Sync Source 2

Software Version: CPC-B Version 4.0 or higher
Address: FF1 8# 4# 1# 3# (0-3)#
Description
Determines the source of clocking for the second sync source, which is used
if the first sync source fails.
If the second sync source is used, the DBS system will attempt to switch back
to the first source based on the value set for the Network Re-Sync Timer (see
FF1 8# 4# 2# 1# 0-25#). If the second source fails and the first source is not
working, the system will switch to the third source.
In most cases, a system with one T1 has the second sync source set to "3"
(Free run). Systems with two T1s normally have the second sync source set
to "2" (T1 of the slave cabinet).
NOTE: One of the three sync sources should be set to "3" (Free run), so that
the T1 can provide its own clocking if the network clock fails.
See the Sync Source 1 address for an introduction to T1 clocking, and a list
of typical sync source settings in single-cabinet and double-cabinet systems.

Notes
Restriction on Duplicate Sync Settings. "Free run" is the only setting that
can be entered for more than one sync source.
Power-Cycling Requirement. For changes to this parameter to take effect,
the system must be turned off, then back on.
