Annex A (informative) Conformance Testing Summary Matrix

Defines an abstract test suite for testing the conformance of the Data Link Layer of an IUT with respect to the CCITT Recommendation X.25 (1980, 1984) or ISO 7776. Excludes the testing of the LAP procedures given in the CCITT Recommendations. Includes definitions and abbreviations, detailed annexes, a glossary and an index.
