6.2.2 MSN Configuration
In this menu, you can assign the available ISDN numbers to the required services (e.g.
PPP routing, ISDN login).
If you use the ISDN interface for outgoing and incoming dialup connections, your own num-
bers for this interface can be entered in this menu (these settings are not possible for
leased lines). Your device distributes the incoming calls to the internal services according
to the settings in this menu. Your own number is included as the calling party number for
outgoing calls.
The device supports the following services:
• PPP (routing): The PPP (routing) service is your device's general routing service. This
enables ISDN remote terminals to establish data connections with your LAN, among oth-
er things. This enables partners outside your own local network to access hosts within
your LAN. It is also possible to establish outgoing data connections to ISDN remote ter-
minals.
• ISDN Login: The ISDN login service enables both incoming data connections with access
to the SNMP shell of your device, and outgoing data connections to other bintec devices.
As a result, your device can be remotely configured and administrated.
• IPSec: bintec devices support the DynDNS service to enable hosts without fixed IP ad-
dresses to obtain a secure connection over the Internet. With the IPSec Callback function
and using a direct ISDN call to an IPSec peer with a dynamic IP address you can signal
to this IPSec peer that you are online and waiting for the setup of an IPSec tunnel over
the Internet. If the called peer currently has no connection to the Internet, the ISDN call
causes a connection to be set up. The identification of the caller from his or her ISDN
number is enough information to initiate setting up a tunnel.
• X.25 PAD: X.25 PAD is used to provide a protocol converter, which converts non-
packet-oriented protocols to packet-oriented communication protocols and vice versa.
Data terminal equipment sending or receiving data on a non-data-packet-oriented basis
can this be adapted in line with Datex-P (public data packet network based on the prin-
ciple of a packet switching exchange).
When a call comes in, your device first uses the entries in this menu to check the type of
call (data or voice call) and the called party number, whereby only part of the called party
number reaches the device, which is forwarded from the local exchange or, if available, the
PBX. The call is then assigned to the corresponding service.
