compatible with the CRS-1 system. Apart from the single-chassis system and the multi-chassis system, CRS-3 supports back-to-back configuration as well. In this configuration, two Line Card
Chassis are connected back-to-back and there is no Fabric Card Chassis involved as in the case of a multi-chassis configuration. This configuration works only for the 8-slot and 16-slot chassis models. CRS-3 also supports

Systems has announced the addition of a new product to its existing CRS family, the Carrier Routing System X, or CRS-X (C-R-S-Ten), which is expected to be 10 times faster than the first CRS model (CRS-1) the company offered, back in 2004. CRS-X is said to be a 400 Gbit/s per slot system

A standalone
Carrier Routing System is deployed with a Line card chassis (LCC). The three main functional units of this LCC are the Line cards, Switching fabric and Route processor. The Line card consists of the physical interface card and a modular services card. The physical connectivity could be

which is said to be designed for high-end carrier grade routers and was launched with CRS-1. In a multi-chassis deployment, the Line card chassis is used along with another variety of chassis called as the Fabric Card
Chassis (FCC). The architecture enables scalability by increasing the number of

providers and large enterprises. It supports a wide range of interface speeds and types such as channelized OC3, OC12 to OC768 on Packet over SONET and from 1GE, 10GE all the way to 100GE on the
Ethernet technologies. A standalone CRS-3 system can handle 2.2 Tbit/s and a multi-chassis system
239:
The CRS-3 is the second generation of the CRS series launched in March, 2010. In CRS-3 each line card slot has a capacity of 140 Gbits/s, which is more than three times the capacity of the previous CRS-1 generation. The architecture is retained as in the previous generation and hardware is

photonic CPAK to reduce power consumption, heat dissipation and increase 100 GE port densities by a factor of three compared to competitive solutions. The
Universal Port concept adds the option of using a 100G port as 2 ports of 40G or 10 ports of 10G. 40G can again be used as 4 ports 10G. This

Cisco states that the CRS-X can be used in back-to-back & multi-chassis deployments and that CRS-1, CRS-3 & CRS-X can co-exist in a multi-chassis setup. The press release (reference) also claims that, the CRS-X 400 GE Line Card with Cisco AnyPort
Technology uses Cisco’s

and is backward compatible with the previous generation HW. At the time of launch, CRS-X family has three different flavors of physical interface card (40x10GE, 4x100GE and 2x100GE-Flex-40) apart from the improved fabric and modular service cards.

The CRS Line card chassis comes in three different flavors: 4-slot, 8-slot and 16-slot. The number of slots indicates the number of line cards that the chassis can accommodate. There is only one variety of Fabric card chassis.
