Configuration
Note: See Configuration on page 405 for more information on Test Pattern,
Invert, and User Pattern.
³
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. Live Traffic is not available
when the Unframed is selected.
³
Coupled RX/TX: Allows coupling both TX and RX signal with the same
pattern configuration. This setting is enabled by default and only
configurable when the Overwrite check box is selected (see Pattern
TX on page 405).
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.
