<FONT SIZE="2">Interesting observation #2: I think I know how to make the tdm card die. I have a pc behind one of the Ethernet cards on the server. When I do a download off the net, the tdm card dies. Keep in mind when I'm doing a download two Ethernet interfaces are working, the one to which the pc is connected and the one connected to my cable modem. I've just tried another download - I'm almost 100 percent sure I can make the card die this way.</FONT><BR>

It seems somewhat obvious-- I'll bet, if you look at (via 'cat /proc/interrupts') the interrupts, you'll<BR>
see that the tdm shares an interrupt line with one of the ethernet cards. All it takes for something like<BR>
this to happen, is for the ethernet card to take longer than 1/8000th second to handle it's interrupt.<BR>
<BR>
Solution? Work with the plug & play BIOS settings, and maybe move boards around in the slots,<BR>
so you can the tdm on an interrupt line all by itself. Maybe, make another machine the <BR>
network gateway, use your asterisk machine for VOIP phones only. You'll have to experiment.<BR>
