The present invention relates to a ring volume control method of a telephone, and more particularly, to a ring volume control method of a telephone using a branched telephone to control the ring volume of the telephone with a branched telephone.

In general, a telephone for controlling a ring volume and a received volume of a telephone using a conventional optical dial includes a keypad 10, a microprocessor 20, a lamp driver 30, and a memory 40 as shown in FIG. , Timer 50, volume control unit 60 is configured to include.

In the figure, the keypad 10 outputs a volume telephone signal corresponding to a volume button input and a volume control signal corresponding to a dial button based on a user's operation signal, and the microprocessor 20 outputs the volume switching signal. If it is input, it checks whether a call is in progress and generates a control signal for driving the corresponding lamp, and generates a control signal for adjusting the ring volume and the received volume of the phone according to the input volume control signal, and the timer 50 Generate control signals for operation.

In addition, the lamp driver 30 generates a switching signal for switching the driving of the corresponding optical dial button lamp based on the driving control signal from the microprocessor 20, and the memory 40 receives the input ring volume level and the reception signal. Save the volume level.

In addition, the timer 50 counts for a predetermined time set based on the operation control signal from the microprocessor 20, and the volume adjusting unit 60 is based on the control signal for volume adjustment from the microprocessor 20. Adjust the ring volume and incoming volume of the phone.

Next, referring to the flowchart of FIG. 4 in the volume control process in the telephone including the above-described configuration unit, first, when a volume button is pushed based on a user's operation signal and a signal for volume adjustment is inputted ( Step 400), the timer 50 is operated (step 402), the call is checked (step 404), and if busy, the button lamp corresponding to the currently set received volume level among the dial buttons is turned on to turn the user on. Recognizes the reception volume currently set at step 406, and if not in a call, switches the button lamp corresponding to the ring volume level currently set during the dial button to on (step 408).

Then, the controller detects whether the dial button to change the volume is input (step 410), and if so, turns off the button lamp turned on in step 406 or 408, turns on the button lamp corresponding to the dial button, and then calls. If not, the received volume is adjusted. If not, the ring volume is adjusted (step 412), and the timer is reset (step 414).

Next, it detects whether there is an input of the volume button (step 416), turns off the button lamp which is on when there is an input (step 420), and if the call is in the memory 40 at the received volume level, If not, the volume level corresponding to the dial button input above is stored as the ring volume level (step 422).

On the other hand, if the dial button input for changing the volume for the time set in step 410 is up (step 418), the process goes to step 420.

However, since the ring volume and the received volume adjustment method as described above can be controlled by the user's input directly from the telephone equipped with the above function, there is a problem that the user is inconvenient, and in general, by sharing one trunk line in parallel Another branched telephone that is connected and used to find a way to perform the ring volume control function.

Accordingly, the present invention provides a ring volume control method for a telephone using a branched telephone, which is designed to meet the needs as described above, so that the ring volume of the telephone can be controlled in another branched telephone.

In order to achieve the above object, the present invention provides a method for controlling a ring volume of a telephone by using another telephone branch and connected in parallel, the method comprising: detecting a telephone loop of the other branch telephone, and the branched other Detecting whether a driving signal for capacity control from another branch phone is input when the telephone loop of the telephone is turned on; and volume control is possible to another branch phone when the driving signal for volume control is input. Transmitting a meaning tone and detecting that a signal for volume conversion from another branch phone is input; and when a signal for volume conversion is input, a volume level corresponding to the input signal is stored in a memory. When the next ring sound occurs, adjusting the ring volume to the volume level stored in the memory It provides a ring volume control method for a telephone using a branched telephone comprising a.

Other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a telephone employed to explain a volume control method of a telephone using a branched telephone according to the present invention. As shown in the figure, the telephone employed in the present invention includes a branched telephone 10, a loop detector 20, a microprocessor 30, a telephone call circuit 40, a DTMF receiver 50, a tone generator 60, a memory 70, and a volume controller 80.

In the figure, the branched telephone 10 is a telephone which is connected in parallel to the same trunk line as the telephone to control the ring volume, and the loop detector 20 detects a loop on / off state of the branched telephone. To transmit the detection signal to the microprocessor 30.

The microprocessor 30 controls the overall operation of the phone, receives the volume control signal input from the branched phone 10 from the DTMF receiver 50, and performs a ring volume adjustment operation corresponding thereto.

In addition, the telephone call circuit unit 40 turns on / off the telephone loop for the call with the other subscriber connected through the trunk line based on the control signal from the microprocessor 30.

Meanwhile, the DTMF receiver 50 receives a dual tone multi frequency signal (DTMF) signal for controlling the volume from the branched phone 10 through the branched line and transmits it to the microprocessor 30.

In addition, the tone generator 60 generates a tone to inform the user of the branch telephone 10 that the volume can be controlled based on the control signal from the microprocessor 30.

In addition, the memory unit 70 is a means for storing the set or reset volume level, the volume level received from the DTMF receiver 50 under the control of the microprocessor 30 at the time of resetting from the branched telephone 10. Is input and stored.

Finally, the volume adjusting unit 80 generates a ring tone corresponding to the volume level stored in the memory 70 when the ring signal is input, based on a control signal from the microprocessor 30, thereby omitting a ring tone. Output to the speaker.

Next, the volume control operation of the telephone using the branched telephone according to the preferred embodiment of the present invention in the telephone including the above-described configuration will be described in detail with reference to the flowcharts of FIGS. 1 and 2.

First, by detecting a telephone loop of the branched telephone 10 connected in parallel to the same trunk line (step 200), if the loop is on, the DTMF receiver 50 is in a standby state and its own station number (for example, If the phone number is 876 to 1234, it is detected whether 876 is input (step 202), and if so, it detects whether a dial tone from the exchange is cut off and if a specific button (e.g., # or *) is set. (Step 204).

On the other hand, when an input other than the station number + specific button as described above is detected in the above step 202, 204, the user recognizes that the operation is not for volume control and exits and returns to this routine.

In addition, when a specific button is input to the terminal 204, the branch line is generated by generating a tone as a means for informing the user who wants to control the volume using a branched phone by controlling the tone generating unit 60. The telephone is sent to the branched telephone 10 through the line (step 208).

Next, it is detected whether a dial button (for example, 0: volume off, 9: volume maximum) is input from the branched telephone 10 (step 210), and if so, the DTMF receiver 50 The ring volume level received in the memory 70 and set in the memory 70 is switched to the ring volume level received in the DTMF receiver 50 and stored in the memory 70 (step 212).

Then, when the ring signal is input, the ring sound is generated at the ring volume reset based on the above-described process.

As described above, according to the present invention, by adjusting the ring volume of the telephone in the branch telephone, it is possible to provide more convenience to the user.
