Publication date:   May 27, 1993

Scope

Specifies the method by which a network-layer interworking unit (IWU) uses the X.25 packet layer protocol to support the OSI connection-mode network service. The specification is expressed in terms of a mapping between the network internal layer service defined in ISO/IEC 10028 and the virtual call and permanent virtual circuit services of the X.25 packet layer protocol. Provides the PICS (Protocol Implementation Conformance Statement) proforma in compliance with the relevant requirements, and in accordance with the relevant guidance, given in ISO/IEC 9646-2.
