Abstract
A data communication system is provided in which the data handling capacity of the system is doubled. The data in the system travels on a single wire in both directions simultaneously. Each pair of terminals associated with the communication system is interfaced with the single wire by a repeater. The repeater includes first and second directional couplers for coupling data signals from the repeater to the wire in the one direction and in the opposite direction, respectively, without substantial signal interference with signals being received by the repeater on the same wire. A wrap control function is included in the repeater which allows data signals to be placed on the wire going in the opposite direction from the received signals.
