Single TSP Process Supporting Multiple X25AM Lines
In this configuration, multiple X25AM lines are controlled by a single TSP process; one
or more TAPS processes use the single TSP process. Figure 4-5 illustrates this type of
configuration.
Since transport connect requests can arrive on any of the lines at any time, there must be
at least one transport attach outstanding on one of the TSP subdevices for each X25AM
line.
