I did light-heartedly say "about 0.5"!

I stand by my statement, backed by Kitz:
It is also worth pointing out that attenuation is calculated differently for adsl and adsl2+, and its not unusual to see an increase of 3-4 db when moving from adsl1 to adsl2+.
He predicts:
Downstream Attenuation 53 dB

dslMAX 4128 kbps


adsl2+ (21CN) 4320 kbps
vs.
Downstream Attenuation 56 dB

dslMAX 3424 kbps

adsl2+ (21CN) 3712 kbps
Q.E.D.

In reply to a post by MrSaffron:
What should happen is that the modem only use ADSL2 mode if this was to happen
But it doesn't! We have often seen users on long lines being auto modulated on ADSL2+ and we have advised that switching to ADSL2 only would prob gain them Sync.

That would be because Kitz site has just one curve for the speeds, and thus is reading them off, I do the same. Can't do much else as there is no firm data to allow people to do otherwise.

Agreed! That's the only sensible way to predict.

Even if you took the Max curves you would have ADSL = 4.6 Meg @ 53 dB attn. to ADSL2+ = 4.0 Meg @ 56 dB.

He predicts:




He is a 'she' and said ADSL2+ calc is not especially accurate (few are). I tend to look around at many and take the average of the lower half results as a prediction, then anything else is a bonus.

Good job because you'd be straight back off to Virgin if you did.
