1. Scope

1.1

General This part of ISO/IEC ISP 10608 specifies subnetwork-type dependent requirements for end system operation when the end system is attached to a carrier-sense multiple access with collision detection (CSMA/CD) local area network. The Directory of Profiles and ISPs in ISO TR 10000 identifies this TA profile configuration as TA51. The complete set of requirements for TA51 consists of the requirements specified in ISO/IEC ISP 10608-1 and ISO/IEC ISP 10608-2.

1.2

Position of Profile Within the Taxonomy ISO/IEC ISP 10608 covers the taxonomy elements identified as ""TA"" in the Directory of Profiles and ISPs contained in ISO/IEC TR 10000-2. These elements constitute Transport profiles, group A: Connection-mode Transport Service over Connectionless-mode Network Service.

1.3

Scenario This clause specifies requirements for the profile identified in ISO/IEC TR 10000 as TA51, Connection-mode Transport Service provided over the Connectionless-mode Network Service on a CSMA/CD LAN.

Figure 1 illustrates the standards which comprise the TA51 profile.

Figure 2 illustrates the configuration of systems to which TA51 is applicable.
