Emergency fan-out-panel (EFOP)

To be able to make emergency calls even in the event of a mains power failure, you
have the possibility of running up to 8 analogue FXO exchange lines via the EFOP
(emergency fan-out-panel). In the event of power failure, the EFOP automatically and
directly switches over exchange lines to up to 8 analogue phones.
The EFOP fan-out-panel also monitors the voltage of the FXS lines to the communica-
tion server. If for example ports are switched off due to overloading, the corresponding
exchange lines switch over automatically and directly to the analogue phones.
