Sync Source 1
Software Version: CPC-B Version 4.0 or higher
Address:
FF1 8# 4# 1# 2# (1-3)#
Description
The Sync Card (installed on the CPC-B) provides a method of synchronizing
the DBS with the public network. This address determines the first clocking
source for network synchronization (internal clocking by default).
If the first clocking source fails, the system will switch to the second source.
The system will attempt to go back to the first source based on the Network
Re-Sync Timer setting (see FF1 8# 4# 2# 1# 0-25#).
The system considers a clock source to have failed when the Slip Counter is
exceeded within a 24-hour period. See FF1 8# 4# 4/5# 3# 2# (0-9000)# for
instructions on setting the Slip Counter.
Typically, Sync Source 1 is T1 of the master cabinet. See
“Notes”
below for
a list of typical sync source settings for single- and double-cabinet systems.
