The number of errored seconds encountered by a DS1 interface in one of the previous 96, 15-minute intervals.
SESs (severely errored seconds) (dsx1IntervalSESs)
The number of severely errored seconds encountered by a DS1 interface in one of the previous 96, 15-
minute intervals.
SEFSs (severely errored frame seconds) (dsx1IntervalSEFSs)
The number of severely errored framing seconds encountered by a DS1 interface in one of the previous 96,
15-minute intervals.
