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!).
