Definition 4. - Short for
Digital Subscriber Line, DSL technologies use sophisticated modulation schemes to send data over the copper wire used for your phone connection and is considered high speed or broadband Internet access.
Definition 1. - This is technology that uses ordinary copper telephone lines to provide Internet speeds ranging from 1.5 to 9 Mbps--speeds that are 30 to 50 times faster than a regular 56-kbps dial-up modem. DSL also allows users to receive voice and data simultaneously, since the signal is carried on a higher frequency than normal telephone communications. xDSL refers to all types of Digital Subscriber Lines, including:
ADSL: Asymmetric Digital Subscriber Lines SDSL: single-line digital subscriber lines HDSL: high-data-rate digital subscriber lines VDSL: very-high-data-rate digital subscriber lines.
Definition 2. - A method for moving data over regular phone lines. A
DSL circuit is much faster than a regular phone connection, and the wires coming into the subscriber’s premises are the same (copper) wires used for regular phone service. A commonly discussed configuration of DSL allows downloads at speeds of up to 1.5 megabits per second. This arrangement is called an ADSL: Asymmetric Digital Subscriber Line.
Definition 3. - Technology that dramatically increases the digital capacity of ordinary telephone lines. The distance from the customer to the telco central office determines DSL speeds. Asymmetric DSL (ADSL) is for Internet access, where fast downstream is required, but slow upstream is acceptable. Symmetric DSL (SDSL) is best for connections that need high speed in both directions. DSL provides "always-on" operation. At the Central Office, DSL traffic is aggregated in a unit called the DSL Access Multiplexor (DSLAM) and forwarded to the appropriate
ISP or data network. DSL can compete with cable modems in bringing multimedia and 3-D to homes and small businesses.

| Let them have DSL! |

DSL has been hailed as a great solution for residential broadband needs. You may have heard this term from friends and neighbors when talking about their fast internet connection. It's true, DSL is much faster then a dial-up internet connection, but is it all it's cracked up to be?
With speeds of up to 140 times faster than dial up internet access its definitely fast but the problem is you don't always get the advertised speed. You
DSL connection is highly dependant on your distance from the phone company. If you're over 5,000 feet your signal will begin to drop off and your connection will be degraded, i.e. slower speed. At about 15,000 feet from the phone company (3 miles) your signal will completely cut off.
The second problem with DSL
is the fact that it's highly over subscribed. Oversubscription means that many people are pulling from the same resource. During the afternoon when people are at work there may be plenty of bandwidth to have, but in the evening when everyone is looking up the news, going through e-mail, or shopping online, access tends to be strained. Many people pulling from the same limited resource will find that there's only so much to go around. What does this mean to you? Slow speeds! It's interesting to note that DSL companies lampooned cable internet access as being shared by the neighborhood. Commercials displayed neighbors at each others throats for overusing the connection because it affected other's use. The irony of the commercials is that DSL users suffer from the same problem of common access. It's a great solution, but don't let them fool you….It's not perfect!

| An Analysis of Earthlink DSL Offerings |
|
Written by - Amy McMillen, Staff Writer
The first non-AOL internet provider I ever had was Earthlink. Their stock rose with the rest of the brand new
ISPs of the late 1900's. The sky was truly the limit.
However, as the internet buble burst in 2000, many companies who provided internet access with equipment purchased with investor dollars were left holding the back with huge networks and no one to fill them.
Earthlink DSL was differeint - they saw the need to diversify into high-speed internet access and other cusotmer-friendly value-adds, like Spam Blocker and Adult Controls.
Fast-forward to 2004, where we see Earthlink becomming the leader in DSL - and - Satellite internet access. The demand for high-speed access has never been greater - and by virtue of their carefull planning and listening the collective voice of their customers, Earthlink has vaulted itself into the lead in the race for number one residential high-speed access provider.
In particular, EarthLink made significant inroads in the broadband arena by signing an expanded
Digital Subscriber Line (DSL) agreement with
Verizon, launching
DSL service in Qwest's territories, and teaming up with Progress Energy to conduct a limited Broadband over Power Line (BPL) trial in North Carolina. EarthLink was also encouraged by the March 31, 2004 decision by the United States Court of Appeals for the Ninth Circuit not to revisit its earlier ruling that cable modem service contains a telecommunications service. If upheld, this decision will help open cable
broadband networks to competition, thus enabling EarthLink to offer high speed service over additional cable networks.

Most of us have been taught that by cutting out the middle man we can save money, but is that all you save? When it comes to
internet access and
phone service working with the incumbents or Baby Bells is a mixed bag. Certainly there are competitive companies that can give you the same or
better phone service than the Baby Bells which suffer from years of a monopolistic market but is it the same for
internet service?
DSL service is actually quite different than phone service. Besides the obvious difference of one being data and one being voice, competitive carriers generally use their own equipment which is kept at the phone company's facilities. In this case, asking your phone company to make changes to your service is dependant on your phone company and depending on how smoothly they run their operations you could have a very pleasant experience. Internet service, however is different. Many baby bells resell their service which is then sold under a different name. You may be buying internet access and not realize that you're really buying
Qwest DSL under another name.

In cases where companies purchase
Qwest DSL and resell it under their own name, many of the advantages of changing carriers disappear. If the carrier does not own their equipment they will need to contact the provider to make any changes and as they are not the provider you have added another layer of complexity to any request you may have. Is it really worth the $5 or $10 you're saving by going with a competitor? Often times it's not. Think about cutting out the middle man when looking for
internet service. If you know the company is simply reselling
Qwest DSL, why not just go with the source?
