MINI-LINK PT 2010 Synchronization Functions
Synchronous Ethernet enables propagation of frequent synchronization over
optical SFPs. The feature provides full SSM handling according to ITU-T
G.8264.
The SEC performs automatic synchronization trail restoration based on
the priority table and the status of the inputs. In the event of failure of all
synchronization source nominees, the SEC enters free running mode using its
own internal clock as source.
The SEC clock is distributed throughout the magazine. In network synchronized
mode all terminated protocol layers interfaces will follow the SEC.
