4.7.3.3.1.6 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 connection 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 kW. The ringing voltage is 48 VAC. A 48 V
relay must be interposed when connecting a large number of auxiliary bells.

4.7.4 Fan-out panel FOP
The interface cards 8DSI have four-fold assigned RJ45 sockets. With the fan-out panel FOP a total of 10
four-fold assigned RJ45 sockets can be split to individual RJ45 sockets.
The fan-out panel (FOP) takes up the space of one height unit in a rack and can be fitted directly above or
below the communication server.
