Troubleshooting the System
Some Phones Are Dead (No Dial Tone or Lights)
What to do: Test the outlet by plugging in an appliance that you know is working,
for example, a lamp or radio.
If the appliance does not work, the outlet is faulty. If possible, plug the
control unit into a different outlet. Check the circuit breaker or call an
electrician.
If the appliance works, the wiring may be faulty elsewhere in the system.
Call the Lucent Technologies Helpline at 1 800 628-2888 (consultation
charges may apply).
Some Phones Are Dead
(No Dial Tone or Lights)
Possible Cause 1: The telephones are not receiving power.
What to do: Check that each telephone is plugged into a telephone wall jack
known to be working.
If the phones now have dial tone and lights, there may be a problem with
the system wiring or the control unit associated with the faulty phone(s).
Call the Lucent Technologies Helpline at 1 800 628-2888 (consultation
charges may apply).
If the phones are still dead, go to Possible Cause 2.
Possible Cause 2: For single-line telephones, the Idle Line Selection may be set
incorrectly. (If not a single-line telephone, skip to Possible Cause 4.)
What to do: Use centralized telephone programming to ensure that the
Ringing/Idle Line Preference is set to On (see Chapter 5 in System
Programming ). Check to see whether the phone now has dial tone.
If the phone receives dial tone, you have solved the problem.
If the phone is still dead, go to Possible Cause 3.
Possible Cause 3: For single-line telephones, the Auto Line Selection may be set
incorrectly; see Chapter 5 in System Programming . (If not a single-line telephone,
skip to Possible Cause 4.)
What to do: Use centralized telephone programming to set the Auto Line
Selection for the extension. Check to see whether the phone now has dial tone.
If the phone receives dial tone, you have solved the problem.
If the phone is still dead, go to Possible Cause 5.
