Using Conduit?

Ed D:
Hello everyone,

I am going to be working from my home in about two weeks, and ordered a POTS business line today from AT&T, our local phone co.  I also ordered a broadband cable line to be installed.

Both the phone wires and the cable come into the back of the house and directly into my workshop.  There are several fluorescent fixtures in there.  I want to shield the phone from any interference.

Since there is no ceiling in the workshop, and I can run wires easily between the ceilings outside the shop and the floor above, running wires is a piece of cake.

Then I started thinking (this can be a VERY dangerous thing!)  I wondered about running conduit to shield the phone wires, and maybe even run the cable thru there as well.  Then I have my home phone line coming thru the outside wall as well.  If I run that to my home office room, that would be kickin' for me.

So, I have some questions...

I can pick-up conduit from Lows or Home on the Range Train Depot.  Is it OK to run all three sets of wires (home phone + business phone + cable broadband) thru the same conduit, or should each phone line be in a separate conduit (with one phone line sharing the conduit with the broadband cable) to avoid crosstalk interference on the phone lines?

Do I need to use any particular kind of wire for the phone lines?  I have heard of twisted pair, shielded, etc. but I want to do this right the first time.  I may even rewire the entire house for phone service so I have jacks in every room.  (A chicken in every pot and a phone in every room!)

Any ideas or help is appreciated.  I gotta get this done toot-sweet as the new phone installs on May 6th.

Thanks!
Ed

Hi Ed:

I'm no electrical engineer, not even close. I am a phone installer though with 35 years experience. Respectfully, I think you are wasting your energy messing with conduit for phone/tv/internet in a house.

Good quality RG6 coax is very well shielded. Phone lines don't really need to be shielded but using CAT5 cable will be real good. Home run each phone jack to a central place or even to the NID (phone protector). I'd run them to a distribution spot that is fed by a CAT5 from the protector and terminate everything on 66, BIX or 110 blocks and use jumper wire to loop the phone line to each jack run at that point.

No problem having more than one phone line in the same CAT5 cable. Put them on the blue pair (green/red in jack) and the oronge pair (black/yellow in the jack) and then you can plug in a 2 line phone and pick up both lines or use a 2 line splitter (looks like the usual double jack adapter but splits out each pair in the jack to its own jack) so you can plug a phone into either line easily without having to mess with connections at the distribution point each time you want to rearrange things.

Hi Terry,

Thanks for the advice.  But you kind of lost me on a couple of things (I'm not well versed in the finer points of hooking up stuff.)

Sounds like I should run a separate line for each extension instead of daisy chaining them.  That is OK with me.

I'm totally lost on what "66, BIX or 110 blocks" are, and where does one get them?  And not clear on what "and use jumper wire to loop the phone line to each jack run at that point" means.  (OK, maybe I'm a little dense.  But that never stopped me before.)   :D

Thanks,
Ed

Don't worry Ed,
The base concept is that each jack should be "Home Run" to a central point. (seperate cables)

This point is best located in  the unfinished utility room.
A separate cable will be ran to the Demarc (D-Mark) Demarcation point.

We can walk you thru it as needed.  It is pretty straight forward.
