1. A non-blocking wide bandwidth system for connecting a plurality of incoming signal lines (100) to a plurality of outgoing signal lines (110), each of said incoming lines carrying time multiplexed signals and each of said signals having a characteristic bandwidth and a destination address accompanying its data, said system comprising:

  • a demultiplexer (101) connected to each of said incoming lines and demultiplexing said time multiplexed signals to form an alterable plurality of signal channels, each having the same preselected bandwidth;

    a non-blocking space division switch (10) having switch input and output ports and responsive to said signal channels of said demultiplexers applied to said switch input ports, for simultaneously switching the signal of each of said signal channels to a switch output port which is related to said destination address accompanying the data of said signal; and

    a plurality of multiplexers (104), each multiplexing the signals of a chosen number of said switch output ports onto one of said outgoing signal lines.
