1.2 EquipmentDescription
The MagnaStarC-2<XX>systemis designedwith the businessaircraft in mind. With two air-
groundvoice channeloperationsas a standardfeature,the C-2<XX>consistsof an Airborne Radio
Telecommunications Unit (ARTU), an antenna,a duplexer, a mounting tray for the ARTU, one or more
Cabin Data Bus Repeaters(COBRs), andoneto nine telephonehandsets. Optional equipmentincludesone
to three Analog Interface Units (AlU), a Call Alerter Switch (CAS), Cell PhoneInterface (CPI), Cockpit
HeadsetInterfacePanel(CHIP), andotherspecializeddevices.
A&JJ1: The ARTU provides the private automatic baseexchange(PABX) features,controls the C-2000
system.and containsthe receiver-transmitter functions for radio transmission. This digital radio hasbeen
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
automatedassemblyandtest techniquesusedto manufacturethe high density surface-mount-devicecircuit
cards. Should any problem occur, built-in-test identifies the sourceof the problem for quick circuit card
replacementandreturn of the unit to service.
Antenna/ D~lexer: The antennais a low drag,quarterwavelengthdesignswtablefor useon high
perforDJancejet aircraft. Theduplexeris apassivesignalfilter-combinerthatcombinesthereceiveand
transmitlinestothecommonantenna.
~: The dataandcontrol interfaceto the ARTU is by meansof ahigh speedtime division multiplexed
digital busoperatingasa local areanetwork (LAN). Userinterfacedevicessuchashandsets,fax machines,
modems,etc. connectto the system via this LAN. There are two different nx>delsof 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 modemconnections)to the LAN bus. The CDBR-2 (model 2) provides two analoginterface
connections, each of which can support either a four wire analog handsetor two wire data for direct
connection of a fax machine or modem Additionally, the CDBR-2 provides a separateinterface for
connectionof adigital handset.
Di2ital Handset: Thetelephonehandsetshavebeenselectedfor performanceandreliability. The handsets
contain noise-cancelingmicrophonesto overco~ the aircraft noise environment; audio is digitized at the
handsetto further ensureclear communication. Special function keys and a liquid crystal display allow
easy use of all options available to the user. The digital handsetsare offered with varied mounting
provisions to fit any installation requirement. Handsetsareoffered with a) a standardbuild-in style mount
to hold the handsetwhen not in use,with a ratcheting cord reel, b) that version with a bulkhead mounting
adapter,c) the handsetand cord reel without a mount, for custom mounting, and d) a "curly-cord" (like
standardoffice phones)with aplug for the ability to relocatethe handsetto various locationswired with the
matchingjack. Variations a - c also are available with the RJ-ll jack remoted from the handset,to be
locatedwhere it best fits in the interior design of the aircraft. All variations come in four colors: white,
platinum, pepperdust,andblack. Develop~nt is on-going for additional telephonehandsetoptions.
AllJ.: The AIU canbe usedto connectananalog SATCOM unit, a Cel1PhoneInterface(CPI), a HF radio,
or a Public Address(PA) amplifier, and/or other communications devicesto the MagnaStarsystem The
AIU bas been designed with electrical interfaces to optimize the connection to any analog-interface
SATCOM systemselectedby the custo~. Separateconnectionsareprovided to accotmtfor variations in
audio-line impedanceandlevel andin the hook switch and statusinterfacesbetweenSATCOM equip~nt.
HF radio connections can be made directly or through the aircraft audio control panel. The varying
requirementsfor the SATCOM and HF interfacesled to anAIU designthat offers the flexibility to connect
a wide variety of equip~nt andsystemsto the C-2000. AIUs interface to the ARTU over the LAN, like

~: 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-quietedcabins of businessjets, the ambient
noise canmake it difficult to hearthe electronic ringer of the standardhandset. Increasingthe volume of
the handsetspeakercould be annoying should the handsetbecloseto a user's ear when it rang. A separate
alerteravoidsthis problem andallows for installation of the handsetsin enclosedcompartments.) Singleor
multiple switches can be assignedto a handsetand to multiple handsets;and the cadenceof the "ring"
pattern canbe controlled, giving a great deal of flexibility to customize uplink call notification. OneCAS
is usedper aircraft; it connectsto a digital handsetport of any of the CDBRs in the system. The CAS may
also be usedto signal when Air-Ground, SATCOM or HF services are available or when one or more
particular handsetsarein use.
Miscellaneous: The MagnaStarsystemcan interfaceto many othercommunications equipment. The
"-802" modification to the ARTU provides a CEPT-EI interfaceto connectdirectly to SATCOM systems
or to cabin managementequipment. The flexibility is built in to the system to accommodatecustomer-
uniquerequirementswith 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
designedfor installation in pressurizedor non-pressurizedlocations. The mounting tray provides an
air plenum and fan for cooling. The fan is quiet enoughto allow cabin installation. The duplexer
canbe mountedin any convenientlocation betweenthe ARTU andthe antenna. The antennacomes
with a standardsix 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.

