DHP Service
Configuration Process
There are two different initialization files needed for the DHP service to operate.
• HybridCards_xxxx.cfg
• HybridPorts_xxxx.cfg
where xxxx is a “well-known port” for this router that you specified earlier in the NV9000’s
‘Control Points’ table.
 You must have one copy of these files for each port used. For instance, if you use ports 9476
and 9477, you will need 4 initialization files:
HybridCards_9476.cfg ,
HybridCards_9477.cfg , HybridPorts_9476.cfg , HybridPorts_9477.cfg .
As a reminder, these are the unassigned “well known ports”:
9451–9499 9630–9699 9701–9746 9803–9874
The HybridCards_XXXX.cfg file lets the software know what cards are located in the slots of
the hybrid router frame(s). The file contains commands that identify the type of card in specific
slots. The file allows one command per line. The commands are very simple.
The HybridPorts_XXXX.cfg file tells DHP the locations of the designated pairs of disem-
bedder ports and pairs of re-embedder ports. (The DHP service to be configured on a port-by-
port basis.) The ports you list in the file belong to the “DHP core.”
‘HybridCards’ Files
A ‘HybridCards’ file tells DHP what types of cards are in which slots. This is the same information
you specified in MRC in step 2-1. This information, however, resides in the NV9000 instead of the
router control card.
There are 4 commands that you can write in the file.
F ‹frame type› Acceptable
3
values for ‹frame type› are
8144 — NV8144
8280 — NV8280
8576 — NV8576
8577 — NV8576-Plus
S ‹section› Acceptable values for ‹section› are IN or OUT .
C ‹slot› ‹type› Acceptable values for ‹type› are
0 — standard card
1 — MADI card
2 — reserved for future use
3 — disembedder or embedder card
Slot numbers must be in the range supported by the router.
END Indicates the end of a section.
 Note: The numbers representing card types in a ‘HybridCards’ file do not necessarily match
the numbering schemes for other software.
An F command must precede S or C commands.
An S command must precede C (card type) commands. Otherwise, DHP will not know whether
the cards defined are input cards or output cards. An END command must follow the last C
command of a section.
3. DHP does not (yet) support the NV8140. You cannot choose an NV8140 in the configuration file.
