Abstract
In the framework of the development of future, integrated wideband networks, specifically the arrangement of the switching networks and switching network controls is of particular importance. In a switching network arranged in accordance with a space-division multiplex switching network each switching point comprises a comparator, comparing the addresses of the trunk lines arranged column-by-column to the routing information. When there is multiple correspondence in a column a decision circuit assigned to the trunk line decides the order in which the switching points are to switch. In addition, an input buffer is connected to each supply line, in which buffer the blocks are temporatily stored until they can reach one of the trunk lines. To avoid the occurrence of bottle-necks in the performance of the switching network an input buffer is assigned to each switching point or the switching network is arranged column-by-column and built up of units of equal structure.
