The glossary gives a brief explanation of some of the main terms that you might encounter
in this manual.

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 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.

intercom system from the connected audio devices. The central matrix consists of:
