I tend to agree, fiber rings when built out correctly have subtending rings to handle redundancy with extremely low delay times 50ms at worse -Henry "Douglas S.

Not having seen the entire cut, I would have to imagin the entire bundle
was
cut and the poor splicers had their hands full.
From experience, I can say that its quite easy to sabatoge a fiber run.
The perfect example - a few years ago when I was a network admin, the whole NOC where the bulk of our T1s were went out suddenly one morning. We discovered that less then a block away a fiber seeking backhoe dug right through the fibers - both the primary *and* secondary fibers - because Verizon burried them both in the same trench rather then run them separate routes. So, the supposed redundancy went right out the window. The phone companies really aren't helping the situation one bit by doing stuff like this. -------------------------- Brian Bruns The Summit Open Source Development Group Open Solutions For A Closed World / Anti-Spam Resources http://www.sosdg.org The AHBL - http://www.ahbl.org
