Abstract
A system is added to a terminal device for automatically responding to a ringing signal of a telephone set and receiving information. Upon reception of an incoming call, an automatic telephone answering apparatus is started to send an outgoing message to a calling party. Thereafter, in response to a remote control signal supplied from the calling party, a ringing signal generating circuit is operated to generate the same signal as the ringing signal of the telephone set. The system to be connected to the telephone circuit independently can be operated without being modified, and the terminal device is started in response to the ringing signal generating circuit, so that the terminal device is connected to the telephone circuit to receive information.
