E4G Family
Extreme Networks E4G family enables mobile operators to deploy a true 4G mobile backhaul network to address the current requirements of 2G and 3G services while laying the foundation for a true 4G mobile broadband network.
E4G-200 Cell Site Router
Cell site router supports industry-standard TDM pseudowires, enabling the support of legacy voice services over an Ethernet mobile backhaul network.
E4G-400 Cell Site Aggregation Router
Highly scalable cell site aggregation router enables mobile operators to manage and aggregate TDM and Ethernet services onto a single, economical and efficient Ethernet mobile backhaul network.
