PURPOSE: To provide a new service such as a relay or an electronic bulletin board service by using a personal computer and a facsimile modem. CONSTITUTION: When a network control circuit 11 detects the arrival of a call through a communication line 3, the control circuit 11 informs the arrival of a call to a PC 2, the PC 2 sends a reply command to a command processing section 15 and the command processing section 15 gives a reply command to a communication control section 14 and the communication control section 14 sends an initial identification signal to the communication line 3. A PB signal detection circuit 12 detects a PB signal from a signal of a caller facsimile equipment and informs the reception of the PB signal to the command processing section 15 through the communication control section 14, the command processing section 15 informs it to the PC 2 by an AT command and receives a command from the PC 2 succeedingly to conduct processing designated by the PB signal. When the network control circuit 11 receives a facsimile procedure signal, the communication control section 14 informs the facsimile procedure signal to the PC 2 through the command processing section 15.

However, the above-mentioned conventional G3 facsimile modem device has only the function of the facsimile procedure, and cannot detect the PB signal from the incoming signal from the communication line. Further, the facsimile terminal device described in the above publication does not control communication using the received touch-tone signal.

Therefore, these conventional apparatuses have a problem in that new services such as relay and electronic bulletin board using the PB signal provided by the high-level facsimile system cannot be provided to the user.

An object of the present invention is to use a personal computer and a facsimile modem device by detecting the PB signal from the calling side facsimile device and notifying the personal computer side using the result of the AT command or the like. Another purpose is to provide a facsimile modem device capable of providing a relay service or an electronic bulletin board service to a user.

According to the present invention, a detecting means for detecting an incoming call from a communication line and transmitting an initial identification signal and then detecting a facsimile procedure signal and a push button signal from a calling side facsimile device. And a command processing means for discriminating the facsimile procedure signal and the push button signal detected by the detecting means and transmitting a command of a predetermined format to the personal computer side. Is obtained.

A network control circuit for detecting an incoming call from the communication line, a push button signal detection circuit for detecting the push button signal from an incoming signal received by the network control circuit, and the network control circuit for receiving an incoming call. A communication control unit that sends the initial identification signal when detected, a modulation / demodulation circuit that modulates / demodulates a facsimile procedure signal transmitted / received between the network control circuit and the communication control unit, and the facsimile detected by the network control circuit. A facsimile modem device is provided, which comprises a command processing unit for discriminating between a procedure signal and the push button signal and transmitting the command of the predetermined format to the personal computer side.

Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a facsimile modem device of the present invention.

Referring to FIG. 1, G3 in this embodiment
The facsimile modem 1 is connected to a general exchange (not shown) through a communication line 3, detects an incoming signal from the communication line 3 and sends an initial identification signal, and then a facsimile machine from a calling side (not shown). The facsimile procedure signal and the PB signal are detected, the detected facsimile procedure signal and the PB signal are discriminated, and a command of a predetermined format is sent to the personal computer (PC) 2.

The G3 facsimile modem 1
Is a network control circuit 11 for detecting an incoming call from the communication line 3.
A PB signal detection circuit 12 for detecting a PB signal from an incoming signal received by the network control circuit 11, and a communication control unit 1 for sending an initial identification signal when the network control circuit 11 detects an incoming call.
4, and a modulation / demodulation circuit 13 that modulates / demodulates a facsimile procedure signal transmitted / received between the network control circuit 11 and the communication control unit 14.
And a command processing unit 15 that discriminates the facsimile procedure signal and the PB signal detected by the network control circuit 11 and sends a command to the PC 2 side.

Next, the operation of this embodiment will be described.

When the network control circuit 11 detects an incoming call from the communication line 3, the network control circuit 11 notifies the PC 2 of the incoming call through the communication control section 14 and the command processing section 15.

Upon receiving this incoming notification, the PC 2 sends a response command to the command processing section 15, and the command processing section 15 issues a response instruction to the communication control section 14.

Upon receiving this response instruction, the communication control unit 14 sends an initial identification signal to the communication line 3 through the modulation / demodulation circuit 13 and the network control circuit 11.

Thereafter, the signal from the calling side facsimile machine is input to the modulation / demodulation circuit 13 and the PB signal detection circuit 12 through the network control circuit 11.

When the signal from the calling side facsimile apparatus includes the PB signal, the PB signal detection circuit 12
Detects this and notifies the communication control unit 14.

When the communication control unit 14 notifies the command processing unit 15 of the PB signal reception, the command processing unit 15
Notifies the PC 2 in a predetermined format (for example, AT command).

After that, the G3 facsimile modem apparatus 1 performs the processing designated by the PB signal, such as the transmission processing of a specific document, according to the instruction from the PC 2.

When the network control circuit 11 receives a facsimile procedure signal from the communication line 3, the network control circuit 11
The demodulation circuit 13 demodulates the facsimile procedure signal and transmits it to the communication control unit 14.

The communication control unit 14 notifies the PC 2 of this demodulated facsimile procedure signal through the command processing unit 15.

After that, the G3 facsimile modem apparatus 1 performs a normal facsimile reception process in accordance with the instruction from the PC 2.
