Glossary
DSP Digital signal processing.
A DSP sub-module that can be installed on the NV7512 router crosspoint card. The
DSP sub-module enables gain adjustment, phase inversion, crossfade, and channel
summing functionality for audio stereo signals. The DSP module is no longer available.
DTE Data Terminal Equipment (an RS-232 term).
EEPROM (EE or “serial EE” for short). Electrically erasable programmable read-only memory. In
the context of UniConfig, this is non-volatile memory associated with a router control
card. EE retains its data indefinitely in the field (unless it is reprogrammed).
EIA Electronic Industries Alliance. The EIA (until 1997 Electronic Industries Association) is a
trade organization for electronics manufacturers in the United States. EIA is accredited
by the American National Standards Institute (ANSI) to help develop standards on
electronic components, consumer electronics, electronic information, telecommunica-
tions, and Internet security.
ESD Electrostatic discharge
HD High-definition (video). An HD signal is a serial digital video format that conforms to
the SMPTE 292M standard.
Hot-
Swappable
A module that is “hot-swappable” can be safely removed and/or installed while power
is applied to the system.
I/O Inputs and outputs.
The term “input port” is used interchangeably with “input” and the term “output port”
is used interchangeably with “output.”
Jumpers Jumpers are usually small conductors, in plastic sleeves, that fit over a set of pins on a
circuit board. The placement of jumpers can enable or disable a board function, or
configure a board function.
LED Light Emitting Diode
Matrix In general, a 2-dimensional array.
In NVISION series routers, the switching mechanism is called a crosspoint matrix, that is,
a 2-dimensional array of crosspoints. A crosspoint is a theoretical point where an input
is connected to an output.
Module Any removable subassembly may be called a module.
UniConfig uses the term module to refer to I/O cards, backplane modules, monitor
cards, control cards, etc.
MRC A software application that configures and manages NV8500 hybrid routers primarily
and that can perform some management tasks for other NVISION series routers.
Operator The term operator usually refers to a control panel operator — a user that is not a
system administrator. An operator is the person responsible for making routes.
P2P An abbreviation for “point to point.”
