Abstract

A communications wiring system includes a communications network interface device for routing a plurality of source signals between respective ones of a plurality of types of electrical sources and a number of reconfigurable outlet assemblies. Each reconfigurable outlet assembly selectively establishes electrical connection with predetermined ones of the electrical sources, via a cable. The communications network interface device receives and splits the source signals into a predetermined number of subsignals which are routed to respective reconfigurable outlet assemblies. Each reconfigurable outlet assembly includes an outlet and a number of interchangeable electrical connectors, such as modular jacks, adapted to be removably mounted to the outlet for establishing electrical connection with a predetermined electrical source. In order to establish electrical connection with a different electrical source, a first electrical connector can be removed and a second electrical connector can be inserted therein. Accordingly, the communications wiring system of the present invention can be readily reconfigured by interchanging the electrical connectors to establish electrical connection with different electrical sources without rewiring.
