NOTE
When using a customer's CM MAC address, the config file name
may indicate the grade of service the customer gets. A file name
containing “default” generally means that the CM MAC address
used for the test is not provisioned.

NOTE
Since Throughput can only be measured after the meter has suc-
cessfully ranged and registered with the CMTS, Throughput results
are not available if Ranging Only is set in the DOCSIS Configura-
tion field (
“Configuring DSAM for DOCSIS Tests” on page 205
) or if
registration with the CMTS failed.
