ABSTRACT:
A system and method are disclosed that provide for compatibility between different generations of transceivers, such as Gigabit Ethernet transceivers. According to the invention, a novel transceiver is provided that includes a physical layer entity (PHY) comprising a physical coding sublayer (PCS) and a physical medium attachment (PMA) sublayer. In one embodiment, the PHY is designed to switch the PCS encoding/decoding scheme to a legacy-based encoding/decoding scheme in a situation where it is determined that the remote transceiver in communication with the novel transceiver is transmitting data according to a legacy-based scheme.
