This is the day's running total of Severely Errored Seconds reported by the remote terminal, accumulated via FEBE indications since the day began. A high far-end daily SES total with a low near-end daily SES total over the same day tells an admin that whatever equipment or fiber run this box transmits over toward the remote site is the more troubled half of the circuit. A far-end reading of 15 against the default daily threshold of 7 would represent a clearly bad day for the outbound direction of this path.
