Total US Flows Total number of upstream service flows, with the number of active service
flows within the parentheses.
Total DS Flows Total number of downstream service flows, with the number of active service
flows within the parentheses.
Total US Data Total data this CM has transmitted on the upstream, in packets and bytes.
Total US Throughput Calculated throughput for this CM on the upstream, if available.
Total DS Data Total data this CM has received on the downstream, in packets and bytes.
Total DS Throughput Calculated throughput for this CM on the downstream, if available.
