ABSTRACT The invention relates to a switching network for a communication system, which is structured like a space-division multiplex switching network comprising m/l stages which include auxiliary lines and have each a trunk line and in which cells are transmitted in accordance with a time-division multiple access method and the cells are switched through on the basis of the routing information contained in the cell header and in which the cell arriving at the auxiliary line is written into the buffer dedicated to the trunk line if the routing information and address of this trunk line match and in which a decision circuit is included. The switching network is specifically suitable for use with asynchronous time-division multiple access methods. Each stage of each auxiliary line is assigned a memory to which are applied the results of the comparisons of the routing information and address of the trunk line. The contents of the memory are applied to the decision circuits which, on the basis of these contents, determine the order in which the cells stored in the buffers are read out.
