摘要：A multi-stage, alternate routing switching network is enhanced with a switcharchitecture that is able to detect and mask all single faults. The switch employs acontroller that develops dual rail control signals. In one embodiment, the controller ismade up of two controllers that receive the same inputs but generate complementaryoutputs. The complementary outputs form the dual rail signals that control themultiplexers that are interposed between the inputs and the outputs of the switch. Thedual rail control of the signal routing within the switch allow for effective detection of allsignal faults in the signal routing means. Inclusion of totally self checking circuits at theswitch outputs as well as inputs enables users to readily isolate a fault and identify itssource.
