How to Evaluate a DSL Provider

Depending on where you live, you may be able to choose from one or more DSL Internet service providers (ISPs). DSL, or digital subscriber line, uses part of your normal phone line as a "dedicated" data line that connects directly to an ISP. Access speeds with DSL can vary, but they are typically at least five times faster than a 56 Kbps modem.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• DSL Lines
• Internet Service Providers

1. Find out what type of DSL service the ISP provides. If it is ADSL, find out what type of ADSL.
2. Find out the maximum speed possible (in MB per second) through the service. Ask about both upload speeds (the time it takes for you to transfer files to the Internet) and download speeds (the time it takes for computers on the Internet to transfer files to you). Upload and download speeds will be different.
3. Compare prices for relative speeds.
4. Find out what equipment will be installed.
5. Compare installation and setup fees, if any.
6. Find out when technical support is available. Look for 7-day, 24-hour support if you need it.
7. Compare additional ISP features such as Web hosting space, additional e-mail accounts, domain name aliases and other features, if you need them.
8. Consider your current satisfaction with the service, especially customer service, provided by your telephone company before choosing it to be your ISP.
9. Compare service-term commitments, if any.
10. Ask about potential rate increases.

Tips & Warnings

• The actual DSL line comes from your telephone company, regardless of whether you purchase service from them or another ISP. Your telephone company must evaluate your telephone line to determine if it can be used for DSL. (See the related eHow "How to Find a DSL Provider in Your Area.")
• Expect a maximum download speed of 1.5 Mbps and a maximum upload speed of 386 Kbps from a common type of DSL called "G.Lite." (G.Lite is slower than normal ADSL, or asynchronous DSL.) Keep in mind, though, that phone companies usually only guarantee speeds of 383 Kbps for downloads and 128 Kbps for uploads.
