Restore Defaults Restores the factory default settings. See Appendix A, " Default
Configuration " for the default values.
SS Secondary Synchronization—Use this option to specify an alternate source of
timing for synchronization purposes. In the event that 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.
• NET 3: Use this option to synchronize timing to T1 port 3.
• NET 4: Use this option to synchronize timing to T1 port 4.
• INTERNAL: Selects the internal clock as your timing source.
• EXTERNAL: Selects an external clock as your timing source.
TS Tertiary Synchronization—Use this option to specify an alternate source of timing
for synchronization purposes. In the event that the primary and secondary source
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.
• NET 3: Use this option to synchronize timing to T1 port 3.
• NET 4: Use this option to synchronize timing to T1 port 4.
• INTERNAL: Selects the internal clock as your timing source.
• EXTERNAL: Selects an external clock as your timing source.

Auto Restore—Selects which timing source will be used when the primary timing
source fails, restores, and then remains viable for a period of 60 seconds.
For example, if the primary source fails, the secondary source becomes the timing
source. When the primary source is back in service, and the Auto Restore option is
set to Yes, the primary source resumes as the QUAD 2164 module’s timing source.
If the Auto Restore option is set to No, the secondary source remains the timing
source until you manually set the primary source’s Auto Restore option to Yes.
R Receive clock from shelf—Indicates whether the QUAD will receive its timing signal
from the source used by the shelf or derive timing independently of all other
modules. For QUAD/IMUX applications, this option must be set to Yes.
