Re: Serial interface dont appears in my config

Different IOS releases support different hardware modules. Your version of IOS might not support the WIC-1T, in which case you'll need to get a version that does (there's an online hardware-software compatibility matrix that can help here).

Run 'show version' to confirm whether or not the router can see the WIC card. Reinserting the card coudn't hurt either.
