Embodiment Construction
[0071] The embodiment of the present invention is applied to a time synchronization system, which mainly includes: OLT, ONU, and base station; the time synchronization system realizes time synchronization by transmitting time stamps through PTP messages; wherein, the OLT is used as a slave clock Slave and The upper-level clock source device interacts with PTP messages, realizes time synchronization between the OLT and the upper-level clock source device by transferring time stamps, and sends the adjusted local time to the ONU, so that the ONU realizes synchronization with the ONU. The time synchronization of the OLT; at the same time, the OLT, as the main clock Master, performs PTP message interaction with the base station through the ONU, and makes the base station realize the time synchronization with the OLT by passing the time stamp; the embodiment of the present invention The OLT directly transmits the attribute parameters in the PTP message obtained from the upper-level c...
