Description: The counter associated with the number of Coding Violations encountered by a E3/T3 interface in the history bin.
What is e3t3HistoryLineCVs?
This PerfCounter64 counts Coding Violations encountered by an E3/T3 interface's line layer in the history bin. An admin trends line CV history on a DS3/E3 trunk to catch gradual physical-layer degradation before it escalates into line SES or LOS. If e3t3HistoryLineCVs climbs steadily over several days of history bins on a specific DS3 trunk, the admin schedules a physical inspection of that trunk's connectors before it worsens further.
