In which way does SyncE propagate the clocking information in synchronous mode over an Ethernet link?
A. It encodes the clock information into IEEE 1588v2 packets
B. It uses the communication channel conveying the clock information that is called SSM
C. It uses dedicated ESMC frames that are sent at regular intervals
D. It uses Layer 2 multicast frames that are sent to 01:00:5E:00:01:01
In order to maintain a logical communication channel in synchronous network connections, Ethernet relies on a channel called the Ethernet Synchronization Messaging Channel (ESMC), which is based on the IEEE 802.3 Organization-Specific Slow Protocol (OSSP) standards. ESMC relays the SSM code that represents the quality level of the Ethernet Equipment Clock (EEC) in a physical layer.
