Jimmy,
ISDN isn't available. At one time telco Engineering thought they could
do it if I gave them 15-thousand bucks. Then, decided they didn't have
the resources even for that dough. But, said a T1 was destined for a
major phone-computer using government org 5 miles further north and that
the T1 would run within 1.25 miles of my place. Whenever that happened,
a fractional T1 would be available. Maybe. That project is 1-yr behind
schedule at last word.

Liam,
I used ISDN when I lived in the boondocks. Dual channel is very solid
and runs 128k all day and all night with no problems. Actually single
channel would have been fine. Also used DTN satellite but that doesn't
sound like your kind of deal.
