(or Length test status in the case of 2-way Autotest) is
fail.
•Pass/fail method selection:
For 2-way Autotest: If ‘WC’ is selected, the worst-case loss
value will be used to determine the test status. If ‘AV’ is
selected, the average loss value will be used to determine
the test status.
For 1-way Autotest: Worst case loss value will always be
used to determine the test status regardless of the selected
pass/fail method.
