Calling any DSL tech people....

Or anyone may have already figure this one out:
Why would a DSL modem and wireless router work perfectly fine connected to one phone jack vs. another. The phone jack that works has 2 CAT5 wires coming into the box...I believe the jack itself is also acting as a junction point.
The jack that does NOT work has one line coming in straight from the phone service panel....why is this?

I'm not sure I have a clear picture of the topology. The only thing that should keep it from working is bad wiring or a DSL filter somewhere in the chain where it shouldn't be. When you say phone service panel do you mean the network interface box that's usually on the outside of a house? Isn't all the wiring coming in from that?

1. Do you have dial tone coming in the the "non working" jack? Or, have you verified continuity back th the subscriber network interface (sni)?

2. Are you sure that the jack in question is connected to the terminal screws in the sni that the dsl signal is coming in on?

3. Are you sure that jack is home run back to the sni, and not connected to some other possibly damaged jack causing a problem?

I've been in the business for a lot of years, and those are the things as a tech I would check first.

1. I do get a dial tone form the jack I cannot get DSL from
2. This one I have to check...
3. The jack in question goes straight back to the service panel outside the house.

Its wierd....the DSL light on the modem comes right on when connected to the previous jack, but no DSL with this jack in particular. Now, the working jack and non-working jack are different types of jacks for some reason. I just don't get it, jacks are jacks, right?

I think I have it figured out....there are 2 main cat5 cables coming in from the service panel outside. On the inside of the service panel, there is a "terminal" called "POTTS/DSL"....I am no expert, but it appears the wiring shows only the upstairs line is set-up for DSL, where the downstairs line (and the non-working jack) are not. :rolleyes:

It sounds like its filter at the main box,So you are correct, you would still have dial tone but no dsl on the other jacks.

Tie the downstairs jack on the binding posts with the cat 5/dsl and you should get your dsl downstairs, but once you do that, I'd put filters on all of your jacks.

I should restate that last post....I'd put filters on all your jacks that have something plugged into them. A vacant jack doesn't need a filter, nor does a dsl modem on a home run.

Some equipment puts enough resistance (my directv receiver for one) on the line, that I would think about it before I put my dsl on that line. In fact I have my modem on a cat5 home run on my line two. (I get two free dialtones for having over 30yrs with a baby bell)

Hope this helps.

I think the jack that works is a Data Jack which I believe can have dial tone and data on it. The DSL modem needs to plugged into this jack. The other is on the other side of filter so it stops the dsl data, leaving the Dial tone only. These jacks don't need filters which are the one you see in the house normally.

Any standard rj 11 jack can have dialtone and dsl piggybacked on it.

But a RJ11 jack can have only dial tone on it, if a filter is used outside.

I suppose. My part of dsl is installing dslam equipment, snd since I haven't been on the res end in 11 yrs, I guess there may be a filter I don't know about (the only place I've seen filters is at the jack).

My bet is if he ties down the IW in question to the bp's in the sni with dsl, he'll get his dsl on that jack.

i have a filter on another pair. I have to run a second line in for my dsl. And they charged me 2 hook up fees after the fact.

I use a DSL at my house and have what's called a Pro job done, where they send a guy out with a truck. Where the filter is installed at the DMark alone with a data line. This way I don't need a filter at every phone jack on the inside. I know BellSouth at the time charged me a fee of $100 for the Pro installation. Now that BellSouth is part of ATT I don't know the current price or if they even offer this service today.

Rivrrat

Now understanding what you're saying, I don't think we even offer that. Truthfully, if that's what I was looking at, I'd rather have the filters at the jack and maintain flexibilty in where I could place my modem.

And all of that said by someone who has their dsl modem on a cat5 home run.

Anyway, if kevhead takes the inside wire in question and ties it to the same binding posts as his dsl is on, it'll work just fine, but he'll need to put filters on the jacks with equipment on them.

My believe is a filter at the DMark is the way to have it. I feel there's more issue's or noise with the filters at phone jacks. Just IMHO.
