Abstract

PURPOSE:To receive one's own call while always using a nearby extension telephone set by giving a telephone number to each subscriber using a subscriber terminal set. CONSTITUTION:An extension user A loads an ID card 7 carried by the user storing one's own telephone number is loaded to an ID card reader 6 added to an extension telephone set 51 to input a telephone number to the extension telephone set 51. The extension telephone set 51 sends telephone number information inputted from the ID card 7 to a subscriber circuit 41, while the subscriber circuit 41 receiving the telephone number information informs the presence of request of station data change setting in a memory 2 to a central controller 1. When the central controller 1 identifies the subscriber circuit, the central controller 1 reads the telephone number information in the subscriber circuit 41 via a signal line 8. A subscriber circuit designation data in a table corresponding to the read telephone number is revised into a data designating the subscriber circuit 41.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an extension connection system in an electronic exchange that employs a storage program system, and particularly relates to an extension connection system that uses an individual numbering plan.

[Prior Art] Conventionally, in this type of electronic exchange, a telephone number is assigned to each accommodated extension or subscriber terminal corresponding to the extension, and station data including the telephone number information is Settings could only be changed from a specific dedicated terminal.

[Problems to be solved] In the conventional extension connection system described above, a unique telephone number is assigned to each extension housed in the electronic exchange or each subscriber terminal corresponding to an extension. , when making a call to a certain subscriber, the telephone number assigned to the subscriber's nearest extension is selected and dialed; If the subscriber is far away, the disadvantage is that the call cannot be made or that another subscriber must answer on his behalf and transfer the call to the nearest extension in another location where the subscriber is staying. Furthermore, if the nearest extension changes due to a subscriber's move, the telephone number assigned to the new nearest extension must be advertised to all other subscribers, or the telephone number assigned to the old nearest extension must be advertised. There was a drawback in that the maintainer of the electronic exchange had to change the station data via a dedicated terminal in order to reassign it to the new nearest extension.

[Means for Solving the Problems] The extension connection method in the electronic exchange of the present invention that solves the above-mentioned conventional problems is such that, in an electronic exchange that adopts a storage program method, an extension connected to the electronic exchange or a subscription corresponding to an extension is provided. A means for assigning a telephone number to each subscriber using a subscriber terminal, and inputting the telephone number previously given to each subscriber into the extension to which each subscriber wishes to receive calls or the subscriber terminal corresponding to the extension. And, in the electronic exchange,
This configuration includes means for reading out the telephone number input in advance into an extension or a subscriber terminal corresponding to the extension, and setting station data in the main body of the electronic exchange.

[Embodiment] Hereinafter, the present invention will be described in detail with reference to the drawings showing a preferred embodiment.

FIG. 1 is a block diagram showing an extension connection system in an electronic exchange according to an embodiment of the present invention. In this embodiment, a plurality of subscriber circuits 41, 42, etc. are accommodated in the switch network 3, and the central controller 1 has a memory 2 and controls the switch network 3 to execute telephone exchange connections. An extension telephone 51.52 is connected to each subscriber circuit 41.42, and at the same time an ID card reading device 6 is attached to the extension telephone 51.52. On the other hand, each extension user is individually assigned a telephone number, and each extension user carries an ID card 7 that stores his/her own telephone number.

If extension user A is currently staying near the extension telephone 51, extension user A will attach the ID card 7 that stores his or her telephone number to the extension telephone 51. Pass the ID card reader 6 through the extension phone 5.
Enter your phone number in 1. The extension telephone 51 transmits the telephone number information input from the ID card 7 to the subscriber circuit 41, and the subscriber circuit 41, which has received the telephone number information, sends the central control unit 1 to change the station data in the memory 2. Notify that settings are requested.

When the central control unit 1 identifies the subscriber circuit requesting the station data change setting, it reads out the telephone number information in the subscriber circuit 41 via the signal line 8.

The central control unit 1 that has read out the telephone number information stores it in the memory 2.
The subscriber circuit designation data in the table corresponding to the read telephone number in the extension search table 9 shown in FIG. Through these series of operations, all calls made to extension user A arrive at extension telephone 51.

Each extension user can always use the nearest extension telephone to receive and receive calls by performing the above operations on the extension telephone in the place where he or she is currently staying. It becomes possible.

[Effects of the Invention] As explained above, the present invention provides a telephone number for each subscriber who uses an extension connected to the electronic exchange or a subscriber terminal corresponding to the extension in an electronic exchange that adopts the storage program method. a means for each subscriber to enter the telephone number given in advance to the extension number or extension number corresponding to the extension number to which each subscriber wishes to receive calls; By having a means for reading out the telephone number that has been input in advance into the subscriber terminal and setting station data in the main body of the electronic exchange, the calling party can be aware of the place where the called party is staying. The caller can make a call without any hassle, and the caller can receive a call to himself or herself anywhere there is an extension or a subscriber terminal corresponding to the extension without disturbing other subscribers.

In addition, because subscribers can freely select and set the called extension or the subscriber terminal corresponding to the extension, the maintenance staff of the electronic exchange no longer have to set up and change station data. It is said to be effective in reducing workload.
