BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of displaying MMC (Man Machine Communication) in an exchange system, and more particularly, to a method of arranging and displaying MMCs that are related to each other.

In general, MMC in the exchange system is used to change the program according to the function of the exchange system. However, since the exchange system includes many functions, when the user performs the conventional MMC, the user reads the manual and executes the MMC. However, this method has a problem that it is not known whether all the MMCs necessary to execute a function are performed.

Accordingly, an object of the present invention is to provide a method for easily programming a user's usable functions by displaying MMC numbers associated with each other on a display device when programming a function in an exchange system.

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

FIG. 1 is a system configuration diagram for carrying out the present invention, which shows the main configuration of a key telephone system. First, the CPU 11 controls the overall operation of the system, such as font status inspection of loops, rings, and digits, operation of call paths and relays for call control, call progress such as call formation and disconnection, signal processing, and diagnostics. And maintenance, handle MMC functions. The ROM 12 stores programs and initial service data for the CPU 11 to perform various functions. The RAM 13 temporarily stores various data generated during program execution.

The interface circuit 14 interfaces data between the CPU 11 and the call path components of the system. SCPU 15 is connected between keyphone subscriber circuit 16 and CPU 11. The SCPU 15 shares the work with the CUP 11 to control the data communication function between the key phone subscriber circuit 16 and the CPU 11, and corresponds to the class and all services of the key phone telephone. It has a backup RAM for storing data.

The key phone subscriber circuit 16 is connected to a key phone telephone and interfaces data between the key phone telephone and the SCPU 15 while interfacing a voice signal between the key phone switch and the switch circuit 17. The switch circuit 17 switches the communication path under the control of the CPU 14.

The trunk line circuit 18 is connected between the trunk line telephone line and the switch circuit 17 and interfaces signals and voice signals between the trunk line side and the key telephone system under the control of the CPU 11. A general subscriber circuit 19 is connected between a general extension telephone and the switch circuit 17 and interfaces voice and signals between a general telephone and a key telephone system under the control of the CPU 11.

The tone supply circuit 20 is connected to the switch circuit 17 and generates various tone signals under the control of the CPU 11. The DTMF receiver 21 is connected to the switch circuit 17, converts the DTMF signal received from the switch circuit 17 into digital data, and supplies the same to the CPU 11. The DTMF transmitter 22 is connected to the switch circuit 17, converts the digital data output from the CPU 11 into a DTMF signal, and outputs it to the switch circuit 17.

2 is a configuration diagram of a key phone subscriber, wherein the keyboard unit 32 generates MMC commands for registering and releasing various functions, commands for performing a registered function, and dialing data for performing a call. The controller 31 analyzes key commands and key data generated from the keyboard unit 32 to perform a corresponding function. The call path unit 33 is connected to the key telephone system to interface voice and signals between the key telephone system and the key subscriber. The display unit 34 displays the state of the key phone subscriber under the control of the control unit 31.

The above-described configuration of the telephone system and the subscriber of the telephone system of FIGS. 1 and 2 is a well-known configuration, and various processes for forming a call path are well known.

3 is a flow chart according to the present invention, when a specific button is pressed on the keyboard unit 32, the control unit 31 enters the MMC start state and is displayed on the display unit (LCD) 34. If a valid MMC number (00 to 99) is pressed, the control unit 31 displays the corresponding MMC contents in 34. FIG. Here, assuming that 00 is pressed by the keyboard unit 32, the control unit 31 checks whether the related MMC button has been pressed, and if not, jumps to a routine for processing the existing MMC of the control unit 31 by Handle MMC execution. When the MMC button is pressed on the keyboard unit 32, the related MMC selection state is entered. Pressing the volume button here displays the next number of the related MMC. If ff is found in the related MMC ROM table, the first related MMC is displayed. Pressing the Enter button jumps to the routine that performs the related MMC, processes the MMC, and checks if the related MMC button was pressed again after the MMC processing was completed.

4 is a table and point table diagram for each MMC function according to the present invention, where 4a is a table diagram of a related MMC and 4b is an example of a related MMC point.

That is, (4a) is a table of MMC numbers that are related to each other, and 00 to 99 on the left are offset values indicating MMC numbers, and the contents of the table indicate related MMC numbers. Extension lock MMC 00 is associated with the COS number change MMC 30 and also indicates the COS content change MMC 70. FF indicates the end of the associated MMC.

Change Password MMC 01 indicates that no MMC is involved.

(4b) is a pointer to the MMC to which the station currently in MMC is concerned and is as large as the competitor since all stations can play the MMC at the same time. The ROM table offset pointer is the offset value of the associated MMC ROM table that was first performed to view the associated MMC (for example, 3 is entered when the associated MMC button is pressed to view the associated MMC during MMC 03 execution). Save the location of the relevant MMC that is currently showing.

For example, if you execute MMC No. 02 and press the relevant MMC number, 2 is entered in the ROM table offset pointer and 0 is entered in the ROM table contents pointer. If you press the volume up button once, 2 is inputted in ROM table offset pointer, 1 is set in ROM table contents pointer, and contents of MMC 30 (COS number change MMC) are displayed on LCD. If you press the volume up button once more, table offset pointer 2 and ROM table contents pointer 2 are inputted, and the contents of MMC 70 (COS contents change MMC) are displayed on the LCD.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4, in step 2a, the input of a specific button key on the keyboard unit 32 is checked. When a specific button key is input in step (2a), the display unit 34 displays the MMC mode under the control of the control unit 31 in step (2b).

From the MMC mode display result of the processed display unit 34 in step (2b), at least in step (2c), input of a valid MMC number key indicated by the table function of FIG. 3A is awaited. When a valid key is input in step (2c), the corresponding MMC contents are displayed on the display unit 34 in step (2d). From the input of the valid MMC button key, (3a) checks whether it is the MMC button key input in the function table.

When the related MMC button key is input in step (2e), the control unit 31 processes the control unit 31 to display on the display unit 34 in step (2f). When the volume button key input from the keyboard unit 32 is checked in step 2g, the controller 31 controls the memory in step 2h to increase the ROM table offset point in FIG. Is displayed on the display unit 34, and again waits for the volume key input in step (2g) and waits for input of the enter key in step (2i). If there is an input in step (2i), only the process of processing the corresponding MMC in step (2j) is jumped. If the MMC has been processed, the process is executed again from step (2e). If the MMC has not been processed, the MMC process is processed.

As described above, when the user of the exchange system performs the MMC to perform a specific function, the MMC list related to the LCD of the key-phone telephone is displayed so that the function can be easily programmed.
