A facsimile system automatically confirms a connection status of a facsimile system and a telephone handset upon a power-up by sensing the power. The facsimile system includes first and second connection terminals, and a relay for forming a communication path between the first and second connection terminals and a parallel connection telephone handset according to control of a controller, and for forming a communication path between the first connection terminal and a modem during a facsimile mode. In order to automatically confirm a line connection, the facsimile system generates a facsimile mode control signal upon a power-up, and detects a dial tone; and then, generates a waiting mode control signal if the dial tone is detected, and generating a line connection request message if the dial tone is not detected.
