Information technology - International Standardized Profiles TB, TC, TD and Te - Connection-mode Transport Service over connection-mode Network Service - Part 42: Definition of profile TD4111
This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10609-42:1995. 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 OSI standards, which collectively provide the connection-mode Transport Service using the connection-mode Network Service. This part of ISO/IEC ISP 10609 defines the profile TD4111. The TD4111 profie is the TD Group which supports Transport protocol class 0. 1.2 Position within the taxonomy The taxonomy of OSI profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10609 defines the profile: TD4111 Connection-mode Transport Service over connection-mode Network Service - ISDN B-channel permanent service - X.25 DTE to DTE operation. NOTE - At time of publication of this part of ISO/IEC ISP 10609, there is no difference from a terminal point of view between "permament" and "semi-permanent" connections. However, ITU-T may define a procedure that would allow an ISDN terminal to have a semi-permanent connection in support of a 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. 1.3 Scenario Figure 1 illustrates the configuration of systems to which the TD4111 profile is applicable.
