In my area, the cost for about 8 T1s = cost for 1 T3. It's the gray area
(say 6 T1s) in between that had me scratching my head. The price for the
NM-4T1-IMA really isn't bad when compared to the price of the comparable
number of T1 WICs. Thanks for the lead Chuck. Now, I have to figure out
if there are any providers in the area. I know the ones that I deal with
on a regular basis don't offer it....or if they do, they keep it under wraps.
