Foundation for the IP Next-Generation Network

The Cisco CRS-1 Carrier Routing System marks a new era in carrier IP communications by powering the foundation for network and service convergence today while protecting investments for decades to come. The Cisco CRS-1 8-Slot Single-Shelf System is a massively scalable routing system that integrates multiple POP functions while providing the service flexibility, continuous system operation, and system longevity of the CRS-1 platform in a half-height configuration.

The Cisco CRS-1 8-Slot Single-Shelf System:

• Consists of a single, 8-slot, 40-Gbps-per-slot line-card shelf for a total switching capacity of 640 Gbps
• Features a midplane design based on a line-card shelf built from a line-card chassis
• Protects investments by using modular services cards (MSCs) and physical layer interface modules (PLIMs) that are fully interchangeable across the entire CRS-1 product family
• Contains slots for eight MSCs and four fabric cards in the rear of the chassis, and eight PLIMs and two route processors or additional distributed route processors in the front of the chassis
• Accommodates four fabric cards in the rear of the chassis, which perform Stage 1, Stage 2, and Stage 3 switching supporting service-intelligent fabric-based queuing and multicast replication
