Thread: What is SNR & Attenuation ?

I've seen in many post that SNR and Attenuation values determines whether there is telephone line problem or any other problem. But I really want to know what these two words mean and what is the difference between these two.

Any help ?

My modem details are

Are these SNR & Attenuation values normal ?

SNR

29dB. or above = Outstanding

Attenuation

20bB. and below = Outstanding
20dB-30dB. = Excellent

Please check.
