Defining a Clocking Source

Applies to version(s): v2.9.

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
