Troubleshooting the System
Some Telephones Are Dead (No Dial Tone or Lights)
Possible Cause 3: For single-line telephones, the Auto Line Selection may be
set incorrectly; see Chapter 4 in System Programming. (If
not a single-line telephone, go 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 telephone now has a dial tone.
• If the telephone receives a dial tone, you have solved
the problem.
• If the telephone is still dead, go to Possible Cause 5.
NOTE:
The following procedure may help Lucent Technologies
Helpline technicians analyze your problem. You should not
perform this procedure, however, unless you have
experience removing the control unit cover and working with
the control unit extension jacks. Before proceeding, consult
System Planning Form 2a, System Numbering: Extension
Jacks.
!
WARNING:
If you must check something on the control unit,
proceed with caution. Do not stand 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.
