ABSTRACT:
A switching configuration for PCM TDM telecommunication exchange insallations, having a central switching network and individual sub-switching networks is provided.
Line groups having duplicated central switching networks connected over two time division multiplex lines and having a sub-switching network and a group control system each are assigned to each other in pairs. The line systems assigned individually to the one and the other of two line groups and which are connected via internal lines in normal operation to the sub-switching networks of their own line group, can be switched over to the sub-switching network of the other line group. No connections are interrupted which were already through-connected before changeover switching or were in the process of being set up, and the internal lines running form the line system of one line group can be switched over singly, i.e. individually to the connection, from its sub-switching network to that of the partner line group. Unseized internal lines are switched over, or also connections in the call phase are through-connected. For new connections, only already switched-over internal lines are available.
