Until a few years ago, it was customary to use "quad" The color combinations are applied to the insulation that covers each conductor. Those pairs are then combined in to bundles of 25 pairs per bundle, so a 200 pair cable has 8 binder groups. Most telephone wire are one or more twisted pairs of copper wire.
