ADSL

ADSL (Asymmetric Digital Subscriber Line) is a transmission technology that dramatically accelerates data transmission via a standard twisted pair copper cable.

With this “Asymmetric” version of DSL in which data is transferred downstream at rates of roughly speaking up to 10 Mbit/s and upstream up to 800 Kbit/s. The unequal data rates for downstream and upstream data transfers explain term “Asymmetric.”

With ADSL2 the data rate downstream is as high as 16 Mbit/s, for ADSL2+ up to 24 Mbit/s and with VDSL, up to 52 Mbit/s may be realized.
