What is sEFS?

This Counter32 accumulates the number of Severely Errored Framing Seconds encountered on this DS1 interface. A rising sEFS count indicates the line lost frame synchronization badly and frequently, which typically causes audible clicks or dropped calls rather than just minor quality degradation. For example, a line with a high sEFS count alongside customer complaints of dropped calls would point an admin toward a framing/synchronization root cause.
