I'm trying to install a couple of the Leviton DSL Filters into my home panel, and I'm rightly confused by them.

Heres the board:


The problem im having is that I appear to have no dial tone coming from the OUT pair. The DSL jack at the bottom is working properly, and I can get dial tone if I wire the IN pair straight to the telephone block.

I've got two of these boards, and two DSL lines coming into my house. Both boards act exactly the same. The DSL port works fine, but I get nothing from the OUT pair. I've checked my wiring 100 different times, and confirmed the setup with the documentation.

Has anyone else had experience with one of these? What should I be expecting from the OUT pair?

I don't see what you can be doing wrong. If you send the dial in on the IN port, I'm assuming it would come out filterd on the OUT port. You are sending the dial tone in correctly if you're getting dial tone on the modem port.

Never worked with that exact filter. Is there paperwork that came with it?

Here's what I use and works every time.

Thats why I'm perplexed; its the simplest of things.

With or w/o a jack plugged into the MODEM port at the bottom, I get the same results..nothing on the OUT. I've got two brand new boards and they both do the same thing. I'm wondering if it might be a level issue and they're filtering out too much signal. If I understand correctly, the board passes the signal unaltered to the MODEM port, and filters the signal provided at the OUT terminal.

Maybe the filter is killing the signal completely somehow?

Do you have a punch tool? How are you confirming that the DSL port is working fine? With a phone or the modem?

Make sure that the DSL port gives out dial tone, that'll tell you that you put the dial tone in correctly. A solid green light on a modem can come on with only half a pair working.

Why do you have TWO DSL lines going into the house?

I wouldn't think it would be polarity sensitive since manufactures corrected that many years ago. Just in case turn your tip and ring over on the incoming line and see if it makes any difference.

Never used that type, but it looks straight forward. The filter shouldn't affect the voice, different frequencies. It just filters the DSL signal which is higher frequency than the voice. Levels shouldn't be a factor as long as you can hear and talk on the line.

They have to be defective. Most of that stuff comes from China so you have to almost expect it.

Beat me to it, I wonder too. You order 1 physical circuit, and as many PVCs (permanent virtual circuits) as you need riding on it giving you distinct DSL connections. At least for business accounts, for residential use the CLECS/ISPs may not offer this (cheaper) alternative.

For tuf, if the boards are not from a defective bunch, make sure the IN/OUT wires are punched in and CUT correctly. You're also not supposed to use any other filters behind this.

I'd disconnect everything from it and read across the leads of "F1" and "F2" with an ohm meter. These are micro fuses and one of them may be open. That may set your mind at ease if this proves the fault, but it still doesn't eliminate the fact that you have defective units.

Did you call Leviton Tech Assist number listed on the docs? Maybe they had a bunch of bad boards; should have a warranty if so.
