    When cables of larger than 25 pairs are required, the core shall be assembled into 25-pair sub-units, each colour coded in accordance with ICEA publication S-80-576. Cables with over 600 pairs shall have 25-pair binder groups combined into super units. These super units shall be wrapped with a solid colour thread that follows the primary colour scheme of white, red, black, yellow and violet. Binder colour code integrity shall be maintained wherever cables are spliced.
