Alarm threshold:
The FEC Threshold Alarm will be raised if the
distance between successive lost IP frames is below this threshold.
In the Status frame the following parameters are shown:
Lost IP frames:
This counter shows the number of lost IP frames. This

Max burst loss length:
Maximum number of IP frames in a burst loss.
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.
Max IP frames delay:
Maximum number of IP frames between a
corrected data frame and the FEC frame used to correct it.
Latency required:
The time it takes to get a FEC frame and correct the
missing data frame. This time is calculated from Max IP frames delay.
For Column and Row the following status parameters are shown:
UOD port:
The UDP port of the stream.
Bitrate:
The bitrate of the incoming FEC stream.
RTP sequence error:
This counter shows the RTP sequence errors in
