Peter,
You'll want to use the Frameline card. It has built in HDLC resources
necessary to bring up all 8 nailed T1's. You can do fractional T's as well,
but no dialup termination on these T's. Using the 8T1 card with HDLC cards
is not a good idea. The algorhythm in which TNT's assign HDLC resources is
inefficient, and causes connections to mysteriously drop if any switched
calls contend for those resources. You'll also need an HDLC card for about
3-4 nailed T's, depending on your system. Which makes it very expensive
too.

Let me know if you need more details.

Cheers,
Scott Kozicki
