Virtel Web Access

Upgrade from 3270 emulation to pure web access


Virtel Web Access extends host applications such as CICS, IMS, Natural and TSO to thin-client web browsers over secure HTTP/S connections, without changing the user experience:

  • 3270 screens are converted to web pages that look and behave like classic green screens
  • Navigation remains PFK-based: virtual PFKs are served to mobile devices
  • Data is entered in the form expected by 3270 applications
  • Nothing to install or support outside the mainframe

This makes Virtel Web Access a natural upgrade from – and an attractive alternative to – 3270 terminal emulation.

Virtel benefits

Virtel’s thin-client two-tier architecture simplifies the deployment and support compared to client or middle-tier server based products. There is nothing to install or support outside the mainframe: no client apps and no additional servers. Installation and support are 100% host-based, users simply point their web browsers to an installation-defined URL to reach the logon menu.

  • Lower installation and support costs, resulting in a low TCO
  • No middle-tier servers to purchase, configure, monitor, balance, or support
  • No additional licensing fees to comply with new technology implementations or OS upgrades
  • Opportunity to eliminate costly VPN and session manager solutions

Classic 3270 terminal emulation solutions typically rely on HLLAPI or Java technology. Instead, Virtel relies on standard web technology (HTTP/S, HTML, JavaScript): it will work instantly with any web browser running on any web-enabled device, available today or tomorrow.

Virtel supports BYOD and mobile access initiatives: thanks to its compliance with standard Web technology (HTTP/S, HTML, JavaScript), the 3270 emulated web pages it serves can be rendered using any OS (all versions of Windows, Linux/AIX clients…) and any mobile device (tablets, smartphones), including Apple products.

Virtel complies with UTF-16 specifications, allowing global deployments in countries using DBCS workstations like Japan, China, or Russia.

Virtel combines industry-standard mainframe and IP security with a proprietary token-based security system: customers no longer need a VPN connection to secure their mainframe access.

Also, Virtel’s application selection menu (together with the multi-windows capability of web browsers) provides simple multi-session functionality; some Virtel customers have already got ridden of their session manager tool.

These Virtel functionalities allow significant savings in licensing and support costs.

The same Virtel core technology used to serve 3270 terminal emulating web pages can also be used to:

* These functionalities require Virtel Web Modernization and/or Virtel Web Integration license upgrades.
