IP addresses 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.
Note
If no entry is specified (ex works state), every incoming ISDN call is accepted by the
ISDN Login service. To avoid this, you should make the necessary entries here. As
soon as an entry exists, the incoming calls not assigned to any entry are forwarded to
the CAPI service.
