       Digital Messaging for ARES®
          Presented by the ARRL “ARESCOM” Committee

  “Our primary mission is to provide Global digital
communications for the benefit, safety and well-being
of the user community, anywhere, anytime, anyplace.”

                               By
                     Steve Waterman, K4CJX
               Winlink 2000 Network Administrator,
                Winlink 2000 Development Team
                    (Member of ARESCOM)
                       revised July 28, 2004
          Why are we here?
July, 2003: In cooperation with its partnership
with Homeland Security & at their recommendation,
the ARRL Board sought to provide a Nationwide
digital system to enhance the communications
capability of the Amateur Radio Emergency Service
(ARES) There are situations, the Board said, when
ARES "must have the capability to pass digital
traffic across the Nation quickly and accurately.”
         In harmony with the ARRL BOD’s wishes,the following
        recommendation resulted from the ARRL Resources
        Volunteer Committee (VRC final Report to the ARRL
        BOD, July 2003:)
   A new network should:
    •    provide rapid transfer of emergency traffic between Sections,
    •    Provide flexible access between Sections,
    •    be automated as much as practical,
    •    use available and future digital modes,
    •    interface with commercial communications systems such as
         conventional telephone, cellular telephone, and the Internet, etc.,
    •    have speed, performance and accuracy,
    •    deliver the emergency traffic end-to-end,
    •    provide immediate traffic delivery (crucial,)
   September, 2003: “ARESCOM” committee formed by Jim
    Haynie, ARRL President.
       ARESCOM’s Mission: To recommend a National Digital
        network for ARES® to the ARRL BOD for its July, 2004
        meeting:
       ARESCOM’s Recommendation to the ARRL Programs
        and Services Committee: The inclusion of Winlink 2000
        for the ARRL ARES.
   July 15, 2004: the ARRL approved the inclusion of
    Winlink 2000 into ARRL ARES.
         (Excerpts from the ARRL WEB Site, July 20, 2004)

   The ARRL Board adopted a resolution encouraging further development and
    expansion of an inaugural network to enhance the emergency communications
    capability of the Amateur Radio Emergency Service® (ARES) The Board's motion
    encouraged the deployment of e-mail via Amateur Radio--as exemplified by Winlink
    2000--"as an additional emergency capability provided to agencies served by ARES.

   In its report, the committee said situations arise when ARES must "pass message
    traffic across the nation quickly and accurately," and it said the need for such a
    nationwide capability within ARES is likely to increase in light of the ARRL's Citizen
    Corps partnership with the Department of Homeland Security

   Members of the ARRL Programs and Services Committee witnessed a Winlink 2000
    demonstration at ARRL Headquarters the day before the board meeting. ARESCOM
    said it wants to adapt the already-proven communications network to meet the needs
    of served agencies and other organizations involved in providing disaster
    communications.

   "The digital network will provide a value-added service for ARES and will continue to
    be viewed very positively by our served agencies," the committee said in its report.
    "This allows ARES to be viewed as modern and necessary instead of antiquated and
    invasive."
            Winlink 2000 deployment for the ARRL
             Amateur Radio Emergency Service
   Winlink 2000 has proven to be an outstanding addition to
    the capabilities of ARRL Field Services:
       Provides nearly real-time radio email service for all served agencies
        and the public;
       works in harmony with the resources of the existing manually
        operated ARES, NTS and NTS/D services;
       covers all areas of the Country and beyond;
       allows ARES to provide transparent, seamless, end-to-end digital
        email from the desktops of the served agencies within the Sections.
       greatly enhances the operation of all these combined resources;
         • Increased accuracy, Increased Speed, allows permanent Record, no
           learning curve for end-user, no invasive software in agencies;
       Provides ease of use, works even when infrastructure is damaged;
       Provides served agencies with what they need.
                   Today’s Discussion
   What does the end-user need (& want) to be effective when
    normal digital communications are unavailable? That is
    really what its all about! Let’s examine:
   Traditional role of ARES
   Winlink 2000 System.
       History of Development
       Telpac VHF/UHF-to-Telnet Gateway with Paclink client for local
        area “Last Mile” coverage.
       Airmail Client for Longer Range HF Internet substitution.
       Specialized non-public local/Regional Winlink 2000 participating
        station (PMBO ) to hub community digital traffic.
   Implementing Winlink 2000 for Emergency Management
         TRADITIONAL ROLE OF HAM RADIO SUPPORT

Hand the microphone to the Serving Agencies whose radio systems will not
work.

Voice communications among served agencies (EOC, hospitals, shelters, and
incident command.)

Report health and welfare of affected public.

Tactical support – Incident Command, search and rescue, damage and storm
reporting (SKYWARN.)



                This takes a lot of people!
             WHAT TYPES OF INFORMATION ARE EXCHANGED?

