Disclosed is an apparatus and method for communicating over an electrically conductive line having a plurality of power line phases between a first device having a single receiver and plurality of distal devices. The power line phases are adapted to deliver an alternating electrical current. Each of the distal devices are adapted to communicate with the first device over a single phase through a modulated carrier signal at a communication frequency. The apparatus comprises a plurality of unique coupling phases for coupling to a corresponding power line phase adapted to receive a frequency band having the modulated carrier signal from each of the plurality of power line phases and a selective coupling circuit between each of the plurality of coupling phases. The method comprises receiving the modulated carrier signal from each of the plurality of power line phases, attenuating the frequency band from being received by another of said unique coupling phases.
