Draytek will not give you any info about the chip-pest but it will go up to 90mb
For your info the one i got last year is got ADI and works very well with infineon adsl connection (TT LLU)
It synchronise same as supplied TT dsl 2680 modem
I add a billion 7800 untweaked and will synchronise 1-1,5mb less
Also same with asus dsl n55u 1-1,5mb less than the 2850 in a line of 2.400m
Never tried with VDSL because i am direct to exchange
You can not tweak the snr but they have 9 firmwares for compability with different dslams and you can update it or change modem code very easy
I still using it daily because its features are really so helpful for me and for my 2 connections VM & TT adsl it handles
really well even personal i am not getting more than 90mb (usually around 85mb) out of 100mb VM connection
Hopefully they will update it sometime later
If you have 2 connections i do recommend it..this is from the best out there for this job
If you want it just for speed over 100mb don't go for it
by the way any one knows what is the chippest of the dsl 2680?
Thanks
PS for speed up to 800mb this is the one draytek 2130n
