0x2e112009 GPON ONT FEC exceed alarm threshold

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:

  1. Ensure that the optical fiber is connected properly. Then, check whether the clear alarm is generated.
  2. Ensure that the optical fiber connector is clean. Then, check whether the clear alarm is generated.
  3. Check whether the optical fiber is worn out, bent, or broken.
  4. Replace the optical fiber. Then, check whether the clear alarm is generated.
  5. Run the display port state command to check whether the ports are normal.
  6. 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.
