National bodies that are members of ISO o

16、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,

17、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

18、s, 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 nat

19、ional 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) a

20、nd 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. Annexes A and B form a normative part of this International Standard. ISO/IEC 20161:2001(E) vi ISO/IEC 2001 All

21、 rights reservedIntroduction 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 Standards

22、 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 provi

23、ders. 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 b

24、ased consensus. INTERNATIONAL STANDARD ISO/IEC 20161:2001(E) ISO/IEC 2001 All rights reserved 1Information technology Telecommunications and information exchange between systems Private Integrated Services Network Use of QSIG at the C reference point between a PINX and an Interconnecting Network 1 S

25、cope This International Standard specifies the combination of base standards, together with the selection of appropriate options and parameter values, necessary to specify how QSIG / PSS1 can be used to provide digital signalling capabilities at interfaces at the C reference point between a Private

26、Integrated services Network eXchange (PINX) and an Interconnecting Network (ICN) to permit interoperability between equipment from different vendors and different public or private service providers. NOTE 1 - PINX in the sense of this International Standard is used in the meaning of a PINX directly

27、attached to the ICN. This International Standard is applicable to attached PINXs and Interconnecting Networks (ICN). This International Standard identifies the necessary or optional employment of particular functions, procedures and services when provided: - physical and electrical characteristics (

28、physical layer) of the interfaces to the transmission systems to be employed; - data link layer procedures; - network layer procedures; and - supplementary services and additional network features to meet specific corporate network user requirements. This International Standard states requirements u

29、pon attached PINXs and Interconnecting Network (ICN) implementations in order to achieve interoperability between equipment in PISNs serving as Corporate telecommunication Networks (CNs). NOTE 2 - Implementation of this International Standard does not preclude a manufacturer from offering other mean

30、s of interconnection. It also does not preclude a VPN service provider to offer basic call communications between a PINX and other networks like PSTN or ISDN. ISO/IEC TR 14475 specifies various access arrangements between a PINX and a public network where reference points C and T reside either at a

31、single or at separate interfaces. The scope of this International Standard is limited to cover the C reference point aspects at a separate interface. The current version of this International Standard does not intend to specify any gateway or end PINX requirements for the ICN side of the interface.

32、Therefore it typically uses the term “virtual transit PINX“ instead of Interconnecting Network (ICN). 2 Conformance A system conforms to this International Standard if it correctly performs all the mandatory capabilities defined in the requirement list (RL) (annex A) and the profile specific ICS (an

33、nex B). NOTE 3 - For the purpose of this International Standard capabilities marked as optional in the base standards may be mandatory or excluded. 3 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this Interna

34、tional Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply.
