However, we were seeing tremendous packet loss. After determining the
errors were coming from this end, and testing and replacing everything in
the path, we finally tried moving the router into the telco handoff room
so we could try to eliminate a lot of variables. With a short patch cable,
it worked fine, no packet loss.

So, we made a 200 ft cable to simulate the issue, and hooked it up to the
router while it sat next to the Level3 handoff...major packet loss again.
We tried the other fastethernet interface on the 2651...same problem.

However, if I take that same cable and terminate it into one of our 7200s,
we get zero packet loss.

You mentioned errors, but didn't say what type. Were you actually getting errors (crc/frame/collisions/etc.) or just packets vanishing on the wire?
