Term Definition
Analog Port
Any of the Eclipse HX 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.
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 HX 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 (CAT5)
cable EIA/TIA 568 category specification relating to network cabling.
Shielded category-5 cabling is required for Eclipse HX 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:
• The metal housing for the circuit cards and power supplies.
• The circuit cards.
• The power supplies.
• The rear panel connectors which connect the matrix’s
hardware to panels and interfaces.
Conference An internal matrix virtual partyline 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 HX matrices provide full-duplex audio.
EHX EHX is the Eclipse HX configuration software. EHX guides the
operation of the matrix circuit cards and connected panels.
Ethernet International standard which describes how information is
transmitted across a network. Provides for the efficient
organization of network components.
