Installation
Tab. 74 LED on the EFOP fan-out-panel
8 LEDs (2 x LED 1...4)
All LEDs lit
Individual LEDs off
All LEDs off
Notes:
– The EFOP fan-out-panel is reset from emergency operation to normal
operation with a delay of 3 minutes. This allows the communication
server to reboot after a power failure. The delay also applies to individ-
ual FXS lines.
– If individual FXS lines are in emergency operation, the corresponding
analogue exchange line from the communication server can no longer
be used. Unexpected faulty switching may occur if an active call was
being made on the FXS line and the exchange line prior to the emer-
gency operation.
– In emergency operation the emergency phone is connected directly
with the analogue exchange line so no exchange access prefix has to
be dialled.
