This data transmission device serves to connect a plurality of subscribers (T1 ... Tp) to a central exchange, the number of channels of the transmission device being lower than the number of subscribers. The transmission is carried out via a frequency division multiplexing device (16, 17, 18; 26, 27, 28) and, with the aid of a central control device (14), a switching device (13) connected to the exchange-side terminal is controlled directly and at least one allocation device (23) for connection set-up which is connected to a subscriber-side terminal is controlled by means of a telecontrol device (15, 25). <IMAGE> |
