This sub-page will only appear if the unit is enabled with FEC. 
Enable FEC: Tick this box to enable use of FEC.  
Alarm threshold: This parameter controls the frequency of lost frames 
that should cause activation of the ‘FEC Threshold Exceeded’ alarm. 
The threshold is configured in the unit of frames between losses, 
causing the alarm to be activated if the number of frames received 
between two losses falls below the configured number. 
In the Status frame the following parameters are shown: 
Lost IP frames: This counter shows the number of lost IP frames. This 
means packets which remain uncorrected. 
Corrected IP frames: This counter shows the number of IP frames 
corrected by the FEC engine.  
Duplicated IP frames: This counter shows the number of duplicated IP 
frames received. 
Columns (L): This shows the number of columns in the incoming FEC 
stream. 
Rows (D): This shows the number of rows in the incoming FEC stream.
