couple questions about installing phone jacks


I thought this was going to be kind of simple but am now confused as I begin this project(s).

I have 2 rooms that have these ugly boxes that stick off the wall (seen on the first pic with the white wall, next to the power outlet and coax), and I intended to swap them with the jacks shown in the second pic.


I also have this ugly jack coming out of the side of a cabinet. For that I was intending on removing it, making a larger hole, and reinstalling with one of the jacks from the photo, but that instruction thing seems unclear - instruction #4 about cabinet slots?

Also, lastly, I guess I never realized there was power for the phones - I guess something needs to power them, but don't phone lines work even when the power's out?

couple questions about installing phone jacks


I can answer the power thing...yes... you don't need other power lines except the phone line itself... and yes... phone still alive when power is out...

I think the "carbinet slot" in the instruction just mean the front hole of the phone jack... as one of my coworker did, she tried to connect the laptop network cable to a phone jack at her desk... then the laptop is a goner... that is what the warning message talking about....

couple questions about installing phone jacks


So I'll need to figure out how to kill power for the phone line separately then, before touching it? Hmm, gonna have to look at that box outside and see if there's an obvious 'off' anywhere, since just killing my fuse box wouldn't affect the phone..

couple questions about installing phone jacks


the power in the phone lineis about 50V and low power to drive phone speaker only if I remember properly and it is not enough to cause any harm to human body... if you still worry...ware a glove... I do a lot of phone line things before and never thought of it being harmful.... kind of in my subconsious that it is safe...

anyway... don't worry about the little voltage... it is negectlable......

couple questions about installing phone jacks


what do you think of the idea of cutting a bigger hole in the cabinet to install the jack/faceplate?

couple questions about installing phone jacks


You have a surface mounting jack now. Do you want to make this a wall mount phone location? If so you would need a jack designed for that function.

If this is just a looks thing..do you want to install a mounting box or are you going to look at the back of the phone jack and risk moving the wire every time you open the cabinet?

For the wall: you'll need to cut a 2x3 hole in the drywall, and put in a low voltage 'Cut in' box.

For the cabinet: That wall is likely only 5/8" thick or around that, viving very little place for work. But you could cut a hole, install the same jack you plan for the wall, and trim it with a wooden cover plate. You would need to devise some sort of cover on the inside of cabinet. Really, If I wanted a concealed look, I'd probably reroute the wire and mount a jack to cabinet underside.

I'd be installing a box (well, I was gonna build my own box to conceal it, didn't even think of using a real box lol.... I'm insanely burnt out and don't know why I didn't think of that. I was thinking how I'd construct a box for it on the inside!). Then on the outside of the cabinet, it'd be a (satin nickel) face plate over the decora-sized jack hole.

This is being done for aesthetics only, we don't even have a landline here, cell phones only . In all honesty I would just rip the whole thing out, but I don't want to go trying to sell the place and it's not wired for regular landlines lol!!!!

That's pretty slick, the under side of the cabinet.... hmmm now I'm not sure where! Part of me wants to just run the wire to the drywall, but I've never done that before and think the chances of it coming out successful w/o me messing up the wall beyond what a faceplate can conceal are too high to risk, so I kinda wanted to keep it on the cabinet.

Depending on the age of your house you may have a network interface on the outside of the house. This is where your interior lines connect to the phone company lines. Look on the side that you can open for a phone jack connection. If you unplug this it will kill the power on the phone lines.

You can also use this point for troubleshooting.

PS, don't believe that getting bitten by the phone line voltage doesn't hurt.

unplug a phone line from a telephone, you see a connector, press your finger against the connector...i.e. basically shorting the phone circuit with your body.... count to 10.... now you are dead... because you just been shocked by the high phone voltage......

couple questions about installing phone jacks


I think it depends, the warnings said it could hit over 100volts... I dunno what that is, let me go check wiki for what tasers put out!

(from wiki:
As the mechanisms of tasers are not very advanced, some people with basic knowledge of electronics have been able to build homemade tasers or electric shock prods. There has been at least one case of students using improvised electric shock prods in a school. In March 2005, several high school students in Maine faced charges when another student reported that they had been playing with improvised electric shock prods and testing them on themselves and fellow students. The devices were made from disposable cameras with a 330-volt electric potential difference, which, while not strong enough to cause severe injury, could (some claim) be fatal to someone with a condition such as heart arrhythmia. [citation needed])

couple questions about installing phone jacks


hahahaha!!!!!! I just realized that I don't need to worry because I've already been shocked by that line lol!


Yeah, when I was doing my stucco, and working in the tight corner where the interface box is, there was a loose wire that (never assume!) I thought was a dead wire. Anyways I felt something on the back of my arm, almost like a light bee sting, and noticed the wire dangling behind me. It didn't look sharp though, so I touched it again, and sure enough there was a very light current going through it! (suddenly realizes, while typing, that probably means the feed isn't running into the house anymore.. gonna have to dig out an old portable phone and see if I can get a dial tone on any of these jacks!)

As a green helper many years ago....The only time i've been "bit" by a phone line was when I used to strip the wire with my teeth(we were all young and stupid once, right??? ) and an incoming call came in on the line. That learned me quick.

The "ring" voltage is around 90V, but very low current... enough to drive the ringer... It'll give you a buzz, but shouldn't kill you... So just DON'T tell your buddies when you're working on the line, so he doesn't keep calling you as a prank...

Just as an aside, if you get ADSL and you're doing any work on the whole system/box on the side of the house, is to install a ADSL line filter. It'll put a filter to the ADSL line for you at the entry point and can improve synch speeds...
