Information technology. Telecommunications and information exchange between systems. Provision of the connection-mode Network internal layer service by intermediate systems using ISO/IEC 8208, the X.25 Packet Layer Protocol Ingestion-build-95349 BS 4267-4 is the fourth1 Scope This International Standard specifies the method by which a Network layer interworking unit (IWU) uses the X. 25 packet layer protocol specified in ISO IEC 8208 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 (VC) and Permanent Virtual Circuit (PVC) services of the X. 25 packet layer protocol.
