It detects PTP frames on a (R)(G)MII tap and timestamps PTP event frames based on a Counter Clock and provides them delay compensated to a PTP Software stack (e.g. PTPd, PTP4l, etc…). The Timestamp ...

Based on ITU-T G.8271.1, the IEEE 802.1CM standard specifies fronthaul maximum time alignment errors for different classes of applications that are driving the need for more accurate boundary clocks.
