DSL Wiring

[srode]

Does DSL use just the 2 network wires or does it also use the tip and ring wire from the phone line? I'm having problems with my do it yourself installation, the phone and DSL are turned on outside according to the phone company but nothing inside. The previous owners had a cable modem phone so that was disconnected and I disconnected the alarm bypass to make sure it wasn't interfering with the phone line and still nothing for phone and the DSL modem is blinking, not on constant so according to the directions is not hooked up yet. Nothing was touched on the network lines which are orang and white with orange stripe, so it should be good and I did do the termination of those to at the jack, with solid orange going to yellow and white with orange stripe going to black on the jack.

srode: DSL uses the same 2 network wires as your analog phone service, but operates independently of the phone service; it can actulally be delivered without an active phone line. Although your problems could be the result of a several different things, I'd begin checking all of the phones to ensure the filters are connected to the phones. Good luck.

Go outside to the phone company box and plug your modem in there bypassing all house wiring. It's the only sure way to determine if the phone company is providing DSL service.
If it doesn't work, one call to the phone company should quickly resolve the problem.

What do u mean by 2 network wires? It sounds like youre talking about an external POTS DSL filter in a gray box, mounted near the phone co. NID/DEMARC box(the phone line termination box), that has 2 posts labeled network, 2 for voice and 2 for data, such as the one here: http://www.hometech.com/hts/products/phone_data/filters/su-649a1.html. Do u have any pics?

If what youre referring to IS a pots DSL filter, then you wire it as follows:

*2 pair wire from phone co. DEMARC box goes to 'network' posts in POTS DSL filter box(u can think of the network posts as the filter's input posts)

*2 pair wire or wire feeding jack that DSL modem connects to goes to 'data' posts

*All remaining wires that feed jacks that phones plug into goes to 'voice' posts

Disregard TIP and RING- this has to do with the polarity of the wiring and seldom causes a problem when wired backwards. Unless u have a tester(radio shack sells a cheap plug in tester) to verify the polarity, then theres no way to tell. I come onto job-sites all the time where half the jacks are wired in reverse polarity but never caused/causes an issue!

Even if nothing was supposedly changed w/ the wiring, I would still verify that signal is present in the DEMARC box and then that signal is getting to the filter from the DEMARC box. Then verify the filter is outputing signal on the 'voice' and 'data' posts.

To test: in the DEMARC box, there is a 'test' jack u can plug a phone into to check for signal. Then to test signal at the filter, take an old phone cord, plug the cord into a phone and cut the plug/end off the other end of the cord, strip insulation from red and green wires and attach to voice posts, listen for dial tone, then connect to data posts and listen again!

Heres a run down on the why and how of the filter: A DSL modem and the signal sent by the phone company creates noise that sounds kind of like an analog modem or fax machine. Because its a digital signal, the noise can be filtered out so its not heard on the phone. This negates the necessity to have 2 separate phone lines.

Yellow and black at the jack is line 2 get on the other pair of wires

You either need the DSL modem plugged into the same jacks as your phones are, and then have DSL filters on each and every phone in the house, or you need separate circuits in the house for phone and DSL, with one filter where the two split off.

Around here, when Ma Bell sets up DSL for you, they tell you to plug it into a phone jack, and then ask you how many other phone devices you have in the house, and send you that many filters to install.

OSU69 has it right, take the cable modem to the interface box and plug it straight into the phone company, with the rest of the house unplugged, and see what you get.

DSL is on tip & ring. Usually white/blue, blue/white in multi-pair cable, & red/green in two pair. At least that's the way we wired 'em before *everyone* became telephone techs. If you have dial tone that's where it'll be. If you have just DSL then you'll have to use the DSL modem to find it.

The inside jacks/connectors are tip/ring = red/green or w/bl bl/w

Not always !

Yellow and black were also used for 24VAC(?) for the dial light on Western Electric Princess and other handsets.

For those of you who still have wired phones (even if the come off of a cable box) the simplest way to wire up new lines is RJ11 splitters and RJ11plugs, cheap crimpers and the flat phone wire. The wire, crimpers (cheapest one you can find) and plugs can be bought at Home Depot, Lowes or even Target or Walmart. With 100' of wire it should be less than $20.

In a convenient place, mount a splitter like this.

Then just run all of your individual cables back to here !

Thanks guys, I got it working on one of the Jacks now so the wife is happy because she now has her internet service. Now I just need to get the jack in the office where my desktop is to work so I can move the modem closer to the computer since it uses a LAN cord. Getting close and for online at least finally. I'm impressed to see we have 9mbps download speed on DSL here which is about what we had with Cable internet in Iowa, maybe a bit faster.

Let's stick with this century to simplify responses, eh?

In a previous post you stated this was a combined phone and DSL service. If that is the case you can simplify your trouble shooting by looking for 48 VDC on the wire pair that is active.

Also most DSL modems today also have a wireless router so you may not need to move the modem to your office desktop for a LAN connection if you use wireless.

In today's world you will want wireless LAN in your home if you do not already have it.

Maybe the guy lives in a house from the last century?
At least now if he sees a little wall-wart transformer with black and yellow phone wires attached, he'll know why.

I have a couple of those old transformers in 'inventory', the ones made by AULT were known to catch on fire, there was a recall. http://www.beatriceco.com/bti/porticus/bell/pdf/ault-transformer.pdf

I always prefer a DSL splitter installed at the NID with a homerun to the modem, but rarely see it in practice.

Huh? Tip + ring is a polarity term and has nothing to do with what pair a DSL signal is on. I've wired houses with 2 phone lines and the DSL happened to be on line 2 which is yellow and black in a 2 pair cable! I believe the OP was referring to a DSL POTS splitter thus the reason he mentioned 'network' wires. 'Tip' + 'ring' is labeled at the top of most POTS DSL splitters to indicated which terminal post is which!

With todays modern phones, correct polarity of tip + ring doesnt matter. Correct polarity of 'tip' and 'ring' is only critical when it comes to T1 lines, PBXs and some trunk equipment!

U hardly see them anymore because someone invented a better solution- the inline DSL filter slitter dongle. Easier than running a dedicated line or changing the wiring around at the DEMARC but puts guys like us out of the dedicated DSL line wiring business!
