[time-nuts] Thunderbolt accuracy...??

[Brian Kirby]

I do not think so.  Most telephone company stuff is engineered to last 
20+ years - it takes them a few years to recoup there investments cost 
wise, and the electronics are usually close to mil specs.

Probably what happens, is they engineer a whole new system and all the 
old systems , racks and all go.
