AUDIO MANAGEMENT UNIT
Communication and navigation systems are connected to
the AMU for analog inputs and to the RMP for frequency
selection.
The audio management unit (AMU) ensures the interface
between the user (jack panel and ACP) and the various
radio communication and radio navigation systems.
It also serves to record communications (CAA recording)
and is equipped with a TEST circuit (BITE). This TEST
circuit enables the AMU to be connected to the CFDIU.
The AMU ensures the following functions:
- Transmission
- Reception
- SELCAL and display of ground crew and Cabin
Attendant calls
- Flight interphone
- Emergency function for the Captain and First
Officer stations.
RADIO MANAGEMENT PANEL
The radio management panels (RMP) centralize radio
communication frequency control.
RMP 1 and RMP 2 can also serve as backups for the
flight management and guidance computers (FMGC) for
radio navigation frequency control (VOR, DME, ILS,
ADF).
The aircraft is equipped with three RMPs which are
identical and interchangeable.
The 3rd RMP is optional.

RADIO MANAGEMENT PANEL PRESENTATION
RADIO MANAGEMENT PANEL (RMP) DESCRIPTION
TRANSFER P/B
The RMPs are used for the selection of radio
communication frequencies. They are also used for the
standby selection of radio navigation frequencies in
back-up mode.
3 RMPs are used for frequency selection, each one can
control any VHF (HF) frequency.Only RMP1 and RMP2 can
be used for the standby selection of radio navigation
system frequencies in back-up mode.
The 3 RMPs permanently dialog so that each RMP is
informed of the last selection made on any of the other
RMPs. If two RMPs fail, the remaining RMP controls all
the VHF transceivers.
The transmission of data to the communication and
navigation systems and the dialog between the RMPs are
performed through ARINC 429 buses.
When the transfer key is pressed, the operational
frequency becomes the standby frequency, and the
standby frequency becomes the operational frequency.
TMUCOMB01-T01 LEVEL 1
UBQ4200
WINDOWS
There are 2 display windows:
- The active window displays the operational
frequency
- The standby/course window displays the standby
frequency or the course in back-up navigation
mode.
The windows are liquid crystal displays with a high
contrast.
COMMUNICATION KEYS
There are 5 pushbutton keys for the radio communication
systems, 3 of them are used for VHF. When a key is
pressed, the relevant active and the standby
frequencies are automatically displayed in the
dedicated windows.
SEL INDICATOR
The SEL indicator light comes on white, when a non
dedicated Radio Management Panel takes control of the
system frequency selection.
The normal configuration is:
- RMP1 allocated with VHF1
- RMP2 allocated with VHF2
- RMP3 allocated with VHF3 (HF1).
If VHF2 is selected on RMP1, the SEL light comes on
white on RMP1 and RMP2.
DUAL SELECTOR KNOB
The dual selector knob is used for the selection of
the frequency/course displayed in the standby/course
window.

RADIO MANAGEMENT PANEL INTERFACES
RADIO
FMGCs
RMP 1 and RMP 2 have two ARINC 429 data buses connected
to the radio communication transceivers:
- COM BUS 1 delivers the VHF 1 frequency,
- COM BUS 2 delivers the VHF 2 frequency.
Three dialog buses ensure exchange of information
between the three RMPs. Each RMP periodically transmits
its context on its dialog bus.
Each RMP can control any radio transceiver but is more
particularly dedicated to one system.
Basic allocation:
- RMP 1 → VHF 1
- RMP 2 → VHF 2
Possible allocation (depending on options):
- RMP 1 → VHF 1
- RMP 2 → VHF 2
- RMP 3 → HF 1
- ACARS → VHF 3
In normal operation, the navigation systems are tuned
automatically (or manually from the MCDUs) by the FMGCs
via internal relays of the onside RMPs. The RMP is
thus transparent to the onside FMGC.
In case of failure of one FMCG, the onside navigation
systems are tuned directly by the remaining FMGC.
CFDIU
The BITE functions of the system are available through
the CFDS.
LGCIUs
In order to increment the fault memories in case of
CFDIU failure, each RMP receives a discrete giving the
landing gear configuration.
RMP 1 receives this discrete from LGCIU 1, and RMP 2
and 3 from LGCIU 2.
NAVIGATION
TMUCOME01-T01 LEVEL 3
UBQ4200
RMP FAILURE
If the standby navigation mode is selected, the
navigation systems frequencies are controlled by RMP
1 and RMP 2 only. The standby navigation is selected
in the event of failure of both FMGCs.
In this condition :
- RMP1 controls VOR 1, ADF 1 and ILS 1 and 2.
- RMP2 controls VOR 2, ADF 2 and ILS 1 and 2.
- ILS 1 and 2 receivers always operate on the
same frequency which can be controlled from
any RMP, either directly or through the cross
talk bus.
EFFECTIVITY
EFFECTIVITY
ALL
The system architecture allows access to all
communication functions in case of failure of any RMP.
But, if RMP1 or RMP 2 fails, the onside navigation
systems are lost.
An RMP failure is indicated by the blanking of the
display windows. Should a failure occur, the failed
RMP has to be switched off. When selected off, the RMP
sends a discrete signal which enables system
reconfiguration.

The purpose of this topic is to study RMP operation
through an example.
The ON/OFF switch controls the power supply of the
RMP.
To select a new frequency for VHF 1, the VHF 1 key
must be pressed.
VHF1 light comes on as VHF 1 is selected.
NOTE :
The SEL light indicates selection of a radio system
by an other RMP than the RMP normally allocated to it.
For example, it will come on white in case of selection
of VHF 2 on RMP 1 or in case of selection of VHF 1 on
RMP 2. In this case, the SEL light also comes on on
the RMP to which the system is normally dedicated.
VHF1 is selected.
The ACTIVE window displays the current operating
frequency
for
VHF
1,
while
the
STBY/CRS
(standby/course) window displays the standby
frequency.
A new frequency is selected by rotating the two
concentric knobs below the STBY/CRS window and can be
activated by pressing the transfer key.
The frequency values have been interchanged. VHF1 now
operates on a new frequency.
On RMP1 and RMP2 only, the NAVigation guarded
pushbutton key allows the radio navigation systems to
be selected, in back-up mode only, when the Flight
Management and Guidance Computers (FMGCs) have failed.

