Figure 7-5 Hierarchical Tree of Concentrators
Advantages
The tree of concentrators configuration offers many of the advantages offered
by the standalone concentrator, described on page 72; however, it allows a
much larger number of stations to be connected.
The cumulative length of the network is increased significantly because the
limitation on distance occurs between the end-station and the nearest
concentrator, and not between the end-station and the root concentrator.
