14、13-16:1995(E) Introduction ISO/IEC ISP 106 13 is defined in accordance with the principles specified by ISO/IEC Technical Report 10000. The context of Functional Standardization is one area in the overall field of Information Technology (IT) standardization activities, covering base standards, profi
15、les, and registration mechanisms. A profile defines a combination of base standards that collectively perform a specific well-defined IT function. Profiles standardize the use of options and other variations in the base standards, and provide a basis for the development of uniform, internationally r
16、ecognized system tests. ISPs are produced not simply to legitimize a particular choice of base standards and options, but to promote real system interoperability. One of the most important roles for an ISP is to serve as the basis for the development (by organizations other than IS0 and IEC) of inte
17、rnationally recognized test methods. The development and widespread acceptance of tests based on this and other ISPs is crucial to the successful realization of this goal. ISO/IEC ISP 106 13 consists of several parts of which this is part 16. ISO/IEC ISP 10613-l specifies the profile requirements th
18、at are subnetwork-independent. There are further parts which specify subnetwork-dependent and media-dependent requirements. In addition, for each individual profile there is a part of ISO/IEC ISP 10613 which identifies the specific requirements of that profile, making reference to appropriate materi
19、al from part 1 and from the subnetwork-dependent parts of lSO/IEC ISP 10613. This part of ISO/IEC ISP 10613 is the one which identifies the specific requirements for profile RA53.112 1.

23、licable to interworking units concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OS1 base standards that collectively provide a network-relay function for the connectionless-mode Network Service. This part of ISO/IEC ISP 106 13 defines the R
24、A53.112 1 profile, which is applicable to interworking units operating between Token Ring LAN subnetworks and PSDNs using virtual calls over a digital data circuit/CSDN leased line permanent access. 1.2 Position within the taxonomy The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part
25、 of ISO/IEC ISP 106 13 defines the profile RA53.1121 Relaying the Connectionless-mode Network Service between Token Ring LAN subnetworks and PSDNs using virtual calls over a digital data circuit/CSDN leased line permanent access. 1 Copyright International Organization for Standardization Provided by

29、with End Systems implementing profiles from the TA or UA groups, provided that suitable relays are in place in the case of those members of these groups which relate to different elements of the subnetwork taxonomy.

All documents are subject to revision, and parties to agreements based on this part of ISO/IEC ISP 10613 are warne
33、d against automatically applying any more recent editions of the documents listed below, since the nature of references made by ISPs to such documents is that they may be specific to a particular edition. Members of IEC and IS0 maintain registers of currently valid International Standards and ISPs,
34、and KU-T maintains published editions of its current Recommendations. NOTE - IS0 7776:1986, IS0 8473:1988 and IS0 8802-2:1989 have been superseded by new editions (ISO/IEC 7776:1995, ISO/IEC 8473-1:1994 and ISO/lEC 8802-2:1994 respectively) incorporating all of the previous amendments and corrigenda
35、. However, when this part of ISO/IEC ISP 10613 was under development, the previous editions were valid and this part of ISOlIEC ISP 10613 is therefore based on these editions.
