Some Telephones Are Dead (No Dial Tone or Lights)

Some Telephones Are Dead (No Dial Tone or
Lights)
Possible Cause 1:
Possible Cause 2:
The telephones are not receiving power.
What to do: Check that each telephone is plugged into a
telephone wall jack that you know is working.
• If the telephones now have dial tone and lights, there
may be a problem with the system wiring or the control
unit associated with the faulty telephone or telephones.
Call the Lucent Technologies Helpline at
1-800-628-2888 (consultation charges may apply).
• If the telephones are still dead, go to Possible Cause 2.
For single-line telephones, the Idle Line Selection may be
set incorrectly. (If not a single-line telephone, go 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 4 in System Programming ). Check to see whether
the telephone now has dial tone.
• If the telephone receives a dial tone, you have solved
the problem.
• If the telephone is still dead, go to Possible Cause 3.
