1 edit | Anyone with experience with phone company side of NID/DMARC? I apologize in advance if some of these questions are overly simplistic. I like to take things slowly when starting a new project.
My property has no NID. I live in a third worldish country so I don't even know if that is irregular for here or par for the course. I would not be surprised if they only install them if supplied by property owner. I bought this property and structure, so I basically inherited the work that had been done. I've ended up re-wiring almost everything that was not inside concrete block. Now to the telephone wiring.
The telephone wires that come into the property and structure look a lot like this,
.
I'm not sure if that is exactly the same or not, but it is about what it looks like.
Anyways, instead of normal jacks in the wall all that is currently installed are these guys,
The two wires from that cable I linked above connect to two terminal screws in this jack.
I have an NID on it's way to me along with a POTs Splitter for my DSL. Currently the phone line with DSL has a lot of noise and occosionally drops the DSL despite having a regular cheap filter on it.
My first issue is that it is not easy getting instructions on how to wire the telephone company side of an NID since generally the telephone companies keep them on lock down and it isn't an issue for most people. Considering I don't have what I believe most have coming into my place as telephone cable, how will what I do vary? I assume if there are two terminals I just attach the two wires. Is it that simple?
If I choose to ground it (the telephone company does not) should I ground directly to the grounding rod at the main panel or should I connect it to the grounding bar in the main breaker panel?
My other question involves splitting the line for multiple jacks. I'm just not sure if it's as easy as it seems. Down here I've been told they use these connectors, 
Should I consider finding something else?
Will the DSL line be physically split because of the Pots Splitter? Is Cat5e the same as telephone wire with just a different amount of pairs? I should be able to get telephone wire fairly cheap, although I might be getting what I'm paying for. What would be an example of Cat5e that goes into a new home these days?
Also, I'm not planning on wiring inside any walls. It's not something I have to do. I can do it all on the outside of walls and am only going to two spots that are near each other and not far from where the NID will be. Should it be in conduit?
How important is it to put the NID right where the telephone company cables come in? I can do it, but it's on the third floor right outside a rental apartment and would be better if I never had to bother that space. I could bring it a little lower (it already goes downstairs either by splice or just tied to a hook and re-routed) and have the NID very near my main breaker panel. Which is also near to one of the rooms that will be getting new jacks. I assume this is all relatively straight forward. I've learned a lot and done a lot of DIY electric work in terms of setting up a new breaker box, wiring to new areas, fixing appliances, wiring and maintaining pumps, and other things. I'm nowhere near a pro, but I try to do things the right way and leave a better infrastructure in place than the one I inherited. New projects are always daunting to start so I'm nervous only because I have done no work with telephone wire so far.
If you've made it this far thanks for listening to my rambling. Any information will be positive as the only other options are read, read, read about it and talk to people stateside that aren't specialists but are around this sort of stuff daily.

| The jack you showed is a normal baseboard jack. Common in older homes. Usually used to wire a home that never had second outlets. They'd be wired the same as normal jack. Since you dealing with only two wires, can't see much going on wrong. You'll need a DSL filter for each line, DSL modem as close to dmarc as possible, ethernet to router, computer, whatever.

| Thanks for your response.
I've got a DSL Pots splitter, so I'm hoping there is no need for DSL filters on phone lines anymore.
Do I split one line to two phones in a manner the same as joining two electrical outlets? |

Disconnect all inside wiring from the NID. Install a new pair from the NID to the Line side of the splitter. Reconnect the inside wire you disconnected from the NID to the Phone terminals of the Splitter.
Run a new twisted pair from the DSL terminals on the Splitter to a jack near the DSL modem.
If inside wiring is twisted pair and there are unused pair you can borrow a pair. If it is is not twisted (Quad-four) you are better off running a new pair to minimize crosstalk.
If you have a home alarm you need to make a decision. Easiest thing to do is connect the alarm to the Phone terminals on the Splitter before inside wiring. Inside wiring is connected to the Alarm jack. That way if the alarm needs to dial it is able to disconnect an ongoing phone call. The downside of this arrangement is if someone plugs a phone into the "data" DSL phone jack and is on a call when the alarm needs to dial it will be unable to terminate the call to dial.
