ITU G.992.3/4 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2. It extends the capability of basic ADSL in data rates. The data rates can, in the best situation, be as high as 12 Mbit/s downstream and 3.5 Mbit/s upstream depending on line quality. The distance from the DSLAM to the customer's equipment is usually the most significant factor in line quality.
