The VIRTEL Company (VIRTEL), a division of the Syspertec Group, is a French independent software publisher founded in 1993 that develops, markets, and supports a comprehensive suite of System Z access and modernization technologies. VIRTEL has over 30 years experience helping organizations modernize access to and integration with z/OS and z/VSE applications to save money, simplify support, and improve mainframe security.

Virtel Web Suite is a suite of mainframebased technologies that serve host applications as HTML5/JavaScript web pages and/ or standard web services over secure TCP/ IP connections. It is comprised of three (3) product configurations utilizing the same underlying protocol conversion technology.

Virtel Web Access (VWA) is a pluginfree, browser-based 3270 terminal emulation solution that securely serves 3270 screens as HTML5/JavaScript web pages to any web-enabled device. VWA replaces outdated TN3270 terminal emulators and VTAM session managers to save hard dollar licensing/support costs, simplify support, and improve mainframe access security.

Virtel Web Modernization (VWM) creates modern Graphical User Interfaces (GUIs) for 3270 applications. Using it’s next-gen IDE called Virtel Screen Redesigner (VSR), it securely serves 3270 host transactions as customized, user-friendly web pages to create a genuine web 2.0 UI experience that improves the usability and extends the life of legacy applications and investments.

Virtel Web Integration (VWI) creates interactive, bi-directional connections that integrate mainframe and server applications using standard web services protocols and formats to provide a highly scalable, resilient and cost-effective application integration outcome.

The Virtel infrastructure is comprised of Virtel mainframe started tasks (STCs), one or more VTAM/SNA interfaces to 3270 applications, an HTTPS server managing SSLencrypted TCP/IP connections with the Internet, and a conversion engine between VTAM/SNA and TCP/IP technologies. (see Figure 1)

Virtel Web Access (VWA) securely serves 3270 screens as standard HTML5/JavaScript webpages over encrypted HTTPS connections to plugin-free web browsers. VWA provides near identical 3270 terminal emulation (TE) ergonomics as outdated TN3270 products, and is an attractive modernization replacement for TN3270 emulators and VTAM session managers.

• Platform independence because it works with any browser on any web-enabled device

• Simple cross-application navigation using the Virtel Tier Application Menu for VTAM session manager replacement

Virtel Web Modernization (VWM), featuring the next-gen Visual Screen Redesigner (VSR) IDE, transforms host transactions into web pages that produce a genuine web experience (see Figure 2). VWM overcomes issues early generations of 3270 GUI interface tools experienced and is a better, faster, and more cost-effective solutions than redeveloping, replacing, rehosting, or frontending 3270 applications.

• Utilizes an intuitive, powerful IDE that features a drag-and drop interface design, customizable widgets, re-useable HTML templates, and a real-time preview capability • Requires NO change to the mainframe application

Virtel Web Integration (VWI) creates realtime, bidirectional connections to integrate host applications like CICS and IMS with server applications to produce a highly scalable and resilient application integration result. VWI exposes host transactions either through legacy 3270 screen UIs or a COMMAREA for screenless transactions.

• Supports any web services protocol and formal: RESTful, XML, JSON, SOAP, MQ, and more
