Used Cisco CRS-1 Multishelf Carrier Routing System
Part # CRS-1
 Product Description:
Cisco CRS Series - The Cisco CRS-1 Carrier Routing System
provides carrier IP communications by powering the foundation
for network and service convergence today while protecting
investments for decades to come. The Cisco CRS-1 Multishelf
System delivers the service flexibility, continuous system
operation, and system longevity of the Cisco CRS-1 platform,
scaling from 640 Gbps to 92 Tbps while in service with no
service disruption.
The Cisco CRS-1 Multishelf System consists of 2 to 72,
40-Gbps-per-slot line-card shelves and 1 to 8 fabric shelves for
a total switching capacity of up to 92 Tbps. It also supports
in-service upgrade from single-shelf to multishelf configuration
with the addition of 1 to 8 fabric shelves, as well as 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. The Cisco CRS-1
Multishelf System supports up to 1152 slots for MSCs, PLIMs, and
distributed route processors. It's feature line-card shelves are
connected only to the fabric-card shelves where Stage 2 of the
three-stage switching process is performed supporting true
fabric shelf redundancy, service-intelligent fabric queuing, and
massive multicast replication scale.
The CRS-1 (different from a GSR or a 7600), is built around a midplane. Each "line card"
(Modular Services Card) has a part that goes into the back and a part that goes in the front, called Physical
Layer Interface Module (PLIM). The MSCs are all the same and work with any kind of PLIM which are available for
different kinds of transmission media.
