C-2000  DIGITAL AIRBORNE  TELEPHONE  SYSTEM
1.0 INTRODUCTION
The MagnaStar Digital  Airborne Telephone System brings complete telephony service to business
and general aviation  aircraft.  From the GTE  Airfone  digital  air-ground telephone system to  SA TCOM
connections, the MagnaStar C-2000 offers a full-featured communications environment.
1.1  Operational  Features
The C-2000 system brings the office to the sky.  All  the communication features required in the
office are made available in the airborne enviromnent. The system has been designed to provide these
features with high quality of service and ease of operation.
Direct  Dialing -  Callers can dial direct through the North American Public Switched Telephone
Network (PSTN) or to international destinations. Calls can be charged to the
corporate (MagnaStar equipment owner) account (I  + dialing) or to major credit
cards (0 + dialing). Of course, operator assisted (0 +) calling is also available.
Continuous  North
American  Coverage
-  The MagnaStar Digital  Airborne  Telephone operates over the GenStarTM digital
telephone system from  GTE  Airfone,  which  offers  continuous North  American
coverage with  automatic cell-to-cell  voice-call hand-off without  call interruption.
Ground  system covernge is  available  throughout  the  United  States, southern
Canada, and Mexico.
SA TCOM  Connection -  The MagnaStar system connects to SA TCOM  systems, on aircraft so equipped, to
provide easy access and choice of communication link  to callers from any cabin
handset.  The C-2000 supports both analog interfaces and the digital  CEPT-EI
interface to multi-channel SA TCOM  systems.
Cabin  Management  -  MagnaStar air-ground communications can  be  provided to  aircraft  using
Connection  separately supplied cabin management systems. Contact  MagnaStar engineering
support on the StarLine at (888-246-ST AR)  for  further  infonnation  and specific
interface availability.
Cellular  Connection
HF Connection
-  The MagnaStar system connects to the Cellular Phone (Cell Phone) System
through the use of a Cell Phone Interface (CPI) to provide easy access to the
Cellular system whenever the aircraft is on the ground.
-  The MagnaStar system connects to HF radios, on aircraft so equipped, to provide
easy access to that communication link  from any cabin handset. Push-to-talk
(PTT) control is voice activated, eliminating the need for a PTT switch on the
handset.
Multiple  Calls -  The MagnaStar system allows two  simultaneous phone calls of  any type (voice,
data, FAX,  TDD)  over the GenStar system. Additionally,  simultaneous calls can
be made through a HF radio and over as many SA TCOM  channels as supported
by the appropriate equipment, if  so configured.
Uplink  Calls -  Uplink  telephone numbers (or  SATCOM "Terminal IOlt  numbers) can be
assigned to the aircraft or to each handset. For individuals with an AirCall
number from GTE Airfone and signed on to the system, calls will  be routed
directly to their seats. When a call is received, the calling number is displayed
and the called party has the option of accepting the call or not.
MagnaSlar is a trademark of the Raytheon Systems Ccxnpany. GenSIar is a lJademark of GTE Airfone  blcorporated.

Conference Calls Conferences can be set up between multiple  parties on-board and on the ground,
over any of the available links (GenStar, SATCOM, HF).
Call Transfer Incoming and outgoing calls can be transferred to other handsets on-board the
aircraft.
In-Plane Calls Seat-to-seat (cabin-to-cockpit) calling is a standard feature.
Speed Dialing With the MagnaStar system. callers can store and quickly call frequently called
numbers as well as access services offered by GTE Airfone (hotel, car rental,
weather, etc.).
Multiple  Phones The basic C-2000 system allows installation of up to nine independent (non-party-
line) telephone handsets. A  system configuration allowing  up to fifty  handsets is
currently being developed.
Fax I Data Modem The MagnaStar system provides  RJ.II  jacks  for  connection of  caller's  fax  or
personal computer modem equipment. The RJ.II  jacks are integral to the handset;
they may be remoted so that the fax / modem cable does not interfere with  use of
the handset. The system is designed to support high quality  (low  error rate) voice
band data transmissions at  2400  bps;  4800  bps, and 9600  bps.  Higher  rate
capabilities are in development by Raytheon and GTE Airfone engineering.
TOO Customer supplied TOO equipment is supported by the MagnaStar system, via the
handset itself or the RJ-II  jack.
Call  Charging Service charges for calls made with the MagnaStar system are billed directly to
the equipment owner's account (1 + calls) or to credit card accounts (0 + calls).
Direct charged (1 +) calls can be blocked, for example during charter use of the
aircraft.
Privacy The MagnaStar system uses an advanced modulation and signaling scheme which
offers  inherent communications privacy.  Your  conversation is  protected from
casual listening by others having 'scanners' or by even similarly  equipped aircraft.
(This privacy is only limited by the normal private-line telephone service through
the PSTN. Additional  security can be provided with optional features.)

