For each node you configure on the HP e3000, a corresponding
T2.0 or T2.1 node should be in the remote system configuration. Figure 4-1 “PU-SSCP Session Establishment ” shows how a session is established between
the SSCP on the remote system and the PU on the HP e3000 node (either
a T2.0 node or a T2.1 node). The remote system sends out a poll
on the data link, in the form of a Set Normal Response Mode (SNRM),
and continues to poll the link until it receives a positive response
from the HP e3000. The HP e3000 node is activated with the SNACONTROL START command (see Chapter 6 “MPE Commands” in this manual).
The SSCP then sends an ACTivate PU (ACTPU) request to the HP e3000
PU. SNA Transport, as the PU services manager, sends a positive
response back to the SSCP. The PU-SSCP session is now established.
