When a key for entering the MMC mode is input, if the input ID is a missed announcement message change MMC ID, a new message information is received by receiving a notification message number to be changed. It is determined whether the first character and the special character indicating the end of the message after the first process is performed. If the special character is not the special character, the new absence message is input in the first process. A second process of registering as a guide message and a third process of determining whether to continue to change the next guide message number after performing the second process, and returning if not changed, and receiving a guide message number to be changed in the first process if the change continues. The process takes place.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1-5 based on the above-described configuration.

First, in the central processing unit 20 of the main unit 1 of FIG. 1, is the absent key indicating absence in step 3A (1A) input from the key-phone telephone and the digital telephone 2 through the subscriber access circuit unit 30? Check it. At this time, if the absent key is not input in step (1A), the CPU 20 returns to the beginning again, but if the absent key is input, it performs step (2A). In step (2A), the central processing unit 20 checks whether it is already in the absence mode, and if it is already in the absence mode, branches to step (3A) to release the absence mode and returns to the beginning. If it is not in the absent mode in step (2A), the central processing unit 20 performs step (4A) to display the first missed guide message among the missed guide number messages of the key phone and the digital telephone (2). Display on LCD (Liquid crystal display). After performing step (4A), the central processing unit 20 checks whether to select the out-of-office guidance message displayed on the LCD in step (5A), and if selected, sets the out-of-office mode in (6A) (7A). Follow the steps. At this time (7A), the central processing unit 20 registers the selected out-of-office guidance message number in the storage table of FIG. 2A and branches to step (8A) to give a confirmation tone to the user. And return. If the user did not select the guide message displayed on the LCD in step (5A), the CPU 20 checks whether the missed guide message number displayed in step (9A) is the last. At this time, if it is determined that the message is the last message in step (9A), the CPU 20 returns to step (4A) to repeat step (4A), and if it is not the last message, step (10A). Performing again, the missed guidance message of the next number is displayed on the LCD of the key-phone telephone (2), and then returns to the step (4A) again to perform the step (5A) again.

In FIG. 2A, the OUTSTAT is a register indicating whether or not the user is in the absence mode. The OUTSTAT is composed of one byte and indicates whether the subscriber is in the absence state. The message number (MSG-NO) is used to inform why the user is absent when in the out of office mode. The message number is selected from among the out-of-office guide messages and stores data corresponding to the number. . The guidance message (GUID-MSG) stores the actual guidance message, and the length and number of the guidance messages may vary depending on the type of LCD and the characteristics of the system mounted in the key phone telephone and the digital exchanger 2, but the present invention recognizes them. The length of the message is limited to 16 characters and explained. Assuming that the LCD mounted on the key phone 2 has 16 columns, the maximum length of the message is 15 characters, the length of the missed announcement message is 16 bytes, and the last 1 byte indicates the end of the message. Character is placed.

Figure 2b shows the actual storage of the missed announcement message, '2' in the outstat (OUTSTAT) represents the missed mode, message number (MSG-NO) '04' 'OUT TO LUNCH of the announcement message 4 For example, this means that you are absent because you are now out for lunch. The EOM of the announcement message N is a special character indicating the end of the announcement message as an end of message (END OF MESSAGE).

4 is a flow of performing an out of office guidance service using a guide message as shown in FIG. 2B. First, when subscriber A calls subscriber B in step (1B), the central processing unit 20 rings the subscriber B. Send a call to the subscriber B, and then perform step (2B) to check whether the subscriber B is in a hook on state, and if it is not in the hook on state, terminate the hook on state (3b). Diverge. At this time, the central processing unit 20 checks whether the subscriber B is in the absence mode in step (3B) and terminates if it is not in the absent mode, and if it is in the absence mode, the tone generator 50 is transmitted to the subscriber A in the step (4B). ) To hear the chords. After performing the step (4B), the CPU 20 reads the missed announcement message number registered in the message number MSG-NO of FIG. 2B from the memory 10 in step (5B). After interpreting the data, an address in the memory 10 in which the actual guide message is stored is obtained, and then step (6B) is performed. At this time, in step (6B), the absence guidance message corresponding to the address is read in sequence from the memory 10 and displayed on the subscriber A's LCD. Step 7B is performed to check whether the final value is a special character (EOM) indicating the end of the message. If the data indicates the end of the message, the method returns to step (6B) and the special character indicating the end of the message. If (EOM), exit.

5 is a flowchart of changing the table of FIG. 2B. First, in step (1C), the central processing unit 20 checks whether a key for entering the MMC mode has been entered, and terminates if it is a key for entering the MMC mode. If not, branch to step (2c) to check whether the inputted key data is the missed announcement message change MMC ID. At this time, if the MMC ID input in the (2c) is the missed guidance message change MMC ID, the central processing unit 20 branches to step (3c) and receives the message number to be subsequently inserted in step (4c) Receive a new missed message. In step (5c), it is checked whether the data input in step (4c) is special character data representing the end of the message. In step (5c), if the data input in step (4c) is a special character, (7c) is performed by registering the content of the absence guide message received in step (6c) as a new out of office guidance message. At this time, in step (7c), the central processing unit 20 continuously changes or checks the next missed guidance message number, and if it is changed continuously, performs step (3c) again and returns if it is not changed.

As described above, the present invention records the absence guide message when the key phone and the digital phone user are absent and displays the absence guide message on the LCD of the calling party subscriber even if a call is received from the subscriber. This has the advantage of reducing frustration and allowing you to take appropriate action in your work relationship.
