#### Details

For ESF and E1-CRC links, an errored second is a second with one or more path code violations, one or more out-of-frame defects, one or more controlled slip events, or a detected AIS defect.

For D4 and E1-noCRC links, the presence of bipolar violations also triggers an errored second.

This value is not incremented during an unavailable second.
