Abstract

PURPOSE:To attain the maintenance and operation of an exchange even in any remote location by using a facsimile converter so as to convert an operation management data generated by a central controller, using an automatic calling function and sending the data to the facsimile equipment at the maintenance side via a telephone network. CONSTITUTION:An input/output controller 14, a facsimile converter 15 and an interface trunk 16 are started from a central controller 13 at a time when a management and operation data is to be sent to apply the connection service of telephone exchange automatically via an office line trunk 17 to the facsimile equipment 3 accommodated to a telephone network 2 from the interface trunk 16. The operation management data generated by the central controller 13 is converted into a facsimile signal by the facsimile converter 15 and is sent to the facsimile equipment 3 via a generated path.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for remotely maintaining an exchange, and particularly to a system for remotely maintaining a storage program controlled exchange.

[Conventional technology]

Conventionally, this type of remote maintenance system connects an input/output control device and modem in a remote exchange and a modem and input/output device, such as a teletypewriter, on the maintenance side via a dedicated line. , the operation management data of the exchange was sent via the dedicated line route mentioned above to the input/output equipment on the maintenance side, and messages were printed and displayed.

[Problem that the invention seeks to solve]

The conventional remote maintenance system described above requires a dedicated line and a dedicated input/output device because it is remote, and the relationship between the remote exchange and the maintenance side input/output device is one-to-one. Since the switching equipment is operated and maintained at a specific location, it is not possible to freely change the location of operation and maintenance in a remote location, and it is expensive.

An object of the present invention is to provide a remote maintenance system that does not require a dedicated line, utilizes a telephone network, and can freely change remote operation and maintenance locations at low cost.

[Means for solving problems]

The remote maintenance system of the present invention is a remote maintenance system for an exchange that transmits operation management data generated by a central control unit of an exchange that is a storage program control type to a remote location. The present invention is characterized in that it includes means for converting into a telephone network and sending a call to a telephone network, and a maintenance facsimile device accommodated in the telephone network.

[Effect]

Therefore, according to the present invention, operation management data can be obtained via the telephone network using a facsimile machine that has recently become popular and has a standard interface. You can freely perform remote maintenance of the exchange from any remote location.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram showing an embodiment according to the present invention. As shown in FIG. 1, the storage program controlled exchange I11 is connected to a telephone network 2 such as a public line network via a central office line trunk 17, and a facsimile machine 3 is connected to the telephone network 2. has been done. Note that exchange ii is switch 119 and communication path control device 12. Central control unit 13. Input/output control device 14. Conversion device for facsimile 15. trunk 16 for service module interface;
Office line trunk 17. Extension°: ■ Consists of a talking device 18.

Extension telephone 6118 is connected to telephone network 2 via switch 111 and central office trunk 17 . The connection is made by the central controller 113 via the channel controller 12,
Telephone service is provided as a general private branch exchange.

The input/output 1III 11I device 14 is connected to the central control device 13, as well as the facsimile conversion device 15 and the trunk 1 for interface of the service module.
6 and is connected to switch 11.

Note that the operation management data of the exchange 1 handled in the exchange 1 includes data such as billing, traffic, failure, etc.
All these data are generated by the central controller 13.

These generated operation management data are sent to a facsimile machine 3 installed at a remote location, and its operation will be explained with reference to FIG.

At the time when the operation management data is to be sent, for example, at an arbitrary time in the program set in the central controller 13, or at the time when a failure occurs, the central controller 13 sends the input/output controller 14. Replacement for facsimile @15. Also, the interface trunk 16 is activated.

When activated, the interface trunk 16
For the facsimile machine 3 accommodated in the telephone network 2,
A telephone exchange connection service is automatically provided via the central office trunk 17.

When the facsimile machine 3 is called and answers, the interface trunk 16 is switched to the switch 11°81a trunk 17. Telephone network 2. A communication path is also formed to the facsimile machine 3.

Once the communication path is established, the operation management data generated by the central control device 13 is sent to the facsimile conversion device 15 via the input/output control device 14. The operation management data is converted into a facsimile signal by the facsimile conversion device 15 and sent to the facsimile device @3 via the communication path formed above.

[Effects of the Invention] As explained above, the present invention converts operational management data generated by a centrally controlled IT device using a facsimile conversion device, uses an automatic dialing function, and transmits the maintenance side's facsimile data via the telephone network. A facsimile machine, which has recently become popular and has a standard interface, can be used to transmit data to the equipment, and there is an advantage that the exchange can be operated and maintained at any remote location.
