Someone needs to flog the marketing people at Sprint ..
Marketing is marketing.
It's hardly operational tho 
Ehud
p.s. You have "microsoft" and "solutions" together in your .sig.
That generally disqualifies you from slapping sprint's hand.
Since this is drifting, a bit, and it's got "OT" in the subject line, I'd
like to coin a new term for "collapsed SONET rings":
'Two-in-a-trough'
Catchy? Piped through the right marketing folks it could even sound like
something you'd want.

semi-operational: in the event that path inside a SONET ring switches
from active to protect and back, etc...does this generally show up on a
a router as a series of errors, an interface bounce, or not at all?
HTH,
Sam
I'm guessing that the routers won't notice a cutover, it's too fast. Could
someone with more operational experience with SONET confirm this?

Often both. The switch is spec'd at 50 milliseconds. Hardly a twitch
in human voice perception, but a heck of a lot of bad PPP checksums
in machine perception.
Worse, in my miserable experience, the APS would flip back and forth.
It's not supposed to, but it has. I firmly recommend: do not pay for
APS. Put the money toward diverse paths. As usual, Paul Vixie has got
it right!

APS is not intended to be a standalone protection factor. Implemented on routers, it will only protect you up to the first LTE. In most cases, this will be an in-house cross connect.
Don't confuse APS with 1+1 protection.

in the case of you using a circuit (T1, DS3, ATM, ..) which your carrier transports over SONET, the best you'll see is a lost packet or ten.
(the actual switchover time is fast; the amount of data lost is dependent on the distance of the hop -- light 'in motion' is not recoverable).
in the case of you using a POS interface or similar, you may get APS notification, providing the ring that has failed is on the same element as you.
