FarEnd Cbit Stats
Circuit Name of the circuit associated with this line.
Interval The current interval.
CESs The number of C-bit errored seconds (CESs) in the current interval.
A CES is a second with one or more CCVs, one or more OOF
defects, or a detected incoming AIS. This count is only for C-bit
Parity DS3 applications. The CES value does not increment when
counting UASs.
CSESs The number of C-bit severely errored seconds (CSESs) in the
current interval. A CSES is a second with 44 or more CCVs, one or
more OOF defects, or a detected incoming AIS. This count applies
only to C-bit Parity DS3 applications. The CSES value does not
increment when counting UASs.
UASs The number of unavailable seconds (UASs) in the current interval.
CCVs The number of C-bit coding violations (CCVs) in the current interval.
For C-bit Parity DS3 applications, this is the count of coding
violations reported via the C-bits. For C-bit Parity, it is a count of
C-bit parity errors occurring in the accumulation interval.
DS3 Plcp Stats
Circuit Name of the circuit associated with this line.
Interval The current interval.
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.
