TPS^®/SNA Primary and TPS^®/ SNA ( Systems Network Architecture ) combine to create a “Virtual SNA Mainframe” software environment on a UNIX^® System. TPS^®/ SNA Primary enhances the flexibility of TPS^®/ SNA by enabling a single UNIX^®-based system to support upstream host PU type 4/5 connections to any downstream PU type 2.0 system ( such as a 3270 device ) or to a host PU4/5 system using Cross Domain support. Standard SNA software implementations in the UNIX^® environment, including TPS^®/ SNA, supports traditional PU type 2.0 / 2.1 connections to host PU type 4/5 systems and PU type 2.1 connections to peer-to-peer networks ( APPN ). TPS^®/ SNA Primary offers dependent LU support for LU type 0, 1, 2, 3, 4, and 7. Data link or connection types supported include: SDLC, Token Ring, Ethernet, and Data Link Switching - DLSw ( Switch-to-Switch Protocol ).

TPS^®/ SNA Primary can be used with TPS^®/SNA to simulate a ‘Virtual SNA Mainframe’. Ideal for company looking to replace their mainframe or write customized applications. With TPS^®/ SNA API support, TPS^®/ SNA Primary is an excellent fit for developing SNA applications.

PRODUCT POSITIONING

TPS^®/ SNA Primary provides the basis for an easy migration from host environments to UNIX^®. It is an ideal solution when organizations are:

• Rehosting - moving mainframe applications (Batch and CICS) to a UNIX^® environment
• Needing to preserve their investment in existing PU2.0 ( 3270 ) devices
• ATMs utilizing TPS^®/PCA
• Providing PU4/5 support for customers dialing in from downstream PU2.0/2.1 connections or PU4/5 host systems requiring Cross Domain support
