PS
Primary Synchronization: Choose one of the following as your primary source
for clock synchronization.
Net 1: Use this option to synchronize timing to T1 Port 1.
Net 2: Use this option to synchronize timing to T1 Port 2.
External: Use this option if you want to use an external clock as your timing
source.
Internal: Use this option if you want to use the internal clock as your timing
source.
Data 1: Use this option to synchronize timing to the Data Port 1 TT signal.
Data 2: Use this option to synchronize timing to the Data Port 2 TT signal.
1) NET 1
2) NET 2
3) EXTERNAL
4) INTERNAL
5) DATA 1
6) DATA 2
SS
Secondary Synchronization: Use this option to specify an alternate source of
timing for synchronization. If the primary source is unavailable, this source
will be used.
Net 1: Use this option to synchronize timing to T1 Port 1.
Net 2: Use this option to synchronize timing to T1 Port 2.
External: Use this option if you want to use an external clock as your timing
source.
Internal: Use this option if you want to use the internal clock as your timing
source.
Data 1: Use this option to synchronize timing to the Data Port 1 TT signal.
Data 2: Use this option to synchronize timing to the Data Port 2 TT signal.

Tertiary Synchronization: Use this option to specify an alternate source of
timing for synchronization. If the primary and secondary sources are
unavailable, this source will be used.
Net 1: Use this option to synchronize timing to T1 Port 1.
Net 2: Use this option to synchronize timing to T1 Port 2.
External: Use this option if you want to use an external clock as your timing
source.
Internal: Use this option if you want to use the internal clock as your timing
source.
Data 1: Use this option to synchronize timing to the Data Port 1 TT signal.
Data 2: Use this option to synchronize timing to the Data Port 2 TT signal.

Primary Auto Restore: Indicate Yes to resynchronize to your clock preference
automatically if the clock in the node fails. Otherwise, choose No. Setting up
auto restore returns timing to a higher priority source after a failure. If you
have not set up auto restore to the primary source, but you have indicated a
secondary source, after rebooting the module uses the latter source to
restore timing to the module or shelf.
Yes or No

SA
Secondary Auto Restore: Indicate Yes to resynchronize to your clock
preference automatically if the clock in the node fails. Otherwise, choose No.
Specifying a secondary source for clocking is useful if power fails and causes
failure of the primary automatic restore source. Restoring from a secondary
source may take up to 60 seconds.
Yes or No
