Abstract

PURPOSE:To correct a dial number back to an erroneous dial number by depressing a mis-operation information sending means in the event of dialing an erroneous number so as to erase the final number of a dial number storage area thereby avoiding the entry of dial number from being given up on its halfway. CONSTITUTION:A caller making notice of mis-dialing depresses a mis-operation information transmission button of a multi-function telephone set 1 subject to dialing. The mis-operation information from the telephone set 1 is sent to an exchange and given to a central controller 7 via a subscriber circuit 3 and the controller 7, based on said information, applies correction processing to a dial number stored in the corresponding dial number storage area 11. As a result, the content of the dial number storage area is restored in the state that dial numbers '2', '4' are stored respectively in dial number storage areas 111, 112. Thus, the input of the dial number is not given up on its halfway and the dial number is corrected back to the erroneous dial number.

Conventionally, in an automatic exchange equipped with a multi-function telephone, when the caller performs an off-footer, the central control unit performs call processing such as selecting a register, the caller hears a dial tone, and then the caller makes a call. The register receives and stores the dialed digits as the caller sequentially inputs the digits of the called party's number through the keypad of the multifunction telephone.

[Problem that the invention seeks to solve]

The automatic exchange system that accommodates the conventional multi-function telephone mentioned above does not have a function to correct the dialed digits during the dialing operation, so if the wrong dialed digits are sent due to the caller's erroneous operation of the dial keypad, The caller is-
There is a drawback that by performing the H on-hook operation, the call processing must be abandoned midway and the off-hook operation must be repeated to perform the call processing.

[Means for solving problems]

In the automatic exchange with dialed digit correction function of the present invention, the multifunction telephone has an operation error information transmission means for transmitting information indicating that an incorrect number has been dialed according to instructions from a caller.

A dialed number storage area, a received dialed number digit count area in which the number of digits of the dialed number stored in the dialed number storage area, and a number of received dialed number digits count area in which the number of digits of the dialed number stored in the dialed number storage area are stored.
Each digit of the dialed number is sequentially stored in the dialed number storage area, and the number of digits of the dialed number stored in the received dialed number digit count area is increased to indicate that an incorrect number has been dialed. When the information is transmitted from the erroneous operation information transmission means,
The last dialed digit stored in the dialed digit storage area is deleted from the dialed digit storage area, the number of digits stored in the received dialed digit digit count area is decreased, and then the corrected digit is dialed. when the corrected dialed number is stored in the dialed number storage area where the dialed number due to the erroneous operation was deleted, and the control means automatically increases the number of digits stored in the received dialed number digit number (run) area. The exchange has.

[Effect]

Therefore, if you enter an incorrect number from a multi-function telephone, you can go back to the incorrect number and correct the number without abandoning the input operation, so you can start from the first number again. The caller can be freed from the trouble of having to input duplicate operations.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an automatic switching system with a dial digit correction function according to the present invention, and FIG. It is a diagram showing an area configuration.

The multifunction telephone 1 and the extension telephone 2 each have a subscriber circuit 3.
, 4 to the switching network 6;
A resistor 5 is connected to the switching network 6. The central control unit 7 controls the subscriber circuit 3.4, the switching network 6, and the register 5 using station data stored in the storage device 8, programs necessary for switching processing, and the like. The storage device 8 is provided with a dialed digit storage area 11 and a received dialed digit digit count area 12. Second. Third. The 4th dial number is
The central controller 7 sequentially stores the dial digits in the dial digit storage areas II, , 112, 113, 114, and the number of digits of the dial digit stored in the dial digit storage area 11 is counted by the central controller 7 as the number of received dial digits. It is stored in area 12. On the other hand, the multifunction telephone 1 is provided with an erroneous operation information transmission button (not shown), and by pressing this button when the dialed number is erroneously operated, the erroneous operation information indicating that the erroneous number was dialed is transmitted to the multifunction telephone. It is transmitted from l to the exchange.

Next, the operation of this embodiment will be explained.

Now, a certain subscriber calls the extension phone number "2" from the multi-function telephone l.
Let's assume that you are trying to make an extension call to a subscriber of extension telephone 2 assigned "468", and you mistakenly dial "247" when you should have dialed "2468".At this point, the dialed digits are stored. Area 11+, 1
The contents of 12 and 113 are in the order in which the dialed numbers are received.
"2", "4", and "7", and the contents of the reception dial digit count area 12 indicate "3". Therefore, when the caller who notices the dialing error presses the erroneous operation information transmission button on the multifunction telephone 1 that made the call, the erroneous operation information is transmitted from the multifunction telephone 1 to the exchange and transmitted via the subscriber circuit 3. This information is input to the central control device 7, and the central control device 7 performs a correction process on the dialed number stored in the corresponding dialed number storage area 11 based on this information. That is, the central control device 7 stores the dial number "7" dialed just before in the storage area l.
13, and the content of the received dial number digit count area 12 is set to "2". As a result, the contents of the dialed number storage area are as follows: dialed number storage area 11. , 112 respectively store the dialed digits "2" and "ji".Then, the caller returns to the state where the dial numbers "2" and "ji" are stored respectively.
By operating the dial, the dial numbers ``6'' and ``8'' are stored in the dial number storage areas 113 and 114, respectively.
'' is stored, the content of the received dial number digit count area 12 becomes ``4'', and the central control unit 7 performs a calling process to the extension telephone 2 with the extension number ``2468''.

Note that by pressing the erroneous operation information transmission button multiple times on the multifunction telephone 1, the caller can go back and correct the dialed digits that have been input as many times as the button has been pressed.

〔Effect of the invention〕

As explained above, the present invention provides a dialed digit storage area and a received dialed digit digit count area in the exchange, and also provides a multi-function telephone with an erroneous operation information transmission means, so that when an erroneous digit is dialed, the erroneous operation information transmission means is pressed. By deleting the last digit in the dialed digit storage area, if you enter an incorrect dialed digit from a multifunction phone, you can trace back to the incorrect dialed digit without abandoning the dialed digit entry operation. This has the effect of freeing the caller from the trouble of having to enter the initial dialed digits again due to repeated operations.
