is there a modem that can be used for DSL & Cable?

[ricoman]

I presently have a DSL internet provider and need a new modem. I would like to buy one so that I don't have to pay for fees. However, I can see myself switching to cable in the next year, so I was wondering if there is a dual function modem that I could buy, rather than having to buy another when I switch over?

None I know about. xDSL and Cable are using completely different technologies for encoding the signal.

So, make the math - whether leasing the DSL modem for a year is cheaper than buying your own, then dumping it.
