Abstract

PURPOSE:To shorten the time required for package replacement and to prevent multijumber misconnection and command misinput by providing a switch between a wiring board and a corresponding line part and providing the corresponding line part with a spare package. CONSTITUTION:If a defective package 7 occurs, a spare package 9 is inserted. The interruption signal line of the spare package is made active by this insertion, and a common control part 10 controls a corresponding line part 5 through a bus not only to block the defective package 7 but also release the blocking of the spare package 9. The control part 10 controls a switch 4 through a switch control signal line 13 to connect an office extension 2 corresponding to the defective package 7 to the spare package 9. When the defective package 7 is removed and a normal package 8 is inserted, the common control part 10 is interrupted by the normal package 8, and this control part 10 controls the corresponding line part 5 not only to block the spare package but also release the blocking of the normal package. The control part 10 controls the switch 4 to connect the office extension 2, which is connected to the spare package 9, to the normal package 8.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention consists of a line support section for subscriber lines, and a common control section that performs interface control between the upper processor, the single line support section, and the upper processor. The present invention relates to a device, and more specifically, to a method for replacing a faulty package in a line corresponding section of the device.

(Prior Art) FIG. 2 is a block diagram for explaining a conventional example of a failure backing system for this Hagashi device.

A subscriber line 21 is connected to a distribution board 23 and is connected to a line corresponding section 25 via a one-office extension line 22.

The common control unit 30 is connected to the line support unit 25 and the upper processor 31.
Controls the interface between the

When replacing the faulty package 27't in the line correspondence section 25, first connect the faulty package 27 to the blocked normal package using the wiring fi 23' using multi-jumpers.

Next, the upper processor 31 closes the faulty package and unblocks the closed normal package that was previously connected with the multi-jumper.

After replacing the faulty package with the normal package 8, the normal package is closed and the normal package is unblocked. Thereafter, by removing the multi-jumper 34i, the replacement of the zipper compressor is completed.

(Problem to be Solved by the Invention) By the way, in order to operate as described above, the conventional failure package replacement method requires commands for connecting and removing multi-jumpers, blocking from the upper processor, and issuing a blockage release order money. It was necessary to make an investment.

Therefore, it takes time to replace the faulty package.

In addition, there is a drawback that a multi-jumper connection error or a command input error may occur.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks, and to provide a faulty package replacement method that reduces the total time required to replace a faulty package and eliminates the possibility of multi-jumper connection mistakes or command input mistakes.

(Means for Solving the Problem) Ninthly, the failure package replacement method according to the present invention achieves the above object. ! It is connected to the subscriber line through the panel and has a nine-line support section and a host processor.

In the failed package replacement method for a device comprising the line support unit and a common control unit that performs interface control with a host processor, etc., the connection #! All the switches are placed between the panel and the line support section, and the line support section is used as a spare package mounting section.

When a failure occurs in the normal package of the line correspondence section and a spare package is inserted, the line correspondence section sends an interrupt signal to the common control section marked #.

Upon receiving this interrupt signal, the common side am blocks the faulty package and unblocks the spare package,
Furthermore, when the switch is controlled to connect the intra-office line corresponding to the faulty package to the spare package, and the faulty package is removed and a normal package is inserted, the line handling section sends an interrupt signal to the common control section. , Upon reception of this interrupt signal 100, the common control section closes the spare package and completely releases the closure of the normal package, and further controls the switch to change the station s' connected to the spare package to the normal package. It is better to configure it than to connect to it.

('ii! Example) The present invention will be explained in more detail with reference to the following 11 items.

FIG. 1 is a diagram for explaining implementation of a failed package replacement method according to the present invention.

The subscriber line 1 is connected to the wiring 113, and the internal office line 2 housed in the distribution board 3 is connected to the line corresponding section 5 via the switch 4.

The line support section 5 has a large number of packages.

It has a part for mounting a spare package 9.

Among the many packages 15, it is assumed that there is a normal package gold 6 and a faulty package t7.

The spare package 9 is not inserted when no failure occurs.

The common control section IO is connected to the line correspondence section 5 and the host processor 11 via a bus.

The upper processor 11 issues a command to the common control unit 10.

There is also an interrupt signal line that becomes active when a spare package 9 or a normal package is inserted between the line correspondence section 5 and the common control section 10.

A switch 4t- is connected between the common control unit lO and the switch 4.
A switch control signal line for controlling is provided.

The replacement operation and device operation when a faulty package occurs will be explained.

If a faulty package 7 occurs, it must be replaced with a normal package, but for this purpose, the entire spare package 9 is first inserted.

When the spare package 9 is inserted, the interrupt signal line 12 of the spare package becomes active.

When the common control section 10 receives the interrupt signal, it controls the line correspondence section 5 through the node communication, and closes the faulty package 7t and unblocks the spare package 9. Furthermore, the switch 4 is controlled via the switch control signal line 13 to connect the internal line 21i corresponding to the failed package 7 to the spare package 9.

Next, the faulty package 7 is removed and the normal package 8 is inserted. This insertion causes the common control unit 10 to receive an interrupt from the normal package 8.

The common control unit IO supports the line via the path @! In control, the spare package is closed and the normal lock cage is unblocked. Furthermore, the switch 4 is controlled via the switch control edge 13t, which is connected to the standby switch cage 9 and connected to the normal switch cage 8 within the nine stations.

Thereafter, the replacement of the faulty package is completed by removing the spare package 9t.

(Effects of the Invention) As described above, the present invention provides a switch between the distribution board and the line corresponding part, and a spare package mounting part in each line corresponding part, so that when a spare package is inserted and a faulty package is removed, The common control unit is configured to control closing, unblocking, and switching in response to an interrupt signal generated when a normal package is inserted.

Therefore, unlike the conventional replacement method, there is no need to set multiple jumpers on the distribution board.9. Furthermore, since it is no longer necessary to input commands from the host processor, the time required for package replacement is reduced to VM, and there is an effect that multi-jumper connection errors and command input errors are eliminated.
