Cisco Lightstream ATM Switches

Cisco Lightstream ATM Switches are high-performance modular systems designed for enterprises requiring high-speed data transfer and mission-critical network reliability. Featuring a 5 Gbps non-blocking switch fabric, the Lightstream series ensures seamless integration of data, voice, and video over ATM networks.

The flagship Lightstream 1010 is built around a powerful MIPS RISC processor, providing the computational power necessary for advanced ATM signaling and routing protocols like PNNI. Its shared-memory architecture and large cell buffers (65,536 cells) minimize cell loss during peak traffic periods. Managed via the familiar Cisco IOS CLI or graphical tools like CiscoView, the Lightstream switches offer service providers and large enterprises a robust, standards-compliant foundation for Metro and Campus backbones.

Key Specifications:

• Capacity: 5 Gbps non-blocking throughput.

• Processor: 100 MHz RISC MIPS R4600.

• Connectivity: Supports up to 4 CAM modules with various PAM interface types.

• Traffic Management: Hardware-based support for ABR, EFCI, and intelligent packet discard.

• Resiliency: Hot-swappable components and optional redundant power supplies.
