Adding Virtual Levels and Removing Virtual Levels
Virtual levels are created as part of the procedure for creating a level set. A virtual level represents
a signal type used in your system, such as AES or HD. Unlike physical levels that represent physi-
cal divisions and are specific to a router or device, virtual levels are signal type abstractions that
can be applied to all routers and devices. (See
Physical Levels vs. Virtual Levels on page 112.)
Virtual levels can be created and added to a level set, or removed from a level set, at any time. Once
created, a virtual level is available for addition to any level set in the NV9000-SE system. When
removed from a level set, the virtual level is disassociated with that level set, but remains in the
NV9000-SE system and associated with all other level sets to which it was previously added.
When a virtual level is removed from a level set, if no other virtual level in the level set is mapped
to a signal type, all devices managing that signal type may no longer function correctly. Be sure
