Abstract
A cable system for supplying information contained in a plurality of parallel signals on a first set of plug contacts of a first plug at a modem, to a second set of plug contacts of a second plug at a CPU, a remote terminal or the like, without requiring use of a large, expensive multiwire cable containing a wire for each signal. The cable system comprises a transmission line and two connector plug assemblies connected to opposite ends of the transmission line, one of the plug assemblies being adapted to mate with the plug contacts of the plug at the modem and the other to mate with the plug contacts at the CPU or remote terminal. Each plug assembly contains a parallel-to-serial converter and a serial-to-parallel converter; each parallel-to-serial converter samples the parallel signals at its associated plug to produce, on a corresponding twisted pair of wires in the cable, time-multiplexed serial signal representing the parallel signals, and each serial-to-parallel converter converts its received serial signal back to parallel and applies it to its associated plug contacts. Two twisted-pair lines are then sufficient to transmit a large number of signals in both directions.
