I'm running a phone line in my basement to a new jack. Will I have a
problem if I run the phone line through the holes that the cable tv
(and internet)cable runs through? I've read that you aren't supposed
to run AC and phone together, but not sure on cable. Will either
cable, internet, or phone service be negatively affected?

Hi mark800,
  You *can* run coaxial cable (used for cable TV and Internet)
together. Coxial cable is well shielded against inteference, and if
you were to use Cat 5 cable for the phone line, you would have double
protection. In fact, a cable monkey friend of mine pointed out that
such cable is even manufactured as one cable.

You are correct about running electrical cable and telephone or
coaxial cables next to each other.

You can buy a phone/coax cable wall plate combo here:

Hope this helps! Please ask for an Answer Clarification, before
rating, if any part of this answer is unclear.

Please excuse my fumble-fingered typo: I meant "Coax" cable, and not
"coxial" in my answer.

I don't think there will be any problems in doing so. My telephone
line is tied to my cable tv cables and as such I haven't had any probs
so far. There seems to be no interference problems between the two.

Then again it might depend a lot on what kind of cables and technology
is used. I am from India .... :)

Cable TV shouldn't be a problem because the type of cable used
(coaxial) is designed to resist EM intereference and the cable sheath
should provide adequate shielding.

you shouldnt have any problems. ac power is a problem because the high
wattage of current creates a lot of interference. this is not the case
with the kind of lines you are working with.
