Asymmetric DSL 2

Definition
Asymmetric DSL 2 (ADSL2)

"[e]xtends the capability of basic ADSL in data rates that range up to a minimum of 8 Mbps downstream and 800 Kbps upstream. Support of net data rates above 8 Mbps downstream and support of net data rates above 800 Kbps upstream are optional. ADSL2 utilizes the same bandwidth as ADSL but achieves higher throughput via data compression techniques."
