18、-20:1995(E) 0 ISO/IEC Introduction This International Standardized Profile (ISP) is defined in accordance with the principles specified by ISO/IEC Technical Report 10000, “Information technology - Framework and taxonomy of International Standardized Profiles”. The context of Functional Standardizati
19、on is one area in the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, and registration mechanisms. A profile defines a combination of base standards that collectively perform a specific well-defined IT function. Profiles standardize the use
20、 of options and other variations in the base standards, and provide a base for the development of uniform, internationally recognized 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
21、most important roles for an ISP is to serve as the basis for the development (by organizations other than IS0 and IEC) of internationally 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. IS
22、O/IEC ISP 10609 consists of several parts of which this is part 20. This part of ISO/IEC ISP 10609 provides information on the structure and relationship of the ISDN based profile parts to each other and to other parts of ISO/IEC ISP 10609. There are further parts which specify profile requirements
23、that are subnetwork-independent or specific to particular types of subnetwork. In addition, for each individual profile there is a part of ISO/IEC ISP 10609 which identifies the specific requirements of that profile, making reference to appropriate material from parts 2 or 3, and from the subnetwork
24、 dependent parts of ISO/IEC ISP 10609. vi Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/18/2007 19:41:55 MDTNo reproduction or networking permitted without license from IHS -,-,- INTER

26、roup profiles for OS1 usage of ISDN 1 Scope 1.1 General ISO/IEC ISP 10609 is applicable to end systems concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OS1 standards, which collectively provide the connection-mode Transport Service using t
27、he connection-mode Network Service. This part of ISO/IEC ISP 10609 provides an overview of the multi-part structure for the ISDN TA profiles (which provide the Connection-mode Transport Service (COTS) using the Connectionless-mode Network Service (CLNS) and for the ISDN TC and TD profiles (which pro
28、vide the Connection-mode Transport Service (COTS) using the Connection-mode Network Service (CONS). 1.2 Position within the taxonomy This part of ISO/IEC ISP 10609 covers the taxonomy elements using an ISDN subnetwork with Transport Groups TA, TC and TD as described in the ISO/IEC TR 10000-2. In par
29、ticular, it provides an overview and description of a generalized multi-part structure covering the following ISDN ISPs: . Tx1131,Tx1231,Tx4111,Tx4211,Tx4311q,Tx4321qandTx4331(Tx=TA,TCandTDandq=lor 2). . TA = COTS over CLNS (to be developed) . TC = COTS over CONS with Mandatory Transport Protocol Cl

Figure 2 -Scenario of applicability of the COTS/CONS and COTSICLNS TX profiles Five of these access scenarios (i.e., TX 113 1, TX 123 1, TX 43 1 lq, TX 4321q and TX 433 1) are defined in CCITT Recommendations X.31 and X.612, and lSO/IEC 9574. The two remote access to DTE scenarios (Le., TX 4111 an
37、d TX 4211) are defined in ISO/IEC 9574/DAM 1 and draft revision of CCITT Recommendation X.612 (but not described in CCITT Recommendations X.3 1). Profiles TX 43 11 q and TX 432 1 q are further sub-classified by use of a fifth digit “4” (q = 1 or 2) depending on the need for using the signaling proto
38、col Q.93 1 (e.g., for TX 431 lq, the fifth digit “1” in TX 43111 represents no need for the use of Q.93 1 whereas the fifth digit “2” in TX 43 112 represents the need for the use of the signaling protocol Q.93 1). 2 Copyright International Organization for Standardization Provided by IHS under licen
