About This Chapter
Clock synchronization is used to keep differences in clock frequency and phase among network
elements within a tolerable range. Effective clock synchronization improves the transmission
performance of a network.
9.1 Introduction of Clock Synchronization Configuration
Clock synchronization ensures that digital pulse signals are sent and received in a specific
timeslot.
9.2 Setting Basic Configurations for Clock Synchronization
This section describes how to set basic configurations for clock synchronization.
9.3 Configuring an External BITS Clock Source
You can run commands on the routerto configure the device to trace different types of external
BITS clock sources.
9.4 Configuring a Clock Reference Source Manually or Forcibly
This section describes how to manually or forcibly configure a clock reference source.
9.5 Configuring Clock Protection Switching Based on SSM Levels
The higher its SSM level, the more accurate a clock is. By default, a clock board uses the most
accurate clock source available.
9.6 Configuring Clock Protection Switching Based on Priorities
If clock sources are configured with different priorities, then the clock source with the second
highest priority becomes effective immediately after the clock source with the highest priority
fails.
9.7 Configuring Ethernet Clock Synchronization
Ethernet clock synchronization implements clock synchronization among devices on an IP
bearer network.
9.8 Configuration Examples of Clock Synchronization
This section provides examples for configuring clock protection switching and for configuring
Ethernet clock synchronization.
