‘SysParams’ Table
Parameters
These are the parameters that are documented:
PANEL_PRESET_TIMEOUT Delay, in seconds, before an idle control panel blanks out its preset
source name. Typical values are 30 seconds.
SALVO_BTN_DEBOUNCE and
SALVO_BTN_TIMEOUT These two values are used together to define salvo button behavior
on an NV9602. Ordinarily, salvo buttons on an NV9602 cause the
immediate execution of a salvo. If that behavior is not desired, the
above values can be set to make salvo execution a two-press opera-
tion. When a salvo button is pressed the first time, it will light.
The “SALVO_BTN_DEBOUNCE” value is the time, in milliseconds, that
must elapse between the first and second button press. This prevents
an accidental ‘double-tap” firing the salvo.
The “SALVO_BTN_TIMEOUT” value is the amount of time, in half sec-
onds, that the user has after the first press to press the button again.
Once this time elapsed, the salvo button will dim.
Currently these two values do not appear in the ‘SysParams’ table.
However, there is a default value of 30 (ms, and sec., respectively) for
these two values, which means two presses are needed. To override
these values, place them both in the ‘SysParams’ table with a value of
0. You can also change the values if you like.
PERSIST_VIRTUAL_XPT This means “persistent virtual crosspoints.” If this value is set to 1, the
NV9000 will retain the state of virtual crosspoints through a restart,
reboot, or power-cycle of the control system.
On redundant systems, the virtual crosspoint information is not
shared between the system controllers, so the system controller on
which a router having virtual crosspoints is active at startup will be
the system controller that sets persistent virtual crosspoint informa-
tion.
FAILOVER_SALVO_1_TO_2 and
FAILOVER_SALVO_2_TO_1 The NV9000 software can execute a salvo when a failover occurs from
one system controller to another. The FAILOVER_SALVO_1_TO_2
value must be the database ID of the salvo that will execute on con-
troller 2 when it goes active.
Similarly, the FAILOVER_SALVO_2_TO_1 value must be the database
ID of the salvo that will execute on controller 1 when it goes active.
LEVEL_DO_SIMPLE_TAKE This parameter allows the NV9000 software to interpret a physical
level as if it were a virtual representation of the routing system. It will
always switch devices configured on that physical level using an all-
level take.
This feature allows NV9000 clients a greatly simplified interface into a
complex routing system. The value in the ‘SysPArams’ table for this
parameter is a comma-delimited list of database IDs for physical lev-
els that should be switched as all-level.
AUTO_FREESRC If this parameter’s value is set to 1, the NV9000 software automatically
routes the configured free source to the input of a tieline when that
tieline is no longer in use. Other values for this parameter are no-ops,
causing no special behavior.
The free source is that configured for the level set of the destination
of the tieline route.
NV_LAST_WRITE_TIME The last time (and date) the configuration was written to a system
controller.
