What is 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.
