Communication Between D-Series and G-Series
Systems
Figure 1-4 shows an OSI stack running on a G-series system communicating with
another OSI stack running on a D-series system. The NSP on G-series can be X25AM,
TCP/IP, or PAM; the NSP on the D-series can be X25AM, TCP/IP, or TLAM.
Some Expand networks may contain a combination of D-series and G-series systems. It
is possible that the application, OSI/AS, OSI/TS, and either X25AM, TCP/IP, or TLAM
or PAM can be running on different nodes.
