System Problems
6-31
What to do:
Call your local phone company and find out whether they send a hold
release signal. If the local phone company does not send a hold release signal, or
if they do but the problem still occurs, call the hotline.
All Calls Disconnected
Possible Cause 1:
You just ran the Restore Programming (#125) procedure.
What to do:
This is normal behavior after running Restore Programming (#125);
the system resets itself. In the future, warn users before beginning the restore, or
perform the restore during non-business hours. If you did not run Restore
Programming (#125), go to Possible Cause 2.
Possible Cause 2:
Power was interrupted to the control unit.
What to do:
Make sure the control unit’s power cord is plugged securely into the
wall outlet. Also make sure the on/off switch is in the “ON” position (“O”) if you
have a 5-Slot carrier.
■ If the green LEDs on the modules are lit and the trouble is gone, the
problem is corrected.
■ If the green LEDs on the modules are lit but the trouble remains, call the
hotline.
■ If the green LEDs on the modules are out, go to Possible Cause 2 in “All
Phones Dead: No Dial Tone or Lights.”
■ If any green LEDs on the modules are flashing, call the hotline.
