19、SO/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, profiles, and regi
20、stration 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 recognized sys
21、tem 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 internationally r
22、ecognized 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 37. This part of ISO/IEC ISP 10609 identifies the specific requirements of
23、TC43212, 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 subnetwork
24、-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 22:03:33 MDTNo reproduction or networking permitted without license from IHS -,-,- INTERNATIONAL STANDARDIZED PR

26、ems 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 of Prof
27、ile TC43212. The TC43212 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/IEC TR 10000-2.

However, ITU-T ma
29、y define a procedure that would allow an ISDN terminal to have a semi-permanent connection set up in support of permanent B- channel. At that time, amendments to this profile may be necessary. This profile uses the term “permanent”. This profile may be combined with any A-profile at the A/T boundary

At layer 2, CCITT Q.921 provides the LAPD Data Li
36、nk procedures for the D-channel and IS0 7776 provides the LAPB Data Link procedures for the B-channel. 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. The provisions of ISO/IEC 8878 apply with r
37、egard to the mapping of the CONS primitives and parameters to and from the elements of the ISO/IEC 8208 packet layer protocol. In receiving a call, the reference end system implements two protocol pillars below layer 4. One pillar is used over the ISDN D-channel for channel selection. The other is u
38、sed over the B-channel for establishing, maintaining and clearing virtual calls, and for information transfer itself. In making a call, it implements only latter protocol. In making a call, Network Service connection establishment is a single stage process, involving the establishment of a virtual c
39、all. (But, the Data Link layer connection needs to be established by user or PH.) In receiving a call, Network Service connection establishment is a multi-stage process; the first stage is the channel selection using D-channel call control procedure, the next is the establishment of the IS0 7776 Dat
40、a Link layer over the B- channel (if not already established), finally the virtual call is established. Network Service connection release is a single stage process, involving the release of a virtual call. 2 Normative references The following documents contain provisions which, through reference in
