ADSL2 and ADSL2+ use the same cabling and exchange infrastructure as a regular ADSL connection. However, the software that makes the technology possible allows for greater amounts of data to be transmitted, which means that it can reach speeds of up to 3x regular ADSL – 24Mbps download and 1Mbps upload.
As with ADSL connections, the distance of your house from the telephone exchange and the quality of the copper wiring can have a significant effect on the speeds you are able to get.
Nearly all main ISPs now offer an high-speed ADSL2 service alongside even faster fibre broadband connections:

ADSL2 broadband in technical terms
ADSL2 is also known as ITU G.992.3, which is an ITU (International Telecommunication Union) standard. ADSL2 and ADSL2+ extend the capability of regular ADSL by doubling the number of downstream bits. This can lead to connection speeds of up to 24MbPS downstream and 1MbPS upstream, depending on the distance of the DSLAM (DSL Access Multiplexer) from the customer’s home.
Speed is still affected by distance from the exchange, especially beyond 2km. But the closer you are to the DSLAM the higher your Mbps will be. A DSLAM is a network device that enables telephone lines to have faster connections to the internet. It collects digital signals from its multiple modem ports and combines them into one signal through a process called “multiplexing”.
In this way, the DSLAM allows telephone companies and ISPs to provide fast copper wire internet connection technology (DSL) with the fastest backbone network technology (ATM, asynchronous transfer mode).
How do I get ADSL2 broadband?
Luckily both ADSL2 and ADSL2+ can run on regular ADSL phone lines, but you may need to upgrade or purchase a new router to get the most out of your new connection. To be sure, always consult your provider.
Although nearly all main ISPs offer ADSL2 broadband, these services are dependent on location. Use our uSwitch broadband postcode checker to see what is available in your area. Prices, packages and availability may change, so be sure to double check with the provider.
Who is ADSL2 broadband for?
ADSL2 is great for online gamers, as well as those who want to enjoy music and movie streaming, and it's just as useful for video conferencing and seamlessly listening to digital radio over the internet. People who use Peer-2-Peer software (for downloading media) will benefit from the faster speeds that this connection offers.

ADSL2 vs fibre broadband
Fibre broadband offers maximum speeds that dwarf those you can expect with ADSL2. It's also even more reliable, with availability spreading to new parts of the country every day.
