It addresses your need for a cost-effective, scalable mobile radio access network (RAN) transport solution. The 7705 SAR excels at concentrating traffic at cell and hub sites, and adapting it to a normalized IP/MPLS infrastructure leveraging available media, especially scalable, cost-effective Ethernet. It is also extremely effective at the transport of legacy traffic such as T1/E1 private line transport over a modernized infrastructure. The 7705 SAR’s quality of service, traffic management, provisioning, troubleshooting and billing features make it possible for you to provide consistent, superior services to your customers. Its flexible, future-proof architecture will enable you to address evolving aggregation requirements. Built on the same architectural software base as the highly successful Alcatel-Lucent Service Router products, the 7705 SAR enables the creation of an endto- end solution for supporting and capitalizing on the growing mobile aggregation market. Market Requirements Traffic is steadily increasing on mobile networks, as the volume of mobile data and video traffic grows alongside voice. Unfortunately, the revenue per bit is not keeping pace with this growth. To make sure your business remains profitable, you need to find a new networking approach — one that enables you to reduce operating overhead and scale services cost-effectively. You need a solution that allows you to move forward with a next-generation infrastructure, while ensuring that you retain all the capabilities (and customers!) from your legacy services. In a highly competitive market, you must be able to meet customers’ expectations and offer a full range of differentiating services, backed with stringent service level agreements. Fortunately, by transitioning to an IP/MPLS infrastructure and an Ethernet-centric RAN, you can reduce costs while expanding services. The access network presents some unique challenges, as you need to be able to integrate diverse first mile media, including traditional n x T1/E1 copper, microwave, DSL and fiber. You can’t limit yourself to a subset of the options: you need to be able to support whatever access media can be most cost-effectively deployed in a given geography. And most importantly, you need a solution that can be readily integrated with your existing operations support system — a solution that makes that transition from a TDM-based RAN to a fully packetized model as painless as possible. You’ll want a partner with the know-how and experience to help you bring all aspects of your operations up to speed quickly. Finally, the transition you undertake in the RAN must be in keeping with your overall, long term evolutionary goal towards a flattened, all-IP mobile transport network, securely supporting a wide range of services. 7705 SAR: The Newest Star in an All-Star Lineup The 7705 SAR is an essential component of • Service-aware tools to facilitate operations, a pre-tested, pre-qualified, end-to-end managed administration, maintenance and provisioning and verified RAN networking and transport (OAM&P) tasks. solution.
