Figure 1-1 shows an overview of Exchange/SNA and the other major components
required for RJE applications in an SNA environment. Note the inclusion of a
communications controller between the Tandem system and the host system. In most
SNA environments, a communications controller, such as an IBM 3704/3705
controller, performs network management and communications for the host system.
