SNA direct connections
The System i™ platform supports frame-relay connections to remote systems that support the Systems Network Architecture (SNA) direct format. In this format, the frame-relay packets encapsulate the SNA data.
The following figure shows an example of SNA direct connections to a remote System i platform, a 5494 Remote Control Unit, and a 3745 Communications Controller on data link connection identifiers (DLCIs) 22, 23, and 24.
