10.2 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 mobil e 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 includin g 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.
