How to configure ADSL connection on WIC-1SHDSL Interface Card


I have a Cisco 1841 router and one WIC-1SHDSL Card. We have ADSL internet connection though ISP but i am unable to connect using this card. What i believe is that this WIC does not supports ADSL/ADSL2/ADSL2+ connection types. Below is my configuration.


controller DSL 0/0/0

line-mode 2-wire line-zero

line-rate auto


interface FastEthernet 0/0

ip add - Public IP

ip add 255.255.2550 secondary

ip nat inside

no shutdown


interface ATM0/0/0

no ip address

no atm ilmi-keepalivies


interface ATM0/0/0.1 point-to-point

ip add

ip nat outside

pvc 8/80

     encapsulation aal5snap


ip nat inside source list 1 interface FastEthernet 0/0 overload


ip route


access-list 1 permit


My ISP said that your WIC is not support ADSL/ADSL2/ADSL2+

Hello Shareef,

your guess is correct


>>>What i believe is that this WIC does not supports ADSL/ADSL2/ADSL2+ 


SHDSL is a different type of DSL with symmetric upstream/downstream rates and it can not be used over an ADSL* line as you have tested.


Hope to help
