Answer: A - One of the primary and most crucial limitations associated with a DSL connection is its distance limit from the central office.

Key Takeaway: Although DSL is a very advanced technology, it has a very noticeable limitation in that the customer cannot be farther than 18,000 feet from the central office. The signals attenuate beyond regeneration and DSL providers normally restrict their clientele to within 18,000 feet of their central office. This distance limitation worsens with DSL connections at higher speeds. The customers need to be even nearer to the central office if they intend to have high-speed DSL connections around 6 Mbps.
