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.

• Adding Clock Sources
  When configuring the clock used by the SCC board, you can add clock sources to provide different reference clocks. You can select different clock sources to decide the direction of clock synchronization in the network.
• Setting the Clock Source Priority Table for an NE
  When configuring the clock used by the SCC board, clock sources are arranged in a descending order according to their priorities. The clock source with the highest priority is chosen for synchronization. You can set clock source priorities to adjust the direction of clock synchronization in the network.
