This part of ISO/IEC8473 specifies the way in which the underlying service assumed by the protocol defined by ISO/IEC8473-1 is provided by a subnetwork that conforms to ISO/IEC8802 through the operation of a subnetwork dependent convergence function (SNDCF) as described in ISO/IEC8648. The SNDCF specified by this part of ISO/IEC8473 may be used with any ISO/IEC8802 compliant subnetwork that provides the logical link control sublayer interface service defined by ISO/IEC8802-2.
This part of ISO/IEC8473 also provides the PICS proforma for this protocol, in compliance with the relevant requirements, and in accordance with the relevant guidance, given in ISO/IEC9646-1.
