CAN/CSA-ISO/IEC ISP 10609-14-99(R2003)

1. Scope1.1General This International Standardized Profile 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 TC53 profile which is applicable to the provision of the OSI connection-mode Transport Service using the OSI connection-mode Network Service in an End System attached to a Token Ring LAN subnetwork.1.2Position within the Taxonomy The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10609 defines the profile:TC53Connection-mode Transport Service over connection-mode Network Service over Token Ring LAN subnetworks.1.3Scenario Figure 1 illustrates the configurations of systems to which the TC53 profile is applicable.The TC53 profile specifies the required functions from the supporting protocol stack shown in figure 2.This profile does not specify the required functions for relays.
