H20PN-181 series PTN CPE

Overview

H20PN-181 series PTN (packet transport network) CPE (Customer Premise Equipment) device from Beijing Huahuan Electronics Co., Ltd, on the basis of high-performance L2 switch service, provide 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 series, including H20PN-181-2GX.4GE-P, H20PN-181-2GX.2GE.4E1-SP, can provide GE interface, GX interface, E1 interface, RJ-45 NM port, and RJ-45 CONSOLE port and clock interface.

H20PN-181 series support the latest carrier Ethernet attributes and is compatible with IEEE, ITU, and MEF standards. These series devices apply packet transmission technology, support complete OAM function, convenient for network management and maintenance, 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. Support connection-oriented MPLS-TP technology; support complete alarm and performance management function.
