The main problem with DSL is that it is distance dependent and must be all analog from the telecom central office to the customer premise. However, certain DSL setups can achieve 1.5 Mbit per second upload and download.

Cable is shared between multiple customers within a certian area whereas DSL is single-user to the CO. So, when a lot of people are surfing cable will most likely slow down more than DSL.
