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.


Faa ground to ground atn implementation plan

ATN Subnetworks (continued)

  • 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 ...

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 Applications Implementation


Faa ground to ground atn implementation plan

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 ApplicationsAMHS

  • 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.

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, 3rd Edition

  • Service will be operational by 3rd 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


Faa ground to ground atn implementation plan

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


Faa ground to ground atn implementation plan

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


Faa ground to ground atn implementation plan

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
