Command Description Options

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.

1) NET 1

2) NET 2

3) EXTERNAL

4) INTERNAL

5) DATA 1

6) DATA 2

TS 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.

1) NET 1

PA Primary Auto Restore: Indicate

Yes

to resynchronize to your clock preference

automatically if the clock in the node fails. Otherwise, choose

. 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

(Y/N)

SA Secondary Auto Restore: Indicate

Yes

to resynchronize to your clock

preference automatically if the clock in the node fails. Otherwise, choose

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
