Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone number input correction system in an exchange. As the number of subscribers accommodated in the telephone network increases, the number of digits of the telephone number given to each subscriber also increases, and when the calling subscriber calls the called subscriber, a multi-digit telephone is used. The need to choose a number increases the chance of choosing the wrong number along the way.

[0002]

2. Description of the Related Art Generally, a telephone set used by a subscriber sends a selected number to a one-digit addressed exchange when the subscriber makes a call and selects the telephone number of the called subscriber by one digit.
Receives and stores the digits sent from the calling subscriber addressed to one digit,
The connection destination is decided after receiving all the numbers.

Incidentally, recent telephones are equipped with a function of selecting a special code (for example, (#) or (*) etc.) in addition to the numbers (0) to (9) such as a push button dial. However, in the present invention, the numbers (0) to (9) selectable by the calling subscriber and the special code are combined,
Collectively referred to as "numbers and the like".

In a conventional exchange of this type, while the calling subscriber is selecting the telephone number of the called subscriber,
In case of noticing an incorrect selection of digits, it is necessary to release the call once and then make a call again to reselect the telephone number of the called subscriber from the first digit.

[0005]

As is apparent from the above description, in the conventional exchange, the calling subscriber may select an incorrect number while selecting the telephone number of the called subscriber. If you notice it, you need to release the call once, make a call again, and reselect the telephone number of the called subscriber from the first digit, and the correct digit selected before the wrong digit is invalid. Therefore, there is a problem that the calling subscriber spends unnecessary labor and time.

An object of the present invention is to make it possible to reduce the labor and time required for correcting a telephone number of a called subscriber when the calling subscriber mistakenly selects the telephone number of the called subscriber.

FIG. 1 is a diagram showing the principle of the present invention. In FIG. 1, reference numeral 100 denotes an exchange which is a target of the present invention, 101 denotes a numerical analysis means included in the exchange (100), and 200 denotes a subscriber accommodated in the exchange (100).

Reference numeral 102 denotes an exchange (100) according to the present invention.
It is a number correction means provided in.

[0009]

The numerical analysis means (101) is used by the calling subscriber (20
Receive the number sent from 0) to 1 digit and analyze the connection destination.

When the numeral analyzing means (101) detects that the numeral etc. specified for correcting the numeral etc. is received, the numeral correcting means (102) invalidates the numeral etc. received immediately before, and thereafter receives it. The received number or the like is received as the same digit or the like as the invalid number or the like.

The number correcting means (102), when a plurality of numbers or the like for correcting the numbers etc. are continuously received, selects from the numbers or the like received immediately before the number of times of receiving the numbers or the like for correcting the numbers or the like. It is considered to invalidate the digits after the trace.

Further, the numeral correcting means (102) uses, as a numeral for correcting the above-mentioned numeral, a numeral not used for a telephone number selected by the calling subscriber (200) for designating a connection destination, For example, it is considered to define a selection code or the like (#) on the push button dial.

Therefore, if the calling subscriber notices that he / she has selected an incorrect number or the like while selecting the telephone number of the called party, he / she selects the above-mentioned number or other corrective number. It is possible to invalidate the selected digits, etc. retroactively by the number of digits, and to reselect after the incorrect digit, so there is no need to reselect to the correct digit, and the telephone number of the calling subscriber. The selection work will be greatly streamlined, and the convenience of the exchange will be greatly improved.
