private branch exchange requires a Flash time of 100 ms.
The dealer where you purchased the exchange can provide

Dialling paus
e
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.
Press the
F
button once between dialling the number for
the outside line and the actual phone number.
After dialling
the number for the outside line, the telephone waits 3
seconds before dialling the actual phone number.
