GLOSSARY

Analog Port Any of the Eclipse matrix’s analog input/output RJ-45
connectors that are used to connect cable from the matrix to panels
and interfaces. Each “port” connects to a separate audio channel in the
matrix intercom system.

Alias label A label that is temporarily assigned and replaces a
previously labeled port or conference.

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 panel 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 panel 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.

Canvas The assignment area of Production Maestro which can have
any user labeled background.

Category-5 cable EIA/TIA 568 category specification relating to
network cabling. Shielded category-5 cabling is required for Eclipse
matrix wiring.

CellCom Digital wireless communications product. Sold under the
CellCom name in USA and as FreeSpeak in Europe and Asia.

Central Matrix The term “central matrix” is used to differentiate the
central hardware and software of the intercom system from the
connected audio 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.
4. The rear panel connectors which connect the matrix’s hardware to

panels and interfaces.

Conference An internal matrix virtual party line or busbar where many
panels and interfaces can talk onto or listen from the party line without
talking to themselves.

Destination A device such as an intercom panel, beltpack, or interface
to which audio signals are sent. The device from which audio signals
are sent is called a “source”.

Duplex All real-time communication between individuals talking face to
face is full duplex, meaning that they can both talk and listen
simultaneously. The Eclipse matrices provide full-duplex audio.
