Typical SyncE Scenario
Figure
7-17
illustrates a typical SyncE Scenario in which:
The local EtherHaul 1200 receives timing information on Eth1 from PRC
(ql 2), and distributes it to all interfaces.
The remote EtherHaul 1200 receives timing information and is locked on
PRC, via Eth0 (RF).
DNU (Do Not use, ql 15) is returned to the source in order to prevent timing
loops.
