Abstract

PURPOSE:To accurately perform communication management even for mixed communication by comprising a device so that the analytic result of a facsimile signal can be taken out from a terminal adaptor main control part. CONSTITUTION:When a response request is issued from an INS net to a terminal adaptor device main body, the terminal adaptor device main control part 1 sends a call signal to existing terminal equipment 5 connected to the terminal adaptor device main body. When off-hook is performed by the existing terminal equipment 5, communication can be established by detecting the above off-hook by the terminal adaptor device main control part 1, and also, the monitoring of an analog signal line 2 is started by a modem 3. Then, the facsimile signal of analog signal from the terminal adaptor main control part 1 is monitored by the modem 3, and is analyzed and judged at a facsimile signal analysis part 4. In such a way, the communication management can accurately be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a terminal adapter device that allows existing terminal devices to be connected to an INS network.

Existing terminal devices such as conventional technology IEif and facsimile can be used as INS.
When a terminal adapter device that enables connection to the Internet receives a call using a telephone or a G2/G3 facsimile, the INS user network interface determines whether the other party's terminal is a telephone or a facsimile, and the communication begins. It is generally known to determine and express whether a call is a telephone call or a facsimile call in a management report or the like.

Problems to be Solved by the Invention However, with such a conventional terminal adapter device, it is difficult to perform facsimile communication with the line connected after making a telephone call, such as with a G3 facsimile with a telephone. In addition, when the attributes of a terminal are changed during communication, it is impossible to determine that the type of terminal has changed during the communication on the INS user network interface, so mixed telephone and facsimile communication may occur during one call. There was a problem in that it was impossible to express what happened in a communication management report or the like.

The present invention solves the above-mentioned problems, and aims to provide a terminal adapter device that enables accurate communication management even in mixed communication.

Means for Solving the Problems In order to achieve the above object, the present invention provides a terminal adapter main control section connectable to the INS net, and an analog signal line connecting the terminal adapter main control section and existing terminal equipment. and a modem that monitors the signal of this analog signal line, and a facsimile signal analysis section that analyzes the signal detected by this modem, and is configured such that the analysis result of the facsimile signal can be retrieved from the terminal adapter main control section. ing.

According to the above-described configuration, the present invention analyzes and determines whether or not a facsimile communication has been made during one communication by monitoring the facsimile signal using the modem and the analog signal sent from the terminal adapter main control unit to the existing terminal device. ,
The communication attributes can be determined from the terminal adapter main control unit.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG.

In the figure, reference numeral 1 denotes a terminal adapter device main control unit connected to the INS net, and this terminal adapter device main control unit 1 is connected to an existing terminal device 5 such as a G3 facsimile machine with a telephone using an analog signal ll52. It is connected. The analog signal 12 is equipped with a modem 3 that monitors the signal being transmitted, and a facsimile signal analysis unit that analyzes the signal detected by the modem 3 and determines whether or not it is facsimile communication. It is structured as follows.

The operation of the above configuration will be explained below.

When there is a response request from the INS net side to the terminal/adapter main unit, the terminal/adapter main control unit 1
sends a call signal to the existing terminal device 5 connected to the main body of the terminal adapter device.

When the existing terminal device 5 goes off-hook, the terminal/adapter device main controller 1 detects this and establishes communication, and the modem 3 sends an analog signal &l! 2
Start monitoring.

When the modem 3 detects a facsimile signal, it means that the connected existing terminal device 5 has started facsimile communication, and by analyzing the procedure in the facsimile signal analysis unit 4, it is possible to determine whether there is facsimile communication, the communication time, and the communication. The results etc. are notified to the terminal/adapter device main control section 1.

If the modem 3 does not detect a facsimile signal, this indicates that the connected existing terminal device 5 is in a telephone communication state.

When the existing terminal device 5 goes on-hook or the line is disconnected, the terminal/adapter device main control unit 1 detects this and recognizes the end of 1 communication, and also allows the modem 3 to monitor the analog signal line 2. finish.

From the above, the terminal/adapter device main control unit 1 can confirm that the contents of one communication are in three communication states: telephone communication, facsimile communication, and mixed telephone and facsimile communication.
This result can be used as information such as a communication management report.

Effects of the Invention As is clear from the above description of the embodiments, the facsimile signal is monitored by the modem using the analog signal from the main control section of the terminal adapter, and the facsimile signal analysis section analyzes the facsimile signal to make a decision. Even in the case of mixed facsimile communication, it is possible to express the fact that it was mixed communication in a communication management report, etc., and more accurate communication management becomes possible, which has a great practical effect.
