| Telecom Fundamentals In this module, we’ll ensure you have a solid foundation in the fundamental ideas of telecom: The elements of a circuit; Terminals, clients, servers and peers; How bits are represented on fiber with pulses; and How bits are represented with modems on wireless, cable TV and DSL Then we’ll understand how a circuit's capacity is shared to carry many users’ traffic on common facilities: Frequency Division Multiplexing, Time Division Multiplexing, and Bandwidth on Demand: efficient sharing, involving packets, routers and overbooking the network core.
