Abstract

PURPOSE:To obtain an economical communication adapter of a facsimile device by constituting this adapter so that various kinds of service can be added without remodeling neither adding the facsimile device. CONSTITUTION:When a network control part 2 of a communication adaptor 10 detects an incoming signal by incoming from a line 1 and reports this detection to a control part 7, the control part 7 connects the network control part 2 to a service processing part 4 through a switching part 3 and instructs the network control part 2 to close a DC loop. The service processing part 4 executes a prescribed service (for example, the automatic response announce function) in accordance with a service request signal from the line 1. When the execution of the service is terminated, the control part 7 starts a trunk part 5 to transmit a call signal to a facsimile device 6. When the trunk part 5 detects it by closing of the loop that the facsimile device 6 is started by the call signal, the control part 7 operates the switching part 3 to connect the network control part 2 to the trunk part. By this connection, facsimile communication procedures between the facsimile device 6 and the line 1 are possible.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a communication adapter for a facsimile machine.

In particular, the present invention relates to a communication adapter that can switch services.

[Conventional technology]

An example of a communication adapter that is added to a facsimile machine and provides certain service functions is an automatic response announcement unit (abbreviated as ARU).

The automatic response announcement function automatically sends a predetermined message (for example, "This is...
is. This is a function that sends out and responds to a "signal."

[Problem that the invention seeks to solve]

Conventionally, communication adapters are added to facsimile machines to provide various service functions as described above.

Generally, it is necessary to add some extra interface functions to the facsimile machine, and it is technically and economically difficult to add these interfaces when selling the facsimile machine.

An object of the present invention is to provide a facsimile communication adapter that can be connected to a facsimile machine to which a communication adapter is attached without any addition or modification.

[Structure of the invention]

According to the present invention, a network control unit capable of detecting incoming calls from two lines and a facsimile machine are connected to make a call.

a trunk section that can monitor responses; a service processing section 5 that executes a predetermined service; a switching section that switches and connects the output of the network control section to one of the trunk section and the service processing section; and the network control section. .

There is obtained a facsimile communication adapter characterized in that it includes a control section that controls each section of the switching section, the service processing section, and the trunk section.

〔Example〕

Next, two embodiments of the present invention will be described with reference to one drawing.

Referring to FIG. 1, a facsimile communication adapter 10 according to an embodiment of the present invention is connected to a telephone line 1 and has a network control section 2 having an incoming call detection function.

A switching unit 3 connected to the network control unit 2, a service processing unit 4 connected to the network control unit 2 via the switching unit 3, and a service processing unit 4 connected to the network control unit 2 via the switching unit 3. a trunk section 5 whose input is connected to the facsimile machine 6 and whose output is connected to the facsimile machine 6;

and a control section 7 that controls each section of 4 and 5.

Still, FIG. 2 shows an example of the operation procedure in the embodiment of FIG. 1. In FIG. 2, (A) shows an example of a case where a service is provided within the communication adapter lo of the embodiment, and (B)
) shows an example where the process cannot be completed only with the communication adapter in use.

The operation of the embodiment will be described with reference to FIGS. 1 and 2.

First, referring to FIG. 2(A), two
Network control unit 2 of ib communication adapter 1° receives a call from line 1.
'÷When the bengyu komabetsurochi detects an incoming signal and notifies the control unit 7, the control unit 7 connects the network control unit 2 to the service processing unit 4 via the switching unit 3, and the network control unit 2 to close the DC loop.

The service processing unit 4 executes a predetermined service (for example, the above-mentioned automatic response announcement function) in response to a service request signal from the line 1, for example. When the execution of the service is completed, the control unit 7 activates the trunk unit 5 and sends a calling signal to the facsimile machine 6. When the rank section 5 detects that the facsimile device 6 has been activated by a paging signal (by closing the loop), the control section 7 operates the switching section 3 to connect the network control section 2 to the trunk section. This connection allows facsimile communication procedures to be performed between the facsimile device 6 and the line 1.

In the example shown in FIG. 2(B), if a service request signal is not received even after a predetermined period of time has elapsed after responding to the call signal from line 2, it is assumed that the communication is a general facsimile communication and the facsimile device 6 is It is activated by a ringing signal (16 Hz) and performs general facsimile communication between the second line 1 and the facsimile machine 6.

〔Effect of the invention〕

As described above, the present invention has the effect of providing an economical communication adapter for a facsimile machine by being configured so that various services can be added to the facsimile machine without modification or addition.
