BACKUP ROW FEC
{No Activity, Online Activity, Offline Activity}
Disabled:
FEC is not enabled (COP3 RTP FEC mode is not
selected)
No Activity:
The backup port is not receiving any row FEC packets

Offline Activity:
The backup is not currently the online port, but it is
receiving row FEC packets
JITTER FILL:
{0 to 99%}
Displays the current jitter buffer fill status
NULL PACKETS:
{count value}
Displays the number of times the modulator has had to
insert null packets into the modulated data stream due to
a missing or erred (and not correctable) data packet.
CORRECTED PACKETS:
{count value}
Indicates the number of times the modulator has had to
use the FEC data stream to generate a missing or erred
data packet.
REORDERED PACKETS:
{count value}
Indicates the number of packets that have been received
out of order. The modulator automatically places these
packets into their correct positions in the transmit data
stream.
