SDSL (Symmetric Digital Subscriber Line) – Description

Written By: Jeremy Maddock

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).
