channel of the two available B channels is used. If there is a call on the
second channel, the system signalises ’Line busy’. Only the
Audio1/AES IN/OUT interfaces (see Fig. 6 and Fig. 7) are used.
–

: The system is connected to the ISDN and two independent hy-
brids are available.

operating mode only one channel is available in general. Only the

the auto answer can
be activated. Under the option
Current Audio Line

,
HOLD
or
ON AIR
you can set which Audio line is activated automatically after the
call has been accepted.
• It is possible to activate a ring tone as audible signal for incoming calls via
the function

incoming calls
can be signalised via the Pre Talk Audio line if a telephone handset or
headset is connected.

is activated, a disturbing 50 Hz humming is fil-
tered out. The spurious signal is injected via the POTS connection in the
system.The reason is in the majority of cases an incorrect cabling of the pri-
vate branch extension.

it is possible to insert a pause be-
fore redialling - directly after disconnection - in a range of
0 ... 7
seconds.
