COMMUNICATION METHOD FOR OPTICAL COMMUNICATION SYSTEM, OPTICAL COMMUNICATION SYSTEM, SLAVE STATION APPARATUS, CONTROL DEVICE, AND COMPUTER PROGRAM |
摘要 |
The control device includes a power-saving control unit that intermittently repeats, based on a power saving permission signal transmitted from the master station apparatus, power saving control in which the slave station stops or reduces power supply to a transmitter or a receiver for a predetermined pause duration while maintaining a communication link and a monitoring unit that monitors out of synchronization by comparing a synchronization signal received from the OLT and a time of the ONU. The control device shifts from a registered state to a deregistered state when the monitoring unit detects the out of synchronization. On the other hand, after the pause duration of the power saving control, the control device suppresses the shift to the deregistered state due to the detection of the out of synchronization.
