ConvTek is a certified services provider for Virtel, which is published by Syspertec Communication and is distributed by VirtelUS, Inc.  Using Virtel, ConvTek can:

• Extend 3270 applications to the Web without any code modification
  
• Adapt their presentation, ergonomics, navigation, and workflow to the Web
  
• Reuse time-proven legacy code to develop new GUI-ed Web applications

Simple Two-Tier Architecture

The Web-enabling solution benefits from its simple two-tier architecture:

• 100% mainframe-based
  
• Light client: nothing to install or support on clients
  
• Simply point the client's Web browser to a pre-defined URL
  
• No intermediate components or layers (no middleware, no applets, no API, no Web browser code additions, no Telnet, no JAVA, no GTG, no CWS, etc) and none of the associated bottlenecks, breakdowns, complexity, and dispersed support
  
• On-the-fly Web-to-3270 protocol converter runs on mainframe next to 3270 applications
  
• Easier to deploy and support than middleware, client-based, rewrite, or re-hosting solutions

Mainframe Strength and Performance

The Web-enabling solution takes full advantage of the strength and performance of the mainframe it resides on:

• As fast, robust, secure, scalable, and dependable as the mainframe it runs on
  
• Clever design reduces network traffic, code execution, and resource consumption
  
• Coded in Assembler and executing compiled HTML templates for top performance
  
• Production-proven with up to 15,000 simultaneous users
  
• Combines mainframe and IP security through VIRTEL's own filters and URL controls
  
• Faster, stronger, and more secured than middleware, client-based, rewrite, or re-hosting solutions

Cost Effective Reuse of Legacy Investment

The Web-enabling solution allows cost effective reuse of legacy investment:

• Quickly and easily opens 3270 applications to the Web without any code modification
  
• Easily developed HTML templates:
  
  • Adapt 3270 presentation, ergonomics, navigation and workflow to the Web
    
  • Transform 3270 applications into full-featured Web applications
    
• No screen scrapping for easier maintenance
  
• Allows creating new Web applications from time-proven and reliable legacy code
  
• Development, control, and support remain centralized and mainframe-based
  
• Costs less and leads to faster deployment than middleware, client-based, rewrite, or re-hosting solutions
