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. 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 20-Port Gigabit Ethernet Flexible Interface Module (Figure 1) provides 20 ports of IEEE
802.3-compliant Gigabit Ethernet 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.
