Cisco 8pt OC12/STM4 POS Shared Port Adapter
Part Number: SPA-8XOC12-POS
Demand for high-capacity corporate backbones, for high-speed access to the global Internet, and for trunking connections for service provider internetworking have led to growth in clear channel T3/E3 connections that has outpaced all other types and speeds of leased lines. This growth places tremendous strain on service providers and network managers who must provision and manage new T3/E3 connections. The Cisco® Clear Channel T3/E3 Shared Port Adapters (SPAs) Version 2 for the Cisco 7600 and Cisco ASR 1000 and ASR 9000 Series Aggregation Services Routers offer high-density, highly manageable T3/E3 line connectivity and termination. With integrated line-interface data service units (DSUs) that allow T3/E3 lines to be directly terminated on a Cisco router, the Cisco Clear Channel T3/E3 SPAs Version 2 simplify T3/E3 line management, reduce provisioning costs, and make valuable rack space available.
The Cisco Interface Flexibility (I-Flex) approach combines SPAs and SPA interface processors (SIPs), providing an extensible design that enables service prioritization for data, voice, and video services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership.
