There's a difference between folding a ring or pushing out a spoke to feed a few customers and providing connectivity to a town. I think building a SONET ring, or any kind of redundancy, has more to do with a rural telco's commitment to it's customers than the bottom line. Remember, the building of plant contributes to the cost study, so it may end up having zero cost in the end.

Anytime you talk about "rural" I'm impressed with 7 hours, however -- isn't SONET supposed to make this better?
Sure, if: 1. the protect path is configured and enabled 2. both the working and protect paths don't run through the same conduit/duct/buffer
I am continually amazed at how often this is the case. I realize that it's expensive to run these lines but when you put your working and protect in the same cable or different cables in the same trench (not even a trench a few feet apart, but the same trench and same innerduct), you have to EXPECT that you're gonna have angry customers. And yet when telco folks learn that this has occured, they often fein being as surprised as the customers. Truely amazing. --- Wayne Bouchard web@typo.org Network Dude http://www.typo.org/~web/
