If the green light is on at all QCCs in the system, then Night Service is turned on. Press the button to deactivate the feature and to turn the light off. Finally, check to see whether incoming calls ring at the console. If they do, you have solved the problem. If not, go to Possible Cause 5.

If the green light is off, then Night Service is not turned on; go to Possible Cause 5.

Possible Cause 5: The telephone may be defective.

What to do: Test the telephone by replacing it with another MLX-20L telephone that you know is working properly.

If only one MLX-20L is available, plug that telephone into a jack that you know is working and then retest. If the telephone rings for incoming calls, then the original jack may be faulty; call the Lucent Technologies Helpline at 1 800 628-2888 (consultation charges may apply). If the telephone still does not ring, there may be a problem with the system wiring or the control unit; call the Lucent Technologies Helpline at 1 800 628-2888.

If the replacement telephone rings for incoming calls, then replace it with the original telephone and check again. If the original telephone still does not ring for incoming calls, then the original telephone may be defective. Call the Lucent Technologies Helpline at 1 800 628-2888 (consultation charges may apply).

If the replacement telephone does not ring for incoming calls, there may be a problem with the system wiring or the control unit. Call the Lucent Technologies Helpline at 1 800 628-2888 (consultation charges may apply).
