Question regarding IP profile

(btw anyone who's read any of my posts before, turns out the problems I've been having for years were on the phoneline outside my house, but all this time broadband engineers have ignored it because 'only the telephone engineers deal with the actual cables'....)

 

 

My question is regarding IP profiles today

 


 Download speedachieved during the test was - 425 Kbps
 For your connection, the acceptable range of speeds is 50-500 Kbps.
 Additional Information:
 Your DSL Connection Rate :1120 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 500 Kbps

 

My router has been synced for a few days now at around 1000kbs, but my ip profile is stuck aroudn 500kbs

 

How do teh DSL sync and IP profile correlate to eachother - or do they at all?

 

I've always assumed that the DSL rate is what speed my connection is aiming for, and will either be caught up by the IP profile when the exchange has finished its calculations or will be decreased by the phone exchange until the IP profile and DSL rate are the same?

 

Cheers for the info.

Re: Question regarding IP profile

Basically the IP profile is set according to your sync speed and there are certain values for different parametres, this table shows the figures

So your profile should be 750kbps.  Your profile will take up to 5 and usually by 3 days to catch up with your sync speed say if it falls out of the range, so if your connection went up to 1152 then it will take around 3 days to increase.  The bigger jump the profile has to make the quicker it will update whereas the smaller the increase the longer it will take.  And not symetrically the profile will take 'up to' 75 minutes to reduce, but ususally much quicker.

 

On ADSL2+ lines, they use this technology but a new profiling system is being rolled out across the network and your profile is always 88.2% of your sync speed and updates immediatley both increase and decreasing figures.
