scope:

This ETS 2nd part of describes the conformance testing of APPLI/COM Programmable Communication Interfaces (PCIs) that claim conformance to ETS 300 243-1 [1], which in turn endorses CCITT Recommendation T.611 [2], with certain ETSI modifications.

The aim of this Part of the ETS is to define conformance tests and methods which ensure, when applied, that:

- a conforming implementation of a Local Application (LA) can work together with a conforming implementation of a Communication Application (CA). The LA can coexist, access and communicate with the CA from within the Terminal Equipment (TE) of the LA;

- a conforming implementation of a CA offers and carries out the functionality and features declared and covered by one of the functional classes defined by CCITT Recommendation T.611 [2].

The intention of this Part of the ETS is to test one LA to one CA relation.

When many LAs are present within the same TE, many LAs to one CA relation, testing of the LAs need to handle one LA at a time. To ensure conformance in the case of a many LA to one CA relationship, test cases are provided exclusively for testing the CA conformance with respect to multiple LAs.

When many CAs are accessible from within the same TE, the testing of the CAs needs to be carried out one CA at a time. No special test cases are provided for the case of multiple CAs in the same equipment.
