asterisk users - Jan 2006 - Recommend Fax Hardware for T1 PRI

I have posted this to the Asterisk Forums, but
got no response yet.  Sorry if you are reading
this for the second time.

What fax hardware do I need for a T1? Ideally, I
will switch my T1 to a digital PRI (not CAS I'm
told, which is not as good) coming into the
building. My CLEC said I can do this switch no
problem. I have an analog T1 coming in now.
>From the Asterisk box, I will connect IP phones,
but I still need 2 analog ports for fax machines.
I don't want to do any VOIP fax like T.38 or
anything. I just want to use a standard fax
machine so I can send outbound faxes reliably and
so I don't confuse my users and more than they
will be with a swtich from analog old AT&T Merlin
system to IP PBX.

I assume I need a TDM400P (TDM20B flavor for 2
analog stations), but I am not sure. Down the
line I may buy something like FaxFinder or try to
figure out Hylafax or some other solution if this
meets our needs, but I like the flexibility of
outbound faxing of a paper document. You just
can't send a paper document as easily with all
electronic faxing.

Thanks in advance!

You can buy ATA (analog terminal adapter) or the card you mention. Bouth 
of them shuld work just fine.

Wonderful advice. Both of these solutions actually fail for most people.

You could use a 2 span T1 card from Digium and plug one span into a
channel bank, and have FXS ports on the CB for the fax machines. With
the latest firmwares from Digium these streams are bridged internaly
on the card, and don't even come on to the PCI bus.

Any cheaper, equally reliable way to do this? 
Looks like a base Rhino channel bank with a 4
port FXS card will run me about $900.

I can vouch this works very well. I do so with a
4port card and 1 or  
2 Adits. All the traffic stays TDM and just works.

Although I am presently exploring using 24port
FXS devices peering  
with T1 gateway devices to replace this. Much
more flexibility.

Digium card worked for me.
