JPS62286395A - Terminal information storing system for isdn exchange - Google Patents

Abstract

PURPOSE:To allow a terminal equipment to be exchanged and added and to decrease the storage area of a storage part in an ISDN exchange by storing terminal information corresponding to the kinds of terminal at noncorresponding to terminals by allocating a file number at every kind of the terminal in the storage part in the exchange so as to set file numbers corresponding to the kinds of terminal at a terminal adapter side. CONSTITUTION:The terminal adapter 2 is provided to connect between the ISDN exchange 1 and the terminal equipment 3. A terminal-classified information file 11 is prepared to the storage part in the ISDN exchange 1 in noncorresponding to the terminal at every kind of the terminal, to give the file numbers to respective files. On the terminal adapter 2-side, by contacting with pulse effective key 22 and depressing pulse generation display button 21, an AND output from an AND circuit 23 is supplied to a pulse counter 24 to generate a pulse from the pulse counter 24. This pulse is made coincident with the file number of the terminal-classified information file 11 corresponding to the kinds of terminal coinciding with the terminal equipment 3, as well as stored in a storage circuit 25.

Description

DETAILED DESCRIPTION OF THE INVENTION [Detailed Description of the Invention and Field of Industrial Application] The present invention relates to a terminal information accommodating system in an ISDN exchange.

[Conventional technology]

Conventional ISDN communication 11! ! In the terminal information accommodating system in the exchange, terminal information is stored as subscriber data in a storage section inside the exchange as data corresponding to the accommodation location or destination number. .

[Problem that the invention seeks to solve]

In the terminal information accommodating method in the conventional ISDN exchange described above, it is common for the ISDN exchange system to accommodate commercial broadcasting terminals in the same accommodation position, and terminals under the same accommodation position can be freely replaced or added. Since there is a tendency for terminal information to be stored only in the storage section within the exchange for each terminal, it is difficult to communicate with other users. ! The disadvantage is that terminals cannot be replaced or added without the involvement of the machine.

Furthermore, storing terminal information in the storage section of the exchange according to the terminal 'I-=f has the drawback of requiring a storage area proportional to the number of terminals. An object of the present invention is to provide a method for accommodating terminal information in an ISDN exchange, which allows additions to be made and requires less storage area in a storage section within the exchange.

[Means for solving problems]

The terminal information accommodating method in the ISDN exchange of the present invention stores terminal information for each terminal type in the terminal type information file in the ISDN exchange, and
Take the logical product of the inputs from the pulse generation/display button on the terminal adapter that connects the N exchange and the terminal and the pulse enable key that validates or invalidates the input from the pulse generation/display button, and then calculate the logical product. The terminal adapter is configured to generate a pulse according to the result of , and store the pulse in a storage circuit of the terminal adapter as a file number corresponding to a terminal type that matches the terminal in the terminal type information file.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an ISDN switching system using one embodiment of the present invention.

As shown in FIG. 1, this embodiment includes an ISDN exchange file having a terminal type information file 11 therein, a pulse generation/display button 21, a pulse enable key 22, and an AND
A terminal adapter 2 including a circuit 23, a pulse counter 24, and a memory circuit 25, a terminal 3, and a network terminal 4 are combined.

The terminal type information file 11 is stored in a storage section in the T SDN exchange 1 for each terminal type, and a file number is assigned to each file.

On the terminal adapter 2 side, by touching the pulse enable key 22 and pressing the pulse generation/display button 21, the logical product output from the AND circuit 23 or the pulse counter 2
4, and a pulse is generated from the pulse counter 24.

This pulse is made to match the file number of the terminal type information file 11 corresponding to the terminal type that matches the terminal 3, and this pulse is stored in the storage circuit 25.

[Effects of the Invention] As explained above, the terminal information accommodating method in the ISDN exchange of the present invention stores terminal information that is not compatible with terminals and is compatible with the terminal type in the storage section of the I5DN exchange as a terminal type information file for each terminal type. You can easily set the file number corresponding to the terminal type under the terminal adapter by assigning a number and accommodating it, and by operating the pulse generation/display button on the terminal adapter side, it is possible to replace the terminal under the terminal adapter with another type of terminal. If the pulse generation
In some cases, this can be easily handled by simply resetting the file number by operating the display button.

In addition, on the ISDN exchange side, there is no need to store information according to the terminal type as subscriber data in the internal storage unit, so the storage area of the internal storage unit can be smaller than before, and the information according to the terminal type can be stored as subscriber data. This has the advantage that there is no need for maintenance.
