ABSTRACT:
The invention relates to the connection networks used for switching digital signals, more especially telephonic PCM signals. It consists in organizing the spatial stage of a network of the TST type operating in series mode so as to divide into two the number of switching planes of that network. Each plane is with blocking although the assembly is without blocking. Moreover the number of time paths that enables the spatial stage to be traversed is doubled.
