ABSTRACT:
A multiplexing communication system for combining several asynchronous digital signals 151, 156 into a single high-speed line 141 comprising synchronizing circuits 101, 106 on each on n input data lines, service information insertion circuits 180 on each of the n synchronized lines, an nBmB coder 130 utilizing a pulse stuffing circuit 170 for increasing the n synchronized signals to m synchronized signals, and a multiplexer 140 for converting the m synchronized signals into a single high speed output 141.
