[SIZE=10pt]Line Attenuation[/SIZE]
[SIZE=10pt]Line attention is in relation to the "loop loss" on your line. The further you are away from the exchange the higher your attenuation figure will be as the signal loss increases. The lower your attenuation figure the more chance you have of getting the faster speeds.[/SIZE]
[SIZE=10pt]SNR (Signal to
Noise Ratio)[/SIZE]
[SIZE=10pt]The SNR margin can only be measured from your own property and therefore to be measured correctly may need an engineer visit to check this figure from the ISP test socket behind your master phone socket. Your SNR Margin can fluctuate on a day to day basis and may vary depending upon local equipment, conditions and interference. An upgrade in speed often causes the SNR to decrease by up to 5 dB. The higher your SNR figure then the better your line quality and therefore a higher chance of getting faster speeds. It is very important to note that SNR plays much more importance in maxdsl[/SIZE] than it did on the traditional
ADSL product.
