The memory unit 12 includes a ROM for storing program and service data and a RAM for temporarily storing data generated during program execution. The clock circuit 14 generates current time data as the clock chip IC and outputs the current time data to the CPU 10. The switching circuit 16 swings various tones and voice data under the stirring of the central processing unit 10. The general subscriber circuit 18 supplies a call current to a general telephone (not shown) under the control of the central processing unit 10 and at the same time interfaces the signal between the general telephone and the switching circuit 16. The ring generator 200 generates a ring signal and supplies it to the subscriber line. The key phone subscriber circuit 22 transmits and receives various data with the key phone telephone KP under the control of the central processing unit 10, and supplies a call current. And interfacing a signal between the cut-off keyphone telephone KP and the switching circuit 16. Here, the keyphone telephone KP and the general telephone become an extension subscriber, and the general subscriber circuit 18 and the key subscriber circuit 22 are connected. The tone generator 24 generates various tone signals under the control of the CPU 10 and outputs them to the switching circuit 16. The trunk line circuit 26 ) Controls the central line to control the trunk line to form a trunk line call loop, and interfaces signals between the trunk line and the switching circuit 26. Here, the trunk line refers to the trunk line circuit 26. ) And local exchange A DTMF receiver 28 analyzes a DTMF signal input from the switching circuit 16, converts the DTMF signal into digital data, and outputs the digital data to the central processing unit 10. Here, the DTMF signal received by the switching circuit 114 to the DTMF receiver 28 may be a telephone number generated by the trunk line subscriber or a telephone number generated by an extension subscriber. The digital data output from the central processing unit 10 is converted into a DTMF signal and output to the switching circuit 16.

In the present invention, a multifunction key is implemented in the keyphone system as shown in FIG.

First, by using the MMC (Man Nachine Communication) function of the key phone telephone (KP) to be used to store all the functions of the memory unit 12 of the key phone system as well as the purpose of the key. Then, several multi-keys that perform the same functions as the purpose of the key are set according to the purpose. The multifunction key is made of the following keys (1)-(5) and used for the corresponding purpose.

(1) Key K1: Allows the user to keep changing the purpose of the desired key.

(2) Key K2: Allows you to temporarily change the usage of one key only once.

(3) Operation key: activates the key state displayed by the key K1 pressed by the user.

(4) Assigned key: Allows the user to keep the purpose of a key that has been changed only once by key K2.

(5) Designated Hacker Key: The user can release the key to be used as the designated key and change it to the initial (unique) key.

The numeric key or function key provided in the key phone KP is used as a unique key initially set unless there is control through the multifunction key. However, key functions to be performed by the control by the key K2 are assigned to each key (numeric keys or function keys) one by one.

When the multifunction key as described above is implemented and registered in the memory unit 12 of FIG. 1, the operation according to the present invention is performed as shown in FIG. 2.

Referring now to FIG. 3, the central processing unit 10 determines whether the key data corresponding to the key K1 of the multifunction keys is pressed in step 100. If the key K1 is pressed, the key function set data is read from the memory unit 12 according to the number of times the key is pressed and displayed on the display unit of the key phone telephone KP. Therefore, if the user keeps pressing the K1 repeatedly, when the user presses the operation key while all the function states stored in the memory 12 are displayed, the CPU 10 detects the step 104 and proceeds to step 105. To perform the key service in the indicated state.

On the other hand, if the key K2 of the multi-function key is not pressed in step 100 and the key K2 is pressed, the CPU 10 detects it in step 106 and proceeds to step 112. However, if the fraud key K2 is not detected in step 106, the method proceeds to step 108 to detect whether the general key is pressed, and then proceeds to step 110 to perform a corresponding key function.

If the process proceeds from step 106 to 112, the CPU 10 determines whether a predetermined key whose function setting has been preset is pressed, or terminates the process and proceeds to step 114 when the predetermined key is pressed. The central processing unit 10 reads the function state preset for the predetermined key from the memory unit 12 and displays it to the user in step 114, and the user will select the key function to use the key function once. The once-use key selection is performed by pressing the previously pressed key again. If the user presses the up key again, the central processing unit 10 services the function of the setting function key only once in step 116.

If the user wants to continue using the service function only once, the user presses the designated key. If the user presses the designated key, the central processing unit 10 proceeds to step 120 and can continue to serve the service function only once. Repurpose it so that However, if the designated key is not input in step 118, the CPU 10 proceeds to step 122 to terminate the one-time set function key service and change the predetermined key that has been pressed to the initial set key function state.

On the other hand, when the user changes the usage to the setting function key in step 120 and wants to return the predetermined key to the initial state, the user presses the designation release key. The central processing unit 10 determines in step 124 whether the designation release key is applied, and if detected, proceeds to step 122 and returns the used key to the initial setting key function.

As described above, the multi-function key implementation of the present invention can be applied anywhere in a communication system having a key, and various changes and modifications can be made without departing from the spirit of the present invention. Self-evident to those who have

As described above, the present invention can use all the service functions desired by the user without additional equipment in the communication system using only the keys in the terminal device, so the user does not need to purchase additional equipment so that the user can reduce the cost and the terminal. All users who use the service, such as connected to the additional equipment has the advantage of increasing the convenience of use.
