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
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.
PASSENGER FUNCTIONS
- general cabin illumination control,
- passenger address,
- passenger call,
- passenger lighted signs,
- passenger reading light switching.
CREW FUNCTIONS
- cabin and flight crew interphone,
- service interphone,
- emergency evacuation signalling.
CABIN SYSTEMS FUNCTIONS
- boarding music,
- pre-recorded announcement,
- lavatory smoke warning,
- temperature regulated drain mast system,
- emergency lighting.
MONITORING AND TEST FUNCTIONS
- system programming and test,
- work light test,
- escape slide bottle pressure monitoring,
- reading lights test,
- extended emergency lighting test.

CABIN INTERCOMMUNICATION DATA SYSTEM PRESENTATION
GENERAL
The CIDS consists of the following components:
- the Directors including ON Board Replaceable
Memories (OBRM),
- the Programming and Test Panel (PTP) including
Cabin Assignment Module (CAM),
- the Forward Attendant Panel (FAP),
- the Additional Attendant Panels,
- the Type A Decoder Encoder Units (DEUs A),
- the Type B Decoder Encoder Units (DEUs B),
- Cockpit equipment,
- Cabin equipment.
DIRECTORS
For redundancy, two directors are installed.
In normal operation of the CIDS, director 2 is in hot
stand-by.
Both directors receive the same inputs and perform the
same computations. The outputs of the director in hot
stand-by are disabled.
The directors are connected through two CIDS busses
to the type A and type B DEUs to carry the various
data to the cabin equipment.
The FAP, PTP and other systems are connected directly
to the directors basically for control, indication and
test of the CIDS functions.
TYPE A DECODER ENCODER UNITS
The type A DEUs provide the interface between the
directors and the passenger related systems.
TYPE B DECODER ENCODER UNITS
The type B DEUs provide the interface between the
directors and the attendant and cabin related systems.
FORWARD ATTENDANT PANEL
The Forward Attendant Panel (FAP) is installed at the
