Support parameter, a Modify Support for Link Characteristics, or a Modify Support for SSCS Information parameter was received from the outgoing protocol instance, the respective parameter shall be included in the ESTABLISH.confirm primitive.
+
+###### **8.2.1.1.1.2 Actions at the destination AAL type 2 service endpoint**
+
+Upon receiving an indication from an incoming protocol entity instance requesting a new connection, the nodal function checks the availability of the CID value and other resources (e.g., indicated by the Transfer Capability parameter), in the incoming AAL type 2 path.
+
+NOTE 1 – In case of interworking, the Transfer Capability and the Preferred Transfer Capability may be generated by the AAL type 2 service endpoint (see Annex C).
+
+The following parameters – if they were conveyed by the incoming protocol entity instance – shall not be modified by the nodal function:
+
+- the Destination Service Endpoint Address;
+- the Origination Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the Transfer Capability;
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics;
+- the Modify Support for Link Characteristics;
+- the SSCS Information;
+- the Preferred SSCS Information;
+- the Modify Support for SSCS Information;
+- the Path Type;
+- the Connection Priority; and
+- the Test Connection Indicator.
+
+The following parameters – if they were conveyed by the incoming protocol entity instance – have significance to the served user only; therefore, they shall not be examined by the nodal function:
+
+- the Origination Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the SSCS Information;
+- the Preferred SSCS Information; and
+- the Modify Support for SSCS Information.
+
+If the Test Connection Indicator parameter is present, a "locally blocked" or "remotely blocked" AAL type 2 path shall be acceptable for the incoming connection.
+
+If the CID and the other resources are available for the new connection, they are allocated to the new connection and then the AAL type 2 service endpoint address is examined. The nodal function determines that the destination AAL type 2 service endpoint has been reached.
+
+When the nodal function checks the availability of resources in the incoming AAL type 2 path, the Connection Priority information, if received, is taken into consideration.
+
+Under the normal condition, when the network is not congested and the AAL Type 2 service endpoint has the necessary resources to complete it, the connection establishment is processed without special treatments (see Notes in 8.2.1.1.1.1).
+
+If a Temporary Alternative Routing (TAR) control parameter or a Hop Counter parameter is received, they shall be ignored.
+
+AAL type 2 service endpoint internal resources are allocated for the new connection from the incoming AAL type 2 path to the destination AAL type 2 served user. The connection priority information, if received, is taken into consideration when allocating these resources.
+
+The nodal function acknowledges the successful AAL type 2 connection establishment towards the incoming protocol entity instance. The nodal function shall pass the following parameters to the incoming protocol entity instance only if they were conveyed by the incoming protocol entity instance:
+
+- the Transfer Capability Support;
+- the Modify Support for Link Characteristics; and
+- the Modify Support for SSCS Information.
+
+An ESTABLISH.indication primitive is sent to the AAL type 2 served user to inform it of the successfully established new connection. The nodal function shall pass the following parameters to the destination AAL type 2 served user only if they were conveyed by the incoming protocol entity instance:
+
+- the Origination AAL type 2 Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the Transfer Capability;
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics;
+- the Modify Support for Link Characteristics;
+- the SSCS Information;
+- the Preferred SSCS Information;
+- the Modify Support for SSCS Information;
+- the Path Type;
+- the Connection Priority; and
+- the Test Connection Indicator.
+
+NOTE 2 – Through-connection at AAL type 2 service endpoints is not specified by this Recommendation. It may be controlled by the AAL type 2 served user.
+
+##### **8.2.1.1.2 Unsuccessful/abnormal connection setup**
+
+###### **8.2.1.1.2.1 Actions at the originating AAL type 2 service endpoint**
+
+If the AAL type 2 path selection or the allocation of a CID and other resources for the outgoing AAL type 2 link described in 8.2.1.1.1.1 fails, a RELEASE.confirm primitive is returned to the AAL type 2 served user with one of the following causes:
+
+- "Unallocated (unassigned) number";
+- "No route to destination";
+- "No circuit/channel available";
+- "Resource unavailable, unspecified";
+- "Network out of order"; or
+- "Temporary failure".
+
+NOTE – Path selection failure may be due to the unavailability of an AAL type 2 path with the requested path type.
+
+If AAL type 2 service endpoint internal resources are not available for the new connection, a RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause "Switching equipment congestion".
+
+If the AAL Type 2 service endpoint cannot complete a high priority connection establishment request even after application of the preferential treatment, a RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause "Resource unavailable, unspecified".
+
+Upon receiving a negative acknowledgement for the connection setup request from the outgoing protocol entity instance, all the resources associated with this AAL type 2 link are released and made available for new traffic. The association to the outgoing protocol entity instance is released.
+
+Features that enable a further connection attempt, involving the selection of a different AAL type 2 path within the same route or of an alternative route, may be implemented. Such reattempts may use the CEID parameter returned in the Release Confirm (RLC) message and may select a different AAL type 2 path within the same route only. If the CEID parameter specifies an AAL Type 2 path with insufficient resources available for the connection attempt, no connection attempt is made on that path.
+
+If no further connection attempt is made, the AAL type 2 service endpoint internal resources are released and a RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause received from the outgoing protocol entity instance.
+
+When an indication is received from the outgoing protocol entity that the establishment request has been rejected, and there has been a change in the level of congestion of the adjacent node, the routing tables in the nodal function shall be updated accordingly. The absence of an Automatic Congestion Control parameter indicates that there is no reported congestion in the adjacent node, whilst if the Automatic Congestion Control parameter is present it indicates whether congestion level 1 or 2 has been exceeded. After the routing tables have been updated, the Automatic Congestion Control parameter is discarded.
+
+Upon receiving an indication from the outgoing protocol entity instance that a timer has expired, the association to the outgoing protocol entity instance is released and a reset procedure is started (see 8.2.1.2.1.1 case 3 a). The AAL type 2 service endpoint internal resources are released. A RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause received from the outgoing protocol entity instance, i.e., "Recovery on timer expiry".
+
+###### **8.2.1.1.2.2 Actions at the destination AAL type 2 service endpoint**
+
+If resources on the incoming AAL type 2 path are not available, the nodal function requests the incoming protocol entity instance to reject the AAL type 2 connection with one of the following causes as applicable:
+
+- "Resource unavailable, unspecified"; or
+- "Requested circuit/channel not available".
+
+If the nodal function detects that the destination is not reachable it may issue a redirection request by rejecting the AAL type 2 connection with the cause "No route to destination" and include an alternative AAL type 2 path identifier in a Connection Element Identifier parameter.
+
+If the nodal function is aware that the SSCS parameters are not supported, it requests the incoming protocol entity instance to reject the AAL type 2 connection with the cause "AAL parameters cannot be supported".
+
+The association between the nodal function entity and its incoming protocol entity instance is released.
+
+If an AAL type 2 path is "locally blocked" and an indication from an incoming protocol entity instance of the request for a new connection other than a test connection is received, the following actions are taken:
+
+- 1) The indication of the request for a new connection establishment is ignored and the incoming protocol entity instance is instructed to terminate and enter state "Idle"; the association with the incoming protocol entity instance is released and an ERROR.indication primitive with the CEID and the cause "Temporary failure" is sent to layer management.
+- 2) The blocking procedure specified in 8.2.1.2.2.1 case b) is initiated for the AAL type 2 path on which the new connection was requested to be established.
+
+If an AAL type 2 path is "remotely blocked" and an indication from an incoming protocol entity instance of the request for a new connection other than a test connection is received, the following actions are taken:
+
+- 1) The AAL type 2 path is set to "remotely unblocked".
+
+NOTE – This procedure shall not be considered as the normal way to remove the "remotely blocked" condition.
+
+- 2) The incoming connection establishment request is processed normally, i.e., as if the AAL type 2 path was not "remotely blocked" to begin with.
+
+If AAL type 2 service endpoint internal resources are not available for the new connection, a negative acknowledgement for the connection setup request shall be returned to the incoming protocol entity instance with the cause "Switching equipment congestion". The resources allocated to the incoming AAL type 2 path are released and the association between the incoming protocol entity instance and the nodal function is released.
+
+If the AAL Type 2 service endpoint cannot complete a high priority connection establishment request even after application of the preferential treatment, a negative acknowledgement for the connection setup request shall be returned to the incoming protocol entity instance with the cause "Resource unavailable, unspecified". The resources allocated to the incoming AAL type 2 path are released and the association between the incoming protocol entity instance and the nodal function is released.
+
+Upon receiving an indication from an incoming protocol entity instance requesting a new connection and the connection request is to be rejected, the nodal function checks the level of congestion of the node. If either of the two congestion thresholds is exceeded, an Automatic Congestion Control parameter is passed to the protocol entity with the rejection indication. This parameter indicates the level of congestion (congestion level 1 or 2) to the adjacent AAL Type 2 node.
+
+##### **8.2.1.1.3 Normal connection release**
+
+###### **8.2.1.1.3.1 Actions at the AAL type 2 service endpoint that originates the release**
+
+When the nodal function at an AAL type 2 service endpoint receives a RELEASE.request primitive from the AAL type 2 served user, it requests the protocol entity instance to release the connection. The request carries the cause of the release which shall be "Normal, unspecified" in case of normal connection release or "AAL parameters cannot be supported" if the AAL type 2 served user determines that it cannot support the SSCS parameters.
+
+The Cause parameters shall not be modified by the nodal function.
+
+When a release is to be initiated, the nodal function checks the level of congestion of the node. If either of the two congestion thresholds is exceeded, an Automatic Congestion Control parameter is passed to the protocol entity with the release indication. This parameter indicates the level of congestion (congestion level 1 or 2) to the adjacent AAL Type 2 node.
+
+Upon acknowledgement of the successful connection release from the protocol entity instance, all the resources associated with this AAL type 2 link are released and made available for new traffic, and the AAL type 2 service endpoint internal resources are released. The association to the protocol entity instance is released.
+
+###### **8.2.1.1.3.2 Actions at the AAL type 2 service endpoint that receives the release**
+
+When the nodal function at an AAL type 2 service endpoint receives a request from a protocol entity instance to clear the connection, all the resources associated with this AAL type 2 link are released and made available for new traffic, and the AAL type 2 service endpoint internal resources are released. The release is confirmed to the protocol entity instance and a RELEASE.indication primitive with the cause received from the protocol entity instance is sent to the AAL type 2 served user. The Cause parameters shall not be modified by the nodal function. The association between the nodal function and the protocol entity instance is released.
+
+When a Release indication containing an Automatic Congestion Control parameter is received from the incoming or outgoing protocol entity, and there has been a change in the level of congestion of the adjacent node, the routing tables in the nodal function shall be updated according to the indicated congestion level. The absence of an Automatic Congestion Control parameter indicates that there is no reported congestion in the adjacent node, whilst if the Automatic Congestion Control parameter is present it indicates whether congestion level 1 or 2 has been exceeded. After the routing tables have been updated, the Automatic Congestion Control parameter is discarded.
+
+##### **8.2.1.1.4 Abnormal connection release procedures**
+
+When the nodal function at an AAL type 2 service endpoint receives an indication from the protocol entity instance that a timer has expired, the association to the protocol entity instance is released and a maintenance protocol entity instance is ordered to start a reset procedure.
+
+##### **8.2.1.1.5 Successful modification**
+
+NOTE 1 – Modification of connection resources and SSCS layer resources are mandatory capabilities in this Recommendation (as in ITU-T Rec. Q.2630.2 [16]). Modify Support parameters and the Transfer Capability Support parameter are only required for interworking with CS-1 and CS-2 nodes (see Annex C).
+
+NOTE 2 – The effect of SSCS information in AAL type 2 CS-3 nodes is restricted to the allocation, configuration and management of the respective SSCS layer resources in AAL type 2 CS-3 service endpoints.
+
+###### **8.2.1.1.5.1 Actions at the AAL type 2 service endpoint originating the modification request**
+
+When the nodal function receives a MODIFY.request primitive from the AAL type 2 served user, the following restrictions on the optionality of the parameters of the primitive apply:
+
+- A Transfer Capability parameter or an SSCS Information parameter must be present.
+- If a Transfer Capability parameter is present, this parameter has to refer to the same AAL type 2 transfer capability as the AAL type 2 Transfer Capability parameter in the ESTABLISH.request primitive.
+
+NOTE 1 – For example, if the AAL type 2 Transfer Capability parameter in the ESTABLISH.request primitive indicated a Variable Bandwidth Stringent Transfer Capability, the AAL type 2 Transfer Capability parameter in the MODIFY.request primitive, if present, may only indicate a Variable Bandwidth Stringent Transfer Capability.
+
+- If an SSCS Information parameter is present, this parameter has to refer to the same SSCS Information as the SSCS Information parameter in the ESTABLISH.request primitive.
+
+NOTE 2 – For example, if the SSCS Information parameter in the ESTABLISH.request primitive indicated an audio service specific information, the SSCS Information parameter in the MODIFY.request primitive, if present, may only indicate an audio service specific information.
+
+- If an SSCS Information parameter is present, it must be either an "SSCS Information (Audio Extended)" parameter or an "SSCS Information (Multirate Extended)" parameter.
+
+When the nodal function receives a MODIFY.request primitive from the AAL type 2 served user, the restrictions on the optionality of the Link Characteristics parameter that is used only for interworking with CS-1 or CS-2 nodes are described in Annex C.
+
+When the nodal function receives a MODIFY.request primitive from the AAL type 2 served user that conveys a Transfer Capability parameter, it checks the availability of resources indicated by the AAL type 2 connection resource in the AAL type 2 path. If the resources are available for the connection, they are reserved for the connection.
+
+The protocol entity instance is informed of the modification request. The nodal function shall pass the following parameters to the protocol entity instance only if they were conveyed by the AAL type 2 served user:
+
+- the Served User Correlation ID;
+- the Transfer Capability;
+- the Link Characteristics; and
+- the SSCS Information.
+
+The following parameters – if they were conveyed by the originating AAL type 2 served user – shall not be modified by the nodal function:
+
+- the Served User Correlation ID;
+- the Transfer Capability;
+- the Link Characteristics; and
+- the SSCS Information.
+
+The following parameters – if they were conveyed by the originating AAL type 2 served user – have significance to the served user only; therefore, they shall not be examined by the nodal function:
+
+- the Served User Correlation ID; and
+- the SSCS Information.
+
+After receiving an indication of the successful modification from the protocol entity instance and AAL type 2 connection resources were requested to be modified, the reserved additional resources are allocated to the connection or resources no longer required for this AAL type 2 connection are freed.
+
+A MODIFY.confirm primitive is then sent to the AAL type 2 served user. If a Served User Correlation ID parameter was received from the protocol entity instance, it shall be included in the MODIFY.confirm primitive. The Served User Correlation ID parameter has significance to the served user only; therefore, it shall not be examined by the nodal function.
+
+###### **8.2.1.1.5.2 Actions at the AAL type 2 service endpoint receiving the modification request**
+
+Upon receiving an indication from a protocol entity instance requesting modification of the AAL type 2 connection resource, i.e., a Transfer Capability parameter is conveyed, the nodal function checks the availability of resources indicated by the AAL type 2 connection resource information in the incoming AAL type 2 path. If the resources are available for the connection, they are reserved for the connection.
+
+NOTE – In case of interworking, the Transfer Capability may be generated by the AAL type 2 service endpoint (see Annex C).
+
+A MODIFY.indication primitive is sent to the AAL type 2 served user to inform it of the modification of AAL type 2 connection resource. The nodal function shall pass the following
+
+parameters to the AAL type 2 served user only if they were conveyed by the protocol entity instance:
+
+- the Served User Correlation ID;
+- the Transfer Capability;
+- the Link Characteristics; and
+- the SSCS Information.
+
+The following parameters – if they were conveyed by the originating AAL type 2 served user – have significance to the served user only; therefore, they shall not be examined by the nodal function:
+
+- the Served User Correlation ID; and
+- the SSCS Information.
+
+Upon receiving a MODIFY.response from the served user and AAL type 2 connection resources were requested to be modified, the reserved additional resources are allocated to the connection or resources no longer required for this AAL type 2 connection are freed. The nodal function acknowledges the successful AAL type 2 connection resource modification towards the protocol entity instance. If a Served User Correlation ID parameter was contained in the MODIFY.response primitive, this parameter is passed to the protocol entity. The Served User Correlation ID parameter has significance to the served user only; therefore, it shall not be examined by the nodal function.
+
+##### **8.2.1.1.6 Unsuccessful/abnormal modification**
+
+###### **8.2.1.1.6.1 Actions at the AAL type 2 service endpoint originating the modification request**
+
+If resources on the AAL type 2 path are not available, a MODIFY-REJECT.confirm primitive is returned to the AAL type 2 served user with the cause "Resource unavailable, unspecified".
+
+Upon receiving a negative acknowledgement for the modification request from the protocol entity instance, all additional resources reserved for the modification request are freed. A MODIFY-REJECT.confirm primitive is sent to the AAL type 2 served user with the cause received from the protocol entity instance. The Cause parameters shall not be modified by the nodal function.
+
+Upon receiving an indication from the outgoing protocol entity instance that a timer has expired, the association to the outgoing protocol entity instance is released and a reset procedure is started (see 8.2.1.2.1.1 case 3 a). The AAL type 2 service endpoint internal resources are released. A RELEASE.indication primitive is sent to the AAL type 2 served user with the cause received from the outgoing protocol entity instance, i.e., "Recovery on timer expiry".
+
+###### **8.2.1.1.6.2 Actions at the AAL type 2 service endpoint receiving the modification request**
+
+If the resources on the AAL type 2 path are not available, the nodal function requests the protocol entity instance to reject the AAL type 2 modification request with the cause "Resource unavailable, unspecified".
+
+##### **8.2.1.1.7 Connection release during modification**
+
+The release procedures take precedence over the modification procedures.
+
+###### **8.2.1.1.7.1 Actions at the AAL type 2 service endpoint**
+
+When the nodal function receives a RELEASE.request primitive from the AAL type 2 served user or an indication of connection release from the protocol entity instance during the modification procedures, the nodal function will continue with normal connection release procedures.
+
+#### 8.2.1.2 Maintenance control
+
+##### 8.2.1.2.1 Reset
+
+The reset procedure is invoked under abnormal conditions such as when the current status of the channels is unknown or ambiguous, for example, an AAL type 2 switching system that has suffered memory mutilation will not know the status of channels in one or several AAL type 2 paths. All the affected channels and any associated resources (e.g., bandwidth, etc.) between the two adjacent AAL type 2 nodes shall be released. The resources are made available for new traffic.
+
+The reset procedure covers the following three cases:
+
+- 1) Case 1: Reset all channels used for user plane traffic (see Note) in all AAL type 2 paths associated with a signalling transport association between two adjacent AAL type 2 nodes.
+- 2) Case 2: Reset all channels used for user plane traffic (see Note) in a single AAL type 2 path between two adjacent AAL type 2 nodes represented by an AAL type 2 Path Identifier.
+- 3) Case 3: Reset a single channel between two adjacent AAL type 2 nodes.
+
+NOTE – Channels used for user plane traffic refers to channels that are under the control of the AAL type 2 signalling entity. They are identified by CID values "8" ... "255". Other channels are unaffected by the reset procedure.
+
+The reset procedure should be initiated when:
+
+- a) Signalling anomalies are detected by the AAL type 2 signalling entity. The following anomalies are detected by the protocol procedures and are indicated to the nodal function:
+  - Timer "Timer\_ERQ" expiry – Action: Reset the single AAL type 2 channel associated with the outgoing protocol entity instance.
+  - Timer "Timer\_REL" expiry – Action: Reset the single AAL type 2 channel associated with the incoming or outgoing protocol entity instance.
+  - Timer "Timer\_MOD" expiry – Action: Reset the single AAL type 2 channel associated with the incoming or outgoing protocol entity instance.
+- b) Maintenance action is required to recover from abnormal conditions such as loss or ambiguity of association information (e.g., caused by memory mutilation) between SAID(s) and the channel status of either a specific channel in a specific AAL type 2 path, all channels in a specific AAL type 2 path, or all AAL type 2 paths associated with a signalling transport association between two AAL type 2 signalling nodes. Action: Reset a single AAL type 2 channel in a specific AAL type 2 path, all AAL type 2 channels in a single AAL type 2 path or all AAL type 2 channels in all AAL type 2 paths associated with a signalling transport association between two adjacent AAL type 2 nodes respectively.
+
+The reset procedures take precedence over the modification procedures.
+
+###### 8.2.1.2.1.1 Actions at reset initiating AAL type 2 node
+
+Reset procedures can be initiated to reset:
+
+- 1) all AAL type 2 paths associated with a signalling transport association between two adjacent AAL type 2 nodes,
+- 2) a specific AAL type 2 path;
+- 3) a single AAL type 2 channel.
+
+For case 1), layer management passes a RESET.request together with the indication "All AAL type 2 paths associated with a signalling transport association" to the nodal function which in turn invokes a maintenance protocol entity and passes a request for reset to that entity together with an indication that all AAL type 2 paths associated with a signalling transport association must be reset.
+
+For case 2), layer management passes a RESET.request together with the AAL type 2 path identifier to the nodal function which in turn invokes a maintenance protocol entity and passes a request for reset together with the AAL type 2 path identity.
+
+For case 3) there are two possible subcases, one due to timer expiry and the other due to layer management action:
+
+- a) After the expiry of Timer\_ERQ, Timer\_REL, or Timer\_MOD, the nodal function invokes a maintenance protocol entity by passing a request for a reset together with the identity of the AAL type 2 path and the channel.
+- b) Layer management invokes the nodal function which in turn invokes a maintenance protocol entity by passing a request for a reset together with the identity of the AAL type 2 path and the channel.
+
+In cases 1), 2), and 3 b), the nodal function requests any affected incoming or outgoing protocol entity instances to terminate and enter state "Idle". The associations to the incoming or outgoing protocol entity instances are released. The affected AAL type 2 served users are informed with a RELEASE.indication primitive with the cause "Temporary failure".
+
+For cases 1) and 2), the remote blocking state for the affected path(s) is set to "remotely unblocked".
+
+Upon receiving a reset confirmation from the maintenance protocol entity instance, the nodal function will make the affected resources available for new connections, and the AAL type 2 node internal resources are released. The association to the maintenance protocol entity instance is released. In case 3 a), a RESET.indication primitive with a CEID parameter is sent to layer management; in all other cases, a RESET.confirm primitive is sent to the layer management.
+
+NOTE – The local blocking states are not affected.
+
+###### **8.2.1.2.1.2 Actions at reset responding node**
+
+Upon receiving a reset indication from the maintenance protocol entity, the nodal function analyses the received information to determine which AAL type 2 channels are to be reset.
+
+- 1) If an indication that all AAL type 2 paths associated with a signalling transport association must be reset is received, then all AAL type 2 channels associated with a signalling transport association between the two adjacent AAL type 2 nodes are reset.
+- 2) If an indication that all the channels within the identified AAL type 2 path must be reset is received, all AAL type 2 channels within that path are reset.
+- 3) If an indication that a specific channel within an AAL type 2 path must be reset is received, only that channel is reset.
+
+In cases 1) and 2), for "locally blocked" AAL type 2 paths, blocking procedures (refer to 8.2.1.2.2.1 case b)) are initiated prior to the sending of the reset confirmation.
+
+If resources have been assigned to any of the channels that are reset, the nodal functions make the affected resources available for new connections, and the AAL type 2 node internal resources are released. It also returns a reset confirmation to the maintenance protocol entity. The association between the nodal function and the maintenance protocol entity instance is released. The nodal function informs layer management about the receipt of the reset request by sending a RESET.indication primitive with the same CEID parameter as has been received in the RES message (reset request).
+
+The nodal function also requests the affected incoming or outgoing protocol entity instances (if any) to terminate and enter state "Idle". The associations to the incoming or outgoing protocol entity instances are released. The affected AAL type 2 served user is informed with a RELEASE.indication primitive with the cause "Temporary failure".
+
+###### **8.2.1.2.1.3 Abnormal reset procedures**
+
+Upon receiving a negative acknowledgement with a cause "Switching equipment congestion" from the maintenance protocol entity instance, the nodal function repeats the request for the reset.
+
+Upon receiving a negative acknowledgement with another cause from the maintenance protocol entity instance, an ERROR.indication primitive including the cause received from the maintenance protocol entity instance and the CEID parameter is sent to layer management.
+
+Upon receiving a STOP-RESET.request primitive with adjacent AAL type 2 node identifier and connection element identifier parameters from layer management, the nodal function will make the affected resources available for new connections. The nodal function requests the maintenance protocol entity instance to terminate and enter state "Idle". The association between the nodal function and the maintenance protocol entity instance is released.
+
+##### **8.2.1.2.2 Blocking and unblocking of AAL type 2 paths**
+
+The AAL type 2 path blocking procedure is provided to prevent an AAL type 2 path from being selected for carrying new connections other than test connections. Existing connections on the AAL type 2 path are not affected.
+
+Blocking can be initiated by either signalling endpoint that controls an AAL type 2 path. When blocking is invoked, both ends of the AAL type 2 path are put into a blocked state. A blocked AAL type 2 path cannot be selected for new, non-test traffic by either AAL type 2 node.
+
+An acknowledgment is required for each blocking and unblocking request. The acknowledgment is not sent until the appropriate action – blocking or unblocking – has been taken.
+
+Unblocking can only be initiated by the same AAL type 2 node which initiated the blocking procedures. It is performed by sending an unblocking request. At either end, the blocked state is removed and the AAL type 2 path is made available again for all new connections.
+
+An AAL type 2 path is considered "unblocked" if it is both "locally unblocked" and "remotely unblocked".
+
+The blocking and unblocking procedures do not affect the modification procedures.
+
+###### **8.2.1.2.2.1 Initiating blocking**
+
+Blocking can be initiated either by layer management, by the reset procedure, or by the connection set up procedure.
+
+Case a): When a BLOCK.request primitive is received from layer management for an AAL type 2 path that is currently "locally unblocked", the AAL type 2 path becomes "locally blocked". The AAL type 2 path is made unavailable for the selection to accommodate new non-test connections.
+
+Case b): A request for blocking can also be received from the reset procedure (8.2.1.2.1.2) or from the connection set up procedure (8.2.1.1.2.2).
+
+In both cases, a maintenance protocol entity is then invoked and the AAL type 2 path identifier and a request for blocking is passed to it.
+
+When confirmation of the blocking is received from the maintenance protocol entity, a BLOCK.confirm primitive is sent to layer management and the association to the maintenance protocol entity instance is released.
+
+###### **8.2.1.2.2.2 Initiating unblocking**
+
+When an UNBLOCK.request is received from layer management for an AAL type 2 path that is currently "locally blocked", a maintenance protocol entity is invoked and the AAL type 2 path identifier and a request for unblocking is passed to it.
+
+When confirmation of the unblocking is received from the maintenance protocol entity, the AAL type 2 path becomes "locally unblocked" and the AAL type 2 path is made available again to accommodate new connections (if it is not "remotely blocked"). An UNBLOCK.confirm is sent to layer management and the association to the maintenance protocol entity instance is released.
+
+###### **8.2.1.2.2.3 Receiving blocking**
+
+When an indication of blocking is received from a maintenance protocol entity for an AAL type 2 path that is currently "remotely unblocked", the AAL type 2 path becomes "remotely blocked" and the AAL type 2 path is made unavailable to accommodate new non-test connections. A response is then sent to the maintenance protocol entity indicating the acceptance of the blocking and the association to the maintenance protocol entity instance is released.
+
+###### **8.2.1.2.2.4 Receiving unblocking**
+
+When an indication of unblocking is received from a maintenance protocol entity for an AAL type 2 path that is currently "remotely blocked", the AAL type 2 path becomes "remotely unblocked" and the AAL type 2 path is made available to accommodate new connections (if it is not "locally blocked"). A response is then issued to the maintenance protocol entity indicating the acceptance of the unblocking and the association to the maintenance protocol entity instance is released.
+
+###### **8.2.1.2.2.5 Abnormal blocking and unblocking procedures**
+
+- a) If an indication for blocking is received from a maintenance protocol entity for an AAL type 2 path which is already "remotely blocked", a blocking confirmation is sent to the maintenance protocol entity and the association to the maintenance protocol entity instance is released. No further actions are performed.
+- b) If an indication for unblocking is received from a maintenance protocol entity for an AAL type 2 path which is "remotely unblocked", an unblocking confirmation is sent to the maintenance protocol entity and the association to the maintenance protocol entity instance is released. No further actions are performed.
+- c) If a BLOCK.request primitive is received from layer management for an AAL type 2 path that is already "locally blocked", the procedure in 8.2.1.2.2.1 is performed.
+- d) If an UNBLOCK.request primitive is received from layer management for an AAL type 2 path that is already "locally unblocked", the procedure in 8.2.1.2.2.2 is performed.
+- e) If an indication of an error is received from the maintenance protocol entity, a BLOCK.confirm primitive or an UNBLOCK.confirm primitive with the cause received from the maintenance protocol entity instance is sent to layer management. The association to the maintenance protocol entity is released.
+
+##### **8.2.1.2.3 Transmission fault handling**
+
+Fully digital transmission systems are provided between all AAL type 2 nodes. They have some inherent fault indication features that give an indication to the switching system when faults are detected on the transmission path level and/or on the virtual path level. On receipt of a fault indication from layer management, the routing function in the switching system inhibits selection of the AAL type 2 path (or paths) concerned for the period that the fault condition persists. No special action is required for active connections.
+
+##### **8.2.1.2.4 AAL type 2 signalling entity signalling congestion control**
+
+On receipt of a CONGESTION.indication primitive from the generic signalling transport service, the AAL type 2 signalling entity should alter traffic load (e.g., connection attempts) toward the affected AAL type 2 nodes to align with the congestion level indicated by the primitive.
+
+##### **8.2.1.2.5 Adjacent AAL type 2 node availability**
+
+On receipt of an OUT-OF-SERVICE.indication primitive from the generic signalling transport service, the following action is required: All AAL type 2 paths to the affected adjacent AAL type 2 node are marked as unavailable in the routing function prohibiting new (test or user) connection establishments to that AAL type 2 node. Already established connections need not be released even though signalling messages cannot be sent to the affected node.
+
+On receipt of an IN-SERVICE.indication primitive from the generic signalling transport service, the following action is required: All AAL type 2 paths to the affected adjacent AAL type 2 node, that are both "locally unblocked" and "remotely unblocked", are again marked available in the routing function and any of the unallocated channels can be used for connections immediately consistent with the congestion level in the primitive. Reset procedures that may have started during the period of signalling isolation continue and ensure that affected channels are returned to state "Idle". Connections that are in state "Established" are unaffected.
+
+#### **8.2.1.3 Error handling**
+
+A message received indicating an AAL type 2 path or CID value that is not controlled by the nodal function shall be discarded and layer management shall be informed with an ERROR.indication primitive with a cause "Invalid information element contents".
+
+If a parameter is present more than once in a message where this parameter is allowed only once, only the first parameter shall be processed; all subsequent instances of the parameter shall be ignored.
+
+When receiving a message which does not contain the minimum set of parameters required to continue processing, a protocol error is reported to layer management with an ERROR.indication primitive with a cause "Mandatory information element is missing" and the message is discarded.
+
+### **8.2.2 Nodal functions for AAL type 2 nodes without served user interaction**
+
+#### **8.2.2.1 Connection control**
+
+##### **8.2.2.1.1 Successful connection setup**
+
+Upon receiving notification from an incoming protocol entity instance requesting a new connection, the nodal function checks the availability of the CID value and other resources (e.g., indicated by Transfer Capability parameter), in the incoming AAL type 2 path.
+
+NOTE 1 – In case of interworking, the Transfer Capability and the Preferred Transfer Capability may be generated by the AAL type 2 switch (see Annex C).
+
+If the Test Connection Indicator parameter is present, "locally blocked" or "remotely blocked" AAL type 2 paths shall be acceptable for the incoming connection.
+
+If the CID and the other resources are available for the incoming AAL type 2 link, the resources are allocated to the new connection.
+
+If the Hop Counter is received, and the hop counter procedure is activated, the nodal functions shall decrement the Hop Counter value by 1. If the result is greater than 0, the nodal function shall pass the updated Hop Counter to the outgoing protocol entity instance when it is invoked. If the Hop Counter is received, and the hop counter procedure is not activated, the nodal functions shall pass the Hop Counter unmodified to the outgoing protocol entity instance when it is invoked.
+
+NOTE 2 – If the result is 0, see 8.2.2.1.2.
+
+The AAL type 2 service endpoint address is then examined. The nodal function determines that the AAL type 2 connection needs to be routed further to reach the destination AAL type 2 service endpoint and analyses the routing information. It selects a route with sufficient AAL type 2 path resources on a path with the requested path type (or network default if the path type is not specified)
+
+to the next AAL type 2 node. It then selects an AAL type 2 path from within the route which is able to accommodate the new connection.
+
+NOTE 3 – Routing typically is based on:
+
+- Addressing information;
+- Transfer Capability;
+- Test Connection Indicator;
+- Requested Path Type;
+- Automatic congestion control and the congestion level in the routing tables; and
+- Temporary Alternative Routing (TAR) control (see ITU-T Rec. E.412 [17]).
+
+When the nodal function selects a route, the Connection Priority information, if received from the incoming protocol entity instance is used to select a route that has sufficient AAL type 2 path resources to the succeeding AAL type 2 node.
+
+If the "TAR controlled connection" indication is received, the nodal functions shall not apply network management Temporary Alternative Routing (TAR) to the same connection.
+
+If a Hop Counter is not received, and the hop counter procedure is activated, the nodal function shall pass the Hop Counter containing an initial count value to the outgoing protocol entity instance when it is invoked. The initial count value shall be provisioned by the network operator on a per AAL type 2 node basis (31 maximum).
+
+AAL type 2 node internal resources are allocated for the new connection from the incoming AAL type 2 path to the outgoing AAL type 2 path. The connection priority information, if received, is taken into consideration when allocating these resources.
+
+Under the normal condition, when the network is not congested and the AAL Type 2 node has the necessary resources to complete it, the connection establishment is processed without special treatments.
+
+NOTE 4 – In times of network congestion, when the AAL Type 2 node does not have sufficient resources to complete all of the incoming connection establishment requests, as one option, the AAL Type 2 node may give preferential treatments based on the priority level.
+
+NOTE 5 – The preferential treatment should include access to reserved network resources, e.g.:
+
+- the highest priority connections are given access to available network resources including the resources reserved for highest priority connections;
+- the second highest priority connections are given access to available network resources including the resources reserved for the second highest priority connections, except for the resources reserved for the highest priority connections, and so on;
+
+NOTE 6 – Allocation of reserved network resources to specific priority levels is implementation specific, and is not a subject for standardization.
+
+On the selected outgoing AAL type 2 path, the CID and other resources (e.g., indicated by Transfer Capability, Link Characteristics, or SSCS information) are allocated for the outgoing AAL type 2 link. The handling of Transfer Capability, Link Characteristics, and SSCS information is specified in Annex C.
+
+The following parameters – if they were conveyed by the incoming protocol entity instance – shall not be modified by the nodal function:
+
+- the Destination Service Endpoint Address;
+- the Origination Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the Transfer Capability;
+
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics;
+- the Modify Support for Link Characteristics;
+- the SSCS Information;
+- the Preferred SSCS Information;
+- the Modify Support for SSCS Information;
+- the Path Type;
+- the Connection Priority; and
+- the Test Connection Indicator.
+
+The following parameters – if they were conveyed by the incoming protocol entity instance – have significance to the served user only; therefore, they shall not be examined by the nodal function:
+
+- the Origination Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the SSCS Information;
+- the Preferred SSCS Information; and
+- the Modify Support for SSCS Information.
+
+An outgoing protocol entity instance is invoked and the following parameters are passed to it:
+
+- the Destination AAL type 2 Service Endpoint Address;
+- the AAL type 2 Path Identifier;
+- a CID value; and
+- the Transfer Capability.
+
+The nodal function shall pass the following parameters to the outgoing protocol entity instance only if they were conveyed by the incoming protocol entity instance:
+
+- the Origination AAL type 2 Service Endpoint Address;
+- the Served User Generated Reference;
+- the Served User Transport;
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics;
+- the Modify Support for Link Characteristics;
+- the SSCS Information;
+- the Preferred SSCS Information;
+- the Modify Support for SSCS Information;
+- the Path Type;
+- the Connection Priority; and
+- the Test Connection Indicator.
+
+A received "TAR controlled connection" indication shall be passed to the invoked outgoing protocol entity instance unchanged; alternatively, if the "TAR controlled connection" indication is not received and the nodal function applies network management Temporary Alternative Routing to the connection, the nodal function shall pass a "TAR controlled connection" parameter to the invoked outgoing protocol entity instance.
+
+If the Hop Counter has been received or generated by the nodal function, it is passed to the invoked outgoing protocol entity instance.
+
+Through-connection in both directions will then be completed.
+
+After receiving an indication of the successful AAL type 2 connection setup from the outgoing protocol entity instance, the incoming protocol entity instance is informed of the successful AAL type 2 connection setup. If one or more of the parameters Transfer Capability Support, Modify Support for Link Characteristics, or Modify Support for SSCS Information parameter, was received from the outgoing protocol instance they shall be conveyed to the incoming protocol entity instance.
+
+##### **8.2.2.1.2 Unsuccessful/abnormal connection setup**
+
+If resources on the incoming AAL type 2 path are not available, the nodal function requests the incoming protocol entity instance to reject the connection with one of the following causes as applicable:
+
+- "Resource unavailable, unspecified"; or
+- "Requested circuit/channel not available".
+
+The association between the nodal function entity and its incoming protocol entity instance is released.
+
+If an AAL type 2 path is "locally blocked" and an indication from an incoming protocol entity instance of the request for a new connection other than a test connection is received, the following actions are taken:
+
+- 1) The indication of the request for a new connection establishment is ignored and the incoming protocol entity instance is instructed to terminate and enter state "Idle"; the association with the incoming protocol entity instance is released and an ERROR.indication primitive with the CEID and the cause "Temporary failure" is sent to layer management.
+- 2) The blocking procedure specified in 8.2.1.2.2.1 case b) is initiated for the AAL type 2 path on which the new connection was requested to have been established.
+
+If an AAL type 2 path is "remotely blocked" and an indication from an incoming protocol entity instance of the request for a new connection other than a test connection is received, the following actions are taken:
+
+- 1) The AAL type 2 path is set to "remotely unblocked".
+
+NOTE 1 – This procedure shall not be considered as the normal way to remove the "remotely blocked" condition.
+
+- 2) The incoming connection establishment request is processed normally, i.e., as if the AAL type 2 path was not "remotely blocked" to begin with.
+
+If the Hop Counter is received, the nodal functions shall decrement the Hop Counter value by 1. If the result equals 0, the nodal function shall request the incoming protocol entity instance to reject the connection with cause value "exchange routing error". The association between the nodal function entity and its incoming protocol entity instance is released and all the resources associated with the incoming AAL type 2 link are released and made available for new traffic.
+
+In all cases where the request from an incoming protocol entity instance to establish a new connection has to be rejected, the nodal function checks the level of congestion of the node. If either of the two congestion thresholds is exceeded, an Automatic Congestion Control parameter is passed
+
+to the protocol entity with the rejection indication. This parameter indicates the level of congestion (congestion level 1 or 2) to the adjacent AAL Type 2 node.
+
+If AAL type 2 node internal resources are not available for the new connection, a negative acknowledgement for the connection setup request shall be returned to the incoming protocol entity instance with the cause "Switching equipment congestion". The resources allocated to the incoming AAL type 2 path are released and the association between the incoming protocol entity instance and the nodal function is released.
+
+If the AAL Type 2 node cannot complete a high priority connection establishment request even after application of the preferential treatment, a negative acknowledgement for the connection setup request shall be returned to the incoming protocol entity instance with the cause "Resource unavailable, unspecified". The resources allocated to the incoming AAL type 2 path are released and the association between the incoming protocol entity instance and the nodal function is released.
+
+If the AAL type 2 path selection or the allocation of a CID and other resources for the outgoing AAL type 2 link described in 8.2.2.1.1 fails, a negative acknowledgement for the connection setup request shall be returned to the incoming protocol entity instance with one of the following causes:
+
+- "Unallocated (unassigned) number";
+- "No route to destination";
+- "No circuit/channel available";
+- "Resource unavailable, unspecified";
+- "Network out of order"; or
+- "Temporary failure".
+
+NOTE 2 – Path selection failure may be due to the unavailability of an AAL type 2 path with the requested path type.
+
+The resources allocated to the preceding AAL type 2 path are released and the association between the incoming protocol entity instance and the nodal function is released.
+
+Upon receiving a negative acknowledgement from the outgoing protocol entity instance, all resources associated with the outgoing AAL type 2 link are released and made available for new traffic. The association to the outgoing protocol entity instance is released.
+
+Features that enable a further connection attempt, involving the selection of a different AAL type 2 path within the same route or of an alternative route, may be implemented. Such reattempts may use the CEID parameter returned in the Release Confirm (RLC) message and may select a different AAL type 2 path within the same route only. If the CEID parameter specifies an AAL Type 2 path with insufficient resources available for the connection attempt, no connection attempt is made on that path.
+
+If no further connection attempt is made, the AAL type 2 node internal resources are released, the rejection of the connection establishment is forwarded to the incoming protocol entity instance with the cause received from the outgoing protocol entity instance; a Connection Element Identifier parameter possibly received in the Release Confirm (RLC) message is not forwarded to the incoming protocol entity instance. All the resources associated with the incoming AAL type 2 link are freed. The association to the incoming protocol entity instance is released.
+
+When an indication is received from the outgoing protocol entity that the establishment request has been rejected, and there has been a change in the level of congestion of the adjacent node, the routing tables in the nodal function shall be updated accordingly. The absence of an Automatic Congestion Control parameter indicates that there is no reported congestion in the adjacent node, whilst if the Automatic Congestion Control parameter is present it indicates whether congestion
+
+level 1 or 2 has been exceeded. After the routing tables have been updated, the Automatic Congestion Control parameter is discarded.
+
+Upon receiving an indication from the outgoing protocol entity instance that a timer has expired, the association to the outgoing protocol entity instance is released and a reset procedure is started (see 8.2.1.2.1.1 case 3 a)). The AAL type 2 node internal resources are released. The rejection of the connection establishment is forwarded to the incoming protocol entity instance with the cause received from the outgoing protocol entity instance (i.e., "Recovery on timer expiry") and all the resources associated with the incoming AAL type 2 link are released and made available for new traffic. The association to the incoming protocol entity instance is released.
+
+##### **8.2.2.1.3 Normal connection release**
+
+When the nodal function has received a request from a (first) protocol entity instance to release the connection, an acknowledgement is returned to that protocol entity instance and all the resources associated with the AAL type 2 link being governed by the protocol entity instance are released and made available for new traffic. The association to the protocol entity instance is released.
+
+When a Release indication containing an Automatic Congestion Control parameter is received from the incoming or outgoing protocol entity, and there has been a change in the level of congestion of the adjacent node, the routing tables in the nodal function shall be updated according to the indicated congestion level. The absence of an Automatic Congestion Control parameter indicates that there is no reported congestion in the adjacent node, whilst if the Automatic Congestion Control parameter is present it indicates whether congestion level 1 or 2 has been exceeded. After the routing tables have been updated, the Automatic Congestion Control parameter is discarded.
+
+The AAL type 2 node internal resources are released.
+
+When a release is to be forwarded, the nodal function checks the level of congestion of the node. If either of the two congestion thresholds is exceeded, an Automatic Congestion Control parameter is passed to the protocol entity with the release indication. This parameter indicates the level of congestion (congestion level 1 or 2) to the adjacent AAL Type 2 node.
+
+The request to release the connection is forwarded to the companion incoming or outgoing (second) protocol entity instance with the Cause parameter received from the first protocol entity instance. The Cause parameter shall not be modified by the nodal function.
+
+After receiving the acknowledgement of the successful connection release from the second protocol entity instance, all the resources associated with the AAL type 2 link being governed by the protocol entity instance are released and made available for new traffic. The association to the protocol entity instance is released.
+
+##### **8.2.2.1.4 Abnormal connection release procedures**
+
+###### **8.2.2.1.4.1 Actions at the AAL type 2 switch that initiates the release**
+
+When the nodal function receives an indication from the second protocol entity instance that a timer has expired, the association to that protocol entity instance is released and a reset procedure is started (see 8.2.2.2.1.1, case 3 a).
+
+##### **8.2.2.1.5 Successful modification**
+
+NOTE 1 – In this clause the following conventions apply:
+
+- The term "AAL type 2 connection resource information" refers to Transfer Capability.
+- The term "modify receiving" refers to the AAL type 2 connection element identifier for which the Modify Request (MOD) message is received and the Modify Acknowledge (MOA) or Modify Reject (MOR) message is sent; conversely, the term "modify sending" refers to the AAL type 2 connection element identifier for which the Modify Request (MOD) message is sent and the Modify Acknowledge (MOA) or Modify Reject (MOR) message is received.
+
+NOTE 2 – The effect of SSCS information in AAL type 2 CS-3 nodes is restricted to the allocation, configuration and management of the respective SSCS layer resources in AAL type 2 CS-3 service endpoints.
+
+Upon receiving an indication from a protocol entity instance requesting modification of the AAL type 2 connection resource, i.e., a Transfer Capability parameter is conveyed, the nodal function checks the availability of the requested internal resources on the indicated AAL type 2 path. If the modification is requesting additional internal resources and they are available, they are reserved for the connection.
+
+NOTE 3 – In case of interworking, the Transfer Capability may be generated by the AAL type 2 switch (see Annex C).
+
+The nodal function checks the availability of the requested resources on the modify sending AAL type 2 path. If the modification is requesting additional resources and they are available, they are reserved for the connection.
+
+The companion (modify sending) protocol entity instance is informed of the modification. The nodal function shall pass the following parameters to the protocol entity instance only if they were conveyed by the AAL type 2 served user:
+
+- the Served User Correlation ID;
+- the Transfer Capability;
+- the Link Characteristics; and
+- the SSCS Information.
+
+The following parameters – if they were received from the modify receiving protocol entity – shall not be modified by the nodal function:
+
+- the Served User Correlation ID;
+- the Transfer Capability;
+- the Link Characteristics; and
+- the SSCS Information.
+
+The following parameters – if they were received from the modify receiving protocol entity– have significance to the served user only; therefore, they shall not be examined by the nodal function:
+
+- the Served User Correlation ID; and
+- the SSCS Information.
+
+After receiving an indication of the successful AAL type 2 connection resource modification from the modify sending protocol entity instance and AAL type 2 connection resources were requested to be modified, the nodal function allocates the reserved additional resources to the modify receiving and modify sending connection or frees resources no longer required for this AAL type 2 connection.
+
+The modify receiving protocol entity instance is informed of the successful modification. The nodal function shall pass the Served User Correlation ID parameter to the modify receiving protocol entity instance only if it was conveyed by the modify sending protocol entity instance. The Served User Correlation ID parameter has significance to the served user only; therefore, it shall not be examined by the nodal function.
+
+##### **8.2.2.1.6 Unsuccessful/abnormal modification**
+
+If additional resources on the modify receiving AAL type 2 path are not available, the nodal function requests the modify receiving protocol entity instance to reject the AAL type 2 modification request with the cause "Resource unavailable, unspecified".
+
+If the resources on the modify sending AAL type 2 path are not available, the nodal function requests the modify receiving protocol entity instance to reject the AAL type 2 modification request with the cause "Resource unavailable, unspecified". The additional resources reserved for the modify receiving AAL type 2 path are freed.
+
+Upon receiving a negative acknowledgement for the modification request from the modify sending protocol entity instance, the nodal function frees all the additional resources reserved for the modification request. The rejection of the modification is forwarded to the modify receiving protocol entity instance with the cause received from the modify sending protocol entity instance. The Cause parameters shall not be modified by the nodal function.
+
+Upon receiving an indication from the modify sending protocol entity instance that a timer has expired (in this case Timer\_MOD), the association to the modify sending protocol entity instance is released and a reset procedure is started (see 8.2.2.2.1.1 case 3 a)). The AAL type 2 node internal resources for this AAL type 2 connection are released. The nodal function requests the modify receiving protocol entity instance to release the connection with the cause "Recovery on timer expiry". All resources associated with the modify receiving AAL type 2 link are freed. The association to the modify receiving protocol entity instance is released.
+
+##### **8.2.2.1.7 Connection release during modification**
+
+The release procedures take precedence over the modification procedures.
+
+When the nodal function receives an indication of connection release from the modify receiving or modify sending protocol entity instance during the modification procedures, the nodal function will continue with normal connection release procedures.
+
+#### **8.2.2.2 Maintenance control**
+
+##### **8.2.2.2.1 Reset**
+
+Refer to 8.2.1.2.1.
+
+###### **8.2.2.2.1.1 Actions at reset initiating node**
+
+Reset procedures can be initiated to reset:
+
+- 1) all AAL type 2 paths between two adjacent AAL type 2 nodes associated with a signalling transport association;
+- 2) a specific AAL type 2 path;
+- 3) a single AAL type 2 channel.
+
+For case 1), layer management passes a RESET.request together with the indication "All AAL type 2 paths associated with a signalling transport association" to the nodal function which in turn invokes a maintenance protocol entity and passes the request for reset to that entity together with an indication that all AAL type 2 paths associated with a signalling transport association must be reset.
+
+For case 2), layer management passes a RESET.request together with the AAL type 2 path identifier to the nodal function which in turn invokes a maintenance protocol entity and passes a request for reset to that entity together with the identity of the AAL type 2 path.
+
+For case 3) there are two possible subcases, one due to timer expiry and the other due to layer management action:
+
+- a) After the expiry of Timer\_ERQ, Timer\_REL, or Timer\_MOD, the nodal function invokes a maintenance protocol entity by passing a request for a reset together with the identity of the AAL type 2 path and the channel.
+- b) Layer management invokes the nodal function which in turn invokes a maintenance protocol entity by passing a request for a reset together with the identity of the AAL type 2 path and the channel.
+
+In cases 1), 2), and 3 b), the nodal function requests any affected incoming or outgoing protocol entity instances to terminate and enter state "Idle". The associations to the incoming or outgoing protocol entity instances are released.
+
+For cases 1) and 2), the remote blocking state for the affected path(s) is set to "remotely unblocked".
+
+Upon receiving a reset confirmation from the maintenance protocol entity instance, the nodal function will make the affected resources available for new connections, and the AAL type 2 node internal resources are released. The association to the maintenance protocol entity instance is released. In case 3 a), a RESET.indication primitive with a CEID parameter is sent to layer management; in all other cases, a RESET.confirm primitive is sent to the layer management.
+
+NOTE – The local blocking states are not affected.
+
+###### **8.2.2.2.1.2 Actions at reset responding node**
+
+Upon receiving a reset indication from the maintenance protocol entity, the nodal functions analyses the received information to determine which AAL type 2 channels are to be reset.
+
+- 1) If an indication that all AAL type 2 paths associated with a signalling transport association must be reset is received, then all AAL type 2 channels associated with a signalling transport association between the two adjacent AAL type 2 nodes are reset.
+- 2) If an indication that all the channels within the identified AAL type 2 path must be reset is received, all AAL type 2 channels within that path are reset.
+- 3) If an indication that a specific channel within an AAL type 2 path must be reset is received, only that channel is reset.
+
+In cases 1) and 2), for "locally blocked" AAL type 2 paths, blocking procedures (refer to 8.2.1.2.2 case b)) are initiated prior to the sending of the reset confirmation.
+
+If resources have been assigned to one of the channels that are reset, the nodal functions make the affected resources available for new connections, and the AAL type 2 node internal resources are released. It also returns a reset confirmation to the maintenance protocol entity. The association between the nodal function and the maintenance protocol entity instance is released. The nodal function informs layer management about the receipt of the reset request by sending a RESET.indication primitive with the same CEID parameter as has been received in the RES message (Reset Request).
+
+The nodal function also requests the affected incoming or outgoing protocol entity instances (if any) to terminate and enter state "Idle". The associations to the incoming or outgoing protocol entity instances are released.

+## **8.3 Protocol entity**
+
+The following rules relating to Signalling Association Identifiers (SAID) apply:
+
+- The AAL type 2 signalling system that does not issue the value of such a field is not allowed to modify it, but shall use it in the destination signalling association identifier field in the header of a message directed towards the issuer.
+- When a message is received at the generic signalling transport service access point (GST-SAP), the destination signalling association identifier field of the incoming message is used to distribute the messages to the appropriate protocol entity instance.
+- If a received message contains a destination signalling association identifier set to the "unknown" value and an originating signalling association identifier, a new incoming protocol entity instance or a new maintenance protocol entity instance is created and marked with a newly allocated signalling association identifier. The originating signalling association identifier parameter in the first response message issued by the new protocol entity instance will inform the peer protocol entity instance of the newly allocated signalling association identifier.
+- If a new protocol entity instance is created by the nodal function, a signalling association identifier is allocated for it and the signalling association identifier is conveyed to the peer AAL type 2 signalling entity as the originating signalling association identifier parameter in the first message issued by the new protocol entity instance. The DSAID field in the header in this message is set to "unknown".
+- If a protocol entity instance sends a message to its peer, the message includes the signalling association identifier of the peer in the destination signalling association identifier field.
+- If a new maintenance protocol entity instance is created as a result of an incoming maintenance message, no signalling association identifier is allocated for it and no originating signalling association identifier parameter is conveyed to the peer AAL type 2 signalling entity in the first (and only) message issued by the new maintenance protocol entity instance.
+
+The sequence control parameter of the TRANSFER.request primitive across the GST-SAP is allocated on a cyclic basis per protocol entity instance.
+
+Example message sequences are shown in Appendix I where usage of originating and destination signalling association identifiers is also described.
+
+All messages are sent in a TRANSFER.request primitive. All messages are received in a TRANSFER.indication primitive.
+
+Appendix I provides examples for modification.
+
+### **8.3.1 General protocol error handling**
+
+If a message is received that is too short to contain a complete message (i.e., less than 6 octets), it shall be ignored.
+
+The message is discarded and layer management informed with an ERROR.indication in the following cases:
+
+- If the parameter length points beyond the end of the message – cause "Message with unrecognized parameter discarded" is indicated.
+- If the field length points beyond the end of the parameter – cause "Message with unrecognized parameter discarded" is indicated.
+- If an unrecognized message containing a destination signalling association identifier set to the "unknown" value – cause "Message type non-existent or not implemented" is indicated.
+
+NOTE – If an unrecognized message containing a valid destination signalling association identifier is received, the message is conveyed to the addressed protocol entity instance as if it were a recognized message.
+
+- If the message contains a destination signalling association identifier with an illegal/invalid value – cause "Invalid information element contents" is indicated.
+- If the message is considered unexpected by the signalling procedures – cause "Invalid message, unspecified" is indicated.
+- If a mandatory originating signalling association identifier parameter is not present – cause "Mandatory information element is missing" is indicated.
+- If the originating signalling association identifier field is set to "zero" – cause "Invalid information element contents" is indicated.
+
+### 8.3.2 Outgoing protocol procedures
+
+#### 8.3.2.1 Successful connection setup
+
+When an outgoing protocol entity instance in state "Idle" receives a request for a new connection from the nodal function, a free Signalling Association Identifier (SAID) is allocated for the outgoing protocol entity instance.
+
+Upon allocating an SAID, an ERQ message (establish request) is sent to the adjacent AAL type 2 node, entering state "Outgoing establishment pending" and starting Timer\_ERQ. The ERQ message contains a destination signalling association identifier field set to the "unknown" value and an originating signalling association identifier parameter in addition to those parameters given by the nodal function.
+
+If an ECF (establish confirm) message is received in state "Outgoing establishment pending", Timer\_ERQ is stopped, the nodal function is informed and state "Established" is entered.
+
+#### 8.3.2.2 Unsuccessful connection setup
+
+If the SAID allocation specified in section 8.3.2.1 fails, the nodal function is informed by passing the cause "Resource unavailable, unspecified".
+
+If the ERQ message (establish request) is longer than the signalling transport allows, the nodal function is informed by passing the cause ""Protocol error, unspecified". The SAID allocated to this particular outgoing protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+NOTE – If AAL type 2 signalling is used in an MTP3 signalling network (e.g., via the Signalling Transport Converter on MTP3 and MTP3b, see ITU-T Rec. Q.2150.1), it is possible that the ERQ message (establish request) may be longer than the minimum transport capability of 272 octets. This is due to the potential size of the Served User Transport (SUT) parameter. However, AAL type 2 signalling is specified to be deployed only in MTP3b networks.
+
+If Timer\_ERQ expires, the nodal function is informed by passing the cause "Recovery on timer expiry". The SAID allocated to this particular outgoing protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+If an RLC (release confirm) message is received in state "Outgoing establishment pending", the nodal function is informed about the rejection of the establishment request (including the cause and the Automatic Congestion Control parameter, if present, from the RLC message).
+
+Timer\_ERQ is stopped. The SAID allocated to this particular outgoing protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+#### **8.3.2.3 Normal connection release**
+
+In state "Established", an REL message (Release Request) containing a cause parameter can be received. The protocol entity instance informs the nodal function with the received cause and the Automatic Congestion Control parameter, if present. It then enters state "Incoming Release Pending". After the nodal function acknowledges the release, an RLC message (Release Confirm) is sent to the peer protocol entity instance (without a cause parameter). The SAID allocated to the protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+In state "Established", the nodal function can request the release of the connection. In this case an REL message is sent, Timer\_REL is started and state "Outgoing release pending" is entered. The REL message contains the cause received from the nodal function.
+
+If an RLC message is received, Timer\_REL is stopped and the nodal function is informed. The SAID allocated to the protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+#### **8.3.2.4 Release request collision**
+
+If an REL message (Release Request) is received in state "Outgoing Release Pending", an RLC message (Release Confirm) is immediately sent back to the peer protocol entity instance and state "Release Collision" is entered.
+
+When an RLC message is received in state "Release collision", Timer\_REL is stopped and the nodal function is informed. The SAID allocated to the protocol procedure entity instance is released and made available for new traffic and state "Idle" is entered.
+
+#### **8.3.2.5 Abnormal connection release procedures**
+
+If Timer\_REL expires in states "Outgoing release pending" or "Release collision", the nodal function is informed with a cause "Recovery on timer expiry". The SAID allocated to the protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+If in any state except state "Idle" a request to terminate an outgoing protocol procedure entity instance from the nodal function is received, all timers are stopped. The SAID allocated to the protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+#### **8.3.2.6 Successful modification**
+
+When an outgoing protocol entity instance in state "Established" receives a request for modification from the nodal function, an MOD message (Modify Request) is sent to the adjacent AAL type 2 node, entering state "Outgoing Modification Pending" and starting Timer\_MOD. The MOD message contains the DSAID which was received during the connection establishment phase and the parameter given by the nodal function, i.e., the Transfer Capability, Link Characteristics and/or SSCS information and the Served User Correlation ID if it was received from the nodal function.
+
+If an MOA (Modify Acknowledge) message is received in state "Outgoing Modification Pending", Timer\_MOD is stopped, the nodal function is informed of the successful modification, and the outgoing protocol entity instance returns to state "Established".
+
+Upon receiving an MOD message (Modify Request) in state "Established" with the DSAID which was received during the connection establishment phase, the outgoing protocol entity instance
+
+informs the nodal function of the request for the modification and state "Incoming Modification Pending" is entered.
+
+After receiving an acknowledgement from the nodal function that the connection modification is accepted, an MOA message (Modify Acknowledge) is sent to the preceding AAL type 2 node, and the outgoing protocol entity instance returns to state "Established".
+
+#### **8.3.2.7 Unsuccessful modification**
+
+If Timer\_MOD expires, the nodal function is informed by passing the cause "Recovery on timer expiry". The SAID allocated to this particular outgoing protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+If an MOR (Modify Reject) message is received in state "Outgoing Modification Pending", the nodal function is informed about the rejection of the modification request. Timer\_MOD is stopped and the outgoing protocol entity instance returns to state "Established".
+
+When an outgoing protocol entity instance in state "Incoming Modification Pending" receives a request to reject the requested modification from the nodal function, an MOR message is issued towards the adjacent AAL type 2 node with the cause provided by the nodal function. The MOD message contains the DSAID which was received during the connection establishment phase. The outgoing protocol entity instance returns to state "Established".
+
+#### **8.3.2.8 Connection release during modification**
+
+In state "Outgoing Modification Pending" or "Incoming Modification Pending", an REL message (Release Request) containing a cause parameter can be received. The normal connection release procedures specified in 8.3.2.3 shall apply.
+
+In state "Outgoing Modification Pending" or "Incoming Modification Pending", the nodal function can request the release of the connection. The normal connection release procedures specified in 8.3.2.3 shall apply.
+
+#### **8.3.2.9 Modification request collision**
+
+If an MOD message is received in state "Outgoing Modify Pending", an MOR message is immediately sent back to the peer protocol entity instance and "Modification Collision" state is entered.
+
+Clauses 8.3.2.7 and 8.3.2.8 shall apply with the replacement of "Modification Collision" with "Outgoing Modify Pending".
+
+#### **8.3.2.10 Unrecognized information procedures**
+
+When an unrecognized message, parameter, or subfield value is received, the message, the parameter, or the subfield value respectively is conveyed to the nodal function for appropriate action.
+
+When a request to pass on an unrecognized message, parameter, or subfield value is received from the nodal function, the unrecognized message is passed on and an unrecognized parameter or subfield value is sent in the recognized message being constructed respectively.
+
+When a request to send a CFN message (confusion) is received from the nodal function in any state except "Idle" and "Outgoing establishment pending", the message is sent. The CFN message (confusion) contains a cause parameter provided by the nodal function.
+
+When a request to send a cause parameter in an RLC message (release confirm) as a response to an unrecognized parameter or subfield value received in an REL message (release request) is received from the nodal function in any State except "Incoming release pending" and "Outgoing release pending", the cause parameter provided by the nodal function is sent in the RLC message (release confirm).
+
+When a CFN message (confusion) is received in any state except "Idle", the message is conveyed to the nodal function for appropriate action.
+
+When a cause parameter is received in an RLC message (release confirm) in state "Outgoing release pending", the cause parameter is conveyed to the nodal function for appropriate action.

+
+The diagram illustrates the outgoing protocol procedure (Process OPP2b) starting from an 'Established' state. It branches into four main paths based on input: 'RELEASE. request' (from nodal function), 'MODIFY. request' (from nodal function), 'TERMINATE. request' (from nodal function), and 'TRANSFER. indication (message)' (from Generic Signalling Transport). The 'RELEASE. request' path involves setting a timer (t2), constructing a REL message, and transitioning to 'Outgoing Release Pending'. The 'MODIFY. request' path involves setting a timer (t6), constructing a MOD message, and transitioning to 'Outgoing Modify Pending'. The 'TERMINATE. request' path releases the SAID and returns to an 'Idle' state. The 'TRANSFER. indication' path checks the message type; if 'REL', it sends a 'RELEASE. indication' to 'Incoming Release Pending'; if 'MOD', it sends a 'MODIFY. indication' to 'Incoming Modify Pending'; otherwise, it goes to state A1. From 'Outgoing Release Pending', the process can handle a 'Timer\_REL' (sending an 'ERROR. indication' to nodal function), a 'TERMINATE. request' (resetting the timer, releasing the SAID, and returning to 'Idle'), or a 'TRANSFER. indication (message)' from transport. This second 'TRANSFER. indication' leads to a 'message.type' decision; if 'REL', it constructs an RLC message and transitions to 'Release Collision'; if 'RLC', it resets the timer, sends a 'RELEASE. confirm' to nodal function, releases the SAID, and returns to 'Idle'; otherwise, it goes to state A1.

+The diagram illustrates the outgoing protocol procedure for Process OPP2b. It begins with an initial state leading to 'Incoming Release Pending'. From here, three paths emerge: 'RELEASE. response' (from nodal function), 'TERMINATE. request', and 'TRANSFER. indication (message)' (from Generic Signalling Transport). The 'RELEASE. response' path leads to 'Construct RLC message', which then becomes 'TRANSFER. request (RLC message)' (to Generic Signalling Transport), followed by 'release SAID' and an 'Idle' state. The 'TERMINATE. request' path leads directly to 'release SAID' and 'Idle'. The 'TRANSFER. indication (message)' path leads to a junction point 'A1'. A second initial state, 'Release Collision', leads to 'Timer\_REL', 'TERMINATE. request' (from nodal function), and 'TRANSFER. indication (message)' (from Generic Signalling Transport). 'Timer\_REL' leads to 'ERROR. indication (Cause)' (to nodal function), which then leads to 'reset (Timer\_REL)', 'release SAID', and 'Idle'. 'TERMINATE. request' leads to 'reset (Timer\_REL)', 'release SAID', and 'Idle'. 'TRANSFER. indication (message)' leads to a decision 'RLC message.type'. If 'else', it leads to junction 'A1'. If 'RLC', it leads to 'reset (Timer\_REL)', 'RELEASE. confirm' (to nodal function), 'release SAID', and 'Idle'.

+### **8.3.3 Incoming protocol procedures**
+
+#### **8.3.3.1 Successful connection setup**
+
+Upon receiving an ERQ message (establish request) in state "Idle" with the DSAID set to "unknown", a Signalling Association Identifier (SAID) is allocated for the new incoming protocol entity instance.
+
+The incoming protocol entity instance informs the nodal function of the request for a new connection and state "Incoming establishment pending" is entered.
+
+After receiving an acknowledgement from the nodal function that the connection establishment is accepted, an ECF message (establish confirm) is sent to the preceding AAL type 2 node and state "Established" is entered.
+
+#### **8.3.3.2 Unsuccessful connection setup**
+
+If a Signalling Association Identifier (SAID) allocation for the incoming protocol entity instance fails, an RLC message (release confirm) is returned containing the cause "Resource unavailable, unspecified".
+
+If a request to terminate the connection establishment from the nodal function is received, the SAID allocated to this particular incoming protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+If the nodal function informs the incoming protocol entity instance that the connection establishment is not accepted, an RLC message is issued towards the preceding AAL type 2 node with the cause and optionally the Automatic Congestion Control parameter provided by the nodal function. The SAID allocated to this particular incoming protocol entity instance is released and made available for new traffic and state "Idle" is entered.

+
+The diagram illustrates the state transitions and message exchanges for Process IPP2b. It starts in the 'Idle' state. Upon receiving a 'TRANSFER.indication (message)' from Generic Signalling Transport, it checks the 'message.type'. If it's an 'ERQ', it sends an 'ERROR.indication (Cause)' to layer management and returns to 'Idle'. If not an 'ERQ', it attempts to 'allocate SAID'. If allocation is successful, it sends an 'ESTABLISH.indication' to the nodal function, enters 'Incoming Establishment Pending', constructs an 'RLC message', sends a 'TRANSFER.request (RLC message)' to Generic Signalling Transport, and returns to 'Idle'. If allocation fails, it constructs an 'RLC message', sends a 'TRANSFER.request (RLC message)', and returns to 'Idle'. If the 'message.type' is not 'ERQ', it sends an 'ERROR.indication (Cause)' to layer management and enters 'Incoming Establishment Pending'. From 'Incoming Establishment Pending', it receives a 'TRANSFER.indication (message)'. This leads to either an 'ESTABLISH.response' (which results in constructing an 'ECF message', sending a 'TRANSFER.request (ECF message)', and reaching 'Established'), a 'TERMINATE.request' (leading to 'release SAID' and 'Idle'), or a 'RELEASE.response' (leading to constructing an 'RLC message', sending a 'TRANSFER.request (RLC message)', 'release SAID', and 'Idle').

+
+The SDL diagram describes the 'Incoming Release Pending' and 'Release Collision' states for Process IPP2b. In 'Incoming Release Pending', receiving a 'RELEASE. response' from the nodal function triggers constructing an RLC message, sending a 'TRANSFER. request' to transport, releasing the SAID, and returning to 'Idle'. A 'TERMINATE. request' also leads to releasing the SAID and 'Idle'. A 'TRANSFER. indication' from transport leads to connector 'A1'. In the 'Release Collision' state, three events are handled: 1) 'Timer\_REL' expiry leads to an 'ERROR. indication' to the nodal function, releasing SAID, and 'Idle'. 2) A 'TERMINATE. request' from the nodal function resets 'Timer\_REL', releases SAID, and goes to 'Idle'. 3) A 'TRANSFER. indication' from transport checks the message type; if it is 'RLC', 'Timer\_REL' is reset, a 'RELEASE. confirm' is sent to the nodal function, SAID is released, and the process enters 'Idle'. If the message type is not 'RLC', it transitions to connector 'A1'.

+### **8.3.4 Maintenance protocol procedures**
+
+#### **8.3.4.1 Reset**
+
+##### **8.3.4.1.1 Sending reset**
+
+When a request for reset is received from the nodal function, a maintenance protocol entity instance is created and an SAID allocated to it.
+
+If the request indicates all AAL type 2 paths associated with a signalling transport association are to be reset, a RES message (Reset Request) containing the Connection Element Identifier parameter – with both the Path Identifier and the Channel Identifier coded with a "Null" value – is sent to the adjacent AAL type 2 node.
+
+If the request contains the identity of an AAL type 2 path with the channel identifier coded with a "Null" value, a RES message containing the connection element identifier parameter – with the path identifier set to indicate the path and the channel identifier coded with the "Null" value – is sent to the adjacent AAL type 2 node.
+
+If the request contains the identity of a path and a channel, a RES message containing the connection element identifier parameter – with the path identifier set to indicate the path and the channel identifier set to indicate the channel – is sent to the adjacent AAL type 2 node.
+
+When the RES message is sent, Timer\_RES is started and state "Outgoing reset pending" is entered.
+
+If an RSC message (reset confirm) is received in state "Outgoing reset pending", a reset confirmation is passed to the nodal function and Timer\_RES is stopped. The SAID allocated to the maintenance protocol entity instance is released and made available for new traffic. The maintenance protocol entity instance enters state "Idle".
+
+##### **8.3.4.1.2 Receiving reset**
+
+When a RES message (reset request) is received, a maintenance protocol entity instance will be invoked.
+
+If the Path Identifier field in the CEID parameter included in the RES message is coded with the "Null" value, an indication that all AAL type 2 paths associated with the signalling transport association must be reset is passed to the nodal function.
+
+If the path identifier field in the CEID parameter included in the RES message is coded with a "non-Null" value but the channel identifier field with a "Null" value, an indication that all channels within the AAL type 2 path must be reset is passed to the nodal function.
+
+If the RES message contains the CEID parameter with both a "non-Null" path identifier field and a "non-Null" channel identifier field, an indication that the channel within the identified path must be reset is passed to the nodal function.
+
+After notifying the nodal function, state "Incoming reset pending" is entered.
+
+When a Reset response is received from the nodal function, a RSC message (reset confirm) is sent to the peer protocol entity instance. The maintenance protocol entity instance enters state "Idle".
+
+##### **8.3.4.1.3 Exceptional reset procedures**
+
+If the SAID allocation fails, the nodal function is informed with a cause "Switching equipment congestion" and the maintenance protocol entity instance enters state "Idle".
+
+When Timer\_RES expires in state "Outgoing reset pending", the RES message is sent again, the nodal function is informed with a cause "Recovery on timer expiry", state "Outgoing reset continuing" is entered, and Timer\_RES is started again.
+
+When Timer\_RES expires in state "Outgoing reset continuing", the RES message is sent again and Timer\_RES is started again; the nodal function is not informed.
+
+When an RSC message (reset confirm) is received in state "Outgoing reset continuing", a reset confirmation is passed to the nodal function and Timer\_RES is stopped. The SAID allocated to the maintenance protocol entity instance is released and made available for new traffic. The maintenance protocol entity instance enters state "Idle".
+
+When a request to terminate the repetition of the reset procedure is received, Timer\_RES is stopped. The SAID allocated to the maintenance protocol entity instance is released and made available for new traffic. The maintenance protocol entity instance enters state "Idle".
+
+##### 8.3.4.1.4 State transition model
+
+The state transition diagram for the reset procedure is shown in Figure 8-5.
+
+![State transition diagram for the maintenance control procedure (reset). The diagram shows four states: Idle, Outgoing reset pending, Outgoing reset continuing, and Incoming reset pending. Transitions are triggered by messages like RESET.request, RESET.confirm, RESET.response, and RES message, or by timer expiration (Timer_RES).](ff87509cc2b267501d910a2d9f9054ac_img.jpg)

+
+The diagram illustrates the state transitions for the maintenance control procedure (reset). It consists of four states: Idle, Outgoing reset pending, Outgoing reset continuing, and Incoming reset pending. Transitions are triggered by specific messages or timer expiration. The Idle state is the initial state. Transitions to Outgoing reset pending and Incoming reset pending lead to the Reset state, while transitions to Outgoing reset continuing lead to the Idle state.

+
+#### 8.3.4.2 Blocking and unblocking of AAL type 2 paths
+
+##### 8.3.4.2.1 Sending blocking/unblocking
+
+When a request for blocking is received from the nodal function, a new maintenance protocol entity instance is created, a new SAID is allocated and a BLO message (block request) is sent to the peer AAL type 2 signalling entity. The BLO message contains a connection element identifier with the path identifier coded to indicate the AAL type 2 path to be blocked (as instructed from the nodal function) and the channel identifier coded with the "Null" value. Timer\_BLO is started and state "Outgoing block pending" is entered.
+
+When a BLC message (block confirm) is received from the peer AAL type 2 signalling entity in state "Outgoing block pending", a confirmation of blocking is sent to the nodal function and Timer\_BLO is stopped. The SAID allocated to the maintenance procedure entity instance is released and made available for new traffic and state "Idle" is entered.
+
+When a request for unblocking is received from the nodal function, a new maintenance protocol entity instance is created, a new SAID is allocated and an UBL message (unblock request) is sent to the peer AAL type 2 signalling entity. The UBL message contains a connection element identifier with the path identifier coded to indicate the AAL type 2 path to be unblocked (as instructed from the nodal function) and the channel identifier coded with the "Null" value. Timer\_UBL is started and state "Outgoing unblock pending" is entered.
+
+When a UBC message (unblock confirm) is received from the peer AAL type 2 signalling entity in state "Outgoing unblock pending", a confirmation of unblocking is sent to the nodal function and Timer\_UBL is stopped. The SAID allocated to the maintenance protocol entity instance is released and made available for new traffic and state "Idle" is entered.
+
+##### 8.3.4.2.2 Receiving blocking/unblocking
+
+When a BLO message (block request) is received from the peer AAL type 2 signalling entity, a new maintenance protocol entity instance is created, an indication of the blocking is sent to the nodal function and state "Incoming block pending" is entered.
+
+When a response to the blocking is received from the nodal function in state "Incoming block pending", a BLC message (block confirm) is sent to the peer AAL type 2 signalling entity and state "Idle" is entered.
+
+When a UBL message (unblock request) is received from the peer AAL type 2 signalling entity, a new maintenance protocol entity instance is created, an indication of the unblocking is sent to the nodal function and state "Incoming unblock pending" is entered.
+
+When a response to the unblocking is received from the nodal function in state "Incoming unblock pending", a UBC message (unblock confirm) is sent to the peer AAL type 2 signalling entity and state "Idle" is entered.
+
+##### 8.3.4.2.3 Exceptional blocking and unblocking procedures
+
+If the SAID allocation fails, the nodal function is informed with a cause "Switching equipment congestion" and the maintenance protocol entity instance enters state "Idle".
+
+If Timer\_BLO expires, the nodal function is informed with a cause "Recovery on timer expiry", the SAID is released, and state "Idle" is entered.
+
+If Timer\_UBL expires, the nodal function is informed with a cause "Recovery on timer expiry", the SAID is released, and state "Idle" is entered.
+
+##### 8.3.4.2.4 State transition
+
+The state transition diagram for the path blocking procedure is shown in Figure 8-6.
+
+![State transition diagram for the maintenance control procedure (blocking and unblocking). The diagram shows four states: Idle, Outgoing block pending, Incoming block pending, Outgoing unblock pending, and Incoming unblock pending. Transitions are triggered by messages (BLOCK.request, BLC.confirm, BLO.indication, UNBLOCK.request, UBC.confirm) and timers (Timer_BLO, Timer_UBL).](d3f0eb93239fde2cb96b2baf46d62d6c_img.jpg)

+  
+```
+
+The diagram illustrates the state transitions for the maintenance control procedure. It starts with an initial state leading to 'Idle'. From 'Idle', a 'BLOCK.request' message triggers a transition to 'Outgoing block pending', where a 'BLO message' is sent and 'Timer\_BLO' starts. A return to 'Idle' occurs upon receiving a 'BLC message' (BLOCK.confirm) and stopping 'Timer\_BLO', or if 'Timer\_BLO' expires with an 'ERROR.indication'. Another transition from 'Idle' to 'Incoming block pending' is triggered by a 'receive BLO message' (BLOCK.indication), returning to 'Idle' upon a 'BLOCK\_response' (send BLC message). Similarly, a 'UNBLOCK.request' message triggers a transition to 'Outgoing unblock pending', where a 'UBL message' is sent and 'Timer\_UBL' starts. A return to 'Idle' occurs upon receiving a 'UBC message' (UNBLOCK.confirm) and stopping 'Timer\_UBL', or if 'Timer\_UBL' expires with an 'ERROR.indication'. Finally, a 'receive UBL message' (UNBLOCK.indication) triggers a transition to 'Incoming unblock pending', returning to 'Idle' upon a 'UNBLOCK\_response' (send UBC message). The states are grouped into 'Idle', 'Block', and 'Unblock' categories on the right side of the diagram.
+
+State transition diagram for the maintenance control procedure (blocking and unblocking). The diagram shows four states: Idle, Outgoing block pending, Incoming block pending, Outgoing unblock pending, and Incoming unblock pending.

+#### **8.3.4.3 Unrecognized information procedures**
+
+When an unrecognized message, parameter, or subfield value is received, the message, the parameter, or the subfield value respectively is conveyed to the nodal function for the appropriate action.
+
+If a request to send a notification of receipt of unrecognized information is received from the nodal function, the BLC message (block confirm), UBC message (unblock confirm), or RSC message (reset confirm) shall contain the cause received from the nodal function.
+
+When a cause parameter is received in a BLC message (block confirm), UBC message (unblock confirm), or RSC message (reset confirm), the cause parameter is conveyed to the nodal function for the appropriate action.
+
+#### **8.3.4.4 SDL diagrams for the maintenance control procedures**

+The SDL diagram for the maintenance control procedure is shown in Figure 8-7 (parts 1 to 4).
+
+The SDL diagrams contained in Figure 8-7 (parts 1 to 4) are an introduction to the procedures described in detail in 8.3.4.
+
+![SDL diagram for the maintenance control procedure. The diagram starts with an 'Idle' state. Three parallel transitions are shown: RESET.request, BLOCK.request, and UNBLOCK.request. Each transition involves allocating a SAID, checking if successful, setting a timer, constructing a message, and transferring it. RESET leads to RES message, BLOCK to BLO message, and UNBLOCK to UBL message. All three lead to 'Outgoing' pending states. A separate path labeled 'A3' shows a 'message.type' decision leading to 'UNRECOGNIZED' or 'ERROR' indications.](235e996e83e7d5198cf9d909f5713cdd_img.jpg)

+SDL diagram for the maintenance control procedure. The diagram starts with an 'Idle' state. Three parallel transitions are shown: RESET.request, BLOCK.request, and UNBLOCK.request. Each transition involves allocating a SAID, checking if successful, setting a timer, constructing a message, and transferring it. RESET leads to RES message, BLOCK to BLO message, and UNBLOCK to UBL message. All three lead to 'Outgoing' pending states. A separate path labeled 'A3' shows a 'message.type' decision leading to 'UNRECOGNIZED' or 'ERROR' indications.

+
+The diagram illustrates the state transitions for Process MCP2. It begins with an initial state labeled 'Idle'. A transition arrow points from 'Idle' to a message box labeled 'TRANSFER. indication (message)'. A dashed box to the left of this message box contains the text 'from Generic Signalling Transport'. Below the message box is a decision diamond labeled 'message.type'. Three arrows branch out from this diamond, labeled 'RES', 'BLO', and 'UBL'. The 'RES' arrow points to a message box labeled 'RESET. indication', which then points to a state box labeled 'Incoming Reset Pending'. Below this state box is a dashed box containing the text 'to nodal function'. The 'BLO' arrow points to a message box labeled 'BLOCK. indication', which then points to a state box labeled 'Incoming Block Pending'. Below this state box is a dashed box containing the text 'to nodal function'. The 'UBL' arrow points to a message box labeled 'UNBLOCK. indication', which then points to a state box labeled 'Incoming Unblock Pending'. Below this state box is a dashed box containing the text 'to nodal function'. A large dashed box encloses the 'RESET. indication', 'Incoming Reset Pending', and 'to nodal function' components, as well as the 'BLOCK. indication', 'Incoming Block Pending', and 'to nodal function' components. Another dashed box encloses the 'UNBLOCK. indication', 'Incoming Unblock Pending', and 'to nodal function' components.

+
+## A.1 Introduction
+
+The AAL type 2 signalling protocol described in this Recommendation can be deployed in support of a non-switched scenario as depicted in Figure A.1.

+
+**Figure A.1/Q.2630.3 – Non-switched scenario**
+
+In this scenario, AAL type 2 paths are typically provisioned – with each originating AAL type 2 service endpoint having one signalling transport association with each neighbouring AAL type 2 service endpoint. There is no AAL type 2 switch used in this scenario.
+
+This annex describes the subset of the signalling requirements needed to support the non-switched scenario. Because most signalling procedures are link-by-link, there are few differences from the switched scenario. Since the non-switched scenario is a subset of the switched scenario, there are no additional requirements to support non-switched.

+Subclauses below correspond with similarly numbered subclauses in the body of ITU-T Rec. Q.2630.1 [15].

+
+## **A.5 General framework of the AAL type 2 signalling protocol**
+
+The AAL type 2 signalling protocol provides the signalling capability to establish, release and maintain AAL type 2 point-to-point connections across a single ATM VCC that carries AAL type 2 links. These services are accessible via the AAL type 2 User Service Access Point (A2SU-SAP).
+
+Two peer AAL type 2 signalling entities rely on the generic signalling transport service to provide assured data transfer between them and service availability indications. These services are accessible via the Generic Signalling Transport Service Access Point (GST-SAP).
+
+NOTE – Primitives over the A2SU-SAP, GST-SAP, and LM-SAP are used for descriptive purpose only. They do not imply a specific implementation.
+
+Both peer AAL type 2 signalling entities provide the same set of services.
+
+The AAL type 2 signalling entity is subdivided into protocol entities and nodal functions as shown in Figure A.5-1. At each AAL type 2 service endpoint, the AAL type 2 signalling entity communicates with the AAL type 2 served user.
+
+![Diagram of AAL type 2 signalling protocol reference architecture for the non-switched scenario. The diagram shows two identical stacks of protocol layers connected by a dashed line representing an 'AAL type 2 signalling message'. Each stack consists of: an 'AAL type 2 service endpoint' at the top, followed by an 'AAL type 2 served user' block; an 'A2SU-SAP' interface; an 'AAL type 2 signalling entity' block containing 'Nodal function' and 'Protocol entity' sub-blocks; an 'LM-SAP' interface connected to a 'Layer management' block; a 'GST-SAP' interface; a 'Signalling transport converter' block (with a '(Note)' label); and finally, a 'Signalling transport' block at the bottom, which includes examples like 'MTP3b + NNI-SAAL, UNI-SAAL, SSCOP, ...'. The 'Protocol entity' blocks in both stacks are connected to this common 'Signalling transport' block.](c7111699f84f3e2bc4016b7876f10de6_img.jpg)

+
+NOTE – A signalling transport converter instance is associated with each AAL type 2 signalling transport.
+
+**Figure A.5-1/Q.2630.3 – AAL type 2 signalling protocol reference architecture for the non-switched scenario**
+
+Protocol Entities define the interactions between two adjacent AAL type 2 nodes. AAL type 2 messages are exchanged between peer protocol entities using the generic signalling transport service.
+
+The AAL type 2 signalling is independent of the signalling transport, although an assured data transport is required and a message size limit applies. To adapt the signalling transport services to a specific signalling transport service, a signalling bearer converter may be needed. The specification of signalling bearer converters is beyond the scope of this Recommendation (see ITU-T Recs Q.2150.0 [12], Q.2150.1 [22], and Q.2150.2 [23]).
+
+The protocol entity is divided into several procedures as shown in Figure A.5-2.
+
+![Diagram of the internal structure of the AAL type 2 signalling protocol entity. A large box labeled 'Protocol entity' contains three smaller boxes: 'Outgoing protocol procedures', 'Incoming protocol procedures', and 'Maintenance protocol procedures'.](54a1e5d91d7f442361767b1f8c81c777_img.jpg)

+
+The outgoing protocol procedures provide the mechanism to initiate an AAL type 2 connection request. The incoming protocol procedures are applied when a request for an AAL type 2 connection is received from a peer entity. Both of these procedures provide for the orderly release of an AAL type 2 connection. The maintenance protocol procedures provide the mechanisms to align the status of the AAL type 2 resources within the two adjacent AAL type 2 nodes and procedures to block and unblock an AAL type 2 path.
+
+The unrecognized information procedures in the nodal function as well as in the protocol entities provide the forward compatibility mechanism which enables extension of the protocol in the future.
+
+The nodal function keeps track of the AAL type 2 path resources.

+
+- For 7.3.3 "Destination E.164 service endpoint address" and 7.3.4 "Destination NSAP service endpoint address" which are not applicable.
+
+### **A.7.4 Field specification of the AAL type 2 signalling protocol parameters**
+
+Applicable fields are specified in 7.4/Q.2630.1 [15] except:
+
+- a) In 7.4.12/Q.2630.1 [15] add the following sentence: "Optionally, it is possible to increase the CPS-SDU size to 64 octets".
+- b) Subclauses 7.4.13/Q.2630.1, 7.4.14/Q.2630.1 and 7.4.15/Q.2630.1 are not applicable.
+- c) In 7.4.16/Q.2630.1 [15], cause "Unallocated (unassigned) number" is not applicable.
+
+## **A.8 Procedure of the AAL type 2 signalling protocol**
+
+Before an ATM VCC (AAL type 2 path) is put into service between a pair of adjacent AAL type 2 nodes, certain actions need to be performed. An identifier called the AAL type 2 path identifier is assigned to the ATM VCC. This identifier is used to refer to the ATM VCC in the AAL type 2 signalling protocol messages. The AAL type 2 path identifier shall uniquely identify the ATM VCC between the two adjacent AAL type 2 nodes.
+
+On any ATM VCC used for AAL type 2 connections, all CID values from "8" to "255" are available for assignment.
+
+Any time a new ATM VCC is put into service, the ownership of the ATM VCC shall be determined before AAL type 2 connections are established in it. In case of switched ATM VCC, the owner of the VCC shall be the AAL type 2 node that initiated the establishment of the VCC. In case of PVC and soft PVC, it is the responsibility of the management system to determine the owner of the VCC.
+
+The nodal function is informed by layer management of a newly established AAL type 2 path by the use of the ADD-PATH.indication primitive containing the adjacent AAL type 2 node identifier, the AAL type 2 path identifier, and the ownership. The nodal function is informed by layer management of the removal of an AAL type 2 path by use of the REMOVE-PATH.indication primitive containing the adjacent AAL type 2 node identifier and the AAL type 2 path identifier.
+
+In order to minimize the likelihood of CID collision, the following CID allocation mechanism shall be used:
+
+- if the AAL type 2 node owns the AAL type 2 path that carries the new connection, it allocates CID values from CID value 8 upwards; and
+- if the AAL type 2 node does not own the AAL type 2 path that carries the new connection, it allocates CID values from CID value 255 downwards.
+
+NOTE – Causes in the procedures defined in clause 8/Q.2630.1 [15] specify which ITU-T standardized code should be used in cause parameters of AAL type 2 signalling protocol messages. Implementation dependent non-standardized causes may be used for AAL type 2 signalling entity internal processing and for A2SU-SAP and LM-SAP cause primitive parameters.
+
+The service endpoint address, the served user generated reference, the served user transport parameter, the link characteristics, the SSCS information, and the test connection indicator shall not be modified by the nodal function. The served user generated reference and the served user transport are parameters with significance to the served user only; therefore, they shall not be examined by the nodal function.
+
+### **A.8.1 Compatibility**
+
+Clause 8.1 applies with the following modifications:
+
+- a) In 8.1.1/Q.2630.1 [15] "General requirements on receipt of unrecognized signalling information", bullet item d) and the Note below it are not applicable.
+
+- b) In 8.1.2.1/Q.2630.1 [15] "Unrecognized messages", the bullet item "transfer the message transparently" is not applicable.
+- c) In 8.1.2.2/Q.2630.1 [15] "Unrecognized parameters", the bullet item "transfer the parameter transparently" appears twice and is not applicable in either location.
+
+### **A.8.2 Nodal functions**
+
+#### **A.8.2.1 Nodal functions for AAL type 2 nodes with served user interaction**
+
+Clause 8.2.1/Q.2630.1 [15] applies with the modifications below.
+
+- a) Subclause 8.2.1.1.1.1/Q.2630.1 "Actions at the originating AAL type 2 service endpoint" is replaced by the following paragraphs:
+
+When the nodal function receives an ESTABLISH.request primitive from the AAL type 2 served user, it determines the availability of a route with enough AAL type 2 path resources and selects an AAL type 2 path to the succeeding AAL type 2 service endpoint.
+
+Selection of an AAL type 2 path typically is based on:
+
+- the test connection indicator;
+- link information (link characteristics); and
+- other information (such as SSCS information).
+
+AAL type 2 node internal resources are allocated for the new connection from the originating AAL type 2 served user to the outgoing AAL type 2 path.
+
+On the selected outgoing AAL type 2 path, the CID and other resources (e.g. indicated by link characteristic or SSCS information) are allocated for the outgoing AAL type 2 link.
+
+An outgoing protocol entity instance is invoked and the following parameters are passed to it: the AAL type 2 Path Identifier, and a CID value. The nodal function shall pass the following parameters to the outgoing protocol entity instance only if they were conveyed by the originating AAL type 2 served user: the link characteristics, the SSCS information, the served user generated reference, the served user transport, and the test connection indicator.
+
+NOTE 1 – Through-connection at AAL type 2 service endpoints is not specified by this Recommendation. It may be controlled by the AAL type 2 served user.
+
+After receiving an indication of the successful AAL type 2 connection setup from the outgoing protocol entity instance, an ESTABLISH.confirm primitive is sent to the AAL type 2 served user.
+
+- b) Subclause 8.2.1.1.1.2/Q.2630.1 "Actions at the destination AAL type 2 service endpoint" is replaced by the following paragraphs:
+
+Upon receiving an indication from an incoming protocol entity instance requesting a new connection, the nodal function checks the availability of the CID value and other resources, e.g., indicated by link characteristic or SSCS information in the incoming AAL type 2 path.
+
+If the test connection indicator parameter is present, a "locally blocked" or "remotely blocked" AAL type 2 path shall be acceptable for the incoming connection.
+
+If the CID and the other resources are available, they are allocated to the new connection.
+
+AAL type 2 node internal resources are allocated for the new connection from the incoming AAL type 2 path to the destination AAL type 2 served user.
+
+The nodal function acknowledges the successful AAL type 2 connection establishment towards the incoming protocol entity instance.
+
+An ESTABLISH.indication primitive is sent to the AAL type 2 served user to inform it of the successfully established new connection. The nodal function shall pass the following parameters to the outgoing protocol entity instance only if they were conveyed by the incoming protocol entity instance: the SSCS information, the served user transport, the served user generated reference, and the test connection indicator.
+
+NOTE 2 – Through-connection at AAL type 2 service endpoints is not specified by this Recommendation. It may be controlled by the AAL type 2 served user.
+
+- c) Subclause 8.2.1.1.2.1/Q.2630.1 "Actions at the originating AAL type 2 service endpoint" is replaced by the following paragraphs:
+
+If the AAL type 2 path selection or the CID and other resources allocation described in 8.2.1.1.1.1 fails, a RELEASE.confirm primitive is returned to the AAL type 2 served user with one of the following causes:
+
+- "No route to destination";
+- "No circuit/channel available";
+- "Resource unavailable, unspecified";
+- "Network out of order"; or
+- "Temporary failure".
+
+If AAL type 2 node internal resources are not available for the new connection, a RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause "Switching equipment congestion".
+
+Upon receiving a negative acknowledgement for the connection setup request from the outgoing protocol entity instance, all the resources associated with this AAL type 2 link are released and made available for new traffic. The association to the outgoing protocol entity instance is released. Features that enable a further connection attempt, involving the selection of a different AAL type 2 path within the same route, may be implemented. If no further connection attempt is made, the AAL type 2 node internal resources are released and a RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause received from the outgoing protocol entity instance.
+
+Upon receiving an indication from the outgoing protocol entity instance that a timer has expired, the association to the outgoing protocol entity instance is released and a reset procedure is started (see 8.2.1.2.1.1 case 3 a). The AAL type 2 node internal resources are released. A RELEASE.confirm primitive is sent to the AAL type 2 served user with the cause received from the outgoing protocol entity instance, i.e., "Recovery on timer expiry".
+
+#### **A.8.2.2 Nodal functions for AAL type 2 nodes without served user interaction**
+
+Subclause 8.2.2/Q.2630.1 [15] is not applicable.
+
+### **A.8.3 Protocol entity**
+
+Subclause 8.3/Q.2630.1 [15] applies.
+
+### **A.8.4 List of timers**
+
+Subclause 8.4/Q.2630.1 [15] applies.

+# Annex C
+
+# Interworking with CS-1 and CS-2 nodes for connection resource allocation
+
+Examples of interworking cases are illustrated in Appendix III.
+
+## C.1 Connection resources indicated with link characteristic parameters
+
+### C.1.1 Connection establishment
+
+#### C.1.1.1 Introduction
+
+NOTE 1 – In order to ensure interworking the following three cases are considered:
+
+- a) If no connection resource modifications are required for the AAL type 2 connection, the originating AAL type 2 served user may include a Link Characteristics parameter in the ESTABLISH.request primitive that corresponds to the Transfer Capability parameter.
+- b) If connection resource modifications may be required for the AAL type 2 connection and interworking to CS-1 nodes is not required, the originating AAL type 2 served user may include a Link Characteristics parameter and a Modify Support for Link Characteristics parameter in the ESTABLISH.request primitive; the Link Characteristics parameter corresponds to the Transfer Capability parameter.
+- c) If connection resource modifications may be required for the AAL type 2 connection and interworking to CS-1 nodes may be required, the originating AAL type 2 served user may additionally include the following parameters in the ESTABLISH.request primitive:
+  - the Link Characteristics;
+  - the Preferred Transfer Capability;
+  - the Preferred Link Characteristics; and
+  - the Modify Support for Link Characteristics.
+
+Interworking with CS-2 and CS-1 nodes is designed such that:
+
+- If the Modify Support for Link Characteristics parameter is received by the destination AAL type 2 service endpoint, no CS-1 node is part of the AAL type 2 connection; resource allocation for the AAL type 2 connection is based on the Preferred Transfer Capability (for CS-3 nodes) and Preferred Link Characteristics (for CS-2 nodes) and the connection resources are modifiable.
+- If the Modify Support for Link Characteristics parameter is not received by the destination AAL type 2 service endpoint, a CS-1 node is part of the AAL type 2 connection; resource allocation for the AAL type 2 connection is based on the Transfer Capability (for CS-3 nodes) and Link Characteristics (for CS-1 and CS-2 nodes) and the connection resources are not modifiable.
+- In all cases, the originating AAL type 2 served user includes a Transfer Capability Support parameter in the ESTABLISH.request primitive as well. If this parameter is received by a destination CS-3 service endpoint, it is sent back towards the originating AAL type 2 service endpoint. The complete AAL type 2 connection passes through CS-3 nodes only and the originating and the destination AAL type 2 served users know that the full functionality of this Recommendation is available for this connection.
+
+NOTE 2 – From the point of view of this Recommendation, it is regarded to be within the responsibility of the AAL type 2 served user to ensure consistency between Transfer Capability and Link Characteristics parameters.
+
+#### C.1.1.2 Actions at the originating AAL type 2 service endpoint
+
+In addition to the specifications in 8.2, the following applies:
+
+When the nodal function receives an ESTABLISH.request primitive from the AAL type 2 served user, the following restrictions on the optionality of the parameters of the primitive apply:
+
+- The Transfer Capability Support parameter shall be present;
+- The Link Characteristics parameter shall be present;
+- The Modify Support for Link Characteristics parameter may be present;
+- The Preferred Link Characteristics parameter may be present only if the Modify Support for Link Characteristics parameter is also present;
+- The Preferred Transfer Capability parameter shall be present if the AAL type 2 Preferred Link Characteristics parameter is present; and
+- If a Preferred Transfer Capability parameter is specified, it must refer to the same AAL type 2 transfer capability as the Transfer Capability parameter.
+
+NOTE 1 – For example, if the Transfer Capability parameter indicates a Variable Bandwidth Stringent Transfer Capability, the Preferred Transfer Capability parameter, if present, may only indicate a Variable Bandwidth Stringent Transfer Capability.
+
+Depending on the presence of Preferred Transfer Capability parameter, the following applies:
+
+- If the Preferred Transfer Capability parameter is not present, connection admission control and connection resource allocation are performed as defined in 8.2.
+- If the Preferred Transfer Capability parameter is present, the connection admission control and connection resource allocation shall be based on the most demanding of the Preferred Transfer Capability and the Transfer Capability.
+

+## **C.2 Connection resources indicated with service specific information parameters**
+
+### **C.2.1 Connection establishment**
+
+#### **C.2.1.1 Introduction**
+
+NOTE 1 – In order to ensure interworking the following three cases are considered:
+
+- a) If no connection resource modifications are required for the AAL type 2 connection, the originating AAL type 2 served user may include an SSCS Information parameter in the ESTABLISH.request primitive whose connection resource requirements corresponds to those of the Transfer Capability parameter.
+- b) If connection resource modifications may be required for the AAL type 2 connection and interworking with CS-1 nodes is not required, the originating AAL type 2 served user may include an SSCS Information parameter and a Modify Support for SSCS Information parameter in the ESTABLISH.request primitive; the connection resource requirements of the SSCS Information parameter corresponds to those of the Transfer Capability parameter.
+- c) If connection resource modifications may be required for the AAL type 2 connection and interworking to CS-1 nodes may be required, the originating AAL type 2 served user may additionally include the following parameters in the ESTABLISH.request primitive:
+  - the SSCS Information;
+  - the Preferred Transfer Capability;
+  - the Preferred SSCS Information; and
+  - the Modify Support for SSCS Information.
+
+Interworking with CS-2 and CS-1 nodes is designed such that:
+
+- If the Modify Support for SSCS Information parameter is received by the destination AAL type 2 service endpoint, no CS-1 node is part of the AAL type 2 connection; resource allocation for the AAL type 2 connection is based on the Preferred Transfer Capability (for CS-3 nodes) and Preferred SSCS Information (for CS-2 nodes) and the connection resources are modifiable.
+- If the Modify Support for SSCS Information parameter is not received by the destination AAL type 2 service endpoint, a CS-1 node is part of the AAL type 2 connection; resource allocation for the AAL type 2 connection is based on the Transfer Capability (for CS-3 nodes) and SSCS Information (for CS-1 and CS-2 nodes) and the connection resources are not modifiable.
+- In all cases, the originating AAL type 2 served user includes a Transfer Capability Support parameter in the ESTABLISH.request primitive as well. If this parameter is received by a destination CS-3 service endpoint, it is sent back towards the originating AAL type 2 service endpoint. The complete AAL type 2 connection passes through CS-3 nodes only and the originating and the destination AAL type 2 served users know that the full functionality of this Recommendation is available for this connection.

+
+The diagram illustrates the message sequences for a successful AAL type 2 connection establishment and release between two AAL type 2 service endpoints and an AAL type 2 switch.
+
+**Establishment Phase:**
+
+- The left AAL type 2 service endpoint sends an **ERQ(DSAID = 0, OSAID = r, ...)** message to the switch.
+- The switch responds with **ECF(DSAID = r, OSAID = u, ...)**.
+- The left endpoint then sends a **Memorize DSAID = u** message.
+- The switch allocates an OSAID **s** and sends an **ERQ(DSAID = 0, OSAID = s, ...)** message to the right endpoint.
+- The right endpoint responds with **ECF(DSAID = s, OSAID = t, ...)**.
+- The right endpoint then sends a **Memorize DSAID = s** message.
+- A horizontal grey bar indicates that the **AAL type 2 connection is established**.
+
+**Release Phase:**
+
+- The left endpoint sends a **REL(DSAID = u, ...)** message to the switch.
+- The switch responds with **RLC(DSAID = r, ...)**.
+- The left endpoint then sends an **Allocate OSAID = r** message.
+- The switch releases the OSAID **s** and sends a **REL(DSAID = t, ...)** message to the right endpoint.
+- The right endpoint responds with **RLC(DSAID = s, ...)**.

+
+**Figure I.1/Q.2630.3 – Example of successful AAL type 2 connection establishment and release message sequences**
+
+Signalling Association Identifiers (SAID) are treated in the following way:
+
+- 1) Whenever a new link associated signalling relationship is created, a new protocol entity instance is created and an OSAID is allocated to it; this ID is then transported in the first message in the OSAID parameter. The DSAID in this message contains the value "unknown", i.e., all octets are set to "0". (In the figures, this is indicated by "DSAID = 0".)
+- 2) Upon receipt of a message that has a DSAID field set to "unknown", a new protocol entity instance is created and an OSAID is allocated to it.
+- 3) In the first message returned to the originator of the association, the OSAID of the sending protocol entity instance is transported in the OSAID parameter. The DSAID field carries the previously received OSAID of the originator of the association.
+- 4) In all subsequent messages, the DSAID field carries the previously received OSAID of the destination entity.
+
+- 5) If the first message returned to the originator of the association is also the last one for this link associated signalling relationship (see Figure I.2 or I.3), no OSAID parameter is carried in the message. The DSAID field carries the previously received OSAID of the originator of the association.

+
+The diagram illustrates the message sequence for an unsuccessful AAL type 2 connection establishment between two AAL type 2 service endpoints and an AAL type 2 switch.
+
+- Left Service Endpoint:** Initiates the process with "Allocate OSAID = r". It sends an **ERQ(DSAID = 0, OSAID = r, ...)** message to the switch.
+- Switch:** Responds with "Allocate OSAID = u" and "Memorize DSAID = r". It then sends an **ERQ(DSAID = 0, OSAID = s, ...)** message to the right service endpoint.
+- Right Service Endpoint:** Responds with "Allocate OSAID = t", "Memorize DSAID = s", and "Release OSAID = t". It sends an **RLC(DSAID = s, ...)** message back to the switch.
+- Switch:** Receives the RLC message and sends a "Release OSAID = u" message back to the left service endpoint.
+- Left Service Endpoint:** Receives the RLC message and sends a "Release OSAID = r" message.

+## Appendix II
+
+## Conversion of CS-1 or CS-2 (Preferred) Link Characteristics to (Preferred) Transfer Capability parameters
+
+The purpose of this appendix is to give guidance to implementers how to capture the problem of interworking of CS-1 and CS-2 Link Characteristics parameters into CS-3 Transfer Capability parameters.
+
+NOTE – In this Appendix the terms "Transfer Capability" and "Preferred Transfer Capability" and the abbreviations "TC" and "PTC" do not distinguish between the different types of Transfer Capabilities, i.e., Fixed Bandwidth, Variable Bandwidth Stringent, Variable Bandwidth Tolerant.
+
+### **II.1 Guidelines and definitions**
+
+This appendix provides rules for conversions from LC-type to TC-type parameters. In some cases, explicit expressions are defined that allow computing the outgoing parameter values based on incoming parameter values. These expressions should be understood as formal in the sense that:
+
+- they do not request by themselves the existence of certain parameters neither incoming nor outgoing,
+- they do not overrule constraints of any type that are defined within this protocol specification.
+
+For the purpose of this clause, the following shorthand notation shall be used (see Tables II.1 to II.4).

+CPHL shall denote the length of the CPS packet header (see ITU-T Rec. I.363.2 [1]) in octet.
+
+For any real number  $x$ ,  $[x]$  is defined as the smallest integer greater or equal to  $x$ .
+
+MAX ( $x_1, \dots, x_n$ ) determines the maximum, MIN ( $x_1, \dots, x_n$ ) the minimum of the values  $x_1, \dots, x_n$ .
+
+Bit rates are measured in bit per second ("bit/s"), sizes, e.g., of data structures, in octet.
+
+### II.2 Bit rates
+
+The conversion from LC-type to TC-type bit rates requires to estimate the rate that will be caused by the CPS packet header overhead of length CPHL. This estimate is given in Table II.5. The values are "normalized" to multiples of 64 bit/s.

+### II.4 Token bucket sizes
+
+The CS-3 node receiving LC without TC in an initial ERQ shall set the token bucket sizes to the allowed maximum values. The allowed maximum value is the minimum out of the maximum defined by the protocol and the maximum defined within the network.
+
+NOTE – If modification is possible, an appropriate adjustment of the token bucket sizes controlled by the Served User may be initiated from a CS-3 service endpoint with a subsequent MOD message.
+
+Token bucket sizes shall not be affected by received MOD messages with LC but without TC parameter.
+
+### II.5 Determination of the TC class
+
+ITU-T Rec. I.378 [19] defines three AAL Type 2 transfer capability classes: Fixed Bandwidth, Variable Bandwidth Stringent, and Variable Bandwidth Tolerant Transfer Capability.
+
+A CS-3 node receiving LC without TC in an initial ERQ has to determine the AAL Type 2 Transfer Capability class to be used by CS-3 nodes.
+
+If all subsequent conditions:
+
+- C1) A = B
+- C2) C = D
+- C3) E = F
+- C4) G = H
+- C5) MSLC not set
+
+are satisfied, the Fixed Bandwidth Transfer Capability shall be selected. If at least one of the conditions C1), ... , C5) is not fulfilled, the Variable Bandwidth Stringent or Variable Bandwidth Tolerant Transfer Capability shall be applied. If not otherwise indicated by administrative settings in the CS-3 node (possibly in dependence from a received Path Type parameter), Variable Bandwidth Stringent Transfer Capability shall be selected.
+
+### II.6 Source traffic type
+
+A CS-3 node, which receives LC (and possibly PLC) without TC (and PTC) in an initial ERQ and which selects the Variable Bandwidth Stringent Transfer Capability, shall set the Source Traffic Type parameters in TC (and possibly PTC) as follows:
+
+STT = STT unknown
+
+stt = STT unknown
+
+NOTE 1 – If the received signalling information or network configuration knowledge indicate that other valid source traffic type values are more suitable, then the STT and stt parameters may be set to values other than "unknown".
+
+NOTE 2 – If modification is possible, an appropriate adjustment of the source traffic type controlled by the Served User may be initiated from a CS-3 service endpoint with a subsequent MOD message.
+
+Source traffic types shall not be affected by received MOD messages with LC but without TC parameter.
+
+## Appendix III
+
+## Interworking examples
+
+This appendix illustrates the mechanism for connection resource allocation in a network where the CS-1 and CS-2 nodes allocate connection resources based on link characteristics. The mechanisms where CS-1 and CS-2 nodes allocate connection resources based on SSCS information are similar.
+
+This appendix assumes the behaviour of CS-3 nodes according to Annex C.
+
+### III.1 Symbols and abbreviations
+
+The diagrams show the exchange of ERQ/ECF messages (originating at left) and the exchange of MOD/MOA messages (also originating at left). Only parameters relevant to connection resource reservation and allocation are shown.
+
+- a) The 1st column shows the name of the relevant parameters.
+
+On the Modify Request (MOD) message, LC<sub>old</sub> indicates the actually allocated resources in CS-2 and CS-1 nodes, LC<sub>new</sub> the new LC that the modification attempts to allocate. Similarly, TC<sub>old</sub> indicates the actually allocated resources in CS-3 nodes, TC<sub>new</sub> the new TC that the modification attempts to allocate.
+
+NOTE – The indications TC, PTC, LC, and PLC in the 1st column of the ECF messages or the indications TC<sub>old</sub>; TC<sub>new</sub>; LC<sub>old</sub>; and LC<sub>new</sub> in the 1st column of the MOA messages do not refer to parameters carried in the message but are used to indicate which parameter is used to make the actual resource allocation.
+
+- b) The 2nd column shows the name of the message.  
+c) The 3rd column indicates the parameters of the primitive from (↪) or to (↩) the originating served user.  
+d) The 4th to the 13th columns show the AAL type 2 nodes where in the top cell the capability set of the node is indicated. The indications in the other cells are explained below.  
+e) The 14th column indicates the parameters of the primitive to (↩) or from (↪) the destination served user.
+
+In columns 4 to 13, the indications in a row of a parameter or an actually allocated resource have the following meaning:
+
+- "-": Parameter not present or actual resource allocation not done with this parameter.  
+"—": Parameter passed because it is not relevant or due to the compatibility instructions.  
+"==": Parameter passed according to specifications in ITU-T Recs Q.2630.1 [15] or Q.2630.2 [16].  
+"≡": Parameter passed according to instructions in 8.2.  
+"✓": Parameter processed.  
+"A": This parameter is used to perform the allocation of resources.  
+"R": These parameters are used to reserve resources according to the "most demanding" requirements.  
+"★": Parameter inserted by the AAL type 2 node.  
+"✗": Parameter discarded by the AAL type 2 node due to compatibility instructions.  
+"⊠": Parameter discarded by the AAL type 2 node due interworking specifications instructions (see Annex C).
+
+### III.2 Connection Establishment

+Figure III.1/Q.2630.3 – All CS-3 nodes in the AAL type 2 connection

+In the ESTABLISH.request primitive, the nodal function receives from the AAL type 2 served user the following parameters relevant to interworking and connection resource allocation:
+
+- the Transfer Capability;
+- the Preferred Transfer Capability;
+- the Transfer Capability Support;
+- the Link Characteristics;
+- the Preferred Link Characteristics; and
+- the Modify Support for Link Characteristics.
+
+Nodes CS3a, CS3b, CS3c, CS3d, CS3e, CS3f, CS3g, and CS3h reserve connection resources reflecting the more "demanding" of the parameters Transfer Capability (TC) and Preferred Transfer Capability (PTC).
+
+Node CS3i allocates connection resources reflecting the Preferred Transfer Capability (PTC) parameter; this decision is based on the presence of the Preferred Transfer Capability (PTC) parameter. The parameters Transfer Capability (TC), Preferred Transfer Capability (PTC), Link Characteristics (LC), Preferred Link Characteristics (PLC), Modify Support for Link Characteristics (MSLC), and Transfer Capability Support (TCS) are passed to the AAL type 2 served user, which interprets the last parameter to indicate that the AAL type 2 connection passes only through CS-3 nodes and that, therefore, the full functionality of this Recommendation is available.
+
+The parameters Modify Support for Link Characteristics (MSLC) and Transfer Capability Support (TCS) are inserted into the Establish Confirm (ECF) message.
+
+Nodes CS3h, CS3g, CS3f, CS3e, CS3d, CS3c, CS3b, and CS3a allocate connection resources reflecting the Preferred Transfer Capability (PTC) parameter that was passed previously in the Establish Request (ERQ) message or received from the AAL type 2 served user; this decision is based on the presence of the Modify Support for Link Characteristics (MSLC) parameter in the Establish Confirm (ECF) message.
+
+Node CS3a includes the Modify Support for Link Characteristics (MSLC) and Transfer Capability Support (TCS) parameters in the ESTABLISH.confirm primitive to the AAL type 2 served user, which interprets the latter parameter to indicate that the AAL type 2 connection passes only through CS-3 nodes and that, therefore, the full functionality of this Recommendation is available.

+
+At node CS3h it is detected that although no Preferred Link Characteristics (PLC) parameter is present, a Preferred Transfer Capability (PTC) parameter is; this parameter is discarded due to interworking definitions (see Annex C) before the Establish Request (ERQ) message is interpreted by the nodal function.

The parameters Transfer Capability (TC) and Link Characteristics (LC) are passed to the AAL type 2 served user.

+In the ESTABLISH.request primitive, the nodal function receives from the AAL type 2 served user the following parameters relevant to interworking and connection resource allocation:
+
+- the Link Characteristics;
+- the Preferred Link Characteristics; and
+- the Modify Support for Link Characteristics.
+
+Nodes CS2a, CS2b, CS2c, CS2d, and CS2e reserve connection resources reflecting the more "demanding" of the parameters Link Characteristics (LC) and Preferred Link Characteristics (PLC).
+
+At node CS3f, the Transfer Capability (TC) parameter is not present; hence, the nodal function prepares a Transfer Capability (TC) parameter corresponding to the Link Characteristics (LC) parameter. In addition, the Preferred Link Characteristics (PLC) parameter is present also; hence, the nodal function prepares a Preferred Transfer Capability (PTC) parameter corresponding to the Preferred Link Characteristics (PLC) as well. Node CS3f then reserves connection resources reflecting the more "demanding" of the parameters Transfer Capability (TC) and Preferred Transfer Capability (PTC).
+

The parameters Transfer Capability (TC), Preferred Transfer Capability (PTC), Link Characteristics (LC), Preferred Link Characteristics (PLC), and Modify Support for Link Characteristics (MSLC) are passed to the AAL type 2 served user. The absence of the Transfer Capability Support (TCS) parameter indicates that the AAL type 2 connection does not pass through CS-3 nodes entirely. The Modify Support for Link Characteristics (MSLC) parameter is inserted into the Establish Confirm (ECF) message.
+
+Nodes CS3h, CS3g, and CS3f allocate connection resources reflecting the Preferred Transfer Capability (PTC) parameter that was previously passed in the Establish Request (ERQ) message; this decision is based on the presence of the Modify Support for Link Characteristics (MSLC) parameter in the Establish Confirm (ECF) message.

+Node CS3i allocates connection resources reflecting the Transfer Capability ( $TC_{new}$ ) parameter. The parameters Transfer Capability ( $TC_{new}$ ) and Link Characteristics ( $LC_{new}$ ) are passed to the AAL type 2 served user.
+
+Nodes CS3h, CS3g, and CS3f allocate connection resources reflecting the new Transfer Capability ( $TC_{new}$ ) parameter that was previously passed in the Modify Request (MOD) message; this decision is based on the nature of the message, i.e., Modification Acknowledge (MOA) message rather than the Modification Reject (MOR) message.
+
+Nodes CS2e, CS2d, CS2c, CS2b and CS2a allocate connection resources reflecting the new Link Characteristics ( $LC_{new}$ ) parameter that was previously passed in the Modify Request (MOD) message or received from the AAL type 2 served user; this decision is based on the nature of the message, i.e., Modification Acknowledge (MOA) message rather than the Modification Reject (MOR) message.
+
+Node CS2a sends a MODIFY.confirm primitive to the AAL type 2 served user.

+# **Extensions to the B-ISDN user part – Application generated identifiers**
+
+## **Summary**
+
+This Recommendation defines B-ISUP capability to transport application generated identifiers. This capability allows the transport through the B-ISDN of identifiers required and used by various distributed applications. This capability allows an originating entity (e.g. a calling party) to transmit identifiers that can be used by a peer entity.
+
+## **Source**
+
+ITU-T Recommendation Q.2726.4 was revised by ITU-T Study Group 11 (1997-2000) and approved under the WTSC Resolution 1 procedure on 15 June 2000.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+- c) *Generic identifier transport information elements (octet 2-n)*
+- This field contains all instances of the generic identifier transport information element received from DSS2 or generated by an originating or addressed entity located in the network. The format of the generic identifier transport information elements is the same as specified in ITU-T Q.2941.1 [6]. The order of the information elements is not changed. The number of instances or maximum length of the generic identifier transport information element is network-dependent.
+
+## 5.3 Application process procedures
+
+### 5.3.1 Call/connection establishment
+
+- a) *Originating exchange*
+- The Set\_Up request primitive may include an application generated identifier parameter carrying unaltered, one or more instances of the generic identifier transport information element received from the DSS2 or generated by an application entity located in the originating exchange.
+- b) *Intermediate national exchange*
+- If an incoming side of an intermediate national exchange receives an application generated identifier parameter in a Set\_Up indication primitive, the outgoing side of the exchange will include it unaltered in the Set\_Up request primitive it will issue.
+- c) *Outgoing international exchange*
+- If an outgoing international exchange receives an application generated identifier parameter in a Set\_Up indication primitive, it shall include it unaltered in the Set\_Up request primitive it will issue.
+- d) *Incoming international exchange*
+- It is a network option how an incoming international gateway shall proceed when it receives an application generated identifier parameter. If the application generated identifier service is not supported by the network, the incoming international exchange may either:
+- clear the call with cause # 63, "Service option not available, unspecified", or
+  - pass on the parameter and progress the call establishment.
+- If the incoming international gateway decides to progress the call establishment, it will issue a Set\_Up request primitive containing unaltered, the application generated identifier parameter it has received.
+
+#### e) *Destination exchange*
+
+If the Set\_Up request primitive contains an application generated identifier parameter, it will be transferred unaltered in the indication sent to the called party as specified in ITU-T Q.2941.1 [6]. Alternatively, the destination exchange may process the application generated identifier parameter, if the addressed entity is located in the destination exchange.
+
+### 5.3.2 Completion of the call/connection setup request
+
+#### a) *Destination exchange*
+
+Primitives issued by the destination exchange after receiving a signal from the called party may contain an application generated identifier parameter. The application generated identifier parameter will contain unaltered, the identifiers received from the access or generated by the addressed entity. The following primitives may carry the application generated parameter:
+
+- Address\_Complete request;
+- Progress request;
+- Answer request.
+
+#### b) *Intermediate national or international exchange*
+
+The incoming side of an intermediate national or international exchange may receive in the Address\_Complete indication, the Progress indication or the Answer indication primitive an application generated identifier parameter. The outgoing side of the exchange will pass the application generated identifier parameter in a corresponding Address\_Complete indication, Progress indication or Answer indication primitive.
+
+It is a network option how an incoming or outgoing international gateway shall proceed when it receives an application generated identifier parameter. The options defined in 5.3.1 d) are applicable.
+
+#### c) *Originating exchange*
+
+The originating exchange may receive an Address\_Complete indication, a Progress indication or an Answer indication primitive containing an application generated identifier parameter. The access side of the originating exchange will relay the contents of the application generated identifier parameter to the calling party in the appropriate access signal or to the application entity.
+
+### 5.3.3 Call/connection release
+
+#### a) *Access exchange initiating the release procedure*
+
+When the call/connection release is initiated by a user, the access exchange may receive from the user initiating the release, a signal carrying one or more application generated identifiers. The Release request primitive will carry them in an application generated identifier parameter.
+
+#### b) *Intermediate national or international exchange*
+
+If an incoming side of an intermediate exchange receives an application generated parameter in a Release indication primitive, the outgoing side of the exchange will include them unaltered in the Release request primitive to be issued.
+
+It is a network option how an incoming or outgoing international gateway shall proceed when it receives an application generated identifier parameter. The options defined in 5.3.1 d) are applicable.
+
+#### c) *Access exchange receiving a release indication*
+
+If an access exchange receives a Release indication primitive containing an application generated identifier parameter, the contents will be transferred unaltered in the indication sent to the user as specified in ITU-T Q.2941.1 [6].

+# **Soft PVC Capability**
+
+## **Summary**
+
+This Recommendation utilizes the normal procedures of Broadband ISDN User Part (B-ISUP) protocol in order to support soft Permanent Virtual Connections (soft PVCs) between their endpoints. The endpoints are responsible for maintaining the end-to-end circuit by setting up a new switched connection in case the existing switched connection is released or fails. Two types of soft PVC are supported: soft Permanent Virtual Path Connection (PVPC) and soft Permanent Virtual Channel Connection (PVCC). This Recommendation contains the additional message and parameter coding, procedures, ASE descriptions and interworking mapping tables for the support of soft PVCC and soft PVPC services.
+
+## **Source**
+
+ITU-T Recommendation Q.2767.1 was revised by ITU-T Study Group 11 (1997-2000) and approved under the WTSC Resolution 1 procedure on 15 June 2000.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+## Soft PVC capability
+
+# 1 Scope
+
+This Recommendation contains formats and procedures for supporting soft Permanent Virtual Connections (soft PVCs). Soft PVC capability utilizes the normal procedures of B-ISUP in order to control soft permanent virtual circuit connections between their endpoints. The endpoints are responsible for maintaining the end-to-end circuit by setting up a new switched connection in case the existing switched connection is released or fails.
+
+The endpoints of a soft PVC are located in the exchanges to which the users of the soft PVC are connected. The endpoint is identifiable by addressing information contained in the call setup signalling, such as an E.164 number plus VPCI/VCI or DLCI value.
+
+Figure 1 identifies different reference points in a soft PVC using internal SVC connection switching and signalling.
+
+![Diagram of Soft PVC configuration showing a User connected to a Soft PVC called endpoint, which is connected via NNI signalling to another Soft PVC called endpoint, which is then connected to another User. The connections between the endpoints are labeled VC or VP.](0236eff05bcb8f3a343ea7933aaa306b_img.jpg)
+
+The diagram illustrates a soft PVC configuration. It shows a 'User' (represented by a square) connected to a 'Soft PVC called endpoint' (represented by a circle). This endpoint is connected via an 'NNI signalling' link (represented by a curved line) to another 'Soft PVC called endpoint' (another circle). This second endpoint is connected via another 'NNI signalling' link to a third 'Soft PVC called endpoint' (a third circle), which is then connected to another 'User' (another square). The connections between the 'Soft PVC called endpoint' circles are labeled 'VC or VP'. The diagram is labeled 'T11100980-98' in the bottom right corner.

+
+Figure 1/Q.2767.1 – Soft PVC configuration
+
+Two types of soft PVC are supported:
+
+- soft permanent virtual path connection (PVPC); and
+- soft permanent virtual channel connection (PVCC).
+
+This Recommendation contains the additional message and parameter coding, procedures, ASE descriptions and interworking mapping tables for the support of soft PVCC and soft PVPC services.
+
+The procedures for control of soft PVCCs are applicable to point-to-point and point-to-multipoint procedures.
+
+The procedures for control of soft PVPCs follow the additional procedures for switched virtual path connections in ITU-T Q.2766.1.
+
+The frame relay endpoints can only be connected by a soft PVCC connection and not by a soft PVPC connection.

+If the DLCI indicator and value exist in the Soft PVC parameter then the VPCI/VCI indicator and value is not needed, i.e. the two subfield parameters are mutually exclusive and only one of the two subfields can exist at one time. Currently the soft PVC called endpoint is coded as follows.

+
+# 6 Application process procedures
+
+## 6.1 Connection setup
+
+### 6.1.1 Calling endpoint exchange
+
+The request to set up soft PVC is transmitted from the management entity to the application process and the request includes an indication whether a soft PVC is a soft PVCC or soft PVPC. If the user of the soft PVC is a Frame Relay interface only soft PVCC can be requested from the management entity.
+
+The soft PVC calling endpoint exchange shall initiate connection establishment by generating a Set\_Up request primitive to B-ISUP, containing the Soft PVC called endpoint parameter. The Called
+
+Party Number shall contain the address corresponding to the soft PVC called endpoint. The Calling Party Number shall contain the address corresponding to the soft PVC calling endpoint.
+
+The use of soft PVC procedures is indicated by the inclusion of the Soft PVC called endpoint parameter.
+
+If the VPCI/VCI or DLCI at the destination must be conveyed to the soft PVC called endpoint exchange, then this information is also carried in the Soft PVC called endpoint parameter. In this case, the selection type field should be set to "required value" and the Soft PVC called endpoint parameter shall indicate the VPCI value in case of setup of a soft PVPC or the VPCI/VCI or DLCI value in case of setup of a soft PVCC, respectively.
+
+In the case where the VPCI/VCI or DLCI shall be determined by the soft PVC called endpoint exchange, the Soft PVC called endpoint parameter shall be included with the selection type set to "any value". In this case, neither VPCI/VCI nor DLCI shall be indicated.
+
+The Soft PVC calling endpoint parameter may be included on an optional basis.
+
+For a soft PVCC call, the normal procedures in ITU-T Q.2764 are used. For a soft PVPC call, the procedures in ITU-T Q.2766.1 are used.
+
+### **6.1.2 Intermediate national exchange**
+
+For a soft PVCC call, the intermediate national exchange shall use the normal procedures as in ITU-T Q.2764 in order to set up the connection. For a soft PVPC call, the intermediate national exchange shall use the procedures in ITU-T Q.2766.1 to set up the connection. The presence of the Soft PVC called endpoint parameter indicates that the call is supporting the soft PVC capability.
+
+### **6.1.3 Outgoing international exchange**
+
+For a soft PVCC call, the outgoing international exchange shall use the normal procedures as in Q.2764 in order to set up the connection. For a soft PVPC call, the outgoing international exchange shall use the procedures in Q.2766.1 to set up the connection. The presence of the Soft PVC called endpoint parameter indicates that the call is supporting the soft PVC capability.
+
+### **6.1.4 Intermediate international exchange**
+
+For a soft PVCC call, the intermediate international exchange shall use the normal procedures as in Q.2764 in order to set up the connection. For a soft PVPC call, the intermediate international exchange shall use the procedures in Q.2766.1 to set up the connection. The presence of the Soft PVC called endpoint parameter indicates that the call is supporting the soft PVC capability.
+
+If the soft PVC capability is not supported by the receiving network, the call shall be cleared with Cause No. 21 "call rejected".
+
+### **6.1.5 Incoming international exchange**
+
+For a soft PVCC call, the incoming international exchange shall use the normal procedures as in ITU-T Q.2764 in order to set up the connection. For a soft PVPC call, the incoming international exchange shall use the procedures in ITU-T Q.2766.1 to set up the connection. The presence of the Soft PVC called endpoint parameter indicates that the call is supporting the soft PVC capability.
+
+If the soft PVC capability is not supported by the receiving network, the call shall be cleared with Cause No. 21 "call rejected".
+
+### **6.1.6 Called endpoint exchange**
+
+The soft PVC called endpoint exchange shall terminate call setup without sending an indication to the user, since no signalling is required for the connection segment between the endpoint and user.
+
+If the selection type in the Soft PVC called endpoint parameter is set to "any value", the soft PVC called endpoint exchange shall select a pre-determined VPCI/VCI or DLCI. If the selection type in the Soft PVC called endpoint parameter is set to "required value", the VPCI/VCI or DLCI indicated in the Soft PVC called endpoint parameter is used to associate the call with a particular connection segment at the soft PVC called endpoint.
+
+The soft PVC called endpoint exchange shall verify the authorization for the call based on the Calling Party Number, the Called Party Number and the Soft PVC called endpoint parameter. If the information is not correct, the call shall be cleared with Cause No. 21 "call rejected".
+
+If the call type is incompatible with the terminating access (e.g. call setup for a soft PVPC attempting to connect to a soft PVCC access link), then the call shall be cleared with Cause No. 21 "call rejected".
+
+If the selection type in the Soft PVC called endpoint parameter is set to "any value" and the VPCI/VCI or DLCI is included, the call shall be cleared with Cause No. 111 "Protocol error, unspecified".
+
+If the VPCI/VCI (or DLCI) in the case of PVCC or VPCI in the case of PVPC is not available at the terminating access, the call shall be cleared with Cause No. 34 "No circuit/channel available".
+
+## **6.2 Answer**
+
+### **6.2.1 Called endpoint exchange**
+
+Upon successful completion of call setup of the soft PVC, the soft PVC called endpoint exchange shall send the Answer request primitive back towards the soft PVC calling endpoint exchange. The Soft PVC called endpoint parameter shall be included in the Answer request primitive, with the indication of the VPCI in case of soft PVPC setup or VPCI/VCI (or DLCI) in case of soft PVCC setup, respectively, used at the soft PVC called endpoint. The selection type field shall be set to "assigned value".
+
+### **6.2.2 Calling endpoint exchange**
+
+Upon receiving the Answer indication primitive, the soft PVC calling endpoint exchange shall send an indication to management process.
+
+If the selection type in the Soft PVC called endpoint parameter is not set to "assigned value", then the call shall be cleared with Cause No. 111 "Protocol error, unspecified".
+
+### **6.2.3 Other types of exchanges**
+
+The procedures of ITU-T Q.2764 or Q.2766.1 apply.
+
+## **6.3 Unsuccessful connection setup**
+
+### **6.3.1 Calling endpoint exchange**
+
+The procedures of ITU-T Q.2764 or Q.2766.1 for the originating exchange apply with the following additions:
+
+If all attempts to reroute the connection fail, the exchange shall follow the procedures as described in 6.5.1.
+
+### **6.3.2 Other type of exchanges**
+
+The procedures of ITU-T Q.2764 or Q.2766.1 apply.
+
+## 6.4 Storage of call setup information
+
+The soft PVC calling endpoint exchange shall store the information of the IAM for as long as the soft PVCC or soft PVPC is offered to the customer. This allows re-establishment of the connection after failure.
+
+## 6.5 Release
+
+### 6.5.1 Release within the network
+
+In case of failure, the connection may be released by the detecting node in accordance with the procedures of ITU-T Q.2764 or Q.2766.1, as appropriate.
+
+Upon receipt of a first Release indication primitive (or Incoming Resources Rejected indication primitive), the soft PVC calling endpoint exchange shall send an indication to the management process, and depending on the cause value, may attempt to re-establish the connection immediately by using the call setup procedures as defined in 6.1 above.
+
+Upon receipt of the subsequent Release indication primitive (or Incoming Resources Rejected indication primitive), and if the maximum number of retries has not been reached, the exchange may, depending on the cause value, start the timer "Wait for Retry". The maximum number of retries is determined specifically for that soft PVC by the operator. If the maximum number of retries has been reached and the connection is not re-established or a specific cause value to stop the re-establishment is received, the exchange shall send another indication to the management process.
+
+When the timer "Wait for Retry" expires, the exchange shall attempt to re-establish the connection by using the call setup procedures defined in 6.1 above.
+
+### 6.5.2 Release by the calling endpoint exchange
+
+The soft PVC calling endpoint exchange may release the connection, based on a request from the management process. At this point, the calling endpoint exchange may release all information associated with the call.

+## 7.3 ASE descriptions
+
+No changes are required to the ASE descriptions for BCC or CC ASEs.
+
+# 8 Instruction indicators and interworking
+
+## 8.1 Interworking with nodes not supporting this feature
+
+The instruction indicators shall be set so as to cause the call to be released at endpoint and gateway exchanges, but passed through transit exchanges. The instruction indicators for the Soft PVC called endpoint parameter, as shown in Appendix I, shall be set to be passed through transit exchanges, and to cause release if pass on is not possible.
+
+As a network option, the instruction indicators for the Soft PVC called endpoint parameter can be set to be released at transit exchanges.
+
+## **8.2 Interworking with DSS2**
+
+There is no interworking with DSS2, since there is no signalling required for the connection segment between the endpoint and user.
+
+## **8.3 Interworking with narrow-band ISDN**
+
+There is no interworking with narrow-band ISDN, since soft PVC is not supported in narrow-band. The Soft PVC called endpoint parameter shall be set to cause release at the broadband/narrow-band interworking point.
+
+The instruction indicators for the Soft PVC called endpoint parameter shall be coded as shown in Appendix I.
+
+As a network option, the instruction indicators for the Soft PVC called endpoint parameter can be set to be released at transit exchanges.

+
+### **8.4.9 Frame relay**
+
+A Frame Relay user of the soft PVCC is supported in this Recommendation. The interworking of a Frame Relay network with the soft PVC is for further study.
+
+## **8.5 Interworking with the first release of soft PVC – ITU-T Q.2767.1 (05/98)**
+
+If the information (i.e. the DLCI) is not recognized by the terminating exchange, the call shall be treated according to the procedure specified in ITU-T Q.2764 for unrecognized information parameter.
+
+If the call type is incompatible with the terminating access (e.g. call setup for a FR endpoint to connect to an ATM device), then the call shall be cleared with Cause No. 21 "call rejected". This should not occur under normal conditions and therefore can only occur under error conditions.

+
+## Retry decision
+
+A different decision may be required, if the failure is during:
+
+- *activation*
+  - the soft PVC was not active before, so a configuration error is quite possible;
+  - the operator is waiting for an answer: if the problem is no configuration error after all, or if the operator wants to retry anyway, the operator can do the retry; or
+- *re-establishment*
+  - the soft PVC was active before, so a configuration error is not likely (but possible);
+  - the operator is not "handling" the soft PVC, so the node should retry.
+
+Taking this into account, the following guidelines can be established to decide on a retry during:
+
+- *activation*
+
+Retry if:
+
+  - unexpected cause value (→assume that this is caused by a temporary failure);
+  - cause indicates a temporary failure.
+
+Do **not** retry if:
+
+  - cause possibly indicates a configuration problem;
+  - cause indicates a "long term" failure.
+- *re-establishment*
+
+Retry if:
+
+  - unexpected cause (→assume that this is caused by a temporary failure);
+  - cause indicates a temporary failure;
+  - cause *possibly* indicates a configuration problem.
+
+Do **not** retry if:
+
+  - cause *certainly* indicates a configuration error;
+  - cause indicates a "long term" failure.
+
+For all undefined (reserved) cause values, the action is according to the "Unspecified" value within the class. See Table II.1.

+## **ITU-T RECOMMENDATION Q.2932.1**
+
+# **DIGITAL SUBSCRIBER SIGNALLING SYSTEM NO. 2 – GENERIC FUNCTIONAL PROTOCOL: CORE FUNCTIONS**
+
+## **Summary**
+
+This Recommendation defines the operation of the Digital Subscriber Signalling System Number 2 (DSS 2) for Generic Functional Protocol core functions at the  $T_B$  or at the coincident  $S_B$  and  $T_B$  reference point of the User to Network Interface of the Broadband-Integrated Services Digital Network (B-ISDN). The Generic Functional Protocol core functions defined in this Recommendation provide a means of exchanging ROSE components on behalf of signalling application in peer entities. These signalling applications may either be for the support of supplementary services or provide protocol support for the other features (such as Look Ahead, Status request, Local/remote interrogation), in association with existing calls and bearers (bearer related signalling), or independently of existing bearers (connection-oriented or connectionless bearer independent signalling).
+
+## **Source**
+
+ITU-T Recommendation Q.2932.1 was prepared by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 9th of July 1996.
+
+# FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+# **DIGITAL SUBSCRIBER SIGNALLING SYSTEM No. 2 – GENERIC FUNCTIONAL PROTOCOL: CORE FUNCTIONS**
+
+*(Geneva, 1996)*
+
+# **1 Scope**
+
+This Recommendation specifies the functional protocol for the Broadband Integrated Services Digital Network (B-ISDN), using local information exchange, for the application to a range of additional basic call capabilities and supplementary services at the  $T_B$  reference point or coincident  $S_B$  and  $T_B$  reference point (as defined in Recommendation I.413 [1] by means of the Digital Subscriber Signalling System No. 2 (DSS 2) protocol.
+
+The functional protocol is based on the use of the Facility information element.
+
+To be functional, this protocol requires knowledge of the additional basic call capabilities and supplementary services supported by the user equipment. This facilitates user equipment operation without human intervention by defining the semantics for the protocol elements which user equipment can process on its own.
+
+The procedures specified in this Recommendation can be used for:
+
+- activation and deactivation;
+- invocation and operation;
+- interrogation;
+- status request; and
+- status notification;
+
+of additional basic call capabilities and supplementary services in association with existing calls or outside any existing call.
+
+The application of this Recommendation to individual additional basic call capabilities and supplementary services is outside the scope of this Recommendation and is defined in those Recommendations which specify the individual capabilities.
+
+Further parts of this Recommendation cover the capabilities for non-local addressing within the generic functional protocol.
+
+All conformance to this Recommendation is based on the external behaviour at the interface at the  $T_B$  or coincident  $S_B$  and  $T_B$  reference point, i.e. on the generation of the correct message structure and in the proper sequence as specified in this Recommendation.
+
+Further part(s) of this Recommendation specify the method of testing required to identify conformance to this Recommendation.
+
+This Recommendation is applicable to equipment, supporting additional basic call capabilities and supplementary services using the functional protocol, to be attached at either side of a  $T_B$  reference point or coincident  $S_B$  and  $T_B$  reference point when used as an access to the public ISDN.

+# 3 Definitions
+
+This Recommendation makes use of the following terms defined in Recommendation X.219 [3]:
+
+- remote operation;
+- operation;
+- operation classes (class 1 to class 5);
+- association (initiator; responder);
+- invoking (application entity; invoker).
+
+For the purposes of this Recommendation, the following definitions apply:
+
+**3.1 application protocol data unit (APDU); component:** Data structure as defined in A.1. The term component that appears in Recommendations defining DSS 1 has an identical meaning.
+
+**3.2 bearer-independent control message:** A message as defined in 8.1.3, which on sending or receipt causes a change of the call/connection state at either the network or the user.
+
+**3.3 bearer-related transport mechanism:** A procedure tied to the procedures for basic call control and tied to a connection in progress, active or in the clearing phase. The call reference used by the basic call control procedure is adopted by the bearer-related service invocations to correlate with the appropriate basic call control transaction.
+
+**3.4 bearer-independent transport mechanism:** A procedure independent of the procedures for basic call control and not correlated to a connection.
+
+**3.5 call/connection control message:** A message as defined in 3.1/Q.2931 [13], which on sending or receipt causes a change of the call/connection state at either the network or the user. For a call that interworks with the Narrow-band ISDN (N-ISDN), a message as defined in 3.1/Q.2931 or 3.2/Q.2931 [13] which on sending or receipt causes a change of the call/connection state at either the network or the user. In this case, call/connection control messages also include the INFORMATION message and PROGRESS message.
+
+**3.6 call reference:** (Excluding dummy call reference) an identifier of a signalling transaction. The signalling transaction may either be bearer related, in which case the signalling transaction can be used to control that bearer, or bearer independent, in which case there is no bearer associated with that signalling transaction. Where there is only one bearer required for a call, then the call reference of the associated bearer-related signalling transaction may be used to identify the call.
+
+**3.7 call/connection state:** A state as defined in 2.1/Q.2931 [13] for either the user or the network as appropriate. For a call that interworks with the N-ISDN, a state as defined in 2.1/Q.2931 or 2.2/Q.2931 [13] for either the user or the network as appropriate. A call/connection state may exist for each call reference value [and for each additional responding Connection Endpoint Identifier (CEI) in the incoming call/connection states].
+
+**3.8 call:** See 2.2/Q.9 [4], definition 2201.
+
+**3.9 connection:** See clause 0/Q.9 [4] definition 0011. In this Recommendation, the use of this term is taken to include a bearer and its associated control signalling.
+
+**3.10 connection-oriented transport mechanism:** A mechanism requiring the establishment of a signalling AAL connection and a transport association between the service requesting entity and the
+
+service provider. It provides a facility to access remote operations where success and/or failure reporting is required. It provides a call reference within the transport association as a means to associate uniquely among the related transport messages.
+
+**3.11 connectionless transport mechanism:** A mechanism where no transport association exists but a single transport message transfer is provided using the dummy call reference.
+
+**3.12 dummy call reference:** A null value indicating that the message is not applicable to an identified signalling transaction. Other rules specify the association of DSS 2 protocol entities.
+
+**3.13 functional protocol:** A functional protocol consists of a sequence of functional information elements. A functional information element requires a degree of intelligent processing by a terminal in either generation or analysis.
+
+**3.14 incoming network:** An incoming transport entity that is also a network, i.e. DSS 2 protocol entity at the network side of the interface. For bearer-related transport, the incoming network is also the destination network.
+
+**3.15 incoming transport entity:** An entity that responds to a peer entity initiating a transport mechanism.
+
+**3.16 incoming user:** An incoming transport entity that is also a user, i.e. DSS 2 protocol entity at the user side of the interface. For bearer-related transport, the incoming user is also the destination user.
+
+**3.17 initiator:** An entity (user or network) requesting establishment of a signalling connection between an initiator and the responder.
+
+**3.18 integrated Services Digital Network (ISDN):** See 2.3/I.112 [5], definition 308.
+
+**3.19 invoke APDU:** See 9.4.2.1. Where reference is made to an "xxxx" invoke APDU, an invoke APDU is meant with its operation value set to the value of the operation "xxxx".
+
+**3.20 local information exchange:** The exchange of generic functional data between ROSE or other ASEs which are located in the DSS 2 entities at either side of the access.
+
+**3.21 network:** The DSS 2 protocol entity at the network side of the user-network interface.
+
+**3.22 non-local information exchange:** The exchange of generic functional data between ROSE or other ASEs for which one, or other, or both, are not located in the DSS 2 entities at either side of the access.
+
+**3.23 outgoing network:** An outgoing transport entity that is also a network, i.e. DSS 2 protocol entity at the network side of the interface. For bearer-related transport, the outgoing network is also the originating network.
+
+**3.24 outgoing transport entity:** An entity that initiates a transport mechanism.
+
+**3.25 outgoing user:** An outgoing transport entity that is also a user, i.e. DSS 2 protocol entity at the user side of the interface. For bearer-related transport, the outgoing user is also the originating user.
+
+**3.26 party control message:** A message as defined in 8.1.2/Q.2971 [14], which on sending or receipt causes a change in party state at either the network or the user.
+
+**3.27 party state:** States for each party in the call (see 7.2.1/Q.2971 [14]) which are known at the interface.
+
+- 3.28 responder:** The entity (user or network) responding to a request from an initiator on establishing a signalling connection.
+- 3.29 return result APDU:** See 9.4.2.2. Where reference is made to an "xxxx" return result APDU, a return result APDU is meant which is related to an "xxxx" invoke APDU.
+- 3.30 return error APDU:** See 9.4.2.3. Where reference is made to an "xxxx" return error APDU, a return error APDU is meant which is related to an "xxxx" invoke APDU.

