Hi everyone,
I wanted to configure a Cisco 2901 for a ADSL connection but without success. I didn´t event got a link on the atm interface.
I tried the same connection with my a Cisco 870 and there I´ve got a connection. So I guess my DSL link is ok.
Can someone help me please to find my mistake?
Best regards
Robert

Hello
Try to configure dsl operating-mode auto (or choose the appropriate ADSL mode if you're sure) under the controller VDSL0/2/0 configuration sub-mode.
You may also want to configure the encapsulation to be used under the pvc1/32 configuration sub-mode: encapsulation aal5mux ppp dialer if using multiplexing. The default is to use AAL5+LLC/SNAP. Also please make sure that your VPI/VCI is correct.
Can you please provide the output of the following commands:
show controllers VDSL 0/2/0
show controllers atm 0/2/0
show atm interface atm 0/2/0
show atm pvc interface atm 0/2/0
show atm pvc 1/32
Best regards,
Martin

Hi Martin,
The idea with the dsl mode showed me the right way. My controller is a EHWIC-VA-DSL-A but what I need is an EHWIC-VA-DSL-B because I need EHWIC over ISDN.
Now I have to change the module. Thank you for you answer.
best regards,
Robert
