Welcome!

Dear Valued Customer,

All of us at L-3 Aviation Recorders take this opportunity to say “thank you” for your selection of the L-3

Airbus Iridium Satellite Communication (SATCOM) system.

This SATCOM system, also identified as the Automated Flight Information & Reporting System (AFIRS),

is a multi-function voice and data communication system that provides a link between the aircraft and

ground using the existing Iridium satellite constellation. The system consists of:

 Satellite Data Unit (SDU)

 SDU Configuration Module (SCM), which houses the system SIM card

 Iridium Antenna

 Coaxial Cable

These system elements are described in further detail in the following sections of this Welcome Kit

package. The system performs the following primary functions:

Satellite Phone

The Iridium SATCOM System contains a single-channel Iridium satellite phone along with an internal

Private Branch Exchange (PBX) system. The AFIRS 228 SDU includes telecom functions integrated into

the cockpit audio system for the flight crew and separate calling capability through conventional two-wire

“tip and ring” telephony devices. Cockpit dialing and control functions can be performed by using the

aircraft's Multipurpose Control Display Units (MCDUs). Up to two wired or eight cordless handsets can be

added in the cabin for intercom, call transfer, conference calling, camp-on calling and noise-cancelling

features. The aircraft can call or be called from any conventional telephone, as well as any other similarly-

equipped aircraft. This provides the crew with worldwide access to MedLink or other emergency medical

services.

ACARS Satellite Data Unit

For ACARS-equipped aircraft, the Iridium SATCOM System can function as a standard ARINC

741/761 Satellite Data Unit (SDU) when interfaced to the aircraft's ACARS Communication Management

Unit (CMU). The system uses a dedicated Iridium satellite channel for data services. The Iridium SATCOM

System receives messages from the CMU, prioritizes the messages, and transmits them over the Iridium

satellite link. ACARS messages received from the satellite link are routed to the CMU for processing.

Electronic Flight Bag (EFB) Interface

If desired, the Iridium SATCOM System SDU provides an EFB with an interface to the EFB message

transport system. An Ethernet port provides the physical connection between the devices – using industry

standard IEEE 802.3 LAN technologies. Once physically connected, the SDU routes to the EFB a web-

based portal that can be accessed by EFB applications using a defined IP based protocol, supporting text

messaging and other functions.

Iridium SIM Card Registration

The Iridium network is based on the international Global System for Mobile

communications (GSM) standard and architecture. With any GSM cellular device, all Iridium

transceivers capable of voice require a Subscriber Identity Module (SIM) associated with the

mobile device. Though the SIM can be used for many functions, such as restricting call access or

to store information, its primary function is to assign the telephone number to the L-3 Satellite

Data Unit (SDU) transceiver. An exception is the Iridium Short Burst Data (SBD) modem, which

operates solely from an IMEI number assigned to each modem.

Often customers or installers are not familiar with the need to activate the SIM and IMEI

for service over the Iridium network prior to testing or use of the system. You may select any

valid Iridium Service provider. Our recommendation is to contact our partner, FLYHT Aerospace

Solutions Ltd., complete the following activation form, and send to FLYHT for processing.

There are two types of voice service plans to choose from:

• Air Traffic Service (ATS)

The operator will be able to prioritize calls to and from the cockpit and pre-empt

a lower priority call with a higher priority incoming call. The calls from ground-to-

air have additional security procedures; the user will be required to have a User

ID, PIN, plane ID, and set the call priority.

• Non-ATS

This service does not have call prioritization and the ground-to-air calls only

require the phone number of the SIM card to place a call.

You may need the following information when activating a SIM card:

• Tail Number

• IMEI Voice Modem Number

• Avionics MFR – L-3/FLYHT

• IMEI Data Modem Number

• Avionics Model - AFIRS 228S Satellite Data Unit

• Voice Modem Model 9523

• Data Modem Model 9602

2. DESCRIPTION AND OPERATION

This section describes the system operation and architecture.

