Displays packet loss (round trip, upstream, and downstream), and upstream
signal to noise ratio (SNR) test results.
Measurement Data
The PACKET LOSS Test contains all of the DOCSIS Packet Loss measurement
data. This measurement data is captured and continuously updated during
the DOCSIS Packet Loss test process. To perform the Packet Loss test,
press the VIEW softkey, use the arrow keys to select Packet
Loss, and press ENTER.
Packets Loss
The packets loss test always uses two paths (upstream and downstream) for
testing.
If the read community string is provided the DSAM displays separate counts
for the upstream and downstream paths as follows:
- Round trip or loop sent packets, lost packets and lost ratio
- Upstream sent packets, lost packets and lost ratio
- Downstream sent packets, lost packets and lost ratio
NOTE:
Upstream Modulation
The upstream modulation portion of the screen displays the upstream SNR.
