JPH04217140A - Remote work control system for switchboard - Google Patents

Abstract

PURPOSE:To attain the remote control of the switchboard work by analyzing the work control information based on the health check answer signal received by a network controller and controlling the work history as well as the transmission of a fault alarm. CONSTITUTION:When the construction is carried out to the subscriber circuit of a packet terminal 5-2, the start or the end of the work is inputted through the terminal 5-2 together with the circuit number inputted through an external switch 4-1 of a packet network switchboard 4 respectively. The switchboard 4 produces a work control frame where a packet number, a work control information valid/invalid flag, a work start/end flag, and a circuit number are set based on the input information and adds the control frame to a health check answer signal. Then the work control frame is transmitted to a network controller 1. The controller 1 analyzes the given work control information to recognize the construction to be carried out. Then the controller 1 control the transmission of a fault alarm to a maintenance terminal 5 and also registers a work start/end history.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a network management device that collectively manages the line status and operating status of the exchange in a packet switching network by a health check method between the exchange and the network management device, and in particular, the present invention relates to a network management device that collectively manages the line status and the operating status of the exchange in a packet switching network, and in particular, the present invention relates to a network management device that collectively manages the line status and the operational status of the exchange in a packet switching network using a health check method between the exchange and the network management device. It relates to a remote work management method in which input is input and managed by a network management device.

2. Description of the Related Art Conventionally, in this type of remote work management system, there was no means for inputting work management information from the switchboard where work was performed, and recognition was performed by maintenance personnel inputting work management information from a maintenance terminal.

0003

[Problems to be Solved by the Invention] In the above-mentioned remote work management system, management information for work including line work cannot be input from the exchange, but is input from the maintenance terminal, so the maintenance terminal is separated from the work place. If it is installed in a
There is a drawback that the maintenance person has to go to the maintenance terminal and input work management information.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote work management system for an exchange that allows work information on the exchange and line construction to be registered from the exchange without using a maintenance terminal.

[0005]

[Means for Solving the Problems] The remote work management system for an exchange of the present invention has a network management device, and uses a health check method between the exchange and the network management device to check the line status in the network and the usage status of the exchange. In a remote work management system for switching equipment in a packet switching network to be monitored and controlled, there is provided a means for inputting work information during expansion work, line work, and maintenance inspection work in the network, and a method for determining a required frame configuration from the input work information. The exchange includes means for generating work management information, and means for adding the work management information to a health check response signal returned in response to a health check signal periodically transmitted by the network management device, means for extracting and analyzing the work management information from the health check response signal received by the management device; means for regulating the output of fault alarms generated in the analyzed exchange and line of sight; and means for managing the work history. It is characterized by being equipped with the following functions and managing within the network.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a frame structure of work management information added to a health check signal.

[0007] The remote work management system of the switching equipment shown in FIG. Ru.

[0008] Here, an example will be explained in which construction is carried out on a subscriber line (indicated by a dotted line) connecting the packet network exchange 4 and the packet terminal 5-2.

The network management device 1 includes packet network switches 2, 3,
4, periodically the signals 10-2, 10-3, 10-
4, and if the packet network switches 2, 3, and 4 are normal, health check response signals 20-2, 20-3, 20-
4 is returned from the packet network switches 2, 3, and 4 to monitor the operating status of the switches.

When construction is to be carried out on the subscriber line of the packet terminal 5-2, the start or end of the work and the line number are input from the packet terminal 5-2 through the external switch 4-1 of the packet network exchange 4. The packet network switch 4 sets the packet number (PSNO), work management information valid/invalid flag (WF), work start/end flag (SE), and corresponding line number (CN) from the input information as shown in Figure 2. A work management frame for the health check response signal is generated, added to the health check response signal, and transmitted to the network management device 1. The hair management sochi 1 recognizes the construction work to be performed by analyzing the work management information added to the health check response signal, and regulates the sending of failure alarms of the corresponding line that occur after that to the maintenance terminal 5, Register the history of start/end of work.

[0011]

[Effects of the Invention] As explained above, the present invention allows work to be registered in the network management device from the exchange that performs the work.
Even if the maintenance terminal is located at a remote location from the work site, the construction worker does not have to travel to the maintenance terminal each time. Therefore, there is an effect that there is no need to install a maintenance terminal in each exchange just for the purpose of registering work.