  "Where the #@! is the tank truck that was headed this way an hour ago?"
  “What Specific food is needed for people who are registered in the shelter?"
  “Parents and 3 children safe, but children require specific medical attention .
  Details to follow."
  "St. Luke's hospital has taken in fourteen victims. Details to follow".
  "Have you finished searching sector seven? What can I report?”
  "This city block is about 20 percent damaged. Details to follow"
  “Standby for detailed Medical procedure information.”
  “Standby for detailed instructions for fixing the generator.”

TRADITIONAL MODES USED: CW & voice on HF. Voice, Packet BBS on VHF/UHF.

TRADITIONAL NETWORKS EMPLOYED: Local/’State/section/regional traffic nets
over wide areas. Specialized networks such as SKYWARN.

                   Can Traditional methods do the Job?
                     A quote from the former FCC Director
                      of Engineering and Technology

"In the past, hams have adopted more spectrally efficient technologies - for
example, by migrating from double-sideband amplitude modulation to single-
sideband modulation and, more recently, by shifting to more efficient
modulation for digital modes. I would urge you to continue shifting towards
more spectrally efficient communications techniques - especially digital
techniques. Such a shift has a number of benefits:

·First of all, it demonstrates to policymakers and regulators that you are good
stewards of the public's airwaves even without direct economic incentives.

.Second, by using what you have efficiently, it strengthens your case when
you need to ask for additional spectrum.

·Third, by allowing more users to access the available allocations
simultaneously, it improves the amateur experience and ultimately increases
the attractiveness of the service to new and old users alike.
                 A quote from the former FCC Director of
                 Engineering and Technology (continued:)
·Fourth, it provides the opportunity or "headroom" for increases in data
rates to more closely match those available on wire line networks and, in
the future, on commercial wireless networks as well.


·Fifth, as the rest of the telecommunications world makes the transition to
digital techniques - and there are very few exceptions to that trend - the
amateur service will look antiquated if it is not making progress in that
direction as well.

So looking to the future of the amateur radio service in the new century, I
would urge you to continue your traditional role in public service by being
prepared for and providing communications in times of emergencies,
conducting experiments, providing training in radio communications, and
encouraging international comity. But I would also urge you to focus
particular attention -- for the reasons I just mentioned -- on experimentation
with digital techniques."

         their own kind of discipline”

“I can’t work without a blackboard!”
         Emergency Digital (written) Communications
                 For Community Agencies
With Telex?   When was the last time they used Telex?
With a Telegram?   When was the last time they sent a Telegram?
With a voice relayed NTS Radiogram or MarsGram? (could be an attachment)
With Packet “H-routing”?

The accepted Global standard is now SMTP e-mail !


                 We can keep Agencies connected
                  without an immediate Internet
                           connection.

   Bottom Line: Let’s make EmComm as easy & transparent as
   possible for those who need it during an emergency situation.

   Let’s not forget: It is their “party” and we want to be invited!
Agency Focus on Emergency digital communications


       Normal E-mail requires an internet connection




                    Agency to Agency
                    Agency to Field
                    Agency to multipoint
                    Agency to anywhere!
                 Agency Focus


   If a community “Last Mile” internet link is
    broken, e-mail cannot flow.
                                              “Critical
      “What
                                             Medical &
       the

      ????”
                                               sent!”
                    Agency Focus


The “Last Mile,” an important part of Emergency
Communications:

The incident area where conventional communications have
been totally disrupted or overloaded by an emergency situation.
In today’s World, we cannot predict the size, nature or location of
       our disaster areas! We be must prepared, Globally.
    Local?               Regional?                    Global?
                   End-User Focus



Amateur Radio can provide e-mail to any served agency
without the internet within the “Last Mile,” across the
Nation, or around the World.




                                    HOW DO HAMS DO THAT?
             ? ? ?
             ? ?
                 ?
How can an Amateur Radio Emergency Service provide a
Local, State, Regional, National or Global digital e-mail
capability to its community’s agencies when various
normal Internet links are broken?
    Agency Focus on Emergency digital communications: Requirements
   It must “look like e-mail.”
   It must “use an e-mail editor like MS Outlook Express or Outlook, etc.”
   It must “have an address book like e-mail.”
   It must “include multiple recipients (to:, Cc:) like e-mail.”
   It must “send multiple binary attachments like e-mail.”
   It must “have a spell-checker like e-mail.”
   It must “work on multiple computers within an agency with no
    additional desktop software, and not invade the security of the system.”
   It must “provide transparent, seamless, end-to-end email when
    there is no normal Internet path.”
   It must be able to utilize tactical email addresses.
   It must “NOT add to the stress or learning curve of those who are
    already stressed in an emergency situation.”



                           How do Hams do that?
Welcome to the Power of Winlink 2000 !




