Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission line extension method, and more particularly to a transmission line extension method for an online system that connects a subscriber device to an online device via a transmission line.

[0002]

2. Description of the Related Art In an online system in which a subscriber device is connected to an online device via a transmission line, the transmission line can be expanded in order to cope with the future increase in the number of subscribers. Then, when a new subscriber is to be accommodated, a transmission line is added.

Conventionally, such additional transmission lines have been added as shown in FIG.

That is, the administrator first of all, in step S41,
Place an order for the transmission line to be added. When the ordered transmission line is delivered in step S42, the transmission line is installed in the system (the transmission line is connected to the online device) in step S43. Then, step S44
Then, the performance is confirmed by conducting a diagnostic test of the transmission path installed in the system.

When its performance is confirmed by a diagnostic test,
In step S45, the maintainer uses the maintenance terminal connected to the online device to create a facility design drawing for managing the mounting / non-mounting of the transmission line on this maintenance terminal (the transmission line to be added is currently Addition to the facility design drawing). Next, in step S46, the maintenance person uses the maintenance terminal to
New device management data for managing implementation / non-implementation of transmission lines on the online device is created based on the facility design drawing, and the device management data on the online device is updated.

After that, if a device operation start command is input from the maintenance terminal in step S47, step S48
Then, the operation of the added transmission line is started. When the operation of the added transmission line is started, the online device updates the backup data of the device management data stored in the external storage device.

[0007]

The first problem is that the conventional method of adding a transmission line cannot immediately start operating the transmission line in response to an increase in the number of subscribers.

The reason is that in the conventional transmission line extension method,
This is because the transmission line is ordered only when the expansion is required.

Further, in this type of online system,
When the hardware or software failure in the system is detected, it is judged that the normal operation of the system cannot be maintained,
Although the program and device management data are taken over from the backup file, the system is returned to the initial state and is ready for operation again (system restart).
The backup data is updated after the operation of the new transmission line is started. Therefore, even if a transmission line is installed in advance, facility design drawings are created, and device management data is updated to immediately respond to an increase in the number of subscribers, the system restarts before the device operation start command is input. This is because when the occurrence of the above occurs, it is necessary to create the facility design drawing and update the device management data again, and it takes time before the operation starts. If the backup data is updated before the device operation start command is input in preparation for the system restart, if the system restart occurs, transmission without intention to operate (no subscriber accommodated) will be performed. Another problem occurs that the online device treats the road as being in operation.

It is an object of the present invention to provide a transmission line extension method capable of immediately responding to an increase in subscribers.

[0011]

According to the present invention, there is provided a transmission line extension method for an online system, wherein a subscriber device is connected to an online device via a transmission line, and after a new transmission line is connected to the online device, The holding status management information for designating hold / non-hold of the transmission path provided on the online device is set to the hold specified status to manage the new transmission path in the hold status, and the device operation command for the online device By putting the holding state management information into the non-holding designated state by inputting, the operation of the new transmission line can be started immediately after inputting the device operation command.

Further, according to the present invention, in a transmission line extension method of an online system for connecting a subscriber device to an online device via a transmission line, after a new transmission line is connected to the online device, the new device is connected to the online device. The device management information for managing the provided transmission line is updated, and the holding state management information for designating holding / non-holding of a transmission line different from the device management information is set to the holding designated state and the new transmission is performed. The device management information and the hold status management information can be backed up and managed when the system is restarted, and the management information and the hold information management information can be restored using the backup. In this way, by putting a device operation command into the online device, the holding state management information is set to the non-holding designated state. , Characterized in that the said rear unit operation command turned to begin immediately the operation of the new transmission line.

Further, the present invention is an online system having an online device capable of mounting a plurality of transmission lines, wherein the online device determines whether or not the transmission line is mounted by using device management data. The online device is provided with means for holding device hold state management data that specifies a hold / non-hold state of the transmission line different from management data, and the online device sets the transmission line based on the device hold state management data. The feature is that operation control is performed.

[0014]

[Function] Ordering, delivery, mounting, and diagnostic testing of transmission lines,
The facility design drawing is created and the device management data on the online device is updated in advance, and the holding status management data of the transmission path is set. Then, the backup data of the device management data and the hold state management data is updated. The online device recognizes the hold status of the transmission line based on the hold status management data. Therefore, if the device management data indicates implementation of the transmission path, but the hold status management data indicates suspension, the transmission path is not operated, and even if system regeneration occurs, the device management data The data can be maintained in the updated state, and the operation of the added transmission line is not started.

