Description: A DS1 Severely Errored Framing Second (SEFS) is a count of one-second intervals containing one or more SEF events. A Severely Errored Framing (SEF) event is declared when an error in the A1 octet and an error in the A2 octet of a framing octet pair (i.e., errors in both framing octets), or two consecutive invalid and/or nonsequential Path Overhead Identifier octets are detected.
