asterisk users - Aug 2006 - 3COM NBX and Digium Cards...

I have a customer that has returned two cards, a TE210P and a TE110P
because they are no longer working.  Both cards were connected to an
3COM NBX system but not to the same one.  On the TE210P only the port
that was connected to the NBX failed, the other works perfectly.  

	The cards are on separate sites, one is on an IBM server, the other one
in a Dell.  The only thing in common is that both cards were connected
to a NBX.  Both Asterisk systems worked fine for about two weeks and
suddenly stopped working.  Does anyone have any idea what could be
causing the failures?  Is the NBX capable of doing something that can
damage the Digium cards?

I have a TE205P card connected to a 3COM NBX system
with no problems for the 
past 6 months.
But as it is used for testing and demos only the
amount of traffic is 
typically around 10 calls per day, and sometimes no
calls are exchanged on 
the line between the Digium TE205P and the 3COM NBXfor
days at a time.
