Operation
Operating Concepts
Categories that include both source and destinations appear in both source mode and destina-
tion mode.
Destination Protect
This button is a toggle that sets or clears a protect on the current destination device. The protect
can be removed at the panel that originally set the protect, at any panel that has the same user
ID, or by a forced release at any panel.
 Note: a protect prevents others from routing to a destination; a lock prevents anyone — even
the user who issued the lock — from routing to the destination.
 You may lock a protected destination, but you cannot change a locked destination to a
protected destination directly. You must first unlock it.
MD Mode
In MD mode, a protected destination has a “P” next to it when it appears in the display. When
you select a protected MD destination with a button, the ‘Destination Protect’ button goes
high-tally.
To protect or unprotect MD destinations, select the destinations and press a ‘Destination
Protect’ button.
X-Y Mode
In X-Y mode, you may protect or unprotect the current destination on each of its levels. Select
the level(s) and press the ‘Destination Protect’ button to perform the protect. Select protected
levels and press the ‘Destination Protect’ button to unprotect them. A protected level has a “P”
next to it when it appears in the display.
See Lock, Protect, and Release on page 39.
Free Source
This button selects a phantom device that can be used to release or “free” devices on the data
(control) level. A free source can also be used with tielines to free the tieline for others to use.
Use it as if it were a source.
(The actual free source is configured in the Level Set Details page of NV9000-SE Utilities.)
Hold
The ‘Hold’ button is a toggle. Press it once to activate “hold” mode, press it again to deactivate
“hold.” The button is high-tally when hold mode is active and low-tally when it is not.
You can activate or deactivate hold mode at any time during an MD selection or a breakaway
selection in X-Y mode. Your selection remains intact and the panel subsequently operates in
hold mode or non-hold mode according to the hold button state.
MD Mode
In MD mode, turning hold mode on allows you to select more than one destination button at a
time. When you select a source, the source applies to all selected (high-tally) destinations. If hold
is still on when you press ‘Take’, the selected destinations remain selected and the display
reflects the selected destinations. The buttons for the selected destinations remain high-tally.
