After a horrible experience with any number of installation and
repair appointments with Comcast, I bought my own tools. Lowe's
sells some tools made by Ideal Industries (some made in USA, some
made in China). I probably could have purchased better tools from
Mike Sandman's catalog http://sandman.com/ , but it was an impulse
buy.
My install experience with the last cable guy was a fist sized hole
in the wall when I wanted to add a jack. He had trouble fishing the
cable. I wanted him to use the gang with a phone cable in it that
was right next to the spot be picked. It had the little pop-out
tables to bring in other lines and the wall plate he brought was a
cable/phone instead of just cable, so it made sense. Start inside
the house and attach the cable to the rigid rod and run upward. I'd
help. But no, he knows best...
I joined the two yesterday and repaired the hole. That's what got
me thinking about the other plates in the bedroom and what was
behind those. Closing up the holes stalled my painting project,
though.
I have nothing against buying tools, per se, but I do have something
against tools I'm only going to use once.
The tool you want is called a tone generator.
I have no idea where the other end is.
You guess the most logical path from inside to outside! Look for
evidence of former locations of splitter. If you're lucky, it goes
somewhere close to where the cable comes into the first splitter so you
have a straight run. The purpose of the tone generator is to send a
signal down the wire that you can detect along the way with the probe
that accompanies it.
It's entirely possible that the wire doesn't go anywhere useful, in
which case you can't use it in your current configuration.
Another device is called a label, 'cuz you're going to bring all
your telephone and cable wiring (maybe data too) to a common panel
box in the basement next to your breaker box after tracing and
relocating wire any as necessary, then correctly label everything
so you don't have to redo the same work later, right?
No, the phone/data is on one gang (though no gang exists, just a
hole int he wal), and the cable was dropped in the wall behind
another. Both between the same 2x4s.
Do you have separate wires for phone and data? Is your router in the
basement? How do all these runs terminate in the basement?
Check the type of coaxial cable. Cable with much higher quality
shielding is being installed these days because it helps prevent
interference that can mess up data over cable, especially. You
want to use quad-shielded RG6.
Probably already twist over each other. I actually don't know if
the data works. The house is wire with Cat5e in all rooms, but I
can't find where they might have kept a hub. I don't see them
coming together anywhere. I sure what to find out at some point.
Then it sure sounds like you'll get much more than one use out of the
tone generator I suggested you buy.
Given the huge quantity that four-pair Cat 5e is manufactured in,
it's used for voice or data because it's so cheap. You end up with
unused pairs, of course, but I've read that data and voice shouldn't
shair the same cable.
With overhead utilities, telephone and electric share the same utility
poles and enter the premisis near each other. With underground
utilities, it's likely they share the same trench and one utility
contracted out installation to the other. No, I don't understand how that
doesn't cause interference in the voice cable but it must be heavily
shielded.
With overhead utilities, telephone terminates in an ugly grey box which
houses the network interface and some remote testing equipment. Then it
enters your basement near the electric service.
With underground utilities, if a new installation, legally, you can
insist that the ugly grey box is inside the basement rather than on the
back outside wall so you can have an uninterrupted run directly into the
basement. Telephone companies always insist that every unit must have its
own ugly grey box on the outside, but always remember that's for their
convenience and not yours. For your privacy, you want it inside.
In either case, the telephone wire enters the basement near the electric
service. Electric goes into the panel box, of course. Telephone goes to
a pin block with 20 connector. From there, ideally you would have
straight runs to each telephone jack.
With cable company digital voice, it's back fed through one of the jacks
and the telephone wire is snipped between the pin block and network
interface, probably within the ugly grey box itself.
