  • STC Emulated gPTP clock have a difference within 400 milliseconds with NTP clock.
  • Spirent TestCenter 5.07 release or older.


Until now it's not possible to reduce the time difference between STC Emulated gPTP clock and an NTP clock.

The STC gPTP/PTP emulation does not really need the emulation to provide time which is exactly same as the chassis time, so then achieving this will need fundamental changes to ptp/gPTP device emulation.
