DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device such as a facsimile apparatus with a cordless handset having an answering machine function for recording and reproducing a message from an outside line, and more particularly to a cordless handset and an answering machine from an outside line. The present invention relates to a communication terminal device capable of remotely operating a telephone function.

2. Description of the Related Art In a conventional facsimile apparatus with a cordless handset having an answering machine function, a remote operation such as listening to or deleting a message recorded by the answering machine function from an external telephone or a cordless handset is performed. It is possible. When operating remotely from an outside line, the user calls the facsimile machine with a push-button dial-type telephone, and when the line is connected, inputs a pre-registered password with the push button, and the password is accepted by the facsimile machine. Then, a code number assigned for each type of remote operation such as sending or erasing of recorded contents is input by a push button.

A DTMF (Dial-Tone Multi Frequency) comprising a combination of frequencies according to an operated push button dial
ency) signal is sent from the external telephone to the facsimile machine, and in the facsimile machine that receives this signal, the DTMF decoder of the facsimile control unit that controls the communication analyzes the DTMF signal, determines the dialed digit, and based on the determination result. It sends a message to an external telephone and deletes a recorded message.

When a remote operation is performed from a cordless handset, the base unit receives a command signal for remote operation from the handset and outputs the command signal to, for example, a facsimile control unit via a serial interface. This signal is different from the DTMF signal in remote operation. Therefore, the facsimile control unit analyzes the command signal from the slave unit with a circuit different from the DTMF decoder, and sends and deletes the recorded message.
