Abstract

PURPOSE:To previously prevent the generation of misconnection due to the artificial misinput of a dial number by comparing the number of digits of an inputted dial number with that of a stored local dial number when the inputted dial number is a local dial number, and when the number of digits is over the reference one, generating an alarm and suggesting the reinput of the dial number. CONSTITUTION:When a dial number inputted from a dial input means 1 in a device connected to an extension is a local dial number, a dial number digit comparing means 4 compares the number of digits of the inputted dial number with the number of digits previously stored in a dial digit number storing means 2, and when both the numbers coincide with each other, calling is executed. At the time of discrepancy of both the numbers, an error alarm is generated and the reinput of the dial number is suggested. Consequently, the generation of misconnection due to the artifical misinput of a dial number can be previously prevented.

Description

[Detailed Description of the Invention] [Summary] Regarding a dial error prevention method for preventing dial errors from an extension to a central office line, a comparison is made with the number of digits stored in advance when the input dial number is a local dial number. Local dial digit number memory that stores the number of digits of local dial numbers in advance, with the aim of preventing incorrect connections due to human input errors in dialing numbers, by issuing a warning when the number of digits is exceeded. means, the number of digits of the local dial number input when the dial number input from the dial input means is a local dial (for example, one rOJ at the beginning), and the number of digits of the local dial number stored in the local dial digit number storage means. dial digit number comparison means for comparing the number of dial digits with the number of local dial digits, when the dial number input from the manual dialing means of a device connected to the extension (e.g. a pick-up axis device) is a local dial number. Then, the dial digit number comparison means compares the number of digits of the input local dial number with the number of digits stored in advance in the dial digit number storage means, and when they match, issues a local dial number. If there is a discrepancy, the system is configured to issue an error warning and prompt for re-manpower.

[Industrial application field]

The present invention relates to a dial error prevention system for preventing dial errors from an extension line to a central office line.

[Conventional technology]

In recent years, in order to reduce communication costs, companies are increasingly using a communication network using internal lines for internal communication and a communication network using central office lines for external communication. NTT's dial-in service is a service that fulfills these needs. Communication equipment connected to dial-in service (
For example, when a facsimile machine (W) makes a call to a central office line, it is usually necessary to enter rOJ at the beginning of the dial to enter the central office line. Therefore, when making a long distance dial call from Tokyo to Kawasaki, for example, after entering "0" at the beginning of the dial, continue dialing the destination's area code, for example RO 44J.
You need to enter the Tochichi area code r754-5678. If you write this continuously, you will enter rO-044-754-5678J.

[Problem to be solved by the invention]

However, human errors such as forgetting to enter the first "0" during dial input often occur. In this case, if you forget the leading "0", r044-754-5
678J will be dialed. On the other hand, the exchange interprets the "0" of ro 44J to mean a central office call, and then dials 447-545678J as a subscriber number within the Tokyo area. Because the call is ignored, there is a problem where the wrong number is dialed to "r447-5456" in the Tokyo area. Nowadays, facsimile machines are widely used in most companies, and there is a problem in that human errors such as those described above can cause facsimile messages to be mistakenly sent to other companies.

The present invention issues a warning when the input dial number exceeds the number of digits stored in advance when it is a local dial number, and connects incorrectly due to human error in the dial number. The purpose is to prevent this from happening.

[Means to solve the problem]

FIG. 1 shows a basic configuration diagram of the present invention.

In FIG. 1, dial input means 1 is for inputting dial numbers manually.

The local dial digit number storage means 2 stores the number of digits of a local dial number in advance.

The dial digit number comparison means 4 determines whether the dial number input from the dial input means 1 is a local dial number (for example, if the number starts with "
The number of digits of the dial number input when the number 0 is one is compared with the number of digits of the local dial number stored in the local dial digit number storage means 2.

[Effect]

As shown in FIG. 1, the present invention provides a system in which a dial number input from the dial input means 1 of a device (for example, a facsimile machine W) connected to an extension is a local dial number (for example, "0" at the beginning of the dial number). is 1), the dial digit number comparison means 4 compares the number of digits of the input dial number with the number of digits stored in advance in the dial digit number storage means 2, and when they match, the signal is emitted. If there is a discrepancy, an error warning is issued to prompt re-manpower.

Therefore, when dialing a central office line from a facsimile device connected to an extension, if the input dial number is a local dial number, the number of digits of this number and the number of digits of the memorized local dial number are calculated. By making a comparison and issuing a warning when the number of digits is exceeded, it is possible to prevent erroneous connections due to human input errors in dialing numbers.

〔Example〕

Next, the configuration and operation of the embodiment of the present invention will be explained in detail using FIGS. 1 to 3.

In FIG. 1, dial input means 1 is for inputting a dial provided on a facsimile machine or the like connected to an extension line.

The local dial digit number storage means 2 stores the number of digits of a local dial number in advance. For example r754-567
When it is 8J, it is stored as 7 digits.

The local dial recognition means 3 recognizes (discriminates) whether the dial number input from the dial input means 1 is a local dial number or not. If there is one "0" at the beginning of the dial number input from means 1, the number following this is determined to be a local dial number, and on the other hand, if there are two "0"s at the beginning of the input number Sometimes a leading “0”
The number following is determined to be a long distance dial number.

Here, the first "0" is used to make the extension exchange determine that when a call is made from the extension to the central office line.

