- Cable Question - CAT5 / Phone
- Posted by Steve on September 1st, 2003
Hi all,
Building a new house and builder says he runs CAT5 instead of Bell Wire
(phone) and that I should be able to change faceplates and use other 6 wires
for CAT5.
1. Doesn't phone need solid gauge Bell wire for good voice and 56k modem?
2. Can I really get GOOD 10/100 over a "modified" CAT5 setup?
3. Are there any other problems (cable stupid here) in running 10/100 and
phone in same cable?? Or should I insist on him running real 2-pair phone
and "un-split" CAT5??
TIA, Steve

I wouldn't even f*ck with it.
The wire is cheap if bought as a roll, and it'll never be easier to run the
wire than while the walls are open studs.
Insist. Stamp your feet. Or sneak in and do it yourself.
Fixing it later will be a bitch...

All major office buildings, etc. use cat5 for everything.
The only thing I might do different is run two, one for phone and one for
data.
It's high grade twiosted pair and is better than the old bell cable

I'm not a technician, but I don't think you'd have any problems with what your
builder is proposing. CAT5 cable comes in both stranded and solid gauge, and
it's typical to use solid going from jack to jack, while stranded is terminated
with plugs (e.g., patch cables). The issue is more about how flexible the
cable has to be. I'd be surprised if the builder didn't use solid inside the
walls.
There's nothing special about "Bell" wire. In contrast, CAT5 is designed for
minimal crosstalk between 4 pairs while carrying signals of at least 100 mbps,
so your modem won't have a problem with its puny 0.056 mbps data rate.
Ethernet only uses two pairs, with the other two pairs in a standard CAT5 cable
remaining unused, so it is possible to split the cable and use the other two
pairs for phone, intercom, or even a second ethernet connection. I don't know
if a second ethernet line would run at 100-mbps, but it works fine at 10-mbps
and I've heard of many installations that do that in a pinch, such as when
another ethernet line is desired but the wiring is already in place.
POTS+ethernet shouldn't have a crosstalk problem.
Having said that, though, daytripper has a point -- it's cheap to run wires
when the walls are open. What your builder proposes probably makes sense for
owners who wouldn't otherwise be installing a network. I can imagine an owner
saying, "no, I don't need wiring for a computer network," and the builder
saying, "fine, but let me do it this way so you can change your mind later."
If you already know you're going to spend the money for network cabling,
though, it feels like this is compromising.
Just my non-technician two cents. When I remodeled some of the rooms in my
house, I put in four-port wall plates in each room for two phone lines, CAT5
ethernet, and RG6 CATV.

fwiw, and where I was coming from: the networking world *already* uses all
four pairs in a standard CAT5E cable. And it's not hard to envision a few
years from now that gigabit will be commonplace...
....except where lack of foresight reigns.
It doesn't make much difference what you run for the phones (you'll probably
be using digital phones in a few years anyway ;-) but I'd treat that network
wiring with more respect than this builder does...

...or run Cat5 for voice and Cat6 for data
