A Registration Request, DSA Request or DSC Request will be denied due to temporary resource limitations if it would result in an active or admitted service flow whose mininum reserved bandwidth would cause this threshold to be exceeded on the downstream channel. If the percentage is set to 0, the default value will be used and reading this object must return the the default L3 threshold. If a set operation tries to change the value of an existing instance of this object to any value that is lower than cadIfDownChannelCACL1Threshold or lower than cadIfDownChannelCACL2Threshold on the same row, then an 'inconsistentValue' error must be returned.
