Make a list of what you actually want out of the Internet connection access and then list the pros and cons of both types of connection. DirectTV DSL: An Inevitable Step Towards Better TechnologyDirectTV DSL internet service is an inevitable step in the typical progression towards better technology. Once you install your cable for the TV you automatically get the best high speed internet, and it doesn't matter how close you are to the provider - you'll still get interference-free service.

The origin of DSL technology dates back to 1988; the engineers at Bellcore (now Telcordia Technologies) came up with a way to send digital signals over the unused frequency spectrum available on the twisted pair cables running between a telephone company's main office and the client's desired place. Cheap DSL Doesn't Mean Less QualityThe word cheap is often associated with inferior quality, so you might think with cheap DSL you get less service. Comparing DSL vs cable, it is often assumed that cable is much faster than DSL. Free online games have gotten much more elaborate than that solitaire program that came loaded on your computer. The best part is, you can still use the standard phone line.
Joining the world of high-speed internet access can be like getting lost in a strange country where you don't speak the language: IP, ISP, DSL, an endless stream of acronyms. In order, that's: internet protocol, internet service provider, and digital subscriber line!
Broadband DSL, on the other hand, is refreshingly straightforward. Think of dial-up internet service as trying to run a lot of water through a small pipe. Now take that same amount of water and toss it through a pipe as big around as a garbage can. That's broadband DSL.
Ok, I lied. Broadband DSL isn't that straightforward and there are some acronyms involved. I'll explain them below.
ADSL
If you have broadband DSL at home you most likely have this flavor. The 'a' stands for asymmetric. All this means is that downloading content (reading an email) from the internet is about three times as fast as uploading (sending an email, for example).
DSL providers set their networks up this way because studies have shown that it's the best way to optimize the speed of their connections. The speed of an ADSL broadband service ranges from 400 to 700 kilobits per second downstream, and 100 to 350 kilobits per second upstream.
SDSL
You can probably guess now what the 's' in SDSL stands for - symmetric. Businesses prefer broadband DSL that sends data up and down stream at equal rates, so you're likely to find this species of broadband hiding out at the office.
Depending on the broadband DSL provider data flies through these wires at up to 1.54 megabits per second.
IDSL
This is an acronym buried within an acronym. The 'I' stands for 'ISDN', which in turn stands for 'Integrated Services Digital Network.' Put that together with DSL and you get the redundant 'integrated services digital network digital subscriber line.' What a mouthful. Let's just stick with the acronym.
Broadband DSL providers turn to IDSL when dealing with customers who live far from the telecomm's home office. Digital signals typically degrade with distance. The other types of DSL peter out around 18,000 feet.
That's where IDSL comes in - its reach extends more than twice the distance of SDSL, since it uses fiber optic technology instead of the pre-existing copper wires used by the other types of DSL and regular phone lines. One broadband DSL service provider will usually offer all three flavors of broadband.
