Abstract

PURPOSE: To reduce a re-dialing time and to facilitate an operation, by providing a means which sets a base unit as an automatic answering telephone when no wave of a handset arrives at the base unit, a reception circuit, a memory device, a call tone generation circuit, a D/A circuit, and a control circuit to control those circuits.
CONSTITUTION: When communication between the handset and the base unit is disabled, no signal is inputted to a reception detection circuit 108. The reception detection circuit 108 outputs a carrier interruption signal NCR to the control circuit 116, an automatic incoming circuit 111, and a timer circuit 112. The automatic incoming circuit 111 switches both contacts of change-over switches 119 and 120 to contact B sides by the timer circuit 112 when the above time exceeds a certain value. The automatic incoming circuit 111 inputs an on-hook signal to the control circuit 116, and makes a hook switch 118 contact with a contact B on an on-hook side. The control circuit 116 takes out voice information from the memory device 102 via the D/A circuit 103, and outputs the voice information to a hybrid circuit 117 via a low frequency amplifier 115.
