cept the calls automatically.

is accepted by the system. Via the scroll bar

matically as soon as the connection is established.

The following settings are only available in the
Line Mode POTS
:
• If you activated the
POTS 50 Hz Filter
, a disturbing 50 Hz humming is fil-
tered out. The disturbing signal is fed into the system via the POTS line.
The reason is mostly a wrong cabling of the PABX.
• An
Expander
turns down the caller signal automatically, if its level falls
below a certain threshold value. The aim is to completely filter out back-
ground noises of callers who are not currently speaking. The
Expander
is
activated by checking the respective box. With the scroll bar
Threshold
you can adjust the threshold for the Expander within the range of
-40
...
-
20 dBu
. The default setting is
-30 dBu
.
• Via the scroll bar
Redial Delay after Disconnect
you can adjust the redi-
alling delay after a connection has been dropped since the POTS telephone
line is not immediately ready for redialling. This function is possibly nec-
essary when the dialling function via a TTL contact is used (see CHAPTER
5.7.2.3.4, page 78).
