Three-Pair and Four-Pair Modularity

Figure 5-8 shows 3-pair and 4-pair modularity from the port circuit pack to the terminal pins at the information outlet (modular jack). Most terminals connect to an information outlet installed at the work location.

Make the connections from the port circuit pack to the modular jacks. Then, plug the terminal into the modular jack.
