Unanswered Question
Jan 14th, 2008

I try to install a Cisco 871 Router to connect to T-Home VDSL. But I do not get it to work. Now I read that Cisco does not support VDSL. Ist this still true??



I have this problem too.

Cisco support ADSL over pots, some model supports annex M. 871 has an ethernet interface. What is VDSL ?

Very High Data Rate Digital Subscriber Line.

Makes (theoratically) up to 53 MBit/s and you can have it here in Germany for Internet and TV over Internet.

Hi, I've looked around and it seems very few vendors have VDSL modems/router, zyxel and avm are exceptions.

Cisco has VDLS products but calls them LRE. It is not a consumer grade product and I don't think is interoperable with other vendors.

So to use your 871 on VDSL you will need to front-end it with a third-party VDSL modem/bridge.

Hope this helps, please rate post if it does!

871 doesn't support ANY DSL, because it only has ethernet interfaces. I'm assuming you're connecting a DSL modem to the WAN port of the router to make this work, which means the router isn't "doing VDSL".

Do you need to do PPPoE or something?
