The above-confirmed call connection is restored when either subscriber circuit detects the on-footer (step 517).
.

[Problem that the invention seeks to solve]

In the conventional private branch exchange system, the fact that M-registration has been carried out is notified by the lighting of the M-lamp on the telephone, but since it is not known who is the source of the M-registration, it is difficult to confirm at the gate. - There is a problem in that the question registrant must be called and confirmed using an execution special number, and the number of registrants is limited to one person.

Further, when canceling all MW registrations, there is a problem that the registration source is called as described above and the registration is not canceled until the registrant responds.

[Means for solving problems]

FIG. 1 is a block diagram showing the principle of the invention.

In the figure, 11-1 and 11-2 are telephones, 5 is a network, 9 is a central controller that controls the entire private branch exchange system, and 10 is a memory device that stores programs and data used by the central controller 9.

Things related to the present invention will be described below.

11A is a display that displays a series of registered destination numbers, and 11B is a central controller 9 that sends a control signal to display on the display 11A.
1 function button 101 is a registration source number table for recording multiple registration destination numbers for one registration destination telephone number, 91
92 is a display control means for detecting a control signal from the MW function button 11B and displaying a series of registration destination numbers corresponding to the registration destination telephone numbers in the registration source number table 101 on the display 11A; It is activated by the detection of a dial number corresponding to the rank, deletes the registration number in the registration source number table 101 specified by the dial number, moves the registration destination number of the next rank to the blank registration source number column, This is a registration source number processing unit that sequentially moves the recording positions of the registration destination numbers of lower rankings and re-edits the accommodation positions of the registration destination numbers.

[Effect]

When the MW registrant presses the arm function button 11B, a control signal for displaying the registration destination number is sent from the telephone 11-1 to the central controller 9.

The display control means 91 detects the control signal and displays the memory device 1.
A series of registration source number numbers related to the telephone number of the first registrant (registration destination telephone number) recorded in the registration source number table 101 of 0 is displayed on the display 11A of the telephone 11-1.

The M-registrant looks at the displayed registration numbers, and if there is a registration number that he/she wishes to cancel the registration, dial the dial number corresponding to the order of the registration number that he/she wishes to cancel in the series of registration numbers, and dial the number on-hook. By dialing as is, the registration source number processing means 92 is activated, and the registration destination number in the order specified by the dialed number is deleted.

Move the registration destination number of the next rank to the registration source number field that is now blank, move the recording position of the registration destination number in the lower order forward, move the recording position of the registration destination number, and re-edit the storage location of the registration destination number. I do.

After the re-editing, the re-edited series of registration destination numbers is displayed again on the display 118 by the display control means 91, and the M-registration cancellation is confirmed.

In this way, when the 1 function button 11B is pressed, a series of registration destination numbers are displayed on the display 118, so it is immediately clear who has registered all the MWs, and the registration can be canceled without calling the registration source. This is achieved by sending a dial number corresponding to the desired registration source and number's ranking on the display.

〔Example〕

The present invention will be specifically explained below with reference to illustrated examples.

Fig. 2 is a block diagram of a private branch exchange system according to an embodiment of the present invention, Fig. 3 is an explanatory diagram of display contents of a display, Fig. 4 is an explanatory diagram of one registration processing procedure of the present invention, and Fig. 5 is an explanatory diagram of the present invention. The same reference numerals indicate the same objects throughout the drawings.

In FIG. 2, 1 function button detection section 931 display control section 94
corresponds to the display control means 91 in FIG.
1 editing section 96 corresponds to the registration destination number processing means 92 in FIG.

All MW registration will be explained with reference to FIGS. 2 and 4.

Now, assume that the subscriber of telephone 11-H (phone number 301) is absent and the subscriber side of telephone 11-2 (phone number 302) is to be registered.

When telephone 11-2 goes off-hook, subscriber circuit 4-2
detects an off-footer (step 550 in FIG. 4) and starts the central controller 9.

