dpnGateUtpMaximumErroredInterval
dpn Gate Utp Maximum Errored Interval
1.3.6.1.4.1.562.2.4.1.61.2.10.1.1
This attribute specifies the interval time over which the error threshold (as specified by receiveErrorSensitivity) must be continuously exceeded before the Unacknowledged, Utp, or FrAccess component can be degraded. Once the error interval count exceeds the provisioned value, the Unacknowledged, Utp, or FrAccess component issues an alarm indicating that link quality has degraded, and it disables its parent component. The exception to this is a value of zero, the default, which indicates that the mechanism is completely disabled.
