Stats interpretation - please.


[link to this post]
 
Stats from HG612 below, it doesn't look like G.IMP is active. Engineer coming later this week since I am only about 250m from the AIO (new estate) and theoretically should be getting 80/20 (understand of course theres an overhead) but only getting around 46. BT though it was strange that upload was pretty much full speed but not the download.

Anyone spot anything unusual in the stats below if you have a sec ?
Thanks.

Are u sure of within 250m away from the cabinet? Your stats are look like you are approx 350m away!

Mine is much closer to the cabinet approx 250m below:

What estimate does www.dslchecker.bt.com give for the line?

I can see it's a Huawei cab but G.INP is not on.

Hi,

As mentioned 80/20 and yes, I can see G.INP isn't on as no Bearer info.

Sorry, that's not an estimate returned by the dslchecker.

I meant like this :
VDSL Range A (Clean) 80 69.6 20 20 63.1 Available -- -- --
VDSL Range B (Impacted) 80 55 20 17.8 39.8 Available -- -- --

It's based on the chap that pulled my line through and the raft of engineers I have spoken who did the AIO install, and all have said its its around 250 to 300m worst case.

At .3km BT expect around 76 less the overhead.

Just for info, I was previously getting around 28Mbps when the line was 1.3k to the old PCP, which meant it seemed to be performing better than normally expected. (normal estimates are around 23 for that distance)
