Abstract

A crosspoint switch having M input terminals and N output terminals has (M/m) times (N/n) crosspoint switch modules each having m input conductors and n output conductors. (M/m) of the crosspoint switch modules have their input conductors connected to the M input terminals respectively of the crosspoint switch, and (N/n) of the modules have their output conductors connected to the N output terminals respectively of the crosspoint switch. The input conductors of the first module are connected to respective input conductors of a second module and the output conductors of the first module are connected to respective output conductors of a third module.
