Answer:
False
Explanation:
DSL(Digital Subscriber Line) :-It is a technology in which user gets high bandwidth connection over ordinary telephone lines.
This technique uses data modulation to achieve higher throughput over the telephone lines.Telephone lines carry voice signals over a small range of frequencies between 300 and 3300 Hz. So the frequencies that are higher are unused and available for data transfer.
DSL connection uses a modulation technique based on amplitude or phase modulation. With the help of modulation techniques DSL uses these unused higher frequencies.It uses frequency range higher than 300 to 3300 hz.
