CABLE SPECIFICATIONS
 
The basic concept of a token ring is a set of Trunk Coupling Units 
(TCUs) connected by trunk cabling. You can extend the trunk cabling 
by installing TPIMs into the TRXI’s RI/RO ports. TPIMs have 
embedded repeaters and provide trunk connections for UTP, STP, 
Multimode Fiber, and Single Mode Fiber cabling. 
You attach stations to the TCU lobe ports with lobe cabling. Figure 2-1 
shows the various ports and cables.
