As outlined previously under “General Procedures”,
the 8-Channel multiplexer board was installed per the steps noted
in the ACC Multiplexer Hardware Installation Guide.
The base system and X.25 protocol software was installed and
verified per the steps noted in X.25/ACC Installation
and Configuration Guide. Following this the system was
restarted and the data analyzer captured traffic and activity on
the channels.

When the pdisplay program for the Data
Analyzer was started, the runc command
was used. This allowed for the dynamic creation of ZLU pairs on
which the analyzer would automatically run. The log of terminal activity
for this session appears as follows (new actions are in boldface):
