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.

The control inputs of ODAB cards can also be used to control switch groups (see "Equipment

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 con-
nected general bell (or total impedance in the case of several devices connected in
parallel) must not fall below 1 kΩ. The ringing voltage is 48 VAC. A 48 V relay must be
interposed when connecting a large number of auxiliary bells.
