DSL Is from the phone line right? What is ASDL? And does it come from your phone company or do they have to support it? Can you get on a regular home phone line. Or does it use a cable or cable motem? And do you have to have a dsl motem? I know broadband uses cable and cable modem that comes with service. I think. I never did figure this out I guess cause I only have phoneline. Can someone spell it out to me without too much trouble? I am about ready to upgrade and I am trying to learn about my optiions first. Thanks

DSL is digital suscriber line, and works with just a phone line. ADSL is Asymmetric digital subscriber line. ADSL is the newer technology and has a faster speed (bit rate) and requires an ADSL modem. It works with regular phone line too. There are no cable modems involved. You need a DSL modem for DSL. Your phone company might or might not offer either service. Go online to thier web site or call them. You can still use your phone with the same line and do not need to have two phone lines. I have DSL with SBC/ATT and have not had any problems. Cable requires a hookup from your cable company. You can also get broadband from a satellite company. Hope this helps...It can get confusing.

yes that helps. You told me exactly what
I needed to know! Thank you very much!

Give him the 'best response' mark. :D Anyway, ADSL can also be defined as "Asynchronous Digital Subscriber Line" (well, this is not what's mostly defined on yahoo if you search the term, but i learnt so), which like sigma said, faster than DSL.

ADSL, as another user pointed out, is Asymmetric DSL, which means that your download speed is faster than your upload speed. In most cases, it's two times faster

DSL is Digital Subscriber Line
ADSL Asymmetric DSL.
BOTH uses phone line.
DSL modem.
ADSL devides the available frequencies in a line on assumption
User will use internet for look at,or download much more information than they send.If the connection speed from internet to user is3/4 times faster than connection from the user to the internet than the user will get the most benefit.
So for you ADSL in Advicable as your choice.

DSL (Digital Subscriber Line) is a technology for bringing high-bandwidth, high-speed Internet access to homes and businesses over ordinary copper telephone lines. A DSL line can simultaneously transmit data and voice signals, and provides an ‘always on’ connection to the Internet.
while ADSL is the better modification or an added advantage over DSL.
ADSL (Asymmetric Digital Subscriber Line) is the most popular form of DSL for home users and Small to Medium Enterprises (SMEs).
ADSL is called "asymmetric" because most of its bandwidth is devoted to the downstream direction, i.e. sending data to the user. As most Internet use requires greater downstream bandwidth, only a small portion of bandwidth is available for upstream or user-interaction messages.

dsl means direct supply line while asdl is nothing.i hnnt heard anything about asdl.
Dsl and broadband are tow ways to get internet faster speed.broadband is much faster than dsl

ADSL needs a few important hardware items for it to correctly work. In order to separate voice transmissions from data over the copper line, a splitter would be installed outside the user’s home or office. The user will also be provided with a special ADSL modem.

Yes DSL is for dial up and ASDL is not. DSL you can get from your phone company, and you can use this on a regular home phone line. No ASDL is for broadband and they use a modem, and it has nothing to do with your phone line at all. Hopefully this helped you understand more.

Digital Subscriber Line :
(DSL, or Digital Subscriber Loop) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and telephone companies.
When two conventional modems are connected through the telephone system (PSTN), it treats the communication the same as voice conversations. This has the advantage that there is no investment required from the telephone company (telco) but the disadvantage is that the bandwidth available for the communication is the same as that available for voice conversations, usually 64 kb/s (DS0) at most. The twisted-pair copper cables into individual homes or offices can usually carry significantly more than 64 kb/s but the telco needs to handle the signal as digital rather than analog.
There are many implementation of the basic scheme, differing in the communication protocol used and providing varying service levels. The throughput of the communication can be anything from about 128 kb/s to over 8 Mb/s, the communication can be either symmetric or asymmetric (i.e. the available bandwidth may or may not be the same upstream and downstream). Equipment prices and service fees also vary considerably.
The first technology based on DSL was ISDN, although ISDN is not often recognised as such nowadays. Since then a large number of other protocols have been developed, collectively referred to as xDSL, including HDSL, SDSL, ADSL, and VDSL. As yet none of these have reached very wide deployment but wider deployment is expected for 1998-1999.

adsl is the main router for your broadband/triband internet connection..
im not really sure but most probably it is that...

hey mate i forgot to add the adsl is mostly connected to your phone connection

It is through a phone line and like others have stated ADSL is faster than DSL, like another user pointed out you might be able to get VDSL which is a signal aquired by satelitte and is much faster but also usually more exspensive, I used to be a TSA (Technical Support Agent) for DSL & ADSL.
