Information technology - Telecommunications and information exchange between systems - Private Integ...
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…
Information technology - Telecommunications and information exchange between systems - Private Integ...
This International Standard defines the mapping functions in exchanges of Private Integrated Services Networks (PISNs)
required for the utilization of scenarios in which 64 kbit/s circuit mode connections are sub-multiplexed into 4 x 16 kbit/s
channels for carrying inter-PINX signalling and user information.
NOTE 1 - This International Standard has been prepared to meet the specific needs of an…
