Go back out to DSLReports.com and do a Line Packet Loss test. It will
tell you where the problems are occurring, and give you the name of the
hop that is the problem. If it tests ok back to your network, then the
ISP is off the hook.

I do, however, use this test A LOT to go back to the ISP and tell them
"OK, you have a problem with your router named xxxx at address
xxx.xxx.xxx.xxx located in anywhere, usa.

That usually shuts them up.

For about 6 weeks now we have been experiencing really horrible
connectivity
problems.  We have a T1 line, but our network speeds to the Internet
have
been abysmal at best.  I have run some tests using DSLReports.com and
have
found speeds as low as 14 kbps!!!

I've contacted Qwest and they have run some tests on our line from our
office to the ISP.  They have informed me that everything is fine.

So, the problem, as I see it, is either here in our building,
somewhere
(server, router, cables, something), or at the other end.  I've tried
replacing cables, and have done what I could to replace all of the
CAT-5
cables I could fine, but sometimes some cables are connected to things
I
don't understand. For example, we've got something called a T1 CSU/DSU.
 I
don't have the foggiest idea what that is.  And replacing CAT-5 cables
on
that this just makes us loose our Internet connectivity completely.

So, what are things like CSU/DSU?  Or, let's put it differently,
starting at
the ISP who supplies us with T1 access, what "things" are in between
that
and the NIC card in my edge server?
