Philips Fax Machine Manual page 13

Your fax machine is not an ISDN fax (group 4), but an analogue fax
machine (group 3). Therefore it cannot be used directly on an ISDN
connection. You will need an (analogue) adapter or an ISDN connection
for analogue devices. For further information please refer to your ISDN
instructions.
Private branch exchange systems are very common in large
companies. ISDN connections are private branch exchanges and
are used very often in private households. To get a connection
from a private branch exchange to the public network you have
to dial a key to obtain the outside line.
Please note: An additional telephone which is connected to a normal
telephone line together with your fax machine must not be mixed
up with a private branch exchange.
If you wish to use your fax machine on a PABX you have to change some
settings in function 15.
In function 15 you can select either tone and pulse dialling and
then if there is a connection to a private branch exchange.
Your phone can dial in two different ways. Older telephone systems
usually work with pulse dialling whilst modern, digital systems use
tone dialling, which is faster. You can change the dialling mode of your
fax machine. If you do not know which method your line uses, contact
your telephone company.
It is necessary to send tone dial signals to make use of certain services. If
your telephone system works on pulse dialling, you can still send tone
signals by pressing * or #. All numbers are then transmitted
in the tone dialling method. As soon as you replace the handset
on the fax machine, your fax machine will switch back to pulse
dialling.
If you cannot establish the desired telephone or fax
connection to the called party, select a different
dialling mode.
Select function 15 by pressing FUNCTION and then entering
the digits 15. Press OK.
Choose pulse or tone dialling by pressing </>. Press OK.
Press </> in order to switch to operation on a PABX extension.
Press OK.
Now enter the key that has to be pressed to obtain an outside line
(outside line access code). This is either R or a number key. Press
OK.
Press OK. Your machine will then check that the outside line can
be obtained.

You will be asked to repeat the entry. Change either the dial mode
or check the key for obtaining an outside line. However, if you have
chosen the correct dial mode as well as the correct key and on the
display still appears the message
delete the key for obtaining the outside line by pressing <.
In case your PABX requires R to obtain an outside line but it is
still not possible to get through to the line, your system might not
be according to the regulations. Therefore some technical settings
have to be changed on your fax machine. Please refer to
your "Fax Call Centre".
