ABSTRACT:
With the switching node at least one coupling element is associated which has a number n of input lines and n output lines optionally connectible to the input lines via a space switch with a buffer store being assigned to the input lines in which k data packets occurring sequentially on the particular input line are storable before being routed further to the output lines indicated by the address signals contained in the particular data packet. The buffer stores have each a plurality m.ltoreq.k output terminals via which simultaneously m data packets stored in the particular buffer store and to be routed further to m different output lines are suppliable to a space switch having m.times.n input terminals and n output terminals.
