Are you talking about the Line Quality tests? To run those, just log into DSLReports with your account, or make a new one if you don't have one already and then click on Tools. The test is called "Ping/Line Quality Test."
Make sure when you run it that the device, whether a router or a PC is responding to ICMP Ping requests. Otherwise the test won't be very useful. The site should warn you if it will turn out to not be useful.
