Title: Subscriber circuit feeding system
Inventor: YOSHINO HARUYUKI
IPC: H04Q1/28
Filed: 1984-06-06
Abstract: PURPOSE:To attain miniaturization of a subscriber circuit subject to low power consumption by providing a DC/AC converting means in common and providing an AC/DC means at each subscriber circuit. CONSTITUTION:A DC voltage of -48V from an exchange main power supply is inputted to a DC/AC converting circuit 5, and an AC voltage is generated in the secondary winding of a transformer T and fed to plural subscriber circuits 21 via a bus 6. The AC voltage is inputted to an AC/DC converting circuit 7 in each subscriber circuit 21, and after the voltage is rectified in full wave by a full wave rectifier RF, it is smoothed, converted into a DC voltage and fed to a talking current supply circuit 31 so as to apply the talking current to the subscriber lines L1, L2. Since the talking current supply DC voltage fed to the circuit 31 is set to apply the same talking current to the subscriber terminal equipment when the total value of the line resistor and the subscriber terminal of the subscriber lines L1, L2 is equal, the power consumed in the circuit 31 is almost halved.
