SyncE Basic mechanism
The master switch receives the external clock which is a high precision clock. In a synchronous
Ethernet network, Ethernet data is carried over layer 2 whereas the sync timing signals over physical
layer 1. All internal clocks should be synchronized by the external reference clock.
The Ethernet interfaces are designed with an internal clock which is synchronized by the master
external clock. SyncE enables the transport of slave synchronization signals within the entire
network.
The EEC devices are defined as Ethernet Equipment Slave clocks. Ethernet interfaces are also able to
generate their own synchronization clock in case they lose the master reference clock (this situation
is defined as holdover state).
The SyncE Configuration procedure for the R Class series es includes the following display:
SyncE Port Configuration
This section displays and allows configuration of the SyncE configuration of the applicable Ethernet
ports.
