Defines the signalling protocol for supporting the Call Completion supplementary services at the Q reference point between Private Integrated Network Exchanges (PINXs) connected within a Private Integrated Services Network (PISN). These supplementary services consist of Completion of Calls to Busy Subscribers (SS-CCBS) and completion of Calls on No Reply (SS-CCNR).
