Figure 5-1 below shows the path availability across units.
In the above example, the user at Unit 1 would like to access computer 2H. There is
a valid path out of Unit 1 to accommodate that. However, all four paths in Unit 2 are
currently taken by the four local users. The only way the user in Unit 1 can access a
computer in Unit 2 is through
sharing
. He may view the video on any channel but will
not have keyboard or mouse control unless the Unit 2 user relinquishes control.
However, the Unit 1 user can access computer 3K independently, because there are
three open paths available in Unit 3. There is only one user in Unit 3, using computer
3B, taking one of the four available paths.
