Abstract
Aspects of a method and system for extended range Ethernet link discovery signaling are provided. A local PHY may detect of one or more active twisted-pair wires in a remote PHY in extended range applications. The local PHY may determine whether to operate as a master or slave based on detected pairs. When operating as a master device, the local PHY may correct twisted-pair wire swap information received from the remote PHY before communicating an encoded link length value to the remote PHY. When operating as a slave device, the local PHY may transmit encoded twisted-pair wire swap information to the remote PHY before recovering a link length value communicated from the remote PHY. The local PHY may communicate supported operating modes based on the link length value to the remote PHY. Moreover, the local PHY may enable establishing a common full duplex operating mode with the remote PHY.
