Pbit Status
Circuit 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 codin
violations,
one or more OOF defects, or a detected incomin
AIS. The PES
does not increment when countin
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 incomin
AIS. The PSES value
does not increment when countin
UASs.
UASs The number of unavailable seconds (UASs) in the current interval.
PCVs The number of P-bit codin
violations (PCVs) in the current interval.
For all DS3/E3 applications, a codin
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
correspondin
locally calculated code.
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 incomin
AIS. This count is only for the
C-bit Parity DS3 applications. The CES value does not increment
when countin
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 incomin
AIS. This count applies
only to C-bit Parity DS3 applications. The CSES value does not
increment when countin
UASs.
UASs The number of unavailable seconds (UASs) in the current interval.
CCVs The number of C-bit codin
violations (CCVs) in the current interval.
For C-bit Parity and SYNTRAN DS3 applications, this is the count of
codin
violations reported via the C-bits. For C-bit Parity, it is a
count of C-bit parity errors occurrin
in the accumulation interval.
