This International Standard specifies the mapping functions for a pair of on-demand inter-PINX connections using a circuit
mode 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 required
to adapt the specific interfaces…
