although they should both be supported.
From you post it looks as if you are running 12.4.23 IOS version.
these modules are supported in the T train. I guess the min required for adsl card is 12.4.6t
Suggest you upgrade the IOS to the T train as suggested by Paolo.
No, it is not. Please read about 12.4T.
You need a T version of IOS to support these cards. You currently have a mainline version of IOS.
