Abstract
PURPOSE:To obtain required sufficient power even if line resistance connecting to an operating equipment is large by monitoring an input voltage of a power supply means and feeding back the voltage information to a station equipment so as to supply a proper voltage to the power supply means of the operating device from the feeding means of the station device. CONSTITUTION:A voltage monitor section 22 and a voltage information transmission section 24 are provided to a terminal equipment 2 and a voltage information reception section 14 and a voltage control section 12 are provided to an exchange 1 to control an output voltage of a feeding circuit 10. Thus, required sufficient power is supplied to a power supply circuit 20 regardless of the line resistor 300. Moreover, the station exchange 1 supplies a required minimum proper voltage to the terminal equipment 2. Since the input voltage to the terminal equipment 2 is constant regardless of the resistance of the line resistor 300, the design of the power supply circuit 20 is facilitated and the manufacture of the circuit 20 is made inexpensive.
