Return to Task List
Figure 198, 3-Pair and 4-Pair Modularity,
on page 514 is from the port circuit pack to the voice or data
terminal. Refer to
Install Telecommunications Cabling
on page 403 for descriptions of 3- and 4-pair
modularity and distribution.
Most terminals connect to an information outlet (modular jack) installed at the work location. Make the
connections from the port circuit pack to the modular jacks, as shown in
Figure 198, 3-Pair and 4-Pair
Modularity,
on page 514. Then, plug the terminal into the modular jack.
