Thanks, Ken, for reminding me that discussions should go to outages-discussion. This is the last post on this issue until Jason gives us a status update or that it's fixed.

If I should be in a different venue please flame away, but the SNR here for "Outages" lately is sometimes as bad as NANOG.

While you're technically correct, it's not how it's commonly implemented. Well, maybe it's more common than I was aware. =) It's not how regional and state fiber networks in our neck of the woods do it.

Concur. If a customer buys a "ring" they expect a ring. Protection is implied. If they buy a point-to-point, that is a different story. A protected point-to-point might be provisioned on a ring or it might be provisioned with two separate point-to-point circuits. A "SONET ring failure" would require two faults. That said, I have seen cases where both sides of the ring enter a building by the same trench allowing one case of backhoe fade to take out the entire building. _______________________________________________ Outages mailing list Outages@outages.org <https://puck.nether.net/mailman/listinfo/outages> https://puck.nether.net/mailman/listinfo/outages <FONT COLOR=000000> <FONT SIZE=2> ============================================================================ ==================== The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