HF TRANSCEIVER
AMU
The High Frequency (HF) system serves for all
long-distance voice communications between different
aircrafts in flight or on the ground, or between the
aircraft and one or several ground stations.
The HF system operates within the frequency range of
2.8 to 23.999 MHz with 1 KHz channels spacing between
channels.
The HF system is linked to the Audio Management Unit
for connection to the audio integrating and SELective
CALling (SELCAL) system.
The Audio Control Panels (ACPs) are used for HF
transmission or reception selection mode and control
of the received audio signal levels through the AMU.
LGCIU
RMPs
TMUCOMW04-T01 LEVEL 3
UBQ4200
The RMP controls the various operations which are
transmitted to the transceiver by anumeric message in
compliance with ARINC 429.
This message can be received by the port A or the port
B of the transceiver. The RMP performs the selection
by a discrete.
The message can be made up of a one word of 32 bits
or two words of 32 bits for the 100 Hz spacing or CW
mode. A microprocesseur performs the decoding of the
frequency and mode ( AM or USB ).
The microprocessor checks the message from the RMP and
controls the system operation. In case of failure it
controls the illumination of the lights located on the
face and/or acts on the transmitter.
The Landing Gear Control and Interface Unit indicates
the flight or ground aircraft status.
This information is used by the HF BITE, in order to
count the flight legs in case of CFDIU failure.
CFDS
For maintenance purposes, a Built In Test Equipment
is integrated in the HF transceiver.
The BITE functions of the HF transceiver are monitored
by the Centralized Fault Display System.

The selective calling system provides visual and aural
indication of calls received from ground stations
equipped with a coding device.
The ground station tone generator provides the assigned
aircraft code which modulates a VHF (or an HF)
transmitter.
In order to receive the SELCAL CALL, the same frequency
as on the ground must be activated in the aircraft.
SELCAL: SELective CALling system
This function is integrated in the AMU. The A/C code
can be set on the SELCAL code panel fitted in the
avionics bay.
TMUCOML01-T01 LEVEL 1
UBQ4200
SELCAL OPERATION
When a selcal call is received, the CALL light flashes
amber on the corresponding transmission key and a
buzzer sound is heard.
The buzzer signal is generated by the Flight Warning
Computer (FWC).
CALL flashes amber on all the ACPs when a selcal call
is received.
The CALL indication can be manually cleared by pressing
the RESET key on any ACP or it can be automatically
cleared upon transmission on the called channel.

SELCAL AND COCKPIT CALL SYSTEM D/O
GENERAL
The SELCAL and CALL functions are performed in the
Audio Management Unit (AMU) by the SELCAL/CALL card.
This card receives SELCAL calls from the ground
stations via the communication channels, a SELCAL code
from the SELCAL code panel, CALLs from the ground crew
and the attendant stations and provides visual and
aural warnings.
TMUCOM101-T01 LEVEL 3
UBQ4200
SELCAL OPERATION
The SELCAL/CALL card has 5 inputs connected to the
communication receiver SELCAL outputs. These inputs
are permanently scanned, and when a SELCAL signal is
present, a comparison is made with the code programmed
on the SELCAL code panel.
When the 2 codes agree, a message is sent to the various
ACPs, via the corresponding audio cards.
On the ACPs, the CALL light, corresponding to the
communication channel used, flashes amber.
At the same time, data is sent to the flight warning
computers (FWC). The FWCs send an audio call buzzer
to the loudspeakers.
The Call is cancelled using the RESET key on one ACP,
or selecting the called channel and activating the
PTT.

GROUND CALL
ATTENDANT CALL
Two types of calls may be received by the SELCAL/CALL
card :
- ground call and,
- cabin attendant call.
When the cockpit call pushbutton, located on the
external power control panel, is pressed, ground
information is sent to the SELCAL/CALL card and to the
FWC.
The FWC activates the buzzer signal and sends it to
the cockpit amplifiers in the AMU to be broadcast
through the loudspeakers.
The SELCAL card sends a signal through the various
audio cards to the ACPs.
The MECH legend flashes amber for 60 seconds on the
ACPs.
The visual call is automatically cancelled and the
circuit reinitialized after 60 seconds or when the
RESET pushbutton is pressed in, on any ACP.
The automatic reset may be cancelled with the AMU pin
programming.
When a call is made from a cabin attendant station,
the cabin intercommunication data system (CIDS)
generates ground information to the SELCAL/CALL card
and to the FWC.
During one second, the FWC activates the buzzer signal
and sends it to the cockpit amplifier in the AMU to
be broadcast through the loudspeakers.
The SELCAL/CALL card sends a signal through the various
audio cards to the ACPs.
The ATT legend flashes for 60 seconds on the ACPs.
The visual call is automatically cancelled and the
circuit reinitialized after 60 seconds or when the
RESET pushbutton is pressed in, on any ACP.
Information is also sent to the CIDS for
reinitialization.
The automatic reset may be cancelled with the AMU pin
programming.

FLIGHT INTERPHONE SYSTEM OPERATION
INT SELECTION
INT KEY and KNOB
The INT position of the INT/RAD selector switch enables
permanent use of the flight interphone without any
further action and whatever the radio key selected
(Here VHF 1).
This is a stable position.
The flight interphone can also be used like a VHF
transceiver. Selection of the INT transmission key
lights the green bars, indicating that the flight
interphone is ready to operate.
Pressing and releasing the INT reception knob enables
adjustment of the interphone level. If done, the knob
comes on white.
Placing and holding the INT/RAD switch in RAD position
enables the operator to talk through the flight
interphone system.
NOTE : The radio function has priority over the flight
interphone function.
So, even with the INT/RAD switch in INT
position, the flight interphone is momentarily
cut during a radio emission ( Radio key selected
and hand microphone or side-stick Push To Talk
actuated).
RAD SELECTION
TMUCOMN01-T01 LEVEL 3
UBQ4200
The RAD position of the INT/RAD selector switch puts
the preselected channel in
emission (Here VHF 1).
This is an unstable position.
This position acts like the selection of the hand
microphone pushbutton or like the Push To Talk
pushbutton of the side-stick.

