A compact multifunction 5-terminal type compatible telephone line tester has batteries fitted in its frontal access shaft that fits into a to be tested connector between tightly arrayed protectors assembled in a cross connect box. A light powered by the battery is integrated at the tester front face in between the connection pins. The protector removed from the to be tested connector may be inserted in a terminal that laterally extends from the tester. An electric circuit tests and indicates the protector condition and switches the light on upon manual pushing of a switch. The electric circuitry is powered by the batteries. A mechanical switch is actuated by the protector housing while the protector is connected to the terminal for automated protector through connection to the to be tested connector. Lateral terminals and a jack connector on the back side provide access to the connector. |
