The Cisco 10000 Series six-port OC-3c/STM-1 Packet-over-SONET/SDH (PoS) Interface Module, combined with the high performance of the Cisco 10000 Series, revolutionizes the delivery of the edge services. This Cisco 10000 Series module is a high-capacity, high-performance interface that allows service providers to offer dedicated Internet access services, and peering to other service providers, at OC-3c/STM-1 rates (155 Mbps) on the Cisco 10000 Series. PoS allows Internet service providers (ISPs) to substantially increase the data load over their optical transport infrastructure. With its line-rate OC-3c/STM-1 capacity (155 Mbps), this Cisco 10000 Series module provides a powerful combination of scalability and flexibility. It also supports POS/SDH high-availability technology ideally suited for Internet and/or IP networks.
