Clock Synchronization 3
NOTE:NOTE:NOTE:
The following information is for planning clock synchronization in systems
that are not part of a private network. For planning clock synchronization in
a private network configuration, see the
Network Reference
.
Use this procedure to specify the primary, secondary, and tertiary clock source. A
clock source may be either a 100D module or a port on an 800 NI-BRI module.
See the
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 outside endpoint (loop) or to the clock reference source
(local).
NOTE:NOTE:NOTE:
This procedure is necessary only if your system includes an 800 NI-BRI
module or more than one 100D module.
