cisco877W (ADSLoPOTS) connect to ADSLoISDN ?

Carsten Radke

Level 1

Is there a way to connect the cisco 877W (ADSLoPOTS) to an external dsl-modem ?

I've changed my telephoneline from analo to isdn.

Any help ?

If you have PPPoE, you configure that on the port that has a different vlan assigned to it:

http://www.cisco.com/en/US/products/hw/routers/ps380/products_configuration_example09186a0080094475.shtml

(note, you don;t need the vpdn group stuff in the example above).

But it is not said that you have PPPoE.

Hope this helps, please rate post if it does!

With an advanced services image, you should be able to create a vlan for the external modem.

If I understand right, I've to create a seperate VLAN to Fastethernet0, connect the DSL_Modem to Fastethernet0, make Fastethernet0 a member of my Diealergroup and thats it ?

Have you an example config for me ?

I've tried your response, but the router doesn't connect to internet.

The debug shows:

internet#sh debug

Dial on demand:

Hi,

you do not need vpdn-group.

Put the pppoe client under interface vlan10.
