Configuring PTP on a TC

Configuring PTP on a TC

TC Deployment

As shown in Figure 5-11, NodeBs synchronize with the BITS clock and support PTP. Core devices on the bearer network synchronize clocks with the grandmaster clock and send clock signals to downstream devices. Devices functioning as TCs transmit PTP messages between BCs or OCs. In this manner, BCs and OCs can synchronize their clocks. This deployment allows devices that do not have high clock requirements to only transmit PTP messages, ensures synchronization precision, and improves synchronization efficiency.

Pre-configuration Tasks

Before configuring PTP on a TC, complete the following tasks:

  • Set link layer protocol parameters for interfaces to ensure that the link layer protocol status of the interfaces is Up.

  • Ensure that the master clock correctly receives clock and time signals from the BITS device.

Configuration Process

The process of configuring PTP on a TC is as follows.
