Mode The error correction mode:
• Off: No error correction is used.
• FEC74: Applies IEEE 802.3 Clause 74 Fire Code Forward Error Correction.
•
FEC108:
Applies IEEE 802.3 Clause 108 Reed Solomon Forward Error Correction.
Corresponding equipment sending or receiving these media streams must also be
configured with the same error correction method. Otherwise the link will fail.
Uncorrected
FEC Error
Corrected FEC
Error
The current number of detected errors at the physical layer.
• Corrected errors are errors that the FEC algorithm was able to remove.
• Uncorrected errors are errors that the FEC algorithm was unable to remove as the bit
stream is too damaged.
NOTE: The error counters only work when the Mode is set to FEC108 or FEC74.
Reset Counter Clear the number of errors shown above. When Reset is clicked, the current date and time
is shown as a record of how long the corresponding error counter has been running since
the last reset.
