Quizplus · Accepted Answer

Digital Subscriber Line (DSL) is a technology that is used to transmit digital data over traditional copper telephone lines. It is a fairly recent approach to provide higher data transmission rates across traditional voice circuits in the local loop. DSL combines analog transmission and frequency division multiplexing, involves the use of a customer premises equipment (CPE), and uses a combination of amplitude and phase modulation to transmit data. Therefore, all of the above options are correct.
