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.
