Abstract

PURPOSE:To attain maintenance job by mounting a controller and a channel device or the like to plural modules decentralizingly and providing an input/ output device at each module to connect a maintenance terminal at each module. CONSTITUTION:An electronic private branch of automatic exchange 1 consists of four modules 1a-1d installed decentralizedly and a control system device and a channel system device as mounted decentralizedly to the modules 1a-1d. Input/output devices 2a-2d for connecting maintenance terminal to connect the maintenance terminals 3a-3d are mounted to the modules 1a-1d. Since the maintenance terminals 3a-3d and the exchange 1 are connected to each module via the input/output devices 2a-2d, the station data or the like of the exchange 1 is registered and revised near the modules 1a-1d. Further, one maintenance equipment is enough for one set of the exchange and moved to an installed location of the module as required.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a distributed maintenance terminal connection system for connecting a plurality of maintenance terminals in an electronic automatic private branch exchange system.

(Prior art) In a conventional electronic automatic private branch exchange system, one private branch exchange system is installed at one location within the premises, and an input/output device for connecting a maintenance terminal is installed at one location within the private branch exchange system. A centralized maintenance terminal connection method is generally practiced in which maintenance work is performed by connecting a maintenance terminal to a maintenance terminal.

FIG. 2 is a diagram showing an embodiment of a conventional electronic automatic private branch exchange system. In the figure, a private branch exchange device 5 is constructed by centrally installing a control circuit, a communication line system circuit, etc. A maintenance base input/output device 6 is installed in this device, and a maintenance terminal 7 is connected to the input/output device 6.

(Problems to be Solved by the Invention) Due to the advancement of technology and the diversification of needs, electronic automatic private branch exchanges are capable of connecting not only voice telephone terminals but also various data terminals of information processing equipment. transmission,
Exchanges are starting to take place.

Therefore, in order to keep the cables between the private branch exchange equipment and terminals as short as possible to reduce the transmission efficiency to $1, and to make effective use of floor space, it is recommended to install concentrated private branch exchange equipment in a decentralized manner. Conceivable.

The purpose of the present invention is to solve the following problems: When a single private branch exchange system is composed of a plurality of modules and each module is installed in a distributed manner,
Rather than performing maintenance work on private branch exchange equipment in one place,
It is an object of the present invention to provide a distributed maintenance terminal connection system that allows maintenance work to be performed near each module while checking the status of each module, the status of the nearby premises, etc.

(Means for Solving the Problems) In order to achieve the above object, the distributed maintenance terminal connection system according to the present invention is a maintenance terminal connection system for electronic automatic private branch exchange equipment, in which the control thread turn wt1 call system circuit, etc. A single horizontal switching system wt is constructed by distributing and mounting modules into multiple modules and connecting each module with an information transmission path, and each module is provided with an input/output device for connecting a maintenance terminal. The maintenance terminal can be connected to the input/output device of any module.

〔Example〕

Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like. FIG. 1 is a schematic perspective view showing an embodiment of a distributed maintenance terminal connection system for an electronic automatic private branch exchange system according to the present invention.

One electronic automatic S doubling exchange [(PABX) 1 is composed of four modules la to ld installed in a distributed manner. Control system devices and communication path system devices are distributed and installed in these four modules la to 1d. Each module is connected by a cable as an information transmission path.

Each module can be installed centrally at one location within the premises, but in the case of the present invention, in order to take advantage of its features, they are installed separately on each floor or in each department within the building. In other words, it is sufficient that the communication path equipment of each module satisfies the number of terminals for each floor or the number of terminals for each department.

Each module la to 1d has a maintenance terminal (MAT) 3a.
-3d Maintenance terminal connection personnel equipment i (Ilo PKG) 2a to 2d for all connections are installed.

This allows input/output devices 28 to 2d for each module.
1, the maintenance terminals 3a to 3d and the exchange device l can be connected via the exchange device vjL near each module 1a to 1d.
1 station data etc. can be registered and changed.

Of course, these maintenance devices 3a to 3d are W! Since it is possible to connect to modules other than the installed module and register and change necessary station data, only one maintenance device is required for each exchange device, and the module can be moved to the installation location as necessary.

(Effects of the Invention) As explained above, the present invention distributes and mounts a control device, a communication line device, etc. that constitute one exchanger fit into a plurality of modules, and mounts an input/output device for each module. This configuration has the advantage that switching equipment can be installed in a distributed manner within a premises, and maintenance work can be performed by connecting maintenance terminals to each module.
