Open Systems Interconnection - Protocol for providing the connectionless-mode network service - Part 3: Provision of the underlying service by an X.25 subnetwork; identical with ISO/IEC 8473-3:1995
The document specifies the way in which the underlying service assumed by the protocol defined by ISO/IEC 8473-1 is provided by a subnetwork that conforms to CCITT X.25 through the operation of a Subnetwork Dependent Convergence Function (SNDCF). DIN ISO/IEC 8473-3 also provides the PICS proforma for this protocol.
