Questions about phone jack wiring for Comcast cable


Hi, I live in Montgomery County, MD. When I moved to my new town home, I had Comcast installed everything for me (TV, internet and telephone). I had the Comcast pro set up my cable modem on the 3rd floor where I had my home office. So, the phone wire is also connected to a phone jack on the 3rd floor.

Now, I moved my home office to the basement, so I have moved the cable modem to the basement as well for easier network wiring.

I am interested in wiring the phone jack in the basement to my cable modem myself, but got confused as I have never done this before.

In picture 1, you'll see the Comcast pro's wiring of the phone jack on the 3rd floor. I am confused by connector A and connector B there. Do I have to have them?

Picture 2 shows the current phone jack in my basement. I am wondering if I can simply detach those wires shown in picture 2 and directly connect the white and blue wires (shown picture 1) to the basement phone jack.

Any experienced? Please advise a first-timer? Thanks.

Questions about phone jack wiring for Comcast cable


The parts labeled A and B are wire connectors for small gauge wires, just like a wire nut.

OK, thanks, let's get things done little by little.

So, they are wire connectors, my question remains: Do I have to have them in my basement phone jack wiring? Sorry I know nothing about phone jack wiring now, and I'm trying to learn a little from here.

No a terminal block such as the one in the second picture is actually a better solution.

Ring Ring........your phone is ringing

Why not just plug into the jack that is there? I might not understand how the cable is run tho.

Speaking of Picture 2, so, you are saying that I can indeed detach those current wires and wire the blue and white wires (shown in picture 1) to the basement phone jack), correct?

Yes, that's the best way to try it out, but before I know what I am doing, especially, I want to dismantle the phone jack on the 3rd floor, I wanna make sure I do it right if I do.

Yes wire the phone out from the cable modem to the block, make sure the original wiring coming in from the outside is disconnected. If all the phone jacks in the house are wired correctly tying onto that block should enable the phone jacks throughout the house.

Not yet, actually, please look at picture 2. When I connect the blue and white wires in picture 1 to the basement phone jack, how can I make sure all phone jacks in this house are properly connected? Thank you.

In picture 2, I see that 4 wires (blue, yellow, black and red) are connected to the phone jack. Which two am I supposed to replace with the blue and white wires in picture 1?

Plug your phone into a jack, try all combinations on the terminal block until your phone has a dial tone or

trace the original wires brought in by the phone company (back before cable modems) disconnect those (2) wires and connect the blue and white from the cable modem.

If that doesn't work call me......

Ok, Comcast has an outage in my area. I am replying thru the iPhone app of this forum.

Should I replace bolt 1 and bolt 2 in Picture 2 with the white and blue wires and don't touch bolt 3 and bolt 4? Will this make sure all phone jacks in the house are connected?

Is the new cable from the Comcast box bringing phone service into the house?

It would be screw terminals 1 and 4, not 1 and 2. Red and green, black and yellow is the old pairing color scheme.
