Device and method for communicating data signals through multiple power line conductors
First Claim
1. A device for communicating data through a power line cable that is connected to the internal wiring of one or more customer premises, wherein the cable is comprised of a first energized conductor and a second energized conductor, the device comprising:
- a first conductor coupled to the first energized conductor;
a second conductor coupled to the second energized conductor;
a first surge suppression circuit coupled to said first conductor;
a second surge suppression circuit coupled to said second conductor;
a first high pass filter coupled to said first conductor;
a second high pass filter coupled to said second conductor; and
a data signal source communicatively coupled to said first conductor and said second conductor to differentially communicate data signals to the first and second conductors.

Abstract
The present invention provides a device for providing communications through power lines comprised of multiple conductors by transmitting the data signals through a plurality of the conductors. One embodiment of the present invention may be comprised of a transmit circuit communicatively coupled to a first energized conductor for applying a first voltage signal representing the data to the first energized conductor; the transmit circuit being communicatively coupled to a second energized conductor for applying a second voltage signal representing the data to the second energized conductor; and wherein the second voltage signal is opposite in polarity to said first voltage signal.
