3、ion, Functional Model andInformation Flows -Identification Supplementary Services(ISSD).Brief HistoryThis Standard is one of a series of ECMA Standards defining services and signalling protocols applicable to Private IntegratedServices Networks (PISNs). The series uses ISDN concepts as developed by

4、ITU-T and conforms to the framework ofInternational Standards for Open Systems Interconnection as defined by ISO/IEC. It has been produced under ITSTC workitem M-IT-05 2.2.1 for Bon de Commande 76B/D.1 and under ETSI work item RE/ECMA-00139.This particular Standard specifies the Identification suppl

5、ementary services (Calling Line Identification Presentation,Connected Line Identification Presentation, and Calling/Connected Line Identification Restriction), which allow a userinvolved in a call to receive information concerning the identity (number and subaddress) of the other user in the call. I

6、naddition a user can prevent the presentation of his number to other users. Corresponding services are specified for publicISDNs in CCITT recommendations I.251 and Q.81 (1992), and annex A to this Standard provides a comparison.This Standard is based upon the practical experience of ECMA member comp

7、anies and the results of their active andcontinuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardizationbodies. It represents a pragmatic and widely based consensus.Compared to the 1st and 2nd Editions of Standard ECMA-148 (published by ECMA in

8、December 1990 and June 1993respectively), this 3rd Edition incorporates changes in order to achieve complete alignment with International StandardISO/IEC 14136:1995(E) published by ISO/IEC in June 1995.Adopted as 3rd Edition of Standard ECMA-148 by the General Assembly of June 1997.- i -Table of con

23、 Presentation (SS-COLP) and Calling/Connected Line IdentificationRestriction (SS-CLIR), which are applicable to various basic services supported by Private Integrated ServicesNetworks (PISN). Basic services are specified in ECMA-142.Calling Line Identification Presentation (SS-CLIP) is a supplementa

24、ry service which is offered to the called user andwhich provides the calling users PISN number, and possibly a subaddress, to the called user.Connected Line Identification Presentation (SS-COLP) is a supplementary service which is offered to the calling userand which provides the called (connected)

25、users PISN number, and possibly a subaddress, to the calling user.Calling/connected Line Identification Restriction (SS-CLIR) is a supplementary service offered to a user to restrictpresentation of that users PISN number to another user.Supplementary service specifications are produced in three stag

26、es, according to the method described in ETS 300 387.This Standard contains the stage 1 and stage 2 specifications of SS-CLIP, SS-COLP and SS-CLIR. The stage 1specifications (clauses 6, 7 and 8) specify the supplementary services as seen by users of PISNs. The stage 2specifications (clauses 9, 10 an

27、d 11) identify the functional entities involved in the supplementary services and theinformation flows between them.2 ConformanceIn order to conform to this Standard, a stage 3 Standard shall specify signalling protocols and equipment behaviourthat are capable of being used in a PISN which supports

28、the supplementary services specified in this Standard. Thismeans that, to claim conformance, a stage 3 Standard is required to be adequate for the support of those aspects ofclauses 6, 7 and 8 (stage 1) and clauses 9, 10 and 11 (stage 2) which are relevant to the interface or equipment to whichthe s

29、tage 3 Standard applies.3 References (normative)The following standards contain provisions which, through reference in this text, constitute provisions of this Standard.All standards are subject to revision, and parties to agreements based on this Standard are encouraged to investigate thepossibilit

41、SN provides the called user with the PISN number of the calling user whenever an incoming call ispresented. The number provided should be sufficient to enable the called user to return the call.The calling user number may be accompanied by the calling user subaddress.6.1.2 Qualifications on applicab

42、ility to telecommunication servicesSS-CLIP is applicable to all basic services defined in ECMA-142.6.2 Procedure6.2.1 Provision/withdrawalSS-CLIP shall be generally available. There is no need for service profile control.Some users may have a service profile which permits the override of calling lin

43、e identification restriction.6.2.2 Normal procedures6.2.2.1 Activation/deactivation/registration/interrogationSS-CLIP shall be permanently activated. No information needs to be registered with the PISN for thissupplementary service, and therefore interrogation is not applicable.6.2.2.2 Invocation an

44、d operationThe PISN shall provide the called user with the calling user number at the same time as indicating an incomingcall.The number presented shall be accompanied by indications of the numbering plan and type of number, andshould be sufficient to unambiguously identify the calling user.Where th

45、e number presented has been wholly or partially provided by the calling user, it shall be marked “userprovided, verified and passed“. Otherwise it shall be marked “network-provided“.- 4 -If the calling user has also provided a calling user subaddress, it shall be delivered to the called user alongwi

46、th the calling user number.In some cases where calling line identification restriction has been invoked, there may be certain categories ofcalled user that have the service profile to override this restriction and have the calling user number presented,e.g. emergency stations, PISN attendants. In th

47、ese circumstances, presentation shall include an indication thatrestriction has been invoked.6.2.3 Exceptional procedures6.2.3.1 Activation/deactivation/registration/interrogationNot applicable.6.2.3.2 Invocation and operationThere are two exceptions when the calling user number is not presented to

48、the called user: when calling line identification restriction has been invoked (see definition of Calling/Connected LineIdentification Restriction) and the called user does not have the service profile to override this restriction;and when the calling user number is not available, e.g. due to interw

49、orking with the analogue telephonenetwork (PSTN).In such cases the called user shall receive an indication of the situation. In either case the called user canreceive the calling user subaddress, if available.6.3 Interaction with other supplementary services and ANFsInteractions with other supplementary services and ANFs for which PISN standards were available at the time ofpublication of this Standard are specified below.6.3.1 Connected Line Identification Presentation (SS-COLP)No interaction.6.3.2 Calling/Connected Line Identification Restriction (SS-CLIR)The call
