The control inputs of ODAB cards can also be used to control switch
groups (see "Equipment on the ODAB options card", page 138).
FXS mode: General bell
One FXS interface per communication server can be configured for the connection
of a general bell. It is possible to use commercial auxiliary bells designed for con-
nection in parallel to analogue terminals as a general bell. However the impedance
of the connected general bell (or total impedance in the case of several devices
connected in parallel) must not fall below 1 k. The ringing voltage is 48 VAC. A 48
V relay must be interposed when connecting a large number of auxiliary bells.

4. 7. 4 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.