2.1 System Overview

The Airbus Iridium SATCOM System provides multiple voice and data communications functions in

the aircraft. The Automated Flight Information Reporting System (AFIRS) provides a satellite voice

and data communications (SATCOM) link with the Public Switched Telephone Network (PSTN) via

the Iridium® satellite network. The system uses a standard ARINC 741/761 SATCOM interface to the

flight crew’s Audio Integrating System and ARINC 739A Multi-Purpose Control and Display Units

(MCDUs) in the cockpit, as well as providing 3-extension Public Branch Exchange (PBX) capability for

up to 2 handsets in the cabin.

Figure 2-1 – Airbus Iridium SATCOM System Operational Concept

The Airbus Iridium SATCOM System provides a dedicated safety-services data channel with the

capability to send and receive standard ACARS messages between the aircraft’s Air Traffic Service

Unit (ATSU) and a safety-services certified terrestrial service provider.

2.2 System Architecture

The Airbus Iridium SATCOM System consists of modular avionics components that can be tailored to

meet customer needs. The core system components are the Satellite Data Unit (SDU), the SDU

Configuration Module (SCM), and the Iridium Antenna (see Figure 2-2). Optional components include

Cabin Handset(s) (Wired or Cordless).

This interface consists of a Microphone Input to the SDU and an Interphone Output from the SDU

to connect to a standard (DO-214) Audio Integrating System (e.g. Audio Panel) in the aircraft.

Software selectable discrete inputs and outputs can be configured to support this interface (e.g.

Mic On, Chime, Chime Reset, End Call functions).

 ARINC 429 Transmitters (6) and Receivers (16)

These interfaces can be software-configured to connect to various aircraft systems to support both

the display and control functions of the Airbus Iridium SATCOM System. Typical interfaced

systems include MCDUs, ACARS ATSUs, Airbus Centralized Fault Display Systems (CFDS), etc.

Page 19

 RS-232/422 Serial Ports (4)

These interfaces can be software-configured to connect to different aircraft systems. Typical

interfaced systems include EFB, Global Positioning System (GPS), etc.

 Ethernet Ports (4)

These interfaces can be used to connect to several different systems. Typical interfaced systems

include EFB, CFDS, etc. One of these ports can also be used to provide a remote maintenance

port interface (e.g. in the flight compartment).

 Discrete Outputs (8) and Inputs (16)

Discrete inputs and outputs can be used to provide or supplement various flight crew control and

display interactions, particularly for voice functions. Discrete inputs can also be used to determine

the states of various aircraft systems when this information is not available on a databus (e.g.

Weight-on-Wheels, Doors Closed, etc.).

 Iridium Antenna (1)

An antenna mounted on the top of the fuselage is used to communicate with both the Iridium

satellite network and the GPS satellite network.

 User Media Interfaces – SIM (1), CF (1)

There are two types of media available for the user to insert or remove from the Airbus Iridium

SATCOM System. The SCM contains a user accessible Subscriber Identity Module (SIM) card

slot for storage of the Iridium communications management information. The SDU contains a

front panel accessible Compact Flash (CF).

 Maintenance Interfaces – Ethernet (1)

An RJ45 jack on the front panel provides Maintenance Port access using an Ethernet connection.

standard ARINC 600 mounting tray. Figure 4-1 shows a typical ARINC 600 2MCU tray used for the

SDU.

Figure 4-1 – 2MCU Mounting Tray

While the SDU does not require forced-air cooling, every attempt should be made to place the SDU in

a benign and well-ventilated environment. Placing the SDU on a plenum shelf in the Electronics Bay

of the aircraft and using a mounting tray that provides cooling air to the SDU is preferred.

The SDU tray should be electrically bonded to the airframe (<20 milliohms). It is recommended that

the SDU be located where easy front panel access is available to facilitate replacing the flash card or

connecting to the Maintenance Port.

4.2 SDU Configuration Module (SCM)

The SCM can be mounted on or near the SDU tray within 24 inches of the SDU rear connector. The

SCM should be electrically bonded to the airframe (<20 milliohms). It is recommended that the SCM

be located to provide easy access to the cover if ever the SIM card requires replacement. Refer to

Figure 3-4 for the SCM mounting footprint.

4.3 Iridium Antenna System

The Airbus Iridium SATCOM System has a single combined Iridium/GPS RF connection on the rear

interface connector, which is to be connected to a single combined Iridium/GPS Antenna. The

antenna system is comprised of all the components from the rear interface connector up to and

including the antenna. The total gain of the antenna system must be greater than 0 dB at 1626.5 MHz

(measured at the antenna zenith).

