Abstract

PURPOSE:To attain an unattended maintenance station by transferring automonous message data and remote command data by the No.7 signal system. CONSTITUTION:A remote control function as a user section of a signal connection control section (SCCP) is provided to a common line signal interruption exchange of stations 1, 2 and a remote control command is set in addition corresponding thereto. An automonous message outputted by the maintenance station 2 is outputted to a monitor test seat 4 of the station 2 and a line 5 tying the exchange is used by using the SCCP and transferred to the station 1, and then outputted to a monitor test seat. The remote command applied by the station 1 is transferred similarly by using the SCCP to the station 2 and the reply message being the result of execution is outputted to the test seat 3 of the station 1 by using the SCCP. Thus, the remote maintenance is implemented at the central maintenance station without revision of the system configuration of the maintenance station to realize the unattended maintenance station.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote maintenance system for unmanned maintenance of a single-sided common line signal relay switch in a quasi-correspondence network common line signaling network having a duplex structure.

[0002]

2. Description of the Related Art Conventional remote maintenance has been performed by extending a monitoring test seat of a station to be maintained to a central maintenance station via a modem line.

FIG. 2 shows a conventional remote maintenance system. The autonomous message issued by the station to be maintained 2 is output to the monitoring test seat 4 of the station to be maintained 2 and the modem 24,
Monitoring test seat 26 installed in central maintenance station 1 via 25
Is output to.

Further, the maintenance command is input from the monitoring test seat 26 installed in the central maintenance station 1, and the modems 25 and 2 are provided.
Executed by the station to be maintained 2 via

[0005]

In the conventional remote maintenance system, one of the two monitoring test seats, which should originally be installed in the station to be maintained, is installed in the central maintenance station via a modem line or the like. Therefore, there will be no spare monitoring test seat at the station to be maintained.

When the maintenance test station installed in the maintenance station fails during the time when the maintenance person is working at the maintenance station, the command from the central maintenance station is issued even if there is a maintenance person. It is irrational because it has to be input.

It is an object of the present invention to provide a remote maintenance system that can perform remote maintenance only when necessary without damaging the system configuration including the standby system of the station to be maintained.

[0008]

In order to achieve the above object, a remote maintenance system according to the present invention is a remote maintenance system in which a maintenance station is remotely maintained by a central maintenance station. A remote control function is added as a user unit of a signal control unit to a common line signal relay exchange installed in a quasi-correspondence network common line signal network that adopts a duplex configuration provided between, and a remote control command is set, Command,
The maintenance of the common line signal repeater exchange is performed from the terminal of the remote common line signal repeater exchange using the line connecting the common line signal repeater exchanges of each maintenance station.

[0009]

[Function] Using the line between the common line signal repeater exchanges of the central maintenance station and the maintenance target station, the autonomous message data from the maintenance target station and the command data from the central maintenance station to the maintenance target station are sent to No. Transfer by 7 signal system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, the central maintenance station 1 and the maintenance target station 2 are already equipped with a common line signal relay switch installed in a quasi-correspondence network common line signal network having a duplex configuration. In addition, No. It is connected via a line 5 using a 7-signal system.

In this embodiment, an existing common line signal repeater exchange is used. That is, a remote control function is provided to the common line signal relay exchange of each station 1 and 2 as a user unit of a signal control unit (SCCP), and a remote control command is set and added correspondingly.

The autonomous message issued by the station to be maintained 2 is output to the monitoring test seat 4 of the station to be maintained 2 and is connected to the common line signal relay exchanges by using the remote control function of the signal connection control unit (SCCP). It is transferred to the central maintenance station 1 using the line 5 and is output to the monitoring test seat 3 of the central maintenance station 1.

The remote command input from the central maintenance station 1 is also transferred to the station to be maintained 2 using the signal connection control unit (SCCP), and a response message indicating the execution result is sent to the signal connection control unit (SCCP). Is transmitted to the centralized maintenance station 1 and is output to the monitoring test seat 3 of the centralized maintenance station 1.

[0015]

As described above, according to the present invention, the central maintenance station can perform remote maintenance without changing the system configuration of the maintenance station, and the maintenance station can be unmanned.

Claims (1)

[Claims] 1. In a remote maintenance system in which a maintenance target station is remotely maintained by a central maintenance station, it is installed in a quasi-correspondence network common line signaling network adopting a duplex configuration provided between the maintenance target station and the central maintenance station. A remote control function is added to the common line signal repeater exchange as a user unit of the signal control unit, a remote control command is set, and a line connecting the common line signal repeater exchanges of each maintenance station is used by using the command. Then, the remote maintenance system is characterized in that the maintenance of the common line signal relay exchange is performed from the terminal of the remote common line signal relay exchange.
