ADSL2[edit]

Can anyone add coverage over ADSL2, or ADSL2+?

I capitalized Ethernet. Ethernet is always capitalized. --imars 09:31, 22 Nov 2004 (UTC)

This page could use an explanation of the difference between fast channel and interleaved DSL. I don't know enough to write it myself. mvc 19:48, 8 August 2006 (UTC)[reply]

ADSL2 has it's own article now. ~Kvng (talk) 16:22, 8 May 2023 (UTC)[reply]

Cut[edit]

I cut this:

Some of the common "DSL Killers" are:

Bridged taps
Load coils
"SLIC" boxes, or splitters, where copper capacity is increased by extending with multiple fibres. DSL can't travel over fibre, and most telephone companies choose not to offer fibre connections to residential customers.
"DACS" boxes, where two baseband analog telephone lines are multiplexed over a single copper pair using ISDN-like technology to connect to the central office. Neither of the multiplexed lines is then usable for either DSL or ISDN service, as there is no metallic high-frequency path available. Where the central office connection is demultiplexed to analog connections, there is the added disadvantage that standard analog modem speeds are also reduced significantly.

As I'm not sure what its trying to say. You obviously need a continous copper line from CP to CO and I think this muddies the waters. Alex

Caps[edit]

I see that the titles Asymmetric Digital Subscriber Line, Integrated Services Digital Network, Asynchronous Transfer Mode, Asymmetric Digital Subscriber Line, and Digital Subscriber Line are all capitalized. These articles tend to have lots of incorrectly capitalized letters in the body of the article, and that makes me suspect that someone may have written them as capitals under the incorrect impression that the Wikipedia convention is to capitalize words in article titles?

dsl inventor[edit]

I am aware DSL technology started in Bell lab at around 1988. However, i can't see to find the guy behind the technology. A used google to try and look it up, but it looks like hundreds of people are claimimg dsl as their invention. This make it all the more important to find the real inventor and give credit to the right guy. I am aware that all inventions are progressive work and that Claude Shannon did most of the theoritical work, but then humans like personalizing achievement and hence the need of the guy who put things together and called it dsl. GITLIN, Richard claim to be one of them in this article [1] Anyone know the history behind this? (Hint)His 1st name is Aaron...and lives in San Diego county..

History[edit]

There should be more on the DSL History. Like how it was at one point intended to carry Video-On-Demand. linky

DSL history - sources?[edit]

The first paragraph on the DSL page makes some claims that I haven't heard elsewhere. Some sources are needed for it(news reports, historical studies, etc.). It's good writing, and interesting, but it needs to be sourced.

The paragraph: "Its origin dates back to 1988, when an engineer at Bell research lab deviced a way to carry digital signal over the unused frequency spectrum. This allows ordinary phone line to provide digital communication without blocking access to voice services. Bells management however were not enthusiastic about it as it was not as profitable as renting out a second line for those consumers who prefered to still have acess to the phone when dialing out. This however changed in the late 90s when cable companies started marketing broadband internet access. Realising that most consumers would prefer broadband over a second dial out line, Bell companies rushed out the DSL technology that they had been sitting on for the past decade as an attempt to slow broadband internet access uptake." - diff (Also posted on User talk:Wk muriithi) JesseW 19:48, 6 Apr 2005 (UTC)

wk muriithi replied on my talk page saying he got it from "Crafting and Executing strategy 14th edition by Arthur A. Thompson Jr.". If someone who has a copy could verify this, and add it as a footnote(use Wikipedia:Footnote3 style) that would be great. Thanks for replying, Wk! JesseW 05:34, 15 Apr 2005 (UTC)

External link[edit]

First external link is dead.

Internet Speed Calculator[edit]

There should be a calculator where you input a filesize and it outputs the time required to download/view that file on different internet speeds.

There are plenty online. -Omegatron 02:50, August 22, 2005 (UTC)
