H18EDD-0402B Ethernet Demarcation Device


Overview

H18EDD-0402B is a carrier-class Ethernet demarcation 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, QoSpolicy, security mechanism, and other service optimization measures. Meanwhile,it features excellent extensibility and reliability.

H18EDD-0402B device provides two GE optical ports as NNIs, four GE electrical ports as UNI ports, and one FE electrical port as out-of-band management port, and its CONSOLE port is RS232.H18EDD-0402B supports the latest carrier Ethernet attributes and is compatible with IEEE, ITU, and MEF standards. The carrier-class OAM has enhanced network management capacity and meet 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 provide service for hundreds of enterprise users and hundreds of thousands of individual users.
