In the diagram above, the LAN Interface 128.1.1.1 is attached to the IP network 128.1.0.0. The WAN
Direct Host Interface represents LAN Interface 128.1.1.1 and allows the remote IP hosts to share the
network address space of 128.1.0.0. The WAN Interface 192.1.1.1 is logically attached to the IP
network 192.1.1.0. The RLAN Interface 100.1.1.1 is logically attached to the IP network 100.1.1.0.

YSTEM OMPONENTS
The major components of the SmartSwitch Remote Access Module are:
• System hardware consisting of a module and an administration port provided by the platform.
• System software specific to the SmartSwitch Remote Access Module, adapter modules, and
administration functions.
• Administration software that provides configuration, diagnostics and maintenance on the
system.
• System files containing configuration and operational information.
• Remote ISDN devices which interoperate with the system and allow device access to network
resources.
More detailed descriptions of system software and hardware are included in the next two chapters.
The following section describes remote ISDN devices.

EMOTE EVICES
The SmartSwitch Remote Access Module provides a centralized concentrator function for remote
ISDN devices. The devices can be separated into the following categories:
• remote ISDN bridge devices
• PC based terminal adapters
• ISDN enabled workstations
• other ISDN routers
Typical remote ISDN bridges provide one Ethernet port and one basic rate ISDN port. The basic
rate port is connected to the switched digital network and is used to make connections to the
SmartSwitch Remote Access Module. The Ethernet port is used to connect to a remote LAN. The
remote bridge device sends Ethernet frames from devices on the remote LAN over the switched
network.
PC-based terminal adapters connect to a remote personal computer and use the switched digital
network to connect to the system. The terminal adapter sends network protocol specific frames
from the host PC device over the switched network.
Workstation-based terminal adapters connect to a workstation and use the switched digital
network to connect to the system. The terminal adapter sends network protocol specific frames
from the workstation over the switched network.
