Yes, you are right about that.
It most cases the ISP will give you a T3 with a bandwidth cap on it. The
ideal behind it
was that, since it cost the same to layout the lines you might as well get a
cap T3 then a T2.
That way you don't have to layout another line when you need more bandwidth.
{just {re|un}cap it instead)

One of the companies I used to work for had an OC12 layout for that reason
and they were only using T3.
