ES
(Errored Second) - For ESF mode, an errored second is defined as a second with one or more Path
Code Violations (PCVs), or one or more Out of Frame (OOF) defects, or one or more Controlled Slip
events, or a detected AIS (blue alarm) defect. For D4 (SF) mode, the presence of Bipolar Violations
(BPVs) also triggers an errored second.

SES
(Severely Errored Second) - For ESF mode, an
SES
is a second with 320 or more PCVs, or one or
more OOF defects, or a detected AIS defect. For D4 (SF) mode, an
SES
is a second with one or more
Framing Error events, or an OOF defect, or at least 1544 Line Code Violations or more.

error.

LCV
(Line Code Violation) - A Line Code Violation is defined as a Bipolar Violation (BPV), not including
the B8ZS code word if B8ZS is employed. The number displayed is
LCV
events, which is defined as one or
more BPVs in a one-second interval.

SLP (Slip Error Event) - This occurs when a received frame is either repeated or deleted. A

error
indicates a timing problem.

(Unavailable Seconds) - When 10 consecutive
SES
s have been logged, the unit is declared in an
unavailable state, the 10
SES
s are cleared, and the Unavailable Seconds count begins to increment starting
with 10. The unavailable state is cleared when 10 consecutive non-SES seconds have occurred.
