ABSTRACT:
The invention relates to switching matrices used in exchanges of time-division kind and to networks using that kind of matrices. It consists in utilizing at the input and output of a symmetrical time matrix, a multiplexer and a demultiplexer which enable the overall circuit to address an arbitrary IT (time slot) of an arbitrary incoming junction, to an arbitrary IT on an arbitrary outgoing junction. A network using only that kind of matrices is disclosed.
