How to count telephone cables?
Starting with the first binder group in the center, the technician counts the cable's groups in a spiral direction depending on the location of the central office or switch. If looking at the cable's core and the switch is in that direction, the groups are counted counter-clockwise. If the cable is the field side, the count is clockwise. There are indicators on the mylar ribbons to know where to begin for each layer and a diagram for the different cable sizes should be readily available for reference.

Each wire is identified by the combination of two colors, one of which is the major color, and the second the minor color. Major and minor colors are chosen from two different groups of five, resulting in 25 color combinations. The color combinations are applied to the insulation that covers each conductor. Typically, one color is a prominent background color of the insulation, and the other is a tracer, consisting of stripes, rings, or dots, applied over the background. The background color always matches the tracer color of its paired conductor, and vice versa.

How to connect a POTS line to a phone system?
If you are using a small PBX or phone system, most likely the POTS lines (commonly called trunk lines) are connected to the system using RJ-11 plugs. If your network interface terminates with a modular jack, then the job is simple: just connect the phone system using RJ-11 plugs. If your network interface has a terminal strip (a place where the pairs that comprise each POTS line terminate at a junction where you directly connect the colored wires), then you would need to either connect the lines directly to the PBX, or connect a modular jack to each of the POTS lines on the strip. Then, to wire your phone jacks, you follow the same procedure as noted above for connecting POTS lines directly to phone jacks.

Overview
Color coding
With the development of new generations of telecommunication cables with polyethylene-insulated conductors (PIC) by Bell Laboratories for the Bell System in the 1950s, new methods were developed to mark each individual conductor in cables. Each wire is identified by the combination of two colors, one of which is the major color, and the second the minor color. Major and minor colors are ch…
Larger cables
For cables with more than 25 pairs, each group of 25 is called a binder group. The binder groups are marked with mylar ribbons using the same color coding system, starting with a white/blue ribbon, then a white/orange ribbon, and so on. The 24th binder group has a violet/brown ribbon, completing a super binder of 600 pairs.
In cables of more than 600 pairs, each of the 600-pair super binder group bundles is wrapped wi…
Extra pairs and colors
When working on aerial cable splicing and installation, it is common to use a telephone lineman's set or "butt set" to communicate over long distances. To facilitate this, extra pairs of wires are embedded in cables using "major" colors for both wires (instead of the major/minor color combinations used for the rest). One extra pair (red-white) may be embedded into cables that are 6 to 75 pairs; two pairs (red-white and black-white) may be encapsulated in cables of 100 to 30…