+# 5 Description
+
+## 5.1 Overview
+
+The generic functional protocol provides a means of exchanging ROSE APDU on behalf of signalling applications in peer entities. These signalling applications may either be for the support of supplementary services, or provide protocol for the support of other functionality (e.g. look ahead). This exchange may take place either in association with a bearer established using DSS 2 procedures, or may be carried independently of any bearer.
+
+The exchange of ROSE APDU between signalling applications may be local or non-local to the user-network interface.
+
+### 5.1.1 Local information exchange
+
+If the exchange of information is local (i.e. one signalling application exists at the network and the peer signalling application exists at the user), no addressing information is required, unless there is a need to select from multiple signalling entities at the user side of the interface, e.g. as in the multiple subscriber number supplementary service.
+
+The exchange of information may be using any of:
+
+- a) bearer-related transport;
+- b) connectionless bearer-independent transport;
+- c) connection-oriented bearer-independent transport.
+
+This does not preclude a local exchange of information being used for the support of a signalling application on a more global basis; usage in this form is dependent on the specification of the individual signalling application itself. The exchange is local between a signalling application in the local network and a signalling application in the local user. As a result of receiving these APDUs, the signalling application in the local network may establish a signalling association with other signalling applications eventually incorporating the remote user.
+
+Non-local information exchange is outside the scope of this part of this Recommendation. Requirements for non-local information exchange will be covered in other parts of this Recommendation.
+
+### 5.1.2 Non-local information exchange
+
+If the exchange of information is non-local, then addressing information is required. This addressing information may be provided by using a value associated with a particular abstract functionality, or by explicitly using an ISDN number to identify the signalling endpoint. This non-local exchange could be entirely within the DSS 2 protocol (i.e. across a single exchange between two user-network interfaces). A more common occurrence will be to map this mechanism in DSS 2 into equivalent functionality within either broadband private network signalling protocols, or into TCAP protocol associated with the broadband NNI protocol.
+
+## 5.2 Protocol architecture
+
+Figure 1 shows the conceptual model for the generic functional protocol and its relation to the basic call model defined in Recommendation Q.2931 [13].
+
+At the top layer (the signalling application layer) the actual supplementary service protocol, or other signalling application protocol, operates between peer Application Service Control (AS-Control)
+
+entities which are service specific. The operation of specific AS-Control entities is beyond the scope of this Recommendation.
+
+AS-Control entities use the services of the Remote Operations Service Element (ROSE) via the coordination function. These entities use the services of the Generic Functional Transport Control (GFT-Control) via the coordination function.
+
+The coordination function provides coordination between GFT-Control (and the individual transport functions controlled by GFT-Control), the various AS-Control entities and ROSE, in addition to the functions performed for basic call.
+
+The provision and application of this model is for the purpose of description within this Recommendation, and is expected only to constrain implementations in terms of provision of the protocol on the access. Implementations are free to use any internal architecture providing the requirements of the protocol are met.
+
+![Diagram of the DSS 2 protocol model showing the Coordination function at the center, connected to a Telecommunication service application above, and SAAL-UNI below. To the right of the Coordination function are AS-Control #1, AS-Control #n, ROSE, GFT-Control, CL-BI, CO-BI, and point-to-point call/connection (Note).](75f0cb39f1cd165dfe4a6aa6c4d9388d_img.jpg)
+
+The diagram illustrates the DSS 2 protocol model. At the top is a box labeled 'Telecommunication service application'. Below it is a large vertical box labeled 'Coordination function'. At the bottom is a box labeled 'SAAL-UNI'. To the right of the 'Coordination function' box, there are several smaller boxes stacked vertically: 'AS-Control #1', a vertical ellipsis, 'AS-Control #n', 'ROSE', 'GFT-Control', 'CL-BI', 'CO-BI', and 'point-to-point call/connection (Note)'. Double-headed arrows connect the 'Telecommunication service application' to the 'Coordination function', the 'Coordination function' to the 'SAAL-UNI', and each of the boxes on the right to the 'Coordination function'. A small arrow points left from the 'SAAL-UNI' box. The text 'T1179540-96' is located to the right of the 'SAAL-UNI' box.

+
+NOTE – Call/connection control is included for the transport of bearer-related information. Although only the point-to-point call/connection control described in Recommendation Q.2931 [13] is shown, the point-to-multipoint call/connection control described in Recommendation Q.2971 [14] is also applicable.

+## 5.3 Application of the protocol model to local information exchange
+
+Figure 1 shows an example of the flow of information in the protocol model for the case where the signalling applications to be associated in communication are in adjacent nodes, e.g. between a DSS 2 user and a DSS 2 network using the CO-BI transport mechanism. Other transport mechanisms could be used as described in 5.1.1.

The diagram shows five stacked protocol entities: AS-Control, ROSE, GFT-Control, CO-BI, and SAAL-UNI. Vertical double-headed arrows connect adjacent entities within each node. Horizontal dashed double-headed arrows connect corresponding entities between the User node and the Network node. A 'Coordination function' is indicated by a dashed box surrounding the AS-Control, ROSE, GFT-Control, and CO-BI entities in both nodes. The SAAL-UNI entities are outside this box.

+
+## 5.4 Services provided by individual protocol entities
+
+### 5.4.1 Services provided by ROSE
+
+ROSE provides a set of services to AS-Control to support the ROSE protocol. These services are specified in Recommendation X.219 [3].
+
+### 5.4.2 Services provided by GFT-control
+
+This entity provides the following services to AS-Control and ROSE via the coordination function:
+
+- a) *Bearer-related service*
+  - GFT-Setup: request for the transfer of data in the bearer establishment phase. This service is a confirmed service;
+  - GFT-Release: request for the transfer of data in the bearer release phase. This service is a confirmed service;
+  - GFT-Reject: rejection of the ability to use a transport mechanism. This service is an unconfirmed service;
+  - GFT-Data: request for the transfer of data in active phase of a bearer. This service is an unconfirmed service.
+- b) *Connectionless bearer-independent service*
+
+- GFT-Unit Data: request for the transfer of data. This service is an unconfirmed service.
+- c) *Connection-oriented bearer-independent service*
+- GFT-Setup: request for the establishment of a bearer-independent signalling association (with data transfer if required). This service is a confirmed service;
+  - GFT-Release: request for the release of a bearer-independent signalling association (with data transfer if required). This service is a confirmed service;
+  - GFT-Reject: rejection of the ability to use a transport mechanism. This service is an unconfirmed service;
+  - GFT-Data: request for the transfer of data in active phase of a bearer-independent signalling association. This service is an unconfirmed service.
+
+### 5.4.3 Services provided by bearer-related transport
+
+Any of the bearer-related procedures specified in Recommendations Q.2931 [13] and Q.2971 [14] can be used for bearer-related protocol control. As multiconnection protocol provides the bearer control using the procedures of Recommendation Q.2931 [13], no extra services are required for transport in relation to multiconnection calls. The services provided by these entities are specified in those. In addition, these services provide one additional service:
+
+- BR-Data: this service is an unconfirmed service.
+
+A notification service is already provided within Recommendations Q.2931 [13] and Q.2971 [14].
+
+### 5.4.4 Services provided by connectionless bearer-independent transport
+
+Connectionless bearer-independent transport provides the following services to GFT-Control via the coordination function:
+
+- CL-BI-Unit Data: This service is an unconfirmed service.
+
+### 5.4.5 Services provided by connection-oriented bearer-independent transport
+
+Connection-oriented bearer-independent transport provides the following services to GFT-Control via the coordination function:
+
+- CO-BI-Setup: this service is a confirmed service;
+- CO-BI-Release: this service is a confirmed service;
+- CO-BI-Reject: this service is an unconfirmed service;
+- CO-BI-Data: this service is an unconfirmed service.
+
+In addition, connection-oriented bearer-independent transport also supports a notification data transfer service as follows:
+
+- CO-BI-Notification: this service is an unconfirmed service.
+
+# 6 Operational requirements
+
+## 6.1 Provision and withdrawal
+
+There are no direct requirements for provision and withdrawal of capabilities within this Recommendation. Provision and withdrawal of applications using this Recommendation are specified in the Recommendations describing those applications.
+
+Support of options within this Recommendation is conditioned by Recommendations defining the use of this Recommendation. However, in particular:
+
+- support of each individual transport mechanism is optional, although at least one transport mechanism shall be supported;
+- support of the requirements as presented by GFT-Control and as described in 9.3 is mandatory, although support of procedures associated with individual protocol profile values within the Facility information element is optional, and at least one value of protocol profile shall be supported;
+- if the value of protocol profile "ROSE" is supported, then the procedures relating to ROSE shall also be supported;
+- support of the use of the Called party number information element within the bearer-independent transport mechanisms is dependent on the support of the multiple subscriber number supplementary service;
+- support of the use of the Called party subaddress information element within the bearer-independent transport mechanisms is dependent on the support of the subaddressing supplementary service;
+- support of the use of the Calling party number information element within the bearer-independent transport mechanisms is dependent on the support of the multiple subscriber number supplementary service.
+
+## **6.2 Requirements on the originating network side**
+
+The requirements for provision of capabilities of this Recommendation are dependent on applications using this Recommendation. Capabilities in this Recommendation are therefore network and user options, but may become mandatory according to the requirements of other Recommendations.
+
+## **6.3 Requirements on the destination network side**
+
+The requirements for provision of capabilities of this Recommendation are dependent on applications using this Recommendation. Capabilities in this Recommendation are therefore network and user options, but may become mandatory according to the requirements of other Recommendations.

+
+NOTE – The following guidelines apply for the application of the different length encodings:
+
+- the short form definitive length encoding should be used to indicate the length of a data value with a length less than 128 octets;
+- when the long form definitive length encoding is used, the minimum number of octets should be used;
+- OCTET STRING and BIT STRING values should be encoded in a primitive form.
+
+Receiving entities shall be able to interpret all length forms of the basic encoding rules.
+
+##### **8.2.2.2.1 Treatment of existing Q.2931 information elements as parameters**
+
+Supplementary service or additional basic call capability protocol specifications are expected to require new parameters to be defined and to require existing Q.2931 [13] information elements.
+
+New parameters shall be defined using X.209 [7] coding, or Recommendation X.690 [9] as appropriate, if they do not appear elsewhere in Q.2931 [13] messages.
+
+Supplementary service or additional basic call capability protocol specifiers may elect to encapsulate one or more existing Q.2931 [13] information elements within an X.209 [7] data element, or X.690 [9] data element, as appropriate, thereby retaining the Q.2931 [13] coding for these information elements. When this option is chosen, all the Q.2931 [13] information elements should be grouped together as the content following the Q.2931 [13] information elements tag. This data element may appear by itself or as a member of a sequence or set.
+
+Encapsulation of the Facility information element within Facility information elements shall not be used.
+
+A formal definition of this mechanism using ASN.1, as specified in Recommendation X.208 [6], is given in A.2. A formal definition of this mechanism using ASN.1, as specified in Recommendation X.680 [8], is given in Table B.2.
+
+# **9 Signalling procedures at the coincident S<sub>B</sub> and T<sub>B</sub> reference point**
+
+## **9.1 APDU transport mechanisms**
+
+The transport function for operations is performed by the exchange of APDUs via DSS 2 messages.
+
+A supplementary service or additional basic call capability functional protocol (using the Facility information element) may use an existing bearer-related call reference if it is to be coupled to the connection, or it may use a bearer-independent call reference.
+
+### **9.1.1 Bearer-related transport**
+
+NOTE – The definition of "Bearer-related transport mechanism" is given in 3.3.
+
+The procedures for connection control are described in clause 5/Q.2931 [13]. These procedures are not influenced by the APDUs carried. Bearer-related transport procedures and operations shall operate independently of each other.
+
+#### 9.1.1.1 Normal operation
+
+For bearer-related transport any call/connection control message, any party control message, and the messages defined in 8.1.1, may be used to carry the APDUs in a Facility information element. These messages shall use the call reference of the bearer connection.
+
+The FACILITY message shall not be sent in the following call/connection states:
+
+- Null (0) (U0) (N0);
+- Call Initiated (1) (U1) (N1);
+- Call Present (6) (U6) (N6);
+- Release Request (11) (U11) (N11);
+- Release Indication (12) (U12) (N12).
+
+The call reference provides the means to correlate messages belonging to the same connection. When a supplementary service or additional basic call capability affects more than one connection, different call references are used to identify each connection individually. This implies the use of different messages in order to manage each connection separately.
+
+When the call/connection associated with the AS-Control functionality is cleared due to AS-Control actions, the Cause information element in the clearing message shall be set to #16 "normal clearing".
+
+NOTE – Any additional reason for clearing is included in the APDUs generated by AS-Control, and therefore transferred in the Facility information element.
+
+When indicated by GFT-Control, generic functional data shall be included in a Facility information element and transferred in a call control message or party control message if such a message is being sent for other reasons, or else in a FACILITY message.
+
+The transport mechanism shall pass all valid received generic functional data and protocol profile values in the Facility information element to GFT-Control and the procedures specified in GFT-Control (see 9.3) shall also apply.
+
+#### 9.1.1.2 Exceptional procedures
+
+If the network or user recognizes a supplementary service or additional basic call capability request in a received SETUP message but is not able to process the request, then the following options shall apply:
+
+- the network or user may clear the call request and reject the supplementary service or additional basic call capability invocation by means of an appropriate call-clearing message which contains the Cause information element and a return error APDU with the appropriate parameters in the Facility information element;
+- the network or user may continue to process the call request according to the call control procedures of Recommendation Q.2931 [13], and reject the supplementary service or additional basic call capability invocation by including a return error APDU with the appropriate parameters in the Facility information element by means of a FACILITY message or in an appropriate call/connection control message or party control message.
+
+The option to be used depends on the individual supplementary service or additional basic call capability procedures which are the subject of other Recommendations.
+
+In addition, when the network or user identifies an error in the received APDU, the network or user may continue to process the call request according to the call control procedures of Recommendation Q.2931 [13], and ignore the supplementary service or additional basic call capability invocation, in which case a reject component shall be generated.
+
+No response message shall be sent after the call reference value has been released.
+
+The procedures of 9.1.1 are an extension to the procedures of Recommendations Q.2931 [13] and Q.2971 [14]. As such the general error handling procedures as defined in 5.6/Q.2931 [13] and 9.5/Q.2971 apply. However, the handling of errors in octet 5 of the Facility information element is specified in 9.3.2. The handling of errors in APDUs is specified in Appendix III. If the connection is being cleared, the treatment of outstanding supplementary service or additional basic call capability requests is subject to the Recommendations for the individual supplementary services or additional basic call capabilities.
+
+### **9.1.2 Bearer-independent transport mechanisms**
+
+This subclause and 9.1.3 and 9.1.4 define the transport of APDUs independently of a connection. This Recommendation utilizes the signalling AAL connection services as described in Recommendation Q.2130 [15]. The messages used for transport (i.e. CO-BI SETUP, CONNECT, FACILITY and RELEASE) may carry the Facility information elements containing the application-oriented operation APDUs.
+
+The correlation among the various transport messages is provided by means of the call reference value of each message.
+
+The bearer-independent transport functions are divided into the following two categories:
+
+- connection-oriented (Note);
+- connectionless (Note).
+
+NOTE – A definition of the terms "connection-oriented" and "connectionless" is given in clause 3.
+
+Within this subclause, signalling AAL service primitives are used to illustrate the communication between protocol layers and are not intended to specify or constrain implementations.
+
+### **9.1.3 Connection-oriented bearer-independent transport mechanism**
+
+The procedures in this subclause describe a connection-oriented service which provides APDU transfer between signalling entities outside the context of a bearer.
+
+The description of the protocol control requirements for connection-oriented bearer-independent transport uses a set of states defined in 7.2.1.3.
+
+#### **9.1.3.1 Actions in the Null state**
+
+When asked to initiate a Bearer-independent signalling connection by GFT-Control, the outgoing transport entity shall:
+
+- a) ensure that a reliable SAAL connection exists. If a reliable SAAL connection does not exist, the transport entity shall establish a reliable SAAL connection according to the procedures described in Recommendation Q.2130 [15];
+- b) send a CO-BI SETUP message on the appropriate SAAL connection which shall contain only:
+  - a call reference, selected according to 4.3/Q.2931 [13];
+  - if indicated by GFT-Control, one or more Facility information elements;
+
+- if indicated by any AS-Control entity, one or more Notification indicator information elements.
+
+NOTE – In addition, the CO-BI SETUP message may also be extended with the Called party number information element, the Calling party number information element, and the Called party subaddress information element as described in 9.2.
+
+- c) start timer T303; and
+- d) enter the Call Initiated state.
+
+On receipt of a CO-BI SETUP message relating to establishment of a bearer-independent signalling connection, the incoming transport entity shall:
+
+- i) if the request is valid and can be processed, indicate the connection request to GFT-Control and enter the Call Present state; or
+- ii) if the request is invalid or cannot be accepted by the GFT-control, return a RELEASE COMPLETE message to the outgoing transport entity, release the call reference and remain in the Null state.
+
+#### **9.1.3.2 Actions in the Call Present state**
+
+If indicated by GFT-Control, the incoming transport entity shall return a CALL PROCEEDING message to the outgoing transport entity, and shall enter the Incoming Call Proceeding state.
+
+If indicated by GFT-Control, the incoming transport entity shall return a CONNECT message to the outgoing transport entity, and shall enter the Active state.
+
+#### **9.1.3.3 Actions in the Call Initiated state**
+
+On receipt of a CALL PROCEEDING message from the incoming transport entity, the outgoing transport entity shall stop timer T303, and enter the Outgoing Call Proceeding state.
+
+If no response is received before timer T303 expires, the outgoing transport entity shall inform GFT-Control of the failure of the signalling connection request and enter the Null state.
+
+NOTE 1 – A clearing cause value of #102 "recovery on timer expiry" shall be indicated for use in any protocol signalling to a preceding entity.
+
+NOTE 2 – If the connection-oriented procedures are not supported by a GFT-Control which receives a CO-BI SETUP message, and the instruction indicators in the Message type information element do not indicate a different course of action, it will respond with a RELEASE COMPLETE message indicating, cause #81 "invalid call reference value". This will initiate connection release in accordance with 9.1.3.8.
+
+#### **9.1.3.4 Actions in the Incoming Call Proceeding state**
+
+When receiving an indication that the bearer-independent signalling connection is established from GFT-Control, the incoming transport entity shall: send a CONNECT message to the outgoing transport entity and enter the Active state.
+
+The CONNECT message shall contain:
+
+- if indicated by GFT-Control, one or more Facility information elements;
+- if indicated by any AS-Control entity, one or more Notification indicator information elements.
+
+#### **9.1.3.5 Actions in the Outgoing Call Proceeding state**
+
+On receipt of a CONNECT message from the incoming transport entity, the outgoing transport entity shall: inform GFT-Control that the signalling connection is established and enter the Active state.
+
+#### **9.1.3.6 Actions in the Active state**
+
+In the Active state a FACILITY message can be sent or received.
+
+#### **9.1.3.7 Connection release**
+
+When a transport entity is requested by GFT-Control to release a bearer-independent signalling connection, the transport entity shall:
+
+- if in the Release Request state, ignore the request from GFT-Control; or
+- if in any other transport entity state, send a RELEASE message with an appropriate cause value, start timer T308 and enter the Release Request state.
+
+When Transport entity makes a local decision to release a bearer-independent signalling connection (e.g. due to a protocol error), it shall, if not in the Release Request state: inform GFT-Control that the signalling connection has been released, send a RELEASE message, start timer T308 and enter the Release Request state.
+
+The RELEASE message shall contain:
+
+- an appropriate cause value;
+- if indicated by GFT-Control, one or more Facility information elements;
+- if indicated by any AS-Control entity, one or more Notification indicator information elements.
+
+On receipt of a RELEASE message in any state other than the Release Request state, the transport entity shall indicate to GFT-Control that the signalling connection has been released, stop all timers, send a RELEASE COMPLETE message, release the call reference and enter the Null state.
+
+On receipt of a RELEASE COMPLETE message in any state other than the Release Request state, the transport entity shall indicate to GFT-Control that the signalling connection has been released, stop all timers, release the call reference and enter the Null state.
+
+#### **9.1.3.8 Actions in the Release Request state**
+
+On receipt of a RELEASE or a RELEASE COMPLETE message, the transport entity shall: stop timer T308, release the call reference and enter the Null state.
+
+If timer T308 expires for the first time, the RELEASE message shall be retransmitted and timer T308 shall be restarted. If timer T308 expires a second time, the transport entity shall release the call reference and enter the Null state.
+
+#### **9.1.3.9 Transport of APDUs associated with a connection-oriented bearer-independent signalling connection**
+
+When indicated by GFT-Control, generic functional data shall be included in a Facility information element and transferred in a bearer-independent control message if such a message is being sent to establish or clear the signalling transaction, or, whilst in the Active state, in a FACILITY message.
+
+The transport mechanism shall pass all valid received generic functional data and protocol profile values in the Facility information element to GFT-control and the procedures specified in GFT-Control (see 9.3) shall also apply.
+
+#### **9.1.3.10 Transport of notifications**
+
+The delivery of bearer-independent notifications shall use an active call reference of the connection-oriented transport mechanism. In this context, a call reference shall be active from the initiation of
+
+establishment (i.e. the CO-BI SETUP message) to the initiation of clearing (i.e. the RELEASE message).
+
+If the delivery of the notification coincides with establishment or clearing, the notification information can be carried in a bearer-independent control message. In all other cases, the notification information shall be delivered in a NOTIFY message. In addition a NOTIFY message may be sent or received by the DSS 2 entity only after the first response to a CO-BI SETUP message has been sent or received and before the clearing of the call reference is initiated.
+
+If a notification is received by the network, the network shall optionally ensure that the contents of the notification are a valid coding; and forward the notification to the other user involved in the call.
+
+No state change shall occur at either side of the interface following sending or receipt of a NOTIFY message.
+
+If a receiving CO-BI transport entity has no related AS-Control entity – i.e. a relationship between AS-Control entities does not yet exist, will not be created as a result of the received message, or has ceased to exist – then the received notification shall be discarded.
+
+#### **9.1.3.11 Protocol error handling**
+
+Subclause 5.6/Q.2931 [13] shall apply with the following modifications:
+
+- actions regarding the handling of VCIs and VPCIs are not applicable;
+- if a SETUP ACKNOWLEDGE, ALERTING or PROGRESS message (defined in ITU-T Recommendation Q.2931 [13]) is received in any state (except the Null state, where invalid call reference error procedures apply) it shall be treated as an unexpected or unrecognised message in accordance with 5.6.4/Q.2931 [13];
+
+These general error handling procedures only apply for octet 1 through 4 of the Facility information element. The handling of errors in octet 5 is specified in 9.3.2.
+
+Subclause 5.6.11/Q.2931 [13] shall apply for the generation and request of bearer-independent connection state information.
+
+### **9.1.4 Connectionless bearer-independent transport mechanism**
+
+#### **9.1.4.1 Normal operation**
+
+The connectionless transport mechanism is based on FACILITY messages. However, the connectionless transport mechanism shall only use the dummy call reference value as specified in 4.3/Q.2931 [13].
+
+Before data can be sent the transport entity shall first ensure establishment, if not already available, of a reliable signalling AAL connection using the signalling AAL\_ESTABLISH.request service primitive as described in Recommendation Q.2130 [15]. Completion of establishment of this connection is indicated by a signalling AAL\_ESTABLISH.confirm primitive.
+
+The FACILITY message is used to carry the "user" information, i.e. the APDU structures in the Facility information element.
+
+NOTE – In addition, the FACILITY message may also be extended with the Called party number information element, the Calling party number information element, the Called party subaddress information elements described in 9.2.
+
+When indicated by GFT-Control, the transport entity shall include generic functional data in one or more Facility information elements and shall transfer this information in a FACILITY message.
+
+The transport entity shall pass all valid received generic functional data and protocol profile values in the Facility information element to GFT-Control and the procedures specified in GFT-Control (see 9.3) shall also apply.
+
+#### **9.1.4.2 Exceptional procedure**
+
+If the message action indicator is to be applied to a received FACILITY message as a result of error handling, the receiver shall treat the "clear call" and "discard and report status" values as if "discard and ignore" had been received.
+
+If the instruction indicator is to be applied for a received information element, the receiver shall treat the "clear call" and discard "message and report status" values as if "discard message and ignore" had been received.
+
+If a FACILITY message is received and it does not contain the Facility information element, the receiving entity shall discard the FACILITY message.
+
+If a FACILITY message is received that contains a Facility information element with invalid content in octets 1 to 4, then that Facility information element and the FACILITY message shall be ignored and no action taken on the contents of the FACILITY message.
+
+If a FACILITY message is received that contains an unexpected information element, an unrecognized information element, or an optional information element with content error, and explicit actions are not applied, then that information element shall be ignored, and action taken on the message and those information elements that are recognized and have valid content.
+
+If either transport entity receives an indication that the signalling AAL connection has been released via the signalling AAL\_RELEASE.indication primitive, or that the signalling AAL connection has spontaneously been reset via the signalling AAL\_ESTABLISH.indication primitive, then the procedures as they affect the supplementary service or additional basic call capability are outside the scope of this Recommendation.
+
+NOTE – The handling of layer 2 errors is dependent on the supplementary service or additional basic call capability and are therefore specified in the individual Recommendation referencing this subclause.
+
+## **9.2 Addressing of APDUs**
+
+### **9.2.1 Local addressing**
+
+Within this part of this Recommendation communication is entirely local, i.e. an association exists between an AS-Control entity in the user and an AS-Control entity in the network. However, there exists the possibility that multiple AS-Control entities may exist in the user, and identification/addressing of these is performed by either the multiple subscriber number supplementary service or the subaddressing supplementary service. Figure 4 shows the associated architecture for multiple terminal applications as described above.
+
+![Diagram of protocol architecture for multiple subscriber number and subaddressing supplementary services. It shows a network stack and three user stacks (user 1, user 2, user 3). The network stack has AS-Control, GFT-Control, transport mechanism, and SAAL. The user stacks have the same layers. User 1's transport mechanism is labeled 'number = A, subaddr = X'. User 2's transport mechanism is labeled 'number = A, subaddr = Y'. User 3's transport mechanism is labeled 'number = B'. All transport mechanisms connect to a common SAAL layer.

+
+On receipt of a Calling party number information element in a CO-BI SETUP message by the outgoing network, the network shall apply the same procedures to the Calling party number information element as are specified in 1.9.1.1/Q.2951.2 [11] for basic call.
+

+
+On receipt of a Called party number information element in a CO-BI SETUP message by the incoming user, the network shall apply the same procedures to the Called party number information element as are specified in 1.9.1.2/ Q.2951.2 [11] for basic call.
+
+#### **9.2.2.3 Connectionless bearer-independent transport mechanism**

+
+On receipt of a Calling party number information element in a FACILITY message by the incoming network, the network shall apply the same procedures to the Calling party number information element as are specified in 1.9.1.1/Q.2951.2 [11] for basic call.
+
+The incoming network may include in the FACILITY message a Called party number information element. The coding of the Called party number information element shall follow the same requirements as specified for the SETUP message in 1.9.2.1/Q.2951.2 [11]. An exception is that no protocol is returned.
+
+On receipt of a Called party number information element in a FACILITY message by the incoming user, the user shall apply the same procedures to the Called party number information element as are specified in 1.9.1.2/Q.2951.2 [11] subclause for basic call.
+
+### **9.2.3 Additional transport procedures where the subaddressing supplementary service applies**
+
+#### **9.2.3.1 Bearer-related transport mechanism**
+
+The subaddressing supplementary service applies only to the bearer as described in Recommendation Q.2951.8 [12].
+
+#### **9.2.3.2 Connection-oriented bearer-independent transport mechanism**
+
+The incoming network may include in the CO-BI SETUP message a Called party subaddress information element. The coding of the Called party subaddress information element shall follow the same requirements as specified for the SETUP message in 1.9.2.1/Q.2951.8 [12].
+
+On receipt of a Called party subaddress information element in a CO-BI SETUP message by the incoming user, the user shall apply the same procedures to the Called party subaddress information element as are specified in 1.9.2.2/Q.2951.8 [12] for basic call.
+
+#### **9.2.3.3 Connectionless bearer-independent transport mechanism**
+
+The incoming network may include in the FACILITY message a Called party subaddress information element.

+
+## **9.3 GFT-Control**
+
+This subclause provides the limited procedures for GFT-Control when local addressing only is supported.
+
+### **9.3.1 Transmission of generic functional data**
+
+When ROSE or any other ASE requires to transmit generic functional data, this is indicated to GFT-Control. GFT-Control shall:
+
+- determine from the information supplied by ROSE or any other ASE the transport mechanism required;
+- ensure that the required transport mechanism is in a state to transmit generic functional data;
+
+- where it is required to establish a new connection-oriented bearer-independent transport mechanism, then on receipt of an indication from the transport mechanism that a CALL PROCEEDING message has been received, GFT-Control shall start timer T310. On receipt of an indication from GFT-Control that a CONNECT message has been received, GFT-Control shall stop timer T310. If T310 expires, then the appropriate AS-Control shall be informed of the failure to send generic functional data;
+
+NOTE 1 – A clearing cause value of #102 "recovery on timer expiry" shall be indicated for use in any protocol signalling to a preceding entity.
+
+- supply to the appropriate transport mechanism the generic functional data and protocol profile based on the type of ASE requesting transport of generic functional data. In particular, for the support of ROSE for local addressing within the constraints of this part of this Recommendation, the protocol profile shall be set to "ROSE";
+- indicate the instruction indicator for use in the Facility information element;  
+NOTE 2 – The prime function of the instruction indicator in the Facility information element is to provide corrective action when the generic functional protocol is not supported.
+- indicate any required address for the multiple subscriber number or subaddressing supplementary service.
+
+If GFT-Control is unable to provide the transfer of generic functional data, it shall indicate this to ROSE or any other appropriate ASE.

+### 9.3.2 Receipt of generic functional data

+When a transport mechanism receives a Facility information element, this is indicated to GFT-Control.
+
+GFT-Control shall check the protocol profile, and if it is valid it shall indicate this data to the appropriate ASE. In particular, if the protocol profile is set to "ROSE", this shall be indicated to the ROSE ASE. If the protocol profile is set to a reserved value, or to a value of protocol profile that is not supported, the generic functional data shall be discarded, and the procedures for unrecognized information element content specified in 5.6.8.2/Q.2931 or 5.7.2/Q.2931 [13], as appropriate, shall be followed on the appropriate transport mechanism. The error handling rules in subclauses 5.6.8.2/Q.2931 and 5.7.2/Q.2931 [13] shall apply only for errors in the octets 1 through 5 of the Facility information element. Errors in subsequent octets shall be handled according to the appropriate ROSE procedures.
+
+## 9.4 Remote operations procedures
+
+### 9.4.1 Introduction
+
+The generic functional protocol provides a means of exchanging generic functional data and is specified as a realization of ROSE (see Recommendations X.219 [3] and X.880 [17]).
+
+### 9.4.2 Procedures for operations
+
+The specification of procedures for operations of this subclause is according to the definition of elements of procedure of Recommendations X.229 [2] or X.880 [17], but uses only those elements which are specified for application within the Facility information element of this Recommendation. In addition, this subclause includes some extensions to ROSE concerning the error procedures. Recommendations X.229 [2] and Recommendation X.880 [17] provide consistent specifications of the remote operation procedures and the application of one or the other depends on the version of the abstract syntax used for the specification of the remote operations by the AS-Control entities.
+
+The procedures for operations are defined in terms of the interactions between peer-to-peer protocol machines through the use of a transport mechanism of the DSS 2 protocol. The operation protocol comprises of the following procedures:
+
+- invocation;
+- return result;
+- return error; and
+- reject.
+
+The structure, contents and encoding of the appropriate APDUs are defined in 8.2. Dependent on the specific operation, return result and return error APDUs can be applicable. This is specified in the Recommendation of the individual applications.
+
+In the following subclauses a summary of the procedures of each of these APDUs is given as far as applicable to this Recommendation.
+
+#### 9.4.2.1 Invocation
+
+An application entity (invoker) shall use the invocation procedure to initiate an operation to be performed by the other application entity (performer). The invocation procedures shall use the invoke APDU as described in Table A.1. The invoke APDU shall be delivered towards the remote peer entity within a Facility information element sent within an appropriate transport message (e.g. call/connection control messages, party control messages, bearer-independent control messages, or FACILITY messages).
+
+The operation value shall be used to identify the operation to be invoked, e.g. a specific supplementary service, a part of a specific supplementary service or a generic function.
+
+The invoke identifier shall be used to identify the request of a ROSE-invoke service (10.1/X.219 [3]) and to correlate this request with the corresponding replies. The value is assigned by the invoker.
+
+The invoke identifier shall be significant within a certain call reference value. The value (invoke identifier, call reference, signalling AAL connection endpoint identifier) shall uniquely identify an instance of an operation. In this respect the dummy call reference shall be regarded as a call reference as well.
+
+An invoke identifier value shall not be reused as long as a response is expected pertaining to the invocation identified by this invoke identifier.
+
+The linked identifier shall be used within a ROSE-invoke service (10.1/X.219 [3]), when the invoked operation is a child operation and this parameter identifies the linked parent operation.
+
+#### **9.4.2.2 Return result**
+
+An AS-Control entity (performer) shall use the return result procedure to request the transfer of the result of a successfully performed operation to the other AS-Control entity (invoker). The return result procedure shall use the return result APDU as described in Table A.1.
+
+The return result APDU shall be delivered towards the remote peer entity in a Facility information element within an appropriate transport message.
+
+#### **9.4.2.3 Return error**
+
+An AS-Control entity (performer) shall use the return error procedure to request the transfer of the error information in the case of an unsuccessfully performed operation to the other AS-Control entity (invoker). The return error procedure shall use the return error APDU as described in Table A.1. Error values shall be defined specifically for each individual operation.
+
+The return error APDU shall be delivered towards the remote peer entity in a Facility information element within an appropriate transport message.
+
+#### **9.4.2.4 Reject**
+
+An AS-Control entity shall use the reject procedure to reject the request (invocation) or reply (result or error) of the other AS-Control entity. The reject procedure shall be used by the receiver when the received request or reply cannot be processed because of errors in the received APDU (e.g. mistyped APDU or unrecognized operation). The receipt of a reject APDU shall not result in the start of a reject procedure.
+
+In addition, a reject component may also be generated by ROSE for the same reasons as apply in the application.
+
+The reject procedure shall use the reject APDU as described in Table A.1 and shall use the definition of problems as specified in Table 11. The reject APDU shall be delivered towards the remote peer entity in a Facility information element within an appropriate transport message.

+#### **9.4.2.5 Formal definition of data types**
+
+The formal definition of the OPERATION and ERROR macro shall be as given in Figure 4/X.219 [3] and is described in ASN.1 using the ASN.1 macro concept. These macros shall be used in the Recommendations of the individual supplementary services to define the required operations and errors.
+
+NOTE – These definitions are reproduced in Appendix III.
+
+# **10 Procedures for interworking with private ISDNs**
+
+## **10.1 APDU transport mechanisms**
+
+The transport function for operations is performed by the exchange of APDUs via DSS 2 messages as specified in Recommendation Q.2931 [13].
+
+A supplementary service or additional basic call capability functional protocol (using the Facility information element) may use an existing bearer-related call reference if it is to be coupled to the connection, or it may use a bearer-independent call reference.
+
+### **10.1.1 Bearer-related transport**
+
+The procedures shall be as specified in 9.1.1.
+
+### **10.1.2 Bearer-independent transport mechanisms**
+
+The two transport mechanisms specified in 9.1.2 shall apply, i.e. the connection-oriented bearer independent transport mechanism and the connectionless bearer-independent transport mechanism.
+
+NOTE – It is recommended that the connection-oriented transport mechanism is used for procedures that are specific for interworking with private ISDNs. This is however application-dependent and specified in Recommendations using the procedures of this Recommendation.
+
+### **10.1.3 Connection-oriented bearer-independent transport mechanism**
+
+The procedures of 9.1.3 shall apply.
+
+### **10.1.4 Connectionless bearer-independent transport mechanism**
+
+The procedures of 9.1.4 shall apply.
+
+## **10.2 Addressing of APDUs**
+
+The procedures of 9.2.1 shall apply. The procedures for the multiple subscriber number or subaddressing supplementary services are not applicable at the T<sub>B</sub> reference point for interworking with private ISDNs.
+
+## **10.3 GFT-Control**
+
+This subclause provides the limited procedures for GFT-Control when local addressing only is supported.
+
+The procedures of 9.3 shall apply.
+
+## **10.4 Generic functional protocol**
+
+The procedures of subclause 9.4 shall apply.
+
+# **11 Interactions with other networks**
+
+This clause provides procedures for interworking between DSS 2 and other access protocols (e.g. DSS 1), through an interworking unit. It also therefore indicates possible appropriate mappings where more complex functionality intervenes.
+
+## 11.1 Interworking with N-ISDNs
+
+Two means exist for interworking with the N-ISDN. In the first the generic functional protocol is fully terminated. In the second, a generic interworking function is provided.
+
+An interworking function shall either provide the procedures in 11.1.1 or those in 11.1.2. The alternative procedures cannot be used on a case-by-case basis.
+
+NOTE – While 11.1.2 provides the simpler functionality, it is only possible to use this functionality when all supplementary services or additional basic call functionality using the generic functional protocol that it is desired to interwork across the interworking function has equivalent procedural requirements and equivalent abstract and concrete syntax definitions in both the DSS 1 and DSS 2 protocols. Where these conditions do not apply, then 11.1.1 should be used.
+
+### 11.1.1 Full termination of generic functional protocol

Dotted double-headed arrows indicate interworking between corresponding layers: AS-Control to AS-Control, Rec. Q.932 to GFT-Control, and Rec. Q.921 to SAAL.

+#### Fully terminated interworking
+
+In this situation the generic functional protocol is fully terminated in the interworking unit, and interworking requirements are therefore specified by the ITU-T Recommendation specification giving the AS-Control entity requirements. These procedures are therefore outside the scope of this Recommendation. Within the interworking function the procedures of clauses 9 or 10 shall apply at the DSS 2 side as appropriate.

+#### Generic interworking
+
+For this form of interworking to take place, the supplementary service procedures or other functionality for both DSS 1 and DSS 2 are identical with the exception of the transport mechanism. The same operation and error values shall be used in both protocols for the same supplementary service or other functionality.
+
+The procedures for interworking the various transport mechanisms are given in the following subclauses.
+
+#### 11.1.2.2 Bearer-related transport mechanism
+
+All mapping is performed as specified in 6/Q.2931 [13], with the addition that the Facility information element is included in all mapped messages.
+
+In addition, for mapping DSS 2 to DSS 1 the mappings shown in Table 12 shall apply.

+The DSS 2 Facility information element is mapped to the DSS 1 Facility information element by removing its second octet and adjusting the length indication without causing other changes to the contents.
+
+The DSS 1 Facility information element is mapped to the DSS 2 Facility information element by inserting the second octet and changing length indication field from one to two octets, adjusting the length accordingly, without causing other changes to the contents. The flag bit in the second octet is set to "0", i.e. the normal error handling procedures as defined in 5.6/Q.2931 apply.
+
+#### **11.1.2.3 Connection-oriented bearer independent mechanism**

+## **12.1 Connection-oriented bearer-independent transport**
+
+Table 18 defines the values and attributes of the protocol timers required for the connection-oriented bearer-independent transport entity.
+
+In Table 18, the following conventions are used to indicate the applicability of the protocol timers to an incoming transport entity or outgoing transport entity:
+
+M: The support of the timer is Mandatory.
+
+O: The support of the timer is Optional.
+
+M(I): The support of the timer is Mandatory if the associated (optional) procedures are implemented.
+
+All timer values given in Table 18 shall have a tolerance of 10%. Where minimum and maximum values are given, the choice of value is an implementation matter, within the range specified, with a tolerance of 10% below the minimum value and 10% above the maximum value.

+The diagram illustrates the sequence of messages for a connection-oriented bearer-independent transport mechanism. It features two vertical lifelines: 'Outgoing entity' on the left and 'Incoming entity' on the right, each represented by a circle at the top. The message sequence is as follows: 1. The Outgoing entity sends a 'CO-BI SETUP Fie' message to the Incoming entity. 2. The Incoming entity responds with a 'CALL PROCEEDING' message. 3. The Incoming entity then sends a 'CONNECT Fie' message. 4. This is followed by a 'FACILITY Fie' message from the Incoming entity. 5. A second 'FACILITY Fie' message is sent by the Incoming entity. 6. The Outgoing entity then sends a 'RELEASE Fie' message. 7. Finally, the Outgoing entity sends a 'RELEASE COMPLETE Fie' message.

+## **ITU-T RECOMMENDATION Q.2934**
+
+## **DIGITAL SUBSCRIBER SIGNALLING SYSTEM No. 2 – SWITCHED VIRTUAL PATH CAPABILITY**
+
+## **Summary**
+
+This Recommendation specifies the procedures for establishing, maintaining, and clearing of switched virtual path connections. It specifies extensions to Recommendations Q.2931 [1], Q.2961.1 [2], Q.2961.2 [3], Q.2961.3 [4], Q.2961.4 [5] and Q.2961.6 [6] to provide this capability.
+
+### **Source**
+
+ITU-T Recommendation Q.2934 was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 15th of May 1998.
+
+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# 7 Primitive definitions and state definitions
+
+## 7.1 Primitive definitions
+
+Clause 8/Q.2931 [1] shall apply.
+
+## 7.2 State definitions
+
+No additional states to those specified in Recommendation Q.2931 [1] are required.
+
+# 8 Coding requirements – Information elements
+
+See clause 4/Q.2931 [1], clause 8/Q.2961.1 [2], clause 6/Q.2961.2 [3], clause 8/Q.2961.3 [4] and clause 8/Q.2961.4 [5]. This clause identifies the changes to support the switched virtual path capability.
+
+## 8.1 Broadband bearer capability
+
+The definition of the broadband bearer capability information element given in Recommendations Q.2961.2 [3], Q.2961.3 [4], Q.2961.4 [5] and Q.2961.6 [6] is extended as shown in Table 1 below. The following codepoint is added to the bearer class field in octet 5:
+
+**Table 1/Q.2934 –Broadband bearer capability information element**
+
+|                  |                        |
+|------------------|------------------------|
+| Bits (Octet 5)   |                        |
+| <u>5 4 3 2 1</u> |                        |
+| 1 1 0 0 0        | Transparent VP Service |
+
+## 8.2 Connection identifier
+
+The codepoint 100 shall be added to the preferred/exclusive field in octet 5 in Table 4-16/Q.2931 [1], and a Note 4 shall be added as follows:
+
+Bits (Octet 5)
+
+3 2 1
+
+0 0 1 Exclusive VPCI; any VCI (see Note 4)
+
+1 0 0 Exclusive VPCI; no VCI (see Note 4)
+
+NOTE 4 – In the restart procedure, either "Exclusive VPCI; any VCI" or "Exclusive VPCI; no VCI" may be used to indicate a virtual path to be restarted.
+
+Note 1 in Figure 4-22/Q.2931 [1] shall be replaced with the following Note:
+
+NOTE 1 – If the preferred/exclusive field indicates "any VCI" or "no VCI", the VCI field shall be ignored.
+
+## 8.3 Restart indicator
+
+For the following two class field codepoints the semantics and Notes 2 and 3 shall be changed as follows:
+
+Bits (Octet 5)
+
+3 2 1
+
+0 0 1 indicated switched virtual path or all virtual channels in the indicated VPC which are controlled via the signalling channel on which the RESTART message is sent (see Note 2)
+
+0 1 0 all Switched Virtual Channels and switched virtual paths controlled by the layer 3 entity which sends the RESTART message (see Note 3)
+
+NOTE 2 – The connection identifier information element shall be included and indicates the switched virtual path to be restarted or the virtual path connection in which all Switched Virtual Channels are to be restarted. The virtual channel identification field in the connection identifier information element is ignored.
+
+NOTE 3 – The connection identifier information element is not included. All Switched Virtual Channels and paths controlled by the point-to-point signalling channel are to be restarted.
+
+## 8.4 OAM traffic descriptor
+
+In 4.5.24/Q.2931 [1], Figure 4-30/Q.2931 [1] and Table 4-22/Q.2931 [1], replace all occurrence of "OAM F5 flow" with "OAM F4 flow".
+
+The following sentence is added to the last part of 4.5.24/Q.2931 [1]:
+
+"OAM traffic descriptor information element is used for OAM F4 flow in case of SVP, and OAM F5 flow in case of SVC".
+
+In 4.5.6/Q.2931 [1] and Annex I/Q.2931 [1], replace all occurrence of "OAM F5 flow" with "OAM F4 flow" except in the Note in I.3.
+
+# 9 Signalling procedures at the coincident S<sub>B</sub> and T<sub>B</sub> reference point
+
+This clause identifies changes to the procedures of Recommendations Q.2931 [1], Q.2961.1 [2], Q.2961.3 [4], Q.2961.4 [5] and Q.2961.6 [6] to support the switched virtual path capability.
+
+## 9.1 Call/connection establishment at the origination interface
+
+### 9.1.1 Associated signalling
+
+Associated signalling does not apply when supporting switched virtual paths.
+
+### 9.1.2 Non-associated signalling
+
+In order to request the establishment of a switched virtual path the user shall set the bearer class field of the bearer capability information element in the SETUP message to "Transparent VP Service", and shall indicate one of the following in the connection identifier information element:
+
+- c) No indication is included (i.e. the connection identifier information element is not included in the SETUP message); or
+- d) Exclusive VPCI; no VCI.
+
+In case c), the network selects any available VPCI.
+
+In case d), if the indicated VPCI is available, the network selects it for the call.
+
+The selected VPCI is indicated in the connection identifier information element in the first message returned by the network in response to the SETUP message (e.g. CALL PROCEEDING). The VP associated signalling field is coded as "explicit indication of VPCI". The preferred/exclusive field is coded as "exclusive VPCI; no VCI".
+
+In case c), if the network is not able to allocate a VPCI, a RELEASE COMPLETE message with Cause #45 "No VPCI/VCI available" is sent by the network.
+
+In case d), if the indicated VPCI is not available, a RELEASE COMPLETE message with Cause #35 "Requested VPCI/VCI not available" is sent by the network.
+
+## 9.2 Call/connection establishment at the destination interface
+
+### 9.2.1 Associated signalling
+
+Associated signalling does not apply when supporting switched virtual paths.
+
+### 9.2.2 Non-associated signalling
+
+When the establishment of a switched virtual path is requested (i.e. the bearer class field of the bearer capability information element in the SETUP message indicates "Transparent VP Service"), the network shall indicate one of the following:
+
+- c) No indication is included (i.e. the connection identifier information element is not included in the SETUP message); or
+- d) Exclusive VPCI; no VCI.
+
+In case c), the user selects any available VPCI.
+
+In case d), if the indicated VPCI is available, the user selects it for the call.
+
+The selected VPCI is indicated in the connection identifier information element in the first message returned by the user in response to the SETUP message (e.g. CALL PROCEEDING). The VP associated signalling field is coded as "explicit indication of VPCI". The preferred/exclusive field is coded as "exclusive VPCI; no VCI". If the connection identifier information element is not present in the first response message, the connection identifier in the SETUP message shall be assumed.
+
+In case c), if the user is not able to allocate a VPCI, a RELEASE COMPLETE message with Cause #45 "*No VPCI/VCI available*" is sent by the user.
+
+In case d), if the indicated VPCI is not available, a RELEASE COMPLETE message with Cause #35 "*Requested VPCI/VCI not available*" is sent by the user.
+
+### 9.2.3 Compatibility check
+
+Subclause 5.2.2.2.1/Q.2931 [1] shall apply. Only broadband category 1 compatibility information is applicable to switched virtual paths. Currently, no equivalent broadband category 2 compatibility information is defined for switched virtual paths.
+
+## 9.3 Restart procedure
+
+This subclause identifies changes to the restart procedures of Recommendation Q.2931 [1] to support the switched virtual path capability. The changes are shown under the specific section headers of Recommendation Q.2931 [1].
+
+*5.5/Q.2931 Restart procedure:*
+
+Replace line 1 of paragraph 2 by:
+
+The restart procedure is used to return a Switched Virtual Channel, all Switched Virtual Channels in a virtual path, a switched virtual path, or all Switched Virtual Channels and switched virtual paths controlled by the signalling virtual channel to the idle condition.
+
+Replace line 3 of Note by:
+
+In the case where the same Switched Virtual Channel(s) or switched virtual path(s) are specified, they shall not be considered free for reuse until all relevant restart procedures are completed.
+
+*5.5.1/Q.2931 Sending RESTART:*
+
+*5.5.1.1/Q.2931 Normal procedure*
+
+Replace paragraph 1 by:
+
+A RESTART message is sent by the network or user equipment in order to return Switched Virtual Channels or switched virtual paths to the idle condition. The Restart indicator information element shall be present in the RESTART message to indicate whether an "Indicated Switched Virtual Channel", "indicated switched virtual path or all Switched Virtual Channels in a virtual path" or "all Switched Virtual Channels and switched virtual paths controlled by the layer 3 entity" are to be restarted. If the Restart indicator information element is coded as "indicated Switched Virtual Channel" or "indicated switched virtual path or all Switched Virtual Channels in a virtual path", then the connection identifier information element shall be present to indicate which Switched Virtual Channel or switched virtual path is to be returned to the idle condition. If the Restart indicator information element is coded as "all Switched Virtual Channels and switched virtual paths controlled by the layer 3 entity", then the connection identifier information element shall not be included.
+
+Replace lines 3 and 4 of paragraph 2 by:
+
+Receipt of a RESTART ACKNOWLEDGE message stops timer T316 and indicates that the Switched Virtual Channel(s)/switched virtual path(s) and associated resources [e.g. call reference value(s)] can be freed for reuse. The Null state will be entered after the Switched Virtual Channel/switched virtual path and call reference value are released.
+
+Replace paragraph 4 by:
+
+Calls associated with restarted Switched Virtual Channel(s)/switched virtual path(s) shall be cleared towards the remote parties using Cause #41, "*Temporary failure*".
+
+#### 5.5.1.2/Q.2931 Exceptional procedures
+
+Replace line 2 of paragraph 1 by:
+
+While timer T316 is running, the Switched Virtual Channel(s)/switched virtual path(s) being restarted shall not be used to support new calls requested using the call set-up procedures.
+
+Replace line 6 of paragraph 1 by:
+
+The Switched Virtual Channel(s)/switched virtual path(s) is considered to be in an out-of-service condition until maintenance action has been taken.
+
+Replace paragraph 2 by:
+
+If a RESTART ACKNOWLEDGE message is received indicating a different set of Switched Virtual Channel(s)/switched virtual path(s) from the set indicated in the RESTART message, the RESTART ACKNOWLEDGE message shall be discarded.
+
+### 5.5.2/Q.2931 Receipt of RESTART:
+
+#### 5.5.2.1/Q.2931 Normal procedures
+
+Replace line 1 of paragraph 1 by:
+
+Upon receiving a RESTART message the recipient shall enter the Restart state associated to the global call reference and start timer T317; it shall then initiate the appropriate internal actions to return the specified Switched Virtual Channel(s)/switched virtual path(s) to the idle condition and release all call references associated with it.
+
+Replace paragraph 2 by:
+
+Calls associated with restarted Switched Virtual Channel(s)/switched virtual path(s) shall be cleared towards the remote parties using Cause #41, "*Temporary failure*".
+
+Replace paragraph 3 by:
+
+Even if all the specified Switched Virtual Channel(s)/switched virtual path(s) are in the idle condition, or already in the process of restart to the idle condition, receiving entity shall transmit a RESTART ACKNOWLEDGE message to the originator upon receiving a RESTART message.
+
+Replace paragraph 4 by:
+
+If the Restart indicator information element is coded as "all Switched Virtual Channels and switched virtual paths controlled by the layer 3 entity which sends the RESTART message", then all calls on all interfaces associated with the signalling virtual channel shall be cleared.
+
+In paragraph 5, replace all occurrences of "all user plane virtual channels in the indicated VPC controlled via the signalling virtual channel in which the RESTART message is sent" by "indicated switched virtual path or all Switched Virtual Channels in a virtual path".
+
+In paragraph 7, replace all occurrences of "virtual channels" by "Switched Virtual Channels and switched virtual paths".
+
+#### 5.5.2.2/Q.2931 *Exceptional procedures*
+
+Replace paragraphs 2, 3 and 4 by:
+
+If the Restart indicator information element is coded as "all Switched Virtual Channels and switched virtual paths controlled by the layer 3 entity which sends the RESTART message" and a connection identifier information element is included, the connection identifier information element is treated as described in 5.6.8.3/Q.2931 [1].
+
+If the Restart indicator information element is coded as "indicated Switched Virtual Channel" or "indicated switched virtual path or all Switched Virtual Channels in a virtual path" and the connection identifier information element is not included, then the procedures in 5.6.7.1/Q.2931 [1] shall be followed.
+
+If the Restart indicator information element is coded as "indicated Switched Virtual Channel" or "indicated switched virtual path or all Switched Virtual Channels in a virtual path" and the connection identifier information element contains an unrecognizable VPCI, then the procedures in 5.6.7.2/Q.2931 [1] shall be followed.
+
+If the restart Indicator information element in the received RESTART message is coded "indicated Switched Virtual Channel" and the VPCI indicated in Connection identification information element is being used for an active switched virtual path, then the procedures in 5.6.7.2/Q.2931 [1] shall be followed.
+
+# 10 Procedures at the T<sub>B</sub> reference point for interworking with private B-ISDNs
+
+The procedures of clause 9 apply.
+
+# 11 Interworking with other networks
+
+## 11.1 Interworking with entities which do not support the SVP capability
+
+If an entity which does not support the SVP capability described in this Recommendation receives a broadband bearer capability information element identifying the transparent VP service in a SETUP message, it shall follow the procedures described in 5.6, 5.7 and 5.8/Q.2931 [1].
+
+## 11.2 Interworking with N-ISDN
+
+For SVPs interworking with an N-ISDN entity is not possible. SVP call/connection requests shall be rejected at the interworking point with Cause #63 "*Service or option not available, unspecified*".
+
+# 12 Interactions
+
+## 12.1 Interactions with supplementary services
+
+The support of the SVP capability described in this Recommendation has no impact on the support of the CLIP, CLIR, COLP, COLR, DDI, SUB, MSN, CUG, and UUS supplementary services as specified in Recommendations Q.2951 [11], Q.2955 [12], and Q.2957 [13].
+
+## 12.2 Interactions with other capabilities
+
+If negotiation of SVP connection characteristics during call/connection set-up is supported, the procedures of Recommendation Q.2962 [7] apply. In this case, the connection characteristics of the SVP may be negotiated during call/connection establishment by means of the alternative traffic descriptor or the minimum acceptable traffic descriptor.
+
+If connection modification is supported for SVPs, the procedures of Recommendations Q.2963.1 [8] and Q.2963.2 [9] apply.
+
+If connection modification with negotiation is supported for SVPs, the procedures of Recommendation Q.2963.3 [10] apply.
+
+The support of the SVP capability described in this Recommendation has no impact on the support of Look-ahead and Call Priority capabilities as specified in Recommendations Q.2964.1 [14] and Q.2959 [15].
+
+# 13 Timers
+
+See clause 7/Q.2931 [1]. No additional timers are defined.
+
+# 14 Dynamic description (SDLs)
+
+See Annex A/Q.2931 [1]. No additional SDLs are defined.
+
+# ANNEX A
+
+## Valid combinations of bearer class, broadband transfer capability and ATM traffic descriptor parameters
+
+The parameters specified in the broadband bearer capability information element, and the ATM traffic descriptor information element of the SETUP message shall be consistent. Table A.1 shows the valid combinations of the bearer class, BTC, and ATM traffic descriptor parameters for the SVP capability.
+
+NOTE 1 – The BTC values considered in Table A.1 are the ones applicable at the time of publication of this Recommendation. This does not preclude other combinations to be defined in future when new BTC values are specified.
+
+If a SETUP message is received with a broadband bearer capability information element containing any other combination of values in octet 5 and octet 5a than those specified in Table A.1, a RELEASE COMPLETE message shall be returned with Cause #65, "*Bearer capability not supported*".
+
+If the combination of traffic parameters, excluding the tagging field, in a SETUP message is not a valid combination specified in Table A.1 for the received values of octet 5 and octet 5a in the broadband bearer capability information element, it shall be considered an unsupported combination of traffic parameters and a RELEASE COMPLETE message shall be returned with Cause #73, *"Unsupported combination of traffic parameters"*.
+
+Table A.1 identifies the ATM transfer capability requested for the given direction of the connection. The implicitly requested QoS row in Table A.1 identifies the QoS requested when the QoS Class is 0. In addition, Table A.1 identifies the I.371 [16] ATM transfer capability that supports the requested ATM transfer capability and the I.356 [17] QoS class that supports the implicitly requested QoS.
+
+NOTE 2 – Recommendation I.371 [16] constrains the ATM transfer capability to be the same for both directions of a connection.
+
+Table A.2 identifies the ATM transfer capability which may be used to enable backward compatibility with ATCs not defined in Recommendation I.371 [16]. There is not a one-to-one correspondence between the codepoints of the BTC field and the ATM Transfer Capability (ATC) defined in Recommendation I.371 [16]. This is in part due to the need to be backward compatible with the first edition of Recommendation Q.2931 [1] (1995) and also due to the implicit association of End-to-end timing requirements for some of the BTC codepoints.
+
+At the S<sub>B</sub> reference point or coincident S<sub>B</sub>/T<sub>B</sub> reference point, a user compliant to this Recommendation shall not use these combinations in a transmitted SETUP message, but shall be able to accept these combinations on reception. A network compliant to this Recommendation shall relay these combinations.

+## Management of VPCI and bandwidth
+
+Mutually exclusive subsets of VPCIs need to be defined for Switched Virtual Channel (SVC) connections and Switched Virtual Path (SVP) connections. For SVPs, subsets should be defined on a physical interface basis.
+
+When sending a SETUP message the initiating entity would first try to select a VPCI from the subset(s) of VPCIs allocated for SVPs. Based on the connection request, bandwidth will be assigned to this VPCI from the pool of bandwidth associated with the VPCI subset the selected VPCI belongs to. The selected VPCI will be signalled in the connection identifier information element together with other parameters in the SETUP. If there is no available VPCI belonging to the subset(s) of VPCIs allocated for SVPs, or the available bandwidth is insufficient to satisfy the connection request, the entity will request the remote entity to allocate VPCI and bandwidth, i.e. the SETUP will be sent without the connection identifier information element.
+
+![A hierarchical diagram showing the management of VPCI and bandwidth resources. At the top level is 'VPCIs'. It branches into three categories: 'Subset of VPCIs for SVP – Interface 2', 'Subset of VPCIs for SVP – Interface 1', and 'Subset of VPCIs for SVC'. The 'Subset of VPCIs for SVP – Interface 1' category further branches into 'Subset of VPCIs – Assigning' and 'Subset of VPCIs – non-Assigning'. Both of these lead to a 'BW Pool'. The 'BW Pool' for the 'Assigning' category branches into four 'VPCI' labels, each of which leads to a 'BW' label. The 'BW Pool' for the 'non-Assigning' category leads to a single 'BW Pool' label.](5b8a756d9a71c35f17db8bcb90b438a3_img.jpg)

+# FOREWORD
+
+The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.2957, clause 1, was prepared by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 7th of February 1995.
+
+---
+
+## NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+## **SUMMARY**
+
+This Recommendation defines the operation of the Digital subscriber Signalling System No. 2 (DSS 2) for the support of the User-to-User Signalling (UUS) supplementary service at the  $T_B$  or the coincident  $S_B$  and  $T_B$  reference point of the user to network interface of the Broadband-Integrated Services Digital Network (B-ISDN).
+
+The User-to-User Signalling (UUS) supplementary service allows a B-ISDN user to send and receive a limited amount of information to/from another B-ISDN user over the signalling virtual channel in association with a call/connection to the other B-ISDN user.
+
+## STAGE 3 DESCRIPTION FOR ADDITIONAL INFORMATION TRANSFER SUPPLEMENTARY SERVICES USING B-ISDN DIGITAL SUBSCRIBER SIGNALLING SYSTEM No. 2 (DSS 2) – BASIC CALL
+
+(Geneva, 1995)
+
+# 1 User-to-User Signalling (UUS)
+
+## 1.1 Scope
+
+This Recommendation specifies the stage three of the User-to-User Signalling (UUS) supplementary service for the Broadband Integrated Services Digital Network (B-ISDN) at the  $T_B$  reference point or coincident  $S_B$  and  $T_B$  reference point (as defined in Recommendation I.413 [1]) by means of the Digital Subscriber Signalling System No. 2 (DSS 2) protocol. Stage three identifies the protocol procedures and switching functions needed to support a telecommunications service (see Recommendation I.130 [2]).
+
+In addition, this Recommendation specifies the protocol requirements at the  $T_B$  reference point where the service is provided to the user via an intermediate private B-ISDN.
+
+This Recommendation does not specify the additional protocol requirements where the service is provided to the user via a telecommunications network that is not a B-ISDN.
+
+The User-to-User Signalling (UUS) supplementary service allows a B-ISDN user to send/receive a limited amount of information to/from another B-ISDN user over the signalling virtual channel in association with a call/connection to the other B-ISDN user.
+
+For N-ISDN services supported in B-ISDN, see Recommendation I.257.1 [5]. For B-ISDN services, the applicability has yet to be defined.
+
+This Recommendation is applicable to equipment, supporting the UUS supplementary service, to be attached at either side of a  $T_B$  reference point or coincident  $S_B$  and  $T_B$  reference point when used as an access to the public B-ISDN.

+## 1.5 Description
+
+The UUS supplementary services provide a means of communication between two users by using as a basis the layer 3 protocol defined in clause 5/Q.2931 [3]. User-to-user signalling is used to exchange information between two users to provide the services described in the Stage 1 Service Description. The exchange of user-to-user signalling is limited by flow control procedures provided by the network or the user. The exchange of user-to-user information is not a network acknowledged service. Any acknowledgement procedure shall be controlled at a higher layer between users.
+
+Three UUS services associated with B-ISDN calls that may be provided by the network to users are:
+
+- a) *Service 1* – User-to-user information exchanged during the set-up and clearing phases of a call/connection, by transporting the User-user information element within Recommendation Q.2931 [3] call/connection control messages;
+- b) *Service 2* – User-to-user information exchanged from the sender's point of view during call/connection establishment, between the ALERTING and CONNECT messages, within USER INFORMATION messages; and
+- c) *Service 3* – User-to-user information exchanged while a call/connection is in the Active state, within USER INFORMATION messages.
+
+All three services may be used separately or in any combination in association with a single call. As an option, at call/connection set-up, users may be able to specify that the requested user-to-user signalling service(s) is (are) required for the call, i.e. the call should not be completed if user-to-user information cannot be passed.
+
+For B-ISDN Release 1, only UUS service 1 (implicitly requested) is specified and supported. UUS service 1 (explicitly requested), UUS service 2 and UUS service 3 are outside the scope of this Recommendation.
+
+## 1.6 Operational requirements
+
+### 1.6.1 Provision/withdrawal
+
+UUS service 1 must be subscribed to by the calling user.
+
+### 1.6.2 Requirements on the originating network side
+
+The basic call/connection control procedures according to 5.1/Q.2931 and 5.4/Q.2931 [3] are applicable.
+
+### 1.6.3 Requirements on the destination network side
+
+The basic call/connection control procedures according to 5.2/Q.2931 and 5.4/Q.2931 [3] are applicable.
+
+### 1.6.4 Assumptions made about the terminal
+
+Terminal equipment using UUS service 1 is expected to be able to generate and accept the User-user information element (see 1.8.3) as described in 1.9 below.
+
+## 1.7 State definitions
+
+The states associated with basic call/connection control according to Recommendation Q.2931 [3] are applicable.
+
+## 1.8 Coding Requirements
+
+### 1.8.1 Messages
+
+The following messages are applicable to the operation of service 1: SETUP, ALERTING, CONNECT, RELEASE, RELEASE COMPLETE, PROGRESS.
+
+Tables 1-1 to 1-6 show the message contents for UUS service 1 implicit.
+
+### 1.8.2 Codesets
+
+The UUS supplementary service information elements are in codeset 0.
+
+### 1.8.3 Information elements
+
+The User-user information element is applicable to the operation of service 1.
+
+The purpose of the User-user information element is to convey information between B-ISDN users. This information is not interpreted by the network, but rather is carried transparently and delivered to the remote user(s).
+
+The User-user information element shall be considered as an access information element (see Annex J/Q.2931 [3]).

+#### **User-user information element**
+
+## **1.9 Signalling procedures at the coincident S<sub>B</sub> and T<sub>B</sub> reference point**
+
+### **1.9.1 Activation/deactivation/registration**
+
+Service 1 shall be activated implicitly as described in 1.9.2 below. In this case, activation and operation of the service are indistinguishable.
+
+The procedures for call establishment are described in Recommendation Q.2931 [3] with the following modifications. On call request, the SETUP message sent by the calling user shall contain the service 1 request, i.e. the User-user information element.
+
+The SETUP message sent by the network towards the called user shall also contain the same service requests, i.e. the User-user information element.
+
+Deactivation procedures are not required to support service 1 implicit.
+
+### **1.9.2 Call establishment phase – Implicit operation**
+
+#### **1.9.2.1 Normal operation**
+
+Service 1 may be implicitly requested by including a User-user information element of variable length as specified in 1.8.2 in the SETUP message, transferred across the user-network interface at the calling side as described in 5.1.1/Q.2931 [3]. This information element is transported by the network and delivered unchanged in the User-user information element included in the SETUP message transferred across the user-network interface at the called side as described in 5.2.1/Q.2931 [3]. For activation purposes, this information element must be at least five octets long, as defined in 1.8.3.
+
+A User-user information element may be included in the ALERTING and/or CONNECT messages transferred across the user-network interface at the called side as described in 5.2.5/Q.2931 [3]. It may also be included in the RELEASE or RELEASE COMPLETE message (see 1.9.3). The content of this information element is transported by the network and delivered in the User-user information element included in the corresponding message(s) transferred across the user-network interface at the calling side as described in 5.1.6/Q.2931 and 5.1.7/Q.2931 [3].
+
+NOTE – In accordance with the Network Service Definition for Open Systems Interconnection, ISO 8348 | Recommendation X.213 [6], the called user may perform compatibility checking using the User-user information element contents (see Annex B/Q.2931 [3]). In the context of the OSI Network Service, service 1 may be used to support the conveyance of the NS-User-Data parameter of the N-CONNECT and N-DISCONNECT primitives.
+
+#### **1.9.2.2 Exceptional procedures**
+
+The network shall discard the User-user information element if it is received from the calling user in a SETUP message, but the calling user has not subscribed to UUS service 1. If the discard occurs, the network shall continue to process the call request. The network shall also inform the calling user that the UUS request is not accepted by sending a STATUS message containing cause No. 50 *requested facility non-subscribed*, or cause No. 43 *access information discarded*.
+
+The network shall discard the User-user information element if it is received from the called user in the ALERTING or CONNECT message, but a request for UUS was not indicated implicitly in the SETUP message delivered to the called user. If discard occurs, the network shall take action on the remaining contents of the message received from the calling user and shall send a STATUS message to the called user containing cause No. 43 *access information discarded*.
+
+The called user may not be able to interpret incoming User-user information elements. In such situations, the user should discard this information without disrupting normal call handling. No specific signalling is provided by the network to accommodate this situation.
+
+### **1.9.3 Call clearing phase**
+
+#### **1.9.3.1 Normal operation**
+
+A User-user information element may be included in the first message used to initiate the normal call clearing phase (see 5.4.3/Q.2931 and 5.4.4/Q.2931 [3]).
+
+The information contained in such an information element is transferred to the remote user in the first clearing message (see 5.3.3/Q.2931 and 5.3.4/Q.2931 [3]). Such a transfer is only performed if the information is received at the local exchange of the remote user before sending a clearing message to that user; otherwise, the information is discarded without sending any notification.
+
+A User-user information element may be included in the first normal clearing message sent by the called user during call establishment.
+
+If the called user rejects the call with a clearing message containing a User-user information element, the network shall deliver the User-user information element in the RELEASE message sent to the calling user. However, if the network is providing in-band information to the calling user, and chooses not to initiate clearing procedures at that time, the network may deliver the User-user information element in a PROGRESS message sent to the calling user.
+
+NOTE – It is intended that this capability may be used to provide the clearing data transfer (i.e. conveyance of the NS User-Data parameter to the N-DISCONNECT primitives) described in ISO 8348 | Recommendation X.213 [6].
+
+#### 1.9.3.2 Exceptional procedures
+
+The network shall discard the User-user information element if it is received from either user in a RELEASE or RELEASE COMPLETE message, but a request for UUS was not indicated implicitly in the SETUP message delivered to the called user. If discard occurs, the network shall take action on the remaining contents of the message received from the user. If the clearing party has sent a RELEASE message, the network shall send to the clearing party a RELEASE COMPLETE message containing cause No. 43 *access information discarded*. If the clearing party had sent a RELEASE COMPLETE message, the network shall consider the call as cleared to that party; no additional action shall be taken.
+
+The network shall discard the User-user information element in the following cases not explicitly discussed elsewhere in clause 9:
+
+- the overall length of the User-user information element is greater than 133 octets and UUS service 1 was activated implicitly;
+- the network receives a message containing the User-user information element, but that message is not allowed to contain UUS as defined by this Recommendation.
+
+If discard occurs, the network shall take action on the remaining contents of the message received from the sending user and shall send a STATUS message to that user containing cause No. 43, *access information discarded*. However, if the network discards a User-user information element from a received clearing message, the network shall include cause No. 43 *access information discarded*, in the next sequential clearing message sent to the user as specified in 5.4/Q.2931 [3]. If the network discards a User-user information element from a RELEASE COMPLETE message, the network shall consider the call as cleared to that party; no additional action shall be taken.
+
+## 1.10 Procedures for interworking with private networks
+
+The procedures described in 1.9 shall apply.
+
+NOTE – Generally, interworking between a public ISDN and a private ISDN is based on bilateral agreements.
+
+## 1.11 Interworking with other networks
+
+### 1.11.1 Interworking with N-ISDNs
+
+This subclause specifies the particular features to support access signalling interworking between B-ISDN and N-ISDN. The description of interworking assumes the communication scenario B as defined in Annex A/I.580 [7].
+
+#### Interworking N-ISDN → B-ISDN
+
+The DSS 1 User-user information element is mapped to the DSS 2 User-user information element by the terminal adapter or the interworking function by inserting octet 2 and changing the length indication from one to two octets.
+
+NOTE – It is recommended that the flag bit and the action indicator field in octet 2 is set as shown in Appendix I.
+
+#### Interworking B-ISDN → N-ISDN
+
+The DSS 2 User-user information element is mapped to the DSS 1 User-user information element by the terminal adapter or interworking function by removing its second octet and adjusting the length indication without causing other changes to the contents, and by respecting the order of this information element in the DSS 1 message.
+
+### **1.11.2 Interworking with non-ISDNs**
+
+In the case of interworking with a non-ISDN, the return of a PROGRESS or an ALERTING message with the Progress indicator information element indicating No. 1 *call is not end-to-end ISDN; further call progress information may be available in-band* to the calling user shall serve as indication that, in particular, the delivery of User-user information elements in call control messages cannot be guaranteed.
+
+In the case of interworking with a non-ISDN called user, the return of a PROGRESS or an ALERTING message with the Progress indicator information element indicating No. 2 *destination address is non-ISDN* to the calling user shall serve as indication that, in particular, the delivery of User-user information elements in call control messages cannot be guaranteed.

+
+## **Summary**
+
+This Recommendation specifies the Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT) proforma for the network at the  $T_B$  reference point or coincident  $S_B$  and  $T_B$  reference point (as defined in ITU-T I.413 [6]) of implementations conforming to the procedures for the handling of the connection characteristics negotiation during call/connection establishment phase of the Digital Subscriber Signalling System No. 2 (DSS2) protocol for the Broadband Integrated Services Digital Network (B-ISDN), ITU-T Q.2962 [1].
+
+Other Recommendations of the Q.2962 family specify the Protocol Implementation Conformance Statement (PICS) proforma and Test Suite Structure and Test Purposes (TSS & TP) based on this Recommendation.
+
+NOTE – This Recommendation related to protocol conformance is published only in English; it is based on an external SDO's standard published in English.
+
+### **Source**
+
+ITU-T Recommendation Q.2962 F was prepared by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 6 December 2000.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+## **Digital subscriber signalling system No. 2 – Connection characteristics negotiation during call/connection establishment phase: Abstract test suite (ATS) and partial protocol implementation extra information for testing (PIXIT) proforma for the network**
+
+# 1 Scope
+
+This Recommendation specifies the Test Suite Structure and Test Purposes (TSS & TP) for the network at the T<sub>B</sub> reference point or coincident S<sub>B</sub> and T<sub>B</sub> reference point (as defined in ITU-T I.413 [6]) of implementations conforming to the procedures for the handling of the connection characteristics negotiation during call/connection establishment phase of the Digital Subscriber Signalling System No. 2 (DSS2) protocol for the Broadband Integrated Services Digital Network (B-ISDN), ITU-T Q.2962 [1].
+
+Other Recommendations of the Q.2962 family specify the Protocol Implementation Conformance Statement (PICS) proforma and Test Suite Structure and Test Purposes (TSS & TP) based on this Recommendation.
+
+This Recommendation is applicable to equipment, supporting connection characteristics negotiation during call/connection establishment phase, to be attached at either side of a T<sub>B</sub> reference point or coincident S<sub>B</sub> and T<sub>B</sub> reference point when used as an access to the public B-ISDN.
+
+The ATS realizes test purposes identified in the TSS & TP part of the Recommendation and groups them according to the test suite structure given in the TSS & TP. Test purposes defined in the TSS & TP part but not testable are identified in this Recommendation.
+
+The supplier of a protocol implementation that is claimed to conform to ITU-T Q.2962 [1] is required to complete a copy of the PICS proforma and the PIXIT proforma provided by the testlab. The PIXIT proforma shall contain the tables identified in the partial PIXIT proforma part of this Recommendation and may contain additional information required by the testlab to be able to appropriately execute the test campaign.
+
+# 2 References

+## **BROADBAND INTEGRATED SERVICES DIGITAL NETWORK (B-ISDN) AND BROADBAND PRIVATE INTEGRATED SERVICES NETWORK (B-PISN) – CALL CONTROL PROTOCOL**
+
+## **Summary**
+
+This Recommendation specifies a signalling protocol for the purpose of call control at the  $Q_B$ ,  $S_B$ ,  $T_B$ , and co-incident  $S_B/T_B$  reference points within, between, and at the access to Broadband Private Integrated Services Networks and within, between, and at the access to Broadband Integrated Services Digital Networks. The protocol operates between two adjacent call control entities. The protocol is applicable to a terminal or network node in a separated call and bearer (connection) control environment for the support of calls having none, a single bearer or multiple bearers. The protocol is applicable to a two-party call. The protocol also provides forward compatibility to the extent that an implementation can also operate within a multi-party call with other implementations that use additional capabilities, provided the implementation is deployed where it does not need to be aware of more than two parties.

+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+
+*(Geneva, 1999)*
+
+# **1 Scope**
+
+This Recommendation specifies a signalling protocol for the purpose of call control at the Q<sub>B</sub>, S<sub>B</sub>, T<sub>B</sub>, and co-incident S<sub>B</sub>/T<sub>B</sub> reference points within, between, and at the access to Broadband Private Integrated Services Networks and within, between, and at the access to Broadband Integrated Services Digital Networks. The protocol operates between two adjacent call control entities. The protocol is applicable to a terminal or network node in a separated call and bearer (connection) control environment for the support of calls having none, a single bearer or multiple bearers. The protocol is applicable to a two-party call. The protocol also provides forward compatibility to the extent that an implementation can also operate within a multi-party call with other implementations that use additional capabilities, provided the implementation is deployed where it does not need to be aware of more than two parties.
+
+This Recommendation is related to other Recommendations in this series which will describe the architecture of a separated call and bearer control environment and scenarios in which such an architecture can be applied.
+
+The protocol specified in this Recommendation is independent of the supporting transport service.
+
+The protocol specified in this Recommendation is independent of the protocol used for bearer establishment.

+# **5 Basic model**
+
+## **5.1 Separation of call control and bearer control**
+
+The protocol specified in this Recommendation is applicable to an environment in which the control of a call is separate from the control of the bearer or bearers that exist within the context of that call.
+
+In order for two users to communicate using a telecommunication service, an association, or call, is established between the two users. Within the context of the call, one or more bearers can be established for transporting user plane information between the users. However, bearers are not normally established until the call has been accepted by the called terminal, and therefore resources required by bearers are not occupied unnecessarily if the call cannot be established, e.g. if the called terminal is unable to accept the call because resources are not available. During the lifetime of the call, bearers can be added or cleared down as required. The call is terminated by one of the two users when there is no further need for communication. Termination of the call implies that all bearers (if any) are cleared down.
+
+Although for some telecommunication services a single bearer is sufficient, other telecommunication services benefit from the use of multiple bearers, each tailored to suit the characteristics of the user plane information to be transported. This is particularly true for multimedia applications involving audio, video and data. The call provides a context in which the various bearers can exist and a means of binding the bearers together.
+
+## **5.2 Point-to-point and multi-party call control**
+
+In a point-to-point configuration the protocol specified in this Recommendation operates between any two adjacent call control entities between the calling party and the called party.
+
+In a multi-party configuration the protocol specified in this Recommendation operates between any two adjacent call control entities on the point-to-point leg between a coordination point in the network and a called party. In this case, a network node in the calling party's network takes responsibility for coordinating the responses from multiple point-to-point signalling associations to the called parties into one signalling association to the calling party. Enhancements to be made to the Call Control protocol in order to make it suitable also for this signalling association to the calling party in case of a multi-party call are outside the scope of this Recommendation.
+
+Figure 1 shows an example configuration for a multi-party call with two called parties involved.

+
+## 5.3 Call control architecture
+
+Call control provides the means of establishing, maintaining and clearing down a call, including the operation of any supplementary services that relate to the call rather than to individual bearers. Control of a call is effected by means of a number of call control entities (CC entities) located in the users' terminals and in various network nodes. Whereas bearer control involves a bearer control entity (BC entity) at each network node through which a bearer passes, call control requires a CC entity only at those network nodes that provide call-related functionality, e.g. the nodes serving the terminals concerned or nodes that, in the context of the call, provide interworking between networks. In particular, CC entities are not required at nodes that would only provide transit functionality. The precise criteria for determining whether a network node needs to provide CC functionality for a given call are outside the scope of this Recommendation.
+
+The various CC entities involved in a given call are linked in series by signalling associations. These CC entities and signalling associations are created during call establishment and cleared down when the call is cleared down. The protocol specified in this Recommendation provides such an association between adjacent CC entities and conveys call-related signalling information between those CC entities. That part of a call between two CC entities that communicate directly via a single signalling association is known as a call segment. This is illustrated in Figure 2 for a call that involves four CC entities (e.g. one at each terminal and one at each node serving those terminals) and consequently three call segments.
+
+![Figure 2/Q.2981 – Call Control involving four CC entities (three call segments). The diagram shows four boxes labeled 'CC' connected in a horizontal line by three double-headed arrows. Each arrow is labeled 'Call segment'. Below the fourth 'CC' box is the text 'T11102670-99'.](af7916c89a458fdab6c3f443217388ae_img.jpg)

+
+**Figure 2/Q.2981 – Call Control involving four CC entities (three call segments)**
+
+## 5.4 Relationship to bearer control architecture
+
+Bearer control requires functionality, and hence a BC entity, at each terminal and at every network node through which the bearer is routed. This is in contrast to call control, which involves a CC entity only at the terminals and selected network nodes. Each bearer can be routed independently of other bearers and independently of the routing of call control signalling associations. However, each bearer is required to be routed through each network node at which there is a CC entity, and hence have a BC entity at each of these nodes, so that the CC entity can manage the bearer if required. This is illustrated in Figure 3 for the same call as in Figure 2 and a single bearer that has a BC entity collocated with each CC entity and an additional BC entity (e.g. at a transit node) located between the second and third CC entities.
+
+![Figure 3/Q.2981 – Relationship of call control and bearer control architecture. The diagram shows a sequence of nodes: Terminal, Edge Switch, Transit Switch, Edge Switch, and Terminal. Each node contains a box with 'CC' and 'BC' entities, except for the Transit Switch which only contains a 'BC' entity. The nodes are connected by lines labeled 'Call segment'. Below the last 'Terminal' box is the text 'T11102680-99'.](cab0834804fb031b43865554cc8d06ab_img.jpg)

+
+NOTE – Signalling between BC entities is outside the scope of this Recommendation.
+
+## 5.5 Screening function
+
+The model for call and bearer control functional entities (Figure 3) shows all call control (CC) entities existing at the same location as bearer control (BC) entities. While bearer control can exist independently of call control, the opposite does not apply. Each CC entity includes bearer coordination capabilities.
+
+Although at network boundaries, CC entities will normally be present, network boundaries can also be crossed without provision of a CC entity and the connections associated with those calls can be routed differently from each other and from the call, thereby crossing network boundaries at different locations or even being routed through different networks.
+
+Where a call crosses a network boundary, a number of functions will need to be performed within call control that do not require the presence of a connection. These include:
+
+- Service control. Control of the provision of basic and supplementary services, and subscription arrangements. Identification of correct service profile.
+- Translation of numbering plans where the two networks use different numbering plans (e.g. public to private). Even where the same numbering plan is used, the addition of the country code may be necessary.
+- Provision of some supplementary services that provide security control on a network basis, e.g. closed user group.
+
+- d) Support of supplementary services related to numbering (e.g. DDI, MSN) and restriction of numbers (CLIR, COLR).
+
+The functions listed above are outside the scope of this Recommendation.

+
+The diagram illustrates a call path between a 'Calling user' and a 'Called user' across two networks, 'Network 1' and 'Network 2'.  
+At the 'Calling user' end, a 'CC' (Call Control) entity is connected to a 'TE' (Terminal Equipment). This 'CC' is linked via a dashed line (call segment) to another 'CC' at node 'A' inside 'Network 1'.  
+'Network 1' contains several nodes, with 'A' being the ingress point and 'B' being the egress point. A thick solid line (physical link on path of call) connects node 'A' to node 'B'.  
+At node 'B', the call segment (dashed line) continues to a 'CC' at node 'C' inside 'Network 2'.  
+'Network 2' also contains several nodes, with 'C' as the ingress point and 'D' as the egress point. A thick solid line connects node 'C' to node 'D'.  
+At node 'D', the call segment (dashed line) connects to a 'CC' which is then connected to the 'Called user' via its 'TE'.  
+A legend at the bottom left defines the line types:
+
+- Physical link
+- Physical link on path of call
+- Call segment
+- Allocation of CC to physical TE or network node

+
+**Figure 4/Q.2981 – Call originating and terminating in different networks**
+
+Figure 4 shows an example of a call originating and terminating in different networks. If calling line identification restriction (CLIR) applies to the call, this information will be known at the CC at node A, which can add a presentation restricted indicator to the calling party number forwarded on across the next call segment. Normally, on exit from one network to another, a calling party number with an associated presentation restricted indicator is not forwarded, but instead just the presentation restricted indicator is forwarded. The absence of a CC at node B (point of egress to network 2) means that there will be no opportunity to filter out the calling party number until the CC at node D is reached. This is clearly insecure.
+
+Possible alternatives are:
+
+- 1) Ensure that there is a CC at node B (and similarly at node C to handle this type of situation in the reverse direction). However, CCs are points of bearer coordination, and the presence of CCs at nodes B and C would force all bearers to go via nodes B and C. This would deny the possibility of using other routes between the two networks. For some bearers, the route via nodes B and C might not be the cheapest, or may be congested, or may not provide the desired quality of service. It is desirable to minimize the number of CCs in order to provide maximum flexibility for routing bearers.
+- 2) Ensure that the CC at node A performs the filtering. However, this requires node A to have knowledge that the call segment leads to another network. This knowledge may not always be available.
+
+To solve the problem without introducing the disadvantages of alternatives 1 and 2, filtering (screening) functionality may be provided at node B (and node C). A functional entity (screening function) may optionally appear between call control entities, and is located as necessary at incoming and outgoing gateways between networks. Figure 5 shows an example.
+
+The screening functional entity has no impact on the information flows, except that this functional entity may impose itself as a transit point on an existing flow.

+
+### 7.1.1 Service primitive architecture
+
+The following services for call establishment and release are defined:
+
+|                |             |
+|----------------|-------------|
+| ESTABLISH-CALL | confirmed   |
+| RELEASE-CALL   | confirmed   |
+| COMPLETE-CALL  | unconfirmed |
+| STATUS-CALL    | unconfirmed |
+| PROCEED-CALL   | unconfirmed |
+| ERROR          | indication  |
+
+Figure 6 shows the architecture which is assumed for two concatenated call segments.

+
+The diagram illustrates the architecture of the CC signalling service. It features three 'CC signalling service user' blocks at the top, each connected to a 'CC signalling service provider' block below it via a 'CC' interface. The first user connects to the first provider, the second user connects to the second provider, and the third user also connects to the second provider. The two providers are interconnected by a horizontal line.

+
+### 7.1.2 ESTABLISH-CALL
+
+This service is used by the call control signalling service user to establish a call and its information model. It is a confirmed service. See Figure 7. Table 1 shows the parameters of the ESTABLISH-CALL primitive.
+
+![Figure 7/Q.2981 – ESTABLISH-CALL service sequence diagram showing the interaction between a CC signalling service user, a CC signalling service provider, and another CC signalling service user.](a83ba9e3e2c1e21dd69953a7b09e45b4_img.jpg)
+
+The sequence diagram shows the interaction for the ESTABLISH-CALL service. It starts with a 'CC signalling service user' on the left sending an 'ESTABLISH-CALL request' to a 'CC signalling service provider' in the middle. The provider then sends an 'ESTABLISH-CALL indication' to another 'CC signalling service user' on the right. The right user responds with an 'ESTABLISH-CALL response' back to the provider, which in turn sends an 'ESTABLISH-CALL confirm' back to the left user. Dashed lines indicate the logical flow of the service between the user and the provider.

+
+## **7.2 Parameters**
+
+### **7.2.1 Call segment ID**
+
+A pair of values which together uniquely identify the call at the two adjacent CC entities bounding a call segment.
+
+### **7.2.2 Call description**
+
+The type CallDescription, as used in the operation callEstablish, contains an information model which describes the properties of a call. The information model comprises sequences of network relevant and end-to-end relevant object descriptions. An object description consists of:
+
+- an object reference, used to refer to particular instances of objects, which should therefore be unique within a particular call description;
+- an object status, which is used for example to indicate whether the object is optional or mandatory;
+- an identifier that identifies the class of object to which the instance belongs; and
+- an argument of type specific to the class of object to which the instance belongs.
+
+A call control object class is a class of object that inherits the properties of the super class CALLCONTROL OBJECT. Each object class in this super class comprises an identifier and an optional argument. The type of the argument depends on the particular object class in the super class, as identified by the identifier. The argument defines the type of attributes of an object of this class.
+
+The OpenCall parameter indicates to the non-call owners in a communications configuration their rights to modify the configuration. The OpenCall parameter is an attribute of the call that is set by the user (call control signalling service user); it is stored in the information model and is transferred in the call description. The call control protocol provides the procedures for exchanging information in an orderly manner. The call status change report provides the mechanism for informing all call control signalling service users involved in the call of one or more changes in the call permissions.
+
+### **7.2.3 Call changed parameter**
+
+The type CallChangedParameter, as used in the operation callStatus, contains a list of those objects of the information model which have been modified and the modification of which has to be reported to the other call control signalling service users involved in the call.
+
+### **7.2.4 Await complete indicator**
+
+Has the value TRUE if call and information model establishment uses a three-message sequence or FALSE if call and information model establishment uses an two-message sequence.
+
+### **7.2.5 Bearer establishment address**
+
+The address of a network node/terminal to which bearer (connection) establishment shall be routed.
+
+### **7.2.6 Release cause**
+
+Reason for a call release request.
+
+### **7.2.7 Result**
+
+Positive/negative result for an ESTABLISH-CALL request or indication.
+
+### **7.2.8 Diagnostics**
+
+Further explanation of the result (e.g. error values) in an ESTABLISH-CALL response/confirm or the explanation of the exceptional condition that caused an ERROR indication.
+
+## **7.3 Call control states**
+
+This subclause describes the states which exist for a CC signalling service provider within a CC entity.
+
+### **7.3.1 Call Idle**
+
+No call exists.
+
+### **7.3.2 Call Initiated**
+
+This state exists at a preceding CC entity when a request for call establishment has been sent to the succeeding CC entity but no response has been received.
+
+### **7.3.3 Outgoing Call Proceeding**
+
+This state exists at a preceding call control entity when acknowledgement that the call is accepted for this call segment has been received from the succeeding call control entity.
+
+### **7.3.4 Call Ready**
+
+This state exists at a preceding call control entity when an indication has been received from the succeeding CC entity that it is ready to complete the establishment of the call and its information model.
+
+### **7.3.5 Call Present**
+
+This state exists at a succeeding call control entity that has not yet responded to the request for call establishment.
+
+### **7.3.6 Incoming Call Proceeding**
+
+This state exists at a succeeding call control entity that has sent to the preceding call control entity acknowledgement that the call is accepted for this call segment.
+
+### **7.3.7 Await Call Completion**
+
+This state exists at a succeeding call control entity that is awaiting an indication from the preceding CC entity that establishment of the call and its information model is to be completed.
+
+### **7.3.8 Call Active**
+
+This state exists at a preceding call control entity that has received an indication that the called user has answered from the succeeding call control entity. This state exists at a succeeding call control entity that has sent an indication that the called user has answered to the preceding call control entity.
+
+### **7.3.9 Call Release Request**
+
+This state exists when a call control entity has sent out a request for call release but a response has not yet been received.
+
+### 7.3.10 Call Release Indication
+
+This state exists when a call control entity has received a call release indication but the user has not yet answered.

+# 9 Procedures
+
+## 9.1 Call establishment request
+
+### 9.1.1 Preceding CC entity
+
+On receipt of an ESTABLISH-CALL request primitive from the call control signalling service user, the preceding CC entity shall initiate call establishment by sending a callEstablish invoke APDU towards the succeeding CC entity and start timer T703. Following the transmission of the APDU, the preceding CC entity shall enter the Call Initiated state.
+
+The preceding CC entity shall include element awaitCompleteIndicator in the callEstablish invoke APDU reflecting the value (TRUE or FALSE) of the Await Complete Indicator parameter within the ESTABLISH-CALL request primitive and store this value locally as "Await Complete Indicator".
+
+The callEstablish invoke APDU shall contain the callSegmentId with the precedingSideCallSegId set to the value provided by the call control signalling service user and the succeedingSideCallSegId set to the null value. Within the argument of the callEstablish invoke APDU, element bearerEstablishmentAddress shall contain an address which, when used as a destination address for bearer establishment in the backward direction from the subsequent CC entity, causes the bearer to be routed to the preceding CC entity's terminal or network node, i.e. to the terminal or network node at the start of the call segment.
+
+The preceding CC entity shall include element callDescription in the callEstablish invoke APDU, as provided by the call control signalling service user.
+
+Prior to sending the callEstablish invoke APDU towards the succeeding CC entity, the preceding CC entity shall initiate establishment of a transport mechanism connection to the succeeding CC entity or use an existing transport mechanism (e.g. an already existing connection or a permanently available transport mechanism).
+
+NOTE – The CC protocol is independent of the underlying transport mechanism. It is therefore out of the scope of this Recommendation which transport mechanism is used.
+
+### 9.1.2 Succeeding CC entity
+
+On receipt of a callEstablish invoke APDU, the succeeding CC entity shall enter the Call Present state.
+
+The succeeding CC entity shall store the contents of element awaitCompleteIndicator as "Await Complete Indicator".
+
+The receipt of the callEstablish invoke APDU is indicated to the call control signalling service user with an ESTABLISH-CALL indication primitive.
+
+## 9.2 Call Proceeding
+
+### 9.2.1 Preceding CC entity
+
+On receipt of a callProceeding invoke APDU while in state Call Initiated, the preceding CC entity shall stop timer T703, start timer T710, and enter the Outgoing Call Proceeding state.
+
+The receipt of the callProceeding invoke APDU is indicated to the call control signalling service user with a PROCEED-CALL indication primitive.
+
+NOTE – This is the earliest time at which the CC signalling service user can establish bearer connections across this segment.
+
+### 9.2.2 Succeeding CC entity
+
+On request of the call control signalling service user (PROCEED-CALL request primitive) and while in state Call Present, the succeeding CC entity shall send a callProceeding invoke APDU to the preceding CC entity and enter the Incoming Call Proceeding state.
+
+The callProceeding invoke APDU shall contain the element callSegmentId with the precedingSideCallSegId set to the value as received in the callEstablish invoke APDU and the succeedingSideCallSegId set to the value provided by the call control signalling service user.
+
+Within the argument of the callProceeding invoke APDU, element bearerEstablishmentAddress shall contain an address which, when used as a destination address for bearer establishment in the forward direction from the preceding CC entity, causes the bearer to be routed to the succeeding CC entity's terminal or network node, i.e. to the terminal or network node at the end of the call segment.
+
+NOTE 1 – This is the earliest time at which the CC signalling service user can establish bearer connections across this segment.
+
+NOTE 2 – A bearer establishment can be initiated from either the call originating user or from the call destination user.
+
+## 9.3 Call accepted
+
+### 9.3.1 Preceding CC entity
+
+On receipt of the callEstablish return result APDU while in state Call Initiated or Outgoing Call Proceeding, the preceding CC entity shall stop timer T703 or T710 and:
+
+- if the value of stored item "Await Complete Indicator" is TRUE, then enter state Call Ready;
+- if the value of stored item "Await Complete Indicator" is FALSE, then enter state Call Active.
+
+The receipt of the callEstablish return result APDU is indicated to the call control signalling service user with an ESTABLISH-CALL confirm primitive.
+
+NOTE – If the callEstablish return result APDU was the first response received to a callEstablish invoke, this is the earliest time at which the CC signalling service user can establish bearer connections across this segment.
+
+### 9.3.2 Succeeding CC entity
+
+On request of the call control signalling service user (ESTABLISH-CALL response primitive), the succeeding CC entity shall send a callEstablish return result APDU to the preceding CC entity and:
+
+- if the value of stored item "Await Complete Indicator" is TRUE, then enter state Await Call Completion and start timer T701;
+- if the value of stored item "Await Complete Indicator" is FALSE, then enter state Call Active.
+
+The callEstablish return result APDU shall contain the element callSegmentId. If the succeeding CC entity has not previously sent a callProceeding invoke APDU, the argument of the callEstablish return result APDU shall contain element callSegmentId with the precedingSideCallSegId set to the value as received in the callEstablish invoke APDU and the succeedingSideCallSegId set to the value provided by the call control signalling service user. If it has previously sent a callProceeding invoke APDU, the argument of the callEstablish return result APDU shall contain element callSegmentId as indicated by the CC signalling service user.
+
+The callEstablish return result APDU shall contain the element CallDescription, as provided by the call control signalling service user in the ESTABLISH-CALL response primitive.
+
+If the succeeding CC entity has not previously sent a callProceeding invoke APDU, the argument of the callEstablish return result APDU shall contain element bearerEstablishmentAddress. This element shall contain an address which, when used as a destination address for bearer establishment in the forward direction from the preceding CC entity, causes the bearer to be routed to the succeeding CC entity's terminal or network node, i.e. to the terminal or network node at the end of the call segment.
+
+NOTE – This is the earliest time at which the CC signalling service user can establish bearer connections across this segment.
+
+## **9.4 Completion of call establishment**
+
+### **9.4.1 Preceding CC entity**
+
+On receipt of a COMPLETE-CALL request primitive while in state Call Ready, the preceding CC entity shall send a callComplete invoke APDU to the succeeding CC entity and enter state Call Active.
+
+The preceding CC entity shall include element callSegmentId in the callComplete invoke APDU.
+
+### **9.4.2 Succeeding CC entity**
+
+On receipt of a callComplete invoke APDU in state Await Call Completion, the succeeding CC entity shall enter state Call Active, stop timer T701 and give a COMPLETE-CALL indication primitive to the call control signalling service user.
+
+## **9.5 Call status change report**
+
+### **9.5.1 General**
+
+A change of the information model of a call is reflected in the Call Description belonging to that call. In order to report such a change to the peer CC entity, the callStatus operation, which contains the element callChangedParameter, shall be used. This element indicates changes to the original call description:
+
+- addition and deletion of a service component object;
+- changes to the attributes of a party object (i.e. modification of the status of a party);
+- changes to the OpenCall attribute of the call object (i.e. modification of the call permissions).
+
+A call status change report indicates one or more changes, but any deleted object shall not be referenced in a modified attribute.
+
+### **9.5.2 Initiating CC entity**
+
+On receipt of a STATUS-CALL request primitive while in state Await Call Completion or Call Active, the initiating CC entity shall send a callStatus invoke APDU and remain in the same state.
+
+The initiating CC entity shall include elements callSegmentId and callChangedParameter in the callStatus invoke APDU as indicated by the CC signalling service user.
+
+The element callChangedParameter contains a list of the changed objects such that:
+
+- where an object specified in the original Call Description is deleted, the value "deleteObject" shall be used, the objectReference shall be included, and modifiedArgument shall not be included;
+- where an object specified in the original Call Description is modified, the value "modifyAttributes" shall be used.
+
+### 9.5.3 Receiving CC entity
+
+On receipt of a callStatus invoke APDU in state Call Ready or Call Active, the receiving CC entity shall give a STATUS-CALL indication primitive to the call control signalling service user and remain in the same state.
+
+## 9.6 Call establishment failure
+
+### 9.6.1 Preceding CC entity
+
+On receipt of a callEstablish return error APDU while in state Call Initiated or Outgoing Call Proceeding, the preceding CC entity shall stop all timers (if timers are running) and enter the Call Idle state.
+
+Call establishment failure is indicated to the call control signalling service user by an ESTABLISH-CALL confirm primitive with negative Result parameter.
+
+NOTE – The call control signalling service user gives an indication to BC that the bearer connections for this call shall be cleared.
+
+Call establishment failure can also be indicated from the preceding CC entity while in state Call Ready to the succeeding CC entity by the use of the procedures for call clearing as defined in 9.7.
+
+### 9.6.2 Succeeding CC entity
+
+On call control signalling service user request (ESTABLISH-CALL response primitive with negative Result parameter) and while in state Call Present or Incoming Call Proceeding, the succeeding CC entity shall send a callEstablish return error APDU with a suitable error value and enter the Call Idle state.
+
+Suitable error values are:
+
+- callDescriptionNotAccepted, if the received call description was not accepted by the CC signalling service user. In this case an alternative call description may be returned together with the error value;
+- userBusy, if the called user is busy. In this case, if the received call description was not acceptable by the CC signalling service user, an alternative call description may be returned as additional information together with the error value;
+- unallocatedNumber, if the received call description contained an unallocated number;
+- noUserResponding, if the called user did not respond to the callEstablish invoke APDU;
+- noAnswerFromUser, if no answer from the called user to the callEstablish invoke APDU was received;
+- callRejected, if the called user rejected the call;
+- destinationOutOfOrder, if the called user's equipment is out of order;
+- addressIncomplete, if an address contained in the received call description was incomplete;
+- networkOutOfOrder, if equipment in the network is out of order;
+- temporaryFailure, if a temporary failure has occurred;
+- userNotReachable, if the called user is not reachable;
+- unspecified in any other case.
+
+When sending the callEstablish return error APDU, the Location parameter shall indicate the location at which the failure occurred. When an Error is first generated in a user's terminal, the location value "user" shall be used. When an Error is first generated in a network node, the location value "networkLocalCallSegment" shall be used. If that Error is passed on by a CC entity to another call segment, the value shall be changed to "networkNonLocalCallSegment".
+
+The callEstablish return error APDU may contain a Call Description element if provided by the CC signalling service user.
+
+NOTE – The call control signalling service user gives an indication to BC that the bearer connections for this call shall be cleared.
+
+Call establishment failure can also be indicated from the preceding CC entity to the succeeding CC entity while in state Await Call Completion by the use of the procedures for call clearing as defined in 9.7.
+
+## 9.7 Call clearing
+
+### 9.7.1 Procedures at the CC entity that initiates call clearing
+
+On receipt of a RELEASE-CALL request primitive from the call control signalling service user, the CC entity initiating call clearing shall send a callRelease invoke APDU, stop all timers, start timer T708, and enter the Call Release Request state.
+
+The argument of the callRelease invoke APDU shall contain a causeValue and the appropriate location parameter in element releaseCause. Valid cause values are "normalCallClearing", "callDescriptionNotAccepted", or "temporaryFailure", depending on the reason why the call control signalling service user initiates call clearing.
+
+Cause values shall be used as follows:
+
+- normalCallClearing, if call release was initiated by one of the involved users;
+- callDescriptionNotAccepted, if the received call description was not accepted by the CC signalling service user;
+- temporaryFailure, if a temporary failure has occurred.
+
+The location parameter shall indicate the location at which the failure occurred. When a releaseCause is first generated in a user's terminal, the location value "user" shall be used. When a releaseCause is first generated in a network node, the location value "networkLocalCallSegment" shall be used. If that releaseCause is passed on by a CC entity to another call segment the value shall be changed to "networkNonLocalCallSegment".
+
+The callRelease invoke APDU shall only be sent with a complete callSegmentId. Therefore, a CC entity which has initiated a call establishment, i.e. has sent a callEstablish invoke APDU, shall not initiate call clearing before either a callEstablish return result or callProceeding invoke APDU has been received.
+
+On receipt of the callRelease return result APDU while in state Call Release Request, the CC entity initiating clearing shall stop timer T708 and enter the Call Idle state.
+
+The receipt of the callRelease return result APDU is indicated to the call control signalling service user with a RELEASE-CALL confirm primitive.
+
+NOTE – When sending the RELEASE-CALL request primitive to the CC signalling service provider, the call control signalling service user also requests BC that the bearer connections for this call shall be cleared.
+
+### 9.7.2 Procedures at the CC entity that responds to clearing
+
+In any state except Call Idle, Call Release Request, and Call Release Indication the CC entity receiving a callRelease invoke APDU shall stop any timers that are running and enter the Call Release Indication state. The receipt of the callRelease invoke APDU is indicated to the call control signalling service user with a RELEASE-CALL indication primitive.
+
+On call control signalling service user request (RELEASE-CALL response primitive), the receiving CC entity shall send a callRelease return result APDU and return to the Call Idle state.
+
+NOTE – When receiving the RELEASE-CALL indication primitive, the call control signalling service user requests BC that the bearer connections for this call shall be cleared.
+
+### **9.7.3 Call clearing collision**
+
+In case of call clearing collision, i.e. on receipt of a callRelease invoke APDU while in state Call Release Request, the CC entity shall stop timer T708 and enter the Call Idle state.
+
+## **9.8 Exceptional procedures**
+
+### **9.8.1 Timer expiry**
+
+#### **9.8.1.1 Procedures at the preceding CC entity**
+
+If timer T703 expires, i.e. if no response to the callEstablish invoke APDU is received, the preceding CC entity shall clear the call internally, release the CallSegmentId, and enter the Call Idle state.
+
+Call clearing is indicated to the call control signalling service user by an ESTABLISH-CALL confirm primitive with negative Result parameter.
+
+If timer T710 expires, i.e. if a callProceeding invoke APDU has been received as a response to the callEstablish invoke APDU, but no callEstablish return result or return error APDU is received, the preceding CC entity shall clear the call by sending a callRelease invoke APDU, stop all timers, start timer T708, and enter the Call Release Request state. The callRelease invoke APDU sent to initiate call clearing shall contain causeValue "recovery on timer expiry" and an appropriate location value in element releaseCause.
+
+Call clearing is indicated to the call control signalling service user by an ESTABLISH-CALL confirm primitive with negative Result parameter.
+
+#### **9.8.1.2 Procedures at the succeeding CC entity**
+
+If timer T701 expires, i.e. if no callComplete invoke APDU is received in the Await Call Completion state, the succeeding CC entity shall clear the call internally, release the CallSegmentId, and enter the Call Idle state.
+
+This exceptional condition is indicated to the call control signalling service user by an ERROR indication primitive with an appropriate Diagnostics parameter.
+
+#### **9.8.1.3 Procedures at the CC entity that initiates call clearing**
+
+If timer T708 expires, i.e. if no response to the callRelease invoke APDU is received, the CC entity shall release the call segment ID and enter the Call Idle state.
+
+A RELEASE-CALL confirm primitive is given to the call control signalling service user if call clearing has been initiated on user request.
+
+### **9.8.2 Receipt of APDUs with unknown Call Segment Id**
+
+If an APDU other than a callEstablish invoke is received containing an unknown CallSegmentId, this APDU shall be ignored.
+
+### **9.8.3 Receipt of APDUs with duplicated Call Segment Id**
+
+If a callEstablish invoke APDU is received containing a CallSegmentId which is already in use, this APDU shall be ignored.
+
+### **9.8.4 Receipt of APDUs out of sequence**
+
+If an APDU out of sequence is received, i.e. a callProceeding invoke after a callEstablish return result, with the same CallSegmentId, this APDU shall be ignored.
+
+### **9.8.5 Receipt of reject APDUs**
+
+#### **9.8.5.1 Receipt of a reject APDU that is correlated to a callEstablish invoke**
+
+On receipt of a reject APDU that is correlated to a callEstablish invoke APDU while in state Call Initiated, the preceding CC entity shall stop timer T703, clear the call internally, release the CallSegmentId, and enter the Call Idle state.
+
+Call establishment failure is indicated to the call control signalling service user by an ESTABLISH-CALL confirm primitive with negative Result parameter.
+
+#### **9.8.5.2 Receipt of a reject APDU that is correlated to a callProceeding invoke**
+
+On receipt of a reject APDU that is correlated to a callProceeding invoke APDU while in state Incoming Call Proceeding, the succeeding CC entity shall remain in this state.
+
+This exceptional condition is indicated to the call control signalling service user by an ERROR indication primitive with an appropriate Diagnostics parameter.
+
+#### **9.8.5.3 Receipt of a reject APDU that is correlated to a callComplete invoke**
+
+On receipt of a reject APDU that is correlated to a callComplete invoke APDU while in state Call Active, the preceding CC entity shall clear the call by sending a callRelease invoke APDU, start timer T708, and enter the Call Release Request state. The callRelease invoke APDU sent to initiate call clearing shall contain causeValue "temporary failure" and an appropriate location value in element releaseCause.
+
+This exceptional condition is indicated to the call control signalling service user by an ERROR indication primitive with an appropriate Diagnostics parameter.
+
+#### **9.8.5.4 Receipt of a reject APDU that is correlated to a callStatus invoke**
+
+On receipt of a reject APDU that is correlated to a callStatus invoke APDU while in state Await Call Completion or Call Active, the CC entity shall remain in the same state.
+
+This exceptional condition is indicated to the call control signalling service user by an ERROR indication primitive with an appropriate Diagnostics parameter.
+
+#### **9.8.5.5 Receipt of a reject APDU that is correlated to a callRelease invoke**
+
+On receipt of a reject APDU that is correlated to a callRelease invoke APDU while in state Call Release Request, the CC entity shall stop timer T708, release the call segment ID, and enter the Call Idle state.
+
+A RELEASE-CALL confirm primitive is given to the call control signalling service user if call clearing has been initiated on user request.
+
+#### **9.8.5.6 Receipt of a reject APDU that is correlated to a callEstablish return result**
+
+On receipt of a reject APDU that is correlated to a callEstablish return result APDU while in state Call Active or Await Call Completion, the succeeding CC entity shall clear the call internally, release the CallSegmentId, and enter the Call Idle state.
+
+This exceptional condition is indicated to the call control signalling service user by an ERROR indication primitive with an appropriate Diagnostics parameter.
+
+#### **9.8.5.7 Receipt of a reject APDU that is correlated to a callEstablish return error**
+
+On receipt of a reject APDU that is correlated to a callEstablish return error APDU, no action shall be taken.
+
+#### 9.8.5.8 Receipt of a reject APDU that is correlated to a callRelease return result
+
+On receipt of a reject APDU that is correlated to a callRelease return result APDU, no action shall be taken.
+
+### 9.8.6 Handling of unrecognized parameters within CC-Operations
+
+On receipt of an APDU containing a CC-Operation with one or more unrecognized parameters, the receiving CC entity shall examine the parameterActionIndicator contained in this operation and follow the procedures described below as appropriate:
+
+- If the parameterActionIndicator is set to "clearCallAndItsInformationModel", the receiving CC entity shall clear the call and its information model in accordance with the procedures specified in 9.7.
+- If the parameterActionIndicator is set to "discardApduAndReject", the receiving CC entity shall discard the entire APDU and initiate sending of a reject APDU back to the peer CC entity.
+- If the parameterActionIndicator is set to "discardApduNoReject", the CC entity shall discard the entire APDU and not initiate sending of a reject APDU.
+- If the parameterActionIndicator is set to "discardParameterAndPassApduToApplication", the receiving CC entity shall discard the unrecognized parameter and pass the APDU without the unrecognized parameter on to the CC signalling service user.
+- If the parameterActionIndicator is set to "ignoreParameterAndPassApduToApplication", the receiving CC entity shall ignore the unrecognized parameter and pass the APDU including the unrecognized parameter on to the CC signalling service user.

+
+# 11 Transport mechanism
+
+The design of this protocol does not demand for a special transport mechanism. However, a reliable transport mechanism is required.
+
+Transport mechanisms which can be used are listed in Annex D. Subclauses Annex D for the various transport mechanisms specify how a particular mechanism shall be used if it has been chosen.
+
+NOTE – Annex D is normative but not exclusive, i.e. other reliable transport mechanisms which are not mentioned there can be used as well.

+The diagrams represent the behaviour of the CC signalling service provider, which is split into outgoing CC-ASE and incoming CC-ASE (Application Service Element).
+
+Input signals from the left and output signals to the left represent primitives to and from the CC signalling service user. Also protocol timer expiry is indicated by an input signal from the left.
+
+Input signals from the right and output signals to the right represent APDUs sent to and received from the peer CC entity.

From **Call\_Idle**, a transition labeled **EST-CALL req.** leads to a state labeled **store await complete indicator**. This is followed by a transition labeled **start timer T703** to a state labeled **callEstablish inv.**, which finally leads to the **Call\_Initiated** state.

+## Bearer coordination requirements for CC signalling service users
+
+Signalling for bearer control is outside the scope of this Recommendation. The way in which a CC entity coordinates the call's bearers is also outside the scope of this Recommendation, except that the following requirements shall be met.
+
+### A.1 Requirements at a CC entity that establishes a bearer towards an adjacent CC entity
+
+The requirements in this subclause apply to an end CC entity that initiates bearer establishment towards the adjacent CC entity on request of the application. An end CC entity can be an originating CC entity that initiates bearer establishment in the forward direction (with respect to the direction of call establishment) or a terminating CC entity that initiates bearer establishment in the backward direction (with respect to the direction of call establishment).
+
+The requirements in this subclause also apply to a transit CC entity that continues bearer establishment towards the subsequent CC entity following receipt of an incoming bearer from the preceding CC entity (such a bearer being in the forward direction with respect to the direction of call establishment), or that continues bearer establishment towards the preceding CC entity following receipt of an incoming bearer from the subsequent CC entity (such a bearer being in the backward direction with respect to the direction of call establishment).
+
+Bearer establishment in the forward direction shall not commence before one of the following APDUs has been received from the subsequent CC entity:
+
+- callProceeding invoke APDU; or
+- callEstablish return result APDU.
+
+The contents of elements *bearerEstablishmentAddress* and *callSegmentId* in the first of the above APDUs to be received shall be used as the destination address and the call segment identifier respectively for bearer establishment.
+
+NOTE 1 – Omission of either of these elements from the first of these APDUs constitutes a protocol error.
+
+Bearer establishment in the backward direction shall not commence before one of the following APDUs has been sent to the preceding CC entity:
+
+- callProceeding invoke APDU; or
+- callEstablish return result APDU.
+
+The contents of element *callSegmentId* in the first of the above APDUs to be transmitted and element *bearerEstablishmentAddress* in the received *callEstablish invoke* APDU shall be used as the call segment identifier and the destination address respectively for bearer establishment.
+
+NOTE 2 – For bearer establishment in either direction, the value used for the bearer destination address will cause the bearer to be routed to the terminal or network node where the CC entity at the opposite end of the call segment is located.
+
+NOTE 3 – For bearer establishment in either direction, the call segment identifier is conveyed transparently by bearer control signalling to the terminal or network node where the CC entity at the opposite end of the call segment is located, thereby allowing that terminal or network node to link the bearer to the call.
+
+NOTE 4 – Call control signalling service users should ensure that bearer connection elements established by associated bearer control prior to call acceptance are consistent with all variants of selectable options within the call description included in the call establishment request. After call establishment call control entities should ensure that bearer connection elements are consistent with the final call description. Bearer connection elements and bearer connection establishment requests failing these criteria should be rejected or released as appropriate.
+
+For bearer establishment in either direction, an address representing the local CC entity (i.e. the CC entity at the start of the segment) shall be used as the calling address of the bearer.
+
+For bearer establishment in either direction, a bearer identifier value by which the bearer is to be known by the two CC entities at either end of the call segment may be provided as part of the bearer establishment request. The bearer identifier value shall have significance across the call segment concerned.
+
+NOTE 5 – For bearer establishment in either direction, the bearer identifier value, if provided in the bearer establishment request, is conveyed transparently by bearer control signalling to the terminal or network node where the CC entity at the opposite end of the call segment is located. Its purpose is to allow that CC entity to associate the bearer establishment with a bearer reference conveyed within call control signalling (e.g. as an attribute of an Attachment object). If call control signalling has already made reference to this bearer, prior to its establishment, the bearer identifier value used in the bearer establishment request should be the same as the bearer reference already used by call control signalling. Any further call control signalling that needs to refer to this bearer should use the bearer identifier value used in the bearer establishment request.
+
+Bearer establishment shall not commence after a callRelease invoke APDU has been sent or received across the segment concerned.
+
+### **A.2 Requirements at a CC entity that receives a bearer establishment from an adjacent CC entity**
+
+The requirements in this subclause apply to a CC entity that receives an incoming bearer establishment from an adjacent CC entity. This can be from the preceding CC entity (in the case of a bearer established in the forward direction with respect to the direction of call establishment) or from the subsequent CC entity (in the case of a bearer established in the backward direction with respect to the direction of call establishment).
+
+A terminal or network node that receives an incoming bearer establishment signal containing a destination address that indicates that that terminal or network node is the destination of the bearer shall attempt to match the received call segment identifier with a call segment identifier assigned to a call segment that is associated with a CC entity on that terminal or network node. If a match is found, the CC entity concerned shall proceed with establishment of the bearer.
+
+NOTE 1 – In the case of a transit CC, the time at which bearer establishment is continued across the next call segment is outside the scope of this Recommendation, apart from being subject to the restrictions in A.1.
+
+NOTE 2 – In the case of an end CC, the bearer should be presented to the application.
+
+NOTE 3 – Call control signalling service users should ensure that bearer connection elements established by associated bearer control prior to call acceptance are consistent with all variants of selectable options within the call description included in the call establishment request. After call establishment call control entities should ensure that bearer connection elements are consistent with the final call description. Bearer connection elements and bearer connection establishment requests failing these criteria should be rejected or released as appropriate.
+
+If the terminal or network node is the destination of the bearer but is unable to match the received call segment identifier with a call segment identifier assigned to a call segment that is associated with a CC entity on that terminal or network node, the terminal or network node shall reject the bearer establishment request.
+
+Even though a succeeding CC entity is required to send a callProceeding invoke APDU or callEstablish return result APDU before commencing bearer establishment in the backward direction, it is possible for a bearer establishment request to arrive at a preceding CC entity before any of the above APDUs arrives. In this case, the preceding CC shall await the arrival of one of the above APDUs before continuing to process the bearer establishment request. If timer T703 expires, the bearer establishment request shall be released.
+
+NOTE 4 – If the received bearer establishment request contains a bearer identifier value, this value should be used by the CC entity in any future call control signalling relating to this bearer. If call control signalling has already made reference to this bearer, prior to its establishment, using this value, the incoming bearer establishment request should be associated with that bearer reference.
+
+### **A.3 Additional requirements at a transit CC**
+
+A transit CC shall relay an alerting or answer indication from the outgoing bearer on to the incoming bearer.
+
+A transit CC shall relay a release indication from either bearer on to the other bearer, except that a release indication from an outgoing bearer that is in the bearer establishment phase may instead, depending on the cause of release, result in re-routing of the outgoing bearer.
+
+A transit CC shall pass on any subaddress information from one bearer unchanged to the other bearer.
+
+A transit CC shall pass on any low layer or high layer compatibility information (e.g. Q.2931 B-HLI, B-LLI, N-HLC, N-LLC or N-BC information elements) from one bearer unchanged to the other bearer.
+
+A transit CC shall pass on any bearer-related supplementary service information from one bearer, unless acted upon at the network node concerned, unchanged to the other bearer.
+
+### **A.4 Requirement on call clearing**
+
+On sending or receiving a callRelease invoke APDU across a call segment, the CC entity shall immediately initiate the release of any bearers across that call segment that are not already in the process of being released.
+
+# **ANNEX B**
+
+## **Call description handling requirements for CC signalling service users**
+
+## **B.1 Call description handling at a CC signalling service user within an originating CC entity**
+
+When requesting the CC signalling service provider to send a callEstablish invoke APDU, a CC signalling service user within an originating CC shall include a call description containing the following objects:
+
+Network relevant objects:
+
+- one Call object, with status mandatory;
+- two Call Party End Point objects, one indicated in the Call object as local and identifying the local user, the other indicated in the Call object as remote, and both with status mandatory;
+- one Call Party End Point Association object referencing the two Call Party End Point objects, with status conditional;
+- optionally one or more Service Component objects, each with status either mandatory or optional.
+
+End-to-end relevant objects:
+
+- for each Service Component object, two Participation objects (one per Call Party End Point object), each with status conditional.
+
+### **B.2 Call description handling at a CC signalling service user within a transit CC entity**
+
+A CC signalling service user within a transit CC may modify the network relevant objects contained in a call description received in a callEstablish invoke APDU prior to requesting the CC signalling service provider to pass it on in a callEstablish invoke APDU towards the next CC. Modification shall be limited to the following:
+
+- the removal of one or more objects with status optional; and
+- the removal of any objects with status conditional that depend on other objects removed.
+
+NOTE 1 – This means, for example, that objects cannot be added, objects with status mandatory cannot be deleted, and object attributes cannot be modified.
+
+If a CC signalling service user within a transit CC is unable to accept the network relevant objects contained in the call description as received and is unable to achieve an acceptable call description by means of modification in accordance with the rules above, it shall reject the call with an appropriate error value, e.g. callDescriptionNotAccepted.
+
+NOTE 2 – A return error APDU with error value callDescriptionNotAccepted can contain an alternative call description that would be acceptable to the CC signalling service user.
+
+A CC signalling service user within a transit CC shall not modify a call description passed on in any other APDU (i.e. callEstablish return result or callEstablish return error), nor the callChangedParameter in a callStatus invoke APDU.
+
+A CC signalling service user within a transit CC shall pass on transparently the end-to-end relevant objects contained in a call description received in a callEstablish invoke APDU.
+
+### **B.3 Call description handling at a CC signalling service user within a terminating CC entity**
+
+A CC signalling service user within a terminating CC may modify the end-to-end and network relevant objects contained in call description received in a callEstablish invoke APDU prior to requesting the CC signalling service provider to send back a callEstablish return result APDU. Modification shall be limited to the following:
+
+- the removal of one or more objects with status optional; and
+- the removal of any objects with status conditional that depend on other objects removed.
+
+NOTE 1 – This means, for example, that objects cannot be added, objects with status mandatory cannot be deleted, and object attributes cannot be modified.
+
+If a CC signalling service user within a terminating CC is unable to accept the call description as received and is unable to achieve an acceptable call description by means of modification in accordance with the rules above, it shall reject the call with an appropriate error value, e.g. callDescriptionNotAccepted, userBusy, callRejected.
+
+NOTE 2 – A return error APDU with error value callDescriptionNotAccepted or userBusy can contain an alternative call description that would be acceptable to the CC signalling service user.
+
+NOTE 3 – One reason for a received call description being unacceptable is that it has been sent by equipment that supports enhanced capabilities beyond the scope of this Recommendation and therefore contains additional objects (e.g. more than two Party End Point objects).
+
+### **B.4 Call description errors**
+
+When a call description parameter is received which has one or more unexpected object identifiers or object identifiers with unrecognized attributes (arguments), the receiving entity shall examine the object action indicator, and follow the procedures described in a), b), c), d) or e) below as appropriate.
+
+If more than one object identifiers and/or object attributes are received in error, only one response shall be given. The response shall be according to the handling of the object action indicator attribute according to the following order of priority: "clearCall" (highest priority), "discardNotify", "discardUnknown", "progressTransit".
+
+#### a) *Object action indicator attribute = clearCall*
+
+If the object action indicator attribute is equal to "clear call object model", the call shall be cleared according to the procedures defined in 9.7 except that the Cause information element shall contain the cause "call DescriptionNotAccepted".
+
+#### b) *If the object action indicator attribute = discardNotify*
+
+The call description shall be ignored and a *returnError* APDU with error value "callDescriptionNotAccepted" shall be returned.
+
+#### c) *Object action indicator attribute = discardUnknown*
+
+If the object action indicator attribute is equal to "discard unknown item and proceed", the unknown item (either the entire object or only the unknown attribute) shall be ignored and the call description shall be processed as if the unknown information was not received. No *returnError* APDU shall be sent.
+
+#### d) *Object action indicator attribute = progressTransit*
+
+The unknown object or unknown attribute shall be progressed as an octet string parameter to succeeding call control (if the operation requires so), but shall not be retained by the call control service user once the operation is complete.
+
+#### e) *Object action indicator attribute = unknown value*
+
+If an unknown object or unknown attribute has an associated object action indicator that contains an unknown value, then the receiver shall handle the call description as if the object action indicator attribute had been set to "progressTransit".
+
+### **B.5 End-to-end relevant object handling at a CC signalling service user within a transit CC entity**
+
+End-to-end relevant objects (service components) shall always be handled by a CC signalling service user within a transit CC entity as unknown objects with an object action indicator attribute set to "progressTransit", regardless of the value that the object action indicator attribute is actually set to. The operation shall always be progressed when this type of object is the only unknown error.
+
+## **B.6 Changes to the Information Model**
+
+The Call Control protocol provides a single mechanism to indicate changes to the information model, the Status Call procedure. This procedure provides for a single unconfirmed flow and therefore represents only non-negotiable changes that reflect events that have already happened. The changes to the information model that the CC signalling service user shall indicate using this procedure are:
+
+- addition and deletion of a service component object;
+- changes to the attributes of a party object (i.e. modification of the status of a party);
+- changes to the OpenCall attribute of the call object (i.e. modification of the call permissions).
+
+#### **B.6.1 Deletion of a Service Component Object**
+
+The deletion of a service component reflects the ability of any user application to discontinue using some portion of an implementation's functionality. Any CC signalling service user at an originating or terminating CC entity can delete a service component in the information model. An attempt to
+
+delete a service component that does not exist shall not cause an error, but shall be ignored by the CC signalling service user at the peer originating or terminating CC entity.
+
+#### **B.6.2 Addition of a Service Component Object**
+
+The addition of a service component using the Status Call procedure reflects the ability of an originating or terminating CC entity to begin using some portion of an implementation's functionality. The Status Call procedure does not support either confirmation or negotiation of this functionality and so it is assumed that this does not place any additional requirements on the bearer. The CC signalling service user at the peer originating or terminating CC entity, receiving an indication of an added service component, may choose to ignore the indication.
+
+### **B.6.3 Changes to the attributes of the Party Object**
+
+The changes to the attributes of a party object that the CC signalling service user shall indicate are:
+
+- changes to the status of a party (e.g. alerting);
+- changes to the type of a party.
+
+The procedures associated with the status call require that the complete party object shall be provided.
+
+#### **B.6.4 Changes to the Open Call attribute of the Call Object**
+
+The OpenCall attribute of the call object defines the rights of parties to modify the call by the addition of parties, connections or service components. The permissions provide the requirements for notification and requesting call owner permission.
+
+The OpenCall parameter contains the following Boolean indications which shall take the values shown:
+
+- externalPartyAddAllowed:  
+Value: False.  
+Usage: Indicates that another party, not currently part of the call, shall not join the call configuration.
+- existingPartyAddAllowed:  
+Value: False.  
+Usage: Indicates that a non-call owner party shall not introduce another party, not currently part of the configuration, into the call.
+- notifyAllPartiesFlag:  
+Value: True.  
+Usage: Indicates whether a party successfully joining the call is required to be notified to all the existing members of the call. This indication is provided for future capability and is not currently used. It shall be set to true as this is more restrictive.
+- notifyOwnerFlag:  
+Value: True.  
+Usage: Indicates whether a party successfully joining the call is required to be notified to the call owner. This indication is provided for future capability and is not currently used. It shall be set to true as this is more restrictive.
+
+– permissionRequiredFlag:
+
+Value: True.
+
+Usage: Indicates whether a party may join the call only after the call owners permission has been sought. This indication is provided for future capability and is not currently used. It is shall be set to true as this is more restrictive.
+
+– addConnectionAllowed:
+
+Value: True or False.
+
+Usage: Indicates whether the non-call owner is permitted to add a connection to an existing call. If the value is set to true then any party may add a connection and also the CC signalling service provider shall refuse any request to change this value from true to false. A change from false to true is permitted.
+
+– addServiceComponentAllowed:
+
+Value: True or False.
+
+Usage: Indicates whether the non-call owner is permitted to add a service component to an existing call. If the value is set to true then any party may add a service component to a connection. The CC signalling service provider shall refuse any request to change this value from true to false. A change from false to true is permitted.
+
+The call permissions are indicated to the non-call owner as part of the call description during call establishment. The call permissions are not a subject for negotiation and shall not be changed by any CC signalling service user except the call owner CC signalling service user.
+
+Changes to the call permissions that reduce or restrict the modification rights of non-call owners can result in conflicts. To prevent protocol clashes, any call control protocol service provider shall refuse to accept a request by a CC signalling service user to alter the OpenCall parameter if such an alteration removes a capability already granted. A refusal shall result in the changes to the OpenCall attribute of the call object being ignored and not being passed on to any succeeding CC signalling service user.
+
+A CC signalling service user that receives a STATUS-CALL indication primitive that alters the call modification permission shall store the new permissions and pass on unchanged the OpenCall parameter towards the next CC using the STATUS-CALL request.
+
+The CC signalling service user that initiated the call may allow another party to add either connections or service components at call establishment by initiating a call with either the addConnectionAllowed flag set to TRUE or the addServiceComponentAllowed flag to TRUE or both. The CC signalling service user that initiated the call may change the permissions to allow another party to add either connections or service components after call establishment using the call status procedure to change either of the above flags from false to true. The call status procedure shall not be used to change either of the flags from TRUE to FALSE. The call status procedure shall not be used to change any of the other flags in the OpenCall parameter.
+
+# ANNEX C
+
+## Interworking
+
+Interworking occurs with other networks, which do not support the separation of Call Control and Bearer Control or which send simultaneous call and bearer establishment requests.
+
+Interworking with such networks requires both Call Control and Bearer Control functions in the gateway node at the boundary to these networks.
+
+The interworking is performed by the CC signalling service user of the Call Control entity in the gateway node.
+
+## **C.1 Interworking with networks not supporting separation of Call Control and Bearer Control**
+
+### **C.1.1 Outgoing call establishment**
+
+In case of an outgoing call establishment to a network which does not support the separation of Call Control and Bearer Control, the Call Control entity in the gateway node shall act as the terminating CC entity for that call. When the call establishment has been accepted by the terminating CC entity in the gateway node, subsequent bearer establishment requests which match with that call shall be forwarded to the other network.
+
+### **C.1.2 Incoming bearer establishment**
+
+In case of an incoming bearer establishment from a network which does not support the separation of Call Control and Bearer Control, the establishment can optionally be progressed in accordance with this Recommendation. In this case the Call Control entity in the gateway node shall act as the originating CC entity and initiate establishment of a call, that matches with the required bearer. When the call establishment has been accepted, i.e. after receipt of a callProceeding invoke APDU or callEstablish return result APDU, the bearer establishment shall be progressed.
+
+### **C.1.3 Addition of bearers to an existing call**
+
+When a call exists between an originating CC entity and the CC entity in a gateway node to a network which does not support the separation of Call Control and Bearer Control, and a bearer has to be added to that call, the decision as to whether or not the additional bearer is supported is not taken in the gateway, but another bearer establishment shall be made across the other network to the same addressed terminal.
+
+## **C.2 Interworking with simultaneous call and bearer establishment**
+
+In this case of interworking the other network supports the separation of Call Control and Bearer Control but only the capability of simultaneous establishment of a call with one bearer is supported.
+
+### **C.2.1 Outgoing call establishment**
+
+In case of an outgoing call establishment to a network which only supports simultaneous call and bearer establishment, the Call Control entity in the gateway node shall act as the terminating CC entity for that call. When the call establishment has been accepted by the terminating CC entity in the gateway node and when a subsequent bearer establishment request belonging to that call is received, a simultaneous call and bearer establishment shall be initiated towards the other network.
+
+### **C.2.2 Incoming call and bearer establishment**
+
+In case of an incoming call and bearer establishment, the Call Control entity in the gateway node shall act as the originating CC entity and initiate separate establishment of a corresponding call. When the call establishment has been accepted, i.e. after receipt of a callProceeding invoke APDU or callEstablish return result APDU, the bearer establishment shall be progressed.
+
+### **C.2.3 Addition of bearers to an existing call**
+
+When a call exists between a CC entity and the CC entity in a gateway node to a network which only supports simultaneous call and bearer establishment, and a bearer in outgoing direction has to be added to that call, the decision as to whether or not the additional bearer is supported is not taken in the gateway, but another bearer establishment shall be made across the other network to the same addressed terminal. If a bearer in incoming direction has to be added to that call, i.e. if an incoming bearer establishment is received, the gateway shall forward it to the corresponding destination.

+# **ANNEX D**
+
+## **Transport mechanisms**
+
+This annex lists transport mechanisms which can be used with the call control protocol and specifies how to use them.
+
+NOTE – This annex is normative but not exclusive, i.e. other reliable transport mechanisms which are not mentioned here can be used as well.
+
+## **D.1 Connection oriented-Bearer independent**
+
+The connection oriented-bearer independent (CO-BI) transport mechanism is specified in ITU-T Recommendation Q.2932.1 [8] for the S<sub>B</sub> and coincident S<sub>B</sub>/T<sub>B</sub> reference point. If the CO-BI transport mechanism is chosen, the following shall apply:
+
+- The operations defined in 8.1 shall be coded in the Facility information element in accordance with ITU-T Recommendation Q.2932.1 [8].
+- The instruction indicator in the Facility information element shall be coded in accordance with ITU-T Recommendation Q.2932.1 [8].
+- The Facility information element shall be conveyed in the messages for the CO-BI transport mechanism as specified in ITU-T Recommendation Q.2932.1 [8].
+- The instruction indicator in the messages for the CO-BI transport mechanism shall be coded in accordance with ITU-T Recommendation Q.2932.1 [8].
+
+Additionally for the Q<sub>B</sub> reference point:
+
+- When conveying the invoke APDU of operations defined in 8.1, the NFE (Network Facility Extension) shall either be omitted or be included.
+- When conveying the invoke APDU of operations defined in 8.1, the Interpretation APDU shall either be omitted or be included].
+
+## **D.2 Connectionless-Bearer independent**
+
+The connectionless-bearer independent (CL-BI) transport mechanism is specified in ITU-T Recommendation Q.2932.1 [8] for the S<sub>B</sub> and coincident S<sub>B</sub>/T<sub>B</sub> reference point. If the CL-BI transport mechanism is chosen, the following shall apply:
+
+- The operations defined in 8.1 shall be coded in the Facility information element in accordance with ITU-T Recommendation Q.2932.1 [8].
+
+- The instruction indicator in the Facility information element shall be coded in accordance with ITU-T Recommendation Q.2932.1 [8].
+- The Facility information element shall be conveyed in the FACILITY message for the CL-BI transport mechanism as specified in ITU-T Recommendation Q.2932.1 [8].
+- The instruction indicator in the FACILITY message for the CL-BI transport mechanism shall be coded in accordance with ITU-T Recommendation Q.2932.1 [8].
+
+Additionally for the Q<sub>B</sub> reference point:
+
+- When conveying the invoke APDU of operations defined in 8.1, the NFE (Network Facility Extension) shall either be omitted or be included.
+- When conveying the invoke APDU of operations defined in 8.1, the Interpretation APDU shall either be omitted or be included.

The sequence starts with the Originating CC sending an EST-CALL req to the first Transit CC. The first Transit CC forwards the callEstablish inv. to the second Transit CC, which then forwards it to the Terminating CC. The Terminating CC responds with EST-CALL resp, which is forwarded back through the Transit CCs to the Originating CC. The Originating CC then sends a COMP-CALL req, which is forwarded through the Transit CCs to the Terminating CC. The Terminating CC responds with COMP-CALL ind. The diagram also shows various intermediate states and messages like PROC-CALL req, callProceeding inv., and callComplete inv. that occur during the establishment process.

+
+## **Summary**
+
+Recommendation ITU-T Q.3030 describes the overall signalling architecture for the NGN service control plane including the functional entities, interfaces and protocols.
+
+### **Source**
+
+Recommendation ITU-T Q.3030 was approved on 29 February 2008 by ITU-T Study Group 11 (2005-2008) under Recommendation ITU-T A.8 procedure.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 6 Service control functions
+
+The service control functions include call/session control, resource control, registration, and authentication and authorization functions at the service level for both mediated and non-mediated
+
+services. They may also include functions for controlling media resources, i.e., specialized resources and gateways at the service-signalling level.
+
+# **7 Service control architecture and interfaces**
+
+This clause describes the details of the signalling architecture for the NGN service control plane, including the functional entities, interfaces and protocols. This service control architecture supports SIP-based sessions and is independent of services.
+
+Figure 1 shows the generalized NGN functional architecture as defined in [ITU-T Y.2012]. The service control functional entities are bordered (highlighted) in Figure 1. The signalling architecture for the NGN service control plane is based on the service control functions outlined in clause 6.

+#### **7.3.26 A-S1: S-14 (MRB-FE) – ASF/SSF**
+
+This reference point is used for MRB-FE to assign specific media server resources (i.e., MRC-FE and MRP-FE) to incoming calls at the request of service applications of the ASF/SSF.
+
+Interfaces supporting the above reference point could use SIP, HTTP, SOAP.
+
+#### **7.3.27 A-S4: S-1 (S-CSC-FE) – ASF/SSF**
+
+This reference point supports the interactions between the S-CSC-FE and ASF/SSF in order to provide various session-based application services.
+
+ASF/SSF may interact with the AGC-FE through the S-CSC-FE to provide access to the applications required to support the legacy terminal users.
+
+Interfaces supporting the above reference point will use SIP.
+
+#### **7.3.28 A-S5: S-6 (SAA-FE) – ASF/SSF**
+
+This reference point allows the ASF/SSF to query the SAA-FE the status of authentication, authorization, and accounting of users/terminals while it provides services.
+
+Interfaces supporting the above reference point will use the Diameter (\*) protocol.
+
+\*Whether other protocols may also be used need to be discussed as ITU-T has not agreed on a protocol for this reference point so far.
+
+#### **7.3.29 A-S6: S-4 (SL-FE), S-5 (SUP-FE) – ASF/SSF**
+
+This reference point allows the ASF/SSF to query subscriber's service profile and/or on the terminal capability information directly from SUP-FE, or indirectly from SUP-FE through SL-FE in case of multiple SUP-FEs.
+
+Interfaces supporting the above reference point will use the Diameter (\*) protocol.
+
+\* Whether other protocols may also be used need to be discussed as ITU-T has not agreed on a protocol for this reference point so far.
+
+#### **7.3.30 S-13 (MRC-FE) – Application support function (ASF)**
+
+This reference point enables the MRC-FE to interact with the ASF for enhanced services information, e.g., announcement.
+
+There are multiple protocols/languages and modes of transport options for interfaces supporting this reference point. A particular network provider's service types, equipment, traffic volumes, resource sharing strategies, etc., would determine the particular S-13 (MRC-FE) – ASF interface best options for that network. More than one control protocol/language can be used for the interactive media functionality. Example control protocols/languages for this interface include SIP, HTTP, voice extensible markup language (VoiceXML) and media server control markup language (MSCML).

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+

+# **Introduction**
+
+The service control functions include call/session control, resource control, registration, and authentication and authorization functions at the service level for both mediated and non-mediated services. They may also include functions for controlling media resources, i.e., specialized resources and gateways at the service-signalling level. Recommendation ITU-T Q.3040 describes the overall signalling architecture for the IPTV control plane. It identifies the functions, functional blocks, physical entities, interfaces, and protocols that will model the control plane for IPTV.
+
+## Recommendation ITU-T Q.3040
+
+# Signalling architecture for IPTV control plane
+
+# 1 Scope
+
+This Recommendation describes the overall signalling architecture for IPTV control plane. It identifies the functions, functional blocks, physical entities, interfaces, and protocols that will model the control plane for IPTV.
+
+The interfaces identified in this Recommendation include:
+
+- interfaces between the service control entities and the IPTV application entities;
+- interfaces between the service control entities and the control entities of service transport stratum;
+- interfaces between the service control entities and the content delivery entities;
+- interfaces between the service control entities and the end user.
+
+Other interfaces (such as the interfaces between two IPTV application entities, internal interfaces of service transport stratum, etc.) are outside the scope of this Recommendation.
+
+Appendix I provides functions and reference architecture of non-NGN IPTV architecture which are extracted from [ITU-T Y.1910]. This includes the reference points related and unrelated to service control functions, which may be helpful for the readers.

+# 7 Physical entities and interfaces in IPTV architecture
+
+When implementing an IPTV architecture, some of the functional entities identified in clause 6 may be grouped and implemented in a number of physical entities. Figures 7-1 and 7-2 provide examples of how the functional entities could be grouped for both an IMS and non-IMS based NGN. These architectures are used to identify the signalling interfaces that are within the scope of this Recommendation.

+
+## **8.2 Interfaces in NGN IMS IPTV architecture**
+
+The interfaces below are in the NGN IMS IPTV architecture which is depicted in Figure 7-2.
+
+### **8.2.1 Interface Is-a**
+
+For NGN IMS IPTV architecture, interface Is-a will use SIP as per [b-ETSI TS 124 229], as indicated in [ITU-T Q.1741.6].

+
+For NGN IMS IPTV architecture, interface Is-e will use SIP as per [b-ETSI TS 124 229], as indicated in [ITU-T Q.1741.6].
+
+NOTE – Is-e interface relates to UNI defined by [b-ITU-T Q.3402]; however, IPTV services are not covered by [b-ITU-T Q.3402]. The relationship is for further study.
+
+### **8.2.3 Interface Is-c**

+# Recommendation ITU-T Q.3203
+
+## Signalling requirements and architecture of network attachment control functions to support IP mobility
+
+## Summary
+
+The addition of IP mobility in access networks impacts the functionality of network attachment control functions (NACF), and raises additional signalling requirements of NACF with respect to the mechanism of IP address management and the signalling flows for mobility interface. Recommendation ITU-T Q.3203 proposes the generic signalling requirements and architecture for NACF functionality defined in Recommendation ITU-T Y.2014, with considerations of interfacing the mobility management functions described in Recommendation ITU-T Y.2018.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+## Recommendation ITU-T Q.3203
+
+## Signalling requirements and architecture of network attachment control functions to support IP mobility
+
+# 1 Scope
+
+This Recommendation describes signalling architecture and relevant interfaces of network attachment control functions (NACF) to support IP mobility in access networks, considering interaction with signalling and functionality of mobility management and control functions (MMCF) defined in [ITU-T Y.2018]. Additional signalling requirements of NACF are identified to support IP mobility in next generation access (NGA) networks, with respect to the mechanism of IP address management and the signalling flows for mobility interface. This Recommendation addresses the signalling requirements and architecture of NACF for mobility service based on [ITU-T Y.2014]. Mobility signalling of other functions (such as MMCF and resource and admission control functions (RACF)) is out of the scope of this Recommendation.

+# 6 Overview of protocol supporting IP mobility on the NGN access network
+
+This Recommendation describes the signalling requirements and architecture of the network attachment control function (NACF) for both host- and network-based mobility management that rely on the signalling and functionality of the mobility management and control function (MMCF) added to support mobility management in the next generation network (NGN) transport stratum. NACF gives information about mobility management to MMCF, which is responsible for mobile location management and handover control.
+
+In the IETF-based network architecture, two entities are generally considered to support IP mobility: a home agent (HA) and an access gateway. The home agent manages IP addresses in addition to mobile-user profiles, and it delivers packets to mobile nodes (MN). In the case of network-based mobility management, the access gateway detects a user's movement to a new network and registers the user's care of address (CoA) with the HA. This approach does not require any additional protocol for the MN to support IP mobility. However, in the case of host-based mobility management, users have to configure their new CoA. Whenever a user moves to a new network, the user configures its CoA and then registers it with the home agent. Appendix I describes the network architecture based on IETF mobile protocols.
+
+The NGN mobility architecture, including components of NACF and MMCF, possibly applies to the general mobility architecture. In the NGN architecture model, NACF is responsible for allocating the IP address and performing authentication. NACF allocates two kinds of IP addresses: a persistent IP address (PIA) and a temporary IP address (TIA), and updates the UE's temporary IP address with the MMCF for mobility service. The NACF can optionally perform an authentication process when the UE changes network.
+
+## 6.1 Network architecture
+
+The MMCF defined in [ITU-T Y.2018] is required for mobility service in the NGN transport stratum [ITU-T Q.1707]. Also, mobility-specific transport functions are needed in the forwarding plane of the transport stratum, as shown in Figure 6.1. In the control plane, NACF has interaction with MMCF to transfer mobility service parameters.

