ABSTRACT:
A circuit arrangement is described for the reception and transmission of switching data associated with communication signals being transmitted to or from an exchange in a telecommunication system. In the system the signals are transmitted between exchanges by pulse code modulation techniques. Each exchange is provided with separate receiving/transmitting devices for the communication signals and the switching data signals, and each communication receiver/transmitter has a switching data receiver/transmitter assigned thereto. The latter are connected to a common control unit.
