India Broadband

I have two Tataindicom connection one is 512 Kbps and 256 Kbps with modem Telenet Tndsl 2120 and Electric Co. ADSL modem/router.

I have tested result after interchanging modem:

SNR Margin (Higher margins are good) :->
Line attentuation (High line attentuation is bad) :->

Line of 512 result:
Telenet modem: 30.7 down / 9 up
Billion Modem: 19.2 down / 9 up

Line of 256 Result:
Telenet modem : 9.9 down / 9 up
Billion Modem: 6.5 down / 9 up

As my personnel experience Billion Modem as lower performance.

Now my question is :
1. Which modem is better between Telenet Tndsl 2120 & Electric Co. ADSL modem/router ?
2. How can I improve my SNR Margin?

Thanks for any idea!

I think you have specified only SNR ratings. What about Line Attenuation ratings ?

1. Which modem is better between Telenet Tndsl 2120 & Electric Co. ADSL modem/router ?
Higher the value of SNR, the better it would be. And attenuation would be higher if you are away from Exchange. So from SNR ratings, Telenet Tndsl 2120 is good.

2. How can I improve my SNR Margin?
SNR rating depends on many factors like line quality, number of bridge taps, lifetime of line, improper earthing, improper joints and others. So from our end we cant do anything. we can approach service provider, he might be able to help but am not sure.
