DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for a digital exchange, and more particularly to a remote control device for a digital exchange aiming at shortening a failure time when a failure occurs.

2. Description of the Related Art Most of the serious failures such as a system failure of a digital exchange are due to the failure of one system of the duplexer affecting the other system. It is a target. In order to control the power-off, it is necessary for the operator to go to the failure location and manually operate the device. However, in this conventional method,
It takes a long time to recover from a failure depending on the time required to move to the failure location.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method for dealing with a serious failure such as a system failure of a digital exchange.
It has been developed for the purpose of enabling the operator to control the power supply of the digital exchange by remote control without going to the location of the failure even when the power of the failed device is cut off as recovery means. At this time, if the power supply control of the digital exchange is performed by remote control, in order to prevent erroneous control due to the public nature of the system,
SUMMARY OF THE INVENTION It is an object of the present invention to detect a mistake in installation work, a wrong connection between a control device and a power supply device, and to prevent a wrong control.

According to the method of the present invention, there are provided each device of a duplex digital exchange, a remote control device connected to the digital exchange, and a control terminal connected to the remote control device. When the digital exchange is controlled by the control terminal, connection data registered in advance in the remote control device is transmitted to the control terminal in order to recognize whether there is an erroneous connection between the control terminal and the remote control device to be controlled. At this time, the connection data transmitted to the control terminal is configured to be continuously transmitted a plurality of times in order to recognize whether there is an erroneous connection between the control terminal and the remote control device to be controlled. In the method of the present invention, each device is provided with a duplicated digital exchange device, a remote control device connected to the digital exchange device, and a control terminal connected to the remote control device. In order to recognize whether or not there is an erroneous connection with the digital exchange, the identification data is provided on the frame of each digital exchange, the identification data is transmitted from the remote control device to the control terminal, and the management data recorded in the control terminal is compared with the management data recorded in the control terminal. By comparison, it was possible to determine the presence or absence of an incorrect connection with the digital exchange.
An apparatus according to the present invention is a digital exchange apparatus having a redundant power supply, a remote control apparatus connected to the digital exchange apparatus, and a control apparatus connected to the remote control apparatus via a communication line. A terminal is provided so that when a failure occurs in the digital exchange, the power supply of the digital exchange can be remotely turned off / on using a communication line. Further, the apparatus of the present invention is a remote control device for remotely turning off / on the power of the digital exchange using a communication line when a failure occurs in the digital exchange, and has a function equivalent to that of the power supply control of the digital exchange. With the use of the dedicated tester, the normal operation of the remote control device can be confirmed without using the digital exchange when the remote control device fails. This is because it is not possible to actually control the power of the digital exchange operated to check the normal operation of the remote control device. You can now check.

According to the present invention, there is provided a remote control device capable of remotely controlling the power supply using a communication line, and connection data is registered in the remote control device in advance so that the remote control device such as a personal computer can control the power supply. By transmitting connection data to the control terminal when connected to the control device, the control terminal determines whether or not the connection to the target remote control device has been established. Further, identification data is provided on a digital exchange that controls a remote control device to be connected, and the data is transmitted to a control terminal such as a connected personal computer. The control terminal has fixed management data of the connection device. Then, the presence / absence of an erroneous connection with the connection device is determined by comparing the transmitted data. Further, in the present invention, the function test of the remote control device can be performed without the need of a digital exchange by separately creating a dedicated tester.

As described above, according to the present invention, it is possible to provide a remote control device capable of preventing a double failure due to erroneous connection or erroneous operation. According to the present invention, the power supply can be remotely controlled by using the telephone line, and the failure time can be reduced as compared with the conventional method. In addition, by adding and managing connection data in the remote control device and the control terminal, an erroneous connection can be determined and a double failure can be prevented. Further, by providing identification data for each digital exchange to be controlled, the control terminal can recognize the connection device or the control device and determine the incorrect connection. Further, by performing the guard of the control device in the control terminal, the erroneous operation can be notified to the operator. By using the dedicated tester, the function test of the remote control device can be performed without affecting the digital exchange, and the normality of the remote control device can be confirmed.
