The only issue I have with that is there are several people with digium
T1 and TDM cards in their systems, and its always the TDM that goes out
to lunch; not the T1. No doubt there are less then desirable mobos around (and probably lots of them), but that doesn't explain why stability
of the TDM's very different from a T100P (both with Intel 537 chips).
You know, this is sort of a crazy guess, but I think the power on the telephone line has a lot to do with the flakiness of these cards.
I've seen something with the X101P that lead me to think so: I have two cards and two lines. I also own a small UPS that happend to have a jack for a phone line, to act as a "power cleaner" and I've put the line that goes to one of these cards there.
Now, in two different occasions, during a power out the UPS signaled the server which shutdown gracefully and when the power was back on , the card whose line went through the UPS was in a "Red Alert" state.
Only taking out the line from the UPS and putting it directly into the telco socket a couple of time cleared this alaram (no, even rebooting did not help).
After these two inceidents I simply kept the line directly to the socket (like the second card) and we had several power outages since (don't ask) and this did not happen.
So my guess is - what makes the FXO/FXS more sensative then the PRI cards is the power on the line. Or not. Did I mention it's crazy guess? :-)
