scope:

This International Standard specifies the signalling protocol for the support of name identification supplementary services at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). The name identification supplementary services are Calling Name Identification Presentation (SS-CNIP) and Connected Name Identification Presentation (SS-CONP). Calling Name Identification Presentation (CNIP) is a supplementary service which is offered to the called user and which provides the name of the calling user (calling party name) to the called user. Connected Name Identification Presentation (CONP) is a supplementary service which is offered to the calling user and which provides to the calling user the following: - the name of the user who answers the call (connected party name); - optionally the name of the alerting user (called party name); - optionally the name of the called user who cannot be reached (busy party name). The supplementary service Calling/Connected Name Identification Restriction (CNIR) has no impact on the signalling at Q reference point.