ACARS SYSTEM PRESENTATION
GENERAL
The Aircraft Communication Adressing and Reporting
System enables exchange of data in digital form between
the aircraft and a ground station.
The Aircraft Communication Addressing and Reporting
System Management Unit(ACARS MU) provide the
management of the transmission to the ground of data
delivered by the different interfaces, and the
management of the reception, printing and display of
ground messages on the Multipurpose Control and Display
Unit(MCDU).
TMUACAA01-T01 LEVEL 1
UBQ4200
INTERFACES
The ACARS can be used by peripheral systems either
automatically or uppon crew request.
The ACARS management unit is linked to:
- the Data Management Unit (DMU) if installed,
- the Flight Management and Guidance Computers
1 and 2 (FMGCs) ,
- the Centralized Fault Display Interface Unit
(CFDIU),
- the VHF 3 transceiver,
- the Multipurpose Control and Display Units 1
and 2 (MCDUs),
- the printer.
EFFECTIVITY
EFFECTIVITY
ALL
The ACARS management unit is also linked to :
- the Flight Warning Computers 1 and 2 (FWCs),
- the System Data Acquisition Concentrator (SDAC)
- the Radio Management Panels (RMPs).
Some ACARS functions can be operated from the MCDU.
TRANSMISSION
The ACARS manage both emission and reception of data.
The radio transmission/reception of messages is done
through the VHF 3 transceiver.
A ground network transmits data from the ground
receiver to the airline main base.
NOTE: The crew can at any time take the control of the
VHF3 to perform voice communication.
AIRLINE APPLICATION
The ACARS applications are dedicated to maintenance
and engineering operations and also to crew operations
and information.
The ACARS application depends on operational programs
defined by each company.

RMPs
The ACARS MU is supplied with 115 VAC from the 115 VAC
BUS 1 1X.P (sub busbar 103X.P) through the circuit
breaker 2R.B located in the cockpit on the panel 121VU.
The Aircraft Communication Addressing and Reporting
System Management Unit (ACARS MU) manages all tasks
related to the ACARS.
Each RMP receives the same port select discrete signal
as VHF 3 from the ACARS MU.
In normal condition, any RMP is able to tune the VHF
3 transceiver. When a RMP controls the VHF 3 frequency,
it sends a remote voice data select discrete signal
to the ACARS MU to force it to leave the control of
the VHF 3 frequency.
VHF 3
SDAC1
The ACARS MU receives the SDAC 1 main bus and can use
any information present on this bus. The MU can also
trigger ECAM messages.
The ECAM can display messages related to ACARS
operation on the ENGINE/WARNING display.
TMUACAB01-T01 LEVEL 1
UBQ4200
The VHF 3 transceiver is normally used for ACARS data
transmission and reception, but it can also be used
in conventional radio communication mode.
The VHF3 transceiver receives a voice/data discrete
signal which determines the mode of operation : DATA
mode or RADIO mode.
In DATA mode, the transceiver is keyed by the ACARS
MU through the DATA keyline. The digital data exchanged
between the MU and the VHF 3 transceiver are coded by
1200 and 2400 hertz tones.
In RADIO-COMMUNICATION mode, the transceiver can be
tuned either by the ACARS MU or by any RMP. This is
determined by the port select discrete signal sent by
the ACARS MU.

Each report generated by the Data Management Unit (DMU)
can be programmed individually for transmission to the
ACARS MU either automatically or manually.
The ACARS MU can also require generation and
transmission of any report by the DMU. The ACARS MU
can send information to the DMU when each report has
been duly transmitted to the ground.

FWCs
The ACARS MU provides Flight Warning Computers (FWCs)
1 and 2 with data indicating four ACARS configurations.
FWC 1 and 2 enable display of the corresponding
indications on the memo zone of the upper ECAM display
unit. The display unit only shows one indication even
if several configurations are present at the same time.
These indications are :
- ACARS MSG: indicates reception of a ground
message,
- ACARS STBY: indicates loss of communication
with the ground,
- VHF3: VOICE: indicates that the VHF3
transceiver is not controlled by the ACARS,
- ACARS CALL: indicates reception of a voice
communication demand with the ground.

When the FWCs are no longer provided with this data
by the ACARS MU, or do not receive it in normal
conditions, the ACARS MU appears on the faulty system
list (ECAM STATUS page) and the amber ACARS FAULT
warning appears on the upper ECAM display unit.
The ACARS MU receives the FWC1 main bus and can use
any information present on this bus.
PRINTER
The ACARS MU is linked to the printer. Data generated
by the ACARS MU from data transmitted by the ground
and by peripheral computers can therefore be printed,
as well as data entered by the crew through the MCDUs.
The data are transmitted to the printer by the ACARS
MU according to a specific protocol which is also used
by the other computers operating in conjunction with
the printer.

