•
• This presentation highlights the efforts of the CAR/SAM
ATN Task Force, which has been enforce for the past
three years. The Task Force Fourth meeting will be
held at the end of June 2008 in Santo Domingo,
Dominican Republic.
• The scope of the CAR/SAM ATN Task Force is to
– Ensure smooth transition from Aeronautical Fixed
Telecommunication Network (AFTN) to AMHS environment
and
– Prevent any possible interruption in the AFTN and Air Traffic
Voice service operation during the transition period.

Our Vision:
Service
and Plan
Safety
• In 2006, the CAR/SAM region adopted AMHS over
TCP/IP to replace their AFTN service.
• Various States in this region have obtained or are in the
process of obtaining, the AMHS and AMHS/AFTN
Gateway.
• The first AMHS service over IP will be implemented
between Argentina and Paraguay, and it is projected
for the middle of 2008.

Issues
Our Vision: Transitional
Service and
Safety
• AMHS Network Protocols
• CLNP/TP4
• IPS-based networks
• MTA to MTA Communication
• Dual Operation of AMHS and Alternative Routing
• A well coordinated upgrade of the circuit data rate table
will be needed to support alternative routing
• AFTN circuits Upgrades

Transitional Issues
Routing Policy should be developed to
address the following:
•
Intra-Region MTA routing during the AFTN/AMHS transition
period.
•
Intra-Region MTA routing at End-State Environment.
•
Inter-Region MTA Routing during transition period.
•
Inter-Region MTA Routing at End-State Environment.

Binary Universal Form Representation (BUFR) code
– BUFR code was developed by the ICAO OPLINK Panel.
– BUFR code is used to provide graphic meteorological data.
– BUFR code was targeted for distribution by AMHS because
AFTN can not support binary based messages.
– BUFR code has been adopted by the WMO and the ICAO but
XML is also being considered.
– The ICAO Regional Offices have been analyzing the BUFR
code to determine the impact to AMHS (AMHS X.500 based
Directory Service versus modifying the MTA).

IP Transitional Issues
•
The aeronautical communication industry (i.e., AMHS system providers) have
not fully developed the MTA to support IPv6.
•
The Technical Manual for the IPS will be finalized by the Aeronautical
Communication Panel (ACP) in late 2008. However, ICAO Doc. 9880 Part II B
for AMHS is now available.
•
Initial implementations in the ICAO European Region are using AMHS over
IPv4 in separate sub-regions. Two of these sub-regions are interconnected via
IPv6 using a network address and protocol translation technique whereby IPv4
messages are converted to IPv6 across the interface and then back to IPv4.
•
Many CAR/SAM member States have already implemented the AMHS or will
replace the AFTN service in the near future.
•
The Asia/Pacific region needs to [work out] resolve the network protocol issues
with European and South American regions (ATN router or IP router).
•
A global AMHS network coordination is required to ensure smooth operation.
•
Implementing security measures.
•
IP addressing scheme needs to be developed for AMHS

AMHS Transition Plan would include the following
appendices to address variety of issues:
 Appendix I

OPERATION CONSIDERATIONS
MTA to any MTA (via IP)
• This is the end state goal. In the interim, the regional major hub
should take active role to ensure the smooth operation.
Dual operation of AFTN and AMHS
• Dual Operation during transition period will require regional major
hubs to act quickly to prevent significant network problems.
Regional AMHS Management Center
• A Regional AMHS Management Center should be designated to
timely coordinate with other regions and within region to support
the AMHS cutover activities as well as AMHS operation.
System performance standards
• Develop System Performance Standards to address legal
recording, tracking message, delivering of messages, etc.
