Some Techno-info for phone cabling,
|
|
Most new business phones are currently being wired with "4 pair" cable.
|
|
this has been going on for quit some time. here are the color codes
|
|
and some of the common uses of these wires.
|
|
|
|
|
|
Color codes.
|
|
-------------
|
|
|
|
The cable is Usually grey.
|
|
|
|
The 4 pairs of wire inside have 4 colors: blue, orange, green and brown.
|
|
|
|
"4 pairs" of wire means "8" wires. (no shit)
|
|
|
|
Each pair is twisted together. thus 4 twisted pair. (no shit, no shit)
|
|
|
|
The "blue" pair consists of a blue/white wire and a white/blue wire.
|
|
this means:
|
|
the blue\white wire in the pair is mostly blue
|
|
with a white mark here and there. the white/blue wire is mostly
|
|
white with a blue mark here and there.
|
|
this goes for the other three colors also.
|
|
|
|
thus so far:
|
|
|
|
1 cable = 4 pairs = 8 wires
|
|
|
|
1 blue 1 white/blue
|
|
1 grey 2 blue/white
|
|
(or blue or clear)
|
|
2 orange 3 white/orange
|
|
4 orange/white
|
|
|
|
3 green 5 white/green
|
|
6 green/white
|
|
|
|
4 brown 7 white/brown
|
|
8 brown/white
|
|
|
|
* It is "standard" to refer to these wires in the above order.
|
|
|
|
|
|
|
|
|
|
|
|
* the dominant white of each pair is like a ground to the dominant color.
|
|
Think of them as four different speaker wires in one cable.
|
|
|
|
Are we getting any where yet?
|
|
|
|
*Note
|
|
--------
|
|
You should not play with these wires in "Your" place business. In some
|
|
phone systems you can Burn-Out the KSU if you touch/short the Pair.
|
|
(Now-a-days the system is usually protected from this.)
|
|
hmm... your boss will get shorted(temper) and you will get burnt!
|
|
|
|
|
|
Uses
|
|
--------------------------------------
|
|
Some background:
|
|
In most cases these wires lead to a "KSU". It is like a phone server
|
|
that lets many phones share a few "Bell" lines. The phone uses the
|
|
white/blue pair, and sometimes also the white/orange pair (meaning both
|
|
pairs simutainiously).
|
|
|
|
Sometimes there is more than one "item" on a cable
|
|
------------------------------------------------
|
|
In some cases a phone might get hooked up to the white/blue pair; and
|
|
a MODEM! or Fax to the white/orange OR white/green pair.
|
|
If there is a modem/fax line, It does not go thru the KSU. It goes
|
|
directly to a "Bell" dial tone. isn't this fun? ;)
|
|
|
|
|
|
Free long distance?
|
|
-------------------
|
|
In some really old buildings, Its been heard that a phone man will take a
|
|
wire out side of the building to get a line "down stairs and five rooms over."
|
|
Or they may run a line to the biulding next door. My cable tv guy ran my
|
|
cable out near the basement window and up to my 2nd floor.(dick-head!)
|
|
|
|
(get your laptop and modem ready, next we'll make a "jumper".)
|
|
|
|
A quick lesson on 25 pair cable
|
|
-------------------------------
|
|
25 pair? holy shit, thats 50 wires!
|
|
Yep, the cable is about 5/8 of an inch round. It uses the same scam, I
|
|
mean scheeeem, as the 4 pair.(but different)
|
|
|
|
Main rule: "Like" pairs.
|
|
|
|
blue orange green brown and slate(gray).
|
|
|
|
white Wht/Blu wht/orng
|
|
Blu/wht orng/wht ( a l l l i k e b e f o r e )
|
|
|
|
yellow ylw/blu ylw/orng ylw/grn ylw/brn
|
|
blu/ylw orng/ylw grn/ylw brn/ylw
|
|
|
|
black blk/blu
|
|
blu/blk
|
|
|
|
violet ( y o u f i l l i n t h e r e s t )
|
|
|
|
|
|
red red/blu red/ylw
|
|
blu/red ylw/red
|
|
|
|
|
|
|
|
What else about 25 pair?
|
|
------------------------
|
|
It is usually used in pairs. If you were looking for Dial Tone you would
|
|
First check the wht/blu pair. and work your way down all the pairs with
|
|
white, Then check all the pairs with yellow, and so on.
|
|
|
|
*Note
|
|
---------------
|
|
UnAuthorized "Pair Checking" may be viewed by your piers as UnEthical. :)
|
|
