Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transmission system, and more particularly to a remote setting method for a data transmission apparatus for remotely setting software of the data transmission apparatus via a public telephone network which is currently most widely used as a line service.

[0002]

2. Description of the Related Art Conventionally, setting of software of a data transmission apparatus, that is, setting of a speed of a modem port, transmission timing, etc., is performed by connecting a console (a personal computer or the like) and inputting a command from a keyboard of the console. Or by operating the maintenance panel of the data transmission device.

[0003] In addition, the setting of a data transmission device existing in a remote place is performed by a person going to a remote place or by taking the data transmission device offline and using a data communication line between the terminal devices from a setting console. Was to do.

FIG. 3 is a block diagram showing a method of remote setting using this conventional data communication line.

[0005] The terminal device 1 is connected to a data transmission device 2, and is connected via a data communication line 3 to a data transmission device 4 to be set and a terminal device 5.

A setting console 6 is connected to the data transmission device 2. When remote setting is performed from the setting console 6, the data transmission devices 2 and 4 are taken offline,
The software of the data transmission device 4 was set from the setting console 6 through the data transmission device 2 and the data communication line 3 as shown by an arrow A.

[0007]

However, in the above-mentioned method in remote setting, there is a problem that if a person goes to a remote place and the system is changed frequently, the maintenance cost of the system becomes high. In addition, when a data communication line between terminals is used, it is necessary to stop online on an important line such as a financial system, which is often not permitted during business.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a data transmission apparatus provided with a modem interface unit to accommodate a modem, and using the modem, the data transmission apparatus is connected via a public telephone network. This is for remote setting of software.

[0009]

FIG. 1 is a block diagram showing an embodiment of the present invention. The terminal device 1 is connected to the target data transmission device 12 and the terminal device 5 to be set via the data transmission device 11 via the data communication line 3 such as a frame relay network.

The data transmission device 11 has a setting console 6
Is connected, and a modem, in the example shown, a modem card 1
3 are accommodated. Similarly, a modem card 14 is also accommodated in the data transmission device 12 to be set, and a setting console (not shown) is connected as necessary. The modem cards 13 and 14 are connected by a public telephone network 15.

When remote setting of writing of the data transmission device 12 is performed, the modem card 13 transmits a dial signal in accordance with a command (command) of the setting console 6, and the data is transmitted through the modem card 14 through the public telephone network 15. The transmission device 11 and the data transmission device 12 to be set are connected.

[0012] Here, for example, when a line of 2400 bps is created, the setting console 6 sends a password along the route of arrow B to confirm the other party, makes a write request, and sends data such as the speed of the modem port. The setting is performed, an OK signal is received from the data transmission device 12, the line is disconnected, and the setting is completed.

FIG. 2 is a block diagram of hardware in a data transmission device for enabling remote setting via a public telephone network using a modem.

The setting console interface unit 16
The bit string of the command received from the setting console 6 is converted into a command for the setting data communication control unit 17 to analyze, and the command received from the setting data communication control unit 17 is converted into a bit string for transmission to the setting console 6. It consists of a serial communication controller with functions.

The modem interface section 18 comprises an interface connector for accommodating the modem card 13 and a level converter circuit for electric signals.

The setting data communication control unit 17 is constituted by a microprocessor that analyzes commands received from the setting console interface unit 16 and controls the modem card 13 via the modem interface unit 18 as necessary. The control contents include line connection / disconnection control and transmission of data itself.

The device setting control section 19 controls the hardware in accordance with the contents of the setting, and is constituted by a microprocessor for controlling the hardware on / off in bit units.

Next, an example of the operation of each unit described above will be described. For example, when a dialing command (command) is input from the keyboard of the setting console 6 for remote setting, the setting console interface unit 16 that has received the bit string converts the bit string into a command and converts the command into a setting data communication control unit 17. Send to

The setting data communication control unit 17 analyzes this, and since it is dialing, the modem interface unit 1
8 to control the modem card 13 to call the data transmission device to be set, and the line is connected.

When the data transmission device shown in FIG. 2 receives a setting request from a remote data transmission device, the setting data communication control unit 17 sets the device setting control unit 19 according to a command sent from the modem card 13. Send the content,
The device setting control unit 19 controls hardware according to the setting contents and sets software.

[0021]

As described above, according to the present invention, since the data transmission apparatus accommodates the modem and performs remote setting via the public telephone network, it is possible to set or change the software of the data transmission apparatus without stopping online. It is possible.
