ABSTRACT:
A switch network comprises N input ports and T output ports for mutually and individually connecting any P (P.ltoreq.N and P.ltoreq.T) inputs and any P outputs. Each switch has four poles and is capable of connecting the first pole to a second, a third or a fourth and correspondingly connecting the third pole to the fourth, first or second poles. The network includes switches disposed in a matrix network including internal switches each connected by its four poles to four adjacent switches and peripheral switches each located on the periphery of the matrix network. At least some of the peripheral switches are connected by at least one pole to an input or an output and by at least two other poles to two switches of the network.
