ABSTRACT:
Switching circuitry for automatically connecting two sets of terminals in two circuit modules, through a larger set of conductors, some of which may be defective or unavailable for other reasons. The circuitry includes two identical switching matrices, each of which receives signals indicative of the availability status of the conductors, and connects the terminals to an available subset of the conductors. Each switching matrix has an array of switching cells arranged in such a manner that a cell will connect a terminal to a conductor unless the conductor is not available, or unless the same terminal has already been assigned to another conductor, or the same conductor has already been assigned to another terminal.
