Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a diagram illustrating an arrangement state of each functional unit of a terminal configured according to the present invention, and includes a first function button 310, a second function button 320, a third function button 330, and a dial pad 340. A keypad 300, a display unit 350 for displaying information corresponding to a signal input through the keypad 300, a microphone 360 for inputting a voice signal, a speaker 370 for outputting a voice signal, and It consists of a handset 380.

In particular, the first function button 310 is configured to include buttons that can perform each trunk line function, extension function, shortcut function, speaker function, simultaneous call function, preliminary function, etc., the second function button 320 also As described above, it is configured to include buttons for performing different functions. Meanwhile, the third function buttons 330 are composed of buttons used to perform an operation on information displayed on the display 350.

4 is a detailed block diagram of the main device 500 constituting the key phone system according to the present invention and a relationship block diagram between the terminal 400 and the terminal 400 connected through the communication line. In particular, the main device 500 has an input / output control unit 510 which provides a passage for transmitting and receiving data with the terminal 400, and each function button on the keypad 300 during a communication session between the terminal 400 and the main device 500. RAM (RAM) for storing the information of the information, a program for controlling the operation of the terminal 400 and a ROM having a program for controlling the operation to be changed to the function of each function of the buttons on the keypad 300 (ROM 530 and each of the function buttons 310, 320, 330 of the keypad 300 during the communication session between the terminal 400 and the main device 500 display for a preset time. When the timer 540 for checking the operation time of the unit 350, the communication session between the terminal 400 and the main device 500 is requested, the above-described input and output control unit 510, RAM 520, ROM 530 and A central processing unit (CPU) 550 for controlling the function of the timer 540, respectively.

The input / output controller 510 in the main device 500 configured as described above is controlled by the central processing unit 550 to provide a data transmission path between the terminal 400 and the main device 500. Therefore, the input / output control unit 510, which is controlled by the central processing unit 550 and forms a transmission path between the arbitrary terminals 400 and the main device 500, services from an arbitrary terminal 300 connected through a telephone line or another communication line. When receiving the request signal, the CPU 550 transmits the received signal. The CPU 550 reads the information corresponding to the signal received from the input / output controller 510 in the RAM 520 and performs a corresponding function.

In order to change a function of a button on the keypad 300 of the terminal 400 which maintains a normal communication mode state, the terminal 400 needs to change a system program included in the ROM 530. This will require a system program change. The request signal is transmitted to the CPU 550 through the input / output controller 510. Since the central processing unit 550 is a signal for requesting a system program change, the CPU 550 controls the terminal 400 in the function button change mode while accessing the ROM 530.

When the user enters the extension number and the corresponding button number through the terminal 400 set in the function button change mode, the function change is performed for the corresponding function button. The change processing is performed by the central processing unit ( 550).

On the other hand, the RAM 520 stores an input number and a password for operating in the system conversion program mode state, and also stores an input number for releasing the system conversion program mode state. In addition, information of each function button, input number, and extension number of the terminal 400 is also stored in the RAM 520.

In order to access the RAM 520, the user presses a predetermined input number (predetermined number and symbol) through the dial pad 340 shown in FIG. That is, through the dial pad 340 [9] [9], [#] [9] [9], [5] [0], [#] [5] [0], [5] [1], [#] [5] [1], etc. can be applied as an input number. [9] [9] is a number for setting the system program mode, and [#] [9] [9] is the system program mode. Number to release. [5] [0] is a number used to add a CO button, [#] [5] [0] is a number used to release a CO button, and [5] [1] is an extension button. [#] [5] [1] is the number used to release the extension button.

Meanwhile, an embodiment of another method of the present invention will be described in detail with reference to FIGS. 6 and 7.

That is, FIG. 6 is a flowchart illustrating a process of processing information of a function button of each terminal 400 according to the present invention, and each terminal 400 always checks whether the button is operated and displays information on the operated button. 500). The main device 500 always checks information sent from various terminals 400. That is, when information for performing a predetermined function is input from the terminal 400 in operation 600 of FIG. 6, the CPU 550 proceeds to operation 610 and checks the signal of the pressed button. Read button information of the corresponding terminal 400 stored in). In operation 620, a signal for controlling the operation of the terminal 400 is transmitted based on the information read from the RAM 520.

The function change of the function button of each terminal 400 is performed as shown in the flowchart of FIG.

That is, in operation 700, the CPU 550 checks whether a user of any terminal 400 requests to change a function of a function button to another function. As a result of the check, if a change is requested, operation 710 is performed. In step 710, a code number input process transmitted from the terminal 400 is performed to set a system change program mode. As a result of the check in step 700, if the user does not request to change the function of the button, the routine shown in FIG. 7 is not performed.

In operation 720, the CPU 550 checks whether the system conversion program mode is set. As a result of the check, if the system conversion program mode is not set, the process returns to step 710. However, if it is determined in step 720 that the system conversion program mode is set, the process proceeds to step 730 and input processing is performed on the button number for changing the extension number and function of the corresponding terminal 400.

In operation 740, the input process is performed on the code number of the function to be changed. In operation 750, the changed function code of the corresponding button of the terminal 400 is applied to the corresponding area of the RAM 520. Is stored, and henceforth, the function of the above-described button is changed to perform the changed function.

The process of changing the functions of the buttons provided on each terminal 400 through this process will be described with reference to some examples.