+
+## 6.2 Host configuration
+
+The UE initially sets its persistent IP address (PIA) with either a stateless or a stateful configuration. When using a stateless configuration, known as autoconfiguration based on [IETF RFC 4862], the UE builds an EUI-64-formatted IPv6 address using a network prefix contained in router advertisements (RAs) from transport function. In a stateful configuration, the IP address for PIA is obtained from a DHCP server. When an attachment between NACF and the mobile UE initially occurs, its PIA configuration is executed. Once a mobile UE has configured its IP address, it maintains its IP address within a home-agent domain. In the case of host-based mobility, the mobile node has to configure its temporary IP address (TIA) in addition to its PIA, while in the case of network-based mobility, the mobile node has its PIA maintained as user profile information. Whenever the mobile node is attached to a different access network, the mobile UE configures its TIA in a stateful or stateless manner (see clause 7.3.1).
+
+During the attachment process, mobility authentication is also performed between the mobile UE and the NACF. Either the pre-authentication or the re-authentication method may be used to reduce authentication latency. In a host-based mobility case, the information derived from the UE authentication process is transferred from NACF to MMCF. Otherwise, NACF indicates the network-based mobility service to MMCF.
+
+## 6.3 Handover management
+
+The MMCF has handover control functions (HCFs) which provide session continuity for the mobile UE's sessions. The HCF concentrates on minimizing data loss and handover latency during the UE's movement. Also, the forwarding plane of the transport stratum performs the handover execution function to support IP mobility.
+
+# 7 Mobility signalling requirements of NACF
+
+## 7.1 Data structure
+
+The mobility service parameters required to extend NACF for IP mobility are defined in [ITU-T Y.2014]; mobility service parameters consist of MLM-FEs' addresses, keying material, mobility protocol type (e.g., host-based or network-based mobility), an optional anchor point address, and an optional tunnel end point address.
+
+In the access authentication procedure, shown in Figure 7, AM-FE obtains an identifier from a UE and requests a mobile UE's authentication to TAA-FE. TAA-FE receives the mobile UE's policy profile from TUP-FE through Nb reference point. A user profile may be downloaded from
+
+the TAA-FE server in the home NGN network to the TAA-FE proxy in the visited NGN network. The TAA-FE responds to the AM-FE with the mobile node's policy profile. User data related to network location information in the policy profile may be transferred between TAA-FE and TLM-FE via the Nc reference point.
+
+![Sequence diagram showing NACF information flow for access authentication. The diagram involves five entities: AM-FE, TAA-FE proxy, TLM-FE, TAA-FE server, and TUP-FE. The sequence of messages is: 1. AM-FE sends an AAA request (MN-ID) to TAA-FE proxy. 2. TAA-FE proxy sends an AAA reply + policy profile to AM-FE. 3. TAA-FE proxy sends network location information to TLM-FE. There are also internal messages between TAA-FE server and TUP-FE, and between TAA-FE proxy and TAA-FE server.

+
+**Figure 7 – NACF information flow for access authentication**
+
+## 7.2 Movement detection
+
+Handover decision can be made by either the mobile node or the handover decision and control functional entity (HDC-FE) in MMCF. After the network attachment point is determined, the mobile node performs authentication for the target access network. When a user attaches to the target network, AM-FE forwards the user's authentication request to TAA-FE.
+
+NACF may provide pre-authentication and re-authentication to reduce the handover latency. The user transport profile and mobility service parameters are sent from the TAA-FE in the home network to the TAA-FE in the target network. The mobility service parameters include the UE's PIA and the address of the MLM-FE (C). TAA-FE delivers mobility service parameters, including the keying material used between the mobile user and the MLM-FE (P), to TLM-FE.
+
+## 7.3 Location registration
+
+### 7.3.1 IP address allocation
+
+During the authentication procedure, TAA-FE may request an IP address allocation to NAC-FE or use the IP address of user profile information in TUP-FE. After authentication, the user profile, including mobility service parameters, is delivered to TLM-FE. In the case of network-based mobility, only an IP address maintained in TUP-FE is used for IP configuration, and in the case of host-based mobility, NAC-FE delivers the allocated IP address to TLM-FE.
+
+To communicate between the user and MLM-FE (P) in the target network, TLM-FE provides the address of the MLM-FE (P) as well as the user's IP address and keying material for the security associations between the user and MLM-FE (P), as well as HDC-FE and NID-FE. The TLM-FE stores the association between the allocated IP address and related network location information, including the mobility service parameters. TLM-FE also delivers mobility service parameters to NAC-FE after notification of binding information to MLM-FE.
+
+### 7.3.2 Notification of binding information
+
+In the host-based mobility service, a mobile node directly updates location information to MLM-FE (P). NAC-FE may bind the information between the mobility service subscriber ID and the persistent/temporary IP addresses. TLM-FE then sends the binding information to the MLM-FE (P): the user identity, the type of mobility service, and keying materials. However, TLM-FE delivers the indication of network-based mobility without keying material to MLM-FE (P). In the case of network-based mobility, the user has only the persistent address and no security association with MLM-FE (P).

External reference points include S-TC1, TC-Ux, TC-T1, and TC-TC1. Internal interfaces are Nb, Nc, Nk, Na, Nd, and Ne. External interfaces to MMCF are M1, M2, and M13. The MMCF contains MLM-FE (P), MLM-FE (C), HDC-FE, NID-FE, and NIRF.
+
+**Figure 8.1 – Functional entities and reference points of NACF**
+
+## 8.1 Functional entities of NACF
+
+The following FEs of NACF are involved in the mobility service:
+
+- T-10 Network access configuration functional entity (NAC-FE)
+- T-11 Transport authentication and authorization functional entity (TAA-FE)
+- T-13 Transport location management functional entity (TLM-FE)
+
+In order to support mobility defined in [ITU-T Y.2014], NAC-FE allocates two kinds of IP addresses to UE: persistent IP address (PIA) and temporary IP address (TIA). NAC-FE allocates IP addresses in association with TAA-FE, when the address allocation is needed during the UE's movement, in order to provide authentication.
+
+TAA-FE may request NAC-FE to allocate an IP address in the case of host-based mobility, and it may use an IP address or IP prefix as user-profile information maintained in TUP-FE in both host-based and network-based mobility cases (see clause 7.2.4 of [ITU-T Y.2014]).
+
+TLM-FE identifies the current network location of UE and keeps track of it. When the point of attachment is changed in the network, the TLM-FE updates the association between the IP address allocated to the UE and related network location information (see clause 7.2.3 of [ITU-T Y.2014]).
+
+## 8.2 Relevant reference points
+
+The following external reference points between NACF and MMCF are defined for the mobility service:
+
+- M1 (TLM-FE, MLM-FE)
+- M2 (TLM-FE, HDC-FE)
+- M13 (TLM-FE, NID-FE)
+
+The following internal reference points of NACF are extensively defined for mobility service:
+
+- Nc (TAA-FE, TLM-FE)
+- Ne (NAC-FE, TLM-FE)
+
+## 8.3 Interface description
+
+This clause provides the description of the relevant reference points and interfaces listed in clause 8.2.
+
+### 8.3.1 M1
+
+This reference point is for the distribution of information from TLM-FE to MLM-FE (P). The information is prepared through the internal procedures of NACF, as follows:
+
+- 1) TLM-FE obtains persistent/temporary address from NAC-FE.
+- 2) TAA-FE delivers the profile information, including mobility-service parameters as well as the address of MLM-FE (P), to the TLM-FE.
+- 3) In the case of host-based mobility, TLM-FE obtains keying material from TAA-FE for the security associations between UE and MLM-FE (P).
+- 4) In the case of network-based mobility, TLM-FE obtains the address of MLM-FE(C) and the address of tunnel end-point from TAA-FE.
+
+TLM-FE informs MLM-FE (P) of mobile-user ID, persistent-IP address, and anchor-point address (the tunnel-end-point address) in addition to the information listed from 1 to 4. Optionally, binding information between the mobility-service-user ID and persistent-IP address, as well as the type of mobility protocol (e.g., host-based or network-based mobility service) can be included in the information.
+
+### 8.3.2 M2
+
+This reference point is for providing information from TLM-FE to HDC-FE, to support the security association required between the handover decision function (HDF) and the UE. The TLM-FE sends information including mobility-service-user ID and keying material to the HDC-FE.
+
+The M2 interface is used for information flow providing the keying material derived from the UE authentication procedure.
+
+### 8.3.3 M13
+
+This reference point is for providing information from TLM-FE to the network information distribution functional entity (NID-FE) to support the security association. The TLM-FE sends information to the NID-FE, including mobility-service-user ID and keying material.
+
+M13 interface is used for the information flow providing the keying material derived from the UE authentication procedure.
+
+### 8.3.4 Nc
+
+The Nc reference point, between TAA-FE and TLM-FE, is extended for the mobility service according to [ITU-T Y.2014] to support TLM-FE for the location registration to MMCF. The procedures described in clause 8.3.1 show the information required for the provisioning of the TLM-FE, such as the address of MLM-FE, mobility protocol type, anchor point address, and the security association between UE and MMCF. This interface is extended in the format of transport resource information indication and transport resource information response information flows, from TAA-FE to TLM-FE.
+
+### **8.3.5 Ne**
+
+The Ne reference point is extended for the mobility service according to [ITU-T Y.2014] to deliver mobility-service parameters between NAC-FE and TLM-FE. NAC-FE registers TLM-FE with the binding information between the mobility-service subscriber ID and persistent/temporary IP addresses. The TLM-FE informs the NAC-FE of the UE's PIA, mobility-protocol type, the address of MLM-FE(P), and keying material for the security associations between the UE and the MMCF. This interface is extended in the format of the mobility-service parameters indication information flow, from TLM-FE to NAC-FE.
+
+# **9 Security considerations**
+
+Security requirements within the functional requirements and architecture of NACF are addressed by the security requirements for NGN [ITU-T Y.2701]. Interfaces of NACF related to the mobility service shall follow the security requirements of NACF.
+

+
+## Mapping to IETF mobility architecture
+
+(This appendix does not form an integral part of this Recommendation.)
+
+IETF has worked on IP mobility protocols, such as MIPv4 ([b-IETF RFC 3344]), MIPv6 ([b-IETF RFC 3775]), and proxy mobile IP (PMIP) ([b-IETF RFC 5213]). Generally, mobility architecture includes two physical entities in IP networks: a home agent and an access gateway (Figure I.1). The home agent is linked to all access gateways and manages user location information and profiles. The home agent can also be located in some access gateways. In this case, the function of the home agent is distributed to access gateways; access gateways have the function of the home agent in addition to their own function. The access gateway detects user movement to a new IP network. In the network-based mobility case, an IP address of the access gateway is used as a mobile node's CoA, so that packets destined to the mobile node are delivered to the access gateway on behalf of the mobile node. Then, the access gateway directly transfers them to the mobile node that just has an IPv6 specification. Within a domain, one home agent exists and more than one home agent will be considered in the future. However, in the case of host-based mobility, a mobile node has its own HoA and CoA and receives packets directly from the home agent or a sender.
+
+NACF is responsible for IP address management and authentication to support IP mobility as some parts of access gateway functionality. MMCF can perform control parts of functions in both the home agent and access gateways, as it manages mobile node binding information.
+

+
+The diagram illustrates a network architecture for IP mobility. It features three horizontal paths at the bottom, each consisting of a 'CPE' box connected to an 'Access point' box. The first two 'Access point' boxes are connected to a single 'Access gateway' box. The third 'Access point' box is connected to its own 'Access gateway' box.

+
+## Mapping to PMIP domain
+
+(This appendix does not form an integral part of this Recommendation.)
+
+A mobile node in a proxy mobile IP (PMIP) domain is generally identified by an identifier (MN-Identifier) that has an associated policy profile. This information is typically configured in an AAA server. When a user accesses the network, the network needs to authenticate the user. NGN functions related to the access authentication in PMIP are shown in Figure II.1.
+

+
+Functional architecture for access authentication diagram
+
+**Figure II.1 – Functional architecture for access authentication**
+
+The data related to access authentication includes the subscriber identity, supported authentication methods, and authentication keys. Additionally, user data defined in the policy profile are needed in order to support PMIP [b-IETF RFC 5213]. The network entities in the PMIP domain have access to the mobile node's policy profile that contains the operational parameters required by the network entities for managing the mobile node's mobility service. Network entities, such as the mobile access gateway (MAG) and the local mobility anchor (LMA), can query this information using RADIUS [b-IETF RFC 2865] or DIAMETER [b-IETF RFC 3588] protocols.
+
+The policy profile has two mandatory fields and other optional fields, as shown in Table II.1. TUP-FE stores this information for policy profile in PMIP and may permanently store two of their mandatory parameters. Additional user data for the policy profile can be added to the transport-user profile described in [b-ITU-T Q-Sup. 58]. The network entities in a PMIP domain can identify a mobile using its MN-Identifier obtained as part of the access authentication. The MN-Identifier may be the same as the user identifier (Subscriber ID), unless it is used from more than one mobile node operating in the same PMIP domain.

+
+# Appendix III
+
+## Mapping IPv6 user configuration for the mobility service
+
+(This appendix does not form an integral part of this Recommendation.)
+
+## III.1 Initial allocation of IP address
+
+A mobile CPE in the access network domain can configure one or more IP addresses on its interface using IPv6 stateless or stateful address autoconfiguration procedures. When stateless address autoconfiguration is supported on the link, the mobile node can generate one or more IPv6 addresses by combining the network prefix advertised on the access link with an interface identifier. When stateful address autoconfiguration is supported on the link, the mobile node obtains the address configuration from the DHCPv6 server using DHCPv6 client protocol.
+
+## III.2 Interaction with DHCP relay agent
+
+If stateful address configuration using DHCP is supported on the link on which the mobile node is attached, the DHCP relay agent needs to be configured on the access router (e.g., AM-FE function in NACF). When the mobile node sends a DHCPv6 Request message, the relay agent function on the AM-FE must set the link-address field in the DHCPv6 message to the mobile node's local home network prefix, so as to provide a prefix hint to the DHCP server. Since the access link is a point-to-point link with the configured mobile node's prefix as the on-link prefix, the normal DHCP relay agent configuration on the AM-FE will ensure that the prefix hint is set to the mobile node's home network prefix.
+
+If the mobile node is IPv4 enabled, the mobile CPE after the access authentication will be able to obtain the IPv4 address configuration for the connected interface by using DHCPv4.
+
+## III.3 IPv6 address autoconfiguration
+
+Functions related to the IP address allocation are shown in Figure III.1. CPE communicates with NACF via the AR-FE in the transport functions. T-U1 and TC-T1 reference points are related to the IP address allocation. The T-U1 reference point enables the CPE to initiate requests for IP address allocation and other network configuration parameters. These requests are received by the AR-FE and are relayed to the AM-FE in NACF via the TC-T1 reference point. These reference points also provide transport IP address and network configuration information to the CPE for connecting to the network. Either DHCP or PPP is used as a method for IP address allocation and network configuration.

+
+The diagram illustrates the functional architecture for IP address allocation. It consists of three main components connected in a linear sequence: a box labeled 'CPE' on the left, a box labeled 'Transport functions' in the center, and a box labeled 'NACF' on the right. The 'CPE' is connected to the 'Transport functions' via a line labeled 'T-U1'. The 'Transport functions' are connected to the 'NACF' via a line labeled 'TC-T1'. Below the 'NACF' box, there is a small text label 'Q.3203(11)\_FIII.1'.

+
+However, IPv6 defines both stateful address configuration and stateless address autoconfiguration, which requires no manual configuration of hosts. The stateless mechanism allows a host to generate its own addresses using a combination of locally available information and information advertised by routers. Both stateless address autoconfiguration and dynamic host configuration protocol for IPv6 (DHCPv6) [b-IETF RFC 3315] may be used simultaneously.
+
+In the case of IPv6 stateless address allocation, a CPE does not use DHCP for manual configuration. Instead, CPE generates its own address using subnet prefixes advertised by routers. As NACF is not involved in the IPv6 stateless address configuration, the NAC-FE cannot maintain a mapping between the CPE and the assigned IP address and cannot forward this information to the TLM-FE, causing the TLM-FE not to respond to location queries from service control functions. In the case of autoconfiguration, an additional information flow is needed in order to register a CPE's IPv6 address to NACF via T-U1 and TC-T1 reference points. When a CPE connects to the network, it can use DHCPv6 [b-IETF RFC 3315] for IPv6 address allocation via T-U1 and TC-T1 reference points, or can configure its own address using IPv6 stateless address autoconfiguration. After an autoconfiguration process, the CPE registers its IPv6 address information to NACF.
+
+IPv6 stateless address autoconfiguration mechanism [IETF RFC 4862] defines two functions mapped to the NGN functional architecture:
+
+- The Host is a function of the CPE that autoconfigures its IPv6 address.
+- The Router is a function of transport functions in charge of advertising network information.
+
+As shown in Figure III.2, router solicitation (RS) and router advertisement (RA) are transmitted between the Host and the Router.
+
+![Figure III.2 – IPv6 autoconfiguration functional entities diagram. It shows three main components in a horizontal line: 'CPE (Host)' on the left, 'Transport functions (Router)' in the center, and 'NACF' on the right. A line labeled 'T-U1' connects 'CPE (Host)' to 'Transport functions (Router)'. Below this line, 'RS/RA' is written. Another line labeled 'TC-T1' connects 'Transport functions (Router)' to 'NACF'. In the bottom right corner of the diagram, there is a small label 'Q.3203(11)_FIII.2'.](9b9d2abd741ed4bafe7f78f89961c663_img.jpg)

+
+Registration of the binding information between a configured IPv6 address and a CPE is needed via T-U1 and TC-T1 reference points. Table III.1 describes the elements contained in the registration information flow.

+
+The IPv6 stateful address allocation process can be completed by using DHCP messages. In DHCP mode, the transport functions include an AR-FE acting as a DHCP relay between the DHCP clients in the CPE and the DHCP server in NACF (see Figure III.3). To newly support IPv6 stateless address autoconfiguration, an additional registration flow is needed between a CPE and NACF. The CPE registers address information to the NAC-FE, after the CPE configures its own IPv6 address. This information is received by AR-FE and then relayed to the AM-FE via T-U1 and TC-T1 reference points.

+
+The diagram illustrates two IPv6 address allocation flows between a CPE and a network architecture involving TF, AM-FE, NACF, and TLM-FE.
+
+**Stateful address configuration:**
+
+- The CPE sends a **1. DHCP request** to the AR-FE (within TF).
+- The AR-FE forwards this to the AM-FE.
+- The AM-FE forwards it to the NAC-FE (within NACF).
+- The NAC-FE sends a **2. DHCP response** back to the AR-FE.
+- The AR-FE then sends a **3. Inform IP address** message to the TLM-FE (within NACF).
+
+**Stateless address configuration:**
+
+- The CPE sends a **1. Router solicitation** to the AR-FE (within TF).
+- The AR-FE sends a **2. Router advertisement** back to the CPE.
+- The CPE then sends a **3. Register IPv6 address** message to the AR-FE.
+- The AR-FE forwards this to the AM-FE.
+- The AM-FE forwards it to the NAC-FE (within NACF).
+- The NAC-FE sends a **4. Inform IP address** message to the TLM-FE (within NACF).

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+
+## 5.1 Overview
+
+The network attachment control function (NACF) maintains information about IP-connectivity access sessions associated with user equipment connected to the NGN. This information is stored in the transport location management physical entity (TLM-PE) and it is pushed to or pulled from the PD-PE in the RACE when the initial attachment is established or the PD-PE needs the information to make a decision (see Figure 5-1):

+
+### 5.3.1 Transport location management physical entity (TLM-PE)
+
+The transport location management physical entity (TLM-PE) is a physical entity that implements the functionalities of the transport location management functional entity (TLM-FE) defined in the NACF. The TLM-PE registers the association between the IP address allocated to the terminal and related network location information provided by the NAC-PE, for example, access transport equipment characteristics, line identifier (logical access ID), IP edge identity, etc. The TLM-PE registers the association between network location information received from the NAC-PE and geographical location information. The TLM-PE may also store the identity of a user or a terminal to which the IP address has been allocated (information received from the TAA-PE), as well as the user network QoS profile and user preferences regarding the privacy of location information. In case the TLM-PE does not store the identity/profile of the user/terminal, the TLM-PE shall be able to retrieve this information from the TAA-PE.
+
+The TLM-PE responds to location queries from service control functions and applications. The actual information delivered by the TLM-PE may take various forms (e.g., network location, geographical coordinates, postal address, etc.), depending on agreements with the requestor and on user preferences regarding the privacy of its location. The TLM-PE interfaces with the NAC-PE to establish the association between the IP address, which is allocated by the NAC-FE to the end-user equipment, and the line ID.
+
+The TLM-PE also registers user network profile information (received from the TAA-PE at authentication) to make this profile information available to the RACE during authentication of the terminal. The TLM-PE is able to correlate the information received from NAC-PE and TAA-PE based on the logical access ID.
+
+### 5.3.2 Policy decision physical entity (PD-PE)
+
+The PD-PE is a physical entity that implements the functionalities of the policy decision functional entity (PD-FE) defined in [ITU-T Y.2111], which coordinates the resource reservation requests received from the SCE. The functionality of the PD-PE is further detailed in clause 7.2.3.2 of [ITU-T Y.2111].
+
+# 6 Signalling requirements
+
+The Ru reference point should allow information exchange as follows:
+
+- The profile information is pushed by the TLM-PE to the PD-PE.
+- The profile information is pulled by the PD-PE from the TLM-PE.
+
+The PD-PE and TLM-PE should use one of two selection mechanisms, either local static configuration or dynamic discovery, based on a globally unique IP address and/or transport subscriber ID to locate the respective communicating entities (i.e., PD-PE → TLM-PE, or TLM-PE → PD-PE).
+
+The following information flows shall be used on the Ru interface:
+
+- Transport resource information.
+- Transport resource information indication.
+- Transport resource release notification.
+
+Figure 6-1 shows the information flows between the TLM-PE and the PD-PE via the Ru interface.
+

+
+## 6.1 Transport resource information
+
+The information flow of the transport resource information request is sent by the PD-PE to the TLM-PE to request the access transport network profile information. Globally unique IP address information and/or a transport subscriber identifier should be used to discover the NACE and identify the user profile using the static configuration or dynamic discovery approaches. There are two scenarios for this pull mode: one is the failure recovery of the PD-PE, the other is the synchronization of the data in the PD-PE with the user data in the TLM-PE to avoid inconsistency. It contains the following information components (see Table 6-1).
+
+NOTE 1 – In the following tables, each information element is marked as (M) mandatory, (C) conditional or (O) optional.
+
+NOTE 2 – In this Recommendation, '(C)' implies 'Conditional mandatory'. The case of 'conditional option' is not applicable for this Recommendation.

+
+The transport resource information response information flow is sent by the TLM-PE to the PD-PE to provide the access transport network profile information during either a new resource initiation request from the SCE or the network failure recovery procedure. It contains the following information components (see Table 6-2).

+# 7 Procedure descriptions
+
+The following clauses describe the realization of the functional procedures defined in the NACF [ITU-T Y.2014] and RACF specifications [ITU-T Y.2111] using Diameter commands described in clause 9.
+
+## 7.1 General
+
+### 7.1.1 Mapping the information elements
+
+This clause describes a mapping of the information elements defined in the NACF specification onto the Diameter AVPs.
+
+In the tables that describe this mapping, each information element is marked as (M) mandatory or (O) optional:
+
+- A mandatory information element (marked as (M) in the table) shall always be present in the command. If this information element is absent, an application error occurs at the receiver and an answer message shall be sent back to the originator of the request with the Result-Code set to DIAMETER\_MISSING\_AVP. This message shall also include a Failed-AVP AVP containing the missing information element, i.e., the corresponding Diameter AVP defined by the AVP code and the other fields set as expected for this information element.
+- An optional information element (marked as (O) in the table) may be present or absent in the command, at the discretion of the application at the sending entity. Absence or presence of this information element shall not cause an application error and may be ignored by the receiver.
+
+### 7.1.2 Subscriber profile
+
+Subscriber profile information sent over the Ru interface is structured into two groups: the transport resource subscription information and the default configuration information.
+
+Tables 7-1 and 7-2 detail the involved information elements as defined in the NACF specification [ITU-T Y.2014] and their mapping to Diameter AVPs.
+
+**Table 7-1 – Default configuration information**

+
+## 7.2 Procedures on the Ru interface
+
+### 7.2.1 Transport resource information exchange
+
+#### 7.2.1.1 Overview
+
+This procedure is used by the RACF to request the transport resource information from the TLM-PE. This procedure is mapped to the commands User-Data-Request/Answer in the Diameter application specified in clause 9. Tables 7-3 and 7-4 detail the involved information elements as defined in the NACF specification [ITU-T Y.2014] and their mapping to Diameter AVPs.
+
+**Table 7-3 – Transport resource information request**
+
+| Information element name                       | Mapping to Diameter AVP | Category |
+|------------------------------------------------|-------------------------|----------|
+| Globally unique IP address                     | Globally-Unique-Address | O        |
+| Transport subscriber ID                        | User-Name               | O        |
+| NOTE – One of these elements shall be present. |                         |          |
+
+**Table 7-4 – Transport resource information response**
+
+| Information element name         | Mapping to Diameter AVP         | Category |
+|----------------------------------|---------------------------------|----------|
+| Globally unique IP address       | Globally-Unique-Address         | O        |
+| Transport subscriber identifier  | User-Name                       | O        |
+| Physical connection identifier   | Physical-Access-Id              | O        |
+| Logical connection identifier    | Logical-Access-Id               | M        |
+| Type of access transport network | Access-Network-Type             | O        |
+| Transport resource subscription  | Transport-Resource-Subscription | O        |
+
+#### **7.2.1.2 Procedure at the RACF side**
+
+The RACF may use this procedure upon reception of the resource reservation request associated with an IP-Address for which no record is stored.
+
+The RACF shall populate the transport resource information request as follows:
+
+- 1) The User-Name AVP or the Globally-Unique-Address AVP shall be included. The Globally-Unique-Address AVP shall be included in configurations where more than one IP address may be assigned per subscriber identifier.
+- 2) If present, the Globally-Unique-Address AVP shall contain a Frame-IP-Address or Frame-IPv6-Prefix AVP value, and an Address-Realm AVP. The Address-Realm AVP shall be included and set either using configuration data (in which case, all terminal equipment served by the RACF belong to the same addressing domain) or from the physical or logical interface over which was received the resource request that triggered the pull procedure.
+
+#### **7.2.1.3 Procedure at the TLM-PE side**
+
+Upon reception of the transport resource information request, the TLM-PE shall, in the following order:
+
+- 1) If the Globally-Unique-Address AVP is present, use this information as a key to retrieve the requested session information.
+- 2) If the Globally-Unique-Address AVP is absent but the User-Name AVP is present, use the latter information as a key to retrieve the requested session information.
+- 3) If both the Globally-Unique-Address AVP and the User-Name AVP are absent, return a transport resource information response with Result-Code set to DIAMETER\_MISSING\_AVF.
+- 4) If more than one record include the same subscriber identity matching the value of the User-Name AVP and no Globally-Unique-Address AVP is included, return a transport resource information response with Result-Code set to DIAMETER\_UNABLE\_TO\_COMPLY.
+
+- 5) If no session record is stored for the Globally-Unique-Address AVP or the User-Name AVP, return a transport resource information response with the Experimental-Result-Code AVP be set to DIAMETER\_ERROR\_USER\_UNKNOWN.
+
+If a unique subscriber record can be retrieved, the TLM-PE shall:
+
+- 1) Check which session data can be returned to the RACF, based on local policy rules and per-subscriber privacy information stored in the TLM-PE.
+- 2) Check whether the session data to be retrieved is currently being updated by another entity. If there is an update of the data in progress, the TLM-PE may delay the response message until the update has been completed and shall include in the response message the updated data requested. The TLM-PE shall ensure that the data returned is not corrupted by this conflict.
+
+If the TLM-PE cannot fulfil the received request for reasons not stated in the above steps, e.g., due to database error, it shall stop processing the request and set Result-Code to DIAMETER\_UNABLE\_TO\_COMPLY or an Experimental-Result-Code AVP set to DIAMETER\_USER\_DATA\_NOT\_AVAILABLE.
+
+Otherwise, the requested operation shall take place and the TLM-PE shall return the Result-Code AVP set to DIAMETER\_SUCCESS and the session data in the transport resource information response.
+
+### 7.2.2 Transport resource information indication
+
+#### 7.2.2.1 Overview
+
+This procedure is used to push session-related information from the TLM-PE to the RACF. This information flow occurs when an IP address has been allocated to a subscriber or in case a modification occurs on a profile that has already been pushed to the RACF.
+
+The TLM-PE should push session-related information to the RACF as soon as it is available to the TLM-PE. This may require the TLM-PE to pull part of the information from other components of the NACF.
+
+For the same subscriber, the TLM-PE may push several independent session records with different IP addresses, with or without the same logical access identifier.
+
+This procedure is mapped to the commands Push-Notification-Request/Answer in the Diameter application specified in clause 9. Table 7-5 details the involved information elements as defined in the NACF specification [ITU-T Y.2014] and their mapping to Diameter AVPs.
+
+**Table 7-5 – Transport resource information indication**
+
+| Information element name         | Mapping to Diameter AVP         | Category |
+|----------------------------------|---------------------------------|----------|
+| Globally unique IP address       | Globally-Unique-Address         | O        |
+| Transport subscriber identifier  | User-Name                       | O        |
+| Physical connection identifier   | Physical-Access-Id              | O        |
+| Logical connection identifier    | Logical-Access-Id               | M        |
+| Type of access transport network | Access-Network-Type             | O        |
+| Transport resource subscription  | Transport-Resource-Subscription | O        |
+| Default configuration            | Initial-Gate-Setting            | O        |
+
+#### 7.2.2.2 Procedure at the TLM-PE side
+
+The TLM-PE knows the address of the RACF entity to which the information should be pushed, either from configuration data or from the user profile (i.e., received from the TAA-PE/TUP-PE).
+
+The TLM-PE shall populate the transport resource information indication as follows:
+
+- The Globally-Unique-Address AVP shall contain a Frame-IP-Address or Frame-IPv6-Prefix AVP value, and an Address-Realm AVP.
+- The Logical-Access-Id AVP shall be present.
+
+The presence of the other AVPs depends on the user profile and local policy rules.
+
+#### 7.2.2.3 Procedure at the RACF side
+
+If the logical access ID is not included or is invalid, the RACF shall return a transport resource information indication with a Result-Code AVP value set to DIAMETER\_INVALID\_AVP\_VALUE.
+
+If the globally unique identifier contained in the Globally-Unique-Address AVP is not known, the RACF shall:
+
+- Create an internal record to store the received information for future use (i.e., for processing resource reservation requests received from the SCE).
+- Derive the following information from the logical access ID:
+  - The identification and bandwidth capacity of the layer 2 resources over which the subscriber traffic is carried.
+  - The address of the physical node(s) implementing the edge node FE and access node FE.
+- If the received information contains an Initial-Gate-Setting AVP, perform any appropriate actions to enforce the policy information. This may involve interacting with the policy enforcement physical entity (PE-PE) through the Rw interface (defined in [ITU-T Y.2111]).
+
+If the globally unique identifier contained in the Globally-Unique-Address AVP is already known, the RACF shall:
+
+- Replace the entire content of the internal record with the received information for future use.
+- If the received information contains a default configuration, perform any appropriate actions to enforce the new policy information. This may involve interacting with the PE-PE through the Rw interface.
+
+Such an update shall not have any impact on ongoing application sessions for which an authorization has already been provided by the RACF.
+
+If the contents of the request are invalid, the RACF shall return a transport resource information indication response with a Result-Code AVP value set to the appropriate value as described in clause 7.1.
+
+If the creation or modification of the session record is successful but a failure occurs during the processing of the default configuration (e.g., due to a failure in the interaction with the PE-PE), the RACF shall return a transport resource information indication response with a Result-Code AVP value set to DIAMETER\_LIMITED\_SUCCESS.
+
+If the RACF cannot fulfil the received request for reasons not stated in the above steps, e.g., due to database error, it shall stop processing the request and return a transport resource information indication response with a Result-Code AVP value set to DIAMETER\_UNABLE\_TO\_COMPLY or an Experimental-Result-Code AVP set to DIAMETER\_SYSTEM\_UNAVAILABLE. In the latter case, the TLM-PE is expected to retry after a provisioned time period.
+
+Otherwise, the requested operation shall take place and the RACF shall return the Result-Code AVP set to DIAMETER\_SUCCESS in the transport resource information indication response.
+
+### 7.2.3 Transport resource release notification
+
+#### 7.2.3.1 Overview
+
+This procedure is used by the TLM-PE to report loss of IP connectivity. This enables the RACF to remove the access profile from its internal database. This event occurs in case the allocated IP address is released (e.g., DHCP leased timer expiry) or due to a release of the underlying layer 2 resources.
+
+This procedure is mapped to the commands Push-Notification-Request/Answer in the Diameter application specified in clause 9. Tables 7-6 and 7-7 detail the involved information elements as defined in the RACF specification [ITU-T Y.2111] and their mapping to Diameter AVPs.
+
+**Table 7-6 – Transport resource release notification**
+
+| Information element name   | Mapping to Diameter AVP | Category |
+|----------------------------|-------------------------|----------|
+| Globally unique IP address | Globally-Unique-Address | M        |
+| Transport subscriber ID    | User-Name               | O        |
+
+**Table 7-7 – Transport resource release notification response**
+
+| Information element name      | Mapping to Diameter AVP         | Category |
+|-------------------------------|---------------------------------|----------|
+| Result (see Note)             | Result-Code/Experimental-Result | M        |
+| NOTE – Result of the request. |                                 |          |
+
+Result-Code AVP shall be used for errors defined in the Diameter base protocol.
+
+Experimental-Result AVP shall be used for other errors. This is a grouped AVP which contains a Vendor-Id AVP, and the error code in the Experimental-Result-Code AVP.
+
+#### 7.2.3.2 Procedure at the TLM-PE side
+
+On receipt of an external event indicating that the allocated IP address has been released or the underlying layer 2 connection has been lost, the TLM-PE shall clear all information stored against the IP address and issue a Push-Notification-Request representing a transport resource release notification.
+
+NOTE – Receipt of an indication that a layer 2 connection has been lost may lead the TLM-PE to issue several notifications, in case multiple access sessions where associated with this connection.
+
+#### 7.2.3.3 Procedure at the RACF side
+
+If the globally unique identifier contained in the Globally-Unique-Address AVP is not known, the RACF shall stop processing the request and set the Experimental-Result-Code to DIAMETER\_ERROR\_USER\_UNKNOWN in the transport resource release notification response.
+
+If the globally unique identifier contained in the Globally-Unique-Address AVP is already known, the RACF shall:
+
+- remove the existing session record;
+- interact with transfer layer entities (i.e., PE-PE) to remove transport policies associated with the session and clear associated resources;
+- notify the SCE.
+
+If the RACF cannot fulfil the received request for reasons not stated in the above steps, e.g., due to database error, it shall stop processing the request and set Result-Code to DIAMETER\_UNABLE\_TO\_COMPLY or an Experimental-Result-Code set to DIAMETER\_SYSTEM\_UNAVAILABLE. In the latter case, the TLM-PE is expected to retry after a provisioned time period.
+
+Otherwise, the requested operation shall take place and the RACF shall return an IP-Connectivity-Release-Indication response with the Result-Code AVP set to DIAMETER\_SUCCESS.
+
+# **8 Selection and the use of the protocol**
+
+The Diameter base protocol [b-IETF RFC 3588] shall be used for the Ru interface with the clarifications listed in the following clauses.
+
+## **8.1 Security**
+
+For secure transport of Diameter messages, Internet Protocol security (IPSec) may be used. Guidelines on the use of SCTP with IPSec can be found in [b-IETF RFC 3554].
+
+## **8.2 Accounting**
+
+This functionality (accounting session state machine, related command codes and AVPs) is not used on the Ru interface.
+
+## **8.3 Sessions**
+
+Diameter sessions are implicitly terminated. An implicitly terminated session is one for which the server does not maintain state information. The client does not need to send any re-authorization or session termination requests to the server.
+
+The Diameter base protocol includes the Auth-Session-State AVP as the mechanism for the implementation of implicitly terminated sessions.
+
+The client (server) shall include in its requests (responses) the Auth-Session-State AVP set to the value NO\_STATE\_MAINTAINED (1), as described in [b-IETF RFC 3588]. As a consequence, the server does not maintain any state information about this session and the client does not need to send any session termination request. Neither the Authorization-Lifetime AVP nor the Session-Timeout AVP shall be present in requests or responses.
+
+## **8.4 Transport protocol**
+
+Diameter messages over the Ru interface shall make use of SCTP specified in [b-IETF RFC 2960] and shall utilize the new SCTP checksum method specified in [b-IETF RFC 3309].
+
+## **8.5 Routing considerations**
+
+This clause specifies the use of the Diameter routing AVPs Destination-Realm and Destination-Host.
+
+Requests initiated by the TLM-PE towards the PD-PE shall include both Destination-Host and Destination-Realm AVPs. The TLM-PE obtains the Destination-Host AVP to use in requests towards a PD-PE from configuration data and/or the subscriber profile. Consequently, the Destination-Host AVP is declared as mandatory in the ABNF for all requests initiated by the TLM-PE.
+
+Requests initiated by the PD-PE towards the TLM-PE shall include both Destination-Host and Destination-Realm AVPs. The PD-PE obtains the Destination-Host AVP to use in requests towards
+
+a TLM-PE, from the configuration data. Consequently, the Destination-Host AVP is declared as mandatory in the ABNF for all requests initiated by the PD-PE.
+
+Destination-Realm AVP is declared as mandatory in the augmented Backus-Naur form (ABNF) for all requests.
+
+## 8.6 Application advertisement
+
+The TLM-PE and PD-PE shall advertise support of the Ru-specific application by including the application identifier in the Auth-Application-Id AVP within the Vendor-Specific-Application-Id grouped AVP of the Capabilities-Exchange-Request and Capabilities-Exchange-Answer commands.
+
+The vendor identifier value of ITU-T (11502) shall be included in the Supported-Vendor-Id AVP of the Capabilities-Exchange-Request and Capabilities-Exchange-Answer commands, and in the Vendor-Id AVP within the Vendor-Specific-Application-Id grouped AVP of the Capabilities-Exchange-Request and Capabilities-Exchange-Answer commands. Additionally, support of ETSI AVPs and/or 3GPP AVPs shall be advertised by adding the vendor identifier value of ETSI (13019) and/or 3GPP (10415) to the Supported-Vendor-Id AVP of the Capabilities-Exchange-Request and Capabilities-Exchange-Answer commands.
+
+NOTE – A Vendor-Id AVP included in the Capabilities-Exchange-Request and Capabilities-Exchange-Answer commands that is not included in the Vendor-Specific-Application-Id AVPs as described above indicates the manufacturer of the Diameter node as per [b-IETF RFC 3588].
+
+# 9 Ru protocol specification
+
+This clause specifies a Diameter application that allows a Diameter server and a Diameter client to exchange information related to IP-connectivity sessions. The Diameter application identifier assigned to this application is 16777262.
+
+The Diameter base protocol as specified in [b-IETF RFC 3588] is used to support information transfer on both interfaces.
+
+[b-IETF RFC 3588] shall apply except as modified by the defined support of the methods and the defined support of the commands and AVPs, result and event codes specified in this clause. Unless otherwise specified, the procedures (including error handling and unrecognized information handling) are unmodified.
+
+## 9.1 Commands
+
+This Recommendation re-uses and modifies commands defined in the Sh application [ETSI TS 129 329] for the Sh interface. Existing Diameter command codes from the Sh application are used. Only the following commands defined in the Sh application are used. Any other command defined in the Sh application shall be ignored.

+## 9.2 Result-Code AVP values
+
+This clause defines new result code values that must be supported by all Diameter implementations that conform to this Recommendation. When one of the result codes defined here is included in a response, it shall be inside an Experimental-Result AVP and Result-Code AVP shall be absent.
+
+### 9.2.1 Success
+
+Result codes that fall within the success category are used to inform a peer that a request has been successfully completed. No result codes within this category have been defined so far.
+
+### 9.2.2 Permanent failures
+
+Errors that fall within the permanent failures category are used to inform the peer that the request failed, and should not be attempted again.
+
+No errors within this category have been defined so far. However, the following error defined in the Cx and Dx application is used in this Recommendation:
+
+- DIAMETER\_ERROR\_USER\_UNKNOWN (5001).
+
+When this result code is used, the 3GPP vendor ID shall be included in the vendor-Id AVP of the Experimental-Result AVP.
+
+### 9.2.3 Transient failures
+
+Errors that fall within the transient failures category are those used to inform a peer that the request could not be satisfied at the time that it was received. The request may be able to be satisfied in the future.
+
+This Recommendation defines the following error with this category:
+
+- DIAMETER\_SYSTEM\_UNAVAILABLE (4001).
+
+This error is returned when a request could not be satisfied at the time that it was received due to a temporary internal failure or congestion. When this result code is used, the ETSI vendor ID shall be included in the Vendor-Id AVP of the Experimental-Result AVP.
+
+The following error defined in the Sh application is also used in this Recommendation:
+
+- DIAMETER\_USER\_DATA\_NOT\_AVAILABLE (4100)
+
+When this result code is used, the 3GPP vendor ID shall be included in the Vendor-Id AVP of the Experimental-Result AVP.
+
+## 9.3 AVPs
+
+The following tables summarize the AVPs used in this Recommendation beyond those defined in the Diameter base protocol.
+
+Table 9-3 describes the Diameter AVPs defined in this Recommendation, their AVP code values, types, possible flag values and whether the AVP may or not be encrypted. The Vendor-Id header of all AVPs defined in this Recommendation shall be set to ETSI (13019).
+
+NOTE – In the following tables, AVP header bit denoted as "M" indicates that support of the AVP is mandatory. AVP header bit denoted as "V" indicates that the optional Vendor-ID field is present in the AVP header.

+This clause contains the namespaces that have either been created in this Recommendation, or the values assigned to existing namespaces managed by IANA.
+
+### **9.4.1 AVP codes**
+
+This Recommendation uses AVP values from the AVP code namespace managed by ETSI for its Diameter vendor-specific applications. See clause 9.3, Tables 9-3 to 9-5.
+
+### **9.4.2 Experimental-Result-Code AVP values**
+
+This Recommendation uses the Experimental-Result-Code AVP values from the AVP Code namespace managed by ETSI for its Diameter vendor-specific applications.
+
+### **9.4.3 Command code values**
+
+This Recommendation does not assign command code values but uses existing commands defined by the IETF, including those requested by 3GPP.
+
+### **9.4.4 Application-ID value**
+
+This Recommendation defines the Ru Diameter application with application ID 16777262. The vendor identifier assigned by IANA to ITU-T (<http://www.iana.org/assignments/enterprise-numbers>) is 11502.
+
+# **10 Security considerations**
+
+The security requirements within the functional requirements and architecture of the NACF are addressed by the security requirements for NGN [ITU-T Y.2701]. The Ru interface shall follow the security requirements of the NACF.
+
+Clause 8.1 recommends the use of IPSec to ensure secure transport of Diameter messages. Guidelines on the use of SCTP with IPSec can be found in [b-IETF RFC 3554].
+
+Further security considerations are provided in the security considerations section of [b-IETF RFC 3588], which operators are advised to consult.

+## **Recommendation ITU-T Q.3230**
+
+## **Signalling requirements and protocol at the M13 interface between the transport location management and network information distribution physical entities**
+
+## **Summary**
+
+Recommendation ITU-T Q.3230 provides the protocol for the interface between the transport location management physical entity (TLM-PE) of the network attachment control entity (NACE) and the network information distribution physical entity (NID-PE) of the mobility management control entity (MMCE). The M13 interface provides the keying material, derived from the user equipment (UE) authentication procedure, in support of the security association required between the NID-PE and the UE. This Recommendation supports information flows providing the keying material via the M13 reference point as specified in Recommendation ITU-T Y.2018.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+
+## 6.1 Overview
+
+The network attachment control entity (NACE) maintains information about the keying material derived from the user equipment (UE) authentication procedure. This information is stored in the transport location management physical entity (TLM-PE) and is pushed to the network information distribution physical entity (NID-PE) in the mobility management control entity (MMCE).
+
+## 6.2 M13 reference model
+
+This clause describes the M13 reference architecture. Figure 6-1 can be used as an initial architecture illustration:

+
+## 6.3 Physical entities and capabilities
+
+### 6.3.1 TLM-PE
+
+The TLM-PE responds to location queries from service control functions and applications. The actual information delivered by the TLM-PE may take various forms (e.g., network location, geographical coordinates, postal address, etc.) depending on the agreement with the requester and on user preferences regarding the privacy of its location.
+
+The TLM-PE may play several roles, i.e., the home role, the local role, or both. In its home role the TLM-PE stores a pointer to the TLM-PE instance that is playing the local role for the attachment. The current location information of the user/CPE in the access domain is stored and bound in the local TLM-PE. Thus, when the user/CPE moves in the same access domain, only the location binding information of the local TLM-PE needs to be updated; the location binding information of the home TLM-PE does not need to be updated.
+
+The local TLM-PE is in the access network to which the terminal equipment is attached. The home TLM-PE is in the network designated by the TUP-PE. Where these networks differ, communication between the local and home TLM-PE instances takes place over the Ng reference point. Namely, the home TLM-PE may provide the SCE with user network profile information through the local TLM-PE of the visited network in order to support mobility when the user is nomadic.
+
+Similarly, the home TLM-PE is able to provide the SCE with user network profile information through the local TLM-PE of another service provider for roaming on such an access network.
+
+The functionality of the TLM-PE is further detailed in clause 7.2.3 of [ITU-T Y.2014].
+
+### 6.3.2 NID-PE
+
+The NID-PE communicates with the entity making the handover decision during the network discovery phase. The handover decision may be made by either the UE or the handover decision and control physical entity (HDC-PE). The NID-PE has the following responsibilities:
+
+- Distributing handover policy, which is a set of operator-defined rules and preferences that affect the handover decisions taken by the UE or HDC-PE.
+
+For example, a handover policy can indicate that vertical handover from E-UTRAN access to WLAN access is not allowed. It can also indicate, e.g., that WiMAX access is preferable to WLAN access.
+
+- Distributing other information provided by the NIR-PE.
+
+The functionality of the NID-PE is further detailed in clause 6.4 of [ITU-T Y.2018].
+
+# 7 Signalling requirements
+
+The M13 reference point allows the TLM-PE to interact with the NID-PE for pushing mobility service parameters such as keying material, in support of the security association required between the NID-PE and the UE.
+
+The M13 reference point is an intra-domain reference point.
+
+The M13 reference point allows information exchange as follows:
+
+- The mobility service parameters information is pushed by the TLM-PE to the NID-PE (see Figure 7-1).
+
+For further information, refer to clause 8.5.3 of [ITU-T Y.2014].

+# **8 Description of procedure**
+
+## **8.1 General**
+
+The following clauses describe the realization of the functional procedures defined in the NACE specifications using Diameter commands described in clause 10. This involves describing a mapping between the information elements defined in the NACE specification and Diameter attribute-value pairs (AVPs).
+
+In the tables that describe this mapping, each information element is marked as (M) Mandatory, (C) Conditional or (O) Optional. See [ETSI ES 283 034].
+
+## **8.2 Procedure on the M13 interface**
+
+### **8.2.1 Network selection key transfer indication**
+
+#### **8.2.1.1 Overview**
+
+This procedure is used by the TLM-PE to notify the NID-PE of the occurrence of the keying material information.
+
+This procedure is mapped to the commands Push-Notifications-Request/Answer in the Diameter application specified in the Sh interface [ETSI TS 129 329]. Tables 8-1 and 8-2 detail the involved information elements as defined in the NACE and their mapping to Diameter AVPs.

+
+#### **8.2.1.2 Procedure at the TLM-PE**
+
+The TLM-PE shall request the network selection key transfer indication request by including the following information elements:
+
+- 1) At a minimum, a Globally-Unique-Address AVP or a User-Name AVP shall be included. The Globally-Unique-Address AVP shall contain a Frame-IP-Address AVP or a Frame-IPv6-Prefix AVP, and an Address-Realm AVP.
+- 2) The Keying-Material AVP shall be present.
+
+#### **8.2.1.3 Procedure at the NID-PE**
+
+Upon reception of a network selection key transfer indication request (see Figure 8-1), the NID-PE shall:
+
+- 1) Check both the Globally-Unique-Address AVP and the User-Name AVP.
+- 2) If the Globally-Unique-Address AVP is present, go to step 6). Otherwise, go to the next step.
+- 3) If the Globally-Unique-Address AVP is absent, but the User-Name AVP is present, go to step 5). Otherwise, go to the next step.
+- 4) Because both the Globally-Unique-Address AVP and the User-Name AVP are absent, return a network selection key transfer indication response with Result-Code set to DIAMETER\_MISSING\_AV and stop this procedure. Otherwise, go to the next step.
+- 5) If more than one record include the same subscriber identity matching the value of the User-Name AVP and no Globally-Unique-Address AVP is included, return a network selection key transfer indication response with Result-Code set to DIAMETER\_UNABLE\_TO\_COMPLY and stop this procedure. Otherwise, go to the next step.
+- 6) If no session record is stored for the Globally-Unique-Address AVP or the User-Name AVP, return network selection key transfer indication response with the Experimental-Result-Code AVP set to DIAMETER\_ERROR\_USER\_UNKNOWN and stop this procedure. Otherwise, go to the next step.
+- 7) If the Keying-Material AVP is absent, return a network selection key transfer indication response with the Result-Code set to DIAMETER\_MISSING\_AV and stop this procedure. Otherwise, go to the next step.
+- 8) Under temporary overload conditions, the NID-PE shall stop processing the request and return a network selection key transfer indication response with the Experimental-Result-Code set to DIAMETER\_USER\_DATA\_NOT\_AVAILABLE and stop this procedure. Otherwise, go to the next step.
+
+- 9) If the NID-PE cannot fulfil the received request for reasons not stated in the above steps, e.g., due to database error, it shall stop processing the request and, return a network selection key transfer indication response with the Result-Code set to DIAMETER\_UNABLE\_TO\_COMPLY. Otherwise, go to the next step.
+- 10) The NID-PE shall return the Result-Code AVP set to DIAMETER\_SUCCESS in the network selection key transfer indication response and stop this procedure.

+
+# **9 Use of Diameter base protocol**
+
+With the clarifications listed in the following clauses the Diameter base protocol defined by [IETF RFC 3588] shall apply.
+
+## **9.1 Securing Diameter messages**
+
+For secure transport of Diameter messages, IP security (IPSec) may be used. Guidelines on the use of SCTP with IPSec can be found in [b-IETF RFC 3554].
+
+## **9.2 Accounting functionality**
+
+Accounting functionality (i.e., accounting session state machine, related command codes and AVPs) is not used at the M13 interface.
+
+## 9.3 Use of sessions
+
+Diameter sessions are implicitly terminated. An implicitly terminated session is one in which the server does not maintain state information. The client does not need to send any re-authorization or session termination requests to the server. See [IETF RFC 3588].
+
+The Diameter base protocol includes the Auth-Session-State AVP as the mechanism for the implementation of implicitly terminated sessions.
+
+The client (server) shall include in its requests (responses) the Auth-Session-State AVP set to the value NO\_STATE\_MAINTAINED(1), as described in [IETF RFC 3588]. As a consequence, the server does not maintain state information about this session and the client does not need to send a session termination request. Neither the Authorization-Lifetime AVP nor the Session-Timeout AVP shall be present in requests or responses.
+
+## 9.4 Transport protocol
+
+Diameter messages over the M13 interface shall make use of stream control transmission protocol (SCTP) as specified in [IETF RFC 4960] and shall utilize the new SCTP checksum method also specified in [IETF RFC 4960].
+
+## 9.5 Routing considerations
+
+This clause specifies the use of the Diameter routing AVPs; Destination-Realm and Destination-Host.
+
+With regard to the Diameter protocol used at the M13 interface, the TLM-PE acts as a Diameter server and the NID-PE acts as a Diameter client.
+
+Requests initiated by the TLM-PE towards the NID-PE shall include both Destination-Host and Destination-Realm AVPs. The TLM-PE obtains the Destination-Host AVP, to use in requests towards the NID-PE, from configuration data and/or the subscriber profile. Consequently, the Destination-Host AVP is declared as mandatory in the Augmented Backus-Naur Form (ABNF) for all requests initiated by the TLM-PE. Destination-Realm AVP is declared as mandatory in the ABNF for all requests.
+
+## 9.6 Advertising application support
+
+The Capabilities-Exchange-Request (CER) and Capabilities-Exchange-Answer (CEA) commands are specified in [IETF RFC 3588]. The Diameter base application identifier (0) shall be used in the Diameter message header of these messages.
+
+If the TLM-PE and NID-PE indicate support of the M13 application, then the M13 application identifier (16777307) shall be used in the Diameter message header of all subsequent messages exchanged within this association.
+
+Support of the M13 application within the CER/CEA is indicated by supplying an instance of the Vendor-Specific-Application-Id containing a Vendor-Id AVP set to ITU-T (11502) and an Auth-Application-Id AVP set to M13 (16777307).
+
+The TLM-PE and the NID-PE are required to advertise the support of AVPs specified in 3GPP, ETSI, and ITU-T documents by including the values 10415 (3GPP), 13019 (ETSI) and 11502 (ITU-T) in three different instances of the Supported-Vendor-Id AVP in the CER and CEA commands respectively. See Table 9-1 for vendor identifiers for M13.
+
+**Table 9-1 – Vendor identifiers for M13**
+
+| <b>Vendor</b> | <b>Vendor identifier</b> |
+|---------------|--------------------------|
+| 3GPP          | 10415                    |
+| ETSI          | 13019                    |
+| ITU-T         | 11502                    |
+
+NOTE – The Vendor-Id AVP included in CER and CEA commands that are not included in the Vendor-Specific-Application-Id AVPs as described above shall indicate the manufacturer of the Diameter node as per [IETF RFC 3588].
+
+# 10 Message specification
+
+## 10.1 Commands
+
+This Recommendation reuses the Diameter command defined in [ETSI TS 129 329]. Other commands shall be ignored by the TLM-PE and the NID-PE. See the command code in Table 10-1.
+
+**Table 10-1 – Command code**
+
+| <b>Command</b>            | <b>Abbreviation</b> | <b>Defining reference</b> | <b>Command code</b> | <b>See clause</b> |

+
+This clause contains the values assigned to the namespaces that have either been created in this Recommendation, or the values assigned to existing namespaces managed by the Internet Assigned Numbers Authority (IANA).
+
+### 10.4.1 AVP codes
+
+This Recommendation uses AVP values from the AVP Code namespace managed by ETSI for its Diameter vendor-specific applications. In addition, this Recommendation assigns AVP code values within the Diameter AVP Code namespace managed by ITU-T. See clause 10.3.
+
+### 10.4.2 Experimental-Result-Code AVP values
+
+This Recommendation assigns the Experimental-Result-Code AVP values from the AVP Code namespace managed by ETSI for its Diameter vendor-specific applications. See clause 10.2.
+
+### 10.4.3 Command code values
+
+This Recommendation does not assign command code values but uses existing commands defined by the Internet Engineering Task Force (IETF), including those requested by 3GPP.
+
+### 10.4.4 Application-ID value
+
+This Recommendation defines the M13 Diameter application with application ID 16777307. The vendor identifier assigned by IANA to ITU-T is 11502 (<http://www.iana.org/assignments/enterprise-numbers>).
+
+# 11 Security considerations
+
+The security requirements within the functional requirements and architecture of the network attachment control functions (NACF) are addressed by the security requirements for NGN [ITU-T Y.2701]. The M13 interface shall follow the security requirements of the NACF as specified in [ITU-T Y.2014].
+
+Clause 9.1 recommends the use of IPSec to ensure secure transport of Diameter messages. Guidelines on the use of SCTP with IPSec can be found in [b-IETF RFC 3554].
+
+Further considerations are provided in the security considerations section of [IETF RFC 3588].

ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary.

+# 6 Rw interface
+
+## 6.1 Overview
+
+As defined in the stage 2 specifications [ITU-T Y.2111] and [b-ITU-T Q-Sup.51], the Rw interface is used for information exchange to apply policy decisions between the PD-PE and the PE-PE that may reside in various transport devices, e.g., BGW, DSLAM/BRAS and GGSN/PDSN.
+
+The Rw interface shall be an intra-operator interface. One PD-PE instance may be able to serve more than one PE-PE instance, and one given PE-PE instance may interact with more than one PD-PE instance. For any individual session, one PD-PE instance shall make the final policy decisions in a single operator domain.
+
+The Rw interface shall be understood by the both sides of PD-PE and PE-PE which means PD-PE shall know which protocol is bound with the given PE-PE. The binding relationship can be static using dedicated well-known transport ports.
+
+In the case when PE-PE resides in various transport devices, we can use other port value (outside the well-known port range), which is a subject of a mutual agreement (= provisioning) between PE-PE and PD-PE. Alternatively, we can establish a binding relationship between PE-FE and PD-FE according to the terminal type.
+
+The Rw interface allows the PD-PE to *push* the admission decisions to the PE-PE. It also allows the PE-PE to *request* admission decisions when path-coupled resource reservation mechanisms are in use. The PD-PE may specify:
+
+- resources to be reserved and/or committed for media flows;
+- QoS handling such as packet marking and policing to use;
+- gate control (opening/closing) for a media flow;
+- insertion of a NAPT function, requesting the necessary address mapping information;
+- resource usage information request and report for a media flow;
+- dynamic firewall working mode selection for a media flow;
+- technology-independent core network ingress/egress path information for a media flow.
+
+The following provides a brief description of the information exchange requirements for the Rw interface.
+
+- *Request-response "transactions":*
+
+The interface must allow the PD-PE or the PE-PE respectively to request an action to be performed by the PE-PE or the PD-PE respectively and get a response (that can be correlated with the request) in return.
+
+NOTE 1 – Some terms like "transaction", "message", "action", "command" and others are used in a generic manner in this Recommendation. These terms may have a protocol-specific meaning, and if they do, they will be defined in the relevant Q.3303.x-specific protocol Recommendation.
+
+- *Notifications:*
+
+The interface must allow for the notification of asynchronous events (from the PE-PE to the PD-PE).
+
+– *Reliable delivery:*
+
+The interface should provide reliable delivery of messages.
+
+– *Capabilities:*
+
+The PD-PE must be able to determine capabilities when requesting resources and other transport plane functions from the PE-PE.
+
+– *Security:*
+
+All messages between the PD-PE and the PE-PE should be authenticated such that requests to the PE-PE from unauthenticated sources will not be performed and such that notifications sent from the PE-PE to the PD-PE came from an authenticated PE-PE source.
+
+– *One-to-many/many-to-one:*
+
+Two modes shall be supported:
+
+- 1) One-to-many mode, a PD-PE shall be able to communicate with multiple PE-PEs.
+- 2) Many-to-one mode, multiple PD-PEs shall be able to make requests to a given PE-PE.
+
+NOTE 2 – This mode is not supported when using COPS (ITU-T Rec. Q.3303.1).
+
+NOTE 3 – This mode requires the support of virtual MGs when using H.248 (ITU-T Rec. Q.3303.2).
+
+For either mode, only a single PD-PE shall make a request to a given PE-PE for a particular session.
+
+### 6.2 Rw reference model
+
+The Rw interface, as shown in Figure 1, is defined between the PD-PE and the PE-PE.

+## 6.3 Functional elements and capabilities
+
+#### 6.3.1 Policy decision physical entity (PD-PE)
+
+##### 6.3.1.1 Summary
+
+The PD-PE coordinates the resource requests from the SCE and/or the PE-PE, and makes policy decisions using a collection of information as described below. The PD-PE requests the resource availability information and resource admission control from the TRC-PE. Finally, the PD-PE shall request the policy enforcement operations to the PE-PE via the Rw interface. The functionality of the PD-PE is further detailed in clause 7.2.3 of [ITU-T Y.2111].
+
+The PD-PE should be able to support both push mode and pull mode according to the configuration of network operator and/or the access network type in the process of resource reservation, gate control and policy enforcement. In the push mode, the PD-PE takes the initiative in pushing down policy decisions to the PE-PE upon receipt of a request from the SCE; in the pull mode, the PD-PE should re-authorize and retrieve policy decisions upon receipt of a request from the PE-PE. The push mode is typically used in transport networks that do not support or require transport signalling for establishing network resources dynamically on behalf of, or directly by, an individual service session of the UE, e.g., DSL broadband access and Ethernet. The pull mode is typically used in transport networks that support or require the use of transport signalling to establish the network resource dynamically on behalf of or directly by an individual service session of the UE, e.g., GPRS.
+
+In addition, the PD-PE may provision the static policy configuration onto the PE-PE upon the triggers of network policies, conditions and resource status.
+
+The dynamic policy decisions are produced by the PD-PE according to the following information:
+
+- Service information received from the SCE. It consists of:
+  - Media type.
+  - Application service class.
+  - Priority.
+  - QoS information (e.g., requested bandwidth).
+- Transport subscription profile. It consists of:
+  - Maximum bandwidth per subscription (uplink/downlink).
+  - Subscribed network service class.
+  - Reservation priority.
+- Service-based network policies, non-exhaustive examples such as:
+  - Mapping rules to network service class.
+  - Maximum sessions per network service class.
+  - Time of day.
+  - Source control mode (i.e., push or pull mode).
+- Transport resource availability and admission decision information received from the TRC-PE.
+
+The *static* policy configuration may be triggered by certain conditions, e.g.,
+
+- Network policies, e.g., time of day.
+- Resource utilization.
+- Network configuration.
+- Transport subscription.
+
+##### 6.3.1.2 More details
+
+NOTE – The text in this clause is identical to that of clause 7.2.3.2 of [ITU-T Y.2111] with the following exceptions:
+
+- a) "functional entities" (FE) were replaced by "physical entities" (PE);
+- b) "reference point" was replaced by "interface".
+
+The PD-PE handles the QoS resource requests received from the SCE via the Rs interface or from PE-PE via the Rw interface. The PD-PE contains the following functions:
+
+- *Final decision point (FDP)*: This function first checks the QoS resource request based on service information, network policy rules and transport subscription information, and then
+
+interacts with the TRC-PE via the Rt interface to detect and determine the requested QoS resource within the involved access and/or core transport networks.
+
+- The FDP makes the final admission decision for media flows of a given service based on network policy rules, service information, transport subscription information and decision on resource availability.
+  - The FDP indicates the loss of connectivity: It informs the SCE that the connectivity of the transport resource previously granted is lost. The SCE may request PD-PE to relinquish all resources associated with the session.
+- *QoS mapping – Technology independent (QMTI)*: This function maps the service QoS parameters and priority received from the SCE via the Rs interface to network QoS parameters (e.g., Y.1541 class) and priority based on the network policy rules.
+  - *Gate control (GC)*: This function controls PE-PE to install and enforce the final admission decisions via the Rw interface (e.g., opening or closing the gate). The action to pass or drop IP packets is based on a set of IP gates (packet classifiers, e.g., IPv4 5-tuple) and transport interface identification information (e.g., VLAN/VPN ID) as needed.
+  - *IP packet marking control (IPMC)*: This function takes decisions on packet marking and remarking of flows. The marking may consider the priority of the flow and traffic engineering parameters.
+  - *NAPT control and NAT traversal (NAPTC)*: This function interacts with PE-PE and SCE to provide the address binding information for NAPT control and NAT traversal as needed.
+  - *Rate limiting control (RLC)*: This function makes decisions on the bandwidth limits of flows (e.g., for policing).
+  - *Firewall working mode selection (FWMS)*: This function selects the working mode of the firewall based on the service information. Four packet inspection modes could be identified (static packet filtering, dynamic packet filtering, stateful inspection, deep packet inspection, see also clause 7.2.4.1 of [ITU-T Y.2111]).
+  - *Core network path selection (CNPS)*: This function chooses the core network ingress and/or egress path for a media flow based on the service information and technology independent policy rules at the involved PD-PE.
+  - *Network selection (NS)*: This function locates core networks that are involved to offer the requested QoS resource. It locates the PE-PE instances that are involved to enforce the final admission decisions.
+
+The PD-PE shall make the final policy decisions based on the service information (e.g., service type, flow description, bandwidth and priority), transport network information (e.g., resource admission result and network policy rules) and transport subscription information (e.g., maximum upstream/downstream capacity). The policy decision shall provide sufficient information to make the PE-PE perform the resource control operation (e.g., gate opening/closing, bandwidth allocation/rate limiting, packet marking, traffic policing/shaping, NAPT and address latching). The policy decisions may be composed of flow identifier, IP addresses, bandwidth, gate status, time/volume limit, traffic descriptor, etc.
+
+The PD-PE can be stateful or stateless depending on the complexity of the specific network environment, application characteristics and deployment architecture.
+
+- The stateless PD-PE only maintains the transaction state information, e.g., state held for the duration of a request-response operation. In order to be stateless, the PD-PE shall generate the resource control session information for each resource control request from the SCF, which can be stored in the SCE, TRC-PE or PE-PE and used to retrieve the state information together with pertinent information flows.
+
+- The stateful PD-PE may maintain a variety of resource control session information within PD-PE, such as the session duration, the resource control session information (e.g., the association between SCE and PD-PE, PD-PE and TRC-PE, PD-PE and PE-PE), the resource reservation limit (e.g., time limit/volume limit), resource reservation status (i.e., authorized, reserved or committed) and physical/logical connection ID.
+
+#### 6.3.2 Policy enforcement physical entity (PE-PE)
+
+##### 6.3.2.1 Summary
+
+The PE-PE supports policy enforcement and flow-based charging. It provides the IP media flow handling and QoS control, packet filtering, marking and policing, rate limiting, flow detection and counting, NAPT and media relay, as well as online and offline charging interactions.
+
+The PE-PE should support both pull mode and push mode. In the pull mode, it shall interact with the transport signalling (e.g., PDP context in the GPRS case) to perform the resource reservation.
+
+The PE-PE should allow the IP media flow to pass through with appropriate treatment if and only if the corresponding gate is open. If the PE-PE receives an Authorization token and Flow Id(s) from a UE, the PE-PE shall report them to the PD-PE over the Rw interface. A default gate may be established for each UE during the initialization process to allow the default traffic (e.g., best effort) to pass through.
+
+The PE-PE is located at the network device (e.g., GGSN/PDSN in the GPRS/CDMA case, PDG in the WLAN case, DSLAM or BRAS in the xDSL case, CMTS in the cable network case and border gateway in general).

+NOTE – The text in this clause is identical to clause 7.2.4.1 of [ITU-T Y.2111], with the following exceptions:
+
+- "functional entities" (FE) were replaced by "physical entities" (PE);
+- "reference point" was replaced by "interface".
+
+The PE-PE enforces the network policy rules instructed by the PD-PE on a per-subscriber and per-IP flow basis. It should be able to perform the following functions based on flow information such as classifier (e.g., IPv4 5-tuple) and flow direction, as well as transport interface identification information (e.g., VLAN/VPN identifier and LSP label) as needed. The functions of the PE-PE include:
+
+- Opening and closing gate: enabling or disabling packet filtering for an IP media flow.  
+A gate is unidirectional, associated with a media flow in either the upstream or downstream direction. When a gate is open, all of the packets associated with the flow are allowed to pass through; when a gate is closed, all of the packets associated with the flow are blocked and dropped.
+- Rate limiting and bandwidth allocation.
+- Traffic classification and marking.
+- Traffic policing and shaping.
+- Mapping of IP-layer QoS information onto link layer QoS information based on predefined static policy rules (e.g., setting 802.1p priority values).
+- Network address and port translation.
+- Media relay (i.e., address latching) for NAT traversal.
+- Collecting and reporting resource usage information (e.g., start-time, end-time, packets and octets of sent and received data).
+
+- Packet-filtering-based firewall: inspecting and dropping packets based on predefined static security policy rules and gates installed by PD-PE.
+
+There are four packet inspection modes for packet-filtering-based firewall:
+
+- Static packet filtering:  
+Inspecting packet header information and dropping packets based on static security policy rules. This is the default packet inspection mode applied for all flows.
+- Dynamic packet filtering:  
+Inspecting packet header information and dropping packets based on static security policy rules and dynamic gate status.
+- Stateful inspection:  
+Inspecting packet header information as well as TCP/UDP connection state information and dropping packets based on static security policy rules and dynamic gate status.
+- Deep packet inspection:  
+Inspecting packet header information, TCP/UDP connection state information and the content of payload together, and dropping packets based on static security policy rules and dynamic gate status.

+## Recommendation ITU-T Q.3314
+
+# Requirements and protocol at the interface between the mobile location management physical entity used as a proxy and the central instance of the mobile location management physical entity (M9 interface)
+
+## Summary
+
+Recommendation ITU-T Q.3314 provides the signalling requirements and protocol for the M9 interface between the mobile location management physical entity as proxy (MLM-PE(P)) and the MLM-PE as the central instance (MLM-PE(C)) specified in Recommendation ITU-T Y.2018. The M9 interface provides information from the MLM-PE(P) and the MLM-PE(C) to registration/update and query mobility location information in both host-based and network-based mobility cases.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# Requirements and protocol at the interface between the mobile location management physical entity used as a proxy and the central instance of the mobile location management physical entity (M9 interface)
+
+# 1 Scope
+
+This Recommendation defines the protocol for the M9 interface between the mobile location management physical entity as proxy (MLM-PE(P)) and the MLM-PE as the central instance (MLM-PE(C)) specified in [ITU-T Y.2018]. The M9 reference point provides the information flows to register and update mobility location information in both host-based and network-based mobility cases specified in [ITU-T Y.2018]. In the network-based mobility case, the MLM-PE(P) sends the location registration and/or update request to the MLM-PE(C). In the host-based mobility case, the user equipment (UE) sends the location registration and/or update request to the MLM-PE(P), which will forward it to the MLM-PE(C).
+
+The M9 reference point also provides the information flows for retrieving the binding location information regarding UE's reachability. The MLM-PE(P) holds the binding information between mobile user ID (or persistent address) and temporary address (or lower tunnel end point address). The MLM-PE(C) holds the binding information between mobile user ID (or persistent address), and address of the MLM-PE(P). The MLM-PE(P) may identify the corresponding MLM-PE(C) by extracting the home domain from the mobile user ID. The MLM-PE(P) may initiate route optimization through this interface.

+# 5 M9 interface
+
+## 5.1 Overview
+
+This Recommendation specifies the protocol for the M9 reference point.
+
+The M9 reference point provides the information flows to register and update mobility location information via the M9 interface specified in [ITU-T Y.2018] in both the host-based and network-based mobility cases. The M9 reference point also provides the information flows for retrieving the binding location information regarding the UE's reachability.
+
+Therefore, two operations may occur at the M9 interface as follows:
+
+- mobility location binding registration and/or update
+- mobility location query.
+
+## 5.2 M9 reference model
+
+Figure 5-1 describes the M9 reference architecture. This illustration can be used as the initial architecture.
+
+![Figure 5-1 – M9 reference model diagram showing the architecture of the M9 interface between MMCF(P) and MMCF(C).](b28af4985cdef1e519e3aaf26561dcb3_img.jpg)
+
+The diagram illustrates the M9 reference model architecture. On the left, a 'UE' (User Equipment) is connected to an 'MMCF(P)' (Mobile Management Control Function - Provider) via the 'M3' interface. The 'UE' is also connected to a 'NACF' (Network Access Control Function) via the 'M1' interface. The 'NACF' contains a 'TLM-PE' (Transport Location Management Physical Entity). The 'NACF' is connected to an 'RACF' (Resource Admission and Control Function) via the 'M8' interface. The 'RACF' contains a 'PD-PE' (PD-PE). The 'MMCF(P)' contains a stack of physical entities: 'MLM-PE' (Mobile Location Management Physical Entity), 'HDC-PE' (HDC-PE), 'NID-PE' (NID-PE), and 'NIR-PE' (NIR-PE). These entities are connected via interfaces 'M10', 'M11', and 'M12'. The 'MLM-PE' in 'MMCF(P)' is connected to the 'MLM-PE' in 'MMCF(C)' via the 'M9' interface, which is highlighted in yellow. The 'MMCF(C)' (Mobile Management Control Function - Consumer) contains a similar stack of physical entities: 'MLM-PE', 'HDC-PE', 'NID-PE', and 'NIR-PE', connected via interfaces 'M10', 'M11', and 'M12'.

+## 5.3 Physical entities and capabilities
+
+### 5.3.1 Mobile location management physical entity (MLM-PE)
+
+The MLM-PE has the following responsibilities:
+
+- in the case of network-based mobility, initiating location registration on behalf of the UE;
+- processing location registration messages sent from, or on behalf of the UE;
+- optionally, maintaining the binding between the mobility service user ID and persistent IP address assigned to the UE;
+
+- management of the binding between the persistent IP address assigned to the UE and its temporary IP address, in the case of host-based mobility, or the address of the lower tunnel end point, in the case of network-based mobility;
+- optionally, holding two location bindings for the mobile UE by marking the binding for the serving network as active state and marking the binding for target network as standby state;
+- supporting separation of control and data plane by allowing the MLM-PE address and data forwarding end point address (i.e., tunnel end point address) to be different;
+- indication of a new mobility location binding and distribution of binding information to the HDC-PE.
+
+The MLM-PE has two roles, as proxy (MLM-PE(P)) and as the central instance (MLM-PE(C)). The MLM-PE(P) and MLM-PE(C) roles may be co-located in specific deployments providing only host-based mobility. The MLM-PE(C) provides a central point of contact for correspondent nodes (e.g., the service control function (SCF)). The MLM-PE(P) and MLM-PE(C) together provide hierarchical location management. The MLM-PE(P) holds and updates the binding between mobile user ID, persistent address, and temporary/lower tunnel end point address. The MLM-PE(C) holds the binding between mobile user ID, persistent address, and address of the MLM-PE(P). The MLM-PE(P) may identify the corresponding MLM-PE(C) by extracting the home domain from the mobile user ID.
+
+The MLM-PE(P) consists of the following functions:
+
+- In the host-based case, it provides the first point of contact for location registration for mobile users. As such, it appears as a proxy for the MLM-PE(C) from the point of view of the UE, while appearing as a proxy for the UE from the point of view of the MLM-PE(C). The mobile UE obtains the address of the MLM-PE(P) in the attachment procedure.
+- In the network-based mobility case, the MLM-PE(P) acts as a proxy for the UE from the point of view of the network side.
+- The MLM-PE(P) supports IP-based paging to locate the mobile UE.
+- In the host-based case, the MLM-PE(P) may interwork between different mobility signalling protocols (e.g., due to a difference in IP versions supported) at the UE and at the MLM-PE(C).
+- Signalling for location registration in the host-based case is secured through the security association between the UE and the MLM-PE(P). The security association is dynamically created based on the keying materials generated in the attachment procedure.
+- The MLM-PE(P) is responsible for requesting the HDC-PE to perform handover control as a consequence of mobile location registration or update.
+- The MLM-PE(P) may be the proxy of the UE for initiating route optimization, especially in the case of interworking between signalling protocols.
+- If there is a second anchor point between the UE and the anchor point to which the MLM-PE(C) corresponds, the MLM-PE(P) carries the additional address binding.
+- The MLM-PE(P) may be used to transform addresses within the signalling because of intervening network address translations (NATs).
+- The MLM-PE(P) may be used to provide address anonymity to the UE.
+
+# 6 Protocol specifications
+
+The M9 reference point enables the MLM-PE(P) to query and update binding location information from/to the MLM-PE(C). The primary parameter for retrieving the binding location information shall be the mobile user identification (ID), persistent address, and address of the MLM-PE(P).
+
+The following information primitives are used in this interface:
+
+- mobility location binding registration and/or update request and/or response;
+- mobility location query request and/or response.
+
+## 6.1 Location binding registration/update request/response
+
+This information flow is used to register and update mobility location information in both the host-based and network-based mobility cases. In the network-based mobility case, the MLM-PE(P) will send the location registration/update request to the MLM-PE(C). In the host-based mobility case, the UE will send the location registration/update request to the MLM-PE(P), which will pass it on to the MLM-PE(C).
+
+The mobility service subscriber ID and information providing the location binding between the persistent location identifier and the location of the MLM-PE(P) are included in the messages for both host-based and network-based mobility.
+
+The reference point M9 supports the following two primitives for this operation:
+
+- mobility location binding registration/update request (see Table 6-1);
+- mobility location binding registration/update response (see Table 6-2).

+
+## 6.2 Mobility location query request/response
+
+In the route optimization case (see clause 7.3.5 of [ITU-T Y.2018]), the MLM-PE(C) may query and obtain the mobile UE's current binding location information through this reference point in order to pass it to the MLM-PE(C) associated with a correspondent UE.
+
+If a related entity (e.g., a correspondent node) requests the MLM-PE(C) to provide an indication regarding UE reachability, the MLM-PE(C) may send a response to the MLM-PE(P) through this
+
+reference point to get that information. The MLM-PE(P) will send the location binding information to the related entity (e.g., correspondent node) via the MLM-PE(C).
+
+Reference point M9 supports two primitives for this purpose:
+
+- mobility location query request (see Table 6-3);
+- mobility location query response (see Table 6-4).

+## 7.1 Use of Diameter base protocol
+
+Along with the clarifications listed in the following clauses (i.e., 7.1.1-7.1.6), the Diameter base protocol defined in [b-IETF RFC 3588] shall apply.
+
+### 7.1.1 Securing Diameter messages
+
+For secure transport of Diameter messages, IPSec may be used. Guidelines on the use of stream control transport protocol (SCTP) with IPSec can be found in [b-IETF RFC 3554].
+
+### 7.1.2 Accounting functionality
+
+Accounting functionality (accounting session state machine, related command codes and AVPs) is not used at the M9 interface.
+
+### 7.1.3 Use of sessions
+
+Diameter sessions are implicitly terminated. An implicitly terminated session is one for which the server does not maintain state information. The client does not need to send any re-authorization or session termination requests to the server [b-IETF RFC 3588].
+
+The Diameter base protocol includes the Auth-Session-State AVP as the mechanism for the implementation of implicitly terminated sessions.
+
+The client (server) shall include, in its requests or responses, the Auth-Session-State AVP set to the value NO\_STATE\_MAINTAINED (1), as described in [b-IETF RFC 3588]. As a consequence, the server does not maintain any state information about this session and the client does not need to send a session termination request. Neither the Authorization-Lifetime AVP, nor the Session-Timeout AVP shall be present in requests or responses.
+
+### 7.1.4 Transport protocol
+
+Diameter messages over the M9 interface shall make use of SCTP as defined in [b-IETF RFC 2960] and shall utilize the new SCTP checksum method specified in [b-IETF RFC 3554].
+
+### 7.1.5 Routing considerations
+
+This clause specifies the use of the Diameter routing AVPs, Destination-Realm and Destination-Host.
+
+With reference to the Diameter protocol used at the M9 interface, the MLM-PE(P) acts as the Diameter client and the MLM-PE(C) acts as a Diameter server.
+
+Requests initiated by the MLM-PE(P) towards a MLM-PE(C) shall include both Destination-Host and Destination-Realm AVPs. The MLM-PE(P) obtains the Destination-Host AVP to use in requests towards a MLM-PE(C) from configuration data and/or the subscriber profile. Consequently, the Destination-Host AVP is declared as mandatory for all requests initiated by the MLM-PE. A Destination-Realm AVP is declared as mandatory for all requests initiated by the MLM-PE.
+
+### 7.1.6 Advertising application support
+
+The Capabilities-Exchange-Request (CER) and the Capabilities-Exchange-Answer (CEA) commands are specified in [b-IETF RFC 3588]. The Diameter-base application identifier (0) shall be used in the Diameter message header of these messages.
+
+If both MLM-PE(P) and MLM-PE(C) indicate support of the M9 application, then the M9 application identifier (16777306) shall be used in the Diameter message header of all subsequent messages exchanged within this association.
+
+Support of the M9 application within the CER/CEA is indicated by supplying an instance of the Vendor-Specific-Application-Id containing a Vendor-Id AVP set to ITU-T (11502) and an Auth-Application-Id AVP set to M9 (16777306).
+
+The vendor identifier value of ITU-T (11502) shall be included in the Vendor-Id AVP of the CER and CEA commands, and in the Vendor-Id AVP within the Vendor-Specific-Application-Id grouped AVP of the CER and CEA commands. Additionally, the MLM-PE(C) and the MLM-PE(P) are required to advertise the support of AVPs specified in the Diameter related documents of 3GPP, ETSI and ITU-T, by including the values 10415 (3GPP), 13019 (ETSI) and 11502 (ITU-T) in three different instances of the Supported-Vendor-Id AVP in the CER and CEA commands respectively. See Table 7-1.
+
+**Table 7-1 – Vendor identifiers for M9**
+
+| Vendor | Vendor identifier |
+|--------|-------------------|
+| 3GPP   | 10415             |
+| ETSI   | 13019             |
+| ITU-T  | 11502             |
+
+NOTE – The Vendor-Id AVP included in CER and CEA commands that are not included in the Vendor-Specific-Application-Id AVPs, as described above, shall indicate the manufacturer of the Diameter node as per [b-IETF RFC 3588].
+
+## 7.2 Diameter base protocol message mapping on the M9 interface
+
+This Recommendation uses the four Diameter commands identified in Table 7-2 which are defined in [ETSI TS 129 229] and [ETSI TS 129 272]. Other commands are ignored by the MLM-PE(P) and the MLM-PE(C).

+
+## I.1 Mobility location binding registration/update during network attachment
+
+This clause describes the information flows required to achieve mobility location binding registration/update for a mobile UE. At each stage, the procedures vary depending on UE capabilities and network arrangements. Therefore, the scenarios in this Recommendation can be referred to as examples only.
+
+The procedures for network attachment of a mobile UE differ from those for a fixed or merely nomadic terminal because:
+
+- the part of the user profile that specifies the mobility service to be granted to the UE must be made available to the access network; and
+- the functions related to mobility service must be engaged.
+
+The first task in this procedure is to obtain the user identifier for the purpose of authorizing mobility service, which will be an authentication, authorization and accounting (AAA) entity in the mobile subscriber's home network. This will, in general, lead to an authentication exchange between the UE and the AAA entity, relayed by the transport authentication and authorization physical entity (TAA-PE). After the new IP addresses are configured, the mobile UE is ready for mobility location update and new data path creation for the target network. If successful, the user traffic towards mobile UE may be forwarded to the serving network and the target network simultaneously.
+
+As noted in clause 6.4.1 in [ITU-T Y.2018], the MLM-PE(P) is the first point of contact for mobility location management signalling. The MLM-PE may hold two location bindings for the mobile UE; the binding for the serving network is marked as active while the binding for target network is marked as in standby state. To support separation of control and data plane, the MLM-PE address and the data forwarding end point address (i.e., tunnelling end point address) may be different.
+
+### I.1.1 Procedures for attachment in the case of host-based mobility
+
+Figure I.1 shows the message flow, which is divided into four phases: the mobility location registration request phase from the UE (see 1.1 in Figure I.1), the mobility location registration request phase to MLM-PE(C) (see 1.2 in Figure I.1), the mobility location registration response phase to the MLM-PE(P) (see 1.3 in Figure I.1) and the mobility binding registration response phase to the UE (see 1.4 in Figure I.1). If a hierarchical mobility mechanism is adopted and the UE moves within the scope of a single MLM-PE(P), the MLM-PE(P) will update its own mobility location bindings but does not need to notify the MLM-PE(C).

+
+Figure I.2 shows the information flows in the case of network-based mobility. The same phases apply as in the host-based case. However, because there is no potential race between a binding update from the UE and the configuration of the MLM-PE(P), the mobility location management is triggered by TLM-PE. The MLM-PE(P) initiates the mobility location management procedure at the MLM-PE(C). The mobility management functions are shown in Figure I.2. In this figure, the MLM-PE(P) pushes the mobility binding registration request to the MLM-PE(C) (see 2.2 in Figure I.2) and MLM-PE(C) replies the mobility binding registration response to the MLM-PE(P) (see 2.3 in Figure I.2).

+## I.2 Mobility location binding registration/update during handover
+
+This clause describes the information flows required to achieve handover for a mobile UE. In each stage, the procedures vary depending on UE capabilities and network arrangements. Therefore, the scenarios in this Recommendation are provided as examples only.
+
+Before the UE can achieve handover to a new access point or network, the network discovery and decision procedure must be performed. Network discovery is performed by the UE when it detects alternative access points to which it may move. The handover decision is the process of choosing an access point to which to move. Network discovery and the handover decision must consider the following three cases:
+
+- the network makes the handover decision with input from the UE;
+- the UE makes the handover decision with the assistance of information from the network;
+- the UE makes the handover decision without assistance from the network.
+
+In the latter two cases the UE can request user input or can be constrained by user intervention.
+
+### I.2.1 Procedures for location binding update in the case of host-based mobility
+
+When the UE is acting together with the network, the UE makes the handover decision process. The UE may report a list of alternative access points to the HDC-PE. The UE may indicate its preference at this time regarding which entity makes the handover decision and which entity actually triggers the handover. Based on this information, the HDC-PE requests the RACF to check network resource availability on the potential path through each candidate network, and receives the resource check result from RACF. The HDC-PE then responds to the UE with a candidate access point list that is based on the UE's input, but reflects the results of the resource check and perhaps of local policy.
+
+The UE makes its selection about the target networks, and then informs the HDC-PE (see 3.1 in Figure I.3). The HDC-PE prepares the new access point, as described in the next two clauses, and responds to the UE (see 3.2 in Figure I.3).
+
+The UE sends the mobility location binding update request to the MLM-PE(P) (see 3.3 in Figure I.3). The mobility location binding update request is then relayed to the MLM-PE(C) (see 3.4 in Figure I.3) and the MLM-PE(C) replies the mobility binding registration response to the UE via the MLM-PE(P) (see 3.5 and 3.6 in Figure I.3).
+
+After the mobility location binding update is finished, the UE is ready for new data path creation for the target network. If successful, the user traffic towards mobile UE may be forwarded to the serving network and the target network simultaneously.
+
+![Sequence diagram showing information flows for location binding update during handover in the case of host-based mobility. The diagram involves five entities: UE, HDC-PE, MLM-PE(P), TLM-PE, and MLM-PE(C). The sequence starts with the UE selecting a new link. The UE sends a '3.1 UE handover decision request' to the HDC-PE. The HDC-PE responds with '3.2 UE handover decision response'.

+
+### I.2.2 Procedures for location binding update in the case of network-based mobility
+
+The HDC-PE prepares the new access point during handover. The HDC-PE retrieves static network information about the target networks from the NID-PE and checks network resource availability on the potential path through each candidate network and receives the resource check result from RACF. Based on this information, the HDC-PE sends the network handover decision request to the UE indicating its choice of deciding entity and triggering entity. The UE reports a list of alternative
+
+access points to the HDC-PE. The UE may indicate its preference at this time regarding which entity makes the handover decision and which entity actually triggers the handover.
+
+The HDC-PE sends the mobility location binding update request to the MLM-PE(P) (see 4.3 in Figure I.4). The mobility location binding update request is then relayed to the MLM-PE(C) (see 4.4 in Figure I.4) and the MLM-PE(C) replies the mobility binding registration response to the HDC-PE via the MLM-PE(P) (see 4.5 and 4.6 in Figure I.4).
+
+After the mobility location binding update is finished, the HDC-PE is ready for mobility location update and new data path creation for the target network. The actual triggering of handover execution is done by the HDC-PE.

+
+### I.3 Route optimization considerations for network-based handover
+
+When a correspondent UE communicates with the mobile UE, normally packets from the correspondent UE will be intercepted by the transport function associated with the MLM-PE(C) (i.e., the L3HEF at the anchor point), then encapsulated and tunnelled to the current location of UE. For data path optimization, the MLM-PE(P) to which a correspondent UE is associated, may – based on administrative policies, cooperate with the MLM-PE(P) to which the mobile UE is associated to establish a direct tunnel between their respective networks. At this point the L3HEF at each end will encapsulate packets based on the location binding information exchanged between the two MLM-PE(P)s and will forward them directly to its peer L3HEF via the tunnel between them. The peer L3HEF delivers the de-capsulated packets to the correspondent or mobile UE respectively.
+
+The L3HEF is required to be aware of active communication between the mobile UE and correspondent UE. The process is triggered when it detects a flow that matches policy indicating that route optimization may be attempted. It then indicates route optimization to its associated MLM-PE(P)(A) via the HDC-PE (see 5.1 in Figure I.5). The MLM-PE(P)(A) sends a location binding query request message to the MLM-PE(C) which contains a route optimization (RO) indication (see 5.2 in Figure I.5).
+
+Upon receiving a location binding query request message including an RO request from MLM-PE(P)(A), MLM-PE(C) will perform route optimization operation and forward the location binding query request message to MLM-PE(P)(B) associated with the correspondent UE (see 5.3 in Figure I.5). MLM-PE(P)(B) replies with the location binding query response message including an RO response to MLM-PE(P)(A) via MLM-PE(C) (see 5.4 and 5.5 in Figure I.5). Upon receiving the RO response, MLM-PE(P)(A) sends the mobility location binding update request to
+
+MLM-PE(P)(B) via MLM-PE(C) (see 5.6 and 5.7 in Figure I.5). MLM-PE(P)(B) replies with a location binding update response message to MLM-PE(P)(A) via MLM-PE(C) (see 5.8 and 5.9 in Figure I.5).
+
+MLM-PE(C) may look up its location binding list and determine whether the two MLM-PE(P) instances have both registered to it. The MLM-PE(P)s are also registered to the correspondent MLM-PE(P) instance, indicating the location of each MLM-PE(P) to one another.
+
+After route optimization operations are completed between the two MLM-PE(P)s, the location binding cache in each MLM-PE(P) is updated and the optimized tunnel is installed.
+
+If the two MLM-PE(P) instances register to different MLM-PE(C) instances, the MLM-PE(C) associated with the mobile UE and MLM-PE(C) associated with the correspondent UE will coordinate with each other to provide the location of each MLM-PE(P) instance to the other. If the MLM-PE(C) associated with the mobile UE fails to retrieve the location of the MLM-PE(C) associated with the correspondent UE, it will notify the MLM-PE(P) associated with the mobile UE that route optimization is not available. The details for the different MLM-PE(C) case are shown in Figure I.6.

+![Sequence diagram illustrating route optimization considerations for the common MLM-PE(C).](58f4167687de8d7339594e5f6fbe0bc6_img.jpg)

+## **ITU-T Recommendation Q.3401**
+
+# **NGN NNI signalling profile (protocol set 1)**
+
+## **Summary**
+
+ITU-T Recommendation Q.3401 defines the IP network-to-network interface (NNI) signalling profile for use between NGN carriers of protocol set 1 for voiceband services.
+
+## **Source**
+
+ITU-T Recommendation Q.3401 was approved on 9 March 2007 by ITU-T Study Group 11 (2005-2008) under the ITU-T Recommendation A.8 procedure.
+
+## **Keywords**
+
+NGN, profile, SDP, SIP, signalling.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# NGN NNI signalling profile (protocol set 1)
+
+# 1 Scope
+
+This Recommendation contains a service-level profile, i.e., SIP/SDP interface description, between two network operators (NNI signalling profile), where the two different network operators may support different SIP/SDP profiles (i.e., they differ in terms of the SIP extensions, SIP information elements and SDP lines which are supported). Transport-level profile, e.g., RTP, is described as necessary as the media are described in the service-level signalling.
+
+NOTE 1 – Specification of the interworking between the SIP/SDP profile contained in this Recommendation and the SIP/SDP profiles in each operator's network (i.e., the functions contained inside the interworking entity/entities at the network boundary) is out of scope of this Recommendation.
+
+For the protocol set 1 of the NGN NNI signalling profile, this Recommendation covers the voiceband services such as VoIP (audio, text and so on), DTMF and T.38 fax.
+
+NOTE 2 – Support for a mobility management interface is not supported in this version of this interface. However, nomadicity of users between different networks is supported.
+
+# 2 References

+# 3 Definitions
+
+For SIP- and SDP-specific terminology, reference shall be made to [RFC 3261], [RFC 3264] and [RFC 2327]. For NGN-specific terminology, reference shall be made to [ITU-T Y.2012]. Definitions for additional terminology used in this Recommendation are as follows:
+
+**3.1 codec list:** A codec list defines the codecs that should be announced in SIP/SDP messages exchanged over the NNI based on a bilateral agreement established between the NGNs.
+
+NOTE – The purpose of the codec list is to promote interoperability, limit the number of transcodings on network connections and possibly improve network resource management.
+
+**3.2 service control functions (SCF):** The service control functions establish, monitor, support and release multimedia sessions, and manage the user's service interactions.
+
+**3.3 SIP back-to-back user agent (B2BUA):** A back-to-back user agent (B2BUA) is a concatenation of a SIP user agent client (UAC) and user agent server (UAS).
+
+NOTE – The IETF defines the B2BUA in [RFC 3261] as "a logical entity that receives a request and processes it as a user agent server (UAS). In order to determine how the request should be answered, it acts as a user agent client (UAC) and generates requests. Unlike a proxy server, it maintains dialog state and shall participate in all requests sent on the dialogs it has established. Since it is a concatenation of a UAC and UAS, no explicit definitions are needed for its behavior." (UAC and UAS behaviors are defined in [RFC 3261].) A B2BUA reformulates a message before sending it as a new request.

+
+The diagram illustrates the VoIP interconnection reference model between two providers, Provider A and Provider B. Each provider's network is represented by a yellow cloud containing three main functional blocks: 'Service control functions' (green), 'Transport functions' (yellow), and 'MG' (Media Gateway, green). The 'Service control functions' are connected to 'Transport functions', which in turn are connected to the 'MG'. The 'MG' is connected to the 'PSTN' (green cloud) via an 'SS7' link. External connections include 'IP phone' and 'Wireless' (radio tower icons) connected to the 'Service control functions'. A central vertical dashed line represents the 'Logical interfaces' between the two providers. Specifically, the 'Service control functions' of Provider A and Provider B are connected via a dashed red line (Signal (SIP)), and their 'Transport functions' are connected via a solid blue line (Bearer (RTP/IP)). A callout box with a purple border points to this dashed red line and contains the text: 'This interface is the scope of this Recommendation'. A legend at the bottom left shows a solid blue line for 'Bearer (RTP/IP)' and a dashed red line for 'Signal (SIP)'. The identifier 'Q.3401(07)\_F5-2' is located at the bottom right of the diagram.

+
+# 6 Assumptions
+
+This Recommendation is based on the following set of assumptions:
+
+- 1) It is recognized that data-oriented call control (e.g., http to a web portal on an application server), in addition to SIP-oriented call control, may occur across the NNI. For example, a network-based service may allow a user to initiate calls or control the disposition of incoming calls through a web browser interface using http. It is assumed that such data-oriented call control involves no differentiated treatment from other data traffic, and so is not described further in this Recommendation. Differentiated treatment may be desirable in some cases.
+- 2) The logical interfaces associated with the service control functions in the service stratum and the transport functions in the transport stratum enable interconnection between two service provider networks in a peering environment.
+- 3) Each provider may use a set of service control functions and transport functions to connect to multiple peer networks.
+- 4) SIP back-to-back user agent (B2BUA) functions may be used in support of network interconnection.
+- 5) Only the network-to-network interface (NNI) is supported between two peering VoIP carriers. There may be an IP transit network between two peering VoIP service providers.
+- 6) SIP is used for service-level signalling. The SIP messages may contain MIME encapsulated ISUP in order to facilitate interoperability with the PSTN. ISUP is specified in [ITU-T Q.761]-[ITU-T Q.764].
+
+- 7) RTP is used for voice transport.
+- 8) IPv4 is supported at the NNI. Support for IPv6 is optional based on bilateral agreement.
+- 9) The IPv6 operator is responsible for IPv4/IPv6 interworking.
+
+# 7 Media availability in a SIP session
+
+The following apply to any media session established across the NNI using SIP:
+
+- a) The terminating-side network of the NNI shall pass any media packets in the direction toward the originating party as soon as they are available. A primary reason is to allow the caller to hear inband call progress tones if PSTN interworking is encountered on a voice call.
+- b) The originating-side network of the NNI:
+  - shall pass media packets from the originating party in the direction toward the terminating party upon and after receiving a final SDP answer within a SIP 2xx response to the INVITE for normal dialog;
+  - may pass media packets from the originating party in the direction toward the terminating party as early as the first SDP answer has occurred, which is in a SIP 1xx response to the INVITE when early dialog has been set up. A network, as a policy, may choose not to send media packets from the originating party until the final SDP offer/answer has been made in order to avoid theft-of-service in cases where usage-sensitive billing is employed.
+- c) As per [RFC 3261], once a SIP dialog has ended, the flow of media packets shall be halted.
+- d) The absence of media packets across the NNI over any time interval in either direction shall not be taken by either network as a sufficient reason to clear the SIP session. When the status of media flows is active according to the SDP negotiation, the absence of packets across the NNI for a given duration may constitute a reason to clear the SIP session.
+
+NOTE – The absence of packets across the NNI for a given duration can be a reason to clear the SIP session only when it is sure that it is because of the failure.
+
+# 8 Codec
+
+## 8.1 Codec list
+
+It is the responsibility of entities at the rim of the NGN (e.g., NGN-TE) and network equipment originating and terminating the NGN IP media flows to negotiate and select a common codec for each "end-to-end" media session. Therefore, the NGN shall allow end-to-end negotiation within the agreed codec list between NGN entities (terminals and network elements) and may allow it outside the list based on its network policy.
+
+NOTE 1 – In case a common codec cannot be negotiated, this Recommendation does not provide procedures for the NNI.
+
+NOTE 2 – In the interest of promoting interoperability, limiting the number of transcodings on network connections and possibly improving network resource management, it is desirable that the NGNs establish bilateral agreements about the codec list. SIP/SDP messages exchanged over the NNI indicate a request to use one or more of the codecs in this codec list.
+
+The way of handling messages with codecs that are not in the codec list or with no codec in the list depends on the network policy, i.e., some networks may allow the use of codecs that are not in the codec list, while others may reject such messages.
+
+Agreement on a codec list does not put any direct requirement on the codecs that have to be implemented in the network for transcoding purposes, nor does it mean that terminals shall support
+
+all the codecs in the list. Hence, conformance of a SIP/SDP offer to the agreed list does not ensure successful codec negotiation.
+
+NOTE 3 – When the codecs to be supported across an NNI is restricted, due to network policy, a bilateral agreement, as in Note 2 is desirable. When such a bilateral agreement cannot be established, the codec list shall contain G.711 A/mu law [ITU-T G.711].
+
+NOTE 4 – While any codec may be used within the codec list based on the bilateral agreement, it is recommended that the list contain AMR NB [EN 301 703], EVRC [TIA-127-A], G.729 [ITU-T G.729], G.729A [ITU-T G.729A], G.722.1 [ITU-T G.722.1] and G.726 [ITU-T G.726]. To enable the provision of voice service with a superior quality, it is highly recommended that the list contain a wideband codec such as AMR-WB [ITU-T G.722.2], VMR-WB [TIA-1016], G.722 [ITU-T G.722], G.729.1 [ITU-T G.729.1]. To support hard of hearing, it is recommended that T.140 [ITU-T T.140] is supported as a codec in the codec list. Where the interconnect is to an existing PSTN/ISDN, it is recommended that T.140 [ITU-T T.140] is adapted to be carried over G.711 A/mu law [ITU-T G.711].
+
+NOTE 5 – For individual sessions, a call signalling element, such as a CSC-FE, an application server or an IBC-FE, that has visibility of the end-to-end codec negotiation may determine the need and may initiate transcoding between the endpoints.
+
+NOTE 6 – Although transcoding should be avoided wherever possible, the network may support transcoding to increase the chance of session establishment (e.g., in configurations where the codecs supported by the endpoints belong to the agreed list but no common codec can be found). However, agreement on a codec list does not imply that the network should support transcoding between one of the codecs in the list and any other codec, nor between any combination of the codecs in the list.
+
+## 8.2 Packetization size
+
+When a packetization size is not selected by codec negotiation between terminals and/or network elements or agreed by bilateral arrangement, a speech packetization sampling size of 10 ms should be used for G.711 coded speech; this is recommended as an optimum value balancing end-to-end delay with network utilization. It is recognized that there may be network constraints that require that a higher value is agreed by bilateral arrangement; in such cases, a value of 20 ms is recommended. It is also recognized that there should be a bilateral agreement on an upper limit of packetization size that should not be exceeded, e.g., 60 ms.
+
+NOTE – Where a packetization size is selected by codec negotiation between terminals and/or network elements, this Recommendation places no requirements on the value to be selected.
+
+# 9 Routing and addressing
+
+Table 9-1 describes URI formats that shall be supported on the NNI. Other formats may be supported.
+
+**Table 9-1 – URI formats**
+
+|         |                                                      |
+|---------|------------------------------------------------------|

+|         | Reference: [RFC 3966]                                |
+
+There can be several ways for determining the destination of the SIP message based on the tel URI; ENUM-based routing, number-based routing, and so on. In this Recommendation, it is assumed that each network knows the address information of the peer network based on the number.

+## **10.2 SIP profile**
+
+### **10.2.1 SIP profile based on RFC 3261**
+
+This clause defines a SIP profile for the SCF at the NNI interface. This clause is structured to mirror [RFC 3261] and its section numbering. The following clauses are numbered such that the fourth digit (i.e., x of 10.2.1.x) tracks the section numbers of [RFC 3261], and clause titles track the section titles of [RFC 3261].
+
+This clause defines the set of enhancements of, and restrictions on, a standard SIP implementation based on [RFC 3261].
+
+Unless otherwise stated in this Recommendation, the SCF shall act in accordance with [RFC 3261].
+
+#### **10.2.1.1 Introduction**
+
+RFC 3261 section 1 is informational.
+
+#### **10.2.1.2 Overview of SIP functionality**
+
+RFC 3261 section 2 is informational.
+
+#### **10.2.1.3 Terminology**
+
+RFC 3261 section 3 is informational.
+
+#### **10.2.1.4 Overview of operation**
+
+RFC 3261 section 4 is informational.
+
+#### **10.2.1.5 Structure of the protocol**
+
+The structure of the protocol can be found in RFC 3261 section 5, which is informational.
+
+#### **10.2.1.6 Definitions**
+
+RFC 3261 section 6 defines the terms that have special significance for SIP. Additional definitions can be found in clause 3.
+
+The reader should note that the term "client" in this clause covers both UACs and proxies.
+
+#### **10.2.1.7 SIP messages**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7 except as noted in this clause.
+
+##### **10.2.1.7.1 Requests**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.1 except as noted in this clause.
+
+The INVITE, ACK, CANCEL, BYE, UPDATE and PRACK methods shall be supported. The OPTIONS and REGISTER methods may be supported.
+
+The Request-URI shall be a SIP URI, as defined in [RFC 3261], or a tel URI, as defined in [RFC 3966]. The SIPS URI format may be supported.
+
+The Request-URI in an initial INVITE for a basic telephone call<sup>1</sup> shall identify the called party using a tel URI or by using the telephone-subscriber syntax (i.e., the dialled phone number) in a SIP URI. When the Request-URI is a SIP URI, the host part of the Request-URI shall identify the SCF or the entity to which the message is addressed.
+
+The Request-URI for other requests associated with a basic telephone call shall identify the targeted host using the IP address or FQDN, as given by the Contact header.
+
+The host part of the Request-URI typically agrees with one of the host names of the receiving server. However, if the Request-URI of a received INVITE does not so agree, the server should proxy the request to another entity based on saved translation information or pre-provisioned policy information.
+
+##### **10.2.1.7.2 Responses**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.2.
+
+##### **10.2.1.7.3 Header fields**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.3.
+
+##### **10.2.1.7.4 Bodies**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.4 except as noted in this clause.
+
+###### **10.2.1.7.4.1 Message body types**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.4.1 except as noted in this clause.
+
+The SCF shall set the SIP profile to support the message body type "application/sdp"; other message body types may be supported.
+
+---
+
+<sup>1</sup> This includes INVITEs generated as a result of forwarding.
+
+The message body type "application/sdp" shall be supported with the INVITE and UPDATE methods as well as any non-failure response to these methods. And it should be supported with the PRACK method as well as any non-failure response to the method in order to allow interworking with a H.323 network and support of services operating third party call control.
+
+The message body type "application/sdp" may be supported with failure responses, such as 488 (not acceptable here), to the above methods.
+
+###### **10.2.1.7.4.2 Message body length**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.4.2.
+
+##### **10.2.1.7.5 Framing SIP messages**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 7.5.
+
+#### **10.2.1.8 General user agent behavior**
+
+This clause and its sub-clauses apply only if the SCF acts as a UA, i.e., B2BUA or redirect server.
+
+The SCF shall behave in accordance with RFC 3261 section 8 except as noted in this clause.
+
+Support for multiple simultaneous media streams for a single call is optional.
+
+Note that the behavior defined in this clause applies only to requests and responses outside a dialog. The behavior within a dialog is defined in 10.2.1.12.
+
+##### **10.2.1.8.1 UAC behavior**
+
+The SCF shall behave in accordance with RFC 3261 section 8.1 except as noted in this clause.
+
+###### **10.2.1.8.1.1 Generating the request**
+
+The SCF shall behave in accordance with RFC 3261 section 8.1.1 except as noted in this clause.
+
+Request-URI in the request contains the address of the called party. This will normally be a telephone number, but it may also be a general SIP URI. The From and To fields in the request might contain random strings that protect the privacy of the session originator.
+
+Refer to clause 10.2.1.20 for further details of various header field values to be used.
+
+###### **10.2.1.8.1.2 Sending the request**
+
+The SCF shall behave in accordance with RFC 3261 section 8.1.2.
+
+###### **10.2.1.8.1.3 Processing responses**
+
+The SCF shall behave in accordance with RFC 3261 section 8.1.3 except as noted in this clause.
+
+Support for the SIP authorization procedures, which is used when 401 (unauthorized) or 407 (proxy authentication required) is received, is optional. If the support is provided, it shall be as specified in RFC 3261 section 8.1.3.5.
+
+Support for the SIP retry procedures, which is used when 420 (bad extension) is received, is optional. If the support is provided, it shall be as specified in RFC 3261 section 8.1.3.5.
+
+##### **10.2.1.8.2 UAS behavior**
+
+The SCF shall behave in accordance with RFC 3261 section 8.2.
+
+##### **10.2.1.8.3 Redirect servers**
+
+The SCF shall behave in accordance with RFC 3261 section 8.3 except as noted in this clause.
+
+The SCF is not required to provide the redirect server function. However, it may provide the redirect server function and invoke redirections for a limited number of INVITE requests. The
+
+rationale for limiting the number of redirections is to control SIP signalling traffic across the NNI and processing complexity associated with redirections. The Max-Forwards header (see clause 10.2.1.20), which is mandatory in all SIP requests, serves to limit the number of hops a request can make on the way to its destination. If the redirection function is supported, then the SCF shall be in accordance with RFC 3261 section 8.3.
+
+3xx response codes may be supported at the NNI, based on bilateral agreements to support redirections that may take place in the interconnecting network or in a downstream network receiving the INVITE message.
+
+#### **10.2.1.9 Cancelling a request**
+
+In this clause and in its sub-clauses, the handling that is specific to a proxy applies only if the SCF acts as a SIP proxy, the handling that is specific to a UA applies only if the SCF acts as a UA, i.e., B2BUA or redirect server, and the handling that is specific to a registrar applies only if the SCF acts as a registrar.
+
+The SCF shall behave in accordance with RFC 3261 section 9.
+
+#### **10.2.1.10 Registrations**
+
+In this clause and in its sub-clauses, the handling that is specific to a proxy applies only if the SCF acts as a SIP proxy, the handling that is specific to a UA applies only if the SCF acts as a UA, i.e., B2BUA or redirect server, and the handling that is specific to a registrar applies only if the SCF acts as a registrar.
+
+Support for the registrations is optional. If the support is provided, it shall be as specified in RFC 3261 section 10.
+
+#### **10.2.1.11 Querying for capabilities**
+
+In this clause and in its sub-clauses, the handling that is specific to a proxy applies only if the SCF acts as a SIP proxy, the handling that is specific to a UA applies only if the SCF acts as a UA, i.e., B2BUA or redirect server, and the handling that is specific to a registrar applies only if the SCF acts as a registrar.
+
+Support for querying for capabilities is optional. If the support is provided, it shall be as specified in RFC 3261 section 11.
+
+#### **10.2.1.12 Dialogs**
+
+This clause and its sub-clauses apply only if the SCF acts as a UA, i.e., B2BUA or redirect server.
+
+The SCF shall behave in accordance with RFC 3261 section 12 except as noted in this clause.
+
+##### **10.2.1.12.1 Creation of a dialog**
+
+Support for SIPS URIs is optional. If the support is provided, it shall be as specified in RFC 3261 section 12.1.
+
+##### **10.2.1.12.2 Requests within a dialog**
+
+Support for SIPS URIs is optional. If the support is provided, it shall be as specified in RFC 3261 section 12.2.
+
+##### **10.2.1.12.3 Termination of a dialog**
+
+The SCF shall behave in accordance with RFC 3261 section 12.3.
+
+#### **10.2.1.13 Initiating a session**
+
+This clause and its sub-clauses apply only if the SCF acts as a UA, i.e., B2BUA or redirect server.
+
+The SCF shall behave in accordance with RFC 3261 section 13 except as noted in this sub-clause.
+
+The UAC should include a message body type "application/sdp" with the initial INVITE whenever possible.
+
+The support of initial INVITE without SDP offer is recommended in order to allow interworking with a H.323 network and support of services operating third party call control.
+
+To support codec selection:
+
+- When the initial INVITE includes an SDP offer, an SDP answer may be included either in the provisional reliable non-failure response to the INVITE (e.g., 183 Session Progress sent reliably) or in the final non-failure response to the INVITE (i.e., 2xx), and, if not included in the provisional reliable non-failure response, shall be included in the final non-failure response.
+- When the initial INVITE does not include an SDP offer, the initial SDP offer shall be included in the first provisional reliable non-failure response to the INVITE, that is in the first 18x response sent reliably (e.g., 180 Ringing sent reliably) if any, or in the final non-failure response to the INVITE (i.e., 2xx) if not. If the initial SDP offer is included in a reliable provisional response, the SDP answer shall be included in the PRACK message acknowledging this response. If the initial SDP offer is included in the final non-failure response to the INVITE (i.e., 2xx), the SDP answer shall be included in the ACK message acknowledging this response.
+
+#### **10.2.1.14 Modifying an existing session**
+
+This clause and its sub-clauses apply only if the SCF acts as a UA, i.e., B2BUA or redirect server.
+
+The SCF shall behave in accordance with RFC 3261 section 14 except as noted in this clause.
+
+When constructing an SDP answer to a new received SDP offer contained in a re-INVITE or UPDATE method, if the SCF controls the transfer plane, listening IP address and port number negotiated during the initial SDP negotiation procedure for a given media stream should not be modified.
+
+#### **10.2.1.15 Terminating a session**
+
+This clause and its sub-clauses apply only if the SCF acts as a UA, i.e., B2BUA or redirect server.
+
+The SCF shall behave in accordance with RFC 3261 section 15.
+
+#### **10.2.1.16 Proxy bahavior**
+
+This clause and its sub-clauses apply only if the SCF acts as a SIP proxy.
+
+The SCF shall behave in accordance with RFC 3261 section 16 except as noted in this clause.
+
+Support for multiple simultaneous media streams for a single call is optional. Since parallel forking, as described in [RFC 3960], may result in multiple simultaneous media streams for a single call, the SCF should not use parallel forking. UA or outbound proxy server may restrict forking by using Request-Disposition header with 'no-fork' option tag as specified in [RFC 3841].
+
+#### **10.2.1.17 Transactions**
+
+In this clause and in its sub-clauses, the handling that is specific to a proxy applies only if the SCF acts as a SIP proxy, the handling that is specific to a UA apply only if the SCF acts as a UA, i.e., B2BUA or redirect server, and the handling that is specific to a registrar applies only if the SCF acts as a registrar.
+
+The SCF shall behave in accordance with RFC 3261 section 17 except as noted in this clause.
+
+The SCF may return an error code 486 (busy here) to an INVITE request for a user if a dialog already exists for that user and the new INVITE is not part of that dialog.
+
+#### **10.2.1.18 Transport**
+
+The SCF shall behave in accordance with RFC 3261 section 18. However, clause 12 takes precedence over RFC 3261 section 18 in case of any conflicts.
+
+#### **10.2.1.19 Common message components**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 19 except as noted in this clause.
+
+Support for the SIPS URI is optional. If the support is provided, it shall be as specified in RFC 3261 section 19.1.1.
+
+#### **10.2.1.20 Header fields**
+
+The SCF shall set the SIP profile in accordance with RFC 3261 section 20 except as noted in this clause.
+
+Below, the SIP headers defined in [RFC 3261] are listed, and the requirements for supporting them in the SCF are identified.
+
+##### **10.2.1.20.1 Accept**
+
+Support for the Accept header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.1.
+
+##### **10.2.1.20.2 Accept-Encoding**
+
+Support for the Accept-Encoding header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.2 except as noted below.
+
+The Accept-Encoding header may be used by the SCF. The "identity" encoding value shall be supported; other encodings may be supported.
+
+##### **10.2.1.20.3 Accept-Language**
+
+Support for the Accept-Language header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.3.
+
+##### **10.2.1.20.4 Alert-Info**
+
+Support for the Alert-Info header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.4.
+
+Note that there are security risks associated with acting on the Alert-Info header, as described in RFC 3261 section 20.4.
+
+##### **10.2.1.20.5 Allow**
+
+The Allow header shall be supported as specified in RFC 3261 section 20.5 except as noted below.
+
+The Allow header shall be present in the initial INVITE and the 2xx response to the initial INVITE.
+
+The header value shall list all supported methods, i.e., at a minimum, INVITE, ACK, CANCEL, BYE, UPDATE and PRACK.
+
+##### **10.2.1.20.6 Authentication-Info**
+
+Support for the Authentication-Info header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.6.
+
+##### **10.2.1.20.7 Authorization**
+
+Support for the Authorization header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.7.
+
+##### **10.2.1.20.8 Call-ID**
+
+The Call-ID header shall be supported as specified in RFC 3261 section 20.8 except as noted below. The Call-ID value shall be globally unique as described in RFC 3261 section 8.1.1.4, and it should use a suitably long random value (the value used as the 'tag' for the From header of the request might even be reused) instead of appending the IP address or hostname to the Call-ID as described in [RFC 3323] section 4.1 for protecting privacy. When privacy is requested by the session originator, the UA of the session originator should use a privacy protected Call-ID. In the case a B2BUA within the SCF is used in support of network interconnection, it may generate a privacy protected Call-ID.
+
+##### **10.2.1.20.9 Call-Info**
+
+Support for the Call-Info header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.9.
+
+Note that there are security risks associated with acting on the Call-Info header, as described in RFC 3261 section 20.9.
+
+##### **10.2.1.20.10 Contact**
+
+The Contact header shall be supported as specified in RFC 3261 section 20.10 except as noted below.
+
+The SCF shall set the SIP profile to populate the Contact header in an INVITE request, a reliable provisional response and in a 2xx response to an INVITE request, with a SIP URI. Support for any other type of URI is optional.
+
+When the user is requesting privacy, the Contact header should not contain any domain names; the IP address form should be used instead. It should be noted that, in systems with multiple network interfaces, use of the (single) IP address form can reduce the overall system reliability. If multiple interfaces exist and reliability is a concern, then refraining from use of the IP address form is considered to be a reasonable trade-off.
+
+The SCF shall set the SIP profile to populate the Contact header in a 3xx response to an INVITE request with a valid SIP URI or tel URI. If the new destination is a telephone number, it shall contain a tel URI with the number of the new destination, as described in clause 10.2.1.7.1. Support for any other type of URI is optional.
+
+##### **10.2.1.20.11 Content-Disposition**
+
+Support for the Content-Disposition header is optional. If the support is provided, it shall be as specified in RFC 3261 section 20.11 except as noted below.
+

+NOTE – Table 10-7 is described from an implementation point of view as described in Table 10-6, e.g., even if the c line in the media description is implemented, it does not mean that every media description in specific SIP/SDP message includes the c line. When the c line is included in the session description, the c line in the media description may not be included.

+
+Media themselves are out of the scope of this Recommendation, but the following are supported because they are described in SIP/SDP messages. In Table 11-1, M and O have the same meanings as defined in clause 10.1.

+# **12 Call control signalling transport**
+
+The NNI should use SIP transport over TCP unless, based on bilateral agreement, SIP transport over UDP or SCTP is used.
+
+NOTE – A service provider may have to support multiple types of SIP signalling transport depending on the peering relationships.
+
+# **13 IP protocol version**
+
+The following IP protocol versions are proposed:
+
+- 1) Support for IPv4 is mandatory.
+- 2) Support for IPv6 is optional based on bilateral agreement.
+- 3) When IPv4 and IPv6 networks interconnect, the IPv6 network shall perform addressing mapping.
+
+# **14 Security considerations**
+
+Signalling shall be secure and media may be secure based on a bilateral agreement.
+
+# Appendix I
+
+## Call/signalling flows
+
+(This appendix does not form an integral part of this Recommendation)
+
+This appendix gives example call flows for the following scenarios:
+
+- 1) PSTN—IP—(NNI)—IP—PSTN.
+- 2) PSTN—IP—(NNI)—IP—IP.
+- 3) IP—IP—NNI—IP—PSTN.
+- 4) IP—IP—(NNI)—IP—IP.
+
+The example call flows for scenarios 1, 2 and 3 are based on the flows described in [ITU-T Q.1912.5]. The interworking between ISUP and SIP is shown at the diagrammatic level to illustrate interoperability. [ITU-T Q.1912.5] provides the details of interworking between ISUP (or BICC) and SIP, including the encapsulated ISUP and SIP header precedence rules. The example call flows for scenario 4 are based on [RFC 3261].

+
+The diagram illustrates the message sequence for a successful call setup. It starts with an incoming ISUP IAM message at the left PSTN GW, which is converted to a SIP INVITE (SDP, IAM) and sent to the first IBC-FE. This is followed by a 100 Trying response. The INVITE is then forwarded through an IP NNI to the second IBC-FE, which generates its own 100 Trying (Note). The INVITE is then sent to the right PSTN GW, which generates an ACM and a 180 Ringing (SDP, ACM) response. The 180 Ringing is forwarded back through the IBC-FEs, and a 200 OK (INVITE) (SDP, ANM) is generated by the right IBC-FE. The 200 OK is forwarded back through the IBC-FEs, and an ACK is generated by the left IBC-FE. The final ACK is sent to the right PSTN GW, which generates an ANM message. The RTP bearer path is shown as a large green arrow at the bottom, spanning from the left PSTN GW to the right PSTN GW.

+
+The diagram illustrates the sequence of messages for a normal call release without tone provision. It shows the interaction between two PSTN Gateways (GW) and several Front-End (FE) units. The PSTN GW on the left contains BGC-FE, MGC-FE, TMG-FE, and SG-FE. The PSTN GW on the right contains BGC-FE, MGC-FE, SG-FE, and TMG-FE. Between them are IBC-FE and IBG-FE units connected via an IP NNI. The sequence starts with a REL message from the left PSTN GW, which is mapped to a RLC message. This is followed by a BYE (REL) message from the left PSTN GW to the first IBC-FE. The IBC-FE then forwards the BYE (REL) message to the next IBC-FE. The second IBC-FE forwards it to the third IBC-FE. The third IBC-FE then sends a 200 OK (BYE) (RLC) message back to the second IBC-FE. The second IBC-FE forwards this back to the first IBC-FE. The first IBC-FE then sends a 200 OK (BYE) (RLC) message back to the left PSTN GW. Finally, the left PSTN GW sends a RLC message back to the external entity, completing the release. The right PSTN GW also sends a REL message, which is mapped to a RLC message, and receives a 200 OK (BYE) (RLC) message from the third IBC-FE.

+
+The diagram illustrates the sequence of messages for a normal call release initiated from the ISUP side. It features three main entities: a PSTN GW (containing BGC-FE, MGC-FE, TMG-FE, and SG-FE), a series of intermediate nodes (IBG-FE, IBC-FE, IP NNI, IBC-FE, IBG-FE), and a SIP UA. The process begins with a REL message from the PSTN GW, followed by a RLC message (indicated by a circle with an X). The PSTN GW then sends a BYE message to the first IBC-FE. This message is forwarded through the IP NNI to the next IBC-FE, then to the IBG-FE, and finally to the SIP UA. The SIP UA responds with a 200 OK (BYE) message, which is then forwarded back through the IBG-FE, IBC-FE, IP NNI, IBC-FE, and IBG-FE, and finally back to the PSTN GW, which sends a 200 OK (BYE) message back to the initiator.

+The diagram illustrates the message sequence for a normal call release at the SIP NNI. It features two entities, each enclosed in a dashed box. The left entity contains an IBG-FE and an IBC-FE. The right entity also contains an IBG-FE and an IBC-FE. The IBC-FEs are connected via an IP NNI. The sequence of messages is as follows: a BYE message is sent from the left IBC-FE to the right IBC-FE, and a 200 OK (BYE) message is sent from the right IBC-FE back to the left IBC-FE. The diagram is labeled Q.3401(07)\_FA-8.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+
+## 6.1 Dual stack + NAT mode with IPoE access
+
+Figure 6-1 depicts the dual stack + network address translation (NAT) mode with Internet Protocol over Ethernet (IPoE) access to support end-to-end broadband services. Depending on the working mode of customer premise equipment (CPE), i.e., either route mode or bridge mode, the transition is divided into two further sub-modes.
+
+![Diagram of Dual stack + NAT mode with IPoE access showing network architecture and traffic flows for route and bridge modes.](07b17a620c75522d53916a11e12d1bff_img.jpg)
+
+The diagram illustrates the network architecture for Dual stack + NAT mode with IPoE access. It is divided into five vertical zones: Terminal, Access, Metro, Core, and Servers.
+
+- Terminal:** Contains icons for TV, PC, and Phone connected to a CPE device.
+- Access:** Contains an "Access node" icon.
+- Metro:** Contains two "Edge node" icons within a cloud, labeled "IPv4/IPv6 dual stack".
+- Core:** Contains two "Core node" icons within a cloud.
+- Servers:** Contains two globe icons labeled "IPv4" and "IPv6".
+
+Below the zones, the diagram shows two traffic flow scenarios:
+
+- CPE route mode:**
+  - The NAT44 function is located at the CPE.
+  - IPv4 traffic from the CPE goes through NAT44 to a "Public IPv4" path.
+  - IPv6 traffic from the CPE goes through a "DS+NAT44+IPoE" path.
+- CPE bridge mode:**
+  - The NAT44 function is located at the Edge node in the Metro zone.
+  - IPv4 traffic from the CPE goes through the Edge node's NAT44 to a "Public IPv4" path.
+  - IPv6 traffic from the CPE goes through a "DS+NAT44+IPoE" path.

+Figure 6-1 – Dual stack +NAT mode with IPoE access to support broadband services
+
+When the CPE works in route mode, user Internet Protocol version 4 (IPv4) traffic passes through two devices which perform NAT functions. The first NAT function is executed in the CPE to perform translation from the IPv4 address of the user private network to an IPv4 address of the carrier private network (see [IETF RFC 6598]). The second NAT function is executed in the carrier network to perform translation from the IPv4 address of the carrier private network to an IPv4 address in the public network.
+
+When the CPE works in bridge mode, user IPv4 traffic passes through only one device performing a NAT function. This NAT function is executed in the carrier network to perform translation from the IPv4 address of the user private network to an IPv4 address in the public network.
+
+For both sub-modes, the procedures for IPv6 traffic end-to-end transmission are described in clause 7.1.
+
+## 6.2 Dual stack + NAT mode with PPPoE access
+
+Figure 6-2 depicts the dual stack + NAT mode with point-to-point protocol over Ethernet (PPPoE) access to support end-to-end broadband services; both IPv4 and IPv6 access are required to support a PPPoE session. Depending on the working mode of the CPE, i.e., either route mode or bridge mode, the transition is divided into two further sub-modes.

+![Figure 6-2: Dual stack + NAT mode with PPPoE access to support broadband services. The diagram shows network architecture and traffic paths for IPv4 and IPv6.](367926125450c2bc3f4bdca9d59a62ba_img.jpg)
+
+The diagram illustrates the network architecture and traffic paths for IPv4 and IPv6 in dual stack + NAT mode with PPPoE access. It is divided into three horizontal sections: Network Architecture, Traffic Path (CPE route mode), and Traffic Path (CPE bridge mode).
+
+- Network Architecture:**
+  - Terminal:** Contains icons for TV, PC, and Phone connected to a CPE.
+  - Access:** Contains an icon for an Access node.
+  - Metro:** Contains two Edge nodes, each labeled "IPv4/IPv6 dual stack".
+  - Core:** Contains two Core nodes.
+  - Servers:** Contains icons for IPv4 and IPv6 servers.
+- Traffic Path (CPE route mode):**
+  - Shows two horizontal pipes representing traffic paths.
+  - The top pipe (IPv4) starts at the CPE, passes through a NAT44 function, then a PPPoE tunnel, then another NAT44 function in the Metro, and finally becomes "Public IPv4" in the Core.
+  - The bottom pipe (IPv6) starts at the CPE and passes through the Metro and Core without NAT functions, labeled as "DS+NAT44+PPPoE".
+- Traffic Path (CPE bridge mode):**
+  - Shows two horizontal pipes representing traffic paths.
+  - The top pipe (IPv4) starts at the CPE, passes through a PPPoE tunnel, then a NAT44 function in the Metro, and finally becomes "Public IPv4" in the Core.
+  - The bottom pipe (IPv6) starts at the CPE and passes through the Metro and Core without NAT functions, labeled as "DS+NAT44+PPPoE".

+**Figure 6-2 – Dual stack +NAT mode with PPPoE access to support broadband services**
+
+When the CPE works in route mode, a PPPoE session, which is required to support IPv4 and IPv6 protocols, is initiated in the CPE and terminated in a carrier edge device, such as a broadband remote access server (BRAS). User IPv4 traffic passes through two devices performing NAT functions. The first NAT function is executed in the CPE to perform translation from the IPv4 address of the user private network to an IPv4 address of the carrier private network (see [IETF RFC 6598]). The second NAT function is executed in the carrier network to perform translation from the IPv4 address of the carrier private network to an IPv4 address in the public network.
+
+When the CPE works in bridge mode, a PPPoE session, which is required to support IPv4 and IPv6 protocols, is initiated in the user's terminal and terminated in a carrier edge device, such as a BRAS. User IPv4 traffic passes through only one device performing a NAT function. User traffic is initiated in user equipment and terminated in a carrier edge device, such as BRAS. The NAT function is
+
+executed on the carrier network side to perform translation from the IPv4 address of the user private network to an IPv4 address in the public network.
+
+For both sub-modes, IPv6 traffic is encapsulated into a PPPoE session in the CPE or in the user's terminal, and is decapsulated in a carrier edge device (e.g., BRAS). The procedures for IPv6 traffic end-to-end transmission are described in clause 7.2.
+
+## 6.3 DS-Lite with PPPoE access
+
+Figure 6-3 depicts dual stack-lite (DS-Lite) [IETF RFC 6333] mode with PPPoE access to support end-to-end broadband services. In this mode, the CPE is generally required to be configured to work in route mode.
+
+![Figure 6-3: DS-Lite with PPPoE access to support broadband services. The diagram shows a network architecture with five main components: Terminal, Access, Metro, Core, and Servers. The Terminal section includes a TV, PC, and Phone connected to a CPE. The Access section contains an Access node. The Metro section includes two BNGs (IPv6 only) and two Edge nodes (IPv4/IPv6 dual stack). The Core section contains two Core nodes. The Servers section includes IPv4 and IPv6 servers. Below the network diagram, a traffic flow diagram shows two modes: 'CPE route mode' where Private IPv4 traffic is encapsulated in a 4in6 tunnel over a Public IPv4 path, and 'DS-Lite+NAT44+PPPoE' where IPv6 traffic is encapsulated in a PPPoE session. A NAT44 device is shown between the 4in6 tunnel and the Public IPv4 path.](daa4a6fa7e2ba1954258f86b4928eb32_img.jpg)

+
+A DS-Lite tunnel established between the CPE and a carrier edge device (e.g., BRAS), and a PPPoE session supporting IPv6 is required. The user IPv4 traffic initiated from the CPE is encapsulated into a DS-Lite tunnel, and then transmitted to the carrier edge device in a PPPoE session. The carrier edge device (e.g., BRAS) terminates the PPPoE session and decapsulates the IPv4 traffic from the DS-Lite tunnel, and then performs translation from the IPv4 address of the user private network to an IPv4 address in the public network. User IPv6 traffic is also encapsulated into a PPPoE session in the CPE and decapsulated in the carrier edge device (e.g., BRAS).

+# 7 Protocol procedures
+
+## 7.1 Procedures for dual stack + NAT with IPoE access
+
+In the mode "dual stack + NAT with IPoE access", user IPv4 packets require one or two NAT operations to be performed when transmitted, but user IPv6 packet do not require any NAT operations. In this mode, the CPE and/or the edge node must maintain a NAT44 mapping table and implement the IP address mapping from private IPv4 addresses to public IPv4 addresses.

+**Figure 7-1 – Procedure for dual stack + NAT with IPoE access with CPE working in route mode**
+
+Figure 7-1 depicts the procedure for user IPv4 packet transmission with the CPE working in route mode with the mode of "dual stack + NAT with IPoE access". In this mode, the CPE obtains IPv4 address and domain name server (DNS)-related information from the carrier edge device through the dynamic host configuration protocol (DHCP). The user then also obtains their IPv4 address and DNS-related information from the CPE through DHCP. When user traffic is transmitted end-to-end, it needs to go through two levels of NAT mapping. The first level of NAT mapping is executed in the CPE device and maps from the user private IPv4 address to the carrier private IPv4 address; the second level of NAT mapping is executed in the carrier edge device (e.g., BRAS) and maps from the carrier private IPv4 address to the public IPv4 address. In this case, both the CPE and the carrier edge device must maintain a NAT mapping table.
+
+![Sequence diagram illustrating the procedure for dual stack + NAT with IPoE access with CPE working in bridge mode. The diagram shows the interaction between a Terminal, CPE, Edge node, Core node, and Server. The process starts with a DHCP request from the Terminal to the Edge node, followed by a DHCP response from the Edge node to the Terminal. The CPE then creates a NAT44 table entry. Subsequent IPv4 packets are transmitted from the Terminal to the Edge node, then to the Core node, then to the Server, and back through the Core node and Edge node to the Terminal. The CPE performs NAT mapping at the Edge node.](d4af765160d04ecef538e5066006dc77_img.jpg)

+
+**Figure 7-2 – Procedure for dual stack + NAT with IPoE access with CPE working in bridge mode**
+
+Figure 7-2 depicts the procedure for user IPv4 packet transmission with the CPE working in bridge mode with the mode of "dual stack + NAT with IPoE access". In this mode, the difference from the procedure described in Figure 7-1 is that the user IPv4 packet end-to-end transmission only needs to go through one level of NAT mapping. The NAT mapping is executed at the carrier edge device (e.g., BRAS), from the user private IPv4 address to the public IPv4 address. Only the carrier edge device needs to maintain a NAT mapping table.
+
+In the mode "dual stack + NAT with IPoE access", terminals can transmit IPv6 traffic directly without NAT. According to different CPE working modes and IPv6 address configuration methods, there are several IPv6 traffic transmission procedure options; for any one of these options, the basic procedure is similar. In this Recommendation, a CPE working in route mode is chosen as a typical mode to explain the IPv6 traffic transmission procedure. Referring to Figure 7-3 and Figure 7-4, two different IPv6 address configuration methods in the terminal are described. The first method uses neighbour discovery protocol (NDP) [IETF RFC 4861] while the second method uses dynamic host configuration protocol version 6 (DHCPv6) [IETF RFC 3315].
+
+An IPv6 address consists of an IPv6 prefix and interface identifier (ID) [IETF RFC 4291]. The IPv6 prefix assigned for a terminal should be allocated by the carrier using dynamic host configuration protocol version 6 - prefix delegation (DHCPv6-PD) [IETF RFC 3633]. The terminal can then obtain its IPv6 prefix by the Router Advertisement message in NDP or by DHCPv6. An interface ID can be calculated based on the interface's media access control (MAC) value [IETF RFC 4291].

+
+Figure 7-3 depicts the mode of IPv4/IPv6 dual stack with the CPE working in route mode, and with the CPE obtaining its wide area network (WAN) IPv6 prefix from the network using NDP. At the same time, the CPE requests an IPv6 prefix delegation from the carrier edge device (e.g., BRAS) using DHCPv6. After obtaining an IPv6 prefix for the user network, a CPE can announce this IPv6 prefix to the terminal using NDP. When obtaining an IPv6 prefix, the CPE and terminal automatically generate an IPv6 address with an interface ID. The CPE and terminal can obtain DNS-related information using DHCPv6. User data are all encapsulated into IPv6 packets for transmission.

+Sequence diagram showing the procedure for dual stack + NAT with PPPoE access with CPE working in route mode. The diagram illustrates the interaction between Terminal, CPE, Edge node, Core node, and Server. It details the steps for PPPoE discovery, DHCP request/response, and IPv4 packet translation at both the CPE and Edge node using NAT44 tables.
+
+**Figure 7-5 – Procedure for dual stack + NAT with PPPoE access with CPE working in route mode**
+
+In route mode, as shown in Figure 7-5, the CPE obtains a carrier private IPv4 address and DNS-related information from a carrier edge node using the PPPoE protocol. The terminal obtains a private IPv4 address and DNS-related information from the CPE using DHCP. When sending user data, the CPE executes the first level of NAT mapping from a user private IPv4 address to a carrier private IPv4 address. Then, the carrier edge node executes the second level of NAT mapping from a carrier private IPv4 address to a public IPv4 address. When receiving user data, the carrier edge node executes the first level of NAT mapping from the public IPv4 address to the carrier private IPv4 address. The CPE then executes the second level of NAT mapping from the carrier private IPv4 address to the user private IPv4 address. Both the CPE and carrier edge node must maintain NAT mapping tables.
+
+Figure 7-6 depicts the IPv4 traffic transmission procedure with CPE working in bridge mode. IPv4 data sent along the transmission path will be processed by one NAT device, the carrier edge node (e.g., BRAS), which translates a user private network IP address to a public network IP address.
+
+![Sequence diagram showing the procedure for dual stack + NAT with PPPoE access with CPE working in bridge mode. The diagram involves five lifelines: Terminal, CPE, Edge node, Core node, and Server. The process starts with PPPoE discovery and session establishment between Terminal and Edge node. Then, a DHCP request and response are exchanged between Terminal and Edge node. Next, the CPE creates a NAT44 table entry. The Terminal sends an IPv4 packet to the CPE, which is then forwarded by the Edge node to the Core node, then to the Server. The Server responds with an IPv4 packet that is routed back through the Core node and Edge node to the CPE, which then forwards it to the Terminal. NAT mapping is performed at the Edge node for outgoing traffic and at the CPE for incoming traffic.](fa859e4e468bfb2710a94527f2c504af_img.jpg)

+
+In bridge mode, as shown in Figure 7-6, the terminal obtains a user private network IPv4 address and DNS-related information from a carrier edge node using the PPPoE protocol or DHCP. When a terminal is transmitting user data, the carrier edge node executes the NAT mapping from a user private network IPv4 address to a public network IPv4 address. When the terminal is receiving data, the carrier edge node executes the NAT mapping from the public network IPv4 address to the user private network IPv4 address. The carrier edge node must maintain the NAT mapping table.

+## 7.3 Procedures for DS-Lite with PPPoE access
+
+Figure 7-9 depicts the IPv4 traffic transmission procedure in DS-Lite + PPPoE mode. IPv4 data sent along the transmission path are orderly encapsulated in a DS-Lite tunnel (IPv4 in IPv6 tunnel) [IETF RFC 6333] and the PPPoE session at the CPE, and then decapsulated in the PPPoE session and DS-Lite tunnel. The user data IPv4 address is translated from a user private network IPv4 address to a public network IPv4 address at the carrier edge node (e.g., BRAS).

The process starts with PPPoE discovery and session establishment between CPE and Edge node. Then, a DS-Lite tunnel is established. The Terminal sends a DHCPv4 message exchange to the CPE for IP address and DNS assignment. When the Terminal sends an IPv4 packet, the CPE creates a NAT44 table entry (Terminal private network IP <-> Public network IP), encapsulates the packet as (IPv4 in IPv6) over PPPoE, and sends it to the Edge node. The Edge node decapsulates it to an IPv4 packet, which is routed through the Core node to the Server. The Server's response is routed back through the Core node to the Edge node. The Edge node looks up the NAT44 table, encapsulates the packet as (IPv4 in IPv6) over PPPoE, and sends it back to the CPE. Finally, the CPE decapsulates the packet and sends the IPv4 packet to the Terminal.](9c6461e1e94afae4dec455e69a2ce152_img.jpg)

+
+As shown in Figure 7-9, the CPE obtains IPv6 prefix and DNS-related information from a carrier edge node using PPPoE and then sets up a DS-Lite tunnel with the carrier edge node. The terminal obtains private IPv4 address and DNS-related information from the CPE using DHCP. When a terminal is sending user data, the CPE encapsulates these data into a DS-Lite tunnel. The carrier edge node decapsulates the packets, and translates a user private IPv4 address into a public IPv4 address which creates a NAT mapping item. When a terminal is receiving data, the carrier edge node translates a public IPv4 address into a user private network IPv4 address according to the NAT mapping table, and encapsulates the packet into a DS-Lite tunnel. A CPE decapsulates the packet by removing the IPv6 header and sends it to a terminal.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+## Recommendation ITU-T Q.3645
+
+## Protocol at the interface between two distributed ENUM servers for IMS
+
+# 1 Scope
+
+This Recommendation specifies the protocol at the interface between two distributed ENUM servers (DES) of distributed ENUM networking in support of IP Multimedia core network subsystem (IMS) interconnection. The functions and signalling requirements for this interface are contained in [ITU-T Q.3643].
+
+Using the protocol specified in this Recommendation, the DES can:

+# 6 Interface between two distributed ENUM servers
+
+## 6.1 Overview
+
+The Idd interface (defined in clause 6.2) is used for information exchange to synchronize the status and the ENUM data profile of the distributed ENUM servers. The information is used by the IMS SIP proxy for ENUM resolution.
+
+The Idd interface is an inter-operator interface. One distributed ENUM server shall be able to interact with a number of distributed ENUM servers via Idd interfaces in support of interconnection with ENUM servers in different IMS domains.
+
+## 6.2 Idd reference model
+
+The Idd interface, as shown in Figure 6-1, is defined between two distributed ENUM servers for IMS inter-domain connection. The Idd interface is used for node management and ENUM data management in the distributed ENUM networking environment.
+

The diagram is split into two halves, Operator a and Operator b, separated by a central Idd interface. On Operator a's side, an IMS node connects to an ENUM (Operator level) node, which connects to a Distributed ENUM server (DES). On Operator b's side, a Distributed ENUM server (DES) connects to an ENUM (Operator level) node, which connects to an IMS node. The Idd interface is shown as a horizontal line with a break in the middle, connecting the two DES nodes.](740442c999390734911677f01af0316d_img.jpg)

+## 6.3 Functional elements and capabilities
+
+The DES is a functional element that serves for inter-operator IMS session establishment and provides mapping of ITU-T E.164 numbers to uniform resource identifiers (URIs). The DES stores the ENUM mapping data profile of the host operator and the connecting operators. It performs the ENUM data management procedures to synchronize the ENUM data profile of the connecting DES via Idd interface.

+
+## 7.3 Error handling procedures
+
+### 7.3.1 Message acknowledgement and response timeout
+
+When a DES sends a request/response message which does not receive an ACK message after a T0 timeout, it should retransmit the request/response message and wait for the acknowledgement accordingly. The DES should alarm when it does not receive any ACK message after five retransmits of the request/response message.
+
+When a DES sends a request message which does not receive the response after a T1 timeout, it should retransmit the request message and trigger a system alarm at the meanwhile.
+
+### 7.3.2 Message acknowledgement errors handling
+
+Table 2 in clause 9 lists the values of message acknowledgement errors in the sender system and receiver system. When the receiver recognizes an error of the sender system, an ACK with value 4XX should be sent to the sender. When a receiver error occurs, an ACK with value 5XX should be sent to the sender.
+
+### 7.3.3 Service errors handling
+
+Table 3 in clause 9 lists the values of service errors for dealing with the service request. When an error occurs in dealing with a service request, a response with a result code 6XX should be sent to the sender.
+
+# 8 Protocol specification
+
+The Simple Object Access Protocol (SOAP) defined by [W3C SOAP] is used to support information transfer on the Idd interface. [W3C SOAP] shall apply except as modified by the additional
+
+commands, results and event codes specified in this Recommendation. Unless otherwise indicated, the procedures of [W3C SOAP] (including error handling and unrecognized information handling) are unmodified. HTTP POST over TCP is required to apply in the Idd interface in this Recommendation, as per [IETF RFC 7230], [IETF RFC 7231], [IETF RFC 7232], [IETF RFC 7235].
+
+A heartbeat mechanism is required over the network layer of Idd interface to detect the status of the peer DES. During heartbeat interruption, the sending of messages shall be suspended, and all messages that have not been processed shall be automatically resent after heartbeat recovery.

+## Recommendation ITU-T Q.3902
+
+## Operational parameters to be monitored when implementing NGN technical means in public telecommunication networks
+
+# 1 Scope
+
+The concept of NGN [ITU-T Y.2001] is an evolutionary tendency in public telecommunication networks development. All stages of NGN evolution could be divided into networks which are realized by PES architecture, which employs interworking between CS and PS networks and networks whose architecture is based on IMS platform with a wide range of services and different types of content.
+
+Independent from the evolutionary state of the networks, network providers need to implement a network monitoring system which can manage the quality of network operations and prevent faults.
+
+The NGN monitoring system (NMS) has to be built in accordance with the NGN functional model and has to control all protocols implemented by it. For example, the control protocol list may include: services layer (SIP, H.323, H.248, MGCP, etc.), transport layer (MPLS, BGP, EGP, Diffserv, etc.), and application layer (Diameter, SIP, AAA, Parlay, etc.). Also in accordance with NGN evolution, the NMS could include protocols implemented by CS networks (SS7, DSS1, etc.).
+
+NMS could be also used as part of the OSS systems and take part in fault management and in performance management systems [b-ITU-T M.3060]. The monitored parameters form the fundamental data about the different layers (LLA) of the OSS architecture [b-ITU-T M.3060]. NMS could control and compare different parameters of protocols and operational interfaces and, in accordance with [ITU-T M.3010] could control all network elements and services.
+
+NMS allows the control of not only stand-alone elements, but also of different types of NGN call scenarios and maintenance parameters, which could be useful for QoS testing.
+
+As a result, NMS is an important and a basic measurement instrument which must be provided in the NGN network. NMS must be used in the model network in accordance with [ITU-T Q.3900] and is a basic requirement for testing of NGN technical means.
+
+This Recommendation describes the basic requirements of an NGN monitoring system and allows to understand what parameters have to be controlled by the NMS.

