Glossary
A
AMS – The Administrative Management System. AMS is an optional add-on to Phoenix. Its
primary purpose is to control the bells and Public Announcement capabilities in K-12
environments.
Axcess – The predecessor to NetLinx, Axcess is an earlier control system available from AMX
Corporation. Axcess was the control system utilized by Synergy. While Phoenix is compatible
with many Axcess devices, the Axcess central controller is no longer used as the central “brain”
of the Phoenix Media Retrieval and Campus Automation application.
Axlink – A network of cables that connect devices to the NetLinx or Axcess central controller.
Axlink is the data bus that is used to enable communication from the controlled devices to the
central “brain” of the system.
B
Baseband – One of three possible audio/visual distribution methods supported by Phoenix, the
other two being broadband or RF and digital. A baseband distribution network employs a router
or switcher to route audio/video signals from a source to a destination. Routers contain inputs
and outputs. The inputs are wired directly to the signal that is to be distributed throughout the
campus. The outputs are wired directly to the destinations that should receive the audio/video
signals.
Broadband – One of the three possible audio/visual distribution methods supported by Phoenix,
the other two being baseband and digital. Broadband is often referred to as an “RF distribution
network.” Broadband distribution networks employ combiners to modulate audio/video signals to
a frequency. The destinations are then tuned to the appropriate frequency by Phoenix, enabling
transmission of the audio/video feeds throughout the campus. The broadband distribution
network is analogous to the standard cable feed that is used in some homes.
C
Channel Ring – The list of authorized broadband channels or baseband inputs that a room can
tune to. The Channel Ring is defined for the Distribution Group (Combiner or Switcher) that a
room is connected to. When a user presses the Source Up/Down
buttons on the handheld
remote control or the web client or Client32 interfaces, the room will be tuned to the next channel
or crosspoint in the list. The Channel Ring is also known as the “Surf Ring.” See section 10.1.3
for more information.
Combiner A device used to modulate audio/video signals to a particular frequency so that the
signals can be tuned by display devices. See the definition of broadband for more information.
CTON – An infrared timing value that applies to Television Managers only. The CTON value is
the IR pulse length used when pulsing channel digits. This value is measured in 10ths of
seconds. Therefore, to set a value to 5 seconds, you would enter the value of 50. If you enter
only the number 5 then you will be setting the corresponding timing parameter to ½ second.
CTOF - An infrared timing value that applies to Television Managers only. The CTOF value is the
pause time between channel digit IR pulses. This value is measured in 10ths of seconds.
