When a ping test starts, response results begin scrolling upward in
the response box (upper right corner of the screen). The most
recent ping result is displayed at the bottom of the list.
The status box (lower right corner of the screen) displays the reply
statistics, including:
– Number of pings sent
– Average return time
– Number of pings lost
– Ratio of lost to sent pings
Ping data is continuously updated.
NOTE
Since ping time can only be measured after the meter has success-
fully ranged and registered with the CMTS, ping results are not
available if Ranging Only is set in the DOCSIS Configuration field
(“Configuring DSAM for DOCSIS Tests” on page 205) or if the
DSAM fails to register with the CMTS.
