Filtering the entire house requires new clean lines to the DSL modem.
That was easy for me, but is un-common...
Unless your security system has a completely different phone line and number
it would still need a filter in your situation.
Sorry I was no help.

Rick,
No. I do not have a "whole house filter." I use the dsl filters that
came with the dsl modem on those house phone jacks that have telephones
connected. And, I have a "special" dsl filter I bought for my home's
security system. This could have been overkill because the security
system has its' own dedicated line to the out-door phone company ?magic
box?......... :)