Most Iridium antennas have a gain of +3 dBic at the zenith; therefore the maximum attenuation in the

rest of the antenna system must be less than 3 dB. If an antenna with a different gain is selected, the

maximum loss of the rest of the antenna system must be adjusted accordingly.

4.3.1 Antenna

Iridium SATCOM System Antenna: This is a passive antenna designed to cover the frequency range

from 1565 MHz to 1626.5 MHz for Iridium transmit / receive operations and GPS reception. It is a

6. SYSTEM INTERFACE WIRING

This section provides information on the system interface wiring required for the Airbus Iridium

SATCOM System.

6.1 General

All wire types and installation practices must comply with the requirements for the aircraft. Unless

otherwise noted, minimum wire size is 22 AWG for standard copper wire or 24 AWG for high strength

copper alloy wire.

Terminate all shields at ground block or ground stud on SDU tray. Keep shield drains and unshielded

conductor lengths as short as practicable (<3”).

6.2 Primary Power, Antenna, and SCM

The primary power, antenna, and SCM connections shown in Figure 6-1 are required for all Airbus

Iridium SATCOM System installations. The system will start and continue to operate whenever power

(20.5 – 32.2 VDC) is available at the Primary Power Input pin (J1C-2).

Figure 6-1 – Primary Power, Antenna, and SCM Interface

6.3 ARINC 429 Interfaces

The Airbus Iridium SATCOM System has 16 ARINC 429 receive ports and 6 ARINC 429 transmit

ports. Each port is software-configurable for high or low speed, and the receive ports are also

individually software-configurable for odd, even or no parity checking. The transmit ports always

transmit odd parity.

Page 43

6.3.1 Receiver Protocols

Each of the ARINC 429 receivers can be configured in software for the proper protocol of the external

aircraft system to which it is interfaced. Below is a list of the available ARINC 429 receiver protocols.

(See §3.8 for the label specifications for each receiver protocol.) Once a protocol (except “None” is

selected for any given receive port, it is no longer available for assignment to any of the other ports.

 None

 ACARS 1

 ACARS 2

 Airbus CFDS

 A739 MCDU 1

 A739 MCDU 2

 A739 MCDU 3

When an input is not connected to an active system (e.g. no connection, or wiring provisions only are

installed), the port should be configured as “None” to avoid triggering bus inactivity faults.

6.3.2 Transmitter Protocols

Each of the ARINC 429 transmitters can be configured in software for the proper protocol of the

external aircraft system to which it is interfaced. Below is a list of the available ARINC 429 transmitter

protocols. (See §3.10 for the label specifications for each transmitter protocol.) Once a protocol

(except “None”) is selected for any given port, it is no longer available for assignment to any of the

other ports.

 None

 ACARS

 A739 MCDU

 Airbus CFDS

6.5 ACARS ATSU

The ACARS ARINC 429 Tx interface provides safety-services data functionality for the Airbus Iridium

SATCOM System. It is recommended that if the ACARS ATSU ARINC 429 Rx connection will not be

utilized, that the wires be capped and stowed near the connectors as shown. ARINC 429 Rx port 4 is

shown in Figure 6-3, but any Rx port from 2 to 16 may be used.

6.6 CFDIU Interface

The SDU communicates with the Airbus Centralized Fault Display Interface Unit (CFDIU) over

two ARINC 429 Low Speed busses, (1) input and (1) output as shown in Figure 6-4.

Figure 6-4 – CFDIU Interface

6.7 Date, Time and Position

The Airbus Iridium SATCOM System uses date, time and position information for numerous purposes,

including information tags attached to various reports and events. Date, time and position information

is provided by the system’s internal GPS.

6.8 RS-232/422 Databus

The Airbus Iridium SATCOM System has four serial ports (transmit and receive). Each port is

software-configurable for RS-232 or RS-422 mode. The speed, data bits, parity, stop bits, and flow

control settings for each port are also software-configurable. See Figure 6-5.

