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).