MCS SATCOM SYSTEM PRESENTATION
INTRODUCTION
The Multichannel Aviation Satellite Communications
System (MCS SATCOM) is a worldwide mobile
communications system providing continuous VOICE and
DATA COMMUNICATION SERVICES to and from the Aircraft.
In addition to the Airborne Avionics (referred to as
an Aircraft Earth Station), the total MCS SATCOM system
consists of the Space Segment (satellite network),
Ground Earth Stations (GESs) and Public as well as
Private Voice and Data terrestrial telecommunication
networks.
SPACE SEGMENT
The
space
segment
comprises
satellites
in
geosynchronous
orbits,
providing
air-ground
packet-switched data services and voice communications
using conventions and capabilities which are
standardized worldwide.
TMU23SA01-T01 LEVEL 1
UBQ4200
The satellites function as communication transponders
to support L-band links to and from the Aircraft and
provide links to and from GESs.
There are two space segment providers for Airline
Aeronautical Satellite Communications:
- The first is the INternational MARitime
SATellite organization (INMARSAT), whose
system is in place today to provide worldwide
coverage.
EFFECTIVITY
EFFECTIVITY
ALL
- The
other is American Mobile Satellite
Consortium (AMSC) system and Telesat Mobile
Inc.(TMI), which provides satellite coverage
for North America.
The satellites operated by both AMSC and TMI back each
other up.
The communications systems of either AMSC or TMI
support public, private radio and data networks.
GROUND EARTH STATION (GES)
Each GES has the necessary equipment to communicate
with terrestrial networks and communicate through
satellites with the Aircraft.
The GESs are designed to provide the Airline customer
with a diverse routing of national and international
voice and data communications via submarine cable,
satellite and microwave links to all destinations.
Automatic traffic management systems ensure efficient
routing of communications using optimum links into
Public Switched Telephone Networks (PSTN) and avoiding
multiple satellite connections whenever possible.
The GESs are strategically placed globally to provide
redundancy and diversity in the terrestrial extension
of communications.
The aircraft will be connected to a GES via an "in-view"
satellite depending on the service preference table
settings in the AES Satellite Data Unit.

- flight related data.
The SDU:
- controls timing functions,
- performs voice and data digitalizing,
EFFECTIVITY
EFFECTIVITY
ALL
- performs coding/decoding functions,
- defines system protocols,
- provides other system interfacing.
The SDU is connected to:
- the ADIRS to provide the Beam Steering Unit
(BSU) with relative azimuth and relative
elevation so that the High Gain Antenna (HGA)
can directly be pointed at the satellite for
optimum reception and transmission,
- the CFDIU for BITE,
- the ACARS when the VHF link with ground station
is not possible,
- the Laptop computer for data loading.
The RF signal is sent to the HPA through an attenuator
and received from the Diplexer/Low Noise Amplifier
(D/LNA).
L-band transmission frequency: from 1.6255 GHz to
1.6605 GHz
L-band reception frequency: from 1.530 GHz to 1.559
GHz.
HIGH POWER AMPLIFIER
The HPA is only used for signal transmission and
amplifies the SDU generated L-band signal to a power
level required for proper transmission to the
satellite. The power level is permanently adjusted in
order to minimize the satellite power consumption.
The linear HPA provides the required average output
power, 60 watts per channel, while passing multiple
signals
without
generating
excessive
intermodulations. The HPA also monitors the BSU
activation depending on the satellite position.

L-band reception frequency: from 1.530 GHz to 1.559
GHz.
HIGH POWER AMPLIFIER
The HPA is only used for signal transmission and
amplifies the SDU generated L-band signal to a power
level required for proper transmission to the
satellite. The power level is permanently adjusted in
order to minimize the satellite power consumption.
The linear HPA provides the required average output
power, 60 watts per channel, while passing multiple
signals
without
generating
excessive
intermodulations. The HPA also monitors the BSU
activation depending on the satellite position.

COCKPIT VOICE RECORDER OPERATIONAL MODES
NORMAL MODE
TEST MODE
In normal mode, the cockpit voice recorder records,
on four independent channels, the audio signals from
the captain, first officer and 3rd occupant via the
Audio Management Unit (AMU). Channel 4 records the
ambient noise picked up by the area microphone and fed
via a pre-amplifier to the CVR.
The CVR TEST is initiated by pressing the CVR TEST
pushbutton on the RCDR panel.
A 600 HZ test tone is applied sequentially during 0.8s
to each of the four tracks.
Provided the aircraft is on ground, the signal should
be heard through the headsets. The signal should also
be heard through the loudspeakers if the R and L main
landing gear shock absorbers are compressed and the
parking brake is applied.
ERASE MODE
The Recorder ERASE pushbutton must be pressed in for
a minimum of two seconds to prevent inadvertent
erasure.
The erase head erases the previously recorded
information on all 4 channels simultaneously, before
a new recording is made.
ERASE is only possible, aircraft on the ground, R and
L main landing gear shock absorbers compressed and
parking brake applied.
NOTE: Prior to this test, the CVR must be energized
by pressing the GND CTL pushbutton with the
engines not running.
TMUCOMR03-T01 LEVEL 3

A strap fitted on the AMU enables FAA/CAA recording
selection.
In FAA mode, only communications sent out by the crew
members are recorded. This is obtained by recording
of side tone signal : Audio output.
In CAA mode, the Captain, First Officer, and Third
Occupant microphones are "HOT" (PTT not activated) at
all times for voice/noise pick-up to reinforce the
sounds picked-up by the area mike.
However, in CAA mode, as in FAA mode, the signal
received in the crew’s earphones is recorded on the
CVR.

CABIN INTERCOMMUNICATION DATA SYSTEM DESIGN PHILOSOPHY
GENERAL
PASSENGER FUNCTIONS
Changing market demands require flexibility in
customized cabin layouts and optional cabin systems.
With the Cabin Intercommunication Data System (CIDS),
the operator is able to change the cabin layout without
hardware
changes
(e.g.
cabin
loudspeakers,
PAX-equipment ...).
This can be simply done by entering, on board, new
cabin parameters in the software.
The CIDS is a microprocessor based system. It monitors,
tests, operates and provides control and monitoring
of the cabin functions.
-
PRINCIPLE
CABIN SYSTEMS FUNCTIONS
To manage various functions, the CIDS has a central
unit, the CIDS DIRECTOR. It is linked to the Forward
Attendant Panel (FAP) for control and monitoring of
the cabin functions.
The Director then communicates, through a bus system,
with Decoder Encoder Units (DEUs). The DEUs send (and
receive) information to (and from) the cabin, passenger
and crew systems.
The Director has interfaces to other aircraft systems.
Through a Programming and Test Panel (PTP) the CIDS
can be programmed to customer demand.
The PTP is also used to test the entire CIDS.

