Standard ADSL is only able to provide a service on lines with an attenuation no greater than about 75 dB. Category II performance and characteristics are not required for compliance with this Recommendation.

Put new text under old text. The second graph is of more importance since it is attenuation which is the governing factor for line speed because attenuation rate over distance can vary significantly between various copper lines due to their quality and other factors. This suggests an unstable line with repeated disconnects and the connection time of less than 30 minutes looks suspicious. However, ISP’s and modem producers use this technology and relevant information is not available.
Error correction is done using Reed-Solomon encoding and further protection can be used if Trellis encoding is used at both ends. Modulation is the overlaying of information or the signal onto an electronic or optical carrier waveform.

The word “will” is used only to designate events that take place under some defined set of circumstances. The gain obtainable above the noise floor can be anything from 0.
Thanks for all the replies.

I don’t mind ituu if that is going to be the best option but I just need my profile raising to get close to my router connection speed. An ADSL transmission unit can simultaneously convey all of the following: Thank you for your work so far, Van Tucky I have rebooted the router but it still shows as Also although my connection on the router is showing as kbps my throughput is k and my ip profile is k.
