METHOD AND APPARATUS FOR PROCESSING ALARM UNDER POWER-SAVING MODE IN PASSIVE OPTICAL NETWORK (PON) SYSTEM

摘要

Disclosed in the present invention are an alarm processing method and device for a PON system in power-saving mode, for solving the technical problem that the PON system cannot process the alarm or exception message after the ONU enters power-saving state and the management server is misled to deem that the system is abnormal. In the present invention, when the OLT detects the alarm generated for a certain ONU, it acquires the current power-saving working state of the ONU, and if the ONU is currently in power-saving state (such as doze state, i.e. Tx mode), the OLT suppresses, discards or shields the relevant alarm by the ONU currently in power-saving state. By way of the present invention, the alarm processing pressure can be alleviated and the real state of the ONU can be reflected.
