DATA SHEET E4G-400 Cell Site Aggregation Router HIGHLIGHTS The Extreme Networks E4G-400 cell site aggregation router delivers Ethernet, IP/MPLS and pseudowire capabilities in a compact 1RU form factor. The E4G-400 provides mobile operators the ability to manage and aggregate TDM and Ethernet services and their associated protocols onto an economical and efficient Ethernet mobile backhaul infrastructure. • Optional industry-standard TDM pseudowires – supports up to 16 TDM ports and 256 total pseudowires • Optional 10 Gigabit Ethernet ports – up to 6 ports • Increased Gigabit Ethernet ports – 28 active GbE ports • Certified synchronization – both IEEE 1588v2 and SyncE Overview For service providers, revenue growth is increasingly driven by 3G and eventually 4G mobile services that provide access to compelling smartphone and tabletbased applications. The challenge in designing true 4G mobile backhaul is to build a foundation that protects existing investments in 2G and 3G services, provides a superior subscriber experience, prepares for future 4G service requirements, and minimizes costs. This challenge can be met by deploying a true 4G mobile backhaul network with three key ingredients: resiliency, synchronization and performance. Extreme Networks E4G-400 router is a carrier-grade Ethernet platform that provides a seamless migration path from TDM circuits to Ethernet services for mobile operators and creates a fundamental Ethernet infrastructure capable of scaling to the needs of 2G, 3G and 4G mobile networks. • Carrier-grade resiliency – through EAPS (Ethernet Automatic Protection Switching, RFC 3619) or ITU-T G.8032 Ethernet Ring Protection standard The E4G-400 is a cell site aggregation router providing up to 28 GbE ports and • Integrated Ethernet OAM – support for IEEE 802.3ah, IEEE 802.1ag, and ITU Y.1731 are located in closer proximity to the cell site aggregation switch). The E4G-400 its line-rate GbE and 10 GbE performance and support for IPv6 in hardware. • Stacks up to 8 units for incremental scale and growth as needed Product Description six 10 GbE ports in a 1RU form factor. Additionally, the E4G-400 router provides an optional 16-port T1/ E1 interface module to address the pseudowire capability that may be required at various points in the network (i.e. where 2G/3G cell towers aggregation router offers services capacity as well as subscriber scalability through Multiple resilient GbE Ethernet Transport rings can be provisioned to support thousands of cell sites due to the line-rate performance and port density of the E4G-400, and through its support for EAPS and ITU-T G.8032. For end-to-end clock synchronization to deliver predictable multi-service performance, the E4G-400 router can be SyncE-enabled. IEEE 1588v2 is also supported, and one or both of these protocols can be utilized depending on the deployment scenario, giving mobile operators the flexibility to choose the option that best suits their needs. For service assurance and management of SLAs, Extreme Networks E4G-400 router supports advanced OAM capabilities including IEEE 802.3ah Link OAM, IEEE

802.1ag Service OAM and ITU-T Y.1731 Performance Monitoring. Up to 6 optional active 10 GbE ports allow service providers The E4G400 also supports MPLS, which can provide a cost- to create protected rings and to interconnect to more effective and resilient mobile backhaul network that connects to networking services. the widely deployed MPLS mobile core infrastructure. 28 active GbE ports allow service providers to connect more • With advanced routing and switching features such as MPLS, 4G base stations and to trunk more cell sites together for IPv6, Ethernet OAM and others, the E4G-400 is future...

Flexible Port Configuration For E4G-400, with four dedicated Gigabit Ethernet fiber ports and four shared Gigabit Ethernet fiber ports, the switch can have up to 8 fiber GbE ports, while still providing 20 Gigabit Ethernet copper ports. If higher density copper ports are required, the switch can provide up to 24 Gigabit Ethernet copper ports while providing 4 Gigabit Ethernet fiber ports. Through the two option slots, E4G-400 switches can be equipped with an additional six 10 Gigabit Ethernet ports.
