Data Highway on Broadband Configuration
Broadband cable and modems replace daisy-chained twinaxial media and
offer a greater distance between nodes, as well as multiple networks
coexisting on one cable. Figure 2.1 shows a typical DH on broadband link
configuration where KRFs create a single DH broadband link.
