Information technology — Telecommunications and information exchange between systems — X.25 DTE conformance testing — Part 3: Packet layer conformance test suite

This part of ISO/IEC 8882 specifies a set of abstract tests for verifying that the implementation of X.25 protocols for use by Data

Terminal Equipment (DTE), conforms to the requirements of International Standards that specify those protocols.

Testing of a DCE is not subject of this test suite. Testing of a DTE in DCE mode is covered in test group 28 of this test suite

a) specifies a PIXIT proforma;

b) describes the relationship of the PICS to the test suite,

c) describes the relationship of the PIXIT to the test suite,

d) specifies a set of abstract tests using TTCN Graphical notation.

This part of ISO/IEC 8882 defines the testing of a DTE operating at the packet layer designed to access a public or private

packet-switched network conforming to CCITT respectively ITU-T Recommendation X.25 (1980, 1984, 1988, 1993) or another

DTE conforming to ISO 8208. The specification of test cases in executable/machine processable TTCN is outside the scope of

this part of ISO/IEC 8882.
