They are moving to using IEEE 1588 for site synchronization. I guess you 
could consider it "something like NTP on steroids." It requires hardware 
assist to achieve the accuracy needed. No need for an Rb for holdover. 
Timing is carried with the same packets which carry the voice traffic. 
If the packets aren't getting through, then you're dead anyway.
