China Telecom (CHA), one of the main communications service operators in China, is testing its ADSL2+ based Super ADSL service and is expecting to formally launch it soon.

At present, the Super ADSL is undergoing an internal test and it is still not known when it can be put into commercial use.

The data rates can be as high as 24 Mbit/s downstream and 1 Mbit/s upstream depending on the distance from the Digital Subscriber Line Access Multiplexer to the customer's home. But most telecom companies in major cities like Beijing, Shanghai, Nanjing and Guangzhou say they have no plans to launch ADSL2+ in the near future.

The International Telecommunications Union published two ADSL standards, namely G.992.3 and G.992.4 (ADSL2) in July 2002. In March 2003, it made another standard based on the first generation of ADSL called G.992.5, which is also known as ADSL2+.
