ADSL2+ / ADSL Plus

TU G.992.5 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2+ or ADSL2Plus.
Commercially it is notable for its maximum theoretical download speed of 24 Mbit/s.

ADSL2+ works the same way as a standard ADSL broadband service: it delivers a fast internet connection over your phone line. What's different is that ADSL2+ can extend the performance of standard broadband - much like a software upgrade can extend the performance of your computer's operating system.


How fast is ADSL 2+?

Speed depends on a number of factors; most importantly, how close you live to your local phone exchange or cabinet. Other things, like the capability of your computer and the quality of the wiring in your house will also have an impact. This is the case for any internet service provider that offers ADSL2+.

In theory, ADSL2+ can deliver maximum download speeds of up to 24Mbps and maximum upload speeds of up to 1.0Mbps. Like any standard ADSL broadband service, the "up to" speeds are the technology's maximum possible speeds and the actual speeds will vary for a number of reasons.
