Re: **Post all your BSNL Dataone Related Queries Here**
I never said you were wrong.. the link you gave does add up to what I said which is that the settings have really nothing to do with SNR. It keeps varying. It could be decieving as you might see a better SNR when you change a setting but that is only because SNR keeps varying. And every time you change a modulation setting on your modem, it has to resynchronise with te exchange leading to a different SNR value. Hence you see a different SNR when you change the modulation setting and very decievingly enough we unfortunately come to the conclusion that the setting is which changed the SNR.
One more thing that I should say is that, the ADSL we all use is capable of doing above 12Mbps. It has only been limited to 2Mbps and the SNR plays a very big role in it. If you need higher speeds the SNR has to reduced quite considerably comparing a 1or 2Mbps line. For example: on an 8Mbps line, the SNR should ideally be aroun 9~12dB. Like I mentioned before, higher SNR doesn't always mean good. If the SNR is increased too much by the ISP, you might see a slower connection but ofcourse a more stable one!!

on topic:
but ppl keeps experimenting!I knew that SNR stands for signal-to-noise ratio and if the value seems greater then i think shud settle for that option?as stand from the customer premise equipment.and what i think above values gave a wee-bit better performace may beand am not arguing with you
