Re: DSL not reaching modem
(That brought up the question of whether an alarm with that sort of bypass spliced at an unlocked NID at the front of the house is completely useless. Wouldn't it be the simplest thing in the world to bypass the alarm?).
No, that would be the second simplest thing in the world. The simplest thing would be just to lift the receiver on a phone in the house and dial a digit. If not for the RJ131X, that would prevent the alarm box from hanging up and dialing the alarm company. So to prevent that, the RJ131X wiring allows the alarm box to disconnect every other phone in the house, then hang up the phone line, then dial the alarm company.
It's only slightly harder to defeat the alarm by attaching something at the NID, but of course no burglar would do that. He'd just cut the cable going into the NID!
Which is easy enough that the RJ131X is kind of pointless in a typical house. But it makes a lot of sense in a commercial building where the phone line is typically hard to get to. |
