ABSTRACT:
The invention relates to time-division exchanges in which the connection between the subscribers is established successively in time at the same frequency as a sampling of telephone signals. It consists in carrying out the spatial multiplex switching stage simultaneously on k words in series mode, each word using a separate spatial multiplex switch. A spatial multiplex switching stage with k independent elements is thus provided.
