Abstract

A Power Line Communications (PLC) device includes a processing module, memory, and a communication interface. In a first operation, the PLC device determines that the PLC device will service communications with a first remote PLC device according to a first PLC communication standard and configures the communication interface to service communications according to the first PLC communication standard. In a second operation, the PLC device determines that the PLC device will service communications with a second remote PLC device according to a second PLC communication standard and configures the communication interface to service communications according to the second PLC communication standard, wherein the first PLC communication standard and the second PLC communication standard are differing and incompatible PLC communication standards. The PLC device may also configure the communication interface to service non-PLC communications such as LAN, WAN, WLAN, cable modem, and other communications.
