I like the thinking; the challenge is often where in the world you are,
and how much competition there is. Here in Ontario, T1's were generally
priced such that fractional T1s hardly saved anything. There is more
competition now, so prices are changing, but I still can't see frac T1
service competing with such a small number of analog circuits. I know
there are places where such a thing could be had very competitively, so
your advice is still good.

Agreed.

Thanks kindly for the reply.
