This value specifies, in centiseconds (0, or 1 to 1000), an additional delay a MEP in this Maintenance Association waits before declaring a connectivity fault, added on top of the standard 3.5x CCM-interval rule; zero means no additional delay. An admin increases this to reduce false-positive fault declarations on a path prone to brief transient CCM losses, at the cost of slightly slower genuine fault detection. It's tuned per Maintenance Association based on how much transient instability that specific service's path is known to experience.
