Traditional role of ARES What does the end-user need (& want) to be effective when normal digital communications are unavailable? Winlink 2000 System. Overview of Winlink 2000 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 Winklink 2000 for Emergency Management Communications

Hand the microphone to the Serving Agencies whose radio systems will not work. Voice communications among served agencies (EOC, hospitals, shelters, and incident command.) Formal Written Communications (NTS Form  Voice  NTS Form) 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! Traditional Role of Ham Radio Support

We can keep Agencies connected without an immediate Internet connection. Via Telex, Telegram or Fax? Via voice relayed NTS Radiogram or Packet Message? The accepted Global standard is now SMTP ! 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! Emergency Digital (“Written”) Communications for Served Agencies

Why Messaging? Using is universal Minimum training required Large amounts of data/information may be exchanged accurately: Detailed damage or status reports Detailed work assignments and shift changes Lists of equipment and supplies Graphic or text-based Medical information Anything else that may be handled routinely by Every transfer is a permanently stored record Data is secure from casual monitoring

Normal requires an internet connection Agency to Agency Agency to Field Agency to multipoint Agency to anywhere! Agency Focus on Emergency Digital Communication

If a community “Last Mile” internet link is broken, cannot flow. “What the ????” “Critical Medical & Tactical Info sent!” Agency Focus (Cont.)

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. Agency Focus (Cont.)

It must “look like .” It must “use an editor like MS Outlook Express or Outlook, etc.” It must “have an address book like .” It must “include multiple recipients (to:, Cc:) like .” It must “send multiple binary attachments like .” It must “have a spell-checker like .” 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 when there is no normal Internet path.” It must be able to utilize tactical addresses. It must “NOT add to the stress or learning curve of those who are already stressed in an emergency situation.” Agency Requirements

Amateur Radio can provide to any served agency without the internet within the “Last Mile,” across the Nation, or around the World. HOW DO HAMS DO THAT? End-User Focus

Welcome to the World Winlink 2000! Where in the World are you? It doesn’t matter!

… a robust wireless backup system for SMTP . It utilizes a full-featured radio digital message transfer system, worldwide. worldwide. …a system that provides transfer with attachments, map & text-based position reporting, graphic & text-based weather bulletin services, and emergency communications are now available to the Amateur radio community by linking radio to the Internet.” … over Ham Radio! Winlink 2000 is …

Winlink 2000 is a system that provides radio digital backup (during network “last mile” disruptions) for SMTP , using existing programs, on existing computers, with no additional invasive software…seamlessly and transparently. Winlink 2000 can function both inside the local area or around the world. From inside a disaster area and without normal servers or Internet. Why Winlink 2000?

Originally created five years ago for open water boaters and RV users Endorsed by the ARRL as a viable emergency digital communication system Approximately 150,000 radio message/260,000 minutes through system, monthly. Over 7,200 weekly users to over 85,000 recipients. Over 45 Standard Participating locations (PMBOs) with 24 in USA. Many locations contain multiple stations. 2.1 minute Ave. est. delivery time to PMBO for Pickup Over 670 VHF/UHF Telpac gateways in operation. HF radio access, VHF/UHF radio access, Telnet Access, WEB Browser Access. New Inclusion of non-public EmComm PMBOs. Enhanced, more flexible & redundant network topology currently under development with even less Internet dependency. Winlink 2000 Today

Winlink 2000 Public use PMBOs

Features Worldwide, proven, existing, reliable,redundant system with its own on-going management and support systems. Looks and works like common SMTP . Uses any combination of SMTP addresses mixed with Radio addresses. For EmComm, can use tactical addresses. Multiple “to” and “CC” addressing. Sends multiple binary attachments. Handles tactical addresses. Secure due to binary protocol & secure user login. Easy to configure and use. Software is free, hardware is NOT! WEB browser/Telnet or VHF/UHF/HF access Winlink 2000 Feature Overview

System is fault tolerant & completely redundant. Flexible: Can use existing packet nodes, or digis, or switches. Can use existing Participating Stations (PMBOs.) Has backup remotely located Central Servers (CMBO.) Older generation BBSs may be replaced with Telpac nodes. Intelligent “follow me” routing. Distance insensitive, transparent nodes: Local, Regional, National or International…it does not matter. Winlink 2000 Features (Cont.)

Highly adaptable for emergency use. May replace “broken” Internet links: local, regional, national or international. Designed for mobile or fixed operations. The Winlink 2000 Catalog may be tailored for detailed instructions, policy employment, complex procedures or medical information for each community. Position Reporting for locating mobile users: ARRS ShipTrak Text-based reply tracking system Auto non-published real-time Position Tracking. NOAA MAROB weather reporting system May be expanded for SKYWARN applications. Local “Hubbing” PMBO can maintain connectivity among community Agencies with or without the Internet! Winlink 2000 Features (Cont.)

