I've read up on the different filters for the rj31x, and while they seem to
provide a valid solution, can you please explain you "the split filter thing
is a nono if you are a pro"?  Assuming the unfiltered split is solely for a
DSL modem, and nothign else, is there a reason why that config shouldn't
work?

Or is it more of a "dummy-proofing" the home, where you want to ensure that
every outlet in the house is seizable by the Alarm Panel.  It is apparent
that if you disconnect the DSL modem, and plug a regular phone into that
unfiltered jack, that the Alarm Panel will not be able to seize the line if
that phone is offhook.  But assuming that the only thing that ever goes on
that line is only the DSL modem, I don't see why the soln would not work.

Thanks for the info!