NORMAL POWER SUPPLY
ABNORMAL POWER SUPPLY
The directors are continuously energized when the
essential and service busbar are energized.
In normal operation, the essential busbar supplies:
- the active director,
- all the circuitry in DEU A which is necessary
for PA operation,
- all the circuitry in DEU B which is necessary
for PA and interphone.
In normal operation, the service busbar supplies:
- the active and the second directors,
- the remaining non essential circuitry of the
DEUs,
- the programming and test panel,
- the forward attendant panel.
The service busbar also supplies, the area call panels,
the attendant indication panels and the aft attendant
panel, via DEU B.
If service bus power is unavailable, the following
items of equipment are inoperative:
- the second director,
- the non essential D.E.U. circuits,
- the P.T.P. and the F.A.P..
The AIPs and the ACPs are also inoperative because
they are supplied with service bus power by the type
B DEUs.
If a P.A. operation is done, the top line cut-off relay
106RH is no longer energized, and then the essential
busbar supplies the circuitry in type A D.E.U. which
is necessary for P.A. operation.
When the essential bus power is unavailable, circuitry
in the directors and D.E.U.s switches the essential
circuits to the service busbar. This ensures full
C.I.D.S. capabilities exept for emergency mode
operation.
If the aircraft loses main power (the service bus and
the essential bus), and the emergency exit lights
switch is set to ARM or ON, all C.I.D.S. units, which
are supplied by essential bus, are switched
automatically to the hot battery bus.

BITE
TMUCI2E03-T02 LEVEL 1
UBQ4200
On C.I.D.S. energization or reset, all director
interfaces are disabled and the directors are
initialized (self-test). The self-test is repeated
periodically. It also includes a test of the data bus
lines.
The power connections are arranged such that director
1 is normally fully active and in control of the CIDS.
Director 2 is normally partially active, in a
hot-standby mode.
A failure in the initialization process in director 1
causes a deactivation of the director 1 hardware and
a switchover of control to director 2. If the self-test
of director 1 fails, director 2 takes over.
At the same time, the power transfer relay is
de-energized. This prepares director 2 to be
supplied from the essential bus in abnormal or
emergency mode.
The second contact of the relay prepares the control
from director 2 to the top line cut-off relay for the
emergency mode.
The directors internal normal power sensing circuits
are always checking if power is available on the
service bus. If the power fails, the following occurs:
- As long as director 1 is OK, the power transfer
relay remains energized. Via the closed
contact, director 1 sends a signal to energize
the top line cut-off relay.
With the top line cut-off relay energized the emergency
mode is activated. In emergency mode, the power from
the essential busbar is disconnected from all type A
D.E.Us as long as no P.A. announcements are made.
EFFECTIVITY
EFFECTIVITY
ALL
Type B DEUs are directly supplied from the essential
bus but only for PA and interphone operations.
Activation of the P.A. system sets the director 1
internal NAND-gate to 0, which de-energizes the
top-line cut-off relay.
Power from the essential busbar supplies the two
essential circuits of type A DEUs.
All bite results are stored in the director bite
dedicated memory.
Failure indications may be given by the following:
- the CIDS caution light,
- the ECAM warning page,
- the ECAM status page,
- the PTP display,
- the respective MCDU pages.
The following items of equipment have their own BITE
functions and send their BITE status to the director:
- each DEU,
- the Programming and Test Panel,
- the Forward Attendant Panel,
- the connected equipment such as PES.
The DEUs are able to test the connected equipment.

CIDS - TYPE A DEU DESCRIPTION/OPERATION
GENERAL
The type A Decoder-Encoder Unit (DEUs) are located in
the left-hand and right-hand sides above the cabin
windows in the ceiling. Each type A DEU is connected
to a CIDS top line data bus. Each data bus uses a two
wire twisted and shielded cable.
Each type A DEU interfaces with :
- three Passenger Service Units (PSUs)
- two loudspeakers
- four fluorescent strip lights which are part
of the cabin light system.
TOP LINE DATA BUS
FAIL SAFE OPERATION
Two top line data buses on each side of the passenger
cabin connect the type A DEUs to the directors.
A bus termination resistor is located on the last DEU A
mount of each line for impedance matching.
A broken top line can affect no more than half of the
DEUs installed on one cabin side.
In the event of a data bus failure the DEU maintains
the current status of the discrete cabin systems output
for a certain time.
After this delay the outputs are switched to a
pre-defined fail safe state, that means the four
fluorescent strip lights come on at full brightness
and all other items go off.
All audio input/outputs are immediately switched off.
CODING SWITCHES
TMUCI2F02-T01 LEVEL 3
CIDS POWER UP
When the CIDS is powered-up or reset the director
follows a power up routine. This includes the
initialization and testing of each DEU and connected
equipment.
The test results are transmitted to the Director which
compares them with its programmed data to decide on
their status.
At least 95% of possible DEU failures are automatically
detected.

the same. Due to index pins it is not possible to
install a type A DEU on a type B DEU mount.
The mounts for the type A DEUs have the index pins on
the outer side of the slot and the type B DEUs on the
inner side of the slot.
On each DEU mount there are Address Coding Switches.
In case of a mount change the old code must be selected.
A Bus termination resistor is installed on the last
DEU mount of each line, for impedance matching.

NOTE: A table giving the address code is placed close
to the mount.

SOURCES
The CIDS directors accept audio signals from the
various PA sources in the aircraft. The active director
assigns priorities to each source.
It transmits the signal in digital form via the four
top-line data buses to the type A DEUs and, OPTIONALLY
via the Passenger Entertainment System Controller
(PESC), to each Passenger Control Unit (PCU).
The type A DEUs send the signal to the cabin
loudspeakers for broadcasting.
The announcements can be heard, at each passenger seat,
with a headset.
A PA announcement can be manually initiated from the
cockpit and from the cabin.
The announcement from the cockpit can be initiated
with :
- the cockpit handset,
- other equipment: handmike, boomset mike,
oxygen-mask mike in conjunction with the Audio
Control Panels (ACPs),
- the N/S and FSB switches set to ON,
The announcement from the cabin can be initiated with:
- the attendant handsets,
- the Forward Attendant Panel (FAP): from which
the prerecorded announcements, stored in the
PRAM, can be selected and initiated, as the
Boarding Music (BGM),
- If a Video System is installed, PA
announcements can be initiated from the Video
Control Unit (OPTIONAL).
A PA announcement can be automatically initiated from
the PRAM when:
- the N/S or FSB cockpit switches are set to AUTO
and according to the airline definition,
- a cabin decompression occurs.

