Line Stats
Circuit Name Name of the circuit associated with this line.
Interval The current interval.
LESs The number of line errored seconds (LESs) in the current interval.
An LES is a second in which one or more coding violations
occurred or one or more LOS defects were detected.
SEFSs The number of severely errored framing seconds (SEFSs) in the
current interval. An SEFS is a second with one or more OOF errors
or an AIS defect.
UASs The number of unavailable seconds (UASs) in the current interval.
LCVs The number of line coding violations (LCVs) in the current
interval. A line coding violation is a count of both bipolar
violations (BPVs) and excessive zero (EXZ) error events.
Pbit Status
Circuit Name Name of the circuit associated with this line.
Interval The current interval.
PESs The number of P-bit errored seconds (PESs) in the current interval.
A PES is a second with one or more P-bit coding violations,
one or more OOF defects, or a detected incoming AIS. The PES
does not increment when counting UASs.
PSESs The number of P-bit severely errored seconds (PSESs) in the
current interval. A PSES is a second with 44 or more PCVs, one or
more OOF defects, or a detected incoming AIS. The PSES value
does not increment when counting UASs.
UASs The number of unavailable seconds (UASs) in the current interval.
PCVs The number of P-bit coding violations (PCVs) in the current
interval. For all DS3/E3 applications, a coding violation error event
is a P-bit Parity Error event. A P-bit Parity Error event occurs
when the DS-3/E-3 M-frame receives a P-bit code that is not
identical to the corresponding locally calculated code.
