If asked to describe DSL technology, which statements would help the user develop a better understanding of the technology? (Choose three.)

• DSL is available in any location that has a telephone.
• ADSL typically has a higher download bandwidth than available upload bandwidth.
• In home installations, a splitter separates the ADSL and voice signals at the NID, allowing multiple ADSL outlets in the house.
• DSL speed can exceed the speed available with a typical T1 line.
• Transfer rates vary according to the length of the local loop.
• All varieties of DSL provide the same bandwidth, although they use different technologies to achieve upload and download.

Explanation: The different varieties of DSL provide different bandwidths, some with capabilities exceeding those of a T1 or E1 leased line. Within the variety of DSL, transfer rates are less as the distance from the central office decreases. ADSL is asymmetric DSL, which provides higher download bandwidth than upload bandwidth.
