REQUIREMENTS/SPECIFICATIONS
This chapter describes cable requirements, power requirements, and operating specifications for the TRXI. Be sure that you read this chapter before you install the TRXI. Your network must meet the requirements and conditions specified in this chapter to obtain satisfactory performance from this equipment. Failure to follow these guidelines could result in poor network performance.
2.1CABLE 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
