Precision Time Protocol (PTP)

  • Assisted partial timing support over PTP (ACX7024)—Assisted partial timing support (APTS) is a Global Navigation Satellite System (GNSS) backed by Precision Time Protocol (PTP), delivering accurate timing and synchronization in mobile backhaul networks.

    APTS enhances network synchronization by combining local GNSS timing with PTP-based calibration from a core clock. This ensures accurate timekeeping even during GNSS outages, making it ideal for edge deployments in mobile and distributed networks.

    [See Assisted Partial Timing Support on Routing Platforms.]

  • Support for configurable hold over time interval (ACX7024)—In an assisted partial timing support (APTS) setup, when both GNSS and the PTP time references are lost or inactive, the internal clock oscillator can provide synchronization. You can now set the required duration for synchronization with the newly introduced command set protocols ptp holdover-in-spec-duration on ACX7024. This functionality is enabled by default with a duration of 240 minutes.
