Menu: Entry of MSN/DDI for external S0 ports
In this menu you enter the corresponding MSNs for each external S0 connection. In
case of a multipoint interface, you are provided with up to 10 phone numbers (MSNs)
for each S0 connection. For a point-to-point connection, you have a basic number to
which extension numbers (DDIs) are added. Enter the requested DDI. One MSN/DDI
must not be assigned to several external ports. Furthermore you can assign a name
to each number. This name will be displayed in the "From/For Display", which is avai-
lable with system phones and internal voicemail systems.
Example:
Caller John (name taken from phone book) calls subscriber 50 via external MSN
4280. The telephone displays the name "John" in the first line while in the second line
"Call for MSN 1" (MSN 1 = 50) is being displayed. If you e.g. assigned the name "Pri-
vate" to MSN 4280, the telephone will display the name "Private" instead of "Call for
MSN 1".
Note:
External and internal numbers may be identical.
With this telephone system DDIs must not be identical with internal ex-
tension numbers. You can, however programme them this way.
In case you also received the DDI "0" from your provider, you must as-
sign this DDI to an extension by all means. This can of course also be
the extension which has been defined as switchboard
Menu: Call forwarding external
Call forwarding can be set up for each MSN at a multipoint interface. The "number for
call forwarding" item informs you how many MSNs have call forwarding enabled. In
order to modify the call forwarding, select the desired MSN and enter the desired da-
ta in the lower entry fields. Should several external S0-ports be used, individual set-
tings are possible for each S0. If the call forwarding is reprogrammed via a parallel-
connected terminal unit, the settings of the telephone system will also be changed
accordingly, provided that the CFI ISDN feature is available. If the CFI feature is not
available, the reprogrammed parameters will automatically be reset within the tele-
phone system after a short delay (depending on the exchange office).
You can choose among the following settings:
•
Call Forwarding Unconditional (CFU)
•
Call Forwarding On Busy (CFB)
•
Call Forwarding No Reply (CFNR)
