Total Cells Received – Total number of ATM cells received from the endpoint.
Total Rx Cells Dropped – Total number of ATM cells received by the line card that were
dropped due to policing or congestion.
Total Cell s Sen t – Total number of ATM cells sent to the endpoint.
Total TX Cells Dropped – Total number of ATM cells that would have been sent to the
endpoint that were dropped due to congestion.
Corrected HEC – Number of cells from the customer premises equipment whose
headers were corrected by the line card (Model8335 only).
Uncorrected HEC – Number of cells from the customer premises equipment whose
headers contained multiple errors and were dropped.
OCD Events – Number of Out of Cell Delineation events on the link from the customer
premises equipment.

Total Cells Received – Total number of ATM cells received from the endpoint.
Total Rx Cells Dropped – Total number of ATM cells received by the line card that were
dropped due to policing or congestion.
Total Cell s Sen t – Total number of ATM cells sent to the endpoint.
Total TX Cells Dropped – Total number of ATM cells that would have been sent to the
endpoint or SCM that were dropped due to congestion.
Corrected HEC – Number of cells received whose headers were corrected by the line
card (Model8335 only).
