Abstract

PURPOSE:To reduce job man-hour by adopting the line number setting in which an ISDN(Integrated Services Digital Network) line number is obtained by down- loading it for the setting system. CONSTITUTION:A notice section 5 of a 1st notice equipment 1 makes a call to a 2nd equipment 10 at the rising of the system or the like to inform an ISDN line number 21 registered through the contact with an ISDN network in advance through a D-channel. Then a line number setting section 20 of the 2nd equipment stores the informed line number 21 to a setting memory 15, and thereafter the 2nd equipment 10 references the setting memory 15 to make dialing to the 1st equipment 1. Thus, the line number setting by the 2nd equipment 10 is not required by allowing the 2nd equipment to down-load the line number 21 from the 1st equipment 1.

Description

[Detailed Description of the Invention] [Summary] The present invention relates to a line number setting method. In a system in which the first and second devices are connected by 15DNlii and both parties make calls to communicate with each other, the first device a notification unit provided in the second device and configured to notify the second device of the registered I5DN line numbers of the first and second devices via the D channel;
and a line number setting unit that sets the notified line number in a setting memory, the first device calls the second device to notify the line number, and the second device thereafter receives notification of the line number. The system is configured to make a call to the first device based on the line number.

[Industrial application field]

The present invention relates to an improvement in a line number setting method in a system using an 15DN network.

In recent years, ISD N (Integral 5erv)
Centralized monitoring and control systems using ICEs Digital Networks are becoming popular.

Conventionally, in centralized monitoring and control systems using public lines,
Data is exchanged by making calls from the data generating side each time, but in a system using the 15DN network, a call is established when the system is started up, and data is exchanged while the line remains connected. is used.

For this reason, it may be configured such that the center always makes the call, but in order to speed up the establishment of the call, a two-way call system in which both parties make the call is often used.

Therefore, it is necessary to set the line number necessary for making a call in each device to be monitored, but the conventional method of setting it in hardware for each device requires a large number of man-hours.

Therefore, a simple line number setting method is required.

[Conventional technology]

FIG. 3 is an explanatory diagram of the prior art.

Figure 3 shows the automatic transaction equipment installed at each branch.
This figure shows an example of a centralized monitoring and control system that performs monitoring and control at a center via a DN network.

The branch system includes multiple automatic transaction devices (W), 16 telephones (1)
7. It is composed of a surveillance camera 18 and the like, and a terminal adapter 31 performs call control and control based on D channel data.

The center has a central monitoring and control device3. A telephone, a monitor 6, etc. are provided, and the central monitoring control device 3 sends control information to the automatic transaction devices 16, etc. of each branch, and displays on the console 2 the status information of the automatic transaction devices 16 sent from each branch. Also, the monitor 6 displays video information from the surveillance camera 18 for intensive monitoring.

And the branch side system and the center side system are
They are connected to the 15DN network via respective DSUs (house network termination units), not shown, and exchange of monitoring and control information is performed.

In this system, once a call is established, the line remains connected until one side is turned off, but in order to improve the efficiency of establishing a call, a method is used in which both parties make calls. The line numbers required when making a call, that is, the center line number and the branch line number, must be set on both the center and branch sides, respectively.

Therefore, when building a system, the center uses console 2.
The line number is input and registered in the central monitoring control device 3, and is set in the setting board (or non-volatile memory) 32 at the branch office.

[Problem to be solved by the invention]

As explained above, the line number for making a call from the branch device has been manually set in hardware on the setting panel 32 or the like of the branch device. As a result, the number of man-hours required for setup is large, and in particular, when the line number is changed or when starting up a backup device with a different line number, it is necessary to go to each branch office and reconfigure the line number. There are challenges.

In view of the above problems, it is an object of the present invention to provide a simple line number setting method that facilitates line number setting in a system using an 15DN network.

[Means to solve the problem]

In FIG. 1, a diagram of the principle of the present invention, in the first device 1, 5 is a notification unit that makes a call to the second device 10, and calls the 15DN line number 21 assigned to each of the first and second devices. is notified via the D channel.

Further, in the second device 10, 14 is a line number setting unit that stores the notified line number 21 in the setting memory 15.

15 is a setting memory.

[Effect]

At the time of system startup, etc., the notification unit 5 of the first device I makes a call to the second device 10, and makes a call to the L5DN line number 21 (hereinafter referred to as line number) that has been contracted and registered with the L5DN network in advance.
is notified via the D channel.

The line number setting unit 14 of the second device stores the notified line number 21 in the setting memo January 5, and from now on, the line number setting unit 14 of the second device
calls the first device 1 with reference to the setting memo January 5.

As described above, by downloading the line number 21 from the first device 1, the line number setting work on the second device IO becomes unnecessary.

When constructing the system, from the console 2, the center device 1 and each branch device 10a such as branch A, branch B, etc.
10b line number 21 is input, and the central monitoring control device 3
The information is registered in a non-volatile memory (not shown) included in the computer.

Note that the line number 21 of each device is also registered in the backup device 7 in the same manner.

In the centralized monitoring and control system configured as described above, the following line number setting process is performed at the time of system construction or system startup when changing the line number.

(1) After turning on the power, the notification unit 5 of the center device 1 refers to the line number 21 of each registered device and first calls the device 10a to the branch office.

(2) When a call is received from branch A in response to this call, the notification unit 5 notifies the line number 21 of the center device 1 and the device 10a of branch A using the D channel.

(3) In the terminal adapter 11 that has received and identified the line number notification, the line number setting unit 14 stores it in the setting memory 15.

The above setting process is sequentially performed for each branch.

(4) From then on, every time the power is turned on, the call control unit 13 calls the center device 1 by referring to the line number 21 of the center device 1 and its own device set in the setting memo January 5. .

When switching to the backup device 7, the backup device 7 notifies the line number 21, and the branch office similarly sets this in the setting memo January 5 and uses it for call control.

As described above, since the line number 21 is downloaded from the center device 1, there is no need to set the line number 21 at the branch office.

In addition, in the example, a supervisory control system was used as an example, but 1S
Of course, the present invention can be applied to other systems connected to the DN network.
