DHP Service
Configuration Process
7 In NV9000-SE Utilities
a Ensure that a level set exists that includes all audio levels in use.
b Explicitly define all audio levels for standard inputs and outputs that can be switched
using DHP. [For standard I/O that will never be switched by DHP, this is not necessary.]
8 In NV9000-SE Utilities, if your router has MADI ports
a Add 40,000 to any and all MADI port numbers. (DHP requires this.)
b Add 40,000 to the audio matrix size.
9 In NV9000-SE Utilities, clear the DHP portion of the router’s crosspoint matrix.
10 Remove any previously defined sources and destinations from the DHP core portion of the
NV9000 configuration.
11 Finally, write the new configuration to the NV9000 and restart the NV9000. Then set the DHP
service to “automatic” and start the DHP service.
Configuration Process
[1]
DHP Core
In your analysis of the DHP requirements of your router, you will have determined the number
and type of hybrid cards to include in the DHP core.
If you are adding DHP to an existing router, place the disembedder (input) cards and embedder
(output) cards that form the DHP core in the router. Also place the cards’ matching backplane
connector modules. The cards in the DHP core do not have to be contiguous.
If you are starting with a new unconfigured router, it is probable that the cards belonging to
your DHP core have been installed at the factory.
In either case, make sure that the cards and backplane modules are installed properly and make
careful written notes about which slots you have used for the DHP core. The port numbers for
the cards in those slots are critical to the configuration process.

Router Levels
DHP requires that your router have exactly one ‘Digital Video’ partition and one ‘Synchronous
Audio’ partition. Partitions of other types are acceptable, such as a monitor partition. Use the
‘Router Levels’ page in MRC to define the partitions. This example is typical for an NV8280:
