What is DSL?. .

DSL stands for Digital Subscriber Line and is a relatively new technology that allows high speed connections over plain copper telephone wires (twisted pair). However, just because DSL uses telephone wires to connect your home or office to the Internet doesn't automatically mean that everyone that has a telephone can connect to the Internet via DSL. DSL provides your home or office with a dedicated connection to the Internet, much in the same way that a cable modem does. A DSL connection provides anywhere between 144 Kbps and 1.5 Mbps of bandwidth. DSL is broadband based technology, which means that the data to-and-from your home or office travels over the wires via a high-frequency carrier signal. The carrier signal originates from a Telco's Central Office, and dissipates over distance, much like the radio signal from your favorite AM radio station starts to deteriorate the further you drive out of town. The maximum distance that you can be from the Telco's Central Office is 15000feet (which is just under 3 miles). If your home or office exceeds this distance, then the best connection speed that you will qualify for is 144Kbps (which is still faster than 2 ISDN B channels). DSL's speed and quality also depends on the quality of the wiring installed in your home or office. If the quality of your wiring is poor, then you probably won't get much more than 128 Kbps data transfer rates. If the quality of your phone lines are excellent, then you could qualify for speeds of up to 1.5 Mbps (equivalent to T1 speeds), provided that your home or office is close enough to the Telco's Central Office.

Types of DSL

There are currently three different types of DSL connections available. They are:
* ADSL (Asynchronous Digital Subscriber Line)
* SDSL (Synchronous Digital Subscriber Line)
* IDSL (Integrated Digital Subscriber Line)
ADSL provides faster download speeds than it does upload speeds. SDSL provides equal download and upload speeds. IDSL provides integrated ISDN technology so homes or office that are more than 15000 feet away from the Telco's Central Office can still obtain a DSL connection (although at slower speeds).

What type of DSL is for me?

ADSL is generally best for home and small business use. This is because of its larger data rate downstream. This means that the typical user will be able to download faster than they can send data. Which, is very typical of most home users. SDSL is primarily for customers who require larger bandwidth or plan to have multiple users on the Internet. SDSL is a dedicated bandwidth while ADSL is a best effort bandwidth. IDSL is generally used when ADSL or SDSL services are unavailable due to distance limitations from the phone company's Central Office (CO). With IDSL, you can still take advantage of DSL's blazing speeds and dedicated connection, even if you're out of range of the other DSL services. The trade-off using IDSL is your connection is limited to 144Kbps - the low end of the DSL spectrum.

What does DSL Cost?

DSL service and availability but pricing in some areas has been very aggressive. Prices differ significantly depending on the service provider and surrounding area but we here at The DSL Pros have set pricing for all customers no matter where you live. Generally, you must pay for the cost of installing your DSL line, equipment fee and the monthly service charge. We are here to get you the best deal possible, to get prices you must go to our information page.

INSTALLATION QUESTIONS

I Want DSL. What do I do first?
The first step here is to fill out our online form. From here the order process begins. The phone company will first determine if you address is able to support DSL. Then if you are close enough to the Central Office (CO) a line test is run to determine if your existing copper wires will be able to handle the bandwidth needed for DSL transmission. If all goes well your line will qualify and the phone company will set you up. In order for ADSL for example to be installed the phone company will place a splitter in the box at your location. This splitter will enable you to retain your voice service while using ADSL.

What hardware does my computer need for DSL?
Typically, all you will need to begin using your DSL line is a Network Interface Card (NIC). The DSL modem/router will connect to the DSL digital telephone line, and to your NIC or a network hub.

How close to the phone company must I be?
Three miles(18,000 ft) is the longest acceptable distance from the Central Office. Beyond that, the data rates DSL offers begin to degrade. Usually this distance is large enough to include most people in any particular area.

Can The Phone Company Use My Existing Wires, Or Do They Need To Install New Copper Wire?
This question all depends on the results of the line test. If the location fails to support an acceptable data rate, this means that your existing lines may not work with DSL. However, new lines can be installed just like an ISDN installation.

I Already Have ISDN. Can I Use DSL Also?
Yes, if you go through the steps mentioned above. But, your ISDN line will not support both DSL and ISDN. Meaning that you must have one set of wires for each service. Now, if you want to drop ISDN service in favor of DSL you can use the wires that were installed for the ISDN line. In fact, this is preferable because the ISDN lines are newer installations and more able to support DSL bandwidth.

DSL HARDWARE

Does DSL Require Special Hardware?
DSL needs a few important hardware items for it to correctly work. An existing, or new, telephone line will be converted to digital to carry the DSL traffic. Also you will be provided with a DSL router or modem. On the Phone Company side, every CO will have a device called a DSLAM. This will directly connect you to the backbone network of your ISP. Other than that there are really no other special hardware devices used for DSL. Of course, some circumstances may change hardware requirements.

Can I Purchase My Own DSL Modem?
Yes, but the cost is prohibitively expensive for the home user. All of our deals with the ISP's include installation of a router or modem provided by the ISP. This way, you are guaranteed that it will interface with the DSLAM on their end. Larger businesses might be interested in their own DSL equipment in if they have special needs for there network.

I Have A Network And Want DSL Access. What Do I Need To Get?
Once you have your network up and running, DSL connectivity is quite easy. Your DSL router will have an out put to a LAN (or a single computer with a NIC). Just plug it in and you are connected. However, you may need to change IP addresses within your network so every node will be able to access the line simultaneously.
