National bodies th

26、at 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 committees collaborate in fields of mutual interest. Other intern

27、ational organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. In the field of information technology, ISO and IEC have established a joint te

28、chnical committee, ISO/IEC JTC 1. 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. Attention is drawn to the possibil

29、ity 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. International Standard ISO/IEC 11574 was prepared by ECMA (as ECMA-142) and was adopted, under a special “fast-tr

30、ack 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 11574:1994), which has been technically revised. Annexes A and B form a normative p

31、art of this International Standard. Annexes C and D are for information only.ISO/IEC 11574:2000(E) ISO/IEC 2000 All rights reserved vii Introduction This International Standard is one of a series of standards defining services and signalling protocols applicable to Private Integrated Services Networ

32、ks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This International Standard contains specifications of basic services. This International Standard is based upon the practi

33、cal experience of ECMA member companies and the results of their active and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus.INTERNATIONAL STANDARD ISO/IEC 11574:2000(E)

34、 ISO/IEC 2000 All rights reserved 1 Information technology Telecommunications and information exchange between systems Private Integrated Services Network Circuit-mode 64 kbit/s bearer services Service description, functional capabilities and information flows Section 1: General 1S c o p e This Inte

35、rnational Standard specifies the service description and control aspects, including functional capabilities and information flows, of standardised circuit-mode bearer services which may be supported by a Private Integrated Services Network (PISN). This International Standard includes the following b

36、asic services: Circuit-mode 64 kbit/s unrestricted 8 kHz structured bearer service category; Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for speech information transfer; Circuit-mode 64 kbit/s 8 kHz structured bearer service category usable for 3,1 kHz audio information tr

37、ansfer. A PISN shall support at least one of the above three bearer services to conform with this International Standard. The scope of this International Standard does not include: the negotiation of service at call establishment time, the change of service during a call, and unidirectional services

38、. This International Standard includes optional procedures for the provision of functions equivalent to the following public ISDN supplementary services: Subaddress and Multiple Subscriber Number. NOTE 1 - Supplementary services and other bearer services which can be used in conjunction with 64 kbit

39、/s circuit switched bearer services specified in this International Standard are dealt with in other standards. NOTE 2 - Service specifications are based on information concerning the corresponding public ISDN service available at the time of publication of this International Standard. NOTE 3 - ITU-

40、T treat Subaddressing and Multiple Subscriber Number as supplementary services. NOTE 4 - The use of the Direct Dial In supplementary service of a public ISDN for calls incoming to a PISN from a public ISDN is regarded as part of the basic services in a PISN. NOTE 5 - The use of the Calling Line Iden

41、tification Presentation and Connected Line Identification Presentation supplementary services of a public ISDN for obtaining the Originating Number or the Connected Number of a call from or to a public ISDN is regarded as part of the basic services in a PISN. NOTE 6 - The provision (either explicitl

42、y or implicitly) by the user to the network, of its own number (Originating Number or Connected Number), and the provision of an Originating Number or a Connected Number by a PISN to another network is a part of the basic services in a PISN and not a part of the Calling Line Identification Presentat

43、ion and Connected Line Identification Presentation supplementary services. Those supplementary services are concerned only with the presentation of the number from the network to the served PISN user. 2 Normative references The following normative documents contain provisions which, through referenc
