Change a Cat 5E jack from network to telephone

I'd like to know if all I need to connect is the red and green (since I only have 1 phone line) and if so, how do I know which "slot" of the block they need to be punched in to.
Shahrum....the 'typical' phone plug (4 pins) uses the two center pins (2 & 3). If it is the 6 pin flavor, it will be pins 3 & 4.

In your case, based on the photo, your green and red are you phone wires to the phone.

On a RJ45 jack, the two center pins (4 & 5) are typically Blue and Blue/White.

So, you would need to punch your green and red into the blue and blue/what slots.

Note...the phone is not polarized....it does not matter which is which.

And...like Zappa said....while an RJ11 plug will fit into a RJ45 jack, it could damage the two outside pins or cause them to bend over and come in contact with the adjacent pins.

Thanks for the replies...

If this is my telephone distribution block, and I am connecting a telephone cord to it, how do I know which slot the green and red wires should be punched into? the one on the left of the colored line or the right?



And why are there uncolored (plain white) sections?

Those are your 'color'/White pins.....

So, Blue will be blue top and bottom....Blue/white will be no color on top, blue on the bottom

So I think I may be mis-aligning the wires in my photo then. I thought the wires would "slide" into the gaps and be punched into them as shown in the photo.

If I were to punch the red and green wire, exactly as they are positioned in the photo, would they be in the correct positions?

My bad.....My last answer was a rush answer....I thought I was looking at the Ethernet punch block.....(trying to mult-task...not doing a good job)

The 'blank' side is the 'other side' of the connection.....so, yes...it looks like you have the wires in the right place

Okay good Still waiting on my punch tool to arrive tomorrow and will give it a shot. Guess you can use either side of the color then?

Indeed, on CAT5/5E there is no red wire. You may see red, green, yellow, and blue on the old-school wiring prior to 1988 when the FCC approved CAT-3, or on the silver flat cables that are meant for attaching equipment to the jack and have no business being in the walls. So I may be misunderstanding, but if you have CAT5e in your walls then line 1 should be Blue/BlueWhite on the center pair like rjniles said. Otherwise, line 1 will indeed be red/green.

The red goes in the first slot (blue), the green goes in the slot next to it. The pairs need to be kept adjacent.

If you slide the conductor into the slot you can hold the punch it down with a small dull blade until you get your punchdown. Just press above and below the connector.

My home was built in 2009 if that helps. For clarity sake, my original question (post #1 of this thread) was how to turn a Cat5 jack into a phone line. I think I'm clear on what needs to be done there, but before doing that conversion, I wanted to first connect a phone cord to the "telephone distribution" (not the CAT5 distribution) block within my structured wiring cabinet.

I think then that your comment is still valid, about green and red being adjacent, however in this case I am connecting them to their matched colors since I am right now plugging into the telephone distribution and not the cat5. It's possible that I'm confused and that the phone distribution and network patch panels are on in the same.

You can use the other phone connections as a go by....it looks like from the pic that they are punched into the 2 center connections.. (I assume red and green), even though their actual wire color is something else.

Seeing how your phone cord that you have been showing us is the traditional setup....red and green on it will be for the phone....so punch those wires into the same relative positions as your other lines.

Confirm...you only have one phone line?

That's right, I'll give it a shot once the punch tool arrives. Hopefully no one else chimes in between now and then with a different story I think I'm finally beginning to understand this, I just don't have the tools to test it at the moment.

Punch the red in the slot next to the blue. Punch the green next to the red. You cannot use the orange and green. They are not paired in the terminals.

You could strip a little insulation off of your wires, hold the phone up to your ear, and touch the metal at the bottom of the slots to confirm.

Looking at the white block at the top, it looks like the white with blue is in the first slot, and the blue is in the second slot. That should be your incoming phone line.
Picking any of the white blocks that is un-used, put the green wire in slot #1, and the red wire in slot #2.