+
+NMS has to be present at all stages of the NGN evolution. Basically, NMS has to be implemented from a hybrid environment: interworking between CS and PS networks. In this case, networks will include a wide range of different types of technical means. In accordance with [ITU-T Q.3900], the set of TM has to include:
+
+- Call session control system:
+  - Media gateway controller (MGC)
+  - Proxy server SIP (PS)
+  - IP multimedia subsystem (IMS)
+- Voice and signalling transmit system:
+  - Media gateway (GW)
+  - Signalling gateway (SG)
+  - Transport network environment (TNE)
+- Application servers:
+  - Application server (AS)
+  - Media server (MS)
+  - Messaging server (MeS)
+  - Application creation environment (ACE)
+- Management and billing system:
+  - Management system (MS)
+  - Billing system (BS)
+- Access environment:
+  - NGN integrated access devices (NGN-IAD)
+  - Media gateway for legacy terminal equipment (GW-LTE)
+
+From its initial installations, NMS, based on PES architecture, has to include measurement modes of both CS protocols and PS protocols. As an example, NMS must allow measurement of CS signalling protocols (SS7, DSS1, etc.) and PS signalling protocols (SIP, H.323, H.248, MGCP, etc.)
+
+For the second step of the NMS evolution, which is based only on the IMS architecture, the NMS must implement all kinds of NGN protocols on all NGN functional architecture strata. For example, the set of protocols could include MPLS, BGP, EGP, Diffserv, Diameter, SIP, AAA, Parlay, etc.
+
+As a result, all NGN TM in accordance with the NMS evolution would be divided into two parts:
+
+### *PES NGN TM part*
+
+- Call session control system:
+  - Media gateway controller (MGC)
+  - Proxy server SIP (PS)
+- Voice and signalling transmit system
+- Management and billing system
+- Access environment:
+  - NGN integrated access devices (NGN-IAD)
+  - Media gateway for legacy terminal equipment (GW-LTE)
+
+### *IMS NGN TM part*
+
+- Call session control system:
+  - IP multimedia subsystem (IMS)
+- Voice and signalling transmit system
+- Application servers
+- Management and billing system
+- Access environment
+  - NGN terminal devices (NGN-TD)
+
+Each part could include different types of signalling protocols. The main difference between PES NGN TM and IMS NGN TM is the functionality and type of protocols implemented on it. In the PES part, the call session control system is based on the Softswitch technologies. In this case, the common issue of PES is interworking with the legacy TDM networks. The call session control system based on IMS is, on the other hand, responsible for call control between NGN terminal devices.
+
+The distribution of signalling protocols by different types of TM, which are monitored by NMS, is shown below.
+
+### *PES NGN TM part*
+
+- Call session control system (H.248, MGCP, SIP, SIP-I, SIP-T, BICC)
+- Voice and signalling transmit system (H.248, MGCP, SIP, SIGTRAN, SS7, R1, R2, DSS1)
+- Management and billing system (AAA, Diameter, SIP)
+- Access environment (MGCP, H.248, H.323, SIP)
+
+### *IMS NGN TM part*
+
+- Call session control system (SIP, SIP-I)
+- Voice and signalling transmit system (SIP, SS7, R1, R2, DSS1)
+- Management and billing system (AAA, Diameter, SIP)
+- Access environment (SIP)
+
+As illustrated, the basic set of protocols must be implemented on the initial phase (PES NGN) of NMS.
+
+The next step of NMS evolution includes the other signalling protocols and takes into account the specific signalling requirements implemented by IMS.
+
+The architecture of NMS includes different types of subsystems. Figure 1 shows the basic functional architecture of NMS. The NMS consists of the following subsystems:
+
+- SS7 monitoring subsystem;
+- SIP protocol monitoring subsystem;
+- H.248 protocol monitoring subsystem;
+- voice (transfer) service level monitoring subsystem;
+- streaming video service level monitoring subsystem;
+- service level agreements performance monitoring subsystem;
+- IP information flows monitoring subsystem (RTP/RTCP protocols level);
+- application server monitoring subsystem;
+- hardware faults and reconfiguring procedures monitoring subsystem.
+
+The signalling system monitoring subsystems shall be independent from the vendor's NGN TM (for example, MGC, PS, MG, etc.). In order to gather and initially process any other subsystem information, the vendor's NGN TM management systems shall be in use. The SNMP or NetFlow may be used as the interaction protocol among the monitoring system central elements. The message format shall be specified by the Telecommunication Administrations.
+
+The following architecture of NMS includes the two common blocks of NMS evolutionary stages (PES and IMS architecture).

+# **8 NMS common measured values**
+
+As mentioned above, NMS must include the CS protocols. In this case, the monitoring system must be built in accordance with [ITU-T Q.752].
+
+According to [ITU-T Q.752], the following categories regarding the measured values should be defined in the NMS based on PES and IMS solutions:
+
+- **fault (F):** Measurement for reporting processes and detecting problems, as well as for finding out some abnormal situations in the SS7, SIP and H.248 signalling networks, and for NGN hardware, involving its reconfiguring and restarting procedures;
+- **quality (Q):** Measurement for service level parameters intended for different traffic types involving voice and video under different services; for reporting processes; for assuming measures in providing the service level guaranteed, as well as for developing an operator's policy and strategy in the field of providing a certain service level. It should be also used to have the SLA and/or SLS performed and relevant reports drawn up;
+- **traffic (T):** Measurement for real-time traffic parameters based on the IP flows information for the purpose of identifying any unwanted and unauthorized traffic; studying any internal and external impact on network security; finding out any network abnormal events; defining when requesting the user-to-user, user-to-network, network-to-user interaction parameters; studying traffic changes trends; and conducting prevention management;
+- **accounting (A):** Measurement to estimate the reliability of accounting data;
+- **network administration and planning (N):** Measurement for SS7 and NGN networks administration including the SIP and H.248 signalling systems; make decisions on networks development and further network planning; optimizing network infrastructure enhancement investment; planning applications and services; preparing traffic data to allow planning of future networks;
+- **near-real-time measurements (R):** Measurement for finding out any faults in the network. It shall be considered supplementary to the above-mentioned measurements.
+
+## 8.1 SS7 MS NMS measured values
+
+The SS7 monitoring subsystem should provide the implementation of all the functions submitted for NMS based on PES and should be compatible with [ITU-T Q.752]. According to [ITU-T Q.752], the following categories of values measured by the SS7 monitoring subsystem NMS processes are selected:
+
+- **fault (F):** Measurements carried out to issue reports and detect faults as well as to reveal emergency situations in the SS7 signalling system;
+- **configuration (C):** Measurements carried out in the course of dynamic reconfiguration due to faults elimination or administrative actions;
+- **performance (P):** Measurements carried out to estimate a stability and a reliability of the SS7 signalling network when providing services;
+- **accounting (A):** Measurements carried out to ensure the reliability of accounting, by comparison with subscribers billing data;
+- **network administration and planning (N):** Measurements carried out to administer the SS7 signalling network, make decisions on its development and further planning;
+- **near-real-time measurements (R):** Measurements carried out to reveal emergencies in network operation; they are considered as additional to those listed above.

+## Recommendation ITU-T Q.3905
+
+## Conformance test plan for number portability requirements defined by ITU-T Q-Suppl.4
+
+## Summary
+
+Recommendation ITU-T Q.3905 describes the test specifications for compliance testing against ITU-T Q-Suppl.4 "*Number portability – Capability set 1 requirements for service provider portability (All call query and Onward routing)*". There are mandatory and optional test suites which can be used for testing of:
+
+- different network scenarios of number portability (the onward routing and all call query);
+- signaling requirements for establishing the number portability;
+- interconnection among providers and call routing between ported and non-ported end-users.
+
+Additionally, this Recommendation gives the operational procedures for organizing a particular test event.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 6 Network Scenarios
+
+[b-ITU-T Q-Suppl.4] describes three network service scenarios for implementing number portability. In accordance with the functionality, there are two groups of service scenarios:
+
+- The first group is based on the method "all call query";
+- The second is based on the method "onward routing".
+
+The first scenario deals with the originating network/exchange which is not connected directly to number portability database (NPDB). In this case, the originating network/exchange forwards a request to the initiating network/exchange to obtain routing information.
+
+The second scenario is based on the fact that the initiating network/exchange also plays the role of the originating network/exchange of the calling subscriber. In this scenario, the request for routing information has to be sent to the number portability central database (NPCDB) through the donor network/exchange.
+
+In the third scenario donor network/exchange acts as an initiating network/exchange and requests the routing information in their number portability local database (NPLDB).
+
+The first and second scenarios belong to the first group which is related to "all call query", while the third scenario belongs to the second group which is related to "onward routing".
+
+Accordingly, the signalling transfer for the methods "all call query" and "onward routing" are shown in Figures 6-1 and 6-2 accordingly [b-ITU-T E.164 Suppl.2].

The 'Originating network' has a 'Lasting relation' (solid line) to a 'Transit network' (circle) and a 'Temporary relation' (dashed line) to a 'Donor network' (circle). The 'Transit network' has a 'Lasting relation' (solid line) to a 'Recipient network' (circle).

+NOTE 1 – M: mandatory tests, O: optional tests, R: requirements which are defined by [b-ITU-T Q-Suppl.4].

+NOTE 2 – For simplifying and unification of testing procedures below, it is proposed to use the term "NPDB" which specifies number portability database in general.
+
+## 8 Test cases for the exchange of signalling information
+
+This clause presents the test cases which describe a signal information exchange between an operator-recipient network/exchange, an operator-donor network/exchange and a NPDB for two methods of number portability – "all call query" and "onward routing".
+
+The signalling information in this case includes the information of the subscriber's number, information of number porting, the routing information and indication of the subscriber party number, received from a NPDB.
+
+During the provision of all tests, the transport of voice and data must be analysed. The compliance with quality of service (QoS) key performance indicators (KPIs) e.g., [ITU-T Q.3933] must be ensured according to the national requirements or standards.
+
+NOTE – The following test cases basically describe the testing scenario for MNP services. However these cases are also possible to be used for the testing of LNP services.

+**Title:** Transit networks and exchanges scenarios
+
+**Keywords:** NPDB, transit node/exchange, call routing.
+
+#### **Purpose:**
+
+Verify the various types of transit networks/exchanges for NP.
+
+#### **Standard (criteria):**
+
+Clause 8 of [b-ITU-T Q-Suppl.4].
+
+#### **Preconditions and dependencies:**
+
+The testing model of the network contains two network scenarios:
+
+- 1) in the first scenario the transit networks/exchanges are not used between an originating network/exchange and the operator-donor's network/exchange. Also, they are not used between an initiating network/exchange and the operator-recipient's. In this regard, the routing of the voice-call from a calling party to the called party is established directly between customers;
+- 2) in the second scenario the transit networks/exchanges are used between an originating network/exchange and the operator-donor's network/exchange. Also, transit networks/exchanges are used between an initiating network/exchange and the operator-recipient's network/exchange. In this regard, the routing of the voice-call from a calling party to the called party is established through the transit networks/exchanges.
+
+#### **Test set-up:**
+
+The network configurations for these scenarios are presented in Figures 8-1 and 8-2 (the path of transmission of a voice-call is highlighted in green for method "all call query" and blue for method "onward routing"). Green and blue colours highlight the traffic ways in case of using the methods "all call query" and "onward routing". The route of SMS transmission is also available for the above methods.

+-----**Test case # A.01**-----
+
+**Title:** Standard procedure for the "all call query" method
+
+**Keywords:** Routing information, originating network/exchange, initiating network/exchange, NPDB.
+
+#### **Purpose:**
+
+Verify the routing information procedure for ported numbers for the "all call query" method.
+
+#### **Standard (criteria):**
+
+Clauses 6.1.2, 6.2.1.1 of [b-ITU-T Q-Suppl.4].
+
+#### **Preconditions and dependencies:**
+
+The originating network/exchange (OLE) which is the host of the calling party, is not connected to NPDB. The called subscriber number is ported and stored in the operator-recipient's network.
+
+#### **Test set-up:**
+
+The network configuration should be allowed to transmit a voice/data call from an initiating network/exchange to an operator-recipient's network/exchange (the path is highlighted in green). All measured data have to be collected by protocol analyser at the reference points (see Figure A.1), which are highlighted in green. The network configuration is presented in Figure A.1.
+
+![Figure A.1 – Network configuration for test case A.01. The diagram illustrates a call flow across three network domains: Initiating network/exchange, Donor network/exchange, and Recipient network/exchange. A calling subscriber in an 'Originating network/exchange' connects via a BS to an MSC in the 'Initiating network/exchange'. This MSC is linked to an SRF, which connects to an HLR and an NPCDB. The call path (indicated by a thick green line with nodes) then traverses to an MSC in the 'Donor network/exchange' (linked to its own SRF, NPLDB, and HLR) and finally to an MSC in the 'Recipient network/exchange' (also linked to an SRF, NPLDB, and HLR). From the recipient MSC, the call goes through a BS to the 'Called (ported) subscriber'. Dashed boxes group the components of each network exchange. A small label 'Q.3905(16)_FA.1' is at the bottom right of the diagram.](cbb2d311b20781a595488445ded48d0a_img.jpg)

+
+#### **Testing equipment:**
+
+- 1) the traffic analyser;
+- 2) the NPDB-based solution.
+
+#### **Test procedure:**
+
+- 1) a request from OLE for establishment of the connection to the NPDB has to be sent;  
+NOTE – In the case when the originating network/exchange has no access to NPDB, the call should be forwarded to the initiating network/exchange to verify whether the number of the called party belongs to an operator-recipient's network;
+- 2) after establishing a test call, the request from the given network/exchange has to be sent to the NPDB to verify if the number of the called party is ported. Also, the request should provide information to obtain the routing information;
+- 3) in case the called party number is ported, the NPDB should inform the initiating network/exchange and an operator-recipient's network/exchange with the routing information which is needed for further call establishment. In addition, the information might include the optional indicators of the ported number (e.g., NP ID, the name of the operator-donor, the name of the operator-recipient, number, etc.). In this regard, the test suite should be allowed to send the reply to the called party providing the necessary information for call routing;
+- 4) In case the called party number is not ported the voice-call should be routed as a normal E.164 number. The relevant reply about the status of this number has to be provided from NPDB;
+- 5) after obtaining the routing information (mostly based on the test call) the operator-recipient's network/exchange should route the voice-call, using received routing information.
+
+#### **Pass/fail criteria:**
+
+The test can be considered successful if the called party number was determined correctly by using NPDB and the connection between calling party and called party was established.
+
+The test is considered failed if one of the criteria mentioned above does not come true.
+
+-----**End of the test**-----
+
+-----**Test case # A.02**-----
+
+**Title:** Special procedures for call routing using the "onward routing" method
+
+**Keywords:** Routing information, initiating network/exchange, operator-donor network/exchange.
+
+**Purpose:**
+
+Verify the special procedures for call routing using the "onward routing".
+
+**Standard (criteria):**
+
+Clause 6.2.2 of [b-ITU-T Q-Suppl.4].
+
+**Preconditions and dependencies:**
+
+Two network configurations are possible:
+
+- 1) the initiating network/exchange and the operator-donor network/exchange are not united in a network/exchange or a part of each other;
+- 2) the initiating network/exchange and the operator-donor network/exchange are united in a network/exchange.
+
+**Test set-up:**
+
+The network configuration allow to transmit a voice call from an initiating network/exchange to an operator-recipient network/exchange (the path is highlighted in blue). All measured data have to be collected by traffic analyzer at the reference point, which are highlighted in green. The network configuration is presented on Figure A.2.
+
+![Figure A.2 – Network configuration for test case A.02. The diagram shows a call path from an originating network/exchange to a recipient network/exchange via a donor network/exchange. The path is highlighted in blue, and reference points for traffic analysis are highlighted in green. The originating network/exchange contains a calling subscriber connected to a BS, which is connected to an MSC. The MSC is connected to an SRF, which is connected to an NPCDB and an HLR. The donor network/exchange contains an MSC connected to an SRF, which is connected to an NPLDB and an HLR. The recipient network/exchange contains an MSC connected to a BS, which is connected to a called (ported) subscriber. The MSC is also connected to an SRF, which is connected to an NPLDB and an HLR. The call path is highlighted in blue, and the reference points are highlighted in green.](08e8bbb2a063a3935a0c649b39ade125_img.jpg)
+
+The diagram illustrates the network configuration for test case A.02. It consists of three main network domains: the Originating network/exchange, the Initiating network/exchange, the Donor network/exchange, and the Recipient network/exchange. The call path is highlighted in blue, and reference points for traffic analysis are highlighted in green.
+
+- Originating network/exchange:** Contains a Calling subscriber connected to a BS. The BS is connected to the Initiating network/exchange.
+- Initiating network/exchange:** Contains an MSC connected to the Donor network/exchange. The MSC is also connected to an SRF, which is connected to an NPCDB and an HLR. The MSC is connected to two BSs, one of which is connected to the Originating network/exchange.
+- Donor network/exchange:** Contains an MSC connected to the Recipient network/exchange. The MSC is also connected to an SRF, which is connected to an NPLDB and an HLR.
+- Recipient network/exchange:** Contains an MSC connected to a BS, which is connected to a Called (ported) subscriber. The MSC is also connected to an SRF, which is connected to an NPLDB and an HLR.
+
+The call path is highlighted in blue, and the reference points are highlighted in green. The diagram is labeled Q.3905(16)\_FA.2.

+
+#### **Testing equipment:**
+
+- 1) the traffic analyser;
+- 2) the NPDB-based solution.
+
+#### **Test procedure:**
+
+- 1) The test steps for the first configuration of circuit network are similar to standard procedure (which was described in previous test procedure);
+- 2) The test steps for the second configuration of circuit network will be the following:
+  - a) A request for establishing a connection between calling and called party (a test call) from an initiating network/exchange has to be sent;  
+NOTE – In the case when the initiating network/exchange and an operator donor network/exchange is a united network/exchange, the call should not be forwarded for porting verifying to the initiating network/exchange.
+  - b) in this case if the called party number is in an operator-donor network (unported subscriber number) the connection between calling and called party should be established without any additional steps. The request for establishing a connection should be directly forwarded to the called party number side (in our case – to the operator-donor network/exchange);
+  - c) in a case when the called party number is not provided by an operator-donor network/exchange (ported subscriber number) then the test call cannot be served by the given initiating network/exchange. The call will be forwarded to another initiating network/exchange or NPDB;
+  - d) after obtaining the routing information from another initiating network/exchange of NPDB-side, the operator-recipient network/exchange should route the voice call, using received routing information, to the called party in order to establish the voice call connection between subscribers.
+
+#### **Pass/fail criteria:**
+
+The test can be considered successful if the connection between calling party and called party was established correctly.
+
+Test is considered failed if the establishment of a connection between the calling party and called party was impossible.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# **6 General requirements for testing BBA networks**
+
+There are several testing stages in the functional and interoperability testing of broadband access (BBA) networks and technical means (TM). These stages include the functional testing of the BBA networks and interoperability testing of the BBA TM. The results of each of these tests shall be delivered to the global database in a format that conforms to [ITU-T Q.3903].
+
+## **6.1 Testing scheme**
+
+Tests are executed on the model network described in [ITU-T Q.3900]. The generalized testing scheme is shown in Figure 1.
+
+![Figure 1 – General scheme for BBA network testing. The diagram illustrates a symmetrical network testbed. At the top, two identical branches (A and B) consist of BRAS, AAA, DHCP, and PPPoE servers connected to an Ethernet Aggregation Switch. Each switch connects to three local hosts (Host_1, Host_2, Host_3) and an IP Network Core (Core-1 for A, Core-2 for B). Between the cores is a Network QoS parameters emulator. Below the cores, an IP Protocols Analyzer connects to a central 'Patch-panels and cross-cable equipment' block. This central block also connects to two DSLAM/MSAN/EAS/OLT units (A and B). Each DSLAM unit connects to three Home Gateways (HG1, HG2, HG3), and each HG connects to three hosts (Host_1, Host_2, Host_3).](a5ee5c23b6dc52ec1d724b76d5a5f58f_img.jpg)

+| <b>Test scheme</b>     | <p>Image: Network diagram for Test scheme. Three hosts (Host A.1, Host B.1, Host C.1) are connected to three separate home gateways (HG1, HG2, HG3). Each host is an IPoE client with an IP address (IP:xxx.x). Each gateway is a modemxDSL unit. Each gateway is connected to a central DSLAM via a PVC035(IPoE) channel. The DSLAM has three ports (Port 1, Port 2, Port 3) corresponding to the three gateways. The DSLAM is configured for IGMP transparent snooping. The DSLAM is connected to an Ethernet switch via a MG-VLAN(S-VID 1) channel. The Ethernet switch is connected to a video server (HostX.1) with IP:xx.xx.

+| <b>Initial condition</b> | 1) Prepare in the KB the specified form to be filled-in (template of daily report) which should include the date, list of tests and achieved results.<br>2) Connect equipment under test and measurement equipment in accordance with testing scheme.<br>3) For carrying out the tests, one user port on the EAS equipment (one user line) have to be used. On the user side to the network termination of given user line there should be a connection from home gateway (business) (HG1 equipment).<br>4) Hosts A.1 and A.2 are connected to HG1 equipment.<br>5) X.1 and X.2 hosts are connected to the Ethernet switch which has implemented functions of the EAS traffic aggregation.<br>6) Host A.1 uses PPPoE sessions.<br>7) Host A.2 uses IPoE sessions.<br>8) HG1 equipment work in the bridge mode (function of local DHCP server is disconnected).<br>9) IP-address for host A.1 is assigned dynamically with allocated PPPoE server or are configured manually.<br>10) For termination of PPPoE sessions from host A.1, the external router should be connected to the Ethernet switch equipment.<br>11) IP-addresses for hosts A.2, X.1 and X.2 are assigned dynamically with the allocated DHCP server or are configured manually.<br>12) HG1 equipment supports function of VLAN tags assignment according to IEEE 802.1Q standard. HG1 equipment is configured as follows: there is assigned VLAN tag "C-VID"=111 for PPPoE sessions connected with host A.1, and VLAN tag "C-VID"=222 for IPoE sessions connected with host A.2.<br>13) User port No. 1 of EAS equipment is configured as TLS port providing transparent transfer of VLAN tags assigned on user equipment.<br>14) VLAN Membership List is configured on the EAS equipment for user port No. 1. The VLAN Membership List should contain the list of C-VID identifiers which have not been related to TLS traffic transferred through user port No. 1 in an upstream direction. This list should contain "C-VID"=111. All Ethernet frames transferred upstream through user port No. 1 and not having "C-VID"=111, should be processed as TLS traffic.<br>15) On the EAS equipment should be configured the VLAN translation table according to which the Ethernet frames transferred upstream and having initial identifier "C-VID"=111 (matching VLAN Membership List) should get "S-VID"=1 identifier. Initial identifier C-VID in this case should be deleted.<br>16) On the EAS equipment there is a possibility to assign TLS "S-VID"=100 identifier for Ethernet frames which are transferred upstream through user port No. 1 and having initial IEEE 802.1Q tag, not matching VLAN Membership List. Thus initial IEEE 802.1Q tag, received from the user, remains as enclosed C-Tag.<br>17) Perform on the analyser of IP protocols for the corresponding interface and set the following filter on protocols: ICMP    ARP. |

HG1 is connected via IPoE to DSLAM/MSAN/EAS (Layer 2 DHCP Relay Agent, DHCP opt82 insertion, Port 1). DSLAM/MSAN/EAS is connected via S-VID '1' to an Ethernet switch. Host X.1 (IP: xxxxx) is also connected to the Ethernet switch. The Ethernet switch is connected to a Server DHCP (option 82) and a BRAS (IDHCP Relay Agent). Arrows show DHCP opt82 broadcast from Host A.1 to the switch, and DHCP opt82 unicast from the switch to the Server DHCP and BRAS.</p> |

+**Test scheme**
+
+The diagram illustrates a network test scheme. On the left, under 'Vendor "X"', Host A.1 (Client DHCP) is connected to HG1 (bridged mode, AT&RVTUR), which is connected to the DSLAM/MSAN via iPoE. Host B.1 (Client PPPoE) is connected to HG2 (bridged mode, AT&RVTUR), which is connected to the DSLAM/MSAN via PPPoE. The DSLAM/MSAN contains a Layer 2 DHCP Relay Agent on port 1 and a PPPoE Intermediate Agent on port 2. An Ethernet connection links the DSLAM/MSAN to the BRAS under 'Vendor "Y"'. The BRAS contains a Server PPPoE and a Server DHCP. The BRAS is also connected to a Server AAA (RADIUS). A Protocol analyzer is connected to the BRAS. Dashed lines indicate traffic paths: DHCP/PPPoE (discovery) from Host A.1 and Host B.1 through the DSLAM/MSAN to the BRAS; DHCPoption82 || PPPoE(discovery)+TAG from the BRAS to the Server AAA (RADIUS); and RADIUS traffic between the BRAS and the Server AAA (RADIUS). Filters are applied: 'filter: bootp || pppoe' on the path to the protocol analyzer, and 'filter: radius' on the path from the protocol analyzer to the Server AAA (RADIUS).

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 6 Benchmark information model
+
+In this clause, "benchmark information model" refers to the structure of the information elements that define the benchmark. This **information** model is depicted in Figure 1.
+
+The information model consists of three primary elements: use cases, which describe the behaviour of an individual user, and which in turn define scenarios; benchmark tests, which generate a workload by aggregating the behaviour of individual scenarios in a controlled manner, and collect log files of measurements during the test; and benchmark test reports, which report metrics interpreted from the benchmark test log files.

+
+The diagram illustrates the IP multimedia subsystem (IMS) benchmark information model, organized into three main columns: Use case, Benchmark test, and Test report.

+
+**Figure 1 – IP multimedia subsystem (IMS) benchmark information model**
+
+## 6.1 Use case
+
+The top level of the individual behavioural model is the use case. A use case describes: The goal that a user has in interacting with a system, the various actors (e.g., other users, network elements) that participate in the use case, the basic course of events that are carried out by the user and the SUT, the design objective (DO) of the use case, the possible outcomes that apply to the use case, and the metrics to be collected. The goal and actors of a use case are documented in narrative text and diagrams; the other elements are complex information elements, which are described in their respective clauses.
+
+### **6.1.1 Call flow**
+
+The calls flows define the characteristic message flows, the tones and announcements (TAs) for a specific interface.
+
+### **6.1.2 Load profile**
+
+To facilitate the calculation of processing capacity and the appropriate load profile, the concept of workload factor (WLF) has been defined based on the reference call (RC) for each combination of traffic case and traffic signalling interface. The RC is defined as a basic ISDN user part (ISUP) to ISUP call connected through two media gateways (MGWs) in the same domain.
+
+Based on the WLFs for all different types of calls, the call intensities and the services used, one can express the total traffic load in an equivalent number of RCs per second.
+
+The dimensioning of any type of network depends on a number of different parameters such as utilization per channel, calls per second, mean holding time (MHT), type of accesses being involved and type of services being requested.
+
+#### **6.1.3 Metrics**
+
+The metrics of a use case describe the measurements collected from the execution of a scenario attempt. Typical metrics include response times and message rates. If a scenario is selected for execution in a benchmark test, its metrics are collected. See clause 8 for more detail.
+
+#### **6.1.4 Use case outcomes**
+
+A use case outcome is a set of possible outcomes of the scenarios of a use case. An outcome may be simply "correct", it may reflect an error or failure condition, or it may reflect a correct behaviour that took an excessive amount of time to occur. An instance of a scenario that experiences an error, failure, or timeout outcome is referred to as an inadequately handled scenario attempt.
+
+#### **6.1.5 Scenarios and scenario attempts**
+
+A scenario is a trace of a path through a use case. It is analogous to "call attempt", but applies to all interactions within an IMS/PES network, different bearer and application interactions.
+
+A scenario may succeed, fail, or succeed functionally.
+
+The terms "scenario attempt" and "scenario attempts per second" are used in the present document in place of "call attempt" and "call attempts per second" because IMS is a transaction-oriented system with transactions of a variety of types traffic sets, and in the real world do not operate according to only one transaction type, so the more generalized term is necessary. It would be incorrect and misleading to attempt to report the capacity of a system in "call attempts per second", "registration attempts per second", etc., for system loads that were other than purely call attempts, registration attempts, etc.
+
+#### **6.1.6 Design objective (DO)**
+
+The DO describes the maximal acceptable rate handled scenario attempts for a use case.
+
+#### **6.1.7 Scenario**
+
+A scenario describes a single interaction sequence among the actors of a use case. It is documented by a set of preconditions on its actors (typically specified by parameter values). In the case of IMS/PES the scenario is defined as a set of different bearer capabilities (e.g., speech, 3.1 kHz audio, unrestricted digital information (UDI), unrestricted digital information with tones and announcements (UDI/TA)), services (fax, modem), or dial modes.
+
+## 6.2 Benchmark test
+
+A benchmark by definition measures the behaviour of a population of users. To accomplish this, the behaviours of individual users shall be aggregated into input traffic to the SUT. The input traffic shall be realistic, in the sense that a population of users would perform such actions in the real world, and in the sense that statistical variation in user behaviour is similar to statistical variation that would occur in the real world.
+
+### 6.2.1 Traffic set
+
+The traffic set is a collection of scenarios which are determined to be likely to co-occur in a real-world scenario. The scenarios do not need to come from the same use case. Within a traffic set, each scenario has an associated relative occurrence frequency, interpreted as the probability with which it would occur in the course of the test procedure.
+
+### 6.2.2 Background load
+
+Background load is a workload presented to the SUT in order to consume its resources. It may consist of a stream of traffic presented to the SUT by an external system apart from the test system; or it may be a workload presented to the processing elements, network, or storage subsystem of the SUT.
+
+The purpose of background traffic is to make possible the measurement of a DOC in SUT when the capacity of the test system is insufficient to reach the DOC.
+
+If a benchmark test is published in which background load is used, then the following requirements apply:
+
+- the hardware used to generate the background load shall be fully specified. If the background load is generated by software running directly on the SUT, then the components of the SUT on which the background load is executed shall be fully specified;
+- the software used to generate the background load shall be provided in source form, including makefiles and any other configuration files required to compile the software.
+
+#### 6.2.3 Traffic-time profile
+
+The traffic-time profile is a function describing the average scenario attempt arrival rate as a function of elapsed time during a benchmark test. A traffic-time profile should be chosen in such a manner so that, for a given scenario attempt arrival rate, sufficient samples are generated that metrics can be collected with an appropriate confidence bound. The following call profiler traffic patterns are used today: saw tooth, blast, ramp, steady call rate, rolling blast and Poisson distribution. To get a realistic scenario, a combination of at least two scenarios is needed.
+
+### 6.2.4 Test parameters
+
+The benchmark test parameters are used to control the behaviour of the test script. The data elements required to configure the test system are listed in Table 1.
+
+Table 1 is a non-exhaustive list of test parameters defined for the benchmark standard. The list is expected to grow over time, as additional subsystems and system configurations are developed.

+## 6.3 Benchmark report
+
+A test report is a document, with accompanying data files, that provides a full description of an execution of a benchmark test on a test system. The SUT and test system, as well as their parameters, are described in sufficient detail that an independent test site can replicate the test. The results of the test include: Data, represented as charts and data sets, depicting the behaviour of the SUT over the elapsed time of the test; reports of the relevant metrics that are conventionally used to compare benchmark results of differing SUTs; and a full description of other observations and exceptions noted during the test.
+
+## 7 System under test (SUT)
+
+The IMS performance benchmark covers benchmark tests for the video telephony and multimedia telephony (MMTel) fixed access – IMS/PES.
+
+Figure 2 depicts the IMS reference architecture. The components of the architecture are the primary building blocks, which are either defined by the IMS standard, or defined by external standards and referenced by the IMS. The links between the primary building blocks represent reference points over which the building blocks communicate with each other.
+
+The reference architecture is a logical architecture; no mapping of functional elements to hardware or software components is mandated. And conversely, IMS products as deployed in the real world do not factor neatly into the elements of the reference architecture, which complicates the process of comparing similar products with a benchmark.
+
+The problem can be simplified by observing that there are classes of products which have common subsets of reference architecture elements. For classes defined in this manner, common sets of benchmarks can be defined. The classes defined in this manner are called IMSs, or simply subsystems, and are expected to grow over time, as the IMS marketplace becomes richer.
+
+[ITU-T Q.3932.2], which is part of this multi-part deliverable, maintains a list and description of subsystems.
+
+In order to proceed from a subsystem description to a benchmark test, a complete description of all aspects of the subsystem relevant to the performance of the benchmark shall be present; this is referred to as the system configuration, or SUT configuration. This description starts with an enumeration of the elements of the reference architecture and an enumeration of all reference points that are external to the subsystem (i.e., reference points between elements within the subsystem are "internal"). However, the configuration requires a specification of the hardware elements (e.g., servers, central processor units (CPUs), network configuration and bandwidth) and software elements (e.g., operating system, database system), because even though the metrics reported by the benchmark tests are
+
+measured with respect to such metrics as total round-trip delay of messages and system capacity, the behaviour of IMSs is still an area of study and a thorough understanding of how CPU and network bandwidth utilization behaves during operation is of interest.

+### Creation of subscriber database
+
+The subscriber database is the data set required to configure the SUT in order to execute a benchmark test. Using the same data, the test system should be able to generate correct traffic.
+
+The present document does not try to specify a complete set, but rather just the subset that will ensure comparable results. All other provisioning information required for correct configuration of a SUT is to be set at the discretion of the SUT provider.
+
+One requirement for a fair benchmark is that the input data is similar for all test-runs. In order for this to happen we have two choices:
+
+- a) provide a database for the subscriber base. However, because we have to ensure scalability for the benchmark, this solution is not feasible;
+- b) provide rules to generate this data and data generators. Algorithms using random generators will be avoided for data that could possibly influence the results.
+
+# **8 Test system**
+
+The test system is used to generate the appropriate load on the SUT. The present document does not mandate any specific test system to be used, although the details of the test system shall be reported in the benchmark report.
+
+The test system should have two main functions:
+
+- traffic generation: the test system shall be able to execute use cases' scenarios following the traffic-time profile. It shall also be able to reproduce the appropriate traffic set (a mix of scenarios with a weight for each of them);
+- network emulation: optionally, network characteristics on the different interfaces should be emulated by the test system.
+
+## **9 Benchmark metrics examples**
+
+The metrics reported by a benchmark test are measured in real time during the execution of the test, or may be computed after completion of the test from event logs collected during the execution. Enclosed is a benchmark matrix based on [ETSI TS 101 563].

+
+# Interoperability testing suite for cloud-based control plane and pooled user plane of virtualized broadband network gateway
+
+## Summary
+
+Recommendation ITU-T Q.3957 aims to specify the interoperability testing suite for cloud-based control plane and pooled user plane (UP) of virtualized broadband network gateway (vBNG), which is based on the signalling requirements of vBNG in Recommendation ITU-T Q.4143. As a background, this Recommendation gives an overview of interoperability testing between the vBNG control plane (vBNG-CP) and vBNG pooled user plane (vBNG-PUP). This Recommendation also deals with interoperability testing of two target areas, including the interoperability testing between vBNG-CP and vBNG-PUP, interoperability testing between vBNG-PUPs, and all the test cases are designed around these two target areas.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, and information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+

+# **6 Overview of IOPT framework for vBNG-CP and vBNG-PUP**
+
+Virtual broadband network gateway (vBNG) serves as the access point to the provider's broadband network. Compared with the traditional vBNG architecture defined in [ITU-T Q.3719], the cloud-based control plane (CP) and pooled user plane vBNG concentrates on the reliability between vBNG-CP and vBNG-PUP. Hence, except for the basic layer 2 and layer 3 functions, the interoperability should include failure detection as well as switching of vBNG-CP and vBNG-PUP.
+
+Since [ITU-T Q.4143] defines the signalling requirements between vBNG-CP and vBNG-PUP, this Recommendation aims to verify whether the interactions are as expected as those described in [ITU-T Q.4143].
+
+There are two target areas that should be considered during interoperability testing (IOPT), as shown in Figure 6-1:
+
+- target area 1: IOPT between vBNG-CP and vBNG-PUP.
+- target area 2: IOPT between vBNG-PUPs.

+
+**Figure 6-1 – Interoperability testing areas for vBNG-CP and vBNG-PUP of vBNG**
+
+For the target area 1, the IOPT includes user accessing, failure detection and user switching under the instruction of vBNG-CP.
+
+For the target area 2, the IOPT between vBNG-PUPs include standby group switching as well as carrier grade NAT (CGN) backup switching.
+
+The test entities include vBNG-CP and vBNG-PUP, and the IOPT between the entities includes the IOPT of vBNG-CP and vBNG-PUP, vBNG-PUP and vBNG-PUP.
+
+For each target area, specific relevant test cases need to be provided to verify different capabilities in different functions. Noted that the basic test cases are described in [ITU-T Q.4064]. The test cases in this Recommendation concentrate on the new characteristics or different operation steps introduced by the pooling of vBNG-UPs. At the same time, this Recommendation follows the signalling requirements of [ITU-T Q.4143] and provides vBNG-CP and vBNG-PUP IOPT related test cases, as shown in Table 6-1.

+# 8 Interoperability testing cases between different vBNG-PUPs
+
+Here, the "warm standby group" of vBNG-PUP means a group of accessing interfaces from different vBNG-PUP with a warm standby mechanism defined in [ITU-T Q.4143].
+
+The mechanism "warm standby" of vBNG-PUP means that users' entries will be synchronized after the interface within the warm standby group is fault. The mechanism "cold standby" of vBNG-PUP means the user entries will not be synchronized, and users have to redial to be online [ITU-T Q.4143].
+
+The mechanism "warm standby" of the CGN card in vBNG-PUP means that the user entries will be synchronized to the other CGN cards within the device after the CGN card is at fault. The mechanism "cold standby" means the user entries will not be synchronized and have to be regenerated between different devices [ITU-T Q.4143].
+
+The action "switch over" means that switching after the device is at fault, "switch back" means that switching after the fault device is recovered.
+

+## NOTES
+
+1 ITU-T Recommendation Q.4 was published in Fascicle VI.1 of the *Blue Book*. This file is an extract from the *Blue Book*. While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## Recommendation Q.4
+
+# AUTOMATIC SWITCHING FUNCTIONS FOR USE IN NATIONAL NETWORKS
+
+## 1 Preamble
+
+The CCITT,
+
+*considering*
+
+(1) that a large amount of switching equipment will be installed in the next few years, especially in areas of low subscriber density;
+
+(2) the continuous rapid development of new switching techniques results in different generations of equipment having to co-exist;
+
+(3) that some degree of compatibility in the installed switching equipment is required in the world-wide automatic network;
+
+(4) that the introduction of newly developed switching systems presents Administrations with an ever increasing number of engineering, staff training, maintenance and other operational considerations,
+
+*and also considering*
+
+(5) that Recommendations originally intended for international application only are increasingly being applied to national networks, or could be so applied;
+
+(6) that many current studies are aimed at producing Recommendations primarily applicable to national networks,
+
+*recommends*
+
+the following guidelines for use by Administrations establishing national switching standards or, if desired, for updating existing standards. Each Administration may select those guidelines it deems applicable to its own situation.
+
+## 2 Automatic switching functions for use in national networks
+
+Table 1/Q.4 lists the functional switching capabilities of an exchange which will, or may in some instances, according to the role of the exchange in a network, need to be technically specified in order that the Administration concerned can be assured that the exchange will satisfy existing and foreseen future needs of the network. For the required capabilities, references are given to CCITT texts which should be taken into account when decisions on national standards are taken; some make positive recommendations, others give guidelines or background information. Table 2/Q.4 provides full titles for those referenced texts, and for others applicable to national switching, in order to provide more specific information about the subject matter.
+
+Some of the functions listed are required in all types of exchanges. Others may or may not be, according to the role of the exchange, e.g. local, combined local/transit, transit, international, etc.
+
+It is not always necessary that a precise technical specification be given, e.g., in a tender specification, for each switching function. In some instances, it may be sufficient to state the requirements broadly, possibly including desired ranges of parameter values, and to invite a tenderer to make his own specific proposals for evaluation.
+
+## 3 Requirements for ISDN
+
+As Recommendations for the ISDN are being developed concurrently, it is difficult to reference them in this Recommendation. All Recommendations relevant to the ISDN will be published in a single volume at the end of this Study Period 1981-1984 (Fascicle III.5).
+
+## **4 Requirements other than automatic switching functions**
+
+The technical specifications of the required automatic switching functions of an exchange do not, in themselves, constitute a complete specification. Other aspects possibly needing to be covered, which are particular to an exchange or to a group of exchanges and not included within the scope of automatic switching functions are:
+
+- traffic (dimensioning and service performance);
+- specifications dictated by the equipment environment (building constraints, power supplies, climatic conditions, etc.);
+- installation, including testing, acceptance, post-acceptance technical support, etc.;
+- training and documentation;
+- support of system design and software, e.g., CCITT Recommendation Z.100 (SDL) series and CCITT Recommendation Z.200 (CHILL) series.
+
+## **5 Technical cooperation possibilities**
+
+The CCITT Recommendations already established so far do not themselves suffice to cover all the points of a specification dealing with the functions to be performed by switching equipment. It is unavoidable, if national standards are to match the requirements and circumstances of a particular network, that the responsible Administration itself exercise a number of choices.
+
+An Administration seeking advice or guidance beyond that indicated in CCITT texts may, by approaching the ITU Secretariat, obtain information on the standards adopted by other Administrations.
+
+## **6 Definition of requirements in terms of services and facilities**
+
+6.1 Fundamental decisions as to range of service(s) and facilities to be provided must be made by the Administration. Descriptions and other information on the various services normally provided by a switching system may be found as indicated in the following:
+
+- types of services (GAS 6, Chapter II, § 3; Chapter III, § 3.2),
+- basic services (GAS 6, Chapter IV, § 1.2),
+- supplementary services (GAS 6, Chapter IV, § 1.4); Recommendations E.130, E.132, E.151; Supplement No. 1 to Series E Recommendations.
+
+6.2 A list of possible telephony subscriber services and facilities has been extracted from the GAS 6 Handbook, Chapter IX, § 1.3.2 and is shown in Annex A.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+
+## **6.1 General overview of ICS proforma**
+
+### **6.1.1 Purposes and structure**
+
+The purpose of this protocol implementation conformance statement (PICS) proforma is to provide a mechanism whereby a supplier of an implementation of the requirements defined in [ITU-T Q.3626 v.1] may provide information about the implementation in a standardized manner.
+
+The implementation conformance statement (ICS) proforma is subdivided into clauses for the following categories of information:
+
+- guidance for completing the ICS proforma;
+- identification of the implementation;
+- identification of the <reference specification type>;
+- global statement of conformance;
+- roles;
+- user role;
+- network role.
+
+### **6.1.2 Abbreviations and conventions**
+
+The PICS proforma contained in this Recommendation is comprised of information in tabular form in accordance with the guidelines presented in [ITU-T X.296].
+
+#### Item column
+
+The item column contains a number which identifies the item in the table.
+
+#### Item description column
+
+The item description column describes in free text each respective item (e.g., parameters, timers, etc.). It implicitly means "is <item description> supported by the implementation?".
+
+#### Status column
+
+The following notations, defined in [ITU-T X.296], are used for the status column:
+
+- m mandatory – the capability is required to be supported.
+- o optional – the capability may be supported or not.
+- n/a not applicable – in the given context, it is impossible to use the capability.
+- x prohibited (excluded) – there is a requirement not to use this capability in the given context.
+- o.i qualified optional – for mutually exclusive or selectable options from a set. "i" is an integer which identifies a unique group of related optional items and the logic of their selection which is defined immediately following the table.
+- ci conditional – the requirement on the capability ("m", "o", "x" or "n/a") depends on the support of other optional or conditional items. "i" is an integer identifying a unique conditional status expression which is defined immediately following the table.
+
+##### Reference column
+
+The reference column makes reference to [ITU-T Q.3626 v.1], except where explicitly stated otherwise.
+
+#### Support column
+
+The support column shall be filled in by the supplier of the implementation. The following common notations, defined in [ITU-T X.296], are used for the support column:
+
+- Y or y supported by the implementation.
+- N or n not supported by the implementation.
+- N/A, n/a or no answer required (allowed only if the status is n/a, directly or after evaluation of a conditional status).
+
+If this PICS proforma is completed in order to describe a multiple-profile support in a system, it is necessary to be able to answer that a capability is supported for one profile and not supported for another. In that case, the supplier shall enter the unique reference to a conditional expression, preceded by "?:" (e.g., ?3). This expression shall be given in the space for comments provided at the bottom of the table. It uses predicates defined in the system conformance statement (SCS), each of which refers to a single profile and which takes the value TRUE if and only if that profile is to be used.
+
+EXAMPLE 1: ?3: IF prof1 THEN Y ELSE N
+
+*In case of protocol, the following text should be added:*
+
+NOTE – As stated in [ITU-T X.296], support for a received protocol data unit (PDU) requires the ability to parse all valid parameters of that PDU. Supporting a PDU while having no ability to parse a valid parameter is non-conformant. Support for a parameter on a PDU means that the semantics of that parameter are supported.
+
+##### Prerequisite line
+
+A prerequisite line takes the form: Prerequisite: <predicate>.
+
+A prerequisite line after a clause or table title indicates that the whole clause or the whole table is not required to be completed if the predicate is FALSE.
+
+### **6.1.3 Instructions for completing the PICS proforma**
+
+The supplier of the implementation shall complete the PICS proforma in each of the spaces provided. In particular, an explicit answer shall be entered, in each of the support column boxes provided, using the notation described in clause 6.1.2.
+
+However, the tables containing in "user role" clause shall only be completed for user implementations, and the tables containing in "network role" clause shall only be completed for network implementations.
+
+If necessary, the supplier may provide additional comments in space at the bottom of the tables or separately.
+
+More detailed instructions are given at the beginning of the different clauses of the PICS proforma.
+
+## **6.2 Identification of the implementation**
+
+Identification of the implementation under test (IUT) and the system in which it resides (the system under test (SUT)) should be filled in so as to provide as much detail as possible regarding version numbers and configuration options.
+
+The product supplier information and client information should both be filled in if they are different.
+
+A person who can answer queries regarding information supplied in the PICS should be named as the contact person.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+If the ISC interface is not accessible it is also possible to perform the test of the AS using any network-to-network interface (NNI) (i.e., Mw, Mg, Mx) (see Figure 6.1.1-2). In case only the Gm interface is accessible this interface can be used instead for testing, but the verification of all requirements may not be possible.

+# 7 Test purposes
+
+## 7.1 Introduction
+
+For each test requirement a test purpose (TP) is defined.
+
+### 7.1.1 TP naming convention
+
+Test purposes (TPs) are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references are added to identify the actual test suite and whether it applies to the network or the user (see Table 1).
+
+**Table 1 – TP identifier naming convention scheme**

+### 7.1.2 Test strategy
+
+As the base standard [ITU-T Q.3627 v.1] contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification [ITU-T Q.4011.1 v.1]. The criteria applied include the following:
+
+- Whether or not a test case can be built from the TP is not considered.
+
+### 7.2 Test purposes for closed user group
+
+#### 7.2.1 Actions at the AS of the originating user
+
+##### 7.2.1.1 CUG without preference

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 7 Test purposes
+
+## 7.1 Introduction
+
+For each test requirement, a test purpose (TP) is defined.
+
+All protocol implementation conformance statement (PICS) items referred to in this clause are as specified in [ITU-T Q.4014.1] unless indicated otherwise by another numbered reference.
+
+### 7.1.1 TP naming convention
+
+TPs are numbered, starting at 001, within each group. Groups are organized according to the test suite structure (TSS). Additional references are added to identify the actual test suite and whether or not it applies to the network (see Table 7.1.1).
+
+**Table 7.1.1 – TP identifier naming convention scheme**
+
+|                                                                               |

+| - Identifier: TP_<group>_<nnn>                                                |
+| - <group> = group 3 digit field representing group reference according to TSS |
+| - <nnn> = sequential number (001-999)                                         |
+
+### 7.1.2 Test strategy
+
+As the base standards [ETSI TS 124 229] and [ETSI TS 183 036] contain no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification [ITU-T Q.4014.1]. The criteria applied include the following:
+
+- Whether or not a test case can be built from the TP is not considered.

+**Test purpose**  
+*486 repeated Via with different values, ACK is not sent*
+
+Ensure that the IUT, when an INVITE client transaction is in the Completed state, on receipt of new final responses with different Via branch parameter value, does not repeat its ACK request until timer D set to at least 32 second expires if an unreliable transport is used.

+##### Test purpose
+
+*404 received in proceeding state; setting of Call-ID, From headers and Request-URI*
+
+Ensure that when the client transaction is in the **Proceeding state**, that on receipt of a Not Found (404 Not Found) response, an ACK request is sent with the same Call-ID, From headers and Request-URI as in the original INVITE request and the same Tag in the To header as in this response.

+###### Test purpose
+
+*Request line in the sent BYE is set to the value of the Contact header in the received request*
+
+Ensure that the IUT, once a dialogue has been established with an INVITE request including no Record-Route header set to release it, sends a BYE request with the Request-URI set to the Contact URI included in the original INVITE request and with no Route header set.

+
+*Request line in the sent BYE is set to the value of the Contact header in the received request*
+
+Ensure that the IUT, once a dialogue has been established with an INVITE request including a Record-Route header set to a list in which the last element does not contain a lr parameter to release the call, sends a BYE request with the Request-URI set to the Contact URI and a Route header set to the list in a reverse order of the Record-Route included in the original INVITE request.

+| Ensure that on receipt of a SETUP message containing a Calling party number Address digits present and the Type of number is set to 'Unknown', Presentation Restriction Indicator is set to Presentation allowed and an INVITE request is sent.

+**Test purpose**  
+*The Userinfo of the P-Asserted-Identity is sent in a connected number. No Privacy header present or Privacy value 'none' 'from-change' tag present in the 200 OK (INVITE).*
+
+Ensure that on receipt of a 200 OK INVITE where the 'from-change' tag is present in the Supported header and no Privacy header is present, the sending of the CONNECT message is held until the UPDATE is received. If the Userinfo in the From header in the UPDATE is in the form of a tel URI containing a E.164 number a CONNECT message is sent to the calling user and a Connected number is present coded as described below.

+| Ensure that the calling party is able to set the communication on HOLD. The received reINVITE contains an a attribute in the SDP set to 'inactive'. The SUT sends a 200 OK (INVITE) containing an a attribute in the SDP set to 'inactive'. A DSS1 NOTIFY message is sent to the terminating user equipment and the Notification indicator information element is set to 'Remote hold'. The communication was previously set on HOLD by the called party. |                       |                                                          |                                                |

+###### Test purpose
+
+*INVITE received History-Info header contains more than two entries not restricted, Redirecting number sent in SETUP*
+
+Ensure that on receipt of an INVITE request and a History-Info header is present containing more than two entries and the second last entry is not escaped with a Privacy header, a SETUP is sent and the first Redirecting number address signals are derived from the URI of the second last entry of the History-Info header and the Reason of diversion is derived from the cause parameter of the last entry, the second Redirecting number address signals are derived from the URI of the first entry of the History-Info header and the Reason of diversion is derived from the cause parameter of the second entry coded as described below and in Table 7.2.5.4.2-5:
+
+###### First Redirecting number
+
+Type of number
+
+National if the URI is coded as follows sip: local-number@hostportion
+
+international if the URI is coded as follows sip: global -number@hostportion and CC is not the same as the country where the user or line is located
+
+Numbering plan identification: ISDN numbering plan
+
+Presentation indicator: **presentation allowed**
+
+Reason of diversion: **reason\_VA**
+
+Number digits:
+
+Userinfo as received in the second last URI; global-number-digits: if the country code of the URI is the same as the country where the user or line is located, the country code is removed from the Userinfo
+
+###### Second Redirecting number
+
+Type of number
+
+National if the URI is coded as follows sip: local-number@hostportion
+
+international if the URI is coded as follows sip: global -number@hostportion and CC is not the same as the country where the user or line is located
+
+Numbering plan identification: ISDN numbering plan
+
+Presentation indicator: presentation allowed
+
+Number digits:
+
+Userinfo as received in the first URI; global-number-digits: if the country code of the URI is the same as the country where the user or line is located, the country code is removed from the Userinfo
+
+###### SIP header values
+
+INVITE: History-Info:
+
+<any URI 1 (PIXIT)>index=1
+
+<any URI 2 (PIXIT); cause=any appropriate value>; index=1.1
+
+<URI set to the value of the Request URI; cause=**reason\_VA**>; index=1.1.1
+
+###### DSSI Parameter values

The SETUP contains a Facility Information Element with a DivertingLegInformation2 invoke component. The diversionCounter is derived from the number of dots in the index parameter of the last entry of the History-Info header. The diversionReason is derived from the cause parameter of the last entry as described in Table 7.2.5.4.2-6, the divertingNr is derived from the URI of second last entry and the originalCalledNr is derived from the URI of the first entry in the History-Info header. |            |                                                          |                                                               |

+| <p><b>Test purpose</b><br/> <i>The user establishes a three party conversation (Tight coupling)</i></p> <p>Ensure that when the initial party is on hold and a confirmed session with the waiting party exists, a flash hook event applies. On receipt of a notification of Register RECALL from the SUT, the SUT opens a new dialogue (D3) and sends an INVITE (flash) to an originating AS. This INVITE includes the following:</p> <ul style="list-style-type: none"> <li>• The Request URI is structured as follows: <ul style="list-style-type: none"> <li>– A user part containing "flash".</li> <li>– A domain name that together with the user part provides sufficient information for the AS Network to forward the request to the appropriate AS, based on Initial Filter Criteria stored in the user profile, e.g. "flash@pes.operator.com"</li> </ul> </li> <li>• A From header containing the public identity of the line on which the RECALL occurred.</li> <li>• An SDP offer for a speech call.</li> </ul> <p>The AGCF now awaits receipt of a 484 Address Incomplete from the originating AS, and when received the AGCF takes the following actions:</p> <ul style="list-style-type: none"> <li>• Requests the A MGW to play Dial Tone and collect one digit.</li> <li>• Sends an INVITE (D3) containing this single digit (as this is a Recall sequence with more than one active dialogue) and await receipt of 200 OK (Invite) or a failure response code. This INVITE is built in the same way as the previous INVITE except that the dialled digit replaces "flash".</li> </ul> <p>The AGCF then awaits a re INVITE (D2) with the SDP of a Media Server in the AS Network (acting as a 3 party bridge) and when received it takes the following actions:</p> <ul style="list-style-type: none"> <li>• Sends an instruction to the A MGW to change the address to which RTP packets are sent and from which they are received (e.g. it modifies the ITU-T H.248 Remote Descriptor).</li> </ul> <p>Sends a 200 OK (Invite) to the AS, awaits receipt of a BYE to end dialogue D3, and when this is received it sends a 200 OK (Bye).</p> <p><b>SIP header values</b><br/> INVITE D2-1<br/> Request-Line: flash@pes.operator.com</p> <p>INVITE D2-2<br/> Request-Line: flash@pes.operator.com</p> <p>INVITE3 (additional party)<br/> SDP<br/> a=sendrecv</p> <p>200 OK 3<br/> SDP<br/> a=sendrecv</p> <p>INVITE4 (initial party)<br/> SDP<br/> a=sendrecv</p> <p>200 OK 4<br/> SDP<br/> a=sendrecv</p> |            |                                                    |                                                             |

Receive and store the conference URI in the 200 OK response.</li> <li>• For each of the active sessions, that are requested to be joined to a three-way session, send two REFER requests with the Request URI indicating the previously received conference URI and the Refer-To header indicating the SIP URI or tel URL of the respective remote user.</li> <li>• The conference creator releases the sessions 1 and 2 after the receipt of NOTIFY requests indicating that the remote users have successfully joined the three-way session.</li> </ul> <p><b>SIP header values</b><br/> INVITE1<br/> Request Line user inactive idle stae<br/> SDP a=sendonly</p> <p>INVITE2<br/> Request Line = conference factory URI<br/> Contact: ; isfocus</p> <p>SUBSCRIBE<br/> Request URI contained the conference URI<br/> Event: conference"</p> <p>NOTIFY 1 Event contains conference; Subscription-State contains active; expires=[any value]</p> <p>REFER1<br/> Request URI indicating the conference URI<br/> Refer-to header contains URI of remote user 1</p> <p>REFER2<br/> Request URI indicating the conference URI<br/> Refer-to header contains URI of remote user 2</p> <table style="border: none;"> <tr> <td style="vertical-align: top; border: none;">NOTIFY 2</td> <td style="border: none;">Event contains conference; Subscription-State contains active<br/>message/sipfrag contains SIP/2.0 100 Trying</td> </tr> <tr> <td style="vertical-align: top; border: none;">NOTIFY 3</td> <td style="border: none;">Event contains conference; Subscription-State contains active<br/>message/sipfrag contains SIP/2.0 200 OK<br/>application/conference-info+xml contains (S1) connected, dialled-in</td> </tr> <tr> <td style="vertical-align: top; border: none;">NOTIFY 4</td> <td style="border: none;">Event contains conference; Subscription-State contains active<br/>message/sipfrag contains SIP/2.0 100 Trying</td> </tr> <tr> <td style="vertical-align: top; border: none;">NOTIFY 5</td> <td style="border: none;">Event contains conference; Subscription-State contains active</td> </tr> </table> |                                                                                                                                                                                 |                                                       |                                                             | NOTIFY 2 | Event contains conference; Subscription-State contains active<br>message/sipfrag contains SIP/2.0 100 Trying | NOTIFY 3 | Event contains conference; Subscription-State contains active<br>message/sipfrag contains SIP/2.0 200 OK<br>application/conference-info+xml contains (S1) connected, dialled-in | NOTIFY 4 | Event contains conference; Subscription-State contains active<br>message/sipfrag contains SIP/2.0 100 Trying | NOTIFY 5 | Event contains conference; Subscription-State contains active |

+| Ensure that when a terminating user in a confirmed session receives an INVITE request to another dialogue, the SUT sends a 180 Ringing. The SUT evaluates the switch order command based on a provisioned mapping table. The SOC indicates that the served user wishes the be connected to the waiting party, the AGCF performs the following actions:     |            |                                                 |                                                              |

+###### Test purpose
+
+*The terminating user rejects the waiting call*
+
+Ensure that when a terminating user in a confirmed session receives an INVITE request to another dialogue, the SUT sends a 180 Ringing. The SUT evaluates the switch order command based on a provisioned mapping Table.
+
+SOC indicates that the served user wishes to reject the waiting call, the AGCF performs the following actions:
+
+- Send a provisioned error response code (e.g. 603) to the INVITE request received from the waiting party.
+- Request the media gateway to:
+  - Set the stream mode to send-receive.
+  - Monitor the flash-hook event.
+- Send a re-INVITE request towards the held party (i.e., the party that has been held for the purpose of collecting the switching order command). The re-INVITE request is built as follows:
+  - The Request-URI is set to the held party's identity.
+  - The SDP description for the active media stream is set to a=sendrecv.

+| <p><b>Test purpose</b><br/> <i>The terminating user rejects the waiting call</i></p> <p>Ensure that when a terminating user in a confirmed session receives an INVITE request to another dialogue, the SUT sends a 180 Ringing. The SUT evaluates the switch order command based on a provisioned mapping table. SOC indicates that the served user wishes to reject the waiting call, the AGCF performs the following actions:</p> <ul style="list-style-type: none"> <li>• Send a provisioned error response code (e.g. 603) to the INVITE request received from the waiting party.</li> <li>• Request the media gateway to: <ul style="list-style-type: none"> <li>– Set the stream mode to send-receive.</li> <li>– Monitor the flash-hook event.</li> </ul> </li> <li>• Send a re-INVITE request towards the held party (i.e. the party that has been held for the purpose of collecting the switching order command). The re-INVITE request is built as follows: <ul style="list-style-type: none"> <li>– The Request-URI is set to the held party's identity.</li> <li>– The SDP description for the active media stream is set to a=sendrecv. An SDP offer for a voice call.</li> </ul> </li> </ul> <p>The AGCF also sends a re-INVITE request on the initial dialogue to hold the associated media stream.</p> <ul style="list-style-type: none"> <li>– A user part containing a provisioned prefix followed by the switching order command without the start and finish fields.</li> <li>– A domain name that provides sufficient information to the S-CSCF to forward the INVITE request to the appropriate AS, based on Initial Filter Criteria stored in the user profile, e.g. SOC- "SO (SR SI)"@pes.operator.com</li> <li>– A P-Asserted-Identity containing the public identity of the subscriber issuing the switching control command.</li> </ul> <p><b>SIP header values</b><br/> INVITE3 (initial party)<br/> Request-Line: SO (SR SI)@pes.operator.com<br/> SDP<br/> a=sendonly</p> <p>200 OK 3<br/> SDP<br/> a=recvonly</p> <p>INVITE4 (initial party)<br/> SDP<br/> a=sendrecv</p> <p>200 OK 4<br/> SDP<br/> a=sendrecv</p> |            |                                                 |                                                               |

+###### Test purpose
+
+*The terminating user decide to switch back to the initial party*
+
+Ensure that when the initial party is on hold and a confirmed session with the waiting party exists a flash hook event applies followed by a switching order command. If the value of the switching order command indicates that the initial party is to be switched back, the AGCF performs the following actions:
+
+- Send a re-INVITE request towards the held party. The re-INVITE request is built as follows:
+  - The Request-URI is set to the held party's identity.
+  - The SDP description for the active media stream is set to a=sendrecv.
+- Send a re-INVITE request towards the active party. The re-INVITE request is built as follows:
+  - The Request URI is set to the active party's identity.
+  - The SDP description for the active media stream is set to a=sendonly.
+- Request the media gateway to:
+  - Modify the Remote Descriptor of the ephemeral termination according to the SDP information associated with the held party.
+
+The AGCF also sends a re-INVITE request on the initial dialogue to hold the associated media stream.
+
+- A user part containing a provisioned prefix followed by the switching order command without the start and finish fields.
+- A domain name that provides sufficient information to the S-CSCF to forward the INVITE request to the appropriate AS, based on Initial Filter Criteria stored in the user profile, e.g. SOC- "SO (SR SI)"@pes.operator.com
+
+A P-Asserted-Identity containing the public identity of the subscriber issuing the switching control command.

+**Test purpose**  
+*The user requires the register of details of the last incoming call in a special record McidRequestIndicator is used*
+
+Ensure that the SUT is able to send an INVITE while a session is active and a flash hook event was detected. If the collected feature code indicates MCID, the Feature Manager shall request the SIP UA to send a re INVITE request towards the AS. The re INVITE request is built as follows:
+
+- the Request URI is set to the served user's identity, and
+- include no Body in the re-INVITE
+- the re-INVITE including a XML-MIME with XML mcid body with MCID XML Request schema containing a McidRequestIndicator set to 1.

+
+## Summary
+
+Recommendation ITU-T Q.4043 specifies virtual switch (vswitch) interoperability testing requirements. This Recommendation introduces an overview of a vswitch and vswitch interoperability testing . This includes, but is not limited to, the definition, characteristics and general capabilities of vswitches, as well as an overview of interoperability testing of vswitches. The description of cloud-related use cases of vswitches, given in the appendix, describes the related interaction processes. Based on an analysis of involved vswitch capabilities in cloud-related use cases, the corresponding derived requirements of a vswitch's interoperability testing are introduced.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 6 Concept of a virtual switch
+
+A virtual switch, which belongs to the resource abstraction and control function, abstracts physical network resources to enable a cloud service provider to offer virtual network capabilities for a virtual machine (VM) with capabilities of rapid elasticity, resource pooling and on-demand self-service. A virtual switch is a software implementation, which can be deployed as a part of hypervisor or as a VM. As shown in Figure 6-1, a virtual switch provides network access to the VM through the VM's virtual network interface cards (NICs), as well as network access to physical hosts through the physical NIC which is used as the uplink port of the virtual switch.
+
+NOTE 1 – A virtual switch only refers to the virtual switch used to provide connectivity for VMs in virtualized environments. Some variant implementations of a virtual switch can be used in other technical areas, such as containers, and are beyond the scope of this Recommendation.

+
+**Figure 6-1 – Overview of a virtual switch**
+
+Compared to physical switches, virtual switches have the following key characteristics:
+
+- need to provide the compatibility for computing virtualization platforms;
+- can be deployed without changing the hardware environment;
+- convenient to deploy new functions through software upgrades.
+
+Virtual switches mainly implement layer 2 (L2) network switching to meet the L2 connectivity requirements between VMs, including L2 network connectivity with VMs on the same host, and L2 network connectivity between VMs on different hosts. Virtual switches also provide additional functions for connectivity between VMs, such as virtual local area networks (LANs), traffic filtering, etc.
+
+Virtual switches are basic components of the resource layer in high-level architecture of software defined networks (SDNs) defined in [ITU-T Y.3300]. Through a tunnelling function, a virtual switch
+
+creates virtual networks decoupled from physical network. A virtual switch provides L2 network switching and layer 3 (L3) Internet protocol (IP) routing for VMs, while providing capabilities related to network isolation, quality of service (QoS) and network operation and maintenance. The virtual switch could run on mainstream server virtualization platforms. Virtual switches are basic components of an infrastructure network domain in a high-level network function virtualization (NFV) framework defined in [b-ETSI NFV-INF 003]. It provides basic network forwarding functions and advanced network functions for a VNF such as service function chain (SFC) support.
+
+NOTE 2 – SFC, defined in [b-IETF RFC 7498], is one of the key functions of a virtual switch for NFV. In SFC networks, virtual switches can serve as classifiers and as a service function forwarder (SFF) or SFF proxy nodes, which can forward or terminate network service header (NSH) [b-IETF RFC 8300] messages for service function (SF) and provide end-to-end NSH forwarding capabilities. [b-IETF RFC 7665].

+
+**Figure 7-1 – Target areas of virtual switch interoperability**
+
+Interoperability testing of a virtual switch is to verify that the virtual switch can interact with other entities as expected. As shown in Figure 7-1, according to the way a virtual switch works, there are four different target areas that need to be considered in interoperability testing (IOPT) of virtual switch as follows:
+
+- Target area 1: "**virtual switch – VM**", dealing with interaction between virtual switch and VM;
+- Target area 2: "**virtual switch – network equipment**", dealing with interaction between virtual switch and other network equipment;
+- Target area 3: "**virtual switch – management entity**", dealing with interaction between virtual switch and management entity;
+- Target area 4: "**virtual switch – computing virtualization**", dealing with interaction between virtual switch and computing virtualization.
+
+As shown in Figure 7-1, for each target area, the IOPT should verify that the virtual switch provides specific relevant capabilities, which can be classified into the following categories:
+
+- **network connectivity:** The capabilities to provide access for VMs at multiple levels of the network including link layer, network layer and transport layer. Verification of network connectivity capabilities should be considered in target area 1 and 2;
+- **network security:** Multi-level network security protection through the detection and processing of packet header information of each layer network to prevent spoofed traffic,
+
+dangerous traffic, distributed denial of service (DDOS) attacks and other threats. Verification of network security capability should be considered in target area 1 and 2;
+
+- **network QoS:** Control and manage capabilities of network resources by traffic classification, rate limiting, bandwidth grantee. Verification of network QoS capabilities should be considered in target area 1 and 2;
+  - **tunnelling:** End-to-end tunnel encapsulation capabilities to enable network communication independent of the underlying layer and provide logical isolated networks. Verification of tunneling capability should be considered in target area 2;
+- NOTE – Tunnelling can be realized base on different protocols, such as virtual extensible local area network (VXLAN), multi-protocol label switching (MPLS) over generic routing encapsulation (GRE), stateless transport tunnelling (STT), network virtualization using generic routing encapsulation (NVGRE).
+- **control plane coordination:** Cooperation with other network equipment on control plane to enable automated multi-device collaboration, such as distributed traffic processing logic, automated complex networking, etc. Additional logic centralized controllers are the usual implementation for control plane coordination. Verification of control plane coordination capability should be considered in target area 2;
+  - **reference points:** Conceptual points at the conjunction of virtual switch and management entities. Verification of reference points should be considered in target area 3;
+  - **computing virtualization compatibility:** The capability of virtual switch supporting deployment on computing virtualization and cooperation with computing virtualization. Verification of computing virtualization compatibility should be considered in target area 4.

On the left, a grey box labeled 'VSU' has an arrow labeled 'Configure network QoS' pointing to a central grey box labeled 'Virtual switch'. Inside the 'Virtual switch' box, there is a 'Configuration interface' at the top, 'QoS tagging rules' in the middle (represented by three colored squares: red, yellow, and blue), and a 'Speed limit' section at the bottom. Below 'Speed limit' is a 'queue' represented by three stacked white rectangles. Arrows connect the 'Configuration interface' to 'QoS tagging rules', 'QoS tagging rules' to 'Speed limit', and 'Speed limit' to 'queue'. From the 'Virtual switch' box, two arrows labeled 'Traffic forwarding' point to two separate grey boxes on the right: the top one is labeled 'VM' and the bottom one is labeled 'Network equipment'. A small text label 'Q.4043(19)_FTab-I.4' is located in the bottom right corner of the diagram area.</p> |

+| <b>Description</b>                | <p>VSU login the configuration interface of virtual switch for network QoS.<br/> VSU configure virtual switch to provide network QoS capabilities for VM or network devices, including those deployed in the form of virtual machines, by configuration interface. The virtual switch can be configured to classify the traffic of ports. Rate limiting can be configured for a specified port of the virtual switch. For traffic classification, the virtual switch assigns specified a QoS priority tag for received packets before forwarding. For rate limiting, the virtual switch limits the forwarding speed according to the configuration by putting the packets into queues with different priorities.</p>                                                                                                                                                                                                                                                                                                                                                                                                                                                                             |

+| <b>Figure</b>                     | <p>Image: Diagram illustrating the virtual switch use case on tunnelling. A VSU (Virtual Switch Unit) sends a 'Configure tunnelling' message to the 'Configuration interface' of a 'Virtual switch'. The 'Configuration interface' is connected to a 'tunnel' box, which is linked to a 'Tunnel forwarding flow table'. The 'Tunnel forwarding flow table' is also connected to another 'tunnel' box. This second 'tunnel' box is connected to 'Network equipment' via 'Traffic forwarding' and 'packets'. A blue arrow labeled 'Forward to other network equipment' points from the second 'tunnel' box to the 'Network equipment'. The 'Network equipment' contains its own 'tunnel' box and 'packets'.

A VSU (Virtual Switch Unit) is shown on the left, with an arrow labeled 'Configure control plan coordination' pointing to a 'Configuration interface' on a 'Virtual switch'. The 'Virtual switch' contains a 'Distributed switch/routing' block, 'L2/3 forward information', and 'SFC orchestration'. It is connected to 'Network equipment' which also contains 'L2/3 forward information' and 'SFC orchestration'. A 'Service function chain' is shown between the 'Virtual switch' and 'Network equipment'. Below this, a cloud contains two 'Virtual switch/SC/SFF' units, each connected to two 'VM/VNF' units. A red arrow points from the 'Service function chain' in the main diagram to the 'VM/VNF' units in the cloud. The diagram is labeled Q.4043(19)_FTab-I.6.</p> |

The diagram shows a VSU (Virtual Switch Unit) on the left, which is connected to a 'Deploy virtual switch into computing virtualization' action. This action leads to a 'Computing virtualization' platform on the right. Inside the platform, there are two VMs (Virtual Machines) and a 'Virtual switch'. Arrows indicate 'VM accessing to virtual switch' and 'Monitoring resource allocation' from the VMs to the virtual switch. The diagram is labeled Q.4043(19)_FTab-I.8.</p> |

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <http://www.itu.int/ITU-T/ipr/>.

+# **6 Overview of interoperability testing of BaaS**
+
+### **6.1 Introduction of BaaS**
+
+Blockchain as a service (BaaS) is defined as a cloud service category in which the capabilities provided to the cloud service customer (CSC) are the ability of setting up blockchain platforms, and developing decentralized applications using blockchain technologies [ITU-T Y.3530].
+
+As a cloud service category, BaaS supports blockchain core features based on cloud computing infrastructure, in which an integrated development environment (IDE) for users to create, develop,
+
+test, host, deploy and operate blockchain related applications is provided. Blockchain users (e.g., cloud service customers) can utilize and reuse this BaaS service platform and may focus more on the selection of consensus algorithms and smart contract programming aspects rather than rebuilding their own blockchain platform from scratch. In addition, seamless service provisioning, interoperability with other platform as a service (PaaS) services, and simple development experience are also benefits of BaaS.
+
+The ecosystem of BaaS [ITU-T Y.3530] consists of roles, sub-roles and their activities based on cloud computing reference architecture defined in [ITU-T Y.3502] as shown in Figure 6-1, including:
+
+- CSN:BaaS partner (CSN:BaaS developer);
+- CSP:BaaS provider (CSP:BaaS provider);
+- CSC:BaaS customer (CSC:BaaS customer).

+CSP:BaaS provider is the sub-role of CSP performing and managing blockchain related core features (i.e., consensus mechanism, smart contract, transaction, cryptography, peer-to-peer (P2P) connectivity, ledger management) and supporting the provision of blockchain services.
+
+CSC:BaaS customer is the sub-role of CSC performed by end users in order to use the blockchain services from the CSP:BaaS provider.
+
+## 6.2 Interoperability testing of BaaS
+
+BaaS interoperability is a capability to interact between CSP:BaaS provider and CSN:BaaS developer, CSP:BaaS provider and CSC:BaaS customer, among different CSP:BaaS providers or between CSP:BaaS provider and management entity. During the interaction, CSN:BaaS developer allocates resources to support BaaS services development, the CSC:BaaS customer interacts with BaaS services and exchange information, one BaaS service works with other BaaS services to meet the CSC:BaaS customer's demands, and the management entity of the CSP interacts with CSP:BaaS provider to manage, monitor, maintain and optimize BaaS services.
+
+BaaS IOPT is used to verify functions and interaction capabilities that realize the BaaS interoperability.
+
+As described in [ITU-T Q.4040], the interoperability testing in different cloud capabilities types is different. There are three major IOPT scenarios: infrastructure capabilities type IOPT, platform capabilities type IOPT, and application capabilities type IOPT [ITU-T Q.4040]. Since BaaS is regarded as one of the capabilities of the PaaS, BaaS IOPT should be considered as a platform capability type IOPT.
+
+According to Figure 6-2, there are 4 different target areas of IOPT of BaaS in this document as follows:
+
+- 1 "CSP:BaaS provider-CSN:BaaS developer", dealing with interactions between CSP:BaaS provider and CSN:BaaS developer.
+- 2 "CSP:BaaS provider -CSP:BaaS provider", dealing with collaboration among different CSP: BaaS providers.
+- 3 "CSP:BaaS provider-CSC:BaaS customer", dealing with interactions between CSP: BaaS provider and CSC:BaaS customer.
+- 4 "CSP:BaaS provider-management entity", dealing with interactions with CSP management functions.

CSP:BaaS provider launches service component demands to CSN:BaaS developer. CSN:BaaS developer receives the demands and provides the service design and development function including service customization, service integration, service development and service deployment to develop corresponding services. Then the corresponding distributed ledger (DL) data structure, smart contract, consensus algorithm, encryption algorithm, etc. can be supplied to CSP:BaaS provider.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |

At the top is a 'Management entity' box containing sub-functions: 'Integration', 'Security', 'Operational support systems', 'Business support systems', and 'Development function'. Below this, there are three hexagonal blocks representing 'CSP: BaaS provider A', 'CSP: BaaS provider B', and a third unnamed provider indicated by dots. Each provider contains a network of nodes labeled A, B, C, and D. A bidirectional arrow labeled 'Management instruction' connects the Management entity to the providers, indicating a flow of instructions down and status information up.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+# 6 Overview of vBNG
+
+## 6.1 Concept of vBNG
+
+A broadband network gateway (BNG) is defined as the access point to a provider's Internet protocol (IP) network for wireline broadband services [ITU-T Q.3315]. vBNG is the virtualization of a BNG by using virtualization technologies, which include network virtualization [ITU-T Y.3011] and compute virtualization technologies. Virtualization technologies aggregate multiple resources, which can be distributed in different equipment in a provider and appear as a single resource. vBNG should meet the signalling requirements between a vBNG and service platform for flexible network service combination on the BNG specified in [ITU-T Q.3315], and the on-demand service based on flexible function provision.
+
+NOTE – The service platform acts as an intermediate layer between the network services and the BNG.
+
+Cloud computing is defined in clause 3.1.5. As a virtualized network element, vBNG can be deployed in a scalable and elastic pool of shared physical or virtual resources, and can provide self-service and administration based on the management system, such as management and orchestration (MANO). vBNG belongs to cloud computing, and its IOPT is a kind of cloud IOPT. Compared to BNG, the characteristics of vBNG can be summarized as follows.
+
+- vBNG can provide such service functions as VNF, so it should provide compatibility for a network function virtualization platform.
+- vBNG can provide service functions on demand and customized functions for specific requirements such as deep packet inspection (DPI), firewall (FW) and service function chain (SFC) functions.
+- vBNG can provide flexible extensibility of a logical isolated partition to improve service capabilities. One example is that vBNG can extend a data plane by adding forwarding equipment both in virtualized and traditional forms to improve bandwidth.
+
+vBNG usually provides both layer 2 (L2) and layer 3 (L3) network functions. For L2 network functions, it includes user access services and L2 virtual private network (VPN) services, such as a virtual private local area network service (VPLS) and virtual leased line (VLL). For L3 network functions, it refers to routing and multi-protocol label switching (MPLS) services, such as L3 VPN services.
+
+vBNG often interacts with customer premises equipment/virtual customer premises equipment (CPE/vCPE) to provide user access services, and interacts with BNG/vBNG/provider edge (PE) to realize L3 network functions and L2 VPN service. In order to realize the control and management functions of network and service, a vBNG should also interact with a management system such as an operation support system/business support system (OSS/BSS) and MANO.
+
+## 6.2 Framework of vBNG
+
+The framework of vBNG in this Recommendation is shown in Figure 6-1. It consists of control and data planes.
+
+![Diagram of the vBNG framework showing control and data planes.](8e14350b4b669119a3bdfca7869110ca_img.jpg)
+
+The diagram illustrates the internal architecture of a vBNG. It is contained within a large rectangular box labeled 'vBNG' at the top. Inside this box, there are two main horizontal sections. The upper section is labeled 'vBNG control plane' and contains two smaller boxes labeled 'Control VM', with an ellipsis between them. The lower section is labeled 'vBNG data plane'. A vertical blue line separates the control plane from the data plane. At the bottom right of the diagram, there is a small text label: 'Q.4064(20)\_F6-1'.
+
+Diagram of the vBNG framework showing control and data planes.
+
+Figure 6-1 – The framework of vBNG
+
+The vBNG control plane is responsible for user access management, user management, address management, authentication management, service management, etc. The vBNG data plane is responsible for packet forwarding.
+
+NOTE 1 – User access management establishes connections with users, including point-to-point protocol over Ethernet (PPPoE), IP over Ethernet (IPoE).
+
+NOTE 2 – User management is responsible for the unified management of user authority, status and business information, such as accounting information.
+
+NOTE 3 – Address management realizes unified allocation and management of user address and service address based on local or external address pools.
+
+NOTE 4 – Authentication management achieves user authentication, which can be implemented locally or remotely. Remotely, vBNG is used as authentication agent by interacting with authentication, authorization and accounting (AAA) systems to realize authentication. Locally, vBNG acts as authentication server to provide the authentication function.
+
+NOTE 5 – Service management is responsible for management of Internet access, L2 or L3 VPN, multicast services, etc.
+
+The vBNG control plane is responsible for functions that need flexible programming of network function and elastic computing capacity, so the control plane is usually deployed as virtual machines (VMs). The vBNG data plane sometimes needs low forwarding capacity when carrying low traffic services like an integrated terminal management system (ITMS), while sometimes it requires high forwarding performance for large capacity and low latency when carrying heavy traffic and delay-sensitive services such as video and Internet protocol television (IPTV). According to the different application scenarios, there are a few kinds of implementation mode for data planes, including equipment based on the central processing unit (CPU), application specific integrated circuit (ASIC) and network processor (NP) chips.
+
+NOTE 6 – Network equipment carried by CPU chips, such as a router deployed on an x86 server, can provide flexible deployment of network functions for more open architecture. A VM is deployed on shared physical resources based on virtualization technology, thus a VM can flexibly expand of functions and performance. Based on the preceding advantages, a vBNG control plane is usually deployed as a VM to flexibly program network function and elastic computing capacity.
+
+# 7 IOPT framework of vBNG
+
+According to the framework and overview of cloud computing IOPT in [ITU-T Q.4040], which consists of interaction between cloud service customer-cloud service provider (CSC-CSP), CSP-CSP and CSP-management system corresponding to three different target areas, there also are three target areas of vBNG IOPT.
+
+- Target area A: dealing with the interaction between vBNG and access users to provide user access services.
+
+NOTE 1 – One example of target area A interaction is PPPoE or IPoE access service.
+
+- Target area B: dealing with the interaction between vBNG and BNG/vBNG/PE to provide network services.
+
+NOTE 2 – One example of target area B interaction is VPN service.
+
+- Target area C: dealing with the interaction between vBNG and a management entity to provide operation- and business-supporting capabilities.
+
+NOTE 3 – One example of target area C interaction is AAA service.
+
+Based on these three target areas, The IOPT framework of vBNG is as shown in Figure 7-1.
+
+![Diagram of the IOPT architecture of vBNG. The diagram shows a central vBNG unit connected to three external entities: CPE/vCPE on the left, BNG/vBNG/PE on the right, and a Management system at the top. The vBNG unit is divided into a 'vBNG control plane' (containing two 'Control VM' boxes) and a 'vBNG data plane'. Red lines with circled numbers indicate the interoperability test points: 1) between CPE/vCPE and the vBNG control plane, 2) within the vBNG unit, 3) between the vBNG control plane and BNG/vBNG/PE, and 4) between the Management system and the vBNG control plane. A legend at the bottom indicates that red lines represent 'Interoperability test'. The text 'Q.4064(20)_F7-1' is in the bottom right corner.](af7916c89a458fdab6c3f443217388ae_img.jpg)

+|                                   | <p>The PPPoE access process can be divided into discovery and session phases.</p> <p>1) Discovery phase<br/>vBNG establishes a PPPoE connection with CPE/vCPE and assigns a session ID to the user. In Figure I.1, the discovery phase is step 1.</p> <p>2) Session phase<br/>The session phase includes three parts: link control protocol (LCP); authentication; and network control protocol (NCP) negotiation, corresponding to steps 2-4 in Figure I.1.</p> <p>a) Step 2: The LCP stage establishes a link connection. CPE/vCPE and vBNG establish a PPP connection and then negotiate LCP configuration parameters. Only after successful LCP negotiation, will the process come to the authentication or NCP stage, it is usually an Internet protocol control protocol (IPCP) negotiation.</p> <p>b) Step 3: The authentication stage is not necessary in the PPPoE protocol. However, for network security and user management, it is necessary that service providers do it. Authentication of vBNG is usually done in two ways: locally and remotely through an AAA system (such as a RADIUS server). In local authentication, the interaction is only between vBNG and CPE/vCPE. In remote authentication, which is based on an AAA system, the interaction of this function involves CPE/vCPE, vBNG and AAA system entities. Take RADIUS authentication for example, vBNG acts as authentication agent, converses and transmits the PPPoE authentication packet from CPE/vCPE, and the RADIUS packet from the RADIUS server. In addition, authentication algorithms mainly include PAP and CHAP etc. Only once the authentication succeeds can the IPCP negotiation phase start, otherwise PPPoE access fails.</p> <p>c) Step 4: The IPCP stage assigns an IP address. CPE/vCPE and vBNG negotiate the IP address and DNS information for the user through a PPPoE configuration packet. The address allocation mode can be done in two ways: by vBNG or by DHCP server. For address management purposes, service providers often choose the second method. After this stage, vBNG configures the network interface and sync user forwarding table, thus the user can access the Internet.</p> <p>NOTE – From the logical aspect, AAA and DHCP server functions lie within the management system scope. vBNG acts as a proxy to forward user access packets to the AAA and DHCP client.</p> |

+**Figure I.2 – IPoE access process**
+
+The signalling interaction process of IPoE access service can be described as follows.
+
+#### 1) Step 1: user identification and authentication initiation
+
+- a) User terminals or CPE initiate DHCP requests with the corresponding option 60 information (it usually uses a fixed media access control (MAC) address as username to initiate requests).
+- b) Intermediate network devices label option 82 information according to relevant specifications.
+- c) On receipt of a user request message, vBNG extracts the MAC address, option 60, option 82 information, and forms a username format: MAC@Option 60. It also converts option 82 information into network access server port identifier (NAS-Port-ID) information and sends it to RADIUS authentication.
+
+NOTE – Option 82 and option 60 are both DHCP options. Option 82, which is specified in [b-IETF RFC 3046], is a relay agent information option to identify user location by carrying relay agent information in the packet. Option 60, which is specified in [b-IETF RFC 2132] is used to report manufacturer and configuration information of a terminal.
+
+#### 2) Step 2: identity authentication
+
+The RADIUS server returns a rejection message if authentication fails and vBNG terminates the user session.
+
+If authentication succeeds, vBNG sends back the authenticated information with the relevant service policy attributes of the user.
+
+#### 3) Step 3: address allocation
+
+- a) vBNG relays DHCP requests to the DHCP server for address allocation.
+- b) DHCP server assigns corresponding addresses to users according to different service information.
+- c) vBNG gets the user address and sends DHCP ACK information to the end user or CPE, and the user can surf the Internet.
+
+#### 4) Step 4: accounting
+
+- a) vBNG sends an accounting start message to the AAA system.
+- b) AAA system completes the relevant processing and sends a response message to vBNG.

+| <b>Description and illustration</b> | <p>VPN service consists of different types as described in clause 8.2, the realization principle of different VPN services also varies, but the idea is similar. In this clause, the MPLS VPN use case is taken as an example to make the description.</p> <p>MPLS VPN is the use of MPLS technology in the backbone of a broadband IP network to build an IP private network especially for enterprises, so as to achieve cross-regional, secure, high-speed, reliable communication for data, voice, image and video.</p> <p>See Figure I.3.</p> |

+| <b>Description and illustration</b> | <p>Multicast service is efficient data transmission from point to multi-point based on a multicast group management protocol (e.g., IGMP) and multicast routing protocol (e.g., PIM).</p> <p>A multicast service uses a multicast routing protocol to transfer information in a WAN and a multicast group management protocol to manage the multicast group. The typical multicast model is shown in Figure I.5, it consists of a user, vBNG and IP backbone network.</p> <div style="text-align: center;"> <p>Image: Diagram of the multicast service model. On the left, four hosts (Host A, B, C, D) are connected to a central vBNG (R). IGMP messages are shown between the hosts and the vBNG. The vBNG is connected to a central CR (R), which is part of an IP backbone cloud. The CR is connected to another CR (R), which is connected to a Source. A third vBNG (R) is also connected to the central CR. The diagram is labeled Q.4064(20)_FI.5.</p> </div> <p style="text-align: center;"><b>Figure I.5 – Multicast service model</b></p> <p>Multicast service is provided by CPE/vCPE, vBNG and vBNG/BNG/PE, the process of multicast service is as shown in Figure I.6.</p> |

+# Recommendation ITU-T Q.4078
+
+## User requirements and reference model for testbed as a service
+
+## Summary
+
+Recommendation ITU-T Q.4078 elaborates on requirements and reference model, with properties of relevance for delivering testbed as a service (TaaS) in the context of federated testbeds, aiming to complement and extend Recommendation ITU-T Q.4068. It is more particularly focused on the user interface, services, and requirements to address end-user needs when remotely accessing testbeds in order to deliver an adequate user experience. From this point, this Recommendation is reporting the elaboration of the related terms and definitions, requirements, reference model with properties of relevance for TaaS, and interoperability specifications for virtualizing and delivering modular and scalable TaaS on top of existing and future testbed infrastructures, including federated ones. Furthermore, the TaaS will be able to list the assets provided by the different testbeds and expose them through dedicated application programming interfaces (APIs) based on Recommendation ITU-T Q.4068. Generic key performance indicators (KPIs) are defined in a generic manner in the corresponding Recommendation; for instance, the exposure of capabilities is a generic KPI, so agnostic from the TaaS, and is common to all the parts of a testbed federation. Some KPIs concerning specially the TaaS are determined in this Recommendation such as dynamic discovery, availability and reputation based on a scoring of each testbed. Integration, interoperability and extensibility of the TaaS are also defined.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, and information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <https://www.itu.int/ITU-T/ipr/>.

+## 6 User requirements and reference model for testbed as a service
+
+There are two types of users to be involved in the testbed as a service (TaaS):
+
+1. The experimenters or researchers, simply called users throughout this Recommendation;
+2. The testbed providers which are responsible for the implementation and the maintenance of the TaaS.
+
+There are the following functional requirements pertaining to the TaaS users' needs:
+
+- Resource discovery: The users should be able to discover the specific resources for all available federated testbeds.
+- Resource provisioning: Mechanisms for provisioning resources by the users should be implemented, including the access and the orchestration of resources.
+- Resource configuration: The users should be able to configure the resource by changing the value or range of values of one or several parameters before an experiment.
+- Resource description: An understandable description of each resource should be provided to the users.
+- Resource reservation: Users should be able to reserve the resources in different modes such as a scheduled reservation or on-demand.
+- Experiment control and orchestration: The users should be able to control various parameters during the execution of an experiment. The users should be able to manage the full lifecycle of their experiments through a dashboard.
+- Authentication: The users should authenticate themselves to access the TaaS.
+- Authorization: The users should receive authorization to use the resources provided by the testbeds.
+- Monitoring, results gathering and reporting: The users should be able to track which parameters should be monitored during an experiment and to collect the results of the experiment, including generation of an experiment's report.
+- Interconnection of testbeds: The users should be able to select resources distributed among several testbeds.
+- User interface: The users should be able to manage their experiments through a graphical user interface (GUI).
+
+- Remote access: The users should be able to access the TaaS remotely.
+- Data analytics tools: The users should be able to use data analytics tools offered by the TaaS.
+- Experiment discovery and selection: The users should be able to find and use past experiments. A clear description of an experiment and related test suites are also required as prerequisite.
+- Experiment storage: The users should be able to store finished experiments and their results in order to execute them again later, if needed.
+- Automated experiment scheduling: The users should have the ability to automate the scheduling of experiments based on predefined criteria, such as recurring tests or experiments triggered by external events (e.g., data threshold reached, network status change).
+- Notifications and alerts: The users should be able to set up custom notifications or alerts for certain conditions (e.g., experiment status changes, resource availability, or experiment completion).
+
+The functional requirements concerning the testbed providers are:
+
+- Resource description, catalogue provisioning: The testbed providers should describe and list their testbeds in their catalogue, including the available resources and their capabilities. A common description/advertisement scheme should be applied for all the resources of all the testbeds available under publish/subscribe model.
+- Resource identification: The resources should be clearly identified by unique identifiers used across all the testbeds.
+- Resource reservation: The testbed providers should continuously update the information related to the status of the reservation of their resources.
+- Resource provisioning: The testbed providers should operate provisioning systems and expose them through open APIs/interfaces to the rest of the testbed federation.
+- Experiment control: The testbeds should be able to work with tools used to control the experiments.
+- Management of testbeds: A testbed management system should be owned by the testbed providers. A testbed provider can change the policies of the testbed management system. Network programmability and software-defined networking (SDN) solutions could be envisioned to control in fine-grained manner the interworking aspects between the testbeds.
+- Documentation: The testbed providers should make the TaaS manual publicly available. It should be updated on a regular basis.
+- Consumption of the service: The testbed providers should provide a usage and billing services which inform the users about the utilisation of the TaaS. This service should also handle the invoices to be addressed to the users.
+- Scalability: The testbed providers should ensure the scalability of the TaaS, allowing the execution of experiments to scale based on needs.
+- High availability: The testbeds should be designed with high availability, minimizing downtime and ensuring continuous service availability.
+- Access control: The system should support different user roles (e.g., administrator, researcher, testbed provider) with specific access control policies, ensuring that users can access only the resources and features they are authorized to use.
+- Artificial intelligence (AI) / machine learning (ML) integration: The TaaS should support AI/ML models to optimize resource allocation and experiment configuration, as well as help predict potential issues in experiments based on historical data.
+
+The non-functional requirements are listed below:
+
+- User-friendliness: The users should utilise the TaaS GUI according to the guidelines and the best practices in terms of user-friendliness.
+- Security and confidentiality: The TaaS should comply with relevant standards in this area, the best practices about security and the applicable regulation for data protection, such as the general data protection regulation (GDPR) and other data protection regulations. An approach following the security and privacy by design principles is recommended (e.g., the critical data shall be encrypted).
+- Visualization: The users should be able to see real-time information during the execution of an experiment. After the completion of an experiment, they should be able to have access to the results and the logs for further analysis and other purposes (e.g., downloading results). The formats of the results should be generic enough in order to be customised for various purposes.
+- Latency optimization: TaaS should minimize latency between testbed resources and experimenters' actions, especially for real-time or time-sensitive experiments, by optimizing data transfer, resource allocation, and orchestration mechanisms.
+
+For the TaaS, there are the following key performance indicators (KPIs):
+
+- Dynamic discovery: The discovery of all the resources provided by all the testbeds is realized dynamically and all the discovered resources are displayed in the TaaS GUI in real time. It will permit to evaluate the number of resources provided by the testbeds.
+- Availability: The availability of the testbeds and their resources are also shown in the TaaS GUI. It will allow the detection of problems per testbed, notably network disconnections. This KPI can be used to improve the quality of service (QoS).
+- Reputation based on testbed rating: The broker is maintaining and updating the rating of each testbed. In the same manner, the collection of the information provided by the users is done in order to rate each testbed.
+- Number of open user sessions (active or idle): This KPI permits to know how many users are currently using the TaaS.
+- Resource utilization efficiency: This KPI tracks the efficiency of resource utilization in the testbed, providing insights into over-provisioning or under-utilization of resources, which could drive cost reduction and better planning.
+
+In the context of the TaaS, a conformity assessment of testbeds should be based on some criteria such as data protection, security, audit of the components, specifications and standards including those defined in [ITU-T Q.4068]. A test tool offered by the TaaS can be used to assess whether reserved resources are in conformity with the regulation or not (e.g., data processed in different locations/countries, insufficient central processing unit (CPU) / random-access memory (RAM) or detected congestions), which can be used as evidence in reconciliations before trials on the implications of third-party testing.
+
+A tool can be declared compliant to carry out tests, for example diagnostic tests, by all the actors agreeing or having the tools recommended/prescribed by a regulator to the different stakeholders such as operators, regulators themselves, auditors, test manufacturers. An important point is to know if the tests are to be carried out and on which specification releases (4G, 5G, 6G, fibre to the home (FTTH), any type of digital subscriber line (xDSL), cloud, etc.) but also whether they comply with relevant legislations (e.g., related to cloud, AI, data protection like GDPR).

+## Recommendation ITU-T Q.4101
+
+# Hybrid peer-to-peer (P2P) communications: Tree and data recovery procedures
+
+## Summary
+
+Recommendation ITU-T Q.4101 specifies procedures for the construction and recovery of a hybrid overlay network. The hybrid overlay network constructs a data broadcast tree among peers and calibrates the topology of the overlay network whenever peers are joining or leaving. On calibrating the hybrid overlay network, it needs to be stable even during the reconstruction process. To do this, this Recommendation specifies the procedures for construction and recovery of the tree-based hybrid overlay network, and also specifies the procedures for recovering data that may be lost during the tree recovery procedures.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+

+# **6 Overview**
+
+The hybrid overlay network that is specified in [ITU-T Q.4100] maintains a tree-based hybrid overlay network, described in clause 6 of [ITU-T Q.4100], that is used for broadcasting data. Whenever a new hybrid peer joins the overlay network, it needs to be ensured that a loop does not occur within the tree-based overlay network. In order to keep the tree resilient, it needs to reconstruct the tree-based overlay network as soon as possible when any peer leaves the hybrid overlay network.
+
+[ITU-T Q.4100] classifies the type of the path into a primary path and a candidate path, and the candidate path can be further classified as follows:
+
+- Incoming candidate path: a candidate path established by a remote hybrid peer.
+- Outgoing candidate path: a candidate path established by the hybrid peer itself.
+
+The tree-based hybrid overlay network (HON) consists of hybrid peers with primary paths. To continue being resilient to any failure of peers within a tree-based hybrid overlay network, the peers in the hybrid overlay network make multiple candidate paths for rapid recovery. If any primary path of a peer fails, the peer immediately switches one of its candidate paths to a primary path. In this switching process, special consideration is also needed to avoid loops in the tree. In addition, it needs to recover data that has been lost during the tree recovery procedures. This Recommendation provides the following procedures for supporting the recovery of tree and data:
+
+- Hybrid overlay network construction procedures;
+- Hybrid overlay network recovery procedures;
+- Hybrid overlay network data recovery procedures.
+
+# **7 Procedures for hybrid overlay network construction and recovery**
+
+This clause describes procedures for building a tree-based hybrid overlay network and procedures for recovering from failures in any intermediate peer that provide data broadcasting services.
+
+The shape of a hybrid overlay network will change with every joining of a new peer. It needs to guarantee that there is no loop and provide robustness on the failure of single or multiple node failures.
+
+For fast recovery of a network, each peer establishes multiple candidate paths during the joining procedure and chooses one of them as a primary path. The primary path is used to distribute data among each other.
+
+## 7.1 Hybrid overlay network construction procedures
+
+Hybrid overlay network is constructed through (1) overlay network joining (2) overlay network participation request propagation (3) candidate path establishment through peer-to-peer connection and (4) primary path establishment process as shown in Figure 7-1.
+
+![Figure 7-1: Hybrid P2P network construction procedures. The diagram illustrates the four-step process of joining a hybrid overlay network. A new peer (P) sends a 'HOMP request: Join' to the HOMS (Hybrid Overlay Management Server). The HOMS responds with a 'HOMP response: Peer list'. Peer P then sends 'HELLO PEER' and 'ESTAB PEER' messages to existing peers (A, B, C). Existing peers respond with 'ESTAB PEER' messages. Finally, peer P sends a 'SET PRIMARY' message to one of the existing peers. The diagram shows existing peers as grid circles and joining peers as solid grey circles.

+
+### 7.1.1 Hybrid overlay network joining
+
+When a new peer joins an existing hybrid overlay network, it firstly sends a request message for joining a hybrid overlay management server (HOMS). This request message includes the following information:
+
+- peer's identifier;
+- network address information that other peers can access;
+- authentication information if necessary.
+
+The network address information describes the network address where other peers can access the peer and contains information necessary for connection establishment such as transport method (Transmission control protocol (TCP), web real-time communications (WebRTC), etc.), transmission port number, etc.
+
+On receiving this request, HOMS provides an appropriate entry peer list that contains part of the participants' list of the overlay network and issues a new *ticket-id* sequentially to the newly joining peer. This procedure ensures that all peers have a unique *ticket-id* that will be used within that overlay
+
+network, and a balanced tree shape. Through this step, an early joined peer has the *ticket-id* lower than that of the peer joining later.
+
+When it comes to selecting the entry peers, HOMS shall not compose the peer list with the peers having low *ticket-id* values to prevent the failure of joining incurred by the possibility that the peers with low *ticket-id* have already consumed their resources to establish primary paths with other peers. If the HOMS composes the peer list with the peers having high *ticket-id*, it also leads to failure of the joining procedures since the peers within the list may not yet be attached to the tree. Hence, it is important to provide an appropriate entry peer list.
+
+When a new peer joins, the HOMS sends a response message with a *ticket-id* *T* and an *entry\_peer\_list* composed of the following rules given below:
+
+![Diagram illustrating the selection of entry peers. A horizontal bar represents the 'Peers' list of length M. A segment of length K is highlighted and labeled 'Entry peer list'.

+$$\dots$$
+$$\text{PI}[\text{ROUND}(M \times R(j)/100)+K]$$
+$$]$$

A blue box indicates the starting position as ROUND(M x R(j)/100). The formula for the entry peer list is shown on the right.
+
+- PI: The full set of peers currently remaining in the overlay network, sorted by *ticket-id* in ascending order;
+- M: The number of PI's element;
+- *R(j)*: The relative position of peer within *M*, and it is expressed in percentage (%). This value is configured by an administrator of HOMS. For example, if 100 peers are currently participating and the value of *R(j)* is 80, this means the peer is located in the 80th position in the PI;
+- K: This value indicates the maximum number of peers to be included in the *entry peer list*.
+
+### 7.1.2 Participation request propagation
+
+When the newly joining peer *P(j)* receives the peer list and its *ticket-id*, it chooses one peer *P(n)* from the *entry peer list* and sends a HELLO\_PEER request message to let other peers know its participation. If *P(j)* fails to establish a connection with the chosen peer, it resumes with the next peer in the *entry peer list*. If successful, *P(j)* does not try to send the request message anymore. HELLO\_PEER request message includes the following information:
+
+- *overlay-id*: is a unique overlay identifier;
+- *ttl*: describes how many peers this message propagates up to. Whenever a peer forwards the message, it decrements this value by 1. If the decremented value is 0, the peer does not forward anymore and discards the message;
+- *conn\_num*: describes the maximum number of connections with other peers that *P(j)* wants to establish;
+- *peer's network address information*: network address information that other peers can access to *P(j)*.
+
+On receiving the HELLO\_PEER request message, *P(n)* sends a success response and adds *P(j)*'s information into its incoming candidate path list. On receiving the success response, *P(j)* adds the *P(n)*'s information into its outgoing candidate path list.
+
+If  $P(n)$  has an available capacity on its resource, it sends an ESTAB\_PEER request message to  $P(j)$  including following information:
+
+- overlay-id;
+- peer-id;
+- ticket-id.
+
+In order to prevent overhead, each peer maintains the following information and uses them to calculate its availabilities:
+
+- the number of maximum/current primary paths;
+- the number of incoming/current candidate paths;
+- the number of outgoing/current candidate paths.
+
+In addition,  $P(n)$  is also required to send the received HELLO\_PEER request message from  $P(j)$  to other peers that are connected as a primary path by conducting the following operations:
+
+- decrements the value of *ttl* if it is not zero. If the value is zero,  $P(n)$  does not send the HELLO\_PEER request message and discards the message.
+- If  $P(n)$  has multiple primary paths with other peers except for a newly established peer, it forwards the HELLO\_PEER request message to other peers.
+- If  $P(n)$  decides to send an ESTAB\_PEER request message to  $P(j)$ , it subtracts the value of *conn\_num* and divides the number of  $P(n)$ 's primary peers and replaces the *conn\_num* value of a HELLO\_PEER with the calculated value. That is, when the *conn\_num* value in the received HELLO\_PEER message from  $P(j)$  is  $N$ , and  $P(n)$  has sent an ESTAB\_PEER message, and the number of the primary path is  $P$ , the *conn\_num* value in the HELLO\_PEER request message sent to each primary peer is set to  $(N-1)/P$ . If  $P(n)$  does not have any subordinate peers that are connected as a primary path, the operation is terminated without further forwarding.
+
+Through these procedures,  $P(j)$  secures multiple outgoing candidate paths, and it sends a SET\_PRIMARY request message to the most appropriate peer among the candidate peers to establish a primary path. To select the most appropriate peer,  $P(j)$  can figure out the metrics by sending the PROBE\_PEER message to all candidate peers.
+
+On sending a PROBE\_PEER message,  $P(j)$  inserts its local timestamp into the message, and other peers respond with the timestamp embedded. When  $P(j)$  receives the response, it calculates the time difference. Figure 7-2 shows an example of a constructed shape of a hybrid overlay network.

+
+## 7.2 Hybrid overlay network recovery procedures
+
+A tree-based hybrid overlay network is a shape of a spanning tree that has no loop, and the shape needs to be maintained against any peer dynamics which means peers join and leave during service. That is, all hybrid peers are connected into a tree without a loop. Therefore, it is required that the network supports fast recovery on any possible events such as graceful leave of peer and abnormal termination of peer.
+
+When peer  $P(p)$  detects a leave of peer  $P(j)$  that is attached as a primary path, it establishes a new primary path by choosing one of its outgoing candidate paths. However, if  $P(p)$  tries to re-establish a primary connection on every candidate path, it may lead to a collapse of the tree by the occurrence of a loop. In order to prevent the loop,  $P(p)$  does not perform a recovery operation, if it has a *ticket-id* value lower than that of  $P(j)$ . If  $P(p)$  has *ticket-id* value higher than that of  $P(j)$  and it has outgoing candidate paths, it sends a SET\_PRIMARY message to the most appropriate candidate. If  $P(p)$  has no more outgoing candidate paths, it requests HOMS to send the latest *entry peer list*, and to do the same procedures with the joining procedures described in clause 7.1 except adding a *recovery* parameter into a HELLO\_PEER request message to let the other peers know that this message is for recovery. In this case, HOMS may use a different  $R(j)$  value from the value of initial joining. For example, if an entry peer selects a node in the bottom 80% at the time of initial participation, the peer may select the node in the top 20% for reconstruction.
+
+When creating an entry peer list, if there is no peer whose *ticket-id* precedes the requesting peer, the HOMS informs that the peer is at the top position by sending an empty list or an error response message. In both cases, the peer does not perform an additional operation.
+
+When  $P(n)$ , included in the entry peer list from HOMS, receives the HELLO\_PEER message having *recovery* parameter from  $P(p)$ , it adds  $P(p)$  to its incoming candidate path list. If its incoming candidate capacity is full,  $P(n)$  disconnects the incoming candidate path with the peer with the lowest *ticket-id* that is lower than  $P(p)$ 's *ticket-id* and adds  $P(p)$  to its incoming candidate path list.
+
+Figure 7-3 shows an example of a recovered network on leaving peer 4. If peer 4 of Figure 7-3 leaves, peer 0 and peer 8, which were connected as a primary path with peer 4, detects the leave event. This event can be detected by a timeout or an explicit release message from a leaving peer. Peer 0 does not perform any operation because the *ticket-id* of the leaving peer is lower than itself. Since peer 8
+
+has a higher *ticket-id*, peer 8 sends a SET\_PRIMARY message to peer 0 to establish a new primary path with peer 0.

+
+# 8 Data recovery procedures
+
+Any peer in a hybrid overlay network can be a data source. This means that data generated by any peer is propagated to all other peers. However, in the process of recovering the tree through the process described in clause 7.2, peers can generate data asynchronously, which leads to a segmentation problem where the data generated and distributed in each segment during the tree recovery process is not fully distributed all over the tree as shown in Figure 8-1.
+
+![Figure 8-1: Cache synchronization among segments after tree recovery. The diagram shows two segments, Segment 1 (nodes A, B, C, D) and Segment 2 (nodes E, F, G, H), connected by a link between D and E. In the left state, the link (D,E) is broken, marked with an orange starburst. In the right state, the link is restored, and a new primary path (highlighted in green) is shown from node C to node E. A legend at the bottom indicates: solid black line = Primary path, solid green line = New primary path. The text Q.4101(21) is also present.](410562339ce067fdc6fa41940c118658_img.jpg)

In the left state, the link (D,E) is broken, marked with an orange starburst. In the right state, the link is restored, and a new primary path (highlighted in green) is shown from node C to node E. A legend at the bottom indicates: solid black line = Primary path, solid green line = New primary path. The text Q.4101(21) is also present.
+
+Figure 8-1 – Cache synchronization among segments after tree recovery
+
+When peer E-D's primary path is cut off, the segment {E, F, G, H} and the segment {A, B, C, D} may have different cache due to the newly generated and partially distributed data packets that are not shared between segments. Even though the primary path between two segments is restored, there may be data loss between them. Hence, cache synchronization between two segments is required to complete segment merging.
+
+In order to support the segments merging, it is necessary to cache a certain amount of data transmitted and received by each peer for data recovery.
+
+This clause specifies the caching and recovery policy when creating an overlay network, caching buffer management of peers, data transmission / reception procedures, and data recovery procedures.
+
+## 8.1 Configurations on hybrid overlay network caching and recovery policy
+
+When an overlay network is being created through reference point R3 described in [ITU-T Q.4100], a peer provides two policies: caching policy and recovery policy. When a peer joins a particular hybrid overlay network, the HOMS provides the policies, and all participating peers follow the same caching and recovery policies on the same hybrid overlay network.
+
+### 8.1.1 Caching policy
+
+An owner peer that creates a hybrid overlay network specifies a caching policy that includes the following:
+
+- Minimum number of cached data(*mN\_Cache*): This parameter specifies the minimum size of caching buffer. Each peer should keep the circular queue with a size larger than the minimum value. If the value is 0, it means that the circular queue is not maintained. That is, the data recovery function is not provided. The data recovery function is disabled when data that has already been delayed is no longer valid in the delay-sensitive service such as a multimedia streaming service.
+- Minimum duration of cached data(*mD\_Cache*): This parameter specifies the retention time for cached data. Each peer guarantees a minimum retention time for each cached data.
+
+If one of the two values (*mN\_Cache*, *mD\_Cache*) is not satisfied with respect to the caching policy, the corresponding cached data can be deleted; however, the cached data can be further maintained depending on the implementation i.e., when the value of *mD\_Cache* is 10 minutes and the value of *mN\_Cache* is 100. When the 101st packet arrives at the caching buffer, the oldest cached data can be deleted from the cache even though the retention time of each data packet to be erased is less than 10 minutes. In addition, even if 15 minutes of time has elapsed while there are still 50 data packets in the circular queue, the data packet older than the specified retention time can be deleted from the cache.
+
+### 8.1.2 Recovery policy
+
+The cached data can be exchanged in two ways; push and pull method. In pull mode, a peer that needs to get cached data from another peer, requests the data specifically. In push mode, a peer holding cached data broadcasts it to another peer that does not possess the data.
+
+An owner peer that creates a hybrid overlay network specifies a recovery policy that includes the following:
+
+- **recovery-by**: When the value is set to "push", data recovery is performed only through the primary path. This is useful when 1) the real-time data is important, 2) the frequency of data occurrence is not high, and 3) the data size is not large. When this value is set to 'pull', data recovery uses both the primary path and the candidate path. The newly created data is sent along the primary path in an existing way, and only the data to be used for recovery is delivered along the candidate path. This method is useful when data latency is not important and the size of the data is relatively large.
+
+## 8.2 Data caching and recovery in the hybrid peer
+
+In a hybrid overlay network, each hybrid peer needs to store a certain amount of data in a cache for data recovery. All peers maintain a caching buffer list consisting of a set of caching buffers in the form of a circular queue for each data source, and each caching buffer includes the following information as shown in Figure 8-2:
+
+- a) Source Peer ID;
+
+- b) DataPacket includes
+- i) sequence number;
+  - ii) datetime that indicates the NTP time of being cached;
+  - iii) payload.
+
+![Diagram illustrating the Peer's cache buffer shape. It shows three circular buffers for Source PeerID #1, Source PeerID #2, and Source PeerID #3. Each buffer is a ring with a shaded segment representing cached data. A callout box for DataPacket lists its components: Sequence number, Datetime, and Payload.

+
+The diagram shows three circular cache buffers, each associated with a source peer: Source PeerID #1, Source PeerID #2, and Source PeerID #3. Each buffer is represented by a ring with a shaded segment indicating the amount of data currently cached. A callout box labeled 'DataPacket' lists its internal structure: 'Sequence number', 'Datetime', and 'Payload'. The text 'Q.4101(21)' is located at the bottom right of the diagram.

+
+Figure 8-2 – Peer's cache buffer shape
+
+If more than a certain number (or a certain size) is accumulated during the caching process, the oldest data will be deleted first. Also, if the difference between *datetime* of a cached data and the current NTP time exceeds the value of *mD\_Cache*, the cached data will be cleared.
+
+### 8.2.1 Data caching on broadcasting
+
+In a hybrid overlay network, when a peer receives a BROADCAST\_DATA message from the primary path, the peer immediately delivers the message to the other primary path. On receiving a BROADCAST\_DATA message from another peer, it checks whether the DataPacket with the same source peer ID and the same sequence number already exists in the caching buffer. If it does exist, the message is received again, and the peer does not propagate to other primary paths. Otherwise, the BROADCAST\_DATA message is propagated to another primary path and copied to the internal caching buffer. In addition, if the value of *mD\_Cache* exists in the corresponding overlay network, it records into the *datetime* of the cached DataPacket by adding *mD\_Cache* value to the current NTP time.
+
+### 8.2.2 Data recovery after re-establishment of primary path
+
+This clause describes the procedures for recovering lost data after the re-establishment of a new primary path. The recovery mode is pre-configured by an owner of the hybrid overlay network in HOMS as specified in clause 8.1.
+
+#### 8.2.2.1 Data recovery with push mode
+
+This clause describes the data recovery operation after tree recovery when the value of *recovery-by* is "push". This operation is performed when the peer establishes a primary path with another peer after one of its primary paths is disconnected. In a hybrid overlay network, each peer receives a *ticket-id* from the HOMS when joining the hybrid overlay network, which is then used for tree recovery. When the primary path is disconnected, the tree recovery operation is not performed when the disappeared peer has a *ticket-id* value higher than that of itself. However, the peer switches the
+
+candidate path to the primary path or attempts to establish a new primary path with the new peer when the peer with a lower *ticket-id* value disappears.
+
+Figure 8-3 shows procedures for data recovery when a tree is being reconstructed.
+
+![Sequence diagram illustrating data recovery procedures in push mode between two peers, P(a) and P(b).](0f985b39edc1d52ba3600c438bc8f0a5_img.jpg)
+
+The diagram shows a sequence of interactions between two peers, P(a) and P(b), represented by vertical lifelines. The sequence of messages is as follows:
+
+- 1** P(a) sends a **SET\_PRIMARY** message with *buf(a)* to P(b).
+- 2** P(b) responds with **200** with *buf(b)* to P(a).
+- 3** P(a) sends a **BROADCAST\_DATA** message with *(n)* to P(b).
+- 4** P(b) receives the message and sends a **BROADCAST\_DATA** message with *(k)* to the right (outward propagation).
+- 3** P(b) also sends a **BROADCAST\_DATA** message with *(k)* to P(a).
+- 4** P(a) receives the message and sends a **BROADCAST\_DATA** message with *(k)* to the left (outward propagation).
+
+The diagram is labeled Q.4101(21) at the bottom right.
+
+Sequence diagram illustrating data recovery procedures in push mode between two peers, P(a) and P(b).
+
+**Figure 8-3 – Data recovery procedures in push mode**
+
+- ① *P(a)* sends its buffermap *buf(a)* when sending a **SET\_PRIMARY** message by including a *cache-recovery* parameter with '*true*' value. If the parameter does not exist, it does not proceed with the data recovery hereinafter.
+- ② *P(b)* that receives a **SET\_PRIMARY** request from *P(a)* sends its buffermap *buf(b)* while sending 200 responses.
+- ③ *P(a)* and *P(b)* send data that the corresponding peer does not have using the **BROADCAST\_DATA** message just like normal propagations.
+- ④ *P(a)* and *P(b)* that have received these **BROADCAST\_DATA** messages pass the message to other primary paths as usual.
+
+Figure 8-4 shows an example of data recovery using push mode. When peer 1 disappears, peers 0, 3, 6, and 7 that have a primary path with peer 1 initiate the path recovery procedures. In the case of peer 0, since it has a *ticket-id* value lower than that of peer 1, it does not perform the recovery procedure. In contrary, peers 3, 6, and 7 have higher *ticket-id* values, so one of the candidate paths they have secured should be converted to a primary path by sending a **SET\_PRIMARY** message. Peers 3, 6 and 7 send their buffermap using response messages of **SET\_PRIMARY**, and then peers 2, 0, and 4 send the **BROADCAST\_DATA** message with the data that peers 3, 6 and 7 do not possess.

+In addition, peers 2, 0, and 4 transmit the received *BROADCAST\_DATA* messages to synchronize data to the opposite direction simultaneously. Peers 3, 6 and 7 that receive the *BROADCAST\_DATA* message deliver it to other peers A, B, C, and D that have a primary path with them. Through these procedures, data synchronization among the segments is finished.
+
+#### 8.2.2.2 Data recovery with pull mode
+
+This clause describes the data recovery operation when the recovery-by value is "pull". According to the construction procedures specified in clause 8.1, the *ticket-id* of a peer's primary peer and candidate peer is designed to be higher than its own *ticket-id*. That is, candidate peers connected to a specific peer have *ticket-ids* lower than that of the specific peer. On establishing a new primary path, the peer with the higher *ticket-id* retrieves the lost data by the pull method, and the lower peer recovers by the push method as specified in clause 8.2.2.1. This clause describes the pull method in detail in accordance with Figure 8-5.

A label 'Q.4101(21)' is at the bottom right.
+
+**Figure 8-5 – Data recovery procedures in pull mode**
+
+When a new primary path is established, the peer recovers the lost data with the following steps:
+
+- ①  $P(a)$  sends a SET\_PRIMARY request message that does not contain its buffermap to  $P(b)$ .
+- ②  $P(a)$  sends a BUFFERMAP request message including its buffermap to other primary paths and candidate paths connected to it.
+- ③ All the peers that receive the BUFFERMAP message send 200 responses with their own buffermap.
+- ④  $P(a)$  preferentially sends a GET\_DATA request message to candidate peers to request data that they do not have, and if there is data not acquired from candidate peers, it requests the primary peer. That is, by comparing the buffermap collected from all peers, requesting data that they do not have, and when both the candidate peer and the primary peer have it, the candidate peers are used first.
+
+$P(b)$  transmits data that the other peer does not have through the BROADCAST\_DATA request message when there is no data held by  $P(a)$ . That is, push mode is used to send to a peer whose *ticket-id* value is lower than itself.
+
+When one peer goes out, peers connected to the primary path perform tree recovery and data recovery at the same time. In this process, duplicated data can be propagated along the tree. Therefore, before transmitting to the lower level, it is checked whether the corresponding data already exists in its buffer map, and if not, it is cached in its cache buffer. If it already exists, the data is not distributed. This is a safeguard to minimize the spread of duplicated data.
+
+Figure 8-6 shows procedures for data recovery using pull/push mode. When peer 1 disappears, peers 0, 3, 6, and 7, which are connected to the primary path with peer 1, initiate path recovery procedures. In the case of peer 0, since it has a lower value than peer 1, no additional action is performed, and peers 3, 6 and 7 convert one of the secured candidate paths to a primary path. Data generated in the segment {3}, {6, C, D} and {7, A, B} when the tree is being disconnected is propagated to all segments through peers 2, 0 and 4. In these processes, peers 3, 6, and 7 figure out the list of data they do not have through the buffermap exchanges with peers 2, 0, and 4, and request the data to the peers
+
+connected to the candidate path parallelly. The peer that received the recovered data completes all segment synchronization by passing it to other peers connected as the primary path.

+### 8.2.3 Data synchronization of a new peer
+
+When a new peer joins a hybrid overlay network, it needs to fully synchronize its caching buffer with other peers after establishing a primary path. Since the new peer may have multiple candidate paths and one primary path. It can make use of candidate paths for fetching data using pull mode and use the primary path for receiving newly generated latest data from the tree. Figure 8-7 shows procedures for filling the cache buffer of a newly joining peer. In this Figure, it is assumed that  $P(a)$  has candidate paths with  $P(b)$ ,  $P(c)$ ,  $P(d)$  and  $P(e)$ .

+# Hybrid peer-to-peer (P2P) communications: Signalling requirements for data streaming services
+
+## Summary
+
+Recommendation ITU-T Q.4104 describes the signalling requirements for data streaming services over hybrid peer-to-peer networks. The hybrid overlay network may have multiple data sources which send different types of data. Thus, source peers and peers conduct the several specific operations for data streaming over hybrid peer-to-peer communications, and those operations define the requirements for the relevant protocols such as overlay management protocol and peer protocol. This Recommendation includes service architecture for data streaming services over hybrid peer-to-peer networks, high-level procedures and signalling requirements for the relevant protocols.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, and information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <http://www.itu.int/ITU-T/ipr/>.

+
+# 3 Definitions
+
+## 3.1 Terms defined elsewhere
+
+This Recommendation uses the following terms defined elsewhere:
+
+**3.1.1 fragment** [b-ITU-T X.609]: A piece of the shared content.
+
+**3.1.2 hybrid overlay network** [ITU-T Q.4100]: A peer-to-peer overlay network that participating peers use to exchange data applying the pull and push method. The hybrid overlay network also provides a way to organize and maintain a tree-style path for pushing data to all peers without loops, as well as obtaining data from other peers simultaneously.
+
+**3.1.3 hybrid peer** [ITU-T Q.4100]: A peer capable of exchanging data using the mesh-based and tree-based methods running over a hybrid overlay network.
+
+**3.1.4 overlay network** [b-ITU-T X.1162]: An overlay network is a virtual network that runs on top of another network. Like any other network, the overlay network comprises a set of nodes and links between them. Because the links are logical ones, they may correspond to many physical links of the underlying network.
+
+**3.1.5 peer-to-peer (P2P)** [b-ITU-T Y.2206]: A system is considered to be P2P if the nodes of the system share their resources in order to provide the service the system supports. The nodes in the system both provide services to other nodes and request services from other nodes.
+
+NOTE– Peer is the node in a P2P system.
+
+## 3.2 Terms defined in this Recommendation
+
+None.
+
+# 4 Abbreviations and acronyms
+
+This Recommendation uses the following abbreviations and acronyms:

+
+# 5 Conventions
+
+In this Recommendation:
+
+- The keywords "is required to" indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed.
+- The keywords "is recommended" indicate a requirement which is recommended but which is not absolutely required. Thus, this requirement need not be present to claim conformance.
+- The keywords "can optionally" indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendor's implementation must provide the option, and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with this Recommendation.
+
+# 6 Overview
+
+A data streaming service is a service for delivering data which a data source generates continuously or for a specific event. The types of deliverable data include binary data, text data, etc., which each data source generates. This differs from audio or video frames in multimedia streaming services, as each data stream generated by the data source in the data streaming service can be processed independently. For example, a data source can continuously generate data which is composed of text in a predefined format such as humidity or temperature of a certain place.
+
+[b-ITU-T X.609.10] defines signalling requirements for data streaming services over managed peer-to-peer (MP2P) networks which consider mesh topology only. In a hybrid peer-to-peer (HP2P) network, one or more source peers connected with data sources organize a CoreTree. Then sub-meshes or subtrees can be organized for streaming data. Thus, this Recommendation considers signalling requirements over a data streaming service over multiple types of networks, including tree topology and mesh topology and also considering interoperation between two types of networks. Figure 6-1 shows an example configuration of a data streaming service over an HP2P network. Each source peer may have different types of data, and each source peer can be a source of a sub-mesh or a subtree.

+## 7.1 Procedures for data streaming service over HP2P network
+
+Figure 7-1 shows an overall procedure for a data streaming service over an HP2P network. As shown in Figure 7-1, the data streaming service is composed of three phases: initiation, distribution and termination.
+
+![Sequence diagram showing the overall procedure for data streaming service over HP2P network. The diagram is divided into three phases: Initiation, Distribution, and Termination.

+
+The diagram illustrates the interaction between various components during a data streaming service over an HP2P network, organized into three distinct phases:
+
+- Initiation phase:**
+  - The **Data source** sends a message to the **Source peer**.
+  - The **Source peer** interacts with **HOMS** to perform **Overlay network creation**.
+  - Subsequently, **CoreTree organization** occurs between the **Source peer** and the **CoreTree** (represented as a stack of **Peer** boxes).
+- Distribution phase:**
+  - The **Data source** sends **Data ingestion** to the **Source peer**.
+  - The **Source peer** then performs **Data distribution for CoreTree**, **Data distribution for SubMesh**, and **Data distribution for SubTree**, interacting with each respective stack of **Peer** boxes.
+- Termination phase:**
+  - The **Source peer** sends **Overlay network termination** to **HOMS**.
+  - Finally, **Overlay network termination for SubMesh and SubTree** occurs between the **Source peer** and the corresponding **SubMesh** and **SubTree** stacks of **Peer** boxes.

+
+**Figure 7-1 – Overall procedure for data streaming service over HP2P network**
+
+### 7.1.1 Initiation phase
+
+In the initiation phase, an HP2P service provider prepares a streaming session by establishing a P2P network corresponding to the streaming session. A data source commands a source peer to create a streaming session. Then the source peer creates an overlay network that is the CoreTree by interacting with the hybrid overlay management server (HOMS). When a second data source needs to join the streaming session, which means that the second data source will generate a data stream pertaining to the data stream from the first data source, the second data source commands a source peer that may be different from the source peer linked to the first data source to join the streaming session as a member of the CoreTree.
+
+NOTE – Each source peer in a CoreTree becomes a source peer of either a SubTree or SubMesh.
+
+### 7.1.2 Distribution phase
+
+In the distribution phase, a data source sends a data stream to its source peer. The source peer injects the received data stream into the overlay network. The data stream will be distributed along with the CoreTree. If the source peer receiving the data stream is acting as a source peer of either the SubTree or SubMesh, the source peer sends the received data stream to the peers in a corresponding subnetwork, which is either SubTree or SubMesh.
+
+### **7.1.3 Termination phase**
+
+In the termination phase, the HP2P service provider can terminate a specific overlay network by interacting with the HOMS. The termination does not depend on a request from a specific data source, since multiple source peers linked to corresponding data sources can belong to an overlay network. A source peer can leave a streaming session according to the command from the linked data source, and every source peer leaving a streaming session shall notify the HOMS that it is leaving. The HOMS may terminate a streaming session and remove the corresponding overlay network, if no source peer is in the CoreTree.
+
+## **7.2 Roles of HP2P components for data streaming services**
+
+### **7.2.1 Data source**
+
+The data source generates a data stream and sends the generated data stream to one or more source peers. To send the data stream to the source peer, a signalling protocol such as [b-ITU-T X.609.8] can be used.
+
+### **7.2.2 Source peer**
+
+The source peer is responsible for encapsulating the data stream into a BROADCAST\_DATA message and sending the encapsulated data stream to H-PEERs with a primary connection relationship.
+
+### **7.2.3 H-PEER**
+
+H-PEERs forward the received encapsulated data stream to other H-PEERs with a primary connection relationship.
+
+### **7.2.4 HOMS**
+
+The HOMS manages the information about the overlay network. The information of each overlay network includes network information of peers including the source peer and H-PEERs in each overlay network. As part of the information about the overlay network, the HOMS also manages session information for data streaming sessions, such as title and human-readable descriptions.
+
+### **7.2.5 CoreTree**
+
+The CoreTree is composed of the peers which can broadcast their data at any time. Thus, the CoreTree is a backbone of HP2P networks for data streaming services.
+
+### **7.2.6 SubTree**
+
+The SubTree is composed of one source peer as a root node and other peers. The source peer gets data from one of the peers of the CoreTree and delivers the data to its child nodes. Then the data is broadcast along with the tree hierarchy of the SubTree. Thus, the SubTree is a distribution network of an HP2P network for data streaming services.
+
+### **7.2.7 SubMesh**
+
+The SubMesh is composed of one source peer as a root node and other peers. The source peer gets data from one of the peers of the CoreTree and delivers the data to its neighbouring nodes. Then the data is shared among peers in the SubMesh with the pull/push-pull method. Thus, the SubMesh is another type of distribution network of an HP2P network for data streaming services.
+
+# **8 Signalling requirements of each reference point**
+
+This clause describes the requirements to be considered in developing relevant protocols for providing data streaming services. This Recommendation assumes that any other existing protocols and its combinations can be used if they can meet the requirements that are listed in this clause.
+
+## **8.1 Signalling requirements of reference point R1 (HOMS-source peer)**
+
+Through reference point R1, a peer interacts with the HOMS to join a particular HP2P network and get a list of H-PEERs in the network.
+
+The following are requirements for reference point R1:
+
+When a source peer creates a data streaming session, it is required to create a corresponding overlay network by interacting with the HOMS. The HOMS responds with an identifier of the new overlay network, if the request from the source peer is accepted.
+
+HS-01: R1 is required to enable the HOMS to allow a source peer to create a new overlay network corresponding to a new data streaming session.
+
+HS-02: R1 is required to enable the HOMS to provide a unique identifier for the new overlay network if the request from the source peer is accepted.
+
+HS-03: R1 is required to enable the HOMS to provide the refresh expiration time for each overlay network and remove the overlay network if no refresh message from the corresponding source peer is received prior to the expiration time.
+
+HS-04: R1 is recommended to enable a source peer to send a refresh message prior to the expiration time for preventing the removal of its overlay network.
+
+To create a closed session, a source peer can specify a list of peers which are eligible to join the session or a password to be used for joining the session.
+
+HS-05: R1 is required to enable a source peer to provide a peer list when the source peer creates a closed session where only particular H-PEERs can join.
+
+NOTE – The peer list includes a set of peer identifiers.
+
+HS-06: R1 is required to enable a source peer to provide security information such as a password when the source peer creates a closed session where only the peers with the predefined password can join.
+
+## **8.2 Signalling requirements of reference point R2 (Source peer-H-PEER)**
+
+Through reference point R2, peers including a source peer and H-PEERs interact with each other for streaming data.
+
+HH-01: R2 is required to enable an H-PEER to request other H- PEERs to send fragments when they have the fragment which the peer needs.
+
+HH-02: R2 is required to enable an H-PEER to send fragments to a requesting H- PEER, if it can send the requested fragments.
+
+Various transport protocols can be used when peers interact with each other.
+
+HH-03: R2 is required to support TCP as a transport protocol.
+
+HH-04: R2 can optionally support WebRTC to interact with each peer running as a web application.
+
+## **8.3 Signalling requirements of reference point R3 (H-PEER-M-PEER)**
+
+Through reference point R3, H-PEERs and M-PEERs interact with each other for streaming data.
+
+HM-01: R3 is required to enable an H-PEER/M-PEER to request M-PEERs/H-PEERs to send fragments when they have the fragment which the peer needs.
+
+HM-02: R3 is required to enable an H-PEER/M-PEER to send fragments to a requesting peer that is either an H-PEER or an M-PEER, if it can send the requested fragments.
+
+Various transport protocols can be used when peers interact with each other.
+
+HM-03: R3 is required to support TCP as a transport protocol.
+
+HM-04: R3 can optionally support WebRTC to interact with each peer running as a web application.
+
+## **8.4 Signalling requirements of reference point R4 (Data source-source peer)**
+
+Through reference point R4, a data source gathers data from various devices like IoT devices and sends the data to a certain source peer. It is also possible for data sources to send data directly to the source peer, if the data sources can generate data. The source peer then shares the received data with other peers instantly through reference point R2 or R3. Unlike multimedia streaming and content distribution services, multiple data sources can exist at the same time within an overlay network.
+
+DS-01: R4 is required to enable a source peer to receive data from various sources, and convert them to a specified format to be distributed over an overlay network in a unified manner.
+
+DS-02: R4 is recommended to enable a source peer to accommodate multiple data sources at the same time.
+
+DS-03: R4 is required to enable a data source to provide its identifier to the source peer.
+
+DS-04: R4 is required to enable a source peer to be able to identify multiple data sources using their identifiers.
+
+DS-05: R4 is required to enable a data source to register itself on a source peer as its initiation operation.
+
+DS-06: R4 is required to enable a source peer to support the registration of data sources.
+
+DS-07: R4 is required to enable a data source to send its data to a source peer which the data source registered.

+
+## Distributed data storage over HP2P network
+
+(This appendix does not form an integral part of this Recommendation.)
+
+## I.1 Introduction
+
+A data streaming service is a service for delivering multiple independent data streams which a data source generates continuously or for a specific event. Among the various types of data, there is data to be stored for data analysis. The data can be stored in local dedicated servers or the cloud servers of a certain cloud service. Instead of using dedicated servers or cloud services which incur monetary costs, possibly linear to the volume of total data, voluntary devices can store the data. The voluntary devices are geographically distributed and thus the distribution of devices can prevent a single failure of service. However, sending data to each voluntary device may have a huge burden on the data source devices. To reduce the delivery burden, data source devices and voluntary device can be attached to a hybrid peer-to-peer (HP2P) network. Data source devices send data to peers in the HP2P network once and then the peers in the P2P network spread to voluntary devices.
+
+## I.2 Scenario
+
+Figure I.1 shows an example configuration of distributed data storage. One or more data source devices can attach to an HP2P network. When multiple data source devices attach to an HP2P network, they can be connected to distinct hybrid peers or to a single hybrid peer. To store the data, at least one storage device needs to be attached to the HP2P network. When a storage device voluntarily attaches to the HP2P network by connecting to a hybrid peer in the HP2P network, it needs to interact with a management server, depicted as "Mgmt server" in Figure I.1, for registration. After the registration, data source devices can be aware of the availability of storage devices by interacting with the management server. With this awareness, data source devices start data streaming to a connected hybrid peer(s). When a hybrid peer which is connected to any storage device receives a data stream, it forwards the data stream to the attached storage device(s).

+
+Figure I.1 – Example configuration of distributed data storage
+
+Each storage device needs to report to the management server on the status of its stored data. The report may include: 1) its ID, 2) the sequence number of the first data stored, 3) the sequence number of the last data stored. On the basis of the reported information, the management server can provide a list of storage devices which store a specific range of data. In other words, any device which wants to access the stored data for analysis interacts with the management server to get the list of storage devices. Then the device can connect to any storage device on the list to get the data.

+# Hybrid peer-to-peer (P2P) communications: Signalling requirements for feature-based video services
+
+## Summary
+
+Recommendation ITU-T Q.4105 specifies signalling requirements for feature-based video services. The feature-based video services share features rather than fully encoded video data. The feature is used to recreate images at the remote end points connected to a hybrid overlay network. Since the hybrid overlay network constructs a backbone tree for distributing live data asynchronously, it can be used for video streaming, virtual conference, metaverse, etc. This Recommendation specifies signalling requirements for developing protocol specifications.

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, and information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <http://www.itu.int/ITU-T/ipr/>.

+# 3 Definitions
+
+## 3.1 Terms defined elsewhere
+
+This Recommendation uses the following terms defined elsewhere:
+
+**3.1.1 hybrid overlay network** [ITU-T Q.4100]: A peer-to-peer overlay network that participating peers use to exchange data applying the pull and push method. The hybrid overlay network also provides a way to organize and maintain a tree-style path for pushing data to all peers without loops, as well as obtaining data from other peers simultaneously.
+
+**3.1.2 hybrid peer** [ITU-T Q.4100]: A peer capable of exchanging data using the mesh-based and tree-based methods running over a hybrid overlay network.
+
+**3.1.3 peer-to-peer (P2P)** [b-ITU-T Y.2206]: A system is considered to be P2P if the nodes of the system share their resources in order to provide the service the system supports. The nodes in the system both provide services to other nodes and request services from other nodes.
+
+NOTE – Peer is the node in a P2P system.
+
+## 3.2 Terms defined in this Recommendation
+
+This Recommendation defines the following term:
+
+**3.2.1 feature:** A measurable and descriptive characteristic of content that represents an interesting part of an image, providing task-relevant information in computer vision and captured in an n-dimensional feature vector for machine learning.
+
+# 4 Abbreviations and acronyms

+# 5 Conventions
+
+In this Recommendation:
+
+- The keywords "is required to" indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed.
+- The keywords "is recommended" indicate a requirement which is recommended but which is not absolutely required. Thus, this requirement need not be present to claim conformance.
+- The keywords "can optionally" indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendor's implementation must provide the option, and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with this Recommendation.
+- The keywords "peer" means a hybrid peer.
+- The keywords "HP2P network" means a hybrid overlay network.
+
+# 6 Feature-based video services
+
+This clause describes the overview of feature-based video services and two types of service modes.
+
+## 6.1 Overview
+
+The feature-based video communication approach does not strive to restore the original video. Rather, it employs AI technologies to regenerate scene images. This allows for generating lifelike images and character animations from features, which can be tailored to specific service models. The shape of the features is closely associated with the target service. For instance, in a video conferencing service,
+
+features would predominantly represent facial details, whereas a service focused on dance videos would emphasize the representation of body rig information.
+
+In addition, the feature can be exchanged over an HP2P network, specified in [ITU-T Q.4100], to support many concurrent users. To support this, it needs to specify new protocols running on top of the overlay management protocol and peer protocol, specified in [ITU-T Q.4102] and [ITU-T Q.4103], respectively. This Recommendation specifies signalling requirements for the feature-based video service. These requirements will be used to specify the protocol specification.
+
+## 6.2 Feature-based video service mode
+
+There are two modes for providing video services with features derived from machine learning: shared neural network mode (SNNM) and key points description mode (KDM). This clause describes the two modes in detail.
+
+### 6.2.1 Shared neural network mode (SNNM)
+
+In SNNM mode, each end point shares the same neural network and shares features derived from the neural network. To use this mode, each participant needs to have a neural network model that includes the shape of the neural network and a pretrained model.
+
+Figure 6-1 shows an overall concept of a shared neural network model in which each end point uses the same neural network architecture and pretrained data. A remote end point creates the image using the feature and reference image that is the base image for the newly created image. In this case, the feature may be the output data of a particular neural network layer.
+
+![Diagram illustrating the Shared Neural Network Mode (SNNM) for facial video communication. It shows two end points (represented by faces) connected by a central horizontal bar. Above the bar, a blue double-headed arrow labeled 'Neural network metadata' is shown. Above this arrow, two light blue boxes indicate the 'Feature-based video session control protocol' and 'Feature-based video transport protocol'.

+### 6.2.2 Key points description mode (KDM)
+
+In KDM mode, sharing the same neural network model is unnecessary. Each end point extracts key points of their input stream, converts them into a unified form, and sends them to other end points. Figure 6-2 shows a concept of a key points model that uses landmarks as a feature. A remote end point receiving the key points data recreates the image using the landmark and reference image that is the base image for the newly created image.

+# 7 Signalling requirements for feature-based video session control protocol
+
+This clause describes the signalling requirements for controlling the feature-based video session, such as creation, modification, joining, leaving, etc. Each clause describes the necessity with simple scenarios for a better understanding and the requirements to support it.
+
+## 7.1 Signalling requirements for supporting session owner
+
+This clause specifies the signalling requirements for the features used by a session owner.
+
+### 7.1.1 FVS session creation
+
+A single hybrid overlay service session operates exclusively on one HP2P network. Furthermore, only one overlay service is present in a given HP2P network. If a service client requires multiple services, it can receive them by participating in a separate HP2P network. The HPEER that creates the service session becomes the owner and possesses full control over the service. The service session owner creates the session using the *HybridOverlayCreation* request message specified in [ITU-T Q.4103] and [ITU-T Q.4103Amd1]. Table 7-1 lists the requirements related to session creation.

+#### 7.1.2.3 Floor control
+
+The service session owner can do floor control on a specific service session. The user who has permission can send its message or data to the service session. It is also possible to designate multiple users to broadcast its data at any time. Table 7-6 lists the requirements related to this floor control. When the transmission rights for a service session are altered, the session owner informs the HOMS of the change and broadcasts a notification message to the HP2P network to notify other HPEERs that the transmission rights for the service session have been changed.
+
+**Table 7-6 – Requirements related to floor control**

+| ISC-031 | It is required that HOMS and HPEER support the control of transmission permission by the service session owner.<br>NOTE – The service session owner registers transmission permission to the HOMS. Other peers obtain this information from the HOMS when joining the session. |
+
+#### 7.1.2.4 Modifications on session attributes
+
+The service session owner has modification capabilities on the attributes of the specific service session.
+
+When the attributes of a service session are modified, the session owner notifies HOMS about the changes and broadcasts a notification message to the HP2P network, informing other HPEERs that the service session's attributes have been updated.
+
+Table 7-7 lists the requirements related to the session attributes.
+
+**Table 7-7 – Requirements related to session attributes**

+
+### 7.1.3 FVS session termination
+
+The owner can explicitly terminate the service session, or it may end due to a timeout. When the service session is terminated, the service session owner notifies the HOMS that the session has ended and broadcasts a notification message to the HP2P network to inform other HPEERs that the service has been completed. HPEERs that receive this message propagate it to others while discontinuing any ongoing tree recovery process and terminating any secured primary and candidate paths. The service session owner terminates the session using the *HybridOverlayRemoval* request message specified in [ITU-T Q.4103] and [ITU-T Q.4103Amd1]. Table 7-8 lists the requirements related to the session termination by the owner or the HOMS.
+
+**Table 7-8 – Requirements related to session termination**
+
+| Req.ID  | Requirements                                                                                                                                                       |

+| STR-002 | It is required that when the validity period of a service session has expired, the HOMS also deletes any overlay information associated with that service session. |
+
+## 7.2 Signalling requirements for supporting session users
+
+This clause describes the signalling requirements for the functionalities to be used by a session user.
+
+### 7.2.1 FVS session query
+
+The HOMS provides service information connected to the HP2P network and information on the HP2P network. For the query of the service session, it uses the *HybridOverlayQuery* request message specified in [ITU-T Q.4103] and [ITU-T Q.4103Amd1]. In response to this *HybridOverlayQuery* request message, the HOMS transmits service information and information about the HP2P network. Table 7-9 lists the requirements for the session query. Any user can query the service and session information of ongoing sessions.
+
+**Table 7-9 – Requirements related to session query**
+
+| Req.ID  | Requirements                                                                                                                                                                                                                         |
+|---------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| USQ-001 | It is required for the HOMS to support the query of the feature-based video session in progress by use of the following keywords: <ul style="list-style-type: none"> <li>– title;</li> <li>– description;</li> <li>– etc.</li> </ul> |
+
+### 7.2.2 FVS session join
+
+Not only service users but also the session owner who created the service session is required to participate in the HP2P network. The HOMS determines whether the HPEER sending this message is the owner and sends a different response message. Like general HPEERs, the owner HPEER can freely join or leave the service session. When rejoining, it should be able to obtain all information about the current status of the HP2P network, as well as the status of the service. The service session user joins a specific session using the *HybridOverlayJoin* request message specified in [ITU-T Q.4103] and [ITU-T Q.4103Amd1]. Table 7-10 lists the requirements related to the service session joining by a peer.
+
+**Table 7-10 – Requirements related to service session joining**
+
+| Req.ID  | Requirements                                                                                                                                                                                                                                                                                                                                                                                                                                  |

+
+Since data from various channels transmitted by HPEERs participating in the same hybrid overlay service session are transmitted through HPEERs participating in the HP2P network, ensuring security and integrity in the transmission process is necessary. Table 7-11 lists the requirements for securing integrity on service session joining.
+
+**Table 7-11 – Requirements related to secure integrity on service session joining**

+
+### 7.2.4 FVS session leave
+
+HPEERs in the HP2P network may leave the service session through explicit or implicit procedures. Even if all HPEERs depart, the HP2P network remains valid for a specified period. The service session users leave the session using the *HybridOverlayLeave* request message specified in [ITU-T Q.4103] and [ITU-T Q.4103Amd1]. Table 7-12 lists the signalling requirements for the session leave procedures.

