Switch group interface
The routing elements of switch groups are controlled via control inputs I3 and I4. Con-
trol is effected using external switches (door contacts, time switches, etc.). The signal
no-load voltage is approx. 40 VDC, the short-circuit current approx. 4 mA.
The permissible switch and loop resistances are as follows:
• Active state (On): < 4.5 kΩ
• Passive state (Off): > 11 kΩ
Warning
The control inputs do not require an external power supply but they must have a floating con-
nection.
There are no special requirements for the cables.
Tab. 71 Switch group control via the control inputs
Other conditions:
• The switch group configuration determines which of the switch groups are switched.
• An options card’s control inputs can control one or more switch groups.
• The same switch group can only be switched by the control inputs of one options
card.
• Control of the switch groups using the control inputs takes priority over control using
function codes.
4. 7. 6 Audio interface
The audio interface can be used for the following purposes:
• to play music or an announcement to connections with callers on hold ("Music on
hold" function).
• to play music or an announcement for the announcement service (announcement
prior to answering), voice mail greetings or for "Music on hold" and then to store it as
a wave file.
Any playback equipment (tape recorder, CD player, etc.) with a line output can be used
as the audio source.
