Shanghai Cable Network Co., which serves more than 3.5 million cable homes, selected Cisco Systems for a major upgrade to its network. SCN selected Cisco 12000 Series routers for the core, Cisco ONS 15454s for optical transmission, and Cisco Catalyst 6509 and Catalyst 4507 switches for the aggregation layer. At the network edge, SCN selected the Cisco 10000 to aggregate Ethernet customers, and Cisco uBR10012 and 7246VXR cable modem termination systems (CMTS) to aggregate cable broadband traffic. In addition to cable TV, SCN plans to offer a suite of integrated next generation IP services including multimedia broadcasting, high-speed Internet access, digital television, videoconferencing, VoIP, VPNs, and long-distance education for both residential and commercial customers.
