What is DSL?
DSL (or Digital Subscriber Line) is a modem-based technology that allows high-speed data transfer over existing copper telephone lines.   Downloads can take place up to 50 times faster versus a traditional 28.8K modem (see chart below):

Where is DSL available?
DSL technology is available in a growing number of communities throughout Atlantic.Net’s coverage area.  Since DSL is a distance-sensitive application, customers typically must be at most 12,000 to 15,000 feet of a telephone company central office (CO) to be able to use it.  In some cases, Atlantic.Net can take advantage of other technologies to deliver DSL up to 17,000 feet from a central office.

Atlantic.Net works with a number of different DSL providers to be able to offer the technology in more areas.

I've heard of ADSL, SDSL IDSL, what's the difference between them, and what does Atlantic.Net support?
ADSL: Asynchronous Digital Subscriber Lines provide different data transfer rates in different directions. Typically, download speeds are faster than upload speeds. ADSL is not normally supported by Service Level Commitments (SLC), which means there is no formal guarantee for the quality of service. ADSL is best suited for residential applications like Web browsing and multimedia applications.

SDSL: Synchronous Digital Subscriber Lines offer the same data transfer rates in both directions. A much more reliable technology, SDSL is used primarily for businesses in connecting LAN's to the Internet and hosting server applications.

IDSL: ISDN Digital Subscriber Line service, in most cases, allows customers to use DSL technology outside of the normal distance limits, up to 17,000 feet from a CO. Speeds are comparable to ISDN, or about 128K each way.

Atlantic.Net supports all three types of DSL.

Absolutely, DSL “piggybacks” over existing telephone lines, but does not interfere with voice traffic.

Atlantic.Net offers a variety of ADSL service plans.  Why are there so many variations in DSL packages that Atlantic.Net offers?
Atlantic.Net offers a DSL solution for everyone.  To insure the broadest availability, Atlantic.Net has established relationships with a variety of DSL providers.  DSL providers that Atlantic.Net works with have different capabilities, so that’s why we have the variation throughout our service area. The DSL option that is best-suited for you depends on your specific application and location.

Why should I choose DSL over cable?
DSL lines are dedicated to each location individually, while cable is a shared technology typically hooking up numerous locations in an area, like a neighborhood, over a single line (similar to a LAN).  For this reason, there are serious privacy concerns that still need to be addressed, and individual connection speeds will fluctuate dramatically depending on the usage of others on the line.

What does “always on” mean?
Unlike traditional analog modems, DSL connections are constant between the customer premise and the CO, so you don’t have to “dial-in” and wait for a connection to establish or worry about getting a busy signal.

What equipment do I need at my location to be able to use DSL?
The typical installation includes the following:

Customer Premise Equipment (CPE): This is the ethernet bridge or router.  Routers and bridges are other varieties of CPE, typically used for business applications.

In Line Filter: This plugs into the telephone jack at the customer location, and separated the signal from the voice signal

Splitter:  Allows a DSL modem and a telephone to connect to the same telephone jack.

Network Interface Card (NIC): Typically 10Base T, connects the DSL modem to the computer.
