Setting up/deleting an ISDN phone number (MSN)
Your ISDN connection offers you two telephone lines (B channels) that you can use at
the same time. You can establish up to ten separate phone numbers (MSN) on your base
station.
What is an MSN?
MSN = Multiple Subscriber Number. You can apply for up to ten different telephone
numbers for one multiple ISDN connection. An MSN is one of the phone numbers
assigned to you
without an area code
.
You telephone uses the MSN entirely as you require. The following differentiation is
made:
◆
Receive MSN:
Phone numbers you may be called on. You can assign the receive
MSNs to specific internal users (terminals). Incoming calls are only forwarded to the
terminals to which the relevant MSN has been assigned. Terminals are, for instance,
handsets or answering machines.
◆
Send MSN:
Phone numbers that are identified to the person you are calling. The
network operator calculates charges based on the send MSNs. You can assign a fixed
send MSN to each internal user.
Possible internal users are:
Depending on the functions provided by the base, you can assign internal phone num-
bers to the following internal users. Please refer to the operating instructions for the
