pattern that will be generated. This check box is only available with
SONET/SDH test applications in Through Intrusive with Block &
Replace topology.

Coupled RX to TX check box, when selected (default), allows
coupling both the TX and RX signal with the same test pattern.
For a framed test, the Coupled RX to TX check box is selected and
cannot be cleared.
For an unframed test, the Coupled RX to TX check box is selectable
(selected by default) when All Lanes is selected.

RX Pattern Analysis check box is available with a framed test. When
selected (default), monitors the received traffic pattern. When not
selected, analyzes the live traffic without test pattern thus squelching
the pattern loss, bit error, and no traffic indications.
