ITU G.992.3/4

ITU G.992.3/4

ITU G.992.3 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2. It optionally extends the capability of basic ADSL in data rates to 12 Mbit/s downstream and 3.5 Mbit/s upstream (with a mandatory capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 Kbit/s upstream). Actual speeds may reduce depending on line quality - usually the most significant factor in line quality is the distance from the DSLAM to the customer's equipment.

ITU G.992.4 is a standard for splitterless ADSL2 with data rate limited to 1.536 MB/s downstream and 512 kbit/s upstream.
