The110 terminal block is used for data cables because they are rated for Category 5e and higher. The 110 Block in the ACT panel is capable of terminating up to 25 pairs on each row, 50 pairs all together. Unlike 66 Blocks, which pass the signal from left to right, 110 Blocks pass the signal from bottom to top. You punch down wire pairs between the plastic teeth on the block, and then attach a connecting block with metal contacts on top of them. Punch down a second set of wires on the connecting block, and the continuity is complete. As with 66 Blocks, you punch down on 110 Blocks in pair order, Tips first. Cables enter the block from the center channel and are terminated above and below. Cables 1, 2, and 3 enter from the left and terminate at the top row. Cables 4, 5, and 6 enter from the right and also terminate at the top. Cables 7, 8, and 9 enter from the left and terminate on the bottom row. Cables 10, 11, and 12 enter from the right and also go down.
