Abstract
A novel method of operating a physical layer device in a local area network, such as one conforming to Ethernet protocol, to make a single physical layer device compatible with Physical Media Dependent (PMD) devices operating over different network media types. The methodology involves monitoring signal detect inputs and based on their levels, automatically reconfiguring the physical layer device to support interface to a required PMD device. In a preferred embodiment, a physical layer device in a network transceiver for interconnecting a hub device and PMD devices has first transmitting and receiving paths for supporting interface to a first PMD device, such as 100 BASE-TX, and second transmitting and receiving paths for supporting interface to a second PMD device, such as 100 BASE-FX.
