| DSL not reaching modem
I recently had dry loop DSL installed at the NID, but my modem (Speedstream 4100) doesn't recognize it at the phone jack (blinking red light). The DSL is active, because I can hook the modem at the NID and the light turns green.
Here is the scenario.
There used to be an alarm, but the alarm was not active for years and finally the control panel was removed. I assume there is an RJ131X, but I don't know where it is, so the line was just looped back at the control panel site. That means the RJ31X is still in the system somewhere. The DSL installer commented on the fact the alarm (specifically the RJ31X) was interfering with my old DSL which is shared with my phone line.
The house is wired with 6wire blue, green and orange solid and with white dots. A 4 wire (green, red, yellow, black) was spliced between the blue wires and the NID, and the green and red ran to the RJ31X and the alarm and then looped back to the NID on the yellow and black. I told him to go ahead and wire the 6wire straight to the NID to bypass the alarm circuit with the RJ31X. (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?).
So now the blue, blue/white is still line one for the phone (with no more alarm circuit), and I wired the green,green/white to the new DSL line. I wired the green wires at a convenient jack and got nothing.
The kitchen wall mount jack has the orange wires wired in to line two, but I don't see any reason why they would have done that. The orange and green wires at the NID were never used.
Is there anything obvious that could be wrong? What I really need is a tone generator to test whether the line is connected to the jack, but I won't be able to borrow one for a week or two and I would like to get this working before then. |

| The RJ131X is just a special phone jack for the alarm
If the alarm is not used you may be able to just disconnect the phone cable that's connected to it

I been able to trace phone cables using the dial tone, handheld phone and a test cable

| It's a DSL line so I didn't think there would be a dial tone. In any case, I am able to plug in my modem to the jack which I believe simulates for DSL essentially what you are doing with dial tone for a voice line.
Since the existing jacks don't have the second line wired in, I am hoping to test various jacks to see if I have a life one, without having to physically wire in the second line to each jack.
I was able to borrow a tone generator at work, so I won't have to wait for my father-in-law to come into town. I'll find out tonight what I've got. It is a 13 year old typical Southern California track home (Pardee), so I am assuming each jack is spliced into a single common wire. Apparently the first jack I tried does not have all six wires brought out. Hopefully I have at least one jack that does. |

Install a NID splitter, and run a new cable to the modem. It is always better than struggling with dubious quality wiring. |

Install a NID splitter, and run a new cable to the modem. It is always better than struggling with dubious quality wiring. It's dry loop, no need for a splitter.

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. |
