Configuring the QPRI 2921 Via the NCM 2000 Craft Interface
Verilink QPRI 2921 3-11
For ISDN, you must provide shelf timing derived from the ISDN PRI
span. All cards with dial-backup must use shelf timing. Set the
secondary timing source for the second ISDN port, if used
(otherwise set it to internal). The following options are valid if you
specified “No” to “Receive Clock from Shelf”:

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 Net Port 1.
Net 2: Use this option to synchronize timing to Net 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.
Net 3: Use this option to synchronize timing to the Net Port 3 signal.
Net 4: Use this option to synchronize timing to the Net Port 4 signal.
1) NET 1
2) NET 2
3) EXTERNAL
4) INTERNAL
5) NET 3
6) NET 4
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 Net Port 1.
Net 2: Use this option to synchronize timing to Net 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.
Net 3: Use this option to synchronize timing to the Net Port 3 signal.
Net 4: Use this option to synchronize timing to the Net Port 4 signal.
1) NET 1
2) NET 2
3) EXTERNAL
4) INTERNAL
5) NET 3
6) NET 4
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 Net Port 1.
Net 2: Use this option to synchronize timing to Net 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.
Net 3: Use this option to synchronize timing to the Net Port 3 signal.
Net 4: Use this option to synchronize timing to the Net Port 4 signal.
1) NET 1
2) NET 2
3) EXTERNAL
4) INTERNAL
5) NET 3
6) NET 4
PA 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
(Y/N)
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
