DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the main parts of an embodiment of a telephone system according to the present invention. In the figure, the telephone system according to an embodiment of the present invention includes a main device 1
, key telephones 8-11, and data terminals 16-19.

The main device 1 includes a main control section 2 that controls the entire key telephone, a storage section 3 into which data is read and written by the main control section 2, and a line interface 6 that accommodates the S/T point interface of the ISDN line. , and a button telephone interface 7. The storage unit 3 is
It has an incoming call memory 4 and a communication destination memory 5. The incoming call memory 4 is a memory that stores the destination of a call when the destination is not specified when a "call setting" notification is received. The communication destination memory 5 is a memory that stores a "calling number" and a "calling subaddress" when a "call setup" is notified from a calling side (not shown), and an invalid value is stored as an initial value. There is.

[0008] Key telephones 8, 9, 10, and 11 are connected to the button telephone interface 7, and data terminals 16, 17, 18, and 19 are further connected via data terminal connections 12, 13, 14, and 15. ing.

The button telephone 8 has a special button 81 for displaying data, a dial button 82 for normal use, a visual display 83 such as an LCD, and a data button 84 for selecting data. ing. It is assumed that button telephones 9, 10, and 11 also have the same configuration as button telephone 8.

FIG. 2 also shows a memory map of the communication destination memory 5. As shown in FIG. In the figure, the communication destination memory 5 is
Registration areas 51, 5 corresponding to telephones 8, 9, 10, 11 to which data terminals 16, 17, 18, 19 are connected, respectively
It is composed of 2, 53, and 54.

[0011] The registration area 51 also has a number memory 511.
, 512, 513, ..., 519, and the registration areas 52, 53, 54 are also number memories 521-5.
29, number memory 531 to 539, number memory 5
It consists of numbers 41 to 549.

Next, the operation of the telephone system of this embodiment having such a configuration will be explained with reference to the flowchart shown in FIG.

First, the key telephone 8 is stored in the incoming call memory 4 as the destination when a "call setting" without a "called party number" is notified.

[0014] When a "call setup" message is notified to the ISDN line, the information is notified to the main control unit 2 via the line interface 6. The main control section 2 recognizes the arrival of data, and thereafter starts processing according to FIG. 3.

[0015] First, the destination of the call is determined from the ``terminating number'' and ``terminating subaddress'' of the ``call setup'' message sent from the ISDN line. If there is no "called number" and "called sub-address", the key telephone 8 stored in the incoming call memory 4 is set as the called destination (process 31). The destination of the call here is the key telephone 8.

Then, the main control section 2 displays an incoming call to the data terminal 16 connected from the key telephone 8 via the data terminal connection section 12. Next, it is determined whether the "calling number" data in the "call setup" message, that is, the calling party number exists (process 32). When the "calling number" exists, the communication destination memory 5 corresponding to the button telephone 8
The "calling number" and "calling subaddress" extracted from the "call setting" message are stored in the number memory 511 of the registration area 51 of (processing 33). However, when a "call setting" message without a "calling number" is notified, no processing is performed (process 32→end).

[0017] Further, another "call setting" message with the "calling number" is notified to the main control unit 2 via the line interface 6, and the main control unit 2 determines that the key telephone 9 receives the call ( Process 31) and the number memory 521 of the registration area 52 of the communication destination memory 5 corresponding to the button telephone 9
The "calling number" and "calling subaddress" extracted from the "call setting" message are stored in (process 33).

Next, another ``call setting'' message with the ``calling number'' is notified to the main controller 2 via the line interface 6, and the main controller 2 again sends the button telephone 8 to the main controller 2.
When the incoming call is determined (process 31), the "calling number" and "calling number" extracted from the "call setting" message are stored in the second number memory 512 of the registration area 51 of the communication destination memory 5 corresponding to the button telephone 8. subaddress" is stored (process 33).

Similarly, when a "call setting" message is notified to the ISDN line multiple times, it is notified to the main control unit 2 via the line interface 6, and each time the destination of the call is determined,
The ``calling number'' and ``calling subaddress'' in the ``call setting'' are stored in the registration area corresponding to the destination button telephone in the communication destination memory 5.

[0020] Now, suppose that a "call setting" message including a "calling number" to which the key telephone 8 is the destination is notified three times, three number memories 51 in the registration area 51
Data is stored in numbers 1 to 513. That is, while the operator is absent, data will be stored in each number memory in sequence.

[0021] Here, when the button telephone 8 is operated, the main control section 2 starts a process of displaying data on the visual display 83. In other words, the operator performs the operation when he returns from going out.

When the special button 81 is pressed on the button telephone 8, the main control unit 2
Recognizes that the special button 81 has been pressed via
The registration area 51 of the communication destination memory 5 in the storage unit 3 is referred to. First, it is checked whether data is stored in the first number memory 511. When it is confirmed that the data is stored, the data in the number memory 511 is notified to the button telephone 8 via the button telephone interface 7 and displayed on the visual display 83.

When the special button 81 is pressed again, the main control section 2 checks whether data is stored in the second number memory 512. When it is confirmed that the data is stored, the data in the number memory 512 is notified to the key telephone 8 via the key telephone interface 7, and the data in the number memory 512 is displayed on the visual display 83. Similarly, display processing is performed for each number memory in the registration area 51.

Here, when the data in the number memory 513 is displayed, it is checked whether or not the data is stored in the next number memory 514. Since no data is stored here, the following number memories 514 to 519 are displayed. The process returns to the first number memory without checking. In other words, when the special button 81 is pressed multiple times, the number of data displayed on the visual display 82 is as follows: memory 511 → memory 512 → memory 513 → memory 5
11 → memory 512 →...

Next, the processing at the time of calling will be explained.

When the data in the memory 512 is displayed on the visual display 83 of the button telephone 8, the data button 8 is pressed.
4, the main control unit 2 sends a "call setup" message for data origination using the data in the memory 512 as the information elements of "called number" and "called subaddress" to the ISDN line via the line interface 6. Notice. That is, data transmission can be made from the button telephone 8 with a single touch to the number displayed on the visual display 83. In other words,
The operator can select data while checking the displayed content, and can send the data as is.

If you wish to delete the data stored in the number memory 512, enter a specific number from the dial button 82 while it is displayed on the visual display of the button telephone 8, and press the data button 84. do. At this time, when the main control unit 2 recognizes the dial information via the button telephone interface 7, the main control unit 2 stores the dial information in the number memory 512.
Perform the process of deleting the data.

The deletion process follows the steps below.

That is, the main control section 2 stores the number memory 51
3 is stored in the number memory 512, it is confirmed that the data is stored in the number memory 513, and the data in the number memory 514 is stored in the number memory 513. Next, it is checked whether data is stored in the number memory 514. Then, number memory 514
Since no data is stored in , the processing ends here. At this time, data is stored in the number memories 511 and 512 in the registration area 51.

[0030] In the above embodiment, if the user only wants to know about incoming calls when the user is absent, the selection/calling functions are not necessary.

[0031] Furthermore, although the case where the telephone system of the present invention is applied to an ISDN line has been described above, it is clear that the present invention can be applied to any line that has a function of notifying the number of the calling party to the called party. Yes, but not limited to.

[0032]

[Effects of the Invention] As explained above, the present invention provides an ISDN
When a data call is received from the line, by storing the caller's number in memory, you can know who the caller was when you were not available by displaying it on the visual display.
The effect is that you can send a message to that person with just one touch.
