While talking with one of the sangoma folks very recently, he was
rather emphatic the pci bus was designed to "share" interrupts. I was
a little concerned as a test server had the wanpipe driver sharing an
interrupt with libata and uhc1_hcd. His comment was "that's the way
its suppose to work, sharing interrupts as needed". I've not had any
recognizable issues with the A200D card at all, and faxing via a A200D
fxs port to a A200D fxo (pstn) port functions 100% reliably.
What that would suggest is the TDM400 pci firmware (whether on card
logic or whatever) is the source of at least part of the TDM400 shared
interrupt issue. I don't have any digium T1/E1 cards laying around,
but if memory serves correctly, the T1/E1 cards do not use the same
pci controller chip. That would suggest the T1/E1 cards are less of an
issue then with the TDM400 card.
That's good to know, but considering the response from Digium on the
TDM400 ( try another motherboard) when there didn't seem to even be an
int. sharing issue, the card just couldn't be seen at all , and the
support I received from Sangoma on a recent FXS issue that was resolved
within a few days, I would tend to go with Sangoma for the T1 card, if
and when I have the need.
