25 pair termination on a 66 Block
25 pair cabling can be broken down into 5 Primary color groups:
White, Red, Black, Yellow, and Violet Each of these Primary groups has 5 colored pairs (10 individual wires), consisting of the Primary color, plus a Secondary color of: Blue, Orange, Green, Brown, or Slate. In example: White Blue / Blue White White Orange / Orange White White Green / Green White White Brown / Brown White White Slate / Slate White Red Blue / Blue Red Red Orange / Orange Red Red Green / Green Red Red Brown / Brown Red etc... Start at the top of the 66 block, and work your way down the side with the Primary Colored wire always being above the Secondary Colored wire. So in other words, White Blue, then Blue White. In Red it would be Red Blue then Blue Red, etc... |
