Sam can get DSL from Verizon, but he's so far away, he can't get it very fast. So he went with DSLExtreme, which is half the price. Can he get another line and then multiplex it for more speed?
Leo says he can, and there's a product called Fusion that will do exactly this. It's dual ADSL2 lines. The problem is that he's so far away from the network hub, and DSL degrades rapidly over distance. Bonded ADSL will work, and he should ask DSL Extreme if they have Fusion in his neighborhood.
