National bodies that are members of ISO

41、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 committees collaborate in fields of mutual interest. Other international organizations,

42、 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 Directiv

43、es, Part 3. 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 na

44、tional bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard 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 20161 was prepared by ECMA (as ECMA-318)

45、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.

The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standard

47、s for Open Systems Interconnection as defined by ISO/IEC. This International Standard specifies the functional profile for interconnecting Private Integrated services Network eXchanges (PINXs) to VPN service centers to permit interoperability between equipment from different vendors and service prov

48、iders. 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 regional standardization bodies. It represents a pragmatic and widely

49、based consensus.
