GLOSSARY
Bus A bus is the channel or path between the components in the
matrix along which electrical signals flow to carry information from one
component to the next. In the Eclipse matrix the bus is located in the
etched surface of the midplane.
Call Signal A call signal is an electronic signal sent from one station or
interface to another. A call signal can be audible and/or visual.
Typically a call signal is sent to get the attention of a station operator
who may have turned down their intercom speaker’s volume or
removed their headset. It can also be sent to activate an electronic
relay.
Category-5 cable EIA/TIA 568 category specification relating to
network cabling. Shielded category-5 cabling is required for Eclipse
matrix wiring.
Central Matrix The term “central matrix” is used to differentiate the
central hardware and software of the intercom system from the
connected remote devices. The central matrix consists of: (1) the metal
housing for the circuit cards and power supplies, (2) the circuit cards,
(3) the power supplies, (3) the rear panel connectors which connect
the matrix’s hardware to stations, panels, and interfaces.
Destination A device—such as an intercom station, beltpack, or
interface—to which you send audio signals. The device from which you
send audio signals is called a “source.”
Duplex All real-time communication between individuals talking face to
face is full duplex, meaning that you can both talk and listen
simultaneously. The Eclipse Median provides full-duplex audio.
Eclipse Configuration System Web-based software program that
guides the operation of the central matrix circuit cards and connected
panels, stations, and interfaces.
Ethernet International standard which describes how information is
transmitted across a network. Provides for the efficient organization of
network components.
IFB “Interruptible Foldback.” The term
“
foldback
”
refers to sending
“ program ” audio, or some other audio mix, back to the announcer
while he is on the air. Doing so allows the announcer to monitor
himself, other announcers, videotapes of commercials, or some mix of
sources, while he is on the air. This is typically found in television news
and live broadcast events.
The announcer typically wears a small ear piece so he can hear the
selected foldback audio mix. When a director wants to give directions
to the announcer on air, or to announce changes in the program, he
