Cleo TN3270 / 5250

A Windows, Unix, or Linux Solution for Establishing 3270 connections to IBM mainframes or AS400.

Cleo’s TN3270 / 5250 is designed for high-performance mainframe communications where reliability and efficiency are critical. Some typical mission critical applications are Interactive Voice Response (IVR) systems, large credit card processing servers, large-scale retail chains, CTI, dealer or franchisee communication.

Cleo’s TN3270 / 5250 product features:

  • Support for up to 4,000 sessions
  • High reliability
  • Low CPU utilization
  • Complete management of all sessions
  • Session pooling
  • HLLAPI programming interface
  • Printer support
  • Automatic error recovery

Connecting to single or multiple mainframes through one or more TN3270 servers, Cleo TN3270 / 5250 supports every function of the TN3270 E specification. TN3270 / 5250 also provides a LU naming feature, HLLAPI (High-Level Language Application Program Interface), and supports both character and graphical interfaces.

IBM Mainframes still contain over 70% of the key corporate data. Legacy data access is often achieved through the execution of mainframe applications with a 3270 interface. Cleo’s products have been designed to quickly facilitate the integration of 3270 mainframe access into any application using either our legacy HLLAPI interface or our Transaction Designer.

The Transaction Designer is a modern programming tool that supports the .NET, Visual Basic, Java and Visual Studio development environments. The Transaction Designer allows the developer to quickly develop error free programs using “transactions” rather than detailed API calls. A typical transaction set for a financial application would include: “get account balance”, “get next check” and “get last deposit”.

Cleo’s TN3270 / 5250 also supports Web Services interfaces via XML.

In addition to reliable products, Cleo’s technical staff is outstanding. Often mainframe communication expertise, especially with the organization’s older applications, is in short supply. With an average of over ten years experience in mainframe communications, Cleo’s support team is always available to support your pre-sales, installation and/or development needs.

If your company requires communications between IBM mainframes and your UNIX system, Cleo TN3270 / 5250 provides the emulation tools and advanced options that will put information in the hands of those who need it..
