The PSTN and Broadband on Copper Book PDF Summary
The PSTN and Broadband on Copper Before wireless and fiber, two copper wires were used for the physical access circuit for telephone and cable TV service in suburbs and cities. Today, these wires are also used to deliver broadband. In this module, we’ll understand how DSL broadband service runs on twisted pairs put in place for analog POTS telephone service; how cable modems move broadband on coaxial cable; and how both are delivered as fiber to the neighborhood then copper to the premise. To finish up, we’ll review digital on copper wires: LAN cables and T1s.
