Inputs and Outputs
Types of Input and Output
A MADI (3Gig/TDM) expansion output card has 8 video ports and 1 MADI output; 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 space of the card exist.

IP GatewayCards
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 range of video ports for any IP gateway input card is the same as for the disembedder cards.
See Figure 2-3.
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,
, for details.
