Understanding Digital Subscriber Line (DSL)

Exploring Digital Subscriber Line (DSL)

Digital Subscriber Line (DSL) is a technology that provides high-speed internet access over existing copper telephone lines. It is implemented over local loop UTP (unshielded twisted pair) which is the same copper wire used for traditional phone service.

DSL is not another name for ISDN (Integrated Services Digital Network) which is a completely different technology that provides voice, video, and data services over digital lines.

In addition, DSL is also not implemented over coaxial cables, which are typically used for cable internet service. Therefore, the correct statement is a, and the other statements (b and c) are incorrect.
