Operating Modes
6 OPERATING MODES
The MAGIC ISDN Telephone Hybrid system has a very flexible implementa-
tion. Therefore, nearly all kinds of applications can be realised. In the follow-
ing, the different operating modes/possibilities are displayed. Of course, the
displayed operating modes can be mixed. Further possibilities can be found
in the description of the software functionalities.
6.1 Default operating mode
In this operating mode, the system is used with its basic functions:
– Operation only via the local Touch screen (e.g. for a presenter who uses all
functions on his own)
– Use of at least two Audio interfaces for Pre Talk and On Air.
– The Pre Talk can be done via the Pre Talk Audio interfaces or via the op-
tional handset.
6.1.1 ... without AES/EBU/ANALOGUE module
FIG. 13 DEFAULT OPERATION WITHOUT AES/EBU/ANALOGUE MODULE
Without the AES/EBU/Analogue module (see Fig. 13) at least two systems are
necessary, to ensure that two Audio interfaces are available. Additionally, up
to four ISDN S
0
lines for 8 callers are available.
By installing further MAGIC ISDN Telephone Hybrid Slave systems as well as
AES/EBU/Analogue Modules, the system can be upgraded according to re-
quirements.
6.1.2 ... with the AES/EBU/ANALOGUE module
When using the AES/EBU/Analogue Module (see Fig. 14) one system is enough
for the Pre Talk and On Air functionality with two ISDN S
0
lines for four call-
ers. The free Audio interface can be used, e.g. for a separate Hold signal.
By installing further MAGIC ISDN Telephone Hybrid Slave system(s) as well as
AES/EBU/Analogue Modules, the system can be upgraded according to re-
On Air mixing signal of all
