A few thoughts that relate to your question ... We do a couple of things to
extend our IP backbone along the lines of what you're asking ... in
addition to the LEC and/or "dry pairs" options, you might also look to
extend your reach via use of private or consortia fiber or radio
networks. We are fortunate to be able to reach many of our non-campus
locations via our Institutional Network (or INet, loosely defined as fiber
network provisioned by our State franchised cable television companies as a
part of their franchise agreement). For example, in order to provide some
inter-campus links, and connectivity to public-sector facilities, we ride
the INet fiber network and provide high-capacity IP connectivity between
campus backbones. In some cases, we will also provision radio links where
there are severe geographic constraints to connect specific locations,
e.g., islands (funny how those LEC trucks just have a hard time driving on
water ;-). In addition to the "traditional" licensed microwave shots,
there are some interesting alternatives at higher frequencies providing
much larger payload capabilities, along with smaller antenna profiles (of
course, with more limited range).
With respect to commercially available broadband solutions, you should be
careful to understand exactly what you're getting from
point-to-point-to-point. For example, LEC xDSL solutions are notorious for
gaming the DSLAM configuration and backhaul link (the link from the DSLAM
to your POP) interface ... it's the traditional ISP "profitability" model.
Hope that's helpful.
