Description

Description: TECHNICAL FIELD The present invention relates to a telephone which facilitates a recovery operation when a dial operation is mistaken.

[Conventional technology]

FIG. 4 is a timing chart showing a conventional method for recovering from a dial operation error in a telephone. Each operation will be described below.

As shown in the figure, first go off-hook and then, for example, 03-50
Suppose that you want to dial the dial number 9-1234, but accidentally dial the dial number 03-509-1235.

In such a case, conventionally, it was necessary to once go on-hook, disconnect and restore the call, and then go off-hook again to perform a correct dial operation.

[Problems to be solved by the invention]

However, the telephone having the above-mentioned configuration has a drawback in that the dial operation is redone from the beginning, which is troublesome and the operability is poor. In addition, the telecommunications business has been liberalized recently, and in the future, multiple networks will be constructed and exist by different vendors, so the selection of these multiple networks, or
When the network is connected to communicate, a larger number of dial operations are required, so that there is a problem that the emotional pain of re-doing the operation at the time of a mis-dial is further increased.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a telephone capable of correcting an erroneous dial operation by a simple operation without redoing the dial operation from the beginning. To do.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a storage means for pressing and pushing a push button dial after inputting a telephone call, inputting and storing a dial number to be transmitted, and a display means for displaying the dial number. Cancellation means for sequentially canceling the correction of the dial number erroneously input to the telephone by one digit from the last digit of the input dial number, and the dial number before the canceled digit is the storage means. And the storage control means for holding the number, the line is temporarily disconnected when the canceling means is operated, and after the operation is completed, the line network is restored, the call is automatically recalled, and the dial number held in the storage means is automatically set. The call control means is provided so that the canceled digit and the subsequent dial number can be input after the transmission.

[Action]

Since the present invention is configured as described above, even if an operation for entering a dial number is incorrect, a corrective button for immediately canceling the incorrectly entered dial number is pressed, and the entered number is removed to correct the operation. It is possible to correct a dial operation error and make a call without entering a number and then dialing from the beginning.

〔Example〕

FIG. 1 is a block diagram of an embodiment of the present invention, which is an embodiment in the case of a digital telephone.

In FIG. 1, reference numeral 1 is a DSU (digital line terminating device).
Terminal for connecting to, 2 is a power separation-balanced / unbalanced conversion circuit, 3 is a power supply circuit, 4 is a network interface circuit, 5
Is a storage means for storing the dial number being sent, and 6 is a CPU
A signal control circuit configured to perform various input / output control / call processing, 6a reads out the dial number stored in the storage means 5 when a predetermined input signal (cancel input) is received during dial number transmission, Dial storage control means that removes only the end number and stores it again, 6b automatically disconnects the call and restores when a predetermined input signal is received,
Call control means for automatically calling again and then automatically sending the dial number stored in the storage means 5 to the network, 7 requests the signal control circuit 6 to cancel the immediately preceding input dial during the outgoing dialing. A button for correction, 8 is a hook switch, 9 is an indicator, 10 is an indicator drive circuit for driving the indicator 9, 11 is a push button dial, 12 is a sounder, 13
Is a calling circuit, 14 is a receiver, 15 is a transmitter, 16 is a calling circuit,
17 is a codec.

Next, the operation will be described.

For example, in order to talk with the other party having the dial number 03-509-1234, when the dial is pushed with the push button dial 11 after the off-hook, the number is displayed on the display unit 9.
If you accidentally operate the dial number 03-509-1235, that number will be displayed on the display, so press the button 7 for dial operation correction (dial cancellation) immediately. The signal control circuit 6
Sequentially activates the dial storage control means 6a and then the call control means 6b. The dial storage control means 6a reads the dial number "035091235" stored in the storage means 5 when the push button dial 11 is operated, removes only the last digit, and stores it again. At this time, at the same time, the signal control circuit 6 performs display control, and the display 9 is displayed on the display 9 via the display drive circuit 10.
"509123" is displayed to notify the user that the end of the display has been canceled.

Next, the call control means 6b automatically disconnects the call once, restores it, and then automatically calls again to automatically send the dial number of the storage means 5 to the network. After that, by pressing the correct number "4" by the push button dial switch 11, the dial number "035091234" is transmitted to the network. FIG. 2 is a timing chart showing a procedure for recovering from a dial operation error in this embodiment.

In the above embodiment, the case of correcting the last digit of the dial number has been described, but in the case of correcting other than the last digit, for example, 03-509-1234 where the dial number should be operated, 03-509- When the dial number 1244 is operated, the dial correction button 7 may be pressed twice to update the stored content twice. Further, if the cursor key is also used, it is possible to push the dial correction button 7 after moving the cursor to any digit.

Further, in the above embodiment, as is clear from FIG. 2, after the call is disconnected and restored, the call is immediately issued and the storage means 5 is connected.
The dial number stored in is sent to the network, and then the correct number is sent to the network. However, as shown in the timing chart in FIG. 3, the correct number is set after disconnecting and restoring the call. In addition to the dial number entered and stored in the storage means 5, the corrected dial number stored in the storage means 5 may be sent to the network at the same time as the call is made.

On-hook after the connection of the other party, the call is disconnected and restored, while the storage means 5 retains the input dial at that time, but the display of the display 9 is canceled by the signal control circuit 6. . Then, in the next dial number transmission, at the same time when the first dial is input, the previous memory of the storage means 5 is canceled and a new dial number is stored in the first position, and at the same time the display 9 displays the first number. . Thereafter, the same operation is repeated, and the dial number is stored in the storage means 5 and sent to the network.

Further, in the above embodiment, the case of the digital telephone has been described, but it goes without saying that the invention can be applied to an analog telephone.

〔The invention's effect〕

As described in detail above, according to the present invention, when a user mistakenly inputs a dial number during a dial operation, the correction button is pressed to disconnect the call and terminate the input dial number. It is possible to cancel sequentially from the digits, and the numbers of the digits that have not been canceled are stored in the storage means, and once the disconnected network is restored, another call is automatically made and stored in the storage means. Since the dialed number is sent to the network, you can enter the number after the previously canceled digit, which has the effect of not on-hooking the dial operation and not having to repeat the dial operation from the beginning. is there.
