19、cified by ISO/IEC Technical Report 10000, “Information Technology - Framework and taxonomy of International Standardized Profiles”. The context of Functional Standardization is one area in the overall field of Infor- mation Technology (IT) standardization activities, covering base standards, profile
20、s, 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 rec
21、ognized 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 intern
22、ationally 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 10609 consists of several parts of which this is part 38. This part of ISO/IEC ISP 10609 identifies the specific requi
23、rements of TC4331, making reference to appropriate material from part 1 and from the subnetwork dependent parts of ISO/IEC ISP 10609. There are also some parts which specify subnetwork-dependent and media-dependent requirements, and the other parts which specifies the profile requirements that are s
24、ubnetwork-independent. vii Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/22/2007 22:09:50 MDTNo reproduction or networking permitted without license from IHS -,-,- INTERNATIONAL STANDA

26、nd systems concerned with operating in the Open Systems Interconnection (OSI) environment. 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 specifies the definition
27、of Profile TC4331. The TC4331 profile is in the TC group which supports Transport protocol classes 0 and 2. 1.2 Position of Profiles within the Taxonomy The taxonomy of profiles is defined in ISO/ICE TR 10000-2. This part of ISO/IEC ISP 10609 defines the profile: TC433 1 Connection-mode Transport Se
28、rvice over Connection-mode Network Service over ISDN - Packet mode service - B-channel demand access - Virtual Call (VC) This profile may be combined with any A-profile at the A/T boundary.

At layer 3, CCITT Q.931 signalling procedures are used on the D-channel, and ISO/IEC 8208 packet layer protocol is used in DTE/DCE mode on the B-channel.

35、 without license from IHS -,-,- 0 ISOAEC ISOAEC ISP 10609-38:1995(E) The reference end system implements two protocol pillars below layer 4. One pillar is used over the ISDN D-channel for establishment, maintaining and clearing B-channel access connection. The other is used over the B-channel(s) for
36、 establishing, maintaining and clearing virtual calls, and for the information transfer itself. In making a call, Network Service connection establishment is a multi-stage process, first stage is the establishment of B-channel access connection using D-channel call control procedures, the next is es
37、tablishment of IS0 7776 Data Link layer, and finally the virtual is established. In receiving a call, Network Service connection establishment is a multi-stage process; the first stage is the channel selection and establishment of B-channel access connection (if not established) using D-channel call
38、 control procedure, the next is the establishment of the IS0 7776 Data Link layer (if not established), finally the virtual call is established. Network Service connection release is also multi-stage process; the first stage being the release of the virtual call. If the associated B-channel connecti
39、on does not currently support any other Network Service connections, the system may release the IS0 7776 Data Link layer connection, and may then release the B-channel connection using the D-channel signalling procedure in conformity with CCITT Q.931. 2 Normative references The following documents c
