Abstract
A multipoint data communication system is disclosed for transmitting data to and from a plurality of communicating devices via an interconnecting cable. This interconnecting drop cable couples a transceiver unit to a communicating device, such as a personal computer, workstation, printer, or the like. The drop cable herein has only two twisted, jointly shielded, pairs of wires to transmit the three signals (transmit, receive, collision) and power. AC differences in the pairs constitute the third, phantom, signal channel. DC differences in the pairs provide the power source for transceiver operations. This cable is considerably less expensive than the industry standard cable.
