Configuring Clocks

A high-quality and stable clock signal is essential to the proper transmission of network-wide data. Before configuring services, configure clocks for boards or NEs. Besides, if you want to transmit clock signals in the same way as the service signals are transmitted (so that the clock signals can serve as timing signals for local NEs), you need to configure the protection for clock signals.

• Basic Concepts
  This topic describes the basic concepts related to the WDM clock.
• Configuring NE Clock Sources
  The time source for a WDM NE is determined by the clock used by the SCC board. To synchronize network-wide clocks, modify the clock used by the SCC board according to the specific network configuration. The selection of clock sources determines the directions and termination points for network-wide clock synchronization.
