ISO/IEC 8882 defines the testing of a DTE operating at the Data Link Layer and at the Packet Layer when accessing by means of a dedicated path connection, switched or permanent, a public or private packet-switched network conforming to CITT Recommendations X.25 or another DTE conforming to ISO/IEC 7776 and ISO/IEC 8208.

The tests will test the conformance of an implementation by observing its external behavior. The conformance tests will not test the DTE performance characteristics, the diagnostic and maintenance functions, the correctness of the protocol itself, or DTE internal implementation, or the full capabilities as stated in the PICS.

This part of ISO/IEC 8882

— provides a general introduction;

— refers to those applicable International Standards;

— defines terms applicable to X.25-DTE conformance testing;

— states the test case derivation and description: and

— states the test methodology

ISO/IEC 8882-1 contains no statement of conformance. Specific statements of conformance are given in ISO/IEC 8882-2 and ISO/IEC 8882-3
