A network clock is a necessary component of a TDM network. Synchronizing your system to a clock will ensure that a good condition of your system is maintained. It is recommended that you configure an external clocking source for your system.
To configure a clock:
1- Click Clocking in the navigation panel
2- Click Create New External System Clock Reference
3- Create the new clocking source:
- Enter a name for the clock.
- Select the appropriate hardware adapter
- Select a clock reference type
- Select a clock reference source
Note: In this example, Line Service is selected as the reference type, and a line service is selected as the clocking source.
4- Verify that the System Clock was successfully created message appears, and that the new clocking source appears in the External System Clock Reference List
