H20RN Series are IPRAN Devices designed and produced by Beijing Huahuan, providing strong capacity, high port-density, and kinds of ports with very compact chassis. GE/FE/STM-1/STM-4/E1 ports are supported. The H20RN Series focus on edge ofproviders’ IP/MPLS transport network. They are very suitable for delivering L2 VPN, L3 VPN, and CES services for customers with end-to-end guaranteed availability, reliability and QoS to the key client. They are designed to help providers overcome challenges over resources, costs and services at the metro access layer, to bring values to both providers and their customers. Huahuan self-owned Unified NMS platform— EzView is offered for H20RN Series OAM.
