Upstream VDSL?

Upstream Downstream
Current Rate (Kbps) 394 20540
Max Rate (Kbps) 476 26175
SNR Margin (dB) 6.3 7.5
Line Attenuation (dB) 66.7 25.9
Errors (Pkts) 0 0

Can anyone tell me how to get a lower upstream attenuation? openreach insist line is fine, but does drop now and then, and master socket with modern vdsl faceplate, is it due to upstream power back off? (UPBO) or cabinet finding it hard to hear the router? tried different routers so not that either.
(ECI Cabinet and 1Km Line from cabinet)

What modem?

If you can use DSLstats the graphs may show something.


At 1km the downstream is about right but as you know, Upstream is appalling.

Have just checked on a 3km line I have access to and they are seeing 3.1 down with around 1.4 up.

Probably a duff port in the cabinet. OP will need to get their ISP to get Openreach to out and test from the PCP. Hopefully they can do a lift and shift their and then

Dumb question, but are you still on FTTP as per your sig ?

If so this MUST be a remote profile issue.

If it�s now FTTC, then I�d suggest you have a duff VDSL modem.

If they were on FTTP then none of those stats would be relevant. There is an extra line on the sig that says "now on...".

But that might just have been a lower speeds profile the OP had requested moving to ?

And the stats might have been a software glitch - I dunno.

But attenuation, SNR, etc aren't relevant to FTTP. All figures would be 0 if displayed at all.

In addition, I seem to recollect that the Upstream Line Attenuation is not normally given on FTTC.

Certainly on my EE Brightbox 2, it is 0, while the Downstream LA is 13.4, on a Line Length of about 300 Metres.

Depends on the modem.

On an HG612 under basic stats there is nothing for upstream however in Telnet you can get:

Line attenuation (dB) . . . U0 . U1 . U2 . U3 . U4 . D1 . D2 . D3
30 Nov 2017 07:52:13 . . 4.3 22.5 33.9 N/A N/A 11.6 28.0 42.8

The extra dots just to align the columns.
