To connect to an STP MAU, attach the DB9 end of a Token Ring adapter
cable to the Token Ring module’s DB9 connector. Attach the Media
Interface Connector (MIC), on the other end of the cable, to any port
except the Ring-In or Ring-Out ports on a STP MAU. The Ring-In/
Ring-Out ports are used for interconnecting MAUs. Refer to the example
shown in Figure 2-2.