+
+### 7.2.5 FVS session user query
+
+The HPEER participating in a service broadcasts its information by establishing a primary path with existing HPEERs participating in the HP2P network and receives data from other HPEERs from the existing HPEER. Therefore, it is possible to obtain information necessary for the service without interactions with the HOMS. However, when information on a specific service user is unavailable, a user can obtain it from the HOMS. Table 7-13 lists the requirements related to the session user query.

+# 8 Signalling requirements for feature-based video transport protocol
+
+This clause describes the requirements related to the feature-based video transport protocol for exchanging control messages and data messages among HPEERs in an HP2P network corresponding to a feature-based video service. By use of the feature-based video transport protocol, HPEERs can send and receive a unit of container, which includes the following:
+
+- control information;
+- feature;
+- reference image.
+
+The feature-based video transport protocol uses *BROADCAST\_DATA*, specified in [ITU-T Q.4102], and the payload format specified in [ITU-T Q.4102Amd1] on exchanging control information,
+
+reference image and features. The video application uses the reference image and features for reconstructing the video using artificial intelligence, such as generative AI.
+
+## 8.1 Requirements for transporting control information
+
+This clause describes the requirements relevant to transmission control among HPEERs in an HP2P network. The transmission control includes permission adjustment, negotiation between peers, etc.
+
+A peer that has newly joined an HP2P network can get the service information for participating in a service by communicating with the HOMS and the HPEERs already participating. The HPEERs provide the service information generated or changed dynamically. Table 8-1 lists the requirements for handling the service information.

+| CTRL-102 | It is required for a new peer to broadcast a message, including its identifier, user name, public key, reference image, etc., used to receive data and generate the peer's video.       |
+| CTRL-103 | It is required for a peer establishing a primary path with a new peer to send every reference image of each source, peer list, public key, etc., used for feature-based video services. |
+| CTRL-104 | It is recommended that peer uses PGP for signing the control information to be sent to guarantee the integrity of the control information.                                              |
+
+The HPEER with data transmission permission can be a source, and the service session owner controls the permission. The owner of the service session has control over it, and participating peers adhere to this control. The session owner can authorize the peers to send information during the session. Table 8-2 lists the requirements related to the transmission of permission.

+| CTRL-205      | It is required for the service session owner to include a list of service session permission holders and a list of permit holders for a specific channel in the message announcing the permission change.       |
+| CTRL-206      | It is required for the transmission control information to include a list of users consisting of peer-ids that hold transmission control.                                                                       |
+| CTRL-207      | It is required that the message regarding transmission control includes a signature, using the service session owner's private key, on the hash value of the header to prevent any modification of the message. |
+
+When the service session owner explicitly terminates its service session, it informs the peers participating in the HP2P network and removes the registered service session from the HOMS. Table 8-3 lists the requirements related to service session termination.

+
+The service session owner needs to notify all peers participating in the HP2P network when changing the service session information. Table 8-5 lists the requirements related to notifications on the change of the service session information.

+| CTRL-321 | It is required that the session owner broadcasts a relevant control information message to the HP2P network immediately upon changing the information of the service session.                                                                                                                                                             |
+| CTRL-322 | It is required that the message notifying the change of information in a service session includes only non-impactful information on the peers' behaviour, such as title, description, and start and end time. Additionally, the header and extension header of the message should be signed with the service session owner's private key. |
+
+A peer in a service session needs to check the status of other participants to maintain the HP2P network and to provide the latest list of participants to the user corresponding to the peer. When a peer leaves the HP2P network without following the normal leave procedure, the peers with a primary relationship with the peer conduct the connection recovery as specified in [ITU-T Q.4101]. However, the HOMS cannot recognize the leave of the peer before the expiration of the information of the peer or receiving a report from other peers that have recovered a primary relationship. After recognition of the leave of a specific peer, the HOMS gives a list of peers except for the left peer upon the request from a newly-joined peer. Table 8-6 lists the requirements related to service session maintenance for keeping up-to-date information on the HP2P network.
+
+**Table 8-6 – Requirements related to service session maintenance**
+
+| Req.ID   | Requirements                                                                                                                                                                                                                                            |

+| CTRL-331 | It is recommended that a peer is capable of sending a SCAN_TREE message periodically or on a specific event to get the list of peers currently participating in a service session and to provide the latest list to the user corresponding to the peer. |
+| CTRL-332 | It is required for a peer to broadcast its leave when it leaves an HP2P network.                                                                                                                                                                        |
+| CTRL-333 | It can optionally skip the broadcast peer's leave when a service session owner excludes it.                                                                                                                                                             |
+| CTRL-334 | It is required that the message notifying the leave should include the user's ID and a signature using the user's private key to sign the hash value of the header.                                                                                     |
+| CTRL-335 | It is recommended that a peer leaves gracefully by notifying its leave to decrease any possible instability in providing a service and unnecessary exchange of control messages.                                                                        |
+
+It is necessary to provide the service session owner with the ability to remove a specific user from the session. Given the nature of the HP2P network, all peers are expected to relay not only their own data but also that of other peers. However, it is essential to establish procedures for removing peers that are negligent or engaging in malicious behaviour. Table 8-7 lists the requirements related to user expulsion.
+
+**Table 8-7 – Requirements related to user expulsion**

+| CTRL-343      | It is required to provide a way for the message to be delivered to all peers, despite any interference from malicious peers.                                                                                                                             |
+| CTRL-344      | It is required that the receiving peer of this message should terminate its connection with the excluded peer if they are connected via a primary path.                                                                                                  |
+| CTRL-345      | It is required for peers to maintain an exclusion list to avoid re-establishing a primary path relationship with peers on the list within the same HP2P network.                                                                                         |
+| CTRL-346      | It is required that a service session owner sends an encrypted message to the peers with a primary relationship with the peer to be evicted by the service session owner to command the peers to start the recovery process specified in [ITU-T Q.4101]. |
+
+## 8.2 Requirements for transporting reference image
+
+In providing a feature-based video service, the receiver client recreates an image that reflects the user's intention by combining the received reference image and feature. This clause describes the requirements for transmitting features. Table 8-8 lists the requirements related to sharing the reference image of a peer.
+
+**Table 8-8 – Requirements related to sharing reference image**
+
+| <b>Req.ID</b> | <b>Requirements</b>                                                                                                                     |
+|---------------|-----------------------------------------------------------------------------------------------------------------------------------------|
+| TVF-101       | It is required that a peer broadcasts its reference image immediately after establishing a primary path.                                |
+| TVF-102       | It can optionally be arranged for a peer to transmit their reference images on the primary path that the recovery procedure has set up. |
+| TVF-103       | It is required to propagate the reference image to the HP2P network whenever it is updated.                                             |
+
+## 8.3 Requirements for transporting video features
+
+The video feature takes different forms depending on the service mode used. In other words, in the SNNM, it will be a feature vector generated based on the structure of the neural network used by participating peers; while in the KDM, it will be data aligned with the notational syntax describing the key points. Table 8-9 lists the requirements related to the video feature.
+
+**Table 8-9 – Requirements related to the video feature**
+
+| <b>Req.ID</b> | <b>Requirements</b>                                                                                                                                                                                                                                                                                                                                                          |

+1.1 For the purposes of this Recommendation, an international exchange is a collection of equipment regarded as an entity by the Administration concerned. In the case of an international transit centre, it extends from the end of the incoming international line to the beginning of the outgoing international line (e.g. between such points as A and D in Figure 1/Q.45 or any other suitable pair of points).
+
+In the absence of an international agreement on the choice of the points delimiting an international exchange, it has proved impossible to draw up model specifications showing the limits to be observed for quantities measured between these points. The CCITT recommendations given hereafter have been issued regardless of the actual arrangement.
+
+Automatic international exchanges should be provided with circuit test access points (see Recommendation M.700 [1]) complying with the Recommendation cited in [2]. This Recommendation will ensure that circuit line-up and maintenance testing procedures are referred to points at or near the switchblock (Points B and C of Figure 1/Q.45).

+
+<sup>1)</sup> The transmission characteristics of a digital international exchange are specified in Recommendation Q.507.
+
+1.2 The essential transmission requirements for an international exchange are:
+
+- a) The *transmission loss* through the centre should be substantially constant with time and independent of the routing through the centre.
+- b) *Crosstalk and noise* should be negligible.
+- c) The *distortions* introduced should be small. These include attenuation distortion, non-linear distortion and intermodulation products.
+- d) *Impedance and balance with respect to earth* at the points in the international exchange to which the lines are connected should be closely controlled.
+
+1.3 The following recommendations apply to new automatic 4-wire international exchanges of the electro-mechanical type. It is desirable that they should apply to new national 4-wire exchanges. They may also be applicable to electronic exchanges having metallic contact crosspoints.
+
+These recommendations are intended to be used only as type tests, acceptance tests, or for special investigations. They do not constitute a complete specification. Generally the recommended tests should be conducted on a sampling basis.
+
+## 2 Definitions
+
+2.1 *Definition of a “connection through an exchange”*
+
+Crosstalk and noise conditions for a 4-wire international exchange are defined by reference to a “connection through this exchange”. By **connection through an exchange** is to be understood the pair of wires corresponding to one direction of transmission (GO direction or RETURN direction) and connecting the input point of one circuit incoming in the exchange and the output point of a different circuit outgoing from the exchange (these input or output points are often taken at the test-jack frame).
+
+A connection through the international exchange is shown by a heavy line in Figure 1/Q.45.
+
+2.2 *Definition of switching equipment input and output points*
+
+Although the virtual switching points, which are points at which the two circuits are considered to be directly connected, are theoretical points, in practice it will always be possible to choose a point considered as the *switching equipment input* for the receive channel of a circuit and a point considered as the *switching equipment output* for the transmit channel of a circuit.
+
+The exact position of each of these points depends on national practice and it is unnecessary for the CCITT to define it. Only the national authority responsible for each international transit centre can fix the position of these points in each case.
+
+The switching equipment input point associated with a receive channel may be such that the nominal relative level is different from  $-4.0$  dBr. Let this nominal relative level be  $R^2$ ).
+
+The switching equipment output point associated with a transmit channel may be such that the nominal relative level is different from  $-3.5$  dBr. Let this nominal relative level be  $S^2$ ).
+
+Consider a circuit between the switching centre concerned and the adjacent centre. Let  $T$  be the nominal transmission loss between virtual switching points at the two ends of the channel of this circuit, which is the receive channel in the centre concerned.
+
+When a transit connection is established through a centre by connecting the receive and transmit channels of one circuit to the transmit and receive channels respectively of another circuit, in order to ensure that the virtual switching points have been connected together with additional loss or gain, the *nominal* value of the attenuation (loss) to be introduced between the switching equipment input and the switching equipment output is  $R - S + T$ .
+
+2.3 *Definition of the net switching loss*
+
+Let the actual value of the attenuation introduced between the switching equipment input and output points be  $A$ . The net switching loss is defined to be equal to the difference between this *actual* value and the *nominal* value of the attenuation. Thus:
+
+$$\begin{aligned}\text{Net switching loss} &= \text{actual loss} - \text{nominal loss} \\ &= A - (R - S + T).\end{aligned}$$
+
+---
+
+2) If the value of  $R$  is chosen to be higher than the value of  $S$ , the level difference can be used to offset any inherent transmission loss in the switching equipment and the requirements of the transmission plan can be met without any need to install supplementary audio-frequency amplifiers.
+
+## 3 Recommendations concerning transmission loss
+
+### 3.1 Net switching loss
+
+Ideally, the net switching loss of an international exchange would always be zero. That is, the *actual* loss (*A*) should equal the *nominal* loss ( $R - S + T$ ).
+
+*Example* – The relationship between the actual switching points and the virtual switching points in a practical international exchange is illustrated in Figure 2/Q.45. In this arrangement:
+
+$$R = +7 \text{ dBr},$$
+
+$$S = -16 \text{ dBr},$$
+
+and *T* is assumed to be 0.5 dB
+
+so that the nominal transmission loss needed between the +7 and -16 dBr points is:
+
+$$(+7) - (-16) + (0.5) = 23.5 \text{ dB}.$$
+
+In practice, different connections established by the switching equipment will introduce different values of net switching loss so that a distribution of net switching losses will arise. The mean value of this distribution should be very close to zero but does not need to be specified.
+
+### 3.2 Loss dispersion
+
+According to the Recommendation cited in [2], circuit test-access points are located at or near the switchblock (points B and C of Figure 1/Q.45). Moreover, the dispersion of loss is mainly due to the diversity of paths in the switchblock. It is therefore only necessary to consider the dispersion of loss between the points B and C.
+
+The standard deviation of loss measured at 800 Hz of all possible paths between points B and C should be as small as possible. For purposes of calculation a value of 0.2 dB may be assumed.
+
+In order to conform to this value, it is considered sufficient that, for purposes of design and acceptance testing, the difference between the losses at 800 Hz of the shortest and longest paths from point B to point C in no case exceeds 0.8 dB. For a practical assessment of the average value of net switching loss, the contribution from the switchblock can be taken as the mean of the maximum and minimum values of loss between points B and C.
+
+These values apply for connections routed directly, and once only, through the switchblock. Due to the fact that the switchblock contains only switches and associated cabling, the actual loss between points B and C in any case can only have positive values.
+
+If special re-entrant trunking arrangements are used, requiring the connection to pass through the switchblock twice (this may be a convenient way to extend the availability of the switching network or to introduce additional equipment, e.g. echo suppressors), the maximum loss and loss dispersion will be increased. In view of this, the re-entrant technique should not be used to such an extent as to increase significantly the mean net switching loss of the exchange.
+
+### 3.3 Nonlinear distortion
+
+The transmission loss measured on any “connection through the international exchange” should not vary by more than 0.2 dB when the level of the test-tone is varied from -40 dBm0 to +3.5 dBm0.
+
+### 3.4 Loss-frequency distortion referred to 800 Hz
+
+The difference between the transmission loss measured on any “connection through the international exchange” over the frequency bands indicated below and that measured at 800 Hz<sup>3)</sup>, should lie within the following limits:
+
+$$\begin{aligned} 300-400 \text{ Hz: } & -0.2 \text{ dB to } +0.5 \text{ dB}, \\ 400-2400 \text{ Hz: } & -0.2 \text{ dB to } +0.3 \text{ dB}, \\ 2400-3400 \text{ Hz: } & -0.2 \text{ dB to } +0.5 \text{ dB}. \end{aligned}$$
+
+<sup>3)</sup> 1000 Hz is an acceptable alternative frequency.

+
+## 4 Crosstalk recommendations
+
+4.1 Crosstalk should be measured in exchanges at a frequency of 1100 Hz in accordance with Recommendation G.134 [3].
+
+4.2 *Crosstalk between connections established (between points A and D)*
+
+In an international 4-wire exchange the signal to crosstalk ratio measured at points A and D between any two “connections through the international exchange” (see definition in § 2.1 above) should be 70 dB or better.
+
+This limit of 70 dB should normally apply to the most unfavourable case, in which two “connections” have parallel paths throughout the international exchange. It should be noted that this does not occur in practice, because normal cabling layout is such that when, at one switching stage, two “connections” use adjacent switches, in the following stage the two “connections” generally use switches which are not adjacent.
+
+4.3 *GO to RETURN crosstalk of the same path (between points A and D)*
+
+The signal-to-crosstalk ratio between the two “connections” which constitute the GO and RETURN channels of a 4-wire path established through the international exchange should be 60 dB or better.
+
+## 5 Noise recommendations
+
+For a 4-wire international exchange, noise measurements should be performed on a “connection through the exchange” during the busy-hour. (The *busy-hour* is defined in [4].) Each channel of the connection should be terminated at points A and D of Figure 1/Q.45, in 600 ohms. The noise should be measured at the downstream end of each channel and should be referred to a point zero relative level in that channel. Thus, in Figure 1/Q.45 the noise in the upper channel is measured at D and the noise in the lower channel is measured at A.
+
+### 5.1 Mean noise power during the busy-hour
+
+The mean of the noise over a long period during the busy-hour should not exceed the following values:
+
+- Psophometrically weighted noise:  $-67 \text{ dBm0p}$  ( $200 \text{ pW0p}$ ),
+- Unweighted noise:  $-40 \text{ dBm0}$  ( $100\,000 \text{ pW0}$ ) measured with a device with a uniform response curve throughout the band  $30\text{--}20\,000 \text{ Hz}$ .
+
+*Note* – A sufficient variety of connections should be chosen to ensure that the measurements are representative of the various possible routes through the exchange.
+
+### 5.2 Impulsive noise during the busy-hour
+
+Noise counts should not exceed 5 counts in 5 minutes at a threshold level of  $-35 \text{ dBm0}$  (see Annex A to this Recommendation for measurement procedure).
+
+*Note* – Figure 3/Q.45 shows the maximum number of impulsive noise counts acceptable on a 5-minute period.
+
+![Figure 3/Q.45: Impulsive noise requirements for 4-wire exchanges. A log-log graph showing the average number of impulsive noise counts per 5 minutes (y-axis, 0.1 to 100) versus threshold level in dBm0 (x-axis, -50 to 0).](797231cfee084ca299de599340240401_img.jpg)
+
+The graph plots the average number of impulse noise counts per 5 minutes (logarithmic scale from 0.1 to 100) against the threshold level in dBm0 (linear scale from -50 to 0). It identifies specific requirement zones:
+
+- Recommendation Q.45:** Represented by a solid black rectangular area. The limit is 5 counts at a threshold level of  $-35 \text{ dBm0}$ .
+- Recommendation V.53, § 4 [5]:** Represented by a hatched rectangular area. The limit is 8 counts at a threshold level of  $-21 \text{ dBm0}$ .
+- For special quality leased circuits:** A further hatched area is shown to the right of the V.53 region, extending towards higher threshold levels.
+
+The graph is identified by the code CCITT-48462.

+
+## 6 Other transmission recommendations
+
+### 6.1 *Intermodulation products (measured at A and D)*
+
+The intermodulation products to be taken into account for end-to-end multifrequency signalling and for data transmission are those of the third order, of type  $(2f_1 - f_2)$  and  $(2f_2 - f_1)$  where  $f_1$  and  $f_2$  are two signalling frequencies.
+
+For a measurement of the intermodulation products, the two frequencies to be used are 900 Hz and 1020 Hz (see [6]). With each frequency  $f_1$  and  $f_2$  at a level of  $-6$  dBm0, the difference between the level of either frequency  $f_1$  or  $f_2$  and the level of either of the intermodulation products at  $(2f_1 - f_2)$  or  $(2f_2 - f_1)$  should be at least 40 dB.
+
+### 6.2 *Group delay distortion (measured between A and D)*
+
+The group delay distortion measured on any “connection through the international exchange” over the band 600-3000 Hz should not exceed 100 microseconds.
+
+### 6.3 *Return loss (measured at A and D, from A towards D and from D towards A)*
+
+At any frequency from 300-600 Hz the return loss measured against 600 ohms should be not less than 15 dB. The corresponding value from 600-3400 Hz should be not less than 20 dB.
+
+### 6.4 *Impedance unbalance to earth*
+
+6.4.1 The impedance unbalance to earth measured, at points A and D, should not be worse than:
+
+300- 600 Hz: 40 dB;
+
+600-3400 Hz: 46 dB.
+
+*Note* – Some Administrations guided by their knowledge of local conditions may feel a need to specify a figure for a lower frequency, for instance, 50 Hz.
+
+6.4.2 The degree of unbalance to earth is defined as the ratio  $u/U$  measured as shown in a) and b) of Figure 4/Q.45 and is expressed in decibels as the reciprocal of this ratio in transmission units.
+
+The diagrams of Figure 4/Q.45 used for measurement of unbalance differ only in respect of the presence or absence of an earth at the mid-point of the termination. Unbalance measurements according to a) and b) of Figure 4/Q.45 can give quite different results according to the nature of the unbalance.
+
+6.4.3 The CCITT has recommended in 1968 that the set of limit values of § 6.4.1 above should be met for unbalance to earth measured with *both* measuring diagrams according to Figure 4/Q.45.
+
+## 7 Use of cables specified by the IEC
+
+The cables for telephone exchanges in accordance with the IEC (International Electrotechnical Commission) publication cited in [7] will meet the electrical characteristics required by the CCITT (especially as regards crosstalk) for ordinary exchanges, but this may no longer hold good for larger exchanges with considerable lengths of cable.
+
+In accordance with Recommendation G.231 [8], it will be for the Administrations or the contractors to check whether standard cables will be satisfactory in equipping an exchange which requires telephone cables of exceptional length.
+

+## ANNEX A
+
+(to Recommendation Q.45, § 5.2)
+
+### Procedure for impulsive noise measurements
+
+A.1 A test circuit should be formed by setting up a connection across the switching unit and terminating the connection on one side of the exchange by the appropriate closing impedance and on the other by the impulse measuring device in parallel to the closing impedance. Those terminating points should be points A and D in the diagram of Figure 1/Q.45 (or equivalent points) to include the switching equipment of the exchange. Where it is the desire of an Administration, measurements may be made at points X and Y if precautions are taken to ensure that the results apply only to the automatic switching equipment, signalling equipment, echo suppressors, relay sets, pads and cabling of the exchange.
+
+A.2 The measurements should be made using the device specified in Recommendation O.71 [9]. The 600-3000 Hz filter network described in [10] should be in the circuit.
+
+A.3 The measurements should be made at times when the probability of noise occurring is at its highest, that is normally during the busy-hour.
+
+A.4 The time of observation for each test should be five minutes.
+
+*Note* – The number of different test circuits set up across the exchange for measuring should take into account the size and complexity of the switching unit and should be a number sufficient to represent the various possible types of calls and routes through the exchange.
+
+See also the document cited in [11].

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, and information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <http://www.itu.int/ITU-T/ipr/>.

+# 5 Conventions
+
+In this Recommendation:
+
+The keywords "is required to" indicate a requirement which must be strictly followed and from which no deviation is permitted, if conformance to this Recommendation is to be claimed.
+
+The keywords "can optionally" indicate an optional requirement which is permissible, without implying any sense of being recommended. This term is not intended to imply that the vendor's implementation must provide the option, and the feature can be optionally enabled by the network operator/service provider. Rather, it means the vendor may optionally provide the feature and still claim conformance with this Recommendation.
+
+# 6 Overview
+
+## 6.1 General

+The IMT-2020 network provides a variety of services over network and computing infrastructure, including enhanced mobile broadband (eMBB) services, services based on large-scale machine type communication (MTC) and services based on ultra-reliable low-delay communication (URLLC). It can support large-scale network access, flexible connectivity and topology, fixed/mobile convergence, and user plane optimization. Meanwhile, the IMT-2020 network has many features that can help improve the efficiency and flexibility of network services, such as distributed architecture based on software-based network functions, software-defined networking, access network agnostic common core network, network slicing, intelligent resource management, etc.
+
+The IMT-2020 networks include core network, access network, user equipment, application function and data networks. The functional parts of the IMT-2020 network, except for the application function, are divided into control plane and data plane. As shown in Figure 6-1, considering the framework of the IMT-2020 network defined in [ITU-T Y.3102], the IMT-2020 network provides different network services by using different access networks, core networks and functional entities.

+
+Traditional connectivity services struggle to meet the demands of enterprise users for high-speed access, secure interconnection, service isolation and flexible networking. Considering the different access networks with varying connection requirements, ensuring service level agreement (SLA) service quality has become a high priority. Nowadays, there are numerous applications that require terminal mobility, such as mobile office and media broadcast scenarios. In these scenarios, it is essential to support data transmission quality via not only IMT-2020 AN but also other ANs (such as IMT-2000 or IMT Advanced). Therefore, flexible switching between different ANs is necessary to guarantee high-quality and high-reliability service transmission when switching between different ANs. Currently, signalling quality is enhanced by using quality of service (QoS) and slicing technologies to ensure large bandwidth, strong isolation and high reliability of services.
+
+The IMT-2020 network is supposed to enhance network connection quality to support terminal mobility and ensure reliable transmission. It supports non-IMT-2020 network access modes and facilitates active-passive disaster recovery switchover. In cases of switching between multiple access
+
+modes and recovery switchover from network faults, seamless switchover is implemented to ensure service transmission quality.
+
+## **6.2 Scenario requirements**
+
+### **6.2.1 Scenario requirements for enhanced mobility**
+
+In mobile office and other scenarios, it is necessary to realize flexible switching between various network access modes while ensuring the differentiated service quality of the network.
+
+To support the enhancement of mobility capability in IMT-2020 networks and future networks, policies can be implemented through the network access control function (NACF). This enables flexible switching between IMT-2020 AN and other ANs (such as IMT-2000 or IMT Advanced). Enhancing the internal signalling interactions between NACF and the session management function (SMF) is required to effectively report pertinent information. By improving the interactions among the aforementioned function modules, it is possible to enhance QoS and optimize other parameters when interfacing between different ANs, such as IMT-2000 or IMT Advanced, and the IMT-2020 network. This will result in a high-quality and flexible handoff of network access, ensuring seamless transitions for users across various ANs.
+
+### **6.2.2 Scenario requirements for enhanced reliability**
+
+For end-to-end network connection, it is usually necessary to support active-passive disaster recovery to ensure the high reliability of service quality. The service flow on the data plane extends from the base station to the IMT-2020 user plane function (UPF) through the fixed network segment. In the event of a fault of the active UPF, ensuring the uninterrupted forwarding of service flows is imperative to achieve high end-to-end network reliability in the active/standby UPF disaster recovery scenario, which involves session switchover.

+
+## **7.1 General**
+
+Figure 7-1 shows the core network functions of the IMT-2020 network and highlights enhancements of the functionalities of SMF. These enhancements include improving interaction between SMF and QoS mapping function, enhancing mobility management communication between IMT-2020 network and other ANs (such as IMT-2000 or IMT Advanced), and improving reliability communication between SMF and UPF. As the core function of session management within the IMT-2020 network, the policy control function (PCF) is responsible for interacting with the access and mobility policy enforcement in NACF and the mobility management function (MMF), and provides the associated policies. The SMF is responsible for tunnel maintenance, IP address allocation and management, policy enforcement, QoS control, roaming, etc. It selects and manages the UPF, configures UPF traffic and direction, and forwards the traffic to the appropriate destination network.

+
+**Figure 7-1 – Signalling architecture for enhanced quality in IMT-2020 networks and beyond**
+
+When the user equipment (UE) accesses the IMT-2020 network, it initially connects to the first core network. If the UE moves into the coverage area of other networks access, it connects to the second core network. NACF of the first core network and the mobility management function (MMF) of the second core network interact with each other based on the fallback information of the target terminal. This fallback information includes session information of the target terminal. The SMF of the first core network receives the fallback information sent by the MMF. To enhance the mobility and reliability of the IMT-2020 network, it is required to improve communication capabilities of SMF and add the QoS mapping function. This addition is crucial to meet the flexible migration requirements of the IMT-2020 network and other network services. The SMF is required to obtain user information of the target terminal based on the session information and query the target QoS mapping strategy from the pre-stored QoS mapping strategy based on the user information after the target terminal switches to the target network. Subsequently, the target QoS mapping strategy is pushed down to the target terminal. To prevent service flow forwarding anomalies caused by UPF failures, the main and standby UPF disaster recovery mechanism is adopted. The communication processes and session detection of SMF and UPF are enhanced to achieve the synchronous switching of sessions and routes, enabling service-level main/standby UPF disaster recovery.
+
+## 7.2 Signalling requirements for enhanced mobility
+
+### 7.2.1 Signalling requirements for enhanced quality of connection service assurance
+
+To achieve enhanced quality of connection service assurance of the IMT-2020 network and realize flexible switching between various access modes and guarantee its network service quality, the following capabilities are required:
+
+- **Quality of service assurance:** The communication mechanism through signalling of the RP-sq reference points is required to support service-level quality of service assurance and realize QoS mapping between different network access modes. The pre-stored QoS mapping policies are categorized based on service types. These policies entail the correspondence between various QoS parameters and then the terminal performs network switching. The QoS parameters primarily encompass service quality identification, address resolution protocol (ARP), preemption attribute, preempted attribute, and upstream and downstream bit rate information.
+
+### 7.2.2 Signalling requirements for enhanced mobility management
+
+To enhance the mobility guarantee of the IMT-2020 network and realize flexible switching between various access modes, the following capabilities are required:
+
+- Mobility management: The RP-ns reference point and the RP-nm reference point are required to support seamless migration between IMT-2020 AN and other ANs.
+- Session state maintenance: The communication mechanism through signalling of the RP-sm reference point is required to support the ability to maintain the state of the session.
+
+### 7.2.3 Signalling requirements for the high reliability of connection service assurance
+
+To enhance the high reliability of connection service assurance and support the active/standby user disaster recovery scenario, the following capabilities of the first interface (namely RP-su) of the main UPF and the second interface (namely RP-ud) of the user plane function are required:
+
+- **Support user plane redundancy transmission based on dual connections:** The RP-su reference point is required to support the session communication between the main UPF and SMF, which provides redundant user plane resources for a given protocol data unit (PDU) session through dual connections. It also supports Ethernet PDU session anchor recovery.
+- **Support redundant data network transmission:** RP-ud is required to implement communication between the main UPF and the gateway device. The RP-ud reference point and the RP-su reference point are required to be bound to the PDU session, enabling the monitoring of the operational status of the RP-su and RP-ud.
+
+NOTE – This monitoring of UPF involves adding a session exception reporting process in the signalling flow to facilitate session monitoring and dynamic switching of service flows.

+## Recommendation ITU-T Q.5021
+
+## Protocol for managing capability exposure APIs in IMT-2020 networks
+
+# Summary
+
+Recommendation ITU-T Q.5021 describes the protocol for managing capability exposure application programming interfaces (APIs) in International Mobile Telecommunications (IMT)-2020 networks. It includes signalling architecture, API management functions, signalling flows and their message format, and definition for management APIs. It also describes gap analysis and use cases for API management.
+
+This protocol can be used by network operators and third parties to manage capability exposure APIs.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at <http://www.itu.int/ITU-T/ipr/>.

+
+# 6 Signalling architecture for API management
+
+To avoid duplication and inconsistency of capability exposure APIs to various third-party application functions (AFs), development of a common capability exposure API framework was needed that includes common aspects (e.g., API registration, API discovery, API authorization) that were applicable to any functional APIs when used by a third-party.
+
+Figure 6-1 shows the architecture model for the capability exposure API management system and the relationship with the capability exposure function (CEF), the third-party application and the IMT-2020 core network functions.
+
+The capability exposure function provides functionalities to expose its capabilities as a service externally and capability exposure APIs to the third-party. For high-level descriptions of the functionalities and APIs refer to [b-ITU-T Y.IMT2020-CEF].
+
+The API management function is mainly responsible for management of the capability exposure API, including API registration, API deregistration, API discovery, API authorization, API authentication, API suspension, API recovery, API charging and monitoring and API topology hiding.
+
+The IF1 reference point is the southbound interface, which exists between the CEF and the IMT-2020 core network functions. It supports:
+
+- subscription and unsubscription of network capabilities;
+- query and reporting of network capabilities;
+
+The IF2 reference point is the northbound interface, which exists between the CEF and the third-party application. It supports exposure of network capabilities to the third-party application through the invocation of capability exposure APIs.
+
+The IF3 reference point is the northbound interface, which exists between the API management function and the third-party application. It supports discovery of capability exposure API.
+
+The IF4 reference point exists between the CEF and the API management function. It supports:
+
+- registration and deregistration of capability exposure API;
+- invocation event report of capability exposure API;
+- suspension and recovery of capability exposure API.

+
+# 7 Functions for API management
+
+## 7.1 API registration
+
+For the API management function to properly maintain the information of available CEF instances and their supported capability exposure APIs, each CEF instance informs the API management function of the list of capability exposure APIs that it supports.
+
+The CEF instance may make this information available to API management function when the CEF instance becomes operative for the first time (registration operation) or upon individual CEF service instance activation/de-activation within the CEF instance (update operation), e.g., triggered after a scaling operation. The CEF instance may also update or delete the CEF service related parameters. Alternatively, another authorised entity (such as an operations, administration, and management (OA&M) function) may inform the API management function on behalf of an CEF instance triggered by an CEF service instance lifecycle event (register or de-registration operation depending on instance instantiation, termination, activation, or de-activation). Registration with the API management function includes capacity and configuration information at time of instantiation.
+
+## 7.2 API discovery
+
+The API discovery enables the third-party applications to discover a set of CEF instance(s) with specific capability exposure APIs.
+
+Unless the expected CEF instance and capability exposure APIs information are locally configured on requester third-party applications, the API discovery is implemented via the API management function.
+
+In order to access to the target CEF instance and get information of target capability exposure API, the requester third-party application initiates the API discovery procedures by providing the specific information of the third-party and APIs. The detailed service parameter(s) used for specific API discovery are defined in clause 9.
+
+The API management function may provide the IP address or the node name of CEF instance(s) to the requester third-party application. Based on that information, the requester third-party application can select one specific CEF instance that is able to provide a particular capability exposure API.
+
+## **7.3 API authorization**
+
+The API authorization is required to ensure the third-party application is authorized to access the capability exposure API provided by CEF, according to the API authorization information. The API authorization information is configured as one of the components in the CEF profile and provide to the API management function during the API registration procedures. It includes the type and other parameters of the third-party application such as the third-party application identity.
+
+The API management function will check whether the third-party application is permitted to discover the requested capability exposure API during the API discovery procedure according to the API authorization information.
+
+## **7.4 API authentication**
+
+The API authentication is required to ensure the mutual authentication between the third-party application and API management function, before the exposure of capability exposure APIs to the third-party application. The authentication method is used to provide integrity protection, replay protection and confidentiality protection via the IF3 reference point.
+
+The API management function will authenticate the third-party application based on the identity and key of the third-party application.
+
+## **7.5 API deregistration**
+
+APIs are required to be deregistered through API management, e.g., the operator may not provide the invocation of the API to third-party applications, the API is about to shutdown or disconnect from the network or API is expired. The API management indicates the deregistration of the API to the CEF. The CEF will delete the API context and inform the third-party application of the API deregistration.
+
+## **7.6 API suspension**
+
+An API is required to be suspended according to the suspension indication from API management, e.g., API management preconfigures the time window of the permitted of the API usage, operator cannot provide the invocation of the API temporarily. The API management indicates the suspension of the API, and the CEF suspends the API from running state and stores the context of the API accordingly. Once the API runs into suspension state, the CEF will notify the suspension state of the API to the third-party applications.
+
+## **7.7 API recovery**
+
+An API can be recovered from suspension state, e.g., operator resume the invocation of the API to the third-party applications, API management preconfigures the time of API resumption. The API management indicates the CEF that the API has been recovered to the running state. Accordingly, the CEF resumes the API based on the context of the API previously stored at the moment of the API suspended. And then the CEF notifies the third-party applications the permitted usage of the API.
+
+## **7.8 API charging and monitoring**
+
+When the third-party application invokes CEF API, the CEF will send this API invocation event to the API management function.
+
+The API management function will monitor the invoking event and charge based on it.
+
+## **7.9 API topology hiding**
+
+The API topology hiding is required to ensure the API management function act as the entry point for service API invocation when the third-party application is not in the IMT-2020 network trust domain.
+
+CEF invokes the topology hiding API before communication with the third party for first time. The API management function will hide the address of CEF and other related network functions, network inside topology and path information from the third-party application which is not in the trust domain of IMT-2020 network.
+
+## 7.10 API location query
+
+Specific kinds of third-party applications need to know the location of user equipment (UE), like map application, navigation application. CEF queries IMT-2020 core network for the location of UE and return it to the third-party.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <http://www.itu.int/ITU-T/ipr/>.

+# 6 Overview
+
+With the increasing requirement for an IMT-2020 network in edge environments from vertical industries, the demand for user plane function (UPF) is diverse and urgent. Service-based UPF is proposed to meet the needs of verticals.
+
+Based on the internal function modularization of UPF, clear and independent services lead to easy deployment and reorganization. In addition, open application programming interface (API) offers 3<sup>rd</sup> party applications to develop functions independently, such as secondary authentication in the industry and autonomous internet protocol (IP) address allocation. The customized function
+
+management service will manage and orchestrate customized functions from 3<sup>rd</sup> party applications in the UPF. Based on the internal and external modularization, UPF is easy to be customized and reorganized.
+
+# 7 Modularized UPF architecture
+
+Figure 7-1 shows the architecture reference model of service based UPF and open API in the IMT-2020 network. It includes the UPF native function services and customized services from 3<sup>rd</sup> party applications. It also shows the relationship between UPF and other core network functions (NF) of IMT-2020 and 3<sup>rd</sup> party applications. UPF interacts with the network function registry function (NFR) by invoking service based interfaces.
+
+Native function / services of UPF includes traffic routing and forwarding, protocol data unit (PDU) session tunnel management, policy control, anchor point, event exposure, security management and other customized functions, like packet inspection and collection of UPF traffic for lawful intercept and interworking functionalities among different network domains, e.g., interworking between IP-based core network and non-IP based access network. These UPF services can be invoked by other network functions to achieve related functionalities, and these UPF services can be created, updated, or removed.
+
+Traffic routing and forwarding: UPF supports
+
+- traffic forwarding, dropping and buffering, including IPv4, IPv6 and Ethernet type;
+- forwarding traffic to the session management function (SMF), radio access network (RAN), data network (DN) and 3<sup>rd</sup> party applications;
+- classifier for traffic based on traffic forwarding rules.
+
+PDU session tunnel management: UPF supports
+
+- encapsulation and decapsulation of the packet for tunnel;
+- enforcement of tunnel establishment and release based on the rules received from SMF.
+
+Policy control: UPF supports
+
+- predefined rules configured by network management;
+- dynamic policies configured for traffic flows by the policy control function (PCF) via SMF, e.g., Quality of service (QoS) enforcement rule, traffic forwarding rule with SMF invoking UPF policy control services;
+- traffic usage report based on traffic volume, usage time and event.
+
+Anchor point: UPF supports
+
+- act as a PDU session anchor point providing access to the DN;
+- multiple session anchors in a single PDU session;
+- construct end marker when RAN handover.
+
+Event exposure: UPF supports
+
+- Expose PDU session related information;
+- Expose UPF load information.
+
+Security management: UPF supports
+
+- Clear user personal information, such as a subscription permanent identifier (SUPI), etc., after the session ends;
+- Access device security monitoring and access address security verification;
+- Interface filtering and security protection.
+
+Customized services are developed independently by 3<sup>rd</sup> party based on an open API offered by UPF, which are managed and orchestrated by a customized service management.

+
+**Figure 8-10 – Session release procedure**
+
+- 1 SMF sends Nupf\_Session\_Release\_Request message to the UPF to release the session between the SMF and the UPF and release the related context in the SMF and the UPF.
+- 2 The UPF deletes any context related to the PDU session. Optionally, the core network tunnel for local area networks can also be released when the release message is received.
+- 3 The UPF sends a Nupf\_Session\_Release\_Response message to the SMF.
+
+## 8.11 Local area network tunnel set-up between UPFs
+
+This procedure will be used to establish an IMT-2020 local area network (LAN) tunnel between UPFs. An IMT-2020 local area can provide a group of users with a local area network through an IMT-2020 network. When users within the group communicate with each other, they can directly exchange data packets within the network. When this group of users is under two different PDU session anchor UPFs which provide IMT-2020 local area network type services, a core network tunnel
+
+for the IMT-2020 local area network needs to be established between them to forward data for the group of users. The detail of the procedure is shown in Figure 8-11.
+
+![Sequence diagram showing the local area network tunnel set-up procedure between SMF, UPF1, and UPF2. The steps are: 1. SMF sends Nupf_LAN_Tunnel_Establish_Request to UPF1; 2.

+
+**Figure 8-11 – Local area network tunnel set-up between UPFs procedure**
+
+- 1 In order to set up a core network tunnel between two UPFs for the IMT-2020 local area network, SMF firstly sends a Nupf\_LAN\_Tunnel\_Establish\_Request message to UPF1. Since the tunnel parameters can be allocated by the UPF, then the parameters will not be included in the Nupf\_LAN\_Tunnel\_Establish\_Request message to UPF1.
+- 2 UPF1 receives the request message and allocates the tunnel parameters and sends them back to the SMF in the response message.
+- 3 Then the SMF sends the Nupf\_LAN\_Tunnel\_Establish\_Request message including the tunnel parameters to UPF2.
+- 4 UPF2 receives the request message and saves the parameters allocated by UPF1, from which the UPF2 knows the destination when forwarding data packets. Then UPF2 allocates the tunnel parameters and sends them back to the SMF in the response message.
+- 5 SMF forwards the tunnel parameters allocated by UPF2 to UPF1.
+
+## 8.12 UPF event exposure
+
+UPF can expose real-time network information to a 3<sup>rd</sup> party via the capability exposure function (CEF), e.g., PDU session information (QoS profile) or end-to-end latency. CEF may establish a session with the UPF based on the UPF ID / FQDN and communicate directly with the UPF to get the corresponding PDU session information in order to achieve low latency information exposure. The procedure is shown in Figure 8-12.

+## Recommendation ITU-T Q.5054
+
+# Consumer-centric framework for combating counterfeit and stolen information and communication technology mobile devices
+
+## Summary
+
+Recommendation ITU-T Q.5054 provides a consumer-centric framework through a unified platform considering possible scenarios and a multipronged approach for combating counterfeit and stolen mobile telecommunication/ICT devices.
+
+This Recommendation builds upon Recommendation ITU-T Q.5050, which offers a reference framework with high-level challenges and requirements that should be considered when deploying solutions to combat the circulation and use of counterfeit information and communication technology (ICT) devices. Furthermore, Recommendation ITU-T Q.5051 presents a 'Framework for combating the use of stolen mobile devices'. It also defines possible communication channels and consumer interfaces with platform, indicative query and response formats including approaches for consumer education and awareness. The Recommendation also covers key features of the platform, key security considerations, implementation scenarios and possible technical challenges related inter alia to vendor agnostic interfaces, mobile equipment bulk verification, dealing with devices with replicated unique identifiers and the reporting and handling of stolen or lost mobile telecommunication/ICT devices and their restoration upon recovery.
+
+With the rapid growth in the reach of the Internet and accelerated adoption and usage of ICT during the COVID-19 pandemic, the circulation and use of counterfeit ICT devices has increased considerably. According to an OECD report published in 2017, at that time already nearly one in five mobile phones shipped internationally was fake or counterfeit. The growing trade in counterfeit IT and communications hardware burdens on consumers, manufacturers and public finances.
+
+A counterfeit ICT device is a product that explicitly infringes the trademarks, copies hardware or software designs, or infringes brand or packaging rights of an original or authentic product and, in general, infringes applicable national and/or international technical standards, regulatory requirements or conformity processes, manufacturing licensing agreements or other applicable policy requirements. Major mobile telecommunication/ICT devices include inter alia smartphones, tablets, IoT devices, wearables, modems, dongles and wireless local area network (WLAN) routers with cellular network connectivity. In addition to counterfeit mobile telecommunication/ICT devices, the use of stolen devices in mobile network also poses a serious security and law and order problem.
+
+The unchecked proliferation of counterfeit and stolen mobile telecommunication/ICT devices in public land mobile networks (PLMNs) poses a serious challenge to regulators, law enforcement agencies (LEA) and end consumers and adversely affects the economy in general. The supply and demand economics of counterfeit and stolen devices complicate attempts to check the local as well as global market scenario for such devices.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, and information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents/software copyrights, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the appropriate ITU-T databases available via the ITU-T website at <https://www.itu.int/ITU-T/ipr/>.

+
+# 6 General aspects
+
+With the rapid growth in the reach of the Internet and accelerated adoption and usage of information and communication technology during the COVID-19 pandemic, the circulation and use of counterfeit and tampered mobile telecommunication/ICT devices has increased considerably. Mobile telecommunication/ICT devices include smartphones and other mobile devices such as tablets with a cellular network interface. In addition to mobile counterfeit ICT devices, the use of stolen devices in mobile networks also poses security and law-and-order problems.
+
+The unchecked proliferation of counterfeit and tampered mobile telecommunication/ICT devices in the public land mobile network (PLMN) is a serious challenge to regulators, law enforcement agencies (LEA) and end consumers that also adversely affects revenue collection and therefore the economy in general. The supply and demand economics of counterfeit and tampered mobile telecommunication/ICT devices complicate the efforts to check the local as well as global market scenario for such devices.
+
+[ITU-T Q.5050] has already considered possible approaches to solving the problem of counterfeit ICT products. In order to have a general understanding of possible directions for creating solutions to combat counterfeit, tampered and stolen telecommunication/ICT devices, Appendix I (clause I.1) provides a general analysis of the mobile telecommunication/ICT device ecosystem and the main stakeholders involved. Knowledge of the stakeholders and their roles in the ecosystem will allow us to define the general contours of the reference unified platform framework (RUPF).
+
+This Recommendation aims to provide a comprehensive approach for combating counterfeit, tampered and stolen mobile telecommunication/ICT devices with a consumer-centric unified platform framework. By this proposed approach, the source of counterfeit and tampered mobile telecommunication products can also be assisted in tackling such issues, to the extent possible, in the markets where they are manufactured and from which they are exported and in the countries in which they are sold.
+
+It is very difficult for anyone to differentiate between authentic and counterfeit or tampered mobile telecommunication/ICT devices by inspecting or testing them because counterfeiters attempt to create products very similar to the genuine device and even provide similar documentation and packaging. It is crucial that these factors are considered when deploying technology solutions to avoid creating more problems for users and genuine manufacturers than those the solutions aim to address.
+
+However, in order to effectively check the proliferation and to combat the induction of counterfeit and tampered ICT including stolen devices in the mobile network, the information technology (IT) solution framework should enable consumers to verify the authenticity of any mobile telecommunication/ICT device ubiquitously while making purchasing decisions.
+
+Consumers are the most affected and vulnerable stakeholder in the telecommunication/ICT mobile device ecosystem and a consumer-centric approach can play an important role in combating the proliferation of counterfeit and tampered mobile telecommunication/ICT devices. This is because
+
+they often pay similar prices for the counterfeit devices while suffering consequences including compromised performance, security and privacy. Thus, the success of any solution to combat counterfeit or tampered mobile telecommunication/ICT and stolen devices lies in the empowerment of the end consumer through tools and awareness so that they can take informed decision while buying mobile telecommunication/ICT devices. Such a solution should cover all possible local and global scenarios through which counterfeit mobile telecommunication/ICT devices may enter the mobile network ecosystem through unauthorized channels. Further, the rejection of such devices by consumers, based on their awareness and empowerment with enabling tools, will also create a huge disincentive to the unauthorized manufacturing and trade of counterfeit and tampered telecommunication/ICT devices.
+
+The ecosystem of counterfeit and tampered mobile telecommunication/ICT devices is focused on exploiting susceptible consumers. Due to a lack of consumer awareness and ignorance combined with the cheaper cost of counterfeit and tampered devices, consumers are enticed to buy them. Thus, consumers may suffer possible negative impacts when using counterfeit and tampered device. (Appendix I (clause I.2)).
+
+Therefore, the Member States either planning or implementing countermeasures for restricting the usage and proliferation of counterfeit and tampered telecommunication/ICT device should consider a holistic multipronged, consumer-centric approach while implementing a relevant IT solution framework.
+
+# **7 Reference unified platform framework (RUPF) requirements**
+
+Considering the above stakeholder analysis of the counterfeit and tampered telecommunication/ICT device ecosystem and possible roles of that can be played by the different stakeholders in combating this menace, the requirement for RUPF and different reference data sources are discussed below.
+
+### **7.1 Type allocation code (TAC) database**
+
+The type allocation code (TAC)<sup>1</sup> is the first 8 digits of the international mobile equipment identity (IMEI) (which is 14 digits plus 1 check digit in length) which identifies the device model, brand owner and original equipment manufacturers (OEM). A TAC is allocated for a specific device model and brand owner. The TAC database and IMEI are important for the functioning of mobile devices and the mobile ecosystem. Device brand owners have to apply for TAC even for outsourced manufacturing. Therefore, access to the consolidated global TAC database provides the basic reference data for TAC codes against which the validity of any TAC code, used in any mobile telecommunication/ICT device, can be verified. A TAC database can provide important information about a device including its manufacturer, model name, TAC allocation date, OEM, subscriber identification module (SIM) slots, type of universal integrated circuit card (UICC) or embedded universal integrated circuit card (eUICC) operating system, frequency bands and radio interfaces. These details may be used effectively by RUPF and thereby help customs, LEAs and other stakeholders to differentiate counterfeit devices from genuine ones.
+
+### **7.2 ICT device verification repository of brand owner or original equipment manufacturers**
+
+The TAC database is made up of the first 8 digits of the IMEI based on the details of ICT devices provided by the device brand owners or manufacturers concerned. The remaining six digits and one check digit of IMEI are assigned by the brand owners or manufacturers themselves according to the actual utilization or production of the respective model of that device. Therefore, it is possible that
+
+---
+
+<sup>1</sup> Global System for Mobile Communications Association (GSMA) is responsible for allocating type approval codes (TAC) to mobile device manufacturers.
+
+the TAC database may show the device manufacturer or brand owner, model and other device related details, as filed by brand owner or manufacturer for allocation of TAC, even when the actual mobile telecommunication/ICT device may not have been produced or shipped to market. Therefore, only the device brand owner/OEM can provide the authentic reference database or repository of actually manufactured and shipped mobile telecommunication/ICT devices in the market. Thus, a more reliable verification of an IMEI may be made by combining the TAC database and the OEM's manufactured device repository or database.
+
+This device repository may be queried on demand or periodically synced by the unified platform for the verification of ICT devices by LEAs, customs and excise, regulators and consumers. The brand owners/OEMs may already be maintaining such a device database internally for the purpose of sales and after-sale warranties or lifecycle support for their telecommunication/ICT devices. Therefore, this can easily be made available to the authorized agency of Member States in a secure manner to facilitate the implementation of a unified reference platform framework. Member States may consider addressing this requirement through enabling a techno-policy framework if necessary. Measures are required to ensure security of the data.
+
+### **7.3 National and international stolen device database**
+
+To create disincentives for theft of mobile telecommunication/ICT devices and mitigate the use of stolen mobile devices, the unified platform should be used effectively to track and create a block list of stolen or lost devices to enforce the policy with the help of mobile network operator (MNO) - equipment identity register (EIR) capabilities. To implement this feature, a user interface may be used for consumers to report stolen or lost devices. Based on the applicable framework, the entry in the stolen/lost device database can be made for example by an LEA or by the device owner after due authentication of device ownership. For example, a consumer could register a stolen device on the online platform by filing its details along with a copy of the report filed with a LEA and proof of identity. As soon as the complaint has been verified by the LEA concerned, the entry is pushed to the relevant stolen device list of the central EIR. Per LEA requirements, the device can either be placed in a blocked list or in a tracked list, which are further replicated to the MNO-EIRs at a national and international level.
+
+If the mobile telecommunication/ICT device is tracked and recovered by an LEA or by users themselves, the IMEI of the device may be removed from the stolen or lost device database and from the blocked list through the same user interface. This process provides flexibility and convenience to consumers in lodging complaints and to LEAs in effectively dealing with increasing numbers of cases of stolen or lost mobile telecommunication/ICT devices.
+
+The IMEIs of non-recovered devices can be placed in the permanent blocked list of the central EIR so that valid unique mobile device identifiers cannot be replicated in counterfeit or tampered ICT mobile devices in future.
+
+### **7.4 National unified platform with central EIR**
+
+The central EIR will have interfaces with relevant reference data sources and will update or synchronize data with a defined periodicity or query online as per agreed arrangements between Member State and reference data providers concerned. The main reference data source will be the TAC database. Based on the overall functional requirements, central EIR may also maintain additional details, which may include but not limited to:
+
+- a) Permitted list, for devices that are allowed to register in the mobile network.
+- b) Blocked list, for devices that are prohibited to register in the mobile network based on defined criteria by the Member State concerned.
+- c) Tracked list, for devices with an intermediate status (when it has not yet been defined in which of the lists – blocked list or permitted list – the device should be placed). For example,
+
+a recently stolen mobile device may be placed in the tracked list so that it can be tracked when it connects to a mobile network.
+
+- d) Lost or stolen device list, for lost or stolen devices in the country, with periodic updates in status.
+- e) Lost or stolen device list, for lost or stolen devices in other countries, with periodic updates in status. This interface could be established via the central equipment identity register (CEIR) or via each MNO-EIR.
+- f) Subscriber number or mobile station international subscriber directory number (MSISDN), to link the device and user or owner at any given point of time for lost, stolen or counterfeit devices.
+- g) Details of the importer or local manufacturer who brought the device into the country/market.
+
+The majority of these lists are dynamic in nature and devices may move from one list to another based on defined criteria that can be applied using events detected or reported through the unified platform. For example, when a lost or stolen device is recovered and returned to its authorized owner, it is removed from the lost/stolen device list and/or the tracked list and moved to the permitted list so that it can be used in mobile networks. These centralized lists will be synchronized by MNO-EIRs with a defined periodicity for making decisions on whether to allow the device in the mobile network or not. The frequency of the update from source reference data and MNO-EIR update and the type of lists to be maintained in central EIR may be decided based on national requirements. These are the critical input parameters for platform architecture and hardware dimensioning and should be given due consideration when finalizing platform functional requirements and solution architecture.
+
+### 7.5 Mobile network operator's equipment identity register
+
+Third generation partnership project (3GPP) Technical Specifications provide that network operators can make use of IMEIs to exercise control on the entry of mobile devices to the MNO network. It specifies requirements for three registers, i.e., a permitted list, tracked list and blocked list. The permitted list is composed of all number series of equipment identities i.e., TAC that are permitted for use. This can be sourced from the TAC database. The blocked list contains all equipment identities i.e., IMEIs that belong to equipment that need to be barred. This list can be generated at the central database according to the regulatory frameworks in the respective Member State. Equipment on the tracked list is not barred (unless it is on the blocked list or not on the permitted list) but is tracked by the network (for evaluation or other purposes).
+
+While central EIR may have multiple lists to provide a wide range of information to LEAs and consumers, it ultimately derives the permitted, blocked and tracked lists through overall information. These three lists are replicated or copied in the MNO-EIR for exercising actual control for allowing or denying access in the mobile network. Per 3GPP specifications, it shall be possible to perform the IMEI check at any access attempt, except international mobile subscriber identity (IMSI) detach and even during an established call at any time when a dedicated radio resource is available. The network is required to terminate any access attempt or ongoing call when receiving the answers "blocklisted" (i.e., on the blocked list) or "unknown" equipment (i.e., not on the permitted list) from the EIR. The MNO can capture logs and pass relevant data sets such as geographical details and MSISDN to the RUPF in case of an access attempt by blocklisted or tracked-listed devices, per policy. This will enable the performing of analytics and tracking of counterfeit devices through the unified platform.
+
+### 7.6 Stakeholder interface(s) for mobile telecommunication/ICT device verification
+
+Countermeasures against the proliferation of tampered or counterfeit and stolen ICT devices will require considerable collaborative efforts by all stakeholders, especially TAC allocating bodies, OEMs, LEAs, MNOs, customs and excise and regulators. Therefore, the platform should be designed to facilitate collaboration and provide intuitive, easy to use and secure interfaces. The unified platform
+
+interfaces can broadly be grouped into two categories, i.e., system-system interfaces and system-user interfaces, as depicted in Figure 1.
+
+The interfaces should provide secure role-based access to users based on their reasonable requirements as permitted under the techno-policy framework. For example, at the user-system interface, the platform may provide authorized access to LEAs or customs officials for the verification of individual devices as well as bulk verification, but the consumer may only have access to check individual devices and may have a possible limit on the number of verification attempts allowed per day. Depending on the purpose and use, the interfaces need to be secured through encryption and authentication to protect the data available on the platform. The relevant access logs and audit trails may be recorded in the platform and analysed in near real-time to track and mitigate any malicious activities trying to misuse these interfaces.

+
+# **8 Reference unified platform framework (RUPF)**
+
+Considering the roles of different key stakeholders and unified platform requirements discussed in Appendix I, a proposed reference framework is given in Figure 2.
+
+With the implementation of this RUPF, it will be possible for key stakeholders i.e., LEAs, customs and excise, and regulators to effectively implement comprehensive countermeasures to combat counterfeit and tampered telecommunication/ICT devices. Customs and excise authorities or other enforcement entities will be able to check against the device permitted list to verify whether the identifiers of the devices, whether produced locally or imported, have been legitimately allocated and that their make and model match with the details recorded in the TAC database and OEM repository. The data sourced from the TAC database and OEM repository of devices actually manufactured will provide a reliable reference against which any mobile telecommunication/ICT device can be verified using secure interfaces provided by the RUPF.
+
+The RUPF can also be used effectively to track the lost or stolen devices and restrict their use in mobile networks by integrating national and international lost or stolen device databases with the platform. This database can be integrated with the RUPF, if already available or it can be implemented as one of the modules of RUPF.
+
+The ubiquitous access of RUPF to consumers will enable them to check whether the mobile telecommunication/ICT device (which may be new, second-hand or refurbished) that they are buying is counterfeit or stolen. If it is stolen or counterfeit, consumers will be protected from buying counterfeit, tampered or stolen devices and will also be able to report to LEAs that could take action to track and recover such devices. This will act as a strong deterrent against thieves and counterfeiters.
+
+The RUPF concept is based on a consumer-centric approach. The counterfeit mobile telecommunication/ICT device ecosystem has sustained itself over a certain period and is further proliferating mainly due to the cost advantage such devices command over genuine devices. Generally, counterfeiters target low- and middle-income group consumers for selling counterfeit or
+
+tampered devices. Due to a lack of awareness about the risks associated with using counterfeit devices and because of the price advantage, consumers are attracted to buy such mobile telecommunication/ICT devices.
+
+To empower the consumer and ensure adoption, the simplicity and ease of use of the RUPF, preferably provided in the local languages, is an important consideration. Therefore, the platform should provide secure and simple interfaces for interaction with the end consumers of mobile telecommunication/ICT devices.

+
+### 8.1 Reference unified platform framework overview
+
+The brief overview of key framework components is given below:
+
+- i) **TAC database:** List of TAC codes allocated for a specific device model and brand owner.
+- ii) **National/international stolen device database:** This is the module for reporting lost or stolen devices and for their subsequent lifecycle management.
+
+- iii) **OEM repository (1,2...n):** OEM repositories are the databases maintained by OEMs to provide reference data about devices that were actually manufactured or shipped to the market against the TAC code(s) allocated to them.
+- iv) **Customs and excise, LEA, regulator:** Customs and excise, LEA, regulator use the platform for taking counter measures against the proliferation of tampered telecommunication/ICT and stolen devices.
+- v) **Consumer:** Consumers may seek information about authenticity or status (i.e., stolen or not) of any telecommunication/ICT device.
+- vi) **National unified platform:** The national unified platform consists of the following submodules.
+  - a) **Imported device IMEI list:** The imported device list consists of the IMEI or IMEI range(s) of devices imported with authorization to the country. This list may be provided by the customs authorities or by any other authority responsible in the Member State concerned. With this list, it can be verified whether the device has been imported with authorization to the Member State or not. It is also possible to integrate the RUPF for automatic fetching of these details from the system maintaining such a list, if it is maintained by the stakeholders concerned.
+  - b) **Locally manufactured device IMEI list:** The locally manufactured device IMEI list is the database of IMEIs or IMEI range(s) of mobile telecommunication/ICT devices that have been manufactured within the Member State. A Member State may mandate local manufacturers to update such details in the platform itself if no separate reporting system is implemented for this.
+  - c) **Lost and stolen device list:** This database is replicated from the national and **international** stolen device database if it is implemented outside the RUPF, otherwise it can be a module within the RUPF with the features described in clause 7.3.
+  - d) **Permitted list:** The permitted list is created in the central equipment identity register (CEIR) based on the regulatory framework in Member State. It is a list of mobile telecommunication/ICT devices that are allowed to register in the mobile network. This list is synced or updated by MNO-EIR at a defined frequency or upon defined events (see clause A.2.3).
+  - e) **Blocked list:** The blocked list is created in the CEIR based on the approved regulatory framework of the Member State. It is the list of devices that are prohibited to register in the mobile network. This list is synced or updated by MNO-EIR at a defined frequency or upon defined events (see clause A.2.3).
+  - f) **Tracked list:** The track list is the list of mobile telecommunication/ICT devices that are to be tracked for further action e.g., stolen or lost devices. Such devices are allowed to register in the mobile network for a defined period (see clause A.2.3).
+  - g) **MSISDN-IMEI map:** In order to handle the cases of devices with tampered or replicated unique identifiers such as the IMEI, it is a pre-requisite to ascertain genuine and counterfeit or tampered devices and only allow registration by genuine devices. In such cases, the devices with combination of IMEI and MSISDN may only be allowed (see clause 7.4).
+  - h) **Query logs:** Query logs contain raw meta data that can be used for further analytics and correlation. For example, when a query is made with <IMEI> by a consumer, the following logs may be generated if response is <N> or <Lost>.
+
+#### **IMEI, MSISDN, 'N', 'L', location latitude/longitude**
+
+Similar logs in the required format may also be generated for different relevant scenarios. These logs can be analysed to generate time alerts to concerned agencies and discover patterns such as geo-hotspots of usage of stolen or lost devices.
+
+- vii) **MNO-EIR:** The MNO-EIR holds various lists of mobile devices, such as the permitted list, blocked list or tracked list, per 3GPP Technical Specifications. It interfaces with the CEIR for the replication of these lists based on specified interfaces [b-ITU-T Q Suppl. 76]. The MNO-EIR holds the updated lists for enforcement in the mobile network per the regulatory policy (see clause 7.5).
+- viii) **System–system interfaces:** System-system interfaces are the interfaces through which the RUPF interacts with other systems (see clause 7.6).
+- ix) **System–user interfaces:** System-user interfaces are the interfaces through which RUPF users such as consumers, LEAs and regulators interact with the RUPF (see clause 7.6).
+- x) **Query and user log analytics and alert:** The interactions of different categories of users with the platform will result in the generation of various activity and query logs. The correlation and analytics of such logs may be used to discover actionable patterns that may be used for pre-emptive actions by LEAs. For example, the spatial correlation of the queries in which the device was found to be counterfeit may reveal geographical hotspots for counterfeit, stolen or tampered devices.
+- xi) **Consumer interfaces and interactions:** The suggested RUPF architecture is aligned with the objective of consumer empowerment as an anytime, anywhere tool for verifying any mobile telecommunication/ICT device. Therefore, consumer interfaces should be designed to provide simple and intuitive interaction. The consumer should be able to use platform in the following interaction scenarios:
+  - a) **Online through desktop/mobile:** For consumers who may not have access to an MNO subscription and want to verify details of any mobile telecommunication/ICT device, the platform should provide a secure interface through a website that can be used through the Internet. The suggested query and response mechanism is already covered in Figure 2.
+  - b) **Mobile application:** To provide a better user experience and comprehensive tools to the consumer, a mobile application, closely integrated with the RUPF, may serve as a good tool for the consumer interface, as well as for relevant data capture in a platform-like location with the permission of consumers. The mobile app may bundle relevant features for mobile telecommunication/ICT device verification querying, reporting of lost or stolen devices, reporting of details about any counterfeit devices with due verification and reporting recovery of stolen or lost devices etc. The mobile application can be used by both types of consumers, i.e., those with an MNO subscription or those with only having Wi-Fi Internet access.
+  - c) **Short message service (SMS) interface:** Since a significant number of feature phones are still in use, especially in developing countries, an SMS interface is an essential requirement of the RUPF. The query format for the SMS-based interface should be simple and require a minimum number of input text or numbers, for example, only the IMEI. The response should be provided in a simple format, and preferably in a local language for better understanding and to have the desired impact on consumers. Member States may waive SMS charges for consumers for one or two queries per day or week if required under consumer awareness programmes.
+  - d) **Unstructured supplementary service data (USSD) interface:** Though an SMS-based query service for consumers can be used on both smartphones and feature phones, a USSD interface may be considered as an alternate interface. Consumers can use such an interface to query the RUPF to obtain details only for the mobile telecommunication/ICT device through which the query is triggered. The possibility to provide simple USSD code to invoke a USSD query exclusively to the RUPF may be explored. On invoking a query through the USSD code of the service, IMEI details may be automatically fetched from the device, which will eliminate any wrong input scenarios. This consumer interface
+
+will enable queries even by the consumers with the lowest literacy and will bridge the possible awareness divide about the risks involved in counterfeit mobile telecommunication/ICT devices.
+
+## 8.2 Key platform features
+
+The following key guiding principles may be considered while preparing the solution architecture of the RUPF.
+
+- i) The platform should provide simple and intuitive interfaces to stakeholders covering possible scenarios such as the limited availability of Internet access and the absence of an MNO subscription.
+- ii) To overcome the limited availability of Internet access, SMS/USSD channels may be made part of network interfaces for consumers to access the platform. This will broaden accessibility to consumers and other stakeholders.
+- iii) In scenarios where a consumer has no MNO subscription, Wi-Fi/Internet channels may be used by them to access the platform through desktop or mobile device. This will enable a wider range of access channels for different types of mobile telecommunication/ICT devices especially for rural populations using low-cost feature phones.
+- iv) The platform should have secure interfaces with the national and international stolen device database, the OEM's IMEI repository of manufactured devices, the OEM's country-specific export, locally manufactured IMEI device database and TAC database.
+- v) If OEMs do not have online reference repositories of mobile telecommunication/ICT devices that have actually been manufactured, they can be provided with secure interfaces in the platform to upload IMEI range(s) of manufactured mobile devices against their reference entry in the TAC database.
+- vi) The LEA, customs and excise and regulator should be able to access the platform with the facility for single as well as bulk mobile telecommunication/ICT device verification.
+- vii) Consumers may be provided with only single device enquiries, with required checks such as one-time password (OTP) or captcha to avoid automated query attempts on platform and consumer traceability.
+- viii) The query to the platform may be sent in a form such as <IMEI> through any device, e.g., computer, mobile or laptop.
+- ix) A single query to platform may automatically split in multiple queries internally e.g., to the stolen and lost device database, the OEM repository or the TAC database. The platform may return a consolidated response to the user with relevant details in a format such as <Make, Model, Valid IMEI (Y/N), Stolen/Lost(Y/N)>, as applicable.
+- x) The unified platform may expose secure APIs to LEAs, customs and excise authorities, and regulators for bulk or IMEI range verification.
+- xi) The verification logs generated in the platform through consumer queries and use by LEAs and customs and excise may be used to feed an analytics module that may be built upon the platform to find patterns to identify the players involved in these unauthorized activities.
+- xii) The consumer queries to the platform, if in the stolen or lost device database, may also be used to trigger alerts to concerned LEAs to geolocate the stolen or lost ICT devices and their users.
+- xiii) To encourage OEMs to support the verification of ICT devices, security or trust rating assignment may be considered by regulators. The ratings may be based on objective and measurable criteria evolved after stakeholder consultation.
+
+- xiv) To avoid inconvenience to international in-roamers, their mobile telecommunication/ICT devices may be kept outside the framework of the valid IMEI check while they are roaming in foreign MNOs networks.
+
+# **9 RUPF security and privacy considerations**
+
+The national unified platform implementation based on the framework provided in Figure 2 will host important data sourced from different stakeholders and consumers, including from the IMEI database and OEMs. Therefore, the platform is likely to be a target of cyberattacks by different sources and impacted parties. Since it is a countermeasure against counterfeit and stolen ICT devices, the entities involved in such activities will also target the system. Counterfeiters may also try to gather the details of TAC codes and valid IMEI range being maintained in CEIR to use them for IMEI replication or cloning. Therefore, the platform implementation should adopt a security-by-design approach. The platform security may consider the latest practices and standards regarding cybersecurity, including role-based access, secure APIs and dual-factor authentication.
+
+The RUPF is not expected to store any consumer-specific data such as name, address, date of birth or any other personal identifier. Only IMEI-MSISDN combinations may be captured on a case-to-case basis for stolen or blocklisted devices per the requirements of platform features and functionalities. Therefore, the platform framework duly safeguards the privacy of individual consumers. The location details of only blocklisted or permitted devices may be required by LEAs as permitted by the legal framework to act against unauthorized activities.
+
+## Annex A
+
+## Issues (aspects) and scenarios for the implementation of a reference unified platform framework
+
+(This annex is an integral part of this Recommendation.)
+
+### A.1 Key considerations when implementing a reference unified platform framework
+
+#### A.1.1 Stakeholder consultation and onboarding
+
+The implementation of a RUPF is a collaborative effort by key stakeholders, which include consumers, regulators, MNOs, TAC allocating bodies, OEMs, customs and excise, and LEAs. Therefore, it is important to establish ongoing communication channels with all stakeholders involved prior to actual implementation so that agreements can be reached on the role and responsibilities of each stakeholder. This will enable faster roll-out and implementation of the technology platform with minimal disruption in the ecosystem, especially to the consumers and OEMs of genuine devices.
+
+#### A.1.2 Enabling regulatory frameworks
+
+The enforcement of any countermeasure affecting consumers or other stakeholders, such as disabling existing identified counterfeit devices in the MNO network or disallowing the entry of new counterfeit ICT devices into the MNO network, will require the enabling support of an appropriate regulatory framework. The enabling regulatory framework may include but is not limited to the following provisions to:
+
+- i) Allow restrictions on the entry of any new counterfeit or tampered devices with replicated identifiers or stolen telecommunication/ICT devices in MNO networks;
+- ii) Allow restrictions on the import, manufacturing, circulation and sale of counterfeit mobile telecommunication/ICT devices and accessories in the market that are not compliant with a country's legislative and regulatory framework;
+- iii) Allow the establishment of a unified platform and stakeholder responsibilities to support measures to combat the proliferation of tampered and counterfeit ICT devices;
+- iv) Allow action against the tampering and replication of unique identifiers.
+
+Member States may also consider technical regulation, if required, to ensure compliance with the IMEI format and requirement of their online verifiability in collaboration with OEMs to minimize IMEI tampering and prevent devices with tampered or replicated identifiers from accessing mobile networks.
+
+#### A.1.3 Consumer awareness and participation
+
+Consumer education and their active participation supported by a RUPF can play central a central role in combating the proliferation of counterfeit, tampered and stolen mobile telecommunication/ICT devices. Due to their lack of awareness of the possible adverse effects of using counterfeit ICT devices, consumers are the most vulnerable stakeholder. The use of tampered and counterfeit ICT devices impacts consumer safety, security and privacy including quality of experience and network performance. Therefore, consumers should be encouraged, through awareness campaigns and consumer education, to participate and play an active role in combating the proliferation of tampered, counterfeit and stolen ICT devices. The RUPF will further empower them by providing tools for verifying devices at any time in any place through simple user interface(s). Easy access to a tool to check if a device is reported stolen may prevent a consumer from buying it.
+
+Regulators and MNOs may run awareness campaigns periodically for different target groups of consumers and arrange workshops for consumer self-help groups. The campaigns may provide information on tools available to check whether an ICT device is counterfeit or reported stolen and
+
+on the reporting mechanism(s) upon detection of any device flagged by the RUPF as tampered or counterfeit or stolen or as being a device with replicated unique identifier. The MNOs may be mandated to include relevant information in their customer welcome kit, welcome message and post-paid bills. Retail stores and OEMs should be encouraged to participate in raising consumer awareness about risks associated with using counterfeit ICT devices. Additionally, consumers can be made aware of their obligations and rights regarding the use and acquisition of mobile telecommunication/ICT devices. Remedial actions, such as disallowing the devices in mobile networks or disabling existing devices, should be considered only after consumer awareness campaigns and following advance notice, so that there is zero or minimal impact on consumers.
+
+#### **A.1.4 Identification and enforcement actions against producers and traffickers of counterfeit devices**
+
+In order to break the vicious cycle of production and trafficking of counterfeit mobile telecommunication/ICT devices, stakeholders are required to take coordinated actions at every possible checkpoint in line with enabling the regulatory framework of the Member State. To enable better coordination, there is a need to establish an agreed process to implement countermeasures. To trace back the source and remove producers and traffickers from the market, checks at the following points are important:
+
+- Local manufacturing units before products enter the local market or are exported;
+- Ports of entry for imported mobile telecommunication/ICT devices;
+- Entry to the mobile network.
+
+In addition, analytics on consumer complaints and feedback captured as a result of online verification on the RUPF and market surveillance, as used in [ITU-T Q.5050], can play an important role.
+
+Since counterfeit mobile telecommunication/ICT devices often cross different countries before being sold in the market, it is crucial to establish strong collaborations between the agencies concerned in other countries of origin or transit to trace the source of production and the channel(s) of trafficking.
+
+#### **A.1.5 Implementation of a reliable unique identifier**
+
+The secure, verifiable, and persistent unique identifier is the cornerstone of any solution to combat tampered or counterfeit mobile telecommunication/ICT devices. The lack of such reliable tamperproof unique identifiers in mobile telecommunication/ICT devices is being extensively exploited by counterfeiters and is the biggest bottleneck in initiating effective countermeasures. With the widespread use of the latest ICT mobile devices using 5G and Internet of things (IoT) / machine-to-machine (M2M) technology, the impact of counterfeit devices may pose a greater challenge for the security and privacy of consumers; an additional impact is the foregone tax revenue. Therefore, it is imperative that standardization bodies and OEMs are recommended to take urgent actions to ensure the implementation of secure, verifiable and persistent unique identifiers in mobile telecommunication/ICT devices that cannot be changed by unauthorized entities. Since IMEI is an identifier that is used by the mobile network and is visible on mobile telecommunication/ICT devices, it is currently easily used for the replication and manufacturing of counterfeit mobile telecommunication/ICT devices.
+
+Therefore, OEMs and manufacturers are recommended to store the unique identifier on a secure element on the mobile device and implement security measures, to the extent technologically feasible, to detect tampering. The identifier issuer entity is recommended to implement a process that ensures the verifiable, correct and secure implementation and use of these unique identifiers. Further, standard development organizations such as 3GPP may consider the issue and develop a roadmap for the improvement or revision of an existing scheme for the unique identification of mobile telecommunication/ICT devices based on only IMEI, which are being extensively used for replication or production of counterfeit ICT devices.
+
+#### **A.1.6 Collaboration with authentic ICT device manufacturers**
+
+Sometimes, action against counterfeit ICT devices may result in undesired effects on authentic ICT device manufacturers caused by compliance, enforcement and surveillance.
+
+Therefore, collaboration and active support of OEMs is important to ensure the effective implementation of technical solutions and to ensure action towards the implementation of tamperproof and verifiable unique device identifiers. Efforts should be made to minimize any additional cost to manufacturers to comply with the regulatory requirements while meeting the overall objectives of driving the counterfeit, tampered and stolen ICT devices out of circulation and use in mobile networks.
+
+#### **A.1.7 Avoiding technical barriers to trade**
+
+Though the measures to combat the proliferation of counterfeit or stolen devices is in the interest of global consumers and Member States, regulatory measures to counter the issue of counterfeit mobile telecommunication/ICT devices should also be evaluated to ensure that they do not result in undesired effects on the import, export and use of genuine ICT devices, which may constitute a technical barrier to trade (TBT) as defined by the World Trade Organization (WTO) trade-related aspects of intellectual property rights (TRIPS) [b-WTO-TRIPS].
+
+#### **A.1.8 Collaboration with law enforcement agencies to mitigate negative impacts on consumers**
+
+Since current mobile devices store sensitive personal data and allow access to various financial and governmental services, it is recommended that LEAs are connected to the RUPF not only to request the inclusion of counterfeit, tampered and stolen devices on databases but also to receive up-to-date information on irregular devices included by other sources and, based on this information, are able to notify relevant stakeholders to avoid additional negative impacts for the consumer, such as irregular financial or governmental transactions using the data and applications on the stolen device.
+
+### **A.2 Possible approaches for RUPF implementation**
+
+Unified platform implementation may be carried out in a phased manner or in one go based on the requirements of the Member State in question. The implementation options described in clauses A.2.1 to A.5 may be considered while rolling out a unified platform framework.
+
+#### **A.2.1 Full implementation**
+
+In the full implementation option, all modules of the platform including central and MNO-EIR, integration with TAC database, stolen or lost device database and OEM repositories will be required for system-system interfaces. The user-system interfaces will be required to support stakeholder queries through various channels as elaborated in the framework. The advantage of this approach is that stakeholders can obtain complete details of the device under verification.
+
+For example, when a consumer tries to lodge a complaint about a stolen device, an alert may be sent to the consumer and LEA that the device is counterfeit or tampered and that a report is being made. In this scenario, to discourage the use of counterfeit or tampered devices, LEAs may give priority to tracking genuine devices while further analysis on purchase history may be carried out for counterfeit or tampered devices. The platform will enable a progressive build-up of a national database of counterfeit, tampered and lost devices that can be shared with other Member States for blocklisting in their network based on mutual collaboration. Suitable interfaces may be developed in the platform for the secure exchange of blocklisted unique identifiers across Member States for the seamless exchange of updated lists periodically at an agreed frequency based on operational considerations.
+
+#### **A.2.2 Phased implementation**
+
+In a phased implementation, Member States may identify the problem statements to be addressed in order of priority and pick the relevant modules from the reference framework for implementation.
+
+However, the solution architecture should be prepared considering future module addition to avoid architectural rework. System–system and user–system interfaces may be chosen per requirements for initial implementation, with a suitable provision of horizontal and vertical scalability.
+
+For example, if the priority is to address the issue of stolen mobile devices, the stolen device database, consumer and LEA interfaces may be developed and rolled out initially. In one or more subsequent phases, the solution may be scaled up to implement a TAC database and relevant interfaces including the required expansion of IT infrastructure to host the additional central EIR Database.
+
+If OEM repositories are not readily available, the following alternate options may be considered in the interim period:
+
+- Creation of a reference OEM repository database in the RUPF by integrating a database of imported and locally manufactured devices; or
+- OEMs may be mandated to upload the manufactured or imported device details in the form <IMEI from, IMEI to> in the national database for devices imported in the country or manufactured locally.
+
+#### A.2.3 CEIR-MNO-EIR data exchange
+
+The national CEIR and MNO-EIR need to exchange data seamlessly for the successful implementation of the RUPF in multi-operator scenarios. In the national unified platform, CEIR is responsible for the generation of different lists, i.e., the permitted list, tracked list and blocked list, based on various input and reference data sourced by RUPF. The MNO-EIRs will periodically sync these lists from CEIR in their respective network as soon as possible, preferably within 24 hours or less. The following criteria may be considered by CEIR for the generation of various lists:
+
+- i) **Permitted list:** To start with, a permitted list may be generated through the specific TAC codes or range of valid TAC as provided by the TAC database. This list may be narrowed down further by maintaining the range of valid IMEIs against the respective TAC code as updated by respective OEM. Any IMEI without a valid TAC code and valid IMEI range, as provided by the entity to which the TAC code is allocated, may be considered a counterfeit mobile telecommunication/ICT device and may be denied access to the MNO network. To facilitate the availability of information of the IMEI range of devices actually manufactured against the allocated TAC codes and its uniform dissemination globally, TAC allocating bodies may consider maintaining the list of IMEIs.
+- ii) **Blocked list:** The mobile telecommunication/ICT devices that do not fall in the criteria of the permitted list as decided by a Member State in line with the regulatory framework may be denied access by the MNOs per the local regulation and after providing a grace period for old or existing mobile telecommunication/ICT devices and consumer awareness. However, there are scenarios in which even devices with valid IMEIs or specific types of invalid IMEIs are required to be denied network access. For example, a stolen mobile device will pass the permitted list check, but it needs to be denied access if required by LEAs. Such IMEIs will be entered in the 'blocked list' of the CEIR which will be replicated by MNO-EIRs. The default blocked list may include:
+  - a) All zero IMEI;
+  - b) Null IMEI;
+  - c) IMEIs of stolen or lost devices as approved by LEAs in a framework of regulation subject to dynamic update based on their recovery.
+
+Based on the regulatory framework, the conditions for mobile network access by mobile telecommunication/ICT devices may further be tightened by treating the IMEI range, provided by a brand owner or manufacturer of mobile telecommunication/ICT devices against respective TAC codes, as valid a reference rather than only checking against the valid TAC codes.
+
+- iii) **Tracked list:** Sometimes it may be required to allow access to mobile telecommunication/ICT devices though they may be suspected of replicating of unique identifiers or cloning. For example, a mobile device, though valid per the permitted list, may be available in the network for a given IMEI-IMSI combination while one or more other devices are also accessing the network with the same IMEI but with different IMSIs. In this scenario, the MNO must perform analysis and due diligence before blocking access to a specific device. Therefore, such mobile devices may be placed initially in the tracked list for collection and analysis of their usage and user data. In such a scenario, the blocked list entry may require a combination of IMEI-IMSI for blocking a specific mobile telecommunication/ICT device.
+
+#### **A.2.4 Tampering and replication of unique mobile telecommunication/ICT device identifiers**
+
+The consumer-centric national unified platform based on the RUPF can be effectively utilized as a tool to detect the tampering and replication of a unique mobile telecommunication/ICT device identifier. The use of invalid IMEIs in mobile telecommunication/ICT devices will be reduced to a large extent with the effective implementation of a RUPF in Member States. However, counterfeiters may still try to use replicated IMEIs, which will pass the criteria of being on the permitted list as discussed in clause A.2.3. Therefore, OEMs, in collaboration with standard development organizations, need to consider innovative ways to distinguish between their own genuine product and one with a tampered or replicated IMEI with the highest degree of assurance.
+
+One possible option could be to use, along with the IMEI number, a combination of one more unique identifiers that can be assigned by the OEM. Such an identifier is to be securely stored on a device in an encrypted form and should only be accessible to the respective OEM. To check whether the mobile telecommunication/ICT device has a tampered or replicated IMEI, OEMs can provide a facility for online verification by MNOs or LEAs or through the national unified platform, in line with a national regulatory framework, so that the mobile telecommunication/ICT devices with replicated or tampered IMEIs can be detected and identified for denial of access by MNOs. The reporting and alerting feature of the platform can be used for the timely dissemination of information to LEAs for tracking and identifying culprits. [ITU-T Q.5052] describes a broader set of actions to address this issue.
+
+#### **A.2.5 Use of platform to control the unauthorized use of SIM boxes**
+
+SIM boxes are being used for conducting telecom frauds. In such frauds, the SIM box is used to divert international calls to a mobile telecommunication/ICT device through the Internet. The SIM box uses many SIMs in the same device, which will also have Internet connectivity at the other side to collect calls from the Internet. For each incoming international call placed through the Internet, the SIM box will originate a mobile call to the destination number in the local network and patch the call. The called party will obtain calling line identification of the local mobile number used in the SIM box, which amounts to calling line identification (CLI) tampering. The SIM box generally uses invalid IMEIs, which can be disallowed through block list entries. Further, platform analytics may be used to identify the use of IMEI patterns in SIM boxes and restrict the unauthorized use of SIM boxes and allow only authorized use through permitted listing.

+## Appendix I
+
+## **Analysis of the mobile telecommunication/ICT device ecosystem and the main stakeholders involved in the use of counterfeit and tampered mobile telecommunication/ICT devices**
+
+(This appendix does not form an integral part of this Recommendation.)
+
+### **I.1 Mobile telecommunication/ICT device ecosystem and key stakeholders**
+
+The understanding of ecosystem stakeholders and their roles will enable a visualization of the broad contours of a unified reference framework. This analysis will help further in the planning and implementation of the solution to address counterfeit, tampered or stolen telecommunication/ICT devices under the reference unified framework. The key stakeholders in this ecosystem and their roles are analysed in clause 7.
+
+#### **I.1.1 Original equipment manufacturers**
+
+Original equipment manufacturers (OEMs) invest time and money in the research, design and development of hardware and software to develop telecommunication/ICT products while counterfeiters copy these products, as closely as possible, to be able to sell their product in markets around the world. The counterfeiters try to tamper or replicate unique mobile/telecommunication device identifiers and software to make a product as close to the genuine device as possible.
+
+Considering the profit margins to such unauthorized entities, it is an economically viable option for counterfeiters to invest in infrastructure and resources to copy the type approval logos and icons, as well as unique device identifiers. The unique device identifiers are often deliberately subverted or even set in blank to be self-programmed in local markets, to evade customs and law enforcement checks at borders. Therefore, consumers, customs and law enforcement officials face a challenge in distinguishing fake identifying marks on such devices from genuine ones.
+
+To evade the monitoring and identification of counterfeit or tampered ICT devices in the mobile network, a common practice of such entities is to tamper with unique identifiers and replicate with one that some genuine devices use so as to authenticate on the telecommunication network in such a way that the counterfeit or tampered ICT devices are recognized by the network as genuine devices.
+
+Considering this, it is recommended that OEMs need to consider innovative ways to be able to distinguish between their own genuine or tampered product and a counterfeit device with the highest degree of assurance.
+
+One possible option could be to use a combination of identifier(s) with the international mobile equipment identity (IMEI) number, which can be assigned by the OEM while securely storing it on the device in an encrypted form. Such additional identifiers should be only accessible to OEMs. To check whether the mobile telecommunication/ICT device is counterfeit or not, OEMs can provide a facility for the online verification of such telecommunication/ICT device by customs, LEAs or agencies authorized by Member States. Thus, OEMs can protect their own interests by implementing reliable mechanisms for device verification and by collaborating with the concerned Member States in the implementation of effective IT solutions. The standards development organizations relevant to these matters, such as 3GPP, may consider developing standards to address the ever-increasing growth of counterfeit and tampered devices in mobile networks.
+
+#### **I.1.2 Counterfeit or tampered mobile telecommunication/ICT device producers and traffickers**
+
+The counterfeit or tampered telecommunication/ICT device producers invest in manufacturing and make efforts to proliferate such devices, mostly through unauthorized channels and using traffickers, to make a profit. With the active support of OEMs in making their devices verifiable online and
+
+authorized enforcement actions by respective Member State including raising consumer awareness, it is possible to identify counterfeit and tampered devices. Accordingly, enforcement actions can be taken against producers and traffickers. This will help OEMs and Member States to reduce economic losses. Such effective measures will prevent consumers from being misled by such counterfeiters and also protect them from possible performance, quality of service, safety, security and privacy related concerns.
+
+#### **I.1.3 Custom and excise agencies**
+
+The customs and excise authorities of Member States are the first point of entry of mobile telecommunication/ICT devices in a country or local market, and therefore, they can play an important role to effectively limit the circulation, import and sale of new counterfeit ICT devices. They need to establish a close collaboration between the authorities responsible for implementing and managing the IT solution per the reference unified platform framework (RUPF) provided in this Recommendation and also with customs counterpart of other countries. Similarly, for the mobile telecommunication/ICT devices produced and sold locally, excise departments of Member States may use the IT platform to ensure that no counterfeit or tampered ICT device is allowed to enter the local market bypassing authorized channels.
+
+Customs and excise authorities, in collaboration with LEAs, can make good use of analytics on consumer query or feedback data generated through their queries to the unified national platform for tracking the entities involved in production and trafficking of counterfeit or tampered telecommunication/ICT devices.
+
+#### **I.1.4 Consumer**
+
+Consumers are the most important stakeholder in the mobile telecommunication/ICT device ecosystem, as they are the party most affected by the use of counterfeit ICT devices and suffer from possible consequences including compromised performance, safety, security and privacy. It is more likely that consumers buy counterfeit or tampered telecommunication/ICT devices unknowingly due to a lack of awareness about possible implications, but they sometimes buy them knowingly due to possible cost advantages. Therefore, to combat the proliferation of counterfeit and tampered ICT devices, the empowerment of the end consumer through tools and awareness is critical. Empowering these consumers with tools and awareness will enable them to take informed decisions when buying any mobile telecommunication/ICT device. Consumer-centric technology solutions may also generate a cascading effect in controlling the proliferation of counterfeit, tampered and stolen mobile telecommunication/ICT devices as the rejection of such mobile telecommunication/ICT devices by end consumers will create a huge disincentive and substantial uncertainties for players involved in the unauthorized manufacturing and trade of counterfeit and tampered ICT devices. In the absence of unified technology solutions, different stakeholders are working in silos and counterfeiters are enjoying some sort of assured global market for counterfeit, tampered and stolen mobile telecommunication/ICT devices.
+
+#### **I.1.5 Law enforcement agencies**
+
+Counterfeit and tampered telecommunication/ICT devices are either imported through authorized channels or generally routed to the destination Member State(s) through unauthorized and fragmented channels. Further, the counterfeit devices may also be assembled or manufactured locally to push them in the local market without authorization or sent to other Member State(s) through different channels. Thus, LEAs have an important role in detecting and curbing the unauthorized local manufacturing or importation of counterfeit devices through unauthorized channels in collaboration with relevant stakeholders. However, in absence of a unified national platform, which can provide mobile telecommunication/ICT device related information verification and related analytics, LEAs may find it very challenging to effectively play their role in curbing unauthorized trade in counterfeit, tampered and stolen ICT devices. RUPF can be used as an effective collaboration platform to serve
+
+concerned stakeholders for the verification, detection, tracking and retrieval of counterfeit, tampered and stolen devices.
+
+LEA should also use the RUPF to receive updated information on stolen and tampered devices and notify other relevant stakeholders (such as financial and governmental service institutions) in order to protect the device owner from negative impacts.
+
+#### **I.1.6 Regulator and government authorities**
+
+Though the technology solutions may provide an enabling framework for disabling the access of counterfeit and tampered mobile telecommunication/ICT devices, regulators and governments may find it difficult to block or restrict the use of such devices in the mobile network operator (MNO) network once they have been purchased by consumers. The increasing volume of unauthorized trade in counterfeit and tampered ICT devices also impacts the revenue collection of Member States by way of avoidance of applicable taxes, and these devices pose a threat to the privacy, security and safety of their citizens. It may also become a threat to national security. The non-availability of a comprehensive techno-policy framework is being exploited by the players involved in these unauthorized activities. Therefore, breaking this vicious cycle through global collaboration for the implementation of techno-policy measures is critical from the point of view of Member States. In a consumer-centric approach, consumers are empowered with tools and awareness so that they can participate actively in combating the proliferation of counterfeit and tampered devices along with other stakeholders. With consumer education and enabling tools, it will be easier for regulators and governments to implement techno-policy measures effectively without any significant negative impact on consumers and authorized manufacturers.
+
+#### **I.1.7 Mobile network operators**
+
+The MNOs manage the network in which ICT devices are used by consumers to avail themselves of telecommunication services. In countries where governments conduct initiatives to block tampered or counterfeit ICT devices, the MNOs are the stakeholders responsible for implementing technical means, through their equipment identity registers (EIRs), to effectively block the use of these devices in the public land mobile network. Therefore, MNOs may play an important role in the effective implementation of RUPF.
+
+#### **I.1.8 Financial institutions**
+
+Nowadays, mobile devices carry a lot of valuable assets such as personal data and access to financial services, including online payment and Internet banking. Taking that into account, the RUPF information about stolen devices may be used by financial institutions so that anti-fraud measures can be taken in a timely manner (e.g., temporary limitation for mobile transactions). The information could be accessed directly from the RUPF or provided by LEA, depending on the national strategy. Financial institutions may also consider sourcing an authentic stolen device list from the RUPF in their fraud management systems to block stolen or tampered ICT devices from making financial transactions. Additionally, further restrictions to a consumer's account may be implemented at the discretion of their financial institution, because of the potential loss of personal data. Such collaborative steps across different sectors will enable the effective mitigation of negative impacts of stolen or tampered ICT devices on consumers.
+
+### **I.2 Impact of counterfeit and tampered devices on consumers**
+
+The ecosystem of counterfeit and tampered mobile telecommunication/ICT devices is focused on exploiting susceptible consumers. Due to lack of consumer awareness and ignorance combined with the cheaper cost of counterfeit and tampered devices, consumers are enticed to buy them. The following are possible negative impacts consumers may suffer when using counterfeit and tampered telecommunication/ICT devices:
+
+- i) **Lack of technical support and warranty:** Counterfeit and tampered mobile telecommunication/ICT devices are generally bought and sold through unauthorized channels bypassing applicable tax and without proper invoicing and therefore warranty and after-sales support are not assured.
+- ii) **Absence of recourse in case of fault:** In absence of a proof of purchase and invoice, consumers cannot avail themselves of any recourse for redressing their grievance and enforcing their rights.
+- iii) **Compromise on quality of service and quality of experience (QoE):** The quality of telecom services and consumer experience depend not only on the performance of the MNO's network but also on the quality and performance of the user device. Thus, consumers may be deprived of expected QoE when using a counterfeit or tampered mobile telecommunication/ICT device in spite of spending money on the device and the and MNO service subscription.
+- iv) **Consumer safety:** Counterfeit or tampered ICT devices may not be subjected to routine safety tests and compliance with national standards in the way that genuine OEM brands are as they do not operate within regulatory manufacturing framework. Non-enforcement of safety standards may lead to safety risks to the end consumers.
+- v) **Consumer security and privacy:** Counterfeit mobile telecommunication/ICT device manufacturers do not have any incentive in development of quality software and applications. It is likely that the operating system or preloaded bundled applications may be used for data collection that may compromise consumer data security and may result in a breach of consumer privacy. A breach of data security may also have other financial or non-financial implications for end consumers.
+
+### I.3 Measures for mitigation of adverse impact on consumers
+
+Considering the number of possible risks emanating from the use of counterfeit or tampered mobile telecommunication/ICT devices, it is imperative for Member States to take steps to mitigate or minimize adverse impacts of end consumers. The following are some key measures to minimize the adverse impact on end consumers of counterfeit or tampered mobile telecommunication/ICT devices.
+
+- i) **Consumer awareness:** The ecosystem of counterfeit and tampered mobile telecommunication/ICT devices is centred on the consumer to exploit them monetarily. The use of such devices may also result in costs associated with compromise of data and privacy. Consumers are attracted towards such devices due to a perceived cost advantage vis-à-vis genuine devices with similar features. However, due to lack of awareness among consumers of other possible risks and costs associated with use of these devices, the proliferation of counterfeit and tampered devices is increasing day by day.
+
+Therefore, the first and most important need is to make consumers aware of possible risks and costs associated with the use of counterfeit devices. The proliferation of counterfeit and tampered mobile devices not only has risks for consumers but also has cost implications to Member States in the form of foregone taxes, for OEMs as an opportunity cost due to market share captured by such devices and for MNOs in the form of impact on consumer experience and quality of service.
+
+Thus, it is in the interest of Member States, OEMs and MNOs to invest in consumer awareness and education campaigns through their respective channels and touch points. For example, MNOs can send awareness message to their customers periodically, display posters at their outlets or include this aspect in their customer welcome kit. Similarly, OEMs may run awareness campaigns through social and electronic media including their own or partner outlets. Member States may also run awareness and education campaigns through their consumer protection departments. Considering the fact that the target consumer of such devices may belong to low- and middle-income groups with an average level of education,
+
+awareness campaigns should be simple and easy to understand without complicated technical details. Such awareness campaigns may also include simple checks and questions to be asked while purchasing any mobile telecommunication/ICT device. The unified technology platform per the RUPF framework can become an important tool for consumer empowerment and education as well as a collaboration platform for all stakeholders.
+
+- ii) **Enabling the regulatory framework:** While consumer education and awareness is the most important measure for the mitigation of adverse impact on consumers, the enabling regulatory framework is equally important to deter the counterfeiters and enable LEAs to act swiftly against the traffickers and counterfeiter ecosystem. It should empower the LEAs by enabling criminal provisions and use of technical platforms like RUPF.
+- iii) **Collaboration among stakeholders:** To mitigate the adverse impact of counterfeit or tampered mobile telecommunication/ICT devices on consumers, close collaboration among LEAs, customs and excise, OEMs and Member States will be required to take effective measures for arresting the trend of an increasing rate of proliferation of such devices. Considering the role to be played by multiple stakeholders for taking effective measures, one-to-one collaboration may not be sufficient as coordinated actions will be required to break the fragmented supply chains operated by traffickers and manufacturers of counterfeit devices. Therefore, technology platforms can effectively be used for effective collaboration.
+- iv) **Implementation of a comprehensive technology platform based on the RUPF:** To enable consumer empowerment through tools and awareness, collaboration amongst key stakeholders such as LEAs, customs and excise, OEMs and MNOs, and for timely action against counterfeiters, RUPF based technology solution with an enabling regulatory framework can play a pivotal role. The unified technology platform enables a timely exchange of information required to trigger countermeasures upon the detection or reporting of counterfeit devices at different touch points in the ecosystem. Consumer queries and logs, along with other data available on the platform, can be used for analytics to discover trends and patterns for taking preventive measures against the proliferation of counterfeit devices. The RUPF is likely to increase the cost and risks associated with the manufacturing and trafficking of counterfeit devices, which will reduce the price advantage currently enjoyed by counterfeit mobile telecommunication/ICT devices over genuine ones. Such a reduction in the price gap between genuine and counterfeit devices may result in the increased use and adoption of genuine mobile telecommunication/ICT devices.
+- v) **Development of standards for unique, reliable and verifiable device identifiers:** Currently, IMEI seems to be only unique identifier in use that is part of any standard and used to distinguish between genuine and counterfeit ICT device. This unique identifier is used by the network and visible on the device and thus can be copied and used as a replicated unique identifier. The counterfeit mobile telecommunication/ICT devices are so close to genuine ones in look and features that it is not possible to identify a genuine device if they have a replicated unique identifier. Only a unique and verifiable identifier can play an effective role in the detection of counterfeit devices to keep them out of mobile networks. Therefore, there is an urgent need to evolve standards and mechanisms for adoption in the mobile telecommunication/ICT device ecosystem to make them unique and verifiable to consumers and mitigate the adverse impact on them.

+# FOREWORD
+
+The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.512 was revised by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 7th of February 1995.
+
+# --- NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+# SUMMARY
+
+This Recommendation describes the subscriber side interface characteristics of digital exchanges. It applies to digital local and combined exchanges for telephony in Integrated Digital Networks (IDN) and to local and combined exchanges in an Integrated Services Digital Network (ISDN), and also to mixed (analogue/digital) networks.
+
+This Recommendation is part of the Q.510-Series of Recommendations which defines the interface functions for digital exchanges in Integrated Digital Networks (IDN), mixed analogue/digital networks, 64 kbit/s-based Integrated Services Digital Network (ISDN).
+
+# BACKGROUND
+
+## Preamble to the Q.500-Series of Recommendations
+
+In 1980, CCITT Study Group XI published the first series of Q.500 Recommendations related to “Digital transit exchanges for national and international applications”.
+
+In 1984, CCITT Study Group XI approved two sets of Recommendations on digital exchanges:
+
+- “Digital transit exchanges in integrated digital networks and mixed analogue/digital networks” – Q.500-Series of Recommendations; and
+- “Digital local and combined exchanges” – Q.510-Series of Recommendations.
+
+In 1988, CCITT Study Group XI combined the Series Q.500 and Q.510 Recommendations into a single set applicable to digital local, combined, transit and international exchanges in Integrated Digital Networks (IDN) and mixed analogue-digital networks, and also to local, combined, transit and international exchanges in an Integrated Services Digital Network (ISDN).
+
+In 1994, ITU-T Study Group 11 revised the Q.500-Series of Recommendations in order to include a new exchange interface for subscriber access – the V<sub>5</sub> interface (i.e. the V<sub>5.1</sub> interface). The V<sub>3</sub> interface is to the case of an ISDN primary rate access and the case that this interface is used not structured according to the ISDN principles is considered as not subject to ITU-T Recommendations. The V<sub>4</sub> interface is marked as not subject to ITU-T Recommendations; reference should be made to interface V<sub>5.1</sub> which covers static multiplexed ISDN basic accesses. The V<sub>4</sub> interface was a digital interface used to connect a digital access link which includes a static multiplexer supporting several basic access digital sections. For this interface, the specification (i.e. CV<sub>1</sub> channel structure) was not completed.
+
+ITU-T will continue to further develop and complete these Recommendations in areas where there are unresolved issues and develop additional Recommendations on digital exchanges in the Q.500-Series and other series in the future.
+
+The structure for the Q.500-Series of digital switching Recommendations is provided in Recommendation Q.500.

+# DIGITAL EXCHANGE INTERFACES FOR SUBSCRIBER ACCESS
+
+(Melbourne, 1988; revised in 1994)
+
+## 1 Scope
+
+It applies to digital local and combined exchanges for telephony in Integrated Digital Networks (IDN) and to local and combined exchanges in an Integrated Services Digital Network (ISDN), and also to mixed (analogue/digital) networks. The field of application of this Recommendation is more fully defined in Recommendation Q.500 [B6].
+
+Exchange interfaces for subscriber access that have been considered are described, and illustrated in Figure 1 and Table 1, but they are not intended to specify every interface. Other interfaces are for further study.
+
+This Recommendation is not intended to define any transmission system, network or subscriber equipment in or connected to, a digital exchange via these interfaces. Therefore only the characteristics of the interfaces are described.
+

+
+## 3 Terms and definitions
+
+For the purposes of this Recommendation, the following definitions apply:
+
+**3.1 digital section:** A digital section is defined as the whole of the means of digital transmission of a digital signal of specified rate between two consecutive reference points. A digital link comprises one or more digital sections and may include either a multiplexer or concentrator, but not switching.
+
+**3.2 access digital section:** The functional requirements to transmit the information from/to the user-network interface and to transmit, multiplex, demultiplex and process information required for operation and maintenance from/to the associated V-reference point related to that particular user-network interface. This excludes the extraction, concentration and multiplexing/demultiplexing of channels with hierarchies other than the one being concerned (as these are considered by the V-reference point).
+
+In addition, this Recommendation uses terms defined in Recommendations G.962 [6], G.963 [7], G.964 [8], G.965 [9] and Q.9 [B5].
+
+In this Recommendation the term “exchange” or “local exchange” is used for conciseness to indicate both a (digital) local exchange and a (digital) combined exchange. A (digital) combined exchange is one which includes both local exchange and transit/toll exchange functions.

+## 5 Characteristics of digital interfaces for subscriber access
+
+### 5.1 General
+
+Digital interfaces for subscriber access are defined at the V-reference point which is the boundary between the Exchange Termination (ET) and the digital access section or link. These interfaces are designated interface V and are defined to allow flexibility of implementation for different exchange and transmission equipment realizations. However, a physical interface will not be specified for all subscriber access types identified (see Figure 1).
+
+As an objective, the characteristics of digital interfaces on the subscriber side of the exchange should be aligned with the characteristics of ISDN user/network access structures (see Recommendation I.411 [B1]).
+
+However, in many countries, digital access arrangements not structured according to ISDN principles are used, e.g. to ensure compatibility with existing networks and services and it is expected that these arrangements will continue to be used for several years. These types of interfaces not structured according to the ISDN principles are not subject to ITU-T Recommendations.
+
+### 5.2 Interface V<sub>1</sub>
+
+#### 5.2.1 General
+
+Interface V<sub>1</sub> may be used at the V<sub>1</sub> reference point to connect to an ISDN basic access digital section for the provision of a single basic access. The characteristics of the basic access digital section are defined in Recommendation G.960 [4] and the characteristics and parameters of a digital transmission system which may form part of the digital section for the ISDN basic rate access are given in Recommendation G.961 [5].
+
+#### 5.2.2 Functional characteristics
+
+The functional description is illustrated in Figure 2 and the following functional requirements are defined:
+
+- 1) *(2B + D) channels*  
+To provide the bidirectional transmission capability for two B-channels and one 16 kbit/s D-channel as described in Recommendation I.412 [B2].
+- 2) *Bit timing*  
+To provide bit (signal element) timing to enable the digital section to recover information from the aggregate bit stream.
+

+### 5.5 Interface V<sub>4</sub>
+
+This interface is not considered to be a matter for ITU-T Recommendations.
+
+NOTE – See information provided in “Background”.
+
+### 5.6 Interface V<sub>5</sub>
+
+#### 5.6.1 General
+
+Interface V<sub>5</sub> is a digital interface (based on 2048 kbit/s) between an Access Network (AN) and the Local Exchange for the support of the following access types:
+
+- analogue telephone access;
+- ISDN basic access with a line transmission system conforming to Recommendation G.960 [4] for the case with an NT1 separate from the AN;
+- ISDN basic access with a user network interface according to Recommendation I.430 [B3] at the user side of the AN (i.e. the interface at the T reference point);
+- ISDN primary rate access with a line transmission system conforming to Recommendation G.962 [6] for the case with an NT1 separate from the AN (V<sub>5.2</sub> interface only);
+- ISDN primary rate access with a user network interface according to Recommendation I.431 [B4] at the user side of the AN (i.e. the interface at the T reference point) (V<sub>5.2</sub> interface only);
+- other analogue or digital accesses for semi-permanent connections without associated outband signalling information.
+
+These access types are supported by interface V<sub>5</sub> using flexible information channel (bearer channel) allocation with (for V<sub>5.2</sub> interface as specified in Recommendation G.965 [9]) or without (for V<sub>5.1</sub> interface as specified in Recommendation G.964 [8]) concentration capability within the AN.
+
+The AN is defined as a system implemented between the Local Exchange and the user, replacing part or the whole of the local line distribution network. The functions associated with the V<sub>5</sub> interface of an AN can be configured and operated flexibly via a management Q interface. The detailed specification of the Q<sub>3</sub> interface specifications for the V<sub>5</sub> environment are contained in the Q.570-Series of Recommendations. The AN may consist of multiplexing, cross connect and transmission functions.
+
+The V<sub>5</sub> interface may be implemented as a V<sub>5.1</sub> or a V<sub>5.2</sub> interface supporting different access types and providing different bearer channel handling capabilities as given above. The V<sub>5.1</sub> interface consists of a single 2048 kbit/s interface while the V<sub>5.2</sub> interface can be a multiple of 2048 kbit/s interface links with a maximum number of 16 interface links.
+
+#### 5.6.2 Functional characteristics
+
+The functional and procedural requirements of the interface shall conform to Recommendation G.704 [2] and G.706 [3], 2048 kbit/s case. The CRC-4 (CRC) procedure specified in Recommendations G.704 [2] and G.706 [3] shall be applied including the CRC error reporting using bit E in the CRC-multiframe.
+
+The functional description is illustrated in Figure 3. The following functional requirements are defined:
+
+- *Bearer channels* – To provide the bidirectional transmission capability for allocated B-channels from basic access user ports or PCM encoded 64 kbit/s channels from PSTN user ports.
+- *ISDN D-channel information* – To provide the bidirectional transmission capability for D-channel information from basic access user ports (including Ds-, p- and f-type data).
+- *PSTN signalling information* – To provide the bidirectional transmission capability for signalling information of PSTN user ports.
+
+- *Control of user ports* – To provide the bidirectional transmission capability to carry the status and control of each individual user port.
+- *Control of the 2048 kbit/s link* – Frame alignment, multiframe alignment, alarm indication and CRC information of the 2048 kbit/s.
+- *Control of layer 2 links* – To provide bidirectional communication capabilities to carry the various protocols.
+- *Control for the support of common functions* – To provide synchronized application of provisioning data and restart capability.
+- *Timing* – To provide the necessary timing information for bit transmission, octet identification and frame synchronization.
+- *Control of 2048 kbit/s link related procedures* – To provide link identification and link blocking and unblocking capability ( $V_{5.2}$  only).
+- *Control of bearer channel connections* – To provide on-demand bearer channel connection allocation and deallocation for the concentration function ( $V_{5.2}$  only).
+- *Communication channel protection* – To control protection switching for communication channels affected by 2048 kbit/s link failure ( $V_{5.2}$  only).

+#### **5.6.3 Electrical characteristics**
+
+The V<sub>5.1</sub> interface consists of a single 2048 kbit/s interface as defined in Recommendation G.703 [1].
+
+The V<sub>5.2</sub> interface may consist of a maximum of 16 times 2 048 kbit/s interface links as defined in Recommendation G.703 [1].
+
+The electrical and physical characteristics of the interface for each interface link shall conform to Recommendation G.703 [1], 2048 kbit/s case.
+
+#### **5.6.4 Channel types, channel allocation and signalling**
+
+The information provided below is an excerpt of the detailed V<sub>5</sub> interface specifications as contained in Recommendations G.964 [8] and G.965 [9].
+
+##### **5.6.4.1 Channel types**
+
+The V<sub>5.1</sub> interface or any link of the V<sub>5.2</sub> interface shall be structured according to Recommendations G.704 [2] and G.706 [3]. Timeslots 1 to 31 shall be used for channel types allocated by provisioning:
+
+- timeslots which carry ISDN and PSTN bearer channels;
+- communication channels which carry ISDN D-channel information, PSTN signalling information and control information;
+- communication channels which carry information for the link control, the bearer connection control and the link protection (V<sub>5.2</sub> only).
+
+##### **5.6.4.2 Channel allocation**
+
+There may be 1, 2 or 3 communication channels provisioned in the V<sub>5.1</sub> interface. Only timeslots 16, 15 and 31 shall be assigned for communication channels. All timeslots not allocated for a communication channel may be allocated to bearer channels by provisioning.
+
+There may be 0, 1, 2 or 3 communication channels provisioned for any link of a V<sub>5.2</sub> interface. Only timeslots 16, 15 and 31 shall be assigned for communication channels. All timeslots not allocated for a communication channel may be allocated to bearer channels under control of the bearer channel connection protocol.
+
+##### **5.6.4.3 Signalling**
+
+Signalling information for PSTN user ports are carried by a PSTN signalling protocol allocated to one of the provisioned communication channels.
+
+Signalling information for ISDN user ports, as well as p-type and f-type data, are frame relayed into the provisioned communication channels.
+
+Information for the control of user ports, links, bearer channel connections and protection of communication channels are carried by the relevant protocols in the assigned communication channels.
+
+The related Recommendations for the protocols are given in Recommendations G.964 [8] and G.965 [9].
+
+## **6 Characteristics of analogue interfaces for subscriber access**
+
+### **6.1 Interface Z**
+
+Interface Z is a generic analogue interface defined at the exchange side of an analogue subscriber line used to connect subscriber equipment (e.g., single telephone set or PABX).
+
+It is recognized that the characteristics of analogue interfaces (generally designated Z-interface) vary considerably from country to country and therefore it is not intended that those interfaces be the subject of ITU-T Recommendations beyond those aspects covered in Recommendations Q.551 [B7] and Q.552 [B8].

+## **ITU-T Recommendation Q.552**
+
+# **Transmission characteristics at 2-wire analogue interfaces of digital exchanges**
+
+## **Summary**
+
+This Recommendation provides characteristics for 2-wire analogue interfaces, input and output connections with 2-wire analogue interfaces and half-connections with 2-wire analogue interfaces in accordance with definitions given in ITU-T Q.551.
+
+This Recommendation is valid for equipment that may terminate an international long-distance connection via 4-wire circuits interconnected by 4-wire exchange. It also includes, in a separate category, characteristics for interfaces which cannot terminate an international connection and are therefore entirely national in application.
+
+## **Source**
+
+ITU-T Recommendation Q.552 was prepared by ITU-T Study Group 15 (2001-2004) and approved under the WTSA Resolution 1 procedure on 29 November 2001.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# Transmission characteristics at 2-wire analogue interfaces of digital exchanges
+
+# 1 General
+
+This Recommendation provides characteristics for:
+
+- 2-wire analogue interfaces (Type C<sub>2</sub> and Z);
+- input and output connections with 2-wire analogue interfaces; and
+- half-connections with 2-wire analogue interfaces;
+
+in accordance with definitions given in ITU-T Q.551 particularly in Figure 1/Q.551.
+
+The characteristics of the input and output connections of a given interface are not necessarily the same. The characteristics of half-connections are not necessarily identical for different types of interfaces.
+
+This Recommendation is valid for equipment that may terminate an international long-distance connection via 4-wire circuits interconnected by 4-wire exchanges. It also includes, in a separate category, characteristics for interfaces which cannot terminate an international connection and are therefore entirely national in application.
+
+## 2 Characteristics of interfaces
+
+NOTE – For measuring 2-wire analogue interface conditions it is necessary to apply a quiet code, i.e. a PCM signal corresponding to decoder output value 0 ( $\mu$ -law) or output value 1 (A-law), with the sign bit in a fixed state, to the exchange test point T<sub>i</sub>, when no test signal is stipulated.
+
+### 2.1 Characteristics of interface C<sub>2</sub>
+
+The recommended values of interfaces C<sub>2</sub> are valid for digital exchanges including PABXs with transit functions and routing capabilities for originating and terminating traffic. Depending on the type of traffic to be handled, two different sets of relative levels are required. This suggests subdivision into C<sub>21</sub> and C<sub>22</sub> interface specifications. The interface C<sub>21</sub> provides the termination of outgoing and incoming international long-distance connections and possible national connections, with the exchange acting as transit switch. The interface C<sub>22</sub> provides for the connection of a 2-wire trunk line. A typical example is the interconnection of a Z interface with a C<sub>22</sub> interface in a local exchange for routing through the 2-wire analogue trunk network. A C<sub>22</sub> interface cannot be part of the international 4-wire chain (see Figure 2/Q.551).
+
+#### 2.1.1 Exchange impedance
+
+##### 2.1.1.1 Nominal value
+
+Nominal values of exchange impedance should be defined depending on national conditions. The definition shall include a test network for the exchange impedance. Network operators may want to adopt different test networks corresponding to the cable types used (e.g. unloaded and loaded).
+
+##### 2.1.1.2 Return loss
+
+The return loss of the impedance presented by a C<sub>2</sub> interface against the test network for the exchange impedance should comply with the limits given in Figure 1.
+
+![Figure 1/Q.552: Minimum value of return loss against the test network for the exchange impedance at a 2-wire interface. The graph shows Return loss (dB) on the y-axis (14 to 18) versus Frequency (f) in Hz on the x-axis (300 to 3400). The return loss is 14 dB at 300 Hz, rises to 18 dB at 500 Hz, stays at 18 dB until 2000 Hz, and then falls back to 14 dB at 3400 Hz. A shaded region indicates the minimum required return loss.](c3c305cefbac2e7b13be34ab87054d1e_img.jpg)

+| 500                | 18               |
+| 2000               | 18               |
+| 3400               | 14               |

+
+#### 2.1.2 Impedance unbalance about earth
+
+The Longitudinal Conversion Loss (LCL) at the interface, defined in 4.1.3/G.117, should exceed the minimum values of Figure 2 with the equipment under test in the normal talking state, in accordance with ITU-T K.10.
+
+NOTE 1 – A network operator may adopt other values and in some cases a wider bandwidth, depending on actual conditions in its telephone network.
+
+NOTE 2 – A limit may also be required for the Transverse Conversion Loss (TCL), as defined in 4.1.2/G.117, if the exchange termination is not reciprocal with respect to the transverse and longitudinal paths. A suitable limit would be 40 dB to ensure an adequate near-end crosstalk attenuation between interfaces.

+
+##### Test method
+
+Longitudinal conversion loss at the  $C_2$  equipment port should be measured in accordance with the principles given in 4.1/O.9. Figure 3 shows an example of the basic measuring arrangement for digital exchanges. Arrangements containing two resistors each of value  $R/2$  may also be used (see 5.1/O.9).
+
+Measurements of the longitudinal and transverse voltages should preferably be done with a frequency-selective level meter.

+
+#### 2.1.3 Relative levels
+
+##### 2.1.3.1 Nominal levels
+
+###### 2.1.3.1.1 Interface C<sub>21</sub>
+
+C<sub>21</sub> interfaces should meet the recommended values for Z interfaces in 2.2.3.1 if no loss compensation comparable to 2.2.3.3 is provided.
+
+###### 2.1.3.1.2 Interface C<sub>22</sub>
+
+To adjust the transmission loss of a digital transmission section to the values of national transmission planning for local or national traffic, depending on the relative levels given in 2.1.3.1.1 and 2.2.3.1, the following ranges encompass the requirements for C<sub>22</sub> interfaces of a large number of network operators:
+
+- input level:  $L_i = +3.0$  to  $-7.0$  dBr in 0.5 dB steps;
+- output level:  $L_o = +1.0$  to  $-8.0$  dBr in 0.5 dB steps.
+
+In order to compensate loss on long toll or junction lines, a network operator may, to satisfy local conditions, choose values of relative levels derived from the basic values as follows:
+
+$$L'_i = L_i + x \text{ dB}$$
+
+$$L'_o = L_o - x \text{ dB}$$
+
+where  $x$  should take a negative value. The value of  $x$  is in national competence. Such compensation of loss requires careful selection and application of balance networks.
+
+It has been recognized that it is not necessary for a particular design of equipment to be capable of operating over the entire level range.
+
+##### 2.1.3.2 Tolerances of relative levels
+
+The difference between the actual relative level and the nominal relative level should lie within the following values:
+
+- input relative level: –0.3 to +0.7 dB;
+- output relative level: –0.7 to +0.3 dB.
+
+These differences may arise, for example, from design tolerances, cabling between analogue ports and the (DF), and adjustment increments.
+
+NOTE – Level adjustment procedures are given in clause 3/G.712.
+
+### 2.2 Characteristics of interface Z
+
+The recommended values of interface Z are valid for digital local exchanges, PABXs and digital remote units. For PABXs, see 2.1.1/Q.551.
+
+#### 2.2.1 Exchange impedance
+
+Guidance for network operators can be found in Appendix I.
+
+##### 2.2.1.1 Nominal value
+
+The principal criterion governing the choice of the nominal value of the exchange impedance is to ensure an adequate sidetone performance for telephone sets, particularly those operated on short lines. If this criterion is met, the impedance will also be suitable for subscriber lines fitted with voiceband modems.
+
+As a general rule a complex exchange impedance with a capacitive reactance is necessary to achieve satisfactory values of stability, echo and sidetone. For additional information, see ITU-T G.111 and ITU-T G.121.
+
+The use of the preferred configuration below will minimize the diversity of types of exchange impedances. At present no unique component values can be recommended. However, to provide guidance for network operators, examples of nominal values chosen by some network operators are given in Table 1.

+
+NOTE 1 – The test network and the component values represent a configuration that exhibits the required exchange impedance. It need not necessarily correspond to any actual network provided in the exchange interface.
+
+**Table 1/Q.552 – Test networks for exchange impedances being considered**
+
+NOTE 2 – The range of component values reflects the fact that there are substantial differences in the sensitivity and sidetone performance of the various telephone instruments throughout the world. In general, the combination of short lines and sensitive telephone sets might be rather common in the future due to increased use of remote concentration. In order to control sidetone performance, network operators need to take into account telephone set parameters. Not only should the parameters of existing telephone sets be considered but also the parameters that may be desirable in the future to allow improvement in sidetone performance to be achieved.
+
+NOTE 3 – It may be necessary to group the subscriber lines of a particular exchange into classes, each requiring a different exchange impedance of the Z interface.
+
+##### 2.2.1.2 Return loss
+
+Tolerances are needed for values of exchange impedance. For this purpose, the return loss of the impedance presented by a 2-wire interface against the test network for the exchange impedance should comply with limits which depend on the particular conditions of the subscriber network considered. These are given in the template of Figure 1.
+
+Some network operators may want to specify higher values. Examples of limit values for the return loss, currently accepted by some network operators, are given in Table 2 for guidance.
+

+#### 2.2.2 Impedance unbalance about earth
+
+The Longitudinal Conversion Loss (LCL) at the equipment post of the Z interface should meet the values given in 2.1.2 and Figure 2, measured in accordance with the test method given in Figure 3.
+
+#### 2.2.3 Relative levels
+
+Operation of the Z interface in the ranges of relative levels given below is recommended when the interface terminates an entirely 4-wire international long-distance connection. Pairs of input and output levels can be chosen for internal, local, or national long-distance traffic in a wider range if these connections can be discriminated from international ones for correct level switching. If digital pads are used, the additional distortion must be considered (see Table 1/G.113).
+
+In assigning the relative levels for international long-distance connections to the interface, it should be noted that:
+
+- The limiting of "difference in transmission loss between the two directions of transmission" in 2.2/G.121 must be taken into account. For the national extension, this is the value "loss (t-b)-loss(a-t)". (See the text in the cited Recommendation for guidance.) This difference is
+
+limited to  $\pm 4$  dB. However, to allow for additional asymmetry of loss in the rest of the national network, only part of this difference can be used by the digital exchange.
+
+- If within the ranges of  $L_i$  and  $L_o$  given under 2.2.3.1.1 and 2.2.3.1.2, the values are chosen such that  $L_i - L_o \geq 6$  dB and if adequate balance networks are used (e.g. 3.1.8 and Figure 10), the requirements of clause 6/G.121 (Incorporation of PCM digital processes in national extensions) as well as for ITU-T G.122 (Stability and echo loss) will be satisfied.
+
+##### 2.2.3.1 Nominal levels
+
+###### 2.2.3.1.1 Input relative level
+
+According to Annex C/G.121 (columns 3, 5 and 7 of Table C.1/G.121), the following range of input relative level for all types of connections (internal, local, national and international) encompasses the requirements of a large number of network operators:
+
+$$L_i = 0 \text{ to } +2.0 \text{ dBr}$$
+
+NOTE – Clause 3.6/G.101 and clause 3/G.121 indicate that if the minimum nominal Send Loudness Rating (SLR) of the local system under the same conditions is not less than  $+2$  dB, then the peak power of the speech will be suitably controlled. It follows that, for instance, the value  $L_i = 0$  dBr (lower limit of the range for  $L_i$ ) is suited to a send loudness rating  $\geq +2$  dB.
+
+###### 2.2.3.1.2 Output relative level
+
+According to Annex C/G.121 (column 6 of Table C.1/G.121), the following range of output relative level for international long-distance connections encompasses the requirements of a large number of network operators:
+
+$$L_o = -5.0 \text{ to } -8.0 \text{ dBr}$$
+
+The chosen value may be used for connections entirely within a national network as well.
+
+The nominal output relative levels for local or national connections can take other values in accordance with national transmission planning. According to Annex C/G.121 (columns 2 and 4 of Table C.1/G.121), the following range encompasses the requirements of a large number of network operators:
+
+$$L_o = 0 \text{ to } -8.0 \text{ dBr}$$
+
+It has been recognized that it is not necessary for a particular design of equipment to be capable of operating over the entire range.
+
+##### 2.2.3.2 Tolerances of relative levels
+
+The difference between the actual relative level and the nominal relative level should lie within the following limits:
+
+- input relative level:  $-0.3$  to  $+0.7$  dB;
+- output relative level:  $-0.7$  to  $+0.3$  dB.
+
+These differences may arise, for example, from design tolerances, cabling (between analogue ports and the DF) and adjustment increments. Short-term variation of loss with time as discussed in 3.1.1.3 is not included.
+
+NOTE – Procedures for adjusting relative level are given in clause 3/G.712.
+
+##### 2.2.3.3 Consideration of short and long subscriber lines
+
+In order to compensate for the loss of short or long subscriber lines, a network operator may choose values of the relative levels derived from the basic values as follows:
+
+$$L'_i = L_i + x \text{ dB}$$
+
+$$L'_o = L_o - x \text{ dB}$$
+
+The value of  $x$  is within national competence (e.g.  $x = 3 \text{ dB}$  for short subscriber lines).
+
+The use of values of  $x < 0$  requires careful selection of balance networks; values of  $x < -3 \text{ dB}$  are not recommended.
+
+## 3 Characteristics of half-connections
+
+For interfaces  $C_2$ , this Recommendation is valid for digital local and transit exchanges and for  $C_{21}$  interfaces of PABXs connected to the digital local exchange by a digital transmission system.
+
+For interface  $Z$ , this Recommendation is valid for digital local and combined local/transit exchanges, for PABXs and for digital remote units, each connected to the digital local exchange by a digital transmission system. For further information concerning PABXs, see 2.1.1/Q.551.
+
+NOTE – In measuring an input connection it is necessary to apply a quiet code, i.e. a PCM signal corresponding to decoder output value 0 ( $\mu$ -law) or output value 1 (A-law) with the sign bit in a fixed state to the exchange test point  $T_i$ . (See 1.2.3.1/Q.551.)
+
+### 3.1 Characteristics common to all 2-wire analogue interfaces
+
+#### 3.1.1 Transmission loss
+
+##### 3.1.1.1 Nominal value
+
+The nominal transmission loss according to 1.2.4.1/Q.551 is defined in 3.2.1 and 3.3.1 for input and output connections of half-connections with a 2-wire analogue interface.
+
+##### 3.1.1.2 Tolerances of transmission loss
+
+The difference between the actual transmission loss and the nominal transmission loss of an input or output connection, according to 2.1.3.2 and 2.2.3.2 should lie within the following range:
+
+$$-0.3 \text{ to } +0.7 \text{ dB}$$
+
+These differences may arise, for example, from design tolerances, cabling (between analogue interfaces and the DF) and adjustment increments. Short-term variation of loss with time as discussed in 3.1.1.3 is not included.
+
+##### 3.1.1.3 Short-term variation of loss with time
+
+When a sine wave test signal at the reference frequency of 1020 Hz and at a level of  $-10 \text{ dBm}0$  is applied to the 2-wire analogue interface of any input connection, or a digitally simulated sine wave signal of the same characteristic is applied to the exchange test point  $T_i$  of any output connection, the level at the corresponding exchange test point  $T_o$  and the 2-wire analogue interface respectively should not vary by more than  $\pm 0.2 \text{ dB}$  during any 10-minute interval of typical operation under the steady state condition of permitted variations in the power supply voltage and temperature.
+
+##### 3.1.1.4 Variation of gain with input level
+
+With a sine wave test signal at the reference frequency 1020 Hz and at a level between  $-55 \text{ dBm}0$  and  $+3 \text{ dBm}0$  applied to the 2-wire analogue interface of any input connection, or with a digitally simulated sine wave signal of the same characteristic applied to the exchange test point  $T_i$  of any output connection, the gain variation of that connection, relative to the gain at an input level of  $-10 \text{ dBm}0$ , should lie within the limits given in Figure 4.
+
+The measurement should be made with a frequency-selective level meter to reduce the effect of the exchange noise. This requires a sinusoidal test signal.

+
+For crosstalk measurements, auxiliary signals are injected as indicated in Figures 7 and 8. These signals are:
+
+- the quiet code (see 1.2.3.1/Q.551);
+- a low-level activating signal, e.g. a sine wave at a level in the range from  $-33$  to  $-40$  dBm0. Care must be taken in the choice of frequency and the filtering characteristics of the measuring apparatus in order that the activating signal does not significantly affect the accuracy of the crosstalk measurement.

+With a sine wave test signal at the reference frequency of 1020 Hz (see ITU-T O.132) applied to the 2-wire interface of an input connection, or with a digitally simulated sine wave signal of the same characteristic applied to the exchange test point  $T_i$  of an output connection, the signal-to-total-distortion ratio, measured at the corresponding outputs of the half-connection with a proper noise weighting (see Table 1/O.41) should lie above the limits given in 3.2.3, Figures 12 and 13 for interface  $C_2$  and in 3.3.3, Figure 14 for interface  $Z$ .
+
+NOTE – The sinusoidal test signal is chosen to obtain results independent of the spectral content of the exchange noise.
+
+#### **3.1.6 Discrimination against out-of-band signals applied to the input interface**
+
+(Only applicable to input connections.)
+
+##### **3.1.6.1 Input signals above 4.6 kHz**
+
+With a sine-wave signal in the range from 4.6 kHz to 72 kHz applied to the 2-wire interface of an input connection at a level of  $-25$  dBm0, the level of any image frequency produced in the time slot corresponding to the input connection should be at least 25 dB below the level of the test signal. This value may need to be more stringent to meet the overall requirement.
+
+##### **3.1.6.2 Overall requirement**
+
+Under the most adverse conditions encountered in a national network, the half-connection should not contribute more than 100 pW0p of additional noise in the band 10 Hz to 4 kHz at the output of the input connection, as a result of the presence of out-of-band signals at the 2-wire interface of the input connection.
+
+#### **3.1.7 Spurious out-of-band signals received at the output interface**
+
+(Only applicable to an output connection.)
+
+##### **3.1.7.1 Level of individual components**
+
+With a digitally simulated sine wave signal in the frequency range 300 to 3400 Hz and at a level of 0 dBm0 applied to the exchange test point  $T_i$  of a half-connection, the level of spurious out-of-band image signals measured selectively at the 2-wire interface of the output connection should be lower than  $-25$  dBm0. This value may need to be more stringent to meet the overall requirement.
+
+##### **3.1.7.2 Overall requirement**
+
+Spurious out-of-band signals should not give rise to unacceptable interference in equipment connected to the digital exchange. In particular, the intelligible and unintelligible crosstalk in a connected FDM channel should not exceed a level of  $-65$  dBm0 as a consequence of spurious out-of-band signals at the half-connections.
+
+#### **3.1.8 Echo and stability**
+
+Terminal Balance Return Loss (TBRL) as defined in 3.1.8.1 is introduced in order to characterize the exchange performance required to comply with the network performance objective of ITU-T G.122 with respect to echo and stability. The TBRL of an interface is measured in the talking state as in an established connection through a digital exchange.
+
+The parameter "Stability Loss", as defined in ITU-T G.122, applies to the worst terminating conditions encountered at a 2-wire interface in normal operation.
+
+##### 3.1.8.1 Terminal Balance Return Loss (TBRL)
+
+The term TBRL is used to characterize an impedance balancing property of the 2-wire analogue interface.
+
+The expression for TBRL is:
+
+$$TBRL = 20 \log \frac{Z_o + Z_b}{2Z_o} \times \frac{Z_t + Z_o}{Z_t - Z_b}$$
+
+where:
+
+$Z_o$  is the exchange impedance of a 2-wire equipment port;
+
+$Z_b$  is the impedance of the balance network;
+
+$Z_t$  is the impedance of the balance test network presented at a 2-wire interface
+
+Some network operators have found that it is advantageous to choose  $Z_o = Z_b$  in order to optimize TBRL. In this case the expression is reduced to:
+
+$$TBRL = 20 \log \left| \frac{Z_t + Z_b}{Z_t + Z_o} \right|$$
+
+and the balance test network will be identical to the test network for the exchange impedance.
+
+The balance test network should be representative of the impedance conditions to be expected from a population of terminated lines connected to 2-wire interfaces, as determined by the national transmission planning.
+
+The TBRL is related to the loss  $a_{io}$  between the exchange test point  $T_i$  and  $T_o$  of a half-connection as follows:
+
+$$TBRL = a_{io} - (a_o + a_i)$$
+
+where  $a_o$  and  $a_i$  are the losses between the exchange test point  $T_i$  and the 2-wire interface and between the 2-wire interface and the exchange test point  $T_o$ , respectively.
+
+TBRL can thus be determined by measurement of  $a_{io}$  provided the sum  $(a_o + a_i)$  is known. This can be derived in several ways:
+
+- a)  $a_o$  and  $a_i$  are assigned their nominal values  $NL_o$  and  $NL_i$  as defined in 3.2.1 and 3.3.1. Then:
+
+$$TBRL = a_{io} - (NL_o + NL_i)$$
+
+- b)  $a_o$  and  $a_i$  are measured with the load matched to the exchange impedance as actual transmission loss  $AL_o$  and  $AL_i$  (see 3.1.1.2). Then:
+
+$$TBRL = a_{io} - (AL_o + AL_i)$$
+
+- c) the loss  $a_{io}$  is measured with the 2-wire equipment port open- and short-circuited, giving losses  $a'_{io}$  and  $a''_{io}$  respectively.
+
+$$TBRL = a_{io} - \frac{a'_{io} + a''_{io}}{2}$$
+
+Method b) provides the most accurate results.
+
+Using the arrangement of Figure 9 and sinusoidal test signals, the measured TBRL should exceed the limits shown in Figure 10.

+**Figure 11/Q.552 – Examples of test networks to be used by some network operators  
+(applicable to unloaded subscriber lines)**
+
+Figure 11 gives examples of balance test networks adopted by some network operators for unloaded subscriber lines. These examples may provide guidance for other network operators in order to minimize the diversity of types of test networks; see also Appendix I.
+
+NOTE – Some network operators may need to adopt several balance test networks to cover the various types of unloaded and loaded cables.
+
+##### 3.1.8.2 Stability loss
+
+The stability loss should be measured between the exchange test points  $T_i$  and  $T_o$  of a half-connection (see Figure 9) by terminating the 2-wire interface with stability test networks representing the "worst terminating condition encountered in normal operation". Some network operators may find that open- and short-circuit terminations are sufficiently representative of worst-case conditions. Other network operators may need to specify, for example, an inductive termination to represent the worst-case condition.
+
+Where the digital exchange is connected to the international chain using only 4-wire switching and transmission, the half-connection of the digital exchange may provide the total stability loss of the national extension. The value of Stability Loss (SL) that is required for a 2-wire interface is a matter of national control provided that the requirements of ITU-T G.122 are met. A SL value of at least 6 dB at all frequencies between 200 Hz and 3600 Hz will ensure that the G.122 requirements are met. However, SL values of between 6 dB and 0 dB will formally comply with the present requirements of G.122. One network operator has found that a value of 3 dB is satisfactory in its environment.
+
+NOTE – It is suggested that the half-connection of a digital PABX, or of a digital remote unit, when connected to the digital local exchange by a digital transmission system, should also meet the requirements of 3.1.8.
+
+### 3.2 Characteristics of interface $C_2$
+
+#### 3.2.1 Nominal value of transmission loss
+
+According to the relative levels defined in 2.1.3.1, the nominal transmission losses of input or output connections  $NL_i$  and  $NL_o$  of a half-connection with  $C_2$  interfaces are in the following ranges:  
+ $C_{21}$  interfaces
+
+$NL_i = 0$  to 2.0 dB for all types of connections
+
+$NL_o = 5.0$  to 8.0 dB for international connections  
+0 to 8.0 dB for local or national connections
+
+$C_{22}$  interfaces
+
+$$\left. \begin{array}{l} NL_i = -7.0 \text{ to } 3.0 \text{ dB} \\ NL_o = -1.0 \text{ to } 8.0 \text{ dB} \end{array} \right\} \text{ for all types of connections}$$
+
+It has been recognized that it is not necessary for a particular design of equipment to be capable of operating over the entire range of nominal transmission losses.
+
+If a loss compensation is applied the nominal loss  $NL_i$  and  $NL_o$  should be corrected by the value of  $x$  dB chosen in connection with 2.1.3.1.2 or 2.2.3.3.
+
+#### 3.2.2 Noise
+
+##### 3.2.2.1 Weighted noise
+
+For the calculation of noise, worst-case conditions at the  $C_2$  interface are assumed. The band limiting effect of the encoder on the noise has not been taken into account.
+
+###### 3.2.2.1.1 Output connection
+
+Two components of noise must be considered. One of these is the noise arising from the quiet decoder, the other comes from analogue sources, such as signalling equipment and the analogue circuit for impedance and level adaptation. The first component is limited to  $-70$  dBm0p or  $-75$  dBmp respectively in accordance with Table 7/G.712; the other component is limited to
+
+-67 dBm0p (200 pW0p) in accordance with Annex A/G.120, i.e.  $-(67 + 3)$  dBm0p = -70 dBm0p for one 2-wire analogue interface.
+
+This results in the maximum values for the overall weighted noise in the talking state at the  $C_2$  interface of a digital exchange:
+
+- equipment with signalling on separate wires:
+  - 70 dBm0p for output relative levels  $L_o \geq -5$  dBr;
+  - 75 dBmp for output relative levels  $L_o < -5$  dBr;
+- equipment with signalling on the speech wires:
+  - 67 dBm0p for output relative levels  $L_o \geq -5$  dBr;
+
+i.e. -72.5 dBmp and -73.2 dBmp respectively for output relative levels  $L_o = -6$  dBr and  $-8$  dBr.
+
+Values for other output relative levels cited in 2.1.3.1 can be calculated by using the formula given in 3.4.1/Q.551.
+
+###### 3.2.2.1.2 Input connection
+
+Two components of noise must be considered. One of these arises from the encoding process, the other from analogue sources, such as signalling equipment and the analogue circuit for impedance and level adaptation. The first component is limited to -67 dBm0p as idle channel noise in accordance with Table 7/G.712; the other component is limited to -67 dBm0p (200 pW0p) in accordance with Annex A/G.120, i.e.  $-(67 + 3)$  dBm0p = -70 dBm0p for one 2-wire analogue interface.
+
+The maximum values for the overall weighted noise in the talking state at the exchange test point  $T_o$  of a digital exchange should be not more than:
+
+- 67.0 dBm0p for equipment with signalling on separate wires;
+- 65.2 dBm0p for equipment with signalling on the speech wires.
+
+##### 3.2.2.2 Unweighted noise
+
+This noise will be more dependent on the noise from the power supply and on the rejection ratio.
+
+#### 3.2.3 Values of total distortion
+
+The total distortion including quantizing distortion of a half-connection with a  $C_2$  interface is measured in accordance with 3.1.5.
+
+The signal-to-total distortion ratio for a half-connection at interface  $C_2$  should lie above the limits shown in Figure 12 for equipment with signalling on separate wires, and in Figure 13 for equipment with signalling on the speech wires both measured in the talking state.

+
+### 3.3 Characteristics of interface Z
+
+#### 3.3.1 Nominal value of transmission loss
+
+According to the relative levels defined in 2.2.3.1, the nominal transmission losses of input or output connections  $NL_i$  and  $NL_o$  of a half-connection with Z interfaces are in the following ranges:
+
+$NL_i = 0$  to  $2.0$  dB for all types of connections
+
+$NL_o = 5.0$  to  $8.0$  dB for international connections
+
+$0$  to  $8.0$  dB for internal, local or national connections.
+
+If a compensation for the loss of short or long subscriber lines is applied, the nominal loss  $NL_i$  and  $NL_o$  should be corrected by the value of  $x$  dB chosen in connection with 2.2.3.3.
+
+#### 3.3.2 Noise
+
+##### 3.3.2.1 Weighted noise
+
+For the calculation of noise, worst-case conditions at the Z interface are assumed. The band limiting effect of the encoder on the noise has not been taken into account.
+
+###### 3.3.2.1.1 Output connection
+
+Two components of noise must be considered. One of these, namely noise arising from the decoding process, is dependent upon the output relative level. The other, for example power supply noise from the feeding bridge and circuit noise, is independent of the output relative level. The first component is limited to  $-70$  dBm0p in accordance with Table 7/G.712; the other component is limited to  $200$  pWp ( $-67$  dBmp) in accordance with Annex A/G.120. Possible sources of this latter component are the main DC power supply, auxiliary DC-DC converters and the circuit for 4-wire to 2-wire conversion with impedance and level adaptation.
+
+For an output relative level of  $L_o = -7.0$  dBr, the resulting total noise level for the output connection is:
+
+$$L_{TNo} \leq -66.6 \text{ dBmp}$$
+
+Values for other output relative levels cited in 2.2.3.1.2 can be calculated by using the formula given in 3.4.1/Q.551.
+
+###### 3.3.2.1.2 Input connection
+
+Two components of noise must be considered. One of these, namely noise arising from the encoding process is independent to the input relative level. The other, for example power supply noise from the feeding bridge and the circuit noise, is dependent upon the input relative level. The first component is limited to  $-67$  dBm0p as idle channel noise in accordance with Table 7/G.712; the other component is limited to  $200$  pWp ( $-67$  dBmp) in accordance with Annex A/G.120. For an input relative level of  $L_i = 0$  dBr the resulting total noise level for the input connection is:  $L_{TNi} = -64.0$  dBm0p.
+
+The total psophometric power allowed at the exchange test point  $T_o$  with an input relative level of  $L_i = 0$  dBr is:
+
+$$P_{TNi} = P_{AN} \cdot 10^{\frac{-L_i}{10}} + 10^{\frac{90+L_{TNi}}{10}} \text{ pWp}$$
+
+and the total noise level is:
+
+$$L_{TNi} = -64.0 \text{ dBm0p}$$
+
+Values for other input relative levels cited in 2.2.3.1.1 can be calculated by using the formula given in 3.4.1/Q.551.

+
+This noise will be more dependent on the noise from the power supply and on the rejection ratio.

