4. First you are asked whether your ISDN line is a PBX exten-
sion. If your computer’s ISDN adapter is connected direct-
ly to the ISDN BRI, make sure the “Private Branch Ex-
change (PBX)” option is not checked. If your ISDN adapter
is connected to a PBX extension, but the extension is set
for automatic outside line access (i.e., without an outside
line prefix), then you should also make sure this option is
not checked.
5. If your line is a PBX extension that requires a prefix for
outside dialing, check the “Private Branch Exchange”
option. This activates the additional options below.
Outside Line Access
Enter your outside dialing prefix (the digit you must dial to
obtain an outside line, usually “0”).
Minimum length of external numbers
Enter the minimum number of digits that external num-
bers have. For example, if extension numbers in your PBX
have three digits, enter “4”.
The FRITZ! modules use this entry to determine whether
the numbers you dial are extensions within your PBX or
outside calls, and add the outside dialing prefix where
appropriate.
For most ISDN PBX systems you can simply confirm the
default settings, “0” for the “Outside Line Access” and
“4” for “Minimum length of external numbers”.

parameters for FRITZ!fax.
Fax Number (MSN)

line to be used to send and receive faxes on your PC.
Station Code
The station code is the number that appears on the dis-

you send a fax. Usually this should be the number at
which you would like to receive faxes, i.e. the same num-
