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.
ITU G.992.5 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2+. This extends the capability of basic ADSL by doubling the number of downstream bits. The data rates can be as high as 24 Mbit/s downstream and 1 Mbit/s upstream depending on the distance from the DSLAM to the customer's home.
ADSL2+ is a hot topic because it is capable of doubling the transmission speed of typical ADSL connections from 1.1 MHz to 2.2 MHz. This doubles downstream data rates to over 20 Mbit/s, but these data speed rates will only be attainable on loops shorter than 8,000 feet (2.4 kilometres).
Znaci, mnogo je brze, 2 ide do 12 Mbit/s a 2+ i preko 20 Mbit/s ali mnogo zavisi od udaljenosti korisnika od centrale, zato sam i rekao da ce po gradovima to dobiti pre urbanih sredina.
