It is an object of the present invention to provide a station number storage method in a CENTRICS / ATTENT console device suitable for automatically transmitting a station number or an important station number in a guide of a DTS-1100A electronic switch.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

The information desk can provide the station number storage function to automatically transmit the frequently used station number or important station number, which can be stored up to 6, and the contents can be stored in the system (DTS-1100A Electronic Switching System). ) So that it can be managed in the system so that if the information is deleted due to an error in the guide, the guide will be able to receive the contents stored so far in the system and maintain them as the first time.

This may indicate the state before turning off the power included in the various initialization processes when the initial power-on.

Referring to FIG. 2, FIG. 2 is an algorithm according to FIG. 1, which is a flowchart showing step by step an embodiment of a station number storing method in a centric / attendant console device according to the present invention.

First, if you press the memory key, the lamp blinks every 1/1 second. At this time, input the number using the numeric keys. If you want to correct it, use the predetermined [BS] key. Press once.

At this time, the relevant lamp keeps lighting to display the station number storage, and also displays the key input status on the LCD (Liquid Crystal Display), and shows the completion message for a predetermined time (2 seconds) when the input is completed.

Next, when the number is input, the storage number (location) and the number data are transmitted to the system (electronic switchboard 200) to be managed.

In case of modifying the number, press the corresponding memory key (lamp 1/1 second blinks), use the [BS] key to correct it, input the number, and press the memory key once.

At this time, the data is sent to the system and if you want to delete it, use the [BS] key to delete all the numbers and press the memory key without entering the number.

In case of a call request using the stored number, press the corresponding memory key and press the [ACT] key to send the SETUP message to the system.

At this time, the lamp changes to the lit state and the stored state goes to the state before pressing.

And the call is normally made.

At the initial power-on, all the stored number data was received from the system before being powered off (the corresponding storage location and number).

It can be used without re-input because the previous state can be received from the system even when all the stored station number data is deleted due to an error in the guide.

That is, by checking the input key as shown in FIG. 2, it is determined whether the input key is a memory key (300, 310).

Next, when the key input in step 310 is not a memory key, a function according to the corresponding key is executed, and when a key input is a memory key, a set of memory key flags is determined (320, 330).

In step 330, if the key is not a key flag set but a numeric key, the corresponding lamp blinks, and the predetermined station number data is input and modified, the memory key flag is set, and the station number is set in the predetermined memory buffer. Store the data (340, 350, 360, 370, 380).

At this time, if the [ACT] key for the call attempt instead of the numeric key in step 340 described above, the corresponding call is attempted to make the call normally (390 and 400).

In addition, in step 330 described above, the corresponding lamp is turned on and the memory number and station number data is transmitted to the system side or the corresponding lamp is turned off according to the state of the memory buffer (CNT is 0) rather than the memory key flag set. The content is transmitted to the system side (410, 420, 430, 440, 450).

As described above, the present invention can store up to six desired station numbers in the guide of the DTS-1100A electronic switchboard, so that frequently used station numbers or important station numbers can be automatically transmitted and stored in the stored station numbers. There is an effect that makes it easy to dial the phone number.
