Cable Connectors
Medium Interface Connector (MIC)
The MIC, shown in Figure 4-3, is typically found on IBM Type 6 and 9
patch cables. It has the capability to loop the transmission path back
through the cable when it has been disconnected.

DB9 Connector
The DB9 connector, shown in Figure 4-4, is found on STP cables used for
lobe and trunk connections on Cabletron Systems Token Ring products. It
does not wrap as the MIC does upon disconnection from a device; that
feature is present at the DB9 port on the device instead.
