H640GR-02 features:
  • Uptime
  • 1490nm signal level receiving on ONT
  • 1550nm signal level (CATV) receiving on ONT
  • ONT to OLT distance in meters
  • LAN ports state
  • Active MAC addresses
  • Multicast groups watched on connected STB
  • VoIP gate state and FXS ports (hook on/off, call in progress)
  • Disconnect reason (ONT turned off, damaged fiber between ONT and OLT)
  • IP addresses received from DHCP on IP interfaces
  • Firmware versions (active and standby)
  • Optical power level - possibility to define alarms on low/high power level
  • and many more
Configuration and provisioing from OLT:
  • Bandwidth limitation from  OLT to ONT per LAN port (traffic shapping)
  • Bandwidth limitation from  OLT to ONT per LAN port group (traffic shapping)
  • Assured and additional bandwidth in upstream
  • Multicast group filtering per LAN port on ONT (Conditional Access)
  • Defining maximum multicast groups number watched on LAN port
  • Sending multicast to OLT
  • QinQ support
  • Filtering VLANs on ONT
  • Both directions VLAN translation (mapping)
  • Hybrid port support: 1 untagged VLAN; other VLANs tagged on port
  • Any configuration of LAN ports – speed and activation/deactivation
