The ONU sends its SN to the OLT. After receiving the SN of the ONU, the OLT allocates a temporary ONU ID to the ONU. -- **`O4` Ranging:** The OLT sends a ranging request to the ONU. After receiving the ranging request from the OLT, the ONU responds with a message carrying its SN and ONU ID. The OLT calculates the compensation delay and sends it to the ONU in a message. After receiving the message, the ONU sets the compensation delay accordingly. -- **`O5` Operation:** The OLT sends a password request to the ONU. The ONU returns a password to the OLT. -- **`O6` Intermittent LODS state.** -- **`O7` Emergency Stop state.** - -The password is not configured on the OLT. If the automatic discovery function is enabled on the PON port of the OLT, the OLT reports an ONU auto-discovery alarm to the CLI or NMS. The ONU goes online normally only after being confirmed. - -```mermaid -graph TD - O1[O1 Initial state] -->|Downstream Synchronization attained| O2[O2-03 Standby-Serial number] - O2 -->|Assign ONU-ID Ploam and Equalization delay assigned| O4[O4 Ranging State] - O4 -->|Ranging Time PLOAM and Equalization delay assigned| O5[O5 Operation] - O5 & O4 & O2 -->|Loss of downstream syncronizzation| O6[O6 Intermittent LODS state] - O2 ---->|Disable S/N Request| O7[O7 Emergency stop state] - O2 -->|Broadcast deactivate ONU-ID Request| O1 - O4 --->|TO1 time expires| O2 - O4 & O5 ---->|Disable S/N Request| O7 - O7 ---->|Enable S/N Request| O1 - O6 ---->|TO2 timer expires| O1 - O6 -->|Downstream Synchronization restored| O5 - O5 & O4 ---->|Deactive ONU-ID Request| O1 -``` - -# Fake O5 Status - -This known issue with Alcatel/Nokia OLT giving fake `O5` ONU Status, OLT will hold OMCI Provisioning until correct OMCI Information - -It happens when the OLT detects that the ONT is `drunk`.
