Scope, purpose, and field of application

This standard is identical to ITU-T Recommendation I.365.1, Frame relaying service specific convergence sublayer (FR-SSCS), from the International Telecommunication Union.

This standard specifies the Frame Relaying Service Specific Convergence Sublayer (FRSSCS). The FR-SSCS is located in the upper part of the ATM Adaptation Layer on top of the Common Part Convergence Sublayer (CPCS) of AAL type 5, as specified in ITU-T (formerly CCITT) Recommendation I.363, section 6. The FR-SSCS is used at the B-ISDN TE to emulate the Frame Relaying Bearer Service (FRBS) in B-ISDN. It is also used for interworking between a B-ISDN and a Frame Relaying Network.
