H18EDD-2402B is a 24-port Ethernet aggregation and access device produced by Beijing Huahuan Electronics Co., Ltd.On the basis of high-performance L2 switch service, the device provides convenience of maintenance and deployment, multi-service support, carrier-class OAM management, reliable protection mechanism, QoS policy, security mechanism,and other service optimization measures. Meanwhile, it features excellent extensibility and reliability. H18EDD-2402B is a 1U rack-mounted device,which can aggregate 24 media converters. It provides 2 GE optical ports, 2 GE electrical ports and 24 FX optical ports, which can be configured to UNI or NNI ports flexibly, 1 FE electrical port as out-of-band management port, and RS232as CONSOLE port. H18EDD-2402B supports the latest carrier Ethernet attributes and conforms to IEEE, ITU, and MEF standards. The carrier-class OAM has enhanced network management capacity and meets the operator’s requirements for comprehensive and powerful capacity of monitoring and management. QoS function has extended the scope of carrier Ethernet, applying it to real-time service,i.e. voice and video. S-VLAN ID is used to implement VLAN extensibility and provides service for hundreds of enterprise users and hundreds of thousands of individual users. Features -FX optical ports support auto-negotiation mode and 100M full-duplex manual mode; GE optical and electrical ports support auto-negotiation mode and 1000M/100M full-duplex manual mode, as well as AUTO-MDIX, i.e. automatically identify crossover or straight-through networkcables. -IEEE802.1Q VLAN, IEEE802.1ad VLAN (at most 4094 VLAN entries).
