• Adaptive clock recovery with or without the node timing: based on the average
rate at which the packets (fragments) arrive at Rx site (Adaptive: simpler network, but
performances depends on the PDV (Packet Delay Variation) in the Network. Always
used when the reference clock isn’t distributed on the whole network). This method
can be selected for each E1 stream for TDM2Eth only.
3.10.15.1.1 — Differential clock recovery
A common reference clock is available at both Ends.
The IWF system, at Rx side, generates the output clock based on RTP TimeStamps which
are sent together with each Fragments.
3.10.15.1.2 — Adaptive clock recovery
Note: In meshed networks (rings) do not close the synchronization configuration.
