This object indicates whether the Underflow component of the Adjustment TCA feature configuration attributes are configured in a way for preemptive Adjustment TCA events to occur on behalf of the PM Instance due to underflow condition. This status refers to the Adjustment TCA functionality comprising of the following necessary configuration attributes: 1. cienaCesPmIntervalProfileAdjustmentInterval, and 2. cienaCesPmIntervalProfileAdjustmentThreshold or cienaCesPmIntervalProfileAdjustmentThresholdPercentage 3. cienaCesPmIntervalProfileUnderflowThreshold or cienaCesPmIntervalProfileUnderflowThresholdPercentage 4. cienaCesPmIntervalProfileUnderflowCount The Underflow component of the Adjustment TCA requires the regular periodic Adjustment TCA feature to be configured. For this reason, adjustment interval and threshold configuration attributes are necessary before the underflow component is deemed configured (attributes 1 and 2). noProfile indicates there is no interval profile configured for the PM Instance. notConfigured indicates the PM instance is configured with a particular interval profile, however none of the necessary configuration attributes for the Underflow component of the Adjustment TCA feature are configured. partiallyConfigured indicates the PM instance is configured with a particular interval profile and that some, but not all, of the necessary configuration attributes for the Underflow component of the Adjustment TCA feature are configured. configured indicates the PM instance is configured with a particular interval profile and that all of the necessary configuration attributes for the Underflow component of the Adjustment TCA feature are configured.
