Clock Synchronization
Use this procedure to specify the primary, secondary, and tertiary clock source.
A clock source may be a 100D module or a port on an 800 NI-BRI module. See
Feature Reference for more information about the appropriate setting. If the
clock is taken from a 100D module, you can also specify whether the clock is
synchronized to the external endpoint (loop) or to the clock reference source
(local).
NOTE:
This procedure is necessary only if your system includes an 800 NI-BRI module
or more than one 100D module.
