The apparatus coupled with an electrical cable includes at least one active wire, one neutral wire and one ground wire, the transmitter and the receiver each including a coupling circuit for coupling the apparatus to the residential electrical cables. The coupling circuit has a first transformer and a second transformer, the first transformer including a center tap, receive wire pairs and transmit wire pairs each being formed from at least two of the active wire, the neutral wire, the ground wire and the midpoint. The processor dynamically switches a coupling of the receiver and the transmitter respectively between the receive wire pairs and the transmit wire pairs.
