This Counter32 accumulates the number of Errored Seconds caused by Line Code Violations on this DS1 interface. This gives an admin a time-based severity measure rather than a raw violation count, showing how many one-second intervals were affected, which correlates more directly with perceived call impact. For instance, an admin comparing lES against lCV would use a high lES relative to lCV to judge whether violations are spread across many seconds or clustered in a few bad ones.
