Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for remote management of subscriber information files, in particular, a subscriber information file that stores information about subscribers accommodated in a subscriber line telephone exchange. This paper relates to a method for remote management of subscriber information files in a switching system that is centrally installed in a switchboard.

Management of subscriber information in this type of switching system is performed by the subscriber line telephone exchange that accommodates the subscriber. Conventionally, subscriber information is stored in subscriber information files that are centrally installed in trunk exchanges. Operations such as registration, changes, and deletions had to be performed from a maintenance typewriter attached to the relay exchange. Therefore, each time the subscriber information is registered, changed, deleted, etc., it is necessary for the maintainer of the subscriber line telephone exchange that manages it to contact the maintainer of the trunk exchange, and both maintainers are required to manage the information individually. There was also the possibility of inconveniences arising from dual management.

An object of the present invention is to eliminate the drawbacks of the conventional subscriber information file management method as described above, and to manage the subscriber information file installed in the relay exchange from the management source without going through the maintenance personnel of the relay exchange. The system allows maintenance personnel of subscriber line telephone exchanges to directly register, change, delete, and read subscriber information.

The purpose of this is to centrally install subscriber information files that store information about subscribers accommodated in subscriber line telephone exchanges in relay exchanges located higher up the exchange hierarchy. a first means for allowing readout, modification, registration and deletion of the subscriber information file from a qualified subscriber having a predetermined qualification accommodated in a telephone exchange; a second means for denying a connection request to the first means; and a third means for prohibiting the reading, modification, registration, and deletion of subscriber information files outside a predetermined range for each input/output terminal. This is achieved by providing

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
The figure is a diagram showing a subscriber information file remote management system according to an embodiment of the present invention. In the figure, subscriber line telephone exchanges EL0 and EL1 connect communication lines L0 and L to a trunk exchange TS located higher up the exchange hierarchy.
1. The file storage device FM in the trunk exchange TS is provided with a subscriber information file SF that stores information regarding the subscribers accommodated in the affiliated subscriber telephone exchanges EL0 and EL1. The subscriber information of the subscriber is stored in the area SD0, and the subscriber information of the subscriber accommodated in the subscriber line telephone exchange EL1 is stored in the area SD1. The file storage device FM also stores subscriber numbers N0 and N1 of subscribers who are qualified to access the subscriber information file SF among the subscribers accommodated in the subscriber line telephone exchanges EL0 and EL1. The area TN where is stored and the range in the subscriber information file SF accessible to the eligible subscriber
An area AA designated by SD0 and SD1 is provided. On the other hand, the subscriber line telephone exchange EL0 uses the subscriber information file SF in the trunk exchange TS.
A subscriber SUB0 that remotely manages subscriber information stored in an area SD0 is accommodated. The subscriber SUB0 is assigned a subscriber number N0 and has a telephone set.

As a result, the calling subscriber SUB0 passes through the subscriber telephone exchange EL0 (route 2) and the communication line L0 to the signal converter located in the trunk exchange TS.
Connected to FSOE. The calling subscriber SUB0 receives a confirmation tone (e.g. 1300
After listening to the Hertz signal tone), switch the switching device SW to the typewriter device TYP side, and type the access information including the access type (this time, changing subscriber information), subscriber number N2 to be changed, change information, etc. Input from writer device TYP. The access information is modulated into a voice band signal by the modem and transmitted to the signal conversion device FSOE via the subscriber line telephone exchange EL0 (path 2), the communication line L0 and the trunk exchange TS (path 4). be done. The signal conversion device FSOE demodulates the received access information using a built-in modulator and demodulator, converts it into a predetermined signal format, and then transmits it to the central processing unit CC1 via the communication line control device SPC1. The central processing unit CC1
compares the subscriber number N2 to be changed included in the access information and the area SD0 read from the subscriber number N0 corresponding section of area AA of the file storage device FM, and determines the subscriber number to be changed SUB2 (subscriber number N2).
