Abstract

The method according to the invention for the calculation of the cross-connection configuration in a time-space-time (T-S-T) is based on the fact that the examined data streams are divided into defined periods. Within a period the connection matrix (31) is generated by the calculator (32) for each time slot, so that first a suitable space switch output is found, and then a signal of such an input time switch is selected, which can be connected to the selected output. According to the invention the capacity of the cross connect can be effectively utilized without arranging e.g. extra capacity for the space switch. <IMAGE>
