CAN/CSA-ISO/IEC ISP 10609-33-99 (R2008)

This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10609-33:1995. 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 TC4211. The TC4211 profile is in the TC Group which supports Transport protocol classes 0 and 2. 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: TC4211 Connection-mode Transport Service over connection-mode Network Service - ISDN circuit-mode service, B-channel - X.25 DTE to DTE operation 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 TC4211 profile is applicable.
