VDSL is a developing broadband communications technology, which allows users to upload and download data at extremely high speeds, over a Digital Subscriber Line. Speeds can be as high as 1.5 to 2.3 Mbps for upstream (sent) data, and 13 - 52 Mbps for downstream (received) data. VDSL's main limitation is the fact that it only works over relatively short distances (up to 4500 feet).

SDSL (Symmetric Digital Subscriber Line) - Description
SDSL is a type of broadband technology that allows for digital data to be sent at high speeds along already-existing copper telephone lines, while allowing for the transmission of analog (voice) data at the same time. SDSL connections are symmetric, meaning that they transfer both upstream (sent) and downstream (received) data at the same speed (usually about 3 Mbps).
