Abstract

PURPOSE:To automatically identify a caller at an incoming side, by enabling to transfer a self-identification code through the direct access to an incoming device from a rotary dial type telephone set, by connecting code information stored in advance in a memory to a telephone subscriber line via a DTMF dial. CONSTITUTION:Output information of a key pad 1 is applied to a controller 4 via a decoder 2 and stored in a memory 3 in advance. An output from the controller 4 is converted into pulses interrupting DC current with a pulse dial 5, and an output of the controller 4 is converted into a combination signal of two frequencies with a DTMF dial 6. A line interface 7 connected to a rotary dial type telephone set 8 is connected to the output of the dials 5 and 6, calling is made by hooking up a handset of the telephone set 8, and the output of the pad 1 is connected to a telephone subscriber line 9 via the dials 5 and 6 for the access to the incoming device. The telephone set 8 makes access to the incoming device directly and the self-identification code is transferred.