C-2000 DIGITAL AIRBORNE  TELEPHONE  SYSTEM
1.2 Equipment Description
The  MagnaStar C-2<XX> system is designed with the business aircraft in mind.  With two air-
ground voice channel operations as a standard feature, the C-2<XX> consists of  an Airborne Radio
Telecommunications Unit  (ARTU),  an antenna, a duplexer, a mounting tray for  the ARTU,  one or more
Cabin Data Bus Repeaters (COBRs), and one to nine telephone handsets. Optional equipment includes one
to three Analog Interface Units (AlU),  a Call  Alerter  Switch (CAS),  Cell  Phone Interface (CPI), Cockpit
Headset Interface Panel (CHIP), and other specialized devices.
A&JJ1:  The ARTU  provides the private automatic base exchange (P ABX)  features, controls the C-2000
system. and contains the receiver-transmitter functions for radio transmission.  This digital  radio has been
implemented  using  state-of-the-art  multiple  digitaJ  signal  processor  techniques  to  provide  accurate
waveform  control  and  noise-free,  reliable  communications  in  the  noisy,  fading.  high-Doppler  signal
environment  seen in  jet  aircraft-to-ground  communications.  Reliability  is  further  enhanced by  the
automated assembly and test techniques used to manufacture the high density surface-mount-device circuit
cards.  Should any problem occur, built-in-test  identifies the source of the problem for quick circuit  card
replacement and return of the unit to service.
Antenna /  D~lexer:  The antenna is a low drag, quarter wavelength design swtable for use on high
perforDJance jet aircraft. The duplexer is a passive signal filter-combiner that combines the receive and
transmit lines to the common antenna.
~:  The data and control interface to the ARTU  is by means of a high speed time division  multiplexed
digital bus operating as a local area network (LAN).  User interface devices such as handsets, fax machines,
modems, etc. connect to  the system via this  LAN.  There are two  different  nx>dels of  the CDBR.  The
CDBR-l  (~ell)  provides for physical connection of up to two digital  handsets (with  their  RJ-ll  jacks
for the fax I modem connections) to the LAN  bus.  The CDBR-2 (model 2) provides two analog interface
connections, each of  which  can support either a four  wire  analog handset or  two  wire  data for  direct
connection of  a fax  machine or  modem  Additionally,  the  CDBR-2  provides  a  separate interface for
connection of a digital handset.
Di2ital  Handset: The telephone handsets have been selected for performance and reliability.  The handsets
contain noise-canceling microphones to overco~  the aircraft noise environment; audio is digitized at the
handset to further ensure clear communication.  Special function  keys and a liquid  crystal display allow
easy use of  all  options  available to  the user.  The  digital  handsets are offered  with  varied  mounting
provisions to fit any installation requirement.  Handsets are offered with  a) a standard build-in  style mount
to hold the handset when not in  use, with  a ratcheting cord reel, b) that version with  a bulkhead mounting
adapter, c) the handset and cord reel without  a mount, for  custom mounting, and d) a "curly-cord"  (like
standard office phones) with a plug for the ability  to relocate the handset to various locations wired with the
matching jack.  Variations a - c also are available with  the RJ-ll  jack  remoted from the handset, to be
located where it  best fits  in the interior  design of the aircraft.  All  variations come in  four colors:  white,
platinum, pepper dust, and black.  Develop~nt  is on-going for additional telephone handset options.
AllJ.:  The AIU  can be used to connect an analog SA TCOM unit, a Cel1 Phone Interface (CPI), a HF radio,
or a Public Address (P A)  amplifier,  and/or other communications devices to the MagnaStar system  The
AIU  bas been designed with  electrical  interfaces to  optimize  the  connection to  any  analog-interface
SA TCOM  system selected by the custo~.  Separate connections are provided to accotmt for variations in
audio-line impedance and level and in the hook switch and status interfaces between SATCOM equip~nt.
HF  radio  connections can be made directly  or  through the aircraft  audio control  panel.  The  varying
requirements for the SA TCOM  and HF interfaces led to an AIU  design that offers the flexibility  to connect
a wide variety of equip~nt  and systems to the C-2000.  AIUs  interface to the ARTU  over the LAN,  like
the COORs.