Each serial port is assigned 5 pins on the rear connector. The function of these pins is dependent on

whether RS-232 or RS-422 mode is being used.

Table 6-1 – Serial Port Pin Assignments

Page 47

When configured for RS-232 mode, the serial ports support software (Xon/Xoff) and hardware

(RTS/CTS) handshaking. If hardware handshaking is not being used, the RTS and CTS pins do not

need to be connected.

Figure 6-5 – Serial Port Interface

6.9 Ethernet

The Airbus Iridium SATCOM System has four Ethernet ports (see Figure 6-6). Each port can auto-

negotiate the best speed (10/100) and mode (full/half duplex). Port 1A is currently configured with a

static IP address.

A 4-conductor Ethernet cable must be used. The rear connector pin layout provides slightly better

noise immunity with a star-quad cable construction, but a twisted-pair cable construction can generally

also be used. For star-quad cables, the conductor lay order should be maintained without crossing the

conductors when terminating. For twisted-pair construction, the conductor twists should be maintained

right up to the rear connector. In either case, the best noise immunity is obtained by keeping the strip

length of the shield as short as physically possible, preferably <0.25 inches.

PIC P/N E51424 and ECS P/N 422404 are examples of aircraft-quality star-quad Ethernet cables that

are typically suitable for use. PIC P/N E40424 and ECS P/N 922404 are examples of aircraft-quality

twisted-pair Ethernet cables that are typically suitable for use.

Each of the Ethernet ports can be configured in software for the proper protocol of the external aircraft

system to which it is interfaced. Below is a list of the available protocols.

 None

 Not Monitored

Airbus Iridium SATCOM System

165E5733-00 L-3 Aviation Recorders Proprietary

Issue, Rev. 02

21 January 2014

Page 48

 Monitored

Unused Ethernet ports should be configured as “None.” A “Monitored” port is one where the system

expects an active link and it will generate a fault if the Ethernet link to the external system is not

available. For example, if the SDU is connected by Ethernet to a Class 2 EFB that is routinely turned

off and stowed for take-off and landing, the port should be configured as “Not Monitored” or the

system will generate a fault whenever the EFB is disconnected.

Figure 6-6 – Ethernet Interface

6.10 Discrete Inputs

The Airbus Iridium SATCOM System has 16 Discrete Inputs, of which 14 are software-configurable for

Open-Ground or Open-28V signaling levels, Active High or Active Low logic, and the assigned

function.

6.10.1 Landing Gear Control Interface Unit (LGCIU) Input

Discrete Input No. 1 (Din 1) is dedicated for use as a Landing Gear Control Interface Unit (LGCIU1)

input. When there is only one LGCIU input (i.e. the LGCIU2 function is not assigned to a Discrete

Input; see §6.10.2) and the ‘LGCIU1’ input transitions to the active state, the system is signaled that

the aircraft is on the ground, and the inactive state indicates that the aircraft is in the air.

LGCIU1 (Din 1) is only an Open-Ground input; it cannot be configured as an Open-28V input. A

Hardware Programming Pin (HPP) is provided to set whether the LGCIU1 input is Active High or

Active Low. If the LGCIU HPP pin (J1B-11F) is tied low, LGCIU1 is configured as an Active Low input,

i.e. Ground = On Ground. If the LGCIU HPP pin is connected to ground, LGCIU1 is configured as an

Active High input, i.e. Ground = In Air.

If one of the configurable Discrete Inputs is configured for the LGCIU2 function (see §6.10.2), the

following logic is used to determine the aircraft’s Air-Ground status:

 When the ‘LGCIU1’ discrete input is in the active state (as configured by the LGCIU HPP

strapping) and the ‘LGCIU2’ discrete input is in the active state (as defined by the ICT setting

for the discrete input configured as ‘LGCIU 2’), the aircraft is considered as ‘on the ground.’

Airbus Iridium SATCOM System

165E5733-00 L-3 Aviation Recorders Proprietary

Issue, Rev. 02

21 January 2014

Page 49

 When any of the LGCIU discrete inputs are in the inactive state, the aircraft is considered as

‘in the air.

6.10.2 Function Assignment

The discrete inputs are software configurable. Once a function is selected for any given input, it is no

longer available for assignment to any of the other inputs. See Figure 6-7.

