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.
Call for pricing. |

In
short, SDSL is mainly for business to have high speed access. It
requires more hardware, provides more bandwidth, thus is more
expensive. ADSL is for the home user. It piggybacks on your
existing phone line, does not provide as much bandwidth as SDSL, and
thus is more affordable. |
