DSL, short for Digital Subscriber Loop or Line, is a high-speed Internet connection that uses telephone lines. It uses a higher frequency than voice transmission so you can use your phone and access the Internet at the same time.

DSL service in Maine is available in most areas that are within 3 miles of a provider's central office. DSL download speeds range from 256K per second to 24MB per second depending on the type of technology and distance from the provider's central office.

DSL is set up by installing a DSL modem or router that connects to a phone jack. To prevent feedback and noise, a filter is placed on the phone line to block out the high frequencies used for data transmission.

There are various types of DSL services in Maine. Most DSL services are geared toward business, which may include email, static IP addresses and web hosting. Some types of DSL are ADSL, SDSL, and IDSL.

1. ADSL (Asymmetric Digital Subscriber Line) is most likely what you'll get if you order residential DSL service in Maine.

2. SDSL (Symmetrical Digital Subscriber Line) offers the same transfer rates for downloads and uploads.

3. IDSL (ISDN DSL) is a digital service that can travel farther than other versions.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Keep in mind that most Maine DSL providers are resellers and do not own the telephone wires. They usually provide more competitive pricing and better business packages than the major telecoms. However, since they don't own the lines, it can take longer to resolve service issues.
• •  Find out whether a providers offers a free router with DSL service in Maine. DSL can be routed across your network, but speed will be reduced as more people use the connection. Many DSL routers include firewall and routing services. Consider upgrading your router if it doesn't meet your needs.
