This attribute indicates whether the LMI is in an error condition or
whether the protocol is behaving normally. This attribute will be set
to errorCondition after enough LMI errors have been detected to
warrant a change in condition. This occurs when n392 of the last
n393 events are in error.
The error condition is lifted when a sufficient number of
consecutive events has occurred without error. This occurs when
n393 consecutive good events take place.
The consequence of an error condition is that all DLCIs on this
interface will become inactive in both directions.
