This course covers the DDR process by which a link is created on demand. As traffic needs to cross the WAN, a circuit is completed from the source router to the destination, allowing the traffic to cross. DDR circuits are useful when you pay for access based on the amount of time the circuit remains up. The second part of this course examines broadband technologies. A cursory look at direct broadcast satellite (DBS) and fixed wireless providers is followed by more on cable modems. Four wireless segments: local multipoint distribution service (LMDS); multichannel multipoint distribution service (MMDS); industrial, scientific, and medical (ISM); and unlicensed national information infrastructure (U-NII) bands are also presented.
