We run tests from our switch, I guess it is good when you are the telco also
:). This gives us the ability to look for shorts, and high levels of noise.
The main problem I find with lines that cannot connect are there is a short
some in the customers house.

I have found that our problems break down this way:
80% of the time, the connection problems we have are people with POS modems.
The other 20% are line related.
of that 20%, 30% have to do with distance(we are rural, have some people
40K+ feet from their nearest switch).
the rest of the time they have a short somewhere in their house. This
causes even good modems to not negotiate proper connections.

What we have them do is plug into their de-marc, and unplug their house.
This tests the wiring from the Telco to them. If the problem keeps
happening, and they don't have a POS modem, we generally cut their pair and
remove any bridge taps on their line. If it is a POS, we try to help them
as much as we can, but sometimes tell them it is out of our hands, we have
done everything we can.

Unfortunately we are running over a network that was designed voice, not
data. Most Telco's will only guarantee 9600 bps, so their is not much that
you can do.
