Hi ng, I am pretty confused within the 800 Range of Products. I need a box which does * replace * the DSL modem of a certain user's home office; I think of a unit that does have an integrated one which connects straight to the split box thus emliminating the need of a DSL modem. I am from Germany, I say this because there seem to be country - specific differences between the models. I think it must be somewhere between 827 and 83x ? jt
