said by dslwanter:I don't think there's too much in the way of difference from filter to filter. DSLAMs give off the same AM radio signal and modems receive the same signal. Only special filters would be one for a wall mounted phone or something.
Any filter should do fine.
Wrong! Either filter will work, but I believe the -2 filter is made for two line phones. Standard filters only pass one pair (line one) through the filter. A two line filter has 4 pins instead of two and passes the second line also. 2Wire portals search line one and line two for DSL, thus they make a 2 line filter in case you actually have DSL on line 2.
