WAN-Miniport driver 32
Shorthold Time
The ‘Shorthold Time’ option allows you to specify after how long the ISDN connection is
broken if no data is transmitted. Shorthold time = 0 means that the computer will not break
a connection itself but will accept shorthold requests from the remote side.
Callback Prefix
The ‘Callback Prefix’ is used to insert one or more numbers in front of the callback numbers
for all clients. This might be required in the following situations:
• The server is operated behind a PBX, which requires a 0 for connection. The 0 may
be automatically included in the callback prefix when dialing.
• The Euro-ISDN protocol suppresses the leading zero when sending. Therefore, the
server will normally not be able to call the client back in shorthold mode. However, with
the callback prefix ‘0’, the complete call number is dialed.
Authentication Features
Select the ‘Authentication Features’ page if the Security Dynamics security system has
been integrated in the network, and you wish to configure the Security Dynamics
Authentication in the WAN-Miniport driver. For the basic functions of the Security
Dynamics Authentication see Using Security Dynamics Authentication
on page 76.
Authentication Protocol
Select here whether the WAN-Miniport driver runs the normal RAS authentication (‘None
(RAS Authentication Only)’) or the Security Dynamics Authentication with incoming calls.
The following parameters can be configured for Security Dynamics Authentication:
