Excluding Crosspoints
Excluding Crosspoints
Crosspoint exclusions prevent certain sources from being connected to certain destinations. The
‘XPTExclusions’ table lists all crosspoint exclusions defined in your configuration. Using this
table, crosspoint exclusions can be added, deleted or changed.
Crosspoint exclusions must be defined in low-level detail. The exclusion connectivity is point-to-
point and port-to-port. To completely exclude a source from a destination, all physical levels of that
source must be excluded.
S Example: You want to completely exclude 6 sources from 12 destinations on 5 virtual levels
(SD, AES1/2, AES3/4, AES5/6, and AES7/8), which means there would be 6 × 12 × 5 = 360
exclusions. Each exclusion specifies two ports, so there are 720 ports to manage!
How to Add a Crosspoint Exclusion
1 Launch NV9000-SE. (See Launching and Exiting the Application on page 12.)
2 From the Navigation area, select the ‘Views’ pane and then ‘XPTExclusions’. The ‘XPTExclu-
sions’ table appears:

. A blank row is added to the bottom of the list of existing exclusions.
4 On the blank row, click in the ‘Physical Level’ field to activate it and select a physical level
from the drop-down list. (See Physical Levels vs. Virtual Levels on page 112.)
5 On the same row, enter the ‘Output Port’ in the field provided. The port number is the specified
physical level, corresponding to the destination you want to protect.
6 On the same row, enter the ‘Input Port’ in the field provided. The port number is the specified
physical level, corresponding to the source you want to exclude.
7 Repeat steps 3 through 6 until all ports are excluded as needed.
