ABSTRACT:
A communication system, method and program product are provided for establishing an extended bidirectional communication bus between a first device and a second device. The communication system includes decomposition logic for decomposing a single line, bidirectional data communication bus into a unidirectional transmit data communication bus and a unidirectional receive data communication bus. A differential communication subsystem is connected to the two unidirectional buses for extending the length thereof, and recomposition circuitry is connected to the differential communication subsystem for recombining the extended unidirectional transmit data communication bus and the extended unidirectional receive data communication bus to reestablish the single line, bidirectional data communication bus. The decomposition logic, differential communication subsystem and recomposition circuitry are implemented transparent to the first device and the second device and without use of a data direction control line.
