Seen in the test lab: 46Mbps/4.8Mbps pair bonded ADSL2+


This week we have demonstrated ADSL2+ connection speeds of 46Mbps downstream and 4.8Mbps upstream. Our network design team achieved this speed in the lab environment, on a short copper loop.

Because of longer loops and interference, this is not a speed that we will see in the real world, but it is very exciting to see the full potential of ADSL2+/Annex M.

Today we have staff with real world loops running at over 30Mbps, so that is a more realistic goal.

Two pairs of telephone wire were used in the test to deliver a bonded (double pair or four wire) ADSL2+ link, with Annex M (double upstream) capability turned on. Actual FTP transfer speeds were demonstrated at over 42Mbps upstream and 4.5Mbps outbound after overhead.

We are working on the wrap-up of product design and pricing for our new pair bonded Fusion products, and we plan to announce the details shortly.

Sonic.net Fusion Broadband continues to bring customers innovation in Internet access.

For folks interested in some of the technical details of the new solutions we are deploying, here are some links:

Our current deployment can support bonding of up to two pairs of ADSL2+, and up to eight pairs using EFM. You can do the math. =)
