Abstract:
A network device includes a media access controller (MAC) and a physical layer having an interface that communicates with the MAC. A first autonegotiation circuit attempts to establish a link using a first transceiver over a first media. A second autonegotiation circuit attempts to establish a link using a second transceiver over a second media. A media selector communicates with the interface and the first and second autonegotiation circuits. The media selector enables data flow from the first media to the MAC using the interface when a link is established first over the first media. The media selector enables data flow from the second media to the MAC using the interface when a link is established first over the second media.
