We have rolled a beta tool which will allow customers to toggle their Fusion lines between the standard download-priority (Annex A), and upload-priority (Annex M) modes.
You might choose to toggle upload-priority when you are about to start a really large upload, such as a huge HD video to YouTube or Vimeo, or when you are sending hundreds of high resolution photos from a photo shoot to a client. It would also be useful when making a large initial backup to a service like Crashplan or Mozy. Customers might turn it on before going to turning in for the night to cause an initial to complete more quickly.
But, because the upload-priority setting can slow your download speed by quite a lot, be sure to switch back to download-priority mode when you are finished with your uploading! Please also inform any other users of your connection that download speeds will be impaired while in this mode, so that they do not contact support about download performance.
For more details on Annex M, see: »wiki.sonic.net/wiki/Annex_M_FAQ
When you switch between the modes, your connection will be briefly interrupted while it re-connects with the new configuration.
A modem which supports Annex M and which is configured to automatically switch between Annex A and Annex M is required for this feature to work. Many modems support this by default, including the standard Sonic.net Fusion equipment.
While we are working on putting this into a permanent IVR, we will be opening it up for beta by way of a temporary number. Customers may call 707-583-7701
to experiment with the beta tool. In future, this number will stop working, being replaced by an IVR option under 611.
Annex M isn't something we support here by phone, it is a free "Labs" feature, which customers are welcome to use, but we cannot optimize or manage it. If you like Annex M, you can use it. If you prefer Annex A, you can toggle back. Please don't contact Sonic.net support about Labs features such as Annex A vs M, but please instead post to this forum for discussion.
