Inputs and Outputs
Types of Input and Output
Expansion cards are applicable only to the NV8576-Plus expanded router. (The NV8576-Plus
expanded routers do not accept IP gateway output cards. No expansion IP gateway output
cards exist yet.)
The expansion output cards all have two inter-frame connections, in addition to their output
connectors.
The “special functions” of the disembedder/embedder cards are (1) null audio and (2) pass-
through audio. See
and
There is no M3 expansion output card and there is no M3 input card.
Backplanes
Backplane modules have signal connectors of 3 types, in general:
•
Coax (DIN 1.0/2.3)
•
Fiber optic (IP gateway cards, having SFP connector modules housing LC connectors)
See
•
WECO quick-release connectors (5-pin or 3-pin, for twisted pair wiring).
