In FIG. 1, the main devices of the button telephone device of this embodiment include a button telephone interface 3 accommodating button telephones 11 to 1n, and an I interface 3 accommodating ISDN lines 21 to 2m.
An SDN 877-point interface 33, a communication path switch 32 that forms a communication path between the key telephones 11 to 1n and the ISDN lines 21 to 2m or the key telephones 11 to 1m, and a main control unit 34 that controls the entire device. A program section 35 that stores programs for the main control section 34; an incoming call control program section 36 included in the program section 35; a memory section 37 that stores data for the main control section 34; and an incoming call control memory section 38.

FIG. 2 is a diagram showing a memory map of the incoming call control memory section in this embodiment shown in FIG.

Next, the operation of this embodiment will be explained using FIG. 1 and FIG. 2 together.

First, when registering data in the incoming call control memory unit 38, the user dials a special number for registering the extension number of the incoming call, using the key telephone 11, for example. This information is sent to the main controller 34 via the button telephone interface 31. Based on this information, the main control section 34 searches for an empty area in the incoming call control memory section 38 and makes a reservation for registration. Next, using the button telephone 11, dial the telephone number of the calling party to be registered (hereinafter referred to as the calling number). This information is sent to the main controller 34 via the key telephone interface 31. The main control section 34 stores this information in the calling number storage area of the reserved area of the incoming call control memory section 38, as shown in FIG.

Next, dial the extension number from the button telephone 11 that you wish to receive a call from. This information is available at Button Phone Interface 3.
1 to the main control unit 34. The main control unit 34 stores this information in the destination extension number storage area of the reserved area of the incoming call control memory unit 38. Repeat this operation,
All necessary calling numbers are registered in the incoming call control memory section 38.

Next, when the ISDN S/T point interface and 33 call setup information comes from the ISDN line 21, this information is sent to the ISDN S/T point interface and 33 main control unit 34, The main control section 34 transfers control to the incoming call control program section 36. The incoming call control program section 36 reads the first calling number (1) from the incoming call control memory section 38 and compares it with the calling number in the "call setup" information. If the results match, the destination extension number (1
) and starts incoming call processing for the key telephone of the extension number. If they do not match, the incoming call control memory section 3
Read out the calling number (2) after 8. This process is repeated until the last calling number (X) in the incoming call control memory section 38.

If the calling number does not match all of the calling numbers in the incoming call control memory section 38, incoming call control is performed on all key telephones 11 to 1n.

As another embodiment, as a process when the calling number does not match all of the calling numbers in the incoming call control memory section 38, the incoming call is rejected according to the "call setting" information, or the call is sent to a predetermined specific key telephone. You can also receive calls.

Next, the second invention will be explained with reference to the drawings.

FIG. 3 is a block diagram showing an embodiment of the second invention.

In FIG. 3, the main device of this embodiment of the second invention is the first
The difference from the embodiment of the first invention shown in the figure is that key telephones 11 to 14 are accommodated, and a memory section 37a includes an incoming call restriction memory section 39.

FIG. 4 is a diagram showing a memory map of the incoming call restriction memory section in the embodiment shown in FIG. 3.

In FIG. 4, the incoming call restriction memory section 39 is composed of registration areas 71, 72, 73, and 74 corresponding to each telephone.

FIG. 5 is a flowchart showing an example of a process for controlling incoming calls by the main control unit of the embodiment shown in FIG.

Next, the operation of this embodiment will be explained using FIGS. 3, 4, and 5.

First, in order to restrict incoming calls for each key telephone,
Register the phone number of the person you want to allow to receive calls from each key phone. The registration operation will be explained using the button telephone 11 as an example.

When a special button on the button telephone 11 is pressed, the main control section 34 changes to a state in which incoming call restriction is registered. Next, when the telephone number of the other party to whom incoming calls are permitted is input using the dial button of the button telephone 11 and the special button is pressed again, the main control unit 34 converts the telephone number entered through the dial buttons into the number to which incoming calls are permitted. Registration of button telephone 11 in incoming call restriction memory section 39 in memory section 7a as =
9 = 0 Write processing to area 71 is performed.

When registering the telephone numbers of a plurality of parties from one key telephone, this can be achieved by repeatedly performing the above-mentioned operations.

Next, the processing of the main control unit 34 when the call setup j information is notified to the ISDN line will be explained.

Now, when "call setup" information is notified to the ISDN line,
This information is notified to the main control unit 34 via the 877-point interface 33 of the 15DN. The main control unit 34 starts the process shown in the flowchart of FIG.

First, the "call setup" information sent from the I'SDN line is analyzed (process 41), and the presence or absence of the calling number is confirmed (
Processing 42). If there is no calling number, the caller will not be able to receive the call because it is unknown who the caller is, so the main control unit 34 will notify the ISDN line through the ISDN 877 point interface 33 that the call cannot be received (
Processing 51).

If there is a calling number, the calling number is extracted from the "call setting" (process 43).

Next is a process of reading out the telephone number stored in the incoming call restriction memory unit 39.

First, it is checked whether processing of all areas 71 to 74 corresponding to each key telephone in the incoming call restriction memory unit 39 has been completed (process 44). If it is confirmed that the process has not been completed, it is then confirmed whether reading of the telephone number in the registration area that is currently being executed has been completed (process 45). here,
After confirming that the serial number has not been completed, reading processing of the telephone number stored in the first registration area 71 is started.

First, one of the telephone numbers stored in the registration area 71 is read out (process 46), the read telephone number is compared with the calling number (process 47), and if the two values do not match, process 45 is executed again. If they match, the key telephone 11 is notified of the incoming call via the key telephone interface 31 (process 48), and an incoming call flag is set (process 49).
), the process returns to step 44.

In addition, in process 45, processes 45 to 47 are repeated until the end of reading is confirmed, and at the time it is confirmed, process 44 is executed.
Return to

Next, in process 44, all button telephones 11 to 1
When it is confirmed that the process for No. 4 has ended, the incoming call flag is checked (process 50). If there is an incoming call flag, it means that the call has been received, and the process ends. If there is no incoming call flag, there is no button phone that allows incoming calls, so call 877 of l5DN.
Notify the point interface 33 that the call cannot be received (processing 51
), the process ends.

With the above process, when an incoming call is received on the l5DN line,
According to the calling number sent from the SDN line, it is possible to restrict incoming calls that are not required by the called party.