Further, since the device management data is in a state indicating the mounting of the transmission path, the operation of the transmission path can be immediately started only by changing the hold status management data to non-hold.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, an online system to which the transmission path extension method of the present invention is applied includes an online device 11 such as an exchange, a plurality of subscriber terminals 12, and a plurality of subscriber terminals each accommodating a plurality of subscriber terminals. Terminal 13 of
A transmission line 14 connecting each terminal 13 to an online device, a maintenance terminal 15 connected to the online device 11 for maintenance management of the online system, and an optical disk device for storing backup data necessary for the operation of the online system. And an external storage device 16 such as.

In this online system, the number of terminals 13 and transmission lines 14 is increased as the number of subscribers increases. That is, the online device 11 has many transmission line devices (not shown) for connecting the transmission line 14, and the transmission line 14 is connected to this transmission line device as needed. is there. In the following description, it is assumed that the transmission line 14 is connected to only some of the transmission line devices, and it is possible to add more transmission lines.

The online device 11 also includes a central controller 111 and a main memory 112. Then, the central control device 111 assigns an individual management number to the transmission path device and manages the mounting / non-mounting of the transmission path using this management number. That is, in the main memory 112, the device management data 113 indicating the mounting / non-mounting of the transmission path is written in association with the management number. Further, the central control unit 111 manages the hold / non-hold of the transmission path using this management number. That is, in the main memory 112, hold status management system data 114, which represents hold / non-hold of the transmission path, is written in association with the management number.

Furthermore, in preparation for the system restart, the external storage device 16 has the same data as the device management data 113 and the hold status management system data 114 written in the main memory 112 of the online device 11, that is, Backup data 161 and 162 are stored.

A method of adding a transmission line in this online system will be described below with reference to FIG.

First, in step S21, the maintenance person places an order for a new transmission line necessary for expansion. When the ordered transmission line is delivered in step S22, step S22
At 23, the transmission line is installed in the system.

Next, in step S24, the maintenance person performs a diagnostic test of the newly installed transmission line. When the test is completed, the maintenance person uses the maintenance terminal 15 to create a facility design drawing including information about the newly installed transmission line in step S25.

Further, the maintenance person creates new device management data based on the created facility design drawing, and the step S
26, the device management data 113 on the online device 11
To update. At this time, the maintenance person also registers the transmission path holding state for the newly installed transmission path. For example, as shown in FIG. 3, the information of the area indicated by the management number (primary management number and secondary management number) in the holding state management system data 114 stored in the main memory 112 is “holding”. This is performed by setting "=" 1 ".

Next, in step S27, the maintenance person determines whether to immediately start the operation of the added transmission line or to manage the added transmission line in a hold state. Then, if the operation of the added transmission line is to be started immediately, the process proceeds to step S28, the device operation command is input from the maintenance terminal 14, and the transmission line non-holding state is registered in the online device 11. This is, for example, the hold status management system data 114 of FIG.
The information of the area corresponding to the management number (primary management number and secondary management number) is set to “non-hold” = “0”.

When the hold status management system data 114 is changed to the "non-hold" status, the online device 11 immediately starts the operation of the added transmission line in step S29. The online device 11 then proceeds to step S28.
Then, the backup data 161 of the device management data and the backup data 162 of the pending state management system data stored in the external storage device 16 are updated.

On the other hand, when it is determined in step S25 that the added transmission line is to be managed in the hold state, the maintenance person specifies the fact to the online device 11 from the maintenance terminal 15. Upon receiving this designation, the online device 11 proceeds to step S30 without starting the operation of the added transmission line, and backups the device management data 161 and the hold state management system data stored in the external storage device 16. The backup data 162 of is updated.

The on-line device 11 indicates that the transmission line for which the holding state management system data 114 is in the "holding" state,
Do not operate while recognizing that the transmission path is installed. The operation start of the transmission line that is managed in the "hold" state can be performed at any time by inputting a device operation command from the maintenance terminal 14 and registering the transmission line non-hold state.

When the system is restarted while managing the added transmission line in the "holding" state, the backup data 161 and 16 stored in the external storage device 16 are stored.
2 is read into the main memory 112, but since the backup data 161 of the device management data has already been updated as described above, after the system is restarted as before,
You don't have to start over. Further, since the backup data 162 of the hold status management system data is also read, the "hold" status of the added transmission line can be maintained even if the system is restarted.

[0030]

The first effect is that it is possible to finish the transmission line expansion work in advance and to immediately start the service to a new subscriber.

The reason is that additional transmission is performed by using the hold state management system data for managing the hold / non-hold of the transmission path, which is different from the device management data for managing the implementation / non-installation of the transmission path. By making it possible to manage the path in a hold state and backup not only the device management data but also the hold state management system data, the hold state can be maintained even if the system restarts. Because.

The second effect is that the burden on the maintenance person can be reduced.

The reason is that the expansion work is not carried out in response to the request of a new subscriber, so that the expansion work can be carried out at an arbitrary time and it is not necessary to repeat the same work by restarting the system. .