The central controller 9 connects the subscriber circuit 4-2 to the dial tone sending circuit 6 via the network 5 in a conventional manner, and causes the dial tone to be sent out (step 551).

When the subscriber dials an M-registered special number, for example, special number 14, the dial detection section 11 of the central control unit 9 detects the special number (step 552), activates the registration section 12, and subsequently dials the received registration number 301. (step 553)
).

The registration unit 12 captures the registration destination number table 101 according to the present invention in the memory device IO, and records the telephone number that requested all MW registration in the blank field of the registration destination number column for the registration destination telephone number 301. In the example in Figure 2, the registration number 100.1 has already been registered.
Since 01.203 is recorded, the registration number 302 is recorded in the fourth registration number column (step 554).
.

When the above registration is completed, the lamp control unit 13 operates, sends a control signal to the telephone 11-1, and turns on the h lamp 3B (
Step 555).

Thereafter, the completion sound sending circuit 7 and the subscriber circuit 11-2 are connected using a general control method, and a completion sound is sent out (step 3).
56). When the on-footer is detected in the subscriber circuit 4-2, the central control device 9 restores the connection between the completion tone sending circuit 7 and the subscriber circuit 11-2 (step 557).

The registration source confirmation and 11W registration cancellation will be explained with reference to FIGS. 2, 3, and 5.

The subscriber of telephone 1stll-1 went home and turned to MW lamp 3B.
Knowing that h has been registered because it is lit, press 1 function button 11B with the phone still in the on-footer state.
When the button is pressed, the MW function button detection unit 93 detects this (step 560 in FIG. 5) and operates the display control unit 94.

The display control unit 94 registers the registration number table 101 of the memory device 10.
to determine whether there is a record in the registration number field corresponding to the telephone number 301 (step 561), and if there is a record, a series of registration numbers (100, 101) in the registration number field are detected.
, 203, 302), and displays the registration number 100.101, 203, 302 on the display 11A of the telephone 11-1 as shown in FIG. 3 (step 563).

This display confirms the MW registration source. In the above step S61, if there is no registration number, the process ends immediately.

When the subscriber looks at the registration number displayed on the display 11A,
M-registration can be canceled for registered numbers that do not require calls.

That is, the display 11 of the registration number whose registration is to be canceled.
Dial the dial number corresponding to the display order in A using the dial key 3A. For example, if you want to cancel the second registration source number 101 in FIG. 3, dial the dial number 2.

The registration cancellation unit 95 receives the dial number (dial number 2 in the above example) corresponding to the display order of the registration number for which all MW registration is to be canceled (step 565), and registers number table 1.
The registration destination number 101 corresponding to the received dial number 2 in the registration destination number field of 01 is deleted and the wi section 96 is operated (step 366).

In the registered number column of the telephone number 301, the editorial department 96 writes:
The registration destination number 203 is incremented in the column of the deleted registration destination number 101, the registration destination number 302 is also incremented, and the accommodation position of the registration destination number is re-edited (step 567).

If the display control unit 94 determines that the registration number corresponding to the telephone number 301 remains after the re-editing is completed (step 568), the process returns to step S63 and the series of registration numbers 100, 203, 302 is returned to step S63. It is displayed on the display 11A to confirm that the registration number 101 has been canceled.

Furthermore, (1) If you wish to cancel the registration, repeat steps S65 and subsequent steps, but if you do not wish to cancel the registration, press the MW function button 11B again. The MW function button detection unit 93 detects this and terminates the MW registration cancellation (step 570).

If it is determined that all registration numbers have been canceled (step 568), the lamp control unit 13 turns off the MW lamp 3B of the telephone 11-1, and this procedure ends (step 569). .

〔Effect of the invention〕

As described in detail above (in the present invention, by displaying the registration source number on the display of the telephone, it is possible to know from whom the registration was made before the call is made).

Furthermore, for I registrants who do not require calls, all MW registrations can be arbitrarily canceled while remaining in the on-footer state.
