21. Glossary
DSP DSP sub-module 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.
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, telecommunications, and Internet security.
ESD Electrostatic discharge
HD HD and HD-SDI are equivalent in Miranda terminology. An HD signal is a high definition, serial
digital interface 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 are the physical connections (e.g., BNCs) on the back of the routing switcher.
The term “input port” is used interchangeably with “input” and the term “output port” is used inter-
changeably with “output.”
Jumpers Jumpers are small, plastic sleeves that fit over a set of pins. The placement of the jumper either
turns a function on or off, or reconfigure a function.
LED Light Emitting Diode
Matrix 1. The rack-mounted UniConfig chassis or frame which contains the subassemblies (modules,
backplanes, power supplies, etc.) which comprise the UniConfig.
2. An X-Y array of crosspoint switches, a crosspoint matrix.
Module 1. In the UniConfig, modules are electronic assemblies that plug into the matrix. Modules include
but are not limited to input, output and controller printed circuit boards also called active cards.
2. Any removable subassembly may be referred to as a module. Router backplanes may occasion-
ally be referred to as modules.
Operator The term operator usually refers to users other than the system administrator. An operator is respon-
sible for making most of the routes.
P2P An abbreviation for “port to port”.
Physical Level In a Configuration Application system, a physical level is the same thing as a router. The idea is
that multiple routers provide different “levels” on which to switch the signals of devices. Any par-
ticular device might send or receive HD, SD, AES, time-code, or machine-code signals. A Config-
uration Application switches one type, or level, of a device’s signal set.
Physically
Contiguous Matrix modules are said to be in physically contiguous slots in a UniConfig frame when both the
inputs and outputs associated with those slots are in numerical sequence. For example, input slots 5
and 6 are physically contiguous because inputs 1-16 and 17-32 are in numerical sequence. In the
same way, output slots 4 and 16 are contiguous because outputs 49-64 (slot 4) and 65-80 (slot 16)
are in numerical sequence.
Port A port is the physical connection on a router. In a configuration application system, a port can only
be an input port or an output port.
Reference
Signal A timing signal used to synchronize events such as the switching of video signals during a specific
portion of the vertical interval. Reference signals are externally applied. In their absence, internally
generated signals are used to sustain operation.
