Abstract

PURPOSE:To prevent a PB signal practically sent to a telephone line from being erroneously transmitted without being confirmed. CONSTITUTION:This network controller is provided with a PB signal receiving part 3 for receiving a PB signal outputted from a PB signal sending part 2 and a comparing part 4 for comparing a judged result outputted from the receiving part 3 with a telephone number set up in the sending part 2 by a control part 1 and judging whether their coincidence exists or not. Whether the practically outputted PB signal is correct or not is judged by the comparing part 4 and the judged result is informed a master device to prevent the erroneous transmission.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network control device, and more particularly to a network control device for monitoring an outgoing signal sent to a telephone line.

[0002]

2. Description of the Related Art A conventional network control device of this type has a configuration as shown in FIG. Upon receiving the telephone number signal from the host device, the control unit 1 sequentially sets the telephone number to be transmitted to the PB (push button) signal generation unit 2.
The PB signal generator 2 generates a PB signal corresponding to the telephone number instructed by the controller 1. The PB signal generator 2 is
It is connected to a telephone line and outputs a PB signal to the telephone line.

[0003]

In the above-mentioned conventional network control device, it is impossible to confirm whether the PB signal actually output to the telephone line is the PB signal to be output, and an erroneous PB signal is generated. If it is output, the call will be sent to the wrong person. In particular, when the host device is a computer or the like and is used to automatically notify a bank transfer, there is a problem that information is notified to a wrong partner.

[0004]

The network control device of the present invention comprises:
The control unit that receives the telephone number signal from the host device and issues an instruction to output the push button signal, the push button signal generation unit that generates the push button signal in response to the instruction from this control unit, and the push button signal generation unit The push button signal receiving unit that receives the output push button signal and outputs the reception result, the reception result output by this push button signal receiving unit, and the output instruction output by the control unit are compared and found to match. And a comparison unit that outputs a comparison result indicating whether or not there is.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The controller 1 and the PB signal generator 2 operate in the same manner as the conventional device (see FIG. 2). The PB signal receiving unit 3 receives the PB signal output by the PB signal generating unit 2 and outputs the reception result. The comparison unit 4 compares the reception result from the PB signal reception unit 3 with the instruction of the PB signal output by the control unit 1,
The comparison result indicating whether or not they match is output to the higher-level device.

When a telephone number signal is received from the host device during the calling operation, the control section 1 sequentially sets the telephone number to be generated in the PB signal generating section 2. The PB signal generator 2 is
A PB signal corresponding to the telephone number designated by the control unit 1 is generated. The PB signal generator 2 outputs the PB signal to the telephone line. The operation up to this point is similar to that of the conventional device.

The PB signal receiving section 3 receives the PB signal output from the PB signal generating section 2, determines what the PB signal was, and sends the determination result to the comparing section 4. Comparison unit 4
Compares the determination result sent from the PB signal receiving unit 3 with the telephone number set by the control unit 1 for the PB signal generating unit 2, determines whether or not they match, and A signal indicating the determination result is output to the host device. When the host device receives the signal of the determination result and is notified that the transmitted PB signal is incorrect, the host device sends an instruction to stop the transmission to the control unit 1, or the voice response device If connected, a voice signal such as "Mistaken" is output after the other party responds.

In this embodiment, the PB signal receiving section 3 is
Although it is provided for receiving the PB signal output from the PB signal generator 2, it is also possible to switch and use the one for receiving the PB signal input from the telephone line.

[0010]

As described above, according to the present invention, it is possible to monitor whether or not the PB signal sent to the telephone line corresponds to the telephone number instructed by the host device, thus making an erroneous call. In the case of, it is possible to prevent the wrong party from being notified of the information.
