Abstract
A router that utilizes one additional crosspoint module to provide backup to N crosspoint modules. The redundant crosspoint module receives every input from P input modules and provides O/N outputs to M output modules. Each of the M output modules receives an output from a particular N crosspoint module and a corresponding O/M output from the redundant crosspoint module. Each output module has logic to determine whether the output module should select the output from a particular N crosspoint module or the output of the redundant crosspoint module.
