Thankfully, DSL has been around long
enough that by now most alarm techs
realise what it is and know how to deal
with it.  In most homes they simply insert
a plug-in DSL filter that's made for use
with an RJ31X (alarm) jack.

Here are examples of a Splitter/Filter
http://www.bassburglaralarms.com/product_47015_detailed.htm

and an alarm system DSL filter which I sell
http://www.bassburglaralarms.com/product_8797_detailed.htm

The splitter version is intended for use in
an OnQ structured wiring panel.  Stand alone
units are fairly common as well.
