The bit 'ds1ThresholdReached15MinLCV(4)' indicates that the 15 minute threshold for line code violations has been reached.

The bit 'ds1ThresholdReached15MinLES(5)' indicates that the 15 minute threshold for line errored seconds has been reached.

The bit 'ds1ThresholdReached15MinPCV(6)' indicates that the 15 minute threshold for path coding violations has been reached.

The bit 'ds1ThresholdReached15MinSES(7)' indicates that the 15 minute threshold for severely errored seconds has been reached.

The bit 'ds1ThresholdReached15MinSEFS(8)' indicates that the 15 minute threshold for serverly errored framing seconds has been reached.

The bit 'ds1ThresholdReached15MinUAS(9)' indicates that the 15 minute threshold for unavailable seconds has been reached.

What is adGenAOSDs1PreviousThresholdAlarms?

This read-only bit-string captures the alarm state before the most recent transition, enabling trend analysis of error conditions. Analysts use it to track whether thresholds are clearing or worsening, informing whether to escalate or prepare for recovery. An example shows CSS threshold was crossed previously but now only BES is active, suggesting error pattern changes.
