Clear-Com HX System Frames - Manual (Page 70)

Partyline A wired shared communication system based on a single
screened pair of wires. See the Encore range. Matrix requires the
CCI-22 to interface to it.
Port Any of the input/output connections (RJ-45 connectors) on the
back panel of the central matrix. These connectors and the
attached cables connect the central matrix to remote intercom
devices. The term port emphasizes that the connection is a portal
between the central matrix and the remote intercom devices.
Program Any separate audio source that is fed into the intercom channels.
In television applications, for example, the program audio is the
audio that is broadcast on air.
Rack Unit (RU) Standardized unit of mounting space on a rack panel. Each rack
unit is 1.75 inches (44.45 mm) of vertical mounting space.
Therefore 1 RU is 1.75 inches (44.45 mm) of vertical mounting
space, 2 RU is 3.5 inches (88.9 mm), 3 RU is 5.25 inches
(133.35mm), and so on.
Remote panel Any intelligent intercom device connected to the back-panel ports
of the matrix. This term does not refer to devices connected
through interfaces.
Sidetone The sound of the panel operator’s voice, as heard in their own
earphone(s) as they speak.
Source In this guide, the term source refers to a device (such as an
intercom panel, interface, or beltpack) that sends audio into the
matrix. The device to which audio is sent is called a destination.
VOX In the Eclipse HX system, when audio at a panel exceeds a
threshold, a light switches on at the panel’s port card to visually
cue the operator. The threshold level is set in the EHX
configuration software.
V-Series User panels used with Eclipse HX systems, providing advanced
intercom facilities. Available in rack mount and desktop formats
(lever key, pushbutton and rotary versions).
I-Series user panels are also supported (see above).
