29、A - Bibliography 72ISO/IEC 13872:2003(E) ISO/IEC 2003 All rights reserved vii Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO o
30、r IEC participate 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,
31、governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directive
32、s, Part 2. The main task of the joint technical committee is to prepare International Standards. 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 nat
33、ional bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 13872 was prepared by ECMA (as ECMA-173) and was adopted
34、, 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. This second edition cancels and replaces the first edition (ISO/IEC 13872:1995), which has been technically revised. ISO/IEC
35、13872:2003(E) viii ISO/IEC 2003 All rights reserved Introduction This International Standard is one of a series 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
36、framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This International Standard specifies the Call Diversion supplementary services: Call Forwarding Unconditional (SS-CFU) Call Forwarding Busy (SS-CFB) Call Forwarding No Reply (SS-CFNR) Call Deflection (SS-CD
37、)This International Standard 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 JTC 1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based
38、consensus. ISO/IEC 2003 All rights reserved 1 1S c o p eThis International Standard specifies the supplementary services Call Forwarding Unconditional (CFU), Call Forwarding Busy (CFB), Call Forwarding No Reply (CFNR) and Call Deflection (CD), which are applicable to various basic services supported
39、 by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574.SS-CFU, SS-CFB and SS-CFNR are supplementary services which apply during call establishment providing a diversion of an incoming call to an other destination. SS-CD is a supplementary service which allows
40、a served user to respond to an incoming call by requesting redirection of that call to another number specified in the response.Supplementary service specifications are produced in three stages, according to the method described in ETS 300 387. This International Standard contains the stage 1 and st
41、age 2 specifications of the Call Diversion supplementary services. The stage 1 specifications (clauses 6, 7, 8 and 9) specify the supplementary services as seen by users of PISNs. The stage 2 specification (clause 10) identifies the functional entities involved in the supplementary services and the
42、information flows between them. 2 ConformanceIn order to conform to this International Standard, a stage 3 standard shall specify signalling protocols and equipment behaviour that are capable of being used in a PISN which supports the supplementary services specified in this International Standard.
43、This means that, to claim conformance, a stage 3 standard is required to be adequate for the support of those aspects of clauses 6, 7, 8 and 9 (stage 1) and clause 10 (stage 2) which are relevant to the interface or equipment to which the stage 3 standard applies.A stage 3 standard for SS-CFU shall
44、support clauses 6 and 10 respectively.A stage 3 standard for SS-CFB shall support clauses 7 and 10 respectively.A stage 3 standard for SS-CFNR shall support clauses 8 and 10 respectively.A stage 3 standard for SS-CD shall support clauses 9 and 10 respectively. 3 Normative references ISO/IEC 11571:19