The ‘Mic On’, and ‘Call Light’ functions are used in conjunction with the Extension 1 audio interface

and are discussed in §6.12.1.1 below.

Discrete Input No. 1 (Din 1) is dedicated as a LGCIU input. Only Discrete Inputs Din 2 through Din 15

are software-configurable. Discrete Input No. 16 (Din 16) is dedicated as “aircraft on ground” (LGCIU

HPP).

None

When an input is not connected to an active system (e.g. no connection, or wiring provisions

only are installed), the input should be configured as “None.”

System Reset

The System Reset Discrete Input, when configured, will reset the system only after an inactive

to active transition. The system will reset only once even if the discrete input is left active. The

System Reset function is independent of the 'In-Air' or 'On-Ground' status of the aircraft.

Landing Gear Control Interface Unit 2 (LGCIU2)

A second Landing Gear Control Interface Unit input may optionally be provided to the AFIRS

system. Refer to §6.10.1 for the logic used when a ‘LGCIU2’ input is provided.

Figure 6-7 – Discrete Input Interfaces

6.11 Discrete Outputs

The Airbus Iridium SATCOM System has 8 configurable Discrete Outputs, each of which is software-

configurable for Active High or Active Low logic and the assigned function. The Discrete Outputs use

‘Open-Closed’ signal levels, where the output is either high-impedance to ground (Open) or low-

impedance to ground (Closed).

Once a function (except “None”) is selected for any given output, it is no longer available for

assignment to any of the other outputs.

6.12 SATCOM

This section describes the interface and integration requirements for the Airbus Iridium SATCOM

System with an Audio Integrating System.

6.12.1 Audio Integrating System

Extension 1 is generally intended to be connected to the aircraft’s audio integrating system for flight

crew use. The interfaces required to fully support this functionality vary significantly depending on the

design of the audio integrating system. Generally, the MCDUs are used for control and display of the

SATCOM functions for Extension 1.

6.12.1.1 Audio Discrete Signals

There is one discrete input and one discrete output that can be used to support the integrated audio

interface.

Airbus Iridium SATCOM System

165E5733-00 L-3 Aviation Recorders Proprietary

Issue, Rev. 02

21 January 2014

Page 51

Mic On Input

The ‘Mic On’ function is dedicated as a ‘Latched ACP’ mode; therefore, Voice Extension 1

(Mic/Phone input) will answer an incoming call when the ‘Mic On’ input transitions to the active

state. Once a call is in progress, the microphone audio channel will function as long as the

‘Mic On’ input is in the active state. If a call is in progress and the ‘Mic On’ input toggles to the

inactive state, the call will be terminated. For outgoing calls when the ‘Mic On’ input is

configured for ‘Latched ACP’, the function is dependent on which control source is configured

for Extension 1. When an MCDU is the Extension 1 dialing control, setting the ‘Mic On’ input to

the active state will initiate the dialing process using the phone number preselected on the

MCDU.

Call Light Output

The ‘Call Light’ output is software configurable for either steady or flashing lights. When an

incoming voice call is ringing, the ‘Call Light’ output will transition to the active state; either in a

steady state or flashing at approximately a 1 Hz rate. When the incoming call is subsequently

answered, the ‘Call Light’ output will remain active in the steady state as long as the call is in

progress. When the call in progress is terminated, the ‘Call Light’ output will go inactive.

6.12.1.2 Latched ACP Configuration

If the Audio Integrating System provides a latched Mic On output, the following interface can be used.

When an incoming call is ringing and the SATCOM switch on the Audio Control Panel is pressed, the

call will be answered and microphone audio will always be live. The SATCOM switch on the Audio

Control Panel is pressed a second time to end the call. Calls cannot be answered and terminated on

the MCDU screen in this configuration.

The following diagram also shows how the Call Light output can be interfaced to an Audio Integrating

System that provides SATCOM visual and aural call indications. In this case, a Call Light, Chime and

Chime Reset switch are not required. See Figure 6-8.

7.1 Accessing the Maintenance User Interface (MUI)

You access the AFIRS MUI by connecting an Ethernet cable to the Maintenance Port of the SDU.

