Abstract
A communication bus user design that significantly reduces the likelihood of bus disablement. Request to transmit received by a user are validated in the communications processor and by an interlock circuit. Logic signals generated in response to the two validations are coupled to an AND gate, wherefrom an enabling signal is coupled to an amplifier when the two logic signals coincide. Communications signals from the communications processor are thereafter coupled via the amplifier to the bus.
