Configuring Routers
Router Levels Page
This illustration shows typical levels for a hybrid NV8280.
The table’s columns provides the following information:
Note: strictly speaking the “controller source” numbers and “controller destination” numbers are
really port numbers in the router control system, not source and destination numbers. Sources
and destinations in the router control system are aggregates of router ports, often spanning
multiple routers.
Level Types
There are many physical level types (corresponding to signal types as the column is labeled in
the table). The levels from which you may choose depend on the router you are configuring.
For the NV8500 family routers, these are the available level types:
• Asynchronous AES. Use a partition of this type if your NV8500 router has AES cards installed.
• Digital Video. Use a partition of this type for video signals of any type (e.g., 3Gig, HD, or SD).
• Monitor. Use a partition of this type to support input and output monitoring. (Monitor cards
must have been installed in your router.)
• Synchronous Audio. Use a partition of this type for NV8500 hybrid routers. Embedded (and
disembedded) audio and MADI signals are supported by this partition type.
Column Description
Level Number assigned to the level. A unique number is automatically assigned. If
you change the level, keep in mind that the level numbers must all be different.
Physical Input Start The physical input connector at which the level starts.
Physical Input End The physical input connector at which the level ends.
Controller Source Start The logical port number at which the level begins, for sources.
Controller Source End The logical port number at which the level ends, for sources. This number is cal-
culated. You cannot change it.
Physical Output Start The physical output connector at which the level starts.
Physical Output End The physical output connector at which the level ends.
Controller Destination
Start The logical port number at which the level begins, for destinations.
Controller Destination
End The logical port number at which the level ends, for destinations. This number
is calculated. You cannot change it.
Signal Type The signal type to be supported by the level. See Signal Types on page 143.
