Carrier Recommendations

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.)
