PRIVATE INTEGRATED SERVICES NETWORK (PISN); MAPPING FUNCTIONS FOR THE EMPLOYMENT OF 64 KBIT/S CIRCUIT MODE CONNECTIONS WITH 16 KBIT/S SUB-MULTIPLEXING
出版：European Telecommunications Standards Institute
专家解读视频
This standard defines the mapping functions in exchanges of Private Integrated Services Networks (PISNs) required for the utilisation of scenarios in which 64 kbit/s circuit mode connections are sub-multiplexed into 4 x 64 kbit/s channels for carrying inter-PINX signalling and user information.
