I think you have the wrong idea on this T-1 thing. If a fiber cut is taking out your T-1's, as Mr. Mauch was saying. Then you would have a SONET entrance facility from the LEC into your building. Having the LEC build the entrance as a bidirectional ring with diverse physical entry points into the building is the way to go. The only way a T-1 can be dropped due to a fiber cut is if the build is Linear or the transport provider built a single physical entry point (which is shady to say the least!).

my biggest concerns would be the following:
1) Fiber Cuts that take out your t1's 2) Power Outages 3) Router Failures
even simpler than that. you need to make sure your ds1 is coming from differnt physical entry points of the facility from different CO's. one drunk running into the telephone pole outside your place, or a flood in the utilities under the streets can wipe you out if there aren't multiple paths.
an absolute fallback would then be a uhf/microwave link to another facility which now a days can do 10Mb/s for not too much $$.
