Cisco Refurbished ASR 5500 Router Chassis - ASR55-CHS-SP-RF

As a mobile operator, the mobile broadband network that you built has forever changed the way that your customers work, live, play, and learn, and has become part of the very fabric of their everyday lives. However, mobile operators today face a significant challenge. Data traffic continues to grow exponentially, and regular network modifications are required to keep customers happy. New devices and applications are also drastically changing the way the network behaves. Competition in the mobile market is fierce, as the typical subscriber has multiple options for mobile service. At the same time, revenues are increasingly under pressure. It is an age-old dilemma - how does one reduce cost and increase revenue?

To overcome these challenges, operators must build their core networks with three essential attributes: flexibility, intelligence, and scale. A flexible network is one that can adapt to frequently changing business models, with the ability to make in-network design modifications without huge capital expenditures. An intelligent network is one that recognizes the myriad of different user behavior patterns, and has the tools in place to allow operators to monetize these patterns quickly and transparently. Finally, a scalable network is one that can address the demands of today's mobile network requirements as well as those that will evolve in the future. Data traffic is not just increasing; it is becoming more complex, requiring a scalable and flexible solution across all performance parameters - throughput, transactions, bearers, and sessions.

With all these factors, mobile operators need a mobile packet core solution that they can count on - one that provides efficient evolution to fourth-generation (4G) technology and small cells. Operators must plan for the 'new normal' of the mobile internet - elastic, flexible, virtual. This means being able to harness the right resources (intelligent performance) when you need them - instantaneously. This new normal starts with the intelligent performance of the Cisco ® ASR 5500 Multimedia Core Platform (Figure 1). Cisco ASR 5500 sets a new standard for intelligent performance that redefines the economics of the packet core. It is the first mobile platform designed for terabit performance that scales to tens of millions of sessions, and supports the transaction rates required to address the signaling surge.

Cisco ASR 5500 Architecture

As the newest member to the industry-leading Cisco ASR 5000 series, the Cisco ASR 5500 carries forward the existing ASR 5000 benefits of flexibility and intelligence, while providing substantial increases in scale and performance. The Cisco ASR 5500 is a high-capacity platform, specifically designed to satisfy the high performance, subscriber counts, and transaction rates of third-generation (3G) and 4G Long-Term Evolution (LTE) services plus the emergence of small cells.

The Cisco ASR 5500 supports an elastic architecture for mobile functions, in which these functions are based on software, not coupled to hardware. The ASR 5500 harvests system resources and applies them across the entire platform to optimize performance and maximize capital efficiency. This approach allows operators to deploy more efficient mobile networks that can support a greater number of concurrent calls, optimize resource usage, and deliver enhanced services, while also providing easy scalability.
