Device	Description
SuperStack II Switch 3000	SuperStack II Switch 3000 is a Fast Ethernet
	switch. It allows Fast Ethernet switching and
	connectivity form Fast Ethernet to ATM. It
	can be used as a Backbone switch to
	connect multiple LS1000 devices, thus
	creating a FE/Ethernet network. It can be
	segmented into multiple bridges to allow
	virtual LAN. The Virtual LAN is both
	encapsulated based when connected as Fast
	Ethernet Backbone or LAN Emulation when
	connected to ATM Backbone.
CoreBuilder 2500	CoreBuilder 2500 is a high end switch. It
	allows Ethernet, FDDI, Fast Ethernet
	switching and connectivity form legacy LANs
	to ATM. It also allows routing to fulfill the
	function of routing between vLAN as well as
	IP, IPX and other protocol routing. The FDDI
	connectivity allows it to be the FDDI
	backbone edge switch. It can be segmented
	into multiple bridges to allow virtual LANs.
	The virtual LAN is LAN Emulation based
	when connected to the ATM Backbone.
CoreBuilder 5000 Switch Modules	The CoreBuilder 5000 device is a
	Multifunction hub. It is an Ethernet, FDDI
	HUB and has the switching capability of
	ATM, and Ethernet. It also allows
	connectivity form legacy LAN to ATM. It can
	be segmented into multiple bridges to allow
	virtual LANs. The Virtual LAN is LAN
	Emulation based when connected to ATM
	Backbone.
CoreBuilder 4000/CoreBuilder	CoreBuilder 4000 is an ATM switch, used in
5000 Switch	an ATM network and serves as an LE
	services entity as well.
Netbuilder II	NetBuilder II is a high perfromance
	multi-protocol router for LAN and WAN
	environments. In the ATM and VLAN
	environments it can be used as an inter
	VLAN one-armed router connected to the
	ATM backbone.
