Thread: Confusion About Line Attenuation

Hello Folks
Good Evening

I have a bit Confusion At this Moment
Why i have very High Line Attenuation Downstream Rate But Upstream is Good

I am Not facing any hissing sound in phone line

Please clear me on this

It is quite common. Happens with most users. Not of much concern.

so i have to worry about it?

no need to worry.even with a downstream attn of 45-50 you can easily get 2mbps.my downstream attn is 43 & i get usual speed.

@whitestar_999 I am Not Worry About Speed ....

few months ago i was facing dsl link up and down every few mins
i hope i will Not face again with this line

attn mainly affects speed while SNR values affect connectivity.usually low SNR values <10 for connections 8mbps or below results in DSL link problem.

Yep, it is SNR that causes disconnection.

Theoretical Speed/distance calculator. ( EXCEL required)
Enter the value and click.

Since GDMT is not working in BSNL, try ADSL2 mode to reduce the sync rate.

Slight improvement in SNR expected. 3 dB rise will be significant for a stable connection.

Feedback with SNR attn values.

Beginners like me, usually follow this table: as a general guide.

Same happens to me and I was bothering as well.
