The network interface is the physical connection of the SmartSwitch Remote Access Module to a
data network. For example, the Ethernet resource in the system provides a network interface to an
Ethernet LAN. The ISDN lines in the system provide network interfaces to multiple remote
networks. Because of their switched nature, the ISDN lines provide virtual network interfaces. That
is, the same physical ISDN line can actually connect to different remote networks by dialing a
different phone number.
The SmartSwitch Remote Access Module provides a set of network interfaces that give you a wide
range of flexibility. The network interfaces provided by the system are:
•
LAN IP Network Interface
•
LAN IPX Network Interface
•
WAN IP Network Interface
•
WAN RLAN IP Network Interface
•
WAN RLAN IPX Network Interface
•
WAN (UnNumbered) Network Interface
The variety of network interfaces allows the installation of a wide range of devices at remote sites.
As illustrated below, you can simultaneously choose bridges, routers, or host devices based on the
specific remote site requirements.
