This sets the threshold, in microseconds, for the single maximum jitter value observed that triggers a fault when exceeded during a delay-measurement test, capturing a worst-case jitter spike distinct from the average-jitter threshold's concern with sustained behavior. An admin sets this to catch a brief but severe jitter event (for example a single large buffering delay) that a smoothed average jitter figure might not reveal at all. For example, a service passing comfortably on average jitter could still trigger a fault from a single spike exceeding cienaCesCfmDelayMsgMaximumJitterThreshold, flagging a transient problem an average-only view would have masked.
