Adjacent cities is not what the long haul providers generally do.=20

My clients want Chicago Equinix to Frankfurt Interxion or Chicago =
Equinix to 60 Hudson. Not Pittsburgh to Cleveland.=20

The capex for those services is many hundreds of thousands of dollars.=20

Consider all cards required to a provide a protected 10 gig wave service =
when you have substantial DWDM infrastructure. Not only regen huts, but =
the POPs in between the desired end points. We have lots of regen huts =
and POPs in between Chicago and NYC.=20

You can't built protection with only four 10 gig wave cards on most =
routes.=20

To take the point further, if you are building a TransAtlantic circuit, =
you're going to need cards at every landing station. If you have two =
landing stations on both sides of the Atlantic, then you are talking =
eight cards. Hmmm  ...

Every span has to be protected.=20

And it doesn't make sense usually to be put in separate platforms to =
reduce the capex involved in those rings.=20

That's funny, because our company is a (very small) LEC and a member of =
a
(small) regional network, and we've been asked by a larger consortium to
give them protected 10-Gig waves between two cities.  It's not been a
problem to find DWDM vendors that can do that.

That service is probably very expensive. =20

There is no known way to provide cheap 10 wave protection. Not carrier
grade. Protected 10 GigE service (LAN PHY 10 GigE) will tolerate a very =
high
BER before switching. And the cost of switching STM64 is very high as =
well.=20

Bottom line is that it will cost more than two diversely routed 10 gig
waves.=20

There is no real market for protected 10 gig waves. Occasionally a bank =
will
request the service, but backoff as soon as they see the price tag.=20

"Hopefully none of these customers had service and protect ckts that =
went
down... I would be pissed as a ceo if that happen to my company.  =
Hopefully
level3's new service offering is 100@percent redundant as stated

The new service offerings include: - Protected Wavelengths: Level 3 now
provides automatic protection-switching to a dedicated diversely routed
wavelength in the event of a network failure. The protection switch, =
fully
automated and managed by Level 3, happens at switching speeds =
approaching
SONET restoration times. The single interface to the customer requires =
no
additional capital cost for customer optical ports, and the diverse
restoration path is fixed and fully known to the customer. These =
features
allow customers to achieve fast restoration with predictable performance =
in
their network without adding significant cost and routing complexity. -"
