XVI.2. CABLES
Using standard telephone installation cable binders may be useful for providing compliance
with color code standards.
Cable binders that are generally used contain 50, 100 or 200 pairs. Although alternative
kinds of cables are available in the market, they should not be used except for very special
cases.
There are 5 prime colors in the color code that is referred. These are BLUE, ORANGE,
GREEN, BROWN and GRAY, respectively. Alongside these, there are also auxiliary colors.
Those are WHITE, RED, BLACK and YELLOW. Cables are also produced in colors that do
not comply with standards.
There are two kinds of arrangement in the color code, based on the five prime colors.
The arrangements are done in groups of 10 pairs in general.
Type 1 cable arrangement

The 50-pair cable binder has been arranged in 5 groups. Each group consists of 10 pairs.
Besides, nylon stripes that are in prime colors are available in order to differentiate the
groups. Those stripes have been wrapped around each group separately. The 10-pair
groups have been arranged within themselves according to Type 1 or 2. The 50-pair cable
binder is mounted by taking into consideration the standard arrangement regarding the stripe
colors.
