Abstract

PURPOSE: An Internet/PSTN combinable telephone set is provided to separate power for an Internet phone and power for a telephone line so as to normally use the PSTN phone even though the power of the Interphone is interrupted. CONSTITUTION: An Internet/PSTN combinable telephone set is comprised of an Internet phone signal processing part(110), a telephone line signal processing part(120), a DC/DC converter(130), a control part(140), a handset(150), the first relay(160), the first and second transformers(170,171), and a handset power supply part(180). The Internet phone signal processing part(110), connected to a computer, receives digital DC power(DVCC) for an Internet phone and executes an Internet phone function. The telephone line signal processing part(120), connected to a telephone line, outputs analog AC power(AVCC) and executes a PSTN phone function. The DC/DC converter(130) receives digital DC power, converts it into AC power, rectifies it, and outputs DC power(VAA). The control part(140) controls the usage of the Internet phone and the PSTN phone. The handset(150) receives the other side's voice and transmits a user's voice. The first relay(160) connects the handset(150) to the Internet phone signal processing part(110) or the telephone line signal processing part(120) according to the control of the control part(140). The first and second transformers(170,171) are connected between the Internet phone signal processing part(110) and the first relay(160) in order to separate the digital DC power(DVCC) supplied to the Internet phone signal processing part(110) and the power supplied to the telephone line signal processing part(120) and the handset(150). The handset power supply part(180) interrupts the DC power(VAA) outputted from the DC/DC converter(130) or supplies it to the handset(150) according to the magnitude of the AC power(AVCC) outputted from the telephone line signal processing part(120).
