This part of ISO/IEC ISP 10609 is applicable to end systems concerned with operating in the Open Systems Interconnection(OSI) environment. lt 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 is applicable to the provision of the connection-mode Transport Service in end systems attached to any type of subnetwork from which the standardized connection-mode Network Service can be made available.
Profiles of the Connection-mode Transport Service over Connection-mode Network Service are grouped according to their required support of transport protocol class(es).
Group TB: Includes transport protocol classes 0, 2 and 4 Group TC: Includes transport protocol classes 0 and 2 Group TD: Includes transport protocol class 0 Group TE: Includes transport protocol class 2. This part of ISOIIEC ISP 10609 specifies the subnetwork-type independent requirements for Group TC.
