If this is for redundancy, also keep in mind that most 'cuts' occur
in the last mile. Unless you are in a major facility with engineered
entrance/egress diversity a failure will result in ALL terrestrial
links failing. This is a very string argument for a limited
bandwidth satellite or EVDO backup link. (Which one depends on many
other factors.)
