	DLC Console Not	8
	Ringing for Incoming Calls	8

Possible Cause 1: The Do Not Disturb feature is turned on.

What to do: Check the green light next to the programmed Do Not Disturb button to see whether Do Not Disturb is turned on.

■If the green light is on, then Do Not Disturb is turned on. Press the button to deactivate the feature and to turn the light off. Finally, check whether incoming calls ring at the console. If they do, you have solved the problem. If not, go to Possible Cause 2.

■If the green light is not on, then Do Not Disturb is not turned on; go to Possible Cause 2.

Possible Cause 2: The Ringing Options Ring Timing feature for the extension is programmed for No Ring or Delayed Ring.

What to do: Use centralized telephone programming to check the Ringing

Options setting for the extension and each line (see Chapter 5 in System

Programming).

■If the Ringing Options setting for one or more lines is No Ring or Delay Ring, change the setting to Immediate, if appropriate. 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 3.

■If the Ringing Options setting is Immediate, go to Possible Cause 3.

Possible Cause 3: The telephone may be defective.

What to do: Test the telephone by replacing it with a similar telephone that you know is working properly.

■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).
