    CHAPTER 1 INTRODUCTION The MCC-16 Media Conversion Center is a 16-slot modular chassis that holds up to 16 Conversion Modules (CMs). The MCC-16, shown in Figure 1-1, can change twisted pair switch ports to different ports and/or media types. It is designed for switches and can convert between Ring In (RI), Ring Out (RO), lobe, and station ports, using twisted pair or multimode fiber optic cabling.
