Hi guys
I have this dilemma. I have two cat3 wires: one used to be for phone and data in front of the store .the second one is new tap that needs to be connected to phone and data jack as well in the back of the store . I am not sure how to wire them . I have not done that before. I am always ready to try new things. there is always first time for every thing
I greatly appreciate any help or suggestion on how to do this
Thank you
 
Phone lines should work fine using Cat-3, how many pairs are in each of these cables?

Most of the "data" lines these days require Cat-5 minimum ....

What type of data protocol are you using?

Do you need color-coding/terminating charts for T568A/B, or USOC?
 
Think Spider web from the Center( your demarcation point)

Run individual lines back to your phone useage points. I assume one Cat 3 is for your existing 2 line phone service (as you described) your second Cat3 should be for you internet/ web/ server.

For your second Cat3
You need to look up RJ-45 (image google) jack for CPU interfacing and I beleive its six wires used in standard CPU /small office,
router - networked Cpu's

Again a wire for each CPU to connected to hub/ Router, a single Cat3 from router to Phone or cable / I-Net interface.

Good point on CAT 3 verses 5, I didn't give it a thought!

Cat 3 is suitable for 10 Mbit communication speed, which is fine for most people nowadays unless you're transferring a lot of files on an office network. Google for a color-coded wiring diagram of EIA/TIA 568-B terminations and use the wires in the Cat 3 cable for the green/green-white pair and the orange/orange-white pair. The blue and brown pairs are unused at 10 Mbit and 100 Mbit speeds. I would suggest using a wiremapping tester or some sort of certification tester to ensure that the Cat 3 cable is terminated correctly. The Fluke 620 and Fluke Microscanner are some wire mapping tools. The 620 is technically obsolete now but works great. You should be able to purchase an older Fluke DSP series certification tool for a couple hundred dollars on ebay which will perform the wiremapping and actually certify that the cable meets the required frequency and cross talk characteristics for Cat 3.
 
Nafis,

You will need to be more specific as to what type of "data" jack your trying to run. Reason I ask is in your post you are saying you only have one cat3 to the front and one to the rear - right?

Cat3 can be made with 2 pairs (4 wires) or 4 pairs (8 wires) [or more]. It is important to know to assist you better.

I really thank you for your respond i manage to get the phone / internet to work how ever as i said on my first post this was my first time to tap phone /data wire from existing line . i usually shy a way from the low voltage wiring , I realize how much I do not knew about LV wiring . Do you guys have any book or web site to help understand the wiring technical side?

Thank you

Here is some "white paper" type info at my local/internet
low-voltage vendor:
http://www.hometech.com/learn/index.html
If you poke around the site, there is more than just what
is on this page.

Leviton has an OK, but old white paper on their site
on structured wiring. I don't have a link.

There are other sources out there, but I have never seen
what I would consider a concise, well-written training
manual on the subject. It may be out there, but I
haven't seen anything where I didn't have to wade
through a lot of irrelevant info.
 
my office computers are in 568A; one of them is running on two pair cat3. connect 1,2,3, and 6 and you should be okay. i have no network problems with that computer.
