Web-enabling legacy 3270 applications like CICS and IMS with VIRTEL starts with the Web Access module, and continues with the Web Modernization and Web Integration modules. Moreover a number of other modules fits special needs, such as eliminating 3270 emulation, providing email services, etc.

VIRTEL WEB Access extends legacy 3270 applications to the Web almost instantly, in less than 2 hours!  It allows adapting their presentation to the Web (fonts, colors, PF keys, etc.), eventually transforming them into full-featured Web applications with the addition of unlimited Web-specific ergonomics and features such as clickable fields, command buttons, combo boxes, pop-ups, calls to other Web servers, and the likes.  Clients only need a standard JavaScript-capable Web browser, and no additional software.  VIRTEL requires no CICS exit, no middleware, no Java applets, and it doesn't use screen scraping.  Web-enabling developments require simple HTML and JavaScript (Optionally VIRTEL Script) skills.  VIRTEL's host-based Assembler-coded two-tier solution delivers outstanding scalability, performance, robustness, and reliability, and allows combining existing host security (RACF, ACF2, TSS) with IP security components (proxy, firewall, SSO gateway, SSL security box) through its filtering rules and URL controls.  With Web Access, the legacy code and navigation remain unchanged.  More ..

 

VIRTEL WEB Modernization provides different modernisation and development solutions for user interfaces.
The objective is to modernise and/or develop the interface of legacy applications to provide users with a truly dynamic Web application without the need for redevelopment. More...

 

VIRTEL WEB Integration provides a response to the integration concerns and requirements of companies.
The objective is to make transactions and data on the host accessible and usable by any other server or Web application in order to create composite applications. More...

 

VIRTEL-EK (3270 Emulation Killer) is a restricted-use version of VIRTEL WEB Access competitively-priced to replace 3270-emulation:

  • In this configuration, users permanently maintain their VTAM terminals with timeout set to zero; VTAM terminals are disconnected only if users click a disconnect button or stop their Web browser; i.e. 100 users "consume" 100 VTAM terminals
  • Every "Entry Point" connected to "HTTP Lines" must have its timeout set to zero

 

VIRTEL-X2P (X25 to IP) is used to eliminate 3745/NPSI:

  • Emulates both XOT (X25 over TCP/IP) and NPSI
  • Mainly dedicated to X25 support, it allows encapsulating X25 in IP using the XOT function of CISCO routers
  • NPSI emulation (GATE, Fast-Connect, and PCNE) allows any mainframe applications using these protocols to work transparently through VIRTEL

 

VIRTEL-eMS (eMail Services) is an SMTP server.

 

VIRTEL-OC (Outgoing Calls) includes:

  • Management of connection to any External Server accessible through an X25 address
  • Emulation allowing any user (3270 terminal, emulation, or Web browser through Web Access module) or mainframe (MVS, VSE, VM) application (mainly CICS) to access external applications using VT100 and 200 (VTxxx), 3270 (3174R where VIRTEL manages a pool of LU for a remote virtual 3174), videotext (VDX), TTY, or specific structured format message (TTY)
  • VIRTEL base module: lines, rules, entry-point, transactions, terminals definition, and security interface (RACF, ACF2, TSS) 

 

VIRTEL-IC (Incoming Calls) includes:

  • Management of connection to any VTAM application through an X25 address
  • Emulation allowing any user (Minitel terminal, VIRTEL PC emulator, VTxxx terminals, etc.) of an X25 network to access VTAM applications
  • Functions that support applications built with GTM, GTM/OSI, or CSFI, and allow eliminating those products
  • VIRTEL base module: lines, rules, entry-point, transactions, terminals definition, and security interface (RACF, ACF2, TSS) 

 

VIRTEL-VR (VTAM Relay) includes:

  • Management of the connection to any VTAM application
  • VTAM session manager, compression (3270 data flow optimization), security (user, profile, and resources)
  • VIRTEL base module: lines, rules, entry-point, transactions, terminals definition, and security interface (RACF, ACF2, TSS)
