To take advantage of this redundancy, the entrance facilities to your
building must not be part of a "collapsed ring" where both fiber pairs
are in the same conduit/bundle.

Quite often this is not done right.  If it requires two backhoes to take
it down, it requires two backhoes to build it.  In other words, for SONET
redundancy to be of value to you there need to be two physically separate
fiber feeds to your location that remain physically separate throughout
the ring.
