Evo i objašnjenje za SNR i line Att ;
Have you ever heard about line attenuation? Leaving out some of the technical jargon, the line
attenuation figure describes the distance between you and the exchange of the ADSL provider. It is expressed in dBs and you can check this number on your ADSL statistics of your home / corporate router (
show dsl interface atm(something) for Cisco). In short, the lower this number is, the better:
20dB and below is outstanding
20dB – 30dB is excellent
30dB – 40dB is very good
40dB – 50db is OK
50dB and above is bad
Signal-to-noise ratio (SNR) is another figure you can check in the ADSL stats of your home / corporate router (
show dsl interface atm(something) for Cisco). This number is also expressed in dBs and describes the relation between your speaking strength (signal) and the street’s noise strength (noise). The higher this number is, the better, as your speaking voice outperforms the noise.
10dB and below is bad
11db – 20dB is OK
20dB – 28dB is excellent
29dB and above is outstanding
