Emergency fan-out-panel (EFOP)
1)
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 a power failure the EFOP switches ex-
change lines automatically and directly over to up to 8 analogue phones.
The EFOP fan-out-panel also monitors the voltage of the FXS lines to the communi-
cation server. If for example ports are switched off due to overloading, the corre-
sponding exchange lines switch over automatically and directly to the analogue
phones.

In the following, these analogue phones are referred to as emergency phones. In
normal operation emergency phones act like ordinary internal phones. Only
phones capable of operating without their own power supply are suitable as emer-
gency phones. Both DTMF and pulse dialling phones are supported. It is recom-
mended to identify emergency phones as such.
The fan-out panel EFOP takes up the space of one height unit in a rack and can be
fitted directly above or below the communication server.
