DSL filter in Alarm system
I am trying to figure out how to wire my Alarm Panel DSL Filter (Z-A431PJ31X-A) Z-Blocker from Excelsus Technologies into my telephone system.
The wiring www.ac5r.org/Alarm_wiring2.jpeg is annotated.
It appears that I need to run a wiring pair from the initial punchdown at Telco Punchdown in the photo to the DSL modem, instead of from the current location at the end of the punchdown lines to the modem.
There is nothing attached now. Next, I should run a 4 conductor line to the alarm panel with the tip and ring lines to the plug base at the panel and tip and ring lines from the plug base at the panel back to the punch down and continue the house lines from there. This rather than continuing the house lines off of the tip and ring lines from the Telco as shown.
I have been referring to this photo
http://home.earthlink.net/~gingerbarth/DSL_006c.jpg
and this schematic
http://home.earthlink.net/~gingerbarth/schematic.html
as points of reference. The alarm system is not currently part of the extant telephone system. The old wiring was abandoned when the structured wiring was installed.
There is currently four conductor wire to the alarm panel as originally wired by ADT when it was installed. Somewhere this runs to the old telephone system wiring.
I can retrieve this orginal wiring intact, if need be.
The alarm panel is labeled Safewatch 2000/ Security Manager 2000. I have a photo of the internal view of the panel, if it might help.

Since you are going to the effort to have high quality wire in your house, run some of the same cable that you are using in the rest of the house back to the rj-31x jack. Take one pair to come from your incoming telco and another pair to return and feed the rest of the house wiring. (This allows your panel to properly seize the phone lines). Plug the alarm DSL filter into the rj-31x jack, and the panel cord into the filter.
The reason I say to use the twisted pair cable, is that I have seen instances of people complaining of DSL degradation when simple 4 conductor is used in this instance. 9 times out of 10 there's no problem, but you can make yourself crazy trying to track the problem down on the 10th time.
I've been insisting on useing at least cat 3 for alarm telco for this very reason.

I finally had enough time to start this rewiring with enough time to undo and reset everything if no solution were found.
I found that the alarm wiring had its own color code. I had to go with the logical approach. I ran blue and blue/white from the phone to the alarm X31 jack and green and green/white back to the phone in the punchdown panel.
I picked up the incoming phone line and went straight to the DSL incoming port. Next down stream, I went to the alarm panel and back, then tied into the house telephones. Everything appears to work fine.
I ran Cat5 wiring and abandoned the 4 conductor wire that the alarm company had used. I tagged the line to and from the alarm, and left a wiring diagram in the panel for whoever has to deal with this in the future.
Now this one more project is behind me.