+
+The total distortion including quantizing distortion on half-connections with Z interfaces is measured in accordance with 3.1.5.
+
+Resulting templates for the signal-to-total distortion ratio of input and output connections in a local exchange are shown in Figure 14 a) and 14 b) as an example where  $L_i = 0$  dBr and  $L_o = -7$  dBr respectively.
+

+## Impedance strategy in 2-wire networks
+
+## I.1 Introduction
+
+The aim of this appendix is to describe in more detail the methodologies which can be applied to determine termination impedances and balance networks. While termination impedance may affect sidetone on some telephones, echo which is controlled by the balance network is of much greater importance. Therefore, balance network selection is very critical no matter what termination impedance is selected. Additional information is also available in [1].
+
+In order to provide a network with good echo and sidetone performance, it is necessary to employ a certain impedance strategy in the 2-wire analogue parts of the network where the signals are transmitted simultaneously in both directions on the same pair of wires. It is of course necessary to separate the signals – transmit and receive – from each other at the ends of a 2-wire section and this is done by means of so-called hybrids which have in principle four ports (see Figure I.1):
+
+- the 2-wire port (2);
+- the 4-wire transmit port (T);
+- the 4-wire receive port (R);
+- the balance network port (B).
+
+![Diagram of a general hybrid. On the left, Port (2) is shown with an input impedance Z_T indicated by a right-pointing arrow and a balance impedance Z_2 indicated by a left-pointing arrow. On the right, there are three ports: Port (T) at the top, Port (B) in the middle, and Port (R) at the bottom. A horizontal line connects Port (2) to Port (B).](cbdfdade780e677eb1c1aef3081ce9ef_img.jpg)

+
+**Figure I.1/Q.552 – General hybrid**
+
+NOTE 1 – The balance port may not always be physically accessible in the hybrid, i.e. it may exist only notionally.
+
+The transmission properties of the hybrid are specified by the following parameters:
+
+- 2-wire impedance connected to the 2-wire port of the hybrid  $Z_2$
+- input impedance at the port (2) of the hybrid  $Z_T$
+- balance impedance at the port (B)  $Z_B$
+- matched loss between ports (R) and (2)  $L_R$
+- matched loss between ports (2) and (T)  $L_T$
+- balance return loss  $L_{br}$
+
+NOTE 2 – "Matched loss" implies that the loss is to be measured for the special case when the impedance  $Z_2$  is made equal to  $Z_T$ .
+
+The separation between transmit and receive signals by means of a hybrid depends mainly on the impedance matching at the 2-wire port of the hybrid between:
+
+- the impedance  $Z_2$  connected to the 2-wire port of the hybrid; and
+- the so-called balance impedance  $Z_B$  of the hybrid.
+
+The loss  $L_{TR}$  between ports (T) and (R) is given by the relation:
+
+$$L_{TR} = L_T + L_{br} + L_R \quad (I-1)$$
+
+where:
+
+$$L_{br} = 20 \cdot \log \left| \frac{Z_T + Z_B}{2Z_T} \cdot \frac{Z_2 + Z_T}{Z_2 - Z_B} \right| \text{dB} \quad (I-2)$$
+
+NOTE 3 –  $L_{br}$  is in general a function of frequency. Equations (I-1) and (I-2) apply for all possible designs of hybrids.
+
+In case of impedance  $Z_T$  being equal to  $Z_B$ ,  $L_{br}$  results in:
+
+$$L_{br} = 20 \cdot \log \left| \frac{Z_2 + Z_B}{Z_2 - Z_B} \right| \quad (I-3)$$
+
+NOTE 4 – This equation is similar to the "return loss"-equation used for the comparison of two impedances.
+
+A connection in a digital PSTN in principle consists of two analogue telephone sets which include the microphone and the earphone, the 2-wire analogue subscriber lines and the 4-wire digital connection. The transitions from 2-wire to 4-wire and vice versa are made by hybrids which are situated in the telephone set and in the exchange line circuit (see Figure I.2).

+
+Figure I.2/Q.552 – Telephone connection via 2-wire analogue subscriber lines
+
+At the telephone set, port (T) corresponds to the microphone, port (R) to the earphone receiver. The impedance  $Z_{2_{set}}$  is the cable input impedance of the subscriber line terminated by the 2-wire input impedance  $Z_{T_{ex}}$  of the digital exchange (nominal input impedance for open 4-wire loop). The loss  $L_{TR}$  corresponds to the sidetone loss.
+
+At the exchange line circuit, ports (T) and (R) correspond to the digital 4-wire ports. The impedance  $Z_{2_{ex}}$  is the cable input impedance of the subscriber line terminated by the 2-wire input impedance  $Z_{T_{set}}$  of the telephone set. The loss  $L_{TR}$  corresponds to the echo loss at the listener's exchange.
+
+It is immediately apparent that the impedance  $Z_2$  (i.e.  $Z_{2_{ex}}$  or  $Z_{2_{set}}$  respectively) must not vary too much from the balance impedance  $Z_B$  (i.e.  $Z_{B_{ex}}$  or  $Z_{B_{set}}$  respectively) if the balance return loss is to be kept high. To achieve this with different cable types of varying lengths the terminating impedances have to be chosen with care. This will be discussed in I.3 and I.4. An example will be given in I.8.
+
+## I.2 General equations for unloaded cables
+
+For the sake of completeness, the impedance equations for cables will be presented.
+
+For uniformly distributed lines the transmission characteristics are calculated from the electrical primary cable constants per unit length:
+
+$$R' \text{ in } \frac{\Omega}{\text{km}}; L' \text{ in } \frac{H}{\text{km}}; G' \text{ in } \frac{S}{\text{km}}; C' \text{ in } \frac{F}{\text{km}}; f \text{ in Hz}; \omega = 2\pi f$$
+
+NOTE –  $L'$  and  $G'$  can be disregarded for unloaded cables in the range of voiceband frequencies.
+
+The **image (characteristics) impedance** of a cable is:
+
+$$Z_C = \sqrt{\frac{R' + j\omega L'}{G' + j\omega C'}} \quad (\text{I-4})$$
+
+The **propagation constant** of a cable is:
+
+$$\gamma = \alpha + j\beta = \sqrt{(R' + j\omega L')(G' + j\omega C')} \quad (\text{I-5})$$
+
+and expresses the attenuation  $\alpha$  in nepers per unit length and the phase shift  $\beta$  in radians per unit length.
+
+If the cable is terminated by an impedance  $Z_T = Z_C$  the cable input impedance  $Z_2$  will also be equal to  $Z_C$  and therefore independent of the cable length. If the cable is terminated by an impedance  $Z_T \neq Z_C$  its **input impedance**  $Z_2$  is dependent on the loop length ( $l$ ) and will be:
+
+$$Z_2 = \frac{Z_T + Z_C \cdot \tan h(\gamma \cdot l)}{1 + \frac{Z_T}{Z_C} \cdot \tan h(\gamma \cdot l)} \quad (\text{I-6})$$
+
+Two impedances at port (2) can be compared by the **reflection coefficient**:
+
+$$r = \frac{Z_2 - Z_T}{Z_2 + Z_T} \quad (\text{I-7})$$
+
+## I.3 General impedance considerations of a hybrid
+
+The separation characteristic of a hybrid is defined by the impedances  $Z_2$ ,  $Z_T$  and  $Z_B$  (see equation I-2). The impedance  $Z_2$  is connected to the hybrid and is given by the subscriber line network while the impedances  $Z_T$  and  $Z_B$  are part of the hybrid itself and are to be chosen carefully.
+
+### I.3.1 Cable input impedance $Z_2$ and the hybrid input impedance $Z_T$
+
+If the cable is not terminated by its characteristic impedance  $Z_C$ , the cable input impedance  $Z_2$  depends on the cable parameters and the input impedance  $Z_T$  of the cable termination equipment (telephone set or exchange line circuit) (see equation I-6).
+
+At the port (2) of the telephone set, the input impedance  $Z_{2_{set}}$  is determined by the subscriber cable parameters and  $Z_{T_{ex}}$  of the exchange.
+
+At the port (2) of the exchange line circuit, the input impedance  $Z_{2_{ex}}$  is determined by the subscriber cable and  $Z_{T_{set}}$  of the telephone set (normally in a network different types of telephone sets with different input impedances exist).
+
+The better the termination impedance  $Z_T$  approximate to the characteristic impedance  $Z_C$  of the cable, the less the cable input impedance  $Z_2$  vary with the length. With regard to the balance impedance (see next clause) and due to the capacitive complex property of the characteristic impedance in the voice frequency range, it is advantageous to define also a capacitive complex impedance  $Z_T$  for the cable termination, i.e.  $Z_{T_{set}}$  for the telephone set or  $Z_{T_{ex}}$  respectively for the exchange line circuit. (However, in practice it is not always possible to choose an "optimum" terminating impedance as the only alternative because one must also consider what already exists in the real network. See the discussion in I.7.)
+
+### I.3.2 Balance impedance $Z_B$
+
+The fixed balance network  $Z_{B_{ex}}$  in the exchange line circuit has direct consequences for the talker echo performance at the listener's exchange while  $Z_{B_{set}}$  effects the sidetone for the telephone set. For practical reasons it is desirable to have only one balance impedance  $Z_B$  to make a balancing of the whole range of impedances  $Z_2$  in a network. (However, in those circumstances, when the impedance range seen by the exchange is very wide, one may need to choose several options for balance impedance.)
+
+In order to choose a suitable balance impedance  $Z_B$ , it is necessary to consider the network with regard to:
+
+- the types of cables and their cumulative length distribution;
+- the range of termination impedances and their tolerances;
+- the required balance return loss with regard to the transmission plan and the permissible echo limits.
+
+## I.4 Echo considerations
+
+### I.4.1 Talker echo loudness rating TELR
+
+The talker echo loudness rating TELR is calculated according to equation I-8 (see ITU-T G.111).
+
+$$TELR = SLR + RLR + L_e \quad (I-8)$$
+
+where SLR, RLR are the send and receive loudness ratings from the talker's side, referred to the 0 dBr digital transmit and receive ports of the exchange, and the echo loss  $L_e$  is the weighted average of  $L_{TR}$  (see equation I-1).
+
+NOTE – In ITU-T G.122, the weighting equation for TELR is specified for a linear frequency scale.
+
+### I.4.2 Sidetone masking rating STMR and listener sidetone rating LSTR
+
+The sidetone masking rating STMR can be computed for analogue terminals in a similar way, according to Annex A/G.111:
+
+$$STMR = SLR(set) + RLR(set) - 1 + L_{st} \quad (I-9)$$
+
+where SLR (set) and RLR (set) refer to the telephone set itself and  $L_{st}$  is the weighted average of  $L_{TR}$  (see equation I-1).
+
+The listener sidetone rating LSTR is:
+
+$$LSTR = STMR + D \quad (I-10)$$
+
+where  $D$  is the difference in sensitivity between direct and diffuse sound of the handset microphone.
+
+However,  $L_e$  and  $L_{st}$  can also be computed – according to ITU-T G.111 – as averages over a logarithmic frequency scale, preferably using a third-octave division, giving 14 points between 200 and 4000 Hz. The general equation is:
+
+$$L = -\frac{10}{m} \cdot \log \left\{ \sum_{i=1}^{14} K_i 10^{-0.1 \cdot m \cdot L_{TR}} \right\} \quad (I-11)$$
+
+In Table I.1 the weighting coefficients  $K_i$  for sidetone (from Table A.1/G.111) and  $K_i$  for echo (calculated with equation A.4-8/G.111) are summarized; for calculation of  $L_e$  (echo loss),  $m = 1$ ; for calculation of  $L_{st}$  (sidetone),  $m = 0.2$ .
+
+**Table I.1/Q.552 – Weighting coefficients  $K_i$   
+for talker echo ( $L_e$ ) and sidetone ( $L_{st}$ )**

+| 14 | 4000       | 0          | 0.05          |
+
+Between echo and sidetone calculation there is a difference in the weighting. The talker echo weighting is flat, while the sidetone weighting emphasizes the frequencies above 800 Hz. This implies that for the talker echo, an impedance matching is needed over the total speech band, while for the sidetone only the range above 800 Hz is of importance.
+
+## I.5 Applications
+
+A transmission plan for a telephone network must include, among a multitude of items, considerations for the loop plant design and the parameters of the telephone sets. As these factors differ among network operators, it is not surprising that different exchanges and balance impedances have been chosen as evidenced from Table 1 and Figure 11.
+
+In this context, it is useful to consider the limit for satisfactory sidetone and talker echo performance.
+
+For sidetone, the limiting parameter is the listener side tone rating LSTR, which should be higher than 13 dB. This guarantees that the listener will not be disturbed by room noise picked up via the listener sidetone path even under rather noisy conditions.
+
+For talker echo, the requirements on the talker echo loudness rating TELR depends on the particular network rule for applying echo cancellers, i.e. above which mean one-way transmission time  $T$  [ms] they must be deployed. ITU-T G.131 gives TELR as function of  $T$  [ms] for acceptable echo performance without echo control.
+
+## I.6 Analysis of loop impedance variation by means of a special impedance diagram
+
+Knowledge about the actual loop impedance conditions in a network can be obtained in several ways, for instance by field measurements. Another method is to collect the statistical data for the terminals and for the cables, types and lengths and then compute the impedances.
+
+One can proceed in several ways to analyse the impedance data and arrive to suitable impedance matchings. A fairly simple method for a quick analysis is to plot the impedances in a special type of diagram which is so designed that a certain distance between two impedance points always corresponds to the same return loss. This is achieved by making the abscissa and the ordinate
+
+$$X = k \cdot \ln |Z| \qquad Y = k \cdot \arg \{Z\} \text{ radians; } k \text{ is a constant}$$
+
+Figure I.3 shows the principle. The scale at the bottom of the figure can be used to estimate return losses. (For the sake of clarity, the impedance angles are graduated in degrees, not in radians.) Thus, in a plot containing several impedances their mutual return losses can be roughly estimated by inspection.
+
+The calibration for the scale with regard to a return loss  $A$  is derived from the expression:
+
+$$R = \frac{k}{2} \{R_x + R_y\}$$
+
+where:
+
+$$R_x = \ln \left\{ \frac{1 + 10^{-\frac{A}{20}}}{1 - 10^{-\frac{A}{20}}} \right\} \qquad R_y = 2 \cdot \text{arctg} \left\{ 10^{-\frac{A}{20}} \right\}$$
+
+Figure I.4 shows as an example impedance curves for constant return losses against 600  $\Omega$ . Note that the curves are almost circles for loss values  $> 10$  dB.

+
+Applications of this special diagram are also given in I.8.
+
+When a large amount of impedance data have to be analysed, it is more convenient to make separate impedance diagrams for frequency points included in the survey in order to find an optimum balance impedance point for that frequency. In principle, this optimum can be chosen according to different criteria. One way would be to choose the point as "the centre of gravity" which give the best "r.m.s." average of echo (or sidetone) suppression at that frequency for the cases considered. Another way would be to enclose the points with the smallest circle and choose the centre of this circle as the optimum impedance point.
+
+When it comes to match these points with a suitable impedance function, the echo loss or sidetone weighting should be considered.
+
+## 1.7 Conclusions
+
+By the methods shown here, a network planner can find optimum terminating and balancing impedances for the networks he is responsible for. In general, if unloaded cable are used in a controlled network, a capacitive complex impedance as a compromise may be preferred as the nominal impedance. Then, quite high echo losses can be obtained which may reduce the need of echo cancellors. However, for many networks it may not be very critical to obtain very high echo losses in the subscriber network because, for other reasons, echo cancellors must be/are inserted in many trunks anyhow. Likewise, the levels in the network can be such that the send and receive sensitivity of the telephone sets on short lines need not be too high, i.e. the nominal exchange impedance need not be complex. In that case, for regulated telephones the sidetone circuit is designed for a medium-to-long cable, terminated with for instance 600  $\Omega$ . Moreover, in deregulated telecom markets the network operator may not have a very close control of what terminals are used in their network and what their parameters are.
+
+For other networks, however, one may wish to avoid a widespread of echo cancellors and/or use more sensitive telephone sets near the exchange. Then the rules and observations mentioned earlier in this appendix are worth noticing when choosing input and balance impedances.
+
+### 1.8 Examples of impedances $Z_2$ and compromise nominal impedances $Z_T$ and $Z_B$
+
+Only to illustrate the subject given in 1.1 to 1.7 to the reader, this clause gives some detailed numerical examples for a chosen limited range of subscriber cables. It is also assumed that the network operator had the authority to prescribe a common nominal impedance to be used for future equipment. However, the operator also had to consider equipment with 600  $\Omega$  resistive input impedance.
+
+The problem for the operator is to choose the input impedance  $Z_{T_{ex}}$  of the digital exchange in such a way that the sidetone performance of the telephone set becomes adequate, and to choose the input impedance  $Z_{T_{set}}$  of the telephone set so that the talker echo for the subscriber at the other end is adequately suppressed.
+
+Some network operators have found that by their telephone set designs, sidetone and therefore input impedance is not a very critical parameter such as it is with more sensitive telephones.
+
+It can be seen from equation (I-4) that the characteristic impedance of the unloaded cable is inversely proportional to the cable diameter and inversely proportional to the square root of the cable capacitance. Therefore, it is not possible to find one unique nominal impedance to match exactly all the types of cables that usually are found in the network of a service provider. Moreover, many analogue networks contain equipment with an impedance of nominally 600  $\Omega$  resistive. For the determination of a compromise nominal impedance  $Z_T$  these impedances must also be considered. An overview of the problems and discussion of the methodology is given in [1] and [2].
+
+Some calculated curves will be presented as an illustration for a typical unloaded 0.5 mm-Cu-subscriber cable with:
+
+$$R' = 168 \frac{\Omega}{\text{km}}, L' = 0.7 \frac{\text{mH}}{\text{km}}, G' = 1 \frac{\mu\text{S}}{\text{km}}, C' = 50 \frac{\text{nF}}{\text{km}}, 300 \text{ Hz} \leq f \leq 3.4 \text{ kHz} \text{ (data see [3])}$$
+
+#### 1.8.1 Cable input impedance $Z_2$ and hybrid input impedance $Z_T$
+
+The cable input impedance  $Z_2$  is calculated for a terminating impedance:
+
+- $Z_T = 600 \Omega$  resistive termination, representing the nominal impedance of many existing telephone sets;
+- $Z_T = Z_{\text{ETSI}} = 270 \Omega + (750 \Omega \parallel 150 \text{ nF})$ , representing the nominal impedance of future telephone sets.
+
+The ETSI-impedance is a compromise which has been recommended to be used both as the nominal input impedance of equipment in the 2-wire network (exchanges and terminals) and as balance impedance in exchanges.
+
+NOTE – The input impedance of telephone sets has a rather wide tolerance, some sets are often slightly inductive.
+
+Figure I.5 shows the input impedance of a cable with length variation  $0 \text{ km} \leq l \leq 4 \text{ km}$  and terminated with  $600 \Omega$  resistive, and similarly Figure I.6 for the ETSI-impedance  $Z_{\text{ETSI}}$  as termination.

The horizontal axis ranges from 0 to 1400  $\Omega$  with major ticks every 200  $\Omega$ . The vertical axis ranges from 0 to -800  $\Omega$  with major ticks every 200  $\Omega$ . Five curves represent different cable lengths: 0 km, 1 km, 2 km, 3 km, and 4 km. All curves start at  $(600, 0)$  on the real axis. As length increases, the curves move further into the negative imaginary region. Frequency markers are placed along the curves: 3400 Hz at the top-left of the 0 km curve, 2000 Hz at the top-left of the 1 km curve, 1000 Hz at the bottom of the 2 km curve, 500 Hz at the bottom of the 3 km curve, and 300 Hz at the bottom of the 4 km curve.

+To compare the effect of different cable terminations, Figure I.7 shows the range of the magnitude of the reflection coefficient versus the frequency with the cable length as parameter (calculated with equation I-7).

+
+#### I.8.2 Balance impedance $Z_B$
+
+If only terminals with the ETSI input impedance are used, it is possible to obtain a better average balance return loss by choosing a  $Z_B$  that differs from  $Z_{ETSI}$ .
+
+A three-element balance network  $Z_{B_{calc}}$  was found by an iterative calculation process with the following preconditions regarding the echo loss  $L_e$ :
+
+- cable lengths and type:  $0 \text{ km} \leq l \leq 4 \text{ km}$ , 0.5 mm-Cu;
+- cable termination impedance  $Z_T = Z_{ETSI} = 270 \Omega + (750 \Omega \parallel 150 \text{ nF})$ ;
+- $L_e$  should be a maximum in the range of the average length (resulting of the cumulative length-distribution of a network; in this example an average length of 1.7 km is assumed);
+- for  $l = 0 \text{ km}$  and  $l = 4 \text{ km}$ :  $L_e$  should be a minimum but the value should be as high as possible and nearly the same.
+
+The result of the calculation is:
+
+$$Z_{B_{calc}} = 230 \Omega + (1040 \Omega \parallel 160 \text{ nF})$$
+
+NOTE – For low frequencies  $|Z_{B_{calc}}| \approx |Z_{ETSI}| + (1.7 \text{ km} \cdot R')$ .
+
+Figure I.8 shows the locus of the balance impedance  $Z_{B_{calc}}$  in comparison with the ETSI-impedance  $Z_{ETSI}$ .

+
+### I.8.3 Application of the special impedance diagram
+
+Figures I.9 and I.10 show the same input impedance curves as depicted in Figures I.5 and I.6; however, in the special impedance diagram mentioned above, the same type of cable is terminated with  $Z_{ETSI}$  and  $600 \Omega$  respectively.
+
+Also depicted are two examples of balance impedances, namely  $Z_{ETSI}$  and  $Z_{B_{calc}}$ . As can be seen directly,  $Z_{B_{calc}}$  is more optimal if the  $Z_{ETSI}$ -termination is the only one allowed. However, if only 600  $\Omega$ -termination have to be considered,  $Z_{ETSI}$  is the better choice. It is also apparent that a complex impedance termination results in much less impedance deviations so that better balancing with a single 3-element-impedance-network is possible.
+
+Note that the ETSI-impedance was obtained from more data than just 0.5 mm Cu-cables.

+
+The figure is a graph showing the input impedance  $Z_2$  of a 0.5 mm cable. The vertical axis represents the phase  $\phi(Z)$  in degrees, ranging from 0 to 50. The top horizontal axis shows the magnitude of the impedance  $Z$  in  $k\Omega$ , ranging from 0.3 to 1.5. The bottom horizontal axis shows the Return Loss in dB, ranging from  $\infty$  to 6. The graph displays several curves for different cable lengths: 0 km, 1 km, 2 km, 3 km, and 4 km. Two specific curves are labeled 'a' and 'b', corresponding to  $Z_{ETSI}$  and  $Z_{B_{calc}}$  respectively. Frequency markers are present at 300 Hz, 500 Hz, 1000 Hz, 2000 Hz, and 3400 Hz. The curves show that as the cable length increases, the input impedance deviates more from the ideal 600  $\Omega$  termination, especially at higher frequencies.

+#### I.8.4 Echo considerations
+
+##### I.8.4.1 Echo loss $L_e$
+
+The echo loss  $L_e$  is the weighted average of  $L_{TR} = L_T + L_{br} + L_R$  (see equation I-1).
+
+Figure I.11 shows the echo loss at the listener's exchange for different combinations of impedances. At the exchange line circuit, the losses  $L_T = 0 \text{ dB}$  and  $L_R = 7 \text{ dB}$  are assumed.

+
+##### I.8.4.2 Sidetone loss $L_{st}$
+
+The sidetone loss  $L_{st}$  is the weighted average of  $L_{TR} = L_T + L_{br} + L_R$  (see equation I-1). Figure I.12 shows the sidetone loss at the hybrid of a telephone set for different balance networks. At the telephone set, the losses  $L_T = L_R = 0$  dB are assumed.
+
+The sidetone loss  $L_{st}$  can be transformed into a STMR value for the set in the following way. Referred to the 0 dBr point of the exchange, the "target value" is  $(SLR + RLR) = 10$  dB. The sum of the T and R-pads usually is  $(T + R) = 7$  dB. Suppose the line attenuation is 3 dB, then for the set itself  $\{SLR(set) + RLR(set)\} = 10$  dB  $- 7$  dB  $- 2 \times 3$  dB  $= -3$  dB. Thus, using equation (I-9):  $STMR = L_{st} - 4$ . Judging from the  $L_{st}$  – values of Figure I.8, there is no problem with a too loud sidetone.

+# **Transmission characteristics at 4-wire analogue interfaces of digital exchanges**
+
+## **Summary**
+
+This Recommendation provides characteristics for 4-wire analogue interfaces, input and output connections with 4-wire analogue interfaces and half-connections with 4-wire analogue interfaces in digital transit and combined local and transit exchanges in accordance with definitions given in ITU-T Rec. Q.551.
+
+This Recommendation is intended for switching connections that may be part of an international long-distance connection via 4-wire line circuits interconnected by 4-wire exchanges. Since 4-wire analogue interfaces on digital exchanges may connect with circuits which are used for both international and national traffic, the same values recommended for international connections may also be used for connections entirely within the national network.
+
+## **Source**
+
+ITU-T Recommendation Q.553 was revised by ITU-T Study Group 15 (2001-2004) and approved under the WTSA Resolution 1 procedure on 29 November 2001.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# **Transmission characteristics at 4-wire analogue interfaces of digital exchanges**
+
+# **1 General**
+
+This Recommendation provides characteristics for:
+
+- 4-wire analogue interfaces (Type C<sub>11</sub>, C<sub>12</sub> and C<sub>13</sub>);
+- input and output connections with 4-wire analogue interfaces; and
+- half connections with 4-wire analogue interfaces
+
+in digital transit and combined local and transit exchanges, in accordance with the definitions given in ITU-T Rec. Q.551, particularly in Figures 1/Q.551 and 2/Q.551.
+
+The characteristics of the input and output connections of a given interface are not necessarily the same. The characteristics of half connections are not necessarily identical for different types of interfaces.
+
+This Recommendation is intended for switched connections that may be part of an international long-distance connection via 4-wire line circuits interconnected by 4-wire exchanges. Since 4-wire analogue interfaces of digital exchanges may connect with circuits which are used for both international and national traffic, the same values recommended for international connections may also be used for connections entirely within the national network.
+
+## **2 Characteristics of interfaces**
+
+### **2.1 Characteristics common to all 4-wire analogue interfaces**
+
+### **2.1.1 Exchange impedance**
+
+#### **2.1.1.1 Nominal value**
+
+The nominal impedance at the analogue input and output interfaces should be 600 ohms, balanced.
+
+#### **2.1.1.2 Return loss**
+
+The return loss at the equipment ports, measured against the nominal impedance, should not be less than 20 dB over the frequency range 300 Hz to 3400 Hz.
+
+NOTE – For output measurement, the exchange test point T<sub>i</sub> must be driven by a PCM signal corresponding to the decoder output value number 0 for the  $\mu$ -law or decoder output value number 1 for the A-law. (See 1.2.3.1/Q.551.)
+
+### **2.1.2 Impedance unbalance about earth**
+
+The value for the Longitudinal Conversion Loss (LCL) at the equipment ports as defined in 4.1.3/G.117, with the circuit under test in the normal talking state, should exceed the minimum values of Figure 1, in accordance with ITU-T Rec. K.10.
+
+NOTE 1 – A network operator may adopt other values and, in some cases, a wider bandwidth, depending upon actual conditions in its telephone network.
+
+NOTE 2 – A limit may also be required for the Transverse Conversion Loss (TCL) as defined in 4.1.2/G.117, if the exchange termination is not reciprocal with respect to the transverse and longitudinal connections. A suitable limit would be 40 dB to ensure an adequate near-end crosstalk attenuation between interfaces.

+![Figure 1/Q.553: A graph showing the minimum values of LCL (Loss in dB) versus Frequency (f in Hz). The y-axis ranges from 0 to 50 dB. The x-axis ranges from 0 to 3400 Hz. The graph shows a shaded region representing the minimum loss values. The loss is 40 dB from 0 to 300 Hz, then increases to 46 dB at 600 Hz, and remains constant at 46 dB up to 3400 Hz. The shaded area is bounded by the lines f=300, f=600, and f=3400.](c3c305cefbac2e7b13be34ab87054d1e_img.jpg)

+
+#### Test method
+
+LCL should be measured in accordance with the principles given in 4.1/O.9. Figure 2 shows the basic measuring arrangement. Arrangements containing two resistors each of value  $R/2$  may also be used (see clause 5/O.9).
+
+Measurements of the longitudinal and transverse voltages should be performed by means of a frequency-selective level meter.

A sinusoidal oscillator is connected to a series combination of a resistor R/4 and a parallel combination of a resistor R and a voltmeter V_L1. This is followed by a C1 interface. The 'Item under test' is connected to the interface. The input connection of the item under test is connected to a series combination of a resistor R and a voltmeter V_T1. The output connection of the item under test is connected to a series combination of a resistor R and a voltmeter V_T1. The item under test has two exchange test points, T_o and T_i, indicated by arrows.](c0e88e4bd3a209b66ee7cb67e1cec2be_img.jpg)

+
+### 2.1.3 Relative levels
+
+In assigning the relative levels to the interfaces, the limiting of "difference in transmission loss between the two directions of transmission" in Annex A/G.121 has been taken into account. For the national extension, this is the value "loss (t-b)–loss (a-t)". (See the text in the cited
+
+Recommendation for guidance.) This difference is limited to  $\pm 4$  dB. However, to allow for additional asymmetry of loss in the rest of the national network, only part of this difference can be used by the digital exchange.
+
+#### 2.1.3.1 Nominal levels
+
+The nominal relative levels at the analogue input and output interfaces of the digital exchange depend on the type of equipment which is connected to the exchange. (See Figure 1/Q.551.)
+
+In practice, it may be necessary to compensate for the loss between the output interfaces of the digital exchange and the input ports of the connected equipment to fulfil transmission plan conditions. The definition of adjustable steps for and the location of this compensation (digital exchange or connected equipment) is within national competence.
+
+Nominal values of relative levels are given in 2.2.1, 2.3.1 and 2.4.1 for the different types of half connections.
+
+#### 2.1.3.2 Tolerances of relative levels
+
+The difference between the actual relative level and the nominal relative level should lie within the following ranges:
+
+- input relative level:  $-0.3$  to  $+0.7$  dB;
+- output relative level:  $-0.7$  to  $+0.3$  dB.
+
+These differences may arise, for example, from design tolerances, cabling (between analogue equipment ports and the DF) and adjustment increments.
+
+NOTE – Adjustment of the relative level should be made in accordance with clause 3/G.712.
+
+### 2.2 Characteristics of interface C<sub>11</sub>
+
+According to Figure 1/Q.551, the interface C<sub>11</sub> of a digital exchange is intended to interwork with the channel translating equipment of an FDM system.
+
+### 2.2.1 Values of nominal levels
+
+The nominal values of relative levels at the channel translating equipment are specified in Table 2/G.232 for the two recommended cases. With the pads in the channel translating equipment set to zero, these values are:
+
+|     | Case 1      | Case 2      |
+|-----|-------------|-------------|
+| $R$ | $+4.0$ dBr  | $+7.0$ dBr  |
+| $S$ | $-14.0$ dBr | $-16.0$ dBr |
+
+The nominal values of relative levels at the digital exchange must be adjusted to compensate for the total loss between the interface of the digital exchange and the channel translating equipment. Therefore:
+
+$$L_i = R - A_R$$
+
+$$L_o = S + A_S$$
+
+where:
+
+$A_R$  is the total loss in the receive path, e.g. direction of transmission from channel translating equipment to digital exchange.
+
+$A_S$  is the total loss in the send path, e.g. direction of transmission from digital exchange to channel translating equipment.
+
+## 2.3 Characteristics of interface C<sub>12</sub>
+
+According to Figure 1/Q.551, the interface C<sub>12</sub> of a digital exchange is intended to interwork with the incoming and outgoing relay set of an analogue 4-wire exchange. (See Figure 1/Q.45 *bis.*)
+
+### 2.3.1 Values of nominal levels
+
+The nominal values of relative levels at the relay set of an analogue exchange are consistent with Table 2/G.232 for the two recommended cases. These values are:
+
+|     | Case 1     | Case 2     |
+|-----|------------|------------|
+| $R$ | – 14.0 dBr | – 16.0 dBr |
+| $S$ | + 4.0 dBr  | + 7.0 dBr  |
+
+The nominal values of relative levels at the digital exchange must be adjusted to compensate for the total loss between the interface of the digital exchange and the relay sets of the analogue exchange.
+
+Therefore:
+
+$$L_i = R - A_R$$
+
+$$L_o = S + A_S$$
+
+where:
+
+$A_R$  is the total loss in the receive path, e.g. direction of transmission from relay set to digital exchange.
+
+$A_S$  is the total loss in the send path, e.g. direction of transmission from digital exchange to relay set.
+
+### 2.4 Characteristics of interface C<sub>13</sub>
+
+According to Figure 1/Q.551, the interface C<sub>13</sub> of a digital exchange is intended to connect to a 4-wire analogue switching stage. (See Figure 1/G.142, case 5.)
+
+### 2.4.1 Values of nominal levels
+
+The nominal values of relative levels are determined by the relative levels of the analogue 4-wire switching stages in the national transmission plans. For example, if these relative levels are –3.5 dBr in both directions of transmission, the nominal input and output levels of a C<sub>13</sub> interface should be:
+
+$$L_i \quad L_o \quad 3.5 \text{ dBr}$$
+
+Different levels at the switching stages and transmission loss between interface C<sub>13</sub> and the switching stages can require adjusting these levels.
+
+## **3 Characteristics of half connections**
+
+## **3.1 Characteristics common to all 4-wire analogue interfaces**
+
+### **3.1.1 Transmission loss**
+
+#### **3.1.1.1 Nominal value**
+
+The nominal transmission loss, according to 1.2.4.1/Q.551 is defined for input and output connections of a half connection with 4-wire analogue interface in 3.2.1, 3.3.1 and 3.4.1.
+
+#### **3.1.1.2 Tolerances of transmission loss**
+
+The difference between the actual transmission loss and the nominal transmission loss of an input or output connection of the same half connection according to 2.1.3.2 should lie within the following values:
+
+$$- 0.3 \text{ to } + 0.7 \text{ dB}$$
+
+These differences may arise for example, from design tolerances, cabling (between analogue equipment ports and the DF) or adjustment increments.
+
+#### **3.1.1.3 Short-term variation of loss with time**
+
+When a sine-wave test signal at the reference frequency of 1020 Hz and at a level of  $-10 \text{ dBm}0$  (if preferred, the value  $0 \text{ dBm}0$  may be used) is applied to an analogue interface of any input connection, or a digitally simulated sine-wave signal of the same characteristics is applied to the exchange test point  $T_i$  of any output connection, the level at the corresponding exchange test point  $T_o$  and the level at the analogue interface of the output connection respectively, should not vary by more than  $\pm 0.2 \text{ dB}$  during any 10-minute interval of typical operation under the steady state condition permitted variations in the power supply voltage and temperature.
+
+#### **3.1.1.4 Variation of gain with input level**
+
+With a sine-wave test signal at the reference frequency of 1020 Hz and at a level between  $-55 \text{ dBm}0$  and  $+3 \text{ dBm}0$  applied to the analogue interface of any input connection, or with a digitally simulated sine-wave signal of the same characteristic applied to the exchange test point  $T_i$  of any output connection, the gain variation of that connection, relative to the gain at the input level of  $-10 \text{ dBm}0$ , should lie within the limits given in Figure 3.
+
+The measurement should be made with a frequency selective meter to reduce the effect of the exchange noise. This requires a sinusoidal test signal.
+
+![Figure 3/Q.553 – Variation of gain with input level. The graph shows gain variation in dB on the y-axis (from -1.6 to 1.6) against input level in dBm0 on the x-axis (from -55 to +3).

+#### 3.1.1.5 Loss distortion with frequency
+
+According to 1.2.5/Q.551, the loss distortion with frequency of any input or output connection should lie within the limits shown in the mask of Figure 4 a) and b), respectively. The preferred input level is  $-10$  dBm0.

+
+Taking the minimum group delay, in the frequency range between 500 Hz and 2800 Hz, of the input or output connection as the reference, the group delay distortion of that connection should lie within

+
+#### 3.1.3 Noise
+
+#### 3.1.3.1 Weighted noise
+
+Two components of noise should be considered: noise arising from the coding process, and noise from analogue sources such as signalling equipment and the analogue circuit for impedance and level adaptation. The first component is limited to  $-67$  dBm0p for input connections and to  $-70$  dBm0p for output connections in accordance with Table 7/G.712; the other component to  $-(67 + 3)$  dBm0p  $= -70$  dBm0p for one 4-wire analogue interface including circuit noise in accordance with clause 3/G.123.
+
+This results in the maximum values for the overall weighted noise in the talking state at the  $C_1$ -interface of a digital exchange:
+
+- Equipment with signalling on separate wires:
+  - input connection:  $-67.0$  dBm0p;
+  - output connection:  $-70.0$  dBm0p.
+- Equipment with signalling on the speech wires:
+  - input connection:  $-65.2$  dBm0p;
+  - output connection:  $-67.0$  dBm0p.
+
+#### 3.1.3.2 Single frequency noise
+
+The level of any single frequency (in particular the sampling frequency and its multiples), measured selectively at the interface of an output connection should not exceed  $-50$  dBm0. Between 300 and 3400 Hz, the level of any single frequency measured selectively and corrected by the psophometric weighting factor (see Table 1/O.41) should not exceed  $-73$  dBm0 (provisional value).
+
+NOTE – See 1.2.3.1/Q.551 with regard to common measurement conditions.
+
+### 3.1.4 Crosstalk
+
+For crosstalk measurements, auxiliary signals are injected as indicated in Figures 6 to 9. These signals are:
+
+- the quiet code (see 1.2.3.1/Q.551);
+- a low level activating signal. A suitable activating signal is, for example, a sine-wave signal at a level in the range from  $-33$  to  $-40$  dBm0. Care must be taken in the choice of frequency
+
+and the filtering characteristics of the measuring apparatus in order that the activating signal does not significantly affect the accuracy of the crosstalk measurement.

+###### 3.1.4.1.1 Far-end and near-end crosstalk
+
+A sine-wave test signal at the reference frequency of 1020 Hz and at a level of 0 dBm0, applied to an analogue input interface, should not produce a level exceeding -73 dBm0 for Near-End Crosstalk (NEXT) or -73 dBm0 for Far-End Crosstalk (FEXT), at the output of any other half connection. (See Figure 6.)

+**Figure 11/Q.553 – Limits for signal-to-total distortion ratio as a function of input level for input or output connection with signalling on the speech wires**
+
+The values of Figure 11 include the limits for the coding process given in Figure 12/G.712 and the allowance for the noise contributed via signalling circuits from the exchange power supply and other analogue sources which is limited to  $-(67 + 3)$  dBm0p =  $-70$  dBm0p for one 4-wire analogue interface by clause 3/G.123.
+
+### 3.1.6 Discrimination against out-of-band signals applied to the input interface
+
+(Applicable only to input connections.)
+
+#### 3.1.6.1 Input signals above 4.6 kHz
+
+With any sine-wave signal in the range from 4.6 kHz to 72 kHz applied to the analogue interface of an input connection at a level of  $-25$  dBm0, the level of any image frequency measured at the exchange test point  $T_0$  of the input connection should be at least 25 dB below the level of the test signal. This value may need to be more stringent to meet the overall requirement.
+
+#### 3.1.6.2 Overall requirement
+
+Under the most adverse conditions encountered in a national network, the half connection should not contribute more than 100 pW0p of additional noise in the band 10 Hz to 4 kHz at the output of the input connection, as a result of the presence of out-of-band signals at the input port of the input connection.
+
+### 3.1.7 Spurious out-of-band signals received at the output interface
+
+(Applicable only to an output connection.)
+
+#### 3.1.7.1 Level of individual components
+
+With a digitally simulated sine-wave test signal in the frequency range 300 to 3400 Hz and at a level of 0 dBm0 applied to the exchange test point  $T_i$  of a half connection, the level of spurious out-of-band image signals measured selectively at the analogue interface of the output connection should be lower than  $-25$  dBm0. This value may need to be more stringent to meet the overall requirement.
+
+#### 3.1.7.2 Overall requirement
+
+Spurious out-of-band signals should not give rise to unacceptable interference in the equipment connected to the digital exchange. In particular, the intelligible and unintelligible crosstalk in a connected FDM channel should not exceed a level of  $-65$  dBm0 as a consequence of the spurious out-of-band signals at the half connection.
+
+## 3.2 Characteristics for interface $C_{11}$
+
+### 3.2.1 Nominal value of transmission loss
+
+According to the relative levels defined in 2.2.1, the nominal transmission losses of a half connection with a  $C_{11}$  interface are:
+
+- input connection:  $R - A_R$ ;
+- output connection:  $-S - A_S$ .
+
+See 2.2.1 for definitions for  $R$ ,  $S$ ,  $A_R$  and  $A_S$ .
+
+## 3.3 Characteristics for interface $C_{12}$
+
+### 3.3.1 Nominal value of transmission loss
+
+According to the relative levels defined in 2.3.1, the nominal transmission losses of a half connection with a  $C_{12}$  interface are:
+
+- input connection:  $R - A_R$ ;
+- output connection:  $-S - A_S$ .
+
+See 2.2.1 for definitions for  $R$ ,  $S$ ,  $A_R$  and  $A_S$ .
+
+## 3.4 Characteristics for interface $C_{13}$
+
+### 3.4.1 Nominal value of transmission loss
+
+According to the relative levels defined in 2.4.1, the nominal transmission losses of a half connection with a  $C_{13}$  interface are:
+
+- input connection:  $-3.5$  dB;
+- output connection:  $3.5$  dB.
+
+Different levels at the switching stages and transmission loss between interface C<sub>13</sub> and the switching stages can require adjusting these losses.

+## **7 INTERWORKING REQUIREMENTS FOR NEW SIGNALLING SYSTEMS**
+
+### **7.1 *Treatment of new signals in another signalling system***
+
+In order to facilitate the interworking between new signalling systems and existing ones, it is desirable to elaborate rules to be taken into account when specifying the new signalling system(s). Since compatibility between all CCITT Signalling Systems must be ensured, any newly developed system has to meet the following requirements with regard to interworking:
+
+- a) new signalling systems should be capable of processing all interworking events specified for the existing signalling systems without losing or adding information elements.
+
+This is best achieved by the concept of transparency, whereby the signals of all existing systems have a unique translation into the new system and back again. In this way a tandem connection via an interposed link employing the new signalling system will neither add nor subtract from the information transfer that would otherwise have occurred had the new signalling system not been present;
+
+- b) newly developed systems should not lead to any modification to the specifications covering the present signalling systems except that the translation of new interworking events arising from the meanings of new signals in the new system will need to be defined for the existing signalling systems.
+
+In order that the new signals should cause the minimum loss or gain of information when interworking with existing signalling systems, any new signals should, if possible, not contain any information elements already existing. Hence it is better that these new signals convey only a single meaning rather than a multiple meaning as occurs in some existing systems (e.g. Signalling System R2 signal I-14 corresponds to FITE 8 which combines the elements of FITE 3 and FITE 5). Therefore, only one new information element will be associated with the new signal and only one new FITE or BITE will be needed.
+
+In some cases the new signal will be translated into a presently defined signal of an existing system and hence will cause the addition or, more often, the loss of information. In some cases, no electrical signal being available, all the information may be lost or a tone may need to be used. In the case of Signalling Systems R2, No. 6 and No. 7, some reserved signals exist within the capacity of these systems and such signals may be introduced to enhance the signalling system and provide an interworking capability.
+
+However it should be borne in mind that with such existing systems, it may not be easy or desirable to modify existing equipment, and even if such modification were possible, in the transitional period the interworking of existing and enhanced signalling equipment of the same system must also be considered.
+
+In view of the difficulties of interworking with existing signalling systems, new features of signals should only be introduced in a new system if there are good operational reasons for doing so.
+
+### **7.2 *Reserve for national use***
+
+In practice, provision of appropriate spare signalling capacity in a new system reserved for national/regional use cannot be avoided. In such a case, precautions must be taken to prevent signals with an individual national meaning from entering the international network.
+
+One general objective of a new signalling system should be to meet also the national requirements in order to avoid national versions of a given signalling system as far as possible.
+
+### 7.3 *Unambiguous specifications*
+
+After a clear specification of a new feature to be included in a signalling system, the related signalling procedures should be specified in a unique and standard form. The same applies to the signals involved.
+
+The designation of signals of different signalling systems, which carry the same information, should be the same.
+
+### 7.4 *Escape codes*
+
+It is obvious that appropriate spare capacity should be provided in order to cope with future demands. One way of doing so is the provision of escape codes.

+Flowchart for Incoming Signalling System No. 5 (Q.612). The process starts at '00 Idle', proceeds through 'Seizing', 'SPITE 1 Activate register function', and '01 Wait for register activation'. It then branches into 'SPITE 2 register function activated' and 'Clear-forward'. From 'SPITE 2', it goes to 'Proceed-to-send', which starts timers t1 (10-20 s) and t2 (20-40 s). It then enters '02 Wait for register signal'. From here, it can receive 'Register signal «KP2»' or 'Register signal «KP1»', which leads to 'Stop t1'. 'Clear-forward' leads to 'Stop t1'. 'τ1' leads to 'Stop t2'. Both 'Stop t1' and 'Stop t2' lead to '03 Wait for next register signal'. From '03', it can receive a 'Register signal'. If 'ST-signal' is 'No', it goes to 'SPITE 11'. If 'SPITE 11' is 'Yes', it goes to 'SPITE 3 Deactivate register function', then 'Release-guard', and back to '00 Idle'. If 'SPITE 11' is 'No', it loops back to '03'. If 'ST-signal' is 'Yes', it goes to 'Stop t2', then 'SPITE 35 Ignore further register signals', then 'SPITE 12 Perform digit analysis', and to connector '7'. 'Clear-forward' from 'Register signal' leads to 'Stop t2', then 'SPITE 3 Deactivate register function', then 'Release-guard', and back to '00 Idle'. 'τ2' leads to 'SPITE 3 Deactivate register function', then 'Busy-flash', then 'Start t3' (10-20 s), and to connector '8'. Various connectors (1, 2, 3, 4, 5, 6, 7, 8) are marked with subscripts 1 or 2. Connector reference numbers 00, 01, 02, 03, 1, 2, 3, 4, 5, 6, 7, 8 are listed on the left margin.

+The flowchart illustrates the logic for Incoming Signalling System No. 5. It begins with two entry points: connector 7 (labeled 1, 2) and connector 8 (labeled 1).  
+ - **State Machine 04 (Wait for digit analysis):** This path starts at connector 7. It branches into several processing blocks: SPITE 14 (Routing information), SPITE 13, SPITEs 15, 16, 17, SPITEs 18, 19, Register signal, Clear-forward, and  $\tau_2$ . SPITE 14 leads to 'Activate inter-working', which then leads to FITE 1. FITE 1 leads to a decision 'Any more digits?'. If 'Yes', it loops back to 'Activate inter-working'. If 'No', it leads to SPITE 23. SPITE 23 leads to a decision 'Which Z-digit?'. If 'Yes', it leads to connector 12 (labeled 3). If 'No', it leads to a horizontal bus with FITE 9, FITE 10, FITE 11, FITE 12, FITE 13, and FITE 17. This bus leads to a decision 'ST received?'. If 'Yes', it leads to connector 11 (labeled 3). If 'No', it leads to connector 10 (labeled 3). SPITE 13 leads to connector 1 (labeled 1). SPITEs 15, 16, 17 lead to 'Stop  $t_2$ ', which then leads to connector 5 (labeled 1). SPITEs 18, 19 lead to 'Stop  $t_2$ ', which then leads to connector 9 (labeled 2). Register signal leads to a decision 'ST-signal?'. If 'No', it leads to connector 2 (labeled 1). If 'Yes', it leads to 'Stop  $t_2$ ', which then leads to connector 7 (labeled 2). Clear-forward leads to connector 2 (labeled 1).  $\tau_2$  leads to connector 5 (labeled 1).  
+ - **State Machine 05 (Wait for acknowledgement):** This path starts at connector 8. It branches into Acknowledgement, Clear-forward, and  $\tau_3$ . Acknowledgement leads to 'Stop  $t_3$ ', which then leads to connector 9 (labeled 2, 3). 'Stop  $t_3$ ' leads to connector 13 (labeled 13), which leads to 'Wait for clear-forward', which then leads to Clear-forward, which leads to connector 4 (labeled 1). Clear-forward leads to 'Stop  $t_3$ ', which then leads to connector 4 (labeled 1).  $\tau_3$  leads to connector P1 (labeled 1), which is associated with 'Procedures for time-out routine'.  
+ - **Connector References:** A vertical list on the left side provides connector references for various points in the flowchart: 7, 8; 1, 2, 5; 5, 9; 9, 7, 4; 12; 10, 11.

+
+The flowchart illustrates the signaling process for Incoming Signalling System No. 5. It begins at connector 17 (3, 4) leading to state 09 'Wait for acknowledgement'. From here, four paths emerge: 'Acknowledgement' leading to 'Stop t3' and then to connector 18 (4); 'Clear-forward' leading to 'Stop t3' and then to connector 19 (4); 'BITE 25' leading to connector 17 (4); and a timeout path  $\bar{t}_3$  leading to connector P2 (4), which is part of 'Procedures for time-out routine'. From connector 18 (4), the path goes to decision 'BITE 25 received'. If 'Yes', it goes to connector 20 (4). If 'No', it goes to connector 18 (4) and loops back to state 09. From connector 20 (4), the path goes to state 10 'Answered'. From state 10, three paths emerge: 'Clear-forward' leading to connector 19 (3, 4 (3x)) and then to state FITE 22; 'BITE 25' leading to connector 20 (4) and then to state 'Clear-back'; and 'Forward-transfer' leading to state FITE 23 and then to connector 18 (4). From state FITE 22, the path goes to state SPITE 8 'Release all equipment', then to state 'Release-guard', and finally to state 00 'Idle'. From state 'Clear-back', the path goes to state 'Start t3' (with  $t_3 = 10-20\text{ s}$ ), then to connector 21 (4), and then to state 11 'Wait for acknowledgement'. From state 11, four paths emerge: 'Acknowledgement' leading to 'Stop t3' and then to connector 19 (4); 'Clear-forward' leading to 'Stop t3' and then to connector 19 (4); 'BITE 22' leading to connector 21 (4); and a timeout path  $\bar{t}_3$  leading to connector P3 (4), which is part of 'Procedures for time-out routine'. From connector 21 (4), the path goes to decision 'BITE 22 received'. If 'Yes', it goes to connector 19 (4). If 'No', it goes to connector 22 (4) and then to state 12 'Clear-back'. From state 12, three paths emerge: 'BITE 22' leading to connector 16 (3) and then to connector 16 (19); 'Forward-transfer' leading to state FITE 23 and then to connector 22 (4); and 'Clear-forward' leading to connector 19 (4).

It branches into nine parallel input paths: SAM, BITE 30, BITE 2, BITE 3, BITE 4, BITE 5, BITE 6, BITE 7, and CLF. The SAM path involves stopping t2, checking for ST received and CCSS, starting t2 or t3, and sending FITE 1. The BITE paths involve various tasks like ADC, ADN, ADX, AFC, AFN, AFX, stopping timers t2 and t3, and deactivating/setting up speech paths (SPITE 3/4). The CLF path sends FITE 22 and stops timers.

+![Flowchart for Incoming Signalling System No. 6, Figure 3/Q.613 (Sheet 6 of 8).](f4fdd410cdb84df81274da55721e56fb_img.jpg)
+
+The flowchart illustrates the logic for Incoming Signalling System No. 6. It begins with a connector reference 'B' and a list of input conditions: BITE 9 (SEC), BITE 10 (CGC), BITE 12 (NNC), BITE 14 (ADI), BITE 15 (UNN), BITE 16 (SSB), BITE 17 (LOS), BITE 19 (CFL), and BITE 20 (SST). These inputs feed into a decision block 'Is speech path set up'. If 'No', it proceeds to 'SPITE 5 Release speech conditions' and then 'Stop t2'. If 'Yes', it proceeds to 'SPITE 3 Deactivate register function'. From 'SPITE 3', the flow goes to connector '28' (labeled '07 Wait for register deactivation').
+
+From connector '28', the flowchart branches based on BITE 27, BITE 10 (CGC), BITE 12 (NNC), BITE 19 (CFL), and CLF. BITE 27 leads to connector '15'. BITE 10 and BITE 12 lead to a decision 'Is speech path set up'. If 'No', it goes to 'SPITE 5 Release speech conditions' and then 'SPITE 3 Deactivate register function', leading to connector '5'. If 'Yes', it goes to 'Start t4'. BITE 19 (CFL) leads to connector '6'. CLF leads to 'FITE 22' and then connector '6'.
+
+From 'Start t4' (with a duration of t4 = 4 - 15 s), the flow goes to '10 Call unsuccessful wait for clear-forward'. From there, it branches based on CLF,  $\bar{t}_4$ , and CFL. CLF leads to 'Stop t4' and then connector '19'.  $\bar{t}_4$  leads to 'CFL' and then 'Start t5' (with a duration of t5 = 1 min.), leading to connector '20'. CFL leads to connector '19'.
+
+Another 'Start t4' block is shown, leading to '18 Call fail wait for clear-forward'. This block branches based on CLF,  $\bar{t}_4$ , and  $\bar{t}_5$ . CLF leads to 'Stop t4' and then 'Stop t5', leading to connector '19'.  $\bar{t}_4$  leads to 'CFL' and then connector '20'.  $\bar{t}_5$  leads to 'Stop t4' and then connector 'P2', which is labeled 'Out of service'.
+
+Other connectors and labels include '4, 5' at the top left, '28' at the top, '15', '19', '6', '20', '5', '6', '19', '20', '19', '20' at the bottom, and 'CCITT-t0822' at the bottom right.

+
+## FOREWORD
+
+The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+ITU-T Recommendation Q.627 was prepared by the ITU-T Study Group XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993).
+
+## --- NOTES
+
+1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T) was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the IFRB have been replaced by the Radiocommunication Sector.
+
+In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms "CCITT, CCIR or IFRB" or their associated entities such as Plenary Assembly, Secretariat, etc. Future editions of this Recommendation will contain the proper terminology related to the new ITU structure.
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+
+The flowchart illustrates the logic for Outgoing Signalling System No. 7 (ISUP). It begins at the top with state 3 (labeled 1, 2(3x)). The process enters a loop labeled '02 Wait for continuity check'. From this loop, five parallel paths emerge, each leading to a different state or condition:
+
+- SPITE 33 Continuity check OK** leads to state 3 (labeled C).
+- FITE 1** leads to a decision diamond **SAM Complete?**.
+  - If **No**, it leads to state 3 (labeled 2).
+  - If **Yes**, it leads to **Start t<sub>2</sub>**, then **SAM** (with a **Note**), and finally to state 3 (labeled 2).
+- FITE Z** leads to **SPITE 54**, then **Stop t<sub>1</sub>**, then **Stop t<sub>2</sub>**, and finally to state 12 (labeled 8).
+- FITE 24** leads directly to state 3 (labeled 2).
+- t<sub>1</sub>** leads directly to state P<sub>1</sub>.
+
+From the **SPITE 33 Continuity check OK** path, the flow continues to **Stop t<sub>1</sub>** (labeled 3, P<sub>1</sub> (2x)). From **Stop t<sub>1</sub>**, the flow leads to a decision diamond **Cross office check?**.
+ 
+
+- If **No**, it leads to state 1 (labeled 1).
+- If **Yes**, it leads to a decision diamond **CCH?**.
+  - If **0**, it leads to state P<sub>2</sub>.
+  - If **1, 2**, it leads to state 9 (labeled 3).
+
+ From state 9 (labeled 3), the flow leads to a decision diamond **FITE 24 received?**.
+

+The flowchart illustrates the logic for Outgoing Signalling System No. 7 (ISUP). It begins with a start node 'C' (circle), which leads via an arrow labeled '2, 3, 5' to a process block 'REL' (parallelogram). This is followed by a decision block 'BITE Z' (pentagon pointing left). The next step is a process block 'Stop t<sub>2</sub>' (pentagon pointing left). A decision block 'CCH' (diamond) follows. If the result is '0, 2', the flow proceeds to a junction point. If the result is '1', the flow proceeds to a decision block 'Cont. check OK?' (diamond). If 'Yes', it proceeds to the junction point. If 'No', it proceeds to a process block 'Stop t<sub>1</sub>' (pentagon pointing left), which then leads to the junction point. From the junction point, the flow proceeds to an end node '10' (circle). The number '10' is also written to the left of the end node, and the number '8' is written below it. The identifier 'T1141400-92/d05' is located at the bottom right of the diagram.

+
+The flowchart illustrates the logic for Outgoing Signalling System No. 7 (ISUP). It begins at the top with a circle containing '3, 5(x2)' and '5'. An arrow points down to a rounded rectangle labeled '04 Wait for address complete'. From here, the path splits into several branches:
+
+- Left branch:** From '04 Wait for address complete', an arrow points down to a parallelogram labeled 'ACM'. Below it is a diamond labeled 'BITE X', then a chevron labeled 'Stop t<sub>2</sub>'. This leads to a circle containing '6' and '5'. From this circle, an arrow labeled '(x2)' points to a rounded rectangle labeled '05 Wait for answer'. Below '05 Wait for answer' is a parallelogram labeled 'ANM', then a diamond labeled 'BITE Y', which leads to a circle containing '8' and '6'.
+- Central branch:** From '04 Wait for address complete', an arrow points to a parallelogram labeled 'FITE 1'. Below it is a decision diamond labeled 'SAM complete?'. If 'No', it leads to a circle containing '5'. If 'Yes', it leads to a chevron labeled 'Start t<sub>2</sub>', then a parallelogram labeled 'SAM'. A dashed line from 'SAM' points to a 'Note'. Below 'SAM' is a circle containing '5' and '5'.
+- Right branches:**
+  - From 'FITE 1', an arrow points to a parallelogram labeled 'FITE Z', then a chevron labeled 'Stop t<sub>2</sub>', then a rectangle labeled 'SPITE 54', which leads to a circle containing '12' and '8'.
+  - From 'FITE Z', an arrow points to a double-lined parallelogram labeled 't<sub>2</sub>', then a diamond labeled 'BITE Z', then a rectangle labeled 'SPITE 54 Cause 31', which also leads to the circle containing '12' and '8'.
+  - From 't<sub>2</sub>', an arrow points to a parallelogram labeled 'CON', then a chevron labeled 'Stop t<sub>2</sub>', then a diamond labeled 'BITE 48', which leads to a circle containing '8' and '6'.
+- Bottom branches:** From the circle containing '5' and '5' (below 'SAM'), an arrow points to a horizontal line. From this line, five branches descend:
+  - Parallelogram 'REL' → diamond 'BITE Z' → circle '10' and '8'.
+  - Parallelogram 'BITE 47' → diamond 'BITE 47' → circle '6' and '5'.
+  - Parallelogram 'FITE 23' → diamond 'FOT' → circle '6' and '5'.
+  - Parallelogram 'FITE Z' → rectangle 'SPITE 54' → circle '12' and '8'.
+
+On the far left, a vertical line has labels '5', 'C', '12, 8', '6', '5', '8, 10, 6, 6, 12'. On the far right, a circle labeled 'C' and '4' is connected to the top horizontal line. A 'Note' is indicated by a dashed line from the 'SAM' parallelogram. The bottom right corner contains the text 'T1141410-92/d06'.

+The diagram illustrates the flow of signalling messages in an Outgoing Signalling System No. 7 (ISUP). It begins with a circle labeled '8' at the top left, with an arrow pointing down to a box labeled '07 Answered'. Above this arrow is the text '5(x2), 6, 7'. From the 'Answered' box, a horizontal line extends to the right, with a circle labeled 'H' at its end. Below this line, four boxes are arranged horizontally: 'REL', 'FITE 23', 'FITE 34', and 'FITE 35'. Each of these boxes has a downward-pointing arrow to a corresponding box below it: 'BITE Z', 'FOT', 'SUS (User)', and 'RES (User)'. Below 'BITE Z' is a circle labeled '10' with the number '8' below it. Below 'FOT' is a circle labeled '8' with the number '6' below it. Below 'SUS (User)' and 'RES (User)' is a horizontal line with an arrow pointing left to the 'FOT' box. To the right of this line is the text 'T1141420-92/d07'. On the far left, there are vertical labels '8', 'H', and '10, 8'.

+
+## FOREWORD
+
+The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+ITU-T Recommendation Q.656 was prepared by the ITU-T Study Group XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993).
+
+## --- NOTES
+
+1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T) was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the IFRB have been replaced by the Radiocommunication Sector.
+
+In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms "CCITT, CCIR or IFRB" or their associated entities such as Plenary Assembly, Secretariat, etc. Future editions of this Recommendation will contain the proper terminology related to the new ITU structure.
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+
+The diagram illustrates the interworking of Signalling System No. 6 to Signalling System No. 7 (ISUP). It features four vertical paths originating from a common horizontal line at the top, which is marked with a circled '2' and a subscript '2'.
+
+- Path 1 (Leftmost):** Passes through a chevron-shaped block labeled 'BITE X', then a rectangular block labeled 'SPITE 53 (Table 2)', then a chevron-shaped block labeled 'BITE n', and finally terminates at a circled '3' with a subscript '4'.
+- Path 2:** Passes through a chevron-shaped block labeled 'BITE 30', then a chevron-shaped block labeled 'BITE 30', and terminates at a circled '1' with a subscript '2'.
+- Path 3:** Passes through a chevron-shaped block labeled 'BITE Z', then a rectangular block labeled 'SPITE 53 (Table 5)', then a chevron-shaped block labeled 'BITE n', then a double-lined oval block labeled '00 Idle', and finally terminates at a circled '4' with a subscript '4'.
+- Path 4 (Rightmost):** Passes through a chevron-shaped block labeled 'BITE 48', then a rectangular block labeled 'SPITE 53 (Table 4)', then a chevron-shaped block labeled 'BITE j', then a chevron-shaped block labeled 'BITE k', and finally terminates at a circled '4' with a subscript '4'.
+
+On the left side of the diagram, there are vertical labels: '2' at the top, '1' in the middle, and '3, 4' at the bottom, corresponding to the levels of the various blocks.

+
+The diagram illustrates the interworking of Signalling System No. 6 to Signalling System No. 7 (ISUP). It is divided into two horizontal sections.
+
+**Top Section:** At the top, a circle containing the number '5' with a subscript '4' points down to a horizontal line. Below this line are four chevron-shaped boxes: 'BITE Z', 'FITE 22', 'FITE 23', and 'BITE 25'. Below 'BITE Z' is a parallelogram 'BITE 25'. Below 'FITE 22' is a parallelogram 'FITE Z'. Below 'FITE 23' is a parallelogram 'FITE 23'. Below 'BITE 25' is a parallelogram 'BITE 25'. A bracket labeled '(Note)' is next to the 'BITE 25' parallelogram. Arrows from 'BITE 25' (parallelogram), 'FITE 23' (parallelogram), and 'BITE 25' (parallelogram) point to terminal states: '00 Idle', a circle with '4' and subscript '4', and '05 Wait for resume' respectively. A circle with '6' and subscript '5' points to the arrow leading to '05 Wait for resume'.
+
+**Bottom Section:** Below the top section, another horizontal line connects to four chevron-shaped boxes: 'FITE 22', 'FITE 23', 'BITE 24', and 'BITE Z'. Below 'FITE 22' is a parallelogram 'FITE Z' with a bracket labeled '(Note)' next to it. Below 'FITE 23' is a parallelogram 'FITE 23'. Below 'BITE 24' is a parallelogram 'BITE 24'. Below 'BITE Z' is a terminal state '00 Idle'. Arrows from 'FITE Z' (parallelogram), 'FITE 23' (parallelogram), and 'BITE 24' (parallelogram) point to terminal states: '00 Idle', a circle with '6' and subscript '5', and a circle with '4' and subscript '4' respectively. The text 'T1125000-90/d06' is in the bottom right corner.
+
+On the far left, vertical labels '5', '6', '4', and '6, 4' are present.

+The diagram is a flowchart representing the interworking between Signalling System No. 7 (TUP) and Signalling System No. 6. It consists of several states and transitions:
+
+- State 00 (Idle):** Leads to a task 'Activate I/W No. 7 (TUP)/No. 6'.
+- State 01 (Wait for CPCI-FITE):** Follows the activation task. It has multiple output paths based on received signals like FITEs 9-13, 17-19, and FITE 30.
+- State 02 (Wait for address complete):** Entered from connector 1. It handles various BITE (Backward Interworking Telephony Event) and FITE (Forward Interworking Telephony Event) signals.
+- State 03 (Wait for answer):** Entered from connector 2. It handles BITE 22, BITE 23, BITEs 10, 12, 19, FITE 22, and FITE 23.
+- Decision Points:** Includes checks for 'Country code FITE', 'SPITE 22', 'SPITE 21', and 'SPITE 20'.
+- Connectors:** Circular markers labeled 1, 2, 3, 4, and A are used to link different parts of the flowchart across the page and potentially to other sheets.

+The diagram illustrates the interworking of Signalling System No. 7 (TUP) to No. 6. It is divided into two main sections.
+
+**Left Section (Connector reference A, 3, P1, 4, 3, 4, 3):**
+
+- Starts with a call attempt (3) leading to an **Answered** state (04).
+- From **Answered**, three paths are possible:
+  - BITE 25** leads to another **BITE 25** state, which then leads to a **Clear-back** state (05).
+  - FITE 22** leads to another **FITE 22** state, which then leads to an **Idle** state (00).
+  - FITE 23** leads to another **FITE 23** state, which then leads to a call termination (3).
+- From **Clear-back** (05), three paths are possible:
+  - FITE 22** leads to another **FITE 22** state, which then leads to an **Idle** state (00).
+  - FITE 23** leads to another **FITE 23** state, which then leads to a call termination (4).
+  - BITE 24** leads to another **BITE 24** state, which then leads to a call termination (3).
+- From **Idle** (00), the path leads to a call termination (4).
+
+**Right Section (Connector reference A):**
+
+- Starts with a call attempt (1) leading to a series of message states: **BITE 12**, **BITE 14**, **BITE 15**, **BITE 16**, **BITE 17**, **BITE 20**, and **BITEs 9, 10, 19**.
+- Each message state has a corresponding return message state: **BITE 12**, **BITE 14**, **BITE 15**, **BITE 16**, **BITE 17**, **BITE 20**, and **BITEs 9, 10, 19**.
+- From the return message states, the flow leads to a decision diamond: **Repeat attempt**.
+- If **Yes**, it leads to a **Repeat attempt procedure** (P1), which loops back to the initial message states.
+- If **No**, it leads to a decision diamond: **Which BITE**.
+- From **Which BITE**, three paths are possible based on connector references 9, 10, and 19:
+  - BITE 9** leads to an **Idle** state (00).
+  - BITE 10** leads to an **Idle** state (00).
+  - BITE 19** leads to an **Idle** state (00).

+# NOTES
+
+1 ITU-T Recommendation Q.702 was published in Fascicle VI.7 of the *Blue Book*. This file is an extract from the *Blue Book*. While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+# SIGNALLING DATA LINK
+
+## 1 General
+
+1.1 A *signalling data link* is a bidirectional transmission path for signalling, comprising two *data channels* operating together in opposite directions at the same data rate. It constitutes the lowest functional level (level 1) in the Signalling System No. 7 functional hierarchy.
+
+1.2 Functional configuration of a signalling data link is shown in Figure 1/Q.702.
+
+1.3 A digital signalling data link is made up of digital *transmission channels*<sup>1)</sup> and digital switches or their terminating equipment providing an interface to signalling terminals. The digital transmission channels may be derived from a digital multiplex signal at 1544, 2048 or 8448 kbit/s having a frame structure as defined in Recommendation G.704 [1], or from digital multiplex streams having a frame structure specified for data circuits (Recommendations X.50 [4], X.51 [5], X.50 bis [6], X.51 bis [7]).
+
+1.4 An analogue signalling data link is made up of voice-frequency analogue transmission channels either 4 kHz or 3 kHz spaced, and modems.
+
+1.5 Signalling System No. 7 is capable of operating over both terrestrial and satellite *transmission links*<sup>1)</sup>.
+
+---
+
+1) The terms *transmission channel* and *transmission link* are used in Signalling System No. 7 instead of transfer channel and transfer link used in Signalling System No. 6.

+Functional configuration of a signalling data link
+
+1.6 The operational signalling data link shall be exclusively dedicated to the use of a Signalling System No. 7 signalling link between two signalling points. No other information should be carried by the same channel together with the signalling information.
+
+1.7 Equipment such as echo suppressors, digital pads, or A/μ law convertors attached to the transmission link must be disabled in order to assure full duplex operation and bit integrity of the transmitted data stream.
+
+1.8 64-kbit/s digital signalling channels entering a digital exchange via a multiplex structure shall be switchable as semi-permanent channels in the exchange.
+
+## 2 Signalling bit rate
+
+### 2.1 General
+
+2.1.1 The standard bit rate on a digital bearer will be 64 kbit/s.
+
+2.1.2 Lower bit rates may be adopted for each application, taking into account the User Part requirements and the capability of available transmission links.
+
+2.1.3 The minimum signalling bit rate for telephone call control applications will be 4.8 kbit/s. For other applications such as network management, bit rates lower than 4.8 kbit/s can also be used.
+
+### 2.2 *Use of bit rates lower than 64 kbit/s*
+
+2.2.1 For national telephone call control applications, use of Signalling System No. 7 at bit rates lower than 64 kbit/s shall take account of the requirement to minimize the answer signal delay when in-band line signalling systems are involved (Recommendation Q.27 [8]).
+
+2.2.2 Signalling System No. 7 can be used for direct international application at bit rates lower than 64 kbit/s between countries which have no in-band line signalling systems in their national extension networks (see § 2.1.3).
+
+2.2.3 The possible use of Signalling System No. 7 at bit rates lower than 64 kbit/s between countries which have in-band line signalling systems in their national extension networks is for further study.
+
+## 3 **Error characteristics and availability**
+
+Error characteristics and availability requirements will conform to relevant Recommendations (for example, Recommendation G.821 [9] on digital circuits). No additional characteristics or requirements will be specified in this Recommendation.
+
+## 4 **Interface specification points**
+
+4.1 Interface requirements may be specified at one of three points, A, B or C in Figure 2/Q.702. The appropriate point depends on the nature of transmission links used and the approach toward the implementation of interface equipment adopted by each Administration.
+
+4.2 For the international application, interface requirements at either Point B or Point C will apply.
+
+4.3 Interface requirements for an international digital signalling data link will be specified at Point C in accordance with the specific multiplex structure used (see § 5.)
+
+4.4 Interface requirements for an international analogue signalling data link will be specified at Point B on a single channel basis, and thus are independent of multiplex equipment used. (See § 6.)
+
+4.5 Interface at Point A may or may not appear in particular implementations, as each Administration may adopt different approaches towards the implementation of interface equipment. If it does appear in implementations, then the interface requirements specified in Recommendations V.10 [10], V.11 [11], V.24 [12], V.28 [13], V.35 [14], V.36 [15], X.24 [16] and G.703 [17] (for 64-kbit/s interface) should be followed as appropriate.
+
+4.6 Implementations which do not follow all the requirements in the relevant Recommendations cited above should nevertheless take into account those requirements that are specified for testing and maintenance actions which require communication between the two ends of a data link. Interface requirements for testing and maintenance are specified in Recommendation Q.707.

+## 5 Digital signalling data link
+
+### 5.1 Signalling data link derived from the 2048-kbit/s digital path
+
+When a signalling data link is to be derived from a 2048-kbit/s digital path, the following shall apply:
+
+- The interface requirements, specified at Point C in Figure 2/Q.702, should comply with Recommendations G.703 [17] for the electrical characteristics and G.704 [1] for the functional characteristics, in particular the frame structure.
+- The signalling bit rate shall be 64 kbit/s.
+- The standard channel time slot for the use of a signalling data link is time slot 16. When time slot 16 is not available, any channel time slot available for 64-kbit/s user transmission may be used.
+- No bit inversion is performed.
+
+### 5.2 Signalling data link derived from the 8448-kbit/s digital path
+
+When a signalling data link is to be derived from a 8448-kbit/s digital link, the following shall apply:
+
+- The interface requirements, specified at Point C in Figure 2/Q.702, should comply with Recommendations G.703 [23] for the electrical characteristics and G.704 [1] for the functional characteristics, in particular the frame structure.
+- The signalling bit rate shall be 64 kbit/s.
+- The standard channel time slots for the use of a signalling data link are time slots 67 to 70 in descending order of priority. When they are not available, any channel time slot available for 64-kbit/s user transmission may be used.
+- No bit inversion is performed.
+
+### 5.3 *Signalling data link derived from the 1544-kbit/s digital path*
+
+(For further study.)
+
+*Note* - When a signalling bit rate of 64 kbit/s is adopted, the values of bits should be inverted within the signalling terminal or the interface equipment in order to meet the minimum mark density requirements of the Recommendation G.733 [2] based PCM systems.
+
+### 5.4 *Signalling data link established over a digital path made up by digital sections based on different digital hierarchies*
+
+When a signalling data link is to be established between networks based on different digital hierarchies and speech encoding laws, the following shall apply:
+
+- a) The interface requirements, specified at Point C in Figure 2/Q.702, should comply with Recommendations G.703 [17] for the electrical characteristics and G.802 [3] for other aspects, e.g., for interworking arrangements.
+- b) The signalling bit rate shall be 64 kbit/s.
+- c) No bit inversion is performed.
+
+### 5.5 *Signalling data link established over data circuits*
+
+When a signalling data link is to be established over data circuits derived from a 64-kbit/s digital stream having a frame structure as specified in such Recommendations as X.50 [10], X.51 [11], X.50 *bis* [12] and X.51 *bis* [13] the following shall apply:
+
+- a) The interface requirements, specified at Point C in Figure 2/Q.702, should comply with relevant requirements in one of the above-mentioned Recommendations, applicable to the environment of the intended use.
+- b) When 64-kbit/s multiplexed streams are carried on 2048-kbit/s or 1544-kbit/s digital links, Recommendation G.704 [1], should apply
+
+## 6 **Analogue signalling data link**
+
+### 6.1 *Signalling bit rate*
+
+6.1.1 Applications of the analogue signalling data link must take account of the delay requirements described in § 2.2.
+
+6.1.2 For telephone call control applications, the signalling bit rate over an analogue signalling data link shall be higher or equal to 4.8 kbit/s.
+
+### 6.2 *Interface requirements*
+
+In case of 4.8-kbit/s operation, interface requirements specified at the interface point B in Figure 2/Q.702 should comply with relevant requirements specified for 4.8-kbit/s modems in Recommendations V.27 [18] and V.27 *bis* [19]. In addition, the following shall apply:
+
+- a) Application of either Recommendations V.27 [18] or V.27 *bis* [19] depends on the quality of the analogue transmission channels used. Recommendation V.27 [18] shall apply only to transmission channels conforming to Recommendation M.1020 [20], while Recommendation V.27 *bis* [19] to transmission channels conforming to Recommendation M.1020 [20] or of lower quality.
+- b) Full duplex operation over a 4-wire transmission link should be adopted.
+- c) If a separate modem is to be used, the interface requirements specified in Recommendations V.10 [10], V.11 [11], V.24 [12] and V.28 [13], applicable at Point A in Figure 2/Q.702, should be followed as much as possible.

+# NOTES
+
+1 ITU-T Recommendation Q.710 was published in Fascicle VI.7 of the *Blue Book*. This file is an extract from the *Blue Book*. While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).
+
+2 In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+# **SIMPLIFIED MTP VERSION FOR SMALL SYSTEMS**
+
+## **1 Field of application**
+
+1.1 This Recommendation is applicable for systems using a simplified MTP version to interface to the public network(s).
+
+1.2 The MTP functions specified in § 3 of this Recommendation may be applied in general for small systems, e.g., PABX's, remote concentrators, etc., interfacing with the message transfer part described in Recommendations Q.702, Q.703, Q.704 and Q.707.
+
+1.3 The Recommendation applies only for digital access arrangements.
+
+1.3.1 In case one channel carries signalling information for more than one multiplex system, at least one additional channel should be pre-assigned as a stand-by signalling link in a multiplex system other than that which contains the active channel. This allows the changeover and changeback procedures specified in §§ 3.4.4 and 3.4.5 to be performed.
+
+1.3.2 The stand-by channel(s) should not be used as B-channel(s).
+
+1.4 Only the associated mode of signalling is applicable.
+
+1.5 A variety of information types may be supported by the signalling system, e.g., relating to circuit switched call control and packet communication.
+
+## **2 Functional content**
+
+The functional requirements are as follows:
+
+2.1 The network call control functions are as specified in Recommendation Q.930 (I.451).
+
+*Note* - Different network layer protocols (circuit switching and packet switching) may be supported by using the protocol discriminator included in Recommendation Q.930. As an alternative, different network layer entities may access the interface functions directly. In that case, the interface functions will use separate service indicator codes to discriminate the applicable network layer entity. This will be similar to the use of SAPI specified in Recommendation Q.920. Which principle to be applied is determined by the Administration/RPOA.
+
+2.2 The minimum set of Message Transfer Part functions are specified in Recommendations Q.702, Q.703, Q.704 and Q.707, with the qualifications specified in § 3 of this Recommendation.
+
+2.3 The additional interface functions required for the proper operation of the D-channel call control functions in combination with the message transfer part functions, are specified in § 4 of this Recommendation (see Figure 1/Q.710).

+## 3 Message Transfer Part (MTP) functions
+
+### 3.1 General
+
+The MTP functions as specified in Recommendations Q.702, Q.703, Q.704 and Q.707 are applicable. However, the following exceptions and modifications to those Recommendations may be applied for the PABX system, see §§ 3.2-3.4.
+
+In order to prevent fraudulent use of the signalling network, it has to be ensured that no signalling messages generated by a PABX can be routed further than the public exchange to which the PABX has access. The manner in which this is made may be dependent on national circumstances and system implementations. An example of how such a function could be implemented is given in § 3.5.
+
+### 3.2 Level 1 (Recommendation Q.702)
+
+Only digital signalling data links are relevant. Recommendation Q.702, § 6, is not applicable.
+
+### 3.3 Level 2 (Recommendation Q.703)
+
+#### 3.3.1 Initial alignment procedure (Recommendation Q.703, § 7)
+
+In the initial alignment procedure specified in Recommendation Q.703, § 7, only the emergency proving is applicable. Thus, in states "aligned" and "proving" of the initial alignment procedure status indication "N" is not sent.
+
+#### 3.3.2 Processor outage (Recommendation Q.703, § 8)
+
+The processor outage function specified in Recommendation Q.703, § 8, is not applicable.
+
+When the level 2 function receives an indication that a processor outage situation exists at the remote and (through the reception of status signal units indicating processor outage), it transmits status signal units indicating "out of service".
+
+#### 3.3.3 *Flow control* (Recommendation Q.703, § 9)
+
+The sending of the link status indication "B" from the PABX is not applicable.

+
+The message retrieval procedure defined in § 5.5 is not applicable.
+
+Diversion of traffic is performed at expiry of a time-out T1 (c.f. Recommendation Q.704, § 16.8) is started when the changeover is initiated.
+
+#### 3.4.5 *Changeback* (Recommendation Q.704, § 6)
+
+Changeback between link sets is not applicable.
+
+The sequence control procedure defined in § 6.3 is not applicable. At reception of a changeback declaration, a changeback acknowledgement is sent in response.
+
+For the purpose of ensuring message sequence integrity, the time controlled diversion procedure specified in § 6.4 is used.
+
+#### 3.4.6 *Forced rerouting* (Recommendation Q.704, § 7)
+
+Forced rerouting is not applicable.
+
+#### 3.4.7 *Controlled rerouting* (Recommendation Q.704, § 8)
+
+Controlled rerouting is not applicable.

+
+#### 3.4.10 *Signalling traffic flow control* (Recommendation Q.704, § 11)
+
+Signalling route set congestion (Recommendation Q.704, § 11.2.3) is not applicable.
+
+MTP User flow control (Recommendation Q.704, § 11.2.7) is not applicable.
+
+#### 3.4.11 *Signalling link management* (Recommendation Q.704, § 12.2)
+
+Only basic link management procedures are applicable.
+
+#### 3.4.12 *Link set activation* (Recommendation Q.704, § 12.2.4)
+
+Link set normal activation defined in § 12.2.4.1 is not applicable.
+
+Link set emergency restart is used in all cases.
+
+#### 3.4.13 *Transfer prohibited* (Recommendation Q.704, § 13.2)
+
+The transfer prohibited function is not applicable. At the reception of a TFP message, no action should be taken.
+
+#### 3.4.14 *Transfer allowed* (Recommendation Q.704, § 13.3)
+
+The transfer allowed function is not applicable. At the reception of a TFA-message, no action should be taken.
+
+#### 3.4.15 *Transfer restricted* (Recommendation Q.704, § 13.4)
+
+The transfer restricted function is not applicable for the PABX. At the reception of the TFR message no action is taken by the PABX.
+
+#### 3.4.16 *Signalling-route-set-test* (Recommendation Q.704, § 13.5)
+
+The signalling-route-set-test procedure is not applicable.
+
+#### 3.4.17 *Transfer controlled* (Recommendation Q.704, §§ 13.7, 13.8)
+
+The transfer controlled function is not applicable for the PABX. At the reception of the TFC message, no action is taken by PABX.

+
+The signalling route-set-congestion-test function is not applicable for the PABX.
+
+At the reception of signalling-route-set-congestion-test message no action is taken by the PABX.
+
+#### 3.4.19 *Signalling link test* (Recommendation Q.707, § 2.2)
+
+The ability to respond to a signalling link test message with a signalling link test acknowledge message must always be provided by the PABX.
+
+### 3.5 *Example of "Screening Function"*
+
+*Note* - This paragraph is provided for illustration purposes only.
+
+At an exchange (which has the capability of acting as an STP) each message received on a PABX access link is
+
+passed through a "screening function" that checks that the DPC of the message is the same as the SP code of the exchange. If that is the case, the message is sent to the normal MTP message handling functions. Otherwise, the message is discarded.
+
+## 4 Interface functions
+
+### 4.1 General
+
+The task of the interface functions is to provide the layer-to-layer interfaces according to what is specified in Recommendations Q.920, Q.930 on the one hand and in Recommendation Q.704 on the other, see the Figure 2/Q.710. This will include some conversion functions which are specified in § 4.4.
+
+![Diagram of Figure 2/Q.710 showing the interaction between three entities: D-CHANNEL NETWORK LAYER ENTITY (Q.930), INTERFACE ENTITY (Q.710), and MESSAGE TRANSFER PART - LEVEL 3 (Q.704).](49ee89a1d5852ab005dbbab6de09a8a6_img.jpg)
+
+The diagram illustrates the interaction between three entities in a layered protocol structure. At the top is the **D-CHANNEL NETWORK LAYER ENTITY (Q.930)**. Below it is the **INTERFACE ENTITY (Q.710)**. At the bottom is the **MESSAGE TRANSFER PART - LEVEL 3 (Q.704)**. Vertical arrows indicate bidirectional communication between adjacent entities. A dashed horizontal line separates the top entity from the middle one, labeled "Layer-to-layer interface specified in Recommendations Q.920, Q.930". Another dashed horizontal line separates the middle entity from the bottom one, labeled "Layer-to-layer interface specified in Recommendation Q.704". The code "CCITT-72970" is located at the bottom right of the diagram.

+
+FIGURE 2/Q.710
+
+### 4.2 Interactions with the network layer entity (Q.930)
+
+The layer-to-layer interactions between the network layer and the data link layer of the D-channel protocol are specified in Recommendation Q.920, § 4. The interactions are specified in the form of primitives. The primitive applicable for the primary rate interface structure are:
+
+DL-DATA-REQUEST/INDICATION
+
+The DL-DATA-REQUEST primitive is used to request that a network layer message unit be sent. The
+
+DL-DATA-INDICATION indicates the arrival of a message unit.
+
+### 4.3 *Interactions with the message transfer part*
+
+The layer-to-layer interactions between the MTP and the User Parts of Signalling System No. 7 are specified in Recommendations Q.701 and Q.704, Figures 23/Q.704 and 27/Q.704.
+
+The following primitives are used:
+
+- a) MTP-TRANSFER (see Recommendation Q.701, § 8.1),
+- b) MTP-PAUSE (see Recommendation Q.701, § 8.2),
+- c) MTP-RESUME (see Recommendation Q.701, § 8.3).
+
+### 4.4 *Conversion functions*
+
+The Table 1/Q.710 shows the association between the D-channel primitives and the Signalling System No. 7 interactions.
+
+TABLE 1/Q.710
+
+|                      | D-channel | SS No. 7                               |
+|----------------------|-----------|----------------------------------------|
+| Information transfer | DL-DATA   | MTP-TRANSFER                           |
+| Flow control         | -<br>-    | MTP-PAUSE (STOP)<br>MTP-RESUME (START) |
+
+#### 4.4.1 *Information transfer*
+
+When receiving a DL-DATA-REQUEST primitive from the network layer entity, the interface entity generates a MTP-TRANSFER Request primitive which contains:
+
+- The message unit associated with the primitive.
+- A label consisting of DPC, OPC and SLS. The label is generated by the interface entity on the basis of information regarding the destination of the message. The SLS is coded 0000.
+
+*Note* - In some implementations where the label is not used for routing purposes, the entire label may be coded "all zeros".
+
+- A service information octet (SIO) is generated by the interface entity in accordance with a predetermined rule and, as a national option, on the basis of priority information associated with the primitive. The NI is coded 10 or 11. The SI code is determined by the Administration or RPOA.
+
+*Note* - In the case when the interface functions provide direct access to more than one network layer entity, the SI code will depend on the network layer entity to which the message is associated.
+
+When receiving a MTP-TRANSFER Indication from the MTP, the interface entity sends a DL-DATA-INDICATION primitive to the network layer entity.
+
+#### 4.4.2 *Flow control*
+
+When receiving a MTP-PAUSE indication from the MTP, the interface entity will generate a DL-PAUSE-INDICATION primitive to the network layer entity.
+
+When receiving a MTP-RESUME indication from the MTP, the interface entity will generate a DL-RESUME-INDICATION primitive to the network layer entity.

+# **Functional description of the signalling connection control part**
+
+# **Summary**
+
+The Q.71X-series Recommendations defines the services of the SCCP. The SCCP is part of SS No. 7 and provides, above the MTP network or networks, connectionless, connection-oriented, routing and management services.
+
+## **Source**
+
+ITU-T Recommendation Q.711 was revised by ITU-T Study Group 11 (2001-2004) and approved under the WTSA Resolution 1 procedure on 1 March 2001.
+
+# FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# **Functional description of the signalling connection control part**
+
+# **1 Scope and field of application**
+
+The Signalling Connection Control Part (SCCP) provides additional functions to the Message Transfer Part (MTP) to cater for both connectionless as well as connection-oriented network services to transfer circuit-related and non-circuit-related signalling information and other types of information between exchanges and specialized centres in telecommunication networks (e.g. for management and maintenance purposes) via a Signalling System No. 7 network.
+
+A functional block above the message transfer part performs the functions and procedures of the SCCP. The SCCP is capable of using the services of the MTP as described in ITU-T Q.701 to ITU-T Q.707, and/or in ITU-T Q.2210. The combination of the MTP and the SCCP is called "network service part" (NSP).
+
+The network service part follows the principles of the OSI-reference model as defined in ITU-T X.200, providing a subset of the layer 3 services defined in ITU-T X.213.
+
+It is the intent of ITU-T Q.711, ITU-T Q.712, ITU-T Q.713 and ITU-T Q.714 to specify protocol entities which perform the functions according to the SCCP of the Signalling System No. 7. These protocol entities conform at their lower boundary to the upper boundary conditions specified in ITU-T Q.704 or ITU-T Q.2210 for use of the service offered by the underlying layers.
+
+The SCCP making use of the services of the MTP, as specified in ITU-T Q.2210, provides the connectionless network service as specified in this Recommendation. A connection-oriented network service can only use the services which are common to ITU-T Q.2210 and ITU-T Q.704 for the MTP.
+
+ITU-T Q.715 gives guidance on a number of specific issues related to the incorporation of SCCP in actual networks. These guidelines are in their entirety informal and do not specify any requirement.
+
+The SCCP congestion control procedures may be subject to improvement pending further analysis of the impact of these procedures in different network scenarios and based on the results of operational experience. The overall objectives of the signalling connection control part are to provide the means for:
+
+- a) logical signalling connections within the Signalling System No. 7 network;
+- b) a transfer capability for network service data units with or without the use of logical signalling connections.
+
+Functions of the SCCP are also used for the transfer of circuit-related and call-related signalling information of the ISDN user part with or without setup of end-to-end logical signalling connections. These functions are described in ITU-T Q.714 and ITU-T Q.730. Figure 1 illustrates the embedding of the SCCP within the Signalling System No. 7.

+
+## 5.1 Technique of description
+
+The Signalling Connection Control Part (SCCP) is described in terms of:
+
+- services provided by the SCCP;
+- services assumed from the MTP;
+- functions of the SCCP.
+
+The functions of the SCCP are performed by means of the SCCP protocol between two systems that provide the NSP service to the upper layers.
+
+The service interfaces to the upper layers and to the MTP are described by means of primitives and parameters, as recommended in ITU-T X.200. Figure 2 illustrates the relationship between the SCCP protocol specification and the definition of adjacent services.
+
+![Figure 2/Q.711 – Relationship between the SCCP protocol specification and the definition of adjacent services. The diagram shows a box on the left labeled 'SCCP protocol specification'. To its right are two boxes: 'Network service definition' at the top and 'MTP service definition' at the bottom. Solid arrows point from the SCCP specification box to both service definition boxes. Dashed lines between the SCCP specification and the service definitions are labeled 'Reference to aims' and 'Reference to assumptions'.

+
+This diagram shows the points at which service primitives are invoked. It is not intended to constrain the architecture. For the architectural considerations, some information is provided in ITU-T Q.1400.
+
+## 5.3 Peer-to-peer communication
+
+Exchange of information between two peers of the SCCP is performed by means of a protocol. The protocol is a set of rules and formats by which the control information (and user data) is exchanged between the two peers. The protocol caters for:
+
+- the set-up of logical signalling connection;
+- the release of logical signalling connections;
+- the transfer of data with or without logical signalling connections.
+
+## 5.4 Model of the connection-oriented network service
+
+A signalling connection is modelled in the abstract by a pair of queues. The protocol elements are objects on that queue added by the origination SCCP user and removed by the destination SCCP user. Each queue represents a flow control function. Figure 4 illustrates the modes described above.

+
+The diagram illustrates the connection-oriented network service model between Node A and Node B. Both nodes have a 'User of the network service' block. Below this, a large rectangular box represents the network. Inside this box, there are two horizontal queues, each represented by a dashed cylinder. The top queue is labeled 'Queue B to A' and has an arrow pointing from Node B to Node A. The bottom queue is labeled 'Queue A to B' and has an arrow pointing from Node A to Node B. The identifier 'T1157200-93' is located at the bottom right of the diagram.

+
+## 5.5 Model of the connectionless network service
+
+This service definition uses the abstract model for a layer service defined in clause 5/X.210. The model defines the interactions between the user and the provider of the connectionless network service. These interactions take place at the two SCCP-SAPs (see Figure 5).

+![Diagram of the connectionless network service model between Node X and Node Y.](08441fa90c5fd11994626f662ac13f19_img.jpg)
+
+The diagram illustrates the connectionless network service model between Node X and Node Y. Both nodes have a 'User of the network service' block. Below Node X is 'SCCP-SAP A' and below Node Y is 'SCCP-SAP B'. A large rectangular box labeled 'Service provider' contains a 'Virtual transient association between A and B', represented by a horizontal line with diagonal lines connecting to the SAPs. The identifier 'T1178310-96' is located at the bottom right of the diagram.
+

+
+**Figure 5/Q.711 – Model of a network connectionless transmission**
+
+A defining characteristic of network-connectionless transmission is the independent nature of each invocation of the connectionless network service. This basic service has been enhanced to provide sequence integrity between SDUs (see protocol class 1 service).
+
+The connectionless network service, as provided between SCCP-SAPs, can be modelled in the abstract as a virtual transient association between the SCCP-SAPs (see Note).
+
+NOTE – This model is intended solely to describe the appearance of the connectionless-mode network service to the SCCP users. It is not intended to be a model of the internal operation of the service provider in providing the connectionless network service.
+
+Only one type of object, the Unitdata, can be exchanged between the users of the service. This relationship is illustrated in Figure 5.
+
+## **5.6 Contents of the Q.71X-series Recommendations**
+
+ITU-T Q.711 contains a general description of the services provided by the MTP, the services provided by the SCCP and the functions within the SCCP.
+
+ITU-T Q.712 defines the function of the messages, the set of protocol elements and their embedding into messages.
+
+ITU-T Q.713 describes the formats and codes used for the SCCP messages.
+
+ITU-T Q.714 is a detailed description of the SCCP procedures as a protocol specification.
+
+ITU-T Q.715 is the SCCP user guide. Implementation-dependent aspects may be found in ITU-T Q.715.
+
+ITU-T Q.716 defines and specifies values for the SCCP performance parameters, including quality of service parameters and internal parameters.
+
+# **6 Services provided by the SCCP**
+
+The overall set of services is grouped into:
+
+- connection-oriented services;
+- connectionless services.
+
+Four classes of service are provided by the SCCP protocol, two for connectionless services and two for connection-oriented services.
+
+The four classes are:
+
+- 0 basic connectionless class;
+- 1 in-sequence delivery connectionless class;
+- 2 basic connection-oriented class;
+- 3 flow control connection-oriented class.
+
+In the tables defining individual primitives, the notations given below are used:
+
+- M indicates a mandatory parameter;
+- O indicates an SCCP implementation option;
+- C indicates that the parameter is conditional;
+- U indicates a user option;
+- n.a. not applicable;
+- = indicates that the parameter must have the same value in the indication primitive, or confirm primitive as provided in the corresponding request primitive, or response primitive, respectively.
+
+## **6.1 Connection-oriented services**
+
+A distinction has to be made between:
+
+- temporary signalling connections;
+- permanent signalling connections.
+
+Temporary signalling connections are under control (establishment, data transfer including reset, release) of the SCCP user. Further details are given in 6.1.1.
+
+Permanent signalling connections are established and released by Management (O&M function or management function) and are provided to the SCCP user on a semi-permanent basis, while data transfer including reset is under control of the SCCP user. Further details are given in 6.1.2.
+
+### **6.1.1 Temporary signalling connections**
+
+#### **6.1.1.1 Description**
+
+The control of a signalling connection is divided into the following phases:
+
+- connection establishment phase;
+- data transfer phase;
+- connection release phase.
+
+##### **6.1.1.1.1 Connection establishment phase**
+
+Connection establishment procedures provide the mechanism for establishing temporary signalling connections between users of the SCCP.
+
+A signalling connection between two SCCP users may consist of one or more connection sections. A signalling connection between two SCCP users in the same node is considered an implementation-dependent matter.
+
+During connection establishment, routing functions are provided by the SCCP, in addition to those provided by the MTP.
+
+At intermediate nodes, SCCP routing determines whether a signalling connection should be realized by one connection or by concatenated connection sections (i.e. coupling of connections). The criteria for deciding on coupling are implementation dependent.
+
+For connection establishment there are two alternative boundaries between SCCP and SCCP user with different procedures:
+
+- the "X.213-like" boundary that is described further in 6.1.1.2;
+- the "ISUP-embedded" boundary that is described further in 6.1.1.3.
+
+The "X.213-like" boundary requires that establishment procedures are performed by SCCP while in the case of "ISUP-embedded" boundary the ISUP provides the routing of the request for the set-up of a connection section.
+
+The connection refusal procedure is invoked if the SCCP or the SCCP user is unable to establish a signalling connection.
+
+##### **6.1.1.1.2 Data transfer phase**
+
+The data transfer service provides for an exchange of user data, called Network Service Data Units (NSDUs), in either direction or in both directions simultaneously on a signalling connection. An SCCP message between two peers consists of:
+
+- Network Protocol Control Information (NPCI);
+- Network Service Data Unit (NSDU).
+
+The network protocol control information supports the joint operating of the SCCP-peer entities within the two nodes communicating with each other. It contains a connection reference parameter which allocates the message to a certain signalling connection.
+
+The network service data unit contains a certain amount of information from the SCCP user which has to be transferred between two nodes using the service of the SCCP.
+
+The network protocol control information and the network service data unit are put together and transferred as a message (Figure 6). If the size of user data is too big to be transferred within one
+
+message, user data are segmented into a number of portions. Each portion is mapped to a separate message, consisting of the NPCI and an NSDU (Figure 7).
+
+![Diagram showing the relation between NSDU and message without segmentation or blocking. At the top, two boxes labeled 'NPCI' and 'NSDU' are shown.

+The data transfer service caters for sequence control and flow control depending on the quality of service required by the SCCP user (two different classes of the connection-oriented service are provided by the protocol; see ITU-T Q.714).
+
+##### 6.1.1.1.3 Connection release phase
+
+Connection release procedures provide the mechanism for disconnecting temporary signalling connections between users of the SCCP.
+
+#### 6.1.1.2 Network service primitives and parameters applicable to the X.213-like connection-oriented boundary
+
+##### 6.1.1.2.1 Overview
+
+Table 1 gives an overview of the primitives to the upper layers and the corresponding parameters for the (temporary) connection-oriented network service. Figure 8 shows an overview state transition diagram for the sequence of primitives at a connection endpoint.

+
+##### 6.1.1.2.2 Connection establishment phase
+
+An SCCP user (calling user) initiates the set-up of the connection by means of the primitive "N-CONNECT request" to the SCCP. The SCCP entity evaluates the primitive and adds the protocol control information. The SCCP message [consisting of the Protocol Control Information (PCI) and possibly an NSDU] is transmitted by means of the MTP-services to the remote peer entity of the SCCP. It evaluates and strips the PCI and sends a primitive "N-CONNECT indication" to the local SCCP user. On both ends of the connection, the status "pending" is assumed.
+
+The responding SCCP user answers with the primitive "N-CONNECT response" to the local SCCP, which sends the response SCCP message including PCI to the calling SCCP. The calling SCCP sends the primitive "N-CONNECT confirm" to the calling SCCP user. The connection is now ready for data transfer.
+
+The four types of N-CONNECT applicable to the X.213-like boundary, the request, the indication, the response and the confirm contain the parameters as shown and further described in Table 2.
+
+**Table 2/Q.711 – Parameters of the primitive N-CONNECT applicable to the X.213-like boundary**
+
+| Parameter                               | Primitive         |                      |                    |                     |

+| Importance                              | U                 | O                    | U                  | O                   |
+
+a<sup>1)</sup>) This parameter is associated with the SCCP service access point at which this primitive is issued if the calling address is absent.  
+a<sup>2)</sup>) This parameter is associated with the SCCP service access point at which this primitive is issued if the called address is absent.  
+a<sup>3)</sup>) This parameter is associated with the SCCP service access point at which this primitive is issued if the responding address is absent.  
+b<sup>)</sup>) In 5.3/X.213, this parameter is implicit.  
+c<sup>1)</sup>) If present in the received SCCP message.
+
+The parameters "called address/calling address" convey addresses identifying the destination/source of a communication. There are three types of address information elements:
+
+- global title;
+- subsystem number;
+- signalling point code (together with the MTP-SAP instance).
+
+The global title is an address such as dialled digits which does not explicitly contain information that would allow routing in the signalling network, i.e. a translation function is required. The subsystem number is an identification of a specific user function within a certain signalling point (SP), like the ISDN-user part, the SCCP-management, etc.
+
+The parameter "responding address" identifies the SCCP user to which the connection has been established or refused.
+
+The "responding address" parameter in the N-CONNECT primitive conveys the address of the SCCP service access point to which the signalling connection has been established. Under certain circumstances (e.g. a general global title identifying replicated subsystems), the value of this parameter may be different from the "called address" in the corresponding N-CONNECT request.
+
+The "responding address" parameter is present in the N-DISCONNECT primitive only in the case where the primitive is used to indicate rejection of a signalling connection establishment attempt by an SCCP user function. The parameter conveys the address of the service access point from which the N-DISCONNECT request was issued and under circumstances like that mentioned above the "responding address" may be different from the "called address" in the corresponding N-CONNECT request primitive.
+
+The parameter "expedited data selection" may be used to indicate during set-up whether expedited data can be transferred via the connection. A negotiation will be performed between SCCP users, local and remote.
+
+The quality of service parameter set is used during call set-up to negotiate the protocol class for the connection and, if applicable, the flow control window size.
+
+The N-CONNECT primitives may or may not contain user data.
+
+The parameter "connection identification" is used to allocate a primitive to a certain connection. The connection identification is an internal representation of the "connection endpoint identifier" defined in the OSI-RM. Its use and format is implementation dependent.
+
+The "importance" parameter is a user optional parameter in request and response primitives that result in the transmission of SCCP messages. Its use allows the SCCP user to assign and indicate to SCCP a certain importance to the primitive. During MTP and/or SCCP congestion, SCCP will take decisions to send out or reject the resulting message, based on this importance and on the severity of the congestion. Its presence in the indication and confirmation primitive is an SCCP implementation option.
+
+In principle, the connection establishment has to be completed (i.e. data transfer status has to be reached) before sending or receiving data messages. If data messages arrive at the calling user before the connection establishment is finished, these data messages are discarded.
+
+In addition, user data can also be transferred to and from the SCCP within the primitives N-CONNECT and N-DISCONNECT.
+
+##### 6.1.1.2.3 Data transfer phase
+
+During this phase three different primitives may occur:
+
+- a) N-DATA (Table 3);
+- b) N-EXPEDITED DATA (Table 4);
+- c) N-RESET (Table 5).

+
+The primitive "N-DATA" (Table 3) exists only as a "request", i.e. from the SCCP user to the local SCCP and as an "indication" at the remote end of the connection, i.e. from the SCCP to the local SCCP user. N-DATA can occur bidirectionally, i.e. from the calling as well as the called user of the SCCP-connection.
+
+The primitive "N-EXPEDITED DATA" may only be used by the SCCP user in case of protocol class 3 connections.
+
+The primitive N-RESET (Table 5) can occur in the data transfer state of a connection with a protocol class including flow control. N-RESET overrides all other activities and causes the SCCP to start a re-initialization procedure for sequence numbering. N-RESET appears as a request, an indication, a response and a confirm. After reception of an N-RESET request and before the sending of an N-RESET confirm, all NSDUs from the remote SCCP and the local SCCP user are discarded by the local SCCP.
+
+The parameter "originator" indicates the source of the reset and can be any of the following: the "network service provider" (network originated), the "network service user" (user originated), or "undefined". The parameter "reason" indicates "network service provider congestion", "reason unspecified" or "local SCCP originated<sup>1</sup>" for a network originated reset, and indicates "user synchronization" for a user originated reset. The "reason" parameter is "undefined" when the "originator" parameter is "undefined".
+
+##### 6.1.1.2.4 Release phase
+
+The primitives for the release phase are N-DISCONNECT request and N-DISCONNECT indication. These primitives are also used for the connection refusal during connection establishment phase. Parameters are included to notify the reason for connection release/refusal and the initiator of the connection release/refusal procedure. User data may be also be included (see Table 6).
+
+<sup>1</sup> These values may be used locally at the originating/initiating node as an implementation option.

+
+##### 6.1.1.3.2 Notice service
+
+The provision of the notice service by use of the "N-INFORM" primitive is implementation dependent.
+
+The primitive N-INFORM (Table 8) is used during data transfer to convey relevant network/user information. The primitive "N-INFORM" will contain the parameters "reason", "connection identification" and "QOS parameter set".
+
+**Table 8/Q.711 – Parameters of the primitive N-INFORM**
+
+| Parameter                 | Primitive        |                     |
+|---------------------------|------------------|---------------------|

+| Reason                    | M                | M                   |
+| Connection identification | O                | O                   |
+| QOS parameter set         | C <sup>c3)</sup> | C <sup>c3)</sup>    |
+
+<sup>c3)</sup> Present in inform reasons that lead to a QOS parameter set change.
+
+The primitive "N-INFORM request" is provided to inform the local SCCP of the connection user failure/congestion, or anticipated QOS changes. A further primitive "N-INFORM indication" is provided to indicate actual failures of the local SCCP to the SCCP-user functions or anticipated quality of service changes or other indications to the SCCP-user functions.
+
+The parameter "reason" contains the network/user information to be conveyed. It may assume the following values:
+
+- network service provider failure;
+- network service congestion;
+- network service provider QOS change;
+- network service user failure;
+- network service user congestion;
+- network service user QOS change;
+- reason unspecified.
+
+##### 6.1.1.3.3 Connection establishment making use of the ISUP-embedded procedures
+
+An SCCP user (calling user) may, instead of using the N-CONNECT request thereby requesting SCCP to transmit an appropriate PDU, use the REQUEST to solicit the SCCP to provide in the REPLY information relevant for connection establishment. The forward direction of the connection is established hop-by-hop making use of PDUs of ISUP thereby is embedded in the forward call set-up. In the backward direction, normal SCCP PDUs are used. The N-CONNECT request is replaced at the origin by the two interface elements REQUEST type 1 and REPLY. Within intermediate nodes the two interface elements REQUEST type 2 and REPLY are required.
+
+The three types of N-CONNECT applicable to the ISUP embedded boundary, the indication, the response and the confirm contain the parameters as shown in Table 9.
+
+**Table 9/Q.711 – Parameters of the primitive N-CONNECT applicable to the ISUP embedded boundary**

+
+<sup>a1)</sup> This parameter is associated with the SCCP service access point at which this primitive is issued if the responding address is absent.

+
+Three interface elements are defined for the information flow between SCCP and ISDN-user part:
+
+- a) REQUEST to the SCCP, type 1 and type 2;
+- b) REPLY from the SCCP.
+
+The REQUEST type 1 contains the following parameters:
+
+- connection identification (O);
+- expedited data selection (U);
+- quality of service parameter set (U).
+
+The REQUEST type 2 contains the following parameters:
+
+- quality of service parameter set (M);
+- connection identification (O);
+- source local reference (M);
+- originating signalling point code (M);
+- reply request (U);
+- refusal indicator (U).
+
+The REPLY contains the following parameters:
+

+- quality of service parameter set (M);
+- connection identification (O).
+
+### 6.1.2 Permanent signalling connections
+
+#### 6.1.2.1 Description
+
+The set-up/release service is controlled by the administration (e.g. OMAP). The functions for set-up and release may be similar to those provided for temporary signalling connections. The classes of service are the same.
+
+Permanently established signalling connections may require additional safeguarding mechanisms within the endpoints (relay points) of the connection in order to guarantee their re-establishment in case of a malfunction followed by a recovery.
+
+#### 6.1.2.2 Primitives and parameters
+
+The primitives and their parameters are listed in Table 10. Their content and functionality correspond to the description within 6.1.1.2.3.

+## 6.2 Connectionless services
+
+The SCCP provides the SCCP user with the ability to transfer signalling messages via the signalling network without set-up of a signalling connection. In addition to the MTP capability, a "routing" function has to be provided within the SCCP, which maps the called address to the signalling point codes of the MTP service.
+
+This mapping function is provided within each node, or is distributed over the network or is provided in some special translation centres.
+
+The SCCP also includes the ability to segment/reassemble user data that cannot be transferred in one MTP message. More details can be found in 4.1.1/Q.714.
+
+Under certain conditions of congestion and unavailability of subsystems and/or signalling points, connectionless messages in support of SCCP-SDUs could be discarded instead of being transferred. If the SCCP user wishes to be informed of the non-delivery of a SCCP-SDU caused by the discard of a message, the return option parameter must be set to "return SCCP-SDU on error" in the primitive to the SCCP.
+
+### 6.2.1 Description
+
+The connectionless SCCP offers two services:
+
+- Class 0: The basic connectionless class without guaranteed in-sequence delivery of SCCP-SDUs. The SCCP user can invoke this service by means of the parameter "sequence control" in the N-UNITDATA request primitive being absent; and
+
+Class 1: The in-sequence delivery connectionless class with guaranteed<sup>3</sup> in-sequence delivery of SCCP-SDUs. The SCCP user can invoke this service by means of the parameter "sequence control" in the N-UNITDATA request primitive being present.
+
+NOTE – These two services are provided by SCCP making use of the sequence control mechanisms provided by the MTP in a distinct way:
+
+- a) The class 0 service allows the SCCP to insert SLS values randomly, or with the aim to achieve an appropriate load sharing within the underlying MTP network.
+- b) The class 1 service requires the SCCP to insert the same SLS for all the SCCP-SDUs associated with given parameters "sequence control" and "called address".
+
+The rules to achieve load sharing in the MTP network are not defined in the SCCP Recommendations.
+
+### 6.2.2 Primitives and parameters of the connectionless service

+
+#### 6.2.2.2 Parameters
+
+##### 6.2.2.2.1 Address
+
+The parameters "called address" and "calling address" serve to identify the destination and origination respectively, of the SCCP-SDU to be conveyed in connectionless messages. It should be noted that the called and calling addresses may be different at the origination and destination. These parameters may contain some combination of global title, subsystem number and signalling point code.
+
+<sup>3</sup> By the MTP network or by concatenated MTP networks concerned (for further information, see ITU-T Q.706).
+
+The global title is an address such as dialled digits which does not explicitly contain information that would allow routing in the signalling network, i.e. a translation function is required. The subsystem number is an identification of a specific user function within a certain signalling node, like the ISDN-user part, the SCCP-management, etc.
+
+##### **6.2.2.2.2 Sequence control**
+
+The presence of the parameter "sequence control" indicates to the SCCP that the user requires to invoke the "sequence guaranteed" service. In the case of "sequence guaranteed" service, this parameter is an indication to the SCCP that a given stream of SCCP-SDUs has to be delivered in sequence. The value of this parameter together with the called address is also used to distinguish different streams of messages so that the SCCP can allocate SLS codes appropriately to help the MTP in achieving an even distribution of signalling traffic. If the SCCP user does not provide a sequence control parameter, then the SCCP assumes protocol class 0.
+
+##### **6.2.2.2.3 Return option**
+
+The parameter "return option" is used to determine the handling of SCCP-SDUs encountering transport problems.
+
+"Return option" may assume the following values:
+
+- discard SCCP-SDU on error;
+- return SCCP-SDU on error.
+
+If the SCCP user does not provide a return option parameter, then the SCCP assumes messages will be discarded on error, causing loss of SCCP-SDUs.
+
+##### **6.2.2.2.4 Reason for return**
+
+The parameter "reason for return" identifies the reason why a SCCP-SDU was not able to be delivered to its final destination.
+
+"Reason for return" may assume the following values:
+
+- no translation for an address of such nature;
+- no translation for this specific address;
+- subsystem congestion;
+- subsystem failure;
+- unequipped user;
+- MTP failure;
+- network congestion;
+- SCCP unqualified;
+- error in message transport;
+- error in local processing;
+- destination cannot perform reassembly;
+- SCCP failure;
+- hop counter violation;
+- segmentation not supported;
+- segmentation failed.
+
+##### **6.2.2.2.5 User data**
+
+The parameter "user data" is information which is to be transferred transparently between SCCP users. In the case of the N-NOTICE primitive, the "user data" parameter may be incomplete.
+
+##### 6.2.2.2.6 Importance
+
+The "importance" parameter is a user optional parameter in request primitives that result in the transmission of SCCP messages. Its use allows the SCCP user to assign and indicate to SCCP a certain importance to the primitive. During MTP and/or SCCP congestion, SCCP will take decisions to send out or reject the resulting message, based on this importance and on the severity of the congestion. Its presence in the indication primitives is an SCCP implementation option.
+
+#### 6.2.2.3 Primitives
+
+##### 6.2.2.3.1 UNITDATA
+
+The "N-UNITDATA request" primitive is the means by which an SCCP user requests the SCCP to transfer SCCP-SDUs to a peer SCCP user.
+
+The "N-UNITDATA indication" primitive informs a user that a SCCP-SDU is being delivered to it from the peer SCCP user.
+
+Table 12 indicates the parameters of the primitive N-UNITDATA.

+
+### 6.2.3 State transition diagram
+
+The network-connectionless transmission service primitive can be used to transmit a self-contained SCCP-SDU from one SCCP-SAP to another SCCP-SAP in a single service access; thus no initial establishment or subsequent release of a network-connection is required. This SCCP-SDU can be independent (class 0) or appear in a sequence where sequence integrity is preserved (class 1).
+
+The state transition diagram, as seen by the SCCP user using the services provided by the connectionless SCCP, is shown in Figure 9.

+## 6.3 SCCP management
+
+### 6.3.1 Description
+
+The SCCP provides SCCP management procedures (see clause 5/Q.714) to maintain network performances by rerouting or throttling traffic in the event of failure or congestion in the network. These SCCP management procedures apply to both the connection-oriented and the connectionless services of the SCCP.
+
+### 6.3.2 Primitives and parameters of the SCCP management
+
+#### 6.3.2.1 Overview
+
+Table 14 gives an overview of the primitives to the upper layers and the corresponding parameters for the SCCP management.

+
+#### 6.3.2.2 Parameters
+
+##### 6.3.2.2.1 Affected subsystem
+
+The parameter "affected subsystem" identifies a user which is failed, withdrawn, or allowed. The "affected subsystem" parameter contains the same type of information as the "called address" and "calling address", except the global title portion.
+
+##### 6.3.2.2.2 User status
+
+The parameter "user status" is used to inform a SCCP user of the status of the affected subsystem.
+
+"User status" may assume one of the following values:
+
+- User-in-service (UIS);
+- User-out-of-service (UOS).
+
+##### 6.3.2.2.3 Subsystem multiplicity indicator
+
+The parameter "Subsystem multiplicity indicator" identifies the number of replications of a subsystem. This parameter is reserved for national application.
+
+##### 6.3.2.2.4 Affected signalling point
+
+The parameter "affected signalling point" identifies a signalling point or SCCP which is failed, congested, or allowed. The "affected signalling point" parameter contains unique identification of a signalling point.
+
+##### 6.3.2.2.5 Signalling point status
+
+The parameter "signalling point status" is used to inform a user of the status of an affected signalling point.
+
+"Signalling point status" may assume the following values:
+
+- signalling point inaccessible;
+- signalling point congested;
+- signalling point accessible.
+
+##### 6.3.2.2.6 Remote SCCP status
+
+The parameter "remote SCCP status" is used to inform a user of the status of a remote SCCP.
+
+"Remote SCCP status" may assume the following values:
+
+- remote SCCP available;
+- remote SCCP unavailable, reason unknown;
+- remote SCCP unequipped;
+- remote SCCP inaccessible;
+- remote SCCP congested.
+
+##### 6.3.2.2.7 Restricted importance level
+
+The parameter "restricted importance level" is used to inform an SCCP user of the importance level at which traffic is being restricted by SCCP towards a remote signalling point or SCCP. When the user is able to identify the remote signalling point or SCCP, it may decide not to send any primitives of importance numerically below the level indicated that will result in messages towards the (SCCP at that) remote signalling point. Primitives of importance numerically equal to or greater than the level indicated will still be sent (to ensure equitable treatment with users not in a position to identify the remote signalling point or SCCP).
+
+#### 6.3.2.3 Primitives
+
+##### 6.3.2.3.1 COORD
+
+The "N-COORD" primitive (Table 15) is used by replicated subsystems to coordinate the withdrawal of one of the subsystems.
+
+**Table 15/Q.711 – Parameters of the primitive N-COORD**
+
+| Parameter                        | Primitive       |                    |                  |                 |
+|----------------------------------|-----------------|--------------------|------------------|-----------------|
+|                                  | N-COORD request | N-COORD indication | N-COORD response | N-COORD confirm |
+| Affected subsystem               | M               | M                  | M                | M               |
+| Subsystem multiplicity indicator | n.a.            | O                  | n.a.             | O               |
+
+The primitive exists as: a "request" when the originating user is requesting permission to go out-of-service; an "indication" when the request to go out-of-service is delivered to the originator's replicate; a "response" when the originator's replicate announced it has sufficient resources to let the originator go out-of-service; and as a "confirm" when the originator is informed that it may go out-of-service.
+
+##### 6.3.2.3.2 STATE
+
+The "N-STATE request" primitive (Table 16) is used to inform the SCCP management about the status of the originating user. The "N-STATE indication" primitive is used to inform an SCCP user accordingly.
+
+**Table 16/Q.711 – Parameters of the primitive N-STATE**

+| Subsystem multiplicity indicator | n.a.            | O                  |
+
+##### 6.3.2.3.3 PCSTATE
+
+The "N-PCSTATE primitive" (Table 17) is used to inform a user about the status of a signalling point or a remote SCCP.

+- a) An MTP-SAP that supports a maximum MTP-SDU size of 272 octets, including the MTP routing label (see 2.3.8/Q.703).
+- b) An MTP-SAP that supports a maximum MTP-SDU size of 4095 octets, including the MTP routing label (see 9.1/Q.2210).
+
+With the exception of the maximum supported SDU size, these two SAPs offer equivalent services.
+
+## 7.2 MTP primitives and parameters
+
+The primitives supported by the MTP are specified in Table 1/Q.701 (MTP-3), and Table 1/Q.2210 (MTP-3b), respectively. Table 18 specifies how the MTP primitives apply when SCCP is using the services of the MTP. In the case of conflicting statements between this Recommendation and ITU-T Q.701 or ITU-T Q.2210, ITU-T Q.701 and ITU-T Q.2210 take precedence.

+
+<sup>a)</sup> The SCCP should assist load sharing within the underlying MTP network by making use of an appropriate choice of SLS values (distributed as equally as possible). Where in-sequence delivery is required, the same SLS value should be used.
+
+<sup>b)</sup> The cause parameter has, at present, four values:
+
+- i) Signalling network congested (plus optional level).  
+The level value is included if national options with congestion priorities or multiple signalling link states without congestion priorities as in ITU-T Q.704 are implemented.
+- ii) User part unavailability: unknown (user part identity is SCCP).
+- iii) User part unavailability: unequipped remote user (user part identity is SCCP).
+- iv) User part unavailability: inaccessible remote user (user part identity is SCCP).  
+If the cause was "unknown", "inaccessible remote user" or "signalling network congestion" without "level", it is the responsibility of the SCCP to determine when the remote SCCP is again available.
+
+<sup>c)</sup> If the selected MTP-SAP instance is an MTP as described in ITU-T Q.701 to ITU-T Q.707, the "user data" parameter is defined in 2.3.8/Q.703. If the selected MTP-SAP instance is an MTP as described in ITU-T Q.2210 ("MTP-3b"), the parameter "user data" is as defined in 9.1/Q.2210.
+
+### 7.2.1 TRANSFER
+
+The primitive "MTP-TRANSFER" is used between SCCP and MTP to provide the MTP message transfer service.
+
+### 7.2.2 PAUSE
+
+The primitive "MTP-PAUSE" indicates to the SCCP the total inability of providing the MTP service to the specified destination<sup>4</sup>.
+
+NOTE – The signalling point is inaccessible via the MTP. The MTP will determine when the signalling point is again accessible and send MTP-RESUME indication. The user should wait for such an indication and, meanwhile, is not allowed to send messages to that signalling point. If the remote peer user is thought to be unavailable, that condition may be maintained or cancelled at the local user's discretion.
+
+<sup>4</sup> If MTP provides services according to ITU-T Q.704, see 7.2.6/Q.701, items iii), iv) and v); otherwise, this reference to ITU-T Q.701 does not apply.
+
+### **7.2.3 RESUME**
+
+The primitive "MTP-RESUME" indicates to the SCCP the ability of providing the MTP service to the specified destination<sup>4</sup>.
+
+This primitive corresponds to the destination accessible state as defined in ITU-T Q.704.
+
+NOTE – When the "MTP-RESUME" indication is given to each user, the MTP does not know whether the remote peer user is available. This is the responsibility of each user.
+
+### **7.2.4 STATUS**
+
+The primitive "MTP-STATUS" indicates to the SCCP the partial inability of providing the MTP service to the specified destination. The primitive is also used to indicate to a user that a remote corresponding user is unavailable and the cause for unavailability (see 11.2.7/Q.704).
+
+In the case of national option with congestion priorities and multiple signalling link congestion states without priorities, as in ITU-T Q.704, are implemented, this "MTP-STATUS" primitive is also used to indicate a change of congestion level.
+
+This primitive corresponds to the destination congested/user part unavailable state as defined in ITU-T Q.704.
+
+NOTE – In the case of remote user unavailability, the user is responsible for determining the availability of this peer user. The user is cautioned not to send normal traffic to the peer user because, while such peer user is unavailable, no message will be delivered but each will result in a repeated MTP-STATUS indication. The MTP will not send any further indications about the unavailability or availability of this peer user unless the local user continues to send messages to the peer user.
+
+### **7.2.5 Notification of completion of MTP restart procedure**
+
+When the MTP restart procedure is terminated, the MTP indicates the end of MTP restart to all local MTP users showing each signalling point's accessibility or inaccessibility. The means of doing this is implementation dependent (see clause 9/Q.704), but it is modelled by the MTP-RESUME indications or MTP-PAUSE indications at the appropriate MTP-SAP instance in the state transition diagrams of 7.3.
+
+## **7.3 State transition diagram**
+
+The state transition diagrams, as seen by the SCCP using the services provided by the MTP, are shown in Figures 10, 11 and 12.
+
+Each state transition diagram applies to a single signalling relation; therefore, there exist as many state transition diagrams as there are signalling relations. Figure 10 is an abstract model of the interface between the MTP and the SCCP. It is not reflected in the management procedures and the SDL diagrams in ITU-T Q.714.

+
+# **8 Functions provided by the SCCP**
+
+This clause is an overview of the functional blocks within the SCCP.
+
+## **8.1 Connection-oriented functions**
+
+### **8.1.1 Functions for temporary signalling connections**
+
+#### **8.1.1.1 Connection establishment functions**
+
+The connection establishment service primitives defined in 6.1 are used to set up a signalling connection.
+
+The main functions of the connection establishment phase are listed below:
+
+- set up of a signalling connection;
+- establish the optimum size of NPDUs (network protocol data unit);
+- map network address onto signalling relations;
+- select functions operational during data transfer phase (for instance, layer service selection);
+- provide means to distinguish network connections;
+- transport user data (within the request).
+
+#### **8.1.1.2 Data transfer phase function**
+
+The data transfer phase functions provide means for a two-way simultaneous transport of messages between the two endpoints of the signalling connection.
+
+The main functions of the data transfer phase as listed below are used or not used in accordance with the result of the selection performed in the connection establishment phase:
+
+- segmenting/reassembling;
+- flow control;
+- connection identification;
+- NSDU delimiting (Mbit);
+- expedited data;
+- missequence detection;
+- reset;
+- others.
+
+#### **8.1.1.3 Release phase functions**
+
+These functions provide disconnection of the signalling connection, regardless of the current phase of the connection. The release may be performed by an upper layer stimulus or by maintenance of the SCCP itself. The release can start at each end of the connection (symmetrical procedure).
+
+The main function of the release phase is the disconnection.
+
+### **8.1.2 Functions for permanent signalling connections**
+
+#### **8.1.2.1 Connection establishment phase and connection release phase functions**
+
+The stimuli for set-up and release of permanent connections are originated from the administration function.
+
+#### **8.1.2.2 Data transfer phase functions**
+
+The functions for the data transfer on permanent signalling connections correspond to that for temporary connections. Differences may exist regarding the quality of service.
+
+## **8.2 Connectionless service functions**
+
+The functions of the connectionless service are listed below:
+
+- mapping the network address to signalling relations;
+- sequence service;
+- segmenting.
+
+## **8.3 Management functions**
+
+The SCCP provides functions which manage the status of the SCCP subsystems. These functions allow other nodes in the network to be informed of the change in status of SCCP subsystems at a node, and to modify SCCP translation data if appropriate.
+
+SCCP management also keeps track of the congestion status of MTP destinations and remote SCCPs.
+
+For subsystems running in dominant mode or loadshared mode, a possibility is foreseen to negotiate taking one replicated subsystem out of service with the other subsystem remaining in service. This allows to check whether the other side is capable (i.e. has enough resources, real time) to receive the extra traffic load. The replicated subsystem initiating the procedure is taken out of service only after the other subsystem has answered positively to the request.
+
+When a subsystem is out of service, SCCP test functions are activated at nodes receiving unavailability information. At periodic intervals the status of the unavailable subsystem is checked by an SCCP management procedure.
+
+Broadcast functions within SCCP management broadcast subsystem status changes to nodes within the network which have an immediate need to be informed of a particular signalling point/subsystem status change.
+
+Notification functions to local subsystems within the node (local broadcast) are also provided.
+
+The capability of a remote SCCP node to test the availability of a subsystem at a restarting SCCP node before resuming traffic to that node or subsystem is for further study. The capability of a remote SCCP node to test the availability of the SCCP when the signalling point becomes accessible, before resuming traffic to/via that node, is for further study. In addition, the application of these tests and the protocol specification are for further study. See 5.2.3/Q.714 and 5.3.4.2/Q.714.
+
+## **8.4 Routing and translation functions**
+
+The SCCP routing provides a powerful address translation function, which is asked for connectionless and connection-oriented service. The SCCP routing provides a powerful addressing information translation function on behalf of its users. This function makes it unnecessary for SCCP users to store knowledge of SCCP signalling routing information. The routing function also responds to the MTP and SCCP congestion reports. Detailed description of the SCCP routing function can be found in 2.3/Q.714 and 2.4/Q.714.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.

+## 6.1 Description
+
+### 6.1.1 General description
+
+The CLIP supplementary service is a supplementary service offered to the called user. It presents the calling user's number, with additional address information (e.g., the calling party sub-address) if any, to the called user. When provided, the facility applies to all incoming calls except for when the calling user has activated the calling line identification restriction (CLIR) supplementary service (see [ITU-T Q.731.4]) or the complete number of the calling user is not available at the destination exchange.
+
+The calling party number may be provided by the originating local exchange or by the access signalling system of the calling user. The calling party number may also be provided by transit exchange which is connected to the customer premises equipment (CPE) using Signalling System No. 7.
+
+The calling party sub-address (if provided by the access signalling system) shall be transported transparently by the network in the access transport parameter. The network cannot be responsible for the content of this sub-address.
+
+Information indicating that a subscriber has the CLIP supplementary service facility is available in the exchange to which the subscriber is connected to.
+
+The stage 1 service description is given in [ITU-T I.251.3], and the stage 2 functional capabilities and information flows are given in [ITU-T Q.81.3]. The stage 3 DSS1 description is given in [ITU-T Q.951.3]. This stage 3 description of the CLIP supplementary service uses the integrated services digital network (ISDN) user part protocol as defined in [ITU-T Q.761], [ITU-T Q 764] and [ITU-T Q.730].
+
+### 6.1.2 Specific terminology
+
+In addition to the term defined in clause 3, this Recommendation uses the following specific terminology:
+
+**ISDN number** – A number conforming to the numbering plan and structure specified in [ITU-T E.164].
+
+**National (ISDN) number; National significant (ISDN) number** – See [ITU-T E.164].
+
+**International (ISDN) number** – See [ITU-T E.164].
+
+**Sub-address** – See [ITU-T E.164].
+
+**Served user** – The user of a particular ISDN number who has subscribed to the presentation of the calling line identification information in association with incoming calls. The served user is also known as the called user.
+
+**Calling user** – The user that initiated an incoming call at the served user. The calling user needs not to have subscribed to the CLIP supplementary service.
+
+**Default number** – A national significant ISDN number registered within the public ISDN following prior arrangement between the calling user and the public ISDN.
+
+**Special connection arrangement** – An arrangement between a customer and a public network operator whereby customer supplied calling party numbers are not screened by the public network.
+
+**Access signalling system** – A part in the local exchange that handles the user-network interface protocol. It also includes the screening functions.
+
+**CPE connected signalling system No. 7** – A part in the transit exchange that handles the SS No. 7 protocol used between transit exchange and CPE. It also includes the screening functions.

+
+## 6.3 Coding requirements
+
+- i) Coding requirements if a special connection arrangement does not apply
+- Clause 3.10 of [ITU-T Q.763] and clause 3.2 of [ITU-T Q.763] give the coding for the calling party number and the access transport parameter which are required to support this service.
+- The purpose of the calling party number parameter is to identify the origin of a call.
+
+- The access transport parameter transports the calling party sub-address information element as defined in clause 4.5.11 of [ITU-T Q.931], which is to identify a sub-address associated with the origin of the call.
+- ii) Coding requirements if a special connection arrangement applies
+  - In addition to the coding requirements of i) above, the generic number parameter as specified in clause 3.26c) of [ITU-T Q.763] is required.
+  - The purpose of the generic number parameter is to transport a calling party number provided by the calling user with a special connection arrangement.
+  - The generic number parameter is accompanied by the parameter compatibility information parameter as specified in clause 3.41 b) of [ITU-T Q.763]. The procedures for the compatibility are defined in clause 2.9.5 of [ITU-T Q.764].
+  - The allowed coding for the generic number parameter is as follows:
+    - a) Number qualifier indicator  
+00000110 additional calling party number
+    - b) Odd/even indicator  
+See clause 3.9 a) of [ITU-T Q.763]
+    - c) Nature of address indicator  
+0000001 subscriber number (for national use)  
+0000010 unknown (for national use)  
+0000011 national (significant) number  
+0000100 international number
+    - d) Internal network number indicator/number incomplete indicator (not used)  
+0
+    - e) Numbering plan indicator  
+001 ISDN (Telephony) numbering plan [ITU-T E.164]
+    - f) Address presentation restricted (Pres. Restric.) indicator  
+00 presentation allowed  
+01 presentation restricted
+    - g) Screening indicator  
+00 user provided, not verified  
+10 user provided, verified and failed (for national use)
+    - h) Address signals  
+0000 digit 0  
+0001 digit 1  
+0010 digit 2  
+0011 digit 3  
+0100 digit 4  
+0101 digit 5  
+0110 digit 6  
+0111 digit 7  
+1000 digit 8

+
+## **6.4 Signalling requirements**
+
+### **6.4.1 Activation/deactivation/registration**
+
+Not applicable.
+
+### **6.4.2 Invocation and operation**
+
+#### **6.4.2.1 Actions at the originating local exchange**
+
+###### **6.4.2.1.1 Normal operation**
+
+All information pertaining to the CLIP supplementary service shall be inserted in the initial address message sent as part of the basic call procedures according to [ITU-T Q.764].
+
+The calling party sub-address (if provided by the access signalling system) shall be transported transparently by the network in the access transport parameter.
+
+If the numbering plan indicator received from the access signalling system together with a calling party number is coded other than "ISDN (Telephony) numbering plan [ITU-T E.164]" or "unknown", then the calling party number received from the access signalling system shall be discarded and the processing of the call shall continue as if no calling party number was received. If the numbering plan indicator received from the access signalling system is coded "unknown", then the originating local exchange shall treat this value as if the value "ISDN (Telephony) numbering plan [ITU-T E.164]" was received.
+
+If the screening indicator received from the access signalling system together with the calling party number is coded "user provided, not verified", then the calling party number shall be entered in the generic number parameter. In this parameter, the number qualifier indicator shall be set to "additional calling party number" and the screening indicator to "user provided, not verified". If the numbering plan indicator received is coded "ISDN (Telephony) numbering plan [ITU-T E.164]" or "unknown", then the nature of address indicator shall be set to "international number" or "national (significant) number" as received from the access signalling system.
+
+NOTE 1 – As a national option, some networks may allow for the screening indicator "user provided, verified and failed". If this screening indicator is supported, then the originating local exchange shall treat this value in the same manner as the value "user provided, not verified".
+
+In addition, the originating local exchange shall enter the default number associated with that access in the calling party number parameter. In this parameter, the screening indicator shall be set to "network provided" and the nature of address indicator to "national (significant) number".
+
+If the screening indicator received from the access signalling system together with the calling party number is coded other than "user provided, not verified", then the originating local exchange shall enter the calling party number as received from the access signalling system in the calling party number parameter. The screening indicator of the calling party number parameter shall be set as received from the access signalling system.
+
+NOTE 2 – In the latter case, allowed values for the screening indicator are "network provided" and "user provided, verified and passed".
+
+If no calling party number is received from the access signalling system, the originating local exchange shall enter the default number associated with that access in the calling party number parameter. The screening indicator shall be set to "network provided" and the nature of address indicator to "national (significant) number".
+
+The calling party number incomplete indicator of the calling party number parameter shall be set to "complete".
+
+The numbering plan indicator of the calling party number parameter shall be set to "ISDN (Telephony) numbering plan [ITU-T E.164]".
+
+The numbering plan indicator of the generic number parameter shall be set to "ISDN (Telephony) numbering plan [ITU-T E.164]" if this value or "unknown" was received from the access signalling system.
+
+The address presentation restricted indicators of the calling party number and the generic number parameter shall both be set to the value "presentation allowed" or "presentation restricted" as received from the access signalling system.
+
+The actions at the originating local exchange and the resulting codepoints are summarized in Table 6-1.

+
+#### 6.4.2.2 Actions at the transit exchange
+
+###### 6.4.2.2.1 Normal operation
+
+A transit exchange shall transfer all information relating to the CLIP and CLIR supplementary services transparently to the succeeding exchange.
+
+NOTE – In interworking with the mobile network, the mobile telephony exchange may provide the transit exchange with an international calling party number that has a country code other than the country code of the transit exchange.
+
+###### 6.4.2.2.2 Exceptional procedures
+
+When transit exchange connects to a customer premises equipment through SS No. 7, following actions (e.g., ignore the information, use a default value) shall be taken.
+
+If no CLI parameter is received from the CPE connected signalling system No. 7 (CPE-SS7) or number incomplete indicator of the CLI parameter is "incomplete", the transit exchange shall enter the default number associated with the CPE-SS7 in the calling party number parameter. The screening indicator shall be set to "network provided" and the nature of address indicator shall be set to "national (significant) number".
+
+If the numbering plan indicator received from the CPE-SS7 together with a calling party number is coded other than "ISDN (Telephony) numbering plan [ITU-T E.164]" or "unknown", then the calling party number received from the CPE-SS7 shall be discarded and the processing of the call shall continue as if no CLI parameter was received. If the numbering plan indicator received from the CPE-SS7 is coded "unknown", then the transit exchange shall treat this value as if the value "ISDN (Telephony) numbering plan [ITU-T E.164]" was received.
+
+If the screening indicator received from the CPE-SS7 together with the calling party number is coded "user provided, not verified" or "user provided, verified and failed", then the transit exchange shall enter the default number associated with the CPE-SS7 in the calling party number parameter. The screening indicator of the calling party number parameter shall be set to "network provided" and the nature of address indicator shall be set to "national (significant) number". The calling party number can be entered in the generic number parameter according to pre-defined policy. In generic number parameter, number qualifier indicator shall be set to "additional calling party number" and screening indicator shall be set as received. In other cases, generic number parameter "number qualifier indicator" set to "additional calling party number" shall not be sent even if it is received from CPE-SS7.
+
+If the screening indicator received from the CPE-SS7 is "network provided" or "user provided, verified and passed", then:
+
+- if the received calling party number is associated with the CPE-SS7, then the transit exchange shall enter the calling party number as received from CPE-SS7 in the calling party number parameter. The screening indicator of the calling party number parameter shall be set as received from the CPE-SS7.
+- if the received calling party number is not associated with the CPE-SS7, then the transit exchange shall enter the calling party number as the default number associated with the CPE-SS7 in the calling party number parameter. The screening indicator of the calling party number parameter shall be set to "network provided" and the nature of address indicator shall be set to "national (significant) number".
+
+The calling party number incomplete indicator of the calling party number parameter shall be set to "complete".
+
+The address presentation restricted indicators of the calling party number shall be set to the value associated with the CPE-SS7.
+
+The actions at the transit exchange that connect to CPE-SS7 and the resulting codepoints are summarized in Table 6-2.

+
+#### 6.4.2.3 Actions at the outgoing international gateway exchange
+
+###### 6.4.2.3.1 Normal operation
+
+If the address presentation restricted indicator of the received calling party number parameter is set to "presentation restricted", the outgoing international gateway exchange shall act according to the bilateral agreement between the two networks (see clauses 2.1 and 5 of [ITU-T I.251.4]). If the address presentation restricted indicator of the received calling party number parameter is set to "address not available", then the calling party number parameter shall be omitted from the initial address message. If the calling party number parameter is not sent across the international section, then the generic number parameter shall be omitted from the initial address message if its number qualifier indicates "additional calling party number".
+
+The exchange shall convert the calling party number conveyed in the calling party number parameter to an international number (if necessary) and set the nature of address indicator to "international number". The address presentation restricted indicator and the screening indicator shall be transferred transparently.
+
+If the generic number parameter is received and its number qualifier indicates "additional calling party number" and the numbering plan indicator is coded "ISDN (Telephony) numbering plan [ITU-T E.164]", then the generic number parameter shall be treated in the same manner as the calling party number parameter.
+
+NOTE 1 – Without bilateral agreement for the transport of "user provided, verified and failed" numbers between networks, the generic number parameter shall be discarded if its number qualifier indicates "additional calling party number" and the screening indicator is coded "user provided, verified and failed".
+
+NOTE 2 – The address presentation restricted indicator in both the calling party number and generic number parameters are set to the same value. They can have the values "presentation allowed" or "presentation restricted" (based on the bilateral agreement).
+
+###### 6.4.2.3.2 Exceptional procedures
+
+If no calling party number parameter is received from the incoming network, then no calling party number parameter shall be sent to the succeeding exchange.
+
+If the calling party number incomplete indicator is set to "incomplete", then no calling party number parameter shall be sent to the succeeding exchange.
+
+#### **6.4.2.4 Actions at the incoming international gateway exchange**
+
+###### **6.4.2.4.1 Normal operation**
+
+The exchange shall check if the country code of the calling party number is the network's own country code. If this is the case, then the country code shall be removed. The nature of address indicator shall be set to "national (significant) number". The address presentation restricted indicator and the screening indicator shall be transferred transparently.
+
+NOTE – As a national option, the incoming international gateway exchange may add a prefix to the calling party number. In this case the nature of address indicator shall be set to "unknown".
+
+If the generic number parameter is received and its number qualifier indicates "additional calling party number" and the numbering plan indicator is coded "ISDN (Telephony) numbering plan [ITU-T E.164]", then the generic number parameter shall be treated in the same manner as the calling party number parameter.
+
+###### **6.4.2.4.2 Exceptional procedures**
+
+If no calling party number parameter is received from the preceding exchange, then no calling party number parameter shall be sent to the outgoing network.
+
+If the address presentation restricted indicator of the received calling party number parameter is set to "address not available", then this value shall be passed on transparently. The screening indicator shall be set to "network provided".
+
+NOTE – As a national option, the nature of address indicator in the calling party number parameter can be set to "unknown".
+
+#### **6.4.2.5 Actions at the destination local exchange**
+
+###### **6.4.2.5.1 Normal operation**
+
+When the destination local exchange receives an initial address message, basic call handling shall occur and the exchange shall send a set-up request to the access signalling system.
+
+It is a function of the user-network interface to check whether the called user has subscribed to the CLIP supplementary service or not and not to present the calling party sub-address, where appropriate, to the user.
+
+If the generic number parameter with a number qualifier set to "additional calling party number" is provided, then the information conveyed in this parameter shall be presented first to the access signalling system. The information conveyed in the calling party number parameter shall be sent to the access signalling system immediately following the information of the generic number parameter.
+
+Where the generic number parameter is not provided but the calling party number parameter is present, then the information conveyed in the calling party number parameter shall be sent to the access signalling system.
+
+All the available information shall be sent to the access signalling system.
+
+###### **6.4.2.5.2 Exceptional procedures**
+
+No exceptional procedures are identified.

+## **6.6 Interactions with other networks**
+
+On calls to or via non-ISDNs or an ISUP as defined in [ITU-T Q.767], where the succeeding signalling section supports only one calling party number to be carried, the information contained in the calling party number parameter shall be forwarded. The generic number parameter shall be discarded.
+
+Interworking exchanges may generate only part of the calling line identity for inclusion in the initial address message (e.g., trunk code). This shall be indicated in the number incomplete indicator in the calling party number parameter.
+
+On calls incoming from some non-ISDNs, the calling party number may be delivered to the destination ISDN without an indication of calling line identity restriction or the calling party number may be incomplete. In the case where there is no indication of presentation allowed or restricted, the interworking exchange shall act according to its rules and regulations. In the case where the number incomplete indicator received together with the calling party number indicates "incomplete", the information conveyed in the calling party number parameter is passed to the access signalling system.
+
+## **6.7 Signalling flows**
+
+No CLIP supplementary service specific signalling flow is necessary in addition to the basic call control according to [ITU-T Q.764].
+
+## **6.8 Parameter values (timers)**
+
+No specific timers are required.
+
+## **6.9 Dynamic description**
+

+![Flowchart of the ISUP protocol dynamic description for an originating local exchange. The process starts at 'Idle', goes to 'Setup IAM', then checks if CLI is provided. If 'No', it sets default CPN parameters. If 'Yes', it checks the NPI. If 'Other', it discards CLI. If 'ITU-T E.164' or 'unknown', it checks if SI is 'user provided, not verified'. If 'No', it sets default CPN parameters. If 'Yes', it sets GN or CPN parameters based on NOTE 1, then sets presentation restrictions and sends 'IAM' to end at 'Idle'.](5b8a756d9a71c35f17db8bcb90b438a3_img.jpg)

+Flowchart of the ISUP protocol dynamic description for an originating local exchange. The process starts at 'Idle', goes to 'Setup IAM', then checks if CLI is provided. If 'No', it sets default CPN parameters. If 'Yes', it checks the NPI. If 'Other', it discards CLI. If 'ITU-T E.164' or 'unknown', it checks if SI is 'user provided, not verified'. If 'No', it sets default CPN parameters. If 'Yes', it sets GN or CPN parameters based on NOTE 1, then sets presentation restrictions and sends 'IAM' to end at 'Idle'.
+
+NOTE 1 – As a national option, some networks may allow for the screening indicator "user provided and failed". If this screening indicator is supported, then the originating local exchange shall treat this value in the same manner as the value "user provided, not verified".
+
+NOTE 2 – This procedure operates independently from any CLIP subscription by the calling user and is provided as part of the basic service.
+
+NOTE 3 – This transition specifies additional processing to that described in Annex H of [ITU-TQ.764].

