44、ized 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 organization to deal with particular fields of technical activity. ISO and IEC technical comm
45、ittees 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. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Internation
46、al Standards are drafted in accordance with the rules given in the ISO/IEC Directives, 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. Pu
47、blication 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 document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all
48、such patent rights. ISO/IEC 13873 was prepared by ECMA (as ECMA-174) 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. This second edition cancels and replaces
49、the first edition (ISO/IEC 13873:1995), which has been technically revised. ISO/IEC 13873:2003(E)vi ISO/IEC 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 Standards for Open Systems Interconnection as defined by ISO/IEC.
