The PAM Subsystem’s Role Within the System
(TRSA) provide the LAN connections on NonStop S-series servers and Integrity
NonStop NS-series servers.
The PAM Subsystem’s Role Within the System
The PAM subsystem consists only of software processes and interfaces and uses the
services provided by the SLSA subsystem to access the Ethernet and token-ring LANs
connected to the NonStop S-series server and the Integrity NonStop NS-series server.
Figure 2-1 shows the components of PAM and its relationship to other
data-communication subsystems. The components and related subsystems are
described after Figure 2-1.
