Abstract

Each terminal is activated only when the balance in a user account has been read and the account has been made available for debiting. The terminal includes a monitor system for playing out and receiving voice and picture information, an interface system for conditioning signals passing between the monitor system and the telephone network, and a database which contains the locations and telephone numbers of other terminals of the videoconferencing network. The terminal firer includes a display of information from the database, a pointing device by means of which a user can make a selection from the display by indicating the relevant position in the display, and a device for automatically dialing up the selected remote terminal.
