Description
Field
Shows the current accumulation period, which rolls
into the 24-hour accumulation every 15 minutes. The
accumulation period is from 1 to 900 seconds. The
oldest 15-minute period falls off the back of the
24-hour accumulation buffer.
Data in current interval (seconds elapsed)
Line Code Violations (LCVs) is a count of both
Bipolar Violations (BPVs) and Excessive Zeros
(EXZs) that occur over the accumulation period. An
EXZ increments the LCV by one regardless of the
length of the zero string.
Line Code Violations
For all DS3 applications, a P-bit coding violation
(PCV) error event is a P-bit parity error event. A P-bit
parity error event is the occurrence of a received P-bit
code on the DS3 M-frame that is not identical to the
corresponding locally calculated code.
P-bit Coding Violation
For C-bit parity and SYNTRAN DS3 applications,
the C-bit coding violation (CCV) is the count of
coding violations reported by the C-bits. For C-bit
parity, it is the count of CP-bit parity errors that occur
during the accumulation interval. For SYNTRAN, it
is a count of CRC-9 errors that occur during the
accumulation interval.
C-bit Coding Violation
P-bit errored seconds (PES) is a second with one or
more PCVs, one or more out-of-frame defects, or a
detected incoming AIS. This gauge does not
increment when unavailable seconds are counted.
P-bit Err Secs
P-bit severely errored seconds (PSES) is a second
with 44 or more PCVs, one or more out-of-frame
defects, or a detected incoming AIS. This gauge does
not increment when unavailable seconds are counted.
P-bit Severely Err Secs
Severely errored framing seconds (SEFS) is a second
with one or more out-of-frame defects or a detected
incoming AIS.
Severely Err Framing Secs
The number of unavailable seconds (UAS) is
calculated by counting the number of seconds for
which the interface is unavailable. For more
information, see RFC 1407,
DS3 MIB Variables
.
Unavailable Secs
Line errored seconds (LES) is a second in which one
or more code violations or one or more LOS defects
occurred.
