one DSL filter and connect
all the analog phones and old wiring to the other side of that filter.
Anyone running DSL should have SQM active in their router. This can make the situation workable even with Dropbox or Windows cloud trying to upload everything.
I'd go one step further, in fact I did, back when I ran DSL, and that was installing a whole house filter a couple of feet from the NID. The modem plugs directly into that, the rest of the house, if applicable, is plugged into or connected to the designated port/posts on this device. That's about as good as you can get for DSL isolation and allowed me to run a 99% RCO with over two years of uptime on a single line synch.
I ran CAT6+ from the NID into the house into the splitter and had the modem directly connected at that point. I then had a run to my router from the modem.
There are also filters that are able to be snapped directly into the NID, but that wouldn't have worked in my application.
