Does it work with German T-Com VDSL?
Yes. You need to disable auto-neg, set 1Gb fixed and create an interface with VLAN ID 7.
The "/interface dsl" menu is gone in 6.40.5 and 6.41rc56 on a CCR1009.
Can someone confirm this?
Transfer rates are rather pour. On a 100/40 VDSL I get:
ZyXEL VMG1312-B30A: 13ms, 102/41 Mb/s
Vigor 130: 19ms, 90/31 Mb/s
Proscend 180-T (Telco): 12ms, 71/24 Mb/s
Transfer rates did not get better after 24 hours.
I rather stick with my ZyXEL. It's what Deutsche Telekom recommends. Also it's more stable than Vigor/Proscend, e.g. I can see drops in the transfer rate on the others. Even that the ZyXEL has only 100Mb/s Ethernet, it gives the best results.
