S YSTEM R EQUIREMENTS
When providing user level security for the CyberSWITCH, you must establish Remote User-to-
LAN Connectivity (like terminal servers). You may not establish LAN-to-LAN Connectivity as
routers usually do.
There are two different ways of establishing Remote User-to-LAN Connectivity:
•
through IP Routing
• through Bridging
IP Routing connectivity refers to the connectivity between the CyberSWITCH and a remote device
that can transfer IP datagrams over ISDN without MAC headers (such as an IP/PPP host device).
Bridging connectivity refers to the connectivity between the CyberSWITCH and a remote user
(computer) that is connected to the system through the ISDN bridge device. The remote computer
and the ISDN bridge may be implemented as one device like the Bridge/PPP device or the
WaveRunner in the Combinet emulation mode.
You must configure your CyberSWITCH keeping these stipulations in mind. Once your system is
properly configured, and your authentication server is properly configured, you may access user
level security by performing the following:
•
making the appropriate Telnet connection
• responding correctly to the LOGIN prompts
