NV8500 Series
User’s Guide
A (hybrid) embedder card and a (hybrid) disembedder/embedder card each have 16 video ports.
The 9th and 18th video ports and the 16 audio ports each of those ports would have do not
exist. The 9th and 18th connector on the card’s backplane go unused.
Nevertheless, nonexistent video and audio ports and their unused connectors are counted in
the port numbering.
Similarly, an embedder expansion output card has only 8 video ports. The 9th video port and
the 16 audio ports it would have do not exist. Therefore, the 9th connector of its backplane is
unused:
Fig. 2-3: Embedder and Disembedder Port Numbering
Audio port ordering for frame sync input cards is the same as for disembedder cards.
MADI Cards
For all NV8500 routers except the NV8140, a MADI (i.e., 3Gig/TDM) input card has 8 video ports
and 1 MADI input; the 9th connector of its backplane is for MADI, up to 64 channels. For these
cards, only 64 audio ports of the 144 in the card’s space exist.
For the NV8140, a MADI (i.e., 3Gig/TDM) input card has 16 video ports and 2 MADI inputs. The
9th and 18th connectors of its backplane carry MADI, up to 64 channels for each connector. For
these cards, only 128 audio ports of the 288 ports in the card’s space exist.
A MADI (3Gig/TDM) output card has 16 video ports and 2 MADI outputs. The 9th and 18th
connectors of its backplane carry MADI, 56 or 64 channels for each connector. For these cards,
only 128 audio ports of the 288 ports in the card’s space exist.
