NTE5 and XTE2005 questions.

[GSDog]

Hi all.

I would like to replace my old mastersocket with the newer NTE5 one, which I know BT will need to do.
I have bought an XTE-2005 faceplate for the NTE5 (when it's fitted) and I plan to have the router at the mastersocket, but how will this effect sky boxes, alarm systems (which is hard-wired into the phone line), etc?
Will I need to do anything with these? Or do I just install it, move the router to the mastersocket and that's it?

I thought the XTE-2005 filtered everything from the mastersocket, so I didn't need to use those annoying micro filters?
I expect the alarm company will charge a bomb to come round and filter it.
