0x2e112009 The statistics of GPON ONT FEC downstream correctable code words exceed alarm threshold
Today i will discuss about 0x2e112009 alarm. System generates 0x2e112009 The statistics of GPON ONT FEC downstream correctable code words exceed alarm threshold, When the number of gigabit-capable passive optical network (GPON) optical network terminal (ONT) forward error correction (FEC) downstream correctable codec words is larger than the alarm threshold.

Attribute:
| Alarm ID | Alarm Severity | Alarm Type |
|---|---|---|
| 0x2e112009 | Warning | Fault |
Parameters:
| Name | Meaning |
|---|---|
| Alarm threshold of FEC downstream correctable code words | The alarm threshold for the FEC downstream correctable codec words set by the user. |
| Statistics of FEC downstream corrected code words | The number of FEC downstream correctable codec words. |
| Total number of FEC downstream code words | The total number of FEC downstream codec words. |
Impact on the System:
Data is unstably transmitted, packet loss may occur on the upstream service on the ONT, and service quality becomes more deteriorated.
Possible Causes:
- The quality of the optical path is deteriorated.
- The port of OLT is faulty.
Procedure:
- Ensure that the optical fiber is connected properly. Then, check whether the clear alarm is generated.
- Ensure that the optical fiber connector is clean. Then, check whether the clear alarm is generated.
- Check whether the optical fiber is worn out, bent, or broken.
- Replace the optical fiber. Then, check whether the clear alarm is generated.
- Run the display port state command to check whether the ports are normal.
- Reset or replace the PON board. Then, check whether the clear alarm is generated.

Related clear alarm: 0x2e122009 The statistics of GPON ONT FEC downstream correctable code words return to the range within the threshold.
The system monitors the PON-related alarms, which helps to rectify the fault caused by port, optical fiber, or terminal failure or incorrect data configuration, thus ensuring the normal running of PON services.
