Abstract

The invention relates to a switching network for a switching system in which cells are transmitted in accordance with a time division multiplex method and the through-connection is effected by means of the routing information contained in the header of the cells. The blocks arriving at the switching node are temporarily stored in a queuing buffer until a free frame is available. A switching network should be configured in such a manner that the number of buffer spaces can become as small as possible and buffer spaces only need to be provided for data which are to be forwarded via the associated serving trunk. To this end, it is proposed to allocate a comparator to each offering trunk, the comparator comparing the address of the serving trunk with the routing information and the cells supplied in the offering trunk only being entered into the buffer store associated with the serving trunk in the case of a correspondence between routing information and stored address of this serving trunk.
