NV8576-Plus (Expanded)
The expanded NV8576-Plus has 8 monitor card slots, 2 cards in the upper output bay, and two in
the lower output bay of each frame.
For each frame . . .
The output monitor card in the upper bay samples output signals in the upper bay.
The input monitor card in the upper bay samples input signals in the upper bay.
The output monitor card in the lower bay samples output signals in the lower bay.
The input monitor card in the lower bay samples input signals in the lower bay.
The monitor cards in the upper bay of each frame receive samples from the monitor cards in
the lower bay.
The monitor cards in the lower bay of frame 1 receive samples from the monitor cards in the
upper bay of frame 2.
Your monitoring equipment receives samples from the monitor cards in the upper bay of frame
1 (the “primary” frame).
A MUX in each monitor card allows it to choose whether to sample signals from the I/O cards in
its own bay (and from which card) or from its link to another monitor card.
Thus, your monitoring equipment can sample any 2 outputs and any 2 inputs from either frame.
The NV8576 uses the monitor backplanes shown in Figure 5-1. An operator can select any 2
inputs and any 2 outputs for monitoring as long as the signals are from different input cards and
different output cards.
For installation and cabling instructions, see Making Monitor Signal Connections on page 94.
MRC
Operators can select inputs and outputs to monitor either using MRC or at NV9000 control
panels. See the Miranda Router Configurator User’s Guide or the NV9000-SE Utilities User’s Guide.
Note: older control cards support only output monitor signals. More recent control cards
support both output and input signal monitoring.

(Routers always ship with the latest of released software and firmware.)
To access and control monitor cards and signals properly, the router must be configured with a
‘Monitor’ level. Use MRC to do so. See the Miranda Router Configurator User’s Guide.
2. Control cards running the following application versions support the listed monitor signals:
SV0900-06, SV0901-05 and older — the control card supports output monitor signals only.
SV0900-07, SV0901-06 and newer — The control card supports both input and output monitor signals.
