This read-only value reports whether cells have been lost on this channel for at least the duration configured in cesCellLossIntegrationPeriod, flipping to loss(2) once that sustained condition is detected and back to noLoss(1) once loss stops. An administrator monitors this as a debounced loss indicator that filters out brief, momentary cell loss from genuinely sustained problems, avoiding false alarms from transient blips. A channel repeatedly toggling between loss and noLoss states suggests an intermittent problem worth investigating even though each individual episode may be brief.
