Embodiment Construction
[0022] A method for processing illegal optical network units by a GPON system according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 2 As shown, a deactivation process of a method for processing an illegal optical network unit by a GPON system includes the following steps:
[0024] In step 1, the OLT sends to the ONU an effective DS frame with a downstream frame synchronization signal PSYNC (Physical Synchronization) used for synchronization between the ONU and the OLT, and uses this signal to synchronize the OLT and the ONU. At this time, the ONU is in the O1 state, which is the initial state.
[0025] In step 2, the OLT sends a PLOAM message (upstream-overhead PLOAM) carrying an upstream overhead parameter indication to the ONU. The PLOAM message is defined by ITU-T G.984.3. At this time, the ONU is in the O2 state, that is, the standby state.
