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 nonbusiness 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.
!
CAUTION:
The power cord should hang straight down from the connector, flush against
the plastic case for the entire length of the board. Do not install the power
cord at an angle to the case or with a loop in it.
■ 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 (see page 6-1).
■ 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
(see page 6-1).
