I wasn't aware Germany had 110/42.
Well, the thing is that it's not actually advertised as 110 Mbps. Both 1&1 and Telekom (Deutsche Telekom) advertise their speeds as up to 100/40 Mbps, but it appears that the DSLAM and modems when using 17a G.Vector seem to be able to acheive sync rate of up to 109344/41999 Kbps (DSLAM says 42000 is max. upstream rate, but I have not seen any modems at that exact figure). Perhaps the 100/40 Mbps refers to maximal throughput, but I somehow doubt it.
A guy who calls himself wunsel on the blogdoch blog did a "shootout" with various Fritz!Box VDSL modems which can be seen
here. It shows both the 7412 and 7490 hitting about as a high as they can go.
That's still a very long way from
Vectored 17a would have almost doubled data rates over standard 17a
I totally agree that would be true, and this was an oversight of mine when I initially wrote that out.
Most telcos who sell Vectored VDSL2 17a have 100Mb downstream.
Perhaps for practicality it would make sense just to say 100 Mbps downstream since the amount of devices capable of syncing at such speeds may be limited.
Either way, I think this should have all been it's own topic.
