Severely Errored Seconds -
Errored Seconds (LES) - A Line Errored Second, according to T1M1.3, is a second in which one or
more Line Code Violation error events were detected.

Bipolar Violation (BPV) Error Event -A BPV error event for an AMI-coded signal is the occur-
rence of a pulse of the same polarity as the previous pulse. A BPV error event for a B8ZS- or HDB3-
coded signal is the occurrence of a pulse of the same polarity as the previous pulse without being a
part of the zero substitution code.

Figure 7-1: The T1 History Screen

7.1.5 T1 History (Last 24 Hours)

The T1 history for the last 24 hours for both spans is tracked and displayed at 15 minute intervals.
