Connecting the base to a PABX
Selecting dialling mode/
options (ISDN)
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 base to an ISDN
PABX or exchange (e.g., Centrex) that is con-
trolled using keypad protocol. The digits/
characters 0–9, * and # are sent as keypad
information elements. Please ask your serv-
ice 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.
Auto. 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
during dialling as commands to the
exchange or PABX.
Regardless of the setting options above,
after dialling or during a call the phone
switches automatically to tone dialling
(DTMF), e.g., for remote control of an
answering machine.
