If both links are from the same provider, discuss using multilink PPP / PPPoE with them. Decent ISPs and decent routers will support that readily enough.
If you're talking about DSL links from different providers, that represents an entirely different and more complicated set of problems. To multihome between different providers, you'd need to obtain an AS # and a sufficiently large routable subnet that folks will carry a global BGP routing entry for it. That used to be a /20, but I think that's more like a /18 nowadays. (If that doesn't translate, check with APNIC or whoever your regional registrar is; they've got pricing here: http://www.apnic.net/services/become-a-member/how-much-does-it-cost )