PRIORITY
The following are the basic levels of priority:
- 1st priority: FLIGHT COMPARTMENT,
- 2nd priority: CABIN ATTENDANT STATIONS,
- 3rd priority: PRERECORDED ANNOUNCEMENT (if
installed),
- 4th
priority:
BOARDING
MUSIC
and/or
ENTERTAINMENT SYSTEM (if installed).
As an OPTION the FWD ATTND STATION could have the 2nd
level of priority, in this case the other ATTND
STATIONS will have the 3rd level of priority.
The levels of priority and the defined options are
programmed in the CABIN Assignment Module (CAM).
TMUCI2N03-T01 LEVEL 3
UBQ4200
PA LEVEL
The volume of PA announcements can be automatically
adjusted if several conditions are met.
It is the active Director which establishes the level
according to the software, sending the level setting
to each individual type A DEU. Then the type A DEUs
perform the required amplification.
When an engine is running, the PA volume is increased
automatically by +6dB.
The PA volume is also increased by +4dB in the event
of cabin depressurization.

PASSENGER ADDRESS SYSTEM OPERATION
PASSENGER ANNOUNCEMENT FROM CABIN
The cabin can be split into a maximum of three cabin
zones, depending on the airline options. This
information is stored in the CAM. The Director uses
it to identify the commands received from the cabin
attendant handsets and to transmit the passenger
announcements to the relevant cabin zone.
An attendant handset is mounted at each attendant
station. An AIP is installed near each handset for
display of PA-use information. When the handset is
lifted, a dialling tone (440 Hz) is heard. The top
line of the AIP displays a sharp # symbol.
Once a PA call is established, the respective PA IN
USE message is displayed on the bottom line of all
AIPs. Cockpit PA IN USE indicator, located on the CALLS
PANEL is provided as an option. The PTT switch keys
the PA system. Sidetone audio is fed to the handset
earpiece.
When the PA announcement is over, you can disconnect
the handset from the PA system as follows:
- put the handset into the cradle or,
- press the RESET button.
TMUCI2O03-T03 LEVEL 3
UBQ4200
When you press the "PA ALL" key, a confirmation message
is displayed on the AIP.
If the PA call is impossible due to the priority of a
call already in progress, then the word BUSY appears
on the AIP display.
To press the keypad RESET key always clears any handset
operation and lets you make a new key selection.
The numbers of all selectable PA zones and the
respective keypad keys, are stored in the CAM. The CAM
also contains a priority list which establishes if an
announcement can be broadcast.

CABIN INTERPHONE SYSTEM D/O
GENERAL
PRIORITY
The cabin and cockpit interphone system enables
telephone communications between the attendant
stations and, between the attendant stations and the
cockpit.
A communication is always initiated by a dial procedure
with the ATTENDANT HANDSET or by pushbuttons on the
CALLS panel in the cockpit.
All communication modes are handled with respect to
the predefined priorities listed below :
- 1, Emergency call.
- 2, Call from cockpit including an all call from
cockpit, and a normal call from cockpit.
- 3, All call from cabin station.
- 4, Normal call from cabin station.
Additionally, all interphone sources have interrelated
priorities, as assigned in the CAM.
If more than one interphone source requests the same
communication mode, the source with the higher priority
will have preference.
If they have the same priority, the interphone source
which was dialled first will be given preference.
SYSTEM DESCRIPTION
TMUCI2Q03-T01 LEVEL 3
UBQ4200
The CIDS director accepts audio signals from the
various interphone sources in the aircraft and assigns
priorities to each source. The director performs
telephone exchange switching and call functions from
cockpit call switch settings or the attendant handset
keypad entries.
All this is done with reference to the parameters
defined in the Cabin Assignment Module (CAM). Chimes
are transmitted via the top line data bus and the
Passenger Address loudspeakers. In the cockpit,
integral lamps in the call switches annunciate
interphone calls. In the cabin, the Audio Control
Panels (ACP) and Attendant Indication Panels (AIP) are
used for annunciation.

PRERECORDED ANNOUNCEMENT & BGM D/O
GENERAL
The function of the Prerecorded Announcement and
Boarding Music (PRAM) Reproducer is to play prerecorded
messages. It also plays boarding music programs on a
cassette tape to the passengers through the aircraft
passenger address system. The PRAM is controlled by
the audio module, which is a part of the FWD ATTND
Panel. It is installed in the cabin at the forward
attendant station. The PRAM and the audio module are
connected with two ARINC 429 data buses through the
Cabin Intercommunication Data System (CIDS) active
director to receive and transmit control data.
The Prerecorded Announcement and Boarding Music (PRAM)
Reproducer is installed in the aft avionics
compartment.
TMUCI2102-T01 LEVEL 3
UBQ4200
PRERECORDED ANNOUNCEMENTS
The Prerecorded Announcement Reproducer (PRAM) has two
cassette decks.
Up to 256 prerecorded announcements are stored on two
tapes in the prerecorded announcement reproducer (each
minimum 30 s). The PRAM has the capability to produce
an emergency announcement in the event of a rapid cabin
decompression. An emergency announcement is stored in
a Solid State Stored Voice (SSSV). A ground signal
from a rapid decompression, triggers, through relay
19WR, the emergency announcement.
All functions are remotely controlled from the audio
module in the FWD ATTND Panel (except the output level
of normal and emergency announcements). They are
adjustable at the front of the reproducer.
EFFECTIVITY
EFFECTIVITY
ALL
The prerecorded announcements can be controlled from
the audio module in the FAP.
BOARDING MUSIC (BGM)
There are two sources for the BGM: the PRAM and the
Passenger Entertainment Audio Reproducer.
The choice of the BGM channels is established by each
customer.
In the PRAM there are two cassette decks for the BGM.
These two cassettes provide four music channels. The
cassette tapes are used alternately. When one is
playing the other one rewinds in order to give
continuous play.
Both reproducers are controlled from the audio module
fitted in the FAP.
The PRAM is automatically initialized at aircraft power
up when the reproducer receives 115 VAC.
The PES audio reproducer is powered when the PES ON/OFF
pushbutton is selected on the audio module in the FAP,
through relay 800MK.

