FF1 8# 4# 1# 2# (1-3)# for Sync Source 1
FF1 8# 4# 1# 3# (0-3)# for Sync Source 2
FF1 8# 4# 1# 4# (0-3)# for Sync Source 3
The "Free run" setting is the only setting that can be
entered for more than one sync source. One of the three
sync sources should be set to "Free run", so that the T1 can
provide its own clocking if the network clock fails.
For changes to this parameter to take effect, the system
must be powered down, then powered back up.
0=None (default for Sync Sources 2 and 3)
1=T1 of the master cabinet
2=T1 of the slave cabinet
3=Free run (internal clocking) (default for Sync
Source 1)
In most cases, the sync sources should be set as follows for
these system configurations:
T1 in a Single Cabinet, or T1 in a Master Cabinet:
Sync Source 1 = 1 (T1 of the master cabinet)
Sync Source 2 = 3 (Free run)
Sync Source 3 = 0 (None)
T1 in a Slave Cabinet:
Sync Source 1 = 2 (T1 of the slave cabinet)
Sync Source 2 = 3 (Free run)
Sync Source 3 = 0 (None)
T1s in the Master and Slave Cabinets:
Sync Source 1 = 1 (T1 of the master cabinet)
Sync Source 2 = 2 (T1 of the slave cabinet)
Sync Source 3 = 3 (Free run)
FF1 8# 4# 4# 1# 1# (0 or 1)# for Master Cabinet
FF1 8# 4# 5# 1# 1# (0 or 1)# for Slave Cabinet
Specify the trunk configuration.
0=Analog only
1=T1 and analog trunks
