Abstract

PURPOSE:To improve the flexibility of central maintenance and operation of an exchange by connecting remote centralized maintenance operating devices so as to attain the transmission reception of a command. CONSTITUTION:When the maintenance personnel of a remote centralized maintenance operating device 1A requests the maintenance and operation of exchanges 9A1-9AP under its control to a maintenance operating device 1N in deputy, a deputy operation request signal addressed to the maintenance operating device 1N is sent from a terminal equipment 5 to a line 10. A deputy operation request reception section 4 of the maintenance operating device 1N receives the deputy operation request signal and a command discrimination section 3 makes an external command transmission section 6 operationable. In this state, with the maintenance operating device 1N inputting a maintenance operating command of the remote centralized maintenance operating device 1A from the terminal equipment 5, the maintenance operating command is sent to the line 10 and it is received by an external command reception section 8. Thus, the maintenance operation of the exchanges 9A1-9AP is attained from the maintenance operating device 1N.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote centralized maintenance and operation system for a switch that performs centralized maintenance and operation of a plurality of switchboards remotely.

[Conventional technology]

Conventionally, in this type of remote centralized maintenance and operation system for exchanges, only the exchanges that are directly connected to the own remote centralized maintenance and operation equipment are subject to maintenance and operation, and the maintenance and operation of exchanges that are connected to other remote centralized maintenance and operation equipment is not performed. could not be done.

[Problem to be solved by the invention]

In the conventional remote centralized maintenance operation method for exchanges described above, it is possible to maintain and operate only the exchanges directly connected to the own remote centralized maintenance operation equipment, and it is not possible to control exchanges connected to other remote centralized maintenance operation equipment. Therefore, maintenance operations of exchanges connected to the remote centralized maintenance operation equipment in the maintenance operation room, where maintenance personnel are absent, cannot be carried out as remote centralized maintenance, and a maintenance person must be assigned to each exchange. The drawback was that it lacked operational flexibility.

[Means to solve the problem]

The remote centralized maintenance and operation system for exchanges of the present invention connects a plurality of remote centralized maintenance and operation devices, each of which performs maintenance and operation of a plurality of switchboards under its control, through a line, and each of the remote centralized maintenance and operation devices is connected to another remote centralized maintenance and operation device. Transmitting/receiving means for transmitting and receiving requests for alternative operation from the maintenance and operation equipment, and a command that determines whether the input command is to be sent to the exchange under the own remote central maintenance and operation equipment or to another remote central maintenance and operation equipment. The present invention is characterized by comprising a determining means and a command transmitting means for transmitting a command determined by the command determining means to be sent to another remote centralized maintenance operation device.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, in this embodiment, N remote centralized maintenance operation devices IA, ~IN each have an internal command sending unit 2.
, a command determination section 3, an alternative operation request receiving section 4, a terminal 5, an external command sending section 6, an alternative operation request sending section 7, an external command receiving section 8, and an exchange 9A1.
It is connected to ~9AP and ~9N1 to 9NQ, respectively. Further, the remote centralized maintenance operation devices IA, -IN are connected to each other by a line 10.

Next, the operation of this embodiment will be explained.

For example, when requesting maintenance and operation of the subordinate exchanges 9A1 to 9AP to the maintenance and operation equipment IN because the maintainer of the remote centralized maintenance and operation equipment (hereinafter simply referred to as the maintenance and operation equipment) IA is absent, the above-mentioned maintenance A person sends an alternative operation request signal addressed to the maintenance operation device IN from the terminal 5 to the line 10 via the alternative operation request transmitter 7. In the maintenance operation device IN, the alternative operation request receiving section 4 receives this alternative operation request signal and transmits it to the command determining section 3. The command determination unit 3 determines that this signal is an alternative operation request from the maintenance and operation device IA, and puts the external command sending unit 6 into an operable state.

In this state, when a maintenance operation command for the maintenance operation apparatus IA is input from the terminal 5 in the maintenance operation apparatus IN, this maintenance operation command is sent to the line 10 via the command determination section 3 and the external command sending section 6. In the maintenance and operation device IA, the maintenance and operation command from the line 10 is received by the external command receiving section 8 and transmitted to the command determination section 3. The command determination section 3 determines that the maintenance operation command is an internal command, and transmits it from the internal command transmission section 2 to a designated exchange among the exchanges 9A1 to 9AP. Therefore, it becomes possible to perform maintenance and operation of the exchanges 9A1 to 9AP from the maintenance and operation device IN.

〔Effect of the invention〕

As explained above, the present invention connects remote centralized maintenance operation devices to each other to enable command transmission and reception.
Since it is possible to maintain and operate not only directly connected subordinate exchanges but also exchanges connected to other remote centralized maintenance and operation equipment, there is an effect that the flexibility of centralized maintenance and operation of exchanges can be increased.
