This Gauge counts Far End Coding Violations, reported via FEBE, accumulated at the Line layer over the current one-day interval. An admin cares because the daily Far-End CV trend, tracked over successive days, is a way to spot a slowly degrading transmitter or outbound fiber run before it worsens into SES or UAS events that actually affect service. For example, a Far-End CV count that's noticeably higher today than the same time yesterday, even without any alarm tripped, flags gradual degradation on the transmit side worth proactive investigation.
