However the fact which u have seen is however not untrue.... Ever used a download manager with a dial-up connection? Start a download... and it starts of with a speed of say 12kbps and then after a second or two reverts back to 4-5kbps..... now if u pause the download and restart after say a minute, u will get speeds of 35kbps or more for a few seconds..... but the speed will come down soon..... in lay man terms the "Unutilised bandwidth" gets "ACCULULATED"!!!!!!!!!! It wud be difficult to mention the entire technology behind this... better go for a networking course for CCNA then....

This artifact is side effect of TCP congestion control, at least NEW RENO/RENO the most deployed TCC exhibit this behavior of sawtooth, in lay man terms start at full capacity and when you hit the barrier get down too steeply /AIMD/.
IT HAS NOTHING TO DO WITH BANDWITH ACCUMULATION
Hence, in broadband, there is more idle-time, along with higher bandwidth... resulting in higher speeds for a longer time..... but try downloading a huge torrent, etc for a hour or so.... and check the download speed.... it is expected to be around the average...
[/b]
Idle time doesn't matter here since every subject's get their share of profiled queue usage.
Another factor is SWITCHING EXCHANGE... Main exchange proportionately divides bandwidth among the sub-exchanges..... so if u happen to live in a locality where there are fewer no. of BB users.... u get the addnl higher bandwidth..... hwever if u near a posh locality where there r many BB users, the bandwidth gets shared..... resulting i lesser speeds......

1:50 and 1:20 ratio of
ADSL for general usage is something whose occurrence is rarest of rare in practical deployment.
So the bottom line is.... ADSL modems cant be uncapped..... and it also depends upon the are u live in....
[/b]
True it can't be capped or uncapped at CPE and it doesn't depends on where do you live at.
ADSL CPE just can't be used to capped or uncapped unless DSLAM or BRAS is b0rked.
PERIOD

he connects at 792 kbps on his 900 plan!

Could you please post some snapshot of network statistics, it seems the sync rate between CPE and exchange DSLAM is totally misinterpreted here.
Give us some more details.
