IEEE 1588v2
The EtherHaul supports IEEE 1588v2 Transparent Clock (TC). The support is hardware
based. The operator is required to have a software license to activate the capabilities.
The EtherHaul complies with the mobile backhaul specifications for packet
synchronization distribution backhaul architectures for mobile radio access networks.
1588 Transparent Clocks (TCs) used to overcome the 1588 synchronization performance
issue due to packet delay variation over the network. In a wireless link the
compensation of the PDV needs to be done for the entire link including the air interface
and not only per node. The time stamping and the correction field update is HW based.
IEEE 1588 is supported for EH-1200F/FX and EH-600T systems.
