Sync Source 1
The Sync Card (installed on the CPC-EX) provides a method of syn-
chronizing the DBS with the public network. This parameter deter-
mines the first clocking source for network synchronization. If the
first source fails, the system will switch to the second source. The
system will attempt to go back to the first source based on the value
entered under "Network Re-sync Timer" (page 4-7).
The system considers a clock source to have failed when the slip
rate error counter is exceeded within a 24-hour period. (See page 4-
23 for instructions on setting the slip rate error counter.)
In most cases, the 1st sync source is set to "1." See page 3-5 for a list
of typical sync source settings for single and double-cabinet sys-
tems.
Notes:
1. The "free run" setting is the only setting that can be entered for
more than one sync source.
2. For changes to this parameter to take effect, the system must be
powered down, then back up again.
