Pair Identification Colours
For pairs numbering 1 through 25, the pair identification colours are outlined below. In cable constructions containing more than 25 pairs, the colours are repeated as necessary. Colour coded binders are used to identify 25 pair groups of colour coded pairs.

Identification of Groups of Pairs
For cables through 600 pairs, 25 pair groups are identified by their binder colours in the same sequence as the pair identification is accomplished. Group 1 has White-Blue binders. Group 2 has White-Orange binders, etc. In this manner, each pair is uniquely identified. In cables having 25 pairs or less, binders are normally not used. However, if specified, the binders will be Group 1, White-Blue. For cables of 100 pairs or less, the use of the White binder is optional.

Super-units Binder Identification Colours
It is desirable for manufacturing purposes to combine four 25 pair groups into “super units” when cables have 900 pairs or more.

Standard Telephone Cable
Various arrangements of pairs, units, groups, and super units are possible for standard non-screened telephone cables both filled and aircore.
The following constructions illustrate the lay-ups normally provided. Cables containing 1200 pairs or more are also available with mirror image core constructions as shown.
