A note of personal experience on land sonet: about 5 years ago, the
last time I personally walked a sonet installation, I discovered that
the "ring" that looked so pretty on the engineering diagrams was
actually being laid in a single conduit, without even diverse building
entrances. Seems the contractor was avoiding costs of right of way
acquisition. My report cost the contractor several million in
penalties and redesign, and me much pain. And I've never taken a
sonet contract since. I'm picky. You should be, too.
