Abstract:
A method for use by a transceiver to communicate over a wire in a group of wires comprising:receiving communications over a first wire; transmitting over the first wire a communication signal that electromagnetically couples to a second wire to produce an electromagnetically coupled signal on the second wire; conveying a message, by the electromagnetically coupled signal, that induces a response from a second transceiver connected to the second wire; detecting interference on the second wire due to the communications received over the first wire, wherein the transmitting of the communication signal occurs in response to detecting the interference; ceasing transmission of the communication signal if the detected interference is below a predetermined threshold; and transmitting a second communication signal over the first wire, in response to detecting that the interference is below the predetermined threshold, to produce a second electromagnetically coupled signal on the second wire that conveys a new message to the second transceiver.
