Abstract

PURPOSE:To regulate the transmission of a line wire by comparing a registered pass code with an inputted pass code and generating a warning tone from a telephone set under the input of the pass code when the input is missed more than the fixed number of times. CONSTITUTION:A main unit 1 is equipped with a main control part 3, key telephone set unit 4, storing part 5 and warning tone sending circuit 6. The storing part 5 is provided with a pass code storing part 51 to enable the pass code to be used when the transmission of the line wire is regulated for each system, a miss time storing part 52 to store the number of times to miss the input of the pass code for each telephone set, an input code storing part 53 to temporarily store contents inputted by dialing at the time of line wire transmission, a miss designation storing part 54 to store the number of times to miss designation, and a digit number storing part 55 to store the number of digits in the pass code. The registered pass code is compared with the inputted pass code and when the input is missed more than the prescribed number of times, the warning tone is generated from the telephone set under the input of the pass code. Thus, the transmission of the line wire can be regulated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone device, and particularly to an improvement of a main device having a function of restricting outgoing calls.

[Conventional technology]

Conventionally, in key telephone devices that control multiple key telephones from the main device, a passcode is registered for each key telephone and this passcode is entered in order to restrict outgoing calls from each key telephone. The system is designed so that you cannot make outside calls unless you do so.

[Problem to be solved by the invention]

The above-mentioned conventional button telephone devices are not designed to generate a warning sound when the registered passcode and the input passcode are different, so it is possible to do so without being noticed by other users. , the passcode can be re-entered many times until it matches the registered passcode.Therefore, there is a problem in that if the passcode is re-entered many times, it is not possible to restrict outgoing calls.

It is an object of the present invention to provide a key telephone device that eliminates the problem of being unable to restrict outgoing calls due to repeated passcode input.

[Means to solve the problem]

The button telephone device of the present invention includes a plurality of button telephones each equipped with a speaker and a main device accommodating these key telephones. Passcode entered. A storage unit that stores the number of passcode input errors, etc., a control unit that compares the passcode input from each button telephone with the stored passcode and detects the number of input errors, and a control unit that detects the number of input errors, and the number of passcode input errors. and a warning sound sending circuit which generates a warning sound from the speaker of the button telephone when the value is above a certain level.

[Effect]

In this configuration, the registered passcode is compared with the input passcode, and if the input is incorrect more than a certain number of times,
When a passcode is being entered, a warning tone is emitted from the phone to restrict outgoing calls.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, a main device 1 of the button telephone device accommodates a plurality of button telephones 21 to 27. The main device 1 also includes a main control section 3. It includes a button telephone unit 4, a storage section 5, and an alarm sound sending circuit 6.

On the other hand, each button telephone 2. ~2l1 are subika 21. ~21. have.

Here, the storage unit 5 includes a passcode storage unit 5l that allows a passcode to be used when restricting outgoing calls for each system, and a ξstrip number storage that stores the number of passcode inputs ξss for each telephone. section 52, and an input code storage section 53 that temporarily stores the contents dialed when making an outside line call.
It includes a mistake designation storage unit 54 that stores the number of mistakes in designation, and a digit number storage unit 55 that stores the number of digits of the passcode.

The operation of the above-mentioned button telephone device will be explained with reference to the flowchart shown in FIG.

Now, for example, "4 digits" is set in the number of digits storage section 55 of the storage section 5, and the passcode "4 digits" is set in the passcode storage section 51.
'1111', '3000'". “4000”,
``6000'' and ``4'' are previously input into the ξ path designation storage unit 54 for each system from the key telephone and stored therein.

When the passcode "1111" is input from the first button telephone 21 (N (1100) (step a), the main control section 3 clears the number of mistakes storage section 52 (step b), and the input data is stored as Nα100. (step c), and reads one piece of data from the passcode storage unit 5l (step d).Then, it is determined whether all the pre-registered passcodes have been read (step e). ).

If the passcode is not a space, that is, if the passcode has not been read yet, the passcode read from the passcode storage unit 51 and the code in the input code storage unit 53 are compared (step r), and if they are equal, Na is 100. The number of misses storage unit 52 is cleared (step g), and the process ends.

If they are not equal, the next passcode is read from the passcode storage unit 5l (step h), and the process is repeated.

In this case, the data in the passcode storage unit 5l is “” 1
111”, and the input code also becomes “1111”,
Since they are equal, clear the number of mistakes and end the process. If the passcode has been read, it means that the passcode input from the key telephone was incorrect, so the number of passes is increased (step i).

If the number of ξ passes in the passcode is greater than or equal to the specified number of times, in this case four or more times (step j), the main control unit 3 connects the alarm sound sending circuit 6 to the telephone carrier's communication path (step k), Generate a warning sound from 211 (step l)
. If it is 4 times or less, the process ends.

〔Effect of the invention〕

As explained above, the present invention compares the registered passcode and the entered passcode, and if the passcode is entered incorrectly a certain number of times, the phone that is inputting the passcode generates a warning sound. It is possible to quickly notify others of a passcode input error, and to restrict outgoing calls.
