The other is for use with the tables of the upper region.
“Live” Changes
Changes made in the ‘Current’ table result immediately in changes in the crosspoint matrix of
the router. (Use caution in the ‘Current’ table for a router that is on air.)
(See Routing on page 141.)
Salvos
Using the ‘Crosspoints’ page, you can take a “snapshot” of a crosspoint matrix. MRC calls such
snapshots salvos. A salvo can be saved as a separate file. If a system failure occurs, the salvo can
be uploaded to reset the crosspoint matrix in the router.
For information on creating, updating, and deleting salvos, see Using Salvos on page 109.
Locks and Protects
In the NV9000 router control system, and perhaps other router control systems, sources and
destinations can be (1) locked or (1) protected. The ‘Crosspoints’ page of MRC recognizes desti-
nation locks and protects, but does not recognize source locks and protects.
Destination Lock: no one, including the person who locked the destination, may route to
the destination until the destination is released (unlocked).
Destination Protect: no one except the person who locked the destination may route to the
destination until the destination is released (un-protected).
Locks and protects are applied in the router control system, usually at a control panel. Typically,
a lock or protect is “owned” by the person who set it and can be removed only by the owner or
an administrative user. The ‘Current’ table of the ‘Crosspoints’ page has a column labeled ‘LID’
—
for “lock ID” — that gives an ID representing the “owner.”
At present, locks and protects can only be released globally. The ability to release individual
locks and protects is planned for the future.
