A signal is input to the CID conversion circuit 113 through a signal level adjuster (not shown) and a CAS filter (not shown) to adjust the balance of the signal applied to the CID converter 113. The signal decoded by the CID conversion circuit 113 is input to the MCU 130, and the signal input to the MCU 130 is output through the LCD 160.

In this case, the CID conversion circuit 113 and the MCU may receive a decoded signal in the on / off hook 117 state, and the CID conversion circuit outputted to the LCD 160 at the off hook 117. 113) displays the calling party's name, phone number, address, and year, month, day, hour, minute, and second of the call attempt.

At the same time, the phone number stored in the phone memory 140 and the CID of the incoming call can be checked so that the user can automatically reject the unwanted call.

Also, if you do not know who the called party is (on a hook), the user can operate the preset button by the user's name, phone number, address, and year, month, day, hour, Minutes and seconds are output to the LCD 160 so that the user can determine whether the user wants the phone to stop communication.

5 is a block diagram showing a system of the USB controller of the present invention. As shown in the drawing, a voice signal applied through the PSTN network A is input to the Spitz network 112 through the line interface 110. The analog voice signal input through the spitz network 112 is converted into digital data through a USB controller 180 including a USB driver 181 and a PCM codec 182, and then the data is converted into digital data. Are transferred and stored on the hard disk.

The digital data converted as described above is compressed using a compression algorithm and stored on the hard disk, and the stored data can be reproduced through the application S / W 210 according to a user's selection.

6 is a block diagram showing a system of the DTFT receiver according to the present invention. As shown in the drawing, a signal applied through the PSTN network A is transmitted to the DTMF receiver 114 via the line interface 110. After inputting and transmitting the signal input to the DTMF receiver 114 to the MCU 130 through a decoding process, the user can transmit and confirm the automatic response, voice message, and the phone (using the computer main body 200). Through 100) it is possible to additionally perform the home appliance control function.

FIG. 7 is a block diagram illustrating a ringer system of the present invention. When a call of a telephone is generated through the PSTN network A as shown in the drawing, the ring signal input to the ringer 115 is an AMP ( 122)) and output to the speaker 125 and at the same time it is input to the MCU 130 through the electronic relay 116, and then input to the computer main body 200 through the USB controller 180 can check the status of the call. have.
