3.5.2 ISDN operating mode
In contrast to the analogue POTS operating mode, in the ISDN operating
mode two independent telephone hybrids are available.
A handset or a headset can be connected for Pre Talk. Using an analogue tel-
ephone is not possible in this operating mode.
FIG. 6 MINIMUM WIRING IN ISDN OPERATING MODE
The maximum wiring with all options is shown in Fig. 7. Instead of the oper-
ation via the front keypad, the system can also be operated with the use of a
PC with MAGIC TH2 Software or a MAGIC TH2 Keypad connected to the
RS232 interface.

be used because otherwise the contacts in the socket will be destroyed.
