IP/MPLS RAN Transport

7705 SAR – 8-Slot Version

A complete Alcatel-Lucent IP/MPLS RAN transport capability can be built around the Alcatel-Lucent IP/MPLS portfolio (see Figure 1). Each product has undergone rigorous testing to ensure that the network you build provides you with unparalleled reliability, so your service offerings stand out in this highly competitive market. In order to provide the most efficient transport solution, the 7705 SAR employs pseudowire (PWE3) encapsulation methods to map services end to end. The use of pseudowires ensures that the key attributes of the transported service are maintained, while a cost-effective packet environment is used to perform aggregation.

7705 specifications

The Alcatel Carrier Internetworking Solutions (CIS) 7705 is a state-of-the-art platform designed to meet the demands of modern telecommunications networks. As part of the Alcatel-Lucent portfolio, the 7705 serves various use cases, including mobile backhaul, residential broadband, and business services, making it a versatile option for service providers.

One of the standout features of the 7705 is its scalability. The device supports numerous interfaces and can handle varying traffic loads, making it suitable for both small and large network environments. Its modular architecture allows operators to add capacity and interfaces as needed, ensuring that it can grow alongside the requirements of the network.

Another critical aspect of the 7705 is its support for multiple networking technologies. It incorporates MPLS (Multiprotocol Label Switching) capabilities, enabling efficient traffic engineering and quality of service (QoS) management. This support ensures that critical applications receive prioritized bandwidth while non-essential traffic is balanced effectively.

The 7705 also features advanced Ethernet services. With comprehensive Layer 2 and Layer 3 capabilities, it caters to diverse traffic types, including Layer 2 VPNs (Virtual Private Networks), E-Line, and E-LAN services. This flexibility makes it an excellent choice for service providers aiming to deliver differentiated offerings for residential and enterprise customers.

High availability is another critical characteristic of the 7705. The platform includes built-in redundancy features, such as hot-swappable components, ensuring minimal disruption in the event of hardware failure. This reliability is crucial for service providers who require continuous network uptime.

Moreover, the 7705 is designed with energy efficiency in mind. Its compact form factor and advanced power management features enable operators to minimize energy consumption and reduce operational costs. This focus on sustainability is increasingly relevant in today's environmentally conscious market.

Security is also integrated into the 7705 architecture. It supports various encryption protocols and authentication mechanisms, ensuring that sensitive data remains protected during transmission. As operators face evolving threats, the built-in security features of the 7705 provide peace of mind.

In summary, the Alcatel Carrier Internetworking Solutions 7705 stands out as a robust networking solution for modern telecommunications demands, offering scalability, extensive technology support, high availability, energy efficiency, and strong security features. With these characteristics, the 7705 positions itself as a reliable choice for service providers seeking to enhance their network infrastructure.
