Abstract
A multi-port Ethernet Physical (PHY) layer device includes multiplexed datapaths and control logic such that each transmit data connection for a port may be mapped to any combination of the transmit data connections for one of multiple Media Access Control (MAC) layers, and each received data connection for a port may independently be mapped to an combination of the receive data connections for one of the MAC layers and the transmit data connection(s) for the other port(s). The device may be configured to operate in normal and port swap modes, to support failover switching and/or dedicated redundant connections, as a cable extender or media converter, as a snoop device, to form an Ethernet ring topology, for broadcast transmit or mirrored receive, or as a unidirectional repeater.
