27、onal Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established
28、by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field
29、of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to the national bodies for voting. Publication as an International Standard requires approval by at least 75% of t
30、he national bodies casting a vote. International Standard ISO/IEC 13866 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 6, Telecommunications and information exchange between systems. Annex A of this International Standard is for information only. vi
31、0 ISOAEC ISOhEC 13866:1995 (E) Introduction This International Standard is one of a series of standards defining services and signalling protocols applicable to Private Integrated Services Networks (PISN). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of Standards
32、 for Open Systems Interconnection as defined by ISOAEC. This particular International Standard specifies the Call Completion supplementary services. vii INTERNATIONAL STANDARD 0 ISO/IEC ISO/IEC 13866:1995(E) Information technology - Telecommunications and information exchange between systems - Priva
33、te Integrated Services Network - Specification, functional model and information flows - Call completion supplementary services 1 Scope This International Standard, specifies supplementary services Call Completion (SS-CC), which are applicable to various basic services supported by Private Integrate
34、d Services Network (PISN). Basic services are specified in ISOAEC 11574. SS-CC consists of two Supplementary services: the Completion of Calls to Busy Subscribers supplementary service (SS-CCBS) and the Completion of Calls on No Reply supplementary service (SS-CCNR). SS-CCBS allows completion of a c
35、all to a subscriber that was unsuccessful because of a busy condition and SS-CCNR allows completion of a call to a subscriber that was unsuccessful because the subscriber, afthough alerted, did not answer. Supplementary service specifications are produced in three stages, according to the method des
36、cribed in CCllT Recommendation 1.130. This International Standard specifies the stage 1 and stage 2 specifications of SS-CC. The stage 1 specifications (clauses 6 and 7) specify the supplementary services as seen by the users of PISNs. The stage 2 specification (clause 8) specifies the functional en
37、tities involved in the supplementary services and the information flows between them. 2 Conformance In order to conform to this International tandard, a Stage 3 Standard shall specify signalling protocols and equipment Behaviour that are capable of being used in a PISN which supports the supplementa
38、ry services specified in this International Standard. This means that, to claim conformance a Stage 3 Standard is required to be adequate for the support of those aspects of 1 ISO/IEC 13866: 1995 (El, 0 ISO/IEC the stage 1 and stage 2 clauses which are relevant to the interface or equipment to which
39、 the stage 3 standard applies. The stage 1 and stage 2 clauses which a stage 3 standard for the Completion of Calls to Busy Subscribers (CCBS) supplementary service shall support are clauses 6 and 8 respectively. The stage 1 and stage 2 clauses which a stage 3 Standard for the Completion of Calls on
40、 No Reply (CCNR) supplementary service shall support are clauses 7 and 8 respectively. 3 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated wer
41、e valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
