Abstract
The disclosure describes communication of information between a network interface device and subscriber devices over a power line. A UPS unit receives operating power from subscriber premises via a first power line and delivers operating power to the network interface device via a second power line. The network interface device transmits and receives information, such as voice, video and data, to and from the UPS unit via the second power line. The UPS unit receives the information transmitted by the network interface device via the second power line, and transmits the received information to subscriber devices within the premises via the first power line. The UPS unit receives information transmitted by subscriber devices via the first power line, and transmits the received information to the network interface device via the second power line. The first and second power lines each serve as both a power line and a communication medium.
