jazztel_teamJazztel is promoting their doubled upload with YouTube videos, the kind of application that will put the 2.5 megabit upload speed to good use. They unveiled a dedicated website at a large press event. annex_m_jazztelAnnex M has been in the ADSL2+ standard for years, but the early equipment simply didn't support it. Only a handful of ISPs are using Annex M, although most current chips claim to support the speeds. It's achieved by using a little more spectrum for upstream and a little less for downstream.

Internode in Australia is a pioneer in Annex M, and reports that 53% of customers are getting sync speeds of 1.8 meg or better.
  • 10.5% achieve an upload synch speed of higher than 2.4 Mbps
  • 24.7% achieve an upload synch speed of between 2.1 Mbps and 2.4 Mbps
  • 18.5% achieve an upload synch speed of between 1.8 Mbps and 2.1 Mbps
  • 40.4% achieve an upload synch speed of between 1.0 Mbps and 1.8 Mbps
  • 6.0% achieve an upload synch speed of less than 1.0 Mbps
