Kirdog:sbiddle:Kirdog: Is it any way to lower noise margin of my connection?
My response to that is to ask you why you want to do this, and whether you actually know that the noise margin is?
A 26 - 28dB connection while delivering OK performance isn't by any means a brilliant connection.
Gain more speed, and more upload, every KB/sec of upload speed is important for me.
I don't know actual physics of the Noise Margin (anyway i have read wiki and some other resources.), but i know that:
* 6 db is a standard(default), provides high speed and normal stability. Everything lower is not good.
* 12 db more stable connection, and lower speed. But seems it is useless setting in some scenarios.
Incorrect.
12 db is the standard in NZ on all Chorus gear whether it be an ISAM, DSLAM or ASAM.
Most ULL providers have opted for 6 db or 9 db because they believe they can get away with it. The compromise is that they are are more likely to suffer issues from noise or crosstalk which is becoming a growing issue in some MPFs with growing VDSL2 uptake.
Chorus could easily reduce their noise margin but clearly have the stats to show they believe it's the best noise margin to be running and don't like going down the path many ULL providers are having to with individual profiles for multiple connections.
