I've used modems on second lines connected through the yellow/black 
pair in a residence (actually, several different residences) and 
never had a problem.  

Remember -- as soon as that phone cable leaves your house, it 
immediately goes into a big fat cable with literally hundreds or 
thousands of other pairs of copper wire.  If "crosstalk" was going 
to be a problem, you'd have already run into it!!
