Communications with Hierarchical SNA Networks

In traditional hierarchical SNA networks, remote terminals access centralized mainframe applications across a network.

This model uses the information display protocol for IBM mainframe computers known as 3270. This protocol facilitates conversations between the mainframe and devices such as terminals, printers, and controllers. SNA Server can provide access to these mainframe resources through the definition and assignment of 3270 LUs.

Once you have established the physical connection from SNA Server to the mainframe, you need to determine the types of 3270 connectivity that your users need.
