Quizplus · Accepted Answer

Digital subscriber line (DSL) is a high-speed carrier service that uses ordinary phone lines to send and receive data. It operates on a different frequency than voice calls, allowing for faster data transfer speeds. An analog modem operates at a slower speed and is not considered a high-speed carrier service. Code division multiple access (CDMA) is a digital cellular technology, and a cable modem uses cable lines rather than phone lines.
