Cisco's honking big CRS-1 is the switch AT&T is using to expand the reach of its 40G IP/MPLS backbone network to more than 50,000 miles in the United States, reports Network World. The Cisco Carrier Routing System (CRS-1), will extend 40Gbps from a core network to regional carrier locations, and will serve as the core platform for AT&T’s backbone expansion, the company says. The CRS-1, which Cisco unveiled in June 2004, has 1.2Tbps of capacity and 40Gbps of capacity per line card slot. Yahoo Broadband in Japan deployed the CRS-1 to upgrade its network to 40Gbps last year to meet customer demand for Internet access, VoIP and video-on-demand.
