Configuring PTP on an OC

Configuring PTP on an OC

OC Deployment

As shown in Figure 5-9, when two devices transmit wireless data on the IP bearer network, low-delay transmission must be guaranteed for real-time wireless services. As OCs, the two devices transmit clock information through PTP messages to ensure clock synchronization between them. OCs can provide a high-precision clock source for devices in a PTP domain using the Building Integrated Timing Supply (BITS) system.

Pre-configuration Tasks

Before configuring PTP on an OC, complete the following tasks:

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

  • Configure a grandmaster clock to correctly obtain clock and time signals from the BITS device.

Configuration Process

The process of configuring PTP on an OC is as follows.
