Questions


What is Winlink 2000 (aka WL2K)?

It is a volunteer designed and operated communications system that provides reliable E-mail service over MARS and amateur radio Frequencies regardless of the user’s physical location.

In english: It lets you send and receive email to/from the internet via radio: HF Pactor, VHF Packet, or via Telnet on your computer.


The Acronyms:

  • PMBO Participating Mail Box Office

  • RMS Radio Messaging System

  • CMS Common Message Servers

  • Telpac Telnet Packet

  • AirMail An WL2K Client (program) a user runs on his computer to access (send and receive) e-mail on his computer

  • PaclinkMP A new WL2K Client (replacement for AirMail)


Advantages over ‘classic’ BBS / Node / and other Radio Messing Systems

  • Seamless message communications between Internet and all supported radio modes

    • A single domain for E-mail (@winlink.org)

    • No H-routing, No ‘home’ BBS, etc

  • Compatibility with existing packet networks

  • Multiple-destination Addressing of Messages (Amateur, MARS, and internet E-mail)


Advantages over ‘classic’ BBS / Node / and other Radio Messing Systems

  • Transparent File Attachments

  • Reduce HF Radio Airtime

    • Use a fast user client program

    • Inter-MBO forwarding on Internet

    • User Time Limits and Lockouts

    • Minimize/eliminate “keyboard” connections

  • Worldwide Access Via HF for Mobile Users

  • Local Access Via UHF/VHF for Fixed Users and for Packet Interconnection


Existing Ham/MARS Messing Systems

Radio Networks

Telnet, VHF/UHF Packet, HF Pactor

Winlink Today

WL2K ‘LAND’

Three mirrored CMS sites in

Washington, San Diego, and Perth

Internet

PMBO/RMS

Telnet, D-Star,

VHF/UHF Packet

WiFi, Etc.

Paclink at Served Agency

VHF/UHF Packet

Telpac

Served Agency LAN

Individual Users

(AirMail, Paclink)

User’s standard Email Client

Outlook, Thunderbird, etc.

Radio Domain


Winlink 2000 Today By The Numbers Messing Systems

  • Demonstrated > 99.9% system availability since implementing mirrored servers

  • 3 Full-time Redundant Common Message Servers (CMS) in Washington, San Diego and Perth, all in hardened “caged” sites, with power backup, provide excellent reliability

  • 102 total PMBO/RMS sites, worldwide, in 4 service classes: Public, ARES, Army/Air Force MARS, and UK Cadet Forces

  • Approximately 10,000 Radio users, 100,000 Email recipients, currently running an average of 150,000 messages monthly and growing.

  • Average monthly HF connection time of 280,000 minutes with an average duration of 3.3 Minutes and 3,600 bytes/per message.

  • Typical message latency sender to recipient delivery 4 to 5 minutes, less locally

  • In the ARES Service Class, there over 400 Active VHF/UHF Telpac Gateways with many more on standby for emergency operation


Mars wl2k current status
MARS WL2K: Current Status Messing Systems

  • The formal Agreement between Army MARS & the WDT now complete.

  • DHS HQ Common Message Server/PMBO now in place (CMS Washington).

  • Secure FTP site to be moved to Fort Huachuca.

  • Proposed Fort Huachuca CMS/PMBO in process.

  • The Network is fully operational. It is very robust.

  • MARS WL2K is being reviewed, proposed, and used, by an ever-increasing number of Agencies.

    (This is dated – someone in This audience can update us)


What is a CMS (Central Message Server) ? Messing Systems

  • Routes all messages between PMBO/RMS sites and messages to and from the Internet

  • Sends all outbound Internet mail messages to their addressees (no relays)

  • Receives and routes all messages addressed to <callsign>@Winlink.org

  • Automatically registers all users and tracks their locations and PMBO/RMS usage

  • Provides additional services . . .

IT IS A SYSTEM LEVEL DATA BASE THAT HOLD ALL E-MAIL UNTIL THE INTENDED USER RECIEVES IT. FOR REDUNDANCY, THERE ARESEVERAL OF THEM (3) DISPERSED GEOGRAPHICALLY AND PERIODICALLY SYNCHRONIZE SO THEY ALL HOLD THE SAME MESSAGES/INFO.


What is a PMBO or RMS? Messing Systems(Participating Mail Box Operator) (Radio Message Server)

  • Routes messages between users sharing the same PMBO or RMS site

  • Receives messages for local users from CMS sites

  • Forwards all radio messages to a CMS site for further handling (internet or radio destinations)

  • Forwards all message and connection status data to a CMS site for further handling

  • Maintains a local user directory


What is TELPAC (TELnet PACket) ? Messing Systems

  • Connects one or more VHF packet users and channels directly to a PMBO/RMS site using telnet

  • Works over hardwired, D-Star, WiFi, or any channel capable of supporting TCP/IP

  • Reports QTH to APRS and Status to CMS

  • Simple transparent, no-maintenance installation and operation


TELPAC for Win 98 – Win XP Messing Systems

Simple Setup:

Computer,

Packet TNC,

FM VHF Radio,

Antenna,

Internet connection


What is AirMail? Messing Systems

  • AS A USER: This is the program YOU load on YOUR computer and send/receive e-mail via WL2K – (HF Pactor, VHF/UHF Packet, Internet, etc)

  • Acts as a personal E-mail client for a radio user

  • Supports Pactor, packet, and telnet connections to a PMBO or RMS site – directly or via a Telpac gateway

  • Optionally provides propagation forecasting for picking optimum HF radio channels

  • Provides a catalog of PMBO/RMS locations and frequencies

  • Provides extensive bulletin catalog


Using AirMail… Messing Systems

You tell AirMail your TNC, and Radio Configuration.

Then compose and send your message just as with any Email Client

What is Paclink MP? Messing Systems

  • Provides an SMTP/POP3 port into Winlink for served agencies so they can use Winlink services with their existing LAN and Internet email client.

  • Works over VHF/UHF packet, HF Pactor, D-Star, WiFi, or telnet.

  • Supports automatic multiple prioritized channels for message delivery

  • Minimizes training of served agency personnel

PACLINK is the next-generation AirMail – it integrates WL2K intoyour Outlook/Outlook Express / Thunderbird / Etc., email client

When you have Airmail ‘down’ you might want to try Paclink MPas a replacement or adjunct to Airmail – (it is still under development)


Using Paclink MP… Messing Systems

You pre Configure Prioritized Pactor, Packet Or Telnet “Channels”

Each “Channel” becomes a way to connect to WL2K

Once configured Paclink needs no user interaction…simply send email

From your existing Mail Client (Outlook, Thunderbird, etc.) and

Paclink MP automatically routes it through the best “channel” to WL2K and your destination!


Emergency Use Messing Systems

WL2K’s mission is to provide our users and agencies with the value-added services they want. Today, that includes digital messaging in the form of de facto e-mail extendibility. The network is in place, proven and fully operational. It is now up to us to be organized and trained with the proper tools to respond to any casualty event.
