This is the day's running total of far-end Unavailable Seconds, counted using the same ten-consecutive-SES rule but applied to the remote-reported statistics. This is effectively the daily downtime figure for the direction of the circuit heading toward the remote site, which matters for SLA purposes if the customer premises equipment sits at that far end. A far-end value of 60 would mean a full minute of the day was counted as unavailable specifically in the direction toward the remote terminal, even if the near-end direction never dropped.
