INTERFACES (T1[0]) > STATUS > PERFORMANCE > ES
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.
INTERFACES (T1[0]) > STATUS > PERFORMANCE > SES
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.
INTERFACES (T1[0]) > STATUS > PERFORMANCE > SEF
SEF (Severely Errored Frame) - An SEF condition occurs when 2 out of 6 consecutive frame bits are in
error.
INTERFACES (T1[0]) > STATUS > PERFORMANCE > FS
FS (Frame Slip) - A frame slip is defined as one or more frame bit errors in a one-second interval.
INTERFACES (T1[0]) > STATUS > PERFORMANCE > LCV
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.
INTERFACES (T1[0]) > STATUS > PERFORMANCE > SLP
SLP (Slip Error Event) - This occurs when a received frame is either repeated or deleted. A SLP error
indicates a timing problem.
INTERFACES (T1[0]) > STATUS > PERFORMANCE > UAS
UAS (Unavailable Seconds) - When 10 consecutive SESS have been logged, the unit is declared in an
unavailable state, the 10
SESS are cleared, and the Unavailable Seconds count begins to increment starting
with 10. The unavailable state is cleared when 10 consecutive non-SESs have occurred.
INTERFACES (T1[0]) > STATUS > ALARMS
Displays current alarms and alarm history for T1 interface.
