asterisk users - Jun 2005 - Interfacing to an IAD

I'm considering switching my incoming phones lines from standard analog 
to a T-1 service from XO communications. They propose to bring in an 
"IAD" which has 12 lines of voice and 768k of internet bandwidth as
part
of a package deal. Since I want to keep the voice traffic in the digital 
domain the equipment they're proposing is a "Lucent Digital Vina 
Integrator" IAD with a digital TC card. I've searched the web to find 
any sort of info on how I can connect this IAD to my Asterisk box 
without success. What I find in general is that this kind of IAD can 
either provide analog voice output (POTS) or "digital T-1" output. I 
presume the latter is what they're providing.

Is a "digital T-1" from an IAD the same kind of interface as a PRI
T-1?
Would something like a Digium TE-110P handle this interface? Does anyone 
out there have experience with a Vina IAD with digital voice circuit output?

Thanks for any assistance.

I have had experience with both the Vina and with XO.  If you ask for
it, you should be able to get an Adtran 600 series on the circuit.  I
never had any success with the Vina and it really is not a piece of
equipment I would bet the farm on.  They may have improved but I would
still just as fo ran AdTran since it definitely has a T1 interface that
works.

Cheers,
Wiley
