From the looks of it my Sync Actual is third from the bottom of VDSL2 users on MyDslStats
that's why your attenuation is the 1st most important part of Modem stats.

 

[Chrysalis]

whats your username so I Can view?

[Chrysalis]

found it nstar

[NewtronStar]

found it nstar

Have noticed that some users attenuation dB is displayed as 0.0 your goodself included, not sure if this is intentional or the modem is unable to send the information to the stats program due to old firmware

[Chrysalis]

the zyxel doesnt display an overall attenuation thats why.

[NewtronStar]

the zyxel doesnt display an overall attenuation thats why.

Thank you Chry that clears that up

It does in here

[Chrysalis]

kitz notice how close your signal attenuation is to your line attenuation on D1.  I think thats due to lack of power cutback.

Here is mine (and also note my overall lower attenuation yet lower sync than you).

BE if you wondoering how this is shown its 'xdslctl info --webstats'

[kitz]

BE if you wondoering how this is shown its 'xdslctl info --webstats'

Just to add a bit further because I think BE uses the adsl info prefix for the Zyxel.

adsl info --webstats also works.

[roseway]

The --webstats option doesn't seem to exist on the Billion 8800NL.

same again with MK3 in and 72mbit cap removed.

kitz notice how close your signal attenuation is to your line attenuation on D1.  I think thats due to lack of power cutback.

Ive noticed before that your D1 bit loading shows a different shape than mine, and evidence of some form of shaping either through PBO / PSD Masks.
Out of interest is your cab a fair distance from the exchange?  The further away the cab from the exchange, then the more likely any of those VDSL lines will impact on neighbouring adsl lines, so it makes sense that as the cab distance from the exchange increases, then the more those vdsl lines will have to be shaped.
Yet on adsl its the short 'E' side lines that have PBO applied the most.  VDSL PSD masks not only have to consider distance from the cab, but also the exchange distance and have to be factored accordingly.   

btw iirc you asked in another thread what the difference between line and signal attenuation was.  I'd already pre-empted that question and put a link in the post previous,  which explained the difference between the 2...  but in summary yep because of the difference in which the way the 2 are measured, that could explain why you see a difference between the 2 in your D1 band.. which is where most of the PSD masks are applied.

yep is about3.7km, even tho I am 5 mins drive from the city centre, the local exchange here was removed in the 1980s, which has led to horrific E side lengths.

How to tell how many metres away from the street cabinet to my property?

[Chrysalis]

my guess is about 200-250.
