Abstract
A method of signaling between Ethernet transceiver link partners along a link is disclosed. The link includes between one to four twisted pair channels. The method includes, in an offline mode of operation, autonegotiating between the link partners during an autonegotiation sequence. A number of active pairs out of the one to four pairs of twisted pair channels is then discovered. The discovering includes transmitting a discovery signal from a transmit end of the link on the active pairs, detecting the transmitted discovery signal at a receive end of the link, and identifying the active pairs based on the detecting. The link active pairs are then trained to train transceiver operating parameters with a training sequence of symbols. In an online mode of operation, the link is operated in a data transfer mode utilizing at least one of the identified active pairs.
