1. A digital signal switching system comprisinga multi-stage space-division switched network having N input terminals and M output terminals, said switched network providing a plurality of internal digital signal transmission paths where each stage includes a certain number of switches for normally switching said digital signals between each input and one or more outputs in each stage, each of said internal signal paths connecting one of said input terminals to any one or more of said output terminals through each stage only through said certain number of switches, andmeans for simultaneously rearranging in a non-blocking fashion any number of said internal signal paths for each stage of said network where said digital signals are switched only through said certain number of switches without changing their end points and without disturbing the digital signals received at the output terminals of said rearranged paths.
