DLC Console Not
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.

a problem with the system wiring or the control unit. Call the Lucent
Technologies Helpline at 1 800 628-2888 (consultation charges may
