FAA ATN Backbone Infrastructure

Current FAA Data/Voice Communications NetworksNational Airspace Data Interchange Network II (NADIN PSN) X.25Administrative Data Transmission Network (ADTN) TCP/IPBandwidth Manager (BWM) Data Multiplexing Network (DMN) Wide area network service for both dedicated and dial-up. Users include: FAA Headquarters, Regional Offices, Aeronautical Center, Technical Center, OCC, NOCC, AFSS, andetc.Packet Switched Network (PSN) Users include: AFTN, MSN, WMSCR, TDWR, TMS, CNS, etc.Switched voice and data, video conferencing, bandwidth on demand and dynamic adaptive routing. Users include: ARTCC and ATCSCC Use multiplexing techniques enable number of independent data signals to be consolidated into a single transmission channel. Users include: Radar data, weather data, ASOS, VORTAC, etc.

Current FAA Data/Voice Communications Networks (cont.)Leased Interface Network Communications Service (LINCS) Federal Telecommunications Service(FTS) Dial-up services for administrative and routing communications.Users include: FAA Headquarters, Regional Offices, Aeronautical Center, Technical Center, OCC, NOCC, AFSS, andetc.Air-to-Ground links, ATS Ground-to-Ground Communications, and Backbone circuits

Future FAA Data/Voice Communications Network

FTI(FAA Telecommunications Infrastructure) FTIATM

ATN SubnetworksA subnetwork is part of the communication network, but is not part of the ATN. It is defined as an independent communication network, which is used as the physical means of transferring information between ATN systems.

ATN Subnetworks (continued)Almost any data communications network can be an ATN subnetwork:X.25Frame RelayIPLANAeronautical Mobile SatelliteVHF Digital LinkLeased Lines, etc ...

Future FAA ATN NetworkFAA will use FTI to serve as a telecommunications subnetwork for supporting FAA domestic ATN

FAA ATN Program Plan Current FAA ATN Plan:Implement BIS routers network to support the domestic and global ATN networksImplement AMHS servers to support Ground-to-Ground the Aeronautical Message Handling ServiceImplement CPDLC to support Air to Ground data communications

FAA ATN Program Plan (Continue) Future FAA ATN Plan:Continue evaluate other Ground to Ground and Air to Ground ATN applications

FAA ATN Applications Implementation

FAA Existing AFTNExisting AFTN is a point-to-point X.25 infrastructure, confirmation is requiredAFTN messages are required to be processed by a transit station (ZLC Salt Lake or ZTL Atlanta) before they can be forwarded, including transited messagesNon deliverable AFTN messages is required to store and forward

AMHS will process ATS messages (e.g. Flight Plans, NOTAMs, etc) and transmit to its end users.Each AMHS will only process messages for its end users in its own domain.AMHS will function in bypass mode for transient messages.Several administrative domains may share a single AMHS.AMHS also performs as a gateway for AFTN/CIDIN, as required.ATN G/G Applications AMHS

ATN ARCHITECTURE

US ATN/AMHS Implementation Plan and ScheduleFAA is currently implementing ATN/AMHSRequirements are in full compliance with ICAO SARP, 3rd EditionService will be operational by 3rd quarter of Calendar year 2003 to comply with FAA/JCAB Bilateral AgreementExisting AFTN service with JCAB will be maintained in parallel during transition period

SummaryThe FAA is in the process of replacing its telecommunications infrastructure which includes:AFTN service X.25 base networkModem networkVoice/Data networkLAN/WAN/Email systemBackbone Point-to-Point dedicated circuits

Summary (continued)FAA will use this opportunity to establish a Ground to Ground ATN network and its application by deploying:ATN BIS routers at various sitesAMHSThe new ATN network will replace the obsolete MSN and its service while providing better network management and securityFAA also implements the CPDLC Air to Ground ATN application

The ATN backbone will allow FAA to respond to the telecommunications technology evolution without interfering with the neighboring states network infrastructureImplementing ATN will allow seamless transmission of ATN messages with minimum impact/delay to transiting domain

Summary (continued)

Summary (continued)ATN environment will satisfy future A/G message delivery requirementFull ATN benefit will be realized if all states implement to ATNIf an organization unable to implement ATN, arrangements need to be made with neighboring organization/state to carry their message through the ATN environment
