(cont.)
Leased Interface Network Communications Service
(LINCS)
Air-to-Ground links, ATS Ground-toGround Communications, and
Backbone circuits
Federal Telecommunications Service
(FTS)
Dial-up services for administrative
and routing communications.
Users include: FAA Headquarters,
Regional Offices, Aeronautical

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)
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

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

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.
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.

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
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
