18、or Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective o
19、rganization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. International Standards are draf
20、ted 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 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voti
21、ng. 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 of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for ide
22、ntifying 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 Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC
23、. Annex A forms a normative part of this International Standard. Annexes B, C, D and E are for information only. ISO/IEC 21889:2001(E) vi ISO/IEC 2001 All rights reservedIntroduction This International Standard is one of a series of Standards defining services and signalling protocols applicable to
24、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 Standard specifies the signalling protocol for use at the Q reference
25、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 is based upon the practical experience of ECMA member companies and the
26、 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. INTERNATIONAL STANDARD ISO/IEC 21889:2001(E) ISO/IEC 2001 All rights reserved 1Information
27、 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 protocol for the support of the
28、 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 feature which allows the assign
29、ment 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 supplementary services and/o
30、r 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 not precluded. The Q refere
31、nce 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 requirements identified by the s
32、tage 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 supplementary services spe
33、cified 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 Standard is applicable t
34、o 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 International Standard includes
35、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 following normative documents
