9W006 and 9W007 23T HE SMART SWITCH R EMOTE ACCESS M ODULESystem ComponentsIn the diagram above, the LAN Interface 128.1.1.1 is attached to the IP network 128.1.0.0. The WANDirect Host Interface represents LAN Interface 128.1.1.1 and allows the remote IP hosts to share thenetwork address space of 128.1.0.0. The WAN Interface 192.1.1.1 is logically attached to the IPnetwork 192.1.1.0. The RLAN Interface 100.1.1.1 is logically attached to the IP network 100.1.1.0.S YSTEM COMPONENTSThe 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, andadministration functions.• Administration software that provides configuration, diagnostics and maintenance on thesystem.• System files containing configuration and operational information.• Remote ISDN devices which interoperate with the system and allow device access to networkresources.More detailed descriptions of system software and hardware are included in the next two chapters.The following section describes remote ISDN devices.R EMOTE ISDN D EVICESThe SmartSwitch Remote Access Module provides a centralized concentrator function for remoteISDN devices. The devices can be separated into the following categories:• remote ISDN bridge devices• PC based terminal adapters• ISDN enabled workstations• other ISDN routersTypical remote ISDN bridges provide one Ethernet port and one basic rate ISDN port. The basicrate port is connected to the switched digital network and is used to make connections to theSmartSwitch Remote Access Module. The Ethernet port is used to connect to a remote LAN. Theremote bridge device sends Ethernet frames from devices on the remote LAN over the switchednetwork.PC-based terminal adapters connect to a remote personal computer and use the switched digitalnetwork to connect to the system. The terminal adapter sends network protocol specific framesfrom the host PC device over the switched network.Workstation-based terminal adapters connect to a workstation and use the switched digitalnetwork to connect to the system. The terminal adapter sends network protocol specific framesfrom the workstation over the switched network. |