C-2000  DIGITAL AIRBORNE  TELEPHONE  SYSTEM
~:  The CAS provides ten switches to  control  call alerting devices (supplied by the installer)  such as
bells, lights, cabin chime, etc.  (Even in the relatively  noise-quieted cabins of business jets,  the ambient
noise can make it difficult  to hear the electronic ringer of the standard handset.  Increasing the volume of
the handset speaker could be annoying should the handset be close to a user's ear when it rang.  A separate
alerter avoids this problem and allows for installation of the handsets in enclosed compartments.) Single or
multiple  switches can be assigned to  a handset and to  multiple  handsets; and the cadence of  the "ring"
pattern can be controlled, giving  a great deal of flexibility  to customize uplink  call notification.  One CAS
is used per aircraft; it connects to a digital  handset port of any of the CDBRs in the system. The CAS may
also be used to  signal when Air-Ground,  SA TCOM  or  HF  services are available  or  when one or  more
particular handsets are in use.
Miscellaneous: The MagnaStar system can interface to many other communications equipment. The
"-802" modification  to the ARTU  provides a CEPT -EI  interface to connect directly  to SA TCOM  systems
or to cabin management equipment.  The flexibility  is built  in  to the system to  accommodate customer-
unique requirements with minimum new development.
1.3 Installation  Summary
The  ARTU  is  installed  in  an ARINC  style  mounting  tray  using two  type  A  hold  downs.  It  is
designed for installation in pressurized or non-pressurized locations.  The mounting tray provides an
air plenum and fan for cooling.  The fan is quiet enough to allow  cabin installation.  The duplexer
can be mounted in any convenient location between the ARTU  and the antenna. The antenna comes
with  a standard six hole mounting flange.  As an option,  a four  hole flange is available for  direct
replacement of  standard 450  MHz  radio  telephone antennas.  The  handsets are  designed for
installation  in  any  convenient  area of  the  cabin.  Custom  mounting  provisions  can be  readily
provided.

information  for the ARTU,  CDBR-1,  CDBR-2  and AIU.
4.2 Cable Check-Out
This  section  provides  some  basic  instructions  for  inspecting  the cable  prior to installation  of the
MagnaStar  equipment.
ARTU  Data, Inter-CDBR/AIU and Handset Cables
These cables should be verified for correct  wiring prior to installation of MagnaStar equipment. Cable
check-out  should  include  a visual  inspection  for  bent or damaged  connector  pins.  These  cables  should
then  be checked  for  proper  interconnection.  The  required  check  list is:
SIGNAL CABLE INSTALLATION CHECK LIST
a)  Visually inspect cables for bent or damaged connector pins.
b)  Visually inspect for proper back shell installation.
c)  Continuity check for proper pin-to-pin interconnection between cable connectors.
d)  Check for open circuit condition between each pin and the back shell.
e)  Check for open circuit condition between each pin and all other connector pins.
f)  Continuity check from back shell to back shell for shield connection to connector back shells.
Notes:

5.0 EQUIPMENT INSTAllATION
5.1  INDIVIDUAL EQUIPMENT INSTAllATION
After cable check-out. the aircraft is ready for the installation of the MagnaStar C-2000
equipment. The following check-out must be followed prior to application of aircraft power.
ANTENNA
a)  The Antenna should be mounted to a paint free metal grounded surface.  Ensure that
the screw contact (countersink) surface of the Antenna is free of paint. The screw
threads must make metallic contact to the ground plane. The ground plane must
extend at least one foot radially from the Antenna.
b)  After installing the Antenna, measure the DC resistance between the Antenna and the
airframe.  Bonding resistance must be less than 2.5 milliohms.
c)  Check that the antenna cable to Antenna connection is mechanically secure.
d)  Ensure that the minimum distance between the C-2000 antenna and any antenna for
equipment operating in the 800 Mhz to 1200 Mhz frequency band (e.g. DME,
Transponder. TCAS) shall be 3 feet. minimum. The minimum distance between the
C-2000 and any other antenna shall be two feet.
e)  It should be noted that the MagnaStar system is a line of sight system that operates
with equipment located on the ground. The MagnaStar antenna should not be located
in position that will be blocked by other mechanical devices in close proximity or easily
shadowed when the aircraft maneuvers during flight.
5.1.2 DUPLEXER
a)  After installing the duplexer. measure the DC resistance between the duplexer and
the airframe.  Bonding resistance must be less than 2.5 milliohms.
b)  Check the antenna cable. transmit cable. and receive cable connections to the
duplexer.
These connections must be mechanically secure so they will not become loose
during aircraft
vibration.  The SMA connectors (transmit and receive connectors) should be
tightened to 7
in-ibs of torque if using a 620317-1 duplexer.
ARTU MOUNTING TRAY
a)  After ARTU Mounting Tray installation. measure DC resistance between the ARTU
Mounting
Tray and the airframe. Resistance must be less than 2.5 milliohms.
b)  Check the input and exit airflow paths from the fan in the ARTU Mounting Tray.
Airflow paths
must be clear of any obstructions that could restrict cooling.
