Kelsey and Tim have released a new tool in the unsupported "Labs" section of our Member Tools which allows Fusion Broadband+Phone customers to tweak their line settings for upload versus download priority (Annex M versus Annex A), and also to see line performance and traffic graphs.

To reach the Labs features, visit our home page at http://sonic.net/ and select Member Tools in the upper right. Authenticate with your Sonic username and password and then see the Labs area toward the lower portion of the menu. (If you've misplaced your Sonic password, you can recover by following the prompts on the Member Tools login screen.)

To make it easier right now, here's a short-cut direct to the tool:
https://members.sonic.net/labs/fusion-line-profile/

These are the same settings which Fusion customers have had access to for some time now by dialing 611, option 2.

From a support perspective, our goal is to deliver a stable and reliable standard Fusion connection, so please do not contact technical support about fiddling with your connection profile. You are welcome to play with the setting and compare speeds using the charts, but we can't "fix" a connection where upload priority doesn't perform in whatever way you might hope. Sorry! Labs features are free experimental add-ins to your service, and are offered for your use without the full weight of our technical support commitment. Thank you for your understanding.

As a general guideline, upload priority (Annex M) is generally best for shorter loops, and can as much as double the upload speed. It's just not quite fair, but a member who obtains 20Mbps/1Mbps using the standard configuration might see 18Mbps/2Mbps when upload priority is turned on. But in some cases it will yield little or no gains in upload speed, while download always decreases, sometimes to a great degree. On a longer loop where a member is obtaining 8Mbps/1Mbps, turning on upload priority could yield a result like 4Mbps/1mbps. It's a mixed bag.

It would be interesting if you experiment with it to see your before & after sync speeds down and up, as show in the new Line Profile tool or in the modem's interface at http://gateway.sonic.net/. Post them in reply here if you do this testing! If you want to get real fancy, you could even post the performance charts. Note that the charts only update every five minutes, and show a 24 hour span, so you'll have to leave a setting in place a while and reload the charts after a bit to see the change.

Have fun!

It would be great if the D/L didn't drop so much, plus the Echo is bit high now.

Odd that both say Annex A.

Yes that is odd. I didn't even notice that. Switched back and forth a few times and it always shows Annex A.

Way cool and well done! Thanks, Dane, Kelsey, and Tim!

Your service does not currently support a Fusion profile configuration.


I'm quite a ways from the CO so this doesn't surprise me.

I believe this error comes up if you don't have Fusion Broadband+Phone, as all the APIs are tied to the telephone number.

This is great!

It would be very helpful for customers with modems that are behind a router - as they usually cannot access the modem menu/statistics. With this tool they can see, over time, their upstream/downstream sync rate.

If you could add the SNR numbers, it might help some customers squeeze more speed out of their line :) eg. anyone with SNR consistently more than 10 dB probably can raise their speed cap safely.

Perhaps a 48 hour graph could better identify issues related to particular times of the day ie. you see a dip every dinner time, etc.

The traffic graph is also useful for those with routers that lack a built-in bandwidth monitor.