FAP INTERFACES
The FAP is connected to the directors through two ARINC
429 low speed data buses.
Through these buses, the FAP transmits data for
controlling and monitoring of the cabin systems and
receives data from the active director for signalling.
The FAP also transmits, through these lines, its BITE
information :
- A discrete signal is transmitted to the EPSUs
for activation of the emergency lighting,
- discrete signals connect the FAP and type B
DEU for EVAC activation, reset and indication,
- an analog signal connects the FAP and the Water
QTY TMTR for potable water quantity indication,
- discrete signals connect the FAP with the
Potable Preselection Unit for the water
preselection from the FAP,
- an analog signal connects the FAP with the
Vacuum System Controller for waste quantity
indication,
- discrete signal, out of the FAP, for lavatory
lighting, pax reading lights and cabin

PTP CABIN RECONFIGURATION
The programming function is used to change the ZONING
or to perform the CABIN PROGRAMMING.
For the ZONING mode, no access code is required. But
for the CABIN PROGRAMMING mode, an access code is
required.
The ZONING function enables the selection of the number
of ZONES inside the cabin as well as the various NO
SMOKING areas and the CLASS DIVIDER. The CLASS DIVIDER
is a device which separates the cabin zones. Each cabin
zone begins with a NO SMOKING ZONE.
To increase the FWD ZONE by 3 seatrows on the right
section select 06 for the end of the FWD ZONE.
The FWD ZONE ends now at seatrow 06R/04L and the MID
ZONE starts at seatrow 07R/05L.
If a change was made, the flashing message "PARAMETER
SAVING" appears.
With the message "PARAMETER SAVED" the saving of the
new configuration to layout M (Modifiable) and into
the director is completed.
The MODIFICATION counter is incremented and displayed
(Here M = 019).
TMUCI2Y03-T02 LEVEL 3
UBQ4200
CABIN ZONES
For CABIN ZONES programming, the end seatrow number
of each zone has to be entered. The specific functions
will then be automatically adapted.
The NO SMOKING ZONES begin in accordance with the
respective CABIN ZONES. The NO SMOKING signs in these
zones come on steady.
Here are three asymmetrical cabin zones. The FWD ZONE
ends at seatrow 03R/04L, the MID ZONE ends at seatrow
14R/16L and the AFT ZONE starts at seatrow 15R/17L.
In case of symmetrical cabin zones the numbers will
appear only in the right hand positions of the menu
without left hand or right hand separations.
NOTE : Symmetrical or asymmetrical cabin zones are
customer options.

CAM LAYOUT SELECTION
The CABIN PROGRAMMING function is protected by an
access code.
Note that each code digit is marked by a * sign.
The CAM LAYOUT SELECTION function enables selection
of a new CAM layout. When activating the CIDS, the
last selected layout is loaded from the CAM into the
DIRECTOR memory.
The programmed layouts are marked with a "<" or ">"
sign. The number of the last selected layout flashes.
A new layout can be selected by pressing the
corresponding labelled key.
Then this number flashes and the layout is downloaded
into the director.
The CIDS system will then be completely updated.
The CAM shown here includes three fixed layouts 1 and
2 (a maximum of 3 fixed layouts can be programmed) and
the modifiable layout M.
If layout 1 or 2 are loaded and modified, they are
saved into layout M.
Layout M is now loaded.
If no CAM is available, the last downloaded LAYOUT is
maintained in the Director.
If no CAM is available and the last downloaded layout
is defective, the CIDS works with its own layout.
In these cases, the failure message "CIDS FAIL" appears
on the SYSTEM STATUS page.

STEPS TO MODIFY A SELECTED CABIN LAYOUT
- Load the desired layout 1 - 2 - 3 - M into
director (Example "2").
TMUCI2Y03-T05 LEVEL 3
UBQ4200
Select "ZONING" on the PTP.
- By programming steps, the layout data (cabin
zones, no-smoker zones, class divider) is
modified in the memory of the director (in the
RAM).
- After completing the programming, press "RET"
on the PTP, PTP displays "PARAMETER SAVING".
- Note: If "RET" is NOT pressed, the system will
operate with the modified data, until a
power interruption causes a restart of
the system. In this case the modified
data will be lost and the old layout "2"
will again control the function of the
CIDS.
- This stores the modified data in the CAM, layout
"M" and in the memory of the director (in the
EEPROM).
- Reselection of layouts 1 - 2 - 3 is
possible, but "M" holds the modified "2"
version, until a new programming is made.

