The present invention relates to a method for switching an extension of a key phone, especially when the taki phone is in a state of 'prohibit use of phone' function, even if it cannot be used because there is no specific number. The present invention relates to a method of switching an extension of a key phone telephone to be changed and used.

In the conventional key-phone telephone, a method of using a key-phone telephone by connecting an extension is shown in FIGS. 1 and 2 of the accompanying drawings. Press the 'Call Forward' button on the key phone (A) and dial the desired number of the desired key phone phone (B).

When the dial is made, the button detecting unit of the key phone main unit detects this and transmits a confirmation tone to the key phone phone A when the extension number of the key phone is correct, and generates an error tone when the extension number is wrong. It transfers to the said key-phone telephone (A).

In addition, when there is a telephone call to the key phone (A) in the 'call forwarding' input completion state, if the key phone phone 'A' is not in the call forwarding state, the ring is output to the key phone 'A' and the key phone 'A' If the call is in a call forwarding state, the ring is output to the designated phone extension 'B'.

However, such a conventional key-phone telephone can receive a call with another person's key-phone telephone because the incoming call can be transferred, but if the ta-key telephone is in the 'prohibit use of phone' function, the ta-key phone is not entered. There is an inconvenience that you can not use the phone.

In addition, when the user wants to use a tachyphone phone in the 'prohibit use of phone' function, there is inconvenience that can be used only by memorizing the usage of the system number system to release the 'prohibit use of the phone' function of the takiphone phone to be used. do.

Therefore, it is an object of the present invention to takiphone all the operation of his key phone phone easily even when there is no specific number (number that can release the 'phone use') when the taki phone phone is in the 'prohibit use of phone' function The present invention provides a method for switching the extension of a key-phone telephone so that the extension can be used as a telephone.

The object of the present invention is to detect the 'line transfer' signal in the takiphone phone 'prohibit use of the phone' function state, and when the 'line transfer' signal is detected, on the LCD of the key phone Displaying an extension number input, requesting input of a password of a jockey phone after inputting the extension number, searching for an input password after the password request, and a predetermined number of times if the password is incorrect as a result of the search; Repeating the requesting and retrieving a password; and if the search result is correct, transferring the extension of the jockey phone to a tachyphone phone, and informing the user through the LCD and the speaker after the call conversion. After using the user, if the CO line is used, it is saved as the jockey phone use history and automatically returns to the original state and terminates. Turning now described in detail based on the accompanying drawings, the present invention is to be accomplished by running the system as follows.

3 is a block diagram of a key phone telephone according to the present invention. The key phone main apparatus 1 controls all key phone telephones connected by an extension, and the data is connected to the data transmission line of the key phone main apparatus 1 to transmit and receive data. A control unit 3 for controlling the overall operation of the first key-phone telephone according to the data received from the data transmitting / receiving unit 2, and a key input unit 4 in the key input unit 4 It is connected to the key detecting unit 5 and the voice transmission line of the key phone main unit 1 to apply this to the control unit 3, the voice transmitted from the key phone main unit 1 under the control of the control unit 3 is a handset ( 6) a second voice that is connected to the keyphone host 1 and a voice transmitter / receiver 7 for transmitting the voice transmitted from the handset 6 to the keyphone host 1; It consists of a key phone telephone 8.

Referring to Figure 4 attached to the operation and effects of the present invention using a key phone applied to the present invention configured as described above in detail as follows.

First, as shown in FIG. 3, when the ring arrives through the trunk line, the key phone main unit 1 connects to each key phone telephone through the connected extension.

For example, when connecting with a first key telephone telephone, data and voice are separated, and data is applied to the data transmitting and receiving unit 2 through a data line, and a voice signal is input to the voice transmitting and receiving unit 7 via a voice line.

Accordingly, the data transmitter / receiver 2 applies the received data to the controller 3, and the controller 3 controls the voice transmitter / receiver 7 according to the received data to transmit the received voice number. ㆍ To be sent to the handset 6.

In case of connecting to the second key phone 8, the same method as described above is performed.

On the other hand, when you want to connect the extension and the trunk line through the first key phone, the user inputs the desired function through the key input unit (4).

The input function is detected by the key detecting unit 5 and then applied to the control unit 3 and then input to the key phone main unit 1 through the data transmitting / receiving unit 2.

Accordingly, the key phone main unit 1 determines whether the input signal is a trunk line or an extension line. In the case of a trunk line, the key phone main unit 1 connects the trunk line to the first key phone telephone, and in the case of an extension, the second key phone 8 or the corresponding key phone telephone ( To the drawing).

Here, when the user assumes his extension keyphone phone as the first keyphone phone and the takiphone phone as the second keyphone phone 8, the first keyphone phone that is his extension is located at the location where the second keyphone phone 8 is located. When you want to forward your key-phone phone:

In the above description, it is assumed that the second key phone 8 is in a state of 'prohibit use of the phone' function and the user does not know the specific button of 'prohibit use of the phone'.

First, the user presses the "Current line switch" button through the key input unit (not shown) in the second key phone telephone (8).

When the 'Current line switch' button is pressed, the key phone main unit 1 recognizes this and displays an extension number (meaning the extension number of the first key phone) on the LCD of the second key phone. .

Thereafter, when the extension number of the first key phone is input through the user, the user enters a "password" on the LCD of the second key phone 8 in the following operation. Here, "password" means a password of the first key phone.

After that, the user enters the password of the first key phone, and the key phone main unit 1 searches for the input password.

If the password entered in the search is incorrect, the password is re-entered on the LCD of the second key phone 8.

If the password is incorrectly displayed as described above three times, if the password is incorrect even if the password is entered three times, an error tone is sent to inform the user.

On the other hand, when the password is correct, the key phone main unit 1 performs the "Current line switch" and indicates that the preparation is completed on the LCD of the second key phone (8) and generates a confirmation tone to inform the user.

Then, when the user completes the use of the second key phone (8), the key phone main unit (1) if the use of the CO line will be stored as the trunk line use history of the first key phone phone, if the use of the extension rather than the use of the CO line It will not save the details and then return to the original state to release the 'Current line switch'.

When the CO line is used in the above, the reason for storing the usage history on the first key phone is because the user can know the exact state of the CO line use when checking the CO line usage history.

As described in detail above, the present invention has the effect of promoting the convenience of life because it can be used in an emergency even when the tachyphone phone is in the 'prohibit use of phone' function, and also without knowing the function number system of the tachyphone phone. There is also an effect that can be convenient to use the same as the use of his own phone.