f) Measure cable RF loss at 900 MHz if test equipment is available.
Note: The total RF cable path loss from the ARTU to the ANTENNA should not exceed 3 dB. The two
different RF paths include the combination of the Antenna and Receive cables or the Antenna and
Transmit cables. The lengths of the RF cables are limited by this requirement.
Aircraft Power Cable
Priorto installation of the ARTU. verify the power cable installation for proper interconnection and correct
voltages. Calculate the voltage drop based on wire gauge and rated system current. Required check list
for this cable is:
POWERCABLE CHECK LIST
a) Visuallyinspectcablefor bentor damagedpins.
b) Continuitycheckfor properpin-to-pininterconnectionbetweencableconnectors.
c) Checkfor opencircuitconditionbetweeneach pin andthe backshell.
d) Checkfor opencircuitconditionbetweeneach pin andall otherconnectorpins.
e) Apply aircraftpowerto the PowerCable. Checkfor correctvoltageon the properpins.
f) Checkfor groundconnectionon the properpins.
g) Checkfor the absenceof groundor aircraftpoweron all otherconnectorpins.
RJ-11 Cables
Prior to installationof a FAXor Modemto a Handset.checkthe RJ-11cablefor properinterconnection. A
requiredchecklistfor this cableis:
a) Visuallyinspectcablefor bentor damagedpins.
b) Continuitycheckfor properpin-to-pininterconnectionbetweencableconnectors.
c) Checkfor open circuitconditionbetweeneach pin and all otherconnectorpins.
MagnaStar Maintenance Terminal (MMTCable)
Note: Do not permanently connect the MMT cable to the ARTU. This connector port is for
checkout and troubleshooting only. For normal operation, disconnect the MMTcable and replace
the dust cover on the ARTU MMTconnector.
With the MMT cable connected. after power up. the ARTU will not start running its operational software
until instructed to do so by the MMT unit.

Aftercablecheck-out.the aircraftis readyfor the installationof the MagnaStarC-2000
equipment. The followingcheck-outmust befollowed priorto applicationof aircraftpower.
ANTENNA
a) The Antennashould bemountedto a paintfree metalgroundedsurface. Ensurethat
the screw contact(countersink)surfaceof theAntennais free of paint. The screw
threadsmustmake metalliccontactto the groundplane. The groundplanemust
extendat leastonefoot radiallyfrom theAntenna.
b) After installingthe Antenna,measurethe DC resistancebetweenthe Antennaandthe
airframe. Bondingresistancemust be less than 2.5 milliohms.
c) Checkthatthe antennacableto Antennaconnectionis mechanicallysecure.
d) Ensurethat the minimumdistancebetweenthe C-2000 antennaand any antennafor
equipmentoperatinginthe 800 Mhzto 1200Mhzfrequencyband(e.g.DME,
Transponder.TCAS)shall be 3 feet. minimum. The minimumdistancebetweenthe
C-2000and any otherantennashall be two feet.
e) It should be notedthat the MagnaStarsystem is a line of sightsystemthat operates
with equipmentlocatedon the ground. The MagnaStarantennashould not be located
in positionthat will be blockedby other mechanicaldevicesin close proximityor easily
shadowedwhenthe aircraftmaneuversduringflight.
5.1.2 DUPLEXER
a) After installingthe duplexer.measurethe DC resistancebetweenthe duplexerand
the airframe. Bondingresistancemust be lessthan 2.5 milliohms.
b) Checkthe antennacable.transmitcable.and receivecable connectionsto the
duplexer.
These connectionsmust be mechanicallysecureso they will not becomeloose
duringaircraft
vibration. The SMAconnectors(transmitand receiveconnectors)should be
tightenedto 7
in-ibsof torque if usinga 620317-1duplexer.
ARTU MOUNTINGTRAY
a) After ARTU MountingTray installation.measureDC resistancebetweenthe ARTU
Mounting
Tray andthe airframe. Resistancemust be lessthan 2.5 milliohms.
b) Checkthe input and exit airflowpathsfrom the fan in the ARTU MountingTray.
Airflowpaths
mustbe clearof any obstructionsthat could restrictcooling.
