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!).
