User’s Guide
The router’s port numbering scheme associates 16 audio port numbers with each video port.
Video port 1 carries audio ports 1–16, video port 2 carries audio ports 17–32, and so on.
This numbering applies to an embedder card or disembedder/embedder card in any slot. A card
in slot 1 provides video ports 1–8 and 10–17 and audio channels 1–128 and 145–272. The 9th
and 18th connectors are unused and the corresponding ports (video ports 9 and 18 and audio
ports 129–144 and 273–288)
do not exist
. Thus, a card in slot 2 supports video ports 19–26 and
28–35 and audio channels 289–416 and 433 –560. Its 9th and 18th connectors are also not used.
A card in slot 3 supports video ports 37–44 and 46–53 and audio channels 577–704 and 721–
833, and so on.
Consecutive embedder or disembedder/embedder cards increment by 18 video ports and 288
audio channels. Consecutive cards follow the slot ordering for port numbers. See
Slot Order for
Port Numbering
on page 37.
The numbering scheme for hybrid expansion embedder output cards and disembedder/
embedder output cards (used by the expanded NV8576-Plus only) is like the numbering scheme
for disembedder input cards. (Expansion embedder output cards and disembedder/embedder
output cards have 8 outputs.)
Differences
Disembedder/embedder output cards differ from embedder output cards because the disem-
bedder/embedder cards support what is called
pass-through audio
. See
Pass-Through Audio
on
page 76.
IP Gateway Cards
IP gateway input cards receive up to 8 video streams over 3 10GE Ethernet connections. IP
gateway output cards transmit up to 8 video streams over 3 10GE Ethernet connections.
Video streams are mapped into to the router port numbering using the IP gateway card’s
internal browser application.
The IP gateway input card, aside from the fact that it has SFP connectors and receives patck-
etized video, is in fact a disembedding input card and its ports, having been mapped into the
port space of the router, can be configured as can any disembedder port.
The range of ports for any IP gateway input card is the same as for the disembedder cards. See
Figure 2-3.
The IP gateway output card, similarly, is an embedding output card and its ports, having been
mapped into the port space of the router, can be configured as can any embedder port.
The range of ports for any IP gateway output card is the same as for the embedder card.
However, only the first 8 ports are used; the other ports (9–18) are ignored (at this revision of the
IP card). Again, see Figure 2-3.
There are no IP gateway input cards for the NV8140. There are no IP gateway expansion output
cards (for the NV8576-Plus).
At present, IP gateway cards, input or output, can be used only for tielines.
See Chapter 11,
IP Gateway Cards
, for details.
