What's up with the magical 10 day window?

My bet is that some time within the first 10 days of your service being active, your connection gets profiled (possibly by a human, although more likely by an automated system) which determines whether or not you're getting ideal speeds.

The fastest link speed between the modem and the DSLAM may not always result in the fastest overall connection speed, especially in less then ideal line conditions. There is little point in communicating at 900Kb with 50% packet loss vs 850Kb at 1% packet loss.

One explanation that I've heard is that during the first 10 days some DSL providers do some background testing and "tweaking" of the connection performance between your DSL modem and the DSLAM. This should allow the best performance over your line.

As I recall, the DSLAM and DSL modem are adapting themselves to the unique characteristics of your phone line. By leaving the modem on, this enables this process to run to completion. I suspect that an occasional interruption wouldn't really make any difference just so long as the modem is on almost all of that time.

Seemed to make sense to me.....

Welcome to SBC Internet Services...

The "Ramp Up" period has been explained a few different ways.

One way that almost makes sense is this: The speed starts at some low, safe speed. It is then increased each night by a certain increment. When errors start to appear, the speed is then decremented, establishing the 'best' speed for your particular line.

The line testing takes place in the wee hours of the morn and rather than tell customers their modem must be on during the period of 10pm to 8am (for example) it is much easier (and more likely to produce compliance) to leave the modem on all the time.

P.S., most people leave their modem on all the time regardless of whether 10 days have passed or not.

Yes,

It's sort of like one of those psychological mind games. I currently have Comcast and don't even remember the last time I turned off or disconnected my modem. I would have never even contemplated turning off my DSL modem either, at least not until I saw this sticker. Now, because I'm told that turning it off is a no no, I'm coming up with all these reasons why I might need to do so...:) oh well.

Sounds like the warning label found on an iron recently. "Do not iron clothes while wearing"

Note that you do NOT necessarily need to have your PC on or connected. Just leave the DSL modem on the first 10 days so they can determine optimum speed if your line is not good enough for full speed.
