Hey guys. Sorry to ask a stupid question, but haven't run into this. I prewired a house that doesn't have cable service to it, and probably won't for quite some time. The home owner is going to use DSL. During the prewire, each room has one outlet with cat5E near the bed location for telephone. And one outlet on the opposite wall with a cat5E for DSL. This outlet also has RG-6 for satellite.
My question is concerning termination. In my structured wiring box, where should the DSL be terminated? Does it get punched down to the tel hub?
I also have one cat5E from my box to the demarc. I was assuming one pair is needed for the DSL. Is this correct?
I know this sounds ignorant, but 99.9% of my jobs are set up for cable internet, and I run my network wiring (Cat5E) to a network punchdown.
For some reason, I recall a prewire I did a year ago. I punched all cat5E to the tel block, the customer ended up getting DSL, and nothing needed to be changed.
Thanks guys....

Side note: I used RJ-45 punch downs 568A at all dsl locations...
I googled, and saw a dsl splitter.
Any thoughts?
My other question is, there is no NID installed yet, Is there a standard pair that the telco uses for dsl? White/Blue is the standard pair for voice.
Can someone step by step this for me? Thanks guys...

This should work. There may be a simpler way, but you should get the idea in theory.

- Bring in your bl/Wbl pair from the NID to your panel.

- Split that bl/Wbl (Y-jack so to speak).

-send one split to your DSL Modem, network out of your modem into your router, term the network cat5's to the router/hub.

-send other split to your teleco punchdown, but splice in a DSL filter BEFORE the punchdown. Punch your phone.

Hope this helps.

Your DSL is likely the same line as your phone line (if there is only one phone line). Split that line to go between phone distribution hub and modem then wire as you would a cable system. I've been thinking about terminating all my Cat5 with an RJ45 at the tub. Then I would connect those to a network distribution module ( i've been using Open House). At that point I can either use the line as a phone or network connection without having to mess around with the wire later. It just means I'll punch down for either phone or network or both if I have to. Essentially I'd be using the module backwards if you get what I mean. I think someone mentioned once that Grey Fox has a product meant specifically for this termination method. I just hate to terminate Cat5 for a phone module knowing it could one day be used for network.

Thanks guys.
I think I follow you.
In my box, Splice the feed from demarc white blue/Blue. Send one wb/b to DSL filter or DSL splitter? Come off the filter/splitter to my tel hub. Other wb/b goes to modem.
So which am I using, a filter, or a splitter?

I just went through my notes for the job.
The customer doesn't need a network.
In his office I had run 2 cat5E to his desk location. One for tel/fax, and one for his dsl modem.
The cat5E with the RG-6 is tel for satellite.
So what are you guys using for tel terminations? RJ45 punch downs 568A configuration, or do you use voice punchdowns at the plate?
Typically when I'm wiring a network, I use rj45 for the network, and voice punchdowns for tel, just so that the customer doesn't get confused.

Yes. The DSL signal is on the voice pair. You need to filter that DSL signal off the pair before it hits your teleco distribution.

If the "splitter" is a DSL filter on one leg (does it have 2 outputs, one saying "to Modem" and on esaying "to phone"?), use that. Send the leg that says to phone to your punchdown.


I use RJ11 quickports for phone, and blue RJ45 quickports for network, that way the customer can never plug in his networked computer to the phone system.

I haven't bought a filter/splitter yet. I will be going back out after the customer moves in to hang a plasma, and install surround. I can take care of that then as the prewire did not include anything but wire, plates, and a tel hub. I would rather use a unit that has an input and then outputs to phone and then dsl just to eliminate a splice.
I think that would look better. Not that the customer will ever pull the panel, just for my personal preference. Who makes one? And thanks for all of your help...

Leviton And D-link offer a couple good solutions that I have used.

Line 1 in (blue/blue white) , filtered out to the punch-down, the non-filtered to the DSL modem.

Unless your modem has a router built in you will need one of them too if your going to more than 1 location.

The routers that I have used all have rj-45 jacks.

A or B has been debated before.... but my vote is for 568A. The blue and orange pairs line up nicely for lines 1 and 2.

I keep switching cans and how I end up wiring them... A lot depends on the customer and what they are paying me... It is crazy how many different ways you can do the same thing.... If you setup everything with jumpers and wire everything 568A any jack can be a phone or a network depending on where you jumped it from. Although not really a good idea, too much op for customer to mess up...

However, I did use a similar idea to enable the parents to disconnect each kids room separately for networking and phone... For when they got grounded...

I was doing a simple plasma over the fp hang along with an X-Box 360 Live Online install. (Trust me, you want to hard wire these things...) Well, the house (not my originaljob) had a USTec box but the room where the xbox lived did not have a network jack, just phone and F. While the house had many network jacks, not one was being used... Even the desktop was setup on wireless.... From the home office, I jumped from the wireless router to the wall plate, back at the UsTec box I used an RJ45 and keystone to send it to the phone jack. The homeowner thought I was the cats meow to turn the phone line into a network.... FYI, The USTEC box was nice, but underutilized and very tight quarters....


Quick trick.... When you run into daisy chain wiring for phone, 1 number, no request for networking... Split the POTS and ADSL close to the demarc using your favorite DSL filter (Leviton here). Put the ADSL on the Orange pair. Most daisy chain I have seen at least wires for 2 pairs, put a regular L1, L2 splitter at the PC location and you are done. L2 into the modem... Or retrim the plate for two single keystones.

You can do the same thing on a 110 block if you want to....

You can save yourself the aggravation of not dealing with the DSL splitter by having the telco company install the DSL filter at the demarc and then tie in the modem at the punchdown and you will be ready to go.

thanks guys. I went out today to trim out, and stopped and bought the Leviton filter. Pretty simple. White/blue punched down to the filter, jumper from the filter to my tel hub. And then put a male RJ45 plug onto the cat5E located in the customers office to be. Plugged it into the DSL filter, done.
Thanks again guys...
