Prefix Number
• Under
Length of Internal Telephone Numbers
you indicate the length of
your internal telephone numbers. In this way, the prefix number is dialled
automatically, if the length of the entered calling number exceeds the
Length of Internal Telephone Numbers
you indicated here. If you do not
want to use this functionality, or if you use the system with a main connec-
tion, please enter a
0
into the respective field.
Examples: Length of internal telephone numbers: 3
Calling number entered: 130
It is dialled: 130
Length of internal calling numbers: 3
Calling number entered: 5271130
It is dialled:
0 5271130
• Under
External Prefix Number
you enter the external prefix number
which you must dial to get an outside line. In most cases it is
0
.
• Some PABXs transmit the calling number with prefix number to the sys-
tem. If you want to transfer the displayed calling number without the pre-
fix number directly into the telephone book, you can enable the function
Skip prefix number on incoming call .
MSN (Multiple Subscriber Number
Usually the entry of a MSN is not necessary. However, if several systems are
operated with one ISDN interface, you can allocate a certain calling number
to a certain system by entering a MSN.
Example: A telephone, an ISDN PC card and a MAGIC DC7/AC1 system unit
are operated with one ISDN interface. From your provider you got the follow-
ing MSN: 5271011, 5271012, 5271013.
Without a MSN entry, all three units respond to the incoming call - no matter
which of the three calling numbers was dialled. However, if a different MSN
is allocated to each unit, the system only responds if exactly this MSN was di-
alled by the caller. If you enter e.g. the MSN ’5271013’ for the
MAGIC
DC7/AC1 system , the system will only signal the call, if the caller dialled
’5271013’. However, precondition for this example is that you enter the same
MSN for
MSN 1
and
MSN 2
.
NOTE
The following settings are only necessary, if the system is operated with a
PABX.
In the
ISDN Leased Line Mode, these settings are not available.
TIP
To skip the automatic prefix number temporarily, you can place a „
-
“ in front
of the calling number (e.g. „-130“)
ATTENTION You must enter the external prefix number at any case if you operate the sys-
tem with a PABX since only in this case the system waits for a dial tone. With-
out an external prefix number, the calling number is transmitted too fast and
the connection cannot be established.
NOTE
A MSN can only be entered if the ISDN operating mode has been selected.
