Abstract

Controlled by the central control processing unit (ZSt), which is responsible for switching operations, not only audible but also independent visual communication is provided in an exchange (VE). This can be carried out in parallel with a call which has been set up or when the terminals concerned are idle. A specific information block, selected from several possible information blocks which are stored in listed form in a memory (T), is displayed selectively at the required terminal without affecting switching system operations. The information which corresponds or is to be allocated to the selected information block is presented, for example, on the display (DL). In the case of special user configurations (e.g. Manager/Secretary systems), the permanent address allocation is predefined in the customer data store (KD) for this visual communication, i.e. wherein the actual speech path (switching device, PCM highway) is not occupied. The individual texts which are to be presented on the display (DL) via the control channel (c/d) may be selected from all the stored texts by means of, for example, a key permanently assigned to each text or through a corresponding procedure. <IMAGE>
