Err..not me, but my friend. Well the story goes that he ordered SBC DSL for his pad. Everything's fine and dandy by which I help him set up, but the knucklehead forgets to add one minor but critical piece of information. He has ADT Home Security. I was wondering why no signal from the CO could be reached. Anyways, either ADT or SBC can come and put in a "DSL ALARM FILTER" on the phone box (which to me, translates to an RJ-31X), at the cost of $150-200. My question is this: I've never done it before and have inspected the Networking box at his pad, so what would it be worth to any of us for a DIY? I've seen SOME tutorials online that are "easy going" and the like, but it's not like I want to drop the signal and have rent-a-pigs squirming all over all the place. What to do, what to do? Any idea guys? Pics can be provided if need be.
