Defines the signalling protocol for supporting the Message Waiting Indication supplementary service (SS-MWI) at the Q reference point between Private Integrated Services Network Exchanges (PINXs) connected within a Private Integrated Services Network (PISN). This service permits a Served User to be sent a Message Waiting Indication and also the cancellation of this Message Waiting Indication.
