Additional functions of the ISDN interface

All LANCOM Office provide an ISDN connector, which offers some additional
functions.
Multiprotocol router
Via the ISDN interface other protocols than IP can be routed also . For exam-
ple, the IPX protocol enables the coupling of Novell networks.
LANCOM router offer a special feature for the interconnection of Microsoft
peer-to-peer networks. With the integrated routing of NetBIOS/IP packets,
the linking of Windows networks becomes a simple task. The remote stations
with which NetBIOS information have to be exchanged are registered in a
special list in order to avoid that each NetBIOS packet triggers a connection.
Acting as a NetBIOS proxy then, the router answers all inquiries regarding
known computers locally, and avoids in this way an unnecessary establish-
ment of connections.
Compatibility by PPP
The router supports communication with products of other vendors. Espe-
cially PPP is a very widespread protocol for the interchange of network data
via point-to-point connections.
Remote configuration using PPP
A special configuration highlight of LANCOM is the PPP-based remote man-
agement for routers, which cannot and should not be set up locally. A new
device has just to be supplied with voltage and to be connected with its WAN
interface. Then you can dial-in to the router simply over a PPP connection and
configure it comfortably from your specific remote location. This access is
protected by a password after the initial configuration and remains locked for
unauthorized callers.
Security features for the ISDN interface
To secure the integrated ISDN interface, the LANCOM Office uses password
protection and caller identification (CLI), as well as the callback function to
restrict connection establishment to previously specified ISDN subscriber
numbers. Furthermore, additional PPP authentication mechanisms enhance
the security concept.
