Abstract

PURPOSE:To set the suppression of an alarm at a remote place. CONSTITUTION:A provisioning setting part 3 which provisioning-sets channel units 11-1n in accordance with provisioning information transmitted from the remote place, a memory 4 where the validity/invalidity of provisioning setting is set and an alarm part 2 generating the alarm to the loading/unloading of the channel units 11-//-1n are provided. Furthermore, a register for alarm suppression setting 5 is provided and alarm suppression is set in the register 5 based on setting information on the validity/invalidity of provisioning setting. Thus, the will of the validity(IS: normal operation is possible) of provisioning setting for the channel units from the remote place or invalidity (OOS: normal unoperation) is decided, and alarm suppression can be set. Thus, a maintenance man does not need to go to the spot for altering the setting of alarm suppression as in the conventional manner.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm suppression setting method in a subscriber transmission device, and more specifically, a provisioning setting section for performing provisioning setting of a channel unit according to provisioning information sent from a remote location, and a validity setting of the provisioning setting. The present invention relates to an alarm suppression setting method in a subscriber transmission apparatus including a memory set to be invalid and an alarm unit for issuing an alarm for mounting / not mounting a channel unit.

Since many subscriber transmission devices are scattered in remote areas today, it is preferable that the maintenance personnel have to go as little as possible. Therefore, further remote control of such a subscriber transmission device is desired.

2. Description of the Related Art FIG. 3 is a diagram showing a configuration of a conventional subscriber transmission system. In FIG. 3, reference numeral 71 is a provisioning device having a console, CPU, etc. (not shown) for sending provisioning information remotely, and 72 is an RS232C.

FIG. 4 is a diagram showing the configuration of a conventional alarm suppression setting system for a subscriber transmission device. The same reference numerals as those in FIG. 3 indicate the same or corresponding parts, and 31 indicates data communication with the provisioning device 71. Data link processor (DL

Reference numerals 1 and 22 denote a plurality of AND gate circuits, and 23 denotes a NOR.
The gate circuit 24 is a light emitting diode for generating an alarm.

In such a subscriber transmission apparatus, it is necessary to provision a channel unit before operating a die group. In the provisioning, signaling of the channel unit and attenuation according to the subscriber line length are set from the remote provisioning device 71. In this setting, a state (state) is set as management information set in the memory 4. There is an item called. The state is valid (In Service: IS) / invalid (Out of Servic) of the contents of provisioning performed for the channel unit.
e: OOS), that is, the validity / invalidity of the provisioning content determines whether the channel unit can operate normally. In the case of IS, the channel unit can operate normally, and in the case of OOS, it operates normally. Not in operation.

On the other hand, in such a subscriber system transmission apparatus, it is judged that the channel unit of the die group is accidentally removed even though the channel unit is not intentionally mounted in the die group because it is not in operation. The alarm suppression setting function is provided to prevent the alarm from being generated. Conventionally, the alarm suppression is set by the DIP switch 7. For example, for the die group A for which the alarm suppression setting is turned ON, the AND gate circuit 21
Since one common input is LOW level, even if the other input of the AND gate circuit 21 to the channel unit 1 _A with the die group A corresponding by unimplemented becomes HIGH level, satisfying the NOR gate circuit 23 No, no alarm is issued. With respect to the die group B for which the setting is OFF, one common input of the AND gate circuit 22 is at the HIGH level, so that a certain channel unit 1 _B in the die group _B is not mounted and corresponds to A.
When the other input of the ND gate circuit 22 becomes HIGH level, the NOR gate circuit 23 is satisfied and an alarm is issued.

In this case, conventionally, while the channel unit is not mounted, or the channel unit is mounted but not in operation, the alarm suppression setting of the dip switch 7 is set to ON and the channel unit (die group) is set. ) Was set to OFF at the start of use.
However, since many of the subscriber transmission devices are scattered in remote areas, the alarm suppression setting must be changed at the start of operation, especially when there is a delay between the installation of the channel unit and the actual start of operation. Therefore, the maintenance person had to go to the site, which was very troublesome.

[0009]

As described above, in the conventional alarm suppression setting method for the subscriber transmission device, the alarm suppression is set by the DIP switch provided in the device, so that when the operation starts, the maintenance personnel Needed to go to the site to change the alarm suppression settings. An object of the present invention is to provide an alarm suppression setting method capable of remotely setting alarm suppression.

[0010]

The above problems can be solved by the structure shown in FIG. That is, according to the alarm suppression setting method in the subscriber transmission device of the present invention, the provisioning setting unit 3 for performing the provisioning setting of the channel units 1 ₁ to 1 _n according to the provisioning information transmitted from the remote.
And an alarm suppression in a subscriber transmission device including a memory 4 for enabling / disabling the provisioning setting and an alarm unit 2 for issuing an alarm for mounting / not mounting the channel units 1 ₁ to 1 _n. In the setting method, the alarm suppression register 5 is provided, and the alarm suppression is set in the register 5 based on the setting information of the provisioning setting valid / invalid.

[0011]

The alarm suppression setting method of the present invention utilizes state setting information in the remote provisioning setting, and is effective (IS: normal operation is possible) after provisioning setting for the channel unit. The alarm suppression setting is made in the register 5 based on the invalid (OOS: normal non-operation) setting information.

For example, when the state setting information for the channel unit of the die group A is IS (normal operation possible), by turning off the alarm suppression setting level of the corresponding storage element in the register 5, either When an alarm is generated due to the unmounted channel unit, and the state setting information for the channel unit of die group B is OOS (normal non-operation), the alarm suppression setting level of the corresponding storage element in register 5 is turned ON. By doing so, it is possible to suppress the generation of an alarm even if any channel unit is not mounted.

Therefore, it is possible to set a state item (decision decision) that is remotely valid (IS = normal operation is possible) or invalid (OOS = normally non-operation), and is also possible to set alarm suppression, which is the same as the conventional method even at the start of operation. There is no need for maintenance personnel to go to the site one by one.
