Abstract
PURPOSE:To smoothly switch lines at the time of receiving by detecting the off-hook of a telephone set and switching the lines to facsimile at the time of detecting a facsimile calling signal continuously over a prescribed time. CONSTITUTION:When the receiving is executed from a facsimile communications network, a telephone set 3 is rung and the handset of the telephone set 3 is lifted up, the polarity of the direct current of a line L2 is inverted, the off-hook is detected by an off-hook detecting circuit 8 and the detection result is supplied to a system control part 6. Then, when the timer of the control part 6 is started up and the facsimile calling signal through the facsimile communications network is continued for a reference time up to a time up, a switch 1 is switched by the control part 6, lines L1 and L2 are connected to a transformer 2, and a facsimile action is automatically made. Thus, the switching of the lines to the facsimile equipment at the time of the receiving can be smoothly executed.
