Abstract

PURPOSE:To implement data input output between a data exchange or a line concentrator and a network management equipment via a telephone line with a remote controller. CONSTITUTION:A telephone number to send monitor information and control information of a data exchange or a line concentrator 5 to a network management equipment 6 is registered in advance to a memory 1. When an alarm takes place in the data exchange or the line concentrator 5, it is stored in the memory 1 via a telephone line 7 and when setup of a phone call made to the network management equipment 6 is implemented, the alarm information stored in the memory 1 is sent to the network management equipment 6. When the maintenance personnel uses the network management equipment 6 to make a control request from data exchange or the line concentrator 5 to the controller 4, the controller 4 is controlled and the controlled result is read from the controller 4 and the result is sent to the network management equipment 6. Moreover, when the maintenance personnel makes a request from the network management equipment 6 to the data exchange or the line concentrator 5, the request takes over the data exchange or the line concentrator 5. Upon the receipt of a reply data from the data exchange or the line concentrator 5, the data is sent to the network management equipment 6.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control system for data exchanges and line concentrators in a data network.

0002

2. Description of the Related Art Conventionally, in a remote control system in which a network management device is used to remotely control data exchangers and line concentrators constituting a data network, a network management device is provided separately from the data exchanger.
The network management device exchanges monitoring information such as alarm monitoring information and status monitoring information, and control information such as restart instruction information, system switching control information, and remote diagnosis information via the data network. In particular, regarding power ON/OFF control, maintenance personnel go to the data exchange or line concentrator and turn the power ON/OFF.

0003

[Problems to be Solved by the Invention] As mentioned above, in the conventional remote control system for data exchanges and line concentrators, the network management device cannot control the data network due to a problem with the data exchanger in the data network or a line failure in the data network. It is not possible to transfer some or all of the monitoring information and control information of the data exchanger or line concentrator via the data exchanger or line concentrator, and the network management equipment maintainer has to perform alarm monitoring, status monitoring, etc. or restart instructions of the data exchanger or line concentrator. , system switching control, remote diagnosis, etc. may not be possible.

[0004] Furthermore, if the data exchanger or line concentrator is in unmanned operation, maintenance personnel must go to the data exchanger or line concentrator to turn the power on or off during holidays, etc., which is time consuming and wastes money. was occurring.

[0005]

[Means for Solving the Problems] The remote control system for data exchangers and line concentrators of the present invention uses a centrally installed network management device to monitor and monitor a plurality of data exchangers and line concentrators constituting a data network. In a remote control system for a data exchange and line concentrator that transmits and receives control information and remotely controls the data exchange, a remote control apparatus having input/output interface means and storage means for interfacing with the data exchange and line concentrator via a telephone line is provided, and the network management In order to transmit the monitoring information and control information to the device, the telephone number of the network management device is registered in advance in the storage means, and when the monitoring information is output from the data exchanger or the line concentrator, the telephone number is sent to the device via the telephone line. The received monitoring information is stored in the storage means, and in order to transmit the stored monitoring information to the network management device via the telephone line, a call is automatically made using the pre-registered telephone number, and the network management device then makes a call. receiving a monitoring/control request via a line, causing the data exchange or line concentrator to execute the received monitoring/control request, and receiving the result of the execution by the data exchange or line concentrator;
The configuration is such that the reception result is transmitted to the network management device via a telephone line.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of a remote control device showing an embodiment of the present invention, in which a plurality of data exchanges or line concentrators 5 (only one station is shown as an example in the figure) constituting a data network are connected to a network management device 6. The case of remote control via a telephone line 7 is shown. 2 and 3 are flowcharts showing the input/output processing procedure of the CPU in FIG. 1.

In FIG. 1, the remote control device is controlled by a central processing unit (hereinafter referred to as CPU) 2. As shown in FIG. CPU2 is
It is connected via the input/output interface 3 to a data exchange or line concentrator 5, a control device 4 that controls it, and a network management device 6 that manages the data network. The CPU 2 performs input/output data processing, and includes a memory 1 for storing its programs and various data.

Next, the input/output processing procedure by the CPU 2 will be explained with reference to FIGS. 2 and 3. A maintainer of the network management device 6 previously registers in the memory 1 a telephone number for transmitting monitoring information and control information of the data exchange or line concentrator 5 to the network management device 6. For example, when an alarm occurs in the data exchange or line concentrator 5 (step 21)
, is stored in the memory 1 via the telephone line 7 (step 22), and an automatic call is made to the pre-registered telephone number of the network management device 6 in order to send this alarm information to the network management device 6 (step 22).
Step 23). When the telephone call is set (step 24), the alarm information of the data exchange or line concentrator 5 stored in the memory 1 is sent to the network management device 6 (step 24).
Step 25).

[0009] When all the alarm information of the data exchanger or line concentrator 5 has been sent to the network management device 6, the telephone call with the network management device 6 is cut off (step 26), and the alarm management process is ended. When the call is not set as a result of step 24, timing is determined (step 27), and the process moves to step 23 in order to make a call again.

When the maintenance person makes a control request for the control device 4 from the network management device 6 (steps 28 and 29), for example, the data exchanger or the line concentrator 5 is turned on/off.
When performing control, necessary commands are sent via the telephone line to control the control device 4 (step 30), and the control results are read from the control device 4 and stored in the memory 1 (step 31). The information is sent to the network management device 6 (step 32), and the control process ends.

Furthermore, when the maintenance person makes a request from the network management device 6 to the data exchange or line concentrator 5 (step 29),
The request is delivered to the data exchange or line concentrator 5 (step 35), and when response data to the request is received from the data exchange or line concentrator 5 (steps 28 and 33), the information is stored in the memory 1 (step 3).
4), the process moves to step 32.

[Effects of the Invention] As explained above, the present invention makes it possible for a maintenance person of a network management device to monitor and control a data exchange or line concentrator due to a problem with a data exchange in a data network or a line failure in the data network. Turn on/off the power of the data exchanger or line concentrator during unattended operation when it is not possible or on holidays, etc.
When controlling the FF, there is an effect that monitoring and control can be carried out through a telephone line without going to the field.
