Clock Synchronization - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Clock Synchronization

Clock Synchronization
Use this procedure to specify the modules that provide primary, secondary,
and tertiary clock synchronization. (Contact your service provider for more
information about the appropriate setting.) You can also specify whether the
clock is synchronized to the external endpoint (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.
