National bodies that are members of ISO or IEC participate in the devel
18、opment 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-governmen
19、tal, 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 task of th
20、e 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 a vote. A
21、ttention 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 14846 was prepared by ECMA (as ECMA-203) and was adopted, under a special “fast-track
22、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 14846:1996), which has been technically revised. ISO/IEC 14846:2003(E) vi ISO/IEC 2003
23、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 framework of International Stand
24、ards 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 Call Intrusion supplementary service. The protocol defined in this International Standard forms part of the PSS1 protocol (inf
