Hi everybody,
I have Cisco 1721 router with two Wic1-ADSL cards, I wanna setup internet connection over two 2048k adsl lines. However, I want to router automaticaly balance the total bandwith, in other words router should balance all incoming request on these two lines and if a problem occur at one of this connections, router should automatically forward requests to 2.nd ADSL line (may be called redundancy or something like that). If it is possible to make two sided balancing (incomig & outgoing ) it is more beneficial to us. 
I am new at routing, so you may advice other suitable technologies that correspond our need. 
My English is not very good, I tried to explaint in the best way. I really need such a solution, thank you.

here only ONE card is configured, i need to change this configuration to support 2.nd card with solutions that I mentioned above.
