FAA ATN Backbone Infrastructure

Current FAA Data/Voice Communications Networks National Airspace Data Interchange Network II (NADIN PSN) X. 25 Administrative Data Transmission Network (ADTN) TCP/IP Bandwidth Manager (BWM) Data Multiplexing Network (DMN) Packet Switched Network (PSN) Users include: AFTN, MSN, WMSCR, TDWR, TMS, CNS, …etc. Wide area network service for both dedicated and dial-up. Users include: FAA Headquarters, Regional Offices, Aeronautical Center, Technical Center, OCC, NOCC, AFSS, and…etc. Switched voice and data, video conferencing, bandwidth on demand 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) Air-to-Ground links, ATS Ground-to. Ground Communications, and Backbone circuits 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, and…etc.

Future FAA Data/Voice Communications Network FTI (FAA Telecommunications Infrastructure) FTI TCP/ IP CLNP ATM Frame Relay VOICE X. 25

ATN Subnetworks • • A 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) l Almost any data communications network can be an ATN subnetwork: - X. 25 Frame Relay IP LAN Aeronautical Mobile Satellite VHF Digital Link Leased Lines, etc. . .

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

FAA ATN Program Plan Current FAA ATN Plan: • Implement BIS routers network to support the domestic and global ATN networks • Implement AMHS servers to support Ground-to-Ground the Aeronautical Message Handling Service • Implement 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

Current FAA ATN Program Plan • FAA Ground to Ground ATN BIS routers implementation plan: - ZOA (Oakland) ZMA (Miami) ZNY (New York) ZLC (Salt Lake) ZTL (Atlanta)

FAA ATN Applications Implementation

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

ATN G/G Applications AMHS • • 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 also performs as a gateway for AFTN/CIDIN, as required.

CPDLC Controller Pilot Data Link (CPDLC) provides two ways communication between pilot and controller, but using data link rather than voice: • Exchange of Controller/Pilot messages. • Transfer of data authority. • Delivery of downstream* clearance. *Downstream is ahead of the aircraft, toward the destination.

US ATN/AMHS Implementation Plan and Schedule FAA is currently implementing ATN/AMHS • Requirements are in full compliance with ICAO SARP, 3 rd Edition • Service will be operational by 3 rd quarter of Calendar year 2003 to comply with FAA/JCAB Bilateral Agreement • Existing AFTN service with JCAB will be maintained in parallel during transition period

Summary • The FAA is in the process of replacing its telecommunications infrastructure which includes: ` AFTN service ` X. 25 base network ` Modem network ` Voice/Data network ` LAN/WAN/Email system ` Backbone 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 sites ` AMHS The new ATN network will replace the obsolete MSN and its service while providing better network management and security FAA also implements the CPDLC Air to Ground ATN application

Summary (continued) • The ATN backbone will allow FAA to respond • to the telecommunications technology evolution without interfering with the neighboring states network infrastructure Implementing ATN will allow seamless transmission of ATN messages with minimum impact/delay to transiting domain

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