ABSTRACT:
A digital multiplexer for PCM voice communication is disclosed which operates to multiplex PCM voice channels on DS1, DS1C and DS2 digital transmission lines into one or more DS3 transmission lines and vice versa. On one side of the multiplexer are a number of terminals for connection to the low speed transmission lines. These terminals may be divided into "first terminals" adapted for connection to the incoming branch lines of the low speed (DS0, DS1, DS1C., DS2), duplex PCM highways and "second terminals" adapted for connection to the outgoing branch lines of the respective low speed, duplex PCM highways. On the opposite side of the system are a second set of terminals for connection to the high speed transmission lines. These terminals may be divided into "third terminals" adapted for connection to the incoming branch lines of the respective high speed (DS3), duplex PCM highways and "fourth terminals" adapted for connection to the outgoing branch lines of the respective high speed, duplex PCM highways. A bus network is arranged within the system for routing both digital data (voice samples) and destination or origination addresses throughout the system. The multiplexer operates to route each PCM voice sample received on any voice channel at a first or third terminal to any other PCM voice channel for outgoing transmission at a second or fourth terminal.
