Connecting a Segment Through the RI or RO Port

Figure 2-2 shows a network with IBM 8228-style media attachment units (MAUs) forming a single ring segment. You can create two ring segments by connecting one MAU to a TokenSpeed module through the RI or RO port on the MAU.

The remaining MAUs form a segment that is connected to the TokenSpeed module through a lobe port on the MAU.
