11. Winlink 2000 System What is WL2K? Introduced in 2000 (DCC 2000) WL2K is a modern software implementation of a Global ham message system capable of conventional BBS functions with significant extensions for the Mobile user.Introduced in 2000 (DCC 2000) WL2K is a modern software implementation of a Global ham message system capable of conventional BBS functions with significant extensions for the Mobile user. mobileBiased toward the mobile user. –Conventional BBS functions with routing and store and forward for radio and E-mail messages. –No “Home BBS” designation required (global message mirroring) –Optimized to capitalize on Internet forwarding when possible –On demand WX products and other Web information. –E-mail with text/compressed binary attachments –Position reporting and request from radio and Internet Currently 4300 Users (HF Pactor, Packet, Telnet, Web) delivering over 150,000 messages per month by 36 PMBOs.

13. Motivation for Telpac and Paclink WL2K has been very well accepted by the mobile HF community Many requests to expand local WL2K coverage (VHF/UHF) Emergency communications Small portable terminals Two obstacles for widespread VHF/UHF expansion: The standard PBMO setup requires a considerable computer, radio equipment and synchronized data base. Telpac provides a simple Telnet to Packet bridge The user client program has to work with most available TNCs and interface with existing E-mail clients. Paclink provides a user client that meets these objectives DCC 2003

14. Development Approach Leverage existing standardized interfaces & protocols: Existing WL2K Telnet Servers via Internet/Telnet Standard TCP communication between components Standard mail format and server protocols: MIME message storage POP3 and SMTP servers Capture TNC drivers using a standardized TCP interface AGW Packet Engine Use modern development environment and tools for improved productivity and reduced support Telpac: VB6, Paclink: VB.NET DCC 2003

15. Telpac…WL2K’s Telnet <> Packet Bridge Key Features: Easy set up No local database Multiple active connections Supports all WL2K functions AGW Packet Engine support DCC 2003

22. The AGW Packet Engine with Telpac and Paclink AGW Packet Engine TNC Sound Card TNC TCPIP … By George Rossopoulos, SV2AGW Standardized TCP interface supports most TNCs Using KISS mode. Supports sound card TNCs (1200 & 9600 baud) Shares TNCs across applications Paclink, Telpac, BBS, APRS, Terminal, Monitor Allows remote operation via TCP link TNC’s may be separated from application DCC 2003

23. Telpac and Paclink Applications Telpac as a conventional BBS for “Last Mile” wireless connectivity Paclink as an end user client for BBS access (WL2K, FBB etc) Paclink as the an emergency radio link for Internet E-mail Paclink provides the radio connection to a WL2K Telpac node Emergency field operators use their existing E-mail client but with a “radio” account instead of default account Multiple operators can share a single Paclink and its TNCs/radios Paclink <> Paclink transfers (keyboard or via E-mail clients) DCC 2003
