8-Channel ACC Multiplexer Sessions
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.
The X.25 Traffic Analysis
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
