User’s Guide
 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.
The ‘Destination Protect’ button text is normally “Dest Protect” and when a selected MD desti-
nation is protected, the button legend becomes “Dest Unprotect.”
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 65.
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.)
The default button text is “Free Source” but the button can have any legend.
Forward
This button displays and activates the next button page of an automatically generated list.
A forward button is never high-tally. A forward button is generated by the system when the
current page of a list has more than 28 or 29 elements. Otherwise, the list is at its last page and a
forward button would do nothing. Forward buttons are always accompanied by “back” buttons.
See also Back .
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.
The default button text is “Hold Preset” but the button can have any legend.
