Clock Synchronization

Use this procedure to specify the modules that provide primary, secondary,
and tertiary clock synchronization. In addition, you can specify whether the
clock is synchronized to the external end point (loop) or to the clock reference
source (local). This procedure is also used to activate or deactivate the clock.
NOTE:
This procedure is necessary only if your system includes more than one
100D module.
