Abstract

PROBLEM TO BE SOLVED: To prevent consumption of standby power of an optical subscriber line-terminating device in an imaging system. SOLUTION: When a user turns on the power for STB 16a for electrical lamp lines, a state signal showing a state of being used is sent from the STB for electrical lamp lines to the electrical lamp lines. This signal is received at an electrical lamp line signal receiving unit 8 of ONU 11a, and the electrical lamp line signal receiving unit sends a power-on signal to a power control unit 7. The power control unit receives the signal and turns on power supply to V-ONU 5. When the user turns off the power for STB for electric lamp lines, a state signal, showing a state of not being used, is sent from the STB for electric lamp lines to the electrical lines and received at the electrical lamp line signal receiving unit. The electrical lamp line signal receiving unit sends a power-off signal to the power control unit. The power control unit receives the signal and turns off the power supply to V-ONU.
