AVIONICS DOMAIN Overview The AVIONICS DOMAIN is composed of: -2 redundant servers named Aircraft Network Server Unit-OPerationS (ANSU-OPS). These servers supply computing and memory resources to the hosted OIS applications, documentation and database. -2 redundant routers named Aircraft Router Unit-OPerationS (ARU-OPS). These routers manage data exchanged between the AVIONICS WORLD, the Network Server System (NSS) and its Human Machine Interfaces (HMIs). -1 Secure Interface Router Unit (SIRU) is dedicated to decontaminating Aircraft Communication Addressing and Reporting System (ACARS) messages coming from ground and to safely connect Portable Multipurpose Access Terminals (PMATs) and Flight Attendant Panels (FAPs) giving access to some NSS AVIONICS DOMAIN hosted applications, -2 Secure Communication Interfaces (SCIs), which supply safe and duplex communication between the OIS applications and the AVIONICS WORLD. Both SCIs also do the same between the OIS applications and the Airline Operational Control (AOC) centers through the ACARS network. The Centralized Data Acquisition Module (CDAM) supplies aircraft parameters and avionics data from the AVIONICS WORLD to the NSS for recording and for OIS applications needs. -1 Open World Diode (OWD), which allows a unidirectional data flow coming from the AVIONICS DOMAIN and going to other NSS domains and some cabin systems. Note that the OWD is an electrical device that gives a single way of communication from its left to its right. It prevents malicious data coming from its right going to the avionics domain and to the avionics world.


The AVIONICS DOMAIN is accessible from the cockpit, from the cabin and from additional areas on the A/C, through various interfaces, which are: -The CAPT and the F/O Onboard Information Terminals (OITs) with their keyboard and Additional Control Device (ACD) mainly dedicated to the flight crew, -The Onboard Maintenance Terminal (OMT), including a media drive (Compact Disk (CD) reader/writer and Digital Video Disk (DVD) reader), dedicated to the maintenance staff, -The PMATs dedicated to maintenance staff (PMAT is a ground support equipment), -The main and upper deck Flight Attendant Panels (FAPs) dedicated to the cabin crew, -And the Printer-1, installed on the pedestal, dedicated to flight crew and maintenance staff.

AVIONICS DOMAIN Architecture The AVIONICS DOMAIN supplies services like onboard/AOC centers communication capability, maintenance tools, recording, e-documentation and servicing tools. These services are done by the NSS and OIS applications and documentation. These OIS applications and documentation include: -Communication between the A/C and the AOC centers managed by an AOC application, -Maintenance operations with an Onboard Maintenance System (OMS) application and a Virtual Digital Aircraft condition monitoring system Recorder (VDAR) application, -Recording of A/C parameters with a Virtual Quick Access Recorder (VQAR) application, -Electronic documentation with a Cabin Crew Operating Manual (CCOM), a Configuration Deviation List (CDL) and a Minimum Equipment List (MEL), -Servicing with a Refuel application. These applications are hosted in two redundant servers called ANSU-OPS. Both servers are connected to each other for their database synchronization and to get through loss of one ARU-OPS. These applications dialogue with the AVIONICS WORLD through two redundant routers (ARU-OPS) and two redundant SCIs. Moreover they receive data coming from the AVIONICS WORLD through the CDAM. The onboard/AOC centers communications are done through the Avionics Communication Router (ACR) application installed in the Core Processing Input/Output Module (CPIOM)-D3 and various communication means such as High Frequency Data Radio (HFDR), VHF Data Radio (VDR) and SATellite COMmunication (SATCOM).


Two switches called "OIT SIDE" switches are used to display on each OIT data, from applications hosted either in the AVIONICS or FLIGHT OPERATIONS DOMAINs. Two Units called OIT-Terminal Processor Unit (TPU) are dedicated to process the data coming from OIT keyboard and Additional Control Device (ACD) and the data coming from the FLIGHT OPERATIONS DOMAIN. The OITs display the OIS applications hosted either in both ANSUs-OPS or CAPT and F/O laptops. The PMAT, located in the upper avionics bay, gives access to OIS maintenance applications through 9 dedicated network plugs installed in the A/C (forward Lower Deck Cargo Compartment (LDCC), main avionics bay, upper avionics bay, refuel panel, nose landing gear, aft lower LDCC, aft avionics bay, OMT rack and APU compartment). A "GND CONNECTION" P/B allows: -In ON position (P/B pressed in), the PMAT to be connected to the SIRU, -In released out position, the PMAT to be disconnected from the SIRU. The main and upper FAPs give access to the CCOM and the cabin logbook. Two NSS Control Units (NCUs) are dedicated to control the power up and power down of certain NSS LRUs. A FAN is mounted on the ARU-OPS, 2 and the ANSU-OPS, 2 to provide backup ventilation in case of loss of the main avionics bay ventilation. The main protocol of communication used in the open world is the Ethernet.

SCI-CDAM The AVIONICS WORLD and the OPEN WORLD need to exchange data to each other. Depending on their type, data are sent either through CDAM or SCIs. The CDAM fulfills an unidirectional gateway function for A/C parameters coming from LRUs and LRMs and going to specific OIS applications. This gateway function converts AFDX and ARINC 429 data into Ethernet. The SCI fulfills a bidirectional gateway and security functions for various data, exchanged between various LRUs and OIS applications. These LRUs are: -PDMCs for the control of the Electronic C/Bs. This is in Ethernet format, -LRUs for OMS data, Ground/Flight data, etc. These data are converted by both SCIs from discrete or ARINC 429 format into Ethernet format and vice versa. -LRUs and LRMs, through the ADCN, for OMS data. These data are converted by both SCIs from AFDX format into Ethernet format and vice versa. There are two SCIs for redundancy purpose. Only a single SCI at a time, the one declared "active", exchanges data between AVIONICS WORLD and OPEN WORLD. The SCI toggles between passive and active status in two conditions: after 6 hours of operation and in flight phase number 12. Both SCIs exchange their health data in Ethernet format and their active/inactive status in discrete format to each other. A "NSS DATA TO AVNCS" P/B allows: -In pressed in position, data to flow in both directions between the OPEN WORLD and AVIONICS WORLD, -In OFF position (P/B released out) data to flow from the AVIONICS WORLD to the OPEN WORLD only.

