  • IEEE 802.3ah Ethernet in the First Mile (EFM) 2Base-TL Solution
  • MEF Certified Ethernet Capabilities
  • Rapid Service Deployment
  • Superior Rate and Reach
  • Low Delay and Jitter for Voice and Video Transmission
  • Worldwide Spectral Compliancy
  • Environmentally Hardened

The ML620 EAD platforms can be managed In- and Out-of-Band by the MetaASSIST™ View graphical craft application and via the multi-platform Element Management System, MetaASSIST EMS. The management protocols include standard TL1 command line interface and SNMP using standard MIBs for seamless integration with third-party Network Management Systems (NMS).

The ML620 EADs provide full Carrier Ethernet over Copper access

functionality, including basic traffic management and QoS application at the edge. One hundred percent compatible with carrier Ethernet switching equipment in the CO, the ML620 provides basic bandwidth management and QoS at the edge, making the most efficient use of the bandwidth in the copper access network.
