Jaxson: No worries, it was written crapily.

Ah, basically are the bits like the ring capacitor etc just not needed any more??

Back in the day the line came into outlets full of electronic components.? These days we just feed the line?straight out to standard RJ45 type connectors.

I know what you mean, Jaxson. The ring was carried from the "master" jackpoint, the one with all the components inside it, to the "slave" or "extension" jackpoints that didn't have the extra components, by use of a third wire. I think these days the idea is that you only use "master" jackpoints throughout the premise, but only have the two wires connected, not three. Note how each of his jackpoints pictured above have at least a capacitor in them, and not the other stuff you used to see inside the old "master" jackpoints.

The colour-coding, as I recall, was white to 5, red to 2, and blue (ring) to 3.

Thanks Frittmann.

So yeah we're just continuing the cabling right to the sockets now, no additional ring components anywhere along the line now.

Is the Your room box the one that is closest to the ETP? As Cyril says, that'll account for the grey cable.

But knowing where/how that turns into the cat5 blue cable (used in the kitchens) is really what you need to find out (unless you can see all that in the back of the same box.)

And as the kitchen ones only have one cable coming into each box there is another junction somewhere. (perhaps involving 1 of the white cables we can see in the back of Your Room box)

The setup goes like this: Road --- ETP --- Main Kitchen --- My room (where I am quite sure the joint is) --- Other kitchen.

My guess is that the kitchens come AFTER your room as they are both blue and the ETP has grey cabling. There looks like a nest of connectors inside your room wall socket cavity.

New BT jacks no longer have any capacitors as all phones now have their own. I'm not sure of the vintage of the jacks in the photos. What do they have on the front of the plastic "2" or "M"?

Hi, I would say they are 2 sockets with ringer support, M ones normally had the test resistor and gas arrestor etc.

I agree, it seems the last photo has more stuff to declare in the wall.

That's right. I used to have to do the same back in the 80's when installing Panasonic SBX systems. Each extension required a "master" jackpoint, and only the red and white wires, no ring wire needed.

cyril7: M ones normally had the test resistor and gas arrestor etc.

Thanks Cyril, I couldn't remember what the other two components were. Gaseous arrestor and test resister. That's it.

If they are "2" sockets why are they even laid out for the old components? I was wondering if someone had used old Ms by removing some components.

A single PCB can be mass produced for both the "2" and the "M" varieties, with the components being added only for the "M" ones during manufacture.

Hi, they could of course be M's but I remember there was a time when 2 where just as shown in the photos, I you say they just modified existing boards.

No, the 2 type only had wiring access to 2 of the jack connections 2&5 with the Krone strips common to one or other. The M type had a wiring terminal for all 6 jack connections. Hence my interest in what's embossed on the front.

Hmm? The Krone strips on a secondary jack would normally have all 6 terminals connected to the PCB individually. See my comment above about the use of pin 3 for carrying the "ring" line. Other than that, I don't understand your comment here, sorry.

A Secondary jack is not a 2 wire jack. There were master and secondary 3 wire types, then 2 wire with a capacitor and finally 2 wire without capacitor.
