On a 1588v2 network, the best master clock algorithm (BMCA) is typically used to dynamically determine a master clock. 1588v2 functions need to be configured according to the device type.
This section describes how to configure static 1588v2 functions. You can specify the master and slave clocks manually, without using the BMC algorithm.
This section describes how to configure UTC time correction. This function helps ensure time signal accuracy on a 1588v2 network and a fix offset between the UTC and TAI time.
A reference interface for deviation measurement can be configured on a device to connect to the reference source (such as the BITS meter or Atom GPS) so that the device and NCE can calculate and automatically compensate for the deviation. In the intelligent clock solution, the reference interface-based deviation measurement mode is generally used when base stations cannot obtain the GPS deviation value.
Lightweight time synchronization implements automatic identification and switching within a device, loosening the requirements on time synchronization precision and simplifying the configuration process.
This chapter provides 1588v2 configuration examples. The configuration roadmap in the examples will help you understand the configuration procedures. Each configuration example includes networking requirements, configuration roadmap, data preparation, configuration procedure, and configuration files.
