Comparison of Regular and Naked DSL
In regular DSL, a cable runs from the telephone switch to a piece of equipment called a Plain Old Telephone Service (POTS) splitter. This splitter separates the DSL and voice bands. Thus the customer will have a dial tone, which allows them to use the telephone line as a regular land line while they are using it to access the Internet on their computer. A cable carrying both services runs from the splitter to the cable head, where it continues on to the customer on outside plant. (See DSLAM.)
In naked DSL, there is no cable from the telephone switch to the POTS splitter. Thus there is no dial tone on the line. However, the customer could still use the line for regular telephone service through Voice over Internet Protocol (VoIP) or a Competitive Local Exchange Carrier (CLEC) instead of the Incumbent Local Exchange Carrier (ILEC).
Naked ADSL2 and ADSL2+ provisioned with "all digital mode" Annex I or Annex J can achieve additional 256 kbit/s of upstream data rate.

Famous quotes containing the words comparison of, comparison and/or regular:
“We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.”
—Ralph Waldo Emerson (1803–1882)
“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“They were regular in being gay, they learned little things that are things in being gay, they learned many little things that are things in being gay, they were gay every day, they were regular, they were gay, they were gay the same length of time every day, they were gay, they were quite regularly gay.”
—Gertrude Stein (1874–1946)
