8 Private Branch Exchange / Value Added Services
The % button on the handset is used in private branch exchanges and for taking
advantage of supplementary services offered by your telephone network provider.
8.1 R button on private branch exchanges
If the telephone is connected to a private branch exchange, all the functions associated
with the
% button, such as transferring calls, automatic call back, etc., can be used. A
private branch exchange requires a Flash time of 100 ms (refer to Chapter 10.2). The
dealer where you purchased the exchange can provide information as to whether the
telephone will work properly with the exchange.
8.2 R button and supplementary services offered by your telephone
network provider
Your SWITEL telephone supports the most important supplementary services offered by
your telephone network provider (e.g. brokering, call waiting, three-way conferencing, etc.).
To use the supplementary services offered by your telephone network provider, set the
Flash time to 300 ms (refer to Chapter 10.2). Please contact your telephone network
provider with regard to enabling the supplementary services.
8.3 Entering a dialling pause
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 possible 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.
After entering the number for the outside line and before continuing with the actual phone
number, press the
(
button for approx. 3 seconds.
P
appears in the display. After
dialling the number for the outside line, the telephone then waits a defined time before
dialling the actual phone number. The
(
button can be assigned one of four different
dialling pauses (refer to Chapter 10.3).
Note: The pause can also be entered with the phone numbers in the phone book.
