Explanation
A 110-block is a punch-down style termination block used on patch panels. If cables were improperly terminated or not seated correctly, individual wire pairs may not make proper electrical contact. A punch down tool physically seats each wire conductor into the 110-block's insulation displacement connectors (IDC) to ensure a solid connection - resolving bad terminations. A cable certifier then verifies that the terminated cables meet performance standards (e.g., Cat5e or Cat6 specs) by testing for continuity, attenuation, crosstalk, and other metrics - confirming the fix. A crimper is used for attaching RJ-45 connectors to cable ends, not for 110-block terminations. A toner probe locates cables but does not fix terminations. The ping command is a software tool that cannot diagnose physical layer problems like a missing link light.
