Any analog modem (fax or pc) is going to be limited to 9600 baud or slower,
and will only achieve that speed if g711 is used through the entire path
(including asterisk). If a modem call comes in one T1 (or PRI) and goes
out another, asterisk is still handling the pcm packets. The packets don't
magically jump across T1 cards (or T1 ports on the same card).
Rich,
I'm not quite sure what you're concluding here, but we routinely fax hylafax->asterisk->hylafax and hylafax->asterisk->PSTN in a variety of analog and digital configurations, with and without channel banks at speeds up to 33,600.
There's no reason Lee's outline:
T1 --> TE405P(1) --> Asterisk --> TE405P(2) --> Patton 2977 --> HylaFAX
won't work perfectly well. Granted the Patton 2997 is limited to 14,400 maximum, but with other T1 cards such as Eicon Diva Server and Brooktrout TR1034 there's no problem negotiating and sustaining V.34 speeds (14,400 ->33,600).

Darren,
From what's been said, it looks like in order to use the existing PRIchannels, I either have to use this kind of setup or an analog adapter? It's good to know that this setup will indeed work. However, I don't think that I'm going to get approval to purchase a $3,000 fax card and a $1,500 T1 card.
So I guess I'm stuck with the analog adapters....
Thanks for your help.
Brian
