Dial-up vs. DSL

July 10, 2009 at 12:45 pm (Dial up, DSL) (, , , , , , , )

If you are interested in switching to DSL Internet services, you may be curious to know what DSL is all about and how it compares to dial-up. For the purpose of this comparison, we will assume that by DSL, we are talking about ADSL, the typical DSL connection available that uses a phone line to connect. Here are a few of the basics.

For starters, dial-up and DSL both connect using your land line phone line. Simply put, a dial-up modem converts the analog communication your phone line uses into digital information needed for your computer. The same thing happens on your phone company’s end. Their modem converts the from digital to analog so it can travel on the phone lines. DSL, on the other hand, uses the same wires that your analog phone line used and bypasses the digital-analog-digital conversion dial-up must use.

Therefore, DSL transmits information much faster than dial-up, and works at a higher frequency (higher than can be detected by the human ear), and by doing so, it does not effect the analog communication (phone conversations, etc.) on those same lines.

The most obvious difference, other than the speed, is the price. The total monthly cost of dial-up is between 10 and 20 dollars a month with little or no additional fees including set up or equipment fees. DSL has a monthly fee somewhere between 20-100 dollars a month (based on speed desired and location), not including the price of equipment, installation, and other fees such as repair plans, technical support, or contract fees.

Most computers have a dial-up modem already installed on the computer, so there aren’t typically many equipment costs associated with dial-up. Other than a land line and a phone cord, that is the extent of the “equipment” and “installation” costs for dial-up.

Availability and transportability are two categories where dial-up exceeds DSL. Connecting to the internet with most dial-up services is available to any computer that has a land line phone. It is not confined to the home where the DSL modem is installed.

DSL is only available in very limited areas. DSL is rarely available in rural areas because they are too far from the phone company’s central office. The choices of connection speeds on DSL could cut in half based solely on your locations. Often, a few hundred feet means the difference of DSL or no DSL for suburban homes.

DSL and dial-up can be provided both by your phone company or through your phone company. While you can set up nearly any dial-up service with any analog phone service, DSL is usually only available with your phone company or a DSL company that partners with your phone company.

Many phone companies will not let any other DSL company use their phone lines, so this could even further limit or prevent you from getting DSL. If they do, further problems can occur in the process of communication during the activation period and the resolving of technical issues. Even with no complications, DSL usually takes at least several days to set up.

Dial-up has a very simple set up procedure that takes about half an hour or less (unless you are mailed a setup CD, which is often not necessary). Since it is so simple to set up, you can easily move the connection, set up multiple connections, and take your service with you when you travel or move. Rarely does your phone company need to be involved or even notified, other than to make sure your access number is a local call.

DSL is a fast, dedicated connection for those who require it for gaming, downloading, and streaming of videos, etc. Dial-up excels in price, availability, and simplicity for people who need to save money or don’t have many other options.

DSL: A Basic Introduction

June 23, 2009 at 11:34 am (DSL) (, , , , , , )

What is DSL? An acronym for “Digital Subscriber Line”, DSL is a type of broadband connection that typically connects through your home phone line. Broadband is any type of Internet connection that is faster than dial-up, or narrowband. DSL does inhibit the use of your phone line, allowing you to connect to the Internet and receive phone calls at the same time. DSL is an always on connection, so you are constantly connected to the Internet.

How does DSL work? DSL is usually provisioned by a local phone company or a company that partners with a local provider. The connection is typically established between your phone company’s central office, your analog phone line, and a DSL modem. This type of connection maximizes the use of telephone lines by eliminating the conversion from digital to analog, which is required for telephones, or digital to analog to digital, which is required for a dial-up connection.

Do I need a phone line to get DSL? Typically, yes. DSL is usually provided through your existing land line phone. This type of DSL will not work on a digital phone service (i.e., VIOP, cable phones, cell phones, etc.). Dry-loop DSL, or naked DSL is available in some areas and does not require an active phone service. You should check with your DSL provider for more information.

How fast is DSL? Your connection speed is typically directly affected by your proximity to the telephone company’s central office, which is why DSL is often not available to rural homes. The closer you are to the source, the higher speed connection you can recieve. DSL speeds usually ranges anywhere from 500-6000 kbps (kilobits per second). For a comparison, dial-up is usually a 20-40 kbps connection. Even the slowest download speed on DSL is sufficient for normal web-surfing, email, and most audio and video streaming, but if you are planning on using more than one computer, play online video games, or download large files frequently, you will want to get one of the higher speed plans available.

How much does DSL cost? Again, this depends on where you live and what is available in your area. Prices can range from $12-100 a month, including the cost of equipment, depending on what speed you want and what company provides your service. Keep in mind that the price you see advertised in brochures or online may not be available for you or is an introductory rate that will increase after the first few months. Also, if multiple plans are available, low prices are for slower, sometimes unsatisfactory connection speeds. Depending on your purpose for buying DSL, you may need to find a plan that offers higher speeds at a higher cost. Also watch for additional fees, cancellation fees, contracts, and extra equipment costs when determining your final price for your service.

How do I install DSL in my home? DSL comes in different forms for different purposes, so the installation process will differ. For most home DSL plans, you can expect to wait 5-10 business days for your phone line to be provisioned for DSL and you will need to buy or lease a DSL modem. You will also need to set up filters, splitters, a few wires and cables, as well as a router if you want to use a wireless laptop. You can refer to your DSL provider for more details and installation instructions.

The first step to connect with DSL is to find out whether it is available in your area. You can search online or check with your local companies for more information. When you do, find out if what companies provide DSL specifically to your house, then check for prices, speeds, contracts, and other plan details to find the plan that’s best for you.
