National bodies that are members of ISO or IEC participate in
41、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, governmental and non-
42、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 Directives, Part 2. The main t
43、ask 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 national bodies casting
44、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 15052 was prepared by ECMA (as ECMA-214) and was adopted, under a special “fa
45、st-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 15052:1997), which has been technically revised. ISO/IEC 15052:2003(E)vi ISO/I
46、EC 2003 All rights reservedIntroductionThis International Standard is one of a series of Standards defining services and signalling protocols applicable to PrivateIntegrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the frameworkof International S
47、tandards for Open Systems Interconnection as defined by ISO/IEC.This International Standard specifies the signalling protocol for use at the Q reference point in support of the Recallsupplementary service. The protocol defined in this International Standard forms part of the PSS1 protocol (informall
48、y knownas QSIG).This International Standard is based upon the practical experience of ECMA member companies and the results of their activeand continuous participation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardizationbodies. It represents a pragmatic and
49、widely based consensus. ISO/IEC 2003 All rights reserved 11ScopeThis International Standard specifies the signalling protocol for the support of Recall supplementary service (SS-RE) at the Qreference point between Private Integrated services Network eXchanges (PINXs) connected together within Private IntegratedServices Network (PISN).SS-RE is a supplementary service which provides for the re-direction of a transferred call back to the served user if the ca
