National bodies that are members of ISO or IEC p
22、articipate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governm
23、ental and non-governmental, in liaison with ISO and IEC, also take part in the work. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC
24、 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements
25、of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. International Standard ISO/IEC 21889 was prepared by ECMA (as ECMA-314) and was adopted, under a special “fast-track procedure”, by Joint Techn
26、ical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. Annex A forms a normative part of this International Standard.

28、 of Standards defining services and signalling protocols applicable to Private Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This International
29、 Standard specifies the signalling protocol for use at the Q reference point in support of the Call Identification and Call Linkage Additional Network Feature. The protocol defined in this International Standard forms part of the PSS1 protocol (informally known as QSIG). This International Standard
30、is based upon the practical experience of ECMA member companies and the results of their active and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus. Copyright Internati

32、ts reserved 1 Information technology Telecommunications and information exchange between systems Private Integrated Services Network Inter- exchange signalling protocol Call Identification and Call Linkage Additional Network Feature 1 Scope This International Standard specifies the signalling protoc
33、ol for the support of the Call Identification and Call Linkage Additional Network Feature (ANF-CIDL) at the Q reference point between Private Integrated Network Services Exchanges (PINXs) connected together within a Private Integrated Services Network (PISN). ANF-CIDL is an additional network featur
34、e which allows the assignment of a Global Call Identification (GID) to identify a call end-to-end over the call route (i.e. between the two end PINXs). As an option, a Thread Identification (TID) may be assigned to different calls which are logically linked together due to the operation of other sup
35、plementary services and/or ANFs. Additionally a Leg Identification (LID) may be assigned, to identify the different legs of a call. NOTE 1 - This ANF has been developed to support the use of CSTA (ISO/IEC 18051) in a networked environment, i.e. in a PISN. Use of this ANF for other applications is no
36、t precluded. The Q reference point is defined in ISO/IEC 11579-1. Supplementary Service specifications are produced in three stages and according to the method specified in ETS 300 387. This International Standard contains the stage 3 specification for the Q reference point and satisfies the require
37、ments identified by the stage 1 and stage 2 specifications in ISO/IEC 21888. The signalling protocol for ANF-CIDL operates on top of the signalling protocol for basic circuit switched call control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of s
38、upplementary services specified in ISO/IEC 11582. This International Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between Call Identification and Call Linkage and other supplementary services and ANFs. This International
39、 Standard is applicable to PINXs which can be interconnected to form a PISN. 2 Conformance In order to conform to this International Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation Conformance Statement (PICS) proforma in annex A. Conformance to this Interna
40、tional Standard includes conforming to those clauses that specify protocol interactions between ANF-CIDL and other supplementary services and ANFs for which signalling protocols at the Q reference point are supported in accordance with the stage 3 standards concerned. 3 Normative references The foll
41、owing normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this Internationa
