Nice when it works. We lost our DS3 for about 18 hours 2 weeks ago. Seventeen OC-48 links were cut. When we asked the about the self-healing, they said, normally it would, but not with the many gone. -- This happens when (if actually implemented as a ring), the Service and Protect are in the same fiber run. Sort of pointless with physical cuts. That is a problem with the user, not the technology. -- They couldn't get permission to dig up the road so that had to patch around, that made the repair take twice as long. And two days later, before they could the patched section buried, a truck took the same 17 out one more time. They were running overhead. Local politics I assume kept them from doing it the right way the first time. --- You must be dealing with a CLEC or an IXC. RBOCs can open emergency permits without prior authorization. They are considered a utility and a vital public service. Competitors are not.
