Here, reference numeral 100 denotes an MDF in a local telephone station and an unmanned station, and reference numeral 210 detects whether a trunk line connected to the main board 100 is disconnected, and as a result, when a disconnection trunk line is detected, a number corresponding to the disconnection trunk line is detected. The disconnection trunk line detection unit outputs data, and reference numeral 220 is connected to the disconnection trunk line detection unit 210 to control the display and alarm generation of the number data when the number data corresponding to the disconnection trunk line is transferred, and the remote management center and Represents a control unit that controls communication with laboratory personnel, and reference numeral 230 includes a program for controlling the overall operation of the automatic unattended remote alarm and display device, and fault data detected by a small and medium-sized exchanger in a local telephone station or an unmanned station. And a memory for storing the disconnected trunk line detection data and the telephone number by the call of the remote management center.

In addition, reference numeral 240 denotes an LCD display for digitally displaying the number data of the trunk line disconnected according to the number data display control of the controller 220, and reference numeral 250 denotes an alarm according to the alarm generation control of the controller 220. An alarm is generated and an alarm generator is configured to transmit the generated alarm signal to the speaker 260 to control the transmission to the outside. Reference numeral 270 denotes a telephone stored in the memory 230 according to a communication control of the controller 220. It performs the automatic dialing by the number and accesses the remote management center 300, and as a result of the connection indicates a communication unit for notifying the designated phone number of the trunk line disconnection status.

The operation of the automatic unattended remote alarm and display device in a local telephone station and an unmanned national company according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the automatic unmanned remote alarm and display device according to the present invention is connected to the MDF main board 100 in which a plurality of racks in a local telephone station and an unmanned station are combined.

In this state, the driving power is activated by supplying driving power to the automatic unattended remote alarm and display device, and the controller 220 initializes the device using a program stored in the memory 230, and displays the remote alarm and disconnected trunk line display. Start the control operation.

When the control operation is started, the disconnection trunk line detection unit 210 is connected to the main board 100 to automatically find the disconnection trunk line. That is, the signal lines of all columns of the distribution frame in the main board 100 are connected to the ends of the column self-checking boxes. The lower end of the self checking box is then connected to the self checking signal port. Therefore, it is possible to easily check whether the trunk line is disconnected.

When a disconnected trunk line is detected while checking whether the trunk line is disconnected, the trunk line number data corresponding to the disconnected trunk line is transmitted to the controller 220. Since a number is assigned to each trunk line, the disconnection trunk line detection unit 210 can transfer the number data corresponding to the trunk line which is easily disconnected to the controller 220.

When the number data for a specific disconnected trunk line is transmitted from the disconnected trunk line detector 210, the controller 220 applies a control signal to display the disconnected trunk line number to the LCD display unit 240, and receives the LCD. The display unit 240 digitally displays the disconnection line number on the LED. For example, when the MDF corresponding to 888 is disconnected due to overvoltage or lightning, the LCD display 240 displays the number data 888, so that the service personnel can easily recognize the disconnected trunk line later.

In addition, the control unit 220 transmits an alarm generation control signal to the alarm generation unit 250, and the alarm generation unit 250 which has received this generates an alarm, and transfers it to the speaker 260, so that the trunk line is disconnected. The alarm will be sent to the outside. In this case, if there are service personnel or managers in the vicinity, the alarm can be notified immediately by the alarm and notified to the laboratory personnel through the designated phone number. Will be prevented in advance.

On the other hand, the control unit 220 withdraws the contact phone number of the remote management center 300 stored in the memory 230, and transmits the retrieved phone number and a signal indicating the disconnection of the trunk line to the communication unit 270.

The communication unit 270 automatically dials the transmitted phone number through an automatic dialing function, and when an incoming call is made, the communication unit 270 transmits a signal indicating disconnection of the trunk line so that the administrator of the remote management center 300 easily manages the local telephone company and the unmanned station. Be aware of disconnection.

Then, the manager or service personnel of the remote management center 300 will visit the local telephone company and unmanned station for maintenance, and then accurately recognizes the disconnected trunk line displayed on the LCD display unit 240, and repairs the trunk line immediately. Subscribers will use the CO line immediately without any inconvenience.

This allows the manager or service personnel to reduce the time it takes to find a disconnected trunk line when the local telephone and unmanned trunks are disconnected, and provide a better service to the subscriber by quickly repairing the disconnected trunk line.

According to the present invention described above, there is an effect that can reduce the time required to find a disconnected trunk line at the time of disconnection of the trunk line due to overvoltage or lightning in the local telephone station and unmanned national history.

In addition, since it is possible to find the trunk line disconnected accurately and quickly, it is possible to relatively shorten the repair time of the trunk line, thereby providing a better service to the subscriber.
