Subsystem Architecture
SUBSYSTEM ARCHITECTURE
The TR3271 subsystem consists of one process controlling one
line. However, the subsystem can be combined to provide a pass-
through function between AM3270 terminals and a host by means of
TR3271. Figure 1-1 illustrates the architecture of the TR3271
subsystem and the various interfaces to the subsystem.
