Patent ID: 7729416

Claim:
An apparatus, comprising: a connector for providing a network connection via cabling utilizing wire pairs; and an interface device coupled to the connector, the interface device comprising: two transmit encoders, the two transmit encoders transmitting data and encoding the data with a pulse amplitude modulation (PAM); a first set of two hybrid canceller transceivers, the first set of two hybrid canceller transceivers receiving the encoded data from the two transmit encoders and transmitting the data as a signal across two of the wire pairs; a second set of two hybrid canceller transceivers, the second set of two hybrid canceller transceivers receiving the signal from the first set of two hybrid canceller transceivers; and two receive decoders, the two receive decoders receiving the signal from the second set of two hybrid canceller transceivers and decoding the signal back to data for further transmission; wherein the interface device is configured to establish at least a first communications link capable of transmitting data at a throughput of at least 1 gigabit per second (Gbps) using just the two of the wire pairs.
