A circuit and supplemental power source connection scheme for a telecommunications modem transmission link are described. The supplemental power source is connectable at any point along a telecommunications wire, including the terminals of repeaters and remote terminals. The combiner circuit includes a diode bridge for ensuring the proper connection of externally connected high voltage power to internal circuitry of the power combiner. The combiner also includes a line polarity matching circuit that automatically configures to signally connect internal positive and negative voltage signals to corresponding positive and negative external signal lines on a telecommunications modem transmission link.

A multi-drop digital telephone loop uses point-to-point digital communication between a series of Add/drop units and a central office terminal to route telephone traffic to customers. The loop automatically detects and signals subscriber channel conflicts and also function in an auto-assign mode for automatically assigning subscriber channels. The loop may also be deployed in conjunction with a remote terminal located at a subscriber's residence or business.
