Study Notes
Telephone and Fax System
- The fax machine provides normal telephone functions with additional features like a credit card reader and LCD display.
- The telephone system is connected to the Satellite Communication System (SATCOM) via the Passenger Entertainment System Controller (PESC) and the Cabin Telecommunication Unit (CTU).
- The System Control/Interface Module has master control of communication between the fax, credit card reader module, and bearer system.
Passenger Visual Information System (PVIS)
- The PVIS supplies passengers with in-flight visual information through the Passenger Entertainment System (PES) video display units.
- PVIS provides real-time flight and destination data, including aircraft position data on maps and aircraft status data as text.
- Modes of Airshow operation are set from the Cabin Management Terminal (CMT).
Decoder/Encoder Units (DEU)
- DEU-A interfaces with the active DIR to control passenger-related systems, such as Passenger Service Units (PSU), PAX lighted signs, PAX-call lights, and loudspeakers.
- DEU-A interfaces with the Cabin Intercommunication Data System (CIDS) via a data bus.
- DEU-A is connected to the DIRs through a CIDS data bus, with two top-line data buses on each side of the left, centre, and right seat aisles for redundancy.
- DEU-As are interchangeable and have installation addresses given through coding switches installed in each DEU-A connection box.
Cabin Intercommunication Data System (CIDS)
- CIDS is a microprocessor-based system that controls and displays cabin functions for passengers and crew.
- CIDS components include CIDS Director (DIR), Decoder/Encoder Unit A (DEU A), Decoder/Encoder Unit B (DEU B), Forward Attendant Panel (FAP), Additional Attendant Panel (AAP), and Area Call Panel (ACP).
CIDS Director (DIR)
- DIR is the central control and interface component of CIDS.
- There are two identical DIRs, one active and one in hot-standby mode, for redundancy.
- Each DIR receives the same inputs and processes the information, with results checked via a crosstalk bus.
Communication Functions
- CIDS Communication Links include passenger address and integrated pre-recoded announcement/boarding music, cabin interphone, and service interphone.
- Passenger Address (PA) system supplies one-way voice communication for announcements from the cockpit or cabin crew station to passengers.
Cabin Programming and Warnings
- CIDS cabin layout selection function allows reconfiguration without complex hardware changes.
- Cabin programming modes are available on ground or in flight, protected by an access code.
- CIDS warnings are provided through Built-In Test Equipment (BITE) circuitry in DIRs, DEUs, FAP, AAPs, and AIPs, allowing detection of faults in connected systems.
