JPS6331257A - Automatic communication identifying controller for call signal at incoming side - Google Patents

Abstract

PURPOSE:To improve an operation efficiency and to save labor by detecting a remote signal at the time of an automatic incoming, identifying the communication device and the communication system of a remote side and switching the communication device and the communication system of its own side to the remote side. CONSTITUTION:When there is an incoming, a network control part 1 detects a bell signal and responds to a telephone, it outputs an incoming detection signal to a line control part 8. Switches 5a, 5b are turned on and a V27 ter modem 5 is connected. When the line control part 8 receives the incoming detection signal, it monitors a signal from a 1100 Hz detection circuit 2, a 980 Hz detection circuit 3 and the modem 5. When the remote side is GIII facsimile communication, for instance, the detection circuit 2 is turned on, and the control part 8 informs the incoming from the GIII facsimile to a main control part 9. The main control part 9 receives it and switches a communicating control program to the program for the GIII facsimile.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device used in communication using a telephone line network, and in particular to a device that automatically switches between a plurality of different communication devices and communication methods to perform communication. The present invention relates to a communication control device that enables communication control.

[Conventional technology]

A device that can handle multiple communication methods among communication devices that automatically receive a call using a telephone ring when communicating using a telephone line network. A facsimile device is an example of a communication device having a function of automatically identifying a called party by switching the side communication method.

For example, in a facsimile machine, when a call is received, a predetermined signal is issued from the calling side, and by identifying this signal, the receiving side automatically switches between communication methods such as G■ Sofasimile and GIII facsimile.

[Problem that the invention seeks to solve]

Automatic switching of the communication method in such a facsimile device is performed only during facsimile communication. Therefore, if a telephone line is used for both facsimile communication and data communication using a computer, it is not possible to automatically receive calls because a person has to switch between communication devices, which is extremely inconvenient. Met.

An object of the present invention is to eliminate such inconveniences and to provide a communication control device for automatic identification of called parties, which enables automatic switching of communication devices and communication methods when a telephone line is used for multiple types of communication. It is about providing.

[Means for solving problems]

The present invention is a called party automatic identification communication control device that performs communication by automatically receiving a call using a telephone line network, and when automatically receiving a call, it identifies the communication device and communication method of the other party by detecting the other party's signal. The present invention is characterized by comprising means for communicating by switching the communication device and communication method on the own side in accordance with the communication device and communication method on the other side.

Next, the operation of this device will be explained.

First, the operation when a call is received from the Gull facsimile communication device will be described. When a call comes in, the network control unit 1 detects a bell signal, answers the call, and outputs an incoming call detection signal to the line control unit 8. Also, turn on the switches 5a and 5b to connect the V27ter modem 5. When the line control unit 8 receives the incoming call detection signal,

27 Start monitoring the signal from ter modem 5. G
I[I In the case of facsimile communication, the calling party first sends 11
Since a signal of 00Hz is output, the 110011z detection circuit 2 is turned on. When the line control unit 8 detects this, it notifies the main control unit 9 that there is an incoming call from the GI[I facsimile, and also starts the communication control program from the GIII facsimile.
Switch to one for facsimile. In response to this, the main control unit 9 switches the processing program, and also
[Prepare to output the received image data to the facsimile device 13.] Thereafter, the line control unit 8 causes the network control unit 1 to control the switches 4a, 4b, 5a, 5b, 6a, and 6b, and connects the V21 modem 4 and the V27ter modem 5 or V2
9 Use either modem 6 to perform GI [facsimile communication.

Next, the case of the communication method recommended by the Ministry of Posts and Telecommunications personal computer communication equipment will be explained. In this method, data in a predetermined format called C3T is first output from the originating side. This can be detected as data by the V 27 ter modem 5. From the detection of the bell signal, 1100Hz detection circuit 2, 98011z detection circuit 3 and V 27 te
The process until the signal from the r modem 5 is monitored is the same as in the case of the G■ sofa simulator. In the case of the recommended communication method for PC communication equipment by the Ministry of Posts and Telecommunications, C3T is input as a signal from the V27 ter modem 5, so when the line control unit 8 detects this, it starts the communication control program using the communication method recommended by the Ministry of Posts and Telecommunications for personal computer communication equipment. main control unit 9.
Notifies you of an incoming call from a person using the communication method recommended by the Ministry of Posts and Telecommunications PC communication equipment. The main control unit 9 replaces the processing program and prepares to output data to the file device 12. After that, the line control unit 8 connects the V27ter modem 5
to perform data communication.

Next, the case of the V21 modem non-procedural communication system will be explained. 1100Hz detection circuit 2 after receiving a call
The process is the same as the above case until the signals of the 980 tl z detection circuit 3 and the V27ter modem 5 are monitored.

In the case of V21 modem non-procedural communication method, the 9 of the other party's modem
The 98011z detection circuit 3 is turned on by the 8011z signal. When the line control section 8 detects this, it notifies the main control section 9 that there has been an incoming call from the other party using the V21 modem non-procedural communication system, and also replaces the communication control program with one using the non-procedural communication system. The main control unit 9 replaces the processing program and outputs data to the file device 12.
Be prepared. Thereafter, the line control unit 8 uses the V21 modem 4 to perform communication.

If the line control unit 8 cannot detect any of the above signals, it determines that the other party is a voice. Then, an instruction is issued to the network control unit 1 to ring the bell of the telephone 7 without prompting the operator to answer the call. Note that this function can also be prohibited if necessary.

〔Effect of the invention〕

As explained above, the communication control device for automatically identifying the called party of the present invention identifies the sending side's communication device and communication method based on the signal received at the time of incoming call, and automatically selects the compatible communication device and communication method on the receiving side. It is a switch that can be made. Therefore, by using this device, even when one line is used for both facsimile communication and data communication using a computer, the communication device or communication method can be automatically switched. It is possible to improve work efficiency and save labor.
