DSL install on 2nd Line

[brm5017]

I'm installing DSL for an older gentleman who has a 2 line phone system with two phone numbers. The DSL is activated on the 2nd phone line. I'm having some problems - the DSL cannot see the 2nd line, and is attempting to use the 1st line.

I have already tried a line splitter (ie.. line 1 / line 2 / line 1/2 ). I think it may have been wired wrong, as the phone had dial tone in a difference sequence than what was indicated on the splitter itself. (ie.. tone on line 2 when plugged into line 1 on the line splitter)

Filters have only been used on the line that connects to the phone.

Yes, I have installed many DSL systems.

Any suggestions?

Does the client have two separate lines coming in or is it one phone line that he can have two lines? Maybe the jack you are plugging into is physically wired to use the first line if the two lines are separate.

He has 1 jack that uses 2 lines.

Maybe the jack you are plugging into is physically wired to use the first line if the two lines are separate.

If this is the case, would a custom crossover cable work?

I'm going to try another Line separator to see if the first one I bough was faulty.

I apologize, I'm not making my question clear. Does he have two separate phone numbers (two separate lines) or does he have one phone number with two lines? If it's two separate phone numbers, it could be a physical wiring issue.

Yes, two separate phone numbers.

The phone works perfectly when plugged directly into the jack & when plugged into either port of a standard Y splitter.

I think the DSL is getting confused when it is plugged into that jack as it has two lines associated with it. I guess thats kind of obvious lol :D. If you have access to a jack that has only line two available, plug the router in and see if it connects. If it does, then I would run a second jack with only line two for DSL.

If you have a single jack with two lines its a RJ14, The outside two pins are the line 2. DSL filters are going to be dedicated to the center two wires (line 1).
Your option is to use a filter in the Network interface and a seperate wire to the modem, or do some custom wiring at the jack.

Nice to hear from a man who knows what he's talking about. :)

DSL splitter is not an ordinary splitter (like telephone wire).

I guess it must be coming for the the provider. Ask your provider...

There would be another possibility in the UK.

BT allow a second different number on one line for a small extra charge. You can only use one number at a time however as there is no extra BT wiring. All the switching is done at the exchange.

This option used to be (is) used by people/organisations wanting a fax on a different number at less cost than paying for a genuine second line.

Are you in the UK?? Also what I would do is find out which pairs the second and the first lines are running on. Then redo the jack to the line that your wanting to make for the dsl in the middle two pins. But I dont know if it is different in the UK then it is here in the USA

You said you're using a "two line splitter" what you need is a "two line inline filter". They are different. Also make sure you do not want to use a "two port filter" as this is different.

Best option as said before is to filter at the NID and run a dedicated jack for DSL.

If wired correctly and using the old 2 pair JK wire, line one should be using the Green/ Red pair and line 2 would use the black/yellow pair. On the RJ-14 jack the two center pins would be wired to the green/red pair, and the outside pins would get wired to the black yellow. Check at the Demarc to see if this is done.
If using Cat5 or Cat6 then the wiring should be line 1 on the white/blue pair with line 2 on the white/orange pair. The jack pins on the RJ14 are the same. If it is an RJ-45 jack, then the two center pins (pin 4 and 5) are connected to the white/blue pair, and pins 3 and 6 are connected to the white/orange pair.
Don’t confuse a line splitter with a DSL filter.
The DSL filter take different forms and depending on what you have is where it is placed.
If you have a very simple cabling setup such as both line one and two come to one jack: then you need a line splitter to separate into two separate ports (one for each line) Line one then goes directly into the telephone. Line goes to a DSL filter, then to the telephone. If there are more than 1 phone in the home, then this setup needs to be done at each jack/phone location.
For a more complex setup, lots of 2 line phones, it makes sense to filter at the demark and then run the DSL component of line 2 on a separate line.
Also note the fine print on what you think may be a line splitter, may actually be a line breakout, In other words, line 1 goes in and line 1 comes out to both output ports.
If you know line 2 has DSL on it and you can’t pick it up at the jack, then go to the source and look for the DSL at the Demarc. If you can pick it up at the demark, then you need to check the wiring and jacks to ensure that it is correctly wired at each end, and that there are no junctions in between that may have been crossed.
