How the System Works
The MagnaStar ® C-2000 Digital Airborne Telephone provides the
general aviation marketplace – business, governmental and private
aircraft – with access to advanced telephony services previously
available only onboard commercial aircraft.
The MagnaStar system was specifically designed to provide this capa-
bility onboard these aircraft, where weight, size, and pressurization
considerations are extremely demanding. As a result, the system can
be used to place and receive voice calls, send data transmissions via
modem as well as send and receive facsimile transmission, all from
the comfort of your aircraft cabin.
A central radio processor onboard each MagnaStar-equipped aircraft
coordinates and controls the cabin telephone handsets for all voice
calls, data calls and in-cabin intercom functions. The system links
with the Airfone Ground Station Network for channel selection and
call hand-off operations.
During flight, the MagnaStar system continually scans and monitors
ground-based radio cells for the best usable communications channel.
The availability of a channel is indicated on the handset’s LCD display.
When a call is initiated, the system searches for the ideal channel and
connects the calling and receiving parties. The system will accommo-
date multiple handsets and two independent air-to-ground voice, fax, or
data calls may be placed on the system simultaneously. Digital tech-
nology ensures reliable, clear connections at all times.
All operations are performed using the system handset. Each
handset features adjustable volume with push-button controls
and a telephone-style keypad with two additional keys, “+”
and “End Call.”
The keypad is used to dial calls and select various options as
described later in this manual. The handset’s LCD display presents
useful information and “menu”-style selections thereby prompting
users through the operating steps so that separate instructions
are seldom required.
The handset also features a credit card reader which allows
optional billing of calls to individual user accounts.
