8、ternational Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular
9、 fields of technical activity. IS0 and IEC technical com- mittees collaborate in fields of mutual interest. Other international or- ganizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have establ
10、ished a joint technical committee, ISO/IEC JTC 1. In addition to developing International Standards, ISO/IEC JTC 1 has created a Special Group on Functional Standardization for the elaboration of International Stan- dardized Profiles. An International Standardized Profile is an internationally agree
11、d, harmonized document which identifies a standard or group of standards, together with options and parameters, necessary to accomplish a func- tion or set of functions. Draft International Standardized Profiles are circulated to national bod- ies for voting. Publication as an International Standard
12、ized Profile re- quires approval by at least 75 % of the national bodies casting a vote. International Standardized Profile ISO/IEC ISP 10609-4 was prepared with the collaboration of - OSI Asia-Oceania Workshop (AOW); - European Workshop for Open Systems (EWOS); - OSI Implementors Workshop (OIW) ISO

18、oduction This part of ISO/IEC ISP 10609 (International Standardized Profile) is defined within the context of Functional Standardization, in accordance with the principles specified by ISOIIEC TR 10000-l :1990. The context of Functional Standardization is one part of the overall field of Information
19、 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 of options and other variations in the base Inter
20、national Standards, and provide a basis for the development of uniform, internationally recognized system tests. 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 internationally recognized tests and test centres. lSP
21、s are produced not simply to “legitimate” a particular choice of base standards and options, but to promote real system interoperability. 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 10609 consists
22、of several parts, of which this is part 4. ISO/IEC ISP 10609-l) ISO/IEC 10609- 2, ISO/lEC 10609-3 and ISO/IEC ISP 10609-4 specify subnetwork-type independent requirements for Group TB, TC, TD and TE profiles, respectively.

25、B, TC, TD and TE - Connection-mode Transport Service over connection-mode Network Service - Part 4: Subnetwork-type independent requirements for Group TE 1 Scope This part of ISO/IEC ISP 10609 is applicable to end systems concerned with operating in the Open Systems lnterconnection(OSI) environment.
26、 It specifies a combination of OSI standards, which collectively provide the connection-mode Transport Service using the connection-mode Network Service. This part of ISO/IEC ISP 10609 is applicable to the provision of the connection-mode Transport Service in end systems attached to any type of subn
27、etwork from which the standardized connection-mode Network Senrice can be made available. Profiles of the Connection-mode Transport Service over Connection-mode Network Service are grouped according to their required support of transport protocol class(es).

38、d TSAP-ID field in a CR TPDU. 2) when necessary, transmitting a Calling TSAP-ID field in a CR TPDU that can convey any one of the Transport Selectors implemented by the system, d) if it claims to be capable of responding to a TC establishment attempt, be capable of 1) transmitting a Calling TSAP-ID
39、field in a CC TPDU. 2) when necessary, transmitting a Called TSAP-ID field in a CC TPDU that can convey any one of the Transport Selectors implemented by the system, e) be capable to configure the initial values of TSl and TS2 , if implemented. It is strongly recommended that a conformant system sho
40、uld implement and use TSl and TS2. 5.2.2 Dynamic conformance requirements a) TSAP-ID The implementation shall support remote TSAP-ID parameters of variable size up to and including 32 octets using any encoding and any value. Local T-selectors shall not exceed 32 octets in length. On receipt of a CR

The absence of the CC Calling TSAP-ID parameter on receipt indicates that the value of CC Calling TSAP-ID parameter is equivalent to the value of CR Calling
42、TSAP-ID parameter. The absence of the CC Called TSAP-ID parameter on receipt indicates that the value of CC Called TSAP-ID parameter is equivalent to the value of CR Called TSAP-ID parameter.
