Now, you have two major choices here -- one is to get your DSL connection modem through a third party and the other is to get one from your own ISP provider. Got more up to ,000 to spend and want a DSL modem that can handle more than one computer at a time? Many provide self-troubleshooting software, but if that doesn't fix the problem you're looking at paying for a service call. One broadband DSL service provider will usually offer all three flavors of broadband. Now, you have two major choices here -- one is to get your DSL connection modem through a third party and the other is to get one from your own ISP provider. The DSL ISP is responsible for maintaining your connection to the internet, just like a dial-up provider would be.

Essentially, speed shaping lets the service provider slow down the delivery of data to your modem when you go over your limit. To computers, it's a binary code that spells out where your computer is located geographically and who your DSL ISP is. Most people sign up for DSL because you get a much faster connection than with dial-up internet service.

What's the 'Broad' in Broadband DSL?


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.
