Switch group control via the control inputs
Other conditions:
• The same control inputs can control one or more switch groups.
• The same switch group can only be switched by the 2 assigned control inputs.
• Control of the switch groups using the control inputs takes priority over control using
function codes.
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 con-
nected general bell (or total impedance in the case of several devices connected in
parallel) must not fall below 1 k
Ω
. The ringing voltage is 48 VAC. A 48 V relay must be
interposed when connecting a large number of auxiliary bells.

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 sock-
ets.
The fan-out panel (FOP) takes up the space of one height unit in a rack and can be fit-
ted directly above or below the communication server.