+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE

+
+## 6.1 Description
+
+### 6.1.1 General description
+
+Connected line identification presentation (COLP) is a user facility that enables a user to be informed, on outgoing calls, of the address of the connected party. When provided, the facility applies to all outgoing calls except for when the connected party has the connected line identity restriction (COLR) facility active.
+
+The connected number may be provided by the destination local exchange or by the access signalling system of the connected user. If the connected number is received from the connected user, the information is normally verified and passed to the originating exchange. If no information is received from the connected user, the destination exchange shall generate the connected number.
+
+By special arrangement, verification of the connected number information provided by the user may be inhibited. The information is conveyed by the network in the generic number parameter field of the answer (ANM) or connect (CON) message. The service has no impact on the signalling procedures.
+
+The connected line identity (COL) is the ISDN number of the connected party (with additional address information,
+
+e.g., connected party sub-address, if any) which may be provided by the network or by the connected party or partially by the network with the rest provided by the connected party.
+
+Only full international number, i.e., including the country code, should be passed across the international boundary.
+
+Moreover, the information on the COL may include address information generated by the connected user and transparently transported by the network. The sub-address is subject to a maximum of 20 octets. The network is not responsible for the content of this additional address information.
+
+The stage 1 CCITT definition for the COLP service is given in [ITU-T I.251.5]. The stage 2 CCITT description is contained in [ITU-T Q.81.5]. The stage 3 DSS 1 description is given in [ITU-T Q.951.5]. This stage 3 description of COLP and COLR uses the ISDN user part protocol as defined in [ITU-T Q.761] to [ITU-T Q.764] and [ITU-T Q.730].
+
+### 6.1.2 Specific terminology
+
+In addition to the term defined in clause 3, this Recommendation uses the following specific terminology:
+
+**ISDN number** – A number conforming to the numbering plan and structure specified in [ITU-T E.164].
+
+**Sub-address** – See Clause 5.4 of [ITU-T I.330].
+
+**Served access** – It is the user of a particular ISDN number who has subscribed to the presentation of the connected line identification information in association with outgoing calls. The served user may also be known as the calling access.
+
+**Connected access** – It is the user that receives an incoming call from the served user. The connected access need not have subscribed to the COLP supplementary service.
+
+**Default number** – A national significant ISDN number registered within the public ISDN following prior arrangement between the connected access and the public ISDN.
+
+**Special arrangement** – An arrangement between a customer and a public network operator whereby customer supplied connected numbers are not screened by the public network.
+
+**Access signalling system** – A part in the local exchange which handles the user-network interface protocol. It also includes the screening functions.
+
+### **6.1.3 Qualification on the applicability to telecommunication services**
+
+Not applicable.
+
+### **6.1.4 State definitions**
+
+No specific state definitions are required.
+
+## **6.2 Operational requirements**
+
+### **6.2.1 Provision/withdrawal**
+
+See clause 3.1 of [ITU-T I.251.5].
+
+### **6.2.2 Requirements on the originating network side**
+
+Not applicable.
+
+### **6.2.3 Requirements in the network**
+
+No specific requirements are needed in the network.
+
+### **6.2.4 Requirements on the terminating network side**
+
+Not applicable.
+
+## **6.3 Coding requirements**
+
+Clause 3.16 of [ITU-T Q.763], clause 3.38 of [ITU-T Q.763] and clause 3.26 of [ITU-T Q.763] give the coding for the connected number, optional forward call indicators, generic number parameters and the access transport parameter fields which are required to support this service.
+
+The purpose of the generic number parameter field is to transport a connected number provided by the connected user with a special arrangement. This screening indicator shall be set to "user provided, not verified".
+
+The generic number parameter is accompanied by the parameter compatibility information parameter. The procedures for compatibility are defined in [ITU-T Q.764].
+
+### **Allowed codings for the generic number parameter**
+
+- a) *Number qualifier indicator*  
+00000101 additional connected number
+
+- b) *Odd/even indicator*  
+See clause 3.26 b) of [ITU-T Q.763]
+- c) *Nature of address indicator*  
+0000001 subscriber number (for national use)

+## **6.4 Signalling requirements**
+
+### **6.4.1 Activation/deactivation/registration**
+
+Not applicable.
+
+### **6.4.2 Invocation and operation**
+
+#### **6.4.2.1 Actions at the originating local exchange**
+
+##### **6.4.2.1.1 Normal operation**
+
+When the calling party has subscribed to the COLP facility, the exchange shall include in the optional forward call indicator in the IAM, a request to use the COLP facility for this call.
+
+The COL information is conveyed by the network in the connected number parameter field of the answer (ANM) or connect (CON) message, unless the user has an agreement to provide unscreened information, in which case the connected number parameter field will convey the network default
+
+number, and the user provided unscreened information will be carried as received from the access signalling system in the generic number parameter also conveyed in the ANM or CON message.
+
+When the generic number parameter field with a number qualifier set to "additional connected number" is provided together with the connected number, then this number shall be sent in addition, to the calling access. The address presentation restricted indicator and screening indicator sent to the calling access shall be passed transparently.
+
+When the calling party has not subscribed to the COLP facility no particular actions are required. When a request for the COL is not included in the IAM, the connected number parameter should not be included in either the answer or connect message. However, if this information is included, it shall not be considered as a protocol error and the call should continue.
+
+It is a function of the user-network interface to check whether the calling user has subscribed to the COLP supplementary service, and not to present the COL or sub-address if no subscription exists.

+##### **6.4.2.1.2 Exceptional procedures**
+
+No exceptional procedures are identified.
+
+#### **6.4.2.2 Actions at the transit exchange**
+
+##### **6.4.2.2.1 Normal operation**
+
+The transit exchange shall transparently pass on all information related to the COLP supplementary service.
+
+##### **6.4.2.2.2 Exceptional procedures**
+
+No exceptional procedures are identified.
+
+#### **6.4.2.3 Actions at the outgoing international gateway exchange**
+
+##### **6.4.2.3.1 Normal operation**
+
+The exchange shall check if the country code of the connected number is the network's own country code. If this is the case then the country code shall be removed. The nature of address indicator shall be set to "national (significant) number". The address presentation restricted indicator and the screening indicator shall be transferred transparently.
+
+NOTE – As a national option, the outgoing international gateway exchange may add a prefix to the connected number. In this case the nature of address indicator shall be set to "unknown".
+
+If the generic number parameter field is received and its number qualifier indicates "additional connected number", and the numbering plan indicator is coded "ISDN (Telephony) numbering plan ([ITU-T E.164])", then the generic number parameter shall be treated in the same manner as the connected number parameter.
+
+##### **6.4.2.3.2 Exceptional procedures**
+
+No exceptional procedures are identified.
+
+#### **6.4.2.4 Actions at the incoming international gateway exchange**
+
+##### **6.4.2.4.1 Normal operation**
+
+At the international boundary, the destination gateway can remove the COL digits if it cannot be released to the originating network and set the address presentation restricted indicator to "address not available".
+
+If the address presentation restricted indicator of the received connected number parameter field is set to "presentation restricted", the destination international gateway exchange shall act according to the bilateral agreement between the two networks. If the connected number parameter field is not
+
+sent across the international section, then the generic number parameter field shall also be omitted from the CON or ANM message if its number qualifier indicates "additional connected number".
+
+The exchange shall convert the connected number parameter field to an international number (if necessary) and set the nature of address indicator to "international number". The address presentation restricted indicator and the screening indicator shall be transferred transparently.
+
+If the generic number parameter field is received and its number qualifier indicates "additional connected number" and the numbering plan indicator is coded "ISDN (Telephony) numbering plan ([ITU-T E.164])", then the generic number parameter shall be treated in the same manner as the connected number parameter.
+
+##### **6.4.2.4.2 Exceptional procedures**
+
+No exceptional procedures identified.
+
+#### **6.4.2.5 Actions at the destination local exchange**
+
+##### **6.4.2.5.1 Normal operation**
+
+The exchange shall deliver the COL only if it was requested at call set-up. However, if it is included in the answer or connect message when it has not been requested it should not be considered as a protocol error and the call should be allowed to continue.
+
+In the case where a connected party is a PNX, the network sends the ISDN number and the DDI number of the extension as the COL if the extension digits are provided by the connected party. If the extension digits are not provided the network sends the ISDN default number. The default number is stored within the network but the value is agreed between the Administration and the customer concerned.
+
+When the COL is provided by the user or PNX, it might be verified or screened for validity by the network, i.e., the COL provided by the user is within the known number range for that user.
+
+- i) If the user provided COL is valid the connected number parameter field contains the COL in the address signals with the screening indicator set to "user provided verified and passed".
+- ii) If the user provided COL is not valid the destination exchange inserts the default number for the address signals with the screening indicator set to "network provided".
+- iii) If the user has a special arrangement with the network, that the user provided COL is not screened, then the destination local exchange shall disregard any value of the screening indicator, if received from the connected access.
+
+The connected number received from the called access shall be entered in the generic number parameter field. In this parameter field, the number qualifier indicator shall be set to "additional connected number", the screening indicator set to "user provided, not verified". The numbering plan indicator is coded "ISDN (Telephony) numbering plan ([ITU-T E.164])" if the numbering plan indicator received from the access signalling system indicates "unknown". The nature of address indicator shall be set to "international number" or "national (significant) number" as received from the connected access.
+
+In addition, the destination local exchange shall enter the default number associated with the connected user in the connected number parameter field. In this parameter field, the screening indicator shall be set to "network provided" and the nature of address indicator to "national (significant) number".
+
+- iv) If there is no agreement and the user provided COL is not valid, the destination exchange defaults to the network provided COL for the address signals of the connected number parameter field with the screening indicator set to "network provided".
+
+Optionally, a connected party sub-address may be included, if received from the called access, in the connected sub-address information element which is transported in the access transport parameter.
+
+If the COL cannot be transferred (because it is not allowed to be passed or because the national network cannot provide the number) then the connected number parameter should be included in the ANM or CON messages with the indication "presentation restricted" or "address not available" set as appropriate in the address presentation restriction indicator and set the screening indicator to "network provided".
+
+The numbering plan indicator of the connected number parameter field shall be set to "ISDN (Telephony) numbering plan ([ITU-T E.164])".
+
+The numbering plan indicator of the generic number parameter field shall be set to "ISDN (Telephony) numbering plan ([ITU-T E.164])" if the numbering plan indicator received from the access signalling system indicates "unknown".
+
+The address presentation restricted indicators of the connected number and the generic number parameter fields shall be set to "presentation allowed" or "presentation restricted" as received from the access signalling system.

+Flowchart of nodal signalling functions for COLP and COLR outgoing international gateway exchange. The process starts at 'Idle', receives 'CON or ANM', checks if COL is requested. If not, it omits party number fields. If requested, it checks if COL identity is in the CON number param field. If yes, it checks if the country code is the own country code. If yes, it removes the country code and adds a national prefix. If no, it adds an international prefix. If COL identity is not in the CON number param field, it checks if COL is in a generic number field. If yes, it again checks if the country code is the own country code and follows similar logic. If no, it sets PR=10 and SI=11. All paths lead to a final 'CON or ANM' and 'Idle' state.

+NOTE 1 – It is a function of the access signalling system to check if the COLP supplementary service is applicable and not to present presentation restricted numbers to the calling user.
+
+NOTE 2 – The request option is not supported by private networks (identity always included). The request procedure can only be used to obtain the connected line identity.
+
+NOTE 3 – This transition specifies additional processing to that described in Annex B of [ITU-T Q.764].

+## FOREWORD
+
+The CCITT (the International Telegraph and Telephone Consultative Committee) is a permanent organ of the International Telecommunication Union (ITU). CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988).
+
+Recommendation Q.731, § 8 was prepared by Study Group XI and was approved under the Resolution No. 2 procedure on the 4th of February 1992.
+
+## --- CCITT NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency.
+
+## Recommendation Q.731.8
+
+## STAGE 3 DESCRIPTION FOR NUMBER IDENTIFICATION SUPPLEMENTARY SERVICES USING SIGNALLING SYSTEM No. 7 – SUB-ADDRESSING (SUB)
+
+## 8 Sub-addressing (SUB)
+
+### 8.1 *Definition*
+
+The Sub-address supplementary service allows the called (served) user to expand his addressing capacity beyond the one given by the ISDN number.
+
+The stage 1 service description is given in Recommendation I.251.8 and the stage 2 functional capabilities and information flows are given in Recommendation Q.81, § 8. The stage 3 description of the sub-address supplementary service uses the ISDN user part protocol as defined in Recommendations Q.761 to Q.764 and Q.767.
+
+### 8.2 *Description*
+
+#### 8.2.1 *General description*
+
+The sub-address information is access significant information which is transported transparent through the network in the access transport parameter in the initial address message (IAM).
+
+#### 8.2.2 *Specific terminology*
+
+None.
+
+#### 8.2.3 *Qualification on the applicability to telecommunication services*

+# FOREWORD
+
+The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+ITU-T Recommendation Q.755 was prepared by the ITU-T Study Group XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993).
+
+# --- NOTES
+
+1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T) was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the IFRB have been replaced by the Radiocommunication Sector.
+
+In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms "CCITT, CCIR or IFRB" or their associated entities such as Plenary Assembly, Secretariat, etc. Future editions of this Recommendation will contain the proper terminology related to the new ITU structure.
+
+2 In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+# SIGNALLING SYSTEMS No. 7 PROTOCOL TESTS
+
+(Helsinki, 1993)
+
+# 1 Introduction
+
+The protocol testers may be used as an aid when testing the Message Transfer Part (MTP) and the Signalling Connection Control Part (SCCP) of Signalling System No. 7 (SS No. 7), either when performing validation testing of an implementation or compatibility testing between two implementations. The tester's main function is simulation of an ordinary user part or sub-system, as seen from the MTP or SCCP respectively, for the generation of test traffic.
+
+Recommendations I.320 and I.321 specify the ISDN protocol reference model to be used for N-ISDN and B-ISDN. User plane (U-plane), Control plane (C-plane) and Management plane (M-plane) are identified. The layering principles apply in each of these planes. The U-plane provides the user information flow transfer with associated controls. The C-plane handles the call and connection control information. The M-plane is divided into two portions, the Layer Management functions and the Plane Management functions. The Plane Management performs management functions related to a system as a whole, it provides coordination between all the planes and has no layered structure. The Layer Management plane contains Layer Management Entities (LME). Each of them provides management functions relating to resources and parameters residing in its own protocol entity. Layer Management handles the operation and maintenance information flows. The interface between adjacent layers within a plane and between LME and its associated layer have to be defined in terms of service primitives. The interface between the LMEs and Plane Management has not to be specified, it is implementation dependent.
+
+Thus the MT is contained in the LME of the MTP-3 (MTP-3 LME) and the ST is within the LME of the SCCP (SCCP LME). The service primitives between MTP-3 LME and the MTP-3, and between SCCP LME and the SCCP is described, as well as the procedures, the messages and the MT and ST substructures. The undefined primitives between the Plane Management (MIB) and the MT and ST are only required to activate/deactivate the concerned testing functions (see Figure 1).
+
+# 2 MTP tester (MT)
+
+The MT is connected to the MTP as a user part, i.e. identified by a service indicator. It generates Message Signal Units (MSUs) containing a serial number (and possibly additional information) in the Signalling Information Field (SIF). On reception of these messages a check is performed to verify that the messages are delivered according to the defined performance criteria for the MTP.
+
+## 2.1 Functions
+
+### 2.1.1 Objectives and scope
+
+The MT is:
+
+- a possible tool for validation testing when traffic generation is needed whilst performing tests. However, other traffic generators may be used and not all test cases may be covered with the MT when performing validation tests;
+- the preferred traffic generator for compatibility tests between different network operators. However, other traffic generators may be used for compatibility testing between different versions of the same system inside one national network;
+- a useful possible tool when performing network performance verification tests for SS No. 7 networks which are in service. If international network performance verification should be needed, it would be the preferred traffic generator.

+
+The diagram illustrates the internal configuration and management of a Signaling Point (SP) for SS No. 7. On the left, a vertical 'MIB' (Management Information Base) is shown. To its right, several functional blocks are stacked vertically, connected by a common horizontal bus structure. At the top, 'Part of OMAP' is connected to an 'AE' (Application Entity) containing 'LME', 'OMASE', and 'TCASE'. This AE is linked via 'SMSI' and 'OM-prim' to 'e.g. MAP' and 'Call Control application services'. The 'Call Control application services' block contains 'ISDN UP' and 'TUP', each with its own 'LME'. Below the top AE, there are two dashed boxes labeled '(Note 6)'. A connection point 'x' leads to the 'SCCP (Level 4)' block, which includes an 'ST' (Signaling Transfer) and 'LME'. Another connection point 'y' leads to the 'MTP (Levels 1-3)' block, which includes an 'MT' (Message Transfer) and 'LME'. Dashed lines labeled 'LMI' (Link Management Interface) connect the MIB and various LMEs. Dashed lines labeled 'AMI' (Alarm Management Interface) connect the top blocks. At the bottom right, a note states 'For communication between SS No. 7 nodes' with the reference 'T1143300-92/d01'.

+
+### 2.1.2 Main functions
+
+The main function is the generation of bidirectional test traffic, giving the possibility at the receiving node of analysing the received test traffic (e.g. detection of missequencing, duplication or loss of messages, verification of transfer delays ...). Errors may be introduced in the SS No. 7 network (by external means to the testers) during the transmission of test traffic.
+
+### 2.1.3 Architectural model
+
+The architectural model is as given in Figure 1.
+
+All procedures are located in the Layer Management Entity (LME), all other functions are located within the Management Information Base (MIB) and the Management Process (MP).
+
+### 2.1.4 Implementation
+
+Only one implementation mode is to be described, and this will perform message generation, “turn around”, verification and termination.
+
+### 2.1.5 Traffic modes
+
+There will be only one traffic mode, the “turn around” mode. However, the tester performing the “turn around” function will fulfil basic message verification such as sequence checking and message counting.
+
+### 2.1.6 Functional blocks
+
+Whilst keeping the single implementation mode, there are two functional roles which are identified during a test; the tester generating the traffic and the tester turning around the test messages. It is perfectly possible for a tester to be generating traffic towards one signalling point whilst performing the “turn around” role in another test to a different signalling point.
+
+#### 2.1.6.1 Generator
+
+The Generator role uses the services of various blocks within the MT. The test control function will confirm that the remote end is ready and able to start a test, then control the duration and termination of the test. The message generation function will then generate the appropriate traffic messages at the rate requested in the test set-up. The generator will also control the message lengths. The message verification function receives the messages returning from the turn around end and checks them for corruption, loss, missequencing and duplication. The MTP specific portion deals with generating the MTP transfer primitives and handling the incoming MTP primitives. The OMAP interface handles test requests from TMN, test supervision and control and the presentation and interpretation of test results.
+
+#### **2.1.6.2 Turn around**
+
+The turn around role uses the test control function to control the acceptance and supervision of a test. Test traffic arriving from the generator is checked by the message verification block, before being returned to the generator via the turn around function. The MTP specific portion again deals with the sending and receiving of MTP primitives. The OMAP interface deals with test acceptance, test control and the presentation and interpretation of results.
+
+### **2.1.7 Identification of test sequences**
+
+A particular test sequence is identified by the point codes and network indicators of the two testers involved. Thus it is only possible to have one test at a time running between two point codes. The GPC, the point code of the generating tester is included as an additional security feature.
+
+### **2.1.8 Message rate considerations**
+
+To secure delivery in sequence via MTP all test traffic messages use the identical code within the SLS-field. Thus they will use only one link of every linkset passed. This should be considered when defining the actual message rate. Using the same SLS-code after turn-around may or may not define the same links in the backward direction as in the forward direction as the load-sharing key is implementation dependent.
+
+## **2.2 Procedures**
+
+### **2.2.1 Test set-up**
+
+There are three possible phases during test set-up: test request, test acceptance and test refusal.
+
+#### **2.2.1.1 Test request**
+
+Once a test request has been received by the tester from OMAP a check will be made to ensure that no test already exists for the requested point code (turn around point code TPC). If a clash is detected an error is returned to OMAP with an appropriate reason, the test already in place will not be affected. If a valid request is received then the necessary counters are initialized, and a guard timer is started to control test set-up T1. A test request message is then sent to the TPC. The information provided by the OMAP will include an indication of the required response to the receipt of an MTP status with cause network congestion. The conditions applying to the setting of this indication are to be defined within Recommendation Q.751. The default action is to stop the test. It may be specifically requested by OMAP to report congestion indications, but continue the test. The indication is passed in the test request message and must be accepted by the turn around tester.
+
+NOTE – This procedure should only be used with extreme caution.
+
+#### **2.2.1.2 Test acceptance**
+
+##### **2.2.1.2.1 By the turn around tester**
+
+On reception of a test request message a check is performed to ensure that a test with the originating tester is not already in progress. If a test is found to be in progress then a test termination request message is sent, a report is made to OMAP and the original test is terminated.
+
+If no test is found to be in progress then the turn around tester will request from OMAP to start a test from the respective point code. On receiving a negative response from OMAP (e.g. due to local conditions), a test refusal message is sent. A positive response will initiate the sending of a test acceptance message and the initialization of the necessary counters. OMAP also specifies criteria for test termination. See 2.2.2.1 apart from a).
+
+##### **2.2.1.2.2 By the generator**
+
+The reception of a test acceptance message by the generator will cause the termination of the set-up timer T1. The OMAP will be informed that a test is in progress, the generation of test traffic will begin.
+
+#### **2.2.1.3 Test refusal**
+
+If a test refusal message is received then the set-up timer T1 is terminated, any counters initialized will be cleared and a report is made to OMAP.
+
+#### **2.2.1.4 Timer T1 Expiry**
+
+If timer T1 expires then any counters initialized will be cleared and a report is made to OMAP. It is assumed that the test request was lost and any subsequent test acceptance or refusal messages will be dealt with as an unexpected message.
+
+### **2.2.2 Test duration**
+
+#### **2.2.2.1 At the generator**
+
+On receipt of a test acceptance message the test duration timer T2 is started, the messages are generated according to the rate information supplied by OMAP. As each message is sent, the Messages Sent count is incremented. The value of this count is given as the serial number field within the test traffic message. The need for a supervision timer for each message is implementation dependent. The generating tester may place further information (e.g. a time stamp) in the additional data field of the test traffic message, this is not looked at by the turn around tester, however the additional data field should contain sufficient filler octets (coded all zeros) to give an overall message length as requested during test set-up by OMAP.
+
+When test traffic messages are received at the generator, the messages are checked by comparing the Generating Point Code field (GPC) with the tester's own point code. As messages are terminated at the MT the messages received counter is incremented, and the message serial number is checked as a means of sequence validation. Any further checking may be done using the information in the additional octets field.
+
+#### **2.2.2.2 At the turn around tester**
+
+Incoming messages are checked as in the generating tester. If the GPC is not the tester's own point code, and a current test to the relevant point code is in existence, then the messages are turned around. The messages received counter is incremented and the serial number checked for missequencing. The OPC and DPC of the MTP transfer indication are then swapped and the message formed into an MTP transfer request.
+
+#### **2.2.2.3 Response to missequencing**
+
+If on checking the message serial number an error in sequence is detected then a report is made to OMAP which includes the message serial number and any additional filler octets. However, to stop a message loss causing all remaining messages to be seen as missequenced the message counter must be reset to the serial number of the message detected as missequenced.
+
+### **2.2.3 Termination**
+
+#### **2.2.3.1 By the generator**
+
+The test ends by either:
+
+- a) expiry of T2 (where the value of T2 was specified during test set-up by OMAP); or
+- b) congestion indication if OMAP has not specifically instructed it to be ignored; or
+- c) specific request from OMAP.
+
+The test termination procedure involves the sending of a test termination request message and the starting of a test termination timer T3.
+
+On receipt of a test termination acknowledgment message the test results and reason for test end are sent to OMAP and the counters are cleared. If timer T3 expires then the local OMAP is informed.
+
+If a test termination request message is received then a test termination acknowledgement message is sent, the test results and reason for end are sent to OMAP and the counters are cleared.
+
+#### **2.2.3.2 By the turn around tester**
+
+The procedure for terminating a test by the turn-around tester is the same as at the generator, except that T2 expiry is not possible. After sending a test termination request the turn-around tester continues its turn-around function until it either receives a test termination acknowledgement or T3 expires. If T3 expires, the local OMAP is informed.
+
+#### **2.2.3.3 Test termination acknowledgement**
+
+Upon receipt of a test termination request, the local test is stopped and a test termination acknowledgement is sent.
+
+### **2.2.4 Reaction to MTP management primitives and MTP restart**
+
+#### **2.2.4.1 MTP pause**
+
+If the affected point code is currently performing the generator function in one of the current tests then the test is paused, no more messages are generated and the timers and counts are held. If a local request to terminate the test whilst in this held state is received then a notification of the inability to terminate the test is returned to OMAP and the test termination procedure is started, however the test termination procedure will be held until the remote end becomes available (i.e. receipt of an MTP resume or an MT message from the unavailable tester).
+
+If the MTP pause is received by a tester performing the turn-around function for the affected point code then no action is necessary, except where the local OMAP requests to terminate the test. In this case OMAP is again informed, the test termination procedure remains started but held until the remote end becomes available.
+
+#### **2.2.4.2 MTP resume**
+
+If a local test termination request has been received for the affected point code during the period the remote tester was unavailable, then an MTP resume will release the test termination procedure.
+
+If there is a held test to the affected point code (i.e. the affected point code is the TPC) then the test will resume.
+
+Otherwise the MTP resume is ignored.
+
+#### **2.2.4.3 MTP status**
+
+The MTP status primitive contains two parameters, the affected point code and a cause.
+
+The cause may be:
+
+- signalling network congestion (a national option allows a level to be included);
+- remote user unavailable;
+- remote user unequipped.
+
+On receiving remote user unavailable or remote user unequipped for a point code currently in use by the tester, the MT will stop sending messages to the destination, and inform OMAP. The normal test termination procedure will not take place.
+
+- Signalling network congestion indication.
+
+If an MTP status is received with cause network congestion, for a point code currently involved in a test, then the congestion response indication provided by OMAP will determine the tester's response to this indication. The default action is to stop the test and report to OMAP. If the test request specified "report congestion indication but continue test", the tester will report congestion indication to OMAP, but continue the test.
+
+#### **2.2.4.4 MTP restart**
+
+If the tester detects a local MTP restart, then the test termination procedure is started for all current tests, but held until the restart is finished.
+
+NOTE – Where the termination procedure is held the timer T3 is also held.

+- T3 5-10 sec This timer governs the frequency at which test termination request messages are sent.
+
+### 2.3.5 Interface requirements
+
+The description of the interface between the MT and OMAP is outlined in Table 1.
+
+There will be additional notifications from the tester to OMAP; these contain the appropriate information. Table 1 is only a guide as this interface is not for specification, (see Recommendation Q.751).

+## **SIGNALLING SYSTEM No. 7 – APPLICATION TRANSPORT MECHANISM: TEST SUITE STRUCTURE AND TEST PURPOSES (TSS & TP)**
+
+## **Summary**
+
+This Recommendation contains the conformance test specification for ISUP'97 application transport mechanism. The main body of this Recommendation presents the requirements regarding the chosen test method, the test suite structure and the test purposes.
+
+### **Source**
+
+ITU-T Recommendation Q.765 *bis* was prepared by ITU-T Study Group 11 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on 3 December 1999.
+
+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+
+This Recommendation contains the validation (conformance) test specification for the Application Transport Mechanism defined in Recommendation Q.765 [1]. This Recommendation applies only to exchanges having implemented the ISUP'97 protocol specification for the Application Transport Mechanism of the exchange. It is applicable for validation testing of all types of exchanges as defined in the ISUP'97 protocol specification. It does not deal with compatibility testing.
+
+The main body of this Recommendation presents the Test Suite Structure and Test Purposes (TSS & TP) for the Application Transport Mechanism (APM).
+
+Annex A provides the Protocol Implementation Conformance Statement (PICS) proforma for the Application Transport Mechanism defined in compliance with the relevant requirements and in accordance with the guidance given in ISO/IEC 9646-7 [8]. This statement indicates which capabilities and options of a telecommunication specification have been implemented. It is necessary for evaluating the conformance of a particular implementation.
+
+The supplier of an implementation that is claimed to comply with the reference specification for the Signalling System No. 7, Application Transport Mechanism [1], is required to complete a copy of the PICS proforma provided in Annex A.

+
+## 5.1 Identification of the system and implementation under test
+
+The System Under Test (SUT) is an exchange. The Implementation Under Test (IUT) is the ISUP'97 implementation in this exchange, mainly the part responsible for the Application Transport Mechanism (APM), as shown in Figure 1.
+
+![Diagram of the system under test (SUT) showing the hierarchy of protocols. The SUT (Exchange) contains the IUT, which contains APM_user, APM, and ISUP Basic Call ISUP'97. Arrows show the flow of information between these layers and external ISUP connections.](b8661c6c54f72ecc7ff6cb05e47b2891_img.jpg)
+
+The diagram illustrates the system under test (SUT) architecture. The SUT is represented by a large outer rectangle labeled 'Exchange' at the top and 'SUT' at the bottom right. Inside the SUT is a smaller rectangle labeled 'IUT' at its bottom right. Within the IUT, there are three stacked boxes: 'APM\_user' at the top, 'APM' in the middle, and 'ISUP Basic Call ISUP'97' at the bottom. A vertical double-headed arrow labeled 'APM\_user Information Flow' passes through the APM\_user box, extending above the Exchange boundary. Two horizontal double-headed arrows labeled 'ISUP' enter the IUT from the left and right sides, pointing towards the ISUP Basic Call ISUP'97 box. A small code 'T11103520-99' is located at the bottom right of the diagram.

+
+The protocol functions for the Application Transport Mechanism relates to the signalling associations with a bearer (ISUP). Therefore the defined ISUP Basic Call and its associated formats and codes are required to support the Application Transport Mechanism. The following main subjects have to be considered in this area:
+
+- a) APM-user Protocol Control (APM-user Application Service Element).
+- b) Application Transport Mechanism Protocol Control (APM Application Service Element).
+- c) ISUP Basic Call (ISUP Application Service Element).
+
+The APM user primitives or APM user information flow can be observed through the individual reference point defined for each APM user or application process, respectively. In case of a PSS1 ASE (APM-user ASE for the VPN application) for example, the Q reference point is applicable.
+
+The ISUP signalling protocol can be observed on the SS No. 7 link on the Network Nodal Interface (NNI).
+
+From the ISUP/APM reference standard several types of exchanges (or roles) can be identified:
+
+- Local Exchanges in case of a Public Initiating Node (PIN) or a Public Addressed Node (PAN) with several APM-users.
+- Transit Exchanges in the role of a PIN or PAN with several APM-users.
+- National Transit Exchanges as defined in Recommendation Q.761.
+
+The National Transit Exchanges pass on the APM messages without checking the messages. In the case of a PIN or PAN the messages related to an APM call are checked according to the corresponding APM user. If the peer APM user is not residing in the exchange the call is passed on to the destination or to the addressed location (PAN).
+
+## **5.2 ATM and testing configuration for ISUP'97 – Application Transport Mechanism**
+
+The Abstract Test Method (ATM) chosen for the Application Transport Mechanism specification is the distributed multi-party test method. The ATM is defined at an appropriate level of abstraction so that the test cases may be specified appropriately, without adding restrictions to the implementation under test.
+
+The ATS is written in concurrent TTCN.
+
+## **5.3 Local exchanges – PIN/PAN**
+
+As mentioned above, the IUT can be tested within different configurations. The following text describes the test configuration for the IUT where the software for ISUP V3 and also the APM part reside in a local exchange.
+
+Figure 2 shows the logical test components of the adopted test configuration. The main test component is located on the right side of the IUT; it contains the ISUP part. On the left side there is a parallel test component which covers the APM part.
+
+![Figure 2/Q.765 bis – APM test configuration for local exchanges. The diagram shows a test setup with two main vertical paths. The left path consists of a 'TCP' block connected to a 'UT' (Upper Tester) block. Inside the 'UT' block are 'Application Process' and 'AI X'. Below the 'UT' block is an 'IUT' (Implementation Under Test) block, which contains 'SP A'. A double-headed arrow labeled 'UAX' connects the 'UT' block to the 'IUT' block. The right path consists of an 'LT' (Lower Tester) block connected to a 'SP B' block. Inside the 'LT' block is an 'ISUP link'. Below the 'SP B' block is a 'LAB' block. A double-headed arrow labeled 'LAB' connects the 'SP B' block to the 'LAB' block. Both the 'IUT' block and the 'LAB' block are connected to a common 'Network service provider' block at the bottom. The text 'T11103530-99' is located at the bottom right of the diagram.](d4af765160d04ecef538e5066006dc77_img.jpg)

+
+**Figure 2/Q.765 bis – APM test configuration for local exchanges**
+
+To observe and control the message flow on the ISUP and APM side for each side a Point of Control and Observation (PCO) is needed. The PCO for the ISUP link is abbreviated with an "L" followed by two letters indicating the interface. The naming convention for the PCO, specifying the Upper Tester, is the same but having an "U" instead of the "L" as the first character.
+
+There is no defined interface from ISUP (the IUT) towards the APM user side. For testing the primitives specified in [1], which are sent between the APM Application Service Element (ASE) and the APM user ASE, the above-mentioned Upper Tester (UT) is needed. It is therefore necessary to make use of an Application Interface (AI) including a PCO and to use the specified primitive names given in [1] for the Abstract Service Primitives (ASPs) to be used on this PCO.
+
+The LAB PCO is used by the Lower Tester (LT) to control and observe the ISUP on the signalling to the exchange. The other UAX PCO is needed to check if the expected primitives for the APM user are correctly generated by the exchange. The PDUs on this PCO are chosen at an appropriate level of abstraction.
+
+The Test Coordination Procedures (TCP) allow for communication between the testers. The test components are mostly implicitly coordinated (asynchronously); the TCPs are only used when it is necessary to obtain the verdict from the parallel test component.
+
+This configuration to test the local exchanges is presented in Figure 2.
+
+## 5.4 Transit exchanges – PIN/PAN
+
+For this configuration the same rules and definitions are applicable as used in 5.3, Local exchanges.
+
+## 5.5 Transit exchanges – ISUP
+
+The configuration proposed for testing transit exchanges is shown in Figure 3. In order to test the protocol and functionality of transit exchanges, one needs to consider the incoming and outgoing side of the SUT.
+
+![Diagram of APM test configuration for transit exchanges. It shows two Lower Testers (LT) connected to a central Implementation Under Test (IUT) via ISUP links. The LT on the left is connected to SP C, which is connected to a Network service provider via LAC. The LT on the right is connected to SP B, which is connected to a Network service provider via LAB. The IUT is connected to SP A, which is also connected to the Network service provider. Above the IUT is an Upper Tester (UT) with an Application Process (AIX) connected via UAX. The LTs are also connected to the UT via TCP.](af7916c89a458fdab6c3f443217388ae_img.jpg)

The IUT is connected to SP A, which is also connected to the Network service provider. Above the IUT is an Upper Tester (UT) with an Application Process (AIX) connected via UAX. The LTs are also connected to the UT via TCP.

+
+The IUT is observed and controlled from two ISUP links with associated circuits. The Points of Control and Observation (PCO) are labelled LAB on the one side and LAC on the other.
+
+The LAB and LAC PCOs are used by the Lower Testers (LT) for controlling the ISUP signalling links.
+
+The underlying network service provider is the Message Transfer Part (MTP) protocol as specified in Recommendations Q.701 to Q.707.
+
+The Test Coordination Procedures (TCP) allow for communication between the testers. The test components are mostly implicitly coordinated (asynchronously); the TCPs are only used when it is necessary to obtain the verdict from the parallel test component.
+
+The Upper Tester (UT) and its UAX PCO is not used in this configuration.

+# 7 Test Purposes (TP)
+
+## 7.1 Introduction
+
+For each test requirement a Test Purpose (TP) is defined.
+
+## 7.2 Test Purpose (TP) naming convention
+
+Test Purposes are numbered ascending within each group. Groups are organized according to the TSS down to the last but one level. The classification in the V/I groups is done by the inclusion of V or I in the test case name. Additional qualifiers, in form of lower case letters, are added to identify variants within one generic test case (see Table 1).

+**Table 1/Q.765 bis – TP Identifier naming convention scheme**

+
+### 7.2.1 Source of test purpose definition
+
+The test purposes cover validation testing aspects and were developed within ETSI.
+
+### 7.2.2 Test purpose structure
+
+The test purpose structure overlaps with the Test Suite Structure (TSS).
+
+Test purposes that test normal behaviour have been grouped in the **V** – Valid behaviour group.
+
+Test purposes that test the IUT behaviour in situations that are not normal operation have been grouped in the **I** – Inopportune stimulus group.
+
+## 7.3 Test purposes for the Signalling System No. 7, Application Transport Mechanism (APM)
+
+All of the following test purposes belong to the main group ISUP\_97\_APM. Each test purpose is presented in a separate table. The first row of the table contains the following items:

+The next row defines the test purpose itself, each having a *title* in *italics* and a text body.
+
+The ISUP **messages**, **parameters**, the APM **primitives** are highlighted in **bold** to ease the readability.
+
+In order to check the specified behaviour for some test purposes, a special prerequisite test condition has to be fulfilled. If such a condition is needed, it is presented after the test purpose under the heading "Pre-test conditions".

+# 8 Test coverage
+
+The test purposes defined in this test specification cover most main capabilities of the Application Transport Mechanism (APM). For this purpose, the essential components of the Q.765 specification, i.e. the Application Transport Mechanism protocol control (APM Application Service Element), the ISUP Basic Call (ISUP Application Service Element), the Unidentified Context and Error Handling control (UCEH ASE), and the associated procedures are tested.
+
+A list containing the number of test purposes for the related requirements of Recommendation Q.765 is provided in Table 2.
+
+Whenever it was possible, the test purposes have been described such that they bundle related requirements of Recommendation Q.765. Due to this fact, a test purpose may lead to implementing several test cases for the ATS.
+
+The test purposes concentrate on valid behaviour. This means that there is no invalid behaviour test purposes specified. An expansion of the invalid behaviour test purposes is left for further study.

+# 9 Conformance to the PICS proforma specification
+
+A PICS proforma that conforms to this PICS proforma specification shall be technically equivalent to Annex A, and shall preserve the numbering and ordering of the items in Annex A.
+
+A PICS that conforms to this PICS proforma specification shall:
+
+- describe an implementation which is claimed to conform to ISDN User part 1997 (ISUP'97) reference specification [1] to [3];
+- be a conforming PICS proforma which has been completed in accordance with the instructions for completion given in A.1;
+- include the information necessary to uniquely identify both the supplier and the implementation.
+
+# ANNEX A<sup>1</sup>
+
+## PICS proforma for ISDN User Part 1997 (ISUP'97) – Signalling System No. 7, Application Transport Mechanism
+
+### A.1 Instructions for completing the PICS proforma
+
+The supplier of the implementation shall complete the PICS proforma in each of the spaces provided. If necessary, the supplier may provide additional comments separately.
+
+More detailed instructions are given at the beginning of the different subclauses of the PICS proforma.
+
+---
+
+<sup>1</sup> Copyright release for PICS proforma
+
+Users of this Recommendation may freely reproduce the PICS proforma in this annex so that it can be used for its intended purpose, and may further publish the completed PICS.
+
+#### A.1.1 Purposes and structure
+
+The purpose of this PICS proforma is to provide a mechanism whereby a supplier of an implementation of the requirements defined in ISDN User Part 1997 (ISUP'97) reference specification [1] to [3] may provide information about the implementation in a standardized manner.
+
+The PICS proforma is subdivided into subclauses for the following categories of information:
+
+- instructions for completing the PICS proforma;
+- identification of the implementation;
+- identification of the reference protocol specification;
+- PICS proforma tables (containing the global statement of conformance).
+
+#### A.1.2 Abbreviations and conventions
+
+The PICS proforma contained in this annex is composed of information in tabular form in accordance with the guidelines presented in ISO/IEC 9646-7 [8].
+
+##### Item column
+
+It contains a number that identifies the item in the table.
+
+##### Item description column
+
+It describes each respective item (e.g. parameters, timers, etc.).
+
+##### Reference column
+
+It gives reference to the ISUP'97 specification for the Application Transport Mechanism [1], except where explicitly stated otherwise.
+
+##### Status column
+
+The following notations, defined in ISO/IEC 9646-7 [8], are used for the status column:
+
+- m mandatory – The capability is required to be supported.
+- n/a not applicable – In the given context, it is impossible to use the capability. No answer in the support column is required.
+- o optional – The capability may or may not be supported.
+- o.i qualified optional – For mutually exclusive or selectable options from a set. "i" is an integer which identifies a unique group of related optional items and the logic of their selection which is defined immediately following the table.
+- ci conditional – The requirement on the capability ("m", "o" or "n/a") depends on the support of other optional or conditional items. "i" is an integer identifying a unique conditional status expression that is defined immediately following the table. For nested conditional expressions, the syntax "IF ... THEN (IF ... THEN ... ELSE...) ELSE ..." shall be used to avoid ambiguities. If an ELSE clause is omitted, "ELSE n/a" shall be implied.
+
+NOTE – Support of a capability means that the capability is implemented in conformance to the ISUP'97 specification [1] to [3].
+
+##### Support column
+
+The support column shall be filled in by the supplier of the implementation. The following common notations, defined in ISO/IEC 9646-7 [8], are used for the support column:
+
+- Y or y Supported by the implementation.
+- N or n Not supported by the implementation.
+- N/A or – No answer required (allowed only if the status is N/A, directly or after evaluation of a conditional status).
+
+##### **Values allowed column**

+This column contains the values or the ranges of values allowed.
+
+##### **Values supported column**
+
+The support column shall be filled in by the supplier of the implementation. In this column the values or the ranges of values supported by the implementation shall be indicated.
+
+##### **References to items**
+
+For each possible item answer (answer in the support column) within the PICS proforma a unique reference exists. It is defined as the table identifier, followed by a slash character "/", followed by the item number in the table. If there is more than one support column in a table, the columns shall be discriminated by letters (a, b, etc.) respectively.
+
+Example 1: A.5/4 would indicate the reference to the answer of item 4 in Table A.5 of Annex A.
+
+Example 2: A.6/3b would indicate the reference to the second answer (i.e. in the second support column) of item 3 in Table A.6 of Annex A.
+
+### **A.2 Identification of the implementation**
+
+Identification of the Implementation Under Test (IUT) and the system in which it resides – the System Under Test (SUT) should be filled in so as to provide as much detail as possible regarding version numbers and configuration options.
+
+The product supplier information and client information should both be filled in if they are different.
+
+A person who can answer queries regarding information supplied in the ICS should be named as the contact person.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+## MTP level 2 test specification
+
+# 1 Introduction
+
+This Recommendation contains a set of detailed tests of signalling system No. 7 MTP level 2 protocol. These tests intend to validate the protocol specified in ITU-T Rec. Q.703.
+
+This Recommendation conforms to ITU-T Rec. Q.780 which describes the basic rules of the Test Specification. In addition, the conditions which are specific to level 2 tests are described in the following clauses.
+
+## 2 General principles of level 2 tests
+
+## 2.1 Presentation of test descriptions
+
+The level 2 tests aim at testing the level 2 protocol conformance in a given implementation.
+
+Each test description indicates in the "type of test" column; "Validation" (VAT) or "Compatibility" (CPT).
+
+Although signal units are transmitted and received continuously on level 2, only the signal units which cause and/or indicate the changes of level 2 status are shown in the EXPECTED SIGNAL UNIT SEQUENCE column of each test description.
+
+## 2.2 Presentation of the test list
+
+These tests as a whole, aim at a complete validation of the level 2 protocol without redundancies. Each test is described as simply as possible to check precisely each elementary function of the protocol, which is referred in the columns "reference", "title" and "subtitle" of each test description.
+
+This list is presented in the form of a succession of tests. The presentation order is essentially functional. However, the operator performing these tests may change this order, taking into account some other practical criteria such as: use pre-test conditions to order the list, the end of a given test may be the pre-test condition of another test.
+
+## 3 Test configuration
+
+A single link will be used for level 2 tests. Figure 1 shows a single link between SP A and SP B. Test specifications are written to test the level 2 of the SP A.
+
+![Diagram of test configuration showing SP B and SP A connected by a link. SP B has Tx and Rx ports. SP A has Rx and Tx ports and is labeled '(under test)'. The link is labeled 'Link 1 - 0 (Note)'. A small diagram shows two parallel lines with an oval in the middle representing the link. The text 'T1157160-93' is near SP A.](06da11ab76cacc38bbcd714e437797ea_img.jpg)

+# NOTES
+
+1 ITU-T Recommendation Q.783 was published in Fascicle VI.9 of the *Blue Book*. This file is an extract from the *Blue Book*. While the presentation and layout of the text might be slightly different from the *Blue Book* version, the contents of the file are identical to the *Blue Book* version and copyright conditions remain unchanged (see below).
+
+2 In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+# **TUP TEST SPECIFICATION**
+
+## **1 Introduction**
+
+This Recommendation contains a set of detailed tests for the Signalling System No. 7 Telephony User Part (TUP). These tests are intended to validate the protocol specified in Q.721-Q.724 Recommendations. This Recommendation conforms to Q.780 Recommendations which describes the basic rules of the test specification.
+
+## **2 General principles of TUP tests**
+
+The TUP tests aim at testing TUP protocol conformance in a given implementation. The tests are described as "Validation" tests or "Validation" and "Compatibility" tests. Each test description indicates in the field "type of test" whether the test is "Validation" or "Validation" and "Compatibility". As the TUP also describes the required call control actions resulting from TUP message transfer the TUP tester also checks the result of those call control actions, e.g. that speech/information transfer is possible.
+
+## **3 Test configuration**
+
+A stable signalling relation is required between "SP A" and "SP B" in order to effectively test the TUP. In addition telephony circuits are required for some of the tests.
+
+## **4 TUP test list**
+
+All tests may be validation tests. Tests marked "\*" are compatibility tests. Tests marked "fs" are for further study.

+# FOREWORD
+
+The CCITT (the International Telegraph and Telephone Consultative Committee) is a permanent organ of the International Telecommunication Union (ITU). CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988).
+
+Recommendation Q.785 was prepared by Study Group XI and was approved under the Resolution No. 2 procedure on the 10<sup>th</sup> of September 1991.
+
+# --- CCITT NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency.
+
+# **ISUP PROTOCOL TEST SPECIFICATION FOR SUPPLEMENTARY SERVICES**
+
+## **1 Introduction**
+
+This Recommendation contains a detailed set of tests for the supplementary services supported by Signalling System No. 7 Integrated Services Digital Network User Part (ISUP).
+
+Details of the supplementary services supported by ISUP can be found in *Blue Book* (1988) Recommendation Q.730. It should be noted that this test Recommendation covers those services which can be regarded as stable and clearly specified in *Blue Book* (1988) Recommendation Q.730.
+
+This Recommendation also covers supplementary services supported by Recommendation Q.767.
+
+The basic rules for the test specification can be found in Recommendation Q.780.
+
+## **2 Objective of the test specification**
+
+The objective of this test specification is to check that the ISUP protocol supported by a given implementation has the ability to correctly convey the necessary signalling information to support the supplementary services specified in *Blue Book* (1988) Recommendation Q.730 and Recommendation Q.767 (1991). Therefore this test list only covers areas of supplementary services where there is a direct impact on the ISUP protocol. However some call control functions are also verified, i.e. the transfer of speech/information is possible.
+
+It should be noted that this test specification does not attempt to test the operation of the supplementary services (end-to-end function tests), as these tests are outside the scope of this test specification.
+
+This test specification does not intend to provide exhaustive testing of *Blue Book* (1988) Recommendation Q.730 and Recommendation Q.767 (1991) supplementary services, but does intent to provide a reasonable level of confidence that the protocol required to support *Blue Book* (1988) Recommendation Q.730 and Recommendation Q.767 (1991) supplementary services has been implemented at a signalling point.
+
+This test specification does not address interactions between supplementary services.
+
+## **3 General principles of tests**
+
+The tests are described as “validation” tests or “validation” and “compatibility” tests. Each test description indicates in the field “type of test” whether the test is a “validation” (VAT) or a “validation” and “compatibility” (VAT & CPT) test. In addition to protocol testing, some call control functions are also checked, e.g. that the transfer of speech/information is possible.
+
+The test specification assumes a tested MTP for compatibility tests.
+
+## **4 Test environment**
+
+### **4.1 *Signalling relation***
+
+A stable signalling relation is required between “SP A” and “SP B” in order to carry out effective tests. In addition telephony circuits are required for some of the tests.
+
+### 4.2 Configuration
+
+Only one configuration is required for the performance of these tests. This is shown in Figure 1/Q.785.

+
+### 4.3 Provision of stimulus at a signalling point
+
+This test specification requires the setting of various ISUP parameters at both the SP A (SP under test) and SP B. The setting of these parameters should be performed by an “appropriate stimulus” at the appropriate SP.
+
+No attempt is made in this Recommendation to specify the form of the “appropriate stimulus”, but instead the functional requirements are stated in general terms.

+The stimulus should be capable of setting the appropriate fields, parameters, and indicators in the ISUP *Blue Book* (1988) Recommendation Q.763 in the correct manner to support the supplementary services of *Blue Book* (1988) Recommendation Q.730. This equally applies to the amendments made by Recommendation Q.767 (1991) to *Blue Book* (1988) Recommendation Q.763 and to the supplementary services as described in Recommendation Q.767 (1991).
+
+It should be observed that depending on a number of factors the functions of the “appropriate stimulus” could be performed by various mechanisms. A number of possibilities are listed below :
+
+The stimulus could be:
+
+- i) an intrinsic part of a signalling point;
+- ii) provided by a network connected to the signalling point;
+- iii) provided by a “test box” connected to the signalling point;
+- iv) provided by exchange data set at the signalling point;
+- v) provided by user-network signalling.
+
+This list is not intended to be exhaustive. The choice of stimulus is a matter for the Administration concerned and does not necessarily require bilateral agreement.
+
+### 4.4 Checking of correct reception of parameters at signalling point under test
+
+This test specification requires the checking of the correct reception of various ISUP parameters at SP A (SP under test).
+
+No attempt is made in this Recommendation to specify how to perform this function, however depending on a number of factors the function of the “checking of receiving correctly of messages and parameters” could be performed by various mechanisms. A number of possibilities are listed below.
+
+The check could be performed by:
+
+- i) an intrinsic part of the SP A;
+- ii) a network connected to SP A;
+- iii) a “test box” connected to SP A;
+- iv) monitoring/printout at the SP A;
+- v) monitoring of the messages and information elements at the user-network interface.
+
+The list is not intended to be exhaustive. The choice of the method is a matter for Administration concerned and does not necessarily require bilateral agreement.
+
+### 4.5 *Check table*
+
+Many test scripts within the test specification include a check table. The check table lists specific indicators which must be checked.
+
+The check table does not necessarily include all the parameters and indicators that should be carried within any message.
+
+## 5 **ISUP protocol test list for supplementary services**

+## FOREWORD
+
+The CCITT (the International Telegraph and Telephone Consultative Committee) is a permanent organ of the International Telecommunication Union (ITU). CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988).
+
+Recommendation Q.81, §§ 3 and 5 was prepared by Study Group XI and was approved under the Resolution No. 2 procedure on the 10th of September 1991.
+
+## --- CCITT NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency.
+
+## **STAGE 2 DESCRIPTION FOR NUMBER IDENTIFICATION SUPPLEMENTARY SERVICES**
+
+*(revised 1991)*
+
+## **3 Calling Line Identification Presentation (CLIP) and Calling Line Identification Restriction (CLIR)**
+
+### **3.1 Scope**
+
+This Recommendation defines the stage 2 of the integrated services digital network (ISDN) as provided by the telecommunications operators for the Calling Line Identification Presentation (CLIP) and Calling Line Identification Restriction (CLIR) supplementary services. Stage 2 identifies the functional capabilities and the information flows needed to support the service description. The stage 2 description also identifies user operations not directly associated with a call (see Recommendation I.130 [1]).
+
+This Recommendation is defined according to the methodology specified in Recommendation Q.65 [2].
+
+This Recommendation does not formally describe the relationship between these supplementary services and the basic call but, where possible, this information is included for guidance.
+
+In addition, this Recommendation does not specify the requirements where the service is provided to the user via a private ISDN. This Recommendation does not specify the requirements for the allocation of defined functional entities within a private ISDN; it does however define which functional entities may be allocated to a private ISDN.
+
+This Recommendation does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.
+
+The CLIP supplementary service provides the called party with the possibility to receive identification of the calling party.
+
+The CLIR supplementary service enables the calling party to prevent presentation of its ISDN number to the called party.
+
+The CLIP and CLIR supplementary services are applicable to all telecommunication services.
+
+This Recommendation is applicable to the stage 3 Recommendations for the ISDN CLIP and CLIR supplementary services, as defined in Recommendation I.130 [1].
+
+### **3.2 References**
+
+These references are cited at the appropriate places in the text and the publications are listed hereafter. Dated references, subsequent amendments to, or revisions of any of these publications apply to this Recommendation only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.

+## ANNEX A (to § 3 of Recommendation Q.81)
+
+#### **Two calling-line-identities delivery option**
+
+#### A.1 *Scope*
+
+This annex specifies the additional procedures of the CLIP supplementary service that may be supported as a national network option.
+
+These national procedures shall have no impact and shall place no requirements whatsoever on the provision and operation of the CLIP supplementary service defined in this Recommendation by public ISDNs that do not support these additional procedures, nor on the interchangeability of terminals.
+
+#### A.2 *Additional procedures of FE4*
+
+If the procedures for delivery of the calling line identity as described in § 3.8 (SDL diagram for FE4) apply and the screening indicator is set to “user provided not screened”, then the FE4 shall send the second calling line identity immediately following the first calling line identity. The second calling line identity shall be the default calling line identity of the access of the calling party. The second calling line identity shall be provided according to procedures described in this Recommendation.
+
+In all other cases, only the first calling line identity shall be sent.
+
+## 5 Connected Line Identification, presentation and restriction (COLP and COLR)
+
+### 5.1 Scope
+
+This Recommendation defines the stage 2 of the integrated services digital network (ISDN) as provided by public telecommunications operators for the Connected Line Identification Presentation (COLP) and Connected Line Identification Restriction (COLR) supplementary services. Stage 2 identifies the functional capabilities and the information flows needed to support the service description. The stage 2 description also identifies user operations not directly associated with a call (see Recommendation I.130 [1]).
+
+This Recommendation is defined according to the methodology specified in Recommendation Q.65 [2].
+
+This Recommendation does not formally describe the relation between these supplementary services and the basic call but, where possible, this information is included for guidance.
+
+In addition, this Recommendation does not specify the requirements where the service is provided to the user via a private ISDN. This Recommendation does not specify the requirements for the allocation of defined functional entities within a private ISDN; it does however define which functional entities may be allocated to a private ISDN.
+
+This Recommendation does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.
+
+The COLP supplementary service provides the calling party with the possibility to receive identification of the connected party.
+
+The COLR supplementary service enables the connected party to prevent presentation of its ISDN number to the calling party.
+
+The COLP and COLR supplementary services are applicable to all telecommunication services.
+
+This Recommendation is applicable to the stage 3 standards for the ISDN COLP and COLR supplementary services. The term "stage 3" is defined in Recommendation I.130 [1].

The diagram shows a sequence of five functional entities (FE1 to FE5) and their corresponding call control (CC) or call connection (CCA) components. FE1 is connected to FE2 via interface r\_a (top) and r\_1 (bottom). FE2 is connected to FE3 via interface r\_b (top) and r\_2 (bottom). FE3 is connected to FE4 via interface r\_c (top) and r\_2 (bottom). FE4 is connected to FE5 via interface r\_d (top) and r\_3 (bottom). The bottom row consists of CCA, CC, CC, CC, and CCA blocks. A small code 'T1126330-90' is visible at the bottom right of the diagram.

If 'No', it leads to 'Note 1' (920). If 'Yes', it asks 'Any info. about COL. id. available?' (921). If 'No', it leads to 'SET PI = number not available' (921). If 'Yes', it asks 'Any presentation restrictions?' (922). If 'Yes', it leads to 'Override category?' (922). If 'No', it leads to 'Include received PI and SI' (922).

The 'Not subscribed' path leads directly to 'SET PI = presentation allowed'. The 'Permanent' path leads directly to 'SET PI = presentation restricted'. The 'Temporary' option leads through point 943 to a decision diamond 'Entered value?'. If 'Allowed', the flow goes to 'SET PI = presentation allowed'. If 'Restricted', it goes to 'SET PI = presentation restricted'. If 'None', it leads through point 943 to another decision diamond 'Default value?'. If 'Allowed', it goes to 'SET PI = presentation allowed'. If 'Restricted', it goes to 'SET PI = presentation restricted'. Both 'SET PI' blocks (which are also associated with point 943) lead to a junction point. From this junction, the flow proceeds to 'INFORM 2 req. ind.', which is associated with '947 FE3'.

+## FOREWORD
+
+The CCITT (the International Telegraph and Telephone Consultative Committee) is a permanent organ of the International Telecommunication Union (ITU). CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988).
+
+Recommendation Q.81, §§ 3 and 5 was prepared by Study Group XI and was approved under the Resolution No. 2 procedure on the 10th of September 1991.
+
+## --- CCITT NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency.
+
+## **STAGE 2 DESCRIPTION FOR NUMBER IDENTIFICATION SUPPLEMENTARY SERVICES**
+
+*(revised 1991)*
+
+## **3 Calling Line Identification Presentation (CLIP) and Calling Line Identification Restriction (CLIR)**
+
+### **3.1 Scope**
+
+This Recommendation defines the stage 2 of the integrated services digital network (ISDN) as provided by the telecommunications operators for the Calling Line Identification Presentation (CLIP) and Calling Line Identification Restriction (CLIR) supplementary services. Stage 2 identifies the functional capabilities and the information flows needed to support the service description. The stage 2 description also identifies user operations not directly associated with a call (see Recommendation I.130 [1]).
+
+This Recommendation is defined according to the methodology specified in Recommendation Q.65 [2].
+
+This Recommendation does not formally describe the relationship between these supplementary services and the basic call but, where possible, this information is included for guidance.
+
+In addition, this Recommendation does not specify the requirements where the service is provided to the user via a private ISDN. This Recommendation does not specify the requirements for the allocation of defined functional entities within a private ISDN; it does however define which functional entities may be allocated to a private ISDN.
+
+This Recommendation does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.
+
+The CLIP supplementary service provides the called party with the possibility to receive identification of the calling party.
+
+The CLIR supplementary service enables the calling party to prevent presentation of its ISDN number to the called party.
+
+The CLIP and CLIR supplementary services are applicable to all telecommunication services.
+
+This Recommendation is applicable to the stage 3 Recommendations for the ISDN CLIP and CLIR supplementary services, as defined in Recommendation I.130 [1].

+## ANNEX A (to § 3 of Recommendation Q.81)
+
+#### **Two calling-line-identities delivery option**
+
+#### A.1 *Scope*
+
+This annex specifies the additional procedures of the CLIP supplementary service that may be supported as a national network option.
+
+These national procedures shall have no impact and shall place no requirements whatsoever on the provision and operation of the CLIP supplementary service defined in this Recommendation by public ISDNs that do not support these additional procedures, nor on the interchangeability of terminals.
+
+#### A.2 *Additional procedures of FE4*
+
+If the procedures for delivery of the calling line identity as described in § 3.8 (SDL diagram for FE4) apply and the screening indicator is set to "user provided not screened", then the FE4 shall send the second calling line identity immediately following the first calling line identity. The second calling line identity shall be the default calling line identity of the access of the calling party. The second calling line identity shall be provided according to procedures described in this Recommendation.
+
+In all other cases, only the first calling line identity shall be sent.
+
+## 5 Connected Line Identification, presentation and restriction (COLP and COLR)
+
+### 5.1 Scope
+
+This Recommendation defines the stage 2 of the integrated services digital network (ISDN) as provided by public telecommunications operators for the Connected Line Identification Presentation (COLP) and Connected Line Identification Restriction (COLR) supplementary services. Stage 2 identifies the functional capabilities and the information flows needed to support the service description. The stage 2 description also identifies user operations not directly associated with a call (see Recommendation I.130 [1]).
+
+This Recommendation is defined according to the methodology specified in Recommendation Q.65 [2].
+
+This Recommendation does not formally describe the relation between these supplementary services and the basic call but, where possible, this information is included for guidance.
+
+In addition, this Recommendation does not specify the requirements where the service is provided to the user via a private ISDN. This Recommendation does not specify the requirements for the allocation of defined functional entities within a private ISDN; it does however define which functional entities may be allocated to a private ISDN.
+
+This Recommendation does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN.
+
+The COLP supplementary service provides the calling party with the possibility to receive identification of the connected party.
+
+The COLR supplementary service enables the connected party to prevent presentation of its ISDN number to the calling party.
+
+The COLP and COLR supplementary services are applicable to all telecommunication services.
+
+This Recommendation is applicable to the stage 3 standards for the ISDN COLP and COLR supplementary services. The term "stage 3" is defined in Recommendation I.130 [1].

The 'Temporary' path leads to a decision diamond 'Entered value?'. From this diamond, three paths emerge: 'Allowed' (left), 'Restricted' (right), and 'None' (down). The 'Allowed' and 'Restricted' paths lead to 'SET PI = presentation allowed' and 'SET PI = presentation restricted' blocks respectively. The 'None' path leads to another decision diamond 'Default value?'. From this diamond, two paths emerge: 'Allowed' (left) and 'Restricted' (right), both leading to the same 'SET PI' blocks as the 'Entered value?' decision. Both 'SET PI' blocks lead to a block labeled 'INFORM 2 req. ind.'. This block then leads to the exit. Various boxes are labeled with the number 943, and the 'INFORM 2' block is labeled with 947 FE3. A reference code T1126391-91 is present on the right side.

+Flowchart for COLP and COLR - FE4. It starts at node 12, leading to 'Subscriber restricted option'. From there, three branches: 'Not subscribed', 'Temporary (specified by user per call)', and 'Permanent (active for all calls)'. The 'Temporary' branch leads to 'Entered value?' decision. If 'Allowed', it goes to 'SET PI = presentation allowed'. If 'Restricted', it goes to 'SET PI = presentation restricted'. If 'None', it leads to 'Default value?' decision. If 'Allowed', it goes to 'SET PI = presentation allowed'. If 'Restricted', it goes to 'SET PI = presentation restricted'.

+
+#### 5.9.1 FEAs of FE1
+
+- 910: FE1 shall receive the service information from FE2;
+- 911: FE1 shall transfer the received information into a format that makes it usable for establishing a call;
+- 912: FE1 shall present the received information to the served user.
+
+#### 5.9.2 FEAs of FE2

+- 921: FE2 shall check if the connected line identity is provided. If the number is not available, then FE2 shall set the presentation indicator to “number not available”;
+- 922: FE2 shall check if presentation restrictions exist. If presentation restrictions exist, the number and sub-address information shall be erased, no number information shall be sent to the calling party and the received presentation indicator (PI) showing “presentation restricted” shall be sent to FE1 unless FE5 has the override category. If FE1 has such a category, then all the received information shall be sent to FE1;
+
+- 923: FE2 shall transfer the received information into a format that makes it usable by FE1 (e.g. adding prefixes);
+- 924: FE2 shall forward the information to FE1.
+
+#### 5.9.3 *FEAs of FE3*
+
+In the case of a national call, FE3 has null functionality.
+
+- 930: FE3 shall check if a partial number or no information is received. In this case no information is sent to FE2;
+- 931: FE3 shall check if the connected line identity may be passed between the networks;
+- 932: FE3 shall convert a national number to an international ISDN number if not already in this form. Number belonging to other numbering plans shall be passed transparently;
+- 933: if a number cannot be passed to FE2, FE3 shall erase the number and sub-address information and shall set the presentation indicator to “number not available”.
+- 934: FE3 shall forward the information to FE2.
+
+#### 5.9.4 *FEAs of FE4*
+
+- 940: FE4 shall check if the connected line identity is provided by FE5 and if not, shall include the default connected line identity with the presentation indicator set to “network provided”;
+- 941: FE4 shall verify connected line identity (unless a special arrangement for not screening the number exists);
+- 942: FE4 shall complete a partial number or a subscriber number to a national number. FE4 shall put the number into the format used in the current ISDN;
+- 943: FE4 shall set the presentation indicator;
+- 944: FE4 shall set the screening indicator;
+- 945: FE4 shall set the type of number (when a special arrangement exists, FE5 shall also set the type of number);
+- 946: FE4 shall set the numbering plan identification (when a special arrangement exists, FE5 shall also set the numbering plan identification);
+- 947: FE4 shall forward the information to FE3.
+
+#### 5.9.5 *FEAs of FE5*
+
+- 950: FE5 shall receive and shall forward destination users service requests to FE4;
+- 951: FE5 shall request the COLR supplementary service temporary mode (override of network stored value of presentation indicator);
+- 955: in the case of a special arrangement, FE5 shall screen the number to be provided;
+- 956: in the case of a special arrangement, FE5 shall complete the number to national or international format (for ISDN numbers);
+- 957: FE5 shall set the type of number;
+- 958: FE5 shall set the numbering plan identification.

+## **ITU-T RECOMMENDATION Q.824.6**
+
+## **STAGE 2 AND STAGE 3 DESCRIPTION FOR THE Q3 INTERFACE – CUSTOMER ADMINISTRATION: BROADBAND SWITCH MANAGEMENT**
+
+## **Source**
+
+ITU-T Recommendation Q.824.6 was prepared by ITU-T Study Group 4 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 26th of June 1998.
+
+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+**STAGE 2 AND STAGE 3 DESCRIPTION FOR THE Q3 INTERFACE –  
+CUSTOMER ADMINISTRATION: BROADBAND SWITCH MANAGEMENT**
+
+*(Geneva, 1998)*
+
+## **1 Introduction**
+
+### **1.1 Purpose and Scope**
+
+This Recommendation specifies the Q3 interface between an ATM switch and the Telecommunications Management Network (TMN). The interface specified is that between TMN Network Elements or Q-Adapters which interface to TMN Operations Systems (OSs) without mediation and between OSs and Mediation Devices, as defined in Recommendation M.3010 [5].
+
+The configuration by management of channels for signalling, including those for B-ISDN signalling, is within the scope of this Recommendation. The management of broadband customer administration and the configuration for call routing, including that for interworking with narrowband switches for both incoming and outgoing interfaces, is also within the scope of this Recommendation.
+
+An ATM switch may include ATM cross-connect functionality, but this is specified by reference to the ITU-T Recommendation on ATM network elements [4] and by importing the relevant classes of managed objects where appropriate.
+
+Existing protocols are used where possible, and the focus of the work is on defining the object model. The definition of the functionality of TMN Operations Systems is outside the scope of this Recommendation.
+
+Security management is also outside the scope of this Recommendation.

+### 3.3 Conventions
+
+Objects and their characteristics and associated ASN.1 defined here are given names with capitals used to indicate the start of the next word and acronyms are treated as if they were words.
+
+Throughout this Recommendation, all new attributes are named according to the following guidelines:
+
+- The name of an attribute ends in the string "Ptr" if and only if the attribute value is intended to identify a single object.
+- The name of an attribute ends in the string "PtrList" if and only if the attribute value is intended to identify one or more objects.
+- The name of an attribute is composed of the name of an object class followed by the string "Ptr" if and only if the attribute value is intended to identify a specific object class.
+- If an attribute is intended to identify different object classes, a descriptive name is given to that attribute and a description is provided in the attribute behaviour.
+- The name of an attribute ends in the string "Id" if and only if the attribute value is intended to identify the name of an object, in which case this attribute should be the first one listed, should use ASN.1 NameType and should not be used to convey other information.
+- The name of an attribute is composed of the name of an object class followed by the string "Id" if and only if the attribute value is intended to identify the name of the object class holding that attribute.
+
+## 4 General overview
+
+The following information model diagrams have been drawn for the purpose of clarifying the relations between the different object classes of the model.
+
+- 1) Entity Relationship Models showing the relations of the different managed objects;
+- 2) Inheritance Hierarchy showing how managed objects are derived from each other (i.e. the different paths of inherited characteristics of the different managed objects).
+
+These diagrams are only for clarification. The formal specification in terms of GDMO templates and ASN.1 type definitions are the relevant information for implementations.
+
+## 4.1 Entity Relationship Models
+
+The following conventions are used in the diagrams:
+
+![Conventions used in diagrams for Entity Relationship Models. The diagram shows various symbols: 'c' for containment, 'a' for association, 'i' for inheritance, '1:1' and '1:N' for cardinality, arrows for directionality, 'moc' for managed object class, a dashed box for uninstantiable object class, and a shaded box for managed object class outside the actual fragment.](2b3a967f6ce4f23649be995a353e39f8_img.jpg)
+
+The diagram illustrates the following conventions:
+
+- c**: is contained in
+- a**: is associated with
+- i**: 'is-a' relation (inheritance)
+- 1 : 1**: cardinality (represented by a double line with 'X' marks at both ends)
+- 1 : N**: cardinality (represented by a line with an 'X' mark at one end and an arrow at the other)
+- unidirectional**: relationship direction (represented by a line with an arrow)
+- bidirectional**: relationship direction (represented by a line with arrows at both ends)
+- moc**: managed object class (represented by a solid box)
+- moc** (dashed box): uninstantiable object class (superclass)
+- moc** (shaded box): managed object class outside the actual fragment

+Conventions used in diagrams for Entity Relationship Models. The diagram shows various symbols: 'c' for containment, 'a' for association, 'i' for inheritance, '1:1' and '1:N' for cardinality, arrows for directionality, 'moc' for managed object class, a dashed box for uninstantiable object class, and a shaded box for managed object class outside the actual fragment.
+
+**Figure 1/Q.824.6 – Conventions used in diagrams for Entity Relationship Models**
+
+Where the directionality of containment is not clear it can be identified by implications since the root class is unique.
+
+ATM switching network elements are represented by instances of the class atmSwitch and this contains, either directly or indirectly, all other managed objects which represent parts of the ATM switch.
+
+### 4.1.1 ATM generic modelling
+
+Modelling of ATM is restricted to bidirectional trails so that there is always a backwards channel for OAM purposes.
+
+The interfaces to the ATM switching network element consist of User-Network Interfaces (UNIs), which are labelled by instances of the class uni, and of Network-Network Interfaces (NNIs) which are labelled by instances of the class intraNNI if the interface is to the same network operator as the network element or by instances of the class interNNI if the interface is to a different network operator. The managed objects which label the interfaces are contained in the instance of managedElementR1 which represents the ATM switch and point to an instance of tcAdaptorTTPBidirectional class which represents the adaptation of the ATM layer to the underlying physical infrastructure.

+
+The diagram illustrates the Entity Relationship Model for ATM interfaces. At the top is a box labeled 'managedElementR1'. A line descends to a containment box 'c', which branches out to 'interNNI/intraNNI or UNI', 'tcAdaptorTTP Bidirectional', 'vpTTP Bidirectional', and 'vcTTP Bidirectional'. The 'interNNI' box has an association 'a' with 'tcAdaptorTTP Bidirectional'. The 'tcAdaptorTTP Bidirectional' box contains (via 'c') an 'atm Access Profile' and 'vpCTP Bidirectional'. The 'vpCTP Bidirectional' has an association 'a' with 'vpTTP Bidirectional'. The 'vpTTP Bidirectional' contains (via 'c') another 'atm Access Profile' and 'vcCTP Bidirectional'. Finally, 'vcCTP Bidirectional' has an association 'a' with 'vcTTP Bidirectional'. A reference number 'T0409540-98/d02' is at the bottom right.

+
+Instances of tcAdaptorTTPBidirectional are contained in the instance of managedElementR1. The adaptation to a physical infrastructure, represented by an instance of tcAdaptorTTPBidirectional, serves a number of virtual path trails which pass through the associated interface. The intermediate points on these trails which are served by the adaptation are represented by instances of vpCTPBidirectional class which are contained in the instance of tcAdaptorTTPBidirectional. The instance of tcAdaptorTTPBidirectional may also contain an instance of atmAccessProfile which characterizes the virtual paths.
+
+An instance of atmAccessProfile may also be contained in an instance of vpTTPBidirectional, which represents the end point of virtual path trail, to characterize the virtual channels served by the virtual path trail. The intermediate points of the virtual channel trails are represented by instances of vcCTPBidirectional which are contained in the instance of vpTTPBidirectional. The end points of the virtual channel trails are represented by instances of vcTTPBidirectional. Instances of vpTTPBidirectional and of vcTTPBidirectional are contained in the instance of managedElementR1.
+
+End points of virtual path trails (vpTTPBidirectional) must be directly associated with intermediate points (vpCTPBidirectional) using reciprocal upstream and downstream pointers. These pointers must also be used to associate the end points of virtual connections trails (vcTTPBidirectional) with their intermediate points (vcCTPBidirectional). A flexible cross-connection of two intermediate points at the same virtual level (either path or channel) is represented by an instance of atmCrossConnection. These instances are contained in an instance of atmFabric which represents the management of the cross-connection functionality and which is contained in the instance of managedElementR1. The upstream and downstream pointers may be used to associate a CTP object with a TTP object, or to associate CTP objects in a cross-connection, but not both simultaneously.

Loopback and alarm OAM flows are handled directly by the instances which represent the end points or intermediate points.

+## 7 Protocol stacks
+
+The protocol stacks specified in Recommendations Q.811, Q.812, G.773 and the SDH digital cross-connect part of Recommendation G.784 can be used as part of this Recommendation. The following Recommendations should be used to extend these stacks to include ATM:
+
+- Q.2811 Broadband Q3 and X interfaces – Lower Layer Protocols;
+- Q.2812 Broadband Q3 and X interfaces – Upper Layer Protocols.
+
+## ANNEX A
+
+### **Management requirements**
+
+This annex uses as a reference Recommendation I.751 [4] about the management of the ATM cross-connects, and describes or enhances management requirements for those aspects present only in the ATM switch.
+
+The complete set of management requirements for ATM switching network elements has to be composed from this and the above-mentioned Recommendation.
+
+ATM adaptation layer 5 is specified in Recommendation I.363.5 [2]
+
+The signalling ATM adaptation layer is split into the Service Specific Connection-Oriented Protocol (SSCOP) defined in Recommendation Q.2110 [7] and the Service Specific Coordination Function (SSCF) defined for the UNI in Recommendation Q.2130 [8] and for the NNI in Recommendation Q.2140 [9].
+
+DSS 2 user signalling is defined in Recommendation Q.2931 [11] and B-ISUP network signalling is defined in Recommendations Q.2761 to Q.2764 [10].
+
+#### **A.1 Configuration management functions**
+
+Configuration management provides functions to exercise control over, identify, collect data from and provide data to NEs.
+
+On one side, in an ATM cross-connect VP/VC connections are set up, modified and released via configuration management functions. On the other side, in an ATM switch, connections are set up, modified and released by signalling procedures, and configuration management is concerned mainly with managing control entities.
+
+##### **A.1.1 General NE configuration functions**
+
+This group of functions includes the set of procedures needed to bring the NE into service and to take care of hardware and software modifications and upgrades. It also includes the requirements for customer administration and call routing.
+
+##### **A.1.2 ATM transport layer configuration functions**
+
+###### **A.1.2.1 VPC/VCC configuration functions**
+
+The capability of setting a VP/VC connection in an unlocked administrative state (traffic flow is enabled), or in a locked state (traffic flow is suspended) must be provided.
+
+This capability will be used by system management to take corrective actions in response to performance degradation or fault of the virtual connection.
+
+### **A.1.3 ATM adaptation layer configuration functions**
+
+The various ATM adaptation layers generate requirements for configuration management and these requirements which are listed here. Each trail on the virtual channel layer supports a single ATM adaptation layer, which may either be configured or defined by call control. Unless otherwise stated, changes to the ATM adaptation layer may be requested, but such a request may be rejected if the change is not supported by the implementation. Likewise, unless otherwise stated, it shall always be possible to read the details of the actual configuration of the ATM adaptation layers.
+
+#### **A.1.3.1 Configuration management requirements for ATM adaptation layer 5**
+
+The following items may be read and changes may be requested:
+
+- the maximum number of octets in CPCS-PDU payload which is supported by ATM adaptation layer 5 both for transmit and for receive directions;
+- the form of data encapsulation used over the ATM adaptation layer 5 Service Specific Convergence Sublayer (SSCS).
+
+#### **A.1.3.2 Configuration management requirements for the signalling ATM adaptation layer**
+
+The type of Service Specific Convergence Sublayer (SSCS) used may be read and changes may be requested.
+
+It should be possible to configure timer values for the Signalling ATM Adaptation Layer (SAAL).
+
+### **A.1.4 Broadband signalling configuration functions**
+
+#### **A.1.4.1 Co-ordination of VPCI values**
+
+There is a requirement for management co-ordination between interconnected switches so that the switch which handles the signalling is aware of how the VPCI mappings differ from those of directly connected accesses when the access is connected indirectly via another switch with cross-connect functionality.
+
+### **A.2 Performance management functions**
+
+Performance management provides functions to evaluate and report upon the behaviour of telecommunications equipment and the effectiveness of the network element.
+
+Performance management functions will be based on Recommendation Q.822; the set of monitored parameters is detailed in the following subclauses.
+
+The identified functions for the ATM switches are concerned with performance and error measurements to report the general behaviour of the network element and can be useful to detect situations of degraded performance and identify possible causes of the abnormal situation.
+
+### **A.2.1 General NE performance functions**
+
+### **A.2.2 ATM transport layer performance functions**
+
+Three main sets of parameters need to be monitored; the first one is related to the OAM F4 and F5 flows mechanism, the second one deals with load and traffic related parameters, while the third one relies on system-dependent techniques.
+
+#### **A.2.2.1 F4 / F5 OAM flows related parameters**
+
+Performance monitoring is based on the use of OAM flows, both segment and end-to-end (see Recommendation I.610). At the ATM layer the F4 and F5 flows are considered.
+
+Each trail termination point must have the capability to generate the F4/F5 flows on the outgoing link and/or to process the incoming F4/F5 flows.
+
+These flows can be used to monitor the following parameters, at VP and VC layer, respectively:
+
+- bit error rate;
+- cell loss/insertion;
+- cell transfer delay;
+- cell delay variation.
+
+Suitable mechanisms are present in the flow, to support these functions, such as the Block Error Detection Code (BIP-X: see Recommendation I.610).
+
+When the measured values of these parameters exceed a preassigned threshold, an alarm is generated and sent to the TMN and to the control plane functions.
+
+#### **A.2.2.2 Load and traffic related parameters**
+
+The following parameters related to load and traffic need to be monitored; various methods can be used not included in the OAM flow mechanism:
+
+- internal overload/congestion;
+- external congestion;
+- blocking at virtual connection level.
+
+Functions responsible for the supervision of the overload and congestion state of the node (internal congestion) and of the network (external congestion) are examined below.
+
+Possible causes of overload can be faults inside the switching fabric, lack of internal capacity due to a poor system engineering that is unable to deal with traffic bursts, or malfunctioning of the UPC/NPC functions.
+
+Overload conditions can be indicated by overflow of the buffers located at the input and/or output of the switching fabric. In this case the automatic reaction to the condition is to discard cells, possibly in a selective way if a priority mechanism has been adopted.
+
+If the overload condition persists, the switch can enter into a congestion state. This status is also shown by a permanent buffer overflow condition.
+
+When a network elements enters in a congestion state, the system has to inform all the downstream nodes about its condition; a notification of this state is inserted in all the cells leaving the node through a particular code on the PTI field of the ATM cell header (I.361).
+
+The congestion indication is therefore propagated forward in the network.
+
+Monitoring of congested cells on a VP/VC basis can be used to prevent the congestion of the whole network.
+
+At virtual connection level, the switch can experience a connection blocking state when it is impossible to connect an allocatable VP/VC connection on an input interface with an equivalent allocatable VP/VC connection on the corresponding output interface. The connection control cannot accept the new VP/VC connection, although the interfaces have enough capacity available.
+
+Causes of this event can be internal blocking inside the switching fabric, due to implementation of the switching fabric itself with a blocking architecture, or use of resources management policies to guarantee the requested quality of service.
+
+### **A.2.2.3 Additional parameters**
+
+The following parameters need also to be monitored:
+
+- HEC error check;
+- Cell multiplexing error check;
+- UPC/NPC intervention.
+
+The HEC and the cell multiplexing error checking functions are performed at the lower layers of the B-ISDN protocol reference model (at physical layer and ATM layer, respectively). In the first case indications are provided about cells affected by multiple errors on the header, so that correction procedures cannot be applied; in the second case cells come in with an apparently correct cell header, but the internal VCI/VPI translation table does not contain any valid entry for that VCI/VPI. This means that a VCI/VPI multiplexing error has occurred.
+
+It is assumed that in both cases cells are discarded.
+
+The UPC and NPC functions mark or discard cells when they exceed the agreed service parameters. The number of tagged cells need to be counted on a VP and/or VC basis.
+
+### **A.2.3 ATM adaptation layer performance functions**
+
+Sets of parameters need to be monitored for the various ATM adaptation layers.
+
+### **A.2.3.1 Performance management requirements for ATM adaptation layer 5**
+
+Performance monitoring of ATM adaptation layer 5 is concerned with the use of the payload type field in the ATM cell header and the use of the last 8 octets of the CPCS-PDU [2]. In particular, the following should be monitored:
+
+- undelineated ATM cell sequences which are longer than the maximum number of cells in a CPCS-PDU;
+- inconsistencies between the number of ATM cells in a CPCS-PDU as indicated by the coding in the cells' payload type field and the length of the CPCS as indicated in the length field of the CPCS-PDU trailer;
+- the error rate as detected by the CRC field in the CPCS-PDU.
+
+In addition, the following performance statistics should be available:
+
+- number of received and transmitted PDUs;
+- PDUs discarded due to CRC errors;
+- PDUs discarded due to reassembly time out;
+- PDUs discarded due to overlarge size;
+- PDUs discarded due to protocol errors.
+
+## **A.3 Fault management functions**
+
+Fault management is a set of functions which enables the detection, isolation and correction of abnormal operation of the ATM switch.
+
+### **A.3.1 Alarm surveillance**
+
+#### **A.3.1.1 General NE alarm surveillance functions**
+
+No requirements identified.
+
+#### **A.3.1.2 ATM transport layer alarm surveillance functions**
+
+When a fault or a condition of severely degraded performance situation is detected, a connection termination point must be able to send a VP-AIS alarm on the OAM F4/F5 flow, and to send an alarm to the TMN and to the control plane functions.
+
+#### **A.3.1.3 ATM adaptation layer alarm surveillance functions**
+
+Detected problems in the ATM adaptation layers will generate various alarms.
+
+#### **A.3.1.3.1 Alarm surveillance management requirements for ATM adaptation layer 5**
+
+Alarms are generated under the following conditions:
+
+- when the payload type field in the ATM cell header fails to indicate the last ATM cell of a CPCS-PDU for more than the maximum number of cells in a CPCS-PDU;
+- when the number of ATM cells in a CPCS-PDU is not consistent with the length of the CPCS as indicated in the length field of the CPCS-PDU trailer;
+- when the error rate as detected by the CRC field in the CPCS-PDU becomes too high.
+
+### **A.3.2 Test and fault localisation**
+
+#### **A.3.2.1 General NE test and fault localisation functions**
+
+No requirements identified.
+
+#### **A.3.2.2 ATM transport layer test and fault localisation functions**
+
+The mechanism of continuity check, performed using OAM F4/F5 flows, is used for testing the integrity of the translation and routing tables of the NE. When a connection termination point does not transmit user cells and there is no failure indication through the VP-AIS and VP-FERF signals, then it must be able to send a continuity check signal. If the receiving termination point receives no OAM cells, it will generate a VP-FERF signal. This mechanism is useful for localisation of the termination points that has experienced a failure.
+
+#### **A.3.2.3 ATM adaptation layer test and fault localisation functions**
+
+When a fault is suspected in the ATM adaptation layers, or an alarm has been generated, it may be necessary to perform activities to check the correct operation of the ATM adaptation layers and to identify the origin of a confirmed ATM adaptation layer fault.
+
+##### **A.3.2.3.1 Testing and fault localisation requirements for ATM adaptation layer 5**
+
+Non-intrusive testing of ATM adaptation layer 5 shall be carried out by generating and detecting patterns on the CPCS-UU octet of the CPCS-PDU trailer and/or on the padding octets. Intrusive testing of ATM adaptation layer 5 shall be carried out by generating and detecting patterns on the CPCS-PDU payload. These patterns may either be looped back to their source or sent in a single direction.
+
+### **A.3.3 Fault correction**
+
+#### **A.3.3.1 General NE fault correction functions**
+
+No requirements identified.
+
+### **A.3.3.2 ATM transport layer fault correction functions**
+
+When a failure in a VP/VC connection occurs, it is possible to perform fault correction by protection switching.
+
+The mechanism of protection switching is based on the use of a spare VP/VC connection, shared among a group of active virtual connections; it is directed by Layer Management.
+
+## **A.4 Modelling specific requirements**
+
+Recommendation Q.2764 describes a parameter Transit Network Selection for the setup messages. This parameter may be "included in the setup message from the calling party or provided on a subscription basis". This information "is used for routing the call/connection, e.g. to a specific B-ISDN".
+
+To support this parameter, it should be possible to assign a preferred carrier (transit network) value either to the whole customer or to an individual directory number.
+
+Recommendation Q.2764 describes a parameter Calling Party Category for the setup messages.
+
+To support this parameter, it should be possible to assign a category value either to the whole customer or to an individual directory number.
+
+The Call Routing Management allows to mark a NNI with an origination mark, to support the origination dependent routing of incoming calls. Origination dependent routing should be possible for calls coming from an UNI too.
+
+It should be possible to mark either the whole customer or an individual directory number with an origination mark, which can be used e.g. for the origination dependent routing.

+# **ITU-T Recommendation Q.834.1**
+
+# **ATM-PON requirements and managed entities for the network and network element views**
+
+## **Summary**
+
+This Recommendation defines the managed entities that are required to support the requirements for the management of a Passive Optical Network (ATM-PON). These definitions are to be used to develop a protocol-neutral information model. A network element view combined with a network view of an ATM-PON is modelled according to a protocol-neutral information modelling concept. The concept provides a protocol-neutral MIB and thus permits developers to derive an implementation-specific MIB from any management protocol. The information model described herein is used on an interface between a Network Management Layer and an Element Management Layer.
+
+### **Source**
+
+ITU-T Recommendation Q.834.1 was approved on 13 June 2004 by ITU-T Study Group 4 (2001-2004) under the ITU-T Recommendation A.8 procedure.
+
+### **Keywords**
+
+APON, BPON.
+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+### NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# ITU-T Recommendation Q.834.1
+
+# ATM-PON requirements and managed entities for the network and network element views
+
+## 1 Scope
+
+This Recommendation specifies an information of ATM-PON system at a Q interface at a reference point beyond an element management layer (ITU-T Rec. M.3013). This Q interface is defined as the network and network element views.
+
+This Recommendation provides network as well as network element view managed entities to support a protocol-neutral information model for ATM-PON. As a consequence, the managed entities and their properties will be used to develop a protocol-neutral information model. The model may then be used to develop specific MIBs, which are appropriate for the management protocols. These managed entities are specific to the ATM-PON system. Therefore, the suffix "F" is added to their names in order to distinguish them from generic managed entities.

+
+### 6.1 Operations architecture
+
+This Recommendation addresses the management functions of FSAN network elements across the Q interface.
+
+The operation systems manage FSAN network elements and their interface ports through the Q interface by means of managing OLT. FSAN network elements include OLT, ODN, ONU, NT and ONT (ITU-T Rec. G.983.1) shown in Figure 1. The ODN offers one or more optical paths between one OLT and one or more ONU/ONTs. ONU and NT are connected by ADSL or VDSL. OLT has a BICI/BISSI port towards the core network, and ONT/NT has one or more UNI port(s) for the customers. The OLT manages ONU, NT and ONT (ITU-T Rec. G.983.2).
+
+The FSAN Element Management System (FSAN EMS) consists of E-OSF and includes a little N-OSF and S-OSF (ITU-T Recs M.3010 and M.3013) and manages all the FSAN network elements shown in Figure 1. The Q interface specifies a network element view combined with a network view. This interface is called IF1 in the FSAN operations requirements in Appendix I.
+
+![Figure 1/Q.834.1 – FSAN network elements and target interface of operations architecture. The diagram shows a three-layer architecture. The top layer is the 'Network management layer' containing the 'FSAN network management system'. The middle layer is the 'Element management layer' containing the 'FSAN element management system (E-OSF, N-OSF and S-OSF)'. These two layers are connected by a thick line labeled 'Q'. The bottom layer is the 'Network element layer', which contains a dashed box labeled 'FSAN network elements'. Inside this box, the components are connected in a sequence: BICI/BISSI (represented by a vertical bar) connects to OLT (represented by a rectangle), which connects to ODN (represented by an oval), which then connects to a stack of ONU and NT (represented by rectangles), and finally to a stack of ONT (represented by rectangles). The ONT stack connects to UNI (represented by a vertical bar). A line from the 'FSAN element management system' box points to the OLT box. Another line from the 'FSAN element management system' box points to the ODN oval. A third line from the 'FSAN element management system' box points to the ONT stack. The label 'Q.834.1_F1' is at the bottom right.](a83ba9e3e2c1e21dd69953a7b09e45b4_img.jpg)

+### 6.2 NE view combined with NW view (Combined view)
+
+This Recommendation adopts a combined view defined as the network element (NE) view combined with the network (NW) view in order to treat both FSAN network element and FSAN subnetwork.
+
+## **7 Requirements**
+
+The general requirements for the ATM-PON operation system are described in FSAN operations requirements in Appendix I. This Recommendation uses some of them and derives fault processing from fault management requirements and performance monitoring from performance management requirements.
+
+### **7.1 Related requirements**
+
+The number and letter written after the requirements refer to an associated item in Appendix I, FSAN operations requirements.
+
+#### **7.1.1 Configuration management**
+
+For equipment installation, automatic detection shall include the following sequence of activities: installation, power-up self test, equipment authentication, read inventory information, report installation to the FSAN EMS, and download of configuration information. Inventory information shall be read and sent to the FSAN EMS, where possible, regardless of whether the equipment is of the correct type. (38 M)
+
+The FSAN element management system shall be able to create the logical representations of the resources required to manage the network and services. All necessary network and service parameters shall be supplied in the appropriate request. (77 M)
+
+It shall be possible to create the logical resources in the FSAN element management system without the need for equipment to be physically present in the network. (79 M)
+
+The FSAN element management system shall automatically allocate the required resources if they are not identified in the provision request. (82 M)
+
+If all spare and installed resources are in use, the FSAN element management system shall use the next available spare and not the installed resources. (83 M)
+
+If there are no spare resources awaiting installation, then the FSAN element management system shall propose a list of equipment that need to be installed to allow the request to be fulfilled. The equipment list shall indicate:
+
+- the type of equipment to be installed;
+- the location where it is to be installed (rack/shelf/slot, OLT or ONU, etc.);
+- the software and hardware versions that are compatible with the existing version of installed hardware. (84 M)
+
+Each equipment list shall be stored in the FSAN element management system until an event is received from the NE to indicate that the network equipment has been physically installed and has been correctly authenticated. (85 M)
+
+It shall be possible to pre-configure equipment prior to its installation by providing the required data when the logical representation is created. (86 M)
+
+It shall be possible to modify service parameters (such as bit rate, service type, error checking as applicable) for individual UNI(s) or virtual paths (VPs). (87 M)
+
+The NMS shall be able to create logical resources and paths for end-to-end network and service provision. All necessary parameters shall be supplied in the appropriate request. (121 M)
+
+It shall be possible to create the logical resources in the NMS without the need for the FSAN element management system to be present. (123 M)
+
+The NMS user shall receive an indication on the success or failure of all operations. (127 M)
+
+#### 7.1.2 Fault management
+
+Fault management refers to the broad set of functions associated with the detection, isolation, reporting and correction of abnormal operational conditions in the network. In this context, fault management consists of the following:
+
+- alarm surveillance (detecting/receiving events);
+- event processing (correlation and filtering);
+- fault localization;
+- event logging;
+- testing. (24 M)
+
+Network equipment is required to automatically perform a self test (where applicable) when connected to the network. Completion of the self test should leave the network equipment in a known state. An event shall be sent to the FSAN EMS to indicate failure of the self test. (50 M)
+
+It shall be possible to perform service-specific tests associated with the transport medium between the ONU and NT, where the ONU and NT are separate. The test functions, where possible, should also be able to determine if the customer's equipment is present or absent. Any faults detected during testing shall be reported to the FSAN EMS. (55 M)
+
+It shall be possible to accurately distinguish between faults on the ODN and faults on the ONU possibly through the use of internal event correlation and test functions. (57 M)
+
+Detection of a fault, through network surveillance or network testing, which is affecting service shall cause the related equipment to be placed in an unavailable state for provisioning purposes. (100 M)
+
+It shall be possible to block and unblock resources that provide service to allow equipment to be maintained. Whilst a resource is blocked for maintenance purposes, it shall not be possible to use the service supported by that resource. The event report shall use the format described in ITU-T Rec. X.733. (101 M)
+
+The FSAN EMS shall be capable of reporting the following categories of faults to the NMS:
+
+- faults on the network equipment;
+- faults on interfaces;
+- environmental conditions within the network element where applicable. (102 M)
+
+Fault reports shall accurately indicate the cause, severity, time and location of conditions detected by the network down to specific replaceable equipment. (103 M)
+
+It shall be possible to invoke self tests on specific network equipment from the FSAN EMS. (106 M)
+
+It shall be possible to verify the correct configuration of a service by requesting a connection test from the FSAN EMS to the NE. (107 O)
+
+Where there is an occurrence of a large number of faults, the FSAN EMS shall analyse and correlate the faults within its domain to determine the underlying cause of the problem. This should result in the escalation of one fault report with an appropriate repair action to a user or NMS. (108 M)
+
+It shall be possible to set and modify service-specific failure thresholds. A fault shall be reported to the specified users or NMS when a threshold is exceeded. (109 M)
+
+All fault reports shall be logged. (111 M)
+
+The FSAN EMS shall accept and act on requests to permit/inhibit fault reports from the NMS. (112 M)
+
+It shall be possible to apply test loops to the NE manually on a demand basis during fault diagnosis or automatically as part of background test routines to aid proactive fault location. It shall be possible to activate/deactivate a bit error rate test source in the NE to check for errors on the path between the loops. (113 M)
+
+It shall be possible for an NM-OSF to permit/inhibit fault reports to/from an FSAN EMS. (133 M)
+
+#### **7.1.3 Performance management**
+
+Once installed, the network equipment shall be monitored to provide information on network performance and service performance. Measurements shall be based on monitoring network or service parameters. An event shall be sent to the FSAN EMS when the monitoring function detects that a threshold for a parameter has been exceeded. Monitoring shall not affect customer traffic. (62 M)
+
+It shall be possible to activate and de-activate scheduled reporting of current and historical performance data of the network from the FSAN EMS. The parameters used for monitoring shall be configured with network defaults and shall be modifiable where applicable. It shall not be possible to modify any parameters once all monitoring criteria are set and monitoring has been activated without first de-activating. (65 M)
+
+When a monitoring function is activated, it shall be possible to specify a time period over which performance information is to be recorded. The time period shall be configurable. (66 M)
+
+The NE shall suppress all monitoring intervals that have zero counts within any scheduled report that is sent to the FSAN EMS. (68 M)
+
+Performance monitoring shall involve gathering current and historical statistical data relating to 15-minute intervals over a 24-hour period for the purpose of monitoring and correcting the behaviour and effectiveness of the network. This information should also assist network analysis, network planning, capacity management and billing processes. (69 O)
+
+It shall be possible to activate and de-activate the performance monitoring functions from the FSAN EMS. When a monitoring function is activated, it shall be possible to specify a time period over which performance information is to be recorded. The time period shall be configurable. (115 M)
+
+Certain performance monitoring data shall be collected automatically to support the generation of Quality of Service (QoS) information. The management system shall provide QoS information for each of the ATM Constant Bit Rate (CBR), Variable Bit Rate (VBR) and Available Bit Rate (ABR) class of service supported by the network. This information shall include cells discarded, CLP=0 cells discarded, cells successfully passed and CLP=0 cells successfully passed. (116 M)
+
+The EM-OSF shall provide performance data on demand via the user interface or shall generate performance reports periodically as reports according to a pre-established schedule. (118 M)
+
+#### **7.1.4 NW view management**
+
+The FSAN element management system shall be able to create the logical representations of the resources required to manage the network and services. All necessary network and service parameters shall be supplied in the appropriate request. (77 M)
+
+It shall be possible to create the logical resources in the FSAN element management system without the need for equipment to be physically present in the network. (79 M)
+
+The FSAN element management system shall automatically allocate the required resources if they are not identified in the provision request. (82 M)
+
+If all spare and installed resources are in use, the FSAN element management system shall use the next available spare and not the installed resources. (83 M)
+
+If there are no spare resources awaiting installation, then the FSAN element management system shall propose a list of the equipment that needs to be installed to allow the request to be fulfilled. The equipment list shall indicate:
+
+- the type of equipment to be installed;
+- the location where it is to be installed (rack/shelf/slot, OLT or ONU, etc.);
+- the software and hardware versions which are compatible with the existing version of installed hardware. (84 M)
+
+Each equipment list shall be stored in the FSAN element management system until an event is received from the NE to indicate that the network equipment has been physically installed and has been correctly authenticated. (85 M)
+
+It shall be possible to pre-configure equipment prior to its installation by providing the required data when the logical representation is created. (86 M)
+
+It shall be possible to modify service parameters (such as bit rate, service type, error checking as applicable) for individual UNI(s) or Virtual Paths (VPs) when the relevant resources are out of active use. (87 M)
+
+The NMS shall be able to create logical resources and paths for end-to-end network and service provision. All necessary parameters shall be supplied in the appropriate request. (121 M)
+
+It shall be possible to create the logical resources in the NMS without the need for the FSAN element management system to be present. (123 M)
+
+The NMS shall receive an indication on the success or failure of all operations from FSAN element management system. (127 M)
+
+#### **7.1.5 Others**
+
+It shall be possible to archive logs periodically using back-up mechanisms. Archiving shall not affect current logs. (34 M)
+
+The Data Communications Network (DCN) that conveys the management information between the operations functions is a key component of the management architecture. (137 I)
+
+### **7.2 Fault processing**
+
+Figure 2 shows the basic sequence of operations that are executed during fault processing.
+
+- Anomaly processing deals with the detection of faults or abnormal conditions and generating the corresponding fault notification.
+- Filtering is used to filter a fault notification depending on the type and cause of the failure.
+- Persistency processing allows the network element to hold a notification for a certain time or to forward a notification if a configurable number of fault occurrences or abnormal conditions have taken place in a specified time window. Thus, transient and toggling defects can be filtered. Therefore, timers are required which can be modified at installation time only. Persistency processing uses a persistency profile.
+- Assign severity is used to assign a predefined severity to an alarm. Severity assignment is to be supported for each alarm. The assign severity profile includes the classification of alarms.
+- Correlation of alarm is used to allow the FSAN EMS to report only the root cause of the event.
+
+- Notification generates the alarm format that will be logged and/or forwarded to other network management system functions.

+### 7.3 Performance monitoring
+
+Performance monitoring is described based on the network layer structure shown in Annex B.
+
+The OLT will always stay in a 1:N relationship to ONU or ONT, and the ONU will always have a 1:1 relationship to the NT. The ONT/NT side ends with either a ATM 25 Mbit/s or an IP interface or a Leased Line interface. The different possible layers of performance monitoring are shown in Figures 3, 4 and 5.

+**Figure 5/Q.834.1 – Performance monitoring on AAL** Performance monitoring is a function to produce user- or service-dependant information to indicate the state of connections for maintenance. For performance monitoring, the source of the connection/link and the sink of the connection/link will be considered. Table 1 describes the required attributes for collection of information and the related managed entities (always bidirectional). A suffix "FSAN" is omitted from each entity. ITU-T Recommendation numbers for the related managed objects are written in the table as references. Traffic management or monitoring will always be executed at one point in the network.

+### 8 Managed entities
+
+This clause describes the managed entities that are visible across the Q interface. These managed entities are abstract representations of resources and services in a full service access network. Managed entities are defined in a protocol-neutral fashion. Further work will be required to make the MIB definitions protocol-specific (e.g., CMIP- or CORBA-compliant). Some MIB definitions defined herein are based on the models defined by the ATM Forum [20]. New specific classes are so indicated.
+
+This Recommendation uses a combined view defined in 6.2. Some managed entities for the network view and those for the network element view are pointed to each other in the combined view. Figures 6-1 and 6-2 illustrate combined view managed entities relevant to APON layer.

+**Lost0UserInformationCells:** This attribute measures background cell loss. It cannot distinguish between cells lost because of header bit errors, ATM-level header errors, cell policing, or buffer overflows. It records only loss of genuine user information of high priority.
+
+**MisinsertedUserInformationCells:** This attribute is used to measure small occurrences of when a cell is mis-routed to an active VP/VC that is being monitored.
+
+**Transmitted0+1UserInformationCells:** A count of all the user cells that are originated at a monitored connection by the transmitting end point (i.e., backward reporting is assumed).
+
+**Transmitted0UserInformation Cells:** A count of all the user cells of high priority that are originated at a monitored connection by the transmitting end point (i.e., backward reporting is assumed).
+
+**ImpairedBlock:** The severely errored cell block counter will be incremented whenever one of the following events takes place: the number of misinserted user cells exceeds  $M_{\text{misinserted}}$ , the number of bipolar violations exceeds  $M_{\text{errored}}$ , or the number of lost user cells exceeds  $M_{\text{lost}}$ .

+## Appendix I
+
+### FSAN operations requirements
+
+#### I.1 Introduction
+
+- 1 I Since early 1995 a number of operators and suppliers have collaborated on developing solutions and designs for delivering a low-cost full-services access network (FSAN). The operator members of this collaboration believe that agreement on a common set of requirements on as many aspects as possible will lead to a cost-effective solution. It was also decided that involving suppliers at an early stage of the discussions would enable them to deliver the required solutions. A number of working groups were set up to facilitate this, each covering a specific area of the FSAN [I-1].
+- 2 I This appendix describes the set of common requirements which have been developed by the OAM group members (both operators and suppliers). The requirements cover the following aspects of OAM:
+- a) High-level business processes;
+  - b) Network Management Architecture;
+  - c) Operational requirements;
+  - d) OAM of the transmission medium.
+- 3 I Requirements from the other FSAN working groups have also been used as an input to this work [I-2].
+- 4 I NOTE – All statements in this appendix are numbered "n x" to aid traceability where "n" is an integer number starting from 1 and "x" indicates the type of statement. The statement can be an (I)nformation statement, a (M)andatory requirement or an (O)ptional requirement.
+
+#### I.2 Processes
+
+- 5 I Operators are increasingly using process engineering methods to describe the flow of fundamental business activities to assist them in defining the required operational system functionality. Once these processes are understood it is possible to determine which activities can be automated to provide improvements in operations.
+- 6 I A process can be viewed as a series of tasks that describe the operations functions and the relationship between the functions. Processes also identify the instances of data that are manipulated by the operations functions.
+- 7 I Every operator defines processes suitable for his organization and infrastructure by grouping tasks in different ways to form unique business processes. This makes it difficult to define a set of common detailed processes that are applicable to every operator. For this reason, this appendix describes a small set of high-level processes which cover most of the tasks for specific operations as an aid to understanding the source of the management requirements. Although the names of the processes may need to be translated to equivalent names within each operator's organization, they are considered to be generally applicable to each operator. Process work by the Network Management Forum (NMF) [I-3] may also help to understand the set of activities that every operator has to address.
+- 8 I Some of the key activities involve planning and engineering, service and network provisioning, network repair, network testing and accounting.
+
+9 I The following clauses describe high-level examples of some of the key processes which can be used to provision and maintain the FSAN and to manage services. These, together with operators' experience, have been used as a baseline for developing the management requirements described in this appendix.
+
+### **1.2.1 Planning and engineering**
+
+10 I This process ensures that sufficient network resources are available to meet overall customers needs (see Figure I.1). The process performs trend analysis of customer network usage and generates demand forecasts on network resources. The process will be used to determine access network capacity such as PON bandwidth, OLT/ONU/ONT line cards, VP/VC switch and cross-connect requirements. The process requires network usage, planning and engineering data for analysis.

+
+## **I.2.2 Service provision**
+
+- 11 I This process covers the set of tasks required to deliver service to customers across the FSAN. The process is illustrated in Figure I.2. This process begins with customer interaction to record customer data and service data to meet the customer's request. Other activities of this process are responsible for tracking the progress of the request and for updating (interacting with other functions) at particular times. For example, it may be necessary to verify the customer's credit history prior to progressing an order. On completion of the order, accounting data is updated to ensure that the customer can be effectively billed for the service. Other functions covered include network planning, work force scheduling and the provisioning of network equipment (OLTs, ONUs, ONTs, NTs, Service cards and so on).

+### **I.2.3 Network repair**
+
+- 12 I Network repair involves the set of tasks required to determine the cause and location of faults in the FSN and the tasks needed to restore service at the contracted service level. Network repair can be proactive or reactive. Proactive repair can be initiated as a result of network self-diagnostics in terms of hardware, software or traffic conditions. A network operator will normally initiate reactive repair on receipt of a report from a customer indicating a degradation or fault in the service being delivered over the network.
+- 13 I Figure I.3 shows the tasks for reactive repair of the network. Particular functions involved include trouble administration, surveillance, performance monitoring and testing. Proactive repair will contain similar steps except that the process will be driven by event reports from the network rather than from a report by the customer.

+
+- 14 I This clause provides a definition of the management terms used in this appendix, the FSAN target management architecture, and the management interfaces.
+- 15 I A definition of the terms (see Table I.1) is necessary to ensure a common understanding. Where necessary, the definitions are based on those used in ITU-T Recs M.3010 [I-4], M.3013 [I-14], G.902 [I-5] and G.982 [I-6].

+Q.834.1\_F14
+
+NOTE – The F interface as defined in ITU-T Rec. M.3010 is not shown in this figure but is implicit where there is an OSF.
+
+**Figure I.4/Q.834.1 – Target network management architecture**
+
+- 17 I An OSF should not be interpreted as a physical systems implementation. One or more OSFs may reside on one or more physical platforms.
+- 18 M Each interface is shown with a lower case reference point (e.g., if1) and an uppercase implementation option of that interface (e.g., IF:Q3/CORBA) if it physically exists between two systems. This requirement specifically refers to reference points if1, if3, if4 and if6 in Figure I.4.
+- 19 M Where a Q3 implementation is adopted, this shall be based on the Telecommunications Management Network (TMN) interface [I-7] using the Common Management Interface Protocol (CMIP) [I-8] and [I-9]. With this approach, a high-layer management function will contain a "manager" function and a lower-layer management function will contain an "agent" function. Management operations are communicated between the manager and agent functions using CMIP. It is not necessary to implement a Q3 interface if the management functions reside on the same physical system.
+
+- 20 I The purpose of showing these interfaces is to determine the management information flows and data which will pass between the management functions. Information flows will be realized through management services between operations functions. Table I.2 gives a brief description of the possible management services provided at each reference point. The management flows are currently under study.

+## **I.4 Management requirements**
+
+### **I.4.1 Scope**
+
+- 21 I This clause defines the management requirements for Network Element and Element Management layers, as shown in the logical architecture. The requirements have been further subdivided under the Configuration, Fault, Performance, Accounting and Security management functions within each layer. In addition, some requirements have been included for the Network Management and Service Management Layer.
+
+### **I.4.2 Common management requirements**
+
+- 22 I This clause defines requirements that are considered to be common for all layers in the FSAN architecture. All management functions and interfaces shall be based on existing standard information models and interfaces where possible.
+- 23 M All management functions are required to support the range of services defined in [I-10].
+
+#### **I.4.2.1 Fault management**
+
+- 24 M FSAN fault management refers to the broad set of functions associated with the detection, isolation, reporting and correction of abnormal operational conditions in the FSAN network. In this context, fault management consists of the following:
+- alarm surveillance (detecting/receiving events);
+  - event processing (correlation and filtering);
+  - fault localization;
+  - event logging;
+  - testing.
+
+#### **I.4.2.2 Security**
+
+- 25 M Access to management functions and data at any layer, either by users or external systems, shall require authentication and access control.
+- 26 M Users or external systems shall be authenticated through a challenge-response mechanism. This mechanism involves authentication through the use of identification and passwords. The mechanism may include use of devices such as smart cards for user identification.
+- 27 M It shall be possible to configure the identification, the minimum length of the password, the expiry time of the password, the maximum allowed attempts "m" to enter the password and the retry expiry timeout for each individual user or external system.
+- 28 M A user failing "m" attempts to enter the correct password shall be denied further attempts to gain access until expiry of the retry time-out. In this case, a security violation event shall be logged and a message shall be displayed, if appropriate, to indicate that access has been denied.
+- 29 M Passwords shall not be echoed when entered and shall be encrypted if transmitted over any communications link.
+- 30 M It shall be possible to configure the management functions and data available to a user or external system. The access parameters shall be based on read/write/modify/execute/delete privileges, geographic location, service type, time period over which access is allowed, functions available, data available and user profile and/or system name.
+- 31 M Illegal attempts to access functions and or data shall be reported as a security violation. All accesses shall be logged.
+- 32 M If a security violation is detected, the security function shall isolate the user or external system to prevent any further access attempts.
+
+### **I.4.2.3 Logs**
+
+- 33 O All OSF log(s) shall operate in a first-in first-out basis in case of overflow. It shall be possible to configure a log to send an event, to a higher-layer management system, when a log full threshold has been exceeded or an overflow occurs.
+- 34 M It shall be possible to archive logs periodically using back-up mechanisms. Archiving shall not affect current logs.
+- 35 M It shall be possible to read all OSF logs (current or archived) from the user interface.
+
+### **I.4.3 Network element layer requirements**
+
+#### **I.4.3.1 Configuration management**
+
+- 36 M All network equipment shall be modular in design so that it is easy to install, remove, replace or upgrade without affecting existing services to other customers.
+- 37 M The NE shall automatically detect the installation and removal of network equipment.
+- 38 M For equipment installation, automatic detection shall include the following sequence of activities: installation, power-up self test, equipment authentication, read inventory information, report installation to the EM-OSF, and download of configuration information. Inventory information shall be read and sent to the EM-OSF, where possible, regardless of whether the equipment is of the correct type.
+- 39 M Download of configuration information shall be performed automatically following successful installation or on request from the EM-OSF. The configuration information shall include service-specific software where appropriate. Configuration of the equipment shall not be allowed if the associated logical resources do not exist in the EM database.
+- 40 M For equipment removal, the NE is only required to report the event to the EM-OSF.
+- 41 M An event report shall be sent to the EM-OSF to indicate the success or failure of the equipment installation or removal. This event shall contain the following information:
+  - a) type of network equipment (known, unknown or incompatible);
+  - b) an indication of whether the installation/removal succeeded or failed; and
+  - c) inventory of the network equipment (e.g., equipment id, hardware and software version) if the equipment is known or incompatible. No inventory information if the equipment is unknown.
+- 42 M Any change of equipment state and relationship information shall be communicated to the EM-OSF by event reports. This information shall accurately reflect the status of the network equipment that exists or has been built in the NE database.
+- 43 M The NE shall store all operational and service-related parameters (e.g., slot assignments, power levels, cross-connections, etc.) in the NE database.
+
+#### **I.4.3.2 Fault management**
+
+- 44 M The NE shall continue to function if it loses management communications with the EM-OSF.
+- 45 O The NE should perform a connection test from the SNI port on the OLT to the UNI port on the NT when the NT/ONT is installed to ensure that the path between the SNI and UNI is correctly configured.
+
+- 46 M There shall be simple visual indications (e.g., light-emitting diode) to confirm faults on the network equipment and to aid local maintenance procedures, where appropriate. All visual indications shall be consistent with the state of the network equipment. Where appropriate, the following shall be indicated:
+- faults on the equipment;
+  - status of external interface(s), if present (e.g., signal present/not present);
+  - equipment synchronizing/synchronized;
+  - whether equipment is main or standby.
+- 47 M It shall be possible to identify (via an LED) which is a main (currently operating) resource and which is the standby for those resources which are protected. A protection switching function shall be provided to switch to the standby resource if there is a fault on the main resource. On switch-over, the standby resource shall become the main resource and the main resource shall become the standby resource. The protection switch event shall be reported to the EM-OSF.
+- 48 M Events indicating faults should be reported as soon as a fault has been detected following any persistence checks and correlation performed by the NE. A single event should be raised following correlation.
+- 49 M Event reports shall not be raised against equipment that has been created in the NE database but has not yet been installed.
+- 50 M Network equipment is required to automatically perform a self-test (where applicable) when connected to the network. Completion of the self-test should leave the network equipment in a known state. An event shall be sent to the EM-OSF to indicate failure of the self-test.
+- 51 M The network equipment shall not require the manual use of specialized fault-finding techniques or tools to diagnose faults in the OLT, ODN, ONU or NT.
+- 52 M The NE shall support network or customer facing loops to determine the integrity of the access network or parts of the access network. Logical loops shall be provided at the ATM layer for maintenance and performance management using OAM cells. It shall be possible for the EM-OSF to request application of logical loops on the FSAN NE.
+- 53 O Physical loops shall be provided on the interfaces at the OLT and ONU/ONT. Physical loops shall be applied on request from the EM-OSF.
+- 54 M A bit error rate test source shall be provided in the OLT. Activation and de-activation of the test source shall be carried out on request from the EM-OSF.
+- 55 M It shall be possible to perform service-specific tests associated with the transport medium between the ONU and NT, where the ONU and NT are separate. The test functions, where possible, should also be able to determine if the customer's equipment is present or absent. Any faults detected during testing shall be reported to the EM-OSF.
+- 56 M Detection of failures in the received transport signal at the OLT or ONU/ONT shall cause the NE to report the fault to the EM-OSF. If the failure is detected at the OLT, an immediate switch shall be performed to a standby ODN interface if available. A failure on the received signal (downstream) at the ONU/ONT shall not result in the corruption of data on the ODN in the upstream signal to the OLT. In this case, the ONU shall attempt to indicate the failure to the OLT.
+- 57 M It shall be possible to accurately distinguish between faults on the ODN and faults on the ONU possibly through the use of internal event correlation and test functions.
+- 58 M Any outstanding new event shall be made available to the EM-OSF following restoration of communications with the NE.
+
+- 59 M A local craft terminal interface shall only be used for equipment installation.
+- 60 O Any test function which is employed shall accurately report the location of a fault on the ODN.
+- 61 O The NE shall automatically re-configure its internal resources (software) to rectify a fault where possible.
+
+#### **I.4.3.3 Performance management**
+
+- 62 M Once installed, the network equipment shall be monitored to provide information on Network Performance and Service Performance. Measurements shall be based on monitoring network or service parameters. An event shall be sent to the EM-OSF when the monitoring function detects that a threshold for a parameter has been exceeded. Monitoring shall not affect customer traffic.
+- 63 M Performance data shall be generated based on performance parameters that have been configured.
+- 64 M Error-rate performance measurements shall be provided at specific points in the NE.
+- 65 M It shall be possible to activate and deactivate scheduled reporting of current and historical performance data of the network from the EM-OSF. The parameters used for monitoring shall be configured with network defaults and shall be modifiable where applicable. It shall not be possible to modify any parameters once all monitoring criteria are set and monitoring has been activated without first deactivating.
+- 66 M When a monitoring function is activated, it shall be possible to specify a time period over which performance information is to be recorded. The time period shall be configurable.
+- 67 M The transport function in the OLT, ONU/ONT and NT shall monitor the receive and transmit bit-error rates over the corresponding physical layer to determine the transport integrity. Errors above a configured threshold shall be reported to the EM-OSF.
+- 68 M The NE shall suppress all monitoring intervals that have zero counts within any scheduled report that is sent to the EM-OSF.
+- 69 O Performance monitoring shall involve gathering current and historical statistical data relating to 15-minute intervals over a 24-hour period for the purpose of monitoring and correcting the behaviour and effectiveness of the network.

+
+## **Summary**
+
+This Recommendation provides a CORBA IDL definition for the management interface between a Supplier Management System and an Operator Management System. This work defines part of the management aspects for network resources defined by the G.983.x series of ITU-T Recommendations for Broadband Passive Optical Network (BPON) equipment.
+
+Generally speaking, the Supplier Management System is an Element Management System (EMS) and the Operator Management System (OMS) is a Network Management System (NMS). However, the Supplier Management System is required to present a "network view" of connection management to the Operator Management System. So it was deemed necessary for clarity's sake to use the terminology adopted in naming the systems involved.
+
+In addition, it should be noted that ITU-T Rec. Q.834.1 contains a set of functionality requirements and a listing of managed entity definitions forming the basis for management information required for a "network element view" of BPON equipment. ITU-T Rec. Q.834.2 completes the management information definition for management of BPON equipment by providing the definitions of managed entities for the "network view". ITU-T Rec. Q.834.3 addresses management interface behaviour through use of UML diagrams and Use Case descriptions. The management information modelled in ITU-T Recs Q.834.1 and Q.834.2 is referenced throughout this Recommendation and ITU-T Rec. Q.834.3.

+## **Source**
+
+ITU-T Recommendation Q.834.4 was approved on 7 July 2003 by ITU-T Study Group 4 (2001-2004) under the ITU-T Recommendation A.8 procedure. This edition includes the modifications introduced by Corrigendum 1 approved on 13 January 2004.

+
+## FOREWORD
+
+The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics.
+
+The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation, the expression "Administration" is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.
+
+Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some other obligatory language such as "must" and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# ITU-T Recommendation Q.834.4
+
+# A CORBA interface specification for Broadband Passive Optical Networks based on UML interface requirements
+
+# 1 Scope
+
+This Recommendation addresses the design of an interactive mechanized interface between the Supplier Management System managing BPON network resources and an Operator Management System (OMS). The design is based on the UML diagrams and Use Case descriptions of ITU-T Rec. Q.834.3. The general approach adopted in ITU-T Rec. Q.834.3, and implemented here, is that the Supplier Management System provides management services to the Operator Management System. These services provide the OMS with a high level abstraction of the following capabilities:
+
+- Provisioning installed network resources;
+- Provisioning uninstalled network resources including capacity reservation;
+- Service provisioning;
+- Archive management;
+- NE software management;
+- NE configuration data backup and restoral;
+- Performance management;
+- NE event publication;
+- Profile management;
+- Testing;
+- Activity scheduling;
+- Bulk transfer management;
+- NE-EMS synchronisation;
+- Access control.
+
+This Recommendation describes the CORBA IDL interfaces supporting the services listed above.

+# 5 Conventions
+
+There are two clauses in this Recommendation where specific conventions have been followed. The first is the description of the IDL Modules in clause 8 and the second is the IDL files found in Annex C. Finally, this Recommendation uses certain conventions involving null values.
+
+## 5.1 Module description conventions
+
+Module descriptions have the following pattern:
+
+- Module Name – services overview, including any relevant high-level modelling, key business data element descriptions, and scenarios as required.
+  - Interface Name – overview of the specific services provided by this interface.
+    - Operation Name<sub>1</sub> – detailed description of the behaviour of this operation including signature of the operation, description of each input parameter, and description of the return value.
+    - ...
+    - Operation Name<sub>n</sub> – detailed description of the behaviour of this operation including signature of the operation, description of each input parameter, and description of the return value.
+    - Exceptions – context-specific conditions that cause the named exceptions to be raised.
+
+## 5.2 IDL file conventions
+
+Each IDL file has the following format:
+
+- **#ifndef \_\_<MODULENAME>\_DEFINED** (module name is the same as the filename);
+- **#define \_\_<MODULENAME>\_DEFINED**
+- **#include "<idlfilename>"<sup>1</sup>**
+- **#pragma prefix "itu.Int"**
+- **module q834\_4 {**
+- **module <modulename> {**
+- all the specific data type definitions and interface specifications needed and indicated by the interface design initiated from examination of ITU-T Rec. Q.834.3;
+- **}; //module <modulename>**
+- **}; //module q834\_4**
+
+Within each module definition, data type definitions precede and are segmented from the interface definitions. All data types defined in this Recommendation start with an initial capitalized alpha character. If data type names are joins of several proper nouns, pronouns, or adjectives, the join will expect a capitalized alpha character at the start of each component. Labels for parameters used in any interface operation signature start with a lower case alpha character. Each operation name begins with a lower case alpha character.
+
+---
+
+<sup>1</sup> Q834Common.idl file is included with every other IDL file in this Recommendation.
+
+## 5.3 NULL values
+
+In this Recommendation, when there is a mention of "null string", it is meant to be an empty string and not a null object supported by languages such as JAVA. Similarly, when a "null sequence" is mentioned, a sequence with zero elements is passed.
+
+# 6 Interface architecture overview
+
+Figure 1 illustrates the BPON network architecture and management system. This technology provides an integrated loop access delivery mechanism for every telecommunications service currently deployed by operators. A list of such services includes telephony and voice grade services, circuit-emulation, Ethernet, ATM, xDSL, and video. This standardization effort is ongoing in its consideration of layer 1 and 2 transport solutions on the ODN, although initial implementations exist in operator networks involving APON and ATM as defined in ITU-T Rec. G.983.1.
+
+The figure also shows the IF1 (Q) interface between the Supplier Management System and Operator Management Systems. The IF1 interface covers all aspects of network and service provisioning management, network performance management, traffic management, maintenance, testing, and user security administration. Specification of IF1 would have been an overwhelming challenge if the approach adopted had not pursued a level of abstraction above the transport delivery technology details as well as the complexities inherent in managing so many service types. The approach included the definition and description of interface requirements using Unified Modelling Language, followed the methodology of ITU-T Rec. M.3020, and was documented in ITU-T Rec. Q.834.3.
+
+The operator systems identified in this diagram correspond directly to system actors defined in ITU-T Rec. Q.834.3. This Recommendation specifies the interactive real-time transactions involving the Supplier Management System and does not explicitly describe the file structures transferred between the Supplier Management System and either the Data Warehouse or Secure File Server. Since the interfaces to OMG Naming Service and OMG Notification Service are already specified, the focus of this Recommendation narrows down to messaging between the Supplier Management System and the shaded system actors.
+
+![Figure 1/Q.834.4 – Interface architecture overview. This diagram illustrates the interface architecture of a Supplier Management System (SMS). The SMS is a central oval connected to several external entities: Data warehouse, Secure file server, Privileged user, Profile object repository, Other OMSs, OMS notification service, and OMS naming service. Dashed lines labeled 'IF1' connect the SMS to the Data warehouse, Secure file server, and OMS notification service. A dashed line labeled 'Non Real-time' connects the SMS to the Secure file server. A dashed line labeled 'Real-time' connects the SMS to the OMS naming service. The SMS is also connected to an OLT (Optical Line Terminal) within a dashed box labeled 'BPON network elements'. The OLT is connected to an ODN (Optical Distribution Network) oval, which is then connected to a stack of ONUs (Optical Network Units). The ONUs are connected to a stack of NTs (Network Terminals) via an NNI (Network to Network Interface). The NTs are connected to a stack of ONTs (Optical Network Terminals) via a UNI (User-Network Interface). The ONTs are connected to a stack of ONTs via a UNI.

+
+# 7 Names and naming constraint
+
+This clause provides guidelines for object names and managed entity identifiers referenced on IF1.
+
+Review of all the class diagrams developed in ITU-T Rec. Q.834.3 shows that the Supplier Management System manages three distinct types of "objects". These can be classified as follows:
+
+- **Service Objects:** provide access to the management services implemented in the Supplier Management System. The interfaces of these services are the main subject of this Recommendation. A few examples are NERegistrar, ServiceProvisioner, TestActionPerformer, and DownloadMgr. They are aligned with ITU-T Rec. X.780 as derivations of Managed Object Interface in this Recommendation.
+- **Domain Objects:** define the management information for management of BPON network resources. Domain objects are primarily resources (managed entities) identified by ITU-T Recs Q.834.1 and Q.834.2. These domain objects, as well as others defined in ITU-T Rec. M.3120 and other Recommendations following the CORBA Framework of ITU-T, may be made available for use on IF1. A mechanism for harmonizing the use of Service Objects and Domain Objects is explained later on in this clause.
+
+- Internal Objects: used to support Supplier Management System internal logic. They are completely obscure from the point of view of the OMS.
+
+## 7.1 Service objects and OMG naming service
+
+All Service objects (either instantiated by the Supplier Management System or the OMS) have their IDL interface defined in this Recommendation and their object reference registered with the OMG Naming Service pictured in Figure 1 using the bind() operation of Naming Service interface. Subsequently, the location of the object instance can be found using the resolve() operation of Naming Service, if required.
+
+Object names can be either "well known" (meaning that the name has been documented and agreed to prior to runtime), or communicated at run-time through another interface. In the case of this Recommendation, all of the Service objects are "well-known". The name of a well-known object can be documented via a naming graph. Figure 2 provides an example of a naming graph for some of the Service Objects in this Recommendation, following the naming convention described in ITU-T Rec. Q.816. Shown in the diagram is the Id, followed by a dot, followed by the Kind value. Only four of the Service Objects are shown, for the sake of simplicity, in the figure. The other Service Objects would be named in an analogous fashion.

+
+**Figure 2/Q.834.4 – Naming graph**
+
+The complete path for the name is required for a "well known" object. At start-up of a newly installed Supplier Management System, all instances of Service objects are automatically registered to a single OMG Naming Service maintained by the Operator. The Name of any object registered with OMG Naming Service has the following syntax:
+
+```
+
+typedef      string      Istring;
+
+struct NameComponent {
+    Istring id;
+    Istring kind;
+};
+
+typedef sequence<NameComponent> Name;
+  
+```
+
+One interpretation of the naming graph of Figure 2 is that the "kind" field in each of the naming components of the service objects has the value of null string, and that each of the nodes shown
+
+represents the values for the "id" field. The details of the naming graph, as well as its interpretation, should be determined via agreement between the supplier and operator and these details lie outside the scope of this Recommendation.
+
+## 7.2 Domain objects
+
+The Supplier Management System maintains a large number of Managed Entities (or Domain Objects)<sup>2</sup>. These entities are managed indirectly through the management services offered by the Supplier Management System. However, references (identifiers) to specific resources instances are often needed for the OMS to make effective use of the management services of the Supplier Management System. When the identifier is returned as result of a management operation (or included in notifications) it is assumed that the identifier is "known" in subsequent management service invocations from the OMS. In this specification, the identifier of a Managed Entity has been provided a syntax that allows the Supplier Management System to inform the OMS of at least one of three ways to interact with the Managed Entity in subsequent invocations. If the Managed Entity is a Managed Object available on IF1, then the CORBA name of the object is provided as described in ITU-T Rec. X.780. If the Managed Entity has a supporting Façade object available on IF1, then the CORBA name of the façade object is provided as described in ITU-T Rec. X.780.1. If neither of these capabilities is available yet, then the identifier consists of a reference unique within the context of the management domain of the Supplier Management System. In general, details of this reference are based on a specific containment hierarchy determined via agreement between the supplier and operator and the details lie outside the scope of this Recommendation.
+
+# 8 Organization of IDL files
+
+The proposed interface specification found in this Recommendation consists of a parent module called "q834\_4". The parent module is partitioned into IDL files (smaller modules) corresponding to smaller named modules. Each of these files contains one or more interface definitions representing a specific management service supported on IF1. Table 1 provides a listing correlating Annex C Reference number, IDL File Name, contained IDL Interfaces, and reference to the associated Use Case Description of ITU-T Rec. Q.834.3.

+
+<sup>2</sup> If the Supplier Management System manages 100-200 BPON systems (desirable sizing requirement) and fully supports the shared management knowledge base contained in ITU-T Recs Q.843.1 and Q.834.2, then the number of managed entity instances supported by the Supplier Management System varies between 10s of millions to billions depending on the service offerings.

+# **9 Modules**
+
+## **9.1 AccessControl module**
+
+This module describes functionality for creating, deleting, assigning, and using access control information for operators using the GUI client application of the Supplier Management System. In this module, users can be assigned to user groups. Permission can be granted to individual users or to user groups. The user possesses the permission of any group to which he or she has been assigned. Any individually defined permission (see 9.1.1.14 and 9.1.1.15) for a specific user takes precedence over a group assignment. With group assignments the highest level of permission prevails for any user assigned to the groups. It is assumed that the privileged user does not request any ambiguous target activities when creating or modifying a user group, or when specifying the permission for an individual user.
+
+A target activity is defined as shown in Table 2, throughout the module:
+
+**Table 2/Q.834.4 – Target activity detail**
+
+| Field name               | Definition                                                                                                                       | Syntax    | Comments                                                          |

+
+### 9.1.1 AccessControlMgr interface
+
+#### 9.1.1.1 setPasswordPolicy
+
+This operation allows the privileged users to manage the password policy.
+
+The operation signature for **setPasswordPolicy** is shown below:
+
+```
+void setPasswordPolicy (in PasswordPolicyType passwordPolicy)
+    raises (AccessDenied);
+```
+
+The input parameter **passwordPolicy** identifies the password policy which is enforced by the Supplier Management System and it consists of UserLoginPolicy and SessionPolicy. UserLoginPolicy dictates the following parameters regarding userId and password: minimum size for user Id, minimum size for user password, length of time in days before a password can be reused, maximum number of login attempts allowed before the user access is blocked for a day, how long the password is valid (in days), whether the password must contain an alphanumeric mixture, whether or not at least one special character is required, whether or not the password can contain repeating characters, and whether or not the user Id can be part of the password.
+
+SessionPolicy identifies the following parameters regarding the session: length of time that a session is inactive before the session is discontinued, length of time an inactive user Id is disabled, and the maximum number of active sessions per user Id is permitted.
+
+Since only one passwordPolicy can exist in a Supplier Management System, there is no need to have a create method, either a default policy exists in the Supplier Management System or the first set method can act as set-by-create.

+
+#### 9.1.1.7 createUserGroup
+
+This operation allows the privileged users to create a new user group. User group is used to give certain users certain accesses to certain network elements. The privileged user creates the new group providing the list of the activities allowed to the user group.
+
+The operation signature for **createUserGroup** is shown below:
+
+```
+void createUserGroup (  
+    in UserLabelType userGroupId,  
+    in TargetActivitySeqType targetAdditions)  
+    raises (DuplicateUserGroupId, UnknownTargets, AccessDenied);
+```
+

This allows for example the raising of the permission level of a given activity.
+
+The operation signature for **modifyUserGroup** is shown below:
+
+```
+TargetActivitySeqType modifyUserGroup (  
+    in UserLabelType userGroupId,  
+    in TargetActivitySeqType targetAdditions,  
+    in TargetActivitySeqType targetDeletions)  
+    raises (UnknownUserGroupId, UnknownTargets,  
+    AccessDenied);
+```
+
+The input parameter **userGroupId** identifies the user group to/from which an operator wants to add/delete target activities. The input parameter **targetAdditions** identifies the TargetActivities which need to be added to the group. The input parameter **targetDeletions** identifies the TargetActivities which need to be deleted from the group.
+
+The return value is of type **TargetActivitySeqType** that provides the updated list of TargetActivities which are allowed to the users belonging to this user group.
+
+#### 9.1.1.9 deleteUserGroup
+
+This operation allows the privileged users to delete an existing user group. The deletion can be completed only if the user group is empty.
+
+The operation signature for **deleteUserGroup** is shown below:
+
+```
+void deleteUserGroup (  
+    in UserLabelType userGroupId)  
+    raises (AccessDenied, UserGroupNotEmpty, UnknownUserGroupId);
+```
+
+The input parameter **userGroupId** identifies the group to be deleted.
+
+The return value is of type **void**.

+void addUsersToGroup (  
+    in UserLabelType userGroupId,  
+    in UserIdSeqType userIdList)  
+    raises (AccessDenied, UnknownUserGroupId);
+```
+
+The input parameter **userGroupId** identifies the group to which new users need to be added. The input parameter **userIdList** identifies a set of userIds which need to be added to the existing user group.
+
+The return value is of type **void**.
+
+#### 9.1.1.11 deleteUsersFromGroup
+
+This operation allows the privileged users to delete users from a user group.
+
+The operation signature for **deleteUsersFromGroup** is shown below:
+
+```
+void deleteUsersFromGroup (
+    in UserLabelType userGroupId,
+    in UserIdSeqType userIdList)
+    raises (AccessDenied, UnknownUserGroupId, UnknownUserIds );
+```
+
+The input parameter **userGroupId** identifies the group from which users need to be deleted. The input parameter **userIdList** identifies a set of userIds to be deleted from the user group.
+
+The return value is of type **void**.
+
+#### 9.1.1.12 getPermissionList
+
+This operation allows the privileged users to obtain the list of the activities allowed to a specified user.
+
+The operation signature for **getPermissionList** is shown below:
+
+```
+TargetActivitySeqType getPermissionList (
+    in UserIdType userId)
+    raises (UnknownUserIds, AccessDenied);
+```
+
+The input parameter **userId** identifies the user whose allowed TargetActivities the privileged user wants to obtain.
+
+The return value is of type **TargetActivitySeqType** that provides the list of the TargetActivities which are allowed to a specified user.
+
+#### 9.1.1.13 modifyPermissionList
+
+This operation allows the privileged users to modify the list of the activities allowed to a user. The privileged user specifies the userId and the list of the activities which need to be added or deleted. The Supplier Management System processes the deletions before the additions. This allows, for example, the raising of the permission level of a given activity.
+
+The operation signature for **modifyPermissionList** is shown below:
+
+```
+TargetActivitySeqType modifyPermissionList (
+    in UserIdType userId,
+    in TargetActivitySeqType targetAdditions,
+    in TargetActivitySeqType targetDeletions)
+    raises (UnknownUserIds, UnknownTargets, AccessDenied);
+```
+
+The input parameter **userId** identifies the user whose allowed activities the privileged user wants to modify. The input parameter **targetAdditions** identifies the allowed activities which need to be added to a specified user. The input parameter **targetDeletions** identifies the allowed activities which need to be deleted from a specified user.
+
+If a user belongs to multiple groups that have the same activity, then the user assumes the access level that is the highest. When both the user and the group the user belongs to are added to the same administration domain, then the users activityLevel takes precedence over the group's activityLevel.
+
+The return value of type **TargetActivitySeqType** provides the list of the activities which are allowed to a specified user after the modification.
+
+#### 9.1.1.14 **createUser**
+
+This operation allows the privileged users to create a new user. The privileged user provides a new **userId**, its password, and the list of the activities allowed to the user.
+
+The operation signature for **createUser** is shown below:
+
+```
+void createUser (
+    in UserIdType userId,
+    in PasswordType password,

+
+## 9.2 Build module
+
+The Supplier Management System builds management model groupings for planned equipment on request of an OMS or Operator as part of preprovisioning activities. These resources include nodes (OLT, ONT, ONU, NT) and plug-in units. If equipment is installed, modify operations are used to complete the provisioning of the installed resources. Protection groupings are established for either preprovisioned or installed resources.
+
+### 9.2.1 Builder interface
+
+#### 9.2.1.1 buildNode
+
+This operation builds a NE in the Supplier Management System. A set of managed entities is automatically created in the management information model maintained by the Supplier Management System as a result of this operation. Depending on the equipment implementation of the supplier, instances of equipmentHolderF for shelves and slots, instances of NEFSAN, and instances of physicalPathTPF for integrated ports, are examples of what can be automatically created.
+
+If the NE is an ONT or ONU, this activity automatically removes the bandwidth necessary to support the embedded operations channel between the OLT and ONT or ONU from the available system bandwidth.
+
+The operation signature for **buildNode** is shown below:
+
+```
+ManagedEntityIdType buildNode (  
+    in NEKindType nEKind,  
+    in string supplierName,  
+    in string location,  
+    in VersionType version,  
+    in SerialNumType serialNum,  
+    in NameSeqType alarmSeverityProfiles,  
+    in NameSeqType thresholdDataProfiles,  
+    in SlotAssignmentSeqType slotAssignmentList,  
+    in ManagedEntityIdType port,  
+    in string modelCode,  
+    in string systemTitle,  
+    in VersionSeqType softwareVersions,  
+    in UserLabelType nEUserLabel,  
+    in ExternalTimeType externalTime,  
+    in SystemTimingType systemTiming,  
+    in AdministrationDomainType administrationDomain)  
+    raises (UnrecognisedVersion, InvalidSerialNumSyntax,  
+    DuplicateSerialNumber, UnknownProfiles,  
+    UnknownManagedEntity, DuplicateUserLabel, AccessDenied,
+```
+
+```
+InvalidExternalTime, UnknownSystemTimingSource,  
+ProfileSuspended);
+```
+
+The input parameter **nEKind** identifies the type of NE to be built. Possible choices of NE type are: OLT, ONT, ONU, or NT. The inputs **supplierName** and **version** identify the NE vendor and the hardware version of the NE to be built. The input parameter **location** designates the physical location of the planned NE. The input **serialNum** provides a unique string corresponding to the NE. The input **alarmSeverityProfiles** identifies profiles to configure alarm severity for individual alarms to be reported by the NE. The input **thresholdDataProfiles** identifies profiles to be used when configuring threshold values to generate TCAs from the NE. The input **slotAssignmentList** identifies acceptable plug-in unit assignments for the slots of the NE. If a slot number is not mentioned in the list, then the assumption is made that no assignment has been made for it and, therefore, there are no restrictions on the type of card that can be placed in the slot. The same is true if the value of the plugIn is the empty string. The input **port** identifies the PON port of the OLT if the NE under construction is either an ONT or ONU. The input **port** identifies the port of the ONU serving the NT if an NT is under construction. In case of building an OLT, the value for **port** is null. The input **modelCode** provides a unique string identifying the type of network resource. This input parameter is primarily of interest when pre-provisioning an ONT or NT. The input **systemTitle** identifies an operator-defined label to be applied to the node. The input **softwareVersions** identifies the versions of software to be used by the node. The input **nEUserLabel** provides a unique operator designation for the constructed NE. The input **externalTime** sets current time expressed in generalized time for the NE. The input **systemTiming** identifies the input clock source of the NE that will be used for timing synchronisation. Whenever unspecified is passed for the "enum" data type **systemTiming** from the OMS, the NE shall use its default timing source. The input **administrationDomain** identifies the domain to which the NE belongs.
+
+The return value of type **ManagedEntityIdType** provides an identifier for the new NE created by the operation.
+
+#### 9.2.1.2 assignUserLabelsToNE
+
+This operation assigns operator administrative designations to NEs. This operation is required when the OMS first learns of the NE through autodiscovery.
+
+The operation signature for **assignUserLabelsToNE** is shown below:
+
+```
+void assignUserLabelsToNE (

+    InvalidExternalTime, ProfileSuspended );
+```
+
+The input **managedEntityId** identifies the target NE to be modified. The **newSlotAssignmentList** identifies a new assignment of acceptable plug in units for the slots of the NE. If a slot number is not mentioned in the list, then the assumption is made that there is no change for the assignment of that slot. If the value of the plugIn is the empty string then there are no restrictions on the type of card that can be placed in the slot and if a plug-in unit is subsequently removed from the slot no removal alarms are raised. The input **alarmSeverityProfiles** identifies profiles to configure alarm severity for individual alarms to be reported by the NE. The input **thresholdDataProfiles** identifies profiles to be used when configuring threshold values to generate TCAs from the NE. The input **port** identifies PON port on the OLT if there is a change in the relationship between the planned ONT or ONU and the OLT port. The input **port** identifies the ONU port if there is a change in the relationship between the planned NT and ONU port. The input **newModelCode** provides a unique string identifying the type of network resource. This input parameter is primarily of interest when modified node is an ONT or NT. The input **newNEUserLabel** provides a new User Label to be applied to the NE. The input **externalTime** gives a new current reference time for the NE.