NCU The "NSS AVNCS" C/B are used to fully reset: through the NCU 1: -The ANSU-OPS 1, -The ARU-OPS 1, -The CAPT OIT, -The OMT, through the NCU 2: - The ANSU-OPS 2, -The ARU-OPS 2, -The F/O OIT, -The SIRU. The "NSS FLT OPS" C/B are used to fully reset through the NCU 2: -The ANSU-AFMR, -The ARU-AFMR. The power down lasts 120 seconds and the power up 140 seconds approximately. To carry out maintenance operations, the NSS servers can request, through the NCUs, the power up and power down of the NSS LRUs (called: "REMOTE ON/OFF REQUESTS"). In case of NCU unavailability, the ANSUs can do the same operations through the routers (called: "BACKUP ON/OFF REQUESTS"). Each NSS LRU sends, through the NCU, their 115 VAC status (presence or not of power supply) to the dedicated ANSU for maintenance need.

NSS Power Supply Reconfigurations The AC BUS supplies most of NSS LRUs and the AC ESS BUS supplies a few NSS LRUs. In case of loss of these buses: -Up to 5 seconds, the power supply board of some NSS LRU is switched to the DC BUS, DC ESS BUS or HOT BUS power supply, -After than 5 seconds, a power supply shutdown of the NSS LRUs is started (the shut down lasts up to 120 s). The NSS LRUs supplied by the AC BUS and able to switch to the DC BUS are: -Both ARUs-OPS, -The SIRU, -The CAPT OIT, -The CAPT OIT-TPU, -The OMT. The NSS LRUs supplied by the AC ESS BUS and able to switch to the DC ESS BUS are: -The F/O OIT, -The F/O OIT-TPU, -The ARU-AFMR. In addition, the ANSUs-OPS and ANSU-AFMR are able to switch to the HOT BUS for up to 120 s in order to avoid a hard shut down and therefore loose data. The CNSU-PAX includes a battery to avoid a hard shut down in case of power supply loss. On ground and on battery, the AC EMER BUS supplies the: -The F/O OIT, -The F/O OIT-TPU, -The ARU-AFMR. This configuration helps the F/O to prepare the next flight with his laptop. MAINTENANCE COURSE - T1 & T2 (RR / Metric) LEVEL III - ATA 46 Network Server System & Onboard Information System

On ground, on battery and the "REMOTE C/B CTL" P/B pressed in, the AC EMER BUS supplies: -The SCI 1, -The ARU-OPS 2, -The ANSU-OPS 2, -The NCU 2, -The OMT. This configuration gives the mechanics access to the Power Distribution Control System (PDCS) on the OMT in order to control the remote C/Bs. The "NSS MASTER SW", when released out, activates a hard shut down of NSS LRUs installed in this upper avionics bay 2900VU (in case of smoke detection).

COMMUNICATION & CABIN DOMAIN Architecture The COMMUNICATION and CABIN DOMAIN supplies services such as PAX services, communication management capability and maintenance tools. These services are done by the NSS and OIS applications. These OIS applications are hosted by the server named CNSU-PAX. The CNSU-PAX hosts various applications, which are: -E-mail and Internet applications, -Communication management application, -Wireless Local area network Manager (WLM) application, -Local Maintenance Function (LMF) application. The E-mail and Internet applications are used for the related passengers to write and receive e-mail, and to surf the net during flight. The communication management application manages the data links using the SATCOM system (e.g.: communication channel opening and closing, channels selection based on cost). These data links, using the SATCOM system through an optional High Speed Data Unit (HSDU), are used by the E-mail, Internet and Electronic Flight Folder (EFF) applications and certain cabin systems such as CVMS and IFE system. The WLM application transmits configuration data to the CWLUs (e.g.: wireless communications not available during TAKE OFF). The LMF supports maintenance operations dedicated to COMMUNICATION and CABIN DOMAIN components. A passenger with a PED (e.g. laptop) can access to e-mail and Internet applications through a Seat Electronic Box (SEB), an In-Flight Entertainment Center (IFEC) and the CRU-COM. The type of connection between this PED and the SEB may be USB or RJ45. A passenger with a wireless PED (e.g. laptop equipped with a WIFI board) can access to e-mail and Internet applications through 4 leaky line antennae and 4 CWLUs.

Each leaky line is connected to both CWLUs through coaxial links. The four leaky lines cover the total length of the main and upper deck cabin. An airline cabin laptop may be connected to dedicated plugs, one located at the door M1R, and one at the front face of the CNSU-PAX, for maintenance purpose (e.g. to access to the LMF application). The type of connection between this airline cabin laptop and these plugs is RJ45 at the door M1R, and RJ45 or USB at the front face of the CNSU-PAX. A "NSS CABIN" C/B is used to reset the CNSU-PAX, the CRU-COM and the CWLUs. The "PAX SYS" P/B, when released out, activates a hard shut down of all CWLUs (in case of smoke detection). The COMMUNICATION and CABIN DOMAIN routes data coming from the AVIONICS DOMAIN for the CVMS (e.g.: flight number) and the (IFE) system (e.g.: airshow data).
