Scott,
Make sure if you are using DC power that you are properly grounded. We
ran into a problem very similar to yours, but once the chassis ground
was properly established all the problems went away. We've not had that
problem with AC powered units.

Subject: [USR-TC] Lost-Carriers/Rate Negotiaion
Hello,
I'm having a problem with these tc1000s creating a lot of lost
carriers. Since these modems were installed they have been giving about
14% lost carrier rate. Since we discovered the problem we've been
changing firmwares and trying to get this down but nothing seems to be
working. Currently the tc is loaded with software version 5.3.110. We
put the old pm4's in place and the lost carriers drop to 1-2% maximum,
but with that another problem arises, we've had users calling in and
complaining their connection speeds have been a lot slower. I'm thinking
the pm4 negotiates a more stable speed for the modems than the tc1000's
do and thats what causes the lost carriers in the tc1000 but i don't
know. Is there any way to modify this or does anyone have any other
ideas on what might be causing this.
Thanks,
Scott
