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.
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.
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.
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 Omega matrix provides full-duplex audio.
ECS Eclipse Configuration System. Software program that guides the
operation of the central matrix circuit cards and connected panels.
EMS Element Management System. Software program that is used to
manage the Concert server system resources.
Ethernet International standard which describes how information is
transmitted across a network. Provides for the efficient organization of
network components.
