Abstract
An expanded WIRE-OR Bus structure has a first WIRE-OR Bus arrangement and a second WIRE-OR Bus arrangement. Each of the first and second WIRE-OR Bus arrangements have connected thereto at least one driver element and at least one receiver element. An intelligent bi-directional signal coupling circuit includes a buffer element, a bus arbiter, and a bus driver amplifier. The coupling circuit couples signals between the first WIRE-OR bus and the WIRE-OR second bus, and prevents signals originating on one of the WIRE-OR buses from being coupled back to the same WIRE-OR bus.
