To perform a basic ADSL link test
– Connect to the line and allow the unit to train on the line.
If the unit achieves sync at the desired data rates, noise
margins, and attenuation, the ADSL link is good.
Once connected to the line, the HST-3000 gathers statistics
for the line. These statistics are used to determine the line
quality.
