Cable Color Code Identification
3.8 Cable Color Code Identification
The North American Communication Cable Color Code is utilized for the Positron
Teleline Shelf communication cable wiring.
The color-coded cable pairs consist of a Ring conductor and a Tip conductor.
Q
The Ring conductor has a negative DC voltage standing on the circuit
when in an idle condition.
Q
The Tip conductor of a DC powered circuit has an Office ground standing
on it when the circuit is in an idle condition. This DC powered circuit will
function with a telephone type device, but is not limited to that purpose.
Q
The first color of the code is the primary or major color of the conductor.
Q
The second color of the code is the secondary or tracer color of the
conductor.
Q
In the event the conductor is one color only, then that color will be the first
of the conductor code.
3.8.1 Color Coding Example
If a cable pair has two conductors, one is solid colored BLUE and the other is solid
colored WHITE. The BLUE conductor is the ring conductor and the WHITE
conductor is the tip conductor.
If the cable pair has two colors on each conductor, those colors being mostly
BLUE with a WHITE tracer and mostly WHITE with a BLUE tracer, the mostly
BLUE conductor will be the ring conductor and the mostly WHITE conductor will
be the tip conductor.
