ABSTRACT:
The present invention is directed to a circuit arrangement for connecting a voice-controlled additional facility associated with a telephone station to a telephone line. According to the invention a telephone station (32) is connected with a voice-controlled additional facility (2). The additional facility (2) performs voice-controlled telephone dialing and/or voice-controlled operation of a videotex terminal. This is implemented by a connection unit (14) inserted in the telephone line (16). The connection unit (14) cooperates with the exchange to permit calls to be initiated, in the known manner, by means of a keypad at the telephone station (32). Any type of telephone station (32) can be connected to the voice-controlled additional facility (2) without any engineering modifications.
