I enthusiastically agree that a loopback plug should be part of the
standard toolkit if you have T1 or PRI services. It has made my job a lot
easier to be able to slap a hard loop on the end of all the copper and
have the telco run their tests. If they can run clean that way, we can be
reasonably sure that the wires, repeaters, smartjacks, etc. are OK. This
is great for verifying that your inside wiring is OK all the way to the
back of your PM3 or CSU/DSU. The testers really like it when I mention
that I can put a hard loop on the circuit for them.

Kyle, I really appreciate your input on this list. One of the biggest
problems with the stuff all of us are doing these days is the lack of
communication between us as users of the services (T1, PRI, etc.) and the
telco technical people. Now, if only someone from Southwestern Bell were
on this list?

You can take a jack and short the leads or take an RJ45 connector and do
the following.