Alternatively, as described in section 6.9, Ethernet Port 1A can be used.

Also, if an Electronic Flight Bag (EFB) with a supported web browser installed is connected to one of

the rear Ethernet port connections, the EFB can be used as an AFIRS maintenance terminal and a

laptop is not required.

To access the Maintenance User Interface (MUI):

1. Connect an Ethernet cable either to the Maintenance Port via the front panel access door of

the SDU or through the rear Ethernet Port 1A connection. Note that the Airbus Iridium

SATCOM System power may be on or off.

2. Connect the other end of the Ethernet cable to a laptop that is running a web browser.

Note:

It is recommended to use Mozilla Firefox ® as the Internet browser with the SDU. The laptop

network adapter must be set to the same subnet mask as the SDU (i.e. 255.255.255.0).

3. If not already powered, apply power to the SDU.

4. Confirm that the green link light (adjacent to Maintenance Port RJ45 connector) is illuminated,

either steady or flashing (a flashing link light indicates that data is being transmitted).

5. Open a web browser on the laptop. In the Address bar, type one of the two following IP

addresses depending on the connection point:

192.168.128.1 (if connecting to the Maintenance Port at the front panel of the SDU –

see Figure 7-1.)

10.0.0.238 (if connecting to the rear Ethernet Port 1A. – see Figure 6-6).

AIRBUS IRIDIUM SATCOM SYSTEM

GENERAL

This product and related documentation must be reviewed for familiarization with safety markings

and instructions before operation.

This instrument was constructed in an ESD (electro–static discharge) protected environment. This is be

cause most of the semiconductor devices used in this instrument are susceptible to damage by static dis

charge.

Depending on the magnitude of the charge, device substrates can be punctured or destroyed by contact or

mere proximity of a static charge. The results can cause degradation of device performance, early failure,

or immediate destruction.

These charges are generated in numerous ways such as simple contact, separation of materials, and nor

mal motions of persons working with static sensitive devices.

When handling or servicing equipment containing static sensitive devices, adequate precautions must be

taken to prevent device damage or destruction.

Only those who are thoroughly familiar with industry accepted techniques for handling static sensitive de

vices should attempt to service circuitry with these devices.

In all instances, measures must be taken to prevent static charge build–up on work surfaces and persons

handling the devices.

BEFORE APPLYING POWER

Verify that the product is set to match the available line voltage and the correct fuse is installed.

Servicing instructions are for use by service–trained personnel only. To avoid dangerous electric shock, do

not perform any servicing unless qualified to do so.

Adjustments described in the manual are performed with power supplied to the instrument while protective

covers are removed. Energy available at many points may, if contacted, result in personal injury.

4. MAINTENANCE PHILOSOPHY

The Model Airbus Iridium SATCOM System line replaceable units (LRUs), consisting of the

SDU and SCM, are considered “ON CONDITION LRUs” and are designed as

maintenance-free units. The SDU and SCM are considered Level-1 maintenance units and

are not field-repairable.

The bench testing and repair of circuit card assemblies (CCAs) containing surface mount

technology (SMT) devices require specialized factory equipment, training, and techniques.

These assemblies are not field-repairable while the unit is under the warranty period. As a

result, during the unit’s warranty period, the Airbus Iridium SATCOM System maintenance

philosophy is replacement of failed LRU. If an LRU failure occurs, the LRU is to be

returned to L-3Com for testing, fault isolation, and repair.

The L-3Com Repair Station has been given authority to repair, modify, and bench test for

return to service all Airbus Iridium SATCOM System LRUs using L-3Com Factory ATP

procedures. Repair, modification, and/or recertification of Airbus Iridium SATCOM System

LRUs as per ATP procedure are limited to the L-3Com Repair Station.

In turn, the operator will receive a certified Return-To-Service unit to be reinstalled into the

aircraft or as a replacement for a spare unit. Attempts to repair any components of the

Airbus Iridium SATCOM System or the LRU will void the warranty.

Refer to the Airbus Iridium SATCOM System Installation manual, p/n: 165E5733-00 for

detailed instructions for on-aircraft installation, removal and operation.