Uses “B2F” binary Protocol: It is in the public domain. Secure against “hacking” due to compression & error correction. May be wrapped by most ARQ modes. Provides approximately 44 percent data compression. Needs no “special” consideration in a secure IT Infrastructure. Works inside, outside the firewall (DMZ) or router. All user Interfaces may be password protected. “Instant” self-registration option can be turned on/off. Heavy virus/SPAM protection: accept list, etc. can all be turned on/off. NO learning curve for end-user agencies. NO additional stress! Winlink 2000 Features (Cont.)

Winlink 2000 complies with § for an Automatically controlled digital station: For Wider than 500 Hz: (b) A station may be automatically controlled while transmitting a RTTY or data emission on the 6 m or shorter wavelength bands, and on the MHz, MHz, MHz, MHz, MHz, MHz, MHz, MHz, or MHz segments. For 500 Hz: (c) A station may be automatically controlled while transmitting a RTTY or data emission on any other frequency authorized for such emission types provided that: (1) The station is responding to interrogation by a station under local or remote control; and (2) No transmission from the automatically controlled station occupies a bandwidth of more than 500 Hz. Winlink 2000 complies with § Station control, for 3 rd Party traffic rules: (e) No station may be automatically controlled while transmitting third party communications, except a station transmitting a RTTY or data emission. All messages that are retransmitted must originate at a station that is being locally or remotely controlled. Winlink 2000 complies with Section §97.219(c) for 3 rd Party traffic Content Rules: §97.219(c) provides protection for licensees operating as part of a message forwarding system. "...the control operators of forwarding stations that retransmit inadvertently communications that violate the rules in this Part are not accountable for the violative communications. They are, however, responsible for discontinuing such communications once they become aware of their presence.“ Winlink 2000 complies with § for data emission codes. (4) An amateur station transmitting a RTTY or data emission using a digital code specified in this paragraph may use any technique whose technical characteristics have been documented publicly, such as CLOVER, G-TOR, or PacTOR, for the purpose of facilitating communications. Winlink 2000 complies with Sub-Part E when so designated (i.e.: § Safety of life and protection of property): No provision of these rules prevents the use by an amateur station of any means of radio communication at its disposal to provide essential communication needs in connection with the immediate safety of human life and immediate protection of property when normal communication systems are not available. Winlink 2000 in U.S. and Part 97

CMBO PMBO TP AM PL CMBO: Central Mail Box Office - The CMBO is the central server (coordinating engine) in the Winlink 2000 "star" Network configuration. It coordinates the traffic between the participating network stations (PMBOs) as well as serving as the , WX bulletin, and position reporting interface. All this is done over the Internet in order to make the amateur radio spectrum more efficient, leaving these radio frequencies available for the end-users. PMBOPMBO: * Participating Mail Box Office - A Winlink 2000 participating network MBO. PMBOs communicate with each other through the CMBO in a "star" network configuration via the Internet and with the end-users and other MBOs over radio. Includes Telnet Server Module.Telnet Server TelpacTelpac: * A Winlink 2000 bridging application that allows the connection of a VHF/UHF modem, either directly or via the AGW Packet Engine, with a Paclink or Airmail user application, and converts the AX.25 Packet to Internet Telnet for connection to a Winlink Participating Station' s (PMBO) Telnet Server. Paclink:Paclink: * A Winlink 2000 client server application that enables the use of a single or multiple computers with program interfaces such as MS Outlook, MS Outlook Express, Netscape, Eudora, etc. for the purpose of sending and receiving via Telnet or VHF/UHF Packet. Paclink utilizes the AGW Packet Engine to drive Packet modems, including computer sound cards. with one single Paclink application, in front of a firewall and behind a router, multiple computers may be enabled with radio when used with the Winlink 2000 network system. Paclink has 5 automatic routing levels. Airmail: AirMail is " for the airwaves", a radio messaging program for ham, Sailmail and other licensed radio systems. AirMail offers an easy -style user interface for HF and VHF Packet. Airmail, also designed for the SCS PTC multimode controller. PE AGW Packet Engine Pro is a special Windows© utility for amateur radio operators who use ‘Packet' digital communications. This unique program makes it possible for multiple Packet programs to access multiple Packet devices, such as TNCs (Terminal Node Controllers) or radio modems, and sound cards acting as radio modems. Generally most Packet programs can only use one device at a time and most Packet devices can only be used by one program at a time. Packet Engine Pro changes all that.
