My question is the noise margin and line attenuation right for my line. I live in the middle of no where pretty much and The line length is about 3.5 KM to the exchange.
Hope someone can help. All I want to really check is that I am getting the maximum possible speed my line can handle.
Thank you and Happy New Year 🙂
Can I ask what exactly loop loss is please.
Also can the margin be reset or changed so the speed goes faster.
It's your line attenuation .... its distance erosion from the exchange ... it's length.
I could give you the "purist" view, that at 36.5 db loop loss, you should have around IP 6.5M at target margin with excellent bitloading and running fastpath.
What that means is everything is perfect .... and rarely happens with line adaptive DSL.
So yours is on interleave, normal for some line errors, it's at 9db margin, so you lose a little more linespeed.
And if bitloading is average as well .... it all adds up .... BUT
What you can do, and I noticed you had a shortish runtime which meant you reset the router in darkness ....
Is do ONE reset in daylight hours tomorrow between 9 and 12, and your sync speed may improve, and then wait for the IP profile to come up to it .... that takes 72 hours.
Try that first .... see what happens, if you want to get the margin down to 6db, read about noise margins and line noise .... and how to get rid of it.
See what tomorrow brings .... 😉
I shall do that tommorrow and see what happens. you say I should have an IP profile of 6.5. My IP Profile according to the BT Speedtester is around 3.0 MB.
your profile is determined by your connection speed which stats show to be 3744 hence profile is only 3mb. if you can get noise margin down and connection speed up then your profile will increase