DESCRIPTION AND OPERATION

1. SYSTEM OVERVIEW

Refer to Figure 1. The Airbus Iridium SATCOM System comprises a portion of the aircraft

avionics, or “Aircraft Earth Station” (AES) required to support the "Next Generation

Satellite System" (NGSS) using the Iridium Satellite System as specified in RTCA/DO-

262A.

This system serves as the radio transceiver that provides RF path connectivity with the

satellite(s), and provides the digital data (ISDM) and/or analog voice and/or digital voice

interfaces (ISVM) with other aircraft user subsystems. Its primary functions are: modulation

and demodulation of transmitted and received signals, respectively, signaling and protocol

interactions with corresponding satellites, channel management, and switching and

interconnections with the aircraft and their attached avionics.

The Airbus Iridium SATCOM System provides multiple voice and data communications

functions in the aircraft. The Automated Flight Information Reporting System (AFIRS)

provides a satellite voice and data communications (SATCOM) link with the Public

Switched Telephone Network (PSTN) via the Iridium® satellite network. The system uses a

standard ARINC 741/761 SATCOM interface to the flight crew’s Audio Integrating System

and ARINC 739A Multi-Purpose Control and Display Units (MCDUs) in the cockpit, as well

as providing 3-extension Public Branch Exchange (PBX) capability for up to 2 handsets in

the cabin.

2. SYSTEM ARCHITECTURE

The Airbus Iridium SATCOM System consists of three Line Replaceable Units (LRUs). The

core system components are the Satellite Data Unit (SDU), the SDU Configuration Module

(SCM), the Iridium Antenna, and Coaxial Antenna Cable assembly. Optional components

include Cabin Handset(s) (Wired or Cordless).

A. SATELLITE DATA UNIT (SDU)

Refer to Figure 3. The SDU is an ARINC 600 2MCU electronic enclosure that resides

in the aircraft’s equipment rack. It contains the system intelligence and interface

circuitry for connecting to the various aircraft systems. The SDU also contains Iridium

voice and data modem(s), as well as a GPS receiver.

C. IRIDIUM ANTENNA SYSTEM

Refer to Figure 5. The antenna is a Commercial Off-The-Shelf (COTS) unit that is

mounted on the top of the aircraft’s fuselage. It provides satellite connectivity for both

the GPS and Iridium satellite systems.

The Airbus Iridium SATCOM System has a single combined Iridium/GPS RF

connection on the rear interface connector, which is to be connected to a single

combined Iridium/GPS Antenna. The antenna system is comprised of all the

components from the rear interface connector up to, and including, the antenna. The

total gain of the antenna system must be greater than 0 dB at 1626.5 MHz (measured

at the antenna zenith).

Most Iridium antennas have a gain of +3 dBic at the zenith, therefore, the maximum

attenuation in the rest of the antenna system must be less than 3 dB. If an antenna

with a different gain is selected, the maximum loss of the rest of the antenna system

must be adjusted accordingly.

REPAIR

1. GENERAL

This section is intended to contain information required to restore a worn or damaged part

to a serviceable condition. However, the Airbus Iridium SATCOM System is a completely

solid-state device that does not contain any electro-mechanical moving parts.

The Airbus Iridium SATCOM System consists of a Satellite Data Unit (SDU) and SDU

Configuration Module (SCM) line replaceable units (LRUs).

These LRUs have been designed as Level-1 maintenance units that make extensive use

of surface mount technology (SMT). The repair of circuit card assemblies (CCAs)

containing SMT components requires specialized factory equipment, training, and

techniques, therefore, such CCAs are not field-repairable. Only the L-3AR Repair Station,

FAA: LD7R612J; EASA.145.4620 is authorized to repair the Airbus Iridium SATCOM

System components in accordance with L-3AR Factory test, calibration and repair

specifications.

CAUTION: THE AIRBUS IRIDIUM SYSTEM CIRCUIT BOARDS ARE SUSCEPTIBLE

TO ELECTROSTATIC DESTRUCTION. PRIOR TO HANDLING PWAs,

ENSURE PROPER PERSONNEL GROUNDING TECHNIQUES ARE

USED.

ENSURE THAT CARDS ARE PLACED INTO STATIC SHIELDING

CONDUCTIVE BAGS WHEN HANDLING OR STORING.
