I'm going to skip commenting on most of Dean's note
and simply answer one of his questions that nobody
else seems to have touched upon...

Glad to volunteer them. :-)

I would suggest you do so very soon; it will have a major
impact on the way you conceptualize and design your operation.
Keep in mind that a fractional T3 vs a T1 from most reasonably
sized ISP's isn't that much different, typically around $1000/month
for a T1 vs $3000 to $4000/month for a fractional T3 line. With the
T1 lines, you're limited in how much data you can push out, and
you don't really have any upgrade path as far as bandwidth goes.
Also, keep in mind the routing issues involved with 15 T1's
versus 3 T3's are VERY different; unless you have a VERY good
routing guru locally, I wouldn't want to attempt juggling
15 T1's to different AS's as a first effort venture. :-)

Of course! In fact, transit is a separate line item when you
order; all you need to do is not ask for transit, and save the
associated cost. Then all you have access to is our internal
customers and backbone, we don't announce your routes out at
Of course, I should have prefaced this by mentioning that I'm a
network engineer, not a sales person, but since we're the ones
that told sales how to sell this stuff... :)
