SEF
Accumulates the number of Severely Errored Framing Seconds in the 15-minute interval. A
SEF is a second in which one or more Out of Frame (OOF) defects or a detected incoming AIS
occurred.
UAS
Accumulates the number of Unavailable Seconds in the 15-minute interval. The DS3 interface
is unavailable from the onset of 10 contiguous PSESs, or the onset of a condition leading to a
RAI failure state. If the condition leading to the failure was preceded by one or more
contiguous PSESs, the unavailability starts from the onset of these PSEs. Once unavailable
and if no failure is present, the DS3 becomes available at the onset of 10 contiguous seconds
with no PSESs.
LES
Accumulates the number of Line Errored Seconds in the 15-minute interval. An LES is a
second in which one or more P-bit or C-bit parity errors or Loss of Signal (LOS) defects
occurred.
LCV
Accumulates the number of Line Code Violations in the 15-minute interval. This includes both
Bipolar violations (BPVs) and Excessive Zeros (EXZs).
PCV
Accumulates the number of P-bit Code Violations in the 15-minute interval.
CCV
Accumulates the number of C-bit Code Violations in the 15-minute interval.
STATUS
The Status column shows the nature of the errors calculated in each of previous ten categories.
Any of the following Status codes may appear in this column depending upon how the errors
occurred. Possible values for this column are Y (receive yellow alarm), X (transmit yellow
alarm), A (receive AIS), I (transmit AIS), F (receive loss of frame), S (receive loss of signal),
L (loopback) or T (test).
