Appl. No.:
09/561194
Inventors:
Michael R. McDonald - Sunnyvale CA

Abstract:
An interface circuit for allowing a computer system to communicate over existing household wiring in multiple frequency bands. The interface circuit includes an isolation circuit that connects the interface circuit to the household wiring. An analog-to-digital/digital-to-analog converter receives analog signals in multiple frequency bands and digitizes them. A digital splitter/combiner operates to filter the combined frequency digital signals received from the analog-to-digital/digital-to-analog converter. The frequency bands preferably comprise a voice band typically used for transmitting voice telephone signals, a DSL band for transmitting and receiving high-speed digital data over a twisted pair of telephone wires, and a Home PNA frequency band used for networking computers and peripherals on a twisted pair of telephone wires. The digital splitter/combiner feeds circuits designed to transmit and receive data in each of these frequency bands so that the computer system can transmit and receive data on whatever band is available.
