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. WSimpson () UMich edu Key fingerprint = 17 40 5E 67 15 6F 31 26 DD 0D B9 9B 6A 15 2C 32
