Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a package blocking method for blocking and unblocking a line package during maintenance and operation of an automatic switching device.

[Conventional technology]

In the conventional package blocking method, the line is blocked for each line package by operating a block key installed in each line package mounted on the frame or chassis, and the line is turned off by a predetermined initial setting operation. I was able to start it. The line package is implemented for each of multiple lines of line circuits for monitoring subscriber lines and trunk lines, sending and receiving signals, etc.

[Problem that the invention seeks to solve]

In the conventional package blocking method described above, a locking key etc. for the line package is installed at the place where the line package is installed, so maintenance operation requires going to the place where the line package is installed when blocking the line package. I had the above problem.

An object of the present invention is to provide a package i closure method that solves the above problems.

[Means for solving problems]

In the package blocking system of the present invention, the central control unit of the automatic exchange blocks or releases the package in accordance with the line designation and instructions from the maintenance terminal device. Therefore, the control section of the line package blocks and releases the lines accommodated and connected to the line package in accordance with instructions from the central control unit. The central controller instructs the package control unit in accordance with the instructions from the maintenance terminal device. The maintenance terminal device specifies all lines to the central control device and instructs the blockage and release of the lines.

〔Example〕

Next, the package closing method of 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 FIGS. 2 and 3 are flowcharts showing an example of the main operating procedures of the present invention.

In FIG. 1, the automatic switchboard has switch 1. LC package 2 and its control unit 3. 'rc package 4 and its control unit 5. The central controller 6 also has a maintenance terminal device 8 via an input/output controller 7.
Connect with. The switch 1 switches and connects the lines accommodated through the packages 2 and 4 under the control of the central controller 6. The LC package 2 accommodates and connects a terminal line, and is controlled by the control section 3 to block and release the terminal line.

The TC package 4 is connected to accommodate all the trunk lines, and is controlled by the control section 5 to block and release the trunk lines. The central control unit 6 is a central processing unit of an automatic exchange that mainly controls the switch 1, and its functions as an automatic exchange are the same as those of the prior art. The input/output control device 7 is a device for adjusting interconnection conditions for connecting input/output devices to the central control device 6, and connects the maintenance terminal device 8 as an input/output device. The maintenance terminal device 8 has a centralized maintenance function, and includes instructions for blocking and releasing lines.

Next, the main operating procedure in FIG. 1 will be explained with reference to FIG. 1 as well as FIGS. 2 and 3. First, when the operation manager specifies the package number and closure on the maintenance terminal device 8 and operates a closure instruction, the maintenance terminal device 8 issues a closure request to the central control device 6 via the input/output control device 7 . The central control device 6 constantly monitors information on package closure requests (
Operation procedure 1) and receives a blockage request from the maintenance terminal device 8 (
When the operator 1@2) is performed, the presence or absence of the package specified by the received information is checked by scanning (operation step 3). When the specified package exists (operation step 4),
The central control device 6 sends a reset order to the corresponding package, and also notifies the maintenance terminal device 8 to erase the "In operation" display provided on the package (operation procedure 5), and then sends a reset order to the corresponding package. The call connected to the accommodated line is released (operation step 6).

On the other hand, in operation procedure 2, when a request to start use of blockade is received instead of a blockage request (operation procedure 11), the central control unit 6 scans and confirms the presence or absence of the specified package (operation procedure 12). When there is a specified package (operator [13), the central controller 6 reads the initial setting data of the corresponding package from the storage device (not shown) (operation procedure 14) l.
, sends an initial setting command along with the read initial setting data to the control units 3 and 5 of the corresponding package (operation step 15)
do. The central control unit 6 waits until it has time to receive a command to complete the initial setting from the corresponding package, and then receives the command (operation step 16).

When the received command is normal (operator $17), the central controller 6 checks whether call processing for the corresponding package is possible (operator J@118). When call processing is possible (operation step 19), the central control device 6 notifies the maintenance terminal device 8 that call processing is possible for the corresponding package (operator JII 20).
Then, the maintenance terminal device 8 displays "In operation" for the corresponding package. On the other hand, if there is no designated package in operation steps 4 and 13, if the command is abnormal in operator [17], or if call processing is not possible in operation step 19, the central controller 6
notifies the maintenance terminal device 8 of the failure in processing the request (operation procedure 21), and issues “
"Processing failed" is displayed.

In the above embodiment, a means for blocking/unblocking a package has been described, but in reality, it will be used in conjunction with a display means for displaying the operating status of the package. That is, when the operation manager checks the operating status of the specified package using the display means, blocks/releases the package according to the present invention, and then checks whether the operating status of the package is as specified. The operation will be carried out according to the following procedures.

Further, information transmission and reception between the maintenance terminal device 8 and the central control device 6 is carried out by well-known means prepared for operating an automatic exchange.

Furthermore, it is obvious that the present invention can be implemented through a dedicated line or a public line by installing a modem or other modulation device between the maintenance terminal device and the input/output control device and installing the maintenance terminal device in a remote location. .

〔Effect of the invention〕

As explained above, according to the package≠blocking method of the present invention, the central control device installed in the automatic exchange transfers the instruction information of the maintenance terminal device to the package control unit, thereby blocking the package. Since it becomes possible to release the blockage from the maintenance terminal device installed separately from the automatic exchange without going to the location where the line package is installed, it is possible to improve the maintenance operation work.
