This read-only Gauge reports the number of Bursty Errored Seconds encountered by this DS1 interface over the previous 24-hour interval, the daily-total counterpart to dsx1IntervalBESs. This gives a single daily figure for the moderate-severity error category, useful for a same at-a-glance daily trend as dsx1TotalESs but specifically isolating the burst-error character rather than all errored seconds. An engineer distinguishing a DS1 with occasional isolated bit errors from one with recurring error bursts (perhaps from intermittent electrical interference) would track dsx1TotalBESs daily to spot the bursty pattern developing over time.
