Abstract

This International Standard specifies the mapping functions for a pair of on-demand inter-PINX connections using a circuitmode basic service and the supplementary service User-to-User Signalling (service 3) of a public ISDN at the same time.In order to connect a Private Integrated Services Network Exchange (PINX) to another PINX, mapping functions are requiredto adapt the specific interfaces at the C reference point to the application at the Q reference point. As such, mapping functionsprovide for physical adaptation to the interface at the C reference point. Mapping functions also provide for the mapping ofuser channels and signalling information at the Q reference point to the appropriate channels or timeslots at the C referencepoint.The C and Q reference points are defined in ISO/IEC 11579-1.At the Q reference point the mappings provide a 64 kbit/s service for user channels and a packet mode service for thesignalling channel. Bearer conditioning is outside the scope of this International Standard, except for providing the layer 2 forthe signalling channel at the Q reference point.Scenario management is outside the scope of this International Standard.This International Standard is applicable to PINXs which can be interconnected to form a Private Integrated Services Network(PISN) and which support signalling protocols at the Q reference point.
