Cisco CRS Modular Services Card Revision B
Data Sheet
Cisco CRS Modular Services Card Revision B
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
designed for always-on operation while scaling system capacity up to 92 Tbps. The innovative
system architecture combines the Cisco Silicon Packet Processor, the first programmable 40Gbps application-specific integrated circuit (ASIC), with the Cisco Service Separation Architecture
for unprecedented service flexibility and speed to service. The Cisco CRS-1 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.
This data sheet provides detailed product specifications for the Cisco CRS-1 Modular Services
Card Revision B. For more information about the Cisco CRS-1 or about other interfaces available

Key Features and Benefits
The MSC-B offers many advantages●
Supported across 4-slot, 8-slot, 16-slot and Multi-chassis CRS-3 chassis
Supported across all the CRS-1 form factors: 4-slot, 8-slot, 16-slot and Multi-chassis
Powered by the Silicon Packet Processor (SPP), one of the world’s most sophisticated 40
Features two Silicon Packet Processors (SPP)- one for ingress, one for egress packet
Always paired with Interface Module (IM) through the chassis mid-plane, thus occupying
one-half of a slot.
Can be paired with a variety of Interface Modules (IM) providing deployment flexibility
Layer 3 forwarding engine of the CRS-1 with an industry leading wire rate performance at
40 Gbps
Additional services of Class of Service (COS) processing, Multicast, Traffic Engineering
(TE), including statistics gathering, are also performed at 40Gbps line rate
Supports several forwarding protocols, including IPv4, IPv6, and MPLS
Enhanced performance with hardware based prefix lookup for IPv4, IPv6, and MPLS
Better environmental features with a lower power and weight profile
