This part of ISO/IEC ISP 10609 is applicable to end systems concemed 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. 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. This part of ISO/IEC ISP 10609 specifies the definition of Profiles TE1111/TE1121. The TE1111/TE1121 profiles are in the TE group which uses Transport protocol class 2. 1.2 Position of Profiles within the Taxonomy This part of ISO/IEC ISP 10609 covers the taxonomy elements identified as "TB, TC, TD and TE" in the "Directory of Profiles and ISPs" contained in ISO/IEC/TR 10000-2. This part of ISO/IEC ISP 10609 specifies the definition ol Profiles TE1111/TE1121. These profies may be combined with any A-profile at the A/T boundary. 1.3 Scenario Figure 1 illustrates the end system configurations to which TE1111/TE1121 profiles are applicable. TE1111/TE1121 Reference End System Remote End System PSDN ** TE1111/TE1121 Reference Point ** Other network equipment - none - OSI relays - other equipment Figure 1 - Scenario of Applicability of the TE1111/TE1121 Profiles This part of ISO/IEC ISP 10609 specifies the required functions from the supporting protocol stack shown in tables 1 and 2. Table 1 - TE1111 Profile protocol stack for end system Transport Layer ISO/IEC 8073 Network Layer ISO/IEC 8208, ISO 8878 Data Link Layer ISO 7776 Physical Layer X.25 dedicated access via PSTN Table 2 - TE1121 Profile protocol stack for end system Transport Layer ISO/IEC 8073 Network Layer ISO/IEC 8208, ISO 8878 Data Link Layer ISO 7776 Physical Layer X.25 dedicated access via Digital Data Circuit This part of ISO/IEC ISP 10609 does not specify the required functions for relays.
