ABSTRACT:
A plurality of cross-point matrices each having a plurality of holding circuits respectively associated with a corresponding cross point are arranged in multiple stages, which are linked with each other to form a multi-stage switching network. Each switch matrix is provided with an associated NAND gate connected to gates capable of being selectively impressed with the signals representing the state of the holding circuits in a row or column within the particular switch matrix. The output of the NAND gate is connected to an OR gate for each stage.
