7、ardization, in accordance with the principles specified by ISO/IEC TR 10000-1 :1990. The context of Functional Standardization is one part of the overall field of Information Technology (IT) standardization activities, covering base standards, profiles, and registration mechanisms. A profile defines
8、 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 International Standards, and provide a basis for the development of uniform, internationally recognized system tests. One of the mo
9、st 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. ISPs are produced not simply to “legitimate“ a particular choice of base standards and options, but to promote real system intero
10、perability. The development and widespread acceptance of tests based on this and other ISPs is crucial to the successful realization of this goal. ISOIIEC ISP 10609 consists of several parts, of which this is part 6. ISOIEC ISP 10609-1, ISO/IEC 10609- 2, ISO/IEC 10609-3 and ISO/IEC ISP 10609-4 speci
11、fy subneiwork-type independent requirements for Group TB, TC, TD and TE profiles, respectively.

14、1) environment. It specifies a combination of OS1 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 a
15、ny type of subnetwork from which the standardized connection-mode Network Service can be made available. This part of ISOAEC ISP 10609 specifies the definition of Profiles TC1 11 lTTC1121. The TC1 11 1/TC1121 are profiles in the TC group which uses Transport protocol classes O and 2. 1.2 Position of
