rj 31x splitter?
So that's the security system, and there's this little box.
The white cable comes from the house, and the 31x end goes to the security system.
I want to get DSL.
I want to split the rj 31x female plug to a rj 31x female and a normal rj 11 cable to plug my dsl modem
is such a thing possible? I don't think it is because of the requirements for alarm systems to be able to seize the line. How would I connect a DSL modem from here?
EDIT: also there are rj 11 jacks in the house and I could use those, but it would be so much cleaner if it was in the alarm system room as that's where my router is.

You will not be able to split the rj31x its self, but could open it up and connect another jack to its output feed to the rest of the house and place it outside of the alarm box.

Get an RJ31x DSL filter and connect it per the instructions, then connect a new phone jack to the RJ31x OUTPUT side.
Sorry but, what rj31x output side?
If I get a rj31x filter then it will only have one female rj31x input, and one rj 31x output to connect to the alarm system.
The box that's dangling in the first picture is where the line comes in. That's the screw terminal
Is my best option to splice a phone line cable, and connect my dsl modem to the screw terminal along with the alarm system cable, and then attach the filter to the end of the screw terminal?

The RJ-31X jack is designed to cut off all house extensions so the alarm panel has exclusive use of the phone line when it goes into alarm and needs to call out. If you were on the phone when the panel went into alarm, you would be cut off. If you pick up an extension while the panel is calling out, the phone would be dead.
In your situation, the white line coming into the RJ-31X jack should be the incoming line (not just another extension), and the grey, flat cable connects to the alarm panel. There should be another line coming out of the RJ-31X jack connecting the house extensions. If I remember correctly, the incoming line connects to terminals 4 and 5 and the line to the house phones connects to terminals 7 and 8 in the jack. I may have that reversed though.
The problem is, from your picture I only see one line coming into the RJ-31X, aside from the flat, grey cable going to the alarm panel. Where's the line to your house extensions?
Unfortunately, some alarm installers will just run an extension line to the RJ-31X jack. This eliminates any benefits of the RJ-31X and allows a would-be burglar to simply pick up any extension preventing the alarm panel from obtaining exclusive use of the phone line.
Think of this like trying to make a call from one extension while someone else is already on a different extension.
To answer your question about how to hook it up, you could bring the line from the street into an RJ-11 jack. From there, you can connect a DSL splitter with a filtered side and a non-filtered side. The filtered side would then connect to the RJ-31X (where your existing white cable connects) and the non-filtered side would connect to your DSL modem.
This is assuming you have the correct setup of the RJ-31X, which as I explained above, it doesn't look like you do.
Hope that helps.

Normally they only use one wire to the alarm, 1 pair in, 1 pair out. If you open the RJ31X jack you should see 4 connections. One pair is input and the other pair is output The RJ31X filter lets through DSL all the time, even if the alarm takes the phone off the hook. So if you open the RJ31x you can wire a jack off the output side. Just make sure all your other phones have a standard DSL filter.

So, best option to wire DSL with the screw terminal?

I am not sure how is this is wired. I am pretty sure that 4 pin cable to the screw terminal is where the line enters the house. Then the alarm system has outputs for the phone lines.
Wouldn't the best option here be a NID splitter and run a new IW from the NID to the modem of the unfiltered port, and reconnect the phone IW that feeds the alarm right at the filtered port on the NID splitter?
| NID splitter is the best but always requires dedicated wire to modem.|
RJ31X DSL filter allows alarm to seize phone line but also passes DSL signal at all time.
1) Install RJ31X DSL filter per manufacture's instructions.
2) Wire, outside the alarm panel, a telephone jack (RJ11, etc) from RJ31x output side to attach DSL modem.
3) Ensure all other phones, answering machine, etc in home have a DSL filter properly installed.
4) Call alarm company and have the account placed in test mode. Place a phone call from your home phone and set off the alarm. The phone call should disconnect and when you call back the alarm company they should see the alarm event was transmitted. The DSL modem should not loose connection during this time period.
