Note: See Configuration on page 335 for more information on Test Pattern,

Invert, and User Pattern.

Live Traffic: When enabled, Live Traffic analyzes the line traffic without
test pattern thus squelching the pattern loss, bit error, and no traffic (10G
Ethernet only) indications.

Alarm Analysis

Pattern Loss is declared when the bit error ratio is ≥ 0.20 during an
integration interval of 1 second, or it can be unambiguously identified that
the test sequence and the reference sequence are out of phase.

No Traffic is declared when no BERT traffic has been received in the last
second. Only available when 10G Ethernet is selected.
