Big Jump in Attainable Rate

I have noticed there is a big jump in attainable rate.

Before:

Downstream Upstream
Line Coding (Trellis) On On
SNR Margin (dB) 6.1 12.9
Attenuation (dB) 11.7 0.0
Output Power (dBm) 12.5 0.0
Attainable Rate (Kbps) 81523 27708
Rate (Kbps) 80000 20000

Now:

Downstream Upstream
Line Coding (Trellis) On On
SNR Margin (dB) 15.4 21.2
Attenuation (dB) 10.3 0.0
Output Power (dBm) 12.5 0.0
Attainable Rate (Kbps) 119523 37916
Rate (Kbps) 80000 20000

A crosstalker switched off?

Doubt a single crosstalker would see a 40meg fluctuation!

Not impossible though .... I have one close to me and the difference is 16-18 Mbps.

That's less than half the rate we're on about. Yeah it could be a couple of crosstalkers but unlikely they'd be off at the same time.

Latest after resync:

Downstream Upstream
Line Coding (Trellis) On On
SNR Margin (dB) 9.4 16.9
Attenuation (dB) 11.7 0.0
Output Power (dBm) 12.5 0.0
Attainable Rate (Kbps) 93323 30720
Rate (Kbps) 80000 20000

Dropped a fair bit although it is night time so more Radio interference.

Resync from 87 to this

Maximum data rate:
19999 / 120488

dsl:VDSL link Up: Down Rate=120488Kbps, Up Rate=19999Kbps, SNR Margin Down=0.00dB, SNR Margin Up=6.00dB

check vectoring status

Something odd happening with your attenuation, 11.7 to 10.3 to 11.7 ...
