[RT] two modems on network

["Lee Morris" <LMorris@xxxxxxxxxx>]

I have 
been considering adding a backup ISP to my LAN. I now have cable service and am 
considering adding a DSL line. Does anyone know if they both can be fed into a 
router or hub in such a way that if one is down it will route traffic 
automatically to the other. Seems like this would be a common issue but I have 
never seen anything on it or must I manually switch ISP's.
