H18EDD-0204P-8E1 Ethernet demarcation device,on the basis of high-performance L2 switch service, 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.

This type of device provides four GE optical ports as NNIs, two GE electrical ports as UNI ports, eight E1 service interfaces and one FE electrical port as management ports, and its CONSOLE portis RS232. H18EDD-0204P-8E1 supports the latest carrier Ethernet attributes andis 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.
