WebJan 8, 2014 · The Cisco 2-Port Gigabit Synchronous Ethernet SPA also provides additional services, such as time and frequency distribution across Ethernet networks using the following technologies: Synchronous Ethernet (SyncE): Defined by ITU-T standards such as G.8261, G.8262, G.8264, and G.781, this technology uses the PHY Ethernet layer to … WebIf the port is a fixed copper Ethernet port and in 1000BASE-T mode of operation, there is a dependency on the 802.3 link timing for the Synchronous Ethernet functionality (see ITU-T G.8262). The 802.3 link timing states must align with the wanted direction of Synchronous Ethernet timing flow.

Synchronous Ethernet, also referred as SyncE, is an ITU-T standard for computer networking that facilitates the transference of clock signals over the Ethernet physical layer. This signal can then be made traceable to an external clock. See more The aim of Synchronous Ethernet is to provide a synchronization signal to those network resources that may eventually require such a type of signal. The Synchronous Ethernet signal transmitted over the Ethernet … See more The synchronization and transport networks are partially mixed, since some NEs both transmit data and distribute clock signals to other NEs.
