Configuring the Time Synchronization Function

This section describes how to configure the time synchronization function.

Usage Scenario

On the IP RAN shown in Figure 1, time synchronization needs to be performed between NodeBs. The Atom GNSS timing solution can be deployed as follows to allow time synchronization: Insert an Atom GNSS module into an ASG so that the Atom GNSS module can synchronize clock signals with the GNSS and the ASG can synchronize clock signals with the Atom GNSS module. Then, configure the time synchronization function to allow transmission of clock signals to other devices on the bearer network. In this manner, network-wide clock synchronization is achieved.

Pre-configuration Tasks

Before configuring the time synchronization function, complete the following tasks:

  • Configure physical parameters of an interface and set the physical status of the interface to Up.

  • Configure the Atom GNSS module to properly process GNSS time signals.
