National bodies that are members of IS0 or IEC
12、 participate in the development of International Standards through technical committees established 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, gover
13、nmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field 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 national bo
14、dies for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 14841 was prepared by ECMA (as Standard ECMA- 191) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee I
15、SO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of IS0 and IEC. OISO/IEC ISO/IEC 14841:1996 (E) Introduction This International Standard is one of a series of International Standards defining services and signalling protocols applicable to Private Integrated Se
16、rvices Networks (PISNs). The series uses ISDN concepts as developed by lTU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This particular International Standard specifies the Call Offer supplementary service. INTERNATIONAL STANDARD
17、ISOmx ISO/IEC 14841:1996 (E) Information technology - Telecommunications and information exchange between systems - Private Integrated Services Network - Specification, functional model and information flows - Call offer supplementary service 1 Scope This International Standard specifies the Call Of
18、fer supplementary service (SS-CO), which is applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. Call Offer (SS-CO) is a supplementary service which, on request from the calling user (or on that users behalf), e
19、nables a call to be offered to a busy called user and to wait for that called user to accept this call. Supplementary service specifications are produced in three stages, according to the method described in CCITT Recommendation 1.130. This International Standard contains the stage 1 and stage 2 spe
20、cifications of SS-CO. The stage 1 specification (clause 6) specifies the supplementary service as seen by users of PISNs. The stage 2 specification (clause 7) identifies the functional entities involved in the supplementary service and the information flows between them. Note 1 - For this Internatio
21、nal Standard, stage 2 does not consider the split of functionality between a functional terminal and the local PINX. Terminal functions and local PINX functions are included in the same functional entity. 2 Conformance In order to conform to this International Standard, a stage 3 International Stand
22、ard shall specify signalling protocols and equipment behaviour that are capable of being used in a PISN which supports the supplementary service specified in this International Standard. This means that, to claim conformance, a Stage 3 International Standard is required to be adequate for the suppor
23、t of those aspects of clause 6 (stage 1) and clause 7 (stage 2) which are relevant to the interface or equipment to which the Stage 3 International Standard applies. 3 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this
24、 International Standard. At the time of publication, the editions indicated were 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
