UAS-L
Far-End Line Unavailable Seconds (UAS-L) is a count of the seconds
when the line is unavailable at the far end. A line becomes unavailable at
the far end when ten consecutive seconds occur that qualify as SES-LFEs
and it continues to be unavailable until ten consecutive seconds occur that
do not qualify as SES-LFEs.
FC-L
Far-End Line Failure Count (FC-L) is a count of the number of far-end
line failure events. A failure event begins when RFI-L failure is declared,
and it ends when the RFI-L failure clears. A failure event that begins in
one period and ends in another period is counted only in the period where
it began.
