the previous super frame. 

Near-End: indicates that the sum of the number of tones with a mismatch between 
the expected and measured bit pattern exceeds the threshold in 2 consecutive 
synchronization symbols.  

If the threshold equals the number of active tones (which is the default), an LOF 
indicates that half of the active tones carry the wrong information. Far-End: indicates 
that a near-end loss of frame was detected in the previous super frame. 

LOP: Loss of Power 

Near-End: occurs when the ATU-R power level drops below the nominal power level 
needed for proper operation of the ATU-R. 

Far-End: indicates that a LOP indicator has been received.  

LCD INTER: Loss of Cell Delineation, interleaved latency path. 

LCD FAST: Loss of Cell Delineation, fast latency path. 

LOM: Loss of Margin. 

Near-End: occurs when the measured signal-to-noise ratio (neared) is below the 
required signal-to-noise ratio, as provided by the operator. 

Far-End: occurs when the downstream signal-to-noise margin is below the minimum 
required downstream signal-to-noise margin, as required by the operator. 

The Errors Status screen provides a current status of any error conditions. 

The left column displays results for the upstream signal (received by the ATU-C); the 
right column shows results for the downstream signal (received by the ATU-R). Each 
result is shown for the interleaved and fast latency paths. A circuit will be using one
