DSL
(Digital Subscriber Line) technology supplies the necessary
bandwidth for numerous applications, including high-speed access to
the Internet, dedicated Internet connectivity, and
videoconferencing.
This digital broadband line directly connects your premises to the
Internet, via the existing copper telephone lines.
There are many varieties of DSL technology (generally described with
the term "xDSL"). DSL.net provides the optimal business-to-business
solution, SDSL.
SDSL (Symmetric Digital Subscriber Line) —This technology
provides the same bandwidth in both directions, upstream and
downstream. That means whether you're uploading or downloading
information, you have the same high-quality performance. SDSL
provides transmission speeds within a T1/E1 range, of up to 1.5 Mbps
at a maximum range of 12,000 to 18,000 feet from a central office,
over a single-pair copper wire. This option is ideal for small- and
medium-sized businesses that have an equal need to download and
upload data over the Internet.
For a complete list of industry terms, view our glossary. Other
varieties of digital subscriber lines include:
ADSL (Asymmetric Digital Subscriber Line) — This technology
reports a downstream speed, but its upstream speed is a fraction of
the downstream. Primarily used in residential applications and many
providers do not guarantee its bandwidth levels.
RADSL (Rate Adaptive Digital Subscriber Line) —This
technology automatically adjusts the access speed based upon the
condition of the line.
IDSL (ISDN Digital Subscriber Line) —This technology is
symmetrical, similar to SDSL, but operates at slower speeds and
longer distances.
HDSL (High-Data-Rate Digital Subscriber Line) —This
technology is symmetrical, but is mainly deployed for PBX over a T-1
line.
VDSL (Very-High-Rate Digital Subscriber Line) —This is a
high-speed technology, but has a very limited range.
