This attribute counts the number of one second intervals in which at
least 30 percent of the IMA Control Protocol (ICP) cells were
counted as ICP violations or at least one link defect (physical layer,
LIF and LODS defects) was detected. This attribute will not
increment during UAS (Unavailable Second) conditions.
This attribute will always have a value of 0 if the protocol for the
IMA group is proprietary.
