Newbie question about 1721 router with 2 WIC-2T

I need to connect 2 leased lines (2-wire each) from 2 different telcos to my office. The interfaces are both V.35

Can I use one Cisco 1721 router with one WIC-2T for the above configuration? Can one WIC-2T connect 2 differnt leased lines at the same time? Can the 1721 route data from 2 sources to/from the inbuilt Ether NIC?

I am on limited budget and don't know much about Cisco gears.

Thanks, ZP
