The Cisco ® CRS-1 Carrier Routing System is the industry's first carrier router offering continuous system operation, unprecedented service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS ® XR Software, a unique self-healing, distributed operating system. As part of a video-enabled IP Next-Generation Network (NGN), the Cisco CRS-1 Series delivers continuous, always-on operation that easily scales to support the massive bandwidth requirements of visual networking experiences such as high-definition IPTV and Cisco TelePresence TM. These services demand a platform that delivers predictable forwarding performance and efficient, intelligent fabric-based multicast replication. The Cisco CRS-1 Series enables the Internet and NGNs to handle the approaching zettabyte era of carrier IP communications while protecting network investments for decades to come.

Product Overview

The Cisco CRS-1 Series 2 Port 10 Gigabit Ethernet WAN/LAN-PHY Flexible Interface Module (Figure 1) provides two ports of IEEE 802.3ae-compliant 10 Gigabit Ethernet WAN/LAN-physical (PHY) layer interfaces and two available Cisco I-Flex shared port adapter (SPA) slots. By providing service intelligence, modularity, and configuration flexibility with fully compatible SPAs, the Cisco I-Flex design offers carriers long-term savings and the ability to handle evolving service delivery requirements, such as SONET-to- Ethernet.
The SPAs can be a mix of Ethernet or Packet over SONET/SDH (POS), and are identical to the SPAs used in other Cisco platforms such as the Cisco XR 12000 Series and the Cisco CRS Carrier Routing System. Gigabit Ethernet physical interface characteristics can be selected using different modular Small Form-Factor Pluggable (SFP) optics: short, long, extra long, and copper interfaces are supported. Extensive per-port and per-VLAN counters simplify network performance monitoring and troubleshooting.