When the dial number input from the dial input means 1 is recognized by the local dial recognition means 3 as a local dial number (when there is one "0" at the beginning), the dial digit number comparison means 4 compares the number of digits at the beginning of the dial number. The number of digits of the dialed number following "0" is compared with the number of digits of the local dialed number taken from the local dialed digit number storage means 2, and when they match, it is determined that it is a correct local dialed number. On the other hand, if the number does not match, it is determined that the local dial number is incorrect, and the warning generating means 5 is notified and a buzzer is sounded. In response to this, the operator performs re-input.

Next, the operation of the configuration shown in FIG. 1 will be explained in detail using the flowchart shown in FIG.

■: Dial input. In this case, an operator inputs a dial number from the dial input means 1 shown in FIG.

0: Determine whether or not the location is within the city. This determines whether there is one "0.'" at the beginning of the dial number input in step (■) (for calling from an extension to the central office line).There are two "0"s at the beginning of the dial number. number (the first number is for calling from an extension to a central office line, and the second number is for an area code), it is a long-distance dial number. this is,
FIG. 1 Local dial recognition means 3 determines whether the input dial number is a local dial number or not. YES
In the case of (local dial number), proceed to ■. N
In the case of O (in the case of a long-distance dial number), press ■ to make a call.

@:0 Since the local dial number has been determined by YES, it is determined whether the number of digits matches the number of digits of the local dial number. This is determined by the number of dial digits comparing means 4 in FIG. It compares it with the number of digits extracted and determines whether it is -i. If YES, the number of digits is equal to the number of digits in the local dial number, so it is determined that the local dial number is correct, and a call is made to this local dial number in (■). On the other hand, N
In the case of o, the number of digits is different from the local dial number, so
Press ■ to display an error or sound a buzzer to warn the operator and prompt him to re-enter, and press [Phase] for the operator to re-enter. Then repeat the steps after @.

As described above, when an operator inputs a dial number from dial input means 1 such as a facsimile device connected to an extension, the number of digits of the local dial number stored in advance at the time of local dial number By comparing the numbers and calling when they match, and issuing a warning and prompting re-input when they do not match, it is possible to prevent misdialing of the dial number from the extension line to the central office line.

FIG. 3 shows a system configuration diagram of the present invention. The illustrated system is installed in a device (for example, a facsimile machine, a telephone, etc.) connected to an extension line, and an O call is made from the extension line to the central office line. This is used to connect to the other party's device and make a call by dialing a local dial number or long-distance dial number.

In FIG. 3, a dial input section 11 corresponds to the dial input means 1 in FIG. 1, and is used to input a dial number.

The local dial digit number storage section 21 corresponds to the local dial digit number storage means 2 in FIG. 1, and, as described above, stores the number of digits of a local dial number.

The local dial recognition section 31 corresponds to the local dial recognition means 3 in FIG. 1, and determines whether or not the dial number input from the dial input section II is a local dial number. The determination is made based on whether or not there is one "0".

The dial digit number comparison section 41 corresponds to the dial digit number comparison means 4 in FIG. The number of digits of the dialed number is compared with the number of digits of the local dialed number retrieved from the local dialed digit number storage unit 21, and if they match, it is determined to be a local dialed number, and if they do not match, it is determined to be a local dialed number. This is determined to be a number.

When the number of digits of the pre-memorized local dial number and the number of digits of the input local dial number do not match, the display unit 5 displays a warning to the effect of a dialing error, and prompts the user to re-enter the number. It prompts the user and displays the dialed number that has been entered.

The alarm sound generation unit 52 generates an alarm sound to notify the operator of a dial error when the number of digits of a pre-stored local dial number and the number of digits of the input local dial number do not match. It is something to do.

The dialing unit 61 is for dialing.

The communication control unit 71 connects to the other party via an extension line or a central office line and performs various communications.

The reading unit 81 reads an image of a document provided in a facsimile device or the like. The read image is compressed and transmitted to the other party by the communication control unit 71.

The recording unit 91 records data transmitted from the other party via a central office line or extension line on paper or the like.

The device control section 100 controls the entire device.

Next, the operation will be explained according to the flow from ■ to ■.

■: Input the dial number from the dial input section 11.

The input dial number is transmitted to the dial calling unit 61 and the local dial recognition unit 31.

The local dial recognition unit 31 that receives the dial number at ■: ■ recognizes (determines) whether or not it is a local dial number. It is recognized as a local dial number, and when there are two, it is recognized as a long distance dial number. When the number is recognized as a local dial number, the number of dialed digits comparison section 41 is notified of this fact. On the other hand, when it is recognized as a long-distance dial number, it is notified to the dial calling unit 61 and a call is made.

(2) Read the number of digits of the pre-stored local dial number from the double dial digit number comparison unit 21 and notify it to the dial digit number comparison unit 41;

■: The dial digit number comparison unit 41 compares the number of digits of the input local dial number with the number of digits notified from the local dial digit number storage unit 21, and if they match, the number of digits in the input local dial number is correct. It is determined that the number is a dial number, and the dial calling unit 61 is notified and a call is made. On the other hand, if it does not match -, it is determined that the local dial number is a mistake, and the display section 5I and alarm generation section 5
2, display that the dialed number is incorrect, or generate an alarm sound, and issue a warning to the operator that the dialed number is incorrect and prompt him to re-enter the number. The operator re-enters the dialed number.

〔Effect of the invention〕

As explained above, according to the present invention, when dialing a central office line from a facsimile device connected to an extension, when the input dial number is a local dial number, the number of digits is stored in advance. The system compares the number of digits of the local dial number entered and issues a warning when the number of digits is exceeded, prompting the user to re-enter the number, thereby preventing erroneous connections due to human error in entering the dial number. It can be prevented.

This makes it possible to avoid leakage of secrets due to incorrect connections when transmitting facsimile messages.
