Accordingly, the present invention will be described in detail with reference to FIGS. 1-3.

Referring to the general functions of the main device KMS and the sub device KSS of FIG. 1, the main device KSS detects an incoming signal from the trunk line and transmits the incoming signal data to each sub device KSS. At this time, it not only announces incoming calls, but also transmits data to control various lamps. It also accepts various key data from KSS and provides services such as CO line calls and calls with other KSS. Perform. The sub-unit KSS receives various data from the main unit KMS, and turns on / off the lamp, that is, LED, turns on / off various beeps, checks the pressed key, and converts the input key data into the main unit (KMS). ) And receive various services from KMS. Referring to FIG. 2, the present invention will be described in detail with reference to FIG. 2, which is a flowchart performed by the first CPU 30 of the main unit KMS. The second central processing unit (80) of the KSS senses the switching state of the hook switch (88) so that the second interface (81), the transmission line (L1), the main subscriber circuit (40), and the first interface circuit (70). It is determined whether it is in voice call mode by inputting and checking the hook state data transmitted through the hook state data. If the hook state data is for the hook on state, it is determined as a man machine communication mode (hereinafter referred to as MMC) mode. On the contrary, if the hook state data is for the hook off state, it is determined as the voice call mode and set to the corresponding mode (step 200). In the step 200, the MMC mode is determined to be in the hook-on state, and in the setting state, the first CPU 30 scans the key metrics of the second CPU 80 and detects the key data in the second interface 81. And the speed dial key data is input through the transmission line L2, the main subscriber circuit 40, and the first interface circuit 70 to determine whether the speed dial number is stored (step 201).

As in step 200, the first central processing unit 30 always has a second central processing unit for a key input by the operator, and the first central processing unit 30 has an operator key as in step 201. Each time the matrix is manipulated, the key data sensed by the second CPU 80 scanning the key matrix 83 is transferred to the second interface 81, the transmission line L1, and the main subscriber circuit 40. Since the data is input through the first interface 70, the key data input process will be described below in the description of key data input. Then, in step 201, the first central processing unit 30 requests and stores the speed dial number. In step 203-205, the key data specifying a storage area for storing the public code information is input or secreted in step 203-205. By determining whether key data that designates a storage area for storing code information is input, steps 206-209 or steps 210-213 are performed. In step 201, the first central processing unit 30 inputs key data from the second central processing unit 80 to check whether the key data is one of a plurality of extension selection key data. In step 203, it is determined whether the storage area is designated for storing public code information.

When the key data input in step 203 is one of a plurality of extension selection key data, it is determined that the storage area for storing the public code information is designated, and in step 206 to step 209, the public code information input by the operator is inputted. It is stored in the corresponding storage area. Step 206 to step 209 is a routine process, and a detailed description thereof will be omitted. On the other hand, if the key data input in step 203 is not one of the plurality of extension selection key data, the first CPU 30 recognizing that the storage area for storing the secret code information is designated as RAM 20 In step 204, it is determined whether the current operator is the correct operator by reading the password stored in the terminal and comparing the password with the key data sequentially input from the second CPU 80.

If it is determined in step 204 that the password matches the correct operator, the second CPU 30 checks whether the key data input from the second CPU 80 is one of a plurality of extension selection key days. It is determined whether a storage area for storing secret code information is designated (step 205).

When the extension selection key data for designating a storage area for storing the secret code information is input in step 205, the first CPU 30 requests the speed dial message data to input the secret code information from the ROM 10. The second central processing unit 80 is read out and outputted to the second central processing unit 80 through the first interface 70, the main subscriber circuit 40, the transmission line L1, and the second interface 81. Allow the LCD display unit 87 to display the speed dial message and set a storage area and a first storage address for storing secret code information on the RAM 20 (step 210).

After performing step 210, the first CPU 30 sequentially stores the key data sequentially input from the second CPU 80 from the start storage address of the storage area set in step 210. In order to determine whether the speed dial number storage end request is made by checking whether the speed dial data is inputted from the second CPU 80 (step 211) while sequentially storing the data in the RAM 20 (step 211). .

When the speed dial key data is input in step 212, the first CPU 30 receives the address of the RAM 20 corresponding to the storage addresses other than the address where the new data is stored in the storage area set in step 210. The initialization message is read out from the ROM 10, and success message data indicating completion of storing the secret code information is read from the ROM 10, and the first interface 70, the main subscriber circuit 40, the transmission line L1, and the second interface are read out. Outputting the second central processing unit 80 to the second central processing unit 80 for a predetermined time to cause the second central processing unit 80 to display the success message through the LCD display for a predetermined time, thereby terminating the secret code information storage ( Step 213).

On the other hand, when the key data is input from the second CPU 80 in the state where it is determined and set to the MMC mode in the hook-off state in step 200, the input key data is input. It is determined whether the speed dial number transmission request is made by speed dial key data or check (step 202).

In step 202, when the speed dial number is requested to be transmitted, the first CPU 30 stores public or secret code information by performing steps 214 to 216, as in steps 203 to 205. In step 217 through step 220, the storage area designation of the public code information is performed by determining whether the key data to designate the zone is input. Description is omitted. On the other hand, when the storage area of the secret code information is designated in steps 214-216, the first CPU 30 sets the designated storage area (step 221) and then stores the data stored in the first address of the set storage area. Reads from the RAM 20 and checks whether a predetermined number (for example, 00FF) is stored to determine whether or not the secret code information is stored (step 222).

If the data read out from the RAM 20 in step 222 is not a certain number (for example, 00FF), the first CPU 30 stores secret code information in a storage area designated by an operator from the ROM 10. Read the "Good Message" data indicating the output to the second central processing unit 80 through the first interface 70 and the main subscriber circuit 40, the transmission line (L1), the second interface 81. 2 causes the central processing unit 80 to display the good message on the LCD display 87 (step 223).

After performing step 223, the first CPU 30 sequentially assigns the next addresses from the start storage address in the storage area set in step 221 to present data read from the RAM 20 in the service table. The secret code information is quickly dialed by storing the points in sequence (step 224), and it is checked whether the read data is a certain number, and the secret code information sending operation is terminated when a predetermined number of data is read.

When the passwords do not match in steps 204 and 215, or when the extension selection key data is not input in steps 205 and 216, or when the data read out in step 222 is a predetermined number of secret code information. If not stored, the CPU 30 reads out the error message data from the ROM 10, thereby providing the first interface 70, the main subscriber circuit 40, the transmission preference L1, and the second interface 81. By outputting to the second central processing unit 80 through the second central processing unit 80 causes the error message to be displayed on the LCD display unit 87 to terminate the operation (step 226).

As described above, the present invention corresponds to a single station selection key by mapping a storage area for public code information for storing a public dial number and a storage area for secret code information for storing a private dial number in a speed dialing operation. By deciding whether or not to select, the speed dialing can be performed in a state where a secret or private dial number is not leaked to a third party.
