What's Your SNR Ratio and Attenuation Rates? (BSNL Broadband)

[haija]

this is my office infowhat about this?Item Downstream Upstream Unit SNR Margin 33.0db 4.0db dB Line Attenuation 16.5db 13.0db dB

 

[somenormalguy]

SNR (Downstream) 31.65 dB SNR (Upstream) 23.5 dB Line Attentuation(Downstream) 22.5 dB Line Attentuation(Upstream) 6.5 dB

I have tested around 5 different modems from both MTNL/BSNL over the last month and each modem had different SNR value to show. The lowest was 26db down while the highest was 45db down. I don't think you can interpret your line strength with SNR values since different modems show different values of the same line. Just a FYI.

Look for 'Remote SNR Margin' if present in your Modem UI. It'll remain const. for all/most modems.

What you all are posting here is 'Local SNR Margin' which is = Remote SNR + Modem corrected/boosted SNR. It'll always vary from modem to modem. The same goes for attenuation.

Remote SNR => SNR before entering modem
Local SNR => SNR after processing in modem

SNR Margin (dB): 25.2(Down) 27.9(Up)Attenuation (dB): 39.0(Down) 21.0(Up)Any suggestions, quiet unusual when compared to others. Speeds are OK. i get 3 to 3.2 Mbps in the 4Mbps plan

Please upload a screen shot and give the link here.
or give an example of a commercial modem/router.

Downstream UpstreamSNR Margin (dB): 34.1 22.5 Attenuation (dB): 27.5 10.6 are these any good ???

Downstream Upstream
SNR Margin (dB): 34.1 22.5
Attenuation (dB): 27.5 10.6


are these any good ???

Your SNR is good enough but Attenuation looks a bit high, still looks like a 10-15 mbps capable line.

SNR Margin (dB): 34.3 28.6
Attenuation (dB): 19.5 9.4

These are mine & most of time my attainable rate ranges from 12,000 kbps to 20,000 kbps depending upon time !

Downstream UpstreamSNR Margin (dB): 33.0 18.1 Attenuation (dB): 6.0 3.1 And i'm having a 500 combo plan with MYWAY iptv

 

[geek]

just checked, my attainable rate was somewhere around 18.5k Kbit/s

Yep........good line quality, attenuation a bit over in downstream is not affecting much in ur case probably becoz ur SNR is gud enough !
