■ If the Ringing Options setting is No Ring or Delay Ring, change the setting
to Immediate if appropriate. From another extension, dial the extension
where the problem is. If the phone now rings, you have solved the problem.
If not, go to Possible Cause 5.
■ If the Ringing Options setting is Immediate, go to Possible Cause 5.
Possible Cause 5: 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, then replace it with the original
telephone and check again. If the original telephone still does not ring, 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, there may be a problem with
the system wiring or the control unit. To test one wiring possibility, go to
Possible Cause 6.
NOTE:
The following procedure may help Lucent Technologies Helpline
technicians analyze your problem. However, you should not perform this
procedure unless you have experience removing the control unit cover and
working with control unit extension jacks. Before proceeding, consult
system planning Form 2a, System Numbering: Extension Jacks.
CAUTION:
!
If you must check something on the control unit, proceed with caution. Avoid
standing on a box or chair to reach the unit if it is installed out of easy reach.
If you do not have a stable ladder or other proper equipment, do not
proceed; wait for the Lucent Technologies technician.
Possible Cause 6: The wiring is faulty somewhere in the system.
What to do: Test the control unit module and jack where the telephone is
plugged in.
■ Identify the port where the nonfunctional telephone is connected. Identify a
second port in the same module connected to a functional telephone and
unplug the jack from the module. Plug the jack for the non-working phone
into the extension jack that is now open. If the telephone works, call the
Lucent Technologies Helpline at 1 800 628-2888 (consultation charges
may apply).
