What is ADSL2 broadband?

ADSL2 and ADSL2+ use the same cabling and exchange infrastructure as a regular ADSL connection. The software allows for greater amounts of data to be transmitted, which means that it can reach speeds of up to 3x regular ADSL – 24Mb download and 1Mb 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 high-speed connections:

• BE broadband
• O2 broadband
• BT broadband
• Virgin Media
• TalkTalk
• Sky
• Orange
• Eclipse

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 24 Mb downstream and 1Mb upstream, depending on the distance of the DSLAM (DSL Access Multiplexer) from the customer’s home.

Local conditions can vary, 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?
