What is an MSN?
MSN = Multiple Subscriber Number. Up to ten different phone numbers can be applied
for to utilise the ISDN multi-device connection. An MSN is one of the phone numbers
without the area code assigned by you.
Your telephone uses the MSN according to your preferences. There are two types:
Incoming MSN: phone numbers which can be used to call you. You can assign the
◆
incoming MSN to specific internal parties (end devices). Incoming calls are only
routed to the end devices assigned the respective incoming MSN. End devices are
handsets or answering machines.
Outgoing MSN: phone numbers identified to the person called. The outgoing MSNs
◆
are used for invoicing by the network provider. Each internal party can be assigned
a fixed outgoing MSN.
Potential internal parties are:
Handsets, which can be assigned the internal phone number 11 to 16.
◆
Data modules (page 143), which can be assigned the internal phone numbers 41
◆
to 46.
The integrated answering machines (on SX150isdn), which are assigned the
◆
internal phone numbers 91 to 93.
Examples for assigning MSNs:
You have ordered four MSNs, two for business use (MSN1, MSN2) and two for private
use (MSN3, MSN4). Four handsets are connected to one base. Two handsets (Int.11 and
12) and the answering machine AM 91 are for business use, two handsets (Int.13 and
14) and the answering machine AM 92 are for private use.

The following applies to Comfort handsets S1, SL1:
Because internal 11 and internal 12 handsets are assigned two (receiving) MSNs each,
they can use the MSN next call performance feature (page 127). They can change to
(sending) MSN2 during each outgoing external call. The internal 13 and 14 handsets
cannot do this.
