Abstract

PURPOSE: To eliminate complicated manual operation and response operation on a caller side and a caller side, by providing a control means which selects a device receiving incoming call from plural terminal equipments corresponding to a dial signal transmitted from the caller side after connecting a line.
CONSTITUTION: An incoming terminal is designated by transmitting a dial tone by dialing (#1∼#4) and a (*) behind a telephone number from the caller side. When a call signal is detected by a call signal detection circuit 3, a DTMF detection circuit 5 is connected to the line. Thereby, the DTMF detection circuit 5 forms a DC loop, and the line is connected. And when the DTMF detection circuit 5 detects the receiption of the tone (#), a numerical tone is detected, and the bell of a telephone set corresponding to a detected number tone is rung, then, the operator of the telephone set is called. Thus, since the incoming device can be designated by transmitting the dial tone from the caller side, a targeted operator can be called immediately in the case of communication, and also, it is possible to make the complicated manual operation of the operator on the incoming side unnecessary in the case of facsimile communication.
