NV8500 family Digital Routers • User’s Guide 1
1. Introduction
The NV8500 family is a series of highly flexible high-density routers supporting Standard Defini-
tion (SD), High Definition (HD) and 3.0
Gb/s (3Gig) video signals, and AES Asynchronous audio
signals. This section provides an overview of the NV8500 family of routers, including signal flow
and rates, power supply, active cards and frame expansion. It is recommended that you read this
section before starting any installation tasks.
Product Overview
The NV8500 family is composed of several routers that are either standalone routers or routers that
can be connected together to create larger switching matrices called “expandable” router frames.
Expandable router frames are denoted by the word “Plus.” A fully non-blocking matrix architecture
allows for one-to-one and one-to-many routing. Because inputs and outputs are independent, con-
figurations do not have to be numerically squared or identical in number.
Standalone routers allow for configurations as small as 9 inputs and 18 outputs, increasing in incre-
ments of 9 inputs or 18 outputs. Expandable routers allow for configurations as small as 9 inputs
and 9 outputs, increasing in increments of 9 inputs or 9 outputs. When two routers are connected
together, the number of inputs and outputs that can be switched doubles. The two connected routers
are considered a single matrix.
The following is a list of routers within the NV8500 family.
Input cards, output cards, control cards, crosspoint cards, monitor cards, and power supply modules
are “hot swappable” and installed through the front of the frame for easy access. The rear of the
router features a back plate into which backplanes housing different types of connectors for receiv-
ing and distributing signals are installed. Each backplane receives or distributes signals for a single
card allowing for maximum switching configuration flexibility. The back plate also contains con-
nections to system functions, such as a router control system, alarms or reference signals.