+## 9.3 Q834Common module
+
+This module contains the definitions of data types used by more than one of the other IDL modules in this Recommendation. It also provides three groupings of constants. Many of the data types mentioned in Q834Common are imported from ITU-T Rec. X.780. The most important aspect of this IDL file is the definition of ManagedEntityIdType. The definition is extracted from the IDL file and presented below for discussion purposes.
+
+```
+struct NamingComponentType {
+    string type; // managed entity type
+    string id;
+};
+
+typedef sequence<NamingComponentType> RDNTType;
+typedef sequence<RDNTType> RDNSeqType;
+typedef sequence<NameType> NameSeqType;
+
+enum IdType {
+    none,
+    x780_fineGrained,
+    x780_coarseGrained
+};
+
+typedef RDNTType MEIdType;
+```
+
+```
+
+struct ManagedEntityIdType {
+    IdType id;
+    MEIdType mEId;
+};
+
+```
+
+ManagedEntityIdType is a return value for many of the operations throughout this Recommendation. Examining the definition of this data type (reading from bottom to top) shows that the Supplier Management System returns a value providing a reference either to a fine-grain Managed Object, a coarse-grain Façade, or a RDN identifier for a data structure within the Supplier Management System. In all three cases, the fundamental syntax for the mEId is a sequence of pairs of naming components which is the syntax employed by ITU-T Rec. X.780 for Managed Objects and the syntax employed by ITU-T Rec. X.780.1 for Façades.
+
+### 9.3.1 ProbableCauseConst Module and ProbableCause interface
+
+This module definition follows the pattern specified in ITU-T Rec. X.780 and uses the same syntax for the values of probable cause. It provides some technology-specific values in addition to the values defined in ITU-T Rec. X.780.
+
+### 9.3.2 MonitoringParameter interface
+
+This interface provides the names for monitored performance and traffic parameters to be used by interfaces AlarmEventSupplier, ImpairmentPersistence and ProfileConsumer. The MonitoringParameter values are expressed as a string of values and are part of filterable data in a structured event.
+
+### 9.3.3 RecordSetType interface
+
+This interface provides the data value(s) to be used for recordset data type value by interfaces ReportController and RecordSetMgr. The recordSet type values are expressed as unsigned short values. The Values 1-99 are reserved for HistoryDataType.
+
+### 9.3.4 PhysicalLayerLoopback interface
+
+This interface provides the data value(s) to be used for loopbackTestType data type value by the TestActionPerformer interface. The recordSet type values are expressed as unsigned short values.
+
+## 9.4 ControlArchive module
+
+The Supplier Management System provides the functionality to manage logs for specific groups of events including the clearing of the contents of the logs. The Privileged User can create, initialize, suspend, resume, and remove event logs. The Supplier Management System also provides the functionality to control the short-term archiving of performance monitoring and traffic monitoring reports, including the clearing of contents of these record sets. This function also includes the reporting of status for current logs or statistics record sets. The majority of short-term archives within the Supplier Management System are created automatically when the Supplier Management System is first instantiated. The names of these archives, identified by ManagedEntityIdType syntax, can be provided by the supplier to the operator or obtained by invocation of the operation recordSetListGet with creationModeType value "initialList" and iterative invocations of the operation getStatusAttributes for each record set identified in the first operation.
+
+### 9.4.1 RecordSetMgr interface
+
+#### 9.4.1.1 createLog
+
+CreateLog operation is used to create a RecordSet in the Supplier Management System for the purposes of archiving event information.
+
+The signature of **createLog** is as follows:
+
+```
+ManagedEntityIdType createLog (  
+    in UserLabelType recordSetUserLabel,  
+    in AdministrativeStateType administrativeState,  
+    in NameType filterName,  
+    in FullActionType fullAction,  
+    in MaxSizeType maxSize,  
+    in SizeThresholdType sizeThreshold)  
+    raises (RecordSetExists, DuplicateUserLabel, AccessDenied);
+```
+
+The input parameter **recordSetUserLabel** uniquely identifies the recordSet within the Supplier Management System. The input parameter **administrativeState** specifies if the new log is initialized for recording of event information. The input parameter **filterName** explains the entrance criteria determining what event notifications are recorded in the log to be created. If the **filterName** is unrecognized by the Supplier Management System, it looks up the IOR for the filterObject using **filterName** by consulting the directory of Naming Service. Using the IOR, the system is then able to retrieve the entrance criteria details from CosNotifyFilter interface available on Notification Service. The input parameter **fullAction** specifies the behaviour of the recordset when it reaches its maximum size. The input parameter **maxSize** specifies the maximum size of the recordSet. The input parameter **sizeThreshold** specifies the threshold on size of the RecordSet which triggers the Supplier Management System to generate an alarm/event.
+
+The return value is of type **ManagedEntityIdType** and provides the identifier for the log archive created with this operation.
+
+#### 9.4.1.2 createArchive
+
+CreateArchive operation is used to create a recordSet for storing history data. The archiving will halt automatically its recording when it hits the maximum size.
+

+
+The exception **UnknownRecordSet** is raised if the designated record set is unknown to the Supplier Management System.
+
+## **9.5 SoftwareDownload module**
+
+The software download process consists of four phases: delivery, distribution, installation (commit), and activation. The Supplier Management System supports these stages for the download of software generic programs, software upgrades, and software maintenance changes (patches) to NEs in this module. The Supplier Management System can accept requests involving one or multiple NEs at once. All software management activities can be individually scheduled. Any request for downloading software generics is accompanied by security credentials whereby the Supplier Management System is allowed to communicate with the source server. Which security credentials are being used depends on implementation: If the software load is resident on the EMS and the EMS will push it (through file transfer) to the NE, then the credentials are for the NE. If the software load is resident on the EMS and the NE will pull, then the credentials are for the EMS. If the software load is resident on a separate repository, then the security credentials are for the separate repository and the NE pulls the load from the repository.
+
+Requests for a software management activity may generate the creation of a software management tracking object. This lifecycle of this object must extend until all associated activities are completed successfully or unsuccessfully. The object is only deleted after a predefined retention period and the length of time of the retention period is agreed to outside the scope of this interface. The retention period for the tracking object should be generous enough to include any revert activity desired. If the tracking object has been automatically deleted by the Supplier Management System, then the revert activity is viewed as download activity of a previous software load. The OMS can also delete this tracking object before its automatic termination if desired.
+
+The Supplier Management System creates a log record for every software distribution activity including delivery, commitment, and activation, regardless of the result of the activity. The record contains detailed results for every affected target including start/stop times and success or failure indication.
+
+The Supplier Management System maintains a current listing of all software activities in progress.
+
+This module also includes support for retrieval of hardware and software version information from installed NEs. It is also possible to verify that a software set may be downloaded to a NE or to a specific plug-in unit.
+
+### **9.5.1 DownloadMgr interface**
+
+#### **9.5.1.1 deliverDistSWGlobal**
+
+This operation requests the Supplier Management System to download software generics from a software source machine for the purpose of software upgrades and software maintenance changes (patches) to NEs. The Supplier Management System can accept requests for one or multiple NEs at once. The operation is best effort, meaning the Supplier Management System attempts to execute the delivery and distribution to all specified targets. As appropriate, it continues to attempt to
+
+---
+
+<sup>4</sup> This size to be agreed upon by supplier and operator in advance.
+
+deliver and distribute software to all named targets, even when it encounters a failure in either process for a specific target. The activity completion log is used to record successes and failures of both the delivery and distribution attempts. The `SoftwareDownloadTrackingObject` continues to be available for commit, activate attempts and those activities are only attempted for targets where the delivery and distribution was successful. The `SoftwareDownloadTrackingObject` is retained beyond the successful activation stage (in part to allow for revert activities if required).
+
+Subsequently, if a new ONT is ranged, or if a broken fibre connection is repaired, or if a new plug-in unit is installed, and in each of these cases the active software load differs from that specified in this operation, then the Supplier Management System (or network resource) will be responsible for upgrading the software automatically.
+
+The signature of the operation **deliverDistSWGloab** is provided below:
+
+```
+SoftwareDownloadTrackingObjectIdType deliverDistSWGloab (
+    in FilenameSeqType softwareSet,

+## 9.7 MIBTransfer module
+
+This module manages the process for collection of system configuration data to be used to restore a system in the event that a catastrophic failure condition has occurred. The collection of the configuration data can be done either on a real-time or on a scheduled basis. It also provides status information for backup and restoral processes in progress. The results of backup and restore processes are logged by the Supplier Management System. Any request to backup or restore configuration data is accompanied by security credentials whereby the Supplier Management System or OLT is allowed to communicate with the external server. While the backup is progress, all provisioning requests involving the designated OLT system are rejected/blocked. Transfer Tracking Objects are automatically deleted by the Supplier Management System once the associated file transfer(s) have finished and results (whether successful or unsuccessful) are recorded in the completion log.

+## 9.8 PerformanceManager module
+
+The Supplier Management System shall provide for the activation and deactivation of performance data or traffic measurements reporting on individual termination points contained in the NEs as required by the operator or OMS for OLTs that have been installed. Requirements for the Supplier Management System found in this Recommendation also include provision for the setting of threshold values and describe automatic reporting of performance measurements to the Supplier
+
+Management System when thresholds have been crossed. When there is an occurrence of a set of Threshold Crossing Alerts associated with a single performance degradation condition, the Supplier Management System shall analyse and correlate the alert events within its domain to the best of its ability, determine the underlying root cause of the problem, and store this information in a log. If several occurrences of the same root cause impairment are detected within a period of time, the Supplier Management System shall prepare a QoS alarm record for publication any interested consumer (Operator or OMS). If the Supplier Management System can collect all the history data records for all the monitoring points<sup>5</sup> for all the network elements in its management domain, there is no need for reporting control. In this case, it is assumed that reporting is constantly available.
+
+### 9.8.1 ImpairmentPersistence interface
+
+Throughout this Recommendation, it is assumed and required that profile objects that are of threshold data type<sup>6</sup> are groupings of threshold values can be associated with one, and only one, type of monitoring point.
+
+#### 9.8.1.1 setSlidingWindowParameters
+
+This operation sets the sliding window parameters for one, some or all monitored parameters in an NE. This setting is applied for all points monitoring the parameters. Subsequently, the Supplier Management System generates a QoS alarm if a monitoring point detects a TCA **persistenceMinimum** times within **totConsecutiveIntvls** consecutive monitoring intervals. This operation is best effort.
+
+The exception **CommFailure** is raised if the Supplier Management System is unable to communicate with the NE identified in the operation, and if the sliding window parameter values are set directly on network resources.
+
+This operation is used to establish system-wide default settings if the indicator **sysScopeInd** has the value **TRUE** and the **nManagedEntityId** is the identifier for an OLT. This means that the sliding window parameter values are to be applied to all monitoring points of any equipment components currently or potentially belonging to the system with the named OLT headend. If the OLT has lost communications with any subtending network resource prior to or during invocation of this operation, it is up to supplier implementation to guarantee that the settings are applied once communication is established. If the indicator **sysScopeInd** has the value **TRUE** and the **nManagedEntityId** is the identifier for an ONU, then the settings are viewed to apply to the ONU and all NTs subtending from it. As equipment components are added to the system with headend of OLT or ONU, the Supplier Management System automatically sets these parameter values.
+
+If **sysScopeInd** has the value **FALSE**, then the sliding window parameter settings are to be applied only to the indicated resource. The settings are still applied to both existing and potential equipment components of the node.
+
+The operation signature for **setSlidingWindowParameters** is shown below:
+
+```
+void setSlidingWindowParameters (

+
+This operation allows the setting of a collection of threshold value, monitoringPointType pairs on a particular NE. The exception CommFailure is raised if the Supplier Management System is unable to communicate with the NE identified in the operation, and if threshold values are set directly on network resources.
+
+This operation is used to establish system-wide default settings if the indicator sysScopeInd has the value TRUE and the nManagedEntityId is the identifier for an OLT. This means that the threshold values are to be applied to all monitoring points of any equipment components currently or potentially belonging to the system with the named OLT headend. If the OLT has lost communications with any subtending network resource prior to or during invocation of this operation, it is up to supplier implementation to guarantee that the settings are applied once communication is established. If the indicator sysScopeInd has the value TRUE and the nManagedEntityId is the identifier for an ONU, then the settings are viewed to apply to the ONU and all NTs subtending from it. As equipment components are added to the system with headend of OLT or ONU, the Supplier Management System automatically sets these threshold values.
+
+If sysScopeInd has the value FALSE, then the threshold settings are to be applied only to the indicated resource. The settings are still applied to both existing and potential equipment components of the node.
+
+The operation signature for **setThresholds** is shown below:

+## 9.9 ProfileManager
+
+This module consists of three interfaces: ProfileConsumer, ProfileUsageMgr, and ProfileRetriever. ProfileConsumer specifies the contents of event notification for profile creations within the Profile Object Repository. ProfileUsageMgr supports operations to manage profile settings cached within the Supplier Management System. ProfileRetriever allows Supplier Management System to obtain the values for profile settings.
+
+### 9.9.1 ProfileConsumer Interface
+
+The purpose of the interface is to announce the existence of new profile settings and to convey those settings to the Supplier Management System. This interface has no operations. However, it does provide the fixed header mapping as well as the filterable data mappings for the structured event object used to push event information through the event channel of the OMG Notification Service.
+
+In the fixed header, the **domain\_type** is set to "telecommunications", the **type\_name** is set to "ProfileEvent", and the **event\_name** is set to a constant string that has the value "ProfileCreation" as defined in the interface.
+
+The mapping in the filterable data follows a strategy using a constant string identifier for the filterable data component followed by the value for that data element. Also, the filterable data items are listed in a specific order.
+
+The order of the filterable items is ProfileName, ProfileType, EventTime, ProfileAttributeValues, and NotificationIdentifier. ProfileName value has the syntax of NameType. ProfileType value has the syntax "unsigned short", and it allows the consumer (Supplier Management System) to identify the type of profile created and to unmarshal the attribute values found later in profileStruct. The syntax of ProfileAttributeValues is profileStruct. EventTime has the syntax of GeneralizedTimeType, and it is the time that the profile was created. NotificationIdentifier has the syntax of NotificationIdentifierType. This identifier uniquely labels the profile creation event and is incremented with each profile creation.

+## 9.10 Registrar module
+
+This module supports the process of bringing a new NE into the management jurisdiction of the Supplier Management System. It supports both initial installations and equipment replacements motivated by maintenance or service upgrades. It explicitly supports the ranging function that is used to measure the round trip delay between the OLT and each ONU or ONT and establish security mechanisms (churning key algorithm) and communication timing including automatic setup of the embedded operations channel.
+
+A set of managed entities is automatically created in the management information model maintained by the Supplier Management System as a result of registration. Depending on the equipment type, instances of OLT, ONT, ONU, APONLink, APONTTP, APONTrail, APONNetworkCTP, APONNetworkTTP, APONLinkConnection, tcAdapterF, vpLinkConnectionF, vpTopologicalLinkF, and physicalPathTPF are automatically created. Depending on supplier implementation as well as what is physically installed, other managed entities are also automatically created.

+## 9.12 SchedulerManagement module
+
+This service is used to provide OMS interfaces for managing schedulers to be used for invoking various activities. Once the scheduler is created, the OMS can initiate requests to schedule an activity such as NE MIB uploading, bulk transfer, testing, or software downloading by referencing the scheduler. Schedulers are determined by needs of the operations environment. It is assumed that there will be no schedulers named or established automatically upon instantiation of the Supplier Management System. References to a specific scheduler will always be made via User Label. A trigger matrix is used to describe the schedule. The values in the matrix are interpreted based on the value of HourlyDailyWeeklyMonthlyInd.
+
+### 9.12.1 SchedulerMgr interface
+
+#### 9.12.1.1 makeScheduler

+
+The input parameter **networkCharacteristicsProfiles** provides the list of transport related profiles to be used for service provisioning including azTrafficDescriptorProfile and zaTrafficDescriptorProfile. The az Traffic Descriptor Profiles are listed before the za in the listing. The parameter **serviceInstanceId** indicates the service instance identifier to be used as the key when referring to network resources associated with the service. The input parameter **administrativeState** specifies whether or not the subnetwork connection is able to carry subscriber traffic once this operation is executed.
+
+The return value of type **ManagedEntityType** is a managed entity identifier to identify the subnetworkConnection created as the result of this request.
+
+#### 9.13.1.2 provisionReservation
+
+This operation provisions service between the NNI of an OLT and the UNI of an ONT or between two UNIs based on an outstanding reservation. Once the service connection is provisioned, the reserved bandwidth and associated reservation Id is removed from the Supplier Management System because the reserved resources are assigned.
+
+The operation signature for **provisionReservation** is shown below:
+
+```
+ManagedEntityIdType provisionReservation(  
+    in ReservationIdType reservationId,  
+    in AdministrativeStateType administrativeState)  
+    raises ( UnknownReservationId, AccessDenied);
+```
+
+The input parameter **reservationId** specifies the reservation Id. It points to all the other information (such as service instance Id and endpoints) to associate with the provisioned connection. The input parameter **administrativeState** specifies whether or not the subnetwork connection is able to carry subscriber traffic once this operation is executed.

+    in NameSeqType newServiceCharacteristicsProfiles)  
+    raises (UnknownConnection, UnknownProfiles, InsufficientBW,  
+    UnknownPort, AccessDenied, ProfileSuspended );
+```
+
+The input parameter **subnetworkConnectionId** is the subnetwork that was created previously via service provisioning request. The input parameter **portB** helps to clarify the directionality of the traffic descriptor profiles named in the next input parameter as well as to specify where the service profiles are meant to be applied. This port is either the A or Z port of the original connection request. The input parameter **newNetworkCharacteristicsProfiles** provides the modified list of network related profiles to be used for service provisioning where "b-to-opposite endpoint" traffic descriptor profiles are listed before "the opposite endpoint-to-b" traffic descriptor profiles. The input parameter **newServiceCharacteristicsProfiles** provides the new list of service related profiles.
+
+The return value of type **ManagedEntityIdType** is a managed entity identifier to identify the subnetworkConnection created as the result of this request.
+
+#### 9.13.1.5 suspendService

+    raises (UnknownServiceInstance, AccessDenied, InvalidStartTime,  
+    InvalidStopTime);
+```
+
+The input parameter **serviceInstanceId** identifies the service connection to be suspended. The input parameter **startTime** provides the time point at which the service is to be suspended. The input parameter **stopTime** provides the time point at which the service is to be resumed.
+
+The return value is of type **void**.
+
+#### 9.13.1.6 resumeService
+
+This operation enables the flow of user traffic through the service subnetwork connection. This operation can be invoked either after service has been suspended (see operation above) or if the original service connection is configured in an inactive state. The service is to be resumed immediately.
+
+The operation signature for **resumeService** is shown below:
+
+```
+void resumeService (  
+    in ServiceInstanceIdType serviceInstanceId)  
+    raises (UnknownServiceInstance, AccessDenied);
+```
+
+The input parameter **serviceInstanceId** identifies the service connection to be resume.

+
+## 9.14 Synchroniser module
+
+This module manages the synchronisation process between the Supplier Management System and a specific NE. The requested synchronisation process can be narrowed to a specific set of current event listings. The details on how inconsistencies are detected and what data is retrieved is up to the suppliers implementation. However, this process results in the removal of any inconsistencies between the management information found with the NE and the information model maintained in the Supplier Management System.
+
+The operations in this module can only be invoked by a privileged user. The synchronisation process is "best effort" in the sense that any inconsistencies detected and corrected prior to a system defined timeout period<sup>10</sup> are preserved. The synchronisation process may impact the performance of the Supplier Management System in a negative way prior to its completion.
+
+When the network element chosen is an OLT, then the synchronisation process is system-wide.
+
+### 9.14.1 NESynchroniser interface
+
+#### 9.14.1.1 synchNE
+
+This operation initiates a synchronisation process between the Supplier Management System and a specific NE. This operation is blocking only as long as it takes for the Supplier Management System to validate that the process can be initiated, and performs the synchronisation operation in the background.
+
+The operation signature for **synchNE** is shown below:
+
+```
+void synchNE(in ManagedEntityIdType nEManagedEntityId)
+    raises (AccessDenied, CommFailure, UnknownNE, EquipmentFailure,
+           BackupInProgress, SynchInProgress);
+```
+
+The input **nEManagedEntityId** identifies NE to synchronise with the Supplier Management System.
+
+---
+
+<sup>10</sup> This timeout period is a matter of agreement between the Operator and the Supplier.
+
+The return value is of type **void**.
+
+#### 9.14.1.2 abortSynchNE
+
+This operation aborts a synchronisation process in progress between the Supplier Management System and a specific NE. Any inconsistencies between the Supplier Management System and the NE that have been resolved before the abort are retained.
+
+The operation can only be invoked by a privileged user.
+
+The operation signature for **abortSynchNE** is shown below:
+
+```
+void abortSynchNE(  
+    in ManagedEntityIdType nEManagedEntityId)  
+    raises (AccessDenied, CommFailure, UnknownNE, EquipmentFailure,  
+    NoSynchInProgress);
+```
+
+The input **nEManagedEntityId** identifies the NE whose synchronisation with the Supplier Management System is to be aborted.
+
+The return value is of type **void**.
+
+#### 9.14.1.3 scheduleSynchNE
+
+This operation schedules a synchronisation process between the Supplier Management System and a specific NE. The scheduled synchronisation process is triggered by the scheduler which is predefined by the operator. At most, one scheduler can be associated with this activity for a specific NE.
+
+The operation signature for **scheduleSynchNE** is shown below:
+
+```
+void scheduleSynchNE(  
+    in ManagedEntityIdType nEManagedEntityId,  
+    in UserLabelType schedulerName)  
+    raises (AccessDenied, UnknownNE, UnknownScheduler, InvalidScheduler);
+```
+
+The input **nEManagedEntityId** identifies the NE to synchronise with the Supplier Management System. The input **schedulerName** identifies scheduler to be used to invoke scheduled synchronisation operation of Supplier Management System.
+
+The return value is of type **void**.
+
+#### 9.14.1.4 modifyNESynchSchedule
+
+This operation modifies the schedule for NE synchronisation. This operation will not interrupt a synchronisation process in progress. If successful, the new schedule is applied with the next iteration.
+
+The operation signature for **modifyNESynch** is shown below:
+
+```
+void modifyNESynchSchedule(  
+    in ManagedEntityIdType nEManagedEntityId,  
+    in UserLabelType newSchedulerName)  
+    raises (AccessDenied, UnknownNE, UnknownScheduler,  
+    InvalidScheduler);
+```
+
+The input **nEManagedEntityId** identifies the NE where the scheduled NE synchronisation is activated. The input **newSchedulerName** identifies the schedule to be applied.
+
+The return value is of type **void**.
+
+#### 9.14.1.5 cancelScheduledSynchNE
+
+This operation cancels all subsequent scheduled synchronisation processes for this NE. This operation will not interrupt a synchronisation process in progress.
+
+The operation signature for **cancelScheduledSynchNE** is shown below:
+
+```
+void cancelScheduledSynchNE(  
+    in ManagedEntityIdType nEManagedEntityId )  
+    raises (AccessDenied, UnknownNE);
+```
+
+The input **nEManagedEntityId** identifies the NE where the scheduled NE synchronisation is activated.
+
+The return value is of type **void**.
+
+#### 9.14.1.6 synchCurrentEventListings
+
+The operation initiates synchronisation between the Supplier Management System and specified NE for items in particular current event listings. The Supplier Management System normally retrieves current values of state, status, or management attributes and tracks these via current summary event listings for the system. If any automatic system retrieval process shows that the listing is not up-to-date with the current conditions of the system, then the listing is modified (through deletion of an entry or insertion of a new entry) in order to correct the listing. This operation is a manual version driven by OMS request. While this operation is in effect, the exception **SynchInProgress** for any other operation may not be invoked.
+
+The operation signature for **synchCurrentEventListings** is shown below:
+
+```
+void synchCurrentEventListings(  
+    in ManagedEntityIdType nEManagedEntityId,  
+    in CurrentListingSeqType currentListingTypeList)  
+    raises (AccessDenied, CommFailure, DCNTimeout, UnknownNE,  
+    EquipmentFailure, Timeout);
+```
+
+The input **nEManagedEntityId** identifies the NE for synchronisation. The input **currentListingTypeList** identifies the list of current event that are to be synchronised between the Supplier Management System and the specified NE. The Supplier Management System retrieves the specified current event listing values from NE.
+
+The return value is of type **void**.
+
+#### 9.14.1.7 scheduledSynchNEListGet
+
+This operation is used to retrieve the names of all NEs with synchronisation schedules.
+
+The operation signature for the **scheduledSynchNEListGet** is shown below:
+
+```
+ScheduledSynchNESeqType scheduledSynchNEListGet ()  
+    raises (AccessDenied);
+```
+
+There are no input parameters.
+
+The return value is of type **ScheduledSynchNESeqType** and provides the listing of NEs desired.
+
+#### 9.14.1.8 Exceptions
+
+The exception **AccessDenied** is raised when the system is not granted access to the interface object.
+
+The exception **BackupInProgress** is raised when the synchronisation request is issued while the backup is in progress.
+
+The exception **CommFailure** is raised when the DCN between the Supplier Management System and OLT or the communication between OLT and subtending ONT or ONU is down.
+
+The exception **DCNTimeout** is raised when the DCN communications link between at least one of the NEs and the Supplier Management System is so congested that current state or status information cannot be transferred within a system defined time period.
+
+The exception **EquipmentFailure** is raised when the equipment where the data is backed up from is in failure condition.
+
+The exception **InvalidScheduler** is raised when the given scheduler is inappropriate for use in this operation, or out-of-date.
+
+The exception **SynchInProgress** will be raised when a new synchNe is requested while either synchNe or scheduledSynchNe is in progress.
+
+The exception **SynchNotScheduled** is raised if no planned synchronisation exists for the NE at the specified time.
+
+The exception **UnknownNE** is raised when the NE mentioned in the request is unknown to the Supplier Management System.
+
+The exception **UnknownScheduler** is raised when the given scheduler name is not found.
+
+The exception **Timeout** is raised when the specified process has exceeded a system-defined default timeout period.
+
+The exception **NoSynchInProgress** is raised if there is no synchronisation process in progress.
+
+## 9.15 Test module
+
+This service is used to provide interfaces for the operator or OMS to perform directed or scheduled testing procedures. Tests such as ATM OAM cell loopback testing, interface loopback set-up on subscriber cards or OLT network interface cards, and ATM continuity checks are specified using this service. Tests can be either scheduled or manually invoked following an identified fault or subscriber service complaint. The TestActionPerformer interface provides the operations to execute tests applicable on network resources.
+
+### 9.15.1 TestActionPerformer interface
+
+#### 9.15.1.1 aTMLoopback
+
+This operation is used to invoke an ATM OAM Loopback test. ATM Loopback test is unidirectional.
+
+The operation signature for the **aTMLoopback** is shown below:
+
+```
+AggregateATMLoopbackResultSeqType aTMLoopback (  
+    in UserIdType testRequestorId,  
+    in ManagedEntityIdType ctp,  
+    in ATMLoopbackInfoType aTMLoopbackInfo,  
+    in TestIterationNumType testIterationNum,  
+    in ServiceInstanceIdType serviceInstanceId)  
+    raises (AccessDenied, CommFailure, UnknownManagedEntity,  
+    NotAvailableForTest, InvalidLocationId, InvalidDirection);
+```
+
+The input parameter **testRequestorId** is used to identify the initiator of the ATM Loopback test. The input parameter **ctp** is used to uniquely identify the CTP for the loopback cell injection point. The input parameter **aTMLoopbackInfo** is used to provide specific ATM test information; the LoopbackLocationId is part of aTMLoopbackInfo. The input parameter **testIterationNum** identifies the iteration number for the ATM loopback test. The input parameter **serviceInstanceId** identifies the possible service instance associated with the loopback test request.
+
+When specifying aTMLoopbackInfo, the only applicable values for directionality are 'egress' or 'ingress' only. The directionality is specified as part of the **aTMLoopbackInfo**.
+
+The LoopbackLocationId identifies the point(s) along a virtual connection where the loopback is to occur. The default value of all ones is used by the transmitter to indicate the end point. When segmentCellInd is set to 'false', the LoopbackLocationId must be set to the default. If no
+
+LoopbackLocationId is provided, it is assumed that there is a designated segment endpoint for the flow associated with the injection ctp.
+
+For ctp, all zeros indicate a loopback request directed at all connection points having a LoopbackLocationId. All ones indicate a loopback request directed at the endpoint (segment or connection endpoint). 'x6A'H indicates no designated CP for loopback, and therefore no loopback should be performed. All other values for LoopbackLocationId indicate a loopback request directed at a specific LoopbackLocationId location.
+
+The return value is of type **AggregateATMLoopbackResultSeqType** which provides information on the test, specifically the loopbackingLLID, responseTime in microseconds, and success/failure for each iteration.
+
+#### 9.15.1.2 initializeContinuityCheck
+
+This operation is used to prepare for an ATM continuity check. The creation of a continuity test environment does not necessarily initiate the test, but rather schedules a test to be initiated. Upon successful creation of a continuity check, the system will return a unique identifier that is used to identify the test.
+
+This operation deals with the test setup only. Once the test is executed, an alarm will be raised in case of a failure.
+
+The operation signature for the **initializeContinuityCheck** is shown below:
+
+```
+CCSetUpIdType initializeContinuityCheck(  
+    in UserIdType testRequestorId,  
+    in ManagedEntityIdType sourceCtp,  
+    in ATMContinuityCheckInfoType aTMContinuityCheckInfo,  
+    in GeneralizedTimeType stopTime,  
+    in ServiceInstanceIdType serviceInstanceId)  
+    raises (AccessDenied, CommFailure, UnknownManagedEntity,  
+    NotAvailableForTest, InvalidStartTime, InvalidStopTime,  
+    InvalidDirection);
+```
+
+The input parameter **testRequestorId** is used to identify the initiator of the test. The input parameter **sourceCtp** and **sinkCtp** is used to identify the A point for the continuity test. The input parameter **aTMContinuityCheckInfo** is used to provide specific continuity test information. The directionality must be set to 'BothDirections' and segmentCellInd is set to 'true' for segment continuity test, and 'false' for end-to-end. The input parameter **stopTime** provides information on how long the test should be executed. The input parameter **serviceInstanceId** identifies the possible service instance associated with the loopback test request.
+
+The return value is of type **CCSetUpIdType** which uniquely identifies the test that was set up. The CCSetUpId for the setup test exists until the stopTime is reached, or until it is explicitly cancelled using the terminateContinuityCheck operation.
+
+#### 9.15.1.3 terminateContinuityCheck
+
+This operation is used to take down the ATM continuity test environment. If the continuity test has already been initiated (i.e., its startTime is reached), the continuity test will stop executing and will then be removed.
+
+The operation signature for **terminateContinuityCheck** is shown below:
+
+```
+void terminateContinuityCheck(  
+    in CCSetUpIdType cCSetUpId)  
+    raises (AccessDenied, CommFailure, UnknownTest);
+```
+
+The input parameter **CCSetUpId** is used to identify the test to terminate.
+
+The return value is of type **void**.
+
+#### 9.15.1.4 **scheduleResourceSelfTest**
+
+This operation is used to schedule a resource self test. This operation is used by the OMS to set up self tests on resources to be executed at a regular basis. Having a scheduler object setup is a prerequisite for initiating this operation.
+
+The operation signature for the **scheduleResourceSelfTest** is shown below:
+
+```
+TestTrackingObjectIdType scheduleResourceSelfTest (
+    in UserIdType testRequestorId,
+    in ManagedEntityIdType targetNE,
+    in unsigned long timeOutPeriod, //In seconds.
+    in ResourceSelfTestInfoSeqType specificTestInfo,
+    in UserLabelType schedulerName)
+    raises (AccessDenied, UnknownNE, UnknownScheduler,
+    InvalidScheduler, InvalidTimeoutPeriod, InvalidTestOperations);
+```
+
+The input parameter **testRequestorId** is used to identify the initiator of the test. The input parameter **targetNE** identifies the network element to perform self test. The input parameter **timeOutPeriod** identifies the maximum time period that the system will allow the test to run on the resource. The input parameter **specificTestInfo** is used to provide supplier-specific self test information regarding each diagnostic test type to be run; this information is provided to the operator via system documentation. The input parameter **schedulerName** is used to reference the applicable scheduler for this test.
+
+The return value of type **TestTrackingObjectIdType** uniquely identifies the scheduled testing. The Test Tracking Object exists until it is explicitly cancelled using the **terminateScheduledResourceSelfTest** operation or if the scheduler end time is reached.
+
+The self test results are logged. The **ResourceSelfTestResultSeqType** data type defines part of the information that is logged.
+
+#### 9.15.1.5 **modifyResourceSelfTestSchedule**
+
+This operation is used to modify the schedule for a regularly conducted resource self test. If successful, the resource self test initiation is changed with the next iteration.
+
+The operation signature for **modifyResourceSelfTestSchedule** is shown below:
+
+```
+void modifyResourceSelfTestSchedule (
+    in TestTrackingObjectIdType testTrackingObjectId,
+    in UserLabelType newSchedulerName)
+    raises (UnknownTest, UnknownScheduler, InvalidScheduler,
+    AccessDenied);
+```
+
+The input parameter **testTrackingObjectId** is used to identify the scheduled test. The input parameter **testTrackingObjectId** is used to identify the new schedule.
+
+The return value is of type **void**.
+
+#### 9.15.1.6 **cancelScheduledResourceSelfTest**
+
+This operation is used to cancel a regularly scheduled resource self test. If successful, this operation cancels the test prior to its initiation with the next trigger time.
+
+The operation signature for **cancelScheduledResourceSelfTest** is shown below:
+
+```
+void cancelScheduledResourceSelfTest (
+    in TestTrackingObjectIdType testTrackingObjectId)
+    raises (UnknownTest, UncontrolledTestInProgress, AccessDenied);
+```
+
+The input parameter **testTrackingObjectId** is used to identify the scheduled test to terminate.
+
+The return value is of type **void**.
+
+#### 9.15.1.7 conductResourceSelfTest
+
+This operation is used to initiate a resource self test following the identification of a system fault or a subscriber service complaint. The test results are logged in the Supplier Management System.
+
+The operation signature for the **conductResourceSelfTest** is shown below:
+
+```
+TestTrackingObjectIdType conductResourceSelfTest (  
+    in UserIdType testRequestorId,

+    in unsigned long timeOutPeriod, //In seconds.  
+    in ResourceSelfTestInfoSeqType specificTestInfo)  
+    raises (AccessDenied, CommFailure, UnknownNE,  
+    InvalidTimeoutPeriod, InvalidTestOperations);
+```
+
+The input parameter **testRequestorId** is used to identify the initiator of the test. The input parameter **targetNE** identifies the network element to perform self test. The input parameter **timeOutPeriod** identifies the time period that the system will try to initiate the test. The input parameter **specificTestInfo** is used to provide specific self test information providing details on each diagnostic test type to run.
+
+The return value is of type **TestTrackingObjectId** and provides a mechanism to allow the operator to terminate a controlled resource self test. If the resource self test is uncontrolled, the Supplier Management System returns the value 0.
+
+#### 9.15.1.8 terminateResourceSelfTest
+
+This operation terminates a resource self test in progress.
+
+The operation signature for **terminateResourceSelfTest** is shown below:
+
+```
+ResourceSelfTestResultSeqType terminateResourceSelfTest (  
+    in TestTrackingObjectIdType testTrackingObjectId)  
+    raises (UnknownTest, UncontrolledTestInProgress, AccessDenied);
+```
+
+The input parameter **testTrackingObjectId** is used to identify the test to terminate.
+
+The return value of type **ResourceSelfTestResultSeqType** provides whatever interim test results are available.
+

+## 9.16 FileTransfer module
+
+This module deals with the management of non-real time transfer records stored in any short-term archive in the Supplier Management System. It supports the subsequent tracking and monitoring of the file transfer process through the use of TransferTrackingObjectId. The Supplier Management System logs the successful or unsuccessful results of the file transfer. Any request for file transfer is accompanied by security credentials whereby the Supplier Management System is allowed to communicate with the destination server. The file transfer can be scheduled in advance. Transfer Tracking Objects are automatically deleted by the Supplier Management System once the associated file transfer has finished and results (whether successful or unsuccessful) are recorded in the completion log.
+
+### 9.16.1 TransferMgr interface

+    in boolean overwriteExistingFile)  
+    raises (AccessDenied, CommFailure, UnknownRecordSet,  
+    UnknownDestinationServer );
+```
+
+The input parameter **recordSetId** identifies the short-term archive from which the data is to be extracted for file transfer. The input parameter **destinationServerAddr** identifies the data communication networking address for the server that is the destination of the file transfer. The input parameters **userId** and **password** provide the login mechanism to the destination server (assuming such security credentials are needed). The input parameter **destinationFile** provides a full directory location for the transferred file. Finally, the parameter **overwriteExistingFile** indicates whether or not the file transfer should allow the overwriting of a pre-existing file with the same destination directory location.
+
+The return value of type **TransferTrackingObjectIdType** provides a correlation key to be used when attempting to track the status of the non-real time transfer of data from the short-term archive at some later point.
+
+#### 9.16.1.2 **scheduleFileTransfer**
+
+The file transfer is scheduled for future initiation by this operation. All the contents of the identified short-term archive are extracted for file transfer. No assumption is made concerning the purging of the archive based on successful file transfer of data. Instead, the archive is purged, based on agreements between the supplier and operator concerning retention policy of archived information.
+
+The operation signature for **scheduleFileTransfer** is shown below:
+
+```
+TransferTrackingObjectIdType scheduleFileTransfer (  
+    in ManagedEntityIdType recordSetId,

+# 10 Compliance statement
+
+An implementation claiming conformance to any of the interfaces defined in this Recommendation shall implement the complete behaviour associated with all the operations of the interface, as well as behaviour of referenced definitions in the module q834\_4::Q834Common.
+
+# Annex A
+
+## Data dictionary
+
+Table A.1 provides a listing of all data elements (data types) used in the interface specification found within this Recommendation. The listing includes management information interpretation, syntax, and any qualifying comments for each. Data elements are listed in alphabetical order. If a data type and a second data type constructed as a sequence of the first are both present in the interface specification, then only the first data element is defined. The interpretation of the second is obvious. In these cases, the name of the sequence is the name of the original data element with the characters "Seq" inserted before the ending of "Type".

+## Example endpoint templates
+
+Tables D.1 and D.2 provide example templates of how an endpoint might be defined by service type. Table D.1 shows examples for the case when the endpoint is part of an NNI port. Table D.2 shows examples for the case when the endpoint is part of a UNI port.

+# **LINE AND LINE CIRCUIT TEST MANAGEMENT OF ISDN AND ANALOGUE CUSTOMER ACCESSES**
+
+## **Summary**
+
+The purpose of this Recommendation is to define the Q3 interface between a network element for customer access (i.e. local exchange, access network) and the telecommunications management network (TMN) for the support of line and line circuit test functions and the associated management for ISDN and analogue customer accesses which are connected either directly to a local exchange or remotely at an access network and across V5.1 and/or V5.2 interfaces to a local exchange.
+
+The focus of this Recommendation is on defining an object model based on ITU-T Recommendations Q.824.0, Q.824.5, Q.831, and X.745. Existing protocols are used where possible. The definition of Operations System (OS) functionality is outside the scope of this Recommendation.
+
+## **Source**
+
+ITU-T Recommendation Q.835 was prepared by ITU-T Study Group 4 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 26th of March 1999.
+
+### **Keywords**
+
+Access network, information model, line and line circuit testing, local exchange, Q3 interface, TMN.

+## FOREWORD
+
+ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1.
+
+In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.
+
+## NOTE
+
+In this Recommendation the term *recognized operating agency (ROA)* includes any individual, company, corporation or governmental organization that operates a public correspondence service. The terms *Administration*, *ROA* and *public correspondence* are defined in the *Constitution of the ITU (Geneva, 1992)*.
+
+## INTELLECTUAL PROPERTY RIGHTS
+
+The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process.
+
+As of the date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.

+# Introduction
+
+Line and circuit testing of analogue customer accesses and ISDN customer accesses is part of a management activity which is performed by the operator in order to detect failure conditions and to bring the customer access back to its normal state of operation whenever a deviation occurs.
+
+A customer access is considered as being that part of the local network which extends from the network termination equipment up to and including the exchange termination.
+
+Here, only these parts of the activity are covered which are related directly to that part of the customer access which extends from the local exchange to the network termination equipment. An ISDN access extends to but does not include the T reference point. An analogue access extends to and may include the customer premises equipment (CPE) (see Figure 0).
+
+In Figure 0 both customer access scenarios are illustrated:
+
+- Direct access case for PSTN and ISDN customer to a local exchange (LE), which is shown in the top of Figure 0;
+- Remote access case for PSTN and ISDN customer as well as for leased lines (semi-permanent lines) via an access network (AN) and across the V5.1 and/or V5.2 interface (as specified in Recommendations I.414, G.964 and G.965), shown in the bottom part of Figure 0.
+
+The shaded areas are subject to line and circuit testing and the associated management as presented within this Recommendation is based on the specifications within Recommendation Q.831.
+
+![Figure 0/Q.835 – Direct and remote customer access case scenarios. The diagram illustrates two scenarios: direct access and remote access. In the direct access scenario (top), a PSTN TE connects via a Z interface to a PSTN UP at a Local Exchange (LE). An ISDN TE connects via a T interface through an NT1 to an ISDN UP at the same LE. A shaded area covers the TE, NT1, and the interfaces. In the remote access scenario (bottom), a PSTN TE connects via a Z interface to a PSTN UP at an Access Network (AN). An ISDN TE connects via a T interface through an NT1 to an ISDN UP at the AN. A TE connects to an LL UP at the AN. A shaded area covers the TE, NT1, and the interfaces. The AN connects via a V5 interface (V5 TP) to a V5 TP at the Local Exchange (LE). A shaded area covers the AN and the V5 interface. The LE contains the PSTN UP, ISDN UP, and V5 TP. A shaded area covers the AN, the V5 interface, and the LE. The diagram is labeled T0409860-98.](0b87abe67b21a93777287649c33e755d_img.jpg)

+
+NOTE – Shaded areas are subject to line and circuit testing. User ports (UP) represent the different configurations for line circuit, line termination, exchange termination and network termination (NT). The option of ISDN access without remote NT1 is valid for ISDN BA only.

+## Recommendation Q.835
+
+# LINE AND LINE CIRCUIT TEST MANAGEMENT OF ISDN AND ANALOGUE CUSTOMER ACCESSES
+
+(Geneva, 1999)
+
+# 1 Scope
+
+This Recommendation specifies the Q3 interface between a network element for customer access (i.e. local exchange, access network) and the Telecommunications Management Network (TMN) for the support of line and line circuit test functions and the associated management for ISDN and analogue customer accesses which are connected either directly to a local exchange or remotely at an access network and across V5.1 and/or V5.2 interfaces to a local exchange.
+
+It is not mandatory to implement the test and measurements specified in this Recommendation for all types of customer access realisations. However, if any test is implemented and is required to be managed via the Q3 interface on the network element, it shall be modelled as described in this Recommendation.
+
+The focus of this Recommendation is on defining an object model based on Recommendation X.745 [22]. Existing protocols are used where possible. The definition of Operations System (OS) functionality is outside the scope of this Recommendation.

+
+## 4.1 Description of the service
+
+Line and circuit testing is part of a management activity which is performed by the operator in order to detect failure conditions and to bring the customer access back to its normal state of operation whenever a deviation occurs. A customer access is considered as being that part of the local network which extends from the network termination equipment up to and including the exchange termination.
+
+In this clause, only the parts of the activities are covered which are directly related to that part of the customer access which extends from the exchange termination to the network termination equipment. An ISDN access extends to but does not include the T reference point. An analogue access extends to and may include the CPE.
+
+## **4.2 Components of service**
+
+- a) *Failure detection*  
+Observe or supervise the subscriber access and collect relevant data in order to detect failures or degradation. Perform continuous or periodic checks of the system functions.
+- b) *Failure information*  
+Send alarms and event reports from the NE to TMN with failure information related to subscriber access.
+- c) *Failure localization*  
+Receive failure information from NEs which may be generated by performing tests and measurements on subscriber access. Initiate additional fault localization procedures and receive information from these procedures.
+- d) *Fault correction*  
+Replace faulty access port equipment with working replacements.
+- e) *Verification*  
+Apply the appropriate tests and measurements to the replaced component before bringing it back to service.
+- f) *Restoration*  
+Restore the component to service.
+
+## **4.3 Management function list**
+
+- a) *Request status*  
+TMN requests NE to send the current status information related to the access port.
+- b) *Set service state*  
+TMN directs NE to place a access port in a specified service state, e.g. in service (available for use), standby (not for normal use), out of service (unavailable for use).
+- c) *Alarm report*  
+NE notifies TMN of alarm information concerning access ports.
+- d) *Set alarm conditions*

+
+### 5.1.1 Line testing and line circuit testing
+
+Test requests from the OS are sent as Common Management Information Protocol (CMIP) testRequestControlled or testRequestUncontrolled action to an instance of testActionPerformer. In this model, all controlled tests are delegated by instances of testActionPerformer to instances of subclasses of testObject, i.e. when receiving a test request the testActionPerformer automatically creates the required instances of these classes. Further instances of subclasses of testObject are created if further delegation of the performance of the test is required. This creation is achieved by sending additional testRequestControlled actions; the testSessionId parameter is used to identify in which access test instance the new tests should be contained. All instances of these subclasses of testObject exist only for the duration of their delegated operations. Details of the mechanism how to transmit test requests to testActionPerformer and how test results are generated are described in Recommendation X.745 [22].
+
+Management information related to uncontrolled tests can be found in Annex B.
+
+Controlled testing is initially delegated to an instance of `accessTest` or to an instance of `loopTest` or to an instance of `metallicTestAccess`. Each instance of `loopTest` or `accessTest` or `metallicTestAccess` is contained in an instance of `testActionPerformer`.
+
+The object class `loopTest` is used to set up loopbacks for the user port to which it is associated by an attribute. If patterns are to be injected and compared within the NE as part of the loopback test, then this is delegated to an instance of `patternTest` which is contained in the delegating instance of `loopTest`.
+
+The object class `accessTest` has all specific non-loopback tests allocated to it. It has an attribute which specifies one or a list of user ports which are to be tested.
+
+If external test systems are used for line testing, the `metallicTestAccess` allows to connect it to each subscriber line (outbound or bridged) and to each line circuit (inbound) of the NE. The implementation of the metallic test access is outside the scope of this Recommendation.
+
+The creation of an instance of `accessTest` represents a test session and permits test access to lines or line circuits during which a number of different tests can be performed. These delegated tests are handled by specific contained test objects. Each contained test object triggers the specific test on one or more user ports which are specified in `accessTest`.
+
+Electrical measurements, such as voltage, capacitance and resistance, are delegated to instances of `electricalMeasurementTest`. Dialed digit tests, dial tone tests and other tests (in particular those involving sending meter pulses to the line, cable pair identification tone and ringing) are triggered by the creation of instances of `dialedDigitTest`, `dialToneTest`, `spmPulses`, `cablePairIdTone` and `ringing`, respectively. The dry loop condition is set up by instances of `dryLoopTest`. The inward line circuit tests are delegated to instances of `testToLineCircuit`. The `voiceAccessTest` allows for the provision of those tests which involve the establishment of a voice connection with the line under test. A quick check of an ISDN access is represented by an `isdnQuickTest` object.
+
+The object class `testThresholdClass` can be used to modify predefined test thresholds via the Q3 interface.
+
+### **5.1.2 The testResultNotifications of the tests**
+
+The sending time, the information contents and the number of `testResultNotifications` sent per test request are not restricted. It is a matter up to the NE implementation. If the `testResultNotification` contains results whose testing time has importance, they shall be ordered in the ASN.1 sequence oldest first.

+
+**DEFINED AS** "This package provides the central operator with a voice access to the line to be tested. This test shall only be applied to a single User Port. An agent provides the voice path by one or both of the following methods.
+
+For the 'existing connection' method, an object instance with the attribute monitorSpeak set to existingConnection shall enter its initializing phase during an ongoing, previously established normal connection between the User Port and the Operator Port. Then the existing connection shall be transformed into a test condition; i.e. the voice connection shall be maintained (ignoring the testConditions parameter), but the line signalling shall now be controlled by the Q3 interface of the agent by means of other possible test objects for subscriber assisted tests, so that, an on-hook shall not clear the connection at this time, but be indicated to the manager. This allows the use of an existing connection for a subscriber-assisted test.
+
+For the 'parallel voice path' method, the monitorSpeak attribute shall be set to monitorWithoutMark, monitorWithMark or speakAndMonitor. In this method, a parallel voice path across the test function instead of
+
+the User Port line circuit is used. The ringBackNo attribute may be used to inform the test function of the operator's directory number to which the parallel voice path shall be established. If the establishment of the parallel voice path fails, an error shall be reported (ringBackFailed) and the test shall be aborted. After successful establishment of the parallel voice path, the agent shall connect the parallel voice path to the User Port line as requested in the monitorSpeak attribute.

+# 7 Protocol requirements
+
+Protocol suites for the Q3 interface are specified in Recommendations Q.811 [8] and Q.812 [9]. No specific requirements are identified.
+
+# ANNEX A
+
+## Requirements and specification of parameters for access port tests
+
+It is not mandatory to implement test requirements and functionalities described in this Recommendation, but if any test is required to be managed via the Q3 interface on the NE, it shall be modelled as described in the relevant subclause(s) of this Recommendation.
+
+### A.1 General test requirements
+
+These are the general requirements for the test management of access ports via the Q3 interface of an NE.
+
+#### A.1.1 Scheduled testing
+
+The Q3 interface provides the functionality to control scheduling of tests in the NE, if the scheduling functionality is implemented in the NE.
+
+#### A.1.2 Test capability
+
+Information about which tests the NE is able to perform is required at the Q3 interface. The manager should be able to retrieve information about the test capabilities of an NE. If the OS is requesting the execution of a non-existing test, then the NE shall reply with an error message.
+
+### A.2 Access port test requirements
+
+These are the requirements for line and circuit testing of analogue and ISDN subscriber lines managed via the Q3 interface of an NE.
+
+Further complex test procedures may be operator dependant. These procedures may involve the execution of simple tests or other procedures such as subscriber-assisted tests described in this subclause.
+
+#### A.2.1 Access port test management functions
+
+Whenever a test request is sent by the manager to the NE, the following information may be associated to it, as given in Table A.1.
+
+**Table A.1/Q.835 – Possible test request parameters and values**
+
+| Parameter                       | Value                                                                                |
+|---------------------------------|--------------------------------------------------------------------------------------|
+| Type of tests and/or procedures | See list of test requirement description                                             |
+| Scheduling of test              | Start time, stop time                                                                |
+| ID of access ports under test   | List of 1 or N access port object instances involved in the test                     |
+| Type of result                  | Any conceivable combination among three possible results: passed, not passed, values |
+
+If one of the parameters is not permitted in the relevant test request, it shall be ignored by the NE.
+
+If the NE is not able to manage one of the parameters listed above, a notification shall be emitted to the manager indicating the error cause.
+
+#### A.2.2 Test scheduling
+
+The following tests are suitable for scheduled tests:
+
+- foreign voltage and current measurement;
+- capacitance measurement;
+- insulation resistance measurement;
+- all line circuit tests;
+- dial tone test;
+- loopback test;
+- ISDN quick test.
+
+The following requirements are valid for scheduling:
+
+- routine tests shall have lower priority than on-demand test and normal traffic;
+- the test result shall indicate those ports which have not been tested due to any reason;
+
+- it shall be possible to specify the start time and the stop time of the whole test sequence;
+- it shall be possible to specify the test interval between the start of consecutive test sequences (e.g. daily, weekly).
+
+The information model for scheduling and test repetition shall be based on already existing models specified in Recommendation X.746 [23].
+
+#### **A.2.3 Test result management**
+
+The result for a test request shall be reported on a per test and per port basis. These reports are controlled by a combination of the following three Boolean conditions:
+
+- a) pass: if TRUE, send a result report if the port passed the test (the testOutcome field of the additional information parameter of the test result notification in Recommendation X.745 [22] contains the value "pass");
+- b) not passed: if TRUE, send a result report only if the port did not pass the test (in this case the testOutcome field of the additional information parameter of the test result notification in Recommendation X.745 [22] contains one of the following values: "fail", "inconclusive", "timed out" or "premature termination");
+- c) measured values: if TRUE, send the measured values (for these tests producing values as result).
+
+These Boolean values shall be combined by means of the logical operator AND in order to determine when the result is to be sent.
+
+EXAMPLE: When the following combination is used:
+
+```
+pass      = FALSE;
+not passed = TRUE;
+values    = TRUE,
+```
+
+the expected result contains the list of measured values for such ports that have not passed the test.
+
+#### **A.2.4 Test threshold management**
+
+When a passed/not passed result is requested, provisionable threshold values are used, unless the test request contains threshold values which override the provisioned thresholds. After the termination of that test, the provisioned thresholds shall be restored.
+
+Provisionable thresholds are default thresholds for tests which can be modified via the Q3 interface. For each type of test it shall be possible to specify a number of different thresholds. Each of these thresholds shall be assigned to a particular group of thresholds, so-called threshold classes. Access ports may be associated with one of these threshold classes.
+
+#### **A.2.5 Test requirements description**
+
+This subclause deals with requirements for line testing purposes. It is subdivided into PSTN line tests and PSTN inward tests: ISDN BA testing and ISDN PRA testing.
+
+Accuracy and range of measurements are out of the scope of this Recommendation.
+
+##### **A.2.5.1 PSTN line testing**
+
+In general, line testing requires that a certain line condition is established (e.g. off-hook or a line termination); then a test is performed and after the test the line is restored to its normal condition. In some cases, not all of these steps are under the control of the Q3 interface (e.g. where the test action is carried out by craft personnel), and so a test function may include all, or only some, of these steps.
+
+The dry loop test, for example, is concerned only with disconnecting a line from the line circuit. In this case, the actual test conduct and the observation of the test outcome are assumed to be controlled separately.
+
+In the following, "subscriber assisted" and "voice connection" mean that an operator gives instructions to the subscriber on how to perform a test. The subscriber returns the result back to the operator, when applicable.
+
+##### **A.2.5.1.1 Foreign voltage or current**
+
+It is required to check for the presence of foreign voltage or foreign current on the line.
+
+This test is performed by disconnecting the line from the line circuit and measuring foreign voltage or foreign current between a/b, a/E or b/E. Both AC and DC voltage measurement are required. The manager may select one or more of these measurements. Results shall be: passed, not passed and/or the values. Units are V (Volt) or A (Ampere).
+
+###### **A.2.5.1.2 Capacitance measurement**
+
+It is required to measure the capacitance on the line.
+
+This test is performed by disconnecting the line from the line circuit and measuring the capacitance between a/b, a/E or b/E. The manager may select one or more of these measurements. Results shall be: passed, not passed and/or the values. The unit is F (Farad).
+
+##### **A.2.5.1.3 Insulation resistance measurement**
+
+It is required to measure the insulation resistance.
+
+This test is performed by disconnecting the line from the line circuit and measuring the insulation resistance between a/b, a/Earth, b/Earth, aToBattery or bToBattery (both polarities are possible). The manager may select one or more of these measurements. Results shall be: passed, not passed and/or the values. The unit is  $\Omega$  (Ohm).
+
+##### **A.2.5.1.4 Loop resistance measurement**
+
+It is required to measure the loop resistance during off-hook.
+
+The loop resistance between a/b (both polarities are possible) is measured during off-hook. The manager may select one or both measurements. Results shall be: passed, not passed and/or the values. Subscriber assistance may be required. The unit is  $\Omega$  (Ohm).
+
+##### **A.2.5.1.5 Dial pulse test**
+
+It is required to check the proper operation of the subscriber terminal.
+
+The subscriber is requested to dial one or more digits: it is required to verify that the correct sequence of dialled digits is received by the NE. Results shall be: passed, not passed and/or the values. The reported values are number of pulses, average make and break duration.
+
+##### **A.2.5.1.6 DTMF dialling test**
+
+It is required to check the proper operation of the subscriber terminal.
+
+The subscriber is requested to dial one or more digits. It is required to verify that the correct sequence of digits is received by the NE in normal operation. DTMF handling is out of the scope of the V5 interface because the tones are carried transparently through the NE and call processing is performed at the NE. However, an NE implementation may have this test functionality, thus providing a common maintenance support for both types of dialling. Results shall be: passed, not
+
+passed and/or values for dialled digits, tone levels, tone frequencies, pulse length. Units are dBm (decibel relative to 1 milliwatt), Hz (Hertz), s (seconds).
+
+##### **A.2.5.1.7 Subscriber private meter testing**
+
+It is required to check the subscriber's private meter.
+
+The NE sends a specified number of metering pulses to the subscriber. The private meter at the customer premises should then step the same number of pulses. As a result, a comparison is made at the manager between subscriber answer and the notification from the NE about the number of pulses sent. The result parameter is number of pulses.
+
+##### **A.2.5.1.8 Ring subscriber**
+
+It is required to check the proper operation of the subscriber terminal.
+
+The test is carried out by applying the ring signal and checking the answer of the subscriber. When off-hook is detected (both during the ringing tone itself or during the silent interval), no ringing current shall be sent anymore, according to the limits described in Recommendation Q.543 [7]. The digital exchange performance design objectives are:
+
+- a) <100 ms (mean value);
+- b) <150 ms (95% value).
+
+##### **A.2.5.1.9 Monitoring of the line**
+
+It is required that the operator may either listen into the line with or without sending a mark tone, or listen and speak.
+
+###### **A.2.5.1.10 Cable pair identification tone**
+
+It is required to assist the identification of cable pairs in the field, by generating a trace tone at the NE side. The tone shall continue until it is stopped by a manager command or after a timeout.
+
+##### **A.2.5.1.11 Dry loop**
+
+It is required to disconnect the line from the line circuit. This condition is called "dry loop". After a dry loop is established, tests may be performed on the line outside the influence of the Q3 interface, until normal conditions are re-established.
+
+a and b wires are disconnected from the line circuit, leaving them in an open circuit state. The subscriber line shall remain in dry loop condition until re-connected by a manager command or after a timeout.
+
+##### **A.2.5.1.12 Register recall button test**
+
+It is required to check the proper operation of the register recall button of the subscriber terminal.
+
+The subscriber is requested to press the button. The pulse break time is then checked for acceptability. Results shall be passed/not passed.
+
+##### **A.2.5.1.13 Ring back procedure**
+
+The installer at the subscriber site may initiate a test procedure by dialling a special ring back code to the NE. The NE shall then initiate the ring back procedure. If during this procedure line or line circuit tests are required, those already defined in this Recommendation shall be applied. More detailed information on execution of this procedure is contained in Appendix II.
+
+##### **A.2.5.2 PSTN inward tests**
+
+###### **A.2.5.2.1 Line circuit testing**
+
+PSTN line circuit test results shall be reported as passed/not passed covering all circuit tests in a global way, in order to identify the replaceable units.
+
+If the NE is able to provide the relevant information, the manager may be notified about which test failed and the related measured values. Even if the NE supports this information, the management application still requires a pass/fail (passed/not passed) result.
+
+In the following, detailed requirements are described. This list is not exhaustive, and new items may be added in the future.
+
+Thresholds for result comparison are specific to the line card implementation and the manager is not required to manage (both reading and setting) them.
+
+###### **A.2.5.2.1.1 Feeding voltage**
+
+Feeding voltage between a and b wires shall be measured.
+
+###### **A.2.5.2.1.2 Feeding current**
+
+Feeding current between a and b wires shall be measured.
+
+###### **A.2.5.2.1.3 Loop and ring trip detection**
+
+It is checked whether the line circuit is able to detect a loop (i.e. an off-hook) with both normal and reversed polarity, while the line circuit is busy or idle (busy means ongoing call on the line). The ring trip detection is carried out by applying the ring signal and simulating the answer of the subscriber. When off-hook simulation is detected (during the ringing tone itself or during the silent interval), the ringing current shall be stopped immediately, according to the limits described in Recommendation Q.543 [7]:
+
+- a) <100 ms (mean value);
+- b) <150 ms (95% value).
+
+###### **A.2.5.2.1.4 Ringing current sending**
+
+The ringing current shall be measured at the line side of the line circuit.
+
+###### **A.2.5.2.1.5 Private meter pulses**
+
+The duration and the level of private meter pulses shall be tested.
+
+###### **A.2.5.2.1.6 Codec testing**
+
+The analogue-to-digital and the digital-to-analogue conversion shall be tested including hybrid functionality.
+
+###### **A.2.5.2.1.7 Digit reception**
+
+The line circuit is tested to check whether it receives a hexadecimal digit. The test shall be performed with both normal and reversal polarities.
+
+##### **A.2.5.2.2 Other inward tests**
+
+###### **A.2.5.2.2.1 Dial tone test**
+
+An off-hook condition is simulated in the NE. It shall be checked whether the dial tone appears at the LC termination or not.
+
+##### **A.2.5.3 ISDN BA testing**
+
+###### **A.2.5.3.1 ISDN BA line testing**
+
+If copper wires are used, the following line tests as defined for PSTN lines shall be carried out:
+
+- foreign voltage;
+- current measurement;
+- capacitance measurement;
+- insulation resistance measurement (only normal polarity is possible);
+- dry loop.
+
+###### **A.2.5.3.2 ISDN BA line termination testing**
+
+###### **A.2.5.3.2.1 Loopbacks**
+
+Generally, a loopback is set up to test the integrity of the devices and the line between two points, by applying a known signal (pattern) on one side and checking whether the signal received is the same as the sent one. The input signal may be applied either by a device embedded in the network element which contains the port (or related line) under test, or by an external equipment. In the latter case, it is required that a loopback is set up without signal generation.
+
+According to Recommendation M.3603 [5], the terminology for ISDN BA loopbacks is:
+
+- loopback 1: complete Line Termination (LT) loopback;
+- loopback 1A: Regenerator (REG) loopback;
+- loopback 2: complete NT1 loopback;
+- loopback 2<sub>1</sub>: B1, B2, NT1 loopback.
+
+The NT1 may be located either within or outside the NE (see Figure 1).
+
+All the loopbacks mentioned above may be applied in connection with either an NE internal equipment or an external equipment to inject and detect a test pattern. The line under test is activated and a loopback is established.
+
+The manager shall be notified whether the loopback is set up or not.
+
+If the pattern injection and detection equipment are under the control of the manager via the Q3 interface, pattern injection and detection shall be initiated after the set-up of the loopback. The pattern may be injected at a particular point and detected either at the same point or at another one. The received pattern shall be compared with the sent one and the result shall be: passed, not passed and/or bit error rate.
+
+###### **A.2.5.3.2.2 Activation and deactivation of lines**
+
+It is required to check the capability for activating and deactivating the line under test.
+
+##### **A.2.5.3.3 ISDN BA line circuit testing**
+
+###### **A.2.5.3.3.1 Power feed**
+
+It is required to measure the feeding voltage between a and b wires provided by the line circuit. The voltage between a and b shall be measured in order to verify the proper operation of the power feeding of the NT1. The reported result shall be: passed/not passed.
+
+##### **A.2.5.4 ISDN PRA testing**
+
+##### **A.2.5.4.1 ISDN PRA line testing**
+
+Not applicable.
+
+##### **A.2.5.4.2 ISDN PRA line termination testing**
+
+Set-up of loopbacks at the LT (loopback 1) at the regenerator [if more than one regenerator is installed, it shall be the one which is closest to the line termination (loopback 1A)] and at the NT1 (loopback 2) shall be possible.
+
+According to Recommendation M.3604 [6], the terminology for ISDN PRA loopbacks is:
+
+- loopback 1: complete Line Termination (LT) loopback;
+- loopback 1A: Regenerator (REG) loopback;
+- loopback 2: complete NT1 loopback.
+
+##### **A.2.5.5 ISDN BA and PRA quick tests**
+
+In order to perform a quick test of the basic functionality of an ISDN BA or PRA, it shall be possible to apply a certain set of tests on the ISDN line. This includes the following tests:
+
+- layer 1 activation (in case of an ISDN BA: test on the capability to activate the layer 1; in case of an ISDN PRA: test on the presence of an active layer 1);
+- loopback test;
+- power feeding test;
+- function test.
+
+If the ISDN quick test function is implemented in the NE, it shall be possible to invoke this quick test via the Q3 interface.
+
+##### **A.2.5.6 Connection of external test systems**
+
+For external test systems used for line testing, a metallic test access shall be provided to each subscriber line (outbound) and to each line circuit (inbound) of the NE. It shall be possible to connect the test system to the outbound or inbound line and to disconnect it via the Q3 interface of the NE.

+# ANNEX C
+
+## Test termination
+
+As specified in Recommendation X.745 [22], a test may terminate spontaneously or by request. In the following subclauses, guidelines are given on termination of line and circuit tests.
+
+### C.1 Termination of uncontrolled tests
+
+Uncontrolled tests terminate spontaneously:
+
+- upon completion of the test; or
+- upon fault situations; or
+- upon the fulfilment of predefined criteria.
+
+These predefined criteria and some specific fault situations are specified by the test category. The final test results or test failure response shall be returned using the test request uncontrolled action response message.
+
+### **C.2 Termination of controlled tests**
+
+Controlled tests shall terminate depending on the test invocation:
+
+#### **C.2.1 One-step test**
+
+A one-step test is specified by one or more tests being invoked by a single test request controlled action. The request specifies a new access test object together with the test object(s) representing the specific test(s) to be performed.
+
+A one-step test shall terminate spontaneously:
+
+- upon completion of the test; or
+- upon fault situations; or
+- upon the fulfilment of predefined criteria.
+
+These predefined criteria and some specific fault situations shall be specified by the test category or TO class. The final test results shall be returned using one or more controlled test result notifications. A test failure response shall be returned in the test request controlled action response or be contained in result notifications.
+
+Before completion of the requested tests, a one-step test may be terminated by a test terminate action directed to the test action performer which received the test request. The tests are identified in termination requests using the test invocation id. All TO(s) identified by the test shall be terminated; otherwise, an error shall be returned. The tests that have been terminated successfully as a result of this termination request shall be returned in the action response. In case an error occurs during test termination, the agent shall respond with a test termination error.
+
+#### **C.2.2 Test session**
+
+A test session is invoked by a test request controlled action which specifies a new access test object without any contained specific test objects. Subsequently, one or more other test requests are given which specify the specific tests to be performed within the already existing test session.
+
+Test sessions shall be terminated by a test terminate action directed to the test action performer which received the test request. Test sessions may terminate spontaneously in case of fault situations or due to a time out specified in the test request. In case specific tests represented by contained test objects are invoked for this test session, these tests shall also be terminated. Test sessions are identified in termination requests using the test session id or the corresponding list of test invocation id(s). If a test session id is provided in the termination request, test invocations identified by the session shall be terminated in a best effort fashion. If a test invocation id is provided in the termination request, all TO(s) identified by the test shall be terminated; otherwise, an error shall be returned. In the response to the termination request, the list of all test invocations that have been terminated as a result of this request shall be returned.
+
+Specific controlled tests invoked during a test session shall terminate spontaneously or may be terminated by a test terminate action before completion of the test. Requirements are the same as for one-step tests.
+
+#### **C.2.3 Aborting tests**
+
+Controlled tests may also be aborted by deleting all TO(s) related by the same test invocation identifier. Test objects accepting deletion requests shall not emit any further test result reports. Where available it is recommended that the Scope parameter include all TOs with the same Test invocation identifier and that the Filter parameter select TOs with the same Test invocation identifier. If an abort request results in the deletion of some, but not all, TOs with the same test invocation identifier, the test becomes indeterminate. In this case, it is recommended to terminate the
+
+test by subsequent attempts to delete the surviving test objects. Yet, it may depend on the specific implementation how to resolve this situation.
+
+#### **C.2.4 Termination sequence**
+
+When a controlled test or test session is terminated, the TO(s) of the test or test session will execute a termination sequence which may include issuing test result reports and performing any necessary clean-up including ending the test activity of MORT(s) and associated object(s). Successfully terminating a test or a test session implies that all the TO(s) of the test or test session are deleted automatically. If a result report is issued and the test outcome has not been concluded, then the test outcome shall indicate a value of premature termination. The temporal order in which the termination sequence(s) are carried out is system specific and not defined by the test.
+
+# **ANNEX D**
+
+## **Test result notification**
+
+As specified in Recommendation X.745 [22], test results of controlled tests may be emitted as notifications from the TO. The results are provided by one or more notifications.
+
+- 1) A result notification shall contain the test invocation identifier of the test.
+- 2) If present in the test request, the test session identifier and the associated object identifier shall also be present in the result notification. They may be used for the correlation of test results.
+- 3) The additional information identifier shall be present in the notification if specified in the behaviour of a specific test.
+- 4) The MORTs identifier shall be present if not included in the test-specific additional information field.
+- 5) The test outcome parameter shall be included in the result notification to indicate the completion of a test. In case a TO is sending more than one test result notification during the execution of a test, then the test outcome parameter also indicates that the TO is sending no more reports for the execution of the test. The parameter shall not be included in intermediate result notifications. It may take one of the following values: pass, fail, inconclusive, timed-out or premature termination, indicating the overall outcome of the test. In addition, notifications may contain specific test outcome information pertinent to the type of test.
+
+The use of further generic information of the test result notification is left up to the implementation.
+
+# ANNEX E
+
+## Additional requirements on the test action performer
+
+This annex contains additional requirements on the implementation of the test action performer which detail the generic capabilities specified in Recommendation X.745 [22].
+
+### E.1 Indication of supported tests
+
+It shall be possible to retrieve the line and circuit test capabilities of an agent system. For this purpose the testActionPerformer object class specified in Recommendation X.745 [22] shall support the following packages:
+
+- supportedTOClassesPackage, if controlled tests are supported; and
+- supportedUncontrolledTestsPackage, if uncontrolled tests are supported.
+
+Supported controlled tests are identified by a set of object identifiers of their related TO classes. Supported uncontrolled tests are identified by a set of object identifiers of their respective uncontrolled request parameter.
+
+On receipt of a test request indicating a controlled test not supported by the agent system, an independent or related test invocation error shall be generated. On receipt of a test request indicating a not supported uncontrolled test, a mistyped test category information error shall be generated in the agent system.
+
+### E.2 Indication of unsuccessful test requests
+
+The response to a not successful line or circuit test request shall contain a failure indication and information pertaining to the failure. According to Recommendation X.745 [22], these failures shall be reported as Specific Errors.
+
+# ANNEX F
+
+## Requirements and specification of parameters for V5 interface tests
+
+### F.1 V5 interface test requirements
+
+These are the requirements for the test management of V5 interfaces via the Q3 interface at either side of a V5 interface. They are covered by the information model defined in this Recommendation.
+
+#### F.1.1 V5 interface ID testing
+
+The testing of consistency between the V5 interface IDs at either side of a V5 interface is required.
+
+#### F.1.2 Link ID testing
+
+The testing of consistency between the link IDs at either side of a V5 2048 kbit/s link is required.
+
+#### F.1.3 Provisioning variant testing
+
+The testing of consistency between the provisioning variant labels at either side of a V5 interface is required.

+## Description of test procedures – Application for V5 access networks
+
+## II.1 Background
+
+This appendix describes complex test procedures, as ringback service and all subscriber-assisted tests at the AN side, to show the impact that they have on both Q3 interfaces.
+
+## II.2 Test procedures scenario
+
+The general scenario (Figure II.1) includes four functional blocks and all reference points between them as described in Recommendation M.3010 [3].
+
+The functional blocks are: NE functionalities which represent LE and AN, and OS functionalities managing AN and LE.
+
+The reference points are: q (between AN or LE and respective OS) and q (or x if they belong to different TMNs) between OSs<sup>1</sup>.
+
+<sup>1</sup> This reference point and the interface relating to it are out of the scope of this Recommendation.

+
+### II.2.1 Scenario for faultsman ringback tests in an AN environment
+
+Figure II.2 gives a synopsis of all elements involved in maintenance of an AN subscriber line and set: in this example, all the previous reference points have been translated to interfaces and the OSs belong to different TMNs. The telephone set located at the AN operator premises will not be used for this scenario as the operator at the subscriber location will only get responses from the system:
+
+- 1) The operator at the subscriber location (installer) dials a special service code. This special code is detected at the LE over the V5 interface (③ in Figure II.2):
+  - a) the LE notifies the OS<sub>LE</sub> via the Q3<sub>LE</sub> interface (⑤ in Figure II.2);
+  - b) the OS<sub>LE</sub> "informs" OS<sub>AN</sub> via the X interface (⑥ in Figure II.2);
+  - c) OS<sub>AN</sub> checks via Q3<sub>AN</sub> if Test Equipment is available at AN level and reserves this equipment (④ in Figure II.2).
+  - d) reporting back from OS<sub>AN</sub> to OS<sub>LE</sub> via X interface (⑥ in Figure II.2).
+  - e) OS<sub>LE</sub> initiates tone LE via Q3<sub>LE</sub> (⑤ in Figure II.2).
+- 2) If test equipment is available, the LE answers with a ringing tone (③ in Figure II.2), otherwise with a busy tone (③ in Figure II.2).
+- 3) The installer puts the set on-hook (③ in Figure II.2):
+  - a) the LE notifies the OS<sub>LE</sub> via the Q3<sub>LE</sub> interface of the on-hook (⑤ in Figure II.2);
+  - b) the OS<sub>LE</sub> "informs" OS<sub>AN</sub> via the X interface (⑥ in Figure II.2);
+  - c) OS<sub>AN</sub> requests testing at AN level via Q3<sub>AN</sub> (④ in Figure II.2);
+  - d) the AN blocks the related user port object instance via the V5 protocol (③ in Figure II.2).
+- 4) Automatic testing is performed by the AN (foreign voltage, insulation, capacitance, etc.):
+  - a) the AN notifies the test results via Q3<sub>AN</sub> to OS<sub>AN</sub> (④ in Figure II.2);
+  - b) the test equipment is disconnected at the AN;
+  - c) reporting back the passed/not passed result from OS<sub>AN</sub> to OS<sub>LE</sub> via X interface (⑥ in Figure II.2);
+  - d) OS<sub>LE</sub> initiates ringing to LE via Q3<sub>LE</sub> (⑤ in Figure II.2) and indicates which tone to apply.
+
+- 5) The LE rings the installer back.
+- 6) The installer takes the set off-hook (implying the ringer is OK).
+- 7) The test results (of item 4 above) are communicated with a tone (passed: dial tone, not passed: busy tone) to the installer (③ in Figure II.2).
+- 8) Faultsman receives dial tone and sends digits (DTMF or DECADIC) in a given order, removal of dial tone after first digit (③ in Figure II.2). This is just a check of the capability to dial (i.e. no measurements are performed on the dial performance).
+- 9) Passed/not passed tone to report a successful test (③ in Figure II.2).
+- 10) End of test, set on-hook:
+  - a) the LE notifies the OS<sub>LE</sub> via the Q3<sub>LE</sub> interface of the on-hook and successful test (⑤ in Figure II.2);
+  - b) the OS<sub>LE</sub> "informs" OS<sub>AN</sub> via the X interface (⑥ in Figure II.2);
+  - c) report is printed on the AN operator printer (⑦ in Figure II.2).

+
+The diagram illustrates the physical architecture for faultsman ringback service and subscriber-assisted tests in an AN environment. It shows the following components and connections:

+
+### II.2.2 Scenario for a subscriber-assisted test in an AN environment
+
+The subscriber-assisted tests, i.e. those in which the subscriber at its premises handles the telephone set and observes the SPM, are normally carried out with a speech connection between him and the operator who is also working at the OS<sub>AN</sub>. This speech connection can be in two modes, as specified in the voice access package.
+
+#### II.2.2.1 Existing connection mode
+
+- 1) A normal connection is set up between the subscriber and the operator. This connection can be, for example, due to a claiming call from the subscriber (①-③-② in Figure II.2) (no charging should be applied) or may be originated by the operator (②-③-① in Figure II.2).  
+The operator indicates to the subscriber that some tests are going to be performed, and requests assistance for this purpose according to the following instructions.
+- 2) The operator, by means of a test request on the Q3<sub>AN</sub> interface (⑦-④ in Figure II.2), converts the existing voice connection into a test connection (by creating an access test object and a voice access test object contained in it with the monitorSpeak parameter set to existingConnection). The test connection condition means that the voice connection is kept (①-③-②) but the line signalling is put under the control of the OS<sub>AN</sub> interface instead of the LE, which will not receive any V5 signal message.
+- 3) If, for example, the ringing function of the telephone set has to be tested, the operator asks the subscriber to hang up and to pick up again when the set rings (or after a given time otherwise). The on-hook is noticed by the operator by listening to the line (or by previously creating within the access test object a dialled digit test object which reports the on-hook signal event through the Q3<sub>AN</sub> interface).  
+Then the operator creates within the access test object a ringing test object. This causes the AN to generate ringing to the subscriber's line. The test object will generate a result either upon the off-hook detection or when a built-in timer expires (e.g. a little before the subscriber should pick up if the ringing does not work). In both cases the ringing test object is automatically deleted.
+- 4) If, for example, the dialling function of the telephone set has to be tested, the operator creates within the access test object a dialled digit test object and then asks the subscriber to dial a given sequence of digits. Information on detected digits at the AN and their performance (e.g. make/break duration) are reported by the test object to the OS<sub>AN</sub> where the operator checks it. The dialled digit test object is automatically deleted.
+- 5) If, for example, the SPM pulse reception function has to be tested, the operator asks the subscriber to watch how many pulses are going to be received, then creates within the access test an SPM pulse test object with the desired number of pulses to be sent as a parameter. This causes the generation of those pulses. The subscriber counts the number of pulses accumulated in the SPM and it is checked against the generated number.
+- 6) When no more subscriber-assisted testing is needed, the operator terminates the voice access test object and the access test object through the Q3<sub>AN</sub> interface. An implementation may restore the original normal connection condition (voice connection kept and line signalling again under LE control) or release the connection completely.
+
+#### II.2.2.2 Parallel voice path mode
+
+- 1) The operator creates through the Q3<sub>AN</sub> interface (⑦-④ in Figure II.2) an access test object and contained in it a voice access test object with the monitorSpeak parameter set to speakAndMonitor. This causes the AN to block the port (③ in Figure II.2) and to generate a call from the AN-internal test function (simulating to be a telephone) to the telephone number of the operator, provided in the ringBackNo parameter of the test request (③-② in Figure II.2, though the V5 interface and the LE for the test function may not be the same as for the port to be tested).
+- 2) Once the voice path between the operator and the test function is established, the test function is connected to the subscriber's line so that the operator and the subscriber can speak to each other.
+
+3), 4) and 5) as in the existing connection mode above.
+
+- 6) When no more subscriber-assisted testing is needed, the operator terminates the voice access test object and the access test object through the Q3<sub>AN</sub> interface. The user port is unblocked (③ in Figure II.2) and gets ready for normal traffic.

+
+## State management in relation with line testing – Application for V5 access networks
+
+## III.1 Intrusive tests
+
+Tests can be intrusive or non-intrusive. A test on a resource is intrusive when its testing phase is incompatible with the normal working of that resource.
+
+Most of the test functionality modelled in this Recommendation is intrusive, the only exceptions being that of the monitoring function and of the monitor-and-speak function while a previous connection between the user port being tested and a third party is still on (if this connection is cleared, then the monitor-and-speak function becomes intrusive).
+
+Additionally, any tests performed during a speech connection between the operator and the user in the "existingConnection" mode (as described in the voiceAccessTest object) are not considered as intrusive.
+
+## III.2 Dealing with conflicts between intrusive tests and normal service
+
+When a resource is disabled for any reason, it cannot provide its normal service and thus there is no conflict with intrusive tests. For V5-related user ports, the disabled state of the object implies the blocked state of the corresponding V5 FSM. Disabling reasons are AN-internal, e.g. faults or a (V5-specific) blocking procedure initiated at the LE, as specified in Recommendation Q.824.5 [11].
+
+When a resource is not disabled, a way of avoiding conflicts between intrusive testing on that resource and its normal working is by preventing the latter by setting its administrative state to "locked" (via shutting down, if desired). This state also allows the holding of a test session without risk of interruption due to call attempts between consecutive tests. With V5-related user ports, the locked state implies that the V5 FSM is blocked (see Recommendation Q.824.5 [11]).
+
+However, the locking or shutting down and the subsequent unlocking operations on the Q3 interface may be cumbersome, e.g. in the case of series of single tests on many user ports, and for this reason the model allows to avoid them. In this case, the AN shall solve interferences between an intrusive test and normal traffic according to the priority criterion defined in the testConditions parameter of the request for the containing access test. As specified in the object model, tests to be initiated when the port is not idle may have to be rejected ("reject if busy"), or wait until the port becomes idle ("wait if busy", with a time limit set by the waitTime parameter), or force the clearance of the call ("test if busy").
+
+NOTE 1 – A test session without call interruptions between tests can be supported, without using the locked administrative state, by means of the access test object along with the testSessionId parameter.
+
+NOTE 2 – The above approach of using the administrative state does not cover the "reject if busy" case or the timing facility for the "wait if busy" case.
+
+In order for the AN to appropriately use the testConditions and the waitTime parameters, two functions are necessary:
+
+- 1) capability to know whether there is an ongoing call;
+- 2) procedures for the possible cases of interference.
+
+Regarding function 1, the general principles for ANs and in particular the V5 specifications state that the AN has limited or no knowledge of the state of the call. On that basis, there are two ways out:
+
+- a) for V5-related user ports, an approach is the use of the V5 blocking mechanisms. They only indirectly provide some call information, but at the same time cover function 2 (they are active procedures), as explained in III.4;
+- b) it is possible for an AN to have additional capabilities allowing it to get call state information, if an implementation goes beyond the definition of AN in the V5 specification.
+
+This approach has the disadvantage of making the AN more complex and dependent on possibly network-specific and time-evolving signalling issues, against the spirit of the V5 specification. However, it cannot be ruled out, and for that reason the V5 blocking approach described below is not in the normative part of this Recommendation. Moreover, keeping independence on the V5 specificities allows the model to be used in non-V5 environments.
+
+Regarding function 2, in the case of a user port related to a V5 interface, the normal way is by means of the V5 blocking mechanisms, even if a different approach is used for function 1.
+
+A second aspect of possible interference between service and testing is when a call attempt occurs during the execution of a test. The testConditions parameter may also be used by the manager to choose which function prevails, as described in the model. The "customer overrides" option, which is not possible if the locked administrative state is used, requires the AN to be able to detect the call attempt, as well as procedures to abort the test, and for this aspect the same considerations above are valid.
+
+## **III.3 State values during intrusive testing**
+
+Whenever the user port is in the testing phase of an intrusive test, it cannot give normal service. Thus, the testing phase of an intrusive test is an AN-internal disabling reason, i.e. one of the possible reasons for its disabled operational state.
+
+For short tests, this general rule may be simplified so that the Q3 interface state attributes of the user port are not affected, thus avoiding the corresponding notifications and manager processing. This means that during the test execution the disabled condition of the port is only known by the AN.
+
+For V5-related user ports, the disabled condition (even if not reflected on the Q3 interface) means the blocked state of the V5 FSM, as defined in Recommendation Q.824.5 [11]. Exceptions are or may be:
+
+- the dial tone test requires the unblocked state due to its special nature;
+- for other tests, if their execution have a very short duration, an implementation might not follow this rule.
+
+## **III.4 V5 blocking mechanism**
+
+This subclause describes the use of the V5 blocking mechanism for V5-related user ports to cover functions 1 and 2 (as described in III.2) as a complement of the generic behaviour description of the test environment conditions package.
+
+- If the testConditions parameter is set to "test if busy", the V5 urgent blocking procedure is started so that the test proceeds (as far as this mechanism is concerned, the AN does not know if there was a call).
+- If the parameter is set to "wait if busy", the V5 deferred blocking is started, and it is up to the LE to block the port (when this happens, the AN "knows" that the call has finished). If the timer expires, the AN cancels the block request.
+
+- The least elegant case for this approach is when the testConditions parameter is set to "reject if busy", as there is no direct V5 mechanism. Then the AN starts the deferred blocking procedure; if after "a few seconds" the LE has not yet confirmed the blocking, the AN assumes that there is a call and rejects the test, while the block request to the LE is cancelled.
+
+For the dial tone test, these procedures need to be complemented, once the port is blocked, by the unblocking procedure (if the concept of test session were to be supported to avoid a call to interrupt a sequence of dial tone tests, the user port would be immediately blocked after each test).
+
+It is possible for an implementation to follow the above V5 blocking approach with the variation that, for PSTN ports and/or ISDN-BA ports without permanent line activation, the AN determines by itself whether the line is busy, only in order to simplify the "reject if busy" case (direct rejection if the port is found busy); and, on PSTN ports, also to simplify the dial tone test (direct testing when the port is found idle).

+## FOREWORD
+
+The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993).
+
+ITU-T Recommendation Q.86, clause 7 was revised by ITU-T Study Group 11 (1993-1996) and was approved under the WTSC Resolution No. 1 procedure on the 17th of October 1995.
+
+## --- NOTE
+
+In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+## **SUMMARY**
+
+This Recommendation provides the stage 2 service description of the International Telecommunication Charge Card supplementary service. This Recommendation describes the validation of the charge card in terms of the transfer of the necessary validation information to the card issuing administration across an international interface.
+
+## STAGE 2 DESCRIPTION FOR CHARGING SUPPLEMENTARY SERVICES
+
+(revised 1995)
+
+## 7 International Telecommunication Charge Card (ITEC)
+
+## 7.1 Scope
+
+This Recommendation provides a stage 2 description for the International Telecommunication Charge Card (ITCC) as defined in Recommendations E.113 and E.118. The ITCC service provides for the validation of the charge card and transmission of call documentation to the card issuing Administration across the international interface (SCF-SDF). Other interfaces associated with placing an international charge card call that are beyond the international validation (e.g. collecting information and user prompting performed by SRF) are national in nature and therefore beyond the scope of this Recommendation.

+## 7.3 Definitions
+
+For the purposes of this Recommendation, the following definitions apply.
+
+**7.3.1 card acceptor** (Subclause 3.2/E.116): The Recognized Operating Agency (ROA) that accepts the use of the card as payment for the provision of certain telecommunication services.
+
+**7.3.2 card acceptor SDF**: It is the SDF (Service Data Functions) of the card acceptor where the service agreements are stored. It is designated SDF(ca).
+
+**7.3.3 card issuer**: (Subclause 3.1/E.116) The Recognized Operating Agency (ROA) that issues the card. The card issuer is responsible for the collection of charges from the card holder and for making the appropriate payments for the service concerned to the card acceptor.
+
+**7.3.4 card issuer SDF**: It is the SDF of the card issuer where the ITCC charge card user profile is stored. It is designated SDF(ci).
+
+**7.3.5 originating network**: The network from which any user originates an ITCC service request.
+
+**7.3.6 personal identification number** (Subclause 2.2.6/E.113): The Personal Identification Number (PIN) is used by the card issuer to identify the user and authorize the use of the card. It is obtained from the user or encoded on the card.
+
+**7.3.7 primary account number** (Subclauses 2.2.3/E.113 and 2.1/E.118): The Primary Account Number (PAN) (19 visible characters – maximum) is the number assigned to a charge card. It is obtained from the card or the user when the user attempts to make a charge card call. The user identification number, which is a subpart of the Primary Account Number, can be used by the call originating ROA to identify the card-issuing ROA.
+
+**7.3.8 terminating network**: It is the network of the called party.

+## 7.5 Description of ITCC
+
+The International Telecommunication Charge Card service allows the holder of a telecommunication charge card to make use of a variety of telecommunication services provided by the card acceptor and have the charges billed to the customer's account by the card issuer (see Recommendations E.113, E.116 and E.118).
+
+## 7.6 Functional model for ITCC
+
+### 7.6.1 Functional model description
+
+This subclause contains a description of the functional model of ITCC and it is depicted in Figure 1. The functional model merges the IN and non-IN models as defined in the reviewed Recommendation Q.65. It contains nine Functional Entities (FE1 to FE9) and seven relationship types (Rj, Rm, Rn, Rp, Rq, Rs and Rr). Functional Entities are represented by circles and the relationship between two communicating functional entities is identified by a line joining them. Modelling of entities and information flows which relate to the service management are not shown.
+
+There are three networks involved in the validation procedure. They are originating, terminating and card issuing.

+Functional model for ITCC provision
+
+In Figure 1 the Functional Entities (FEs) have the following meaning:
+
+- FE1: Originating Call Control Agent Function (CCAF).
+- FE2: Originating Call Control Function (CCF) associated with Service Switching Function (SSF).
+- FE3: Not used.
+- FE4: Terminating CCF.
+- FE5: Terminating CCAF.
+- FE6: Service Control Function (SCF).
+- FE7: Service Data Function in the Originating network [SDF(ca)].
+- FE8: Specialized Resource Function (SRF).
+- FE9: Service Data Function in the Terminating network [SDF(ci)].
+
+NOTE – In CS-1, the CCF and SSF are assumed to have a relationship which is not externally visible and which is therefore not subject for standardization.
+
+It can be assumed that descriptions of FEs for non-IN is similar to an IN description.
+
+With reference to 3.3/Q.1214, a description of these FEs is given below:
+
+#### **The CCA Function (CCAF)**
+
+The CCAF is the Call Control Agent (CCA) Function that provides access for users. It is the interface between user and network Call Control functions. It:
+
+- a) provides for user access, interacting with the user to establish, maintain, modify and release, as required, a call or instance of service;
+- b) accesses the service-providing capabilities of the Call Control Function (CCF), using service requests (e.g. set-up, transfer, hold, etc.) for the establishment, manipulation and release of a call or instance of service;
+- c) receives indications relating to the call or service from the CCF and relays them to the user as required;
+- d) maintains call/service state information as perceived by this functional entity.
+
+#### **The CC Function (CCF)**
+
+The CCF is the Call Control (CC) Function in the network that provides call/connection processing and control. It:
+
+- a) establishes, manipulates and releases call/connection as “requested” by the CCAF;
+- b) provides the capability to associate and relate CCAF functional entities that are involved in a particular call and/or connection instance (that may be due to SSF requests);
+- c) manages the relationship between CCAF functional entities involved in a call (e.g. supervises the overall perspective of the call and/or connection instance);
+- d) provides trigger mechanisms to access IN functionality (e.g. passes events to the SSF).
+
+#### **The SS Function (SSF)**
+
+The SSF is the Service Switching (SS) Function, which associated with the CCF, provides the set of functions required for interaction between the CCF and a Service Control Function (SCF). It:
+
+- a) extends the logic of the CCF to include recognition of the service (service control triggers) and to interact with the SCF;
+- b) manages signalling between the CCF and the SCF;
+- c) modifies call/connection processing functions (in the CCF) as required to process requests for IN and non-IN provided service usage under the control of the SCF.
+
+#### **The SC Function (SCF)**
+
+The SCF is a function that commands call control functions in the processing of IN provided and/or custom service requests. The SCF may interact with other functional entities to access additional logic or to obtain information (service or user data) required to process a call/service logic instance. It:
+
+- a) interfaces and interacts with Service Switching Function/Call Control Function, Specialized Resource Function (SRF) and Service Data Function (SDF) functional entities;
+- b) contains the logic and processing capability required to handle IN-provided service attempts.
+
+#### **The SD Function (SDF)**
+
+The SDF contains customer and network data for real time access by the SCF in the execution of an IN provided service. It interfaces and interacts with SCFs as required.
+
+NOTE – The SDF contains data relating directly to the provision or operation of IN provided services. Thus it does not necessarily encompass data provided by third party such as credit information, but may provide access to these data.
+
+#### **The SR Function (SRF)**
+
+The SRF provides the specialized resources required for the execution of IN and non-IN provided services (e.g. digit receivers, announcements, conference bridges, etc.). It:
+
+- a) interfaces and interacts with SCF and SSF (and with the CCF);
+- b) may contain the logic and processing capability to receive/send and convert information received from users;
+- c) may contain functionality similar to the CCF to manage bearer connections to the specialized resources.
+
+For the purposes of this Recommendation, the CCAF is identical with the CCA of Recommendation Q.71. The CCF is based on the corresponding Q.71 ISDN definitions but modified for the use in IN. The enhanced Basic Call Model of IN defines standard Detection Points (DPs) at which IN service feature logic instances can be invoked. These DPs correspond to the Q.71 “hooks” where an ISDN supplementary service interfaces to the Basic Call Model. For the purposes of this Recommendation, relationships R<sub>j</sub>, R<sub>n</sub>, R<sub>m</sub> are outside the scope of this Recommendation and are identical with those defined in Recommendation Q.71. For the purposes of this Recommendation, R<sub>s</sub> is identical with relationship r<sub>2</sub> in Recommendation Q.71, since it involves the control of a connection between CCF and SRF in order to provide specialized resources such as tones and announcements. Network capabilities common to a number of supplementary services for user interaction and their switching and signalling requirements are also outside the scope of this Recommendation. Finally, as the R<sub>p</sub> and R<sub>r</sub> relationships are nationally dependent, only the relation R<sub>q</sub> is in the scope of this Recommendation.
+
+This Recommendation treats the case where there is no transfer of the user’s service profile information and SDF(ci) will be accessed for any query (e.g. validation request) on or update (e.g. threshold update) of the ITCC user’s data. Note that the SDF(ci) does not belong to the card acceptor and it is usually located outside the national boundary.
+
+The SDF associated with the card acceptor network may contain some data related to the provision of ITCC service to the visiting user. For example, SDF(ca) may contain information on agreements with other ITCC service providers. No additional security for interworking is provided other than such knowledge of existence of service agreements between service providers. SDF(ca) may also contain data on security measures, e.g. the number of retries allowed by the originating network to an ITCC user attempting to access ITCC service. It is also assumed that SDF(ci) will also be able to check that a service agreement exists with the service provider of the invoking SCF.
+
+## 7.7 Information Flows for ITCC
+
+The Information Flows (IFs) and their contents (Information Elements, IEs) are based on those developed by Study Group 11 for the IN architecture, as described in clause 6/Q.1214. The individual IFs are described in 7.7.2 of this Recommendation. Whether IFs are confirmed or unconfirmed and of type req. ind. or resp. conf. is described here. Information flows and information elements for non-IN can be considered to be equivalent.
+
+In the information flow diagrams the CS-1 IF names are shown in mixed case lettering, without the req. ind. or resp. conf. descriptors. The full descriptions of these IFs are in 7.7.2 (The individual IFs). IFs derived from Recommendation Q.71 are shown in upper case italic letters, with type descriptors.
+
+The IFs do not show any IFs relating to timer control of interaction between FEs. Not all error paths are considered.
+
+### 7.7.1 ITCC procedures
+
+The ITCC user invokes access to ITCC service by setting up a call to an ITCC card acceptor network. The user is then connected to an SRF which provides the mechanism of interaction between the ITCC user and the ITCC card acceptor network for the collection of information to enable access to the service.
+
+The interactions between the ITCC user and the SRF are assumed to be by DTMF in-band signalling. The SRF also provides voice prompts but specific content of the announcements is beyond the scope of this Recommendation.
+
+The sequence (e.g. PAN, PIN, Called Number) in which the information is sent from the ITCC user to the network is a national matter, and is also beyond the scope of this Recommendation.
+
+An outline of the sequence in which the procedures are invoked is shown in Figure 2, exit and error paths are not included.
+
+The main body of text of this Recommendation contains the description of the validation and call disposition procedures for the ITCC service as defined in Recommendation E.113. Other procedures that are out of the scope of standardization (national dependent) are reported in the appendixes.
+
+#### 7.7.1.1 Validation procedure
+
+The ITCC service is based on an automatic validation procedure that implies that the call handling Administration will query the database of the card issuing Administration to validate telephone charge cards used by customers who are making a call in a country other than their own.
+
+Recommendation E.113 “Validation procedures for the international telecommunications charge card service” defines the procedures for the validation process between Administrations. The validation process foresees the following messages:
+
+- **Authorization Request (M)**: is a message from the card acceptor network to the card issuer network which provides details of an attempt to use a telephone charge card (i.e. card validation).
+- **Request Response (M)**: is a message from the card issuer network to the card acceptor network to provide either a positive or negative response to the authorization request.
+
+The following is a high-level description of the network actions required in order to validate the ITCC service.
+
+According to Recommendation E.118 describing the card format, the identity of the ITCC card issuer can be deduced from the Primary Account Number. Moreover, if there is a service agreement between the card acceptor and the card issuer, then the SDF associated with the card acceptor network may contain some data related to the agreements with other ITCC service providers.

+Validation procedure
+
+The validation is undertaken by the ITCC card issuer using the information received by the SCF(ca) including PAN, PIN and eventually the Called Number<sup>1)</sup>. If authentication is successful, the ITCC service logic in the originating network can continue. If authentication fails, action could proceed to “Authentication rejection and retry” (see Figure II.1) or terminate the call to “Maximum retries reached” (see Figure III.1).
+
+#### 7.7.1.2 Call disposition procedure
+
+Recommendation E.113 “Validation procedures for the international telecommunications charge card service” foresees, based on bilateral agreement, the procedure for the transmission of call details to the card issuing Administration at the end of each ITCC call. This procedure, uses the following message:
+
+- **Call Disposition (O):** is a message from the card acceptor network to the card issuer network to track usage of the card against the credit limit of the customer and gather other statistics. The main purpose of this additional message is to provide, on a timely basis, better control against potential fraudulent use of the charge card.
+
+<sup>1)</sup> PAN (max. 19 digits)      PIN (Max. 4 digits)  
+ MII = 89  
+ CC      CLD No. (Recommendation E.164)  
+ Issuer ID      CLG No. (Recommendation E.164)  
+ ACT No.
+
+The following is a high-level description of the network actions required in order to update the threshold in SDF(ci).
+
+###### Outline
+
+- 1) The originating network sends to the card issuer network the call details including the estimated charge as soon as the call is completed.
+- 2) The card issuing network updates the usage value of the card and sends back a response.
+- 3) If follow-on is foreseen, a trigger condition was met during the called party initiated disconnection; the action proceeds to “Follow-on” (see Figure VII.1).
+
+It is assumed that the appropriate points of control for detecting call abandon of the Calling party and the call disconnect of Calling/Called party will always be appropriately armed.
+
+Call details information to be sent in a Call Disposition message must be obtained from the SSF upon completion of a call. Procedures to provide this information by SSF to SCF are national in nature and beyond the scope of this Recommendation (see Figure IV.1).
+
+###### 7.7.1.2.1 Information flow diagram

+
+The diagram illustrates the Call Disposition procedure. It shows five functional entities: FE2 SSF/CCF, FE6 SCF, FE8 SRF, FE7 SDF(ca), and FE9 SDF(ci). The process begins with FE2 sending a message 'Rp' to FE6. FE6 then sends 'Rq' to FE8, FE7, and FE9, and 'Rr' to FE8. FE6 sends 'Update Data' to both FE7 and FE9. FE7 sends '901' to FE9. FE9 sends 'Update Confirmation' back to FE6. Finally, FE6 sends a '(Note)' to FE8. A shaded box labeled 'Service Data Management SIB' encompasses the FE6, FE8, FE7, and FE9 entities. The reference 'T1166220-94/d04' is located at the bottom right of the diagram.

+
+### 7.7.2 Definition of individual information flows
+
+The Information Flows (IFs) contained in this subclause are those described in clauses 5 and 6/Q.1214. The information elements (IEs) shown as those which are either mandatory (M) or Optional but needed for ITCC service (O). All of them are related to the SCF-SDF interface.
+
+NOTE 1 – As far as the SCF-SDF interface is concerned, Study Group XI/4 decided to use the X.500 protocol for the SCF-SDF interface. After the September 1994 meeting, this Recommendation will be updated in order to consider the necessary modifications.
+
+The IFs are also cross-referenced to the Service Independent Building Block (SIB) in which the IF is described in clause 5/Q.1214.
+
+NOTE 2 – Based on the SG 4/11 final decision, also the Service Independent Building Block (SIB) description in clause 5/Q.1214 has to be updated accordingly.
+
+The IFs related to the SSF-SCF and SRF-SSF interfaces, as stated in 7.7.1, are outside the scope of this Recommendation as they refer to a part of the architecture that may be implemented both using IN/non-IN model. For simplicity, these IFs are shown in Appendix I.
+
+#### 7.7.2.1 Relationship Rq (SCF-SDF)
+
+The abbreviations for the SIBs and the relevant subclause numbers in Recommendation Q.1214 are:
+
+- Screen Screen 5.2.8/Q.1214
+- Service Data Management SDM 5.2.9/Q.1214
+
+The Screen SIB provides the capability for the SCF to perform a comparison of an identifier against a list located in a specified storage space in the SDF.
+
+The Service Data Management SIB provides the capability for the SCF to: retrieve, replace, increment and decrement data in a specified storage space in the SDF.
+
+Non-IN use of relationship Rq for SCF-SDF is essentially the same as that described using IN terminology.
+
+###### 7.7.2.1.1 SCF to SDF flows
+
+The Query IF is used to query an item of data held in the SDF.
+
+The Update Data IF when requested entails an automatic execution of the update.
+
+Query req. ind. – confirmed IF (SDM, Screen, Trans.)
+
+|      |                     |   |

+###### 7.7.2.1.2 SDF to SCF flows
+
+The Query Result IF is the response to a Query IF. Note that in INAP this IF maps on to the RESULT part of the Query operation.
+
+The Update Confirmation IF is the response to an Update Data IF. Note that in INAP this IF maps on to the RESULT part of the Update Data operation.

+
+The diagram illustrates the first example of an SDL procedure for card successful validation. It consists of two main parts: a request sequence and a response sequence.
+
+**Request Sequence:**
+
+- Starts with a start symbol (oval with two vertical lines).
+- Followed by a **Retrieve Request to SDF h** operation (rectangle with a right-pointing arrow).
+- A dashed line connects this operation to a data object: `Request from ITCC Service Logic to send a Retrieve`.
+- The next operation is **Retrieve to SDF h** (rectangle with a right-pointing arrow).
+- A dashed line connects this operation to a data object containing a structured list:
+
+```
+{object name
+{ {type providerId
+  value providerIdVar},
+{type pan
+  value panVar},
+{type pin
+  value pinVar}
+}
+selection
+{type pin
+  value pinVar}
+}
+```
+- The sequence ends with a **Waiting for SDF Response** symbol (oval).
+
+**Response Sequence:**
+
+- Starts with a **Waiting for SDF h Response** symbol (oval).
+- Followed by a **Retrieve Result from SDF h** operation (rectangle with a left-pointing arrow).
+- A dashed line connects this operation to a data object: `{entries {type pin value pinVar}}`.
+- The sequence ends with a stop symbol (circle with an 'X').
+
+The identifier `T1166240-94/d06` is located to the right of the response sequence.

+## **7.10 Allocation of FEs to physical locations**
+
+The functional entities depicted in Figure 1 include both IN and non-IN models. Therefore the functional entity and the physical entity relationship can be considered identical for either model.
+
+The PE used for the mapping are the following:
+
+**Service Switching Point:** The SSP provides switching functionalities, and if it is a local exchange, provides the user with access to the network. The SSP allows access to the service after a request for the service has been detected. It communicates with other PEs such as an SCP. Functionally the SSP contains CCF, SSF, and, if the SSP is a local exchange, a CCAF. An SCF, an SRF and an SDF may be optionally contained in the SSP.
+
+**Service Network Access Point:** This PE contains only the CCAF and CCF FEs. The SNAP cannot communicate with an SCF but has the capability to recognize a call requiring the service and route the call to an SSP.
+
+**Service Control Point:** The SCP contains the Service Logic Programs to provide services. SCP and SSP are connected by signalling network. An SCP contains an SCF and an SDF.
+
+**Intelligent Peripheral:** The IP provides resources for the user interaction with the network. Functionally an IP contains an SRF.
+
+**Service Switching and Control Point:** This is a combined SCP and SSP in a single node. Functionally it contains an SCF, SDF, CCAF, CCF and SSF. An SSCP may optionally contain an SRF.
+
+**Service Data Point:** The SDP contains the customer and network data which is accessed during the execution of a service. Functionally the SDP contains SDF.

+
+#### Access and identification procedure
+
+(This appendix does not form an integral part of this Recommendation)
+
+Regarding the access procedures, three different types can be foreseen: card reader procedure, auto access procedure and operator procedure. Since the choice of one of them is a national decision, it is out of the scope of this Recommendation. In this subclause an example of an ITCC call originated from a telephone not equipped with card reader using an auto access procedure (i.e. without operator assistance) is shown.
+
+The following is a high-level description of the network actions required when a user requests access to the ITCC service.
+
+#### Outline
+
+- 1) Service Access Code (SAC) and the Primary Account Number (PAN) input by the user.
+- 2) Recognition of SAC, suspension of the call processing in CCF, information flow to SCF advising initiation of ITCC request.
+- 3) The card acceptor's SCF, using the PAN information, applies call screening and retrieves from its own DB the card issuer identification information. Other call screening could be related to the retrieval of the appropriate language to use for the subsequent announcements. If it could be assumed that the ITCC card user DB can be deduced from the PAN number, the retrieve is not necessary.
+- 4) Connection of SRF (Establish Temporary Connection).
+- 5) Prompt for PIN code and collect it.
+- 6) Prompt user to input destination number and collect it.
+
+This solution is only one of the possible implementations at the end of this procedure. Regardless of which implementation is used however, the SCF will have obtained the same information for the call at the end of this procedure.
+
+#### Information flow diagram
+
+The information flow shows the access and identification procedures. See Figure I.1.
+
+![Sequence diagram showing the successful access and identification procedure between FE2 SSF/CCF, FE6 SCF, FE8 SRF, FE7 SDF(ca), and FE9 SDF(di). The process starts with an ITCC Call Request (Note 1) to FE2, followed by Initial DP (Rp) to FE6, Request Report BCSM event (Rp) to FE6, and Retrieve (Rr) to FE8. FE8 sends Retrieve Result (Rr) to FE6, which then sends it to FE7 (Note 3). FE6 sends Establish Temporary Connection (Rp) to FE2, followed by SETUP req. ind. (Rp) to FE8. FE8 sends resp. conf. Assist Request Instr. from SRF (Rr) to FE6, which then sends it to FE2 (Note 4). FE6 sends Prompt & Collect User information (Rr) to FE8, which prompts the user for PIN code (Note 5). FE8 sends Collected User Information Prompt & Collect User Information (Rr) to FE6, which then sends it to FE2 (Note 6). FE6 sends Collected User Information (Rr) to FE8, which prompts the user for Destination Number. FE8 sends the Destination Number (Rr) to FE6, which then sends it to FE2.](5a1abd59a95fa47ae192807de151e9eb_img.jpg)

+
+T1166290-94/d11
+
+#### NOTES
+
+- 1 The contents of SETUP req. ind. from FE1 (CCAF) to FE2 (SSF/CCF) are the SAC, the PAN and the Calling Number if present. This is one possible implementation. Other solutions can be envisaged. The nature of the req. ind. is dependent on the national network in use (PSTN, ISDN, PLMN).
+- 2 On initiation of the ITCC service, control points (DPs) are dynamically armed by Request BCSM Event Report req. ind. in order to detect the calling party abandon.
+- 3 This IF is optional and could be used to determine particular aspects of the service (e.g. SDM to be sent or country language to be played).
+- 4 The order in which the SRF sends the SETUP resp. conf. and the Assist Request Instruction from SRF req. ind. is not significant. There are several SRF connection procedures, related to the physical location of the SRF. This example refers to a case in which there is a direct path between SCP and IP.
+- 5 The user is prompted to input his PIN code by dialling digits or using a DTMF tone sender, for example. SCF-initiated disconnection of SRF is assumed, hence the SRF is not allowed to disconnect at the end of the user interaction.
+- 6 The user is prompted to input the destination number by the SRF, using Prompt and Collect User Information req. ind. The number is reported to SCF using Collect User Information req. ind.

+
+### **Validation Rejection and Retry procedure**
+
+(This appendix does not form an integral part of this Recommendation)
+
+The Validation Rejection and Retry procedure is used when a charge card validation result is not accepted. Treatment of the call at this point is implementation dependent. Figure II.1 uses a query to service databases to obtain information on services rejection and retry agreements. Using information retrieved, the calling user is requested to re-enter a PAN and PIN. This procedure ends when the SCF has collected the subsequent user information.
+
+#### **Outline**
+
+The following is a high-level description of the actions for a validation retry:
+
+- 1) Obtain service/user retry ability from card issuer and/or card accepting databases.
+- 2) Request SRF to prompt and collect subsequent PAN/PIN.
+- 3) Provide result from SRF to SCF.
+
+#### Information flow diagram
+
+The information flow shows the Validation and Retry procedure. See Figure II.1.
+
+![Sequence diagram showing the Validation rejection and retry procedure between FE2 SSF/CCF, FE6 SCF, FE8 SRF, FE7 SDF(ca), and FE9 SDF(ci).](b235edb1dbe659e2782c9a0e47775ca4_img.jpg)
+
+The diagram illustrates the Validation rejection and retry procedure across five functional entities (FEs): FE2 SSF/CCF, FE6 SCF, FE8 SRF, FE7 SDF(ca), and FE9 SDF(ci). The process involves several steps, including queries, updates, and prompts, with specific data flows and error handling paths.
+
+**Sequence of Events:**
+
+- Initial Query (Note 1):** FE6 SCF sends a Query (671) to FE7 SDF(ca). FE7 SDF(ca) returns a Query Result (902) to FE6 SCF.
+- Second Query (Note 2):** FE6 SCF sends a Query (672) to FE7 SDF(ca). FE7 SDF(ca) returns a Query Result (700) to FE6 SCF.
+- Update and Confirmation (Note 3):** FE6 SCF sends an Update (650) to FE8 SRF. FE8 SRF returns an Update Conf. (674) to FE6 SCF.
+- Prompt and Collect User Information (Note 4):** FE6 SCF sends a Prompt & Collect User Information (810) to FE8 SRF. FE8 SRF returns a Collected User Information Prompt & Collect User Information (622) to FE6 SCF.
+- PIN Collection:** FE6 SCF sends a PIN code to FE2 SSF/CCF. FE2 SSF/CCF returns a "Provide your PIN" message to FE6 SCF.
+- Final Query (Note 4):** FE6 SCF sends a Query Result (673) to FE7 SDF(ca). FE7 SDF(ca) returns a Query Result (900) to FE6 SCF.
+
+**Data Flows:**
+
+- Rp (Request Path):** FE2 SSF/CCF sends data to FE6 SCF.
+- Rq (Response Path):** FE6 SCF sends data to FE8 SRF.
+- Rr (Retry Path):** FE6 SCF sends data to FE7 SDF(ca).
+
+**Messages:**
+
+- "Wrong authentication, please retry. Provide your PAN"
+- "PAN code"
+- "Provide your PIN"
+- "PIN code"
+
+Sequence diagram showing the Validation rejection and retry procedure between FE2 SSF/CCF, FE6 SCF, FE8 SRF, FE7 SDF(ca), and FE9 SDF(ci).
+
+#### NOTES
+
+- 1 Once authentication fails, a count must be kept of the number of retry attempts. On first execution of this sequence, the limit set by the ITCC card issuer is retrieved from SDF(ci).
+- 2 On first execution of this sequence, the retry limit of originating network of ITCC card acceptor is retrieved from SDF(ca). The counter logic resides in SCF. It is assumed that the SCF would use the smaller of these two values as the allowed limit, should they be different.
+- 3 The count of authentication failures is now recorded in SDF(ci) for security and administration purposes.
+- 4 If authentication fails, the specific reason for failure should not be advised to the user, for security reasons. Therefore both the PAN and the PIN will need to be re-entered.

+## Appendix IV
+
+### Outgoing call (This appendix does not form an integral part of this Recommendation)
+
+Outgoing calls from an ITCC user may be a single call, in which the procedure terminates at the end of the call or may allow follow-on (see Appendix VII).
+
+**Outline**
+
+The following is a high-level description of the actions required to set up an outgoing call:
+
+- 1) Disconnection of SRF.
+- 2) Arm triggers to detect call set-up failure and to detect mid-call feature activation (if required) and activate an application timer on "Called party no answer" (if required).
+
+**Recommendation Q.86 (10/95)**      25
+
+- 3) Furnish charging operation (or other charging operation) for generation of billing record.

+
+The diagram illustrates a sequence of events for successful follow-on recognition. It features five functional entities (FEs) represented as vertical lifelines: FE2 SSF/CCF, FE6 SCF, FE8 SRF, FE7 SDF(ca), and FE9 SDF(ci). The sequence begins with FE2 sending a 'ra' (request acknowledgment) to FE6. FE6 then sends a 're' (request establishment) to FE8, with a note '(Note 1)' indicating a direct path. FE8 sends a 'SETUP req. ind.' (Setup request indication) to FE2. FE2 responds with a '250' (successful completion) to FE8. FE8 then sends a 'SETUP resp. conf.' (Setup response confirmation) to FE6. FE6 sends an 'Assist Request Instr. from SRF' to FE8. FE8 prompts and collects user information, sending a '620' (collect user information) to FE6. FE8 then sends an '810' (enter new destination) to FE2. FE2 sends a 'response=xxx' to FE8. Finally, FE8 sends 'Collected User Information' to FE6, with a '622' (collected user information) message.

+
+1 See Note in Figure 4.
+
+2 The order in which the SRF sends the SETUP resp. conf. and the Assist Request Instruction from SRF req. ind. is not significant. There are several SRF connection procedures, related to the physical location of the SRF. This example refers to the case in which there is a direct path between SCP and IP.

+# FOREWORD
+
+The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the International Telecommunication Union. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis.
+
+The World Telecommunication Standardization Conference (WTSC), which meets every four years, established the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics.
+
+ITU-T Recommendation Q.951, clauses 3, 4, 5 and 6 was prepared by the ITU-T Study Group XI (1988-1993) and was approved by the WTSC (Helsinki, March 1-12, 1993).
+
+# --- NOTES
+
+1 As a consequence of a reform process within the International Telecommunication Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place, the ITU Telecommunication Standardization Sector (ITU-T) was created as of 1 March 1993. Similarly, in this reform process, the CCIR and the IFRB have been replaced by the Radiocommunication Sector.
+
+In order not to delay publication of this Recommendation, no change has been made in the text to references containing the acronyms “CCITT, CCIR or IFRB” or their associated entities such as Plenary Assembly, Secretariat, etc. Future editions of this Recommendation will contain the proper terminology related to the new ITU structure.
+
+2 In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

+## STAGE 3 DESCRIPTION FOR NUMBER IDENTIFICATION SUPPLEMENTARY SERVICES USING DSS 1
+
+*(Helsinki, 1993)*
+
+# 3 Calling Line Identification Presentation (CLIP)
+
+## 3.1 Definition
+
+**calling line identification presentation (CLIP)** is a supplementary service offered to the called party which provides the calling party's ISDN number, possibly with sub-address information to the called party.
+
+## 3.2 Description
+
+#### 3.2.1 General description
+
+This supplementary service provides the ability of indicating the ISDN number of the calling line, with possible additional sub-address information (i.e. the Calling party sub-address information element), to the called party.
+
+The information provided to the called user consists of the ISDN number of the calling user in a form sufficient to allow the returning of the call (i.e. a subscriber number, a national number or an international number and optionally a sub-address if provided by the calling user).
+
+#### 3.2.2 Specific terminology
+
+For the purposes of this Recommendation, the following terms apply:
+
+A **served user** is the user of a particular ISDN number who has subscribed to the presentation of the calling line identification information in association with incoming calls. The served user is also known as the called user.
+
+A **calling user** is the user that initiated an incoming call at the served user. The calling user need not have subscribed to the Calling Line Identification Presentation supplementary service.
+
+An **ISDN number** is a number conforming to the numbering plan structure specified in Recommendation E.164.
+
+An **address** is the number of the calling user (normally ISDN number), and a sub-address if provided by that user.
+
+An **international number** is an ISDN number structured as specified in Recommendation E.164.
+
+A **national number; national significant number** is an ISDN number structured as specified in Recommendation E.164.
+
+A **subscriber number** is an ISDN number structured as specified in Recommendation E.164.
+
+A **default number** is an agreed number between the user at the calling side and the network provider.
+
+A **special arrangement** is an arrangement between a customer and a public network operator whereby customer supplied calling numbers are not screened by the public ISDN.

+CLIR     Calling Line Identification Restriction
+
+#### **3.2.3 Qualification on the applicability to telecommunication services**
+
+See Recommendation I.251.3.
+
+#### **3.2.4 State definitions**
+
+No specific state definitions are required.
+
+## **3.3 Operational requirements**
+
+#### **3.3.1 Provision/withdrawal**
+
+See Recommendation I.251.3.
+
+NOTE – Annex A contains some additional procedures to support the two Calling party number information elements delivery option. This is a network option.
+
+#### **3.3.2 Requirements on the originating network side**
+
+All information pertaining to CLIP, shall be inserted in the SETUP message sent as part of the basic call procedures according to 5/Q.931.
+
+In the case where no information is provided by the calling user (as part of the basic call procedures) the network shall provide the default number associated with the user access (in which the call was generated) in the originating local exchange.
+
+When the calling party information is provided by the user, the network can only verify that the number is within the range allocated to that user.
+
+Where a special arrangement exists with the calling user, no screening of the calling number they supplied, shall be performed.
+
+#### **3.3.3 Requirements in the network**
+
+This subclause is not applicable to DSS 1.
+
+#### **3.3.4 Requirements on the destination network side**
+
+See 3.5.2.3.
+
+### **3.4 Coding requirements**
+
+All information pertaining to CLIP is inserted in the SETUP message. 4.5.10/Q.931 and 4.5.11/Q.931 give the coding for the Calling party number and Calling party sub-address information elements which are required to support this service. The purpose of the Calling party number information element is to identify the origin of a call. The purpose of the Calling party sub-address information element is to identify a sub-address associated with the origin of the call.
+
+## **3.5 Signalling requirements**
+
+#### **3.5.1 Activation/deactivation/registration**
+
+Not applicable.
+
+#### **3.5.2 Invocation and operation**
+
+##### **3.5.2.1 Actions at the originating local exchange**
+
+###### **3.5.2.1.1 Normal operation**
+
+###### **3.5.2.1.1.1 Actions at the originating user**
+
+These procedures shall be provided as part of the basic service and the calling user need not have subscribed to the CLIP supplementary service.
+
+The numbering plan identification, to be indicated with the Calling party number information element, sent by the calling user, shall be either “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”.
+
+NOTE – Either coding may be used and the treatment of both by the network is identical.
+
+Where the calling number included by the calling user is complete the type of number to be indicated within the Calling party number information element, sent by the calling user, shall be one of the following:
+
+- “*Subscriber number*” – In the case where the complete subscriber number is sent.
+- “*National number*” – In the case where the complete national number is sent.
+- “*International number*” – In the case where the complete international number is sent.
+
+Where a partial calling number is included by the calling user (e.g., to indicate digits specific to the Direct-Dialling-In or the Multiple Subscriber Number supplementary services) the user shall set the type of number to be indicated within the Calling party number information element to “unknown”.
+
+###### **3.5.2.1.1.2 Actions at the originating local exchange if a special arrangement does not apply**
+
+These procedures shall be provided as part of the basic service and the calling user need not have subscribed to the CLIP supplementary service.
+
+When a SETUP message is received from the calling user, the network shall check to see if the Calling party number and Calling party sub-address information elements are included.
+
+If the Calling party number information element is received with a coding of the numbering plan identification field other than “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”, then the network shall discard the Calling party number information element and process the call as if that information was not received.
+
+The network shall set the value of the screening indicator based on the outcome of the screening of the calling number. The network shall disregard any value of the screening indicator, if received from the calling user.
+
+If the Calling party number information element is included, the network shall perform the screening function.
+
+NOTE 1 – Some networks may accept a full ISDN number in a Calling party number information element with the addition of a prefix or escape digits to the number digits field and the type of number field set to “unknown”.
+
+If the calling number received from the calling user is determined to be correct, the network shall set the screening indicator to “user-provided, verified and passed”.
+
+If the screening function fails the network shall note that the screening is failed and shall use a default number associated with the calling user. The network shall set the screening indicator to “network provided”.
+
+If the SETUP message does not contain the Calling party number information element the network shall use a default number associated with the calling user. The network shall set the screening indicator to “network provided”.
+
+In the case where the calling user provides only partial calling number information and the number is a valid digit sequence for the user access arrangement, the network shall complete the number as appropriate. The network shall set the screening indicator to “user-provided, verified and passed”.
+
+NOTE 2 – In some cases the network cannot guarantee that the completed number identifies an end user.
+
+The information determined by the procedures above, shall be forwarded to the destination local exchange, in association with the basic call request.
+
+The presentation indicator, as determined by the procedures of the CLIR supplementary service (see clause 4), shall be forwarded to the destination local exchange, in association with the basic call request.
+
+If the Calling party sub-address information element is available, it shall be passed transparently through the network.
+
+The actions at the originating local exchange when special arrangement does not apply are summarized in Table 3-1.

+###### 3.5.2.1.1.3 Actions at the originating local exchange if a special arrangement applies
+
+These procedures shall be provided as part of the basic service and the calling user need not have subscribed to the CLIP supplementary service.
+
+When a SETUP message is received from the calling user, the network shall check to see if the Calling party number and Calling party sub-address information elements are included.
+
+If the Calling party number information element is received with a coding of the numbering plan identification field other than “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”, then the network shall discard the Calling party number information element and process the call as if that information element was not received.
+
+If the Calling party number information element is received with the coding of the type of number field other than “national number” or “international number”, then the network shall discard the Calling party number information element and process the call as if that information element was not received.
+
+The network shall disregard any value of the screening indicator, if received from the calling user.
+
+If the SETUP message does not contain the Calling party number information element the network shall use a default number associated with the calling user. The network shall set the screening indicator to “network provided”.
+
+If the Calling party number information element is included the network shall set the screening indicator to “user-provided, not screened”.
+
+NOTE – For the above condition, the procedures of basic call will provide for another calling number to be transported through the network. This other calling number will contain the default number, with an associated screening indicator set to “network provided”.
+
+The information determined by the procedures above, shall be forwarded to the destination local exchange, in association with the basic call request.
+
+The presentation indicator, as determined by the procedures of the CLIR supplementary service (see clause 4) shall be forwarded to the destination local exchange, in association with the basic call request.
+
+If the Calling party sub-address information element is available, it shall be passed transparently through the network.
+
+The actions at the originating local exchange when special arrangement applies are summarized in Table 3-2.

+
+###### **3.5.2.3.1 Normal operation**
+
+When the network sends a SETUP message to the called user and if the called user is provided with the CLIP supplementary service, the network shall check to see if the calling number is available.
+
+If the calling number is available and presentation is allowed according to the presentation indicator supplied together with the calling number, the network shall include the Calling party number information element in the SETUP message sent to the called user. If provided, the network shall also include the Calling party sub-address information element in the SETUP message. The presentation and screening indicators associated with the calling number, and the calling sub-address, received at the destination exchange, shall be passed transparently to the called user.
+
+The numbering plan identification field shall be coded either “ISDN/telephony numbering plan” (see Recommendation E.164)” or “unknown”.
+
+If presentation is not allowed according to the presentation indicator supplied together with the calling number, the network shall include the Calling party number information element in the SETUP message sent to the called user. The presentation indicator in the Calling party number information element shall indicate “presentation restricted”. The network shall encode the screening indicator, numbering plan identification and the type of number according to one of the following options:
+
+- i) The screening indicator shall indicate “network provided”. The type of number and numbering plan identification shall be set to “unknown”.
+- ii) The screening indicator, numbering plan identification and the type of number shall be as received at the destination network.
+
+The network shall not include digits field. The network shall not include the Calling party sub-address information element in the SETUP message.
+
+If neither the calling number nor an indication that presentation is restricted is available at the destination local exchange the network shall include the Calling party number information element in the SETUP message sent to the called user. The presentation indicator shall be set to “number not available due to interworking”, and the screening indicator shall be set to “network provided”, the type of number and the numbering plan identification shall be set to “unknown” and the number digits field shall not be included. The network shall not include the Calling party sub-address information element, if provided, in the SETUP message.
+
+If the called user is not provided with the CLIP supplementary service, then neither the Calling party number nor the Calling party sub-address information elements shall be included in the SETUP message sent to the called user.
+
+If presentation is restricted but as a national network option the called user has the “override” category (e.g., police or emergency service) marked in the destination local exchange, the network shall include the Calling party number information element, and Calling party sub-address information element if the sub-address was supplied by the calling party in the SETUP message. In this case, the presentation and screening indicators shall be passed transparently to the called user.
+
+NOTE – If the presentation indicator in the Calling party number information element received by the user is set to “number not available due to interworking” or “presentation restricted”, the remaining information in the Calling party number information element should be ignored by the user.

+
+- The network shall send the Calling party number information element according to 3.5.2.3.1, sixth paragraph, and shall include no Calling party sub-address information element.
+- The network shall send the Calling party number information element according to 3.5.2.3.1, fourth paragraph, and shall include no Calling party sub-address information element.
+- The network shall send the Calling party number information element according to 3.5.2.3.1, second paragraph, and shall include the Calling party sub-address information element if the calling sub-address is available.
+
+For some other non-ISDNs, no complete calling number may be available to the ISDN and therefore the full number of the calling user cannot be given to the called user who has been provided with the CLIP supplementary service. In this case the network shall send the Calling party number information element according to 3.5.2.3.1, sixth paragraph, and shall include no Calling party sub-address information element.
+
+On calls incoming from some non-ISDNs, the calling number may be delivered to the destination ISDN with an indication of Calling Line Identity Restriction. In this case the network shall send the Calling party number information element according to 3.5.2.3.1, second paragraph, and shall include the Calling party sub-address information element if the calling sub-address is available.
+
+As a network option the originating network may restrict any address information identifying the calling user from being forwarded to another network.
+
+#### **3.7.2 Procedures for interworking with private ISDNs**
+
+The procedures specified in 3.5.2 shall be used.

+## **Annex A** (referred to in clause 3)
+
+### **Two Calling party number information elements delivery option**
+
+### **A.1 Scope**
+
+This annex specifies additional procedures to be supported for the delivery of two Calling party number information elements to the served user. The support of these procedures (or of a part of these) is a network option.
+
+These additional features shall have no impact and shall place no requirement whatsoever on the provision and operation of the CLIP supplementary service defined in this Recommendation by public ISDNs that do not support these additional features, nor on the interchangeability of terminals.
+
+### **A.2 Additional procedures at the destination network side**
+
+The procedures described in this annex pertain to networks capable of delivering two numbers to the called user.
+
+#### **A.2.1 Normal operation**
+
+The procedures described in 3.5.2.3.1 apply in the following situations:
+
+- a) only a single number is available for delivery at the terminating exchange;
+- b) presentation is restricted;
+- c) the called user is not provided with the CLIP supplementary service;
+- d) if the subscription option to two number delivery exists and the called user has not subscribed to two number delivery.
+
+When two numbers are available at the terminating exchange with screening indicators of one set to “network provided” and the other set to “user provided not screened”, the network shall deliver the information in two Calling party number information elements sent in a SETUP message to the called user.
+
+In addition, for some networks, when two numbers are available at the terminating exchange with screening indicators of one set to “network provided” and the other set to “user-provided, verified and failed”, the network shall deliver the information in two Calling party number information elements sent in a SETUP message to the called user.
+
+The order in which the Calling party number information elements appear in the SETUP message is a network option.
+
+If provided, the network shall also include the Calling party sub-address information element in the SETUP message. The presentation and screening indicators associated with the calling number, and the calling sub-address, received at the destination exchange, shall be passed transparently to the called user.
+
+#### **A.2.2 Exceptional procedures**
+
+Not applicable.
+
+### **A.3 Actions at the originating user**
+
+Actions at the originating user are as described in 3.5.2.1.1.1.
+
+### **A.4 Additional actions at the originating local exchange**
+
+The procedures of 3.5.2.1.1.2 shall apply except in the case where the screening function fails.
+
+When the screening function fails, the network shall set the screening indicator to “user-provided, verified and failed”.
+
+NOTE – For the above condition, the procedures of basic call will provide for another calling number to be transported through the network. This other calling number will contain the default number with an associated screening indicator set to “network provided”.
+
+The information determined by the procedures above shall be forwarded to the destination local exchange in association with the basic call request.
+
+The presentation indicator, as determined by the procedures of the CLIR supplementary service (see clause 4) shall be forwarded to the destination local exchange in association with the basic call request.
+
+If the Calling party sub-address information element is available, it shall be passed transparently through the network.
+
+The actions at the originating local exchange when screening fails are summarized in Table A.1.

+## 4 Calling Line Identification Restriction (CLIR)
+
+### 4.1 Definition
+
+**calling line identification restriction (CLIR)** is a supplementary service offered to the calling party to restrict presentation of the calling party’s ISDN number and sub-address to the called party.
+
+### 4.2 Description
+
+#### 4.2.1 General description
+
+When CLIR is applicable and activated the originating network shall provide the destination network with an indication that the calling user’s ISDN number and sub-address (if provided by the calling user) are not allowed to be presented to the called user. In this case no calling user number and sub-address shall be included in the call offered to the called user.
+
+The presentation restriction function shall not influence the forwarding of the calling party number within the network as part of the basic service procedures.
+
+#### 4.2.2 Specific terminology
+
+For the purposes of this Recommendation, the following terms apply:
+
+A **served user** is the user of a particular ISDN number who has subscribed to the restriction of the calling line identification information (on a permanent or on a per-call basis) in association with outgoing calls. The served user is also known as the calling user.
+
+A **called user** is the receiver of a call, initiated by the served user, on which CLIR has been activated.
+
+An ISDN number is a number conforming to the numbering plan and structure specified in Recommendation E.164.

+If the calling user wishes to override the default setting in the network, the SETUP message sent by the user shall contain the Calling party number information element with the presentation indicator set appropriately.
+
+#### **4.5.2.2     Actions at the originating local exchange**
+
+###### **4.5.2.2.1     Normal operation**
+
+If the calling user has subscribed to the Calling Line Identification Restriction supplementary service permanent mode, the presentation indicator received in the SETUP message will be ignored. The network shall set the presentation indicator to “presentation restricted”.
+
+If the calling user has subscribed to the CLIR supplementary service on a per-call basis and requests to override the default setting, the originating network shall set the presentation indicator according to that in the received Calling party number information element.
+
+The number digits, if included, shall be treated according to Table 3-1 or Table 3-2, and 3.5.2.1.1.
+
+If the CLIR is requested by the user on a per-call basis, and no Calling party number information element is included in the SETUP message, the originating network shall set the presentation indicator according to the subscribed default value.
+
+The presentation indicator shall be forwarded to the destination in association with the basic call request.

+
+#### **4.7.1 Interaction with other networks**
+
+On calls to or via non-ISDNs, it cannot be assured that a restriction indication can be carried to the destination network. As a national network option the originating network shall have the possibility to restrict any information identifying the calling party being forwarded to the destination network when CLIR is applicable. If a destination network receives a calling party number without any indication of presentation allowed or restricted, the destination network (the host network) will act according to its rules and regulations. For further information see 3.7.
+
+#### **4.7.2 Procedures for interworking with private ISDNs**
+
+The procedures specified in 4.5 shall be used.
+
+### **4.8 Signalling flows**
+
+The signalling flows are not included as they form an integral part of the basic call control procedures.

+
+## **5 Connected Line Identification Presentation (COLP)**
+
+### **5.1 Definition**
+
+**connected line identification presentation (COLP)** is a supplementary service offered to the calling party which provides the connected party's ISDN number, with possible additional sub-address information, to the calling party.
+
+### **5.2 Description**
+
+#### **5.2.1 General description**
+
+This supplementary service is not a dialling check but an indication to the calling subscriber of the connected ISDN number. In a full ISDN environment, the connected line identity must include all the information necessary to unambiguously identify the connected line.
+
+Moreover, the information on the connected line identity may include additional sub-address information (i.e. the Connected sub-address information element) generated by the connected user and transparently transported by the network. The network is not responsible for the content of this additional sub-address information.
+
+Unless COLR has been subscribed by the connected user, the network delivers the connected line identity to the calling user regardless of the terminal capability to handle the information.

+#### 5.2.2 Specific terminology
+
+For the purposes of this Recommendation, the following terms apply:
+
+A **served user** is the user of a particular ISDN number who has subscribed to the presentation of the connected line identification information in association with outgoing calls. The served user is also known as the calling user.
+
+A **connected user** is the user that responded to the served user call request at the destination network and has been awarded the call by the network. The connected user need not have subscribed to the Connected Line Identification Presentation supplementary service.
+
+An ISDN number is a number conforming to the numbering plan structure specified in Recommendation E.164.
+
+An international number is an ISDN number structured as specified in Recommendation E.164.
+
+A national number or a national significant number is an ISDN number structured as specified in Recommendation E.164.
+
+A subscriber number is an ISDN number structured as specified in Recommendation E.164.
+
+An address is the number of the connected user (normally ISDN number), and a sub-address if provided by that user.
+
+A default number is an agreed number between the user at the connected side and the network provider.
+
+A special arrangement is an arrangement between a customer and a public network operator whereby customer supplied connected numbers are not screened by the public ISDN.

+
+###### 5.5.2.1.1 Normal operation
+
+When the network sends a CONNECT message to the calling user and the calling user is provided with the COLP supplementary service, the network shall check to see if the connected number is available.
+
+If the connected number is available and presentation is allowed according to the presentation indicator supplied together with the connected number, the network shall include the Connected number information element in the CONNECT message sent to the calling user. If provided, the network shall also include the Connected sub-address information element in the CONNECT message. The presentation and screening indicators associated with the connected number and the connected sub-address received at the originating exchange shall be passed transparently to the calling user.
+
+The numbering plan identification field shall be coded either as “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”.
+
+If presentation is not allowed according to the presentation indicator supplied together with the connected number, the network shall include the Connected number information element in the CONNECT message sent to the calling user. The presentation indicator in the Connected number information element shall indicate “presentation restricted”. The network shall encode the screening indicator, numbering plan identification and the type of number according to one of the following options:
+
+- i) The screening indicator shall indicate “network provided”. The type of number and numbering plan identification shall be set to “unknown”.
+- ii) The screening indicator, numbering plan identification and the type of number shall be passed as received at the destination network.
+
+The network shall not include number digits field. The network shall not include the Connected sub-address information element, in the CONNECT message.
+
+If neither the connected number nor an indication that presentation is restricted is available at the originating local exchange, the network shall include the Connected number information element in the CONNECT message sent to the calling user. The presentation indicator shall be set to “number not available due to interworking” and the screening indicator shall be set to “network provided”, the type of number and numbering plan identification shall be set to “unknown” and the number digits field shall not be included. The network shall not include the Connected sub-address information element, if provided, in the CONNECT message.
+
+If the calling user is not provided with the COLP supplementary service, then neither the Connected number nor the Connected sub-address information elements shall be included in the CONNECT message sent to the calling user.
+
+If presentation is restricted but as a national network option the calling user has the “override” category (e.g. police or emergency service) marked in the originating local exchange, the network shall include the Connected number information element and Connected sub-address information element if the sub-address was supplied by the connected user, in the CONNECT message. In this case, the presentation and screening indicators shall be passed transparently to the calling user.
+
+NOTE – If the presentation indicator in the Connected number information element received by the user is set to “number not available due to interworking” or “presentation restricted”, the remaining information in the Connected number information element should be ignored by the user.
+
+###### **5.5.2.1.2 Exceptional procedures**
+
+Not applicable.
+
+#### **5.5.2.2 Actions at the transit exchange**
+
+This subclause is not applicable to DSS 1.
+
+#### **5.5.2.3 Actions at the destination local exchange**
+
+###### **5.5.2.3.1 Normal operation**
+
+###### **5.5.2.3.1.1 Action at the destination user**
+
+These procedures shall be provided as part of the basic service and the connected user need not have subscribed to the COLP supplementary service.
+
+The numbering plan identification to be indicated within the Connected number information element, sent by the connected user shall be either “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”.
+
+NOTE – Either coding may be used and the treatment of both by the network is identical.
+
+Where the connected number included by the connected user is complete, the type of number to be indicated within the Connected number information element, sent by the connected user, shall be one of the following:
+
+- “*Subscriber number*” – In the case where the complete subscriber number is sent.
+- “*National number*” – In the case where the complete national number is sent.
+- “*International number*” – In the case where the complete international number is sent.
+
+Where a partial connected number is included by the connected user (e.g. to indicate digits specific to the Multiple Subscriber Number supplementary service) the user shall set the type of number to be indicated within the Connected number information element to “unknown”.
+
+###### **5.5.2.3.1.2 Actions at the destination local exchange if a special arrangement does not apply**
+
+These procedures shall be provided as part of the basic service and the connected user need not have subscribed to the COLP supplementary service.
+
+If multiple CONNECT messages are received from the called user, the network shall only perform the following procedures when it has decided which CONNECT message to acknowledge.
+
+Where a CONNECT message is received from the connected user, the network shall check to see if the Connected number and Connected sub-address information elements are included.
+
+If the Connected number information element is received with a coding of the numbering plan identification field other than “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”, then the network shall discard the Connected number information element and process the call as if that information was not received.
+
+The network shall set the value of the screening indicator based on the outcome of the screening of the connected number. The network shall disregard any value of the screening indicator, if received from the connected user.
+
+If the Connected number information element is included, the network shall perform the screening function.
+
+NOTE 1 – Some networks may accept a full ISDN number with the addition of a prefix or escape digits to the number digits field and the type of number field set to “unknown”.
+
+If the connected number received from the connected user is determined to be correct, the network shall set the screening indicator to “user-provided, verified and passed”.
+
+If the screening function fails, the network shall note that the screening is failed and shall use a default number associated with the connected user. The network shall set the screening indicator to “network provided”.
+
+If the CONNECT message does not contain the Connected number information element, the network shall use a default number associated with the connected user. The network shall set the screening indicator to “network provided”.
+
+In the case where the connected user provides partial connected number information, and the number is a valid digit sequence for the user access arrangement, the network shall complete the number as appropriate. The network shall set the screening indicator to “user-provided, verified and passed”.
+
+NOTE 2 – In some cases the network cannot guarantee that the completed number identifies an end user.
+
+The information, as determined by the procedures above, shall be forwarded to the originating local exchange, in association with the basic call response.
+
+The presentation indicator, as determined by the procedures of the COLR supplementary service (see clause 6), shall be forwarded to the originating local exchange, in association with the basic call response.
+
+If the Connected sub-address information element is available, it shall be passed transparently through the network.
+
+The actions at the destination local exchange if a special arrangement does not apply are shown in Table 5-2.
+
+###### **5.5.2.3.1.3 Actions at the destination local exchange if a special arrangement applies**
+
+These procedures shall be provided as part of the basic service and the connected user need not have subscribed to the COLP supplementary service.
+
+If multiple CONNECT messages are received from the called user, the network shall only perform the following procedures when it has decided which CONNECT message to acknowledge.
+
+When a CONNECT message is received from the connected user, the network shall check to see if the Connected number and Connected sub-address information elements are included.
+
+If the Connected number information element is received with a coding of the numbering plan identification field other than “ISDN/telephony numbering plan” (see Recommendation E.164) or “unknown”, then the network shall discard the Connected number information element and process the call as if that information element was not received.
+
+If the Connected number information element is received with a coding of the type of number field other than “national number” or “international number”, then the network shall discard the Connected number information element and process the call as if that information element was not received.
+
+If the Connected number information element is received with a coding of the numbering plan identification field other than “ISDN/telephony number plan” (see Recommendation E.164) or “unknown”, then the network shall discard the Connected number information element and process the call as if that information element was not received.
+
+The network shall disregard any value of the screening indicator, if received from the connected user.

+
+#### **5.7.1 Interaction with non-ISDNs**
+
+On calls destined for some non-ISDNs, the connected number may be delivered to the originating ISDN without an indication of connected line identity restriction. In this case a number of options exist and the selection of the following options is according to the network rules and regulations:
+
+- The network shall send the Connected number information element according to 5.5.2.1.1, sixth paragraph, and shall include no Connected sub-address information element.
+- The network shall send the Connected number information element according to 5.5.2.1.1, fourth paragraph, and shall include no Connected sub-address information element.
+- The network shall send the Connected number information element according to 5.5.2.1.1, second paragraph, and shall include the Connected sub-address information element if the connected sub-address is available.
+
+For some other non-ISDNs, no complete connected number may be available to the ISDN and therefore the full number of the connected user cannot be given to the calling user who has been provided with the COLP supplementary service. In this case the network shall send the Connected number information element according to 5.5.2.1.1, sixth paragraph, and shall include no Connected sub-address information element.
+
+On calls destined for some non-ISDNs, the connected number may be delivered to the originating ISDN with an indication of connected line identity restriction. In this case the network shall send the Connected number information element according to 5.5.2.1.1, second paragraph, and shall include the Connected sub-address information element if the connected sub-address is available.
+
+As a network option, the destination network may restrict any information identifying the connected user from being forwarded to another network.
+
+#### **5.7.2 Procedures for interworking with private ISDNs**
+
+These procedures specified in 5.5.2 shall be used.
+
+NOTE – The provision of the special arrangement where an access is used by a private network is especially appropriate.
+
+### **5.8 Signalling flows**
+
+The signalling flows are not included as they are an integral part of the basic call control procedures.
+
+### **5.9 Parameter values (timers)**

+# **6 Connected Line Identification Restriction (COLR)**
+
+## **6.1 Definition**
+
+**connected line identification restriction (COLR)**fs is a supplementary service offered to the connected party to restrict presentation of the connected party's ISDN number and sub-address to the calling party.
+
+### **6.2 Description**
+
+#### **6.2.1 General description**
+
+When COLR is applicable and activated, the destination network shall provide the originating network with an indication that the connected user's ISDN number and sub-address information is (if provided by the connected user) are not allowed to be presented to the calling user. In this case no connected number and sub-address shall be included in the call connected information to the calling user.
+
+The presentation restriction function shall not influence the forwarding of the connected number within the network as part of the basic service procedures.
+
+#### **6.2.2 Specific terminology**
+
+For the purposes of this Recommendation, the following terms apply:
+
+A **served user** is the user of a particular ISDN number who has subscribed to the restriction of the connected line identification information (on a permanent or on a per-call basis) in association with incoming calls. The served user may also be known as the connected user.
+
+A **calling user** is the initiator of a call, received by the served user, on which COLR has been activated.
+
+An ISDN number is a number conforming to the numbering plan and structure specified in Recommendation E.164.

+#### **6.2.3 Qualification on the applicability to telecommunication services**
+
+See Recommendation I.251.6.
+
+#### **6.2.4 State definition**
+
+No specific states are required.
+
+### **6.3 Operational requirements**
+
+#### **6.3.1 Provision/withdrawal**
+
+See Recommendation I.251.6.
+
+#### **6.3.2 Requirements on the originating network side**
+
+See 6.5.2.1.
+
+#### **6.3.3 Requirements in the network**
+
+This subclause is not applicable to DSS 1.
+
+#### **6.3.4 Requirements on the destination network side**
+
+All information pertaining to COLR is inserted in the CONNECT message sent as part of the basic call procedures according to 5/Q.931.
+
+### **6.4 Coding requirements**
+
+The same as for 5.4.
+
+### **6.5 Signalling requirements**
+
+#### **6.5.1 Activation/deactivation/registration**
+
+Not applicable.
+
+#### **6.5.2 Invocation and operation**
+
+##### **6.5.2.1 Actions at the originating local exchange**
+
+###### **6.5.2.1.1 Normal operation**
+
+The actions to be performed at the originating local exchange are provided as part of the COLP supplementary service, described in 5.5.2.1.1.
+
+###### **6.5.2.1.2 Exceptional procedures**
+
+Not applicable.
+
+#### **6.5.2.2 Actions at the transit exchange**
+
+This subclause is not applicable to DSS 1.
+
+#### **6.5.2.3 Action at the destination user**
+
+If the connected user wishes to override the default setting in the network, the CONNECT message sent by the user shall contain the Connected number information element with the presentation indicator set appropriately.
+
+#### **6.5.2.4 Actions at the destination local exchange**
+
+###### **6.5.2.4.1 Normal operation**
+
+If the connected user has subscribed to the Connected Line Identification Restriction supplementary service permanent mode, the presentation indicator received in the CONNECT message will be ignored. The network shall set the presentation indicator to “presentation restricted”.
+
+If the connected user has subscribed to the COLR supplementary service on a per-call basis and requests to override the default setting, the destination network shall set the presentation indicator according to that in the received Connected number information element.
+
+The digits, if included, shall be treated according to Table 5-2 or Table 5-3, and 5.5.2.3.1.
+
+If COLR is requested by the user on a per-call basis, and no Connected number information element is included in the CONNECT message, the destination network shall set the presentation indicator according to the subscriber value.
+
+The presentation indicator shall be forwarded to the originating network in association with the basic call response.