Where in the World are you? It doesn’t matter!

    haul HF” to link community Packet BBSs.
        Used by the Military during 1st Gulf War for H & W & hidden ID troop
         movement detail. 1991 CBS 30 minute documentary: “Last Voice from
         Kuwait” with Charles Kuralt.
        NTS/MARS usage heavy. Still used by both ! Still the currently adopted
         system for NTS/D & MARS.
   1997: Winlink Classic with NetLink & Airmail client Link HF digital radio
    messages to Internet SMTP e-mail.
        World adopts SMTP (IETF RFC822) e-mail. MARS/NTS did not. NTS/MARS
         dropped off… “The Internet is not ham radio.”

        Current Paclink                                    New Paclink

1.   Paclink consist of one Module.               1.   Paclink consists of 2 separate modules, the Paclink Post
                                                       Office (email server) and the Paclink AGW
                                                       Communications module.
2.   Paclink has unlimited number of              2.   Same.
     Channels.
3.   Paclink uses call letters as email           3.   Email addresses are separate from from Calls. A 'single
     addresses (One channel = one call = one           site callsign' handles all the tactical email addresses at a
     email account.                                    given site. When a Paclink Post office is set up, the local
                                                       site call sign is set up as a 'default' account, which is
                                                       usually the sysop address. However, no other radio call
                                                       can be used for an account name at that site.
4.   Call SSIDs are significant in defining an    4.   The PMBO pays on attention to the call sign, but looks for
     email address.                                    the actual email address. Therefore, Call SSIDs are not
                                                       relevant and may change in nodes or switches with no
                                                       adverse effects. This will allow the inclusion of most
                                                       formerly unusable complex Packet paths.
5.   The path of communications for Paclink       5.   There are 5 user-definable auto-routed priority paths for
     is manually set to either Telnet or Packet        Paclink communications: (Example: Telnet, 9,600 Baud
     via the AGW Packet Engine.                        Packet direct, 9,600 baud Packet indirect,
                                                       1200 Baud Packet direct, HF Pactor (future).
6.   Paclink-to-Paclink now possible.             6.   Paclink only communicates to the Winlink 2000 network.|
7.   Paclink must be installed manually.          7.   Paclink now has an install Wizard.

         A BASIC WINLINK HF LONG RANGE FIELD STATION

You will need the following equipment:
 •Amateur radio High Frequency (HF) transceiver (IC-706KIIG, great!).
 •Pactor capable modem: (Pactor II @ 800 bps. P3 @ 3600 bps. Highly
 recommended over Pactor 1 @ 200 bps.
 (Example: an 80 Kbyte file on Pactor 1: approx. 80 Min, On Pactor 3, approx 5-7 min.)
 •HF multi-band (mobile/portable) antenna, and possibly an antenna tuner
 (SGC 230 is great)!
 •12V DC power source
 •Laptop Computer (Win 95, 98, ME, NT, 2000, XP) and Airmail for HF.
         Winlink 2000 Future Enhancements
           Currently Under Development
   CMBO & Backup will become 6-8 multiple “CMSs”
   PMBOs will become RMSs
       Less complex RMSs will randomly route to CMSs
       Ability to alternate route from Internet to RF only during
        EmComm.

   Telpac: Add HF forwarding.
   Paclink: Add HF forwarding.
   Additional High-speed protocol.
 So, what does
all this look like?


“Real life” examples
Harris County (Houston,) Texas
Winlink 2000 is a proven, existing,
operational, dependable, redundant,
secure, reliable Amateur radio email
messaging network that is being made
available to the ARES community.
(However, each community of interest must
put it in place.)
                      So, What’s Next?

   ARES: what other options are available for Seamless Radio email? Do
    they provide end-to-end, transparent, SMTP email throughput to the
    community Served Agencies desktops?
   Make a “yes/no” decision about Winlink 2000. If “yes,” then...
        Learn to use Airmail, Telpac and Paclink.
        Deploy local Telpac gateway(s).
        Deploy mobile Paclink stations & fixed Paclink LANs in places
         where it will be used during an emergency.
        VHF/UHF new or existing links to bring it all together.
        Deploy self-powered, mobile/fixed Airmail, long-range HF Stations
        Consider a non-public “hubbing” PMBO for the area
   Meanwhile…..
                       Devise a Plan!
   Insure that there is no duplication of efforts in your “last mile” coverage
    area.
   Set up an strategy for implementation with your local ARRL ARES
    organization. Set up a time-line for each task.
        Coordinate efforts with the Winlink Dev. Team, EC’s,SECs,DECs/SM,
         etc.
        Ask other ARES communities for assistance.
        Set up personnel responsibilities with Time-lines!
        Handle the finances. “How much will it actually cost”?
        Involve and commit the end-user. They are the one’s to benefit!
   Implement the plan in stages.
   Test it, and Test it again.
   Provide a presentation and demo for your served agencies.
   Continue to promote your capabilities.
