asterisk users - May 2004 - Dead FXO Module on TDM400P?

Since the irc channel wasn't any help, I will try posting my problem here.
I have two TDM400Ps less than a week old in a PC. All of the FXS ports
work fine, and all of the FXO ports worked fine up until thisafternoon. If
I try to dial in, I get a busy signal, if I try to dial out, all I hear
is a very scratchy, very crackly dialtone. If I swap the first FXO module
with the second on the card, the problem follows the module, not the
physical port on the TDM400P. Any thoughts?

Was planning on deploying this server tomorrow, but now I am worried about
the other three FXO ports crapping out. Has anyone else had reliability
problems with the new FXO card? Or is it too early to tell?

Been using the tdm04b (4 port fxo) for about two weeks with no stability
or reliability issues whatsoever.

I have had substantial echo issues (barely usable) with both the x100p's
and the tdm04b, and have been working with Mark to ID the source. Doesn't
seem to be related to the three pstn lines or the cards, but something is
obviously not right in this rather simple implementation.

You might be bumping against an early card failure. Would suggest calling
digium support to help isolate the problem.
