In order to assist you with the DSL facts, we have provided you with the following DSL F.A.Q. section.

How does DSL Work?
DSL provides your subscribers with high-speed Internet access over existing copper telephone lines. No special wires are necessary; just the plain old phone lines that are already out there. DSL utilizes a bridge or router at the customer location, which connects to a Digital Subscriber Line Access Multiplexer (DSLAM) in the telephone company Central Office (CO). When your DSL line is ordered, you can lease or purchase your modem directly from us. We will ship your modem to your home directly. Please call 1-877-688-8127 for modem information and to Signup today.

The DSLAM is property of our partners, who lease space in the CO from the local telephone company to co-locate the DSLAM. The copper phone lines that connect to the modem at the end-user location are the property of the local telephone company. These companies lease a copper line from the telephone company and connect this leased line to the DSLAM in the CO, thus enabling the high-speeds of which DSL is capable.

Fast Access:
DSL allows you to send and receive data at speeds up to 1.5 Mbps. That’s more than 30 times faster than a 56 Kbps modem! DSL offers more than just fast downloads of e-mail, graphic files, Web pages and software. Additionally, DSL enables advanced functions like Web hosting, video conferencing, video streaming, virtual private networking and e-commerce.

Traditional DSL is available in the following speeds:
• 128 kbps
• 256 kbps
• 768 kbps
• 1 Mbps

Constant Connectivity:
In addition to providing the highest speeds possible over copper wires, DSL provides a dedicated connection. This means DSL connections are always on. There is no need for lengthy and slow dial-up to connect to the Internet because simply clicking an icon will put your customers online instantly. No busy signals, no dropped connections, no more dial-up frustration.

Multiple User Solution:
Multiple computers can be connected to a single DSL circuit, sharing the high-speed access among every computer in your home or office!

DSL Product Line:
Auracom currently offers SDSL, ADSL and IDSL services. However, DSL has many additional “flavors” as well. See DSL flavor descriptions below.

Upstream versus Downstream:
When discussing the different flavors of DSL it is important to understand the concepts of upstream and downstream in the context of the Internet. Downstream is like downloading. It means you are downloading information from the Internet to your computer. Examples of information traveling downstream are opening a Web page on your computer screen or opening e-mail messages from your inbox.

Upstream, on the other hand, means you are sending information from your computer to the Internet. Examples of information traveling upstream are sending e-mail messages, hosting a Web server and video conferencing. If you have ever tried to send e-mail with a large attachment, like pictures, large spreadsheets or electronic presentations, you understand how a slow upstream connection can really slow you down.

SDSL (Symmetrical Digital Subscriber Line):
SDSL is a symmetrical service, which means that information travels upstream and downstream at the same rate. It was designed for applications requiring high speeds in both directions. SDSL speeds begin at 192 Kbps and go as high as 1.1 Mbps. SDSL is well suited for business applications because of its symmetrical nature.

ADSL (Asymmetrical Digital Subscriber Line):
ADSL is an asymmetrical service, which means that information travels downstream at a different rate than it travels upstream. ADSL offers faster downstream (from the Internet) than upstream (sending to the Internet). Auracom offers two speeds: 768 kbps downstream by 384 kbps upstream, and 384 kbps downstream by 128 kbps upstream. Originally designed by telephone companies to provide video-on-demand to compete with the cable TV industry, ADSL was given new life with the advent of the Internet and the desire of residential customers to access the Internet with a fast downstream connection. ADSL is primarily used by residential power users who generally download information far more than they upload information.

IDSL is essentially used to provide DSL service to customers who do not qualify for SDSL or ADSL. IDSL is capable of reaching customers who are up to 36,000 feet away from the Central Office. IDSL operates at a symmetrical speed of 144 Kbps.

HDSL (High-bit rate Digital Subscriber Line):
HDSL was developed as a faster cousin to ISDN, and it enabled telephone companies to offer T-1 (1.544Mbps) speeds over regular copper phone wire without the use of repeaters. However, HDSL requires two pairs of wires, making it more expensive to provision than newer DSL flavors that operate on one copper pair. HDSL is the oldest and most heavily deployed version of DSL.
