CoreBuilder® 7000HD Switch
High-performance, high-availability ATM switching with integrated 10/100 and Gigabit Ethernet The 3Com CoreBuilder Switch product line has been placed on End of Life Notice.

The CoreBuilder 7000HD switch is an integrated switching system for both the core and the edge of the enterprise ATM network.

The 3Com CoreBuilder® 7000HD switch is a uniquely versatile, modular, chassis-based switching system that delivers high performance and high availability for both the core and the edge of an enterprise ATM network. Configurable as either a pure ATM switch or as an integrated system for both ATM and high-throughput local area network (LAN) switching, the CoreBuilder 7000HD switch provides the full benefits of ATM in the core while also solving the major challenge of ATM networking today—how to connect high-speed Ethernet LANs into an ATM backbone without loss of end-to-end performance.

First to market with high-performance, integrated ATM/LAN switching for Ethernet, Fast Ethernet, and Gigabit Ethernet, the CoreBuilder 7000HD switch is now the most popular platform for solving this networking challenge. Tens of thousands of units are currently proving themselves under harsh, uncompromising conditions in production networks around the world. Based on redundant 5 Gbps full-duplex, nonblocking ATM switching engines and 3Com’s industry leading ZipChip™ ASIC technology for wire-speed packet-to-cell conversion, no other vendor comes close to matching the performance or versatility delivered by the CoreBuilder 7000HD switch for integrated ATM/LAN switching.

This powerful flexibility allows servers, desktops, workgroup switches, and other devices to attach to a CoreBuilder 7000HD switch easily, using either the simplicity of high-speed Ethernet technology or the high functionality of ATM.

Key Benefits
(The F.A.C.T.S.)
Flexibility: Simplify internet-working and make virtual networking practical with centralized configuration services, intuitive administration tools, and built-in fast setup wizards.

Availability: Increase reliability and ensure nonstop networking with redundant switching engines and multiple active backbone links for load sharing and fault tolerance.

Convergence: Integrate voice and video with data traffic over the network backbone through advanced Quality of Service (QoS) and traffic management capabilities.

Throughput: Speed up response time for Ethernet-attached clients from distributed applications and servers that are centralized across the backbone by employing the industry’s highest throughput from 10/100 and Gigabit Ethernet to ATM.

Scalability: Progress with ample growth potential in terms of speed, distance, and network size relying on scalable bandwidth, high port density, and multiple interface options that can be directly connected to SONET/SDH and native ATM services.
