Abstract
A transceiver device for coupling between a power line and a network interface unit includes a power line modem for transmitting and receiving data between the power line and the network interface unit and a power circuit coupled to the power line modem that is adapted to deliver a DC power signal to the network interface unit. The power circuit includes a discovery circuit adapted to determine the type of network interface unit that is attached. A load path control circuit switches the DC power signal between a PHY interface and a connector interface of the power line modem based on the determined type.
