They are moving to Band Plan 998
OK, have telnetted in had a closer look and dug out the old stats - you are, indeed, correct. [edit] Oh, and I can see that this has already been discussed on the "Strange speed increase" thread - apologies for not keeping up
I now get
xdslcmd info --pbParams
xdslcmd: ADSL driver and PHY status
Status: Showtime
Retrain Reason: 0
Max: Upstream rate = 11817 Kbps, Downstream rate = 49388 Kbps

============================================================================
VDSL Band Status U0 U1 U2 U3 D1 D2 D3
Line Attenuation(dB): 6.5 33.2 48.3 N/A 16.2 40.3 61.4
Signal Attenuation(dB): 9.5 32.3 47.2 N/A 16.2 40.3 61.4
SNR Margin(dB): 8.0 8.1 8.1 N/A 10.3 10.4 0.0
TX Power(dBm): -4.4 -11.8 6.1 N/A 10.7 7.9 -128.0
It looks to have given up on D3 altogether given the 61.4dB attenuation so basically I'm just benefiting from the fact that the D2 tones now go from 1216 to 1973 compared to 1192-1627 previously. I remain slightly surprised that U/S attainable hasn't improved given that U2 should now come into play (albeit at 48dB attenuation)
It's a good move on my line - gives me back max sync and some overhead against crosstalk. Not much point me going for 80/20* but I'm happy at 40/10 compared with 3Mbs
-1 on ADSL.
*might have done if the U/S had improved even if the D/S didn't change much.
