[Warning: Slightly OT]
Actually, here at our corporate headquarters we have redundant fiber
connections to separate telco central offices. The fiber links exit on
opposite sides of the building to frustrate Backhoe Bob in case he tries
to cut through them. These links carry two separate channelized DS-3s
that carry our voice and data circuits. Theoretically, you could bomb
one of the CO and we'd be just fine; both DS-3s would stay up and
running without a hiccup. I hope we never have occasion to test this.
