To access the ports, use a 180-degree male RJ-21 connector with a shielded PVC trunk cable and secure
to a maximum of 4 in-lbs of torque. You can access the ports in one of the following ways:
• Through a patch panel by terminating the cable and shield with an RJ-21 connector.
• Directly by using a cable that is terminated with 12 RJ-45 connectors.
The RJ-21 connector is shown in Figure 125.
