Connecting the desktop phone to a PABX
Selecting dialling mode/
options
The keypad function allows you to control
certain features by entering sequences of
characters and digits.
The keypad function must be activated
when you connect your desktop phone to
an ISDN PABX or exchange (e.g., Centrex)
that is controlled using keypad protocol. The
digits/characters 0–9, * and # are sent as key-
pad information elements. Please ask your
service provider about the information and
codes you can transmit.
Setting options
You can switch between the Auto. Tone Dial,
Auto. Keypad and Dial of * and # settings.
Auto. Tone Dial
Once normal dialling has been activated,
* and # are not transmitted during dial-
ling and if * and # are entered it is not pos-
sible to switch to the keypad.

Once * or # have been entered, this set-
ting automatically switches signalling
during dialling to the keypad. This auto-
matic switchover is needed for giving
commands to the exchange or PABX.
Dial of * and #
Once Dial of * and # has been activated,
the * and # characters are transmitted

Regardless of the setting options above,
