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 an X.25 packet-switched data network by a dedicated (permanent) access line and using switched virtual calls. The Directory of Profiles and ISPs in ISO/IEC TR 10000 identifies this TA profile configuration as TA1111 or TA1121. The complete set of requirements for TA11n1 consists of the requirements specified in ISO/IEC ISP 10608-1 and ISO/IEC ISP 10608-5.
1.2
Position of Profile Within the Taxonomy ISO/IEC ISP 10608-5 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.
This clause specifies requirements for the profile identified in ISO/IEC TR 10000 as TA11n1, Connection-mode Transport Service provided over the Connectionless-mode Network Service through dedicated (permanent) access to an X.25 packet-switched data network using virtual calls.
Figure 1 illustrates the standards which comprise the TA1111 and TA1121 profiles.
1.3
Scenario Figure 2 illustrates the configuration of systems to which TA11n1 is applicable.
