Description The CoreBuilder 7000 switch is ideal for mission-critical operation where uncompromising reliability is essential. The system hardware incorporates support for redundant hot-swappable switching engines with automatic failover, load-sharing redundant power supplies, hot-swappable interface cards, and dual passive backplanes. Besides fully redundant hardware components, the CoreBuilder 7000 switch provides redundant, ATM Forum-compliant LANE services to ensure interruption-free switching of traditional LAN traffic over the ATM backbone. In case of an unforeseen failure of the primary LANE services, backup services on another CoreBuilder 7000 switch in the network are instantly activated. The switch also supports resilient mesh topologies with automatic rerouting around failures and dynamic load sharing over redundant links through 3Coms implementation of the ATM Forums Private Network Node Interface (PNNI) 1.0 specification. With the CoreBuilder 7000 switch, there is no need to compromise on versatility, performance, or reliability when selecting a data center, wiring closet, or building a core switch for an enterprise ATM backbone.
