The series

4、uses the ISDN concepts as developed by ITU-T and conforms to theframework of International Standards for Open Systems Interconnection as defined by ISO/IEC. It has been producedunder ETSI work item DEN/ECMA-00202.This Standard specifies the Call Identification and Call Linkage (CIDL) additional netw

5、ork feature.This Standard is based upon the practical experience of ECMA member companies and the results of their active andcontinuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and nationalstandardization bodies. It represents a pragmatic and widely based consen

6、sus.There is currently no equivalent service specified by ITU-T or ETSI for public ISDN.This ECMA Standard is contributed to ISO/IEC JTC1 under the terms of the fast-track procedure, for adoption as anISO/IEC International Standard.This ECMA Standard has been adopted by the General Assembly in Septe

17、 167.5 Allocation of Functional Entities to physical equipment 177.6 Interworking considerations 171ScopeThis Standard specifies the Additional Network Feature (ANF) Call Identification and Call Linkage (CIDL),which is applicable to various basic services supported by Private Integrated Services Net

18、works (PISN). Basicservices are specified in ECMA-142.ANF-CIDL is an additional network feature which allows the identification and correlation of callsthroughout a PISN by assigning unambiguous identifiers to each new call and also, as an option, totransformed and logically linked calls.NOTE 1This

19、ANF has been developed to support the use of CSTA (ECMA-269) in a networked environment, i.e. in aPISN. Use of this ANF for other applications is not precluded.Supplementary service specifications are produced in three stages, according to the method described inETS 300 387. This Standard contains t

20、he stage 1 and stage 2 specifications of ANF-CIDL. The stage 1specification (clause 6) specifies the general feature principles and capabilities. The stage 2 specification(clause 7) identifies the Functional Entities involved in the supplementary service and the information flowsbetween them.2 Confo

21、rmanceIn order to conform to this Standard, a stage 3 standard shall specify signalling protocols and equipmentbehaviour that are capable of being used in a PISN which supports the supplementary service specified in thisStandard. This means that, to claim conformance, a stage 3 standard is required

22、to be adequate for the supportof those aspects of clause 6 (stage 1) and clause 7 (stage 2) which are relevant to the interface or equipment towhich the stage 3 standard applies.3 References (normative)The following standards contain provisions which, through reference in this text, constitute provi

23、sions of thisStandard. All standards are subject to revision, and parties to agreements based on this Standard areencouraged to investigate the possibility of applying the most recent editions of the standards indicatedbelow.In the case of references to ECMA Standards that are aligned with ISO/IEC I

If two ore more calls

45、 are logically linked together (i.e. due to Supplementary Service / ANFinteraction), the Thread IDs of all these calls are updated (i.e. replaced / overwritten) with the currentThread ID of one of these calls.- 4 -5 List of acronymsANF Additional Network FeatureANF-CIDL ANF Call Identification and C