PASSENGER ENTERTAINMENT SYSTEM PRESENTATION
GENERAL
The passenger address and entertainment
comprises the following basic functions:
system
- Passenger Entertainment System (PES),
- Passenger Entertainment System Video
(PES
video),
- Pre-Recorded Announcements and boarding Music
system (PRAM).
The PES comprises the PES music, the passenger address
and the passenger service.
PES
The PES transmits pre-recorded music programs,
passenger address information, video and video sounds
to the passengers.
The audio signals can be heard through headphones
connected to the Passenger Control Units (PCU).
TMU23EA01-T01 LEVEL 3
UBQ4200
The PCU allows several music channels and video audio
channels to be selected and the volume to be adjusted.
The PCU also allows the reading lights and passenger
calls to be remotely controlled through the Passenger
Service System (PSS).
All pre-recorded announcements (video and sound) and
the passenger address messages, heard in the headphones
through the PCU, have priority over the music and video
sound entertainment channels.
EFFECTIVITY
EFFECTIVITY
ALL
The anouncements and passenger address messages are
also broadcast through the passenger address
loudspeakers, via the CIDS.
The PES audio reproducers supply music channels to the
Main Multiplexer and boarding music channels to the
CIDS director.
The CIDS broadcasts the boarding music through the
passenger address loudspeakers.
Boarding Music (BGM) channel and volume control is
performed on the Forward Attendant Panel (FAP).
The Main Multiplexer is connected to the CFDIU to
ensure the passenger entertainment BITE function.
PES VIDEO
The PES video shows pre-recorded video movies and video
announcements through different display units in the
passenger compartment.
The video sound is transmitted to the Main Multiplexer
and to the CIDS.
Therefore video sounds can be heard from the headset
through the PCU or from the cabin passenger address
loudspeakers.
The in-seat video display units are supplied through
the Main Multiplexer.

signal which contains the audio information from the
audio reproducer (A/R), and Video System Control Unit
(VSCU), passenger address announcements from the Cabin
Intercommunication Data System (CIDS) and video
signals from the VSCU.
Each WDB supplies a maximum of 2 SEB columns.
If passenger address announcements are to be made, the
CIDS sends a keyline signal to the audio reproducer
to stop it.
A coaxial cable transmits the radio frequency signal
to the Seat Electronic Boxes (SEB), according to the
zone selection through the Wall Disconnect Boxes (WDB).
The SEBs only transmit the selected audio signal to
the headsets through the Passenger Control Unit (PCU).
A zone selection, for Passenger Address (PA) and video
sounds, for a maximum of 2 zones, is made through
keylines.
SEB
The Seat Electronic Box (SEB) changes the combined
radio frequency audio signal back to its original
analog form and only transmits the selected program
to the PCU.
Each SEB supplies a maximum of 3 PCUs.
The SEBs receive PCU selected data and transmit it to
the CIDS director, through the PSS and through the MM.
PCU
The Passenger Control Unit (PCU) allows the passengers
to select, to adjust the volume and to hear music and
video sounds.
Each PCU has a stereophonic transducer to drive a
stereo pneumatical headset, or a jack for an electrical
headset, or both.

VSCU
The Video System Control Unit (VSCU) controls the
Passenger video Entertainment System (PES video).
The VSCU receives video and audio signals from the
Video Tape Reproducers (VTR).
It generates a radio frequency signal which contains
the video signals and sends it through the tapping
units to the related display units.
The VSCU operates in the following formats:
- PAL,
- SECAM,
- NTSC.
The VSCU sends the video sounds to the Main Multiplexer
(MM) and to the Cabin Intercommunication Data System
(CIDS) director.
The passengers can hear the video sounds through
headsets connected to the Passenger Control Units
(PCUs) or from the Passenger Address (PA) loudspeakers.
The interface between the optional Cabin and Passenger
Management System (CPMS) and the VSCU allows the
following functions:
- remote control of the video system, camera
control unit and Passenger
- Visual Information System (PVIS),
- display of news and advertisements provided by
the CPMS,
- preview of video programs.
The Passenger Video Information System (PVIS) is an
option that receives information which is processed,
formated and transmitted as video signals to the VSCU.
The VSCU transmits this information to the display
units.
As an option, the video camera converts optical images
into video signals compatible with the video system.
This signal is sent to the VSCU and can be displayed
on the video display units.
The camera can be remotely controlled from the CPMS.
TMU23EE01-T01 LEVEL 3
UBQ4200
Each PA announcement overrides the PES video sounds
in the related zones and stops the video tape
reproducers.
In case of a rapid cabin decompression, the VSCU stops
the video transmission and controls the retraction of
the overhead monitors installed in the overhead stowage
compartment.

DIU
ADIRS
The PVIS comprises the Digital Interface Unit (DIU)
and the Remote Control Unit (RCU). The Digital
Interface Unit (DIU) is the PVIS main unit.
The Digital Interface Unit (DIU) is a computer. It is
connected to the aircraft avionics systems and to the
Passenger Entertainment System Video (PES Video).
The Air Data Inertial Reference System (ADIRS) is
connected to the DIU through two unidirectional ARINC
429 data buses.
- one ARINC 429 low speed data bus transmits the
actual air data,
- one ARINC 429 high speed data bus transmits
the inertial reference data.
The DIU interfaces with:
- The Air Data Inertial Reference System (ADIRS),
- The Flight Management and Guidance Computer
(FMGC),
- The Passenger Entertainment System Video (PES
Video),
- The Centralized Fault Display Interface Unit
(CFDIU).
TMU23EI01-T02 LEVEL 3
UBQ4200
The DIU processes all the information and selects the
appropriate maps and points of interest stored in its
memory.
The DIU is also connected to other systems:
- the Aircraft Communications Addressing
Reporting System (ACARS),
- the Cabin Management System (CMS).
The DIU is supplied with 28 VDC.
and
The RCU is the input device for the PVIS.
The RCU front plate has four pushbutton switches and
an LCD character control screen.

ALL
FMGC
The Flight Management and Guidance Computer (FMGC) is
connected to the DIU through a unidirectional ARINC
429 data bus.
The FMGC sends data to the DIU. Certain parameters
requiring an input (destination, flight time,...) can
be entered either by the cabin staff or loaded from
FMGC.
CFDIU
The Centralized Fault Display Interface Unit (CFDIU)
is connected to the DIU through a unidirectional ARINC
429 low speed data bus.
ACARS
The Aircraft Communications Addressing and Reporting
System (ACARS) is connected to the DIU through an ARINC
429 low speed data bus.
The ACARS allows connecting gate, arrival information,
messages and other data to be uplinked from ground
stations.

OPERATION
The DIU reads data from the FMGC and the ADIRS through
ARINC 429 data buses. This information is processed,
formatted and transmitted as a video signal to the PES
Video.
The Video System Control Unit (VSCU) transmits this
information to the display units to be displayed.
