Private Branch Exchanges
5.1
R button on private branch exchanges
If the telephone is connected to a private branch exchange
(PABX), functions such as transferring calls and automatic
call back etc. can be used.
The "R" signal button enables access to these functions.
Please contact your sales outlet where the PABX was
purchased to find out whether your phone can operate
properly in the private branch exchange and if other facilities
and services are available.
5.2
Dialling phone numbers when operating in
a PABX
In the case of private branch exchanges, it is necessary to
dial a specific number (e.g. “9” or “0”) in order to obtain the
dialling tone for an outside line. When using some older
private branch exchanges, it takes a little time before the
dialling tone becomes audible. Particularly in the case of
such private branch exchanges, it is useful to insert an
automatic pause after the number for the outside line so that
the number can be dialled in a continuous process without
having to wait for the dialling tone.
To insert a dialling pause, press the Redial button once after
entering the number for the outside line and before entering
the actual telephone number. After dialling the number for
the outside line, the telephone then waits 3 seconds before
dialling the actual phone number.
